This book and accompanying compact disc provide a rare insight in the innovative ways a community of Haitian migrants in South Florida has maintained religious traditions and familial connections. It demonstrates how religion, ritual, and cultural practices affect lives on both sides of the Caribbean, and it debunks myths of exotic and primitive vodou (often spelled "voo doo"), which have long been used against Haitians. As Karen Richman shows, Haitians at home and in migrant settlements make ingenious use of audio and video tapes to extend the boundaries of their ritual spaces and to reinforce the moral and spiritual anchors to one another. The book and CD were produced in collaboration to give the reader intimate access to this new expressive media. Sacred songs are recorded on tapes and circulated among the communities. Migrants are able to hear not only the performance sounds - drumming, singing, and chatter - but also a description, as narrators tell of offerings, sacrifices, prayers, and the exchange of possessions. Spirits who inhabit the bodies of ritual actors are aware of the recording devices and personally address the absent migrants, sometimes warning them of their financial obligations to family members in Haiti. The migrants' dependence on their home village is dramatically reinforced while their economic independence is restricted. Using standard ethnographic methods, Richman's work illuminates the connections among social organization, power, production, ritual, and aesthetics. With its transnational perspective, it shows how labor migration has become one of Haiti's chief economic exports.

The objective of the present study was to investigate the association between human T‐lymphotropic virus type‐1 (HTLV‐1) infection and cancer risk in a longitudinal study. The study population consisted of 2729 atomic bomb survivors in Nagasaki Prefecture, Japan, who had no previous history of cancer at baseline. The baseline survey, including analysis of antibody to HTLV‐1, took place during 1985–1987 and follow‐up was performed until the end of 2001. There were 553 incident cases of malignant neoplasms during the observation period. After adjustment for sex, age and other variables, HTLV‐1 infection was not associated with the risk of developing cancers of all sites, excluding adult T‐cell leukemia (rate ratio 1.0, 95% confidence interval [CI] 0.76–1.4), stomach, colon and rectum, lung, female breast or other minor sites, but was associated with increased risk of liver cancer (rate ratio 2.1, 95%CI 1.0–4.6). The point estimate of the rate ratio for thyroid cancer was 3.0, but this was not significantly higher than 1 because of the small number of events (n = 11) and low prevalence of HTLV‐1 seropositivity. These findings support the idea that HTLV‐1 infection is not associated with an increased general cancer risk. Confounding by hepatitis C virus (HCV) and the interaction between HTLV‐1 and HCV may explain the increased risk of liver cancer among HTLV‐1 carriers. Further follow‐up may be required to determine if HTLV‐1 carriers are at increased risk of thyroid cancer. (Cancer Sci 2006; 97: 535– 539)

Natural disasters occur all over the world and have massive effects. The impact of natural disasters has prompted various studies to find out the effects of a better mitigation and preparedness phase on individuals and communities in reducing the number of victims. Although revious literature are available that discuss disaster preparedness, studies that specifically assess the effectiveness of community-based disaster preparedness training are not available yet. This study aimed to identify effectiveness of community-based disaster preparedness training and which communication media are effective for use in disaster management in society. The literature reviews were conducted using the PRISMA model. The articles were collected from 4 journal databases, including EBSCO, Science Direct, Scopus dan ProQuest. Quality of each articles were assessed by Crowe Critical Appraisal Tool (CCAT). We identified a total of 3 studies. From the data extraction, 4 types of interventions were obtained in increasing disaster preparedness including phone-based intervention, printed media intervention, peer-mentored preparedness (PM-Prep) program and small group discussion intervention. The effectiveness of community-based disaster preparedness training is evidence that is needed to be applied in various countries due to the high prevalence of natural disasters worldwide.

The patterns of hepatic injury were studied in 100 patients with a diagnosis of sarcoidosis and clinical evidence of liver disease that led to diagnostic liver biopsy. Granulomas were present in all patients; they occupied from <1% to >90% of the total volume of tissue examined and were most often located in the portal/periportal region. In none of the 100 cases were infectious organisms identified by special stains, culture, or serology. In 99% of cases, these granulomas were noncaseating; in one of the 100 cases central caseation was noted. In addition to the granulomas present in all biopsies, three broad categories of histologic change were found: cholestatic (58%), necroinflammatory (41%), and vascular (20%). Among those with cholestasis, 19 patients had bile duct lesions similar to primary biliary cirrhosis, whereas another 13 had a pattern of periductal fibrosis reminiscent of primary sclerosing cholangitis. In 37 patients with chronic cholestasis, a decrease in the number of bile ducts (ductopenia) was noted. Twelve patients had an acute cholangitis suggestive of mechanical obstruction—although no clinical evidence of ductal obstruction was found. Necroinflammatory changes included spotty necrosis suggesting hepatitis of diverse etiologies (including viral infection and drug reaction) and chronic portal inflammation suggestive of chronic active hepatitis. Vascular changes consisted of sinusoidal dilatation (14 cases) and nodular regenerative hyperplasia (9 cases). In 6% of the patients, the only changes in the biopsy were those of granulomatous inflammation; each of these patients had a dominant mass (“sarcoidoma”), which had been biopsied to rule out tumor. Fibrosis was seen in 21% of the biopsies—periportal (13%), bridging (2%), or cirrhosis (6%). It is clear that sarcoidosis can cause progressive liver disease with a wide array of histologic features that can mimic those of other primary liver diseases

Abstract High-Impact Educational Practices (HEPs) are a set of specific teaching and learning approaches proven effective in university education. This paper focuses on the benefits derived from utilizing three particular HEPs (inquiry-based collaborative activities, undergraduate research, and experiential learning) while teaching a snow and ice field course titled “Silverton Field Experience.” Student evaluations and instructor feedback reinforce the notion that HEPs encourage deep learning. Deep learning is manifest through increased enthusiasm and participation as well as learning in ways that are meaningful, creative, and stimulating. In terms of pedagogy in geography, these HEPs also create an expanded sense of place and a new way to encourage spatial thinking. The HEPs outlined here are replicable in different geography sub-disciplines and among different settings in higher education and prove exciting to an audience of pedagogic researchers and teacher-practitioners in geographical education.

The incidence of childhood sexual abuse (CSA) in the general population, as well as the greater prevalence of CSA survivors among those who enter therapy, mean that therapists are likely to treat sexual abuse survivors in their clinical work. A modified Delphi study was used to collect data to determine how American Association of Marriage and Family Therapy (AAMFT) Approved Supervisors make treatment decisions following client disclosures of CSA. Three rounds of data were collected. The results suggested that there are several issues to address in therapy regardless of treatment modality and disclosure type. Suggestions for treatment were provided depending on the disclosure scenario.

Frankia BCU110501 induces nitrogen-fixing root nodules in Discaria trinervis (Gillies ex Hook. & Arn.) Reiche (Rhamnaceae) via intercellular colonisation, without root hair deformation. It produces diffusible factors (DFs) that might be involved in early interactions with the D. trinervis roots, playing a role in the nodulation process. The induction of root nodule development in actinorhizal symbiosis would depend on the concentration of factors produced by the bacteria and the plant. A detailed analysis of nodulation kinetics revealed that these DFs produce changes at the level of initial rate of nodulation and also in nodulation profile. Diluted Frankia BCU110501 inoculum could be activated in less than 96h by DFs produced by Frankia BCU110501 cells that had been previously washed. Biochemical characterisation showed that Frankia BCU110501 DFs have a molecular weight of <12kDa, are negatively charged at pH 7.0 and seem to contain a peptide bond necessary for their activity. Frankia BCU110501, belonging to Frankia Clade 3, does not induce nodules in Alnus acuminata H.B.K. ssp. acuminata but is able to deform root hairs, as do Frankia strains from Clade 1. The root hair deforming activity of Frankia BCU110501 DFs show the same biochemical characteristics of the DFs involved in nodulation of D. trinervis. These results suggest that Frankia symbiotic factors have a basic structure regardless of the infection pathway of the host plant.

L’universitarisation des etudes pour devenir professeur d’EPS, les transformations institutionnelles dans la formation des enseignants ont amene de nombreuses reflexions quant a la professionnalisation de ce metier et aux professionnalites qui y sont developpees. Le professionnel recherche par l’institution repond a un profil different selon les epoques : animateur, technicien-applicateur, ingenieur-regulateur, concepteur-praticien reflexif. L’etude de l’epreuve professionnelle du concours et de ses rapports de jury en atteste. Les propos tenus par les enseignants-stagiaires temoignent qu’ils convoquent finalement toutes ces professionnalites « historiques » pour faire face au « choc de la realite ».

Abstract A 32-kDa laccase-like stilbene oxidase was purified to homogeneity (one single band on SDS-PAGE) from Botrytis cinerea liquid culture medium enriched with pectin. Two major isoforms with p I 4.35 and 4.3 were revealed by isoelectric focusing (IEF). This enzyme oxidizes the grape stilbenic phytoalexins, resveratrol and pterostilbene. Syringaldazine is poorly oxidized by this stilbene oxidase as compared to the rate of stilbene oxidation. This enzyme catalyses the oxidation of resveratrol to ϵ-viniferin.

Abstract Mangrove plants comprise plants with similar ecological features that have enabled them to adapt to life between the sea and the land. Within a geographic region, different mangrove species share not only similar adaptations but also similar genetic structure patterns. Along the eastern coast of South America, there is a subdivision between the populations north and south of the continent's northeastern extremity. Here, we aimed to test for this north‐south genetic structure in Rhizophora mangle, a dominant mangrove plant in the Western Hemisphere. Additionally, we aimed to study the relationships between R. mangle, R. racemosa, and R. × harrisonii and to test for evidence of hybridization and introgression. Our results confirmed the north‐south genetic structure pattern in R. mangle and revealed a less abrupt genetic break in the northern population than those observed in Avicennia species, another dominant and widespread mangrove genus in the Western Hemisphere. These results are consistent with the role of oceanic currents influencing sea‐dispersed plants and differences between Avicennia and Rhizophora propagules in longevity and establishment time. We also observed that introgression and hybridization are relevant biological processes in the northeastern coast of South America and that they are likely asymmetric toward R. mangle, suggesting that adaptation might be a process maintaining this hybrid zone.

The purpose of this article is twofold: on the one hand, we stimulate a debate on the diffusion of an evaluative culture in developing countries at different levels (national, local and international); on the other hand, we suggest some perspectives for the analysis of export processing zones (EPZ) that are widely used by developing countries as a means to attract investment and promote exports. The paper offers a brief overview of the international debate on evaluation in developing countries and export processing zones and, through a preliminary study carried out in Egypt, it suggests a conceptual framework to analyse the effects of export processing zones on firms' production costs. The findings deal with issues of counterfactual estimation, choice of the evaluation question and relevant variables to consider in evaluating EPZs. Furthermore they confirm the feasibility of expanding the study at reasonable costs on bigger samples by using the same methodology.

Acne vulgaris is a common skin disorder that affects ∼70% to 87% of adolescents and young adults. (1) The pathogenesis of acne is multifactorial and complex, and is thought to be due to androgen-stimulated sebum production. This production leads to follicular occlusion and hyperkeratinization, with comedo formation, as well as microbial colonization of pilosebaceous follicles by Propionibacterium acnes , leading to inflammatory papules and pustules. Conventional treatments for acne include salicylic acid, benzoyl peroxide, retinoids, and antibiotics (topical and systemic). However, symptoms may not always improve, and patients may have adverse reactions to conventional treatments and thus seek alternative treatments. Antibiotic resistance in P acnes also has been rising, thus promoting the need to look at alternative therapies. (2)
The influence of diet on acne has been debated for decades. One review of the literature looking at the evidence for diet, face washing, and sunlight exposure in acne management concluded that the evidence is incomplete at best. (3) Another review did not support any link between acne and foods such as dairy products, chocolate, and fatty foods. (4) However, with more recent focus on diet and nutritional supplements, emerging research suggests that diet may be a factor, particularly in mediating the inflammation and oxidative stress of the acne process. (5)(6)(7)
Western diets, with characteristically high glycemic indices, can elevate insulin and insulin-like growth factor 1 levels acutely and chronically. (5) These hormones stimulate adrenal and gonadal androgen production, leading to increased sebum production and acne. Frequent consumption of high-glycemic-index carbohydrates may repeatedly expose adolescents to acute hyperinsulinemia. Therefore, a low-glycemic-load diet may have a beneficial effect on acne. (6)

territory he conquered. Thomas Bowrey wrote of him that he was " very charitable and a real lover of the English nation, all in general (that ever knew him) were enamoured (sic) with his perfections" (quoted p. 285). Yet he was prone to " opportunism, secretiveness and duplicity " (p. 288). Surely such a man is worthy of a more detailed study as a person than the bare three pages which Dr. Sarkar has entitled " Mir Jumla as a Man " (pp. 284-7). A. L. BASHAM.

Ultrathin resonant-cavity-enhanced solar cells based on less than 30 nm thick hydrogenated amorphous germanium (a-Ge:H) absorbers have the potential to replace standard micrometer-thick microcrystalline silicon absorbers in silicon thin-film solar cell technology, as they yield comparable infrared absorption. Combined with the concept of a folded solar cell on a three-dimensional structured ZnO honeycomb electrode, grown in a cost-effective scalable electrochemical process, the strong absorption of this ultrathin type of cell can be even further enhanced. Our results show an increase of 11% in the short-circuit current density of an a-Ge:H solar cell on a honeycomb electrode compared to a flat reference cell, with no detrimental effects in the electrical properties. The benefit in the optical performance is mainly related to a broadband increase in the quantum efficiency due to an increased absorber volume as well as suppressed interferences inside the front electrode. At the same time, the desired resonances inside the resonant-cavity-enhanced solar cell itself are maintained.

Patients with Leigh syndrome (LS) sometimes develop epileptic spasms (ES). ACTH treatment for ES may be effective without serious adverse events in some patients with LS. Status dystonicus is a life-threatening disorder characterized by an acute exacerbation of generalized dystonia and often develops as a triggered event. The underlying pathophysiology of status dystonicus remains unclear. To our knowledge, there has been no reported case of status dystonicus associated with ACTH treatment. Here, we describe the first reported patient with LS, harbouring compound heterozygous mutations in SLC19A3 gene, who developed status dystonicus following initial intramuscular injection of a course of ACTH treatment for ES. Stressors can precipitate acute exacerbation in SLC19A3-related disorders. Interestingly, in this patient, external discomfort stimuli tended to induce transient hypertonia with opisthotonos. This report suggests that attention should be paid to acute exacerbation of generalized dystonia when ACTH treatment for ES is started in patients with LS, who have dystonia tend to exacerbate transiently by external discomfort stimuli.

The article is devoted to the consideration of the continuing medical education (CME), which is a supplementary vocational education carried out through the implementation of qualification and further post-graduate training programs. The basic principles of the CME development in the Russian Federation are defined in the article. Among them: continuity in post-graduate training; harmonization with international standards; partnership of the state and professional organizations; comprehensive training of medical workers, that is convenient for them; the use of innovative technologies; quality control and independence, the motivation of employees to improve their skills. During the study the following methods were applied: analysis, comparison and observation. The author of the article outlines that the current regulatory framework for the CME development is the federal laws in the field of healthcare. The results of the study. The majority of doctors accepted a new model as a principal one and registered at the CME website for training. It is concluded that the fundamental difference between the new educational model and the traditional one is that in the СME system an individual 5-year cycle educational plan is drawn up, including 250 credits (hours) of educational activity, which are evenly divided into 50 credits (hours) annually. It is also stated that during the process of implementing the model, certain problems arose: a significant increase in the number of students per year, the increase in the number of organizations accredited for training since it is difficult to control it at the first stage. The СME model needs to be improved and developed, relying on all the best achievements and developments of the traditional system of post-graduate training of doctors.

TO THE EDITOR: We read with great interest the review article entitled "How to interpret a functional or motility test: colon transit study" by Kim et al.1 The authors reviewed colonic transit study using radio-opaque markers, scintigraphy and wireless motility capsule in evaluation of colonic motility.1 They described the method and criteria to differentiate between slow and normal transit constipation and fecal evacuation disorders. However, it is important to note that the method they described for assessment of colonic transit using radio-opaque markers, initially described by Hinton et al2 as early as 1969 may not suit the population with rapid gut transit such as in India.
The authors referred to several studies in which either single or multiple capsule techniques were used.1 In single capsule technique, after ingestion of markers contained in capsules, several abdominal X-rays are performed until all markers are defecated or a single abdominal X-ray on day 5 (120 hours later). Similarly, in multiple capsule-technique, capsules are taken daily for 3 days followed by abdominal X-rays on day 4 and 7 or only on day 7. In single capsule technique, when more than 20% of markers are retained, it is defined as delayed transit.3 Most of these series are from the West where mean colonic time was found to be 30-40 hours, with upper normal limit of 70 hours.4-8 However, this method was not found suitable in some Asian population especially in India where gut transit is fast.
Gut transit time is quite fast in Indian population. Though stool frequency of up to 3 per week is considered normal in Western population,9 99% of Indians pass at least 1 stool per day.10 Average stool weight in 514 healthy Indians older than 15 years was 311 g per day.11 In contrast, stool weight greater than 200 g per day is diagnostic of diarrhea in Western population.12 Median mouth to cecum transit time was 65 minutes among 12 healthy Indians13 and total colonic transit time was 15.8 hours among 25 subjects.14 Considering fast gut transit among Indians, the protocol for assessment of colonic transit time using radio-opaque markers is likely to be different in this population.
When the Western protocol for assessment of transit time by administration of 20 radio-opaque markers each at 0, 24 and 48 hours followed by an abdominal X-ray at 72 hours was used in Indian population, even at 72 hours, very few markers were found retained inside the abdomen due to rapid gut transit.10 Hence, attempts have been made to reduce the interval between ingestion of markers and abdominal X-ray.10 Nabar et al14 tried to administer markers initially according to the Western protocol; since most of the markers got expelled at 72 hours, they reduced the interval between administration of markers to 12 hours and then to 9 hours.
We performed colonic transit study15 using indigenously prepared radio-opaque markers (SGmark) in 9 patients with adult Hirschsprung's disease, 11 with chronic intestinal pseudo-obstruction and 11 healthy subjects. Twenty markers were administered each time at 0, 12 and 24 hours followed by abdominal X-rays at 36 and 60 hours. After 36 hours, total number of markers retained in the abdomen and those in the right segment in patients with Hirschsprung's disease and chronic intestinal pseudo-obstruction was higher than that in healthy subjects. In the abdominal X-ray at 60 hours, total number of markers and number in all segments were higher in patients with Hirschsprung's disease and chronic intestinal pseudo-obstruction than in healthy subjects. The best cut-off by receiver operating characteristic curves at 36 and 60 hours were 30 and 14 markers, respectively. The sensitivity, specificity, positive and negative predictive values, diagnostic accuracy and area under the receiver operating characteristic curve at 36 hours were 90%, 82%, 90%, 82%, 87% and 0.9, respectively; the corresponding values at 60 hours were 95%, 100%, 100%, 92%, 97% and 0.99, respectively. This study showed that an abdominal X-ray at 60 hours is better than that at 36 hours.
We conclude that colonic transit time varies markedly among different populations. It depends on race, ethnicity and dietary habits. The methods and normative data of one population may not be applicable to another population. Colon transit time should be standardized and validated for individual population. Our protocol of 12-hourly administration of markers should be followed for Indian population or other similar populations with rapid gut transit.

Epidermal growth factor receptor (EGFR) has become an attractive target for cancer molecular imaging and therapy. Affibody proteins against EGFR have been reported, and thus, we were interested in evaluating their potential for positron emission tomography (PET) imaging of EGFR positive cancer. An Affibody analogue (Ac-Cys-Z(EGFR:1907)) binding to EGFR was made through conventional solid phase peptide synthesis. The purified protein was site-specifically coupled with the 1,4,7,10-tetraazacyclododecane-1,4,7-tris-aceticacid-10-maleimidethylacetamide (maleimido-mono-amide-DOTA) to produce the bioconjugate, DOTA-Z(EGFR:1907). (64)Cu labeled probe (64)Cu-DOTA-Z(EGFR:1907) displayed a moderate specific activity (5-8 MBq/nmol, 22-35 microCi/microg). Cell uptake assays by pre-incubating without or with 300 times excess unlabeled Ac-Cys-Z(EGFR:1907) showed high EGFR-specific uptake (20% applied activity at 0.5 h) in A431 epidermoid carcinoma cancer cells. The affinity (K(D)) of (64)Cu-DOTA-Z(EGFR:1907) as tested by cell saturation analysis was 20 nM. The serum stability test showed excellent stability of the probe with >95% intact after 4 h of incubation in mouse serum. In vivo small-animal PET imaging showed fast tumor targeting, high tumor accumulation (approximately 10% ID/g at 1 h p.i.), and good tumor-to-normal tissue contrast of (64)Cu-DOTA-Z(EGFR:1907) spiked with a wide dose range of Ac-Cys-Z(EGFR:1907). Bio-distribution studies further demonstrated that the probe had high tumor, blood, liver, and kidney uptakes, while blood radioactivity concentration dropped dramatically at increased spiking doses. Co-injection of the probe with 500 microg of Ac-Cys-Z(EGFR:1907) for blocking significantly reduced the tumor uptake. Thus, (64)Cu-DOTA-Z(EGFR:1907) showed potential as a high tumor contrast EGFR PET imaging reagent. The probe spiked with 50 microg of Ac-Cys-Z(EGFR:1907) improved tumor imaging contrast which may have important clinical applications.

La prise de donnees phytoecologiques par l'IFN, dans le cadre des inventaires forestiers departementaux, a commence en 1981 a l'echelon de Montpellier (inventaire floristique seulement) et en 1985 a l'echelon de Nancy. Elle a ete generalisee a l'ensemble de la France a partir de 1992. Cet ensemble considerable de donnees (prevision d'environ 140 000 placettes pour une couverture complete de la France en 2005) est gere au sein de la base de donnees de l'IFN en liaison avec les donnees dendrometriques. L'IFN a pour souci de valoriser au mieux ces donnees en leur donnant une large publicite et en participant a des etudes scientifiques en collaboration avec d'autres organismes (INRA, ONF, ENGREF, CEMAGREF, AFOCEL...). Il s'agit ici de rappeler la methodologie de l'inventaire phytoecologique de l'IFN.

This article discusses cairns as ritual constructions during the Late Bronze and Pre-Roman Iron Ages in Southwest Norway. The basis for the discussion are two cairns from Somme in Sola, Rogaland. It is suggested that the cairns are part of rituals related to settlement expansion and a rapid transformation of the landscape during the period.

In this paper a new method which computes the optical flow from a sequence of time-varying images is presented. The use of second order derivatives of the image brightness provides a solution to the aperture problem. Experimental results on sequences of real images, together with estimates of 3D motion parameters, like time-to-crash for translation and angular velocity for rotation, are presented and discussed. Due to the remarkable accuracy which can be achieved in estimating motion parameters, the proposed method is likely to be very useful in a number of computer vision applications.

The three-dimensional (3D) flow below the interface of an evaporating liquid at a low pressure is visualized and quantified using scanning particle image velocimetry. The technique presented highlights the use of a single camera and a relatively fast moving laser sheet to image the flow for an application where using more than one camera is difficult. The technique allows collection of the full three-dimensional velocity vector map over the whole liquid volume. The out-of-plane component of the velocity has been determined using two different processing approaches: (i) deriving the full vector from a 3D cross-correlation of the particle volumes and (ii) applying the continuity equation to determine out-of-plane velocities from the calculated in-plane velocity vector fields. The results obtained from both methods showed good agreement with each other. The 3D velocity field reveals the existence of a torus shaped vortex below the evaporating meniscus that was induced by the exposure of the cold liquid to the warmer solid walls. The velocity data also shows that the maximum velocity occurs below the interface, not at the interface which highlights that the observed vortex is not driven by thermocapillary forces that usually govern the flow during evaporation at smaller scales.

Abstract The overtone band 2ν 0 8 of CH 3 CN around 720 cm −1 has been measured on a Bruker Fourier transform spectrometer at a resolution of 0.003 cm −1 . Only the parallel band was observed, but due to the l (2, 2) resonance, Δ K = −2 lines leading to the v 8 = 2, l 8 = −2 levels with K = 1-3 could be seen. More information for the l 8 = ±2 component of the vibrational state v 8 = 2 was evaluated from the hot band 2ν ±2 8 - ν ±1 8 . Altogether more than 1000 lines were assigned. In the fit pure rotational lines from literature were also combined. Among the results the anomalous A 0 - A ′ values 4.6722(13) × 10 −3 cm −1 for the 2ν 0 8 band and 7.0324(32) × 10 −3 cm −1 for the 2ν ±2 8 band are striking.

B cells play a major role in the pathogenesis of many autoimmune disorders, including rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and type I diabetes mellitus, as indicated by the efficacy of B cell–targeted therapies in these diseases. Therapeutic effects of the most commonly used B cell–targeted therapy, anti-CD20 mAb, are contingent upon long-term depletion of peripheral B cells. In this article, we describe an alternative approach involving the targeting of CD79, the transducer subunit of the B cell AgR. Unlike anti-CD20 mAbs, the protective effects of CD79-targeted mAbs do not require cell depletion; rather, they act by inducing an anergic-like state. Thus, we describe a novel B cell–targeted approach predicated on the induction of B cell anergy.

Thirteen (13) types of building tiles and Sharp sand commonly used for building purposes were collected for their radionuclide contents analysis using gamma ray spectrometry. The average value of the Radium equivalent activity is 208.81 Bq/kg for all samples considered was found to be lower than the recommended safe limit of 370 Bq/kg. Similarly, both external and internal hazard indices (Hex and Hin) were noted to have mean values of 0.57 and 0.73, respectively, which were lower than the recommended safe standard of 1. More so, the average absorbed gamma dose rate was observed to be 94.31 nGy/h, much higher than the recommended safe limit of 59 nGy/h.

Cognitive radio (CR) technology has been proposed to improve spectrum utilization by allowing cognitive radio users to opportunistically access under-utilized frequency band. The requirement of cognitive radio system is reliable detecting signals from licensed users to avoid harmful interference. However, due to the effects of the channel fading and shadowing, individual cognitive radio may not able to reliably detect the presence of a licensed user. In this paper, we propose a cooperative spectrum sensing scheme with double adaptive threshold and relaying users in order to improve sensing performance of both local sensing performance and global sensing performance in a CR network. In the proposed scheme, the detection threshold is changeable to adapt with the fluctuation of the received signal power in each local detector of cognitive user. In addition, the CR users with higher reliability act as a relaying user for the object of helping their neighbors to improve sensing performance. Finally, all the local observations will be sent to the fusion center to determine the global decision by using the Likelihood rule without any requirement on priori information of the licensed user.

In this article, we investigate the behaviour of a number of methods for estimating the co-integration rank in VAR systems characterized by heteroskedastic innovation processes. In particular, we compare the efficacy of the most widely used information criteria, such as Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) , with the commonly used sequential approach of Johansen [Likelihood-based Inference in Cointegrated Vector Autoregressive Models (1996)] based around the use of either asymptotic or wild bootstrap-based likelihood ratio type tests. Complementing recent work done for the latter in Cavaliere, Rahbek and Taylor [Econometric Reviews (2014) forthcoming], we establish the asymptotic properties of the procedures based on information criteria in the presence of heteroskedasticity (conditional or unconditional) of a quite general and unknown form. The relative finite-sample properties of the different methods are investigated by means of a Monte Carlo simulation study. For the simulation DGPs considered in the analysis, we find that the BIC-based procedure and the bootstrap sequential test procedure deliver the best overall performance in terms of their frequency of selecting the correct co-integration rank across different values of the co-integration rank, sample size, stationary dynamics and models of heteroskedasticity. Of these, the wild bootstrap procedure is perhaps the more reliable overall as it avoids a significant tendency seen in the BIC-based method to over-estimate the co-integration rank in relatively small sample sizes.

Abstract For effective modelling of flowshop scheduling problems, artificial neural networks (ANNs), due to their robustness, parallelism and predictive ability have been successfully used by researchers. These studies reveal that the ANNs trained with conventional back propagation (CBP) algorithm utilising the gradient descent method are commonly applied to model and solve flowshop scheduling problems. However, the existing scheduling literature has not explored the suitability of some improved neural network training algorithms, such as gradient descent with adaptive learning (GDAL), Boyden, Fletcher, Goldfarb and Shanno updated Quasi-Newton (UQ-N), and Levenberg-Marquardt (L-M) algorithms to solve the flowshop scheduling problem. In this article, we investigate the use of these training algorithms as competitive neural network learning tools to minimise makepsan in a flowshop. Based on training and testing measures, overall results from extensive computational experiments demonstrate that, in terms of the solution quality and computational effort required, the L-M algorithm performs the best followed by the UQ-N algorithm, GDAL algorithm, and the CBP algorithm. These computational results also reveal that the average percent deviation of the makespan from its best solution obtained by using the ANN trained with the L-M algorithm is the least among all examined approaches for the benchmark problem instances.

How cooperation and altruism among non-relatives can persist in the face of cheating remains a key puzzle in evolutionary biology. Although mechanisms such as direct and indirect reciprocity and limited movement have been put forward to explain such cooperation, they cannot explain cooperation among unfamiliar, highly mobile individuals. Here we show that cooperation may be evolutionarily stable if decisions taken to cooperate and to change group membership are both dependent on anonymous social experience (generalized reciprocity). We find that a win–stay, lose–shift rule (where shifting is either moving away from the group or changing tactics within the group after receiving defection) evolves in evolutionary simulations when group leaving is moderately costly (i.e. the current payoff to being alone is low, but still higher than that in a mutually defecting group, and new groups are rarely encountered). This leads to the establishment of widespread cooperation in the population. If the costs of group leaving are reduced, a similar group-leaving rule evolves in association with cooperation in pairs and exploitation of larger anonymous groups. We emphasize that mechanisms of assortment within populations are often behavioural decisions and should not be considered independently of the evolution of cooperation.

China's rapidly growing economy, population, and energy consumption are all threatening its future environmental sustainability. China faces many ecological challenges, and its reliance on coal is at the heart of most of the country's ecological troubles. Most of China's air pollution emissions come from the industrial and electricity sectors, and the human health costs of China's air pollution are very high. China is the largest global polluter, with more than 25 per cent of total global carbon dioxide (CO2) emissions, green development could help mitigate climate change and enhance global welfare. Over the past decades, the demand for energy sources has increased by 150% in China, which has made China among the most energy-consuming countries. Most of China's energy consumption comes from coal energy, which accounts for about 78% of all energy sources in China in 2011. China is one of the world's largest wind energy sources, according to data released by the World Wind Energy Association (WWEA), with about 34% of the world's wind energy sources. According to the road map implemented by the Chinese government by exploiting and generating wind energy sources and benefiting from the rapid economic development that China witnessed late, according to this plan by 2020, China is expected to produce about 250 gigawatts (GW). By 2030, production may reach 400 GW of electrical energy generated from wind energy, and by 2050, production may reach 1,000 GW.

Neonatal seizures are the most common overt manifestation of neurological dysfunction in the newborn. It may be the first and only manifestation of neurological dysfunction in variety of insults. The reported prevalence is approximately 1.5% and incidence is approximately 0.95–3.5 per 1,000 live births. 1-3 A seizure may arise from varying foci at different times. Not all clinical seizures correlate with electroencephalography (EEG) changes and not all seizure activity shown on EEG recordings are clinically apparent. 4 Since long EEG is an important tool to evaluate infant with symptoms refer to central nervous system. 5 The present study was aimed to use EEG not only as a method of assessing neonatal seizures but also for formulating prognosis for long term developmental outcome.

The strategy for tuberculosis (TB) control, endorsed by the World Health Organization (WHO)' is to administer short-course chemotherapy (SCC) under direct observation to at least all identified smearpositive TB cases. In many African countries, patients are hospitalized during the initial treatment phase, mainly to ensure drug compliance. However, intense hospital congestion as a result of increased TB cases has led to innovative ways to decentralize treatment into the c o m m ~ n i t y ~ , ~ . In some initiatives, patient's guardians and community care organizations directly observe the taking of anti-TB drugs. The use of nonhealth workers for drug supervision in Africa has not been widely tested, and leads to concerns about security of rifampicin which may be used for treatment of many non-TB conditions with the subsequent risk of developing drug resistance. SCC always includes rifampicin in the initial phase of treatment, usually in a combination tablet with isoniazid. Detection of isoniazid metabolites4 in urine is a well-tested method of monitoring compliance. This is relatively easy and cheap, but it is unlikely that African hospitals or health centres will ever regularly stock the chemical ingredients necessary for the

MORE THAN ANY OTHER work in the 1960s, Sheldon Wolin's "Political Theory as a Vocation" summed up the frustrations and hopes of the contemporary political theorist.' As a critique of "methodism" and its effects, the essay pointed toward the complacent political attitudes, trivial research, and enervating educational practices that were coming to dominate a good part of political inquiry. It effectively dispelled any lingering doubts that a "Panglossian twilight" was upon us. What excited the imagination, however, was not this sobering indictment, but rather Wolin's powerful summons to re-establish the public and pedagogic identity of the theorist. The vocation of political theory was said to offer a unique educational imperative, a distinctive mode of investigation, and a special kind of political engagement and knowledge, in contrast to those forms of inquiry in which the intellect was trammelled with "unpolitical theories shaped by the desire to explain certain forms of non-political phenomena" (1063). Fulfilling the intellectual and political promise of theory, particularly in its "epic" expressions, was left for subsequent demonstration. But Wolin hinted that to label ours "a world impervious to theory" (1081) was a poor plea for excuses. In an age in which "our whole world threatens to become anomalous," in which "facts are richer than theories," it was necessary for the "theoretical imagination to restate new possibilities" (1081-1082). "Political Theory as a Vocation" was meant to identify such necessity. A decade has now passed and one can appropriately ask what has become of the theoretical imagination and the promising vistas sketched for it? A comparison of "Political Theory as a Vocation" with Paul Kress's recent look at political theory and its discontents I American Political Science Review, 63 (Dec., 1969), 1062-1082.

Background Dietary antioxidants have been suggested to have protective role against chronic obstructive pulmonary disease (COPD), but few prospective studies examined this relationship. The prospective study was conducted to evaluate the effect of dietary antioxidants on COPD risk and lung function in the Korean population. Methods The data were collected from the community-based Korean Genome Epidemiology Study (KoGES) cohort. To diagnose COPD, forced expiratory volume (FEV1) and forced vital capacity (FVC) were measured by spirometry. The dietary intake of antioxidant vitamins was estimated from validated Food-Frequency Questionnaire. For the analysis, 325 COPD patients and 6,781 at risk subjects were selected from the cohort of 10,038 subjects. Multiple logistic regression models were used to examine the odds ratio (OR) after adjusting for age, sex, marital status, income, history of asthma, history of tuberculosis, and smoking. Results The risk of COPD was positively associated with aging, low education, low household income, lower body mass index, and cigarette smoking. The risk of COPD decreased with increase in the dietary vitamin C (ORQ1 vs Q5=0.66, Ptrend=0.03) and vitamin E (ORQ1 vs Q5=0.56, Ptrend=0.05) intake, predominantly, in men (Ptrend=0.01 and 0.05 for vitamins C and E, respectively). In addition, the lung function was significantly improved with increase in vitamins C (FEV1, P=0.04; FVC, P=0.03) and E (FEV1, P=0.03; FVC, P=0.04) intake. No statistically significant interactions were observed between smoking and vitamin C or E intake in relation to COPD risk among men. Conclusion Our results suggest the independent beneficial effect of antioxidants, particularly vitamins C and E, on COPD risk and lung function in men.

Abstract Chronic obstructive pulmonary disease (COPD) is a progressive disease characterized by airflow limitation resulting from emphysema and chronic bronchitis. Inhaled therapy is the major therapeutic approach for treating COPD. Multiple inhaler medications are available in the United States and are delivered by a variety of different devices: metered-dose inhalers, dry powdered inhalers, and nebulizers. Each inhaler device has unique requirements for use that must be correctly performed by the patient for successful drug delivery. Patients with COPD represent a medically diverse population, with each patient having distinct characteristics, such as lung function, comorbidities, cognitive functions, hand strength, and lifestyle. These characteristics impact the patient's ability to properly use specific inhaler devices and therefore affect adherence to therapy, therapeutic outcomes, and quality of life. It is estimated that between 28% to 68% of patients do not use metered-dose inhalers or dry powder inhalers correctly. Worsening symptoms or increased frequency of exacerbations may not always indicate disease progression but may indicate a patient's inability to use their inhaler device properly. This review discusses the patient- and device-specific factors to be considered when choosing an inhaled therapy, which will be concordant with the patient's medical needs, preferences, and lifestyle. The review also considers how the ideas underlying the patient-centered medical home model can be incorporated into the choice and use of inhaler device for a given patient with COPD to improve treatment outcomes.

We investigated the effect of lattice relaxation in the trivalent transition metal ions doped α-Al2O3 crystal (α-Al2O3: TM3+). The transition metal ions are Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+, and Co3+. The lattice relaxation effect was considered by comparing two different methods such as Shannon’s crystal radii methods and Cambridge Serial Total Energy Package (CASTEP) methods. In the Shannon’s crystal radii methods, the lattice relaxation effect was estimated as the ratio of the crystal radii of the substituted ion and the replaced ion. On the other hand, in the CASTEP method, the lattice relaxation effect was estimated by geometry optimization. The detail results show that in the case of Shannon’s crystal radii method, the lattice relaxation ratio was ca. 111.0 - 100.5%. Whereas in the case of CASTEP method, the lattice relaxation ratio was ca. 107.8 - 102.1%. However, the lattice relaxation ratio of α-Al2O3: Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+, and Co3+ is unique depends on the ion type.

PD-L1 expression assessed by immunohistochemical staining is used for the selection of immunotherapy in non-small cell lung cancer (NSCLC). Appropriate validation of PD-L1 expression in cytology specimens is important as cytology is often the only diagnostic material in NSCLC. In a previous study comprising two different cohorts of paired biopsies and cytological specimens, we found a fairly good cyto-histological correlation of PD-L1 expression in one, whereas only a moderate correlation was found in the other cohort. Therefore, that cohort with additional new cases was now further investigated for the impact of preanalytical factors on PD-L1 concordance in paired biopsies and cytological specimens. A total of 100 formalin-fixed paraffin-embedded cell blocks from 19 pleural effusions (PE), 17 bronchial brushes (BB), and 64 bronchoalveolar lavage (BAL) and concurrent matched biopsies from 80 bronchial biopsies and 20 transthoracic core biopsies from NSCLC patients were stained using the PD-L1 28-8 assay. Using the cutoffs ≥1%, ≥5%, ≥10%, and ≥50% positive tumour cells, the overall agreement between histology and cytology was 77–85% (κ 0.51–0.70) depending on the applied cutoff value. The concordance was better for BALs (κ 0.53–0.81) and BBs (κ 0.55–0.85) than for PEs (κ −0.16–0.48), while no difference was seen for different types of biopsies or histological tumour type. A high number of tumour cells (>500) in biopsies was associated with better concordance at the ≥50% cutoff. In conclusion, the study results suggest that PEs may be less suitable for evaluation of PD-L1 due to limited cyto-histological concordance, while a high amount of tumour cells in biopsies may be favourable when regarding cyto-histological PD-L1 concordance.

SUMMARY. 1. Predation on the mollusc genera Potamopyrgus, Bithynia, Valvata, Lymnaea, Physa, Planorbis and Pisidium by the leeches Glossiphonia complanata (L.) and Helobdella stagnalis (L.) was examined in five eutrophic lakes at monthly intervals over one year using a serological technique.
2. Feeding intensity varied seasonally, being lowest in winter and highest in summer. Small, medium and large leeches preyed to the same extent on the several mollusc genera; this was true for both leech species. Qualitatively, the diet of both glossiphoniids was similar throughout the year. Snail genera were consumed in proportion to their relative abundance in the field. Quantitatively, Glossiphonia preyed more heavily on snails than did Helobdella.
3. It is concluded that both leech species are opportunistic predators.

ABSTRACT Ethylenediamine Hydroxypropyl Tamarind Fruit Shell (EDAHP-TFS) was synthesized to remove Eriochrome Black T (EBT) from aqueous solutions. Maximum adsorption occurred at pH 2.0 and equilibrium time 2 h. Adsorption increased with increase in initial concentration and temperature. Adsorption kinetics obeyed the pseudo-second-order model and indicates a partial ion exchange, followed by the complexation mechanism. Lower E# (4.48 kJ/mol) represents film diffusion as the rate-limiting step. EBT removal followed the Sips isotherm model with a maximum adsorption capacity of 0.237 mmol/g at 30ºC. Isosteric heat of adsorption (ΔHi) decreased with increase in surface loading, indicating heterogeneous adsorption sites. Desorption studies were carried out and 96.4% recovery was achieved at pH 11.0. GRAPHICAL ABSTRACT

This special section of the Oral History Review had its origins in 2014 at the Berkshire Conference on the History of Women, held for the first time outside the United States in Toronto, Canada.The central conference theme—“Histories on the Edge/Histoires sur la brèche”—inspired numerous panels, performances, workshops, and public history tours that engaged feminist oral histories, including a roundtable discussion involving both of us, about the now twenty-six-year-old classic feminist oral history text, Women’s Words: The Feminist Practice of Oral History. We did not know what sort of audience to expect for our early morning roundtable, scheduled for the first day in a room some distance from the central conference buildings. But, to our delight, more than one hundred people arrived and shoehorned themselves into a space more suitable for thirty. Our discussion was lively; it highlighted the still-important insights of Women’s Words and other early feminist oral history scholarship, particularly the need to center the stories and experiences of women and other marginalized people in discussions of the past, and it raised difficult questions about feminist oral history. As an audience member, Lorraine Sutherland, one of our special section contributors, asked panelists to explain how her Ininiwuk storytelling traditions fit within feminist oral history. She, for one, did not see herself in most of the conversation about the field that day. For us, the remarkable presence of and engagement with feminist oral history on the Berkshire program were clear indications that across disciplines and generations, and among Indigenous and non-Indigenous artists, activists, and

Rateless code is applied to the wireless communication system, to solve the rate mismatch problem of fixed rate code due to the channel change. There is a good compromise of Accumulate Rateless Code (AR code) in rateless family on the decoding performance and complexity. But Log Likelihood Ratio-Belief Propagation (LLR-BP) decoding algorithm is based on the large consumption of time and resources. In this paper, to improve the decoding efficiency of AR code, we proposed an improved decoding algorithm based on LLR information value. By means of tracking the LLR information value of AR code in the process of decoding, and researching on the probability distribution of right and wrong decode symbol information value, we gave the best selection strategy of value_LLR threshold. The simulation analysis show that the proposed algorithm compared with traditional reset and not reset algorithms in decoding performance keeps almost the same, but it reduces 5.9% and 14.0% of the time consumption respectively.

Polarity of Tn10 insertion mutations in the Salmonella typhimurium ilvGEDA operon depends on both the location and the orientation of the Tn10 element. One orientation of Tn10 insertions in ilvG and ilvE permits low-level expression of the downstream ilvEDA and ilvDA genes, respectively. Our analysis of Salmonella ilv recombinant plasmids shows that this residual ilv expression must result from Tn10-directed transcription and does not reflect the presence of internal promoters in the ilvGEDA operon, as was previously suggested. The opposite orientation of Tn10 insertion in ilvE prevents ilvDA expression, indicating that only one end of Tn10 is normally active in transcribing adjacent genes. Both orientations of Tn10 insertion in ilvD exert absolute polarity on ilvA expression. Expression of ilvA is known to be dependent on effective translation of ilvD, perhaps reflecting the lack of a ribosome binding site proximal to the ilvA sequence. Therefore, recognition of the ability of Tn10 to promote transcription of contiguous genes in the ilvGEDA operon apparently requires the presence of associated ribosome binding sites.

Ethanol at an average blood concentration of 1 mg. per milliliter enhanced the immediate (first-phase) and prolonged (second-phase) insulin response to an intravenous glucose load in nonfasting normal human subjects. Simultaneously, the glucose disposal rate was increased and the postglucose hypoglycemia was accentuated, resulting in definite hypoglycemic symptoms in some individuals. Oral glucose tolerance was not changed by ethanol administration, but the thirty-minute blood glucose and plasma insulin values were increased, suggesting that alcohol might accelerate the absorption of glucose from the gut. Ethanol given orally during evening hours (1.5 gm. per kilogram) caused a nocturnal hyperinsulinemia and a decrease of blood glucose, but not an actual hypoglycemia. Oral glucose tolerance and plasma insulin response tested the next morning, when ethanol had disappeared from the blood, were not influenced by drinking the previous evening. The K-value of intravenous glucose was increased at this time, however. When alcohol was administered for one week at a dose corresponding to 25 per cent of daily calories and substituting for fat, both the oral and intravenous glucose tolerances were impaired in each subject but the insulin response remained unchaged. In obese nondiabetic subjects, ethanol did not potentiate the early insulin response to intravenous glucose but it increased the second phase of insulin secretion in response to sustained hyperglycemia. In contrast to conditions in nonobese subjects, the glucose disposal rate was not incresed and postglucose hypoglycemia was not accentuated by ethanol in overweight subjects. In insulin-deficient diabetic patients the absent early insulin response could not be restored by ethanol, and the late component of insulin release was little increased by alcohol infusion. Ethanol did not improve the glucose utilization of diabetic patients.

O uso da dapsona e frequentemente associado a efeitos adversos hematologicos, como a metemoglobinemia e anemia hemolitica, ambos relacionados com a N-hidroxilacao mediada pelo sistema P450. O objetivo do estudo foi avaliar a influencia da suplementacao de L-arginina, um precursor da sintese de oxido nitrico, administrado em regime de dose unica ou multipla na metemoglobinemia induzida pela dapsona. Ratos machos Wistar foram tratados com L-arginina (po, gavagem) em dose unica ou multipla de 5, 15, 30, 60 e 180 mg/kg 2 horas antes da administracao de dapsona (40 mg/kg, ip). O efeito do L-NAME, um inibidor de oxido nitrico sintase (NOS), foi avaliado atraves do tratamento com doses multiplas de 30 mg/kg. Amostras de sangue foram coletadas duas horas apos a administracao de dapsona. A concentracao de metemoglobina eritrocitaria foi analisada por espectrofotometria. Os resultados mostraram que a suplementacao em dose multipla de 5 e 15 mg/kg de L-arginina reduziu os niveis de metemoglobina induzida pela dapsona. Este efeito e mediado pela formacao de oxido nitrico, uma vez que a reducao nos niveis de metemoglobina pela L-arginina e bloqueada pela administracao simultânea de L-NAME, um inibidor da oxido nitrico sintase.

Au redistribution layers 10 to 100 μm wide were fabricated on heterogeneously integrated advanced flexible hybrid electronics (FHE) substrates formed by a die-first approach based on fan-out wafer-level packaging. The formed Au metal wiring was meticulously studied for locally induced mechanical stress upon bending (bending radius, BR 20 mm) using Laue microdiffraction (LμD) with synchrotron radiation. It was inferred from the LμD data that upon bending the FHE substrate up to the BR of 20 mm, the Au metal wiring (10 mm long, 100 μm wide, and 500 nm thick) experienced mechanical bending stress amounting to 250 ∼ 300 MPa. The stress values obtained from the LμD studies were close to the stress value of 350 MPa obtained by simulation.

Given a nonatomic scalar measure ,u, there is a vector valued, ,u-continuous measure of finite variation which has no derivative with respect to ,u, but which has the property that the closure of its range is compact and convex. In this note we give an example of a vector measure which answers a question raised in [5]. Further, the example can be used to gain some information about certain Banach spaces with the Radon-Nikodym property. Measure theoretic terminology is that of [5]. The Banach space (under supremum norm) of all real sequences which converge to zero is written c0. An element of c0 will be denoted by a doubly indexed sequence (an, ) with n > 1 and 2' 1 and 2n?i 0, choose m?>1 so that 2-m,4(S)<s. Again using the fact that Iu has no atoms there are measurable sets BicAm i, 2m<i<2`n+-, satisfying iu(Bi)=am,i. Then 11 p(B)-(an,i)ll <e, where B= U2mri<2m+i Bi. To see that 9v has no derivative with respect to Iu, we suppose the contrary. Letf: S--co be a derivative of 9v and write (en, i) for the unit vectors Received by the editors June 14, 1971.

Four sulfur-oxidising bacteria were selected among 427 bacterial isolates from calcareous sandy soils in the United Arab Emirates (UAE). These isolates were selected based on their strong ability to oxidise elemental sulfur (S°) in vitro and were identified as Paracoccus versutus CBS 114155, Paracoccus pantotrophus CBS 114154, and 2 strains as Rhizobium spp. NCCB 100053 and NCCB 100054. This is the first published report of a Rhizobium species capable of S° oxidation and also the first record of sulfur-oxidising bacteria from UAE soils. These isolates were tested in a greenhouse in the presence and absence of S° to study their effects on maize growth. Best growth was observed in the treatment with P. versutus application combined with S°, which significantly reduced soil pH, increased soil SO4 level and the uptake of N, S, Fe, Mn, and Zn in maize roots and shoots. The P and Cu uptake in the shoots of maize plants was not significant compared with the treatment that received the application of S° alone. There was no response in plant growth to treatments that included the application of S° combined with P. pantotrophus or Rhizobium strain NCCB 100053 compared with the treatment that received the application of S° alone. There was significant growth inhibition of maize plants in the treatment receiving Rhizobium strain NCCB 100054 with or without the application of S° compared with the treatment that included the application of S° alone. This growth inhibition was associated with a significant decrease in the levels of N, P, S, Fe, Mn, Zn, and Cu in roots and shoots in the absence of S°. Rhizobium strain NCCB 100054 applied with S° significantly decreased the levels of N, S, and Fe in the roots and the levels of N, P, S, Fe, Mn, and Cu in the shoots of maize, with no significant differences in the levels of P and Mn in the roots and in the levels of Zn in the shoots, compared with the treatment with S° alone. These results indicate that the treatment P. versutus combined with S° can be effective as a soil conditioner for horticultural production in calcareous sandy soils.

The purpose of this quasi-experimental study was to understand the implementation of Project Citizen in Social Studies, to evaluate its effects upon the civic development of junior high school students, and to document the teacher's and students' perceptions of Project Citizen. Two classes of 8(上标 th) graders, one experimental and one comparison, participated in this study. The results showed that students participating in Project Citizen significantly outperformed students in the comparison group in civic dispositions and skills. Additionally, qualitative analyses of the interview revealed that the participating teacher and students responded positively toward the Project Citizen program. The teacher also expressed interest in implementing the program again in her classes. It also suggested, however, that unequal distribution of responsibility, time constraints, and pressure from the Basic Competence Test for Junior High School Students (BC Test), among other factors, pose significant challenges to implementing/learning Project Citizen in the junior high school context.

The classical prompt loss of fast ions produced by minority ion cyclotron resonance heating (ICRH) is studied by a guiding center orbit following code in the Experimental Advanced Superconducting Tokamak (EAST). It is found that the loss of fast ions produced by ICRH mainly appears in both ends of the resonance layer, while the loss of fast ions in the middle resonance layer is very small. The dominant fast loss comes from trapped ions, rather than from passing ions. Controlling the location of resonance layer at the plasma core may be more beneficial to the EAST tokamak ion cyclotron resonance heating. In addition, the loss distribution of fast ions is studied. The results show that the fast ions are mainly lost near the midplane in poloidal direction while almost uniformly in toroidal direction. Moreover, we investigate the dependence of fast ions loss on the ICRH power. The simulation results show that the loss fraction of fast ions in both ends of the resonance region increases with the ICRF power, but barely affects the loss of fast ions in the middle region.

This work determined what effect stiffness in the direction normal to the plane of contact between surfaces in sliding contact had on the phenomenon of stick-slip. The results showed that the amplitude if stick-slip vibrations could be reduced by increasing the normal stiffness with contacting surfaces of mild steel. It was also observed that with the above mentioned surfaces some wear had to take place before stick-slip would occur. This was attributed to the initial presence of oxide on the surfaces. Presented at the 24th ASLE Annual Meeting in Philadelphia, May 5–9, 1969.

Clay has its widespread applications in pharmaceuticals from ancient world to modern era. It is one of the excellent excipients present in the commercially available pharmaceuticals. Its use in many of dosage forms viz. in suspension, emulsion, ointments, gels, tablet and as drug delivery carrier as suspending agent, emulsifying agent, stiffening agent, binder, diluent, opacifier, and as release retardant have been explored in many studies. Variety of minerals is used as both excipient and as an active ingredient; among that kaolinite, talc, and gypsum are important. Their inertness, low toxicity, versatile physiochemical properties and cost effectiveness has increased its usage in pharma industries. Many minerals have its own pharmacological action as antacid, anti-bacterial, anti-emetic, antidiarrheal agent and as skin protectant etc. Their unique structure which helps them to absorb material onto their layered sheets has opened a wide variety of applications in drug delivery. The understanding of surface chemistry and particle size distribution of clay minerals has led the pharmaceutical field in many directions and future perspectives.

Forekomsten av helseplager var stor i pasientgruppen
En betydelig andel av pasientene hadde udiagnostiserte sykdomstilstander som kan behandles
Elleve prosent av de undersøkte pasientene ble anbefalt å skifte ut fyllinger på grunn av allergi eller kontaktlesjon. Tretten prosent fikk anbefaling om å unngå stoffer ved fremtidig behandling på grunn av påvist allergi
Av de pasientene som hadde skiftet ut alle sine amalgamfyllinger, oppga 42 % at de langsiktige virkningene var «betydelig bedring» eller «helt bra, symptomfri», mens 13 % oppga at de var blitt verre
Blant pasientene som hadde skiftet fyllinger, var det en større andel som oppga bedring av helsen enn blant pasienter som ikke hadde skiftet fyllinger
De pasientene som hadde skiftet ut tannmaterialer etter anbefaling fra Bivirkningsgruppen, hadde en signifikant minsket intensitet av intraorale plager

Recently there has been renewed interest in using field ionization as a method of detecting neutral atomic/molecular species. However, the current–voltage characteristic of a field ionization detector is very difficult to calculate from first principles, making comparison, characterization and monitoring difficult. Here we present a semi-empirical theory designed for macroscopic characterization and comparison of field ionization devices via the current–voltage curve in a similar fashion to the familiar Fowler–Nordheim analysis for field emission devices. The resulting model allows us to monitor the changes in a single field ionization detector, or, more importantly, to make quantitative comparisons between detectors. We demonstrate that this new model accurately reproduces the characteristic field ionization current versus voltage profiles in both low and high field regimes.

A prospective, randomized study was designed to compare the outcome of inferior pedicle/Wise pattern reduction (group I) with medial pedicle/vertical pattern reduction (group II) in moderate resections averaging 500 g per breast. There were 105 women in group I and 103 women in group II. All surgical procedures were performed by the same plastic surgeon. Patient information recorded included age, body mass index, type of surgery, weight of specimen, need for surgical revision, and complications. Six months postoperatively the patients were asked to complete a questionnaire, which rated their satisfaction with the surgical outcome. The questionnaire used a 10-point response format ranging from very disappointed (score of 1) to very pleased (score of 10). The results demonstrated that there was no significant difference between the groups in age (31 ± 12 versus 29 ± 13 years), body mass index (26 ± 4 versus 27 ± 5), and amount of tissue excised (553 ± 203 g versus 548 ± 205 g). Group I required no surgical revisions, but in group II revisions for dog-ears were required in 11 percent. The rate of other complications was similar in both groups. Patients’ evaluations of breast size, shape, symmetry, nipple sensation, symptom relief, ease of brassiere/clothing fitting, and overall satisfaction were not significantly different. The vertical mammaplasty was ranked significantly (p < 0.05) higher by patients in regard to scars (6 ± 2 versus 3 ± 3) and overall aesthetic results (8 ± 1 versus 6 ± 3). In the management of moderate macromastia, this study indicates that patients who have a vertical reduction are less disappointed with the scars but require a significantly higher rate of surgical revisions compared with patients who have a Wise pattern reduction.

The soybean (Glycine max (L.) Merr.) is an economically important leguminous crop for feed, oil, and soyfood products. It contains about 40% protein and 20% oil in the seed and, in the international trade markets, is ranked number one in oil production (48%) among the major oil seed crops. Despite its economic importance, the genetic base of soybean cultivars is extremely narrow. The indigenous cultivars and landraces in East Asia are on the verge of extinction, because farmers are now growing high yielding soybean cultivars. The exotic germplasm, enriched with genes for abiotic and biotic stresses, has not been fully exploited by soybean breeders. Mutation breeding has improved the fatty acids of the soybeans and has produced soybeans tolerant to herbicides. By using recombinant DNA technology, Monsanto has produced stable glyphosate tolerant soybean lines known as 'Round Up Ready' soybean. DuPont is producing transgenic soybean lines with improved fatty acids content. The feasibility of developing hybri...

The spatial separation of reduction and oxidation reaction sites on the different facets of a semiconductor is an ideal and promising route for overall photocatalytic water splitting due to efficient charge carrier separation. Rutile TiO2 has separate oxidation and reduction crystal facets and can be used to achieve direct splitting of pure water under ultraviolet (UV) light irradiation. In order to improve the rate of water oxidation reaction, the ratio of different crystal facets of rutile should be regulated controllably. However, the preparation of rutile TiO2 architecture has been limited by the availability of synthetic techniques. In this study, rutile TiO2 nanorods with various aspect ratios were accurately prepared in the presence of Cl- anions and H+ cations, which were found to play a crucial role in forming the morphology of rutile TiO2 nanorods. In addition, the mechanism involving the growth of rutile TiO2 nanorods with different aspect ratios is proposed. Rutile TiO2 nanorods with a high proportion of oxidative (111) facets provided higher overall water splitting reactivity.

Background The increase in incidence of multidrug-resistant (MDR) organisms, especially gram-negative bacteria, in healthcare facilities is a serious cause of concern worldwide. This study was done at King Abdulaziz Medical City, Jeddah, a tertiary care hospital. The World Health Organization has published a priority pathogens list of antibiotic-resistant bacteria. The priority pathogens have been categorized into three major priorities (i.e., critical, high, and medium). The critical priority pathogens include common gram-negative bacteria (GNB) such as carbapenem-resistant Acinetobacter baumannii, carbapenem-resistant Pseudomonas aeruginosa, and carbapenem-resistant and third-generation cephalosporin-resistant Enterobacteriaceae such as Klebsiella pneumoniae and Escherichia coli. The current study identified risk factors for the acquisition of these MDR gram-negative critical priority pathogens in King Abdulaziz Medical City, Jeddah, to inform strategies for their containment. Methods A case-control study was carried out from January to April 2015, in which 100 patients with healthcare-associated infections (infections arising 48 hours after admission) caused by MDR GNB were compared with two control groups, i.e., 100 patients with healthcare-associated infections caused by non-MDR GNB (not meeting the criteria of MDR) and 100 patients without infection caused by GNB. MDR bacteria were defined as bacteria that were non-susceptible to at least one antibiotic in three or more classes of antibiotics. Data were analyzed using descriptive statistics (frequency and percentage of categorical variables). Multivariate regression analysis was undertaken to identify significant predictors of MDR GNB. Odds ratios (ORs) with 95% CIs were calculated and the level of significance was determined as p Results A total of 388 organisms were isolated during the study period from 332 patients. 56 (14%) patients were infected with more than one organism. Antibiotic therapy (OR 5.50, 95% CI 2.19–13.84; OR 3.98, 95% CI 1.68–9.44), stay in intensive care unit (OR 11.11, 95% CI 4.58–26.93; OR 8.60, 95% CI 3.28–22.57), and having indwelling medical devices (OR 3.02, 95% CI 1.45–6.33; OR 2.43, 95% CI 1.11–5.33) were the significant risk factors in patients infected with MDR GNB compared with each of the other two control groups, respectively. Conclusion The risk factors identified in our study provide guidance for healthcare workers for the prevention and containment of MDR GNB with special emphasis on effective implementation of an antimicrobial stewardship program and enhancing infection control practices in intensive care units.

The publication of the Shirburn Ballads has brought us another proof of the popularity of this song. The form in which it occurs in that collection (No. LIX) calls for no special remark: with here and there a scribal difference, it is the same as No. XII of my paper (Modern Philology, IV, 3), that is to say the version of the Roxburgh Ballads. The song is headed by an editor's note, which winds up as follows: "The verses are found also in a Bodleian MS, MS Rawlinson poet. 112, fol. 9, and are there attributed to 'E. of E.?' Robert Devereux, second earl of Essex." The summary catalogue of this MS says: "foll. 9, 10, 11, 'Verses or English poemes written by the Lo: the E[arl] of E[ssex],' beginning 'There was a time when seely bees could speake,' and (on 'The fickle state of our uncertayn life') 'What if a day.'" It would seem that Mr. Clark has relied on this remark. At least the librarian informs me that "the poem is on f. 10v and f. 11; is not headed by any attribution, and that the verses attributed to the E. of E. are on f. 9 and in a different hand." The earl of Essex lived from 1567-1601 so that, even if the note also referred to "What if a Day," "written by the E. of E." can only mean "copied by the E. of E.," or else must be considered as a faulty statement, as the same reason that prevents us from considering Campion as the author also prevents us from considering the earl of Essex as such. In itself the version is a very interesting one. It will be seen at a glance that it differs from all others in counting four stanzas; all other versions have two, three, five or more. Stanza i belongs to the group beginning " What if a day, a month or a year," and to that having in the fifth line "Fortune, honour, beauty, youth." It agrees closely with the version in Farr's Select Poetry (No. XI of my paper), as does stanza ii. So far there is nothing striking; Stanza iii, however, also agrees with the version in Farr's Select Poetry, and occurs nowhere else, while

Abstract The Sornette–Ide differential equation of herding and rational trader behaviour together with very small random noise is shown to lead to crashes or bubbles where the price change goes to infinity after an unpredictable time. About 100 time steps before this singularity, a few predictable roughly log-periodic oscillations are seen. A statistical analysis of DJ, S&P and Sofix (the share index for Bulgaria) shows higher fluctuations in the Sofix. This is consistent with the assumption that higher noise levels lead to shorter times between crashes. The higher level of fluctuations for the Sofix is consistent with Maslov's results comparing share indices for emerging and established markets (Maslov 2001 Physica A 301 397) * Paper presented at Applications of Physics in Financial Analysis (APFA) 3, 5–7 December 2001, Museum of London, UK.

The North Sumatra Basin is well known as a highly overpressured basin in Western Indonesia. Most of the sedimentary basins in western Indonesia, including the North Sumatra Basin, have similar histories of basin development. The basement of Paleozoic and Mesozoic sedimentary and metamorphic rocks is overlain by a syn-rift sequence, then a post-rift sequence associated with basin subsidence, and finally a sequence of shallow marine‐fluvial deposits. Overpressured strata are commonly encountered in the post-rift sequence because it is dominated by fine-grained sediments of low permeability. In the North Sumatra Basin, the post-rift sequence comprises the Baong

In the present paper we analyse the contributions of nitro group movements in 2-chloro-nitrobenzene to the nuclear quadrupole resonance (NQR) parameters of the chlorine nucleus in the molecule. We found two contributions to the spin–lattice relaxation time (T1) and the NQR frequency (νQ) due to the onset of nitro group movements in the molecule. One of these contributions is the well-known semirotation of the nitro group around the N–C axis. The other one is attributed to some tilting or tipping of the nitro plane away from the benzene ring introducing some dynamic orientational disorder of this group in the crystal only observed as a contribution from the temperature dependence of T1 and νQ. Its activation energy is similar to that of the nitro group reorientation (21.9 and 23.6 kJ mol−1 for the two processes) and may arise from competing crystalline and steric chlorine nucleus effects. The present investigation shows that in chloronitrobenzenes the NO2 group dynamic orientational disorder can produce modulation effects on the chlorine T1 which are large enough to be observed by means of the NQR.

Visual neglect has been frequently described in a horizontal direction. Altitudinal neglect, however, has rarely been described and has been associated with bilateral lesions in the parieto-occipital or temporo-occipital region. The following case report presents a patient with marked altitudinal neglect of the inferior space which was elicited using a line bisection test. The previously healthy patient had well-defined lesions solely in the occipital cortex following an embolic infarction. The present case report underlines the possibility that bioccipital lesions themselves can be responsible for altitudinal neglect.

We report thirty‐three patients with alternating skew deviation on lateral gaze. The right eye was hypertropic in right gaze, and the left eye was hypertropic in left gaze. Most patients had associated downbeat nystagmus and ataxia and were diagnosed as having lesions of the cerebellar pathways or the cervicomedullary junction. This contrasts with a previous report in which alternating skew was seen mainly in lesions of the midbrain pretectum.

made up of iris periphery, iris collarette and freckles. Iris periphery is the outermost part of the iris. Iris collarette is the band of colour adjacent to the pupil. Stromal melanocytes are most abundant near the collarette. We identified blue–grey periphery, with a blue collarette and absence of freckles as the iris pattern most associated with skin cancer in our population. Green iris periphery was found in 11.2% (n = 19) and was not significantly associated with skin cancer. Green eyes are reported to be associated with higher risk of uveal melanoma compared to brown. Our study is the first study investigating iris pattern and skin cancer risk in Northern European population. It shows that a blue iris collarette is significantly associated with skin cancer. This technique of iris pattern recognition may be used to more precisely identify high-risk patients who would benefit from skin cancer screening. It is also applicable to virtual clinics in the current COVID-19 pandemic where a simple digital image of the iris could aid in patient risk stratification for skin cancer.

This article focuses on the herd behavior of the SSE STAR Market between July 22, 2019, and April 31, 2020, to analyze the dynamic evolution of herd behavior in the SSE STAR market under the characteristics of high liquidity and volatility based on high-frequency daily data, as a way to explain the mystery of high volatility and liquidity of the SSE STAR market. The results show that the SSE STAR market has significant herd behavior in the sample period, and has typical high asymmetry and volatility characteristics, but does not have high liquidity characteristics.

A 7-year-old castrated male Rottweiler was evaluated for an 18-month history of bilateral hind limb lameness, signs of pain on rising, and mild ataxia. A gas-filled lumbosacral disk space (vacuum disk phenomenon) was revealed by use of computed tomography. Additional smaller gas bubbles were in the periphery of the disk and between the degenerated L5-L6 dorsal articular facets (vacuum facet phenomenon). Vacuum disk and facet phenomena have been described in humans with degenerative disk and vertebral articular facet joint disease; gas attracted from surrounding tissues accumulates within clefts of the degenerated disk or in unstable facet joints. Vacuum disk phenomenon has been reported in dogs and indicates degenerative disk disease. The phenomenon is more commonly observed by use of computed tomography, compared with conventional radiography, and can be elicited by hyperextension of the vertebral column.

We analyze an oligopolistic competition with differentiated products and qualities. The quality of a product is not known to consumers. Each firm can make an imperfect disclosure of its product quality before engaging in price-signaling competition. There are two regimes for separating equilibrium in our model depending on the parameters. Our analysis reveals that, in one of the separating regimes, price signaling leads to intense price competition between the firms under which not only the high-quality firm but also the low-quality firm chooses to disclose its product quality to soften the price competition.

This paper investigates the flexural performance of a sandwich panel made up of ultra high strength concrete (UHSC) as top and bottom skin and cold formed steel as sandwich. A novel sandwich panel has been designed such a way that bottom skin of UHSC is of precast in nature and top skin of UHSC is cast-insitu and cold formed steel (profiled sheet) as sandwich. The connection between top skin of UHSC and cold formed steel is made with self tapping screws. Flexural performance of UHSC sandwich panel has been tested under flexural loading and it is found that the post peak response of the panel is significant in terms of more energy absorption. It is observed that the final failure of the specimen is occurred by forming a dominant crack on the bottom face of the skin apart formation of many multiple cracks with increase of load. Numerical investigations have been carried out by simulating the experimental conditions and found that the response obtained through simulation is in good agreement with the corresponding experimental values. From the studies, it can be concluded that UHSC steel sandwich panels can be employed for structural and non structural applications.

BackgroundAdvances in analytical methods of the epicardial electrical potentials allowed us to demonstrate spatial distributions of local recovery. Because local recovery will be reflected in events on body surface ECG mapping, abnormalities in recovery sequence that may be responsible for the origin of negative T waves can be detected from body surface potentials. Methods and ResultsEighty-seven unipolar ECGs were recorded simultaneously from the entire thorax in patients having negative T waves on left anterior precordial leads and in normal subjects. These included 40 patients with anterior myocardial infarction (MI), 21 patients with left ventricular hypertrophy (LVH), and 44 male volunteers. We measured T., time, defined as the instant of maximal first derivative of the T wave as the index of local recovery (Wyatt's method). Parameters related to T wave potentials were positive T wave amplitude, negative T wave amplitude, and T integral. Significant correlations were observed between the TMAX time and each of the T wave potentials. The T wave potentials were dependent on TMAX times. In the anterior MI, the late Tma times were located on the upper left anterior chest and early T.a. times on the lower right lateral chest. In the LVH, the area showing a delayed recovery was displaced in a left downward direction compared with anterior MI. ConclusionsBody surface TMAX time distributions clearly separate two negative T wave groups, i.e., anterior MI and LVH. Appearance of the negative T waves correlates well with the presence of the area with delayed TMAX time on the spatial distribution.

The parameter-free reconstruction of the surface-mass density of clusters of galaxies is one of the principal applications of weak gravitational lensing. From the observable ellipticities of images of background galaxies, the tidal gravitational field (shear) of the mass distribution is estimated, and the corresponding surface mass density is constructed. The noise of the resulting mass map is investigated here, generalizing previous work which included mainly the noise due to the intrinsic galaxy ellipticities. Whereas this dominates the noise budget if the lens is very weak, other sources of noise become important, or even dominant, for the medium-strong lensing regime close to the center of clusters. In particular, shot noise due to a Poisson distribution of galaxy images, and increased shot noise owing to the correlation of galaxies in angular position and redshift, can yield significantly larger levels of noise than that from the intrinsic ellipticities only. We estimate the contributions from these various effects for two widely used smoothing operations, showing that one of them effectively removes the Poisson and the correlation noises related to angular positions of galaxies. Noise sources due to the spread in redshift of galaxies are still present in the optimized estimator and are shown to be relevant in many cases. We show how (even approximate) redshift information can be profitably used to reduce the noise in the mass map. The dependence of the various noise terms on the relevant parameters (lens redshift, strength, smoothing length, redshift distribution of background galaxies) are explicitly calculated and simple estimates are provided.

Apparent resistivity in the frequency range of 100-1000 kHz and soil electromagnetic emission parameters in the frequency range of 1-300 kHz are proposed to be used as criteria for assessing the influence of climatic factors on the condition of permafrost foundations. The addition of traditional measurements of soils temperature by measurements of their apparent resistivity raises information maintenance of monitoring. The joint consideration of effective resistance and temperatures gives more complete representation about changes of a soils condition, climatic factors, occurring as result of influence. By monitoring apparent resistivities, it is possible not only to assess the degree of soil freezing, but also to take into account changes in volumetric ice content (moisture content) and other physical properties. Apparent resistivity can also be used to detect and estimate the influence of such climatic factors, as rainfall and snow depth. The phenomenon of electromagnetic emission in frozen ground is shown to be an indicator of on-going processes of thawing or freezing. Electromagnetic emission parameters are thus useful for assessing intensity and duration of soil thawing and freezing.

Curcumin is a compound extracted from the Curcuma longa L, which possesses a wide range of pharmacological effects. However, few studies have collected scientific evidence on its dual effect on angiogenesis. The present review gathered the fragmented information available in the literature to discuss the dual effect and possible mechanisms of curcumin on angiogenesis. Available information concerning the effect of curcumin on angiogenesis is compiled from scientific databases, including PubMed and Web of Science using the key term (curcumin and angiogenesis). The results were reviewed to identify relevant articles. Related literature demonstrated that curcumin has antiangiogenesis effect via regulating multiple factors, including proangiogenesis factor VEGF, MMPs, and FGF, both in vivo and in vitro, and could promote angiogenesis under certain circumstances via these factors. This paper provided a short review on bidirectional action of curcumin, which should be useful for further study and application of this compound that require further studies.

Abstract In the years 1963–1979, altogether 176 Swedish earthquakes have been detected and located, mainly from records from the Swedish Seismograph Station Network (SSSN). The earthquakes have occurred within a belt from the southwestern to the northeastern part of the country and in northern Lapland. Corresponding local magnitudes are not greater than 4. b-values of the magnitude-frequency relation are 0.7 and 1.5 for magnitude intervals 2.2–3.0 and 3.0–3.9, respectively. The strain energy release has been rather regular during most of the time. The apparent increase of small-size shocks in recent years is due to improved instrumental facilities and not to a real increase of seismicity. The presented data can be used as a base for seismotectonic and seismodynamic studies of the Swedish bedrock.

To understand the reality of gambling disorder caused by playing pachinko/pachislot, a national pachinko/pachislot survey was conducted. Based on the survey result, we examined the appearance ratio and the characteristics of individuals with a suspected pachinko-pachislot playing disorder. The analysis result indicated that approximately 0.4% of survey respondents were suspected to have the disorder. This appearance ratio was comparable to the prevalence of gambling disorder in the general population. Those who had a suspected disorder were likely to be divorced, and have no savings. Meanwhile, no distinctive characteristics were found in their gender, annual household income, or the highest educational attainment.

By redefining villeinage as applicable only to those of English heritage, Somerset v. Stewart inadvertently expanded Englishness to encompass English Jews, who had been associated with villeinage both in the medieval and early modern periods. The sudden cessation of legal and political references to Jewish villeinage post- Somerset constitutes a reframing of Jewish history, with the goal of reestablishing the boundary between Englishness and Jewishness. To fully understand Somerset’s contribution to the making of Englishness, we must, therefore, look beyond the case’s impact on racial slavery and consider the role the case played in legally and politically redefining English Jews as fundamentally non-English.

Gallium phosphide bismide (GaP1-xBix) epilayers with bismuth fractions from 0.9% to 3.2%, as calculated from lattice parameter measurements, were studied with Rutherford backscattering spectrometry (RBS) to directly measure bismuth incorporation. The total bismuth fractions found by RBS were higher than expected from the lattice parameter calculations. Furthermore, in one analyzed sample grown by molecular beam epitaxy at 300 °C, 55% of incorporated bismuth was found to occupy interstitial sites. We discuss implications of this high interstitial incorporation fraction and its possible relationship to x-ray diffraction and photoluminescence measurements of GaP0.99Bi0.01.

From the conquest of the Ming dynasty in 1644 by the Manchurians through the literary inquisitions of the eighteenth century, seemingly innocuous paintings of peony flowers kept alive a discourse of Ming loyalism among Chinese artists and poets. While the peony’s appearance in poetic imagery was deemed seditious by the Qianlong emperor (r. 1736–1795), paintings by Yun Shouping, Shitao, Hua Yan, and Jin Nong, among many others, endured a century and a half of censorship, all the while contributing to portrayals of the flower in court imagery. This study examines peony paintings by several artists active in the Jiangnan region to consider how their works demonstrated traces of dissent or used loyalist imagery to deepen social ties. It reveals how these garden subjects were made powerfully subversive after centuries of dormant conventionality, seen merely as auspicious symbols until the Qing dynasty. Their multivalent imagery allowed them to exist in multiple, conflicted contexts: north and south, literati and academic, private and public, and, in the ultimate coup, amid both loyalists and the Manchu court.

We formulate a free probabilistic analog of the Wasserstein manifold on $\mathbb{R}^d$ (the formal Riemannian manifold of smooth probability densities on $\mathbb{R}^d$), and we use it to study smooth non-commutative transport of measure. The points of the free Wasserstein manifold $\mathscr{W}(\mathbb{R}^{*d})$ are smooth tracial non-commutative functions $V$ with quadratic growth at $\infty$, which correspond to minus the log-density in the classical setting. The space of smooth tracial non-commutative functions used here is a new one whose definition and basic properties we develop in the paper; they are scalar-valued functions of self-adjoint $d$-tuples from arbitrary tracial von Neumann algebras that can be approximated by trace polynomials. The space of non-commutative diffeomorphisms $\mathscr{D}(\mathbb{R}^{*d})$ acts on $\mathscr{W}(\mathbb{R}^{*d})$ by transport, and the basic relationship between tangent vectors for $\mathscr{D}(\mathbb{R}^{*d})$ and tangent vectors for $\mathscr{W}(\mathbb{R}^{*d})$ is described using the Laplacian $L_V$ associated to $V$ and its pseudo-inverse $\Psi_V$ (when defined). Following similar arguments to arXiv:1204.2182, arXiv:1701.00132, and arXiv:1906.10051 in the new setting, we give a rigorous proof for the existence of smooth transport along any path $t \mapsto V_t$ when $V$ is sufficiently close $(1/2) \sum_j \operatorname{tr}(x_j^2)$, as well as smooth triangular transport.

ABSTRACT We tested the activities of rifampin (RIF) and rifaximin (RFX) against 180 Clostridium difficile clinical isolates selected from Canadian and Italian culture collections. MICs were determined by CLSI agar dilution for both drugs and by Etest for RIF. Sixteen of 85 Italian isolates (18.8%) showed high-level resistance to both rifamycins (MICs, >16 μg/ml), compared to 2 of 95 (2.1%) Canadian isolates. Two new rpoB mutations were identified in rifamycin-resistant isolates. RIF susceptibility by Etest correlated completely with susceptibility to both rifamycins determined by agar dilution.

OBJECTIVE
To present the validation of a theoretical model through conversation circles in a qualitative research guided by the Grounded Theory.
METHOD
Study carried out from a thesis developed in a reference hospital in the south region of Brazil. Two conversation circles happened, with participation of representatives of the "Training Prism", in the months of October and November, 2016.
RESULTS
The conversation circle enabled an in depth dialogic approach of the subject of research, broadening the vision on the phenomenon and on the research. The circle also mobilized thinking as it highlighted the subjectivity of individuals, expanding the group's ability of understanding and assisting in the validation process of a theoretical model.
CONCLUSION
The conversation circle emerges as a powerful strategy for the development of qualitative research in nursing, more specifically in the validation step of the Grounded Theory.

Femtosecond laser-produced plasmas are bright ultrafast line x-ray sources potentially suitable for different applications including material science and biology. The conversion efficiency of the laser energy incident onto a solid target into the x-ray emission is significantly enhanced when a laser prepulse precedes the main pulse. The details of x-ray line emission from solid targets irradiated by a pair of ultrashort laser pulses are investigated both theoretically and experimentally. Insight into spatial and temporal characteristics of the line x-ray source is provided by numerical simulations and a simplified analytical model. Optimal time separation of the laser pulses is searched for in order to reach the maximum conversion of laser energy into the emission of selected x-ray lines. We deduced how the optimal pulse separation scales with laser and target parameters.

Abstract This paper examines the characteristics and pricing of stocks that are actively traded by speculative retail investors. We find that stocks with high retail trading proportion (RTP) have strong lottery features and they attract retail investors with strong gambling propensity. Furthermore, these stocks tend to be overpriced and earn significantly negative alpha. The average monthly return differential between the extreme RTP quintiles is −0.60%. This negative RTP premium is stronger among stocks that have lottery features or arelocated in regions where people exhibit stronger gambling propensity. Collectively, these results indicate that speculative retail trading affects stock prices.

In the past twenty years, Israel has undergone extensive economic, social, cultural and political transformations. Ram's book develops an original analysis of contemporary Israel. Rather than limiting the study of Israel to its history and politics, the author situates current developments within the context of globalization, a new stage of capitalism at the intersection of the twentieth and twenty-first centuries. Drawing on Benjamin Barber, Ram claims that globalization is a dialectical process that simultaneously generates both liberalism (McWorld) and fundamentalism (jihad). While globalization affects the whole of Israeli society, the consequences for the winners and losers of the economic changes are not uniform. The former adopt a cosmopolitan and post-Zionist orientation while the latter are mobilized into tribalism, ethnic-nationalism and anti-Arab populism. The book is structured around the various themes of globalization: polarization, post-Fordization, Americanization, McDonaldization and post-nationalalization. Ram elegantly combines statistics, historical data and illustrative accounts in order to describe and examine contemporary changes within Israeli society. The globalization of Israel encompasses three interconnected transformations: a post-industrial revolution, a bourgeois revolution, and a consumerist revolution. In other words, an economic transformation from labor-intensive traditional industries to knowledge-based informational industries; the demise of the centralist welfare state system and the prioritization of private property which signals a major shift in the relationship between state and society; and a change in the lifestyle and material culture of individuals in Israel. These transformations have had varying implications for the different social classes. Globalization has had a polarizing outcome; not only has it exacerbated income and social gaps, but it has reshaped Israel's political orientation in general and particularly that related to the Israeli-Arab conflict. Business and political elites had an interest in abandoning nationalistic sentiments and thus have been in favor of reconciliation with the Palestinians. But, the lower classes have not had a direct economic interest in the government's retraction from the welfare state which has been supplanted by the channeling of resources to the settlers in the occupied territories. Nevertheless, Jewish chauvinism has empowered the lower classes symbolically. It is important to note that this book focuses chiefly on the globalization of Jewish-Israel and generally

In .. 374, Gregory, bishop of the small town of Nazianzus in the Cappadocian hinterland, delivered a funeral oration in praise of his father. Amongst many pious vignettes, Gregory o¶ered a thumbnail sketch of his father’s conversion to orthodoxy in 325 following an encounter with a party of bishops on their way to the Council of Nicaea. (Fortunately, it appears, these persuasive prelates were not supporters of Arius.) As a result of his conversations with these godly men, Gregory’s father abandoned his previous faith:‘[My father] was a branch sprung from a root not at all to be admired . . . To the humble they are called Hypsistarians, and the Pantokrator is the only god they worship’ (Or. 18.5; PG 35: 989D–992A). Like all good panegyrists, Gregory of Nazianzus revealed as much as he obscured. In quickly dismissing the Hypsistarians and their monotheistic theology, he sought both to marginalize the cult and to align it with other Christian heresies. But the Hypsistarians had a longer history than Gregory chose to imply. And their monotheism was more than a deviant or confused form of Christianity. In a μrst-rate paper—marked by a thoughtful use of epigraphic material, which might even have provoked an approving smile from Louis Robert—Stephen Mitchell plots a widespread cult of Theos Hypsistos (the Greatest God) dating back at least to the second century .. The cult involved some familiar polytheist elements, such as the o¶ering of votives for health or prosperity, but its adherents did not practise animal sacriμce, participate in civic festivals, nor represent their god in anthropomorphic form. Most strikingly, Hypsistarians developed a sophisticated understanding of an abstract, incorporeal, and distant deity mediated through angelic messengers such as Apollo. In its language and concepts, this theology shared much with contemporary Jewish and neo-Platonic thought. ‘By any deμnition this was one of the most spectacular demonstrations of religious syncretism that the ancient world has to o¶er’ (p. 121). Like Mitchell, other contributors to this volume are keen to expose the deep roots of monotheism in the Mediterranean world and to erode any comfortable sense that belief in One God was the exclusive preserve of a Judaeo-Christian tradition (orthodox or heretical), isolated from the classical world which surrounded and enveloped it. M. L. West examines monotheistic thinking in early Mesopotamian, Hebrew, and Greek religions; Michael Frede in the major philosophical schools of classical antiquity; John Dillon in the various monistic forms of Gnosticism; and Wolf Liebeschuetz in the syncretic arguments for a Supreme Deity advanced by Praetextatus in Macrobius’ Saturnalia. The cumulative impact and importance of these essays should not be underrated. Together they make a powerful case for the proposition ‘that not only philosophers, but a very substantial portion of late antique pagans was consciously monotheistic’ (p. 20). Moreover, they show that it is di ̧cult to conceive of the rise of Christianity as marking a simple movement from polytheism to monotheism, or for pagan monotheism to be understood as a belated rearguard response to Christian successes: ‘far from arising as a reaction to Christianity, pagan monotheism was a deeply rooted trend in ancient philosophy which developed under its own momentum’ (p. 20). That central concern to present a continuous history of monotheism also underpins the editors’ refusal to follow convention in understanding ‘late Antiquity’ as a 135

COVID-19 IMPACT ON THE MAIN GLOBAL STOCK INDEXES The aim of the study is to examine the impact of information on lockdown connected with COVID-19 on stock indexes. The hypothesis was: it is a strong impact of the lockdown announcement on stock indexes at the time of its announcement or cancelation. Panel event models were used to verify the hypothesis. The study used data from the Thomson Reuters Database for the period from 2.01.2019–10.05.2020. The analysis was based on the papers and reports on COVID-19 and the literature on behavioral finance.

The Wimmera Catchment Management Authority (WCMA) is responsible for approximately 30,000 square kilometres of land in the west of the state of Victoria in Australia. The predominant land use in the Wimmera is agriculture which is primarily responsible for the clearing of 85 percent of the region’s native vegetation. The 2003–2008 Wimmera Regional Catchment Strategy (WRCS) confirmed the natural resource management (NRM) priorities for the Wimmera Region. The Strategy document identified a number of current recommended practices (CRP), the adoption of which would contribute to the future sustainability of the region. Qualitative research identified thirteen critical CRPs that were investigated in a survey of land-management practices in the Wimmera. The research reported in this paper is based on the data collected in this survey of 1003 of the region’s landholders. Our research identifies the main determinants of the number of CRPs taken up by the region’s landholders as the size of landholding, direct government support and conservation education.

Summary: On day 21.5 a pregnant rat received a single injection of [1-14C]glycerol. The purpose was to study the transfer of glycerol through the placenta from the maternal to fetal plasma. From 3–20 min after injection the specific activity of glycerol in maternal and fetal plasma was measured. The results indicate that the mother can provide this molecule to the fetus. Similar results were obtained with the rabbit on day 28 of pregnancy.The possibility of the conversion of plasma glycerol to glucose has been investigated in the rat and rabbit fetus. This molecule was chosen chiefly to see whether the gluconeogenic pathway was functioning in the fetus above the triose phosphate step.At two stages of fetal development the capacity of the fetus to incorporate [1-14C]glycerol into glucose plus glycogen has been shown in the two species.In the rat fetus the conversion of [1-14C]glycerol to [14C)glucose increases from 19.5 to 21.5 days of gestation. For the rabbit this parameter increases from 25 to 28 days of gestation.On day 25 in the rabbit and day 19.5 in the rat the liver glycogen was labeled, but it did not accumulate the [14C]glucose from [1-14C]glycerol during the time that we have studied. In contrast, on day 28 in the rabbit and day 21.5 in the rat the incorporation of radioactivity increased as function of the time.However, the relative importance of glycerol as precursor of the glucose plus glycogen in the fetus remains to be elucidated.Speculation: The available evidence suggests that in the fetal rat liver the gluconeogenesis does not appear until after birth. Quantitatively, the most important source of glucose for the fetus must be the mother.The existence of glycerol in the plasma of the rat and rabbit fetus may contribute to produce glucose and increase liver glycogen reserves near term.

Scientists frequently communicate the results of their work in research reports. When writing scientific articles, authors must follow instructions and requirements of standard article format. A scientific paper should have in proper order, a Title, Abstract, Introduction, Material and Methods Results, Discussion, Conclusion and Literature. A title should be the fewest possible words that accurately describe the content of the paper. It should attract researchers' attention in order to be included in their investigation. An abstract is a short summary of the article. It concisely summarizes results and conclusion so that essential details of the paper can be understood in 100 - 250 words. The most commonly used are structured abstracts. Key words are provided below the abstract and describe the medical concepts characteristic for the whole article.

We developed a prototype design support system for generating illustration of a pictogram. A pictogram is a symbol representing a concept, object, activity, place or event by illustration. This pictogram is produced by the designer who gets an illustration more careful consideration and completes it after repeated trial and error. Thus to design pictograms is complicated process, and it is difficult for the general public to produce new design. This paper describes the automatic design system of a pictogram such that everybody can design it easily by combination of basic illustrations.

he effect of pass deformation on the microstructure of Al-Mg-Sn-Bi-Ga-In alloy anode was investigated by using SEM, TEM, and EBSD. The results show that when controlling the rolling deformation at 40%, the segregation phases on the Al alloy matrix was the best distributed for the reason of dynamic recrystallization procedure. The electrochemical and anti-corrosion results show that uniform distribution of segregation phase will improve the related properties of Al alloy anode. After optimizing the rolling procedure, the Al alloy anode has more negative electrode potential of about -1.585V(vs.Hg/HgO) and lower hydrogen evolution rate of 0.092mL/ (min·cm2)

Foods that are extensively handled during preparation and stored without refrigeration are often associated with staphylococcal food poisoning. This problem is more confounding when contaminating strains belong to the methicillin-resistant Staphylococcus aureus (MRSA) group. In this study, we investigated the survivability of methicillin-resistant S. aureus (MRSA) in two different seafood matrices at different storage conditions. MRSA was inoculated at 6 and 3 log cfu /g levels into all sample groups comprised of peeled shrimp ( Parapeneopsis stylifera ) stored at -20 o C, Bombay duck ( Harpadon nehereus ) stored in ice and dried Bombay duck stored at room temperature. The populations of MRSA in frozen peeled shrimp showed 1.52 log reduction in 6 log cfu /g inoculated sample, while in 3 log cfu/g inoculated sample, the counts remained more or less stable after 60 days of storage. In fresh Bombay duck inoculated with 6 log cfu /g and stored in ice for 18 days, MRSA count decreased by 2.75 log cfu /g . In contrast, MRSA counts remained stable in 3 log cfu /g inoculated Bombay duck stored in ice. However, the total viable count (TVC) in ice-stored Bombay duck increased by 3.02 log cfu /g over 16 days of storage. In dried Bombay duck stored at room temperature, MRSA count declined by 3.27 log cfu /g in 6 log cfu /g inoculated sample and by 0.91 log cfu/g in 3 log cfu /g inoculated sample. The results suggest that the survival of methicillin-resistant S. aureus depends on the temperature of storage and the inoculum size. In our study, MRSA exhibited better survival when inoculated at 3 log cfu /g irrespective of seafood matrix and storage temperature.

Three dimensional observation of individual dislocation lines constituting indentation rosette was made by electrolytic decoration. The majority of lines belonged to systems of loop families of {110} and {112}. From the structure, the formation of rosette was inferred to consist of the initial stage where the elemental glides operate, and the rearrangement stage where cross glide, climb, multiplication and network formation also operate. Upon applying external stress by bending and compression the rosette structure transformed to an arrangement more complicated than that expected. Causes of the complication are the plastic deformation and residual strains around indent. Mechanical and electrostatic motives may explain the characteristic transformation.

Proper extraction of fingerprint functions is important for matching the fingerprint algorithms. Different pieces of fingerprint information, such as rigid orientation and frequency should be taken into consideration for good results. The quality of a fingerprint image is often required to improve the function extraction process. In this article we introduce a Hybridized Garber Filter Algorithm (HGFA) for Fuzzy Fingerprint Image Feature Extraction for effective fingerprint recognition.This paper describes a fingerprint detection system consisting of image preprocessing, filtration, extraction and recognition matching.Preprocessing of images includes normalization based on median value and variation. In order to prepare the fingerprint image further processing, Gabor filters are extracted. The Poincaré index with a partitioning technique is used for the identification of a particular point. The extraction of the ridge line is shown and also the minute extraction with CN algorithm
