Raw Materials from U.S. Choice beef chucks boned 24 h postmortem and frozen boneless turkey thighs stored approximately 120 h were flaked and incorporated in four restructured formulations with each containing 1.0% NaCl and 0.25% sodium tripolyphosphate (STP). Formulations included beef (B), beef plus 0.5% sugar (BS), 50% turkey (BT) and 50% beef and 50% turkey plus 0.5% sugar (BTS). At 0, 21 and 84 day, subjective evaluations were conducted for discoloration, cohesiveness, muscle cut resemblance and overall appearance. Objective measurements included Hunter Color and TBA values. Overall appearance and discoloration (measured visually and objectively) were affected more by storage time than by raw materials and flavor adjuncts. The effect of raw materials and sugar on the sensory attributes was minimal except that the formulations containing turkey had higher TBA values.

The static and dynamic shear stress of newly developed electrorheological (ER) fluids can reach more than 100 kPa and over 60 kPa at 3 kV/mm, respectively. The high yield stress of those ER fluids and its near linear dependence on the electric field are different from the conventional ER fluids and can not be explained with traditional dielectric theory. Experiment demonstrates that the polar molecules adsorbed on the particles play crucial role in those ER fluids, which can be named as polar molecule type electrorheological (PM-ER) fluids. To explain PM-ER effect a model is proposed based on the interaction of polar molecule-charge in between the particles, where the local electric field is much higher than the external one and can cause the polar molecules aligning. The main effective factors for achieving high-performance PM-ER fluids are discussed.

Accounting has its development aligned with the progress of humanity. With globalization, the accounting area had to adapt to market needs. The professionals inserted in this evolution face significant challenges, of which the search for improvement must prevail. The objective was to analyze the impacts of the Technological Revolution on the accounting performance of professionals in the exercise of their duties and the new profile required with the innovation of the digital age. The methodological aspects included the accomplishment of bibliographical research, using references in the updated temporal nexus, with publications from 2015. The results indicate the extreme importance of the permanent improvement of accounting professionals, in search of constant changes inherent to the developed activities, because the valuation of the accounting profession will only happen if professionals are aware that the new challenges are opportunities for growth and expansion of the profession. This is the pace of digital innovation.

Miraglia, Gennaro J. (Bryn Mawr College, Bryn Mawr, Pa.) and L. Joe Berry. Enhancement of salmonellosis and emergence of secondary infection in mice exposed to cold. J. Bacteriol. 84:1173–1180. 1962.—The ld50 dose for mice of Salmonella typhimurium, strain RIA, is 4.1 × 105 for animals individually housed without bedding and maintained at 25 C. It is 3.8 × 103 for animals similarly housed but kept at 5 C. An intravenous injection of 0.1 ml of Proferrin 2 hr prior to infection with RIA lowers the ld50 to 4.9 × 103 and to 4.0 × 101 for mice kept, respectively, at 25 and at 5 C. Low environmental temperature and “blockade” of the reticuloendothelial system (RES) lower the resistance of mice to about the same degree, but low temperature and RES impairment together lower resistance as if each were acting independently. No effect of cold could be detected in mice infected with the highly virulent SR-11 strain of S. typhimurium, since all animals died after infection with only a few cells. Mice that were natural carriers of salmonellae, as judged by fecal discharge, were highly resistant to challenge and responded to cold in a manner similar to normal mice infected with RIA. Strain RIA could be isolated from the tissues of infected animals with greater frequency and persisted longer in mice maintained at 5 C than those at 25 C. Staphylococci were isolated from livers of animals that survived salmonella infection for 14 days at 5 C, and the incidence of staphylococci was proportional to the number of salmonellae injected. At 25 C, only a small percentage of mice had staphylococci in tissues and these occurred independent of the infectious dose of salmonellae. These observations were made on normal mice infected with RIA and on carrier mice infected with SR-11.

Freshly isolated rat islets were transplanted into the testis of diabetic mice. The intratesticular islet xenografts produced normoglycemia in the diabetic recipients. The survival time of the intratesticular xenografts was significantly longer than intrasplenic, intrahepatic, and renal subcapsular sites of transplantation of xenografts of freshly isolated rat islets. Three of the recipients with intratesticular islet grafts were still normoglycemic at 60 days after transplantation, and orchidectomy resulted in a return to the diabetic state. The findings indicate that the testis provided a more privileged immunologic site than either the spleen, liver, or kidney and the lower temperature of the testis apparently did not affect the function of the islet grafts since the recipients became normoglycemic.

The interview series in Rejuvenation Research is a unique and, I believe, highly valuable feature of the journal, giving readers insights into the thinking and motivation of some of the most influential movers and shakers in the many disciplines-not only scientific(1-5) but also political,(6) sociological,(7,8) ethical,(9,10) and more-that impinge on the crusade to defeat aging. This issue's interview features one of the world's most respected and admired researchers in the biology of aging as a result of her incisive evaluations of the work of others as well as the quality of her own research. Her clarity of thought and expression, to the general public as well as to colleagues, has contributed immensely to the process of communication between the field of biomedical gerontology and the many constituencies that will be affected by progress against aging-a dialogue that, as I(11-19) and others(20-26) have noted recently, is essential if we are to develop effective interventions against aging with all possible speed.

In Hawaii, soybeans planted in November through January will produce yields of 25 to 50 percent compared with those planted through June. Yield components were studied for several soybean cultivars to determine which one was the most sensitive to planting dates and if there were differences between cultivars.
Soybean cultivars, Amsoy 71, Davis, Forrest, Kahala, P.I. 297,550, and Williams were planted each month for two years. One November planting was lost, so there were 23 tests representing different environments. Each test consisted of 24 plots, six cultivars in four replications in a randomized block.
Analysis of variance of combined tests indicated significant differences between number of plants, pods per plant, seeds per pod, seed weight, yield of seed, plant height, and oil content of the seed that were due to data of planting, cultivar, and date × cultivar interaction.
Regression analysis indicated a closer relationship between pods per plant and yield during stress conditions (November through January plantings), whereas number of seeds per pod was more closely associated with yield during non-stress environments (April through June plantings).

In this paper, we explore how to better integrate virtual reality viewing to a smartphone. We present novel designs for casual (short-term) immersive viewing of spatial and 3D content, such as augmented and virtual reality, with smartphones. Our goal is to create a simple and low-cost casual-viewing design which could be retrofitted and eventually be embedded into smartphones, instead of using larger spatial viewing accessories. We explore different designs and implemented several prototypes. One prototype uses thin and light near-to-eye optics with a smartphone display, thus providing the user with the functionality of a large, high-resolution virtual display. Our designs also enable 3D user interfaces. Easy interaction through various gestures and other modalities is possible by using the inertial and other sensors and camera of the smartphone. Our preliminary concepts are a starting point for exploring useful constructions and designs for such usage.

The major objective of any electric distribution system (DS) operators in the present competitive market is to increase the service quality with improved reliability and lesser energy cost. This objective can be achieved by maintaining the balance between the reliability and cost of investments. In this work, system reliability is improved by using reserve capacity considering load growth. A sequential load growth model is presented for addition of load in non-integer years which is essential for sequential Monte Carlo simulation method. A model is presented to estimate the required reserve capacity if planning duration is known and vice versa. The concept of minimum allowable reserve capacity (MARC) is introduced to overcome the risk due to uncertain load growth. The system reserve capacity is increased by two ways i.e. up-gradation of distribution substation and integration of distributed generation (DG). The impact of load growth rate and reserve capacity level on system reliability is evaluated for a practical Indian distribution system. The required reserve capacity levels and capacity expansion duration are evaluated for different load growth rates and MARC values. Keyword: Sequential load growth, reserve capacity, capacity expansion, reliability, distributed generation.

Abstract Traditional operating systems’ architectures are primarily focused on achieving superior performance, albeit at the expense of sacrificing reliability. This approach is clearly inadequate, given our growing dependence on computer systems for essential and critical services. Reliability should thus be considered as a first-class citizen alongside functionality and performance, while designing future operating systems. The present paper summarizes the current trends and best practices employed to improve the reliability of operating systems. We also draw attention to the limitations and drawbacks of the prevalent approaches, discuss outstanding issues and propose some promising research directions, which may be explored to build highly reliable operating systems.

Malignant pleural mesothelioma is a rare malignancy arising from the mesothelial cells lining the pleural cavity. Individuals with prolonged inhalational asbestos exposure as in ship-building, plumbing, pipe fitting, etc., are at risk of developing mesothelioma, lifetime risk being as high as 8–13% [1]. As it usually takes decades to develop, it usually occurs among middle-aged and elderly people. Very rarely, it presents in younger age groups defying the classical presentation. It has an aggressive course and poor outcome. Pemetrexed is a commonly used chemotherapeutic agent in lung cancers. Its side effect profile includes hematological and non-hematological side effects. Hyperpigmentation in the absence of other cutaneous lesions is uncommon and only a few cases have been reported so far [2-4].

There are more than 9,000 polyfluorinated compounds developed for commercial use, some negatively impacting human health, and they are generally considered to be resistant to biodegradation. Only a limited number of studies have identified microbes with enzymes sufficiently reactive to defluorinate difluoromethylene carbon groups. ABSTRACT Perfluorinated carbon atoms in a diether linkage are common in commercial anesthetics, drugs, fungicides, and insecticides. An important chemical group comprising perfluorodiethers is the 2,2-fluoro-1,3-benzodioxole (DFBD) moiety. The fluorine atoms stabilize the molecule by mitigating against metabolism by humans and microbes, as used in drugs and pesticides, respectively. Pseudomonas putida F1 catalyzed defluorination of DFBD at an initial rate of 2,100 nmol/h per mg cellular protein. This is orders of magnitude higher than previously reported microbial defluorination rates with multiply fluorinated carbon atoms. Defluorination rates declined after several hours, and the medium darkened. Significant defluorination activity was observed with cells grown on toluene but not l-arginine. Defluorination required only toluene dioxygenase. Pseudomonas and recombinant Escherichia coli cells expressing toluene dioxygenase oxidized DFBD to DFBD-4,5-dihydrodiol. The dihydrodiol could be oxidized to 4,5-dihydroxy-DFBD via the dihydrodiol dehydrogenase from P. putida F1. The dihydrodiol dehydrated with acid to yield a mixture of 4-hydroxy-DFBD and 5-hydroxy-DFBD. All those metabolites retained the difluoromethylene group; no fluoride or dark color was observed. The major route of DFBD-4,5-dihydrodiol decomposition produced fluoride and 1,2,3-trihydroxybenzene, or pyrogallol, and that was shown to be the source of the dark colors in the medium. A mechanism for DFBD-4,5-dihydrodiol transformation to two fluoride ions and pyrogallol is proposed. The Pseudomonas genome database and other databases revealed hundreds of bacteria with enzymes sharing high amino acid sequence identity to toluene dioxygenase from P. putida F1, suggesting the mechanism revealed here may apply to the defluorination of DFBD-containing compounds in the environment. IMPORTANCE There are more than 9,000 polyfluorinated compounds developed for commercial use, some negatively impacting human health, and they are generally considered to be resistant to biodegradation. Only a limited number of studies have identified microbes with enzymes sufficiently reactive to defluorinate difluoromethylene carbon groups. The present study examined one important group of commercial fluorinated chemicals and showed its rapid defluorination by a bacterium and its key enzyme, a Rieske dioxygenase. Rieske dioxygenases are common in environmental bacteria, and those closely resembling toluene dioxygenase from Pseudomonas putida F1 are candidates for biodegradative defluorination of the common 2,2-fluoro-1,3-benzodioxole (DFBD) moiety.

This study was a formative evaluation of a peer tutoring package. The purpose was to investigate the effects of a peer tutoring package on the instructional performance of behaviorally disordered adolescents, directly trained by their teachers, and subsequent effects on the performance of their learners. Generative effects of the peer tutoring procedures were observed in successive peer tutor-learner dyads not directly trained by teachers. This study used an across subject multiple baseline design to study peer instructional behavior during daily training sessions and concomitant learner spelling performance. Results showed that learner performance on daily spelling tests increased considerably when intervention in the form of peer instruction occurred. Peer use of the instructional strategy varied greatly but all peer tutors consistently used the recordkeeping and graphing strategies as presented in the peer teaching package.

Nanocrystalline cellulose (NCC) has many potential applications because of its special properties. In this paper, NCC was prepared from bamboo pulp. Bamboo pulp was first pretreated with sodium hydroxide, followed by hydrolysis with sulfuric acid. The concentration of sulfuric acid and the hydrolysis time on the yield of NCC were studied. The results showed that sulfuric acid concentration had larger influence than the hydrolysis time on the yield of NCC. When the temperature was 50oC, the concentration of sulfuric acid was 48wt% and the reaction time was 30 minutes, a high quality of nanocrystalline cellulose was obtained; under these conditions, the length of the nanocrystalline cellulose ranged from 200 nm to 500 nm, the diameter was less than 20 nm, the yield was 15.67wt%, and the crystallinity was 71.98%, which is not only higher than those of cellulose nanocrystals prepared from some non-wood materials, but also higher than bamboo cellulose nanocrystals prepared by other methods.

Nail–patella disorder or syndrome (NPS) is a pleiotropic autosomal-predominant confusion. Nail-patella disorder is an autosomal prevailing issue portrayed by dysplasia of finger nails, skeletal peculiarities, and, as often as possible, renal illness. The predominance of nail-patella disorder is evaluated to be 1 in 50,000 people. Transformations in the LMX1B quality cause nail-patella disorder. The LMX1B quality gives directions to delivering a protein that connects to particular districts of DNA and controls the movement of different qualities. Be that as it may, a standout amongst the most genuine appearances of NPS is kidney illness, which might be available in up to 40% of influenced people. Kidney malady in NPS appears to happen all the more frequently in a few families with NPS, however it doesn't isolate with a specific transformation sort or area. Around half of influenced people display cloverleaf pigmentation of the inward edge of the iris. The most genuine part of NPS is the nephropathy; however this doesn't happen in all patients with the disorder. The nail-patella disorder is an uncommon sickness of autosomal prevailing nature. It is related to musculoskeletal, dermatologic (nail dystrophy), renal, eye and gastrointestinal changes. The most successive orthopedic dissension of these patients is patellar unsteadiness connected with torment and practical restraint. All in all, in this innate patellar change, symptoms onset just happens when stride begins. A little minority (5–10%) of people with NPS create nephrotic-range protein urea as right on time as youth or youthful adulthood and advancement to end-stage kidney disappointment over variable timeframes.

: Prevention of obesity among children is a public health issue, and requires close monitoring of those with a tendency to gain weight. Most researchers believe that obesity, which has appeared since childhood and is maintained until adolescence, is much more difficult to treat. Obesity among children inevitably decreases life expectancy. The problem of overweight and excessive growth of obesity since childhood can be prevented or slowed down by implementing diversified programs, if society focuses more on the causes. There are many causes, some more crucial than others, but a balanced diet, combined with systematic physical activity, can prevent obesity and overweight in all children around the world. Next, I will present the studies done internationally regarding the presence of obesity and overweight in children aged 6-11 years.

Patients with a chronic and severe substance-use disorder who also have a history of posttraumatic stress disorder (PTSD) are thought to have a unique set of problems. The present study assessed psychiatric disorders, psychosocial problems, and traumatic events with structured interviews in 747 men and 693 women enrolling in urban opioid substitution treatment programs from 1995 to 2001. Participants with versus without a history of PTSD were more likely to have a history of many other psychiatric disorders and demonstrated more current and historical medical, employment, family/social, and psychiatric problems. PTSD was generally unrelated to substance-use disorder severity or diagnoses, with the exception of an increased risk of alcohol dependence. Women were more likely than men to have experienced sexual assault, and less likely to have been physically assaulted, although these events precipitated PTSD at equivalent rates across gender. In contrast, witnessing or hearing about the death or injury of others was more likely to precipitate PTSD in women than men. Female gender, exposure to combat, sexual assault, or physical assault, and a history of major mood or anxiety disorder were the best predictors of PTSD in this group. Study limitations are noted.

Hsi WL, Chai HM, Lai JS: Comparison of pressure and time parameters in evaluating diabetic footwear. Am J Phys Med Rehabil 2002;81:822–829. Objective Although peak pressure has been used in the evaluation of diabetic footwear, other potential parameters have remained unstudied. This study was undertaken to compare the effects of diabetic footwear on pressure-time integral, peak pressure, and contact time in different areas of the foot. Design In-shoe pressure was measured and analyzed separately in the left and right feet of 14 diabetic patients with neuropathy by using 24 discrete sensors for each foot; pressure-time integral, peak pressure, and contact time at 48 data points were compared between patients wearing their own shoes and patients wearing diabetic footwear. Results The three parameters were symmetrically reduced in the anterior and posterior parts of bilateral feet and increased in the middle part of bilateral feet. The 34 sensors that showed significant changes in pressure-time integral included all 23 sensors that showed significant changes in peak pressure, and 15 of 18 sensors showed significant changes in contact time. The change of the pressure-time integral was correlated to walking speed at 17 sensors, sex at five, body mass index at four, and speed difference at two. Conclusions The effect of diabetic footwear is detected at more sensors by pressure-time integral than by peak pressure and contact time. The slower a patient walks, the greater the change of the pressure-time integral by diabetic footwear. It is suggested that pressure-time integral be routinely included in the evaluation of diabetic footwear for each patient.

Recent genetic studies of Drosophila melanogaster and subsequent biochemical analysis in mammalian cells revealed that products of tuberous sclerosis genes, TSC1 and TSC2, regulate insulin signaling via suppression of p70 ribosomal S6 subunit-kinase (S6K) activity. In this study, using transplantation in the nude mouse, we found that the growth of a renal tumor cell line from Tsc2 knockout mouse was suppressed by the treatment of rapamycin, an inhibitor of mTOR (mammalian target of rapamycin) which is an upstream activator of S6K. The robust in vivo effect of rapamycin suggests that it can be used for chemotherapy of tuberous sclerosis-associated hamartomas and tumors. Other yet undiscovered chemicals selectively downregulate mTOR-S6K pathway may provide new therapeutic drugs for tuberous sclerosis.(Communicated by Takashi SUGIMURA, M. J. A., Jan. 14, 2003)

Valve-sparing aortic root repair (V-SARR) using the David reimplantation method is an increasingly popular alternative to composite valve graft aortic root replacement in patients with aortic root aneurysms or dissections who wish to avoid anticoagulation. Computed tomography (CT) with retrospective electrocardiograph (ECG)-gating has become routine before and following V-SARR at Stanford. CT allows accurate measurement of aortic dimensions and provides unprecedented three-dimensional (3D) images of the sinuses, the aortic valve cusps, and coronary arteries in patients with the Marfan syndrome (MFS), with a bicuspid aortic valve (BAV), or other aortic diseases. This helps the surgeon to conceptualize the size of the aortic grafts required and how much reduction is necessary proximally (aortic annulus) and distally. These maneuvers are used to reduce the aortic annular diameter (when necessary) and replace the sinuses and ascending aorta (T. David-V, Stanford modification V-SARR). Postoperative ECG-gated CT confirms the reconstructed geometry and reliably detects coronary or other anastomotic problems.

9543 Background: To identify clinical factors associated with prostate cancer-specific mortality (PCSM), adjusting for co-morbidity, in elderly men with intermediate-risk prostate cancer treated with brachytherapy alone or in conjunction with external beam radiation therapy (EBRT).
METHODS
The study cohort comprised 1,978 men of median age 71 (interquartile range [IQR], 66-75) years with intermediate-risk prostate cancer (Gleason score 7 with PSA 20 ng/mL or less and tumor category T2c or less). Fine and Gray's multivariable competing risks regression was used to assess whether presence of cardiovascular disease (CVD), age, treatment, year of brachytherapy, PSA level, or tumor category were associated with the risk of PCSM.
RESULTS
After a median follow up of 3.2 (IQR, 1.7 - 5.4) years, 15 men were observed to experience PCSM. The presence of CVD was significantly associated with a decreased risk of PCSM (AHR 0.20, 95% CI 0.04 - 0.99, P = 0.05), whereas an increasing PSA level was significantly associated with an increased risk of PCSM (AHR 1.14, 95% CI 1.02 - 1.27, P = 0.02). In the absence of CVD, cumulative incidence estimates of PCSM were higher (P = 0.03) in men with PSA levels above as compared to the median PSA level (7.3 ng/mL) or less; however, in the setting of CVD there was no difference (P = 0.27) in these estimates stratified by the median PSA level (6.9 ng/mL).
CONCLUSIONS
Detection of intermediate-risk prostate cancer in elderly men without CVD at lower PSA levels is associated with a lower risk of PCSM; this risk reduction is not observed in men with known CVD. [Table: see text] No significant financial relationships to disclose.

Influenza: the burden of disease in children c The burden of influenza infection in children is unknown. In a multisite cohort study, investigators prospectively enrolled children younger than 5 years who either had been hospitalized or who had presented to clinics and emergency departments in 2000–2004 with symptoms of acute respiratory tract infection or fever. Infection was confirmed by a positive polymerase-chain-reaction assay or viral culture for influenza A or B. Among 2797 hospitalized children, 6% had laboratory-confirmed influenza. Infection was significantly more common in infants (age range, 0–5 months; 49%) than in older children (age range, 24–59 months; 20%). Among children aged 6 months and older, fewer than 25% of parents reported that their child had been vaccinated against influenza. Only 28% of confirmed cases had discharge diagnoses of influenza. The annual hospitalization rate associated with influenza averaged 0.9 per 1000 children and was significantly higher in infants than in older children (4.5 vs. 0.3 cases per 1000). Among 1742 children seen in clinics or EDs, 16% had confirmed influenza. Infection was significantly less common in infants than in older children (7% vs. 52%). Among children aged 6 years and older, fewer than 30% of parents reported that their child had been vaccinated. Only 17% of confirmed cases had discharge diagnoses of influenza. During the 2002–2003 influenza season, influenza infection was associated with 50 clinic and 6 ED visits per 1000 children. corresponding numbers for 2003–2004 were substantially higher (95 and 27 per 1000).

We have used mRNA differential display to identify a novel high-glucose-regulated gene (HGRG-14) in human mesangial cells cultured for up to 21 days in 30 mM d-glucose. The mRNA of HGRG-14 seems to be regulated post-transcriptionally and encodes a small polypeptide of molecular mass 13 kDa. The native protein occurs as a dimer. The recombinant protein is a substrate for casein kinase II kinase. At high glucose concentrations, HGRG-14 protein levels decrease. This correlates with the appearance of a long form of HGRG-14 mRNA under high-glucose conditions. This form has a long 3' untranslated region containing several ATTTA RNA-destabilizing sequences and has a short half-life. A truncated, more stable mRNA that lacks the long 3' untranslated region is produced at 4 mM d-glucose. The switch from the truncated to the long-form transcript is detected within 2 h of exposure to 30 mM d-glucose, indicating that hyperglycaemic conditions have an acute effect on HGRG-14 mRNA processing.

Evolutionary algorithms (EAs) provide unique advantages for optimizing neural networks in complex search spaces. This paper introduces a new web platform, NeuroEvo (neuroevo.io), that allows users to interactively design and train neural network classifiers using evolutionary and particle swarm algorithms. The classification problem and training data are provided by the user and, upon completion of the training process, the best classifier is made available to download and implement in Python, Java, and JavaScript. NeuroEvo is a cloud-based application that leverages GPU parallelization to improve the speed with which the independent evolutionary steps, such as mutation, crossover, and fitness evaluation, are executed across the population. This paper outlines the training algorithms and opportunities for users to specify design decisions and hyperparameter settings. The algorithms described in this paper are also made available as a Python package, neuroevo (PyPI: https://pypi.org/project/neuroevo/).

Objective: To investigate changes in the quality of life of patients with leg ulcers being treated in community leg ulcer clinics. Design: Patients were interviewed using a standard questionnaire, and then reinterviewed after 12 weeks of compression bandaging to observe changes. Setting: Community ulcer clinics held in health centres within Riverside Health District. Patients: All new patients presenting to community leg ulcer clinics up to 6 months from the start of a clinic and treated with four-layer compression bandaging. Main outcome measures: Changes in quality of life, interference in daily activities caused by leg ulceration and general health after 12 weeks of treatment. Results: Treatment over 12 weeks resulted in a mean reduction in anxiety (2.79 v 1.73, p < 0.001), depression (2.61 v 1.89, p < 0.001), hostility (1.59 v 1.00, p < 0.001) and cognition (1.29 v 0.87, p = 0.015). Pain significantly improved following treatment (χ2 trend = 103.7, 1d.f., p < 0.001). Changes in depression and hostility were related to complete ulcer healing. Conclusions: There were clear changes in quality of life following 12 weeks in a community leg ulcer clinic, which were related to the healing of the ulcer. Systems of care that offer rapid healing and improve patients' well-being must be considered when planning an effective leg ulcer service.

Artificial Intelligence (AI) came up as an ambiguous concept from computer sciences and now it is being used in many areas of our life. It has stimulated academia’s interest due to its alternative insights into complex problems. Therefore, a bibliometric method was applied in this study to observe the progress of AI in the tourism field. A total of 102 papers were collected from Scopus database. Key factors such as most productive authors, collaborations and institutions were identified, and research hotspots were determined using co-occurrence network and most common author keywords. Progress of AI was visualized with thematic evolution analysis. Findings indicate that there is a progressive interest in AI after 2017, and average citations signify that papers are highly cited. Since this is the first study conducting a bibliometric on AI in the tourism context, it could be considered useful for academics and tourism professionals as it provides general overview of AI, demonstrates research trends and popular papers.

The modern diamond industry is an important link in the global economy. Industry extraction and export of rough diamonds provide a significant portion of GDP in the economies of many developing countries. Developed countries, such as Belgium, the Netherlands, Israel, the UK, gain substantial profits from the processing, sorting, cutting diamonds coming and, of course, the further distribution of final products. This sector is of great economic and social interest for Russia, which today is the largest supplier of diamonds to the world market (in physical volumes). The majority of natural diamonds are used in jewelry, and the total amount of end- products exceeds estimated more than 70 billion dollars. However, the modern diamond industry faces a number of structural problems that can drastically change the image of the sector over the next 5 years.

Using Surface Differential Reflectivity (SDR) we have studied the optical properties of a PbSe(100) surface obtained by cleaving a PbSe sample in ultra-high-vacuum environment. SDR showed the existence of a gap of approximately 1.6 eV. The derived surface dielectric function showed, in the energy range of the present study (1.2–3.6 eV), three optical transitions observed at energies of 1.59, 2.01 and 2.39 eV. By putting together angle resolved photoemission data and theoretical calculations, these transitions have been, tentatively, assigned to different points in the surface Brillouin zone.

This paper deals with the derivation of (i) the MLE (ii) the MVUE (iii) a Bayes estimator of the probability in the title, for the case p = 2. Simulation studies are carried out to compare these estimators. The results suggest that the MLE and the Bayes estimator are biased and the Bayes estimator have the smallest MSE. In the general case, explicit expression for the probability in the title is derived and the MLE and Bayes estimator are obtained. A general method of deriving the MVUE is pointed out. Because of the simulation studies for p = 2 it is recommended that the Bayes or predictive estimator should be used.

We present two decentralized iterative power control algorithms (IPCAs) for the uplink and downlink communication in multi-service CDMA wireless environment. The proposed dynamic IPCAs are decentralised in the sense that they can be implemented in a distributed mode at the individual cell sites and mobile stations based on local measurements and information, and without the need of co-ordination between the different cells. The main feature of these two power control algorithms is that they combine the allocation as well as the correction of power in a multi-service wireless system. For the algorithms presented here whenever power settings exist for which all users meet the QoS requirements we prove and demonstrate exponentially fast convergence to the optimal power values. Finally we present some numerical results to assess the performance of our algorithms by applying them in some test cases.

A healthy urban forest is important to improve both human health and overall environmental quality. There is currently a lack in technology that has the ability to evaluate living trees in their natural environment without invasive destructive sampling. This work presents a cost-effective, real-time microwave tomography system for practical forestry applications. The scattering measurement system is designed using wide band microstrip monopole antennas (1--5 GHz) and coupled to a switching matrix and a controlling software for automated real-time data collection. A time reversal signal processing algorithm is developed for performing imaging, based on the measurements. The imaging system is initially validated by imaging simple cylindrical targets and finally utilized for imaging defects in different tree trunk samples. Preliminary experimental results demonstrate the practicality, novelty and benefits of this approach for forestry imaging applications.

Aβ-peptide ligands based on a cis-glycofused benzopyran structure have been fluorescently labeled using coumarine derivatives. Among the synthesized compounds, two conserved their binding ability to β-amyloid peptides, as shown by NMR experiments. Moreover, exploiting its fluorescent property, it was demonstrated that one of such compounds was able to cross an in vitro model of blood–brain barrier (BBB) and to stain Aβ‑deposits.

Dopaminergic medication is widely used to alleviate motor symptoms of Parkinson's disease (PD), but these medications also impact cognition with significant variability across patients. It is hypothesized that dopaminergic medication impacts cognition and working memory in PD by modulating frontoparietal-basal ganglia cognitive control circuits, but little is known about the underlying causal signalling mechanisms and their relation to individual differences in response to dopaminergic medication. Here we use a novel state-space computational model with ultra-fast (490 msec resolution) fMRI to investigate dynamic causal signalling in frontoparietal-basal ganglia circuits associated with working memory in 44 PD patients ON and OFF dopaminergic medication, as well as matched 36 healthy controls. Our analysis revealed aberrant causal signaling in frontoparietal-basal ganglia circuits in PD patients OFF medication. Importantly, aberrant signaling was normalized by dopaminergic medication and a novel quantitative distance measure predicted individual differences in cognitive change associated with medication in PD patients. These findings were specific to causal signaling measures, as no such effects were detected with conventional non-causal connectivity measures. Our analysis also identified a specific frontoparietal causal signaling pathway from right middle frontal gyrus to right posterior parietal cortex that is impaired in PD. Unlike in healthy controls, the strength of causal interactions in this pathway did not increase with working memory load and the strength of load-dependent causal weights was not related to individual differences in working memory task performance in PD patients OFF medication. However, dopaminergic medication in PD patients reinstated the relation with working memory performance. Our findings provide new insights into aberrant causal brain circuit dynamics during working memory and identify mechanisms by which dopaminergic medication normalizes cognitive control circuits.

Abstract Surgical management of the developmental malformations of newborns, infants, and children needs centralization not only from a professional point of view but because of financial reasons, too. During the past 2‐3 decades, the reduction in the number of live births in Hungary and the increase in the changing of professional needs have witnessed the centralization of the more expensive, fragmented intensive/surgical care. In a relatively small country, like Hungary, centralization is essential.

The Solar Flux Radiometer aboard the Pioneer Venus Sounder Probe operated successfully during its descent through the atmosphere of Venus. The instrument measured atmospheric radiance over the spectral range from 400 to 1800 nm as a function of altitude. Elevation and azimuthal measurements on the radiation field were made with five optical channels. Twelve filtered Si and Ge photovoltaic detectors were maintained near 30°C with a phase-change material. The detector output currents were processed with logarithmic transimpedance converters and digitized with an 11-bit A/D converter. Atmosphetic sampling in both elevation and azimuth was done according to a Gaussian integration scheme. The serial output data averaged 20 b/s, included housekeeping (sync, spin period, sample timing and mode). The data were used to determine the deposition of solar energy in the atmosphere of Venus between 67 km and the surface along with upward and downward fluxes and radiances with an altitude resolution of several hundred meters. The results allow for more accurate modelling of the radiation balance of the atmosphere than previously possible.

Ethyl NN-dimethylcarbamate, isopropyl NN-dimethylcarbamate, and t-butyl NN-dimethylcarbamate undergo β-elimination during gas-phase thermolysis; the influence of structure on rates and activation energies shows that the reactions which are unimolecular involve heterolytic rather than homolytic bond fission and support an unsymmetrical transition state.

Navicular syndrome (navicular disease) plays a major role in the equine industry as a chronic, degenerative, and often career-limiting disease process, affecting a variety of breeds of horses. In addition to clinical signs and diagnostic analgesia, diagnostic imaging plays a key role in the identification of this disease process; radiography is the most widely used imaging modality. In addition to their clinical utility, foot radiographs are a standard element of most pre-purchase examinations. Good radiographic quality and positioning are necessary for accurate interpretation. Radiographic lesions of the navicular bone, such as sclerosis, enlarged synovial invaginations, distal border fragments and flexor cortical erosions, are important to identify and understand because of their potential role in the disease process. This article reviews an approach to radiological evaluation and interpretation of lesions affecting the navicular bone.

One of the most significant characteristics of the peace process in Northern Ireland has been the profound importance attached by a range of academic, political and non-governmental actors to the concept of human rights. However, unionists, more so than other elite-level political actors in Northern Ireland, have expressed scepticism about proposals from the Northern Ireland Human Rights Commission (NIHRC) for a Northern Ireland Bill of Rights. This article explores how unionists relied on a ‘court sceptic’ narrative to argue against the Bill of Rights proposals. It argues that at one level unionist reliance on ‘court sceptic’ arguments can be conceived of as instrumental in the sense that it was a mere tactical response to, as unionists argue, the inflation by the NIHRC of their mandate contained in the Good Friday Agreement to devise a Bill of Rights. However, at another level unionists reliance on ‘court sceptic’ arguments can also be traced to their constitutional experience within the British polity.

Michael Pickering’s new book Stereotyping: The Politics of Representation is the best survey of the study of the vexed and vexing practice of ‘stereotyping’ I have yet encountered. It will be an invaluable resource for advanced undergraduate and masters students in media and cultural studies and for students in related disciplines. They will find in this book a survey that is both critical and generous. More than this, however, they will find a marker of the development of cultural studies over the past 30 years. Stereotyping bears the hallmark of Pickering’s earlier work in which he has demonstrated a long-standing intellectual interest in culture, history and experience. His previous single-authored book, History, Experience and Cultural Studies, was a beautifully crafted, but, as yet, undervalued work in which he appealed to academics both ‘to keep faith’ in the ability of ‘ordinary men and women’ to make sense of their lives and to resist the ‘enormous condescension of poststructuralism’. Pickering’s previous work has also been marked by a strong concern for social justice centring on the politics of race and ethnicity. In writing this book, Pickering is setting himself a dauntingly complex and interrelated set of tasks. First, he seeks to clear the clutter around the basic idea of stereotyping and the stereotype. Second, he examines the practice of stereotyping in the movement from early 20th-century modernity to late 20th-century postmodern society. Third, Pickering looks at the place of the concept of ‘stereotyping’ in the development of cultural studies and emphasizes the changing practices of a politics of representation. Finally, he wants to do this without writing people and their direct experiences out of history. He begins, then, with the task of clearing the decks by, for example, distinguishing between categorizing and stereotyping and between categories and stereotypes. However, in the process of dealing with these and other problems, he creates others. Take the following brief extracts for example. Pickering refers to: ‘the dilemma which stereotyping faces’ (p. 3); ‘Stereotyping functions precisely in order to forget this dilemma’ (p. 4); ‘In approaching stereotyping as a process for maintaining and reproducing the norms of conventions of behaviour, identity and value, the intention is to extend and refine this definition in relation to the various areas and themes discussed in the rest of the book.’ (p. 5) (my emphases). I do not think it is nit-picking to say that the language used here is problematic. We should note that it is people who face dilemmas not stereotyping! And we should also note

Zusammenfassung Im alt-griechischen Text von Jes 11,2 und 33,6 steht εὐσέβεια (»Frömmigkeit«) anstelle von φόβοϛ (»Angst«) für das erste Wort des Satzes יהוה יראת (»Die Angst vor dem Herrn«). Dieses kommt dem Stil, der Semantik und der Theologie der Übersetzung zugute. Die »Frömmlichkeit« betont die Poesie von 11,2b und die Parallelen zwischen 11,1–9 und 33,3–8. Die »Frömmigkeit« vermeidet es außerdem, das Fromme mit der negativen Semantik der »Angst« (d. h. der Angst vor göttlicher Bestrafung) zu charakterisieren, die im unmittelbaren Kontext vorhanden ist (10,24–34; 33,3,8–8). Die »Frömmigkeit« trägt zu einem kumulativen theologischen Porträt von Zions Begegnung mit dem Gericht Gottes bei: Während die Frommen gerettet werden (33,5–6), werden die Gottlosen eschrocken sein, wenn der fromme Davidische Herrscher sie von Zion befreit (11,2b.4; 33,5–6.14; 59,20).

If only we could all meet over dinner! The problem with peer commentary-excellent and sobering as it is-is the lack of immediate feedback, the inability to put to rest at once the misgivings or the misreadings, the long delay between comment and response. Perhaps computer networking will someday substitute for commensal conversation: It will be almost as fast, but not nearly as much fun. But let me start by observing that as a relative outsider to the world of social psychology (although I did study it in the old Social Relations Department at Harvard in the late 1950s), I was delighted to meet all these (mostly new) colleagues and to acknowledge my delight in their incisive but fair criticism, tolerance of eccenticity, and general good humor. I think the content of my stereotype of social psychologists has been changed for the better by this encounter. (I won't elaborate on what that content was; I think they can probably guess.) One problem is, however, raised by the very fact that the respondents are-all but one-social psychologists. Naturally they tend to deal with what they know best; but this leaves three quarters of the paper uncommented on, except obliquely or briefly. Thus, practically everyone has a go at the Kahneman and Tversky "base-rate versus individuation" issue, but no one tackles the equally important part on Strawson's moral philosophy, and only Masters, himself a political philosopher, treats at all with Hume-with what I consider the central part of the argument. And even though I thought it was quite an important part of my demonstration, no one tackled my one empirical example of Charles Lamb-except again very obliquely. Thus, we have a somewhat lopsided set of comments here that do not, I think, come to grips with the totality of the paper. I gather philosophers were invited but did not respond (except for Masters). Given the way the academic game is played (no payoff for them in contributing to a psychology journal), this is understandable, if a little depressing; but it is also a pity because I could have ditched the whole Kahneman and Tversky example (or substituted another) without any great loss to the argument. But Hume, Strawson, and Lamb I feel I need. I don't need Star Trek either. Obviously this was popped in there because the article began as a lecture to a general university audience and I wanted some point of contact with people-particularly students-who might not be in the behavioral sciences or philosophy at all. But equally obviously, this example touched a nerve, both at the lecture and with some of the commentators. This is in itself very interesting as a phenomenon, and confirms this Trekker's (not Trekkie's, please) belief in the power of the Star Trek paradigm (or whatever). So for the present I just have to deal with the truncated commentary and do my best with it, while perhaps reminding the contributors, from time to time, that I am not so much concerned with the social psychology of stereotyping as with the more general philosophical/psychological issue: "What happens when we think, and why does it happen the way it does?" (I like this formulation better than "How does the mind work?" which perhaps begs too many questions.) This in turn leads to the question: "What does this tell us about the nature of human reasoning?" This question intrigues me because reason (usually equated with logical reasoning) is so often cited as the crucial feature distinguishing us from the beasts; We are, after all, Homo sapiens sapiens. Here once again, Hume's skepticism sets the agenda for the modern way into that question. The issues of stereotyping/ categorizing are themselves ways into Hume's question, and Kahneman and Tversky offered a way into these issues. I chose Kahneman and Tversky deliberately because of their bemoaning of the parlous state of human reasoning, and therefore their implicit acceptance of an ideal of reasoning that equated it with the perfectly logical-the "finished"mind: the "Spock syndrome," if you like. This was really a way to draw psychologists into the fundamental problem as stated by Hume, and elaborated on by Strawson, and ultimately into my notion that Hume had in fact proposed the correct solution to his problem without realizing it. In that solution lay the answer to those basic questions about thought and reason: the Darwinian answer, the adaptational answer, or however you want to phrase it (except as the "sociobiological" answer: more on this later). Since the idea of stereotyping is inextricably linked to that of prejudice, I felt obliged to try to make the link as I saw it. The first version of the essay in fact did not do this and stuck to the philosophical issues as such. Its title was "Reason and the Unfinished Mind" or something such; it is long since erased. But when it came to be rewritten as a public lecture, Felix Browder suggested that I expand it to cover the prejudice issue, and so I dug up Charles Lamb, Paul Robeson, Berrnhard Goetz, Rudyard Kipling, and a few other things to try to help make the link. I obviously disturbed a hornet's nest in the process. I fear that, like the unhappy Queen Gertrude, the author doth protest too much. But I thought this little explanation might help to clear the decks concerning my intentions in the

In 1969, James L. Massey and the author expressed the conviction that an interdisciplinary approach to the theories of automatic control and of error-correcting codes could, because of common algebraic content, result in advances in each field at that time. They pointed out that the cross-contributions promised to come from the unified study of the relatively general and abstract viewpoint of control and of the specific and intricate techniques of coding. Having spent about eighteen months doing preliminary studies, the authors had found evidence of interdisciplinary interest on the part, of groups specializing in adaptive processes, switching and automata theory, coding theory, information theory, circuit and system theory, and automatic control theory, together with an interest by electrical engineers in general. Encouraged by the interest and the preliminary results, Massey and Sain proposed formal investigations of this interdisciplinary frontier, to formulate problems in coding as general problems in dynamical system theory, to formulate problems in control as problems in coding theory, to determine thereby new solutions and techniques in both areas, to establish the significance of these solutions and techniques, to subsequently merge known results in coding and control theories, and to isolate during the progress of the work any basic differences between the two areas. Looking back upon those early goals, it is certainly true that some of them have seen a great deal of progress over the years, and others are yet today in progress. The primary goal of this paper is to discuss the early results; and the focus is placed upon the first five years.

この論文は，バブルの清算から現在までの厳しい環境変化に翻弄された日本の生命保険会社の経営効率の変化を追う中で，生命保険業を対象に生産関数を推計する際の課題を明確化にすると共にそれを踏まえた新しい経営効率指標の提案を目的とする。経営効率性の計測にどのような関数形（コブ・ダグラス型，トランスログ型など）や計測方法（パラメトリック，ノン・パラメトリック）を用いても，生産物の選択により，生産性の計測結果が大きく左右される。生産関数の推計には，保険会社の行動原理にあった生産物の選択が求められる。個別会社の生産性の計測には，修正基礎利益を生産物とした生産性が重要であり，確率的フロンティア生産関数の手法により計測した生産性を標準偏差で除した「E/R指数」が，生命保険会社の経営効率を評価する指標としてふさわしい。

The numerous publications on developmental cataract, as summarized by Nettleship, 1 Harman, 2 Groenouw, 3 Clausen, 4 and Waardenburg, 5 have tended to show a uniformity in the type of cataract observed within any family line. Nevertheless, it is sometimes found that certain of the cataractous persons in a given pedigree have a type of opacity of the lens significantly different from that presented by the remaining affected members of the family (Knies, 6 Gjersing, 1878, quoted from Harman, 2 Nettleship , Harman, 8 Groenouw, 3 Halbertsma, 9 Walsh and Wegman 10 ). This fact has been commented on by various observers, and a question raised from time to time as to the etiologic relationships of the various types. The present paper will de- scribe a genealogy of 123 people, 44 with cataract, which is remarkable for the variety of forms the cataract assumes, and will discuss the question of the genetic

Mathematical and computational modeling has been a great ally in the development of new drugs. It helps by providing preliminary results that ultimately guide the path that the tests should take. Thus, the objective of this work was to develop the PharmaLab computational tool, which simulates the pharmacological action in the mouse ventricular myocyte using the mathematical model of Mullins & Bondarenko (2013). Having as one of the main differentials the integration with a model for the force of contraction, at PharmaLab it is possible to perform pharmacological tests by changing parameters of the mathematical model and registering drugs to be used in the simulations. The computational tool has its own interface for plotting results and support material for educational use. As a demonstration of the tool, a validation was performed, comparing simulations with experimental data for the drug Niferidil and two “in silico” tests: SS-68 correcting the “Catecholaminergic Polymorphic Ventricular Tachycardia” (CPVT) and Niferidil correcting the Short QT Syndrome (SQTS). The drugs showed good results in the correction of arrhythmias. Finally, it can be concluded that the PharmaLab computational tool has resources for use in both research and teaching.

Owing to increasing emission specification, decreasing price of energy storage systems and power electronic devices, in addition to fast-developing technology, Electric Vehicles (EVs) will become a significant share of automotive market in the near future [1]. Therefore, there is a huge competition among car manufacturers to produce EVs. The final price and driving range are known as vital factors to win the competition.

Atopic dermatitis (AD) is a common, complex, multifactorial disorder of infants and children. Although the pathogenic mechanisms underlying AD are not very well understood, food allergy (FA) was first suggested as a contributory factor in 1936 (1). In this review we shall focus on the relationships between AD and FA. Symptoms occurring after contact with different foods will not be discussed. It was reported that cow's milk (CM) predisposed to the development of AD since it was demonstrated that infantile eczema occurred seven times more often in a CM-fed group than in a breast-fed one. In 1955 Glaser found that skin rashes and urticaria frequently developed in babies fed egg-white during the first 3 months of life, while the prevalence was significantly reduced when the egg-white was given only after the 6th month of life (2). In a crossover study, Atherton et al. (3) demonstrated a marked improvement of AD in 2to 8-year-old children while they were receiving an eggand CM-free diet. In particular, it was noted that 14/20 patients on that diet showed a significant improvement of the skin lesions, whereas only 1 had a favorable response when he received egg and CM in the diet. The contributory role of both CM and egg was confirmed in following studies. Sampson and McCaskill (4) evaluated 210 children in doubleblind placebo-controlled oral food challenges (DBPCFC) (many children were subjected to Luisa Businco, Matteo Ferrara and Arnaldo Cantani

Territoriality of snowy owls (Nyctea scandiaca) was investigated near Calgary, Alberta, in the winters of 1976–1977 and 1977–1978. Males appeared to be nomadic, although some individuals remained in small areas for periods of up to 17 days. Many females defended territories of 150–450 ha for periods of up to 80 days. Territories of females contained some habitats in excess of their proportion on the study area. This represents selection of habitats with high prey availability. Owls spent more time in such habitats than in resource-poor habitats within their territories. Territory size was inversely related to the proportion of stubble field and the amount of "edge" habitat bordering stubble fields, on the territories. These findings are consistent with an earlier hypothesis that the size of feeding territories is regulated to provide the territory holder with a constant level of food. Juvenile females defended larger territories than did adult females, with higher proportions of nonpreferred habitats. We ...

Managers need to understand the types of perceptions, feelings, and reactions they should elicit from personnel
under their direction. To this end, a parsimonious model is required. However, few comprehensive models
linking managerial behaviours to employee states and outcomes have been developed and tested. Accordingly,
this research articulates the importance of three critical constructs - leader–member exchange (LMX), job
satisfaction, and perceived organizational justice – and associations with emotional exhaustion, work motivation,
workplace misbehavior, and emotional intelligence as a concise and efficient model that explains the
relationships between attitudes and states within individuals, and related, important work and personal outcomes.
The model displayed a very high level of reliability and validity based on the exceptional fit of the structural
equation models across two very large samples (over 1600 participants in each study).

Abstract The lockdown triggered by the coronavirus pandemic (March– June 2020) affected not only the economy, but also the functioning of the administration, and thus procedures connected with spatial planning. Spatial planning at the local level, in accordance with the principle of subsidiarity enshrined in the Polish constitution, belongs to the so-called “commune’s own tasks” 1 . Formal spatial planning procedures in Poland, equipped with administrative, technical consulting apparatus, were subjected to stress testing during the pandemic. The crisis situation not only highlighted their weaknesses unprecedentedly, but also showed new opportunities and caused changes in conducting procedures. The discussion on issues of deliberativeness and communication in planning theory that has been going on for decades has been enriched with many new practical experiences in just a few months. Although the research regarding this period is just beginning, it is already known that the conclusions drawn from it will affect the future shape of the planning system. Various reactions of local governments to an unusual situation constitute a reservoir of diagnoses, problems and practical solutions that should be taken into account in the discussion. This paper presents the results of qualitative research conducted during the confinement regime. It is focused on the issues of self-government spatial planning units’ work organisation and connected with these changes in the shape of the consultation processes conducted. Research has focused on issues related to the organisation of work of local planning units, supporting digital technology and related changes in the shape of consultative processes.

We present a real-time speech-driven facial animation system. In this system, Gaussian Mixture Models (GMM) are employed to perform the audio-to-visual conversion. The conventional GMM-based method performs the conversion frame by frame using minimum mean square error (MMSE) estimation. The method is reasonably effective. However, discontinuities often appear in the sequences of estimated visual features. To solve this problem, we incorporate previous visual features into the conversion so that the conversion procedure is performed in the manner of a Markov chain. After audio-to-visual conversion, the estimated visual features are transformed to blendshape weights to synthesize facial animation. Experiments show that our system can accurately convert audio features into visual features. The conversion accuracy is comparable to a current state-of-the-art trajectory-based approach. Moreover, our system runs in real time and outputs high quality lip-sync animations.

Radioactive RNA was obtained from Xenopus laevis gastrula-stage embryos which had been labelled by microinjection of [3H]uridine. A 9-12-S RNA fraction was isolated by phenol extraction of whole embryos followed by sucrose gradient centrifugation of the RNA and polyacrylamide gel electrophoresis. This RNA was identified as histone mRNA on the basis of its chemical and physical properties. On polyacrylamide gels the labelled RNA could be subfractionated into different components with electrophoretic mobilities similar to those of histone mRNAs of the sea urchin. 9-12-S RNA lacked poly(A) sequences. In a protein synthesis system in vitro the RNA fraction directed the synthesis of the histones H4, H2A, H2B, H3 and, possibly, of H1 protein. The Xenopus gistone mRNA was challenged with Xenopus DNA under conditions of vast DNA excess. A cot1/2 of between 110 and 250 mol-s-1(-1) was obtained from the RNA trace curve, indicating that the histone genes were 20-50-fold reiterated in the haploid genome of the species. This value indicates that although amphibians have several embryological and morphological features in common with sea urchins, the reiteration frequency for Xenopus histone genes is closer to the value of 10-20 established for mammals than the value of 400-1000 determined for sea urchins.

The citric acid/nickel acetate composite hollow fibers were prepared by using sol-gel processing and co-electrospinning technique. The polycrystalline NiO hollow nanostructured fibers were prepared after calcination. The obtained hollow nanostructured fibers made up of 17∼25 nm nanocrystals were about 150 nm to several micrometers in outer diameter. The hollow NiO nanostructured fibers have been characterized by TG, DSC, SEM, FTIR, and XRD techniques. The results showed that the morphology of NiO hollow fibers was obviously influenced by the calcination temperature.

The methyl sulfide derivatives of cobalt bis(dicarbollide) [8,8'-(MeS)2-3,3'-Co(1,2-C2B9H10)2]-, [4,4'-(MeS)2-3,3'-Co(1,2-C2B9H10)2]- and [4,7'-(MeS)2-3,3'-Co(1,2-C2B9H10)2]- were synthesized by the reaction of CoCl2 with [10-MeS-7,8-C2B9H11]- and [9-MeS-7,8-C2B9H11]-, respectively, in strong alkaline aqueous media. The 4,4'-(rac)- and 4,7'-(meso)-isomers were separated by column chromatography on silica as the tetrabutylammonium salts. The structures of (Bu4N)[8,8'-(MeS)2-3,3'-Co(1,2-C2B9H10)2], (Bu4N)[4,4'-(MeS)2-3,3'-Co(1,2-C2B9H10)2] and (Bu4N)[4,7'-(MeS)2-3,3'-Co(1,2-C2B9H10)2] were determined by single crystal X-ray diffraction. In the solid state, the rotation of the two dicarbollide ligands with respect to each other is hampered due to formation of intramolecular CHcarb ***S(Me) hydrogen bonds between the ligands, that results in stabilization of definite rotamers - transoid- in the case of 8,8'-isomer, and gauche- in the case of 4,4'- and 4,7'-isomers. These data are in a good agreement with results of the quantum chemical calculations.

When industrial laboratory experiments are done, it is important to keep in mind the objectives of the study. This is because the experiments that will be required are critically dependent on these objectives. In order to decide what these objectives are, one needs to have a rudimentary design for the process that highlights the key issues and drivers for the economics of the process. We address this by doing a case study on a Fischer-Tropsch (FT) process. A method of synthesizing an FT flow sheet incorporating syngas generation, air separation, hydrocarbon synthesis, product workup, recycling, and reforming is presented. The impact of these unit operations on the entire FT synthesis process has been studied by turning all their material, energy, and work requirements into one variable, namely carbon efficiency. Preliminary experimental data on an FT catalyst is used to demonstrate the method. From this the effect of the H 2 :CO ratios, space velocities, and feed partial pressures in the FT synthesis loop on the overall plant carbon efficiency are investigated. The implication of the results on the further flow sheet development and experimental program is considered.

&NA; We describe a simple, effective approach to the creation of autologous tissue‐engineered cartilage in the shape of a human nipple by injecting a reverse thermosensitive polymer seeded with autologous chondrocytes in an immunocompetent porcine animal model. A biodegradable, biocompatible copolymer of polyethylene oxide and polypropylene oxide (Pluronic F‐127), which exists as a liquid below 4°C and polymerizes to a thick gel when it is exposed to physiologic temperatures (body temperatures), was used as a vehicle for chondrocyte delivery and as a scaffold to guide growth. Autologous chondrocytes isolated from porcine auricular elastic cartilage and suspended in 30% (weight/volume) Pluronic F‐127 were injected on the ventral surface of the pigs from which the cells had been isolated. A circumferential subdermal suture was used to support the contour of the implant and assist in its projection in the form of a human nipple. After 3 weeks, the skin over and surrounding the implant was tattooed to create the appearance of a human nipple‐areolar complex. As controls, an equal number of injections were made using either cells alone (not suspended in hydrogel), or hydrogel alone. After 10 weeks, all specimens were excised and examined both grossly and histologically. Before harvesting, visual inspection of the tattooed chondrocyte‐Pluronic F‐127 hydrogel implant sites revealed that they closely resembled a human female nippleareolar complex. Nodules were similar in size, shape, and texture to a human nipple at each injection site. Glistening opalescent tissue was surgically isolated from each implant site. Hematoxylin and eosin, safranine o, trichrome blue, and Verhoeff's stains of the experimental implants showed nodules with the characteristic histologic signs of elastic cartilage. Control injections of copolymer hydrogel alone exhibited no evidence of cartilage formation. Control injections of chondrocytes alone showed evidence of dissociated microscopic nodules of elastic cartilage. (Plast. Reconstr. Surg. 102: 2293, 1998.)

Preliminary data suggest drug resistance plays a major role in mantle cell lymphoma (MCL) and is linked to the aberrant expression of molecules such as Glutathion S-Transferase pi (GST pi) that catalyzes the nuclear conjugation of a broad variety of reactive electrophiles to the glutathion. We investigated in vitro the effect of the inhibition of GSTpi activity on the chemosensitivity of MCL cell lines by inhibiting the nuclear transport of GSTpi with Agaricus bisporus leptine (ABL). Methods. Four MCL cell lines (Granta, NCEB, REC and UPN1) were analyzed for GSTP1 transcript expression by RT-PCR analysis and for GSTP1 genetic Ile105Val polymorphism. The effect of ABL on the 4 MCL cell lines viability was examined using cells pre-treated with ABL (40μg/ml) for 10 h followed by treatment with various concentrations of doxorubicin (DOX), cisplatin (CDDP), cytarabin and bortezomib for 48 h. The cell viability was estimated by MTT assay repeated three times. Results. All the 4 cell lines expressed GSTPI transcript. Two of them (UPN1 and REC) were heterozygous for Ile105Val polymorphism, whereas NCEB and GRANTA were homozygous GSTP1-105Ile which has been correlated with an enzyme of high activity. DOX, CDDP, cytarabin and bortezomib have cytotoxic effects compared to non-treated cells, without any difference between the 4 MCL cell lines when considering their genetic polymorphism status. Co-administration of ABL caused a significant increasis of the cytotoxicity of CDDP and bortezomib in all cell lines (Student test: p between 0.0004 to 0.02 for CDDP; and p between 0.013 and 0.05 for velcade, depending on the cell lines). Co-administration of ABL caused an increasis of the cytotoxicity of cytarabin in 3 cell lines, the 4 th being actually tested. No influence of ABL was detected on the cytotoxic effect of DOX. The analysis of the nuclear and the cytoplasmic localizations of GSTpi is currently realized by immunohistochemistry. Conclusion. These results suggest that inhibition of the nuclear transfer of GSTpi increases in vitro the MCL sensitivity to CDDP, cytarabin and velcade but not DOX.

Untersuchungen zur Her2/neu-Amplifikation und -Expression, die im Zusammenhang mit der Entstehung von Brustkrebs und seiner Diagnostik stehen, sind fur eine zusatzliche Verfeinerung der Diagnoseparameter und damit einer Verbesserung der Therapieansatze von enormer Bedeutung. In dieser Arbeit wurden durch hochauflosende lichtmikroskopische Verfahren grundlegende Untersuchungen zu Her2/neu sowohl auf Gen-, als auch auf Proteinebene durchgefuhrt, um neue und unterstutzende Ansatze fur einen besseren Therapieerfolg bei Brustkrebspatienten zu erhalten. Eine genaue Auszahlung der Her2/neu-Genkopien mit herkommlichen Markierungsmethoden (z.B. Fluoreszenz in situ Hybridisierung) ist momentan durch die Sondengrosen und die konventionelle mikroskopische Auflosung nur unzureichend moglich. Die molekularbiologische Methode der kombinatorischen Oligonukleotid-Fluoreszenz in situ Hybridisierung in Verbindung mit sensitiver hochauflosender Lichtmikroskopie bietet aufgrund der kleinen Sonden und der verbesserten Auflosung einen neuen Ansatzpunkt der eine eindeutigere Zuordnung der einzelnen Her2/neu-Genkopien ermoglicht und somit eine genauere Auszahlung der Fluoreszenzsignale zulasst. Erstmals werden fur diese Untersuchungen Peptid-Nukleinsaure (PNA)-Oligosonden eingesetzt, da diese grose Vorteile in der Lebendzellmarkierung zeigen (z.B. Nukleasen-, Peptidasen- und Proteasenresistenz, hohere chemische Stabilitat als DNA / RNA, Anlagerung an den nativen DNA-Strang, etc.). Die Modifikation dieser kleinen Fluoreszenzsonden mit Twisted Intercalating Nucleic Acids (TINA) verbessern die Anlagerung der PNAs an den nativen DNA-Strang. Diese schonende Hybridisierung ermoglicht Ablaufe innerhalb der Genomorganisation ohne destruktive Strukturveranderung zu beobachten. Das in der Arbeit etablierte und optimierte COMBO-FISH-Protokoll fur fluoreszenzmarkierte PNA-Oligosequenzen fuhrte zu erfolgreichen Hybridisierungen mit repetitiven Zentromer- und genspezifischen Sonden. Die TINA-modifizierten-PNA-Sonden zeigten bei der Lebendzellmarkierung ebenfalls gute Hybridisierungs-Effizienzen. Weiterhin konnte man an Brustkrebszellen mit unauffalligem Genotyp die Spezifitat des Her2/neu-Sondensets bestatigen. Abschliesend konnte gezeigt werden, dass durch die Kombination hochauflosender Lokalisationsmikroskopie mit COMBO-FISH-Sonden eine effektive optische Auflosung in biologischen Praparaten bis zu einigen wenigen Nanometern erreicht werden kann, um Untersuchung von struktur-abhangigen Genomfunktionen oder Fehlfunktionen durchfuhren zu konnen. Die Etablierung der Lokalisationsmikroskopie fuhrte zu vielen biologischen Grundlagenexperimenten. Es wurden Praparate mit fluoreszenten Proteinen, organischen Farbstoffen und Alexa konjugierten Antikorpern untersucht. Diese Untersuchungen fuhrten zu einer optimalen Auswahl an Farbstoffmolekulen fur weiterfuhrende Experimente. Zusatzlich wurden unterschiedliche Markierungsmethoden verwendet und Experimente mit unterschiedlichen Einbettmedien realisiert, die Aufschluss uber das Blinkverhalten der Fluoreszenzfarbstoffe in der jeweiligen Umgebung gaben. Die durchgefuhrten Untersuchungen der Her2/neu-Rezeptorcluster und ihrer Nanostruktur auf der Zelloberflache mittels Lokalisationsmikroskopie ermoglichen eine neue Korrelation zwischen Genkopienzahl, Uberexpression und molekularer Rezeptorstrukturen. Anhand von Her2/neu Cluster-Analysen konnten klare Expressionsmuster fur unterschiedliche Brustkrebszelllinien erarbeitet werden. Diese Expressionsanalysen lassen eine klare Diskriminierung zwischen gesunden und kranken Zellen sowie zwischen Brustkrebszelllinien untereinander zu. Diese verfeinerten Erkenntnisse konnten zu einer verbesserten Diagnostik beitragen, die es beispielsweise erlaubt, eine verbesserte Prognose zum Therapieerfolg zu geben. Weiterhin wurde Her2/neu-Her3-Heterodimere untersucht, die uber Neuregulin-1 als Ligand induziert wurden. Die Dimerisierungen setzen mehrere wichtige Signaltransduktionswege des Zellwachstums und der Zelldifferenzierung in Gang. Die dadurch resultierende Deregulation der Zelle kann folglich zu einer starken Zellproliferation fuhren und somit zur Tumorgenese beitragen. Ein Versuchsansatz mit einer Vielzahl von Antikorpern gegen den selben Rezeptor konnte die Fluoreszenzsausbeute bei den Lokalisationsmessungen um ein vielfaches verbessern und kann zukunftig genutzt werden, um noch feinere Expressionsmusteranalysen durchfuhren zu konnen.

Dormant bare root rose (Rosa × hybrida ‘Las Vegas’) plants with roots dipped in a 500 ppm solution of indole-3-butyric acid (IBA) produced 50% more new roots than untreated plants. However, plants treated with 100 and 500 ppm IBA had fewer open flower buds 8 wks after potting and shorter average shoot length after 18 wks than did controls. Treatment with the potassium salt of IBA (KIBA) at 100 and 500 ppm also stimulated new root production and retarded flower bud development but did not reduce shoot length. Addition of starch-polyacrylate gel to treatment solutions counteracted the root promoting effect of IBA but not of KIBA. Gel itself also caused a reduction in average shoot length.

espanolLa biologia evolutiva es una disciplina integradora; sin embargo, en los procesos de ensenanza-aprendizaje ha ocupado espacios curriculares exiguos, que se reducen a un tema o inciso de los programas de estudio, lo que resulta insuficiente para ensenar y aprender biologia en la formacion cientifica basica, media superior y superior. Ante esa situacion, el objetivo de este escrito es plantear que en tanto los fenomenos biologicos se explican desde su funcionalidad e historia evolutiva, es necesario que los contenidos curriculares, la formacion docente y los recursos didacticos den cuenta, al mismo tiempo, de la naturaleza historica y funcional de lo vivo; solo asi podra lograrse la ensenanza y el aprendizaje del pensamiento biologico EnglishThe evolutionary biology is fundamental in the unification of the biological sciences.

Most cases of CVID occur sporadically, but familial cases do also occur and 15% of the patients with the disease have first degree relatives with IgA deficiency (IgAD). Our purpose was to study CVID association with HLA class II alleles and to ascertain whether this disease shares a common genetic background with IgAD in our population. Patients with CVID (n = 42), were typed using gene amplification and sequence‐specific oligonucleotide probing for HLA‐DRB1, DRB3, DQA1 and DQB1 loci and their typing compared with that of 96 IgAD and 334 healthy controls. We observed a positive association between non‐Asp residues at position 57 of the HLA‐DQβ chain and CVID, although much weaker than in IgAD. Further, we found an association between CVID and homozygosity for genes encoding HLA class II molecules, especially HLA‐DQ, not seen in IgAD. The data support the hypothesis that a restricted diversity of HLA class II molecules may contribute to susceptibility to CVID.

The rapid increase in renewable energy resources has resulted in the increasing need for a demand flexibility program (DFP) from industrial load resources as a solution to oversupply and peak load spikes. However, to reasonably estimate the DR potential flexibility, the load characteristics must be analyzed and potential assessment formulas must be validated. Thus, in this study, a novel method is proposed to evaluate the DR potential flexibility of industrial loads according to a process of related load-characteristic data analysis. The proposed potential-estimation model considers frequency, consistency, and DR event operation scores during designated ramp-up and ramp-down time intervals separately. A case study was conducted by considering typical cement industry process with actual power-consumption data analysis for demonstrating the test system. The results confirm that load reduction of more than half of the usual power consumption is possible if a potential score is about 0.27 in cement industry cases. Thus, the proposed method can be used as an indicator to determine how an industrial load is adequate for obtaining a DFP while suggesting meaningful implications through industrial load-resource data analysis.

A programmable micro-processor controlled interactive media based instruction delivery system using super-8 film cassettes and addressable audio tape messages has been developed in order to make available to deaf and hearing impaired learners delivery of a wide range of validated media-based instructional materials. This paper describes the prototype system, unique instructional materials authoring methods, makes comparisons with conventional computer assisted instruction (CAI) and computer managed instruction (CMI), and discusses the system use not only in instruction delivery, but in instructional materials development and validation for use in creating videodisc masters. It outlines current plans for implementing this technology in the near future.

Reimagining the Human Service Relationship, edited by Jaber F. Gubrium, Tone Alm Andreassen, and Per Koren Solvang, is an excellent collection of essays that explore and rethink the relationship between service professionals and service users. The book is divided into four sections that emphasize, first, the historical development of the human service relationship; second, service users’ shifting participation in human service relationships; third, changes in professionals’ relationships to human service; and fourth, reimagined service relationships in which equity and caring figure prominently. The chapters range across a variety of professions concerned with service and caring, including service relations with ‘‘difficult’’ users—for example, young children, the homeless, and older people with identified cognitive deficits. As Andreassen notes in Chapter Two, co-morbidity is a feature of illness for service users but is rarely addressed by the professionals responsible for care. Indeed, given the ongoing discussions in the field about the impermeability of human service silos, this collection illustrates the possibilities that exist across service divisions. The data on which the analyses are based are primarily qualitative. Some authors have been collecting data in the field of human service relationships for twenty or more years. Others are drawing on recent PhD research, at times with teams of researchers. The breadth of the research combined with the historical character of some of the data brings a depth to this volume that is unusual and certainly welcome. In this review, I will summarize the sections and focus on one chapter that stood out for me. I will explore more fully those chapters that combine qualitative data from users and professionals with the limits imposed by professional dicta and address the administrative and technological boundaries that are propelling the shifts we see in the human caring relationship today. Gubrium’s chapter ‘‘From the Iron Cage to Everyday Life’’ opens the collection. He provides a historical overview of the inside and outside of the service caring relationship. Gubrium proposes that reimagining the service relationship of both the professional and the service user collapses the traditional dichotomy of insider and outsider. The author identifies two trends challenging the traditional power of human service professionals. The first challenges expert knowledge—who knows, and what do they know? The second involves the increased involvement of service users in the human service relationship. The everyday practices of service providers and users are embedded in moment-by-moment decisions in which service policies are coordinated and moderated by front-line workers. Gubrium introduces a theme that runs throughout the volume: what does the human service relationship look like from the life world of both user and professional? Part Two takes the historically invisible perspective of the service user. This section is perhaps the most ethnographically rich. Recognizing the various strategies and manners through which service users manage this relationship not only shows their active participation but also calls into question professionals’ assertions about what works in the caring process. E. Summerson Carr’s chapter draws from an outpatient drug treatment program for homeless women entitled ‘‘Flipping the Script.’’ The chapter reveals the ongoing language work of homeless women as they learn and use the talk of the professionals working with them. Their language use is strategic and skilled, particularly in the context of evaluations of progress made by the professionals. Managing to ‘‘talk the talk’’ without necessarily following up with the ‘‘walk’’ is a learned and risky strategy the women use. Carr suggests that the women successful at flipping the therapeutic script were able to command the reason and Reviews 673

In this paper, we present a simple and accurate adaptive time-stepping algorithm for the Allen–Cahn (AC) equation. The AC equation is a nonlinear partial differential equation, which was first proposed by Allen and Cahn for antiphase boundary motion and antiphase domain coarsening. The mathematical equation is a building block for modelling many interesting interfacial phenomena such as dendritic crystal growth, multiphase fluid flows, and motion by mean curvature. The proposed adaptive time-stepping algorithm is based on the Runge–Kutta–Fehlberg method, where the local truncation error is estimated by using fourth- and fifth-order numerical schemes. Computational experiments demonstrate that the proposed time-stepping technique is efficient in multiscale computations, i.e., both the fast and slow dynamics.

Powered by the pervasive penetration of inexpensive mobile devices and relevant APP's into our daily life, QR codes have found a wide range of applications in recent years. Therefore, the processing of the images of QR codes (also referred to as QR images) is an important task. In this paper, we try to deal with the scenario wherein the QR code is printed or pasted (altogether also referred to as "posted") on the surface of a cylinder. In the scenario considered in this work, the posting need not be aligned to the axis of the cylinder. When a picture is taken on such a QR code, the picture can be seriously distorted, and thus suffers a high probability of decoding failure. In this paper, a scheme called rectification by conic segmentation (CS) is proposed to tackle this kind of problems. Experiments show that the proposed scheme is effective, in the sense that many failed trials at QR decoding become successful after the rectification.

The characteristics of Al2O3 film grown by atomic‐layer deposition as blocking layer with and without fluorine plasma treatment were investigated based on a capacitor structure of Al/Al2O3/TaON/SiO2/Si. The physical structure was studied by transmission electron microscopy, and the chemical composition of the blocking layer was analyzed by X‐ray photoelectron spectroscopy and secondary ion mass spectroscopy. Moreover, the surface roughness of the blocking layer was investigated by atomic force microscopy. Compared with a capacitor with Al2O3 blocking layer, the one with fluorinated Al2O3 displayed higher programming/erasing speeds, better endurance property and better charge retention characteristic because the fluorination could reduce excess oxygen and traps in the blocking layer, thus forming a larger barrier height at the interface between the charge‐trapping layer and the blocking layer.

ABSTRACT This study looks at the rhetorical use of history and memory in narratives about food origins in contemporary Southern cookbooks. I argue that these narratives are employed as evidence of authenticity, proof that the recipe is appropriate for performing authentic Southern identity. Using narratives of the origins of Brunswick stew as a case study, I argue that the choice to narrate either history or memory is a rhetorical strategy, suggesting that arguments for authenticity based on memory may be more convincing to contemporary Southern audiences who wish to revise, resist, or erase the Southern past. The competing narratives of the history of Brunswick stew are repeated in contemporary food histories and cookbooks as evidence of the recipe's age and authenticity, and I argue that the particular variations in the narratives reveal much about each author's definition of authentic Southern food. However, some cookbook writers choose to use personal memory as evidence of authenticity, instead of the historical origin narrative, in order to avoid relating the recipe with Old South nostalgia and the realities of slavery.

Photoluminescence performances of Pr-doped alkaline-earth titanates (Ba,Ca)TiO3 (with rich barium) prepared by a solgel technique are investigated at room temperature. A relatively strong red luminescence is observed in (Ba0.80Ca0.20)TiO3 material when Pr-BaTiO3 material does not exhibit obvious red luminescence. The phenomenon is discussed with respect to the substitute of Ca and the two-photon luminescence effect. The red luminescence is enhanced by a fast thermal treatment. The wavelength range of luminescence near red and infrared light is broadened by the same process as well. These behaviors are ascribed to the randomization of distribution of Ca and Ba at A site in ABO3 perovskite structure. The experimental results provide not only a possible way to develop new materials with pastel visual impression, but also a potential technique to modify photoluminescence properties that can be controlled by external fields because the microscopic structure of BaTiO3, such as electric domains, can be changed by electric field, temperature, and so on.

An optical arrangement for constructing wavelength-tunable spectral filters is presented that makes use of a set of dispersive polarization rotations to select wavelengths. A filter in the arrangement is initially mechanically tunable, requires no achromatic retarder, and can be further electrically tunable, switchable, or both, depending on the elements selected. Test measurements and results are presented and described. Modified arrangements with additional retarder(s) or liquid-crystal polarization rotator(s) are suggested and discussed.

Em um ambiente de transformação enxuta, as mudanças nos processos devem acontecer de forma rápida e assertiva. Vários aspectos devem ser considerados para a garantia da entrega de um processo com alto nível de produtividade, dentre eles a eergonomia, a interação entre homem e máquina, os fluxos de entrada e saída de materiais, bem como os resíduos gerados pelo processo. O presente estudo de caso mostra a aplicação da simulação de processos (mockup) para validação da adaptação de um processo de manufatura tradicional para o modelo enxuta, por meio de estudo de caso aplicado em linha de montagem de equipamentos agrícolas. Os resultados são amplamente expressivos, chegando a alcançar aumento na produtividade na ordem de 100%, com significativa redução de área produtiva e melhoria nos aspectos ergonômicos dos operadores.

Abstract The aim of this review was to summarise and evaluate the available literature on the effectiveness of complementary and alternative medicine (CAM) for the management of low back pain (LBP). Papers were included in the literature search if they were randomised controlled trials (RCTs) assessing the effectiveness of a CAM in the treatment of LBP. Quality was assessed using the van Tulder methodological score. Recent systematic reviews carried out investigating chiropractic, osteopathy, acupuncture, and massage have found them to be useful therapies in the management of LBP, and papers in these areas were, therefore, excluded from this review. Nine RCTs were identified; methodological quality was moderate. While RCTs for those therapies which were investigated produced encouraging results, including yoga, homeopathy, herbal therapies, and hypnotherathy, small sample sizes and the low number of trials investigating individual therapies prevents definite conclusions being drawn. The available literature suggests that these forms of CAM are worth investigating as an approach to relieving LBP. Future work should be to increase the evidence base of these therapies through larger, well-designed RCTs.

The rheological behavior of the industrialized acerola juice was studied at different soluble solids concentrations 4, 7, 10, 13 and 16oBrix and temperatures from 5 to 85oC, using a concentric cylinder rheometer. Rheograms were fitted according to the following models: Ostwald-de Waele or Power Law, Herschel-Bulkley, Mizrahi & Berk and Casson. The best results were obtained using the Herschel-Bulkley model and the low values presented by the behavior index (0,338 < nhb < 0,759) confirm the pseudoplastic behavior of the acerola juice. An equation similar to the Arrhenius one (ha = h0 exp(Eat/RT)) described the effect of the temperature on the acerola juice. The results also showed that the activation energy decreases with the increasing in juice concentration, varying from 3.50kcal/gmol (4oBrix) to 1.79kcal/gmol (16oBrix). Potential and exponential models were tested considering the apparent viscosity data as a function of the soluble solids concentrations. For this purpose, the potential model showed the best performance.

Islam is a religon that very upholds of prestige and dignity every person without discriminate of gender, both men and women. However, as time goes by, the sculpture of religion becomes multi-commentation for praising certain gender and humiliating others. The gender inequality of social role is considered as divine creation, it means that everything comes from God. In contrast to the perception of feminist who considers the inequality as a social construction. The gender inequality of social role is still retaining under excuse of religion doctrine. Religion is involved to preserve conditions in which women do not consider themselves equal to men. It is possible that behind of this theological "consciousness" occurs anthropological manipulation that aims to establish a patriarchal structure, which generally harms women and benefits only certain classes of society. Looking at this paradigm shift, Amina Wadud is trying to boost the understanding that has deviated far from the Al Qur'an award on women.

Rhizobium fredii USDA205 cells were cultured in the presence of 4',5,7-trihydroxyflavone (apigenin), a compound that has been shown to induce the nod genes and other symbiosis-related genes in R. fredii. The cell-associated polysaccharides were then extracted with hot phenol/water, separated by repetitive gel filtration chromatography, and analyzed by polyacrylamide gel electrophoresis, nuclear magnetic resonance spectrometry, high-performance anion-exchange chromatography, and gas chromatography. These analyses showed that apigenin effects a modulation in the production of some cell-associated bacterial polysaccharides: 1) The production of a glucan is severely attenuated; 2) the lipopolysaccharide O antigen is modified in composition and M(r) distribution; and 3) the ratio of two extracted polysaccharides, which are structurally analogous to group II K antigens (capsular polysaccharides), is altered. Similar effects resulted from the inclusion of host plant root extract in the growth medium.

Grinding process is an energy intensive process in the sense that, it requires a larger amount of energy per unit of volume of material removal compared to other metal cutting processes. In this case, effects on the ground workpiece in terms of induced residual stresses and metallurgical changes due to heat generated play an important role on the lifetime of parts in their mechanism. In order to investigate effects on the workpiece during external cylindrical grinding process, a new analytical approach is firstly developed to model the action of the grinding wheel as a heat flux, which moves along the workpiece surface. The value and the shape of the heat flux entering the workpiece are directly identified. Based on the established model, numerical simulations are performed to predict temperature, cooling and its effects on residual stress distribution in the ground near surface.

An algorithm for deriving a spectrum of void sizes from two-dimensional high-resolution numerical simulations of gravitational clustering is tested, and it is verified that it produces the correct results where those results can be anticipated. The method is used to study the growth of voids as clustering proceeds. It is found that the most stable indicator of the characteristic void 'size' in the simulations is the mean fractional area covered by voids of diameter d, in a density field smoothed at its correlation length. Very accurate scaling behavior is found in power-law numerical models as they evolve. Eventually, this scaling breaks down as the nonlinearity reaches larger scales. It is shown that this breakdown is a manifestation of the undesirable effect of boundary conditions on simulations, even with the very large dynamic range possible here. A simple criterion is suggested for deciding when simulations with modest large-scale power may systematically underestimate the frequency of larger voids.

Brain tumors pose a particular challenge to molecular oncology. Many different tumor entities develop in the nervous system and some of them appear to follow distinct pathogenic routes. Molecular genetic alterations have increasingly been reported in nervous system neoplasms. However, a considerable number of affected genes remain to be identified. We present here a comprehensive allelotype analysis of 466 nervous system tumors based on loss of heterozygosity (LOH) studies with 129 microsatellite markers that span the genome. Specific alterations of the EGFR, CDK4, CDKN2A, TP53, DMBT1, NF2, and PTEN genes were analyzed in addition. Our data point to several novel genetic loci associated with brain tumor development, demonstrate relationships between molecular changes and histopathological features, and further expand the concept of molecular tumor variants in neuro-oncology. This catalogue may provide a valuable framework for future studies to delineate molecular pathways in many types of human central nervous system tumors.
