| Objetivou-se com o presente trabalho estimar e avaliar as curvas de secagem do café da espécie Coffea Canephora e ajustar diferentes modelos matemáticos aos valores experimentais de quatro clones. Foram utilizados frutos de café dos clones: Cpafro 194, Cpafro 193, Cpafro 167 e Cpafro 180, colhidos com os teores de água iniciais de 1,20; 1,32; 1,51 e 1,46 (decimal b.s.), respectivamente. A secagem prosseguiu em terreiro de concreto até que o produto atingisse o teor de água de, aproximadamente, 0,10 (decimal b.s.). Aos dados experimentais foram ajustados dez modelos matemáticos, citados na literatura específica e utilizados para representação do processo de secagem de produtos agrícolas. Pelos resultados obtidos e com base em parâmetros estatísticos,... |

| Traditionally, the unit farm operations which require less muscle power is done by the women workers. The role of farm women are passive in majority of farm operations e.g. clod breaking, taking out weeds etc., assistance in sowing e.g. dropping seeds or carrying seeds, weeding and interculture, harvesting, partly threshing as well as assistance in threshing, winnowing, cleaning-grading, carrying produce as well as grain. During last three decades, many research organizations in the country are working on assessment, refinement and development of gender friendly farm equipment. Based on various study conducted on gender perspective, a need was felt to work on algorithm, as algorithms design is a specific method to create a mathematical process in solving... |

| ABSTRACT: Aeration is currently the most commonly used technique to improve the drying and storage of grain, depending on temperature and water content of the grain, as of the temperature and relative humidity of the outside air. In order to monitor temperature and humidity of the grain mass, it is possible to have a network of sensors in the cells of both internal and external storage. Use of artificial intelligence through Fuzzy theory, has been used since the 60s and enables their application on various forms. Thus, it is observed that the aeration of grain in function of representing a system of controlled environment can be studied in relation to the application of this theory. Therefore, the aim of this paper is to present an embedded Fuzzy control... |

| The use of a linear-plateau procedure to describe the response of an individual in the population has theoretical support, since the maximum potential performance of each individual is genetically determined, and any increment in intake of the limiting nutrient above maintenance will result in a linear response in output until this genetic potential, and hence requirement, is reached. However, because of the distribution of body weights and maximum potential outputs in the population, the mean response of the population is curvilinear, which negates the possibility of defining a 'requirement' for the limiting nutrient, and instead leads to the possibility of defining an optimum economic intake of the nutrient.. The Reading model describes the response of a... |
