Self-Reported Assessment of Sources and Quality of Drinking Water: A Case Study of Sapele Local Government Area, Delta State, Nigeria
Authors: Edeki P.E. , Isah E.C. , Mokogwu N.
Published: April 2023

Background: Water is a basic physiological requirement of the body with about 30–35 liters per capita per day required for each household, a situation  which is far-fetched in most developing countries such as Nigeria. The study aimed to ascertain the sources, availability and accessibility of drinking  water in Sapele Local Government Area of Delta State, Nigeria.

Methods: This was a descriptive cross-sectional study among 362 heads of household who were selected using a multi-stage sampling technique. A total  of 360 wells from sampled households were examined to ascertain their compliance with WHO standards for improved/protected well. Data analysis was  done using SPSS version 21.0 with statistical significance set at p < 0.05.

Results: The commonest source of drinking water during dry and wet seasons was sachet water, 99 (27.3%) and 89 (24.6%), respectively. Two hundred  and ten (58%) respondents reported that their drinking water sources were located within 200 meters of their dwelling; 293 (82.3%) respondents had  access to water supply all the time, while 25 (7%) had access to water supply twice a week. Majority, 354 (97.8%) of respondents reported that their water  was colourless, 350 (96.7%), odourless and 208 (57.5%), tasteless. Only 21 (5.8%) of the wells examined met the WHO criteria for improved/protected well. 

Conclusion: Sachet water is the commonest source of drinking water and most wells examined did not meet the requirement of an improved well. The  Ministry of Water Resources should make more improved sources of water available for the residents of Sapele.

BackgroundAwareness of stroke is important for appropriate and timely stroke prevention and management.ObjectiveTo assess the level of awareness about the risk factors, signs, and appropriate responses for stroke among university employees in Rwanda.MethodsWe employed a quantitative descriptive cross-sectional approach. We involved 92 participants, and a self-administered questionnaire to collect data. We computed descriptive statistics and used the Chi-Square test to assess any differences in stroke awareness.ResultsWe found that 12% and 15.2% of the participants were not aware of any risk factor and warning sign of stroke respectively. Regarding the reaction in case a warning sign of stroke was noticed, 9.8% of the participants indicated that they would do nothing or advise the victim to take rest at home. The limited awareness was significantly higher in the administrative than academic employees for both risk factors (p=0.002) and warning signs (p=0.006), but not for the appropriate responses to stroke (p=0.426).ConclusionA significant proportion of the participants were not aware of any stroke risk factor, warning sign and appropriate responses. It is important to conduct further similar studies and implement stroke education interventions in university communities.Rwanda J Med Health Sci 2023;6(1):9-16

Ars Congressus Cum Daemone: Aleister Crowley and the Knowledge and Conversation with the Holy Guardian Angel
Authors: Bogdan Henrik
Published: April 2023

This article analyses experiential knowledge in the writings of the British occultist Aleister Crowley’s (1875-1947) writings, and more specifically the so-called Knowledge and Conversation of the Holy Guardian Angel. I will first discuss Crowley’s own account of his attainment of communion with his Guardian Angel, which he set out to accomplish in 1900 and finally realised in 1906. Second, I will discuss a few key texts written by Crowley in which the method for attaining the Knowledge and Conversation of the Holy Guardian Angel is described, with a special focus on Liber Samekh (1920). The first part of this article can thus be seen as the practiced aspect of the Holy Guardian Angel experience, while the second part is the *prescribed* aspect. By way of concluding, I will address the entangled nature of the instructional texts of the Knowledge and Conversation of the Holy Guardian Angel.
The Entanglement of Philosophy, Politics and the Occult: The Hidden Secret of early Post-Avicennan Thought in the Islamic East
Authors: Noble Michael
Published: April 2023

By the thirteenth century, philosophy, politics and occult science had become deeply entangled in the Persianate Islamic world. Two of the greatest luminaries in this intellectual milieu were Fakhr al-Dīn al-Rāzī (d.1210) and Shihāb al-Dīn Yaḥyā Ibn Ḥabash Ibn Amīrak al-Suhrawardī (d.1191/2), who at one point were fellow students of philosophy under a certain Majd al-Dīn al-Jīlī in Marāgha in northeastern Iran. Both subsequently sought royal patronage, the former travelling eastwards to Transoxania to secure the generosity of the Khwārazm-Shāhs, the latter travelling eastwards to the Levant to gain the intimate trust of Malik al-Ẓāhir, the son of the Ayyūbid sultan Ṣalāḥ al-Dīn—known in the West as Saladdin. Both composed works devoted to talismanic astral ritual. And crucially, both developed philosophical soteriologies coloured by their meditations on the “craft”—soteriologies with profound implications for the nature of political authority.
Print Grimoires and the Democratization of Learned Magic in the Later Early Modern Period: Bricolage Tradition and the Cross-Cultural Transmission of Knowledge
Authors: Davies Owen
Published: April 2023

The relationship between print and manuscript in the entanglement of ‘western learned magic’ provides valuable insights regarding the complexity of cultural transmission across societies and social strata. Through exploring the influence over time of two print books containing conjurations, one in English the other French, we can trace how seemingly tenuous relationships reveal unlikely global frames of reference with regard to learned magic.

Authors: Moço Carlos Eduardo Guimarães , Dias Luciana Fonseca , Volpasso Marcelle Cabral , Barbosa Márcio Luiz Borges , Pires Valéria Nascimento Lebeis
Published: April 2023

Introdução: Com as medidas emergenciais para tentar conter a disseminação do novo coronavírus, comportamentos e hábitos da população foram impactados e modificados. Por conta disso o comportamento sedentário e o tempo de tela aumentaram, somada a questão das atividades ao ar livre reduzidas. O objetivo da revisão é analisar os estudos científicos relacionados ao comportamento sedentário de universitários durante a pandemia da COVID-19. Metodologia: Trata-se de uma revisão integrativa nos anos de 2020 e 2021. A busca ocorreu nos acervos Web of Science, Scielo, PubMed e Biblioteca Virtual em Saúde (BVS – MEDLINE), utilizando os descritores “Sedentary behavior”, “COVID-19”, “Physical activity” e “Students”, com o operador booleano AND. Resultados: Foram selecionados 21 artigos. Foi possível perceber que os estudantes reduziram o volume total de atividade física (AF) e passaram a ter aumento no tempo sentado. Esses comportamentos contribuíram para uma vida mais sedentária, estando associados ao maior tempo de tela para atividades de lazer e estudos. O isolamento social foi uma das razões para isso, pois os estudantes passaram menos tempo visitando locais e mais tempo em casa. Conclusão: Pode-se perceber que os estudantes tiveram seu estilo de vida afetado, com um maior tempo de tela e um comportamento sedentário ocasionando um aumento de sintomas de estresse, ansiedade e depressão, comportamento alimentar inadequado e baixo nível de AF.

Published: April 2023

The growing demand of people who seek judo in today's society seems to exert influence so that traditional beliefs, values, habits and behaviors are changed towards modernity. Checking the perception of judo teachers about the teaching of fighting can contribute to a better understanding of this phenomenon. The objectives of this study were to identify the demographic, social and educational profile of judo teachers and to verify the perception of judo teachers about the teaching of fighting in gyms. Answered the semi-structured virtual questionnaire 233 judo teachers (M = 201; F = 32) who voluntarily participated in the study. 66.1% of those surveyed are graduates or are graduating in physical education and dedicate between 8 and 10 hours a week to judo. Educating the citizen (55.4%) and overall training of students (31.3%) were cited as the main objectives in teaching judo. Educational/philosophical aspects (60.9%) were identified as the most important in teaching, in an inverse relationship with competitive aspects (68.2%), considered less important aspects. The results indicate even though it is modernized, the practice of judo must keep non-modern values ​​and elements that are proper for human formation and life in society.

Published: April 2023

Imagem corporal e motivação são construtos frequentemente associados no contexto da prática dos exercícios físicos, considerando um número significativo de pessoas que buscam as academias de ginástica para a definição de formas corporais desejáveis a si próprias e aos outros. Este estudo teve por objetivo avaliar a associação entre imagem corporal e motivação para a prática de exercícios físicos em academias de ginástica, em respostas comportamentais de praticantes. Os participantes foram 301 pessoas (156 mulheres e 145 homens), com idade entre 18 e 71 anos, que praticam exercícios físicos em academias de Porto Velho-RO. Para a coleta de dados, adotou-se a Physical Activity and Leisure Motivation Scale (PALMS). A fundamentação se pautou na Teoria da Autodeterminação (TAD) e aplicou-se a análise fatorial confirmatória para a validação dos itens. Os resultados apontaram 8 itens da escala assumida relativos à imagem corporal, sendo que o item 21, "Porque as pessoas me dizem que preciso", não se confirmou, apresentando diferenças significativas em relação à proposta inicial da teoria, sugerindo a necessidade de se estudar a motivação e a imagem corporal como fatores diferentes. Conclui-se que a imagem corporal é um construto comportamental vinculado, predominantemente, à motivação extrínseca, mas ambas são influenciadas internamente, cujas variáveis devem ser analisadas tanto de forma simétrica como recíproca. Faz-se necessária a apropriação dos fundamentos da Psicologia por profissionais da área de Educação Física para a ampliação das intervenções que ajudem os praticantes de exercícios físicos à internalização de comportamentos autodeterminados, elucidando percepções em relação à sua imagem corporal.

Published: April 2023

A Organização Mundial da Saúde recomenda às pessoas com mais de cinco anos, uma quantidade mínima de atividade física semanal para obter efeitos substanciais à saúde. No Brasil, o ciclismo, com as suas diferentes finalidades, é a quarta modalidade de atividade física mais praticada por adultos, atrás da caminhada, musculação/ginástica e futebol. O ciclismo foi a modalidade que apresentou, na última década, a maior taxa crescente de novos praticantes. Enquanto se observa o aumento do protagonismo do ciclismo nos processos de mobilidade urbana, não se nota incremento do diálogo amplo e claro com as populações, para potencializar o uso de bicicletas como ferramenta segura, eficiente e confortável de promoção da atividade física e de saúde. Nesse sentido, esse ensaio acadêmico propõe apresentar a utilidade de algumas ações que interferem na decisão das pessoas usarem ou não a bicicleta, seja como meio de mobilidade, de lazer ou de transporte. Pretende-se com esta temática, alavancar ações de planejadores da mobilidade urbana na direção do desenvolvimento de programas que oportunizem as pessoas usarem bicicletas, para serem mais ativas fisicamente e alcançarem qualidade de vida.

Published: April 2023

Tobacco leaves have active compounds such as phenols and alkaloids that can be used as antibacterial and antiseptic because they can damage the cell components of microorganisms. Tobacco leaf extract in hand sanitizer gel has been shown to have antibacterial activity against Staphylococcus aureus and Eschericia coli bacteria at a minimum concentration of 0.25%. Hand sanitizer is an antiseptic product that is used to clean hands and is preferred because it is practical, has a cooling and dries quickly when compared to hand soap. To make hand sanitizer products that are safe for the skin, various chemical compounds are used as building blocks, including CMC-Na and glycerin. CMC-Na acts as a gelling agent and glycerin has a role as a vehicle. This study aims to obtain the optimum formula for hand sanitizer gel preparations with variations in the concentration ratio of CMC-Na and glycerin using Simplex Lattice Design (SLD) and to determine the effect of variations in the concentration ratio of CMC-Na and glycerin on physical, chemical, and microbiological characteristics of the results of the optimum formula for hand sanitizer gel preparations. The research method used in this study is a type of laboratory experiment using Completely Randomized Design (CRD). The data obtained from the research results were processed using Analysis of Variance (ANOVA) with a 95% confidence level and continued with Duncan's Multiple Range Test at a significance level of 5%. The results showed that there were 3 optimum formulas for hand sanitizer gel of tobacco leaf extract based on the desirability value, 0.912 (Formula 1), 0.457 (Formula 4) and 0.653 (Formula 5). The variation of the concentration ratio of CMC-Na and glycerin in the optimum formula showed that CMC-Na had the most dominant influence on physical (homogeneity), chemical (total flavonoid) and microbiological (antibacterial and antiseptic) characteristics. Meanwhile, glycerin has the most dominant influence on product viscosity stability. The three optimum formulas have homogeneous gel characteristics.

Published: April 2023

Irrigation water is one of the major limiting factors that affect crop production in Ethiopia. Irrigation scheduling is an important technique for quantifying water required by plants at a particular interval to improve irrigation efficiency. The objective of this study was to evaluate the irrigation scheduling effects on potato yield and water productivity. The study was designed in four experimental treatments as: 5, 7, 9 days intervals, and Farmer practice arranged in randomized complete block design with three replications. The two years combined yield results showed that a maximum yield of 21.99ton/ha was obtained from 9 days irrigation interval treatment and a minimum yield of 15.80ton/ha was obtained from Farmer’s practice. Maximum and minimum water productivity of  3.34 kg/m3 and 2.4 kg/m3 were obtained from 9-day irrigation intervals and farmers’ practice, respectively. From these results, it can be observed that to attain the maximum potato yield and water productivity in the study area, it is better to use 9-days irrigation interval with a determined irrigation water amount.

Authors: Janarny Ganesamoorthy , Ranaweera Somathilaka , Gunathilake Prasanna Priyantha
Published: April 2023

Cassia fistula is a well-known plant species for the medicinal use of it leaves, barks and flowers. It has been identified as a rich source of phenolics which can be attributed to its medicinal properties. However, these phenolics should be extracted appropriately to effectively utilize them in various applications. This study focused on maximizing the extraction yield of total phenolics and total anthocyanins along with maximum 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity from edible flowers of C.fistula as a function of solid:liquid ratio, ethanol concentration, extraction temperature and time. The data was subjected to response surface methodology and the corresponding second order polynomial models were generated. The results showed that the polynomial models for all responses were significant, did not show lack of fit and presented determination of coefficients above 95%. This indicates the suitability of the models for prediction purposes. Using desirability function, the optimum extraction process parameters to obtain maximum values of all responses was found to be 29.56% ethanol, 1:45 solid to liquid ratio at extraction temperature of 31°C and time 24 minutes. Under these optimal conditions, the experimental values were in close agreement with the predicted values and did not show any significant difference (p<0.05). The identified optimized conditions could be used to extracts phenolics from C.fistula flowers in a cost effective and efficient manner.

Authors: Savchuk E.S. , Sokolenko V.I. , Karaseva E.V. , Mats A.V. , Frolov V.A. , Pylypenko M.M.
Published: April 2023

The regularities of creep, mechanical characteristics, and structure evolution of Zr1Nb nanocrystalline alloy obtained by intensive plastic deformation and hydrogenated from a gaseous medium are studied. It is shown that, due to deformation under creep conditions, a small amount of zirconium hydrides is formed in the structure of the Zr1Nb alloy, which has little effect on its strength properties and ductility. The observed features of the creep
characteristics are mainly due to the past relaxation of internal stresses and the corresponding structural transformations during hydrogenation and subsequent deformation.

Authors: Reshetnyak E.N. , Luchaninov A.A. , Strel’nitskij V.E.
Published: April 2023

Diamond-like carbon (DLC) coatings are used to improve the quality of industrial products due to a wide range of exceptional physical, mechanical and tribological properties. Problems that limit the scope of application of hard non-hydrogenated DLC coatings with properties closest to those of diamond are considered. The scientific literature is reviewed devoted to improving the characteristics of DLC-based wear-resistant coatings. The approaches currently used to reduce internal compressive stresses, improve adhesion to the substrate, and increase the strength of coatings are analyzed. Aspects of optimization of deposition parameters, doping, constructing the gradient and multilayer structure are considered. Based on the generalization of the results of the reviewed publications, a
conclusion is made about the advantages of using coatings with a multilayer structure. A promising design undoped multilayer DLC coatings with high protective properties is discussed.
RESEARCH OF SPECIAL LIMITS DURING HEAT TREATMENT OF MATERIALS IN THE TWO-PHASE REGION UNDER SUPERCRITICAL TEMPERATURE INFLUENCE
Authors: Sereda Borys , Kryhliyak Irina , Sereda Dmytro , Voloh Vitaliy
Published: April 2023

The results of the research on establishing the dependence of the coercive force (Нs) on special boundaries in a low-carbon alloy are given. Annealing at a temperature of 900 ºС with a holding time of 1 to 3 h leads to an increase in the number of special boundaries from 22.7 to 37.17% and to an increase in magnetic permeability and, accordingly, a decrease in the coercive force from 1.60 to 1.24 A/cm. When the load is axially stretched, the coercive force changes. The initial stage of plastic deformation is most sensitive to the growth of coercive force, which allows us to identify areas in which local plastic deformation has occurred, which indicates a significant decrease in the operational characteristics of parts.

Differences in Melanoma Survival in Hispanic Subpopulations
Authors: Ramachandran Vignesh
Published: April 2023

Melanoma can be deadly if not detected and treated early. The association of race with survival in cutaneous malignancies has been researched previously and it has been noted that Hispanic patients have worse melanoma-specific survival compared to non-Hispanic white patients [1]. While research has shown that Hispanic race can be a factor in melanoma survival rates, the specific impact of Hispanic subpopulations on melanoma outcomes is not well understood. In recent years, the Hispanic population in the United States has grown rapidly and is expected to continue to do so in the coming decades. These populations represent diverse individuals from various countries of origins, ethnic backgrounds, and differing cultures. In fact, the Hispanic nomenclature includes diverse worldwide subpopulations and clinical investigations often focus on the ethnic group, resulting in an incomplete characterization of skin malignancies and survival among distinct Latino groups. It is important to understand the unique melanoma survival patterns among different Hispanic subpopulations as these populations are heterogenous.

El aumento de las plantaciones con fines comerciales de Guazuma crinita, una especie prominente en la Amazonia peruana, requiere que se mejoren las mediciones de los árboles para la cuantificación del volumen de madera. Esta investigación tuvo como objetivo determinar el error en la medición del diámetro normal del fuste (dap) y en el cálculo del volumen, cuando el diámetro normal del fuste se mide con cinta métrica, cinta diamétrica y forcípula de aluminio. Se midieron 41 árboles de una plantación forestal de Guazuma crinita, de 13 años, en la zona de Pucallpa, Amazonia peruana. Con la forcípula se midieron dos diámetros y los promedios se obtuvieron con la media aritmética y la media geométrica. La irregularidad de la sección transversal de los fustes de los árboles fue cercana a uno. El análisis descriptivo e inferencial encontró que la medición de un dap, con una forcípula, se diferencia notablemente de los otros métodos y genera el mayor error relativo, con 4 % para el diámetro normal y 7.9 % para el volumen, a nivel de árbol. Pero, a nivel de hectárea, se encontró un error absoluto de hasta 7.7 m3/ha, cifra importante desde la dimensión industrial y financiera. Se concluyó que el diámetro normal se puede medir, indiferentemente, con una cinta métrica, cinta diamétrica o mediante la media de dos diámetros con una forcípula de aluminio. Además, se concluyó que es indistinto usar la media aritmética o la media geométrica.

Este artículo presenta las percepciones de los habitantes del distrito de Pampas Tayacaja sobre la contaminación del agua del río Opamayo, sus efectos y su origen. Cabe señalar que este afluente a lo largo de su recorrido es contaminado por efectos de la agricultura, ganadería y desagües municipales, entre otros. Una percepción común es que la calidad del agua del río Opamayo varía de buena a muy mala. La mayoría de las personas entrevistadas dijeron que el agua del río no es limpia porque no hay un debido tratamiento y que en época de estiaje el rio presenta agua clara con pequeñas piedras, y esto indica de manera visual que el agua se encuentra en el estado mesotrófico. La principal fuente de contaminación del río Opamayo ha sido identificada como la descarga de aguas residuales al río y arrojo de basuras. Los encuestados esperan que el saneamiento del río Opamayo tengan beneficios, especialmente para sus descendientes, quienes podrían disfrutar del río con agua limpia para uso agrícola. Sin embargo, se muestran escépticos sobre el papel de instituciones gubernamentales en la solución del problema

Conocer el valor económico maderable en pie, es un elemento importante para alcanzar un manejo eficiente y perseguir el desarrollo sostenible, poniendo énfasis en el bienestar social. Por tal motivo, en la investigación se evaluaron cuatro plantaciones de Eucalyptus globulus Labill, distribuidos en cuatro anexos del distrito Daniel Hernández, perteneciente a la provincia Pampas Tayacaja. Se inventarió en total 77 individuos en cuatro fajas instaladas (una faja por plantación) de 50 m de longitud y 2 m de ancho. Se evaluaron variables cuantitativas (altura y diámetro de los árboles) y variables cualitativas (calidad de fuste y edad de los árboles) con la finalidad de obtener el valor económico maderable de las cuatro fajas. Como resultados se reportó que el 18,2 % de los árboles registran más de 40 cm de diámetro y se encuentran en situación de aprovechables; sin embargo, el 79,2 % presentan calidad de fuste 2 y 3, lo que implica que se debería realizar o aplicar tratamientos silviculturales. Asimismo, el valor económico maderable total de las cuatro fajas (considerando calidad de fuste y edad) fue S/. 7 473,18.

Youth and digitalization have an essential role in the nation's development Youth as an agent of change, which brings new ideas and innovation. In contrast, digitalization brings changes in terms of efficiency and effectiveness which are able to become a source of new economic growth. The existence of COVID-19 pandemic has caused barriers for youth to enter the workforce since graduate school (school-to-work transition), which is a blessing in disguise as technology adoption accelerates and creates new job opportunities for youth as it requires digital skills. Youth which are considered as adaptive to technology by nature, are considered to have the opportunity to increase their work participation through transitioning jobs to the digital sector. This study aims to analyze the influence of human capital in the form of education and training in fresh graduates' youth on opportunities to transition jobs to the digital sector. The data source and method used resulted from the August 2021 National Labor Force Survey (Sakernas) and multinomial logistic regression. The study result shows that education and training influence youth's transition to the digital sector. Young fresh graduates with higher education have a 1.491. times higher tendency to make the transition to the digital sector. Participation in training for youth will also increase the tendency of 1,525 times for youth with secondary education and 1,239 times for youth with higher education to transition to the digital sector. Pre-Employment Program (Prakerja) participation will also increase the tendency by 1,314 times to transition to the digital sector. Other findings show that higher educational attainment and training participation will reduce the tendency for young fresh graduates to transition to the non-digital sector and choose to be unemployed, which indicates that it is consistent with work decision theory that the higher the investment in education and training, the higher the reservation wage will also be.
