13. Parâmetros solo-máquina em função de doses de resíduos vegetais e profundidades de deposição de adubo em semeadura direta / Parameters of soil –machine in function of the amount of cover residues and different fertilizer deposition depths in direct drilling
O tráfego contínuo e inadequado de máquinas em solos sob semeadura direta tem provocado alterações dos atributos físicos e mecânicos dos solos, influenciando, dessa forma, na produtividade das culturas. O experimento foi conduzido na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul, no município de Eldorado do Sul - RS,

14. Oportunidades de melhoria ergonômica das exigências físicas da atividade jangadeira em Ponta Negra Natal-RN / Oportunidades de melhoria ergonômica das exigências físicas da atividade jangadeira em Ponta Negra Natal-RN
The fishing is an activity with rafts marked by unpredictability, poor tools, physical stress, awkward postures, risk of accidents and incidents, which contribute to insecurity in the context of activity. This study aimed to contribute to reducing of physical effort and the biomechanical impacts in jangadeiro activity of artisanal fishing using jangadas on t

16. SYNTHESIS METHODOLOGY FOR SIMPLIFIED ZVT TOPOLOGIES APPLIED TO BIDIRECTIONAL PWM POLES / METODOLOGIA DE SÍNTESE DE TOPOLOGIAS ZVT SIMPLIFICADAS APLICADAS A PÓLOS PWM BIDIRECIONAIS
Among the soft-switching techniques, the zero-voltage-transition (ZVT) technique has been accepted well by the industry due its attractive characteristics, such as simplicity, low losses in the auxiliary commutation circuit (ACC), operation with soft-switching for a wide load range, and closest operation to the PWM converter counterpart. In three-phase volta

17. AVALIAÃÃO DO REVESTIMENTO A BASE DE LIGA DE NÃQUEL EM AÃO ESTRUTURAL, EMPREGANDO O METAL DE ADIÃÃO ERNiCrMo-3 ATRAVÃS DA SOLDAGEM MIG/MAG / EVALUATE OF NICKEL WELD OVERLAY IN STRUCTURAL STEEL, WITH EMPLOYMENT OF GMAW ERNiCrMo-3 ELECTRODE.
The use of nickel alloy cladding components could be more frequently in petroleum industry. The crescent naphthenic corrosion and high molecular weight of national petroleum contribute for needs of materials with more resistance to corrosion, to temperature and to pressure. At this way, how part of systematic study, this work pretends to define operational r

18. Determinação dos parâmetros de compensadores estáticos de reativos e estratégia para o projeto otimizado de reatores saturados
Due to the increasing demand of consumption, the electric energy systems have faced, in the current times, problems with its operation, being the voltage control one of the most relevant matters. To provide means to solve such problems, the use of static compensators has emerged, amongst others, as a classical alternative. Although the modern solutions are m

19. Reforma dos costumes: elite médica, progresso e o combate às más condições de saúde no Brasil do século XIX / Change of habits: medical elite, progress and fight against poor health conditions in Brazil in the XIXth century
Until the Enlightenment, due to the large influence of religion in peoples lives, the great limitations of medical knowledge and the absence of a decent public health service, the success of the healing processes was mainly conceived as Holy Grace, presented to those who were found worthy of it. Thus people were forced to rely on their own luck when threaten

20. High sensitivity Thermal Lens spectroscopy / Espectroscopia de lente térmica de alta sensibilidade
The efficiency of conventional transmission methods used to measure absorption of hightransparent materials is usually limited by light scattering and reflection. On the other hand, Thermal Lens spectroscopy is insensible to such phenomena and has been widely applied to determinate low optical absorptions. In this thesis, we have studied a recently developed

24. Sistema de codificação de video baseado em transformadas tridimensionais, rapidas e progressivas / Video coding system based on three dimensional, fast and progressive transforms
The research on video coding systems has always been looking for techniques that can reach the highest possible compression rate. This compression rate increase is generally achieved by means of increased coding complexity, which is supported by the continuous increase verified in computational power. However, in some video coding and transmission situations
