Máquina para a colheita contínua de azeitona em olivais intensivos

A diminuição dos custos de colheita nos olivais intensivos (200 a 550 árvores por hectare) terá de ser encarada como tarefa urgente para que estes olivais possam ser competitivos. Nestes olivais, a técnica tradicional de colheita com vibradores de tronco encontra limitações, como a falta de espaço para o desempenho de equipamentos de recolha associados aos vibradores; mas é sobretudo, devido a ser uma técnica ...

Máquina de Colheita Contínua de azeitona

A máquina de colheita contínua de azeitona, baseia-se nos seguintes pressupostos: - utiliza o tractor agrícola existente nas explorações como fonte de potência; - procede ao destaque da azeitona das árvores abordando-as lateralmente, sem necessidade de cavalgar; - não impõe restrições ao desenvolvimento das árvores, pelo que se poderá utilizar na colheita de qualquer cultivar de oliveira; - a sua menor dimensã...

Tailoring porous structure of ferroelectric poly(vinylidene fluoride-trifluoroe...

Ferroelectric macroporous poly(vinylidene fluoride-trifuoroethylene) membranes have been produced by isothermal crystallization from the solution at different temperatures starting from different diluted solutions of the co-polymer in dimethylformamide. In this way pore architecture, consisting in interconnected spherical pores can be obtained. The mechanism and kinetics of solvent evaporation was investigated ...

Profile of three Brazilian birth cohort studies in Ribeirão Preto, SP and São L...

We describe three birth cohort studies, respectively carried out in 1978/79 and 1994 in Ribeirão Preto, a city located in the most developed region of Brazil, and in 1997/98 in São Luís, a city located in a less developed region. The objective of the present report was to describe the methods used in these three studies, presenting their history, methodological design, objectives, developments, and difficulties...

Stability and toxicity of Clostridium perfringens type D epsilon prototoxin tre...

Purified epsilon prototoxin of Clostridium perfringens type D was produced, purified, and detoxified by the stoiechiometric method of non-radioactive iodine incorporation. Different degrees of iodination were perfomed and the toxicity of the derivatives were analysed by in vivo studies. Toxicity decreased inversely to the iodine incorporation. Eletrophoretic analysis showed different levels of stability of samp...

Anaerobic treatment of wastewater from the household and personal products indu...

The anaerobic treatment of wastewater from the household and personal products industry was studied using a 16.3 L hybrid reactor (UASB and biofilter). The top of the UASB reactor was filled with coconut shells to act as the support material for the biofilter. The wastewater was characterized in terms of pH (1.0 - 12.0), COD (1,000 - 5,000 mg/L), BOD5 (700 - 1,500 mg/L), chloride (55 - 850 mg/L), ammonia nitrog...

Are birth weight and maternal smoking during pregnancy associated with malnutri...

In the late 1980's child malnutrition was still prevalent in Brazil, and child obesity was beginning to rise in the richest regions of the country. To assess the extent of the nutritional transition during the period and the influence of birth weight and maternal smoking on the nutritional condition of schoolchildren, we estimated the prevalence of excess weight and malnutrition in a cohort of Brazilian schoolc...

Health in early adulthood: the contribution of the 1978/79 Ribeirão Preto birth...

The increase in non-communicable chronic diseases of adults is due to demographic changes and changes in the risk factors related to physical activity, smoking habits and nutrition. We describe the methodology for the evaluation of persons at 23/25 years of age of a cohort of individuals born in Ribeirão Preto in 1978/79. We present their socioeconomic characteristics and the profile of some risk factors for ch...
