This study focuses on the spatio-temporal analysis of rainfall variability, trend patterns, and projected changes using GCM CCSM4 for RCP4.5 and RCP8.5 in Khyber Pakhtunkhwa. The historical rainfall variability (1971–2018), trend, and magnitude were assessed using Mann–Kendall and Spearman's Rho. In addition, to downscale GCMs data of precipitation at the regional level of Khyber Pakhtunkhwa, SDSM conditional sub-model was applied. The monthly Mann–Kendall and Spearman's Rho trend test results revealed that most of the meteorological stations located in the northeastern mountains recorded decreasing trend while Parachinar observed an increasing trend in almost all months except December. The trend results for seasonal rainfall showed a decreasing trend in winter, spring, and summer in the north and northeastern parts of Khyber Pakhtunkhwa whereas an increasing trend was observed in all seasons at Parachinar. The RCP4.5 projections depicted an increase in precipitation especially in the monsoon-dominating regions in comparison to the western disturbances, while decreasing rainfall projection was observed in RCP8.5. The projections for the summer and winter seasons depicted an increasing trend till the mid-century but in the latter half, a decline is registered. Such seasonal changes may initially cause flooding followed by drought, which calls for effective water management strategies.

Purpose - By using the World Bank's new poverty data that are based on the most recent International Comparison Program report, this research aims to revisit the response of poverty rate to increase in real gross domestic product (GDP) per capita. Design/methodology/approach - The response is summarized in terms of elasticity of poverty with respect to real GDP per capita, which is the ratio of annual percentage fall in poverty rate to annual percentage increase in real GDP per capita. The main calculations are done for the entire group of less-developed countries (LDCs), poverty-dense South Asia region, and India, which probably has the highest poverty rate. The periods studied are 1981-1990, 1990-1999, and 1999-2005. The calculations are done for four different poverty measures. Findings - Five major points are noted. First, the elasticities generally show a declining tendency over the period, indicating that poverty-reducing impact of income growth has been weakening. Second, the elasticities show huge differences across the poverty lines, and generally decline with higher poverty lines. Third, while global elasticities for $1.00 poverty line bear some resemblance to those reported or used by many scholars, elasticities for $2.00 and 2.50 poverty rates are dramatically lower, and reinforce the view that many influential estimates show the effect of income growth on poverty to be much higher than the data indicate. Fourth, elasticities for poverty-dense South Asia are again seen to be much lower than those for the entire LDC group. Fifth, for India, where $2.00 and 2.50 poverty rates are higher than even in Sub-Saharan Africa, the elasticities are extremely low and have been declining despite an acceleration in income growth. The overall implication seems to be that income growth has generally been less pro-poor during the globalization era of the 1990s and the 2000s than during the 1980s. In particular, income growth in India seems to have had an extremely small impact on poverty, and that impact, notably for $1.00 and 1.25 poverty lines, has been declining. Originality/value - First, although there is a vast literature on growth elasticities of poverty, this seems to be the first study that uses World Bank's new poverty data to judge the impact of income growth on poverty. Second, this is the only study that directly estimates and compares elasticities for the four poverty lines of $1.00, 1.25, 2.00, and 2.50, and shows large differences in the elasticities for different poverty lines. Third, this is probably the only work that compares elasticities for the 1980s, 1990s, and the 2000s. Fourth, although some indication of very low elasticities for South Asia and India does exist in a recent study, $2.50 elasticities reported in the present work for India, and even South Asia, should constitute an eye-opener for scholars, policy-makers, and international organizations in regard to the potential role of income growth in poverty reduction. Fifth, the observed decline in most elasticities during the 1990s and 2000s, as compared with the 1980s, despite higher income levels and growth rates, may shed light on the likely role of globalization in reducing poverty.

Objective: Dyslipidemia is prevalent in adults living with type 1 diabetes, and it can worsen the presentation of microvascular complications such as retinopathy. This study aims to identify the pattern coupled with the frequency of dyslipidemia in diabetic adults who followed up at different clinics in King Abdulaziz Medical City, Riyadh, and evaluate the associations with demographic and clinical characteristics. Methods: A cross-sectional, retrospective chart review study of 514 adults with type 1 diabetes was conducted in a tertiary health care facility in the central region of Saudi Arabia. Demographics were retrieved by using the implemented electronic medical records. Fasting lipid profile, glycated hemoglobin (HbA1c), and thyroid-stimulating hormone (TSH) levels were checked for all subjects. Results: Five hundred and fourteen (514) subjects aged 18-65 years were studied (mean age: 26.1 ± 7.1 years). There were 318 (62%) females in the sample, and their mean age was significantly different from the mean age of males (p = 0.01). The mean duration of having diabetes was 12.8 ± 6.9 years. The prevalence of lipid abnormalities included abnormal low-density lipoprotein (LDL) (70%), hypercholesterolemia (23%), abnormal high-density lipoprotein (HDL) (8%), and hypertriglyceridemia (5%). Abnormal HDL was significantly higher in males than in females (p=<0.001). There were no statistically significant differences in the prevalence of other lipid abnormalities between the two genders and the age group < or ≥ 25 years. There was no statistically significant difference in the mean of the tested lipids levels between the two genders. One hundred and forty-three (143) (27.8%) patients had more than one abnormal lipid condition. A statistically significant difference was observed in the mean HbA1c between males and females (p=0.001). Otherwise, there was no significant association of lipid abnormalities with gender, age, diabetes duration, and weight. Conclusion: The most prevalent lipid abnormality was high LDL cholesterol. Nearly a third of the tested individuals had more than one lipid abnormality. Furthermore, poor glycemic control was linked to abnormal lipid profiles. Consequently, local programs must aim to screen and intervene early to delay and prevent future severe vascular complications related to non-treated dyslipidemia.

Compression of higher order optical solitons in fibers with anomalous dispersion decreasing along their length is investigated. We demonstrate high-quality compression of pulses with initial soliton order 1<N<2 achieving compression factors over 50, using a fiber length equal to approximately one soliton period. This pulse compression technique has significant advantages over the widely reported adiabatic and soliton-effect compression techniques.

Nous introduisons le concept de cicatrisation en milieu humide pour repousser les limites d’une greffe composée de pulpe. Dans cette etude retrospective, nous avons constaté le succès d’une greffe composée de pulpe par pansement crème maintenant le milieu humide, qui a montré le maintien d’une humidité adequate pour une cicatrisation optimale par application fréquente de la crème sans la nécessité d’un pansement secondaire. Nous avons revu les résultats de 60 amputations de pulpe sur 56 patients consécutifs sur une période de 3 ans et 3 mois. Quarante deux pulpes (70%) ont complètement survécu et 18 (30%) ont échoué. Douze de 15 doigts (80%) chez les patients âgés de moins de 15 ans et 30 sur 45 (66,7%) parmi ceux de 16 ans et au dessus ont survécu complètement. Nous pensons que l’utilisation d’une crème antibiotique pour maintenir un millieu humide a été un facteur important pour améliorer la survie des greffons composites.

The polymerizable monomer encapsulating CdTe quantum dot was synthesized by the electrostatic reaction. Then CdTe/PMMA was successfully obtained via free radical bulk copolymerization with the mixture of the polymerizable monomer and methyl methacrylate, which emit green light under visible light. The structure and optical properties of CdTe/PMMA were investigated by Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Uv-vis absorption spectrum, and fluorescence spectrum, respectively. The results indicated that the CdTe/PMMA emit green light under ultraviolet and visible region (380-500nm). When the polymerizable monomer encapsulating CdTe quantum dot was 1.2%, the fluorescence quantum yield of CdTe/PMMA was 7.1%.

The objective of this study was to test the use of plant volatiles as a simple, safe and effective technology for postharvest insect pest control. Specifically, the fumigant action of the three local plant essential oils, namely Cinnamomum sp. (Lauraceae), Eucalyptus sp. (Myrtaceae), and Salvia officinalis L. (Lamiaceae), were tested against Acanthoscelides obtectus (Coleoptera: Chrysomelidae), which has recently become a major pest of dry beans in Egypt. To test the efficacy of each oil, 7 μl was added to a piece of filter paper at various concentrations (4–11 %) and then placed inside a perforated gelatin capsule. This technique was used to eliminate direct contact between the volatile oils and stored beans (to avoid any adverse effects to beans). At 48 h post-treatment, adult insect mortality was significantly increased for all tested oils relative to the untreated control. Based on probit analysis at 48 h post-treatment, the Cinnamomum sp. essential oil was the most effective (LC50 = 4.55 %; 4.23–4.89 %). Eucalyptus sp. (LC50 = 7.47 %; 7.15–7.80 %) and S. officinalis (LC50 = 7.57 %; 7.20–7.96 %) had similar but lower efficacies. The main component in Cinnamomum sp. oil was (E)-cinnamaldehyde (a phenylpropene), while in Eucalyptus sp. oil it was 1,8-cineole (eucalyptol), and in S. officinalis oil they were eucalyptol and camphor (terpenoids). The fumigant activity of the tested oils is attributable to their richness in volatile phenylpropene and terpenoids. The gelatin capsule is a simple yet effective technique that could be used in integrated pest management programmes for postharvest treatments, but further testing is required, especially in small-to-medium storage environments.

The parallel measurement of transcriptome and proteome revealed unmatched profiles. Since proteomic analysis is more expensive and challenging than transcriptomic analysis, the question of how to use messenger RNA (mRNA) expression data to predict protein level is extremely important. Here, we comprehensively evaluated 13 machine learning models on inferring protein expression levels using RNA expression profile. A total of 20 proteogenomic datasets from three mainstream proteomic platforms with >2500 samples of 13 human tissues were collected for model evaluation. Our results highlighted that the appropriate feature selection methods combined with classical machine learning models could achieve excellent predictive performance. The voting ensemble model outperformed other candidate models across datasets. Adding the mRNA proxy model to the regression model further improved the prediction performance. The dataset and gene characteristics could affect the prediction performance. Finally, we applied the model to the brain transcriptome of cerebral cortex regions to infer the protein profile for better understanding the functional characteristics of the brain regions. This benchmarking work not only provides useful hints on the inherent correlation between transcriptome and proteome, but also has practical value of the transcriptome-based prediction of protein expression levels.

Evaluation of noise in outdoor entertainment spaces is a topic of interest in our communities . Noise from outdoor entertainment spaces has turned into an unwanted activity in rural communities due to high levels sound pressure from music events and crowd noise. There are numerous complaints from neighbors or neighborhood associations pertaining noise pollution around areas near these spaces. For this case study, field noise measurements were conducted in a winery for a regular concert season. Evaluation of the noise predictions using SoundPlan 4.0 for the winery venue and for a Glamping (“luxurious camping”) venue are the main focus of this study. The paper aims to determine a correlation between field noise measurements, methodology from ISO 9613-2:1996 Standard “Attenuation of sound during propagation outdoors,” and noise prediction results using SoundPlan 4.0 computer modeling software.

T he past three decades have seen remarkable progress in the development of effective antihypertensive agents. In no other area of drug research, except perhaps the antibacterials, has there been such notable success. The availability of several new classes of antihypertensive agents has allowed for effective control of hypertension without some of the serious side effects, including mental changes and postural hypotension, that were seen with older agents. Currently available antihypertensive agents may be classified into two groups depending on whether they act by decreasing cardiac output or by lowering the peripheral vascular resistance (Table 1). The most important agents that act primarily by decreasing cardiac output are the �3-adrenergic antagonists. Agents that act primarily to reduce peripheral vascular resistance include the a-adrenergic blocking agents, the central a-adrenergic inhibitors, the direct smooth muscle relaxants, and the angiotensin-converting enzyme inhibitor captopril. Calcium inhibitors are listed in Table 1 as direct smooth muscle relaxants, although verapamil and diltiazem also slow intracardiac conduction and may decrease heart rate. While not yet approved as antihypertensive agents in this country, they are commonly used for this purpose. Diuretics decrease both cardiac output and peripheral resistance. 13-ADRENERGIC ANTAGONISTS

Conclusions 1. Addition to blood of 100 μg/ml of hydrocortisone or of 0.1 to 10 g/ml of prochlorperazine results in inhibition of leucocyte migration. Addition of both compounds together results in less inhibition than is obtained with either compound alone. 2. Reserpine at concentrations of 0.1 μg/ml to 100 μg/ml is less inhibiting to leucocyte migration than is prochlorperazine. Addition of both reserpine and hydrocortisone to blood results in less inhibition to leucocyte migration than when hydrocortisone alone is added. 3. Thorazine at concentrations of 0.001 μg/ml to 1 μg/ml is inhibitory to leucocyte migration. Addition of both thorazine and hydrocortisone to blood, results in less inhibition to leucocyte migration than when hydrocortisone alone is added.

Cutaneous cylindroma is an adnexal tumour with apocrine differentiation. A predisposition to multiple cylindromas is seen in patients with Brooke–Spiegler syndrome, who carry germline mutations in the tumour suppressor gene CYLD. Previous studies of inherited cylindromas have highlighted the frequent presence of bi‐allelic truncating CYLD mutations as a recurrent driver mutation. We have previously shown that sporadic cylindromas express either MYB–NFIB fusion transcripts or show evidence of MYB activation in the absence of such fusions. Here, we investigated inherited cylindromas from several families with germline CYLD mutations for the presence of MYB activation. Strikingly, none of the inherited CYLD‐defective (n = 23) tumours expressed MYB–NFIB fusion transcripts. However, MYB expression was increased in the majority of tumours (69%) and global gene expression analysis revealed that well‐established MYB target genes were up‐regulated in CYLD‐defective tumours. Moreover, knock‐down of MYB expression caused a significant reduction in cylindroma cell proliferation, suggesting that MYB is also a key player and oncogenic driver in inherited cylindromas. Taken together, our findings suggest molecular heterogeneity in the pathogenesis of sporadic and inherited cutaneous cylindromas, with convergence on MYB activation. © 2016 The Authors.

In the 1960s a left-wing movement emerged in the United States that not only crusaded against social and economic exploitation, but also confronted the problem of personal alienation in everyday life. These new radicals - young, white, raised in relative affluence - struggled for peace, equality and social justice. Their struggle was cultural as well as political, a search for meaning and authenticity that marked a new phase in the long history of American radicalism. This text tells the story of the new left, illustrating the spiritual dimension of student activism. The author provides an account of how this radical movement developed in a campus environment - the University of Texas at Austin, one of the most important new left centres in the United States - while linking local developments to the national scene. Rossinow argues that the movement was deeply entwined with a personal quest for authenticity. This search reached a fever pitch during the decades of the 1950s, 1960s and 1970s as a moral imperative that intersected with the struggle for social justice. He shows the continuity between the religious search for meaning in the 1950s and the secular search for wholeness and realness in the new left and the counterculture. Rossinow also demonstrates the pivotal role played by the civil rights movement in forging these connections in the minds of white American youth and explains the new left's role as a force acting on its own to foment rebellion in white America. This study links the diverse strands of radical movements, from women's liberation to civil rights. Rossinow revises traditional images of radicalism and offers fresh insights on the gendered nature of the search for authenticity, and the reaction of feminists to issues of masculinity among radical men.

We address one-sided stopping rules for clinical trials, or more generally, drug development programs, from a decision-theoretic point of view. If efficacy results are sufficiently negative then the trial will be stopped. But regardless of how positive the efficacy results are, the trial will continue in order to demonstrate safety. We show how sequential decisions should be made by a pharmaceutical company attempting to maximize its expected profits.

The bootstrap in ATSC 3.0 is expected to act as a universal wake-up signal for various wireless systems in addition to broadcast network. However, the signaling decoding performance of the standardized bootstrap degrades significantly in channels of fast time-variation and strong multipath. Furthermore, part of available bandwidth is reserved to ensure the compatibility with mobile communication network (MCN), which puts a limitation on the performance improvement. In this paper, to make the best of the available bandwidth, we introduce the bandwidth-concerned version information to enable an adaptive bandwidth configuration for the proposed bootstrap. Moreover, a 2-D signaling scheme is used to increase signaling capacity by selecting different gold sequences in frequency domain (FD) and simultaneously applying cyclic shift in time domain (TD). At the receiver side, we first provide improved estimators of symbol timing offset (STO) and fine frequency offset (FFO) for the bootstrap with special TD structure. Meanwhile, a learning-based binary classifier taking the output of STO estimator as training data is provided to generate an SNR-independent threshold for spectrum sensing without requiring the knowledge of channel conditions nor noise estimator. Afterwards, an inverse fast Fourier transform (IFFT)-based algorithm is used to decode FD signaling in the presence of unknown TD signaling, which allows 3-bit higher signaling capacity. Numerical analysis and simulation results demonstrate that the proposed adaptive bootstrap design as well as corresponding receiver algorithms significantly outperform the standardized one in terms of synchronization, detection and signaling decoding.

The relative thermal protection offered by a series of halogenated vinyl polymers is discussed in terms of the usual modes of energy attenuation and dissipation, such as reflection, endothermic decomposition, etc. It is shown that none of these modes is so overwhelming that it alone can account for the relative thermal protection offered by these polymers.

Because of the narrow space and blurred vision during the process of the dam construction, collision between the equipments is easy to happen, so it is necessary to research and develop an impeccable anti-collision system. This anti-collision system uses GPS, high-speed data acquisition card etcetera to collect data, then transfers the data to control center. Control center adopts reasonable anti-collision algorithm model to dispose the data and provides dependable and reasonable alarm information to remind operators to take some related-operations. Finally, the collision during the dam construction is avoided and the problem of the prediction of the collision between the different movement of the equipments is solved.

We review recent results on high-power, high-efficiency two-dimensional vertical-cavity surface-emitting laser (VCSEL) arrays emitting around 980nm. Selectively oxidized, bottom-emitting single VCSEL emitters with 51% power conversion efficiency were developed as the basic building block of these arrays. More than 230W of continuous-wave (CW) power is demonstrated from a ~5mm x 5mm array chip. In quasi-CW mode, smaller array chips exhibit 100W output power, corresponding to more than 3.5kW/cm2 of power density. High-brightness arrays have also been developed for pumping fiber lasers, delivering a fiber output power of 40W. We show that many of the advantages of low-power single VCSEL devices such as reliability, wavelength stability, low-divergence circular beam, and low-cost manufacturing are preserved for these high-power arrays. VCSELs thus offer an attractive alternative to the dominant edge-emitter technology for many applications requiring compact high-power laser sources.

Se presentan noticias de 59 plateros aragoneses que están documentados en Madrid, alcanzando muchos de ellos la aprobación como maestros. De varios se conocen piezas con su marca. La mayoría fueron plateros de oro que era una facultad menos desarrollada que la de plata en Zaragoza —de donde procede la mayoría de los relacionados— y en otras platerías de Aragón. Las noticias provienen sobre todo del archivo del Colegio Congregación de San Eloy de artífices plateros de Madrid.

In the first place, an improvement was made on crossover and mutation of adaptive genetic algorithm (AGA) to let the crossover probability and mutation probability adapt nonlinearly. Then a comparison was made between Improved adaptive genetic algorithm (IAGA) and adaptive genetic algorithm (AGA) in segmentation time and adaptive function curve. The results indicated that IAGA can give attention to the main information of experiment images. And much less time was used by the algorithm. The process of searching for global optimum also became more stable than AGA.

This article presents the results of a methodological analysis of the digital sociological method of the Internet forum, that is, the study of thematic group discussions on the Internet, and compares the findings reached while studying the motives of the family choice of online schools in high school. Motives were studied in two ways by questioning students of online schools and by analyzing the parent forum about online schools on the Internet. Sociological information was processed in specialized computer text analysis programs. It has been established that the digital empirical technology “Internet forum” refers to the methods of document analysis and is related to the focus group. The Internet forum is relevant to the study of the educational way of a person, since the lists of arguments in favor of online education, received from questionnaires and group discussions on the Internet, almost coincided in content and frequency of occurrence of positions. The “Internet forum” method turned out to be complementary to the questionnaire and clarified some controversial collisions. The findings speak for the need to develop digital methods of sociological research, actively use the analysis of discussions on the Internet and online questioning to study educational problems and other topics.

In every year, the volume of municipal sewage has been increased due to increasing of population in Malaysia. The operation of municipal treatment should be gone for the larger scales for operation and disposal. The operation, the pre-treatment plant, post treatment plant until the suspended solid can be disposed to landfill or do some burning process to gain the methane gas towards to renewable energy. It has to meet the requirement by Department of Environment (DOE), which is by removing at least 90% of water from the suspended solid, focusing on the municipal sewage treatment. The wastewater industries need to have another alternative solution to for the time reduction of the drying process from the existing dewatering instruments or may have the new concept of the devices, which can easily help to remove the water from the suspended solid. Based on the pilot study from the industry, the dewatering bag as their chosen for the dewatering instrument. It is because of its huge of benefit such as cost. By designing a new portable dewatering device that will supply hot air to support the dewatering bag, so it will not only depends on natural heating element (sun), as a vital problem that have to be settled. So this paper presents the pilot data finding by comparing two dewatering bag, one by using the propose Universal Compress Air Fit (UCAF) and another one without it in real application. UCAF itself that supply hot air to the sludge can helps the sludge to dry 30% faster than usual.

A wideband Frequency Selective Surfaces (FSS) which is used as a superstrate for a patch antenna to form a high-gain resonant cavity antenna is presented. This FSS consists of two metal structures separated by a substrate in the middle. It exhibits a wide stop-band in the 60GHz band. Further a panel of this FSS is implemented as a superstrate for antenna gain enhancement. It is observed that a broadband gain enhancement of 5.9dB with variations less than 2dB throughout the operating band is obtained.

Introduction: Restrictive cardiomyopathy is rare and difficult illness to treat especially in the pediatric population. The purpose of our study is to demonstrate that a heterotopic heart transplantation or a mechanical assist devices as a bridge to orthotopic heart transplantation are viable successful options for these patients. Methods: We conducted Human Subjects IRB approved retrospective chart review of all pediatric patients who received a cardiac transplant and/or a mechanical assist device at our institution for the diagnosis of restrictive cardiomyopathy. We evaluated patient demographics including: gender, age, NYHA Class, ethnicity, pre-transplant medications, height and weight. We also evaluated laboratory values (pre-operative transplant heart catheterization, chest x ray, serologies), type of mechanical assist device placed, type of heart transplant (heterotopic vs orthotopic) and survival. Results: We have performed over 840 adult and pediatric cardiac transplants since 1979 and placed over 300 mechanical assist devices since 1985 in adults and children. We identified 3 pediatric patients treated for restrictive cardiomyopathy with heart transplantation and/or mechanical assist devices. Two of the patients were male and one was female. The patients ranged in age from 7 15 years at presentation. One child presented to us at 9 years, initially diagnosed at infancy with restrictive cardiomyopathy and incessant superior ventricular tachycardia. The other two children were noted to have progressive disease up to 4 years prior to referral. Two of the children had elevated pulmonary artery pressures on presentation: 70/36; 60/30 and a mean of 48; 44 respectively. Both were placed on multiple inotropic therapy including: dobutamine and dopamine. One of the two was also placed on norepinephrine and milrinone and the other on lidocaine. One child developed fulminant hepatic failure with a total bilirubin 15.2, direct bilirubin 6.3, ammonia 59, and AST 408, borderline renal failure with a creatinine of 1.5, and hyponatremia (Na 129) and the other child developed cardiogenic shock, acute renal failure and acute pulmonary edema. Each child then had a BiVentricular Assist Device (BiVAD) placed. Both children improved on the device and were bridge to orthotopic heart transplantation. The third child presented with a pulmonary artery pressure 85/53; mean 60. He was found to have a normal right ventricle and no signs or symptoms of multi-organ failure. He was admitted, his pulmonary artery pressures were too high to sustain an orthotopic heart transplant and he received a heterotopic heart transplant. All three children are currently alive. The child who received a heterotopic heart transplant is now alive 12 years after transplant and the other two patients are also alive surviving; 2.5 and 9.5 years after orthotopic heart transplant. Conclusions: Restrictive Cardiomyopathy is a rare diagnosis especially in children. For those children who fail medical therapy, heart transplantation is an option. If multi-organ system failure is present, we recommend a BiVAD as a bridge to orthotopic heart transplantation. For those children with extremely elevated pulmonary pressures who cannot tolerate an orthotopic heart transplant and no evidence of multi-organ system failure, we recommend a heterotopic heart transplant.

This issue of Constitutional Court Review (CCR) was born at a time when 'social distancing' was a technical term with currency only among specialists in public health circles. In August 2019, our annual conference was held over two days in which a fascinating array of papers was discussed and honed — face-to-face — by participants united in the common enterprise of engaging in-depth with the work of the Constitutional Court of South Africa. Backward looking in one sense, this journal reflects on recent jurisprudence of the Court and its development over time. In so doing, scholars play a critical role in the constitutional schema that holds the Court to account for its reasoning and decisions. In another sense, the journal is forward-looking, revealing alternate paths not taken or engaging with issues that inevitably will come before the Court. While the interplay of past, present and future is perhaps characteristic of the legal enterprise as a whole, it is of particular value to the constitutional project that aims to transform South African society fundamentally.

Treatment of skin with the chemical carcinogen 7,12-dimethylbenz[a]anthracene (DMBA), which reduces the density of epidermal class II MHC-expressing Langerhans cells (LC), enhances its survival when transplanted onto histoincompatible hosts. We have examined the ability of T lymphocytes which reject DMBA-treated skin to lyse P388D1 cells expressing either only class I or class I and II antigens. Lymphocytes isolated from solvent-treated grafts showed greater cytotoxicity for the targets expressing both antigens, indicating that some of these lymphocytes were specific for class II MHC antigens. In contrast, lymphocytes isolated from carcinogen-treated grafts lysed both targets similarly and hence did not contain any cells specific for class II MHC antigens. Anti-class I MHC antibody blocked cytotoxicity by both leukocyte populations to similar extents, but anti-class II MHC antibodies preferentially blocked T cells isolated from the solvent-treated grafts. There was no difference in the phenotype of the cytotoxic cells isolated from solvent- and carcinogen-treated grafts. Thus, whereas solvent-treated skin grafts are rejected by T cells specific for class I and II MHC antigens, DMBA-treated skin grafts are only rejected by class I MHC-specific T cells which may account for the enhanced survival of the carcinogen-treated grafts.

The SPI appears to be a rather sensitive instrument which may prove useful in the screening of clients and patients and in the evaluation of psychiatric programs. Subscales seem sensitive to scoring trends among various patient and non-patient groups. Several additional validity and reliability studies are currently underway.

For the purpose of assembling metal particles on a nano- or microscale, in a previous investigation the authors had succeeded in extracting magnetic clusters from an intelligent fluid responsive to a magnetic field. The clusters are shaped like rods or needles and range from macroscopic to microscopic in size. In the present paper, a method for producing silicon rubber that contains the magnetic clusters is presented and its magnetic, mechanical, and physical properties are discussed. This new material shows superpara and anisotropic magnetization. In addition, the tensile strain of the material in relation to normal stress changes due to the existence of the magnetic clusters is studied. This material can be used in engineering applications.

The mean serum levels of beta-carotene and vitamin A in a multivariate analysis of data from 64 histologically confirmed male lung cancer cases were statistically significantly lower than those from 63 randomly selected male hospital controls, who were admitted for small surgical operations (p values for both beta-carotene and vitamin A less than 0.001). The mean serum levels of zinc were not statistically significantly different between cases and controls (p = 0.10). The levels of beta-carotene, vitamin A, or zinc were not statistically significantly influenced by either the extent of the cancer (p = 0.45) or the cancer cell type (p = 0.06). The possible biological significance of these findings is discussed briefly.

Synthesis and bioassay of about 65 analogs of substance P (SP) over five years yielded the antagonist [D-Arg1,D-Trp7,9,Leu11]-SP, which was named Spantide, and which was used by many investigators as a "tool". Spantide served as a reference antagonist for the design of 47 new peptides toward the goal of more potent inhibitors. Designs emphasized analogs with D-Trp7, D-Trp9, D-Trp10, D-pClPhe10, Nle11, Leu11, Ile11 and Met11, etc. Twenty-one/47 antagonists were superior in potency to that of Spantide, the best was [D-Arg1,D-Na1(5), D-Trp7,9,Nle11]-SP which required a 255-fold increase in SP concentration to give 50% of the maximum response at a concentration of 10(-5)M of the antagonist; this potency is ca. 5 times that of Spantide. For certain, but not all pairs of undecapeptides and truncated analogs, the undecapeptides may be significantly more potent than the truncated counterparts.

Ejaculation disorders in diabetic men are most frequently caused by retrograde ejaculation resulting from a damage of the sympathetic nerves at the level of the bladder neck. This results in incomplete or complete emission failure because of insufficient sperm transport. Diabetic ejaculatory sterility can be treated with anticholinergic drugs. The reported case shows that as a result of its antihistaminic and anticholinergic properties, brompheniramine can be successfully used in the treatment of men with diabetic ejaculatory sterility, particularly in patients with incomplete emission failure.

Melanoma is a very aggressive and highly angiogenic tumor in which standard treatments have had only limited success. Patients with advanced disease have a 5-year survival rate of 5%. In search for alternatives, we identified a natural product extracted from the fungus Aspergillus niger, termed ACTIBIND, that inhibits tumor growth and metastasis of melanoma in vivo. ACTIBIND, a T2 RNase, exerts antitumorigenic and antiangiogenic activities by competing with the angiogenic factor angiogenin (itself an RNase homologue). Thus, there was decreased expression and activity of the matrix metalloproteinase 2 in melanoma and vascular endothelial cells, decreased vascularization, and increased tumor cell apoptosis in vivo. ACTIBIND significantly inhibited angiogenesis in an in vivo angiogenesis assay with sponges containing angiogenin. In vitro, ACTIBIND was internalized by both melanoma and human umbilical vein endothelial cells, reached the cell nuclei, and inhibited the activity of angiogenin response elements in a dose-dependent manner. Collectively, our data indicate that ACTIBIND should be tested for its potential as a new antiangiogenic modality for the treatment of melanoma.

Direct isolation of nucleic acids from the environment may be useful in several respects, including the estimation of total biomass, detection of specific organisms and genes, estimations of species diversity, and cloning applications. We have developed a method that facilitates the concentration of microorganisms from aquatic samples and the extraction of their nucleic acids. Natural water samples of 350 to greater than 1,000 ml are concentrated on a single cylindrical filter membrane (type SVGS01015; Millipore Corp., Bedford, Mass.), and cell lysis and proteolysis are carried out within the filter housing. Crude, high-molecular-weight nucleic acid solutions are then drawn off the filter. These solutions can be immediately analyzed, concentrated, or purified, depending on the intended application. The method is simple, rapid, and economical and provides high-molecular-weight chromosomal DNA, plasmid DNA, and speciated RNAs which comigrate with 5S, 16S, and 23S rRNAs. The methods presented here should prove useful in studying both the ecology and the phylogeny of microbes that resist classical culture methods.

Abstract Thirty years ago, 8 countries of the Hindu Kush–Himalayan region (Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, and Pakistan) realized the importance of mountains and established the International Centre for Integrated Mountain Development (ICIMOD). With an 8-country charter, ICIMOD serves as a regional intergovernmental center for cooperation on the sustainable development of the Hindu Kush–Himalayan region. ICIMOD believes in a future in which the region's mountain people can experience enhanced livelihoods, equity, and social and environmental security; in which they can adapt to environmental, socioeconomic, and climate change; and in which generations of mountain and downstream populations can enjoy the benefits and opportunities afforded by the region's natural endowment. ICIMOD foresees a future in which the role of the region, as the water tower for more than a billion people, a cultural and spiritual hub, the home of global biodiversity hotspots, a significant ecological buffer zone, and a source of resources and services for mountain and lowland people, is upheld, valued, and recognized globally and regionally.

Graph Neural Networks (GNNs) are a popular approach for predicting graph structured data. As GNNs tightly entangle the input graph into the neural network structure, common explainable AI approaches are not applicable. To a large extent, GNNs have remained black-boxes for the user so far. In this paper, we show that GNNs can in fact be naturally explained using higher-order expansions, i.e., by identifying groups of edges that jointly contribute to the prediction. Practically, we find that such explanations can be extracted using a nested attribution scheme, where existing techniques such as layer-wise relevance propagation (LRP) can be applied at each step. The output is a collection of walks into the input graph that are relevant for the prediction. Our novel explanation method, which we denote by GNN-LRP, is applicable to a broad range of graph neural networks and lets us extract practically relevant insights on sentiment analysis of text data, structure-property relationships in quantum chemistry, and image classification.

Objective Studies on the association between clinical vertebral fractures (CVFs) and the subsequent risk of cardiopulmonary diseases, including aortic dissection (AD), congestive heart failure (CHF), pneumonia and acute respiratory distress syndrome (ARDS) are scarce. Therefore, we used the National Health Insurance Research Database to investigate whether patients with CVF have a heightened risk of subsequent AD, CHF, pneumonia and ARDS. Design The National Health Insurance Research Database was used to investigate whether patients with CVFs have an increased risk of subsequent AD, CHF, pneumonia and ARDS. Participants This cohort study comprised patients aged ≥18 years with a diagnosis of CVF and were hospitalised at any point during 2000–2010 (n=1 08 935). Each CVF patient was frequency-matched to a no-CVF hospitalised patients based on age, sex, index year and comorbidities (n=1 08 935). The Cox proportional hazard regressions model was used to estimate the adjusted effect of CVF on AD, CHF, pneumonia and ARDS risk. Results The overall incidence of AD, CHF, pneumonia and ARDS was higher in the CVF group than in the no-CVF group (4.85 vs 3.99, 119.1 vs 89.6, 283.3 vs 183.5 and 9.18 vs 4.18/10 000 person-years, respectively). After adjustment for age, sex, comorbidities and Charlson comorbidity index score, patients with CVF had a 1.23-fold higher risk of AD (95% CI=1.03–1.45), 1.35-fold higher risk of CHF (95% CI=1.30–1.40), 1.57-fold higher risk of pneumonia (95% CI=1.54–1.61) and 2.21-fold higher risk of ARDS (95% CI=1.91–2.57) than did those without CVF. Patients with cervical CVF and SCI were more likely to develop pneumonia and ARDS. Conclusions Our study demonstrates that CVFs are associated with an increased risk of subsequent cardiopulmonary diseases. Future investigations are encouraged to delineate the mechanisms underlying this association.

ABSTRACT A 34-year-old woman with hypertension and hypokalemia was found to have a carcinoma of the adrenal cortex. Excretion of urinary corticoids and 17-ketosteroids was normal. Urinary aldosterone excretion was high and was unchanged by sodium loading and plasma renin concentration was low. She has remained well for 6 months following surgery with return of blood pressure and serum potassium to normal.

ABSTRACT In football, unpredictable events (e.g. unexpected landings) seem to play a crucial role in the mechanism of non-contact knee injuries. This study investigated the effects of a single bout of an injury preventive warmup protocol on biomechanical landing stability and decision-making quality during preplanned and unanticipated jump-landings. A crossover study on 18 male amateur football players was performed. The participants completed a standard (ergometer) and an injury-preventive warmup protocol (Prevent injury and Enhance Performance (PEP)) on two different test days. After each protocol, participants performed countermovement jumps with preplanned (landing side displayed before takeoff) and unanticipated (landing side shown after takeoff) single-leg landings on a force plate. Outcomes were landing stability (height and time of the maximum vertical ground reaction force (pGRF), centre of pressure (CoP), the number of standing errors (ground contact with free leg)) and decision-making quality (landing error (wrong foot) count). Carry-over and crossover-tests were performed to find potential between-condition-differences. No carry-over effects occurred (p > .05). The PEP led to a reduced CoP trace length (−18.4 ± 32.2%, p = .021) and earlier occurrence of pGRF (−4.72 ± 6.78%, p = .017) in the preplanned condition. No significant between-treatment-differences occurred within the unanticipated landings and decision-making quality (p > .05). The primarily neuromuscular warmup protocol affects landing stability in the preplanned condition. However, it does not seem to better prepare football players for unpredictable events than a standard warmup. Trial registration: German Clinical Trials Register identifier: DRKS00016942. Highlights Adapting movements rapidly to unanticipated external stimuli (e.g. unexpected landings) is crutial to prevent injuries in football It is unclear wether popular neuromuscular injury preventive warmup programmes (e.g. Prevent injury and Enhance Performance (PEP)) adaquatly prepare athletes for these situations Our study shows that the PEP warm up programme has acute effects on anticipated landing stability, but no influence on unanticipated landings or decision making quality Classic neuromuscular warm up programmes may not be the optimal choice to prepare athletes properly for the upcoming motor-cognitive demands in a football match

The purpose of this pilot study was to compare the reliability of three collection methods (draining, chewing of gum base, and the Saxon test) for whole saliva using a sample of middle-aged and older ambulatory adults (n = 18) with proven salivary gland hypofunction. The results demonstrated high reliability (r values ranging from 0.91 to 0.80, p < 0.001) for all three methods. MANOVA analysis revealed significant (p < 0.001) differences in flow rates among the draining, chewing-stimulated, and Saxon methods.

Damage of large arteries is a major contributory factor to the high pulse pressure observed in patients with end-stage renal disease. Whether incremental modulus of elasticity (Einc), a classic marker of arterial stiffness, can predict cardiovascular mortality has never been investigated. A cohort of 79 patients with end-stage renal disease undergoing hemodialysis was studied between September 1995 and January 1998. Mean age at entry was 58+/-15 years. The duration of follow-up was 25+/-7 months, during which 10 cardiovascular and 8 noncardiovascular fatal events occurred. At entry, carotid Einc was calculated from measurements of diameter, thickness (echo-tracking technique), and pulse pressure (tonometry). Based on Cox analyses, 2 dominant factors emerged as predictors of all-cause and cardiovascular mortality: increased Einc and decreased diastolic blood pressure. Lipid abnormalities and the presence of previous cardiovascular events interfered to a smaller extent. After adjustment for confounding variables, the odds ratio for Einc >/=1 kPa-3 was 9.2 (95% confidence interval, 2.4 to 35.0) for all-cause mortality. These results provide the first direct evidence that in patients with end-stage renal disease undergoing hemodialysis, arterial alterations, as determined from carotid Einc, are strong independent predictors of all-cause and cardiovascular mortality.

A supercritical carbon dioxide (S-CO2 ) gas turbine can generate power at a high cycle thermal efficiency, even at a modest temperature level of 500–550°C. Its high thermal efficiency is attributed to markedly reduced compressor work at the vicinity of the critical point. Furthermore, the reaction between Na and CO2 is milder than that between H2 O and Na. Consequently, a more reliable and economically advantageous power generation system is achieved by coupling with a Na cooled fast reactor. In a typical design, the reactor thermal power, a turbine inlet pressure and an inlet temperature are, respectively, 600 MW, 20 MPa and 527°C. In the S-CO2 gas turbine system, a partial cooling cycle is used to compensate a difference in heat capacity for the high-temperature – low-pressure side and the low-temperature – high-pressure side of the recuperators to achieve high cycle thermal efficiency. The flow is divided into two streams before the precooler. One stream goes to recuperator 2 via a main compressor (MC); the other goes to recuperator 1 via a bypass compressor (BC). The performance and integrity of these two compressors are crucial. As described herein, an aerodynamic design of BC is given. The inlet temperature, inlet pressure, exit pressure and mass flow rate are, respectively, 77°C, 8 MPa, 20 MPa and 1392 kg/s. The salient features of this compressor are its compact size and a large bending stress caused by the large mass flow rate. The number of stages is numerous associated with the large enthalpy rise compared with MC. To achieve as high efficiency as possible, not a centrifugal type but an axial type is examined first. The aerodynamic design was conducted using one-dimensional design method, where the loss model of Cohen et al. is used. Its aerodynamic design enables the use of several stages and provides total adiabatic efficiency of 21 and 87%, respectively. Then, CFD analysis was conducted using “FLUENT”. Blade shapes were prepared based on flow angles and chord length obtained in the aerodynamic design. The CO2 properties in a fluid computer dataset “PROPATH” were used. The features of gas velocity distribution and pressure distribution were confirmed to the fundamental knowledge. The value of the calculated flow rate coincided very well with that of the design.Copyright © 2009 by ASME

One of the most important developmental tasks in adolescence is the acquirement of autonomy and independence. A sample of 1240 adolescents has been assessed with Personal Autonomy Questionnaire from Cognitrom Assessment System), regarding 4 dimensions of autonomy: value, behavioural, cognitive and emotional autonomy. The results show that late adolescents have a more developed value, behavioural and cognitive autonomy than middle adolescents, and the urban area residents have a better developed autonomy in all its dimensions than rural area residents. No significant differences between male and female were found. Theoretical and practical implications of the study are discussed.

The effects of shaping time, energy level, and input count rate upon energy resolution, peak shift, and unpiledup output rate are presented for a representative set of germanium (Ge) spectrometer systems. The shaping amplifiers for each spectrometer incorporated semi-Gaussian time-invariant filters. Resoltion data for input count rates from 103 counts per second to greater than the maximum unpiled-up output rate are presented for each spectrometer. The resolution data presented for low energies (6keV), and medium and high energies (> 1MeV) should allow an experi-. menter to estimate the trade-offs between the conflicting requirements for resolution and output count rate for different types of Ge spectrometers.

Vitamin D has recently attracted a considerable amount of media attention. This article investigates whether the notion of a widespread vitamin D deficiency is justified in the UK, and what effect it might have on the general populace. Also considered are which physiological systems vitamin D affects in addition to bone remodelling, as well as the latest findings as to how this vitamin can benefit the body. Reasers are also given information as to which medications might adversely affect vitamin absorption, which patient groups are most at risk of deficiency, and the most practical and cost-effective means to treat patients suffering from a lack of vitamin D.

A general theorem is proved on the density matrix of quantum statistics. Let the density matrix be ρ{M}=exp[−β ∑ l=1MHl], where the operators Hl's are not always commutable. ρ{M} can be expanded in series of the form ρ{M}=(ΣM≧ ∑ i=1nmi, n≧0Σ{m1}M···{mn}M)ρ*{m1}···ρ*{mn}ρ{M−m1−···−mn}, where {m1}M, ··· {mn}M are subsets of operators chosen from the set {M} and operators belonging to different subsets are commutable. The summation is over all the possible choices of the sets {m1}, ··· {mn}. ρ{k} is defined by ρ{k}=[Π{k}exp(−βHi)]s, where suffix s means the symmetrization by changing the order of the products. And ρ*{m} is defined by ρ*{m}=(Σ{k}m)(−)m−kρ{k}ρ{m−k}, which is proved to be O(βm+1). Some possible applications are briefly discussed.

The aims of this study were to identify which factors may lead to crisis for people with dementia and their carers and identify interventions these individuals believe could help in crisis. Qualitative study using focus groups to compare the perspectives of people with dementia, family carers and healthcare professionals on causes of crises and crisis interventions. To help in a crisis, people with dementia were favourable towards support from family and friends, access to mobile phones and home adaptations to reduce risks. Carers were keen on assistive technology and home adaptation. Both carers and staff valued carer training and education, care plans and well-coordinated care. Staff were the only group emphasizing more intensive interventions such as emergency home respite and extended hours services. In terms of causes of crises, people with dementia focused on risks and hazards in their home, whereas family carers emphasized carer stress and their own mental health problems. Staff, in contrast were concerned about problems with service organization and coordination leading to crises. Physical problems were less commonly identified as causes of crises but when they did occur they had a major impact. Practical interventions such as home adaptations, assistive technology, education and training for family carers, and flexible home care services were highly valued by service users and their families during times of crisis and may help prevent hospital admissions. Specialist home care was highly valued by all groups.

The reefing line control design of parachute is very important to the safety of decelerator. In this paper, a Fluid structure interaction method is proposed to analyse the very flexible parachute reefing force. With the proposed method, the parachute opening shock can be assessed with a given reefing line length and cutting line time. In addition, through this method the cutting line time can be studied without high cost experiment.

We demonstrate a high-speed spectral domain optical coherence tomography (SD-OCT) system capable of acquiring individual axial scans in 24.4 micros at a rate of 19,000 axial scans per second, using an InGaAs line scan camera and broadband light source centered at 1.31microm. Sensitivity of >105 dB over a 2-mm depth range was obtained with a free-space axial resolution of 12-14 microm, in agreement with our signal-to-noise ratio predictions. Images of human tissue obtained in vivo with SD-OCT show similar penetration depths to those obtained with state-of-the-art time domain OCT despite the ten-fold higher image acquisition speed. These results demonstrate the potential of 1.3 microm SD-OCT for high-speed and high-sensitivity imaging in patients.

Purpose The purpose of this paper has been to identify and describe the demographic, social and clinical characteristics of persons admitted to an Irish district lunatic asylum in the late 19th century as exemplified by the records of the Sligo District Lunatic Asylum. Some 21st century comparisons and epidemiological considerations from the same catchment area have been attempted. Method The register entries and case books of a series of consecutive admissions to Sligo District Asylum during the decade 1892–1901 were surveyed in the Irish National Archive. Conclusions Most admitted patients were of lower socio-economic status, the majority male, poorly literate, unmarried and described as suffering from mania or melancholia. Most were first admissions. The predominant (62.5%) reason given for admission was for assault or threat of assault. These admissions were by order of the Lord Lieutenant as ‘dangerous lunatics’. Although it may be maintained that this admission process was a device of social convenience to maintain the peace and integrity of local communities and the convenience of families, clinical information indicates that the majority of admissions had symptoms of mental disorder recognisable in terms of 21st century psychiatric diagnostics.

In an integrated, dynamic and ever changing world, it is imperative that students are able to transition between jobs irrespective of qualifications. Studies show that graduates are inadequately prepared for the working world. In an attempt to address this need a postgraduate certificate course was redesigned to follow a constructionist approach integrated with mobile technology. Data was collected from 2 learning designers and 29 students, forming a qualitative study. An evaluation of the activities and learning survival skills in the course was done using the Technology Integration Matrix (TIM). The results indicated that technology was integrated on various levels and students achieved a multitude of skills, making them more confident in their use of technology. Feelings of anxiety, incompetence and resistance were transformed to resilience, motivation and comfort. The art to address graduate preparedness for work lies in effective course design and a constructionist forward thinking approach to learning.

This paper challenges the idea that emissions of greenhouse gases simply increase over time with income. It adopts a 200-year perspective and includes the important flows of greenhouse gases related to agriculture, not just the CO2 from fossil fuels. The result is that the pattern of Swedish total greenhouse gas emissions over time resembles an N. In contrast, when only emissions from fossil fuels are counted, the pattern over time resembles an inverted U. Among the most important factors generating emissions in agriculture, forest management was especially important, but in addition, draining of wetlands for agriculture played a substantial role. I I t is useful to know the historical development of pollution in order to understand its current and future development. It is important to adopt a sufficiently long-term perspective, one century into the future and two centuries into the past, to understand the interplay between developmental and environmental processes, especially for pollutants like greenhouse gases that have a long lifespan in the atmosphere. 2 Historical emissions of greenhouse gases are also of interest when it comes to the responsibility of individual countries in reducing emissions. 3 If countries’ responsibilities for past global warming were to be taken into account in present climate-change negotiations, historical emissions would have political implications. Sources that were more influential in the past may not be so influential today, and vice versa. In addition, it may be the case that we get a biased picture of the historical development if we base our understanding simply on the development of carbon dioxide (CO2) emissions from fossil fuels. It is widely believed that emissions of CO2 from fossil fuels always increase with increasing income, although emissions have fallen in Sweden and a few other European countries in the last few decades.This paper shows that, in fact, taking account of the historical development of all relevant greenhouse gases changes this picture profoundly. Agriculture, including forestry, has gone through substantial changes over the last 200 years, and has played an important role in greenhouse gas emissions. These changes are depicted and their effects estimated in this paper. The pattern that emerges is not a simple increase of greenhouse gas emissions over time, but one revealing that emissions have increased in some periods and decreased in others. Maximal emissions occurred not in the twentieth century, but

The mechanism of DNA adduct formation by acroleins substituted with good leaving groups in the beta-position was investigated using [3-2H]-3-(p-nitrophenoxy)acrolein (1). Reaction of 1 with guanosine at acidic pH produced 9-beta-D-ribofuranosylpyrimido[1,2-alpha]purin-10(3H)-one containing equal amounts of deuterium at both carbons 6 and 8, indicating that hydrolysis of 1 to beta-hydroxyacrolein (malondialdehyde) occurred prior to reaction with guanosine. In contrast, reaction of 1 with deoxyguanosine at neutral pH produced 9-(beta-D-2'-deoxyribofuranosyl)pyrimido[1,2-alpha]purin-10(3H)-one with deuterium selectively incorporated at position 8. This indicates that the pyrimido[1,2-alpha]purin-10(3H)-one adduct forms by 1,2-addition of the exocyclic amino group of deoxyguanosine to the aldehyde carbon of 1 followed by cyclization with the ring nitrogen. In concert with these observations, reaction of 1 with p-nitroaniline produced 3-[(p-nitrophenyl)amino]acrolein with deuterium exclusively in the aldehyde carbon. These observations define the chemical steps in DNA adduct formation by acroleins substituted at the beta-position with good leaving groups. In addition, they explain the relatively modest dependence of mutagenicity on leaving group ability in this series of compounds.

The toxicity of DL-methionine and methionine hydroxy analog infused into the rumen or abomasum was gauged by relative feed consumption. A continuous intraruminal infustion of at least 3 days' duration of DL-methionine equalent to about 2.5% or more of dietary dry matter intake was required to reach a toxic amount. This was approximately four times the amount necessary when it was infused into the abomasum. Methionine hydroxy analog equalent to about 1% or more of dietary dry matter intake was toxic when infused into either rumen or abomasum. This is in large excess of suggested amounts of analog supplementation. Reduced palatability is likely to occur in advance of reduced intake due to toxicity.

People’s sentiments are known to have a large impact on changes in stock prices, products sales, and trends. Since web users generally state their opinion in various languages, it is important to develop a method of multilingual sentiment analysis for web texts. In this research, we design a multilingual sentiment analysis method based on word to word translation using a sentiment dictionary in arbitrary native language. This method consists of three phases: morphological analysis of text, a sentiment extraction of each word with sentiment dictionary, and a sentiment extraction of text based on words sentiments. We conduct a sentiment classification experiment for tweets in English, German, French, and Spanish. In the experiment, we evaluate our classifier’s performance by comparing the classifier with the other previous classifiers based on the evaluation standards "Accuracy", "Precision", "Recall", and "F1 score". The experimental results show that our classifier has an applicability to sentiment analysis for multilingual, because our classifier’s performance is independent of the differences languages.

The magnetic properties of the lanthanide chalcogenides are much less explored than the monopnictides. The main reasons are probably difficulties in syntheses and the crystals growth. In particular, the properties of monotellurides are almost completely unknown. The dysprosium tellurides: DyTe and Dy2Τe3, crystallize in the structures related to the rock salt type. The first compound is metallic, while the second — semiconducting. Dysprosium sesquitelluride behaves like a simple antiferromagnet with the Neel temperature equal to 4.1 K [1]. We synthesized and investigated the dysprosium monnotelluride in order to examine a change of exchange interactions after transition to the metallic state.

Mailing address: Gregorina Silva Ribeiro Rocha Instituto de Pesquisa e Tecnologia ITP Avenida Murilo Dantas, 300 Farolândia CEP: 49032-490 Aracaju, Sergie, Brasil E-mail: gregorinarocha@gmail.com ABSTRACT Purpose: to evaluate the perception of the level of quality of life in subjects with tinnitus, with and without hearing loss. Methods: a cross-sectional quantitative study. A total of 189 subjects (mean age 53.06 years) divided into four groups. Group 1: subjects with normal auditory thresholds without tinnitus complaint; Group 2: subjects with normal auditory thresholds and tinnitus complaint; Group 3: subjects with sensorineural hearing loss without tinnitus complaint; Group 4: subjects with sensorineural hearing loss and with tinnitus complaint. Levels of quality of life were investigated through the World Health Organization Quality Of Life (WHOQOL) website brief and psycho-emotional and functional aspects of patients with tinnitus through the Tinnitus Handicap Inventory (THI). Statistical analyzes, comparisons among groups and descriptive analysis were performed, considering a significance level of 5%. Results: the overall mean scores of quality of life in group 4 (56.07) were smaller than those of group 1 (64.67) (p<0.05). The subjects with tinnitus complaint presented a moderate level of disturbance of the symptom. Conclusion: tinnitus interferes in the quality of life of individuals who had preserved or altered auditory thresholds. Therefore, means to reduce the discomfort caused by tinnitus symptom should be developed, in order to improve patients’ quality of life.

SIMIlar to dISNEylaNd or the tourist attractions in Las Vegas, parts of contemporary China resemble a theme park, as copycat architecture and towns can be found throughout the country. From the “Sphinx” on the outskirts of Shijiazhuang in Hebei Province to the French aristocratic Chateau Laffitte Hotel (a reproduction of the seventeenth-century baroque Château de Maisons-Laffitte) in Beijing’s suburbs, from the “Eiffel Tower” in the Paris-styled town of Tianducheng in Hangzhou’s suburbs in Zhejiang Province to the “London Bridge” in Suzhou in Jiangsu Province, Chinese tourists can travel around the world without leaving their own country. The list can extend to replicas of European towns such as Hallstatt (an imitation of the Austrian village Hallstatt near the Alps) in Huizhou in Guangdong Province, Florence town in Tianjin, and Venice town in Dalian, among others. We can also discover several knock-off “White Houses” and “Capitol Hills” built by Chinese governmental officials and businessmen. Furthermore, it is said that a copycat version of Manhattan will be completed in Tianjin in 2019. It appears that China is coming to resemble a film set! In this essay, I introduce Thames Town, an English-themed town in the suburbs of Shanghai, and present how it has been received by English journalists, Chinese residents and tourists, and Chinese nationalists and their interlocutors. I also comment on their receptions. One of the most famous copycat towns in China is Thames Town, an English-styled town located in Songjiang, in the southwest of Shanghai’s suburbs.1 Alongside the German town (Anting), the Scandinavian town (Luodian), the Italian town (Pujiang), the Spanish town (Fengcheng), the Canadian town (Fengjing), and others, Thames Town is part of the “One City, Nine Towns” project that the Shanghai government initiated to

A community-based survey was conducted to assess the prevalence of G6PD deficiency and malaria in two villages (St. Martins, Dagua) of Wewak district, East Sepik Province, Papua New Guinea. A total of 551 individuals were recruited for the study. Malaria was diagnosed in 96 cases (17.4%), and 28 subjects with G6PD deficiency (5.1%) were identified by the WST-8⁄1-methoxy PMS method. The sequence of the entire G6PD gene was determined in 19 of the 28 G6PD-deficient cases. We found ten cases with the G6PD Jammu variant (871 G>A, 1311 C) and eight cases with the G6PD Vanua Lava variant (383 T>C). A novel mutation (595 A>G) predicting an amino acid change from isoleucine to valine was identified. This mutation has not been reported to date and was named G6PD Dagua. The detection of three G6PD variants indicates the heterogeneity of the studied population, and these variants could be important genetic markers for clarifying the gene flow among the population of Southeast Asian and Pacific Island countries.

Previous studies suggest that the solubility of Al in acid forest soils may be expressed as the log Al 3+ activity = -n pH + log K H-Al + log Al P /C P concentration ratio, with Al and C P representing pyrophosphate-extractable Al and C, respectively, and K H-Al is is the binding constant of Al to protonated complexation sites on soil organic matter (SOM). We show that a slightly modified model, in which Al is replaced by Al org (= Al P - KCl-extractable Al), successfully describes the concentration ofAl in A and B horizons of a wide range of acid forest soils (Typic Dystochrepts) developed in different parent materials from a large number of spruce [Picea abies (L.) Karst.] and mixed forest stands in southern Poland. Analysis of the data suggests a reaction stoichiometry of n = 1.27 and log K H-Al = 1.98 with R 2 = 0.76. Furthermore, statistical analysis of a large set of published data, in addition to our own data from the Polish soils, indicates that log[Al org /C P ] is significantly correlated with soil pH measured in 1 mol L -1 KCl (pH KCl ), suggesting that the Al binding to SOM is less at small pH KCl due to increased competition with H + : log[Al org /C P ] = 0.82 pH KCl - 4.16 (R 2 = 0.77, n = 276). Combining the two equations gives a simple Al solubility model for mineral horizons in acid forest soils: log Al = -1.27pH + 0.82pH KCl - 2.18 (R 2 = 0.82, n = 127). In this equation, pH KCl relates to chemical soil properties, whereas the pH of soil water also depends on solution characteristics like ionic strength. The equation may be applied to acid forest soils having a soil solution pH in the range of 3.0 to 4.2. Such conditions are rather common in surface horizons (A, E, and upper B) of acid forest soils of the temperate and boreal zones.

Objective: To analyze the associations between marine n-3 polyunsaturated fatty acids (PUFAs) and blood pressure (BP), resting heart rate (HR), and heart rate variability (HRV) in a population highly exposed to methylmercury through the diet. Methods: Concentrations of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in erythrocytes membranes were measured in 180 French Polynesian adults (≥18 years) residing in Tubuai, which is a community with a traditional lifestyle, or Papeete, which has a modern lifestyle. HRV was measured using a 2-hour ambulatory electrocardiogram (Holter). Resting HR and BP were measured using standardized protocols and pulse pressure (PP) was calculated as systolic BP − diastolic BP. The associations between n-3 PUFAs and the dependent variables were studied using simple and multiple linear regressions. Results: Increasing DHA concentration was associated with lower resting HR (β = −2.57, p = 0.005) and diastolic BP (β = −1.96, p = 0.05) and higher HRV in multivariable models. Specifically, DHA was associated with high frequency (HF; β = 0.19, p = 0.02) and the square root of the mean squared differences of successive R-R intervals (difference between two consecutive R waves; rMSSD; β = 0.08, p = 0.03), which are specific indices of the parasympathetic activity of the autonomic nervous system. Conclusion: DHA was associated with lower BP and resting HR and higher HRV among French Polynesians who are also exposed to high methylmercury levels.

Patients requiring urgent cardiac surgery are usually already taking antiplatelet drugs including aspirin and a P2Y12 ADP receptor antagonist (e.g., clopidogrel, prasugrel or ticagrelor). This presents clinicians with the challenge of balancing the risk of thrombotic complications, if antiplatelet drugs are stopped before surgery, with the problems of excessive bleeding when surgery is performed in the absence of adequate platelet function. Preoperative platelet function monitoring is able to identify when patients have recovered platelet function. The Multiplate® (multiple electrode impedance platelet aggregometer) is a point of care device that enables monitoring of platelet function. The authors offer recommendations based on real‐world, collective experience in the use of platelet function monitoring. These cover the use of the Multiplate® analyser to predict the need for platelet transfusion in the perioperative period and the individualized waiting period after cessation of P2Y12 ADP receptor antagonists before cardiac surgery.

The Lower Jurassic Toarcian Stage (c. 183–174 Ma) is marked by one of the largest global exogenic carbon-cycle perturbations of the Phanerozoic, which is associated with the early Toarcian Oceanic Anoxic Event (T-OAE; c. 183 Ma). Climatic and environmental change at the T-OAE is reasonably well constrained in the marine realm, with marine anoxic or euxinic conditions developing locally across both hemispheres, at the same time as the T-OAE negative carbon-isotope excursion. However, high-resolution stratigraphic comparison between different palaeo-ocean basins and with the continental realm can be complicated. Palaeomagnetic reversals can provide a precise and accurate stratigraphic correlation tool between marine and continental sedimentary archives, and even between sedimentary and igneous successions. Here, we present a high-resolution magnetostratigraphic record for the Toarcian Stage in the biostratigraphically complete and expanded Llanbedr (Mochras Farm) Borehole, Cardigan Bay Basin, Wales. This study provides the first geomagnetic polarity reversal scale that is integrated with high-resolution biostratigraphy and carbon-isotope stratigraphy for the entire Toarcian Stage. This stratigraphic framework also provides a new, precise correlation with the basalt lava sequence of the Karoo–Ferrar Large Igneous Province, linking the Pliensbachian–Toarcian boundary and T-OAE climatic and environmental perturbations directly to this episode of major volcanic activity. Supplementary material: Details of the palaeomagnetic data and dip direction are available at https://doi.org/10.6084/m9.figshare.c.4052720

We report on the development of an on-line learning algorithm for ANCFIS, a neuro-fuzzy architecture employing complex fuzzy sets. ANCFIS uses a hybrid learning rule, with rule consequent parameters determined by least-squares estimation in the forward pass, and premise parameters determined by a combination of gradient descent and chaotic simulated annealing in the backward pass. Our online learning algorithm replaces these with recursive least-squares in the forward pass, and the downhill-simplex algorithm in the backward pass. Experimental results on two time-series datasets show that this technique is comparable to existing results, although slightly inferior to the off-line ANCFIS results.

Buckling and postbuckling behavior of thin composite cylindrical shells reinforced by carbon nanotubes (CNTs), surrounded by elastic media and exposed to uniform temperature rise, are investigated in this article. CNTs are reinforced into isotropic matrix phase through uniform distribution or functionally graded distributions across the thickness direction. Material properties are assumed to be temperature dependent, and effective elastic moduli of CNT-reinforced composite are determined according to extended rule of mixture. Formulations are based on the classical thin shell theory taking Von Karman–Donnell nonlinearity, surrounding elastic media and elastic constraints of boundary edges into consideration. Multi-term solutions of deflection and stress function are assumed to satisfy simply supported boundary condition, and Galerkin method is applied to obtain nonlinear relation of thermal load and deflection. An iteration algorithm is used to determine buckling temperatures and postbuckling paths. Numerical examples are given to analyze the effects of volume fraction and distribution type of CNTs, geometrical parameters, degree of tangential edge constraint, buckling mode, and surrounding elastic media on the buckling temperatures and postbuckling strength of thermally loaded nanocomposite cylindrical shells.

Background : The aim of this study is to compare intraoperative infiltration of periarticular soft tissues versus the use of peripheral nerve blocks (sciatic and femoral) for postoperative pain management in total knee arthroplasty. Methods : We prospectively evaluated 60 patients who were divided into two equal groups: group A, with intraoperative infiltration and group B, with femoral and sciatic nerve block before surgery. Results : Pain was significantly lower in group B (block) than in the control group A (infiltration) at 4 and 8 hours after surgery (p = 0.008). Two and three days after surgery, pain curve was inverted and it was statistically lower in group A (p = 0.009 and p = 0.023, respectively). Conclusions : Results showed that both methods were effective in the treatment of pain after surgery and even to reduce opiate use. Low levels of pain and less use of opioids in the immediate postoperative period led to a better rehabilitation and comfort of the patient

Mesoscale eddies occurring in the world’s oceans typically exist in pairs known as mesoscale dipole eddies or simply dipole eddies. Tropical cyclones (hereafter TCs) that move over the world’s oceans often encounter and interact with these dipole eddies. Through this interaction, TCs induce significant perturbations in the mesoscale eddies. However, the specific influences that the passage of a TC on a dipole eddy have not been addressed. In this paper, a case study of the dipole eddy’s response to the passage of a TC is conducted by using satellite observations and numerical simulation. The passage of a TC induces a long-duration response in the dipole eddy. First, the cyclonic ocean eddy component (COE) of the dipole is amplified, and the anticyclonic ocean eddy component (AOE) is weakened or even destroyed during the interaction. The amplification of the COE and weakening of the AOE primarily manifests as a change in their amplitudes and radii and as the adjustment of their vertical structure. The dipole eddy’s response to the interaction with a TC manifests as an upwelling anomaly and the injection of positive relative vorticity. Following the passage of the TC, the COE gradually stabilizes, and AOE slowly recovers after the disturbance energy from the interaction dissipates, which facilitates the reestablishment of the dipole eddy. The dipole reaches an equilibrium state through a quasi-geostrophic adjustment process. As a consequence, the overall effect of the interaction of the dipole with the TC leads to an asymmetric signature on the dipole eddy. The eddy–eddy interaction in a dipole may allow it to stabilize in a shorter time relative to that of a solitary eddy.

A male child discovered to have cystinosis and Fanconi syndrome at the age of 2 years 8 months was hospitalized repeatedly for episodes of hyponatremic, hypokalemic dehydration and acidosis. Attempts to correct the fluid and electrolyte abnormalities by increasing progressively the supplements of sodium chloride, sodium bicarbonate, and potassium chloride resulted only in an exacerbation of the symptoms. Tests of discrete renal functions and metabolic balance studies disclosed that, although all disturbances were expressions of the primary disease, their severity was enhanced considerably by the extracellular volume expansion induced by the vigorous therapy. Restriction in water intake resulted in an improvement in the renal performance and in the clinical condition.

This paper presents a novel algorithm for autonomous guidance of spacecraft to approach and fly around a target satellite. Two primary constraints of the spacecraft thrusters are taken into account. Firstly, to solve the under-actuated control problem caused by the limitation of the thrusters installation, we present a phase-plane trajectory method which enables the spacecraft to enter the desired fly-around orbit without the input along LOS direction. Secondly, considering the on-off control problem caused by the thrusters providing constant force, a predictive control method is employed to guarantee the relative state can track the phase-plane trajectory precisely. Numerical simulations demonstrate the feasibility of the proposed algorithm.

BACKGROUND
To examine the relationship between personality type and physiological response to stress among juvenile delinquents.
METHODS
Delinquent males (N = 42, mean age 16.5, SD = 1) recruited from a convenience sample at local juvenile detention facility were compared to a male control sample from a local high school (N = 79; mean age 16.1, SD = 0.8). All participants completed the Weinberger Adjustment Inventory and a Stress-Inducing Speech Task during both of which heart rate was measured.
RESULTS
Compared to controls, delinquent youths showed significantly lower heart rates under both free association and stress conditions (p < 0.05) and a lower rate of increase during stressful stimuli (p < 0.05). Among delinquents, those with a non-reactive personality type appeared to show consistently lower levels of physiological arousal as measured by heart rate.
CONCLUSIONS
Delinquents consistently had lower overall levels of arousal as measured by heart rate. In delinquent boys, we also found a persistently low arousal group with a non-reactive psychological pattern. This combination may be a forerunner of future psychopathy or a product of the developmental trajectory that leads to and results from psychopathic behavior.

In this paper, we present a design method for a compact inverted Doherty power amplifier (IDPA), which has high-efficiency and high-power characteristics. An optimum load matching network and an additional offset line, after the matching network of the carrier amplifier, dynamically modulate the load impedance according to the input power drive, while the conventional Doherty power amplifier uses a quarter-wave line to do it. The operational principles and design guide are provided. For experimental verification, a 50-W Doherty amplifier was designed for the pi/4 differential quadrature phase-shift keying application at the 860-MHz band. The measured performance of the IDPA was compared with that of the balanced class-AB amplifier with the same output matching network. At an output power of 50 W, the IDPA performs with 3.16 dB better adjacent channel power ratio (-28 versus -24.84 dBc) and 6.15% higher power-added efficiency (59.02 versus 52.87%) than the class-AB amplifier does.

Doppler sonar observations from the Arctic Internal Waves Experiment and Arctic Leads Experiment in the Beaufort Sea are used to examine currents below the ice during spring conditions. Following two strong wind events, the dominant fine-scale current consists of both downward and upward propagating near-inertial internal waves. The downward propagating waves are most evident above 100 m depth, while the upward waves are most energetic below this depth. The appearance of these waves coincides in time and depth with a westward subinertial current following the winds with maximum speeds of 0.05 m s−1 at 100 m depth. Simple ray simulations show that the observed subinertial shear can significantly refract near-inertial waves with length scales similar to those observed. In particular, waves that propagate both in the direction of the current and toward the depth of maximum current are enhanced. These simulations suggest that the observed near-inertial wave enhancement is due, in part, to wave-shear effects rather than solely to surface forcing.

In the British Medical Joutrnal of December 4, 1937, Mr. R. Salisbury Woods described a case of union of the carpal scaphoid after six weeks' delay in treatment. The excellent result obtained in his case induced me to trace for review a patient treated in a similar conservative manner about a year previously. In this case the period between th_ accident and the institution of efficient treatment had been much longer-nearly three years-and the period of treatment had been correspondingly extended. The result, however, proved very satisfactory, and the publication of such a case may encourage others to consider conservative measures when treating this most troublesome injury.

Background: Children below five year constitute 14 % of total population in our country. They are vulnerable group deserving special health care. children are considered to be susceptible to host of disease and infection and the most important causes of under-five mortality are Acute Respiratory Infection (ARI), Preterm birth Complications, Diarrheal diseases, Intrapartum related complication, Malaria, Neonatal Sepsis, Meningitis and Tetanus. The objective of the present study was to study the health care seeking pattern of under five children in rural areas of Mandya District.Methods: A cross sectional study was conducted at Adichunchanagiri Institute of Medical Sciences, Bellur Cross from January 2017 to June 2017. All the children under the age of five years in the Rural Field Practise area of the AIMS, were included in the study.Results: Out of the 324 male children in present study only 90 (27.7%) of them had suffered from any kind of illness in the past three months of duration and 59 (29.4%) out of 201 Female children had fallen ill. Fever, Diarrhoea, Pnemonia were the most common illness seen among the children. The association between the gender and illness was found to be statistically not significant.Conclusions: Large number of parents availed government service due to fact that large number of families belonged to lower socioeconomic class. IEC activities should be enhanced so as to change the behavior of 100% mothers to seek the timely reference from a qualified Doctor for the illness and proper adherence to the treatment.

This essay explores the response to Andy Warhol's first exhibition at Galerie Sonnabend in Paris in the context of changes in advertising and the discourse of motorization in France.Comparing Warhol's "Death in America" paintings to Robert Delpire's pop advertisement for the Citroen DS uncovers the critical confusion and material stakes surrounding the convergence of art and advertising in the eaarly 1960s. The symbolic and material ubiquity that led Roland Barthes to describe the automobile as an "object-sign" set the stage for a conflict between art and advertising that resonated with debates surrounding pop art and an expanding consumer society in France.

The papers concerns the problem of the development and functioning of the alder ecosystem (Fraxino-Alnetum ) forming along the anthropogenic watercourse in the area of the city of Zabrze (Silesian Upland, southern Poland). The vegetation community develops on the habitat of highly contaminated with heavy metals. The investigated riparian alder is supplied by rainwater (urban rainfall/waste water), conducted in artificial riverbed in a tube and targeting the forest area. Despite the high content of some oxides (Fe 2O3, Al 2O3, P2O5) and heavy metals (Cd, Pb, Fe, Cu, Ni, Co) in soil and the existence of an artificial ditch the functioning of the examined ecological system is proper. This might be explained by the presence of silt, claim and loam fraction which deposited on the bottom of channel and in from the surrounding environment, which helps to increase the water capacity of the soil. These situations allow the proper functioning of the alder community. A community has got the proper structure similar to the system of natural character, manifested both in species composition, as well as the vertical structure of the vegetation. Soil cover the study area was completely destroyed and the soil has lost its natural horizons. As mentioned above the soil cover has a high content of heavy metals in excess of the permissible standards. For this reason these soils are classified as Anthrosols in accordance with WRB standards.

With the development of communication technology in recent years, many new industries such as big data and cloud computing have been born, and the scale of the Internet is constantly expanding. The original IPV4 address pool is on the verge of depletion, and a new IPV6 address pool has to be activated, which proves the huge amount of data flow. Multicast is a method that is ideally suited to the transmission of information on a large scale, but it has been unable to achieve the desired forwarding effect on the large-scale Internet due to a number of drawbacks, including difficulties in deployment. Previous researchers have proposed the SVRF series architecture of forwarding algorithms for routers/switches which have proven to be very efficient in carrier-grade networks, but they also suffer from excessive space consumption and long processing times. The architecture proposed in this paper is a front-end component capable of optimizing all SVRF series architectures. The framework operates several prime hash functions to generate an ordered set of prime key values as the key element to build the scalar pair of SVRF series algorithm, combining the distribution law of prime numbers, as well as re-hashing and other theoretical basis to improve the original SVRF architecture may bring hash collision and other problems. The proposed architecture enables less overall space resource consumption, faster operation of forwarding algorithms, and more efficient table lookup and forwarding of forwarding entries throughout the forwarding engine.

•" I "'HE number of legume bacteria (Rhizobium spp.) A in the soil obviously determines to a large extent the quantity of nitrogen fixed by plant-bacterial symbiosis. When farmers insure their soil supply of these organisms by inoculating and growing legumes in the rotation, the organisms added may influence the host plant in several ways, but the most obvious are in growth and nitrogen content. Previous to this, however, and with efficient strains of nodule bacteria, there is greater fixation of nitrogen, increased chlorophyll content, greater carbon dioxide assimilation, and increased rate of growth, all culminating in a greater amount of plant substance of higher nitrogen content than control plants. Some commercial cultures are advertised and sold for their content of superior strains of bacteria for crop production. The experiments here reported were carried out for the purpose of determining the value of some of these cultures, especially in regard to possible differences between humus and agar cultures. In addition, it was expected that the experiments would show whether any of the varieties of soybeans grown in the tests would prove superior in the production of dry matter and nitrogen.

We explore transport layer protocol design for an optical flow-switched (OFS) network. The design guarantees the reliable delivery of data files over an all-optical end-to-end flow-switched lightpath which is a burst-error channel due to gain transients in EDFAs. TCP performs poorly for OFS. TCP flow control and fair resource allocation with windowing are unnecessary in OFS networks since they are done via scheduling. In our protocol design, we optimize throughput efficiency and delay using file segmentation and reassembly, interleaving with forward error-correction and frame retransmission.

The objectives of this study were: a) to determine the prevalence of inadequate body fat determined based on body mass index (BMI), abdominal perimeter (AP) and relative body fat (%F), and biochemical indicators of cardiovascular risk, and b) to examine which body fat indicators better reflect the biochemical factors. BMI, %F, AP, glucose, triglycerides, total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured in 125 men. More than half the sample (56.8%) had low HDL and high BMI (58.4%) and %F (53.6%). There was a lower percentage of subjects with elevated LDL (40.8%), AP (38.4%), triglycerides (34.8%), glucose (27.2%), and total cholesterol (15.2%). AP was associated with four biochemical markers, whereas %F was associated with three and BMI with only two. The prevalence of risk factors was high. An AP >92 cm proved to be the best fat indicator, demons- trating that men are exposed to high levels of LDL, total cholesterol, triglycerides, and glucose.

The present study aimed at: (a) comparing/correlating indices of social skills repertoire and parents involvement in the upbringing of their children and (b) comparing fathers and mothers in the two set of indices. The sample was composed of 22 mothers and 13 fathers who had children in the 1 st grade at primary school. Both parents filled in the questionnaires Quality of Family Interaction from the Parents Perspective and the Social Skill Inventory (HIS- Del Prette). Data analysis showed no difference in involvement intensity of both parents with their children. Parents with better social skills repertoire were more involved in their children's upbringing. Such results suggest that the parents' social educative skills repertoire is very important in order to maximize the child development and also points to the need of wider programs in this area involving parents and aiming at improving the quality of the relationship with their children.

A woman in her 50s with morbid obesity and obstructive sleep apnea presented with 3 days of fever with a temperature up to 39 °C, anosmia, and shortness of breath. Physical examination findings were significant for oxygen saturation of 85% on room air and coarse rales at the lung bases bilaterally. Chest radiography was suggestive of bilateral multifocal pneumonia. Results of a nasopharyngeal swab for coronavirus disease 2019 (COVID-19) were positive by reverse transcriptase–polymerase chain reaction. She was admitted to the intensive care unit for management. Upon admission, the patient began hydroxychloroquine and azithromycin combination therapy. On hospitalization day 2, the patient developed acute respiratory distress syndrome (ARDS) requiring intubation and mechanical ventilation. Management strategies for refractory hypoxia were not successful until she was placed in a prone position. She was maintained in a prone position for 16 hours followed by supine positioning as tolerated for 4 hours a day. Given the treatment with hydroxychloroquine and azithromycin, serial electrocardiograms (ECGs) were performed to monitor QT interval during treatment. The ECG on hospitalization day 3 (Figure 1A) showed acute changes in comparison to her prior ECG (Figure 1B). Question: What is the cause of the Q waves and low amplitudes seen in the anterior precordial leads?
