1. O uso da lógica fuzzy no controle das temperaturas de um conjunto gaseificador/combustor de biomassas / Using fuzzy logic to control the temperatures of a set gasifier/combustor of biomasses
This study consisted in designing and building a concurrent biomass gasifier that, when attached to a gas combustor, produced a mix of hot air and ambient air to be used for drying grains, among other things. It aimed at controlling the combustion zone gasifier temperature and exhaust hot air temperature. The theoretical mathematical framework chosen to deve

2. Study of bond behavior between reinforced bar and concrete with epoxi resin. / Estudo da aderência de barras de aço coladas ao concreto com resina Epóxi.
Just like others fields of knowledge, the civil construction is evolving. Hughes investments and the need for new projects improve the speed and the technology usually applied for basic infrastructures development. These scenarios achieve issues as the miss understanding of the behavior of this technological advances in long terms, caused by the few studies

3. Estudo experimental da combustão molhada na recuperação de oleo pesado / Experimental study of the wet combustion on heavy oil recovery
One way to improve the performance of the oil recovery method, known as dry forward in situ combustion, is to inject water either simultaneously or intermittently with the air, named as wet forward in situ combustion. The specific heat of the dry air is considerably lower than that of water, such that water may render a better transport of the heat generated

5. Clogging dynamics of driplines under the application of soluble iron, suspended solids and fitoplankton / Dinâmica do entumpimento de tubos gotejadores sob aplicação de ferro solúvel, sólidos em suspensão e fitoplâncton
This research project was developed to quantify possible disturbances of flow rate in drip emitters subject to the application of soluble iron, suspended solids (soil particles) in water containing organic material (phytoplankton / algae), with emitters outlet positioned down and up. Two experiments were carried out A and B during 12 months period, using 16

6. Estudo das condicionantes hidráulicas de uma ruptura de talude em São Vendelino (RS) / Study of the hydraulic conditioning factors of a slope failure at São Vendelino (RS)
A presente dissertação apresenta um estudo experimental e de simulação de fluxo de água investigando os efeitos de chuvas torrenciais sobre o solo existente em um talude da região de São Vendelino. Para este estudo foi selecionada uma encosta na qual houve duas ocorrências de rupturas rasas que deram origem a corridas de detritos num evento important

7. Evaluating the level of physical activity, the level of cardio-respiratory fitness and the cardiovascular risk in students of Medicine and Physical Education / AVALIAÇÃO DO NÍVEL DE ATIVIDADE FÍSICA, DO NÍVEL DE CONDICIONAMENTO CARDIO-RESPIRATÓRIO E DO RISCO CARDIOVASCULAR EM ESTUDANTES DE MEDICINA E EDUCAÇÃO FÍSICA
Recent studies indicate a strong association among physical inactivity, low level of cardio-respiratory fitness and the presence of cardiovascular risk factors such as high blood pressure, diabetes and obesity. Medicine and Physical Education students are involved in the field of health rehabilitation, promotion and conservation, being physical activity a pr

8. ERGONOMIC EVALUATION OF THE STRUCTURAL NAVIGATION / AVALIAÇÃO ERGONÔMICA DA USABILIDADE DA NAVEGAÇÃO ESTRUTURAL
The goal of the research is to evaluate the usability of the structural navigation, also known as Breadcrumb Trail. This tool shows the path back to the pages previously visited by users, allowing them to link back to major categories of information. There are several different types of Breadcrumbs and efficiencies will be evaluated. The hypothesis affirmed

9. Aprimoramento de um mecanismo dosador de rebolos de cana-de-açucar para o plantio mecanizado
Brazilian production of alcohol and sugar holds an important position among producing countries in the world, exhibiting 5.4 millions ofhectares ofharvested sugarcane for industry in 1998. The State of São Paulo contributes with 2.5 millions of hectares of that total. The agricultural operations of planting and harvesting represent approximately 65% of the

10. Avaliação da resistencia genetica de Coffea SPPa Perileucoptera coffeella (Guerin-meneville, 1842) (Lepidoptera-lyonetudae)
A leaf disk method was developed to evaluate resistance of Coffea germplasm to coffee leaf miner (Perileucoptera coffeella) described as follows: leaf discs 3,14 cm diameter are kept on moist sponge inside plastic boxes closed with a glass lid. The boxes are maintained under artificial light at 22 +- 2ºC with photoperiod of 12 hours. Each box fits 144 leaf

11. Variation in Susceptibility to Bacillus thuringiensis Toxins among Unselected Strains of Plutella xylostella
So far, the only insect that has evolved resistance in the field to Bacillus thuringiensis toxins is the diamondback moth (Plutella xylostella). Documentation and analysis of resistant strains rely on comparisons with laboratory strains that have not been exposed to B. thuringiensis toxins. Previously published reports show considerable variation among labor
