Abstract This study evaluated the effects of days-fasting followed by days-refeeding on growth, biochemical, and hepatic parameters in pacu (Piaractus mesopotamicus). One hundred and twenty juveniles P. mesopotamicus with initial average weight and length of 47.7 ± 9.2 g and 13.4 ± 0.9 cm were randomly distributed into six experimental units (20 fish per unit) and subjected to treatments: 30 days-fasting followed by 50 days-refeeding, and control group, fed continuously throughout the period. During the fasting period, samples were collected at 10, 20, and 30 days, while during the refeeding period at 15 and 50 days. Animals in the control group were sampled at the same periods. Weight (g), relative condition factor (Kn), and hepatosomatic index (biometric parameters) were measured. Liver assessments were performed. Additionally, glucose, plasma biochemical parameters levels were measured. After 30 days of fasting, hepatocyte density (73.8 ± 1.09%), liver glycogen (14.9 ± 0.87%) and hepatocyte nuclear volume (27.3 ± 0.30 µm3) were lower compared to the control group (82.0 ± 0.67%, 19.4 ± 0.74% and 43.40 ± 0.48 µm3 respectively). The relative condition factor remained unchanged. Cholesterol values, blood vessels, and sinusoidal density increased significantly during fasting. After refeeding, parameters were restored to the control level. On the 50th day of refeeding, the hepatosomatic index was significantly higher than the control group. The results showed that fasting associated with refeeding did not affect fish growth. The period over 50 days of refeeding may influence the pacu's compensation compared to daily-fed animals. The effects of fasting and its relationship with the pacu's physiological response through nutritional status become useful in contributing to feeding practices in P. mesopotamicus fish farming.

Abstract Cassava dregs are a byproduct of processing cassava into tapioca. These ingredients possess a simplified carbohydrate structure after fermentation, which also serves as an essential carbon source to support bacterial growth. This research aims to examine the utilization of cassava dregs ferment (CDF) in accelerating biofloc formation for intensive whiteleg shrimp (Penaeus vannamei) culture. The research was carried out over 60 days in two HDPE-lined ponds. Treatment A (with CDF) was stocked with 200 shrimp/m2. Treatment B (without CDF) was stocked with 300 shrimp/m2. Treatment A accelerated the formation of biofloc at DOC 26, whereas the biofloc formation in Treatment B started at DOC 38. Weight growth of shrimp was similar to Treatment A, averaging 6.21 ±1.27 g as compared to 6.21 ±1.73 g in Treatment B. Survival rates were significantly different, with 99.1% in Treatment A and 75.3% in Treatment B. Feed conversion ratio and total biomass were 1.4/1,153 kg (Treatment A) and 1.49/1,263 kg (Treatment B). Based on these findings, it appears that CDF can be used as an alternative source of exogenous carbon in biofloc technology and improve the productivity of intensive whiteleg shrimp culture.

Abstract The effectiveness of the anti-stress drug “Hydro Rex Vital” in the rearing of broiler chickens during the transitional period of the year was studied. The study was conducted on broiler chickens of the “Arbor Acres” crossbreed at the farm of “Altynbek” LLP (Almaty region, Isayev village). Four groups (one control and three experimental) were formed using the analogy method at the age of one day. The chickens of all groups were kept in the same room (identical sections) on deep litter until the age of 42 days. The drug was not used in the control group 1, while in the experimental groups 2, 3, and 4, the dosage of the drug administered with drinking water was 200, 300, and 400 ml per 1 ton of water, respectively. The results of the study showed that the survival rate in groups 1 (control), 2, 3, and 4 was 90.0%; 93.3%; 96.7%; 96.7% respectively; live weight of chickens at the age of 42 days was 2.49; 2.60; 2.65; and 2.57 kg respectively; average daily weight gain was 58.3; 60.8; 62.0; and 60.0 g respectively; feed consumption per 1 kg of live weight gain was 1.85; 1.74; 1.69; and 1.57 kg respectively; the slaughter yield of eviscerated carcasses was 72.2; 74.9; 76.3; and 74.0% respectively; production profitability was 170; 263; 313; and 308% respectively. It is recommended to give the anti-stress drug “Hydro Rex Vital” to broiler chickens with water at a dosage of 300 ml per 1 ton of water from the age of one day until the end of the rearing period to improve viability and productivity, reduce feed costs per unit of product, and meat production cost, and increase production profitability. In research, it is advisable to use the Russian production efficiency index instead of the European productivity index to quickly determine the winning group.

Abstract Naringenin is a flavonoid known for its anti-inflammatory, antineoplastic, antiatherogenic, and antioxidant properties. However, it has poor technological characteristics and limited bioavailability, which hinder its use in food applications. Nanoencapsulation could address these limitations, but safety concerns regarding nanoengineered bioactives need to be resolved before they can be effectively utilized as food additives. The objective of this study was to evaluate the potential cytotoxic, genotoxic, and mutagenic effects of both free and encapsulated naringenin through in vivo experiments using Allium cepa L. roots, along with pharmacokinetic and molecular docking analyses. The results showed that naringenin nanoparticles did not produce significant changes in the cell division index of meristematic cells in A. cepa roots. Additionally, no significant alterations in the mitotic spindle or chromosomal breaks were observed. Molecular docking studies indicated that naringenin effectively binds to the active site of the catalase enzyme (CAT) in a competitive manner, while it attaches to a site away from the active site of superoxide dismutase (SOD2), demonstrating a non-competitive interaction. ADMET property assessments suggested that naringenin exhibits relatively low toxicity and has favorable molecular characteristics for oral administration. In summary, this study supports the potential of naringenin, particularly in its nanoencapsulated form, as a safe and effective ingredient for functional foods, provided that safety concerns regarding nanoencapsulation are adequately addressed.

Published: January 2025

ABSTRACT This study aimed at establishing the ideal sample size for evaluating the maturation cycle in Coffea arabica, and investigating the errors associated with different sample sizes, in addition to verifying the possibility of using the clustering method to separate genotypes according to the maturation stage. Two experiments were analyzed: one with F2:3 progenies using visual maturation assessment through fruit counting, and another with cultivars using image processing for maturation assessment. To determine the ideal sample size for this trait, we used the estimation of the errors associated with maturation, using the bootstrap technique. Subsequently, the K-means algorithm was tested as an alternative for clustering genotypes into maturation classes. The application of the bootstrap technique in order to estimate the error associated with maturation revealed that the adoption of a 450-mL sample size resulted in an associated error of approximately 5%, indicating that it is an adequate size for character assessment. The implementation of K-means as a clustering tool offers a promising perspective for Arabica coffee plant breeding programs. A more comprehensive analysis, which not only assesses the proportion of ripe fruits, but also considers the distribution of different maturation stages, provides a more accurate understanding of the maturation process. This allows a more precise identification of genotypes with the most suitable performance for different growing conditions, as well as enabling adjustments in harvest management and post-harvest processing, optimizing coffee quality.
Considerações históricas e físicas sobre a aberraçãoda luz estelar
Authors: Coimbra-Araújo Carlos H. , Bergold Arthur W.B.
Published: January 2025

No presente artigo é introduzido, de forma didática e simplificada, o conceito de aberração da luz estelar em astronomia a partir de uma perspectiva histórica e física. As investigações sobre esse fenômeno, desde sua descoberta por James Bradley, abriram o caminho para uma compreensão mais profunda sobre o universo mas, principalmente, a respeito da natureza fundamental da própria luz. Do ponto de vista do contexto histórico em que se localizam as descobertas sobre a aberração da luz estelar desde Aristóteles, mas de forma muito mais intensa após o trabalho de Copérnico, os astrônomos dos séculos XVII e XVIII precisavam de evidências empíricas para confirmar o movimento orbital da Terra em torno do Sol. As observações de Bradley na tentativa de obter o deslocamento paralático das estrelas – a mudança na posição de uma estrela durante um período de seis meses – desempenharam um papel crucial nessa direção. De fato, nesse processo ele acabou por descobrir o fenômeno da aberração, um deslocamento anômalo da luz estelar que ele atribuiu à translação da Terra. Essa descoberta foi fundamental no processo histórico de descarte da ideia de que o Sol gira em torno da Terra (o sistema geocêntrico). No presente trabalho, após a contextualização histórica, apresentamos a conceituação qualitativa do fenômeno da aberração e aprofundamos seu entendimento a partir de uma perspectiva quantitativa.

Published: January 2025

Resumen El propósito de este estudio fue examinar el rol docente en la promoción de la inclusión del estudiantado LGTBIQ+ en las políticas educativas de algunos países de América Latina. Se realizó un diseño documental cualitativo, aplicando técnicas operacionales para el manejo de fuentes documentales. Los resultados indican que el sentido antidiscriminatorio y de promoción, accesibilidad y creación de ambientes respetuosos solo se encuentra en los marcos más recientes adoptados por algunos países de la región. Sobre el rol del profesorado, se incluyen vertientes de capacitación y sensibilización, lo cual no se ajusta completamente a la situación y no garantiza una enseñanza inclusiva. Se concluye que la política pública no converge con el papel del profesorado. Se establecen leyes que, en algunos casos, son generales y, en otros, específicas para la inclusión de este colectivo, pero con un sentido de ambivalencia.
RACISMO E REIVINDICAÇÃO DE RECONHECIMENTO NA EXPERIÊNCIA CURRICULAR
Authors: Chaves Silvane Lopes , Macedo Elizabeth
Published: January 2025

Resumo A partir da teoria pós-estrutural, problematizamos a distribuição tática da precariedade endereçada a pessoas pretas, diluída em políticas de Estado, em práticas institucionais e em relações intersubjetivas cotidianas. Em razão do caráter performativo da teoria, burilamos os diferentes modos de aparecimento da precariedade em algumas pesquisas, entendida como persistência de um traço do racismo. Argumentamos que a distribuição desigual do cuidado extrapola a dimensão material e vaza para os processos de subjetivação de crianças negras na experiência curricular. Diante da promessa de solução sempre adiada, trazem uma reivindicação que constrange as normas de reconhecimento, transitando para a exigência política de humanização, não apenas como gesto ético de cuidado, mas também de reparação.

Abstract The aim of this study was to evaluate the influence of diluent, stored volume and the cryodiluent medium supplementation with sulfated polysaccharides (SP) extracted from Nile tilapia skin on P. brevis vitrified sperm. Six pools were diluted in 5% Glucose or Powder Coconut Water (ACP-104), supplemented or not with 0.5 mg/mL of SP, and submitted to vitrification. Subsequently, they were stored in cryotubes in two volumes (60 μL and 420 μL). After 15 days, the samples were devitrified and evaluated for kinetics, membrane integrity and sperm DNA integrity. ACP-104 proved to be the best diluent for P. brevis sperm vitrification. Membrane and DNA integrity rates were higher (P < 0.05) when stored in smaller and larger volume, respectively. Additionally, the best rates (P < 0.05) of these same parameters were obtained with supplemented medium. There was interaction (P < 0.05) between diluent and stored volume, with ACP-104 exceeding 5% Glucose for motility in both volumes, while for average path speed (VAP) and membrane integrity the same happened in the larger volume. 5% Glucose had higher VAP and membrane integrity when stored in smaller volume. There was a triple interaction (P < 0.05) for DNA integrity, and better results were obtained when semen was vitrified in ACP-104 and stored in the larger volume, regardless of supplementation, which influenced only the 5% Glucose medium in the smaller volume. It was concluded that ACP-104, supplemented with SP and stored in larger volume make up the best treatment for P. brevis sperm vitrification.

Published: January 2025

ABSTRACT Objective: To investigate the influence of the parents’ attitude on the duration of the pacifier sucking habit and the occurrence of anterior open bite (AOB) in children. Material and Methods: A population-based cross-sectional study was conducted in Ribeirão das Neves, Brazil, including 497 children aged 4–6 years. The pacifier use was reported by the parents and categorized as "never used", "used up to 24 months" and "used more than 24 months". Perceived parental positive attitude was measured by two self-reported questions "I have enough energy to do what has to be done" and "I have self-discipline". Socioeconomic variables were collected. Children were examined by two examiners to the diagnosis of AOB according to Forster and Hamilton criteria. Adjusted logistic and multinomial regressions were performed (p<0.05). Results: Children who used pacifiers more than 24 months were 6.21 times more likely to have AOB than those who did not use pacifier (95% CL 2.98–12.92). Children who discontinued pacifier use within 24 months had parents with higher energy than those who keep the habit for more than 24 months (OR: 1.22; 95% CL 1.01–1.47). Parents from children who never used or used pacifier for less than 24 months were more self-disciplined than those who used for more than 24 months (OR 1.18; 95% CL 1.01–1.37; OR 1.29; 95% CL 1.06–1.56). Conclusion: High energy and self-discipline of parents were active factors in the discontinuation of pacifier sucking habit in less than 24 months.

Material and Methods: A retrospective cross-sectional study was performed on lateral cephalogram radiographs acquired from the University Dental Hospital. Through convenience sampling, 70 lateral cephalograms were selected from 200, meeting the inclusion criteria for this study. Study subjects were divided into three groups: Class I (n=2S), Class II (n=2l), and Class III (n=24). The study groups were compared based on the linear upper pharyngeal airway space measurements. Results: The three groups observed significant differences between the upper pharyngeal airway measurements. No differences in parameters were noted within the male and female study subjects. A highly significant difference (p<0.00l) in the Palatal Pharyngeal Distance was observed among the groups. Similarly, when the mean Middle Pharyngeal Distance and mean Inferior Pharyngeal Distance were compared among the three study groups, a highly significant difference (p<0.001 and p<0.004, respectively) was observed. Conclusion: The highest variation in the linear dimensions of the upper pharyngeal airway space among the different skeletal malocclusion was observed in the Nasopharynx, Skeletal Class III having the most prominent dimensions followed by Class I and the least in Class II skeletal malocclusion.

ABSTRACT Objective: To determine the clinical characteristics and treatment outcomes in patients with trigeminal neuralgia in a tertiary care setting. Material and Methods: The data of patients diagnosed with trigeminal neuralgia over a nine-year period in this tertiary care center from the archives of the Medical Records Department were included. Two observers documented the clinical data and treatment outcomes in a specially designed proforma. A p-value of <0.0S was considered statistically significant. A comparison of categorical variables was done using the Chi-square/Fisher exact test. A comparison of continuous variables was done using the Mann-Whitney U test. Results: There were 34 males and 24 females with a mean age of onset of neuralgia at S2.02 years. The estimated prevalence of trigeminal neuralgia from this tertiary care center in Karnataka, India, is 0.007%. There was a female dominance regarding the reported symptoms that triggered pain (p=0.031), with talking and chewing being the most common triggers. Primary and classical variants were the most common types. Medical management was the sole treatment of choice for nine participants; surgery was performed for 49 and 14 participants underwent a combination therapy. Conclusion: No single best treatment option has been established for this disorder. Further clinical trials with promising pain management regimens need to be conducted to strengthen the existing evidence for improving the quality of life of these individuals.

Resumo Este estudo realizou uma revisão descritiva e exploratória da literatura com o objetivo de descrever como a disponibilidade, o acesso e o consumo de alimentos são permeados e relacionados a questões de gênero. A partir de uma pesquisa em bases de dados e de busca manual, foram encontrados 833 resumos, dos quais foram selecionados 37 textos completos com base nos critérios de inclusão. Os resultados mostram que há acentuadas diferenças de gênero em diferentes dimensões da segurança alimentar. As mulheres estão particularmente suscetíveis à insegurança alimentar, sendo os domicílios chefiados por mulheres os mais expostos a essa condição (n=4). Entre as mulheres em insegurança alimentar há maior prevalência de obesidade quando comparadas àquelas com segurança alimentar (n=8). Por sua vez, os estudos indicam que na alimentação as mulheres subordinam suas próprias necessidades a de seus filhos e parceiros (n=5). Em relação ao acesso aos alimentos consumidos no domicílio, os estudos corroboram a importância do papel das mulheres (n=3). As diferenças de género identificadas mostram a pertinência de abordagem e análise das questões relacionadas à alimentação e nutrição em diferentes contextos, bem como a formulação e implementação de políticas e intervenções de saúde pública.
Cartografía del pensamiento crítico: principales aportaciones para repensar la educación
Authors: Vendrell-Morancho Mireia , Moya Aída Valero
Published: January 2025

Resumen El pensamiento crítico es una herramienta esencial para la evaluación racional y ética de la información y las acciones. Por lo tanto, es un elemento clave para tomar decisiones informadas y participar en el diálogo y el debate democráticos. Aunque su importancia es ampliamente reconocida, existe una falta de consenso en cuanto a su definición y enfoque. Al mismo tiempo, la investigación sobre su historia y desarrollo filosófico es limitada. El objetivo del presente estudio es examinar la evolución histórico-filosófica del pensamiento crítico, rescatando sus principales aportaciones desde Sócrates hasta el Informe Delphi de Peter Facione. Con el fin de facilitar su estudio y comprensión, dicha evolución se ha dividido en las siguientes etapas: Edad Antigua, Edad Media, Renacimiento y Edad Moderna, y Edad Contemporánea. Tal división se basa en los hitos importantes y los cambios históricos que tuvieron lugar en cada una de las épocas. Los resultados muestran que el pensamiento crítico es un concepto que ha evolucionado a lo largo del tiempo y que ha sido influenciado por diferentes factores históricos, culturales y sociales. En particular, lo que en la actualidad entendemos por pensamiento crítico está altamente influenciado por el racionalismo, empirismo, positivismo y pragmatismo de la tradición occidental. Esta contribución es relevante a la hora de repensar la investigación y la praxis educativa, ya que permite una comprensión más profunda del pensamiento crítico y de su aplicación.

Published: January 2025

Abstract The Covid-19 pandemic forced universities to shift to an online learning modality and to dispense with face-to-face education, highlighting the inequality of opportunities and fewer education options in some sectors of the population. Students from rural areas had the greatest difficulties due to the possible lack of access to technological means and the quality of their internet connections. The present article is a systematic review of the literature about rurality and the use of technology in the university setting during Covid-19, through the analysis of 105 articles extracted from the Web of Science and Scopus, which were screened following the PRISMA guidelines, for a total of 17 valid articles. The results describe the university policies developed, the technologies utilized, the difficulties, and the good practices conceived. It is possible to conclude that the challenges experienced by rural students were greater than urban students, and being aware of this, the university policies worldwide opted for ensuring financial resources that could serve as support to these more vulnerable student sectors, so that they could follow the online classes. There is still much to be done, and it is necessary to adapt higher education to the specificities of rural areas and online education, to achieve a greater equality of opportunities.

Authors: Araújo Lucas , Azeredo Givanildo
Published: January 2025

Resumo A terra como material de construção vem voltando ao foco da comunidade científica devido à sua baixa energia incorporada. Existem poucos estudos sobre matrizes de terra autoadensáveis como técnica construtiva. Dessa forma, o presente estudo tem como objetivo desenvolver um compósito de terra autoadensável estabilizado com ativação alcalina para construção de paredes monolíticas e avaliação do seu comportamento mecânico. Após um estudo de dosagem por planejamento fatorial, foi selecionada a melhor composição de terra, areia, metacaulim e solução ativadora para melhor avaliação do compósito e construção da parede. Com a mistura selecionada, foram realizados ensaios de caracterização física, difração de raios X (DRX), espectroscopia de infravermelho, funil V, resistência à compressão e à tração na flexão, além da construção de uma parede reduzida. A resistência à compressão do compósito foi de 8,12 MPa aos 3 dias e 9,75 MPa aos 28 dias. A parede apresentou fissuras de retração, que não influenciaram diretamente na sua ruptura, e atingiu uma tensão de 3,30 MPa. Por fim, o compósito apresentou um bom comportamento reológico tanto no estado fresco quanto no estado endurecido podendo ser utilizado na construção de paredes monolíticas.

Resumo Sistemas de telhados verdes são práticas sustentáveis para reduzir efeitos adversos da urbanização em áreas densas, pois mitigam ilhas de calor urbano, retém águas pluviais e reduzem seu pico de fluxo e escoamento, melhoram a qualidade do ar urbano, absorvem emissões sonoras, aumentam a eficiência térmica e proporcionam um efeito estético agradável. Países como Alemanha, França, China, EUA, Canadá e Japão incentivam a instalação da tecnologia em novas edificações ou pela adaptação de edificações existentes. Contudo, seu uso é pouco difundido em muitos países e regiões em desenvolvimento, como no Brasil. Esta pesquisa visa, por meio de revisão de literatura internacional, analisar as causas que podem dificultar a adoção dos telhados verdes e assim subsidiar a discussão sobre sua aplicação em edificações brasileiras, a partir das experiências observadas em outros países. A pesquisa utilizou parte da metodologia Proknow-C e revelou 19 grandes obstáculos à implantação de telhados verdes, divididos em 4 grupos: (1) barreiras ligadas a aspectos técnicos; de (2) natureza econômica; (3) alusivas à pouca disseminação de conhecimento sobre o assunto e (4) ligadas à abordagem ambiental.

Resumo O uso de drones e visão computacional aumenta a eficiência nas inspeções de segurança em obras. No entanto, há uma lacuna na aplicação integrada dessas tecnologias em inspeções de sistemas de guarda-corpos e rodapés (GcR). Este artigo visa desenvolver um sistema de detecção de GcR para obras utilizando drones e visão computacional. A pesquisa incluiu a definição e validação de protocolo de coleta de imagens com drone, coleta de imagens em duas obras, e treinamento e teste de quatro modelos de detecção de objetos em um sistema de visão computacional usando imagens originais e artificiais (com zoom, rotação e cisalhamento). A detecção automatizada de GcR apresentou elevado desempenho, com precisão de 96,83% e 95,31% na etapa de teste para os modelos treinados com imagens com cisalhamento e rotação, respectivamente. Esta pesquisa contribuiu com o avanço da integração de drones e visão computacional para inspeções automatizadas de GcR em obras, permitindo maior eficiência e agilidade na coleta, processamento e análise dos resultados.

Abstract The application of recycled sand from construction and demolition waste (CDW) in the soil-cement mixture for the manufacture of modular bricks for structural masonry was investigated, evaluating bricks and prisms. Firstly, the optimum moisture content was analyzed by analyzing the additions of CDW with 20%, 40%, 50% and 60%, by mass, in the soil mixture with 10% cement. The bricks were evaluated for their geometric characteristics, compressive strength, density and water absorption. The compressive strength of the bricks was analyzed at different ages (7, 14, 28, 56 and 530 days). The prisms (250.75mm x 126.41 mm x 137.16 mm), with a conventional 5 mm mortar joint, were evaluated for compressive strength, modulus of elasticity and failure mode, aged 530 days. The results demonstrated the feasibility of using CDW, which increases the compressive strength of the bricks, but makes molding difficult, as it reduces initial cohesion. The efficiency factor of the prisms was 57%. The failure mode observed was tension in the bricks and subsequent propagation of cracks in the joints - behavior similar to materials with brittle rupture. Brazilian standards approached the mechanical behavior of the material.

Abstract :Information and communication technology (ICT) tools have been widely used in teaching and learning during the past two decades. ICT tools enhance, support, and optimize the delivery of information. ICT tools improve teaching methods and enhance effective student learning. During the COVID-19 pandemic period, online teachinglearning methods helped teachers and students carry out teaching-learning effectively while following the guidelines prescribed by the health department for preventing the spread of the disease. The recently implemented competency-based medical education system (CMBE) in India uses e-learning as a key tool for self-directed learning. The National Medical Commission (NMC), the leading organisation in charge of medical education in India, has acknowledged the value of online learning. Many online collaboration tools for students, as well as teaching tools for teachers, are described in this paper. Innovative online learning methods are illustrated with schematic graphics showing their inter-relations. Multiple approaches to effective learning are discussed in detail. The challenges experienced by teachers and students during online teaching andlearning are presented. It is shown that the innovative use of open educational resources (OER), massive open online courses (MOOC), and YouTube videos by teachers and students produce synergy in the online teaching-learning process. The way forward in the post-pandemic era and case studies from various higher education institutes in India are discussed.
