Adaptabilidade e estabilidade de genótipos de feijão-caupi em Mato Grosso do Sul.

O objetivo do trabalho foi avaliar a adaptabilidade e a estabilidade da produtividade de grãos de linhagens e cultivares de feijão-caupi para fins de recomendação para o Estado de Mato Grosso do Sul. Foram conduzidos quatro experimentos no período de fevereiro a junho de 2008 e 2009, em três municípios: Aquidauana, Chapadão do Sul e Dourados, localizados no Estado de Mato Grosso do Sul. O delineamento experimental foi o de blocos ao acaso, com 20 tratamentos e quatro repetições, em parcelas de quatro linhas de cinco metros. A adaptabilidade e estabilidade dos genótipos foi analisada pelo método do melhor desempenho. As linhagens MNCO2-675-4-9 e MNCO3-736F-6 apresentaram maior adaptabilidade e estabilidade, sendo as mais indicadas para cultivo em ambientes com maior grau de tecnologia. A linhagem MNCO2-689F-2-8 e a cultivar BRS Gurguéia podem ser recomendadas para os agricultores que utilizam pouca tecnologia no Estado de Mato Grosso do Sul.CONAC 2012.

This study investigate the pontentially detrimental effects of CO2 and its combination with copper on pacu

Shoulder isokinetic profile of male handball players of the Brazilian National Team

BACKGROUND:Data obtained on an isokinetic dynamometer are useful to characterize muscle status and have been reported in muscle imbalance studies in different types of sport. However, few studies have assessed elite handball players to establish reference values.OBJECTIVE:The purpose of this study was to compare, for the dominant (D) and non-dominant (ND) side, the isokinetic profile of shoulder rotator muscle strength between male handball players (H) and asymptomatic non-athletes (NA).METHOD:Isokinetic concentric and eccentric strength tests for D upper limbs were performed by the H group (n=20) and the NA group (n=12). Internal and external rotator muscle peak torque in concentric action was assessed at 60°/s and 300°/s and in eccentric action at 300°/s. We also calculated conventional balance (the ratio of external rotator peak torque to internal rotator peak torque in concentric action) and functional balance (the ratio of external rotator peak torque in eccentric action to internal rotator peak torque in concentric action).RESULTS:In the H group, dominant limbs were stronger in concentric action for external rotation at 60 and 300°/s. The conventional balance ratio for the D side was significantly lower at 60 and 300°/s for H compared to NA. The functional ratio for the D side was significantly lower at 300º/s for H compared to NA.CONCLUSIONS:Compared to asymptomatic non-athletes, handball players presented significant muscular imbalance resulting from daily sports practice, a known risk factor for shoulder injuries.Projects Finance Organization (Financiadora de Estudos e Projetos - FINEP)Universidade Federal de São Paulo (UNIFESP) Physiology DepartmentUniversidade Federal de Goias Human and Exercise Physiology SectorUniversidade Estadual de Campinas Faculty of Physical Education Sports Science DepartmentBrazilian Basketball ConfederationUNIFESP, Physiology DepartmentSciEL

Severity of Ascites Is Associated with Increased Mortality in Patients with Cirrhosis Secondary to Biliary Atresia

Very few prior studies have investigated the presence of ascites as a prognostic factor in children with cirrhosis. To the best of our knowledge, there are no prior studies evaluating the relationship between severity of ascites and patient survival in children with biliary atresia and cirrhosis.Clinically detectable ascites is associated with decreased 1-year survival of children with biliary atresia. These patients should be treated with caution and prioritized for liver transplantation.Background Very few prior studies have investigated the presence of ascites as a prognostic factor in children with cirrhosis. To the best of our knowledge, there are no prior studies evaluating the relationship between severity of ascites and patient survival in children with biliary atresia and cirrhosis. Aims To evaluate the association between severity of ascites and survival of children with cirrhosis and biliary atresia. Methods All children with cirrhosis secondary to biliary atresia evaluated at our institution from 2000 to 2014 were included in this study. Patients were classified into four groups: NA = no ascites; A1 = grade 1 ascites; A2 = grade 2 ascites; and A3 = grade 3 ascites. The primary endpoint of the study was mortality within the first year after patient inclusion. Ninetyday mortality was also evaluated. Prognostic factors related to both endpoints also were studied.

Stocking density and copper effects on the antioxidant defenses and hematological paramenters of pacu.

In this study the objectives were to determine the acute toxicity of copper in pacu and the influence of fish stocking densities to copper toxicity

Rendimento e composição centesimal do tambaqui (Colossoma macropomum) por diferentes cortes e categorias de peso.

O processamento industrial do tambaqui necessita melhor padronização de cortes para maior valorização no atual mercado consumidor. Isso inclui, também, o conhecimento da sua composição centesimal por categoria de peso. O objetivo desse estudo foi analisar o rendimento e a composição bromatológica do lombo e da costela de tambaquis em três categorias de peso vivo destinados ao abate comercial. Um total de 48 exemplares foi utilizado para avaliação dos rendimentos de filé, carcaça, vísceras e cabeças. Os filés foram separados em lombo e costela para as avaliações dos teores de umidade, proteína, lipídeos totais e matéria mineral. Os resultados demonstraram que tambaquis com menor peso vivo apresentaram menor rendimento de vísceras e maior rendimento de filé (p<0,05). Os dados de composição centesimal evidenciaram aumento do teor de lipídeos totais no lombo dos animais com peso acima de 2.000 g. Além disso, foi observado maior conteúdo de matéria mineral nas amostras de lombo de peixes com peso inferior a 500 g, possivelmente pela existência de espinhas intramusculares nas amostras analisadas. O estudo demonstrou diferenças de rendimento e de composição nutricional que devem ser consideradas pela indústria processadora para melhor adequar a estratégia de comercialização e valorização da espécie

Multi-Channel Auto-Calibration for the Atmospheric Imaging Assembly using Machine Learning

Solar activity plays a quintessential role in influencing the interplanetary medium and space-weather around the Earth. Remote sensing instruments onboard heliophysics space missions provide a pool of information about the Sun's activity via the measurement of its magnetic field and the emission of light from the multi-layered, multi-thermal, and dynamic solar atmosphere. Extreme UV (EUV) wavelength observations from space help in understanding the subtleties of the outer layers of the Sun, namely the chromosphere and the corona. Unfortunately, such instruments, like the Atmospheric Imaging Assembly (AIA) onboard NASA's Solar Dynamics Observatory (SDO), suffer from time-dependent degradation, reducing their sensitivity. Current state-of-the-art calibration techniques rely on periodic sounding rockets, which can be infrequent and rather unfeasible for deep-space missions. We present an alternative calibration approach based on convolutional neural networks (CNNs). We use SDO-AIA data for our analysis. Our results show that CNN-based models could comprehensively reproduce the sounding rocket experiments' outcomes within a reasonable degree of accuracy, indicating that it performs equally well compared with the current techniques. Furthermore, a comparison with a standard "astronomer's technique" baseline model reveals that the CNN approach significantly outperforms this baseline. Our approach establishes the framework for a novel technique to calibrate EUV instruments and advance our understanding of the cross-channel relation between different EUV channels.Comment: 12 pages, 7 figures, 8 tables.
