Este trabalho tem como objetivo avaliar o complexo processo de constituição de oito experências de assentamentos rurais, no tocante ao seu desenvolvimento econômico e político-organizacional, localizados em regiões distintas do Estado de São Paulo. Trajetórias diferenciadas entre si marcam essas experiências, os aspectos organizacionais incidem de forma diferenciada sobre a evolução econômica, não havendo uma relação de causalidade entre desempenho econômico, existência de dissensões e alternativas de organização. Pulverização e competição são fatores presentes na tentativa de construção de um novo modo de vida. Constata-se significativa pressão para que esses novos agricultores se mtegrem ao complexo agroindustnal e ao processo de globalização econômica hoje em curso.

This text presents the first results of including research, in process, that it intends to investigate - in the period from 1950 to 1964 - the picture of the progressive political parties, the unions of the city and of the field, and the social movements marked by the national statement and for the anti-imperialism, especially those linked to the world labor perspective, discussing their proposals, differences, performances and commitments due to the political-cultural effervescence of this historical moment.

The aim of this study was to evaluate the effect of different carbohydrate sources associated with sunflower oil on intake, digestibility of nutrients and nitrogen balance in diets of lambs. Twenty lambs were used, assigned in a completely randomized design with a 2 x 2 factorial arrangement of treatments with two sources of neutral detergent soluble carbohydrate, starch and neutral detergent soluble fiber, with and without the inclusion of 4.2% sunflower oil. The dry matter intake was not affected by carbohydrate sources and the inclusion of oil. Diets with a high percentage of starch provided higher digestibility of dry matter, starch and ether extract. The different sources of carbohydrates had no interference on digestibility of organic matter, crude protein, neutral detergent soluble fiber, nonfiber carbohydrates, neutral detergent fiber, hemicellulose and acid detergent fiber. The addition of oil in the diets increased the digestibility of ether extract. The combination of 4.2% oil in the diet high in soluble neutral detergent fiber had no influence on the nutrient digestibility, otherwise, the addition of oil at high starch diet caused a significant reduction in the digestibility of organic matter, neutral detergent fiber, hemicellulose and nonfiber carbohydrates. The quantities of nitrogen intake, absorbed and retained, did not differ as sources of carbohydrates and oil inclusion in the diet. The association of 4.2 % sunflower oil to the different sources of carbohydrates in the diet does not affect consumption and nitrogen metabolism in lambs. The addition of 4.2 % oil in the diet with high starch (28% of DM diet) promotes reduction in digestibility of organic matter, of fibrous and nonfibrous carbohydrate in the diet.

This work has the purpose of demonstrating how to build a Disaster Recovery Plan. In order to achieve such objective, an adaptation of the PDCA method was applied. This plan aims resuming the IT operations as fast as possible after some kind of incident which result the stop of the services or activities. Besides serving as insurance for the continued functioning of the company’s activities, indeed your non-existence brings up risks of financial loss and threatens the company’s image. As to illustrate the functionality and validity, the method was applied in an IT department of an energy company. It was concluded that the plan was well elaborated living up to the purposes described in the objective section of this work and validating the project developed so far, having a percentage of 85% of the overall success of the systems tested

Increased demand for energy and the search for alternative energy sources are remarkable and current facts. The management of domestic solid waste is also part of the issue in view of the possibility of power generation in existing landfills, which could provide financial autonomy to the system of waste management and improve the environmental balance of landfills in Brazil, currently only used for final solids disposal. Landfill gas is a viable alternative energy source has been tested in landfills in the World and in Brazil. Thus, the research aimed to evaluate the percentage of methane (CH4) present in three sinks of gases from a landfill in the municipality of Rio Claro – SP (Brazil), and to estimate the potential methane generation over its life through the application of a mathematical model. As a result it was found that in general the percentage of methane present in the gases is significant, between 50 and 62%. It was also noted that waste with disposal time between 8 and 12 months already are in the methanogenic stage. Finally, there was a tendency to increase the generation of methane in the transition periods of rain and drought

The steel type AISI 4130 (ultra-high strength steel) is an alloy of low carbon and its main alloying elements are chromium and molybdenum, which improves the toughness of the weld metal. It has numerous applications, especially where the need for high mechanical strength. It is widely used in equipment used by the aviation industry, such as cradle-tomotor, and this is the motivation for this study. Cots are of fundamental importance, because the engine supports and maintains balance in the fixed landing gear. This equipment is subjected to intense loading cycles, whose fractures caused by fatigue are constantly observed. Will be determined the effects caused by re-welding the structure of aeronautical equipment, and will also study the microstructure of the metal without welding. The studies will be done on materials used in aircraft, which was given to study. The results provide knowledge of microstructure to evaluate any type of fracture that maybe caused by fatigue. Fatigue is a major cause of aircraft accidents and incidents occurred, which makes the study of the microstructure of the metal, weld and re-solder the knowledge essential to the life of the material. The prevention and control of the process of fatigue in aircraft are critical, since the components are subjected to greater responsibility cyclic loading

Este trabalho tem como objetivo trazer uma discussão sobre o tema da Responsabilidade Social, que embora esteja em evidência nos últimos anos, ainda apresenta campos a serem explorados, especialmente pelo mercado consumidor. Além disso, visa simplificar, ainda que superficialmente, a complexidade com que um relatório socioeconômico muitas vezes é tratado, de forma a indicar caminhos mais práticos e didáticos para que os mais diversos públicos tenham acesso e sejam capazes de aperfeiçoar suas leituras e interpretações acerca dos indicadores que constam em documentos desta natureza
