1. TYPES OF HEADER, OPERATING SPEED, AND GEOMETRY OF COLLECTION FRAMES ON THE TOTAL LOSSES OF SOYBEAN HARVEST
ABSTRACT Soybean has significant economic importance in Brazil despite high production costs, making it necessary to increase the efficiency of mechanized harvest through the reduction of losses. Thus, this study aimed to evaluate the total losses in the mechanized soybean harvest as a function of the combination of header types, operating speeds, and geomet

2. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

3. SISTEMATIZAÇÃO DE CONHECIMENTO PARA O PROJETO DE PLATAFORMAS DE COLHEITA DE FEIJÃO / KNOWLEDGE SYSTEMATIZATION FOR THE DESIGN OF HARVEST HEADERS OF BEANS
Due to the need to increase in production and to the high rates of losses in the header because of machines with low efficiency in harvesting, it is presented, in this thesis the knowledge systematization needed to develop new header designs to harvest beans. This work presents the machines used for the harvest of beans, the harvesting systems, and a list of

4. Geração de mapas de produtividade para experimentos com milho no âmbito de fazenda.
ABSTRACT: Many farmers do not use precision agriculture tools due to high equipment costs and lack of knowledge about this new approach. A number of farmers have, however, conducted on-farm experiments without the help of these new and still expensive tools. One of most important equipments for precision agriculture practices is the crop yield monitor. It ca

5. Variação do espaçamento entre faixas de colheita na geração de mapas de produtividade.
RESUMO: Este trabalho avaliou o efeito do espaçamento entre faixas de colheita na geração de mapas de produtividade da cultura de milho. Avaliou-se a correlação existente entre um mapa confeccionados a partir da colheita da área total ( referencia) e outros 5 mapas, onde foram retiradas 2, 4, 6, 8 e 10 faixas de colheita. O mapa referencia foi confecci

6. Desenvolvimento de nos de chaveamento de pacotes opticos para aplicação em redes metropolitanas de acesso / Development of optical packet switching nodes for application in metro-acess networks
A new system for the generation, switching and routing of optical packets is described, aimed for use in nodes of next-generation optical networks (NGON). The optical packets are composed of an in-band frequency tone header, and a high-capacity transparent digital payload (~Gb/s), occupying separate fields. The optical node switching action includes blocking

7. AVALIAÇÃO ESTRUTURAL DE LIGAÇÕES SEMI-RÍGIDAS EM AÇO COM PLACA DE EXTREMIDADE / STRUCTURAL EVALUATION OF END PLATE STEEL SEMI-RIGID CONNECTIONS
The beam-to-column connections play fundamental role in the determination of the real behavior of steel structures. Therefore it is imperative to proper evaluate and consider the real geometric and mechanical properties of these connections, substituting the traditional idealized considerations, rigid and flexible, for the semi-rigid modelling approach. Nowa

8. iMolTalk: an interactive, internet-based protein structure analysis server
iMolTalk (http://i.moltalk.org) is a new and interactive web server for protein structure analysis. It addresses the need to identify and highlight biochemically important regions in protein structures. As input, the server requires only the four-digit Protein Data Bank (PDB) identifier, of an experimentally determined structure or a structure file in PDB fo
