Authors: Momoh James A. , Salkuti Surender Reddy 
Published: April 2016

Abstract
This paper proposes a stochastic optimization technique for solving the Voltage/VAr control problem including the load demand and Renewable Energy Resources (RERs) variation. The RERs often take along some inputs like stochastic behavior. One of the important challenges i. e., Voltage/VAr control is a prime source for handling power system complexity and reliability, hence it is the fundamental requirement for all the utility companies. There is a need for the robust and efficient Voltage/VAr optimization technique to meet the peak demand and reduction of system losses. The voltages beyond the limit may damage costly sub-station devices and equipments at consumer end as well. Especially, the RERs introduces more disturbances and some of the RERs are not even capable enough to meet the VAr demand. Therefore, there is a strong need for the Voltage/VAr control in RERs environment. This paper aims at the development of optimal scheme for Voltage/VAr control involving RERs. In this paper, Latin Hypercube Sampling (LHS) method is used to cover full range of variables by maximally satisfying the marginal distribution. Here, backward scenario reduction technique is used to reduce the number of scenarios effectively and maximally retain the fitting accuracy of samples. The developed optimization scheme is tested on IEEE 24 bus Reliability Test System (RTS) considering the load demand and RERs variation.

Abstract

Background: Traditional remedies employ herbal drugs for the treatment of liver ailments and hepatoprotection. Thus, the present study was designed to evaluate the hepatoprotective effect of “extract of Anacyclus pyrethrum Linn” (APE) against antitubercular drug-induced hepatotoxicity in rats.

Methods: Group I rats (normal control) received vehicle (1 % CMC), while group II rats (hepatotoxic control) isoniazid (INH) plus rifampicin (RIF) each 50 mg/kg/day po, for 28 days. Group III, IV and V rats were administered with APE 200, APE 400 and silymarin 100 mg/kg/day po, respectively, for 28 days. Concurrently, hepatotoxicity was tried to induce by coadministration of INH and RIF each 50 mg/kg/day po for 28 days in group III, IV and V rats. After 24 h of the last dosing, blood was obtained under light anesthesia and the rats were killed. Hepatoprotective effect was assessed by liver weight, relative liver weight and biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), serum bilirubin, cholesterol, total protein and albumin levels.

Results: Group IV rats showed significant (p<0.01) decrease in SGPT, SGOT, ALP, LDH, cholesterol, serum bilirubin, liver weight and relative liver weight Levels, while significant (p<0.01) increase in final body weight (b. wt.), total protein and albumin levels as compared to group II rats. Hepatoprotective effect of APE 400 mg/kg/day was comparable to that of silymarin 100 mg/kg/day and the hepatic marker levels were also restored. Hepatoprotective effect of APE was well supported by the histopathological results.

Conclusions: Hydroalcoholic APE root possesses hepatoprotective activity as it exhibited the protective effect against INH plus RIF-induced hepatotoxicity in rats.
Searching for the GOAT of tennis win prediction

Published: April 2016

AbstractSports forecasting models – beyond their interest to bettors – are important resources for sports analysts and coaches. Like the best athletes, the best forecasting models should be rigorously tested and judged by how well their performance holds up against top competitors. Although a number of models have been proposed for predicting match outcomes in professional tennis, their comparative performance is largely unknown. The present paper tests the predictive performance of 11 published forecasting models for predicting the outcomes of 2395 singles matches during the 2014 season of the Association of Tennis Professionals Tour. The evaluated models fall into three categories: regression-based, point-based, and paired comparison models. Bookmaker predictions were used as a performance benchmark. Using only 1 year of prior performance data, regression models based on player ranking and an Elo approach developed by FiveThirtyEight were the most accurate approaches. The FiveThirtyEight model predictions had an accuracy of 75% for matches of the most highly-ranked players, which was competitive with the bookmakers. The inclusion of career-to-date improved the FiveThirtyEight model predictions for lower-ranked players (from 59% to 64%) but did not change the performance for higher-ranked players. All models were 10–20 percentage points less accurate at predicting match outcomes among lower-ranked players than matches with the top players in the sport. The gap in performance according to player ranking and the simplicity of the information used in Elo ratings highlight directions for further model development that could improve the practical utility and generalizability of forecasting in tennis.
Phylogeny explains better than ecology or body size the variation of the first lower molar in didelphid marsupials

Published: April 2016

Abstract
Tribosphenic molars are considered great innovations in mammals and are related to several structures and variables that can explain adaptation. The aim of this study was to investigate the importance of body size and habitat relation, using a phylogenetic approach, in the first lower molar shape in didelphid marsupials. Geometric morphometric analyses of the lower molar’s shape were performed on 261 specimens, 130 females and 131 males, covering 14 genera and 37 species of the Didelphidae family. The molar conformation showed a larger talonid in relation to the trigonid in more arboreal genera, and narrower and longer molars in genera with a larger body size. Phylogeny was the variable with the highest explanation for both females and males (16.17% and 9.02%, respectively). The body size was significant in males, presenting an important influence on molar shape, while the body size in females was not significant when phylogenetic relationship was controlled for. In both sexes, habitat presents a strong effect of phylogeny, with no direct effect on molar shape. Didelphid molar shape is another result of its phylogenetic history and does not respond very much to environmental pressures. Male body size influences molar shape in didelphids, even in the presence of a strong phylogenetic signal.

Abstract
This paper used an equal volume impregnation method to produce egg yolk-egg white bimetallic-supported catalyst. Phase structure and crystal morphologies were characterized by X-ray diffraction, scanning electron microscopy, temperature programmed reduction (TPR), and inductive coupling plasma methods, and the paper discussed the effect of different metal loading, calcination temperature, and calcination time on the desulfurization activity. The experimental results showed that desulfurization performance increased first and then gradually decreased as metal loading, calcination temperature, and calcination time increased. The optimum preparation conditions of bimetallic catalyst were 8% NiO and 5% MnO2, the most suitable calcination temperature was 400°C, and the most suitable calcination time was 4 h. Finally, the eggshell, the egg white, and the egg yolk catalysts had its own different characteristics in the desulfurization processing: the eggshell catalyst showed a rapid reaction rate but lasted for a short time, the egg yolk catalyst showed a slow reaction rate but lasted for a long time, and the reaction rate and lasting time of the egg white were between the eggshell and the egg yolk.

Abstract
Andersen, V, Fimland, MS, Kolnes, MK, Jensen, S, Laume, M and Saeterbakken, AH. Electromyographic comparison of squats using constant or variable resistance. J Strength Cond Res 30(12): 3456–3463, 2016—The aim of the study was to compare the electromyographic (EMG) activity of vastus lateralis, vastus medialis, rectus femoris, and biceps femoris when performing the squat with constant resistance or variable resistance with 2 or 4 elastic bands, respectively, contributing with a mean of 39 and 73% of the total loads. Nineteen resistance-trained women performed 6 repetition maximum using 3 different experimental conditions: free weights (FW), free weights + 2 elastic bands (FW + 2EB), and free weights + 4 elastic bands (FW + 4EB). During analyses, each repetition was divided into 6 phases: upper (more extended knee), middle, and lower phase of the descending and ascending movements. Increased activation in the upper parts of the movement was observed for both variable resistance conditions compared with constant resistance (9–51%, p < 0.001–0.050). Further, a dose-response effect of variable resistance was observed in the upper ascending movement, with 4 elastic bands increasing muscle activation more than 2 elastic bands (7–28%, p = 0.003–0.007). For the whole movement, a 12% higher activation of the biceps femoris was observed for FW + 4EB compared with FW (p = 0.005). There were no differences between the other conditions in any of the muscles (p = 0.077–1.000). In conclusion, performing the squat using free weights in combination with elastic bands seems to be preferable compared with free weights alone and more so with a high contribution from variable resistance to the total load.

Abstract
Ferreira, DV, Ferreira-Júnior, JB, Soares, SRS, Cadore, EL, Izquierdo, M, Brown, LE, and Bottaro, M. Chest press exercises with different stability requirements result in similar muscle damage recovery in resistance trained men. J Strength Cond Res 31(1): 71–79, 2017—This study investigated the time course of 96 hours of muscle recovery after 3 different chest press exercises with different stability requirements in resistance-trained men. Twenty-seven men (23.5 ± 3.8 years) were randomly assigned to one of the 3 groups: (a) Smith machine bench press; (b) barbell bench press; or (c) dumbbell bench press. Participants performed 8 sets of 10 repetition maximum with 2 minutes rest between sets. Muscle thickness, peak torque (PT), and soreness were measured pre, post, 24, 48, 72, and 96 hours after exercise. There were no differences in the time course of PT or muscle thickness values of the pectoralis major (p = 0.98 and p = 0.91, respectively) or elbow extensors (p = 0.07 and p = 0.86, respectively) between groups. Muscle soreness of the pectoralis major was also not different between groups (p > 0.05). However, the Smith machine and barbell groups recovered from triceps brachii muscle soreness by 72 hours after exercise (p > 0.05), whereas the dumbbell group did not present any triceps brachii muscle soreness after exercise (p > 0.05). In conclusion, resistance-trained men experience similar muscle damage recovery after Smith machine, barbell, and dumbbell chest press exercise. However, muscle soreness of the elbow extensors takes a longer time to recover after using a barbell chest press exercise.

Abstract
Hughes, JD, Massiah, RG, and Clarke, RD. The potentiating effect of an accentuated eccentric load on countermovement jump performance. J Strength Cond Res 30(12): 3450–3455, 2016—Postactivation potentiation (PAP) following a bout of high-intensity exercise of short duration is known to produce both a fatigued and a potentiated state. There has been much research in the effectiveness of various PAP protocols, yet the type of dynamic muscle action utilized has seldom been investigated. Therefore, the present study aimed to assess whether an accentuated eccentric load (AE) could enhance subsequent performance. Eleven men (21 ± 2 years, 179.1 ± 6.9 cm, 83.2 ± 10.1 kg) performed 3 countermovement jumps (CMJs) before and 6 minutes after an AE and a back squat (BSq) PAP protocol. The participant's maximum CMJ height (cm) was determined before and after both protocol. A 2-way repeated measures analysis of variance was conducted to evaluate the effect of PAP condition and time on vertical jumping performance. A significant condition × time interaction was found (p = 0.02). Post hoc tests revealed that AE PAP had a significant (p = 0.03) potentiating effect on CMJ jump height. Whereas, the BSq PAP revealed no significant differences (p = 0.32). In conclusion, this study has shown that jump performance can be enhanced by eccentric muscle action when compared with a traditional BSq PAP protocol. This may provide a more practical method for coaches to enhance short-term explosive movements in athletic populations.

AbstractConstruction of next-generation sequencing (NGS) libraries involves RNA manipulation, which often creates noisy, biased, and artifactual data that contribute to errors in transcriptome analysis. In this study, a total of 19 whole transcriptome termini site sequencing (WTTS-seq) and seven RNA sequencing (RNA-seq) libraries were prepared from Xenopus tropicalis adult and embryo samples to determine the most effective library preparation method to maximize transcriptomics investigation. We strongly suggest that appropriate primers/adaptors are designed to inhibit amplification detours and that PCR overamplification is minimized to maximize transcriptome coverage. Furthermore, genome annotation must be improved so that missing data can be recovered. In addition, a complete understanding of sequencing platforms is critical to limit the formation of false-positive results. Technically, the WTTS-seq method enriches both poly(A)+ RNA and complementary DNA, adds 5′- and 3′-adaptors in one step, pursues strand sequencing and mapping, and profiles both gene expression and alternative polyadenylation (APA). Although RNA-seq is cost prohibitive, tends to produce false-positive results, and fails to detect APA diversity and dynamics, its combination with WTTS-seq is necessary to validate transcriptome-wide APA.

BackgroundThe strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting.ObjectiveThe aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for increased asthma severity.MethodsWe retrospectively reviewed the clinical charts of 72 patients who received a diagnosis of allergic occupational asthma, with or without associated occupational rhinitis.ResultsOur findings suggested that persistent asthma tended to be more common in subjects with associated occupational asthma and rhinitis, and occupational asthma severity was associated with occupational rhinitis severity. Moderate‐severe persistent occupational rhinitis is a risk factor for persistent occupational asthma.ConclusionsWe demonstrated, for the first time in the occupational setting, a significant association between occupational rhinitis and asthma severity.

ObjectivesOur prospective study aimed to elucidate the effect of long‐term experience of nonstandard employment status on the incidence of depression in elderly population using the Korean Longitudinal Study of Ageing (KLoSA) study.MethodsThis study used the first‐ to fourth‐wave cohorts of KLoSA. After the exclusion of the unemployed and participants who experienced a change in employment status during the followup periods, we analyzed a total of 1,817 participants. Employment contracts were assessed by self‐reported questions : standard or nonstandard employment. The short form of the Center for Epidemiologic Studies Depression Scale (CES‐D) served as the outcome measure. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox proportional hazards models to evaluate the association between standard/nonstandard employees and development of depression.ResultsThe mean age of the participants was 53.90 (± 7.21) years. We observed that nonstandard employment significantly increased the risk of depression. Compared with standard employees, nonstandard employees had a 1.5‐fold elevated risk for depression after adjusting for age, gender, CES‐D score at baseline, household income, occupation category, current marital status, number of living siblings, perceived health status, and chronic diseases [HR=1.461, 95% CI=(1.184, 1.805)]. Moreover, regardless of other individual characteristics, the elevated risk of depression was observed among all kinds of nonstandard workers, such as temporary and day workers, full‐time and part‐time workers, and directly employed and dispatched labor.ConclusionsThe 6‐year follow‐up study revealed that long‐term experience of nonstandard employment status increased the risk of depression in elderly population in Korea.

ObjectivesPatients with underlying conditions are at a higher risk of developing sepsis, a systematic response to infection, which has a high mortality rate. After the March 2011 Fukushima Daiichi nuclear power plant accident, there has been an influx of migrant decontamination workers; however, little is known about their health status.CaseA Japanese 55‐year‐old male decontamination worker, who had several underlying diseases, was transferred to our hospital in cardiopulmonary arrest. He had a history of diabetes mellitus and hypertension and a past history of tuberculosis. Control of underlying conditions was poor, with HbA1c of 13.8% at presentation. He was diagnosed with pneumonia‐induced bacteremia and sepsis due to Klebsiella pneumoniae. Although spontaneous circulation returned in emergency room, he died a day after admission.ConclusionThe poor control of underlying diseases seen in this patient could have been influenced by his recent job transfer and engagement in decontamination work and additionally related to his socioeconomic status (SES). This case highlights the need for further research to elucidate the underlying diseases, working conditions, and SES of this population.

Objective. The primary aim of this study was to quantify the prevalence of overweight and obesity among urban 7 - 10-year-old children in affluent (quintile 5) English-medium primary schools in Port Elizabeth.Method. A quantitative, descriptive one-way cross-sectional research design utilising random sampling was used. A once-off survey consisted of anthropometrical assessment of body mass index (BMI) according to standardised procedures. To classify children into weight categories, the International Obesity Task Force z-score BMI cut-off criteria were used. Post-hoc analysis consisted of one-way analysis of variance and χ2 tests. Level of significance was set at p<0.05. A total of 713 children participated in the study.Results. Overweight prevalence was 20.9% (n=149) and obesity prevalence was 9.8% (n=70). A significant interaction was found for overweight and obesity levels by gender and age (F=7.2, p=0.01). Of the boys (N=372) 18.5% (n=69) were overweight and 6.9% (n=26) were obese. The girls (N=341) had a 23.5% (n=80) overweight rate and 12,9% (n=44) were obese. The highest prevalence of overweight (24.7%, n=43, N=174) was found in children aged 10, and the highest prevalence of obesity (12.5%, n=21, N=167) was found in children aged 8. Conclusion. Results highlighted the rising prevalence of overweight and obesity among urban children from economically privileged settings. Future research into paediatric obesity is needed to curb the growing incidence.
Assessing Multiliteracies: Mismatches and Opportunities

Published: April 2016

While current literacy theories acknowledge the sociocultural and sociopolitical dimensions of literacy learning and teaching, that is, multiliteracies, there exists a gap between theoretical approaches underpinning literacy teaching and assessment. In this dialogue, we re-enact this divergence by collectively defining multiliteracies and deconstructing assessment practices, while speculating on possibilities for reconstruction. Constructing this dialogue across multiple areas of expertise exemplifies multiliteracies because we use critical speaking, listening, writing, reading, and representing, to make sense of our new understandings, and showcase our knowledge construction. Our goal is to explore ways to translate the theories of multiliteracies into assessment practices that make visible children’s cognitive-psychological, psycholinguistic, sociocultural, and sociopolitical processes with all kinds of texts.
