1. Substitution of Electrotherm by Combustible Gases in the Industrial Sector / Substituição da eletrotermia por gases combustíveis no setor industrial
This work analyzes the technical, economical and financial viability to substitute the resistive electrotherm for the direct combustion of fuel gases, such as natural gas (NG) and liquefied gas of petroleum (LGP). In order to do so, a study of the electrotherm presence in the productive process of some industries located in The Great São Paulo has been done

2. Variation in either the physical and mechanical properties and the quality of the bean (Phaseolus vulgaris L.) during the drying process and storage / Variação das propriedades físicas e mecânicas e da qualidade do feijão (Phaseolus vulgaris L.) durante a secagem e o armazenamento
There is a lack of information in the available literature on the changes that may occur in the bean during the drying process and storage time. Thus, the accomplishment of studies that would generate theoretical and practical information about a better conservation of the product are really relevant. So, this work was carried out to analyze several characte

3. Proposal of methodology for avaliation of the commercials losses of the electrical systems : the Manaus case / Proposta de uma metodologia para avaliação das perdas comerciais dos sistemas eletricos : o caso Manaus
The financial-economical equilibrium guaranteed by the concession contract made by the concessionaries before the granting power, has as a prerogative an acting management by the service agent owner. That evidences its technical and commercial control, as well as the promotion of the technological development of the granted services. In such a context, it is

4. Planejamento do "mix energÃtico" de geraÃÃo de energia elÃtrica no Brasil : uma avaliaÃÃo da aplicabilidade de otimizaÃÃo linear multiobjetivo no contexto do novo modelo institucional do setor elÃtrico
This dissertation was developed having as premisse to be including and to allow easy understanding of the displayed, preventing, however, the superficiality. It composes of three independent parts that complete themselves, in the case, the chapters 2, 3 and 4, which can be read in the order where to desire, after the introduction of Chapter 1. Each part woul

5. MANAGEMENT PROCESS INCINERATION OF HEALTH SOLIDS RESIDUES: APLICATION IN MATERIALS AND REUSING THE THERMIC ENERGY / PROCESSO DE GESTÃO EM INCINERAÇÃO DE RESÍDUOS SÓLIDOS DE SERVIÇOS DE SAÚDE: UMA APLICAÇÃO EM MATERIAIS E APROVEITAMENTO ENERGÉTICO
This dissertation covers aspects related to the incineration of the sanitary solid waste, using the thermic energy and ashes for other applications having in mind the consequences to the environment. In fact one of the major concern related to the environment is the continuous and cumulative generation of solid waste by the humanity. Therefore, we will cover

6. Simulação, projeto e construção de uma unidade piloto multi-proposito para pirolise de residuos
Pyrolysis, one of many solid waste chemical conversion processes, has been receiving a special atenttion from engineers, researches and environment specialists. The pyrolysis has been tested in many pilot plants, and some industrial plants are operated with success. Heating in a controled atmosphere absenced of oxygen, an organic portion of waste materials c

8. Thermic effect of food in lean and obese men.
A systemic reappraisal of the thermic effect of food was done in lean and obese males randomly fed mixed meals containing 0, 8, 16, 24, and 32 kcal/kg fat-free mass. Densitometric analysis was used to measure body composition. Preprandial and postprandial energy expenditures were measured by indirect calorimetry. The data show that the thermic effect of food

9. Insulin. Its role in the thermic effect of glucose.
To investigate the possible role of insulin per se in the thermic response to glucose/insulin infusions, respiratory exchange measurements were performed on eight healthy young men for 45 min before and 210 min after somatostatin infusion. Two tests were performed on separate days and each had two consecutive phases of 90 min each. Test 1. Two different rate

10. Evidence for reduced thermic effect of insulin and glucose infusions in Pima Indians.
Several authors have reported a reduced thermic effect of food in obese subjects. The hyperinsulinemic-euglycemic clamp technique has been used to measure one component of the thermic effect of food, insulin and insulin-mediated glucose disposal. We used this technique to measure the thermic responses to insulin and glucose infusions in 120 glucose-tolerant

11. Evidence that insulin resistance is responsible for the decreased thermic effect of glucose in human obesity.
The thermic effect of glucose was investigated in nine obese and six lean subjects in whom the same rate of glucose uptake was imposed. Continuous indirect calorimetry was performed for 240 min on the supine subject. After 45 min, 20% glucose was infused (609 mg/min) for 195 min and normoglycemia was maintained by adjusting the insulin infusion rate. At 2 h,

12. Effects of subdiaphragmatic vagotomy on energy balance and thermogenesis in the rat.
Subdiaphragmatic vagotomy caused chronic gastric distension and hypertrophy, and a reduction in voluntary food intake in rats fed a pelleted stock diet. These effects were minimized by feeding a more digestible semisynthetic diet. Vagotomized rats fed the pelleted diet showed lower rates of oxygen consumption than pair-fed controls, and the rise in metabolic
