Психологическая структура образа физического «Я» женщин, занимающихся «мягкими техниками» фитнеса
Authors: Лужбина Наталья , Чернышова Ольга 
Published: July 2023

Данная работа была направлена на исследование структуры и компонентов образа физического «Я» женщин возраста средней зрелости (по классификации Э. Эриксона) в контексте занятий осознанными «мягкими техниками» фитнеса (пилатес, йога, бодифлекс, стретчинг, миофасциальный релиз и их сочетания). В качестве психодиагностического инструментария для исследования структуры и компонентов образа физического «Я» был использован опросник В.А. Лабунской «Оценочно-содержательная интерпретация компонентов внешнего облика». Методами математико-статистической обработки данных стали непараметрический критерий U Манна-Уитни и факторный анализ. В исследовании принимали участие две группы женщин в возрасте от 30 до 60 лет (занимающиеся и не занимающиеся осознанными техниками фитнеса). В результате исследования удалось выявить, что занятия «мягкими техниками» фитнеса формируют новую структуру образа физического «Я» занимающихся женщин, связанную с оценками телосложения и оформления внешнего облика, а также с характеристиками женственности лица и поведения.
SISTEMAS ATMOSFÉRICOS ASSOCIADOS AOS TIPOS DE TEMPO DURANTE ANOS MUITO SECOS E MUITO CHUVOSOS NO MUNICÍPIO DE SÃO GONÇALO-RJ
Authors: Tórnio Carlos Augusto Abreu , Kede Maria Luiza Félix Marques 
Published: July 2023

RESUMO: O objetivo deste trabalho é caracterizar o comportamento da precipitação pluvial no município de São Gonçalo-RJ, entre os anos de 2005 e 2018, identificando os anos considerados muito secos e muito chuvosos, e verificar os sistemas atmosféricos que se associam aos tipos de tempo observados. Para isso, a metodologia se baseou na classificação do comportamento da precipitação pela técnica dos quantis. Após isso, foi realizada a análise rítmica dos tipos de tempo dos meses correspondentes ao período chuvoso dos anos muito secos e muito chuvosos. A partir da técnica dos quantis, foram classificados como anos muito secos, aqueles cujo total anual for inferior a 897,77 mm (2007 e 2014), e como muito chuvosos, aqueles cujo total superou os 1284 mm (2008 e 2010). Nos anos muito chuvosos predominou a atuação de sistemas de baixa pressão como a mEc, formação de cavados, passagem de sistemas frontais e formação de ZCAS, fundamentais à manutenção das chuvas no Sudeste do Brasil. Já nos anos muito secos, esses fenômenos tiveram suas participações inibidas pelas influências da mPa vinda de Sul, e da mTa acoplada a ASAS, que agia com frequência pela costa leste.

A Metaheuristic Approach to Parameter Estimation of a Flexible Parametric Mixture Cure Rate Model with Interval-Censored Data
Authors: Borges P. , Campos M. 
Published: July 2023

A flexible parametric mixture cure model, called bi-lognormal cure rate model or simply BLN model, is defined and studied. The BLN model can be effectively used to analyze survival dataset in the presence of long-term survivors, especially when the dataset presents the underlying phenomenon of latent competing risks or when there is evidence that a bimodal hazard function is appropriated to described it, which are advantages over other cure rate models found in the literature. We discuss the maximum likelihood estimation for the model parameters considering interval-censored data through the differential evolution algorithm that is a nature-inspired computing metaheuristic used for global optimization of functions defined in multidimensional spaces. This approach is also used because the likelihood function of the model is multimodal and the direct application of gradient methods in this case is not ideal, since such methods are local search methods with a high chance of getting stuck at a local maximum when the starting point is chosen outside the basin of attraction of a global maximum. In addition, a simulation study was implemented to compare the performance of differential evolution algorithm with the performance of the Newton-Raphson algorithm in terms of bias, root mean square error, and the coverage probability of the asymptotic confidence intervals for the parameters. Finally, an application of the BLN model to real data is presented to illustrate that it can provide a better fit than other mixture cure rate models.

Published: July 2023

As braquiárias (Urochloa spp.) tem sido muito utilizada na pecuária e na agricultura brasileira, como plantas forrageiras e de cobertura de solo. Assim, o objetivo do presente estudo foi avaliar no ambiente edafoclimático de Coruripe, região leste do estado de Alagoas, a produção e a qualidade bromatológica das braquiárias brizantha e decumbens, bem como o potencial produtivo destas plantas como recobridoras do solo e recicladoras de nutrientes. O solo utilizado foi um Latossolo Vermelho-Amarelo distrófico, de textura média, tendo saturação por bases de 47% na camada de 0 a 20 cm, teor médio de fósforo e alto de potássio. A semeadura das braquiárias foi realizada em abril, logo após o início das chuvas. O delineamento experimental foi o de blocos ao acaso, com cinco repetições, sendo as parcelas constituídas de cinco sulcos de cinco metros de comprimento, espaçados de 0,60 metros. No fundo do sulco aberto para a semeadura foi aplicado fósforo, na dose equivalente a 50 kg de P ha-1 (equivalente a 114,5 kg de P2O5) usando o superfosfato simples com fonte de P. As adubações nitrogenada e potássica foram realizadas em cobertura, quando as plantas apresentaram cerca de 5 cm de altura. As adubações de cobertura foram em doses equivalentes a 150 ha-1, usando o sulfato de amônio e cloreto de potássio como fontes de nutrientes. As avaliações da produção e a qualidade bromatológica das braquiárias foram realizadas aos 45 dias após a emergência das plantas (D.A.E), quando as plantas apresentavam cerca de 90 a 95% de interceptação luminosa. Na avaliação do potencial de acúmulo de matéria seca e reciclador de nutrientes, as avaliações foram aos 105 D.A.E. As braquiárias brizantha e decumbens tiveram alta taxa de crescimento, mas na avaliação realizada 45 D.A.E, a braquiária decumbens teve acúmulo de matéria seca em toda a parte aérea 25% maior que a braquiária brizantha, alcançando 6,28 t de matéria seca por hectare. Quanto a concentração de nutrientes na forragem, as braquiárias tiveram a mesma concentração de proteína bruta, fósforo e magnésio. Para o cálcio, os teores na parte aérea da braquiária brizantha foram maiores que os da braquiária decumbens, ocorrendo o contrário quanto à concentração de enxofre. Na avaliação realizada aos 105 D.A.E., como plantas de cobertura de solo e recicladoras de nutrientes, as braquiárias tiveram alta produtividade, contudo o acúmulo médio de matéria seca e a ciclagem de nitrogênio, fósforo e potássio pela braquiária brizantha superou os da braquiária decumbens. Por outro lado, não houve diferença significativa entre as braquiárias quanto ao acúmulo de cálcio, magnésio e enxofre.

Published: July 2023

Mindfulness has gained significant attention in recent years due to its potential benefits for
cognitive and emotional processes. However, how mindfulness interplays with affect to exert its
effect on decision-making remains relatively less explored. The present study examined and
compared the performance of both mindfulness meditators and non-meditators on decisionmaking
tasks under different affective states. A total of 100 participants (50 mindfulness meditators
and 50 non-meditators) responded to the Five Facet Mindfulness Questionnaire (FFMQ) and
performed the Iowa Gambling Task (IGT). Both groups were further divided into positive affect
and negative affect conditions. The International Affective Picture System (IAPS) was used to
induce positive and negative affective states among the participants. The baseline affective state
of the participants was assessed using the Positive and Negative Affect Schedule (PANAS).
Independent sample t-tests and a univariate ANOVA were computed to analyze the obtained
data. Results showed that mindfulness meditators scored significantly higher on the total FFMQ
as well as on its different facets. Furthermore, the results revealed a significant main effect of
mindfulness and the affect group on IGT performance. The interaction between mindfulness and
affective conditions was also found to be significant. Mindfulness meditators performed equally
well on IGT under both positive and negative affect conditions, whereas non-meditators
performed better only under positive affect conditions. The findings have practical implications,
as they suggest that mindfulness meditation enhances decision-making by promoting effective
emotion regulation and suppressing impulsive responses during decision-making in different
domains of life.

Published: July 2023

Thaparocleidus wallagonius is a monogenean parasite and a fish-borne pathogen with a worldwide distribution. The present study focuses on in silico analysis of 18S rDNA of Thaparocleidus wallagonius collected from the fish Wallago attu from India. 18S rDNA serves as the source of taxonomic, standard reference sequences and systematic markers. The objective of genomics is the quantification, the collective characterization of the genes present in an organism, their influence, and interrelations on the organism. In this study, we designed 10 primers of the 18S rDNA sequence. 18S rRNA genes may be more useful in identifying the most efficient rRNA genes for genetic engineering and in understanding the relationship of the parasite with its host. The discovery of these primers will aid drug design studies, which could be a valuable tool for improving health of animal.

The main barrier to livestock production in Ethiopia is an insufficient supply of feed, both in terms of quantity and quality. This study was conducted in the Doyogena district of the Kembata-Tembaro zone of Southern Ethiopia with the objectives of determining the availability and nutritive value of major livestock feeds; conserving and utilizing available feed resources. The utilization practices of different feeds was assessed with a self-structured questionnaires. Chemical composition of major feed resources was estimated in animal nutrition lab of Hawassa University. Natural pasture and crop leftovers are key feed resources in the area and cultivated forages were only lately introduced, with limited adoption due to agricultural land scarcity. Their use for livestock feed had been hindered by economic, inadequate handling and processing problems. The involvement of the government for improving the financial capabilities of farmers with improved technologies related to feeding crop residues and natural pastures were suggested as an important strategy. Chemical analysis on major feed resources indicated that there were significant (p<0.05) difference among the feed types in CP and NDF content. The CP varied from 5.37% to 79.24% in woynadega while in kola it ranged from 4.54% to 79.41%. In the woynadega agroecology, the NDF content ranged from 44.17% to 79.24%, whereas in kola, it ranged from 44.13 % to 79.41 %. ADF and lignin contents were also significantly different (P<0.05). The ADF and lignin contents ranged from 12.86% to 48.91%and 3.57% to 9.70% respectively in woynadega, in kola agroecology ranged from 12.74% to 50.04% and 3.52% to 10.49% respectively. There were significant differences in IVDMD (p<0.05%) also, and it ranged from 47.30% to 79.78% in woynadega agro-ecology and in kola it ranged from 59.98% to 79.67%. As a result, farmers must learn how to use and process locally available feeds in order to improve local animal production performance.
GROWTH PERFORMANCE, CARCASS YIELD AND HAEMATOLOGICAL RESPONSE OF BROILER CHICKENS FED ON PROCESSED HARICOT BEAN (Phaseolus vulagris L.)
Authors: HEMACHA SELAMU ABRAHAM , LOMBEBO WONDIMU AYELE 
Published: July 2023

Background: Haricot bean is among the most important legumes grain in Ethiopia. The beans are good sources of protein, carbohydrates and mineral nutrients required for normal functioning of the body. Despite of its nutritional quality, it is poor digestible due to anti-nutritional factors present in the bean.
Methods: A total of 168 Sasso strain broiler chickens were used with an initial body weight of 39.65±2.15g for the trial. The chicks were randomly allotted into four treatments with 14 birds per replication. Haricot bean was soaked in water for five hours at ratio of 1 kilogram to 5 liters, and then cooked for an hour to reduce anti-nutritional factors. The treatment diets have contained the bean at proportion of 0, 10, 20 and 30% for T1, T2, T3 and T4, respectively.
Results: T3 and T4 gave best performance (P≤0.05) in final body weight, slaughter weight, dressed carcass and eviscerated weight. A significant (P≤0.05) increase were observed in white blood cell, red blood cell, haemoglobin and packed cell volume with increasing the rate of processed haricot bean in the treatment diets..
Conclusions: Therefore, an amalgamation of processed haricot beans in the broiler ration showed an optimistic result in the overall performance and immunity of broiler chickens.
