Ecotécnicas aplicáveis á construção civil no Brasil

This work approaches the main eco-efficient techniques and materials that can be used to ensure the proper functioning of the habitat with the main objective of preserving energy and reducing the ecological impact. The harnessing of energy to run a house using materials in a correct way makes it possible to achieve the goals related to its rational use. So, the more consolidated techniques need to be studied separately to determine the global effect on housing. The results obtained, with the aid of standard NBR15220 ABNT, were a series of ecotécnicas that can be used in 8 relatively homogeneous zones. This study was made to create a public awareness of the current environmental problems that society is facing nowadays and the urgent need to practice responsible use of energy

Estudo da deposição de energia das radiofrequências através do método das diferenças finitas dependentes do tempo Monografia

Radiotherapy in veterinary practice is already known and widely distributed in large specialized centers of developed countries. In early 2000, there were about 30 radiotherapy equipment specifically designed for the veterinary clinic in the United States. In Brazil, the veterinary radiotherapy is still confined to research in universities, where most of the procedures is radiation therapy performed with superficial x-ray machines, with a voltage between 50 and 150 kVp, focus-distance surface (DFS) between 20,0cm and 40,0cm. As that occurs in human medicine, new research strengthens the development and prospects for the use of radiotherapy as a safe option for treating cancer in animals. This paper presents a methodology for calculating the exposure time for superficial radiotherapy procedures in veterinary medicine for small animals (dogs and cats). The dosimetric parameters of X-rays are determined using a spreadsheet tool for Microsoft Office Excel, developed in this paper for a device Dermopan 2, Veterinary Hospital of UNESP in Araçatuba. Using the worksheet helps the veterinarian to determine the time of exposure to radiation determined for each clinical case, optimize the workflow for professionals in veterinary radiotherapy procedures, which often lack the medical physics in team and at the time of radiotherapy. The correct use of spreadsheet decreases the chances of errors in dose rates of radiation, providing a higher quality of care

Análise dos parâmetros técnicos e econômicos do aquecedor solar a vácuo, visando economia de energia

This work is about a development of a vacuum solar water heater. To accomplish this, some measurements were made, such as flow, water temperature and room temperature, relative humidity, solar power density and wind speed. It first presents a brief explanation about the global situation in relation to the accelerated use of exhaustible energy sources which can result in a breakdown of these for future generations. From this, is proposed to analyze this solar water heater with vacuum tubes during the winter season in Brazil southeastern region, under different environmental conditions. From such ideas became possible to prove through the experimental part, calculations and graphical results that technology and the performance of this device are technical and economically viable, according to the life cycle of this. It was also found that the average monthly production in a maximum heat stroke situation was 193,33kWh and minimum isolation was 57,76kWh. This reveals that this instrument should start to be examined more closely by all, as a way to reduce the use of electricity, which will protect the environment without reducing the comfort of people

O papel do gás de petróleo na matriz de energia elétrica brasileira - presente e futuro

This paper presents a study based on literature and examples found on literature of the potential of petroleum gas to be used as a primary source to generate electricity. The steady increase electricity demand in Brazil makes desirable an effective use of all available primary sources, combined with this need the momentum of the country with the discovery of the presalt reserves becomes interesting the use of this gas, often wasted, for generating electricity. The electricity generation in this work is illustrated by the cogeneration in oil refining plants that have the combined cycle thermal operation. The ultimate goal is to provide a text to identify the advantages, disadvantages and trends of this type of generation

Os financiamentos do BNDES às usinas sucroalcooleiras paulistas: potencialidades da ampliação da desigualdade regional no Brasil

The present work focuses on addressing the financing made by BNDES to sucroalcooleiras plants located in the State of São Paulo in Brazil. The study points out the Bank loans at São Paulo due to accumulation of plants technical objects that BNDES loans provide the State, with the installation of new equipment, machinery and services in canavieiros enterprises for electric power generation. Sucroalcooleiras plants are getting financing from BNDES to expand and diversify power generation in the country, mainly in São Paulo, because residential and industrial consumption of electricity grows annually. The offer of new financing to sucroalcooleiras plants for energy production Sao Paulo electric provides continued technical density in São Paulo and the expansion of regional inequality in the country. Therefore, the present study highlights for the period 2008 to 2013 the BNDES financing for are sucroalcooleiras plants in order to highlight the consolidation of technical objects in the State and show that the funding will help in the expansion of regional disparity
