Authors: Janssen Ricky , Krumeich Anja , Esmail Aliasgar , Thomas Réjean , Dheda Keertan , Pant Pai Nitika , Engel Nora
Published: November 2021

Feasibility and acceptability research for HIV self-testing (HIVST) often emphasises the importance of good test conduct and correct test interpretation for knowing one’s HIV result while overlooking the ways in which different uncertainties and meanings emerge around testing. Using empirical examples from a quantitative study assessing an app-based strategy in Cape Town, South Africa, this research article explores the practice of HIVST and how people deal with uncertainties while using the app in question, named ‘HIVSmart!’. We use the concept of ‘living under’ to explore the practices of HIV testing for those who fit the definition of being ‘at risk’ of HIV (note that an individual’s HIV status must be unknown in order for them to fit this definition) and to understand how an app-based HIVST strategy fits within these practices. We show how the app and oral self-test—as well as knowledge around HIV risk behaviours, comparisons between different testing methods, and the guidance and presence of healthcare staff—alleviate as well as generate uncertainty and constitute HIV status as an ongoing process. The effective implementation of new strategies for HIVST requires consideration of multiple aspects of the testing process, including local understandings of HIV risk, access to healthcare staff, and the meaning of certain test methods within a particular context.

Published: November 2021

Mediterranean flour moth Ephestia kuehniella (Zeller, Lepidoptera: Pyralidae) is one of the most important insect pests that invade the stored grain of many grains around the world. Chemical control is a very preferred method in the fight of this pest. However, due to the economic, social and environmental damages of chemicals, the interest in biological control, which is an alternative method, is gradually increasing. Entomopathogens have very important in biological control and that cause desired infections in pests. Entomopathogens include many species such as viruses, bacteria, protists, fungi and nematodes. In recent years, entomopathogeic nematodes; Steinernema feltiae, Steinernema carpocapsae, Steinernema riobrave, Heterorhabditis bacteriophora, Heterorhabditis sp., Steinernema sp., and Xenorhabdus nematophila, entomopathogenic fungi; Paecilomyces fumosoroseus (=Isaria fumosorosea), Beuveria bassiana and Metarhizium anisopliae, entomopathogenic bacteria; Bacillus thuringiensis subsp. kurstaki, Photorhabdus temperata and Bacillus subtilis, entomopathogenic protists; Vairimorpha ephestiae, Leidyana ephestiae, Mattesia dispora and Mattesia oryzaephili, and virus; Nuclear Polyhedrosis Virus (NPV) were reported from E.kuehniella. In this review, it is aimed to evaluate the recent status of these entomopathogenic organisms found or tested for E. kuehniella

Authors: Kulagina I.Y. , Apasova E.V. , Fyodorov V.V.
Published: November 2021

The article describes the development of a diagnostic tool for determining the level of learning motivation in primary school children. The questionnaire developed by the authors includes 4 scales: negative attitude towards full-time schooling, demonstration of competence, positive attitude towards school life, and social significance of learning as a value. The study was carried out on a stage-by-stage basis and involved 352 students of 3—4 grades of Moscow schools in the first stage and 364 students in the second. The first stage allowed us to select 15 out of 33 judgments which differentiate the answers of children the most. These judgments made up the final version of the questionnaire which was used in the subsequent stages of the study. Standardization of the questionnaire showed the internal consistency of its scales and the correspondence between the indicators of motivation obtained in the test and the expert assessments of teachers. The results obtained in the study demonstrate construct validity and reliability of the “Learning Motivation Level” questionnaire. The developed technique can be used for monitoring purposes in primary schools in order to study and assess children’s motivation and needs, in counseling and research practice, and for assessing the effectiveness of various educational programs.

Published: November 2021

Objective: Healthcare workers (HCWs) are among the highest groups impacted by the COVID-19 pandemic. This study aimed to analyze professional quality of life (ProQOL) and its association with emotional well-being in HCWs during the pandemic.
Methods: This cross-sectional study was conducted on HCWs being in close contact with COVID-19 patients in Iran. The questionnaires assessing ProQOL, emotional well-being, and demographic and occupational characteristics were recruited via email or social media. The ProQOL was used to measure compassion fatigue (CF), burnout (BO) and compassion satisfaction (CS).
Results: Among the respondents, 705 HCWs were enrolled, including a higher proportion of physicians 449 (63.7%), females 452 (64.1%), and married 486 (68.9%). The mean of participants’ work experience was 8.41 ± 8.91 years. Almost all of HCWs showed moderate to high levels of CS (98.3%). Also, most of HCWs showed a moderate level of CF (96.3%), and the majority of them (76.6%) had a moderate level of BO. There were significant differences in the duration of contact with COVID-19 patients for all three components of ProQOL and emotional well-being score. Women had a higher level of BO than men (P=0.003). CS was significantly higher in married HCWs than in singles (P=0.007). Pearson correlation coefficient showed that CS had a negative relationship with CF and BO. However, there was a direct correlation between emotional well-being and the CS.
Conclusion: During the COVID-19 pandemic, Iranian HCWs showed to have moderate to high levels of CS, and a moderate level of both CF and BO, and showed that emotional well-being had a direct correlation with CS.

Objective: The main objective of this study is to evaluate the prevalence of risk factors for and demographics of patients younger than 65 years old with stroke.
Methods: This retrospective cross-sectional study took into consideration all patients younger than 65 years old who were admitted to the emergency department from 2016 to 2018. Some significant criteria such as age, sex, type of stroke, stroke risk factors, and modified Ranking Scale (mRS) were extracted from patients’ medical records. Based on their age, these patients were divided into three groups: younger than 35 years old (Group A), between 35-50 years old (Group B), and older than 50 years old (Group C). Data analysis was carried out using IBM® SPSS® Statistics 20.0 software.
Results: A total of 392 patients with stroke were included in this study. Groups A, B, and C included 31, 124, and 237 patients, respectively. Among them, 313 patients (79.84%) were admitted to the hospital in cold seasons, while 73 patients (18.6%) had no symptoms related to stroke at the time of admission. The most common adjustable risk factor among the patients was hypertension (HTN) with a frequency of 230 (58.7%). Of note, the frequency of HTN, diabetes, atrial fibrillation (AF), oral contraceptive pill (OCP) consumption, and coronary artery disease (CAD) in patients was significantly different among these three groups.
Conclusion: According to the findings of the present study, the prevalence rate of stroke probably varies for male and female (gender) in the studied groups, which is significantly correlated with age. Among the adjustable risk factors for stroke, HTN, diabetes, AF, OCP consumption, and CAD are significantly correlated with the age.

Mucormycosis is an opportunistic fungal infection that occurs primarily in immunocompromised individuals, usually affecting the rhino-orbital areas followed by the lungs. This case report presents renal mucormycosis in a young man after COVID-19 pneumonia that escalates the need for regular follow-up of COVID-19 patients. Post-COVID-19 fungal infections are on a steep rise, and the increased use of steroids and immune modulators for COVID-19-associated immune dysregulation and cytokine syndrome increases the risk among patients treated for COVID-19.
OPTIMIZATION OF A PIEZOELECTRIC GENERATOR OF FLEXURAL VIBRATIONS WITH AN ACTIVE PIEZOMAGNETIC LAYER BASED ON A COMBINATION OF THE FINITE ELEMENT METHOD AND A GENETIC ALGORITHM
Authors: Do Thаnh Binh
Published: November 2021

The construction of the piezoelectric generator (PEG) for the energy storage device has a significant effect on the electromechanical conversion characteristics, and the optimal choice of its geometric parameters is an important prerequisite for ensuring efficiency of the electromechanical conversion. This article discusses a PEG model based on circular three-layer plate in the ANSYS package. Two piezoactive layers, piezoelectric and piezomagnetic, are glued to a steel substrate. The program built in the MATLAB package allows to control ANSYS scripts to find the dependence of the electromechanical coupling coefficient on the geometric parameters of the object. The genetic algorithm is used to determine the maximum value of the electromechanical coupling coefficient when changing the radius and thickness of the layers within certain limits. Thus, a set of geometric dimensions is determined to achieve the best PEG energy conversion efficiency. After applying the optimization algorithm, the electromechanical coupling coefficient increases by 34% in comparison with the results of previous studies.
Implementation of the new WHO recommendations on HIV and infant feeding: Challenges and the way forward

Published: November 2021

Breast milk provides all the nutrient needs of the infant especially in the first six months of life and also protects the growing infant from pneumonia, diarrhoea, and malnutrition, which are the major causes of morbidity and mortality in the African Region. However breastfeeding is also known to transmit the Human Immunodeficiency Virus (HIV) from mother to the child. Several guidelines have been developed to guide policy makers, health workers and mothers on the most appropriate methods to feed HIV exposed infants. Previous HIV and infant feeding guidelines emphasized on preventing infants from becoming infected with HIV by counseling HIV-infected mothers to avoid all breastfeeding. Over the period, programme implementers and researchers have reported difficulties in implementing earlier recommendations and guidelines on HIV and infant feeding within health-care systems. New evidence now shows that giving Anti-Retroviral therapy (ARVs) to either the HIV-infected mother or HIV-exposed infant can significantly reduce the risk of transmitting HIV through breastfeeding. Thus, in 2010 World Health Organization (WHO) issued the latest guidelines on HIV and infant feeding entitled Principles and recommendations for infant feeding in the context of HIV and a summary of evidence. The 2010 WHO guidelines have changed the recommendations on how HIV infected mothers should feed their infants, and how health workers should support them. National authorities in each country can decide which infant feeding practice will be primarily promoted and supported by Maternal and Child Health services, i.e. breastfeeding with an antiretroviral intervention to reduce transmission or avoidance of all breastfeeding. Previous guidelines and recommendations on infant feeding in the context of HIV have undergone frequent changes over the past decade. The adaptation and implementation of previous and current guidelines at national level have met challenges. These include lack of consensus among key stakeholders, inadequate funding for the additional cost of providing ARVs to the mother or the child and difficulties in communicating the recommendations in the new guidelines clearly to mothers, health workers and policy makers. To address these challenges a number of proposals have been suggested such as coordinated consensus building process, costing of interventions and a phased implementation approach to ensure successful scale up over time. This paper describes the process of adapting global HIV and infant feeding recommendations and guidelines at national level. It also reviews the challenges encountered in implementation and proposes the way forward in addressing them.

Varieties of legumes are recognized as an important source of protein and dietary minerals by a number of ethnic groups in East, South and Central Africa. Among the legume that is preferred b y most Africans are the bean varieties . Beans are consumed in many forms: the young leaves, green pods, and fresh bean grains are used as vegetables; dry bean grains are used in various food preparations, and both are used as relish or side dishes together with the staple food. Apart from alleviating food insecurity, the bean leaves , green bean pods and fresh bean grains are good sources of micronutrients especially iron and zinc . Thirty eight varieties of beans deemed to be rich in minerals iron and zinc collected from a n umber of locations in East and Central Africa were brought from University of Nairobi and multiplied at Sokoine University of Agriculture, Morogoro. Bean leaves and fresh beans grains were picked for analysis after the plants reached three weeks and two months, respectively. Iron and zinc content was determined by atomic absorption spectrophotometer after ashing the samples. Analysis showed that leaves had significantly (P<0.05) more iron than the fresh bean grains. For bean leaves, Maharagi soja had the highest level of iron (1653.9 mg/100g) followed by Nain De Kiondo (1061.1 mg/100g). Similarly, Maharagi soja had the highest level of zinc (40.8 mg/100g), followed by Kiangara (40.5 mg/100g). Variety HRS 545 fresh bean grains , had the highest level of iron(1114.0 mg/100g) followed by Ituri Matata (983.4 g/100g) while highest zinc content was found in HRS 545 (41.1 mg/100g) followed by RWR 10 (41.1 mg/100g). These levels of minerals are significantly higher than the average amount found in dry bean grains (Fe 5.6 – 8.0 mg/100g) and (Zn 1.7 - 2.0 mg/100g). Creating more awareness and encouraging the utilization of bean leaves and fresh bean grains will contribute in alleviating micronutrient deficiencies especially among the vulnerable groups such as children, pregnant and lactating women, and resource-poor families.

Authors:   Addis Ababa University, Ashagrie Z , Abate D
Published: November 2021

Mould spoilage is a serious problem that affect s the shelf life of injera , the staple Ethiopian fermented bread. Injera is made from teff ( Eragrostis tef ) but other cereals may also be used in combination with teff. About two- third of Ethiopian diet consists of injera and it accounts for about two -third s of the daily protein intake of the Ethiopian population. I njera has a high nutritional value, as it is rich in calcium and iron. Unfortunately, injera has a shelf life of only 3-4 days essentially due to mould spoilage. The use of weak organic acid as preservative is allowed in acidic foods, primarily as mould inhibitor s. In this study, the effect of chemical preservatives such as benzoic acid, sodium benzoate, potassium sorbate and calcium propionate were investigated to prolong shelf life of injera . The preservatives were added immediately before baking at the concentration of 0.1% of benzoic acid, 0.1% sodium benzoate, 0.2% of potassium sorbate, 0.3% of calcium propionate and 0.2% blend of the four as recommended by Food and Drug Administration of USA. Three fungal species: Aspergillus niger , Penicillium sp and Rhizopus sp were found to be responsible for injera spoilage. Penicillium and Rhizopus were more dominant at storage temperature of between 16- 20 0 C, while Aspergillus niger was found to be more dominant at higher temperature of 25 -32 0 C. Injera samples had a pH and moisture content between 3.38- 3.45 and 62- 65%, respectively. Anti -fungal activities of the preservatives investigated significantly prolonged the shelf life of injera for up to12 days. It was found out that the effectiveness of preservation was ranked as sodium benzoate>benzoic acid>potassium sorbate>blend>calcium propionate showing that benzoate and benzoic acid are the most effective. The outcome of the research has a significant implication in food security, energy utilization and a significant reduction in the amount of time used by women to produce injera

Published: November 2021

The paper considers selected features of the protective ion-plasma coating deposition onto large-sized gas turbine components using vacuum-arc method by means of the MESh-50 and MAP-R pilot plants. The units have been developed based on the long-term operating experience of MAP-1 (MAP-1M) serial production. These plants are widely used in Russian and international aircraft-building complexes enabling all basic ion-plasma technological processes using standard cathodes made of nickel, cobalt, aluminum alloys and pure metals (Cu, Ti, Cr, Zr, etc.). The increased dimensions of the deposition chamber and the simultaneous use of several evaporators with pipe cathodes 180 mm in diameter and 540 mm high make it possible to apply coatings to large-sized components of gas turbine engines and plants, including such complex parts as “blisk” and “blink”.

A carência dos serviços efetivos de gestão de resíduos sólidos urbanos (RSU) tem provocado impactos negativos nos recursos naturais e nas condições de vida das populações. Ao investigar os impactos ambientais que os RSU ocasionam e a precariedade da disposição atual desses resíduos em diversos municípios, observa-se a necessidade de buscar novas e suficientes alternativas, para aperfeiçoar a gestão e eficiência e reduzir custos, melhorando a proteção ambiental. O estudo objetivou compreender como se organiza a coleta de resíduos sólidos, de forma geral, no mundo e no Brasil, com um recorte para o município de Bonito-Brasil, com a finalidade de elaborar um diagnóstico local, comparando-o com dados nacionais e internacionais. A metodologia consistiu em duas etapas: i) revisão bibliográfica com as principais informações sobre a gestão dos resíduos sólidos, em que os autores fizeram uma reflexão sobre os modelos de gestão dos resíduos considerados eficazes; ii)aplicação de questionários no ambiente de ferramentas do Google e o software IRaMuTeQ (acrônimo de Interface de R para Análise Multidimensional de Textos e Questionários). Os questionários foram aplicados no município de Bonito, para a caracterização local. Os resultados mostraram que a maioria das pessoas (72%) destina os resíduos para os pontos de coleta pública comum e 26% para a coleta seletiva, sendo que a maior parte (53%) dos voluntários realiza a separação correta dos resíduos. As análises mostram que, apesar de avanços desejáveis, ainda há necessidade de conscientização, informação e divulgação dos programas e iniciativas implantados pela prefeitura, no que se refere às diretrizes, princípios, instrumentos, práticas e modalidades de coleta adotadas. A partir das análises, constatou-se a intenção de praticar o gerenciamento dos resíduos sólidos, por parte dos voluntários.

In the context of university quality insurance, student satisfaction became one of the main indicators of service success given by the institution. Measurement of student satisfaction became an invaluable input for the institution to determine the direction of urgent improvement. This study aimed to describe student satisfaction with academic services and analyzed the quality of academic services to produce measurable improvement suggestions. This research involved students in the Department of Mathematics and Natural Sciences Education, Faculty of Education and Teacher Training, Mulawarman University, as the respondents, which are 165 students, representing 6 study programs selected by Stratified Random Sampling technique with the stratum length of study, which fill the online questionnaire. The instrument used is an adaptation of the Student Satisfaction Survey (SSI). The analysis results showed that the academic services in Faculty of Teacher Training and Education Mulawarman University still need to be improved because 50.9% of respondents stated satisfied, but 49.1% stated not satisfied. The level of student satisfaction by gender tends to be the same, i.e. 2.51 for male students and 2.53 for women, while based on study period and GPA tends to increase with the duration of the study period and the increasing GPA. According to Importance-Satisfaction Matrix, the quality of academic services put all dimensions in the second quadrant, which means that the dimensions of satisfaction had been quite good.Keywords: Academic Service; Quality; Student Satisfaction; University

Abstract. The spread of Covid-19 in Indonesian territory is increasing. In preventing covid-19 transmission in the campus environment, learning methods in universities in all zones must be implemented the e-learning for theoretical and practical subjects. However, when it comes to graduation and student competencies that cannot be implemented in e-learning, these activities can be held while maintaining the health and safety of students and lecturers. On the other hand, not all students and lecturers are accustomed to doing e-learning. Therefore, problems will arise about how e-learning management can improve student learning independence in the Economic Education Study Program of Ronggolawe University. This research was descriptive using the survey method. The research subjects were the head of the study program, lecturers, students and support technicians data collection techniques through questionnaires and documentation of e-learning implementation reports. The research data analysis was carried out descriptively by calculating the percentage and through the average score, interval, and categorization. Based on the data analysis, it was obtained: 1) e-learning management was 3.49 (quite effective); 2) Students responded positively to online learning during the Covid-19 pandemic, 3) independent learning in e-learning shows that 7.69% of students have low learning independence, 21.61% are less independent, 40.07% are quite independent and 27.63% have high independence. It could be prepared that e-learning management was quite effective in increasing student learning independence. However, there were still some aspects that need to be improved. It can be concluded that the management of e-learning was quite effective in increasing student learning independence. However, there were still some aspects that needed to be improved. These aspects included: 1) Optimizing the planning and implementation of e-learning, 2) preparing a repository of digital materials that are easily accessible to students, 3) the readiness of students to participate in e-learning.Keywords: Management, E-Learning, Learning Independence

Plasmodium species that cause malaria, a disease responsible for about half a million deaths per annum despite concerted efforts to combat it. The causative agent depends on type III beta phosphatidylinositol 4-kinase (PPI4K) during the development of merozoite. PPI4K is the only clinically validated Plasmodium kinase so far and its inhibitors are effective both in vitro and in vivo. In this work, a small library of ~22 000 fragments was virtually screened using PPI4K homology model to discover potential ligands of the enzyme. 16 virtual hits were selected based on ≤ -9.0 kcal/mol binding energy cut off and were subjected to similarity and substructure searching after they had passed PAINS screening. The derivatives obtained showed improved binding energies, which ranged from -10.00 to -13.80 kcal/mol. Moreover, the topmost ranking compound 31, with interesting drug-like quality was stable within the protein’s binding cavity during the 10 ns molecular dynamics simulation period. In addition, analysis of its binding pose revealed some unique binding interactions with PPI4K active site residues as the basis for the observed improved binding affinity. Overall, compound 31 appears to be a viable starting point for the development of PPI4K inhibitors with antimalarial activity.
A Brief Perspective on the Use of Bio-inoculants in Horticulture
Authors: Shankar Arpitha
Published: November 2021

Soil is a treasure trove of microbial variety, and bio-inoculants have the potential to improve the performance of horticultural crops under biotic and abiotic stress by boosting soil microbial diversity. Bio-inoculants are being developed to increase the diversity of soil microbes. The combined effects of bio-inoculants, on the other hand, result in the expansion of vegetation in the surrounding environment. Previous study on arbuscular mycorrhizal fungus has shown the existence of agronomic and biochemical characteristics in horticultural crop species (AMF). Through the development of enhanced technologies for the analysis of RNA or DNA from soil, we may acquire a deeper knowledge of the microbiological diversity and functions of the planet, which are difficult to find using traditional societal approaches. It is not possible to uncover a full database of purposeful genetics, which includes both soil microorganisms and deliberate genetics. This is true for almost every soil type or circumstance. As a result of this review, this study offers suggestions for the use of bio-inoculants, the benefits of doing so, regular research strategies, and long-term research directions.

The bloom-forming toxic dinoflagellate Alexandrium catenella was first detected in Southern Chile (39.5–55°S) 50 years ago and is responsible for most of the area’s cases of paralytic shellfish poisoning (PSP). Given the complex life history of A. catenella, which includes benthic sexual cysts, in this study we examined the potential link between latitude, toxicity, and sexual compatibility. Nine clones isolated from Chilean Patagonia were used in self- and out-crosses in all possible combinations (n=45). The effect of latitude on toxicity, reproductive success indexes, and cyst production was also determined. Although the toxin profiles were similar for all strains, consisting of C1, C2, GTX4, GTX1, GTX3, and NeoSTX, a latitudinal gradient was determined for their proportions (%) and content per cell (pg cell−1), with the more toxic strains occurring in the north (−40.6°S). Reproductive success also showed a latitudinal tendency and was lower in the north. None of the self-crosses yielded resting cysts. Rather, the production of resting cysts was highest in pairings of clones separated by distances of 1000–1650km. Our results contribute to a better understanding of PSP outbreaks in the region and demonstrate the importance of resting cysts in fueling new toxic events. They also provide additional evidence that the introduction of strains from neighboring regions is a cause for concern.

Self-Concept as Impulse Buying Controller in Homemakers

Abstract

This study aims to analyze the effect of self-concept on impulse buying at homemakers. The location conducted this research is Baros Village, Sukabumi City, West Java Province. This study involved 100 homemakers who were selected purposively. Data collection was carried out from April to June 2021 using the survey method. Data were analyzed using descriptive statistics and inferential statistics (simple linear regression test). The results showed that homemakers had self-concept and impulse buying in the medium category. Self-concept has a negative and significant effect on impulse buying. The results of this analysis indicate that a better self-concept can reduce impulse buying for homemakers. That is, the housewife's self-concept can control impulse buying at homemakers. Thus, the way to minimize impulse buying for homemakers is by increasing the self-concept of homemakers.

Transcatheter Embolization of Systemic-to-pulmonary Artery Fistulas: a Case Report
Authors: Zhang Shen , Qian Jun
Published: November 2021

The systemic artery to pulmonary vessel fistula(SAPVF) is an uncommon vascular abnormal communication between systemic arteries (except bronchial arteries) and the lung parenchyma[1]. It can be divided into congenital and acquired causes. Congenital SAPVF is often accompanied by cardiac or pulmonary artery hypoplasia, and acquired are usually caused by pleural adhesions after pleurisy, empyema, trauma, or surgery[2].We report a case of transcatheter arterial embolization for the treatment of congenital right inferior phrenic artery to pulmonary artery fistula.
