Persistence of traditional and emergence of new structural drivers and factors for the HIV epidemic in rural Uganda; A qualitative study

Background In Uganda, the HIV epidemic is now mature and generalized. Recently, there have been reports of resurgence in the incidence of HIV after several years of successful control. The causes for this resurgence are not clear but suspected to be driven by structural factors that influence large groups of people rather than individuals. The aim of this study was to describe the structural drivers of the HIV epidemic and inform the next generation of interventions. Methodology We conducted a total of 35 focus group discussions in 11 districts in Uganda. Focus groups consisted of men and women including opinion leaders, civil servants including teachers, police officers, religious, political leaders, shop keepers, local residents and other ordinary persons from all walks of life. The qualitative data were transcribed and analyzed manually. Texts were coded using a coding scheme which was prepared ahead of time but emerging themes and codes were also allowed. Results Our data indicated there is persistence of several structural drivers and factors for HIV in rural Uganda. The structural drivers of HIV were divided into three categories: Gender issues, socio-cultural, and economic drivers. The specific drivers included several gender issues, stigma surrounding illness, traditional medical practices, urbanization, alcohol and substance abuse and poverty. New drivers arising from urbanization, easy access to mobile phone, internet and technological advancement have emerged. These drivers are intertwined within an existing culture, lifestyle and the mixture is influenced by modernization. Conclusion The traditional structural drivers of HIV have persisted since the emergence of the HIV epidemic in Uganda and new ones have emerged. All these drivers may require combined structural interventions that are culturally and locally adapted in order to tackle the resurgence in incidence of HIV in Uganda.
Reducing the vibration of bearing units of electric vehicle asynchronous traction motors

The impact of the accuracy class of bearings, rotational speed, load, clearances, and fits on the vibration levels of electric motor bearing units is investigated. The ways to reduce the vibrations of mechanical origin are offered. The boundary vibration levels of asynchronous motors limited by vibration levels of 40 dB at a frequency of 5 Hz and 80 dB at a frequency of 10,000 Hz are determined. The effect of increasing the rotational speed and load on the vibration levels of bearing units has been determined, and reserves for reducing vibration while ensuring the optimum bearing preload on the shaft journal have been identified. It is established that the clearance between the cap and the bearing when it is fixed in the housing (primer) does not ensure the unambiguity of the bearing unit assembly, which results in a large variation in vibration levels compared with rigid and elastic fixation. The results of this research can be applied to all types of traction electric motors.
Radiation Defects in Lime Mortars and Plasters Studied by EPR Spectroscopy

ABSTRACT Electron paramagnetic resonance (EPR) spectroscopy is a well-established method of dating based on trapped charges, applied to various crystalline materials, including carbonates, bones, and teeth. It provides a detailed insight into the structure of radiation defects—paramagnetic centers generated by irradiation, without the need of a painstaking sample preparation, often challenging in other methods. Using EPR we studied the effect of γ radiation on lime mortars and plasters from ancient settlement Hippos in Israel, in order to analyze the process of defect generation. Analysis of the complex spectra revealed the presence of radiation-induced species, including CO2–, NO32– and organic radical. Using an artificial UV source, we generated relatively strong signals of paramagnetic centers, analogous to those created by γ irradiation, reaching their maximum intensity after 5–6 hr of UV exposure. Our results confirm the previous reports that radiation defects can also be generated, instead of bleached, in calcite by UV radiation, which is crucial for identifying the issues related to light exposition, affecting the accuracy of age determinations in trapped-charge dating methods.
An updated checklist of the bees (Hymenoptera, Apoidea, Anthophila) of Pennsylvania, United States of America

Checklists provide information about the species found in a defined region and serve as baselines for detecting species range expansions, contractions, or introductions. Bees are a diverse and important group of insect pollinators. Although some bee populations are declining, these patterns are difficult to document and generalize due to a lack of long-term studies for most localities. Documenting the diversity of wild bee communities is critical for assessing pollination services, community ecology, and geographical and temporal changes in distribution and density. Here, an updated checklist of the bees of the Commonwealth of Pennsylvania, USA, is presented. Since the first checklist was published (2010; 372 species), thousands of additional specimens from the state have been collected and databased, new species have been described in the region, and the taxonomic status of some species have changed. Specimen data from insect collections, databases, scientific literature, and unpublished records were compared to the original checklist. Seventy-nine new state species records – including 49 first-time reports – representing five of the six bee families in North America, were documented resulting in a total of at least 437 bee JHR 77: 1–86 (2020) doi: 10.3897/jhr.77. 49622 http://jhr.pensoft. net Copyright Shelby Kerrin Kilpatrick et al.

CHECKLIST Shelby Kerrin Kilpatrick et al. / Journal of Hymenoptera Research 77: 1–86 (2020) 2 species reported from Pennsylvania. We highlight new county records and species persistence details. Our list includes a total of 23 exotic species and at least five species of conservation concern. Lists of species excluded from the state checklist and species anticipated to occur in Pennsylvania are also included. This checklist provides baseline data for researchers and the public. The benefits of insect collections, specimen databases, determination and voucher labels, and georeferencing to biodiversity studies and other aspects of biological research are also discussed.
Pore Structure Characteristics and Gas Storage Potential of the Cretaceous La Luna Formation, Middle Magdalena Valley Basin, Colombia

The rocks of interest in the present study (mudstones) show inherently a heterogeneous pore-size distribution in the matrix. They can present organic and inorganic pores and the transport mechanism through pores is different, and, therefore, it is necessary to describe their organic and inorganic porosity. This work uses different microscopy techniques to characterize mudstones from the Galembo Member of the Cretaceous La Luna Formation, Middle Magdalena Valley Basin, Colombia. These rocks present several pore types, including interparticle pores due to flocculation of clay minerals, organoporosity due to burial and thermal maturity, intraparticle pores from organisms, intraparticle pores within mineral grains, and microchannels and microfractures. The existence of interconnected pores in such complex fracture-pore system provides effective pathways for primary gas migration and it also provides a storage space for the residual hydrocarbon in mudstones, which is important for the primary migration and storage in gas reservoir rocks. The pore connectivity is high and increases towards the top of the sedimentary sequence.

Two variables are used as control variables, which are company age and company leverage. The samples in this research is taken by random sampling method among public company listed in Indonesia Stock Exchange (IDX) consisting of 266 companies with research period for 7 years from 2011 until 2017. The results show that age, family relation as a board of commissioners, and activities of the board of commissioners have no significant effect on company value. Meanwhile, company age and company leverage have negative and significant effect on company value.
Problematic gambling behaviour in adolescents: prevalence and its relation to social, self-regulatory, and academic self-efficacy

ABSTRACT A non-random sample of 560 Italian high school students completed a questionnaire consisting of demographic items and questions about gambling behaviour, motivations, and perceived social, self-regulatory, and academic self-efficacy. Among these participants, 49 of them were classified as at-risk gamblers, 21 as problem gamblers, and the rest as non-at-risk/problem gamblers or non-players. Chi-square tests showed that gambling, several game types, some motivations to gamble, and at-risk/problem gambling were more common among males than females. Logistic regression was employed to predict the risk of being an at-risk/problem gambler and results showed that medium and high levels of self-efficacy halves this risk; however, the halving of the risk was not statistically significant with respect to perceived academic self-efficacy. It was concluded that the three forms of self-efficacy taken into consideration can be protective factors for at-risk/problem gambling.
Production of Glucoamylase, α-amylase and Cellulase by Aspergillus oryzae F-923 Cultivated on Wheat Bran under Solid State Fermentation

Filamentous fungi have been widely utilized in production of enzymes which have many industrial applications. In this study, twenty five local fungal isolates, belonging to Aspergillus sp. , Trichoderma sp. and Penicillium sp. , were screened under solid state fermentation conditions (SSF) for the production of α-amylase, glucoamylase and cellulase. Asperigillus oryzae F-923, cultivated on wheat bran, was the most promising isolate for production of the target enzymes under this study. Physical parameters of moisture content, pH, temperature and incubation time, optimized were 1:2(w/v), 5.5, 28°C and 72 hr, respectively. The production of enzymes was enhanced when ammonium sulfate was supplemented as a nitrogen source to wheat bran. The production of α-amylase and glucoamylase was also enhanced when 10% (w/w) soluble starch was added as a carbon source to wheat bran. However xylose supplementation at 10% (w/w) was observed to be best for cellulase production. Tap water was found to be efficient for enzymes' Original Research Article Fadel et al.; JABB, 23(4): 8-22, 2020; Article no.JABB. 58348 9 extraction from the fermentation medium. Three successive extractions were needed to obtain the produced enzymes from the fermented substrate. Characterization of the produced enzymes revealed that, the optimum temperature for α-amylase and glucoamylase was 60°C, while 50°C was the optimum temperature for cellulase activity. Isopropanol 1:1(v/v) was proved to be more suitable for partial purification of enzymes. Following partial purification of enzymes of glucoamylase, α-amylase and cellulase increased to 10.8, 11.8 and 11.4 folds, respectively.
Job strain, gender and well-being at work: a case study of public sector line managers

The purpose of this paper is to further the understanding of public sector line managers' work-related well-being and health in relation to job strain, gender and workplace social support. ,An online survey was sent to all senior and middle line managers (N = 357) in three administrative departments of Iceland's largest municipality. The response rate was 64.7%. Multivariate logistic regression was used to analyse the data. ,A minority of respondents experience high job strain. However, for these managers, the risk of experiencing emotional exhaustion is about fivefold, compared to those not experiencing high job strain. Social support is an important buffering against job strain and enhances well-being. Female managers are more likely than their male counterparts to report myositis, back or shoulder pain and sleeping difficulty. ,The study emphasises that workplace social support attenuates the negative impact of job strain on line managers' work-related well-being. Furthermore, it demonstrates that in a society at the forefront in gender equality, gender differences in health symptoms exist among line managers in the public sector – a finding that highlights the importance of studying all aspects of workplace well-being by gender. This calls for future research using a more comprehensive survey data and interviews to shed light on the pathways through which female line managers' health is negatively affected. ,Knowledge relating to well-being and health of line managers in the public sector is scarce. This study contributes to filling that gap. As work-related well-being is often gender-blind, the value of the study is also the investigation of the gender patterns in the authors’ data.
Factors Used to Determine the Financing Structure for Shareholding Companies Listed in Amman Stock Exchange in Jordan

Purpose – This study aims to explore the main factors that could be used to determine the financing structure for companies listed in Amman Stock Exchange in Jordan. The hypotheses were developed in light of three theories relating financing structure, trade-off theory (TOT), agency theory and pecking order theory (POT). Design/methodology/approach – The study using unbalanced panel data sample applying regression models for two-dimensions combines cross-sectional and time series for non- financial Jordanian companies listed in ASE over the period 2014–2018. Using standard models include entering a fixed effect, random effect, or not using any effect. Findings - The findings showed that company size, growth opportunities, and tax-deductible items other than interest have a positive effect on the borrowing, but profitability affects negatively on borrowing. These results are consistent with the arrangement theories (trade-off theory (TOT) and pecking order theory (POT). indicating the factors associated with trade-off theory were stronger than what is usually found in developed countries, and this is an indication of deep problem resulted from asymmetry information in the Jordanian market. which require to focus efforts on how to building the confidence with investors by providing the data that serve them in decision making.

The Effect of Consumer Motivations on Purchase Intention of Online Fashion - Sharing Platform

This study aims to examine the influence of attitudes on customers’ intention to participate in online fashion sharing. A framework was proposed to investigate the relationships between consumer motivation, consumer attitude, and purchase intention in the manner of adopting a fashion-sharing platform. Consumer motivations are divided into three categories: utilitarian, hedonic, and ecological. The moderating effects of product replacement cycle (PRC) on consumer attitude and purchase intention are also investigated. Data collection was developed using a web-based survey where 180 consumer respondents from South Korea participated. The results of our analysis indicate that consumers’ hedonic and ecological motivations are positively related to favorable consumer attitudes, even when consumers’ utilitarian motivation is denied. Consumer attitude is also positively related to purchase intention in the fashion-sharing platform. A moderating effect of PRC is recorded between consumer attitude and purchase intention based on high and low PRC, as well as the effect of ecological motivation and consumer attitude on high PRC. This study enhances knowledge of consumer motivational factors in a fashion-sharing platform and provides insights for service providers to help them improve their target marketing.
Fgf3 is crucial for the generation of monoaminergic cerebrospinal fluid contacting cells in zebrafish

ABSTRACT In most vertebrates, including zebrafish, the hypothalamic serotonergic cerebrospinal fluid-contacting (CSF-c) cells constitute a prominent population. In contrast to the hindbrain serotonergic neurons, little is known about the development and function of these cells. Here, we identify fibroblast growth factor (Fgf)3 as the main Fgf ligand controlling the ontogeny of serotonergic CSF-c cells. We show that fgf3 positively regulates the number of serotonergic CSF-c cells, as well as a subset of dopaminergic and neuroendocrine cells in the posterior hypothalamus via control of proliferation and cell survival. Further, expression of the ETS-domain transcription factor etv5b is downregulated after fgf3 impairment. Previous findings identified etv5b as critical for the proliferation of serotonergic progenitors in the hypothalamus, and therefore we now suggest that Fgf3 acts via etv5b during early development to ultimately control the number of mature serotonergic CSF-c cells. Moreover, our analysis of the developing hypothalamic transcriptome shows that the expression of fgf3 is upregulated upon fgf3 loss-of-function, suggesting activation of a self-compensatory mechanism. Together, these results highlight Fgf3 in a novel context as part of a signalling pathway of critical importance for hypothalamic development. Summary: This study highlights Fgf3 in a novel context where it is part of a signalling pathway of critical importance for development of hypothalamic monoaminergic cells in zebrafish.
Influence of branched chain amino acids on insulin sensitivity and the mediator roles of short chain fatty acids and gut hormones: a review

Circulating levels of branched chain amino acids (BCAAs) correlate strongly with type 2 diabetes (T2D). The correlation may be associated with insulin-resistance factors independent of glycemic markers currently used in the diagnosis and monitoring of diabetes. This can revolutionize the thought process and methodology not only in diabetes treatment, but also in its advance screening and prevention with BCAAs used as biomarkers and targets for treatment. Whether insulin resistance is the cause or result of BCAAs imbalances requires further investigation. Although the overall diet is important, the role of specific diets targeting the gut microbiome composition and hormone secretion affecting BCAA absorption and metabolism will be explored. Generic diet modifications apparently induce only negligible changes in the intrinsic genetic make-up of the gut and BCAA levels but influence specific modulation of the gut microbiome. This genetic make-up is indeed similar among T2D patients independent of numerous variables including obesity. Short-chain fatty acids (SCFAs), the primary end-products of non-digestible carbohydrates (NDC) fermentation, mediate metabolic imbalances through gut microbiota and gut hormone secretion. This review focuses on extensive evidence gathered using diverse methodologies on the strong parallel correlation between BCAA levels and insulin resistance. Furthermore, the role of specific diets particularly SCFAs as mediators of the stubbornly fixed intrinsic genetic make-up of gut microbiota will be scrutinized to delineate BCAA levels and insulin resistance in T2D.
Modified Dijkstra's Routing Algorithm for Security with Different Trust Degrees

A great number of efficient methods to improve the performance of the networks have been proposed in physical-layer security for wireless communications. So far, the security and privacy in wireless communications is optimized based on a fixed assumption about the trustworthiness or trust degrees (TD) of certain wireless nodes. The nodes are often classified into different types such as eavesdroppers, untrusted relays, and trusted cooperative nodes. Wireless nodes in different networks do not completely trust each other when cooperating or relaying information for each other. Optimizing the network based on trust degrees plays an important role in improving the security and privacy for the modern wireless network. We proposed a novel algorithm to find the route with the smallest total transmission time from the source to the destination and still guarantee that the accumulated TD is larger than a trust degree threshold. Simulation results are presented to analyze the affects of the transmit SNR, node density, and TD threshold on different network performance elements.
