1. Ceifadeira a tração animal.
O estudo teve o objetivo de construir e verificar o desempenho operacional de uma ceifadeira a tracao animal, destinada a ceifa de capim buffel, tendo em vista que o corte dessa graminea e de outras especies vegetais forrageiras destinadas a producao de feno, sera num futuro bem proximo, uma importante opcao para os produtores da regiao semi-arida do Nordest

2. Qualidade nutricional da aveia sob corte, pastejo e feno com diferentes alturas de manejo / Nutritional quality of oats under cutting, grazing and hay with different heights management
Foram conduzidos dois experimentos com o objetivo de avaliar formas de utilizaÃÃo da aveia: feno, pastejo e corte. O primeiro ensaio avaliou as caracterÃsticas estruturais, a composiÃÃo bromatolÃgica e a digestibilidade in vitro da matÃria seca (DIVMS) e da proteÃna bruta (DIVPB) da aveia branca (Avena sativa IPR 126), sob diferentes formas de manejo

3. Dinâmica populacional de plantas daninhas, desenvolvimento, estado nutricional e produção de citros em função da associação de adubos verdes, cobertura morta e herbicidas / Population dynamics of weeds, development, nutrition and citros production in function of association of cover crops, mulch and herbicides
The objective of this research was to evaluate the effects of cover crops from grass and perennial leguminous in the orchard inter-rows, mulch, produced through mechanical management with a lateral rotary mower from inter-row cover crops associated with herbicides applied in pos-emergence, on the rows, on population dynamics of weeds, soil chemical character

4. Load support capacity of a latosol cultivated with coffee plantation under associated methods of weed control / Capacidade suporte de carga de um latossolo submetido a mÃtodos associados de controle de plantas daninhas em cafeeiros.
The control of weeds plants in the coffee plantation can be made through chemical and mechanical methods, which could promote alterations in the soil structure. The objectives of this study were: a) to develop bearing capacity models, for a Yellow Red Latosol cultivated with coffee, as a function of the associated methods of weed control, preconsolidation pr

5. MÃtodos de Controle de Plantas Daninhas na Cultura do Cafeeiro e seus Efeitos na AgregaÃÃo e em FraÃÃes da MatÃria OrgÃnica do Solo / Weed Control Methods in Coffee (Coffea arÃbica L.) And Yours Effects On Soil Aggregation and Soil Organic Matter Fractions.
The coffee crop expansion in Latosol occur with high invest in varieties, fertilization, irrigation and control of insects and plant diseases. The weeds in coffee crop should be control for to avoid production loss and make easier the crop management. This work aimed to study the effect of weed control methods in coffee on soil aggregation and also on soil o

7. Efeito da associaÃÃo de mÃtodos de controle de plantas daninhas sobre microrganismos do solo numa lavoura cafeeira(Coffea arabica L.) / Effects of association of methods on weed control and soil microorganisms in coffee (Coffea arabica L.)
Combinations of methods for weed management may be useful for effective and economical control. The use of association of methods is what the farmers have of more modern in the use of this practice. However, the inadequate use of some of these methods may transform a weed species in a problem. The continuous use of a chemical may contaminate soils and interf

8. Effects of weed control area in rows on initial development of ponkan mandarin (Citrus reticulata Blanco) trees. / Efeitos da área de controle das plantas daninhas (coroamento ou faixa) no desenvolvimento inicial de tangerina Poncã (Citrus reticulata Blanco).
The objective of this research was to evaluate the weed interference on the initial development of "Ponkan" Mandarin trees grafted on "Cravo" [Citrus limonia (L.) Osbeck], through areas of weed control in rows (crown or strips) near to the young plants in the field. For that it was conducted an experiment in the experimental area of the Departamento de Produ

9. Multiple Forms of Bacterial Hydrogenases
Ackrell, B. A. C. (University of Hawaii, Honolulu), R. N. Asato, and H. F. Mower. Multiple forms of bacterial hydrogenases. J. Bacteriol. 92:828–838. 1966.—Extracts of certain bacterial species have been shown by disc electrophoresis on polyacrylamide gel to contain multiple hydrogenase systems. The hydrogenase enzymes comprising these systems have diffe
