Authors: Siddiqui Saharoj , Singh Priyadarshini Shah , Pandey Aashish , Gurung Nandita , Shukla Ambalika , Shah Ashutosh Kumar
Published: November 2024

Background: The growth in alcohol consumption is skyrocketing. Alcohol ranks first as the most commonly misused substance by medical students. Considerably more stress has been documented among medical students. They tend to consume alcohol to cope with stressful situations. Excessive drinking can lead to consequences like loss of concentration and poor performance in academics. While there is extensive research on alcohol consumption patterns in various populations, there is a notable scarcity of localized studies, particularly in medical schools in periphery of Nepal. This study aims to fill the gap by providing specific data on the status of alcohol consumption among students at Nepalgunj Medical College. Methods: A descriptive cross-sectional study was carried out among medical students of Nepalgunj Medical College. Results: Among 406, 15% (61) consumed alcohol. Among the alcohol consumers, 15% were CAGE positive and possibly have alcohol problems and all of them were male. About 32.8% of them initiated drinking due to peer pressure, 29.5% of the students started out of curiosity. Conclusion: The prevalence of alcohol consumption is comparatively lower among medical students in Nepalgunj Medical College. However, the alcohol problem is more among the drinkers. Alcohol problem is very common in male and final-year students. The most common reasons for initiation of drinking by them is peer pressure. Further studies regarding alcohol abuse pattern, its determinants, and treatment among the medical students are the current necessities to apply the proper interventional strategies to ensure the production of compatible and genuine doctors in the future.

Published: November 2024

Background and Aim: The required nursing care when missed can be detrimental to the life of the patient. This study focused on exploring the insights of nurses when they omit care, identifying the factors contributing to these incidents, and examining how nurses cope with missed nursing, which plays a pivotal role in patient outcomes. Design: Using a qualitative, case study design, data were collected from 10 registered nurses working in ward departments from different hospitals in Iligan City through semi-structured interviews. Results and Discussion: Nurses perceived missed care as a form of malpractice and negligence, as evidenced by the failure to provide essential care in their duty. These occurrences are linked to busy work schedules and stressful work environments. The study also revealed that nurses experience a range of emotions after dealing with missed care including fear and guilt. Seeking support, guidance, and self-reflection are strategies for addressing missed nursing care. Conclusion: Nurses emphasized that using an adaptive strategy can minimize the occurrence of missed care and its emotional impact. The study reveals that nurses suffer a range of emotions but still retain their professional responsibility as nurses. Creating a supportive work environment, promoting ongoing professional growth, and encouraging self-reflection among nurses are essential steps toward reducing missed care incidents.

Allogeneic hematopoietic stem cell transplantation (HSCT) is the curative treatment option for a variety of hematological disorders. Usually, stem cells for HSCT are obtained from matched related donors through bone marrow harvest or apheresis. Although stem cell donation is relatively a safe procedure, there are many psychosocial concerns among potential donors regarding the donation of stem cells and its possible complications. The present study aims to understand the experience of being a hematopoietic stem cell donor for a sick sibling. Eighty hematopoietic stem cell sibling donors were interviewed with a self-structured questionnaire comprising of 3 domains-intrinsic and extrinsic motivators and deterrents. Data were analyzed using descriptive and inferential statistics using IBM SPSS® Statistics version 20.0. The present study found that nearly half of them (47.5%) were <30 years of age with 52.5% being male, 57.5% were married and 53.8% were employed. 43.8% were graduates of which 7.5% had a family income of <Rs.5,000. 51.2% hailed from rural backgrounds. The majority of them (90%) of them had no co-morbidities. All of them underwent local anesthesia and had peripheral stem cells as the source of harvest. None of them had a previous history of stem cell donation. The majority of the matched sibling donors were primarily influenced by intrinsic factors (median score-3.2). The influence of the deterrents is lesser than the influence of the motivators (median score-1). There is a statistically significant association between gender and the influence of extrinsic motivators (P = 0.024), marital status and deterrents (P = 0.003), and age and deterrents (P = 0.019) in the hematopoietic stem cell donation process. Among the deterring facets, the emotional concern of being responsible for the outcome of the transplant was the major barrier (45%). The family concern of taking up the burden of being a donor and a family member is the least deterring facet (62.5%). Among the intrinsic motivating facets, positive feelings (87.5%) and family loyalty (81.3%) were the major motivating factors whereas reinvesting back into the community was the least intrinsically motivating factor (32.5%). Among the extrinsic motivating facets, complete awareness of the donation process through explanation was the highly motivating factor (93.8%). Family pressure/social obligation was the least extrinsically motivating facet (83.8%). The study highlights the role of intrinsic motivation in the stem cell donation process and warrants for further exploration.

Authors: Lobo Sonia , Bhat Sudhindra
Published: November 2024

The COVID-19 pandemic has significantly impacted the financial performance of various sectors across the globe, including the Indian pharmaceutical industry. This study aims to evaluate the financial performance of ten Indian pharmaceutical companies listed in the S&P BSE Healthcare Index over two distinct periods: before COVID-19 (2018–2020) and during the pandemic (2020–2022). A hybrid multicriteria decision-making (MCDM) approach, integrating the Fuzzy Analytic Hierarchy Process (FAHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), is employed to assess companies based on five key financial dimensions and several performance indicators. Results indicate that profitability, valuation, and growth ratios were the most critical dimensions, with weights of 0.21 each, followed by liquidity (0.19) and efficiency (0.18). Furthermore, among the companies evaluated, Divis Labs and Abbott India emerged as top performers, both during and before the pandemic, with Divis Labs registering closeness coefficients of 0.871 and 0.814 during 2020–2021 and 2021–2022. The findings highlight the financial resilience of these companies, offering valuable insights for stakeholders in formulating strategies to sustain financial stability during future crises.

Authors:   PhD Research Scholar, Lincoln University. Malaysia, I.S.K Eriyagama
Published: November 2024

The flipped classroom approach is a blended learning model concerning developing digital literacy skills in the 21st century. Hence this study was launched to find out the mathematic teachers’ perceptions of flipped classrooms towards digital literacy skills and to identify the opportunities available for the mathematics teachers to enhance their experience in flipped classroom approaches. The mixed method research design was used and the Likert scale questionnaire was administered to randomly selected 244 mathematics teachers, from the school in Galle education division, Sri Lanka. Face-to-face interviews were conducted with randomly selected 10 mathematics teachers from the sample to data triangulation, Data were analyzed quantitatively using SPSS (Version 25) software. The result showed that the majority of the (71.3%) sample was in the view that the flipped classroom approach can promote teachers to become organizers of information literacy. Furthermore, most teachers (78.7%) agreed that the flipped classroom approach can communicate students’ ideas with each other by utilizing multiple media and technologies. In addition, 80.7% of the sample point out that the flipped classroom approach promotes both teachers’ and students’ computer literacy skills. The findings also revealed statistically significant differences at (α≤ 0.05) on the total degree of perceptions towards digital literacy skills due to gender since (0.00) is less than (0.05). It was revealed teachers’ perceptions were, that digital skills could be developed through this approach, but lack of adequate technological resources at school and home, poor internet connectivity in rural areas and students still depending on the teacher to learn mathematics were identified factors that obstacles to enhancing this approach to a practical level in Sri Lanka.
Fish as an Epitome of a Rich Cultural History: Documenting the Cultural and Socio-religious Practices Surrounding Fish in Fish-loving Bengali Societies
Authors:   Research Assistant, Cooch Behar Panchanan Barma University, West Bengal, India, Chakraborty Shrestha
Published: November 2024

It is not just about a fine luncheon packed with omega-3 fatty acids and proteins that a fish caters to us. Rather it is like an intense passion for the fish rising from the deepest part of a Mecho Bengali’s (Bengali people who love to eat fish) heart which goes to the extent of being reflected as an eye catching moment in a wedding or in a temple where fish plays a significant role ranging from its rituals to recipes. We, the Bengali people, not only use fish in our food but also worship them. Fish is considered very auspicious and lucky before starting something good and important in our life as the fish (one of the ten incarnations of Lord Vishnu) becomes the rescuer of all living beings during the time of the great flood as is stated in the ‘Matsya Purana’. Since ancient times fish has been considered a symbol of divine power and luck. This paper has put forward an honest effort to develop an understanding of the social, cultural, and religious significance of fish in Bengali societies. From economic importance in the fishing industry to folklore, mythology, religion, art, and literature, fish plays a significant role. In a wedding, there are some rituals related to fish starting from the Tatta to the bride’s welcoming day and then there is a sudden shift in this discourse. And this shift is found in the fish bhog tradition that the paper also tried to brief in this very discourse.
Whose Quest for Identity?: The Kaivartta Rebellion in the Ramacharitam of Sandhyakaranandin
Authors:   Post Graduate Student, The Department of History, Jadavpur University, Kolkata, India, Dutta Gupta Diptangshu
Published: November 2024

The Kaivartta Rebellion in Pala Bengal was a decisive event that severed the Varendra region from Pala control, which was the janakabhu of the Palas at a time when the Pala Empire was embroiled in succession politics threatened by the fluctuating loyalty of the samanta chiefs. The only mention of Kaivartta Revolt we find is in the Ramacharitam written by Sandhyakaranandin, dedicated to Emperor Ramapala. This paper aims to identify the different quests for identity during the uprising of the Kaivarttas. There are different historiographical interpretations behind the causes of the uprising, but what this paper focuses on is how this revolt facilitates many identity creations. For the Kaivarttas the revolt was to claim an identity for upward social mobility. The same goes for the samantas, whose relationship with the Pala overlords was one of political reciprocity. The samantas were also looking for political independence and were in search of a stronger alliance with the overlords. Apart from the ritual upliftment, the land was itself an important asset and a source of power for upward social mobility which the Kaivarttas did so claiming their identity as farmers from fishermen. For the author himself, the writing of the text itself was a challenge that might enable him to end up at the Pala court where he will be royally patronised. Towards the end, Ramapala’s quest for political legitimation can be understood in the context of this rebellion as artfully justified by the author Sandhyakaranandin.

The integration of artificial intelligence (AI) in creative writing has sparked a global interest in how it might impact the creativity of aspiring writers. The Natural Language Generation (NLG) technology has enabled AI to generate written materials that imitate patterns and structures of human language. This paper aims to investigate the impact of generative AI tools on creative writing, with a focus on emerging Bangladeshi writers. It also underscores the crucial role of user responsibility when using AI tools for creative writing. For this study, six renowned Bangladeshi authors and academicians and fifteen aspiring writers shared their insights on whether AI is a transformative tool that amplifies the writer’s creativity and efficiency or if it poses a threat to the inventiveness of novice writers. The findings show that AI can facilitate idea generation, accelerate the writing process, provide feedback to developing structure, and improve the language skills of aspiring writers. However, it was observed that the responses provided by AI were generic and repetitive. The writers who use AI particularly mentioned its inability to create unique content with emotional depth and originality, which are distinguishing features of human creativity. Furthermore, the renowned authors emphasized the ethical concerns they have about the authorship and authenticity of the content produced with AI assistance. They also feared that over-reliance on AI tools might lead to homogenization in creative writing.
Da Lei Bosman ao sportswashing
Authors: Carvalho Renan Augusto , Almada Pablo Emanuel Romero
Published: November 2024

O artigo investiga a relação entre a globalização, o neoliberalismo e o futebol contemporâneo, analisando como essas forças transformaram o esporte em um fenômeno transnacional que reflete e reproduz as desigualdades e contradições do capitalismo moderno. Baseando-se em uma abordagem teórica que considera a racionalidade neoliberal como uma lógica abrangente que permeia diversas esferas da vida social, o estudo explora os impactos econômicos, políticos e culturais dessa racionalidade no futebol global. Para tanto, são analisados dois casos emblemáticos: a Lei Bosman e a prática de sportswashing por clubes europeus, como Manchester City, Newcastle United e Paris Saint-Germain. Através desses casos, o artigo demonstra como o neoliberalismo reconfigura as dinâmicas de poder, subjetivação e governamentalidade no esporte, transformando jogadores em mercadorias e instrumentalizando o futebol para fins geopolíticos. Conclui-se que a racionalidade neoliberal, ao penetrar no futebol, não só redefine práticas sociais e culturais, mas também propõe desafios para a resistência e a manutenção dos vínculos locais e comunitários.

Faith, Politics and Eschatology in the Thought of Joseph Ratzinger
Authors: Rowland Tracey
Published: November 2024

This paper situates the political theory of Joseph Ratzinger within the tradition of St. Augustine and argues that while his position on the liberal tradition is in some ways ambivalent, he is closer to the British Tory tradition than to the British Whig Tradition.  Ratzinger emphasises that Christian faith destroyed the myth of the divine state and replaced it with a conception of the state governed by ‘the objectivity of reason’ and for Ratzinger ‘true human reason involves morality, which lives on God’s commandments’. Ratzinger strongly opposed the alignment of politics with eschatology.
Human Rights at the United Nations: In a Tension Between Universality and Ambivalence
Authors: Peeters Marguerite A.
Published: November 2024

This paper analyzes the tension, within the context of the United Nations, between the proclaimed universality of human rights since 1948 and the progressive destabilization of their core content, in a dramatic momentum since 1968. The paper identifies key milestones in this process. It uses a historical approach revisiting the context in human rights integrated the UN mandate and were later interpreted at major international conferences, focusing on the leadership of feminist individuals and lobbies. It relates the tension between universality and ambivalence to a conflict between two opposed anthropological perspectives, viewing the human being either as a person endowed with a given nature, or as an individual with the power to freely choose how to construct itself. Those upholding the former view may not always have reached as clear a consensus as generally assumed on the very concept of person. The way forward may be to complete the past anthropological underpinnings of universal human rights with the development of an ontology of love.

Authors:   , Leite Helia Maria de Souza
Published: November 2024

Objetivou-se com o estudo avaliar o efeito de diferentes proporções de dietas de
alto grão na terminação de cordeiros em sistema de confinamento sobre o desempenho e
alterações no comportamento ingestivo e fisiológico, assim como as características de
carcaça, qualidade físicas e químicas da carne e custos de produção. Utilizou-se para tal, grão
de milho inteiro associando ao suplemento protéico-mineral-vitamínico em três proporções de
concentrado:volumoso, (100%, 80:20% e 60:40%), sendo a porção concentrada da dieta
composta de 85% de grão de milho inteiro e 15% de suplemento e a porção volumosa de feno
de Tifton). Foram utilizados 24 machos não castrados, sem padrão racial definido com peso
inicial de 20,9 ± 1,0kg com idade de 6 meses. Conseguiu-se obter ganhos de peso nas três
dietas testadas de 0,302g/dia para dieta 100%, 0,254 g/dia para 80:20 e 0,259 g/dia para 60:40
O tempo de ruminação foi menor (P≤0,05) nos cordeiros do tratamento à base de grão 100%
quando comparados aos cordeiros dos demais tratamentos. A dieta 100% apresentou maior
eficiência de alimentação (EAL) e também mais eficiente na ruminação (ERU). Avaliando a
temperatura da região do rúmen percebe-se que os animais que receberam a dieta 100%
apresentaram acentuada variação de temperatura da região do rémen, as dietas 80:20 e
60:40% apresentam alterações de temperaturas próximas. As dietas avaliadas contribuíram
para o desempenho com ganhos satisfatórios, apesar de ocorrer alterações comportamentais
com uso da dieta de alto grão, estas garantem as ações básicas necessária para manter a saúde
ruminal adequada. Houve efeito significativo para rendimento de carcaça. A dieta 100%
concentrado apresentou um rendimento de carcaça de 47%, enquanto as dietas 80:20% e
60:40% obtiveram valores para rendimento de carcaça de 43,5% e 43,4% respectivamente. O
conteúdo gastrointestinal também apresentou efeito, sendo menor nos tratamentos 100% e
80:20%. Para os parâmetros físicos da carne, não foi observado diferenças significativa
(P>0,05) nas variáveis pH, temperatura, cor, capacidade de retenção de água e força de
cisalhamento. O tratamento 100% apresentou uma menor perda de peso na cocção assim
como também apresentou ácido tiobarbitúrico (TBARS) superior quando comparado as
demais dietas. A dieta 100%, quando comparado as demais dietas, obteve-se um peso
adicional de carcaça de 2,30 Kg por animal. O uso da dieta 100% concentrado em sistemas de
terminação de cordeiros é a alternativa mais viável do ponto de vista produtivo e econômico
Desenvolvimento dos pré-estômagos de bezerros mestiços aleitados com leite em pó associado ao soro de queijo em pó
Authors:   , Miranda Maria Vivianne Freitas Gomes de
Published: November 2024

Objetivou-se avaliar o desenvolvimento dos pré-estômagos, o crescimento e a taxa de proliferação celular das papilas ruminais, em bezerros aleitados com sucedâneos (leite em pó e soro de queijo em pó) durante os 60 primeiros dias de vida. Verificar se a dieta pode influenciar as células produtoras de quimosina e pepsinogênio. Para isso, 24 bezerros mestiços com uma semana de vida foram distribuídos em um delineamento inteiramente casualizado com 4 (quatro) tratamentos e 6 (seis) repetições: LI: leite integral (Controle); LP: leite em pó; LPS1: 80% leite em pó + 20% de soro de queijo em pó; LPS2: 60% leite em pó + 40% de soro de queijo em pó. Para os cálculos de consumo de matéria seca (MS) foram feitas medições diárias de consumo de feno e concentrado pelo método de oferta/sobra. Os animais foram abatidos aos 60 dias de vida. Os órgãos cavitários foram pesados com conteúdo, e logo em seguida, esvaziados e novamente pesados, registrando-se, os pesos cheios e vazios, respectivamente. Foi determinado o peso dos estômagos e de seus compartimentos com valores absolutos (kg) e relativos (%) em função do peso de corpo vazio (% PCVZ) e em função do peso do estômago completo (% PE). Foram retirados fragmentos de aproximadamente um centímetro quadrado (1cm2) de tecidos de 4 regiões do rúmen: átrio ruminal, saco dorsal, saco cego caudo-dorsal e saco ventral de onde foram medidas as alturas das papilas ruminais. A atividade proliferativa foi avaliada em amostras de tecidos retiradas do rúmen por meio da contagem de Regiões Organizadoras de Nucléolos Argirofílicos (AgNOR). Foram coletadas amostras teciduais de 1cm2 do abomaso para a realização da imunohistoquímica. Não houve diferença significativa para o consumo de matéria seca (P>0,05). As médias obtidas para pesos absolutos e relativos em função do peso do corpo vazio dos compartimentos gástricos não apresentaram diferenças significativas (P>0,05) entre os tratamentos. Quanto ao desenvolvimento de papilas no rúmen houve diferenças significativas (P<0,05) para a variável altura no saco ventral, onde os animais que receberam leite integral possuíram maiores médias. Não houve diferenças significativas (P>0,05) para a taxa de proliferação celular nas papilas ruminais. Os percentuais de ácinos contendo células imunorreativas aos anticorpos quimosina e pepsinogênio apresentaram diferença estatística (P<0,05), onde os bezerros que receberam a dieta 100% leite integral, apresentaram média percentual de marcação para quimosina superior (95,11%), aqueles animais que consumiram a dieta 60% leite em pó + 40% de soro de queijo em pó (89,59%)
Caracterização de subprodutos do processamento de uvas produzidas no Vale do São Francisco
Authors:   , Ribeiro Thalita Passos
Published: November 2024

O aproveitamento de subprodutos da agroindústria pode trazer oportunidades para a geração de novos produtos, incluindo alimentares. Esse potencial pode ser maior quando a matéria-prima possui composição química diferenciada, a exemplo das uvas. Para esta fruta, a avaliação segura dessas potencialidades, requer estudos detalhados sobre a qualidade e as características funcionais do subproduto gerado durante a vinificação e a elaboração de suco. Assim, o objetivo geral deste estudo foi caracterizar os tipos de subprodutos gerados pelo processamento de diferentes variedades de videira nas empresas sediadas no Vale do São Francisco, como suporte ao aproveitamento agroindustrial daqueles reconhecidamente com maiores teores de compostos químicos de interesse e alta atividade antioxidante. Foram avaliados acidez titulável, teores de ácido ascórbico, sólidos solúveis, açúcares solúveis totais, proteínas, compostos pécticos, polifenóis extraíveis totais, taninos condensados, antocianinas, flavonoides amarelos e atividade antioxidante, pelos métodos do ABTS e DPPH das uvas e dos subprodutos (cascas e sementes) gerados na vinificação e durante a elaboração de sucos de diferentes variedades. Os subprodutos amostrados foram resultantes do processamento de vinhos brancos/espumantes das variedades Viognier, Chenin Blanc, Moscato Canelli, Italia, Arinto + Fernão Pires, Tempranillo, Grenache, Mourvèdre, Verdejo e Sauvignon Blanc, bem como do processamento de vinhos tintos de ‘Tempranillo’, ‘Cabernet Sauvignon’, ‘Syrah’ e ‘Alicante Bouschet’. Subprodutos gerados do processamento de sucos das variedades Isabel Precoce, BRS Cora, BRS Violeta, BRS Carmem e Bordô também foram avaliados. O estudo seguiu o delineamento experimental inteiramente casualisado, com quatro repetições. Os dados foram submetidos à análise de variância em separado para cada processamento e as médias foram comparadas pelo teste de Tukey (P<0,05). Os subprodutos de casca e sementes, em geral, apresentaram elevados teores de ácido ascórbico, proteínas, polifenóis, antocianinas, taninos condensados e alta atividade antioxidante. Por conseguinte, o aproveitamento dos subprodutos do processamento de uvas pode ser uma alternativa para a geração de novos produtos alimentares. Entretanto, ressalta-se que os teores não foram uniformes para uma mesma variedade e para um mesmo tipo de processamento, requerendo formas diferenciais de aproveitamento dos seus subprodutos entre as empresas. O estudo apontou que os principais subprodutos do processamento de diferentes variedades que podem ser aproveitados foram os de ‘Syrah’ e ‘Alicante Bouschet’, resultante da elaboração de vinhos tintos, ‘Tempranillo’, da elaboração de vinhos brancos/espumantes, e ‘BRS Violeta’, gerados na elaboração de sucos
Otimização da adubação fosfatada para a cultura da melancia irrigada em ambiente semiárido
Authors:   , Pereira Natanael Santiago
Published: November 2024

A cultura da melancia tem grande importância econômica e social para o semiárido

nordestino, existindo uma grande demanda por informações para um manejo adequado das

adubações, particularmente para o P, em razão de sua dinâmica no solo e por sua baixa

disponibilidade em muitos solos da região. Nesse contexto, o objetivo com este trabalho foi

avaliar a produção, qualidade e o acúmulo de nutrientes pela melancieira cv. Magnum sob

influência do manejo da adubação fosfatada. Os experimentos foram realizados em um

Cambissolo de origem calcária de textura média (Upanema-RN) e em um Argissolo de textura

arenosa (Mossoró-RN), no delineamento experimental de blocos ao acaso, com quatro

repetições. Em solo calcário, os tratamentos consistiram nas doses de 76, 168, 275 e 397 kg ha-

1 de P2O5, as quais foram aplicadas de duas formas: F0- em pré-plantio e F1 – em pré-plantio +

cobertura (50 kg ha-1 de P2O5 por fertirrigação). Foram aplicados ainda dois tratamentos

adicionais: sem fosfato; e com fosfato somente por cobertura (50 kg ha-1 de P2O5 na

fertirrigação). No experimento realizado em solo arenoso, os tratamentos consistiram nas doses

de 34, 80, 168 e 206 kg ha-1 de P2O5, as quais foram aplicadas de duas formas: F0- em préplantio

e F1 – em pré-plantio + cobertura (34 kg ha-1 de P2O5 por fertirrigação), sendo aplicados

ainda dois tratamentos adicionais: sem fosfato; e com fosfato somente em cobertura (103 kg ha-

1 de P2O5 por fertirrigação). Em solo calcário houve efeito isolado de doses e formas de

aplicação sobre as características de produção, com destaque para a maior dose da adubação F1

em relação a F0. Porém, de forma geral, o tratamento adicional com 103 kg ha-1 de P2O5 na

fertirrigação mostrou ser mais eficiente, com produtividade comercial equivalente a uma dose

de 204 kg ha-1 de P2O5 na adubação F1. A adubação F1 proporcionou maiores acúmulos de P e

de S, porém, de forma geral, os efeitos das formas de adubação foram dependentes das doses,

destacando-se os tratamentos F0275 e F1168 em termos de acúmulo de biomassa e dos demais

macronutrientes. Em solo arenoso, houve efeito isolado de doses e formas de aplicação sobre

as características de produção, com destaque para a maior dose da adubação F1 em relação a

F0. Porém, de forma geral, o tratamento adicional com 103 kg ha-1 de P2O5 na fertirrigação

mostrou ser mais eficiente, com produtividade comercial equivalente a uma dose de 204 kg ha-

1 de P2O5 na adubação F1. Na dose de 137 kg ha-1 de P2O5, maiores acúmulos de P, tanto na

parte aérea, como nos frutos ocorrem na adubação F1. Para Ca e Mg ocorreram maiores

acúmulos com a adubação F1 apenas na parte vegetativa. De forma geral, cerca de 50% da

demanda total dos macronutrientes ocorre no quarto final do ciclo
Avaliação de sistema de tratamento da água cinza e reúso da água no semiárido brasileiro
Authors:   , Feitosa Alex Pinheiro
Published: November 2024

A inadequação dos sistemas de esgotamento sanitário no Brasil tem comprometido a saúde das populações rurais e urbanas e a qualidade do ambiente. Diante desse cenário, e juntamente com a escassez da água de boa qualidade, tem-se estimulado o aproveitamento agrícola das águas residuárias na produção de hortaliças, bem como de outros cultivos agrícolas. Este trabalho objetivou a avaliação de uma estação de tratamento para água cinza empregando radiação ultravioleta (UV) na desinfecção do efluente e o desempenho hidráulico de gotejadores com água cinza. Sendo construída uma estação para tratamento de água cinza localizada no Projeto de Assentamento (P.A.) Monte Alegre I no município de Upanema-RN, microrregião médio Oeste potiguar e um reator com lâmpadas ultravioletas foi instalado no Parque Zoobotânico (PZO) da Universidade Federal Rural do Semi-Árido (UFERSA) Campus Mossoró-RN. A estação de tratamento foi composta por uma caixa de passagem, tanque séptico, um filtro orgânico e um reservatório de armazenamento, já o reator ultravioleta artificial foi construído em alvenaria de tijolos nas dimensões de 1,08 m de largura por 1,18 m de comprimento e 0,40 m de profundidade, onde e foram instaladas duas lâmpadas germicidas UV de 30 W e 254 nm cada. Os tratamentos utilizados na análise do efeito da radiação UV consistiram de três lâminas (0,10 m, 0,20 m e 0,30 m) e cinco tempos de exposição de (0, 1, 2, 3 e 4 h). Para fins de avaliação do sistema de tratamento adotou-se por meio de coleta e análise físico-químicas e microbiológicas dos efluentes coletados em distintos pontos do sistema e o efeito da radiação UV por meio do decaimento do nível populacional de microrganismos. Os dados foram avaliados mediante uso da estatística paramétrica (univariada) e não paramétrica (multivariada), de acordo com a complexidade do grupo de dados. Durante o período experimental foi analisado o desempenho do sistema de irrigação por meio dos indicadores vazão média (Q), coeficiente de variação de vazão (CVQ), coeficiente de uniformidade de distribuição (CUD) e coeficiente de uniformidade estatística (Us). A estação de tratamento foi eficiente na remoção da maioria das características analisadas, visto que estavam dentro dos padrões da legislação vigente. Na avaliação do sistema de irrigação foi notado a formação de biofilme no gotejador e presença de microrganismos. O efeito da radiação foi satisfatório, entretanto evidenciou-se a necessidade do cálculo da dose de radiação, com vistas a melhorar a eficiência do tratamento.

Authors:   , Arruda Luiz Eduardo Vieira de
Published: November 2024

Nas regiões áridas e semiáridas do Nordeste Brasileiro a água é um recurso escasso e sua retirada excessiva, nas últimas décadas, vem acarretando aumento da concentração de sais e, consequentemente, redução da sua qualidade. É necessário conhecer a dinâmica de água e o transporte de solutos no solo, quando estes são aplicados na superfície do solo, com o objetivo de prever sua distribuição espacial, que é fundamental para se estabelecer a melhor maneira de se monitorar umidade, salinidade e nutrientes na zona do sistema radicular das culturas. Para isto, é preciso que o irrigante utilize ferramentas que o auxiliem no manejo da produção agrícola. Objetivou-se com este trabalho avaliar a aplicação do software HYDRUS 2D na simulação da dinâmica de água e transporte de potássio no solo no interior do bulbo úmido sob irrigação por gotejamento superficial. Para isto, foi realizado um experimento em ambiente controlado, em vasos de, aproximadamente, 60 L preenchidos com solo (Cambissolo), onde foram aplicadas três diferentes vazões (0,72; 1,52 e 2,50 L h-1) e três concentrações de potássio (0,165; 0,450 e 0,750 mg cm-3), via irrigação por gotejamento superficial. Para tanto, o experimento foi conduzido com a finalidade aplicação de obter dados de entrada para a simulação com o software HYDRUS 2D e dados para a validação e confrontação com os dados obtidos na simulação do software. O mesmo constou de caracterização inicial do solo e o desenvolvimento dos tensiômetros digitais e sensores de condutividade elétrica do solo com suas respectivas calibrações; montagem dos vasos; condução e monitoramento do experimento durante a aplicação de 5,0 L de solução (irrigação) e posterior redistribuição até 72 h; ao final, determinação dos atributos físicos do solo. Também foram elaboradas Breakthrough Curves (BTC) para determinação dos parâmetros de transporte de potássio no solo; foram realizadas simulações com o modelo HYDRUS 2D; e, posteriormente, a análise estatística do desempenho do modelo HYDRUS 2D utilizando a Raiz do Erro Quadrático Médio (REQM) e o Erro Absoluto Médio (EAM); e, por fim, a análise de sensibilidade do modelo. Verificou-se um bom ajuste entre os dados observados e os simulados com o modelo, para a distribuição e a redistribuição de água e o transporte de potássio no solo, com baixos valores obtidos de REQM e EAM. Pode-se concluir que o modelo forneceu resultados robustos para distribuição e redistribuição de água no solo, em ambiente protegido, sob irrigação por gotejamento superficial, em relação aos dados observados experimentalmente; bem como, para as simulações do transporte e redistribuição de potássio no solo, sob diferentes concentrações da solução aplicada

Published: November 2024

Introduction:

Multimodal medical image fusion techniques play an important role in clinical diagnosis and treatment planning. The process of combining
multimodal images involves several challenges depending on the type of modality, transformation techniques, and mapping of structural and
metabolic information.

Methods:

Artifacts can form during data acquisition, such as minor movement of patients, or data pre-processing, registration, and normalization. Unlike
single-modality images, the detection of an artifact is a more challenging task in complementary fused multimodal images. Many medical image
fusion techniques have been developed by various researchers, but not many have tested the robustness of their fusion approaches. The main
objective of this study is to identify and classify the noise and artifacts present in the fused MRI-SPECT brain images using transfer learning by
fine-tuned CNN networks. Deep neural network-based techniques are capable of detecting minor amounts of noise in images. In this study, three
pre-trained convolutional neural network-based models (ResNet50, DenseNet 169, and InceptionV3) were used to detect artifacts and various
noises including Gaussian, Speckle, Random, and mixed noises present in fused MRI -SPECT brain image datasets using transfer learning.

Results:

The five-fold stratified cross-validation (SCV) is used to evaluate the performance of networks. The obtained performance results for the pretrained
DenseNet169 model for various folds were greater as compared with the rest of the models; the former had an average accuracy of five-fold
of 93.8±5.8%, 98%±3.9%, 97.8±1.64%, and 93.8±5.8%, whereas InceptionNetV3 had a value of 90.6±9.8%, 98.8±1.6%, 91.4±9.74%, and
90.6±9.8%, and ResNet50 had a value of 75.8±21%.84.8±7.6%, 73.8±22%, and 75.8±21% for Gaussian, speckle, random and mixed noise,
respectively.

Conclusion:

Based on the performance results obtained, the pre-trained DenseNet 169 model provides the highest accuracy among the other four used models.

Published: November 2024

This study aims to provide meticulous identification of eight valuable, unpublished gold coins from Abbasid dynasty preserved in the collection of the Bangladesh National Museum and analyze their inscriptions, ultimately exploring their historical significance within the context of early Arab-Bengal trade relations. Discovered in the Chandpur and Brahmanbaria districts near the Samatata archaeological site in 1996 and 2002, these coins are not detailed in the museum’s inventory beyond their discovery and acquisition history. This study reveals key details such as their issuing authority, year of issuance, mint name, metal composition, measurements, and inscriptions that promote Islamic monotheism and praise the Prophet Muhammad. Analyzing the inscriptions on these coins, the study briefly highlights the distinctive features of Abbasid gold coins. These coins represent as essential artefacts in the history of early Arabs and ancient Bengal, prominently featuring commercial symbols. Indirect references in the historical texts from Arab-Persian geographers suggest that Bengal was a flourishing commercial hub in ancient time and well-integrated into maritime trade networks with early Arab merchants. The archaeological evidence of their trading interactions is substantiated by these gold coins, illustrating the extent of this relation spanning from the eighth to the tenth centuries.

Background: Fatigue is one of the common symptoms in patients with chronic medical conditions like kidney failure that require hemodialysis. It is also associated with bad quality of life. Therefore, it is crucial to evaluate it using tools like Fatigue Severity Scale (FSS).
Aim: The purpose of this study was to evaluate the reliability and validity of the translated FSS.
Methods: FSS was performed on 41 chronic kidney patients undergoing dialysis. The FSS used in the study was translated from English to Bahasa Indonesia by the team. The questionnaire was assessed for its reliability and validity using Cronbach’s Alpha (CA) and Pearson Validity Test, respectively. Reliability for each item was also evaluated using the corrected item-total correlation. The scale is reliable if its CA value >0.6 and valid if the r-value is higher than the expected r on Pearson's table.
Results: The scale was perceived as reliable based on the CA values from both respondent groups: 0.968 for HD and 0.952 for the CAPD group. All nine items were also deemed reliable based on the corrected item-total correlation score. Based on both r and Sig values, the translated FSS was valid for all groups: r>0.433 for HD, r>0.444 for CAPD, and Sig value <0.05.
Conclusion:  The translated FSS is valid and reliable, hinting at its ability to be utilized in assessing fatigue in chronic kidney patients on dialysis

Cryptococcosis causes invasive fungal infections and the two common species are cryptococcus neoformans and cryptococcus gattii, which are responsible for the majority of the clinical manifestations. We are presenting a case of a 35-year-old individual who was admitted with the complaints of fever associated with acute onset altered sensorium. His CSF PCR testing showed cryptococcus species, and so diagnosed as cryptococcal meningoencephalitis and then eventually found to have HIV/AIDS. CSF PCR testing can be done rapidly for variety of common bacterial and fungal infections, and its results are available within one hour. The early diagnosis and treatment initiation is very vital in immunodeficiency states such as HIV, as it can have positive prognostic effect on natural course of disease process. The patient did receive dual anti-fungal drugs, along with Antiretroviral therapy (ARV) and showed drastic clinical improvement.

Published: November 2024

Snake bites pose a significant public health issue in Indonesia, leading to high morbidity and mortality rates. Proper identification of snake species and timely management are crucial. A 70-year-old woman was admitted to the emergency department 1.5 hours after being bitten by a snake. Initial management included applying a tourniquet and symptomatic treatment. However, local envenomation signs, such as edema and bullae, developed within 24 hours. Due to financial constraints, the patient could not receive continuous care, leading to complications, including necrosis and signs of secondary infection during follow-up. This case underscores the importance of early intervention and proper wound management in snake bites, particularly when the species is unidentified. Close monitoring is essential, as symptoms may evolve over time. Educating the patients and public regarding signs of necrosis and proper initial treatment is necessary. Effective management of snake bites requires a comprehensive approach, including prompt medical attention and ongoing education to reduce complications and improve patient outcomes.
