Association of transfusion transmitted infections with ABO and Rh D blood group system in healthy blood donors: a retrospective analysis

Blood transfusion is a lifesaving therapy in daily patient management. Every year millions of blood and its products are transfused across the world. Transfusion Transmitted Infections (TTI) especially hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) always pose threat to blood transfusion services. National AIDS Control Organization (NACO) guidelines on blood safety recommends mandatory testing for HIV 1 and 2, HBV, HCV, syphilis and malaria in all blood donor samples. It has been reported globally that around 33 million people are infected with HIV, 2 billion are infected with HBV, and 150 million are infected with HCV (3-4 million infections occur per year). There is high burden of syphilis infection globally, with an estimated 10.6 million incident cases occurring annually. Malaria is another ABSTRACT
Motivating styles in dual, initial vocational education and training

In Switzerland, individuals who follow the typical dual form of an initial vocational education and training (VET) programme to learn a trade do so at two main learning sites: a training company and a vocational school. In this context, apprentices’ motivations differ noticeably between the school and the training company. Based on the self-determination theory constructs of motivating styles, basic psychological needs, and autonomous versus controlled motivations, this study aims to understand how apprentices perceive their teachers’ and trainers’ motivating styles, control and autonomy support at the two learning sites. Three hundred and twenty apprentices provided written answers to open-ended questions. We coded the data using thematic analysis. While the exercise of control appeared to be rather similar at the two learning sites, autonomy support varied greatly. At the vocational school, autonomy support was expressed through teachers’ listening skills and availability; at the training company, it was related to independence and equal recognition of apprentices and employees. The apprentices perceived teachers as having a more controlled motivating style and in-company trainers as having a more autonomy-supportive style. At the school, control was described primarily as organisational pressure and teachers’ demands, whereas, at the training company, it was reflected in a lack of recognition and thankless tasks. We discuss the relationship between motivating styles and the satisfaction of basic psychological needs in the context of dual VET.
Testing and Validating DeLone and MacLean IS Model: ERP System Success in Higher Education Institutions of Pakistan

−The universities in Pakistan have recently started replacing their old legacy systems with ERP systems which are commonly used in business organizations to gain a competitive edge over competitors. The Higher Education Commission (HEC) has implemented ERPs systems at eight different universities of Pakistan. HEC has invested a huge amount of money to facilitate the integration, customization, and implementation of ERP systems in these universities. Previous studies have mainly focused on Critical Success Factors (CSFs) and risk factors of ERP systems. This study intends to empirically measure the support of ERP systems in teaching processes. DeLone and McLean model of Information Systems (IS) success is one of the most commonly used models cited in IS literature. In this study, DeLone and McLean model was applied at a University level analysis to access the impact of ERP in higher educational institutions and their support in the improvement of academic processes. Hypotheses were tested on the research model using empirical data collected from 230 respondents, including students and faculty at two selected universities, with the use of a questionnaire. The data were analyzed by structural equation modeling. The model was empirically tested and the findings showed that use and user satisfaction effected most net benefits. Information quality, system quality and service quality accounted for 42.6% effect in use. Whereas, information quality, system quality, service quality and use accounted for 46.5% variance in user satisfaction. Keywords-higher education; Enterprise Resource Planning (ERP) system; DeLone and McLean IS model
Circuit Model for the Effect of Nonradiative Recombination in a High-Speed Distributed-Feedback Laser

Based on single-mode rate equations, we present an improved equivalent-circuit model for distributed-feedback (DFB) lasers that accounts for the effects of parasitic parameters and nonradiative recombination. This equivalent-circuit model is composed of a parasitic circuit, an electrical circuit, an optical circuit, and a phase circuit, modeling the circuit equations transformed from the rate equations. The validity of the proposed circuit model is verified by comparing simulation results to measured results. The results show that the slope efficiency and threshold current of the model are 0.22 W/A and 13 mA respectively. It is also shown that increasing bias current results in the increase of the relaxation-oscillation frequency. Moreover, we show that the larger the bias current, the lower the frequency chirp, increasing the possibility of extending the transmission distance of an optical-fiber communication system. The results indicate that the proposed circuit model can accurately predict a DFB laser’s static and dynamic characteristics.
Antioxidant activities of Dichrostachys cinerea (L.) Wight et Arn (Leguminosae): Correlations between the Polyphenol Level and the Antioxidant Activity

Aims: Free radicals are involved in many diseases. Antioxidants help control them. The overproduction of free radicals or reduction of natural antioxidants promotes the destruction of cells in our body, for example in neurodegenerative diseases. The aim of our study is to evaluate the correlation between the level of polyphenol and antioxidant activity of Dichrostachys cinerea barks he work was carried out at the phytochemistry department of the Institute of Pharmacopoeia and Traditional Medicine (Gabon). Methodology: Different extracts of Dichrostachys cinerea barks were obtained with polarity solvent (dichloromethane, ethyl acetate, butanol, methanol and water). The antioxidant activity is evaluating using respectively FRAP method (Ferric Reducing Antioxidant Power), antiradical activity by the method of inhibition of DPPH radical (2.2-diphenyl-1-picrylhydrazyl), cations ABTS radical (2.2'-azinobis-[3-acid-6-sulfonic ethylenzothiazoline]). Original Research Article Samseny et al.; JOCAMR, 11(3): 1-11, 2020; Article no.JOCAMR. 61839 2 Results: Ethyl acetate and dichloromethane extract have the higher value for polyphenolic compounds, respectively 52,27±0,66 mg EAG / g and 49,72±0,55 mg EAG / g.

Towards End-to-end Deep Learning Analysis of Electrical Machines

Convolutional Neural Networks (CNNs) and Deep Learning (DL) revolutionized numerous research fields including robotics, natural language processing, self-driving cars, healthcare, and others. However, DL is still relatively under-researched in fields such as physics and engineering. Recent works on DL-assisted analysis showed emerging interest and enormous potential of CNN applications. This paper explores the possibility of developing an end-to-end DL pipeline for the analysis of electrical machines. The CNNs are trained on conventional finite element method (FEA) data to predict the output torque curves of electric machines. FEA is only used for dataset collections and CNN training, whereas the analysis is done solely using CNNs. The required depth in CNN architecture is studied by comparing a simplistic CNN with three ResNet architectures. The effects of dataset balancing and data normalization are studied and torque clipping inspired by offset normalization is proposed to ease CNN training and improve the prediction accuracy. The relation between architecture depth and accuracy is identified showing that deeper CNNs improve the curve shape prediction accuracy even after torque magnitude prediction accuracy saturates. Over 90% accuracy for analysis conducted under a minute is reported for CNNs, whereas FEA of comparable accuracy required 200 hours. Predicting multidimensional outputs can improve CNN performance, which is essential for multiparameter optimization of electrical machines.
A Method of Measuring Uncertainty for Z-Number

Z-number is a new framework of fuzzy sets that combines with constraint and reliability. Managing the uncertainty of Z-number is an important issue in the fuzzy decision making of Z-number based. In this paper, we first develop a new uncertainty measure of fuzzy set considering the influence of fuzziness measure and the range (or cardinality) of the fuzzy set. Some properties of the developed uncertainty measure of the fuzzy set are presented. We then propose and discuss method of measuring the uncertainty of Z-number. Examples are used to illustrate the effectiveness of the proposed methodologies.
Kinetic study of the reaction between molybdenum trioxide and gaseous carbon tetrachloride

The kinetics of the chlorination reaction of molybdenum trioxide with gaseous carbon tetrachloride has been studied at temperatures between 713 and 753 K. The effects of temperature, reaction time, residence time and gaseous reactant concentration on conversion were studied throughout the reaction. In all cases, there was an increase in conversion when the above operating variables were increased. The kinetic model proposed is consistent with and correlates the experimental data. In the range studied for the different variables, the step that controls the rate of reaction is the surface chemical reaction. Values of the rate constant and the activation energy were estimated.

Post Operative Pain Management Knowledge, Attitude, Practice and Associated Factors Regarding Among Nurses’ Working in Jimma Medical Center, South-West Ethiopia, 2019

Introduction: Effective post-operative pain management can lead to comfort, better mobility, improved recovery, and shorter stay in hospital. However, though few studies were done in this area, the extent to which nurses practice post-operative pain management and their level of knowledge and attitude regarding pain is not well documented in the study setting. Objective: To assess post-operative pain management knowledge, attitude, practice and associated factors among nurses working at Jimma medical center, south-west Ethiopia, 2019. Methods: Institution based quantitative cross-sectional study design was conducted on 203 nurses working in surgical Gynecology maternity and labor ward, operation theater, ophthalmology units of Jimma Medical Center. Data was collected by using pretested structured self-administered questionnaire and entered SPSS version 21 for analysis. Descriptive statistics (frequency percentage mean and standard deviation) was computed. Chi-square test was done to determine the association between dependent and independent variables. Significant associations were declared at P value less than 0.05. Results: The finding of this study revealed that 88.8% of nurses had poor knowledge and attitude regarding pain and 23.5% had good post-operative pain management practice. Prior training on pain management and reading of medical books were significantly associated with knowledge and attitude regarding pain whereas working unit and prior training on pain were found to be significantly associated with post-operative pain management practice. Conclusion and recommendation: Nurses knowledge and attitude regarding post-operative pain management practice in Jimma Medical Center are generally low. Prior training and reading books are significantly associated with the level of nurses’ knowledge and attitude whereas; training and working units are significantly associated with post-operative pain management practice. Jimma Medical center should provide an in-service training and avail reading books to improve nurse’s knowledge, attitude and practice toward post-operative pain management.
Study the effects of factors on the structure and phase transition of bulk Ag by molecular dynamics method

This paper studies the effect of atoms number [Formula: see text] of bulk Ag: [Formula: see text] atoms (Ag[Formula: see text]), 4000 atoms (Ag[Formula: see text]), 5324 atoms (Ag[Formula: see text], 6912 atoms (Ag[Formula: see text] at temperature [Formula: see text][Formula: see text]K, 400[Formula: see text]K, 500[Formula: see text]K, 600[Formula: see text]K, 700[Formula: see text]K, 800[Formula: see text]K, 900[Formula: see text]K, 1000[Formula: see text]K on bulk Ag[Formula: see text] and annealing time [Formula: see text] = 200 ps on the structure and phase transition of Ag bulk by Molecular Dynamics (MD) method with Sutton–Chen (SC) pair interaction potential, periodic boundary conditions. The structural results are analyzed through the Radial Distribution Function (RDF), the total energy of the system ([Formula: see text], the size [Formula: see text], the phase transition (determined by the relationship between [Formula: see text] and [Formula: see text]), and combined with the Common Neighbors Analysis (CNA) method. The obtained results show that the first peak’s position ([Formula: see text] of the RDF has negligible change value, [Formula: see text][Formula: see text]Å, which is completely consistent with the experimental results. For bulk Ag, there are always four types of structure: FCC, HCP, BCC, Amor and glass transition temperature [Formula: see text][Formula: see text]K. When decreasing the temperature, bulk Ag changes from liquid state to crystalline state, when increasing the annealing time at [Formula: see text][Formula: see text]K, bulk Ag changes from amorphous phase to crystalline phase state, leading to the increase of FCC, HCP, BCC structures and the decrease of Amor structure. The obtained results will be used as guide for future experiments.
People Behavior Related To The Spread Of Covid-19’s Hoax

Covid-19 became the biggest non-natural disaster in the world in 2020. It first broke out in Wuhan, China, and then spread to other countries including Indonesia. The public is in uncertainty and receives a lot of information about Covid-19 through various media. This condition is exacerbated by the spread of hoax related to Covid-19 which is difficult to contain. The purpose of this study was to analyses society's behavior related to the spread of the Covid-19 hoax. This research uses a survey method with a quantitative approach. The results of the study concluded that respondents' knowledge about Covid-19 and hoax was very adequate. However, most respondents are hesitant and are in a position that can sometimes distinguish hoax, sometimes not because of the large amount of information obtained every day. The public panic at Covid-19 caused hoax to continue to be spread in the hope that the information could be useful in preventing and treating. While the respondents did not spread Covid's-19 hoax, because they considered the information to be incorrect, not useful, and harmful to the health of others, and they wanted to break the chain of hoax distribution to themselves.
Molecular packing handedness dominated by the chirality of the lactic acid residue near the liquid crystalline core

ABSTRACT Eight dichiral compounds containing two lactic acid residues and one perfluorocarbon chain are synthesised. Six of them are liquid crystals with an enantiotropic SmA phase. Two of them are liquid crystals with enantiotropic SmA and SmC* phases. Although (R,R)-3 and (R,R)-4 molecules pack in monolayer structures at the crystalline states, (S,R)-3 and (R,S)-4 molecules pack in bilayer structures at the crystalline states. The optical activity of these compounds is mainly controlled by the chirality of the lactic acid residue near the liquid crystalline core. The dichiral compounds can self-assemble into nanotubes or twisted nanoribbons in methanol. Circular dichroism characterisation indicated that the stacking handedness of the liquid crystalline cores in the organic self-assemblies was also dominated by the chirality of the lactic acid residue near the liquid crystalline core.

Sanctuary Policy Adoptions: Assessing the Effects of Ideology and Access to Labor and Housing Markets

Sanctuary policies are generally explained as the outcome of a conflict between desires for openness and restrictionist impulses. In this view, economic factors are exogenous forces that interact with ideological commitments. In contrast, we contend that some of these economic factors follow from ideological commitments and are therefore not exogenous forces. The economic factors follow from ideology because governments that choose to enact sanctuary policies also favor higher levels of land-use and labor-market regulation. We show that: (1) declines in the relative size of the non-citizen population pre-date the sanctuary policies and are confined to counties that ultimately adopt the sanctuary policies; and (2) reduced access to housing and labor markets predicts both sanctuary policy adoption and negative changes in the relative size of the non-citizen population. Thus, the outcomes from policy choices of left-of-center governments on land-use and labor-market regulation directly contravene the apparent purpose of the sanctuary policy.

Preliminary Diagnostic of the Tourist Potential of a Heritage Town in Colombia

ABSTRACT A tourism planning process is a valuable tool that allows us to anticipate the problems that the activity generates in local destinations. Therefore, the present study is based on a proposal of the preliminary diagnosis of the tourist potential of the Colombian municipality of La Playa de Belén. This town is home to a unique lush natural park as well as an unparalleled historical center of the country. Moreover, its total tourism potential is currently little known. The results of the diagnosis showed the potential for the development of rural tourism. Tourism is a crucial economic in studied area stake based on the political perspective of the local administration. Likewise, the tourist inventory allowed the identification of thirty-two tourist resources. Most of them are cultural heritage, showing in addition to the natural wealth, and new tourist specialties could potentialize in this municipality in the Colombian northeast.
Differences in anthropometric and physical performance characteristics between U17, U19, and Senior Irish female international football players

This study aimed to compare the anthropometric physical performance characteristics of Irish female international footballers at U17, U19, and Senior age groups. Fifty-five (U17, n =24, U19, n =21, Senior, n = 10) female international football players participated in this study. The subjects underwent anthropometric measurements (height and body mass) and physical performance tests countermovement jump (CMJ), reactive strength index (RSI), 10-m, 20-m, 30-m linear sprint, and yo-yo intermittent recovery test level 1 (YYIR1). No significant differences were identified between any age groups for the anthropometric measures of height and body mass. Concerning the physical tests, senior players displayed greater CMJ scores in comparison with the U17 (P = 0.040). Senior players also possessed higher levels of reactive strength with large effect sizes present (ES = 0.83 - 0.92) in comparison to all age groups. No significant differences were identified between any of the age groups across the 10-m, 20-m, 30-m, and rolling 20-m linear speed assessments. Senior players covered the greatest distance in the YYIR1 (P = 0.0001) versus the U19 and U17. These results indicate there was no difference in the anthropometric profile of the age groups assessed. However, differences in physical performance characteristics were present between age groups, thus suggesting improvements in lower limb power and aerobic endurance are achievable in adulthood as players physically mature.
Genetic diversity of ten Moroccan populations of Tetraclinis articulata as revealed by Inter Simple Sequence Repeat (ISSR) markers

Tetraclinis articulata (Vahl) Masters is one of Morocco's most important forest species. It is also found occasionally in Malta and Spain, showing significant adaptability to different bio-climatic conditions. However, the species is being affected by anthropogenic fragmentation, logging and neglect from authorities, which could lead to the irretrievable loss of this resource. In this study, the genetic diversity and genetic structure of ten Moroccan populations of T. articulata were assessed. Fifteen Inter-Simple Sequence Repeat (ISSR) markers were used. These generated 271 polymorphic fragments with an average of 18.06 per primer and showed 79.59% of polymorphism. The 129 individuals revealed a high level of genetic diversity (Hs = 0.221; Ht = 0.254) and 85% of genetic variation within populations. However, the genetic differentiation level was low (Gst = 0.13), which is consistent with the lack of correlation between genetic and geographic distances revealed by the Mantel test, resulting in a high level of gene flow (Nm = 3.294). Based on PCoA and neighbour-joining methods, the ten populations clustered under the effect of continental and marine climates. Compared with other conifers, the current genetic diversity and the pattern of T. articulata population structure indicate an important gene pool requiring efficient conservation strategies.
