Authors: Karande S , Gogtay NJ , Shaikh N , Sholapurwala R , More T , Meshram P 
Published: March 2023

Background and Objectives:
Students with borderline intellectual functioning (“slow learners”) underperform in all school subjects. The primary objective of this study was to evaluate the self-perceived anxiety symptoms of slow learners. Its secondary objective was to analyze impact of sociodemographic variables on their symptoms.

Settings and Design:
Cross-sectional single-arm questionnaire-based study was conducted in the learning disability clinic of a public medical college in Mumbai.

Subjects and Methods:
One hundred slow learners aged ≥8 to <18 years were recruited by non-probability sampling. Their anxiety symptoms scores were measured using the Screen for Child Anxiety Related Disorders-Child version (SCARED-C) instrument.

Statistical Analysis:
Multivariate regression analysis was performed for determining the “independent” impact that variables had on the SCARED-C (“individual subscales” and “overall”) scores.

Results:
Symptoms of “separation anxiety” were present in 40%, followed by “social anxiety” in 32%, “generalized anxiety” in 31%, “panic” in 26%, “significant school avoidance” in 24%; and “overall anxiety” in 38% of slow learners. Multivariate analysis revealed that: (i) co-occurring attention-deficit/hyperactivity disorder was significantly associated with having panic symptoms (P = 0.040), and, (ii) studying in a Secondary School Certificate or Higher Secondary Certificate educational board-affiliated school was significantly associated with having symptoms of “generalized anxiety,” “social anxiety,” and “overall anxiety” (P = 0.009, P = 0.026, and P = 0.046, respectively).

Conclusions:
Many slow learners in our city have symptoms of anxiety disorders and overall anxiety. There is an urgent need to screen them for anxiety disorders to facilitate their optimum rehabilitation.

This paper explores the use of nanofiltration (NF) and Reverse Osmosis (RO) to remove the pharmaceutical Fluoxetine (FLX) from water. This substance can be found in rivers and lakes and requires studies involving the application of efficient technologies for its removal or mitigation. The study evaluated NF and RO membranes as an alternative to remove Fluoxetine from water. NF removed fluoxetine within the range between 50 and 60%, and RO demonstrated higher efficiency in removing the drug (98.8%). RO is a suitable method as a complementary treatment of water to ensure a lower concentration of FLX in water.

Authors: Akpo Ibidon F. , Dohou Modeste D. , Kakpo Salim O. 
Published: March 2023

Au Bénin, l’oignon est un légume qui est majoritairement inclus dans le régime alimentaire de la population. Son importance sans cesse croissante amène les producteurs à faire usage à outrance des pesticides chimiques dans le but d’avoir plus de gain. La présente étude s’est intéressée donc à l’analyse de la durabilité agricole des exploitations d’oignon dans les plus grandes zones de production d’oignon que sont les communes de Malanville et de Karimama. Sur la base d’un échantillon aléatoire de 120 producteurs, constitués suivant une approche participative basée sur des indicateurs (PIB), la durabilité agricole des exploitations d’oignon a été mesurée suivant trois dimensions : économique, environnementale et sociale. Les résultats ont révélé des valeurs de 71 pour la durabilité économique, de 59,56 pour la durabilité sociale et de 43,57 pour la durabilité environnementale. Ces valeurs montrent que la dimension environnementale impacte négativement la durabilité des exploitations car la valeur seuil de durabilité était de 50. La faiblesse de ce score de durabilité impose la nécessité de mettre en place des actions et réformes pour améliorer le niveau de durabilité général des exploitations d’oignon dans une dynamique d’agroécologie.
In Benin, onion is a vegetable that is mostly included in the population's diet. Its increasing importance leads producers to make excessive use of chemical pesticides in the aim of obtaining more profit. The present study therefore focused on the analysis of the agricultural sustainability of onion farms in the largest onion production areas, namely the municipalities of Malanville and Karimama. Based on a random sample of 120 producers, constituted following a participatory approach based on indicators, the agricultural sustainability of onion farms was measured along three dimensions: economic, environmental and social. The results revealed values of 71 for economic sustainability, 59.56 for social sustainability and 43.57 for environmental sustainability. These values show that the environmental dimension negatively impacts the sustainability of the farms, as the threshold value for sustainability was 50. The weakness of this sustainability score imposes the need to implement actions and reforms to improve the general level of sustainability of onion farms in an agroecological dynamic.

Published: March 2023

La contamination des sols par des éléments traces métalliques est l’un des problèmes environnementaux les plus pressants. La mise en décharge d’ordures ménagères est une source de cette contamination. La présente étude a pour objectif d’évaluer l’impact de la décharge urbaine de Mbeubeuss (Dakar) sur la contamination en Éléments traces Métalliques (ETM). La méthodologie consiste à prélever cinq (5) échantillons de sols retenus en fonction de leur proximité au point central de la décharge afin de caractériser les paramètres physico-chimiques (pH et conductivité électriques) et les teneurs en Éléments Traces Métalliques (ETM). Les valeurs des pH, comprises entre 6,5 et 8,1, montrent que les sols sont neutres ou légèrement alcalins avec des conductivités électriques élevées [0,98-0,11ms/cm]. Les résultats des analyses des teneurs en ETM par XRF montrent que les sols de la décharge de Mbeubeuss sont riches en Cu (16,97-216 ppm), Fe (4250-12500 ppm), Zn (45,04-279,88 ppm), Pb (ld-322,78 ppm), Mn (652,11-803,25 ppm), Cr (37,52 – 67,17 ppm) et Ti (515,4-3753 ppm). L’évaluation de la contamination a été faite en calculant les indices de pollution et de géo accumulation. Cette étude montre une diminution de la pollution au fur et à mesure que l’on s’éloigne du point central et une accumulation de Zn et Pb à proximité de la décharge.
Contamination of soils with trace metals is one of the most pressing environmental problems. The dumping of household waste is a source of this contamination. The objective of the present study is to evaluate the impact of the urban landfill of Mbeubeuss (Dakar) on the contamination of Trace Metal Elements (TME). The methodology consists of taking five (5) soil samples selected according to their proximity to the central point of the landfill in order to characterize the physico-chemical parameters (pH and electrical conductivity) and the levels of Trace Metal Elements (TME). The pH Values, between 6.5 and 8.1, show that the soils are neutral or slightly alkaline with high electrical conductivities [0.98-0.11ms/cm]. The results of XRF analyses of TME content show that the soils of the Mbeubeuss dump are rich in Cu (16.97-216 ppm), Fe (4250-12500 ppm), Zn (45.04-279.88 ppm), Pb (ld-322.78 ppm), Mn (652.11-803.25 ppm), Cr (37.52-67.17 ppm) and Ti (515.4-3753 ppm). The contamination assessment was done by calculating the pollution and geo accumulation indices. This study shows a decrease in pollution as one moves away from the central point and an accumulation of Zn and Pb near the landfill.

Authors: Halidou Moussa Arohalassi , Elhadji Gounga Mahamadou , Issa Ado Rayanatou 
Published: March 2023

L’arbre de Sclerocarya birrea ou Marula est une espèce forestière aux usages multiples très répandue en Afrique, mais peu étudiée au Niger. L’objectif général de cette étude est la caractérisation des fruits de l’espèce S. birrea afin de mieux contribuer à sa valorisation. Les échantillons ont été collectés au niveau de 7 sites de deux régions et analysés au laboratoire pour déterminer la composition biochimique selon les méthodes AOAC (1990). La caractérisation de la pulpe montre des teneurs moyennes en eau variant de 80,3 à 86%, celles en protéines, lipides et glucides sont respectivement de 3,12 ± 1,48%, 2,78 ± 0,74% et 86,30 ± 2,55% respectivement avec une valeur énergétique de 382,68 ± 7,56 Kcal. L’amande est composée en moyenne de 6,08 ± 1,74% d’eau et 3,96 ± 0,39% de matières minérales. Elle est cependant assez riche en protéines (35,2 ± 2,47%) avec un taux important de matières grasses (46 ± 5,97%), de glucides de 14,8 ± 6,50%. L’énergie moyenne calculée est de 614 ± 29,3 Kcal. Il n’y a pas de différence significative de la composition des fruits. S. birrea démontrent ainsi une grande potentialité qui nécessite une meilleure valorisation et une vulgarisation pour contribuer à la sécurité alimentaire et nutritionnelle.
The Sclerocarya birrea or Marula tree is a multipurpose forest species widespread in Africa, but little studied in Niger. The general objective of this study is the characterization of the fruits of the species S. birrea in order to better contribute to its valorization. The samples were collected at 7 sites in two regions and analyzed in the laboratory to determine the biochemical composition according to AOAC (1990) methods. The characterization of the pulp shows average water contents ranging from 80.3 to 86%, those of proteins, lipids and carbohydrates are respectively 3.12 ± 1.48%, 2.78 ± 0.74% and 86, 30 ± 2.55% respectively with an energy value of 382.68 ± 7.56 Kcal. The kernel is composed on average of 6.08 ± 1.74% water and 3.96 ± 0.39% mineral matter. It is however quite rich in protein (35.2 ± 2.47%) with a high rate of fat (46 ± 5.97%), carbohydrates of 14.8 ± 6.50%. The calculated average energy is 614 ± 29.3 Kcal. There is no significant difference in composition depending on the origin of the fruits. S. birrea thus demonstrate great potential that requires better development and popularization to contribute to food and nutritional security at the level households.

Authors: Ahmed H. , Adedoyin O.T. , Ojuawo A. , Zamo A.B. 
Published: March 2023

Background: Urinary tract infections (UTIs) remain a common cause of childhood morbidity, if poorly treated or undiagnosed, could result in long-term morbidities e.g. hypertension, failure to thrive and end-stage renal disease (ESRD). An appropriate antimicrobial susceptibility pattern is essential.
Objective: The study determined the profile and antibiotic sensitivity patterns of bacterial strains isolated from febrile under-five children in Azare, North-Eastern Nigeria.
Methods: 145 febrile under-five children seen in Federal Medical Centre Azare over six months(March to August 2008)were enrolled in a hospital-based prospective study. Urine obtained by midstream and suprapubic bladder aspiration was subjected to urinalysis, urine microscopy, culture and sensitivity.
Results: Of the 145 subjects enrolled, 34(23.4%) had UTI;24(70%) males and 10(30%) females .Gram-negative organisms accounted for 67.6%, Gram-positive organisms 32.4% of isolates; Escherichia coli in 12 (35.3%) cultures; Staphylococcus aureus; 11 (32.4%); Klebsiella species; 8 (23.5%).The gram- negative enteric bacilli had a high prevalence of resistance against ampicillin, amoxicillin, nalidixic acid, nitrofurantoin and co-trimoxazole.
Conclusion: Escherichia coli was the most prevalent bacterial organisms isolated. Others were Klebsiella, Proteus and Pseudomonas species with Staphyloccocus aureus the only Gram-positive. The most effective agents were ceftriaxone, ciprofloxacin and gentamicin. A higher prevalence of UTIs was found in boys.
Role of Motivation in Learning English Foreign Language on the Academic Achievements of Students in China
Authors: Yung Leo 
Published: March 2023

Purpose: The purpose of this study is to investigate the role of motivation in learning English foreign language on the academic achievements of students in China.
Methodology: The study adopted a desktop methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.
Findings: The findings revealed that there exists a contextual and methodological gap relating to the role of motivation in learning English foreign language on the academic achievements of students in China. Preliminary empirical review reveals that motivation is a component that is both very crucial and effective in the process of picking up a new language. Therefore, it is important for instructors and lecturers of languages to learn about, appreciate, and pay attention to the personalities of the pupils in their classes. In addition, they need to have an understanding of motivation, the significant value it holds, and the different forms it might take.
Unique Contribution to Theory, Practice and Policy: The Gardner’s Motivation theory, the Acculturation model and the Self Determination theory may be used to anchor future studies relating to the role of motivation in learning English foreign language. The study will be beneficial to EFL teachers and other relevant stakeholders in establishing policies and strategies to promote motivation in learning English foreign language.

Authors: Khomich V. S. , Parfenov V. V. , Savchenko S. V. 
Published: March 2023

The results of the analysis of the current state and dynamics of concentrations of heavy metals and oil products in the soils of Belarusian cities for the period from 1990–1995 to 2016–2021 are presented. It is based on the soil monitoring data in the cities of Belarus within the framework of the National Environmental Monitoring System in the Republic of Belarus and the results of a detailed soil-geochemical survey of the city of Minsk, carried out by the authors in 1990. The dynamics of the content of chemicals in the soils of cities was assessed by comparing the average
concentrations for individual cities over the period under review and with comparison of the concentrations of chemicals in soil samples taken at the same sampling sites in the city of Minsk over a nearly 30-year period. It has been established that for most cities there is a tendency to accumulate zinc and oil products in the soil cover. There is a decrease in the content of lead in the soil in 46 % of cities and an increase in its concentration in 19 % of cities are observed. Similar to lead dynamic is typical for copper content in urban soils. It is shown that the annual average increase in the content of zinc in the soils of Minsk is 0.57 mg/kg per year, while the annual average decrease in the content of lead is 0.22 mg/kg per year.

Authors: Sokolova Zhanna V. 
Published: March 2023

The results of scientific work for updating of the polythematic Information and Search Thesaurus on Agriculture and Foods (IST) developed in the Federal State Budgetary Scientific Institution «Central Scientific Agricultural Library» (FSNSI CSAL) are presented. The work is carried out to accurately represent the content of documents in the process of indexing, providing the unified data presentation, adequately describing subject domains and increasing the searching possibilities of the thesaurus. The
main functions of the IST, which is a complex terminological
system with different kinds of semantic relationships between its elements (lexical units (LU)), are considered. The role of the IST as a branch reference of scientific vocabulary is particularly noted. During the investigation the IST content has been essentially enriched with new lexis in the following subject domains: plant protection, zoology, microbiology, botany, forest husbandry, agronomy The result of the research work on updating is a new version of the IST containing 62682 LU. More than 27 600 LU are scientific (Latin) names of organisms (of which 1 782 are new). In total, nearly 2 700 LU have been corrected (added, changed,
deleted). More than 2 800 links between terms (hierarchic,
synonymic and associative) have been added. The updated
version of the thesaurus, which includes new terminology,
enables adequate description of the subject areas, accurate
disclosure of the content of a document during its scientific
processing. It is an effective tool for indexing and thematic
search. The creation and development of IST of the FSNSI CSAL is in line with the current level of thesaurus development. The scope of the IST, the development of its vocabulary items and the semantic relationships of the terms represented in it make it possible to describe the subject areas related to agriculture, the food industry and related disciplines quite comprehensively.
The essence and significance of informal education for library specialists
Authors: Reut Anna M. 
Published: March 2023

In the modern world, the unity of formal, nonformal and informal education affects the success of professional activities of library staff. Informal education plays a significant role in the society, as it includes all possible branches of knowledge and provides an opportunity for the full development of a person and a specialist. The essential characteristic of informal education is the individual cognitive activity of a person. The article actualizes the problem of implementing informal education in the context of continuing
education of library specialists. The pros and cons of informal
education are considered, the psychological features of informal education and methods of overcoming emerging psychological barriers in its implementation are described. Social media is one of the methods of obtaining informal education, which allows users to get the necessary information in an accessible, capacious and clear form. The Instagram profile «Library Journalism» is an example of the informal education of library specialists through social media. It is noted that such online assistants for library specialists contribute to the development of multi-level education, which leads to the creative self-realization of librarians, their professional, intellectual and cultural improvement. The results of the study can find practical application in the implementation of informal education using an online methodological resource both in relation to the training of students of the library specialty and in relation to improving the competence of library practitioners.
