1. Nitrogênio e enxofre para gramínea forrageira: atributos do solo e aspectos metabólicos, nutricionais e produtivos da planta / Nitrogen and sulphur for graminaceous forage plants: soil attributes and metabolic, nutritional and productive aspects of plants
The nitrogen and sulphur availability in soil might influence plant growth, affecting the vegetal production. The objectives of this work were: a) to assess fertilization with nitrogen and sulphur rates on yield of Brachiaria brizantha cv. Marandu (Marandu palisadegrass) under establishment in a soil supporting degrading pasture of Brachiaria decumbens (Sign

2. Variações na acumulação de matéria orgânica, ao longo do holoceno, em sedimentos da região costeira de Ubatuba-São Paulo / Changes in the organic matter accumulation, during holocene, in coastal sediments from Ubatuba region-São Paulo
Changes in the organic carbon accumulation rates (Corg A.R.) and organic matter source characteristics and their relation to climate and relative sea level changes during the last 8.500 cal. yr. B.P. were investigated in two sediment cores from 2 embayments - Flamengo and Fortaleza inlets - northern coast of São Paulo State. Sediment samples were analysed f

3. Nitrogênio e enxofre na recuperação de pastagem de capim-Braquiária em degradação em Neossolo Quartzarênico com expressiva matéria orgânica / Nitrogen and sulphur for the recovery of a Signal grass under degradation in on Entisol with expressive organic matter content
Nitrogen is required for pastures establishment, maintenance and production recovery, and its effect has depended on sulphur supply, for the relationship between these nutrients in plant metabolism. The objectives were: a) to study the combinations between nitrogen and sulphur rates in soil with Signal grass (Brachiaria decumbens) under degradation; b) to ev

4. Response of the marandu grass to combinations of nitrogen and sulphur rates. / Respostas do capim-marandu a combinações de doses de nitrogênio e enxofre.
A baixa disponibilidade de nutrientes na exploração da pastagem é um dos principais fatores que interfere tanto na produtividade como na qualidade da forrageira. O presente trabalho objetivou avaliar os efeitos de combinações de doses de nitrogênio com doses de enxofre para a Brachiaria brizantha cv. Marandu, cultivada em solução nutritiva, utilizand

5. Obtenção de frações proteicas de sangue bovino : composição, valor nutritivo e propriedades funcionais
The objective of this thesis was to obtain bovine blood proteins and to study their functional and nutritional properties to be used in human foods. Blood of healthy bovines was collected from a slaughterhouse using sodium citrate to prevent coagulation and subsequently it was fractionated in a centrifuge separator into plasma and blood cell concentrate. The
