26. Planejamento da produção e da logística para empresas produtoras de sementes de milho.
The production of corn seeds involves a complex agro-industrial production chain whose main agents must offer products of high quality and low price to stay competitive. Efficient tools to coordinate this chain are thus essential to fulfill these conditions. This work proposes a linear programming model for the strategic planning of production, storing and t

28. Incompatibilidade heteromórfica em Eichhornia Azurea (Pontederiaceae) no Pantanal da Nhecolandia, Mato Grosso do Sul
In heterostylous plants pollination between anthers and stigmas of equivalent heights are often compatible, but any other type of cross or self-pollination result in partial or total incompatibility. Eichhornia azurea is a fluctuant aquatic macrophyte, fixed in the substrate that is generally found in lagoons, rivers and flooded areas in South America. Previ

29. Development of automatic methods for evaluating dairy cows behavior in confinement system / Desenvolvimento de metodos automatizados para avaliação do comportamento de vacas leiteiras em sistema de confinamento
The current tendency of the milk production sector is to become more precise and economically feasible. It is known that differences in microclimate cause changes in animal behavior; however, conventional measures taken nowadays are evasive and can produce misinterpretation of the results. The current experiment was carried out in a commercial farm in São P

30. Rendimento e qualidade de sementes de frutos de tomate em diferentes estÃdios de maturaÃÃo produzidos nos sistemas hidropÃnico e convencional / Productiveness and quality of seeds of tomatoe in different periods of maturation produced in the hydroponic and conventional systems
The NFT - Nutriente Film Technique - has contributed to the dissemination of the commercial hydroponics cultivation all over the world and in Brazil as well. In order to evaluate the efficience of this technique in the production of tomato seeds (Lycopersicon esculentum Mill.), an experiment was conducted at a school-farm of FAZU, in Uberaba, it had been har

36. Mapeamento do palhiço enfardado de cana-de-açúcar (Saccharum spp.) e do seu potencial energético. / Sugar cane (Saccharum spp.) bailed trash yield and energetic potencial mapping.
Brazil is a developing tropical country with abundant potential for production of biomass. The sugar cane is primarily produced to obtain alcohol and sugar. Currently the sugar cane fields are burned as a pre-harvest practice. If such practice is abandoned, the trash (green leaves, tops and straws left after harvesting) could be collected and used for vapor
