Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

The concentration of metal pollutants such as lead (Pb), has grown and developed in populated areas due to pollution and other human activities. Consequently, the potential for achieve this element food chain has also increased. Lead is very toxic to humans, especially to children, and exposure to lead can cause adverse health effects mainly on human nervous system, bone marrow and kidneys, interfering with chromosomal or genetic processes. This paper presents an overview of the main aspects related to environmental contamination by lead from battery plants. The assessment of an area contaminated by lead in Bauru-SP next a battery factory was reported in this work as well as the entire history of monitoring, classification and application of processes applied by CETESB since 2002. Analyzing the issue in its economic aspects, we found that the degradation of the environment is directly related to the development model adopted by the capitalist system, which is based on the law of supply and demand for products and services. The data presented indicate that Brazil still needs a broader policy where government agencies, industries and population through awareness can be united for the same purpose: to preserve life

A Revolução Tecnológica vem colocando no mercado um número cada vez maior de equipamentos eletrônicos, enquanto a absorção dos impactos pelo ecossistema se torna cada vez mais difícil. A Política Nacional de Resíduos Sólidos reúne o conjunto de princípios, diretrizes, metas e ações para o gerenciamento ambientalmente adequado dos resíduos. Comparando o cenário brasileiro com medidas de outros países, a proposta é analisar os impactos econômicos e ambientais da nova lei sobre a indústria de produtos eletroeletrônicos

The main objective of this study was elaborating a diagnosis of technical conditions of Legal Reserves situation on the rural properties in Botucatu. In addition, considering the characteristics of fauna and flora and the economic aspects of these areas, it was presented alternatives to encourage the correct implantation and the effective preservation of the Legal Reserves. Because these areas contribute to the maintenance of local biodiversity and to availability of environmental services essential for all living creatures. In this study it was observed the presence of native vegetation in 13% of the rural properties’ areas in Botucatu, it is therefore necessary the recovery (reforestation) of 7% of all the rural properties’ areas, to be achieved the 20% of native vegetation (minimum area to be preserved as Legal Reserve, as disposed in Federal Law nº 12.651/12) on rural properties. A viable and significant alternative for recovery these areas, reinforced by the new forestry law, is the practice of sustainable management, that must be carried in harmony with conventional farming practices existing in the remaining areas of rural properties

Facing a global scenario where oil is scarce and the emission of CO2 in the atmosphere is a world concern, the search for new methods of energy production becomes the focus of all countries. Based on these assumptions, the wind power gains highlight and happen to be the most exploited around the world, since this does not produce toxic waste, since it uses the wind, no raw material shortage and its cost and efficiency are increasingly attractive. Taking advantage of the geographical features of Brazil, coastal and territorial extension, this study aims to analyze the feasibility of using wind turbines widely used in Germany, one of the countries with the highest production of energy through wind, in Brazil. In order to increase the energy production without causing more environmental impacts, geographical analyses will be made, and to determine the features and costs of production of this type of energy generation, and at the end of this dissertation, will finish for one of the turbines, Montana, is it feasible to install, however due to the Government's little incentive return is not very expressive. With respect to the turbine Passaat, this is infeasible to install under current conditions

This work aims to kinematic and dynamic analysis of a VW Saveiro in order to estimate the power requested to the engine with the imposed movement conditions. Thus, the study will be the basis to the specification of the electric engine, on the conversion of the internal combustion vehicle into electric one. First of all, a literature review was done in order to understand the state of the art for this issue and come up with the technical features of the vehicle in question. The next step is the identification and calculation of all forces acting on the prototype in motion, from 0 to 120 km/h, in intervals of 10 km/h, under the defined conditions of path and time. Then, were determined the values of the torque and rotation of the components from the transmission system, as well as the engine power, for each speed range. The results show the most influential forces on the resistence of the movement in each speed range, and the behavior of the torque curve is verified. Finally, it was also analyzed the implementation of pinwheels on the frontal area of the vehicle, in order to convert wind energy into electrical energy to supply the lighting subsystem of the vehicle and the proposal was validated. Limiting the maximum speed of the vehicle to 90 km/h, it was finally concluded that the power of the electric engine should be 40 HP

The processes resulting from globalization are backdrop for the work. On the other hand the Regulation Theory is theoretical north that drives research directions. Considering these two basis, we studied the formation of economic groups as a consequence of the processes of concentration and centralization of capital, giving more emphasis on their national character. We see how they went through the restructuring process in the transition from Fordist accumulation regime to a flexible system of accumulation. We 'll discuss the brewery industry and how major industry groups are currently creating a sector overview, ranging from the productive process to the forms of competition among large companies. Specifically we will see the Petrópolis Group this framework and how the company relates to the territory, and what answers we have of this relationship in terms of local development in the territories where the group entered, and territorial changes which have occurred there

A monografia apresenta um breve panorama dos aspectos econômicos do Estado do Rio de Janeiro com o intuito de destacar o papel da indústria do petróleo na economia do mesmo, assim como as rendas provenientes dos pagamentos de royalties e participações especiais aos municípios produtores. O fato é que enormes recursos são entregues a esses municípios, o que torna extremamente importante a investigação da qualidade da alocação destes. Ambiciona-se por meio deste trabalho a análise das despesas culturais dos municípios fluminenses com o propósito de identificar se as cidades que mais recebem royalties gastam relativamente mais nesta área comparado a outras. Este exame é relevante, principalmente pela dificuldade de definição do conceito de cultura e por as contas culturais municipais não serem auditadas pelos Tribunais de Contas, o que favoreceria um possível canal de desvio de verbas públicas
