The management of thermal environments in animal production facilities presents significant challenges, requiring continuous adjustments to meet animals’ physiological needs. This study evaluated the effects green roofs on environment and comfort indices small-scale poultry house prototypes, comparing with without roof installations. research tested various types (ceramic, fiber cement, metal) combined emerald grass (Zoysia japonica) systems. Parameters measured included air temperature,...
Two field experiments (Exp. 1 and Exp. 2) were carried out to assess the physiological performance grain yield of wheat cultivars BR‐18 (moderately resistant) Guamirim (susceptible) inoculated with Pyricularia oryzae in plots treated or untreated Ópera (fungicide 13.3% epoxiconazole + 5% pyraclostrobin). Results from regression analyses indicated that spike leaf blast severity at 10–14 days after inoculation (dai) associated greater losses (highest negative slope) than 18–22 dai. Relative...
As doses e a época de aplicação do nitrogênio (N) podem influenciar as características agronômicas trigo (Triticum aestivum L.) irrigado e, conseqüentemente, produtividade grãos. Neste sentido, foram instalados dois experimentos na Estação Experimental da Universidade Federal Viçosa, localizada em Coimbra (MG), 1995 1996. Os tratamentos constituídos pela combinação quatro N (30, 60, 90 120 kg ha-1), formas parcelamento (dose total aos 20 dias emergência (DAE); ½ + 40 DAE; 1/3 2/3 DAE DAE)...
The development of heat-tolerant varieties is an important goal wheat breeding programs, requiring efficient selection methods. In the present study use recurrent was evaluated as a strategy to improve heat stress tolerance in wheat. Two cycles were performed experiments conducted research areas Universidade Federal de Vicosa, located Coimbra-MG and Vicosa-MG, 2004 2007, two growing seasons (summer winter). genetic gain existence variability show possibility successful for heat-
Autosomal dominant polycystic kidney disease (ADPKD) is a hereditary nephropathy characterized by abnormal growth of epithelial cells.Genetic factors, including the vascular endothelial factor (VEGF) gene, play an important role in its progression.The main aim this study was to evaluate influence VEGF-C936T polymorphism development and progression ADPKD.In total, 302 individuals were studied divided into two groups: G1 (73 patients with ADPKD) G2 (229 without disease).Among patients, 46...
O presente estudo objetiva analisar a literatura relacionada à sustentabilidade na agricultura familiar e aplicação em políticas públicas brasileiras. Para isso, foi realizada uma análise de artigos relacionados ao tema, destacando-se os principais tópicos, além dados secundários do Governo Federal. Por meio das informações coletadas, observou-se existência voltadas para alimentação (escolar da população) comercialização, evidenciando-se canais institucionais o escoamento dos alimentos...
OBJETIVO: averiguar as alterações induzidas pela quimioterapia primária no fenótipo celular. MÉTODOS: avaliamos a expressão do antígeno nuclear de proliferação celular (PCNA) e dos receptores estrogênio (RE) progesterona (RP) em 17 tumores mama estádio clínico II, obtidos antes após terapia antiblástica, por método imuno-histoquímico. Os valores foram relacionados com o estado menstrual, resposta clínica tumoral comprometimento axilar. RESULTADOS: houve redução significante na porcentagem...
Computer simulation can provide reliable information about fluid flow behavior, including ventilation, in animal production systems. The ventilation system is essential for thermal conditioning, as it favors comfort and enhance productivity. objective of this study was to develop validate a CFD (Computational Fluid Dynamics) model analyze the compost barn. A mesh with greater refinement used near air inlet outlet floor, that is, these regions number cells larger, which makes denser mesh. For...
