Authors:   Department of Physics,, Osmania University, Hyderabad, 500007, India, Reddy T Devender , Padmasree G , Reddy P Yadagiri , Reddy Ch Gopal
Published: September 2024

Objectives: Investigations on structural, morphological and electrical studies of Pr substituted YFeO3 samples synthesized through sol-gel route are presented in this paper. Methods: PrxY1-xFeO3 (x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) samples are synthesized by sol-gel auto combustion method. Structural characterization of the samples is done by using X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM) and Energy dispersive X-ray (EDX) techniques. Electrical properties are studied by J-E and Ln J-Ln E measurements. Findings: Rietveld refined XRD structural analysis shows sharp intense peaks indicating the crystalline nature of the samples and all the samples possess distorted orthorhombic structure with space group Pbnm. FESEM analysis shows non-uniform nature of grain size with increasing porosity. EDX data confirms elemental composition, weight and atomic percentage of the prepared samples which further confirms their purity. The leakage current density increases with increase in Pr doping. The slopes of Ln J-Ln E graphs of all the samples are in the range of 1.11 to 1.51 confirming that Ohmic conduction is predominant conduction mechanism. Novelty: Investigations on the effect of Pr substitution on electrical properties of single phase YFeO3­ samples reveal that the substitution of Pr in YFeO3 decreases the ferroelectric nature of the samples. Keywords: Sol-gel method, XRD, FESEM, EDX, Electrical Properties

Microplastics extraction from oyster tissue v1
Authors: Mingoa Benjamin-Rafael , Anand Archana
Published: September 2024

Microplastics are defined as any plastic particles that are smaller than 5mm. They have been found in many of our household products, such as detergents, toothpaste, and other beauty products such as exfoliants. It has also been found that clothes with synthesized fibers, such as acrylics, nylon, and polyester shed hundreds of thousands of microplastic particles every time you wear or wash them. Due to the size of microplastics, they easily pass through many water filtration systems and end up in bodies of water, such as the San Francisco Bay or the Pacific Ocean. This protocol describes the procedure to extract and quantify microplastics in oyster tissue.

Authors: Wickramasinghe Vathsala , Seneviratne Thushari
Published: September 2024

The literature suggests that students commence university education with limited levels of IL, and this is true for both developed and developing countries. When universities understand entry-level students’ actual level of IL at the beginning of their undergraduate programmes, universities can objectively describe entry-level undergraduates’ IL levels and take steps to improve the levels to match with required revels for academic success. The purpose of the study was to investigate the information literacy of first-year undergraduates of engineering, architecture, and information technology disciplines when they commence their university education, and whether socio-demographic characteristics are associated with the information literacy of first-year undergraduates. 545 first-year undergraduates covering the three study disciplines responded to the survey questionnaire. Quantitative methods were used to analyse the data. Findings revealed that although information literacy exists in undergraduates to a certain extent, these vary by the discipline of study. The findings imply the need of addressing information literacy requirements by the discipline of the study to better serve undergraduates. Overall, the results lead to understanding information skills and behaviour of entry-level undergraduates, and what kinds of library services are appropriate and necessary for undergraduates across disciplines.

Published: September 2024

This study aims to determine the level of OPAC accessibility in SLiMS and INLISLite applications. Four main guidelines on website accessibility will be analyzed: perceivable, operable, adaptable, and robust. The four guidelines are based on the Web Content Accessibility Guidelines (WCAG). This study uses a quantitative approach with descriptive methods and data analysis techniques using manual checks based on the WCAG-EM guidelines, which focus on two levels, namely A and AA. The results of the study based on four indicators are (1) perceivable on SLiMS and INLISLite experiencing problems in providing alternative text, (2) operable on SLiMS and INLISLite found problems in the focus element, (3) understandable on SLiMS and INLISLite fail to meet the criteria for providing language, and (4) robust, both applications have succeeded in utilizing HTML syntax according to the provisions. Thus, from the four indicators, the SLiMS and INLISLite applications still need to meet several criteria at level A, namely the criteria for using language, using color, and providing alternative text on non-text elements. Meanwhile, at level AA, there is a failure in the focus element.

Published: September 2024

This research is a bibliometric study using Lotka's Law. Lotka's Law describes the frequency of publications by authors in a particular field. According to Lotka, there is an inverse relationship between the number of articles written and the number of authors who write articles, namely the more articles written, the fewer authors write them. This research aims to determine the pattern of writer productivity according to Lotka's law in the Edulib journal. The object of this research is articles in the Edulib journal with a publication period of 2011-2021. The data collection method in this research was carried out by documentation and then tabulated in table format using MS Excel. Article obtained from the page https://ejournal.upi.edu/index.php/edulib/issue/archive. The articles collected were 166 articles written by 206 different authors. In this research, the "Straight Count" technique was used, namely only the main author or first author was counted. Because there are 79 authors as second authors, the number of authors calculated is 127. The calculation results show that the parameter value n is 2.6895 and C is 0.7985. This means that in 2011-2021 the number of authors who contributed one article was 79.85% of the total number of authors. The results of this research also show that the largest number of author collaborations is five authors in producing one article. The author listed as the first author who was most productive in producing articles was Doddy Rusmono with a contribution of 6 articles.

Health Effects Of Using Visual Display Terminal
Authors: Yurt Ak Yasemin
Published: September 2024

Screen devices are widely used office tools around the world. We are also known as Visual Display Terminal (VDTs). The use of VDT causes health hazards due to the need for high levels of attention and concentration and constant sitting work. Musculoskeletal disorders such as back pain, upper extremity disorders, eye problems, fatigue, and stress are common in VDT users. The computer is a frequently used display device, and computer vision syndrome (CVS) has emerged as a leading occupational health problem. Symptoms of CVS include dry eye, eye fatigue, blurred vision, double vision, redness in the eyes, burning and stinging sensation in the eyes, increase or decrease in tears, double vision, delay in changing focus and color perception irregularities, and deterioration in near vision. Risks arising from screened vehicles can be avoided in healthy and safe working conditions where the work center is set up correctly and breaks are taken at regular intervals. Simple measures such as exercising regularly, taking short frequent breaks, and using a screen filter are important simple interventions to prevent work-related diseases in VDT users. Since VDT use is a frequent part of our lives, we wanted to draw attention to VDT-related disorders and provide simple interventions to prevent them.

Determination of Aloysia citriodora (Palau) phenology and the associated arthropods
Authors: López-Zapata Silvia Patricia
Published: September 2024

Lemon verbena, Aloysia citriodora (Palau) has been widely used in traditional medicine, cosmetics, and the food industry. In Colombia the foliage is marketed fresh but there is no information regarding the plant phenology, nor on the insects associated, therefore the management practices are still empirical, and sometimes does not comply with the national regulations for the commercialization of medicinal plants. In this study it was determined that it takes 32 weeks from planting to flower senescence completing its phenological cycle; likewise, an associated arthropofauna of 50 families with different feeding habits were found, suggesting that the species offers different ecosystem services. The information obtained could contribute to establish more effective management plans for arthropods, and to improve quality of materials with medicinal purposes.

Published: September 2024

The soil organic carbon (SOC) content under climate change scenarios is essential, especially in areas of difficult access such as the high-altitude Tropical paramos. This study aimed to correlate the digital elevation model (DEM) derivatives, spectral indices from Sentinel-1 and Sentinel-2, and WorldClim data with in situ SOC content in the PNR-Cortadera paramo (Boyaca, Colombia). Based on 169 soil samples collected at two depths (0-15 and 15-30 cm) organic carbon was determined using the Walkley-Black method. SOC contents ranged from 25 to 200 t HA-1 at 0-15 cm and from 33 to 466 t ha-1 at 15-30 cm. Altitude, temperature, NDVI, TWI0-15 cm, MRVBF, LS factor0-15 cm and VH band polarization showed the highest correlations and the lowest variance inflation factor. The highest SOC contents are located in the central and southern area of the paramo due to the higher altitude, greater precipitation and presence of vegetation cover.

Published: September 2024

The objective of this research was to evaluate the effect of inoculation and co-inoculation of rhizobia and Azospirillum brasilense combined with humic substances (HS) in growth promotion of Phaseolus lunatus (lima bean) and Leucaena leucocephala (leucaena). For this, experiments in a greenhouse with the cultivation of each plant species were carried out. A randomized complete block experimental design with five repetitions was followed. Plant seeds were sown and then inoculated with rhizobia and co-inoculated with A. brasilense. Subsequently, HS were added at the dose recommended by the manufacturer. In the experiments with both plants, control treatments with the addition of nitrogen (N) with or without HS were used. After 45 days, the shoot dry mass (SDM), root dry mass (RDM), shoot-accumulated N (Nac) and relative efficiency index (REI) were determined. In addition, the mass of dry nodules (MDN) in the lima bean plants and the number of nodules (NN) in leucaena plants were determined. The results showed that in the lima bean and leucaena plants there was a greater increase in SDM, RDM and Nac in treatments that received HS and co-inoculation with rhizobia and A. brasilense than in treatments that were inoculated only with rhizobia and HS and in treatments that received N and HS compared to addition of N and isolated inoculation of rhizobia. The combined application of HS and rhizobia in co-inoculation with A. brasilense had a greater effect on the increase of MDN in lima bean and NN in leucaena, than in treatments where only rhizobia with HS were added. These results indicate the existence of potential interaction of the use of HS with the co-inoculation of rhizobia and A. brasilense, showing promise for the production of sustainable agricultural crops.

Published: September 2024

Weed competition is one of the factors that limit cowpea production in the world, causing losses of up to 90% of grain yield and quality. Knowledge of the critical period of weed competition (CPC) is important to prevent significant losses of grain and resources in the production process. The objective was to determine the critical period of weed competition in the cultivation of cowpea beans, Missouri cultivar, in two sowing seasons: dry (2022B) and rainy (2023A) of warm dry Colombian Caribbean. The randomized complete block design was used with eight treatments and four repetitions. The first four treatments corresponded to manual control of weeds in the intervals 0-10, 0-20, 0-30 and 0-50 days after emergence (DAE), the second four treatments corresponded to the crop-weed coexistence, in the same intervals. Cowpea grain yield, dry mass, cover and weed community composition were evaluated. The critical period of competition of weeds in the cowpea crop for the dry and rainy seasons was 14-33 and 14-29 days after emergence, respectively. The reduction in grain yield was 65.2% in the dry season and 80.46% in the rainy season. Rottboellia cochinchinensis had the highest occurrence rate with 30.3% and a density of 90 individuals per m2; which is important for the agronomic management of the crop in the humid Caribbean subregion.

This study aimed to analyze the toxicological events associated with paracetamol managed by aToxicological Information and Assistance Center. It was a cross-sectional, retrospective study based on casesof toxicological events associated with the drug paracetamol attended by the Toxicological Information andAssistance Center of Londrina (CIATox/Londrina). The data was extracted from the Brazilian Poison DataSystem (DATATOX) from 2017 to 2021. The data was analyzed using the Statistical Package for the SocialSciences (SPSS), version 19.0. This study was approved by the Research Ethics Committee of the StateUniversity of Londrina. Between 2017 and 2021, CIATox/Londrina received 685 cases of toxicologicalevents associated with paracetamol, of which the vast majority (75.0%) were women who had attemptedsuicide (83.2%) as their main circumstance. Most cases (37.7%) occurred in the afternoon on Saturdays andSundays, the days of the week with the highest number of cases (15.7% and 16.2%, respectively).Paracetamol was combined with other substances in 156 (22.8%) cases. Almost 80.0% of the cases hadclinical manifestations, with 36.4% requiring hospitalization (minimum of one and maximum of 37 days).Most cases were categorized as mild (57.7%), and four (0.6%) deaths were identified among all the cases.The antidote N-acetylcysteine was administered to 37.1% (N=255) patients. In general, toxicological eventsassociated with paracetamol occurred predominantly in women in the afternoon and on Saturdays andSundays, and involved suicide attempts. It is, therefore, essential to develop campaigns that encourage thecorrect use of medication and other public health campaigns, especially for those individuals who are moresusceptible to suicide attempts.

Published: September 2024

As infecções sexualmente transmissíveis estão entre os dilemas de saúde pública mais recorrentes da sociedade. A sífilis é uma doença infecto contagiosa, exclusiva do ser humano, transmitida por contato sexual desprevenido. Estima-se que anualmente, 11 milhões de novos casos de sífilis ocorrem em adultos de 15 a 49 anos em todo mundo. O objetivo da pesquisa foi identificar o perfil epidemiológico da sífilis adquirida nos estados da Região Norte do Brasil, entre os anos de   2011 e 2021. Trata-se de uma pesquisa de natureza observacional, com abordagem quantitativa, e retrospectiva, com levantamento de dados do SINAN, disponíveis no DATASUS. Foram analisadas as variáveis sociodemográficas: sexo, idade, raça, nível de escolaridade e critério de diagnostico. Verificou-se que entre 2011 e 2021, nos estados da Região Norte do Brasil, foram notificados 50.810 casos de sífilis adquirida. O estado do Amazonas apresentou a maior taxa de notificações com 18.709 (36,82%) casos, seguido pelo estado do Pará com 13.102 (25,79%) notificações e o Tocantins com 6.728 (13,24%) casos notificados. O ano de 2018 apresentou a maior taxa de incidência do período, diminuindo a partir de 2019. Assim, o perfil da sífilis adquirida na Região Norte foi: indivíduos do sexo masculino, com idade entre 20 e 39 anos, pardos, com escolaridade desconhecida, e em relação ao critério de diagnostico o diagnóstico laboratorial apresentou a maior taxa de notificações. Dessa forma, evidencia-se a necessidade de promover ações com o objetivo de elucidar a saúde sexual e oferecer medidas efetivas no combate à sífilis na população mais acometida, bem como é indispensável uma reavaliação dos campos de preenchimento obrigatórios das fichas de notificação e investigação do SINAN, uma vez que representam uma fonte essencial para determinação dos indicadores de saúde

Com isso, o objetivo deste trabalho foi avaliar o perfil epidemiológico das fraturas de terço proximal do fêmur tratadas de forma cirúrgica no ano de 2021, em hospital privado de São Paulo, Brasil. Trata-se de um Estudo observacional, descritivo e transversal, que buscou avaliar, através de variáveis qualitativas, a prevalência das fraturas de terço proximal do fêmur tratadas de forma cirúrgica, e para avaliar a distribuição dessas variáveis foi aplicado o teste Qui-quadrado de aderência e para avaliar as diferenças conforme o sexo do paciente foi aplicado o teste Qui-quadrado de independência. A fonte para coleta de dados estatísticos foi através do Sistema de Informação Hospitalar- SIH, DATASUS do Ministério da saúde. Como resultados, destacou-se o sexo feminino com 64,30%. Quanto à faixa etária constatado que as fraturas aumentam exponencialmente com o avanço da idade, e as maiores taxas foram observadas na faixa etária de 80 anos ou mais. Analisando o local da fratura verificamos que as transtrocanterianas com 57,8% são mais prevalentes, seguida pela do colo do fêmur com artroplastia parcial de quadril com 24,2%. Quanto ao mecanismo de trauma, destacando-se a queda da própria altura (trauma de baixa energia) com 81,94%, os demais em menor proporção o acidente automobilístico com 10,28%, queda de nível superior com 5,69% e o atropelamento com 2,09%. Diante do exposto, torna-se evidente a importância e necessidade de realizar medidas preventivas a quedas, além de reconhecer os fatores de risco de fraturas para assim realizar orientações necessárias para a sua prevenção.

É visto que o manejo correto de um paciente autista em consultório odontológico ainda é uma grande incógnita, sendo motivo de muita insegurança por parte dos Cirurgiões-Dentistas. Muitas vezes apenas o uso de métodos não farmacológicos em consultório odontológico não é suficiente para oferecer um tratamento seguro e tranquilo, podendo assim, lançar mão da sedação consciente com os benzodiazepínicos. Este trabalho tem como objetivo revisar a literatura sobre as indicações da sedação medicamentosa com Midazolam e Diazepam em pacientes com transtorno do espectro autista. Trata-se de uma revisão de literatura do tipo integrativa, realizada através de uma pesquisa bibliográfica, utilizando Pubmed, Scielo, Lilacs e busca manual. Utilizando os descritores, foram encontrados 53 artigos, dos quais 3 atenderam os critérios de inclusão. Mesmo com a limitação de artigos relacionados, o Midazolam e o Diazepam oferecem uma sedação consciente segura ao paciente com transtorno do espectro autista, em que o Midazolam demonstrou melhores resultados em relação ao Diazepam em tempo de ação, oferecendo uma resposta mais homogênea ao paciente, possibilitando um atendimento mais seguro e tranquilo para os envolvidos.

As abordagens lúdicas utilizam o brincar como estratégia principal durante a internação, estimulando a imaginação e a criatividade ilimitada das crianças. Essas atividades estão diretamente relacionadas ao cuidado de enfermagem, uma vez que a equipe de profissionais dedica mais tempo aos pacientes. O objetivo deste estudo foi identificar as atividades lúdicas utilizadas com crianças com câncer e sua importância no contexto hospitalar. Foi realizada uma revisão integrativa da literatura, entre 2017 e 2023, nas bases de dados LILACS, MEDLINE, BDENF, PubMed, Web of Science e SciELO, sobre o tema pesquisado. Sete artigos foram selecionados. A utilização dessas atividades lúdicas visa tornar a internação hospitalar mais prazerosa e menos estressante, além de contribuir para o bem-estar emocional das crianças hospitalizadas. No entanto, a equipe de enfermagem enfrenta dificuldades na aplicação de estratégias lúdicas durante a assistência e na realização de procedimentos invasivos e dolorosos. A integração dessas atividades na assistência de enfermagem a crianças hospitalizadas com câncer tem demonstrado melhorias na qualidade de vida durante o tratamento, reduzindo estresse e ansiedade, promovendo socialização e expressão de sentimentos. Portanto, é fundamental superar as dificuldades enfrentadas pelos profissionais para garantir o bem-estar das crianças com câncer e de seus cuidadores durante a internação.

Câncer infantil é uma doença crônica que está associada ao risco iminente de morte. A terapêutica localiza-se nas grandes cidades que possuem os Centros Especializados em Oncologia. É neste contexto que as Casas de Apoio se fazem importante para as crianças e suas famílias que não possuem condições financeiras para manter-se. O lúdico que é próprio da infância, proporciona momentos de distração e bem-estar nas diversas atividades que são capazes de instigar a imaginação. O presente trabalho tem por objetivo relatar a experiência de academicas de enfermagem acerca do impacto do voluntariado em uma casa de apoio. Trata-se de um estudo descritivo, desenvolvido a partir da vivencia de academicas de enfermagem durante atividades voluntárias em uma casa de apoio à criança com câncer e sua familia em João Pessoa-Paraíba, durante os meses de outubro de 2023 até abril de 2024. As ações ludicas foram ofertadas a crianças na faixa etária de 6 a 12 anos, de forma individual ou coletiva e com a integração dos pais no momento de cuidado. A  descrição da vivência estruturada em três momentos: cuidar por meio do lúdico; cultivando laços com a criança e sua familia; satisfação em cuidar. O cuidado voluntário à criança com câncer colaborou com o aprofundamento de habilidades humanas essenciais a prática de enfermagem, bem como ampliou o olhar da discente acerca da implementação de abordagens humanísticas de cuidar em oncologia pediátrica.

The banking industry has undergone a significant transformation as a consequence of the increasing emphasis that has been placed on meeting the expectations of clients. Customers who have a solid grasp of technology and who routinely interact with cutting-edge developments assume that banks will provide experiences that are straightforward and easy. In order to facilitate activities such as the use of “digital currency, electronic banking, and the transfer of physical cash”, financial institutions have extended their scope of operations to include the retail, information technology & telecommunications industries. Users have profited from the ease of being able to access banking services around the clock as a consequence of these developments; nonetheless, the financial system has also been badly impacted as a result of these innovations. In addition to this, the research explores the positive & negative factors that are related with the use of artificial intelligence technology in the banking sector of India. The purpose of this research is to provide a descriptive analysis of the implementation of “Artificial Intelligence (AI)” in the financial services sector and the influence that it has on interactions with clients. A total of 197 customers from public & private banks in Gujarat participated in the research project by filling out a questionnaire and providing their data. This was done in order to understand their perspectives & experiences.

Compreender a perspectiva de profissionais de enfermagem sobre a assistência ao parto em um hospital-escola do oeste do Paraná na ótica da advocacia da parturiente. Pesquisa qualitativa, com profissionais de enfermagem, realizada por meio de entrevista presencial e de ligação de voz, entre dezembro de 2019 e julho de 2020. Os dados foram analisados pela análise temática de conteúdo. Participaram 20 profissionais, 5 enfermeiras e 15 técnicas de enfermagem. Foram identificadas cinco categorias: privacidade e conforto; orientação sobre parto e as escolhas da parturiente; presença do acompanhante; autonomia da enfermagem no processo de parto; e práticas inadequadas. A assistência à parturiente apontou avanços no uso de práticas adequadas. Concernente a isso, o profissional de enfermagem se mostrou como advogado da parturiente, defendendo-a de práticas inadequadas que, embora menos presentes, ainda permeiam o cenário de parto e nascimento.
