Objetivou-se, com este trabalho, estudar o efeito de diferentes lâminas de irrigação e doses de nitrogênio sobre as características agronômicas do feijão caupi inoculado. O experimento foi montado em parcelas subdivididas, tendo nas parcelas os níveis de nitrogênio e, nas subparcelas, as lâminas de irrigação, no delineamento em blocos ao acaso, com duas repetições. As lâminas de irrigação corresponderam a 578 mm (L1), 512 mm (L2), 429 mm (L3), 299 mm (L4) e 240 mm (L5) e, os níveis de nitrogênio, a 0, 30, 60 e 90 kg ha-1 de N. Os níveis de nitrogênio apresentaram respostas significativas nos componentes de produção de feijão caupi. As lâminas de irrigação proporcionaram efeitos significativos na produtividade do feijão caupi, sendo a lâmina de 426,21 mm a estimada para obtenção da produtividade máxima de 2820,03 kg ha-1.
There are several kinds of information that can be achieved in ancient documents. In general, image processing research on this subject works with images of letters or documents. Topographic maps and floor plans are also an important source of information about history. In this paper, we introduce a new algorithm for image segmentation of ancient maps and floor plans. It aims to remove most part of non textual elements leaving just the text. This allows further automatic identification of the map or plan through automatic character recognition techniques. The proposed method uses a new edge detection algorithm, thresholding and connected component analysis. The results are analyzed both qualitatively and quantitatively by comparison with other technique.
This study aimed to determine heights of water levels in the evaporimeter of the Irrigameter to directly obtain the evapotranspiration of the crop (ETc) in several stages of its growth. Moreover, evaluate the performance of the Irrigameter at managing irrigation in the bean cowpea crop. The study was conducted in the Campus of the State University of
RESUMOO Irrigâmetro é um aparelho evapopluviométrico a ser utilizado no manejo da irrigação, visando otimizar o uso de água. Contudo, o seu uso está condicionado a um ajuste prévio para as condições climáticas onde o mesmo será utilizado. Diante dessa premissa, objetivou-se neste trabalho,identificar a altura do nível de água no interior do evaporatório do Irrigâmetro para estimativa direta da evapotranspiração de referência nas condições climáticas do planalto de Vitória da Conquista -BA, para diferentes estações do ano. O experimento foi montado num delineamento inteiramente casualizado, com cinco tratamentos e três repetições. Para cada tratamento foi determinado um coeficiente médio para o Irrigâmetro, denominado K I , calculado pela relação entre a evapotranspiração estimada no Irrigâmetro (ET I ) e a evapotranspiração de referência (ET 0 ). A ET 0 foi obtida pelo método de Penman-Monteith -FAO 56. Os resultados permitiram concluir que os coeficientes do Irrigâmetro aumentaram exponencialmente com o aumento do nível da água dentro do evaporatório, e ainda que, o aparelho deve ser operado com o nível da água igual a 5,2 cm para melhor estimativa da ET 0 . As demais alturas observadas nas diferentes estações do ano não apresentaram diferença significativa quando comparadas a média anual adotada como referência neste estudo. Palavras-chave: ABSTRACTThe Irrigameter is aevapotranspiration measuring device used in irrigation management to optimize water. However, its use requires a prior adjustment to weather conditions where it will be used. The objective of this study was identify the corresponding height of water level inside the evaporimeterIrrigameter that estimate reference evapotranspiration in climate of the plateau of Vitoria da Conquista -BA, in different seasons. The experiment was a completely randomized design with five treatments and three replications. For each treatment was determined an average coefficient for the Irrigameter called K I , calculated as the ratio of estimated evapotranspiration in Irrigameter (ET I ) and reference evapotranspiration (ET 0 ).

Lifestyle changes have an impact on lipid metabolism. The overload of circulating lipids may lead to endothelial dysfunction, oxidative stress and exaggerated inflammatory response, which may be further aggravated in the presence of overweight. This study aims to describe the postprandial metabolism and inflammatory response in overweight and normal-weight adolescents. Sixty-two adolescents aged 11-18 years were divided into two groups: overweight (OW; n=38) and normal weight (NW; n=24). Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), glucose, insulin, high-sensitivity C-reactive protein (hs-CRP), fibrinogen and leukocytes were collected for fasting and 4 and 6 h after a oral fat tolerance test (OFTT) consisting of a high-fat meal with 1.000 Kcal, 27.4% carbohydrates, 14.7% protein and 57.8% lipids (30.4% saturated, 32.7% monounsaturated, 26.5% polyunsaturated fatty acids and 288 mg TC). Data were analyzed with repeated measures ANOVA, multiple linear regression, and Pearson, Spearman and partial correlations. OW adolescents showed significantly higher fasting values of TC (P=0.036), LDL-C (P=0.010), fibrinogen (P=0.036) and hs-CRP (P=0.004). All variables, except for glucose, increased in response to OFTT, but there were no interactions between group and time. body mass index z-score was positively correlated to LDL-C, TG, fibrinogen and hs-CRP, and inversely correlated to HDL-C. In conclusion, adolescents with OW showed higher TC, LDL-C and inflammatory markers levels than NW adolescents. These findings have clinical implications for prevention of chronic diseases, as we spend most of our days in a postprandial state.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
