Prostate cancer is the second leading cause of cancer death in the country. Due to this factor, the interest of showing what relationship exists between vasectomy surgery and the incidence of prostate carcinoma has started. Some epidemiological studies showed an increased risk of prostate cancer in vasectomized men (Emard et al., 2001). On the other hand other authors have argued that there is no correlation (Patel et al., 2005) and there are those who said that vasectomy is linked to reduced risk of prostate cancer (Ross, 1983). Faced with an analysis of published works, such discussion remains today. The vasectomy, or deferentectomia, is a contraceptive male method, which is the section of the vas deferens of man by preventing the sperm from being expelled along with the seminal fluid during ejaculation, and is one of the most simple, economical, uncomplicated post- operative. This study aims to evaluate the process of cell proliferation and to evaluate immuno-histochemically the expression of specific markers of PCNA (Proliferating Cell Nuclear Antigen) and Ki-67, in the prostate of the gerbil after chemical induction by intraperitoneal injection of the carcinogen N-methyl -N-nitrosourea (MNU), because the regulation of the functional balance between cell proliferation and apoptosis is associated with hyperplasia and prostatic carcinoma. The experimental procedure was performed at the Laboratory of the Department of Anatomy, along with collecting the data for later analysis

With the market more and more disputed and negotiations where the customer is the main factor who decides whether the companies have conditions or not to dispute the market, industries must search improvements in products and processes targeting lower costs and better quality. With that in mind, this work will study the actual situation of a line of Tension Leveler, after cold mill process, for aluminum coil, and search new technologies, precisely the Scrap Baller machine, which will raise the quality level and the line’s productivity. It will be analyzed the justifications (reasons) for these new technologies, the history, the involved concepts, the operation, functions, the material that will be tension leveled, the limitations and tech and economic viability in comparison with the actual system. Also it will be taken a brief about the aluminum coil production in Brazil, especially the ones which destiny is aluminum beverage can, and the recycling process, that is very well done in Brazil, worldwide leader in aluminum recycling

A new approach to generating clean energy has been studied by several researchers, among which one can highlight the steam reforming of biogas. The Biogas is result of decomposition of organic matter and it hasn’t been availed in the global level, instead, the biogas has been burned in flare or discarded into the atmosphere providing damage to the environment. The generation of vector biogas energy can be realized through its steam reforming and this work examines briefly the types of digesters used for biogas generation, studying the process of steam reforming to generate hydrogen as energy vector, analyzing each step in detail, seeking to adapt its main features an ethanol reformer for a biogas reformer. Besides this it is estimated the yield of the reform process and the boiler efficiency for efficiency of the process

Environrnental issues are in focus lately, mainly due to climate change that have been registered in recent decades. Some of these changes are attributed to the increased atmospheric concentration of greenhouse gases induce, main1y due to anthropogenic emissions. These gases act by absorbing heat in the form of electromagnetic radiation emitted by the planet, and after a time interval, reissuing such radiation in various directions, including back to the surface, causing overheating of the same. Projections indicate that climate change wiIl tend to increase even more. Because of this, in recent years a number of studies are being conducted on the dynamics of inducers of greenhouse gases, especially C02, because that is primarily responsible for the development of that phenomenon. To better understand the flow of C02 are studied specific areas, as regions bordering the forests, soils that are under preparation for agriculture, urban areas, among others. Forests are an important sink for C02, because during the process of photosynthesis, this molecule is captured and used to obtain glucose. Thus, studies of the regions bordering the forests contribute enough to the understanding of the dynamics of C02. Because it requires a large amount of factors, the concentration of CO2 in a given location is very variable and this makes it much more difficult to understand their dynamics and, consequently, the action of the enhanced greenhouse effect. Being a relatively new area of study, there are many controversies about the consequences of the greenhouse effect, so that the community does not believe that climate change resulting from human action. According to them, such changes are merely natural phenomena and periodicals

This paper presents a comparative study based on literature and examples in the literature, the two main technologies for the transmission of electricity at high voltage: alternate current transmission and direct current transmission. Inside the direct current transmission will be shown two technologies currently employed, transmission by current source and transmission by voltage source, contributing to a better understanding of them. The ultimate goal is to provide a text for consultation to identify key characteristics that influence the choice of future transmission lines

The reason of this work is perform a study about using of electrical energy to identify the opportunities through rational use of electrical energy. For that it was necessary perform an analysis of hired energy against consumption. Based in a guide of energy analysis were found the main consumers and verified the main problems, which generate excessive use of electrical energy in a plastic injection factory. It was also analyzed the painting line because there are some thermal equipment that use electrical energy. Based on the data obtained will be proposed ways to reduce the needless consumption and energy use of rationally and efficiently, in addition to re-evaluate the contracted demand based on the new policy of supplying and charging.It were also proposed thermodynamics solutions to reduce the energy consumed in thermal process
