Brazil is nowadays the greatest bet of investors for the future due to its stable economy growth. The country has grown side by side with the greatest demand for electrical energy. The international appeal for renewable sources is causing a change in the Brazilian energetic matrix, raising the amount of energy generated by thermoelectric power plants. The construction of new power plants, running on biomass, requires a crescent number of capacitated personnel to run them. The Faculdade de Engenharia de Guaratinguetá – UNESP – has a steam laboratory; witch is deactivated, which has a thermoelectric plant of small capacity. The laboratory reactivation and the return of its activities can be an important tool in order to graduate engineer able to operate on such units. This paper proposes four new experiments to be simulated on the Collage’s Energy Dep. Steam Lab when it gets back to its educational activities

The area where the study was conducted is located in the central-western state of Goias. It geologically inserts the northern portion of the Greenstone Belt of Faina which belongs to the Archean terranes that fits in Brasília Fold Belt and Tocantins Structural Province. This region is known for its greenstone lode gold potential and it was heavily exploited by pioneers and prospectors, leaving many records for where they have been through. Preliminary work done by Orinoco Brasil Mineração in their required areas at the region showed that the environment is promising for gold mineralization and that the ore is controlled by structures. Therefore the objectives of this work were the geological and structural mapping in semi detail scale to improve geological, stratigraphic and structural controls present attributing possible ore understanding. With the development of the work there were recognized on the desktop three structural domains separated by a thrust fault. For each domain were discriminated the geological units ranging in gneisses, quartzites formed from coarse sediments arcoseanos, and schists. By mapping structures there were found five deformation phases, Dn-2, Dn-1, the Dn event that generated the main foliation (Sn) in high representation and two post-stages Dn with brittle late manifestations. The detail mapping of the Rattlesnake Gallery showed that the mineralized quartz vein is consistent with axial-plane foliation Sn-2 belonging to the oldest deformation Dn-2 phase and that the high grade is distributed in the hinge region folds of the same phase

Rheumatoid arthritis (RA) is a chronic illness with great potential to cause comorbidities resulting from cumulative inflammatory activities, and it contributes with the increase of disabilities and death of patients. It affects 1 to 2% of world population and usually occurs between 30 and 50 years of age. Among existing therapeutic options for the disease non-steroidal anti-inflammatory drugs (NSAIDs) still play an important part in the treatment, being widely used by patients to relieve pain and stiffness. However, this class of drugs causes many adverse gastrointestinal effects, such as dyspepsia, heartburn, nausea and vomit, and its use is one of the most common causes of peptic ulcers. Mangiferin (a glicosilated xanthone extracted mainly from the bark of Mangifera indica L.) is the main compound of an aqueous extract made from the bark stem of the mango tree. Previous studies conducted by our research group prove the anti-inflammatory action of mangiferin on an animal model of periodontitis, and its gastroprotective action has been described before. Considering these informations this study evaluated mangiferin’s potential on the treatment of RA and on gastric ulcer healing in animal models, and analyzed toxicity parameters to assure efficacy and safety of the compound as potential new drug for the treatment of the disease. RA was induced in rats by subcutaneous injection of bovine collagen and Freund’s complete adjuvant. This method presented low incidence of RA in rats, but we were able to induce the disease in 60 to 70% of the animals. Due to the wide use of NSAIDs and its potential to cause peptic ulcers, we induced gastric ulcer on arthritic rats to analyze mangiferin’s gastric healing effect. After 14 days of treatment we noticed small increase of the lesion area of animals treated with mangiferin or ibuprofen, when compared to the animals...

Increasingly, people searches for an efficient and economic way for transporting bulk materials. Transport through belts is now the most widely used mean for transporting bulk materials, used by companies from various sectors such as mining, quarrying, agribusiness, etc. There are many advantages of using a conveyor belt as compared to rail or by truck. Trucks needs a driver, have a high risk of accidents as well as a high cost for maintenance and as well as trains, after making the downloading of the material, return empty to the next load. The cost for the construction of a railway is very high, making it often impossible. The conveyor belt have a high cost of installation, but it works 24 hours a day, 365 days a year. The upper side of the belt is always loaded, the maintenance cost is average and the risk of accidents is low, causing it to be the ideal way to transport bulk materials. This monography aims to interest the reader about what is a conveyor belt, what are its main components and demonstrate the basic calculations for their sizing and selection of components. Throughout the work, scaled a belt conveyor for use in the mining sector, but the concepts demonstrated apply to the transport of any material

During the twentieth century the inorganic electronics was largely developed being present in various industrial equipment or household use. However, at the end of that century were verified electronic properties in organic compounds, giving rise to the field of organic electronics. Since then, the physical properties of elementary devices such as diodes and organic transistors have been studied. In this work was studied the properties of diode devices fabricated with a semiconductor polymer, the poly-o-methoxyaniline (POMA). Devices containing electrodes of Au and Al were fabricated with semiconductor polymer of different doping levels. We found that the rectifying behavior for the heterojunctions metal/polimer are reached only for high doping level (with conductivity greater than 1,77. 10-9 S / cm), which gives the devices characteristic of a Schottky diode. The rectifying behavior was observed for electric fields of low magnitude, below the operating field (~ 600 V/cm), while for electric field greater than 600 V/cm the a linear behavior I vs.V was obtained. We determined that this Ohmic behavior arises from the charge transport over the volume of the semiconductor material after the lowering of the metal/semiconductor barrier. In devices with weakly doped semiconductor, the electrical resistance of the volume becomes high and the process of charge transportation is dominated by the volume, for any intensity of the applied electric field

A promoção do uso racional de medicamentos (URM) é necessária para se evitar quaisquer conseqüências inadequadas relacionadas ao uso de medicamentos. O profissional atuante deve transmitir todas as informações relevantes sobre o produto, assim como a forma adequada de uso, quantidade a ser utilizada, os cuidados que devem ser tomados e também os possíveis efeitos adversos que possam aparecer. A interação do profissional farmacêutico com o paciente é uma etapa indispensável e muito importante na dispensação, e com o prévio conhecimento e com o auxílio de material técnico para consulta, o farmacêutico é capaz de realizar uma boa dispensação, fornecendo o medicamento correto que foi prescrito e, principalmente, dando informação necessária sobre o uso do medicamento em questão. O usuário está sujeito a riscos oferecidos pelo uso inadequado do medicamento, e isso deve ser evitado no ato da dispensação do produto pelo profissional atuante. Todo medicamento apresenta seus riscos, até mesmo quando utilizado de forma adequada. Por isso, a educação do paciente em relação ao medicamento é imprescindível para que o seu consumo proporcione o máximo benefício, minimizando os possíveis efeitos indesejáveis. Os riscos do uso de medicamentos fazem com que o paciente fique susceptível aos chamados Problemas Relacionados com os Medicamentos (PRM’s), que são problemas de saúde apresentados como reações negativas pelo uso do medicamento, e tem como conseqüência o aparecimento de efeitos adversos ou o efeito terapêutico necessário não ocorra. Esse usuário que não recebe a devida atenção farmacêutica no ato da aquisição e dispensação do medicamento, ou seja, não é alertado sobre possíveis reações que o medicamento possa causar e também a maneira de usar o medicamento, pode contribuir para a sua não adesão ao tratamento. Um dos principais problemas... (Resumo completo, clicar acesso eletrônico abaixo)

The Inflation targeting regime is a concept of monetary policy which was adopted by several countries in the 90’s; Brazil being among these countries, having adopted it in 1999 after a currency crisis. With it theoretical structure regulated by the New – Classical theory and having as its main characteristic the prior announcement of a numerical target for the inflation, this regime was adopted by countries attempting to achieve a prices stability. The present project is going to explain the theoretical basis of the regime, as well as its implementation process in Brazil and the criticism it received. However, the main focus will be on the discussion of the employment of the IPCA (Consumer Price Index) as a measuring index for Brazil’s inflation

The landfill biogas can be an alternative energetic resource as a fuel to electrical energy generators, although, there are not too many techniques to prospect the gas. Usually, landfills receive home waste, which in most are constituted by organic matter whose degradation by anaerobic activity produces the biogas. Geophysics is an important tool in environmental studies and the electrorresistivity, an important method employed in contaminated areas by slurry or necroslurry, including a monitoring for each contaminator flow. The electrorresistivity has not too much application in finding biogas. For this work, two biogas drains in Rio Claro-SP landfill were selected: one whose waste disposition correspond to the initial activities in the landfill and another drain whose disposition started more recently. The result consists in a higher biogas production if compared to the biogas from the older drain. The present paper consists in a monitoring along one year, with dates collection in each fifteen days. These dates were tabled in Excel 2010 program and graphics of resistivity x depth were generated. Hereafter, most variable resistivity values depth were chosen, to further graphics pluviosity x resistivity generation in Grapher 8 program and the biogas output (m³/h) in monitoring period. The use of pluviosity parameter can be justified by its influence above resistivity. The results show that there is a horizon with possibly biogas accumulation. Lastly, the method was effective, although, for any application of geophysical methods, the knowledge about its limitations is necessary; in this case the influence of pluviosity and also that the measurements were made in one single point, it will not show any side variation

Technological advances and the availability of computational resources have been facilitating the collection and processing of data. Thus, the natural tendency of the monitoring processes is the simultaneous control of various quality characteristics. In automated processes, observations are generally autocorrelated. Studies with univariate graph for processes have shown that the autocorrelation reduces the ability of this signal changes in the process. In this paper, we study the multivariate autocorrelated processes. Through simulations are obtained properties of graphs, monitoring the mean vector, the properties of graphs VMAX, in monitoring the covariance matrix, and the properties of graphs MCMAX, the simultaneous monitoring of mean vector and covariance matrix. Conclude that increasing the autocorrelation and the number of variables being monitored, reduces the power of the graphics in signal of a special cause

This study aimed to analyze the use of technological resources by teachers during their daily practice, especially the computer, in public and private elementary schools in Botucatu - SP. We know that today's society, called the Information Society and Knowledge, changes the context of education, since students have access to various information a short time. For this purpose, we use literature as a methodology and data collection through the application of a questionnaire answered by 49 students in public schools, state and private network cited. The choice of the students took place because of the diversity of schools in which they live. Our intention was not to make generalizations, but knowing more about the use of technology in these contexts from the perspective of students. The choice of subject had reason for their timeliness and necessity of knowledge, thus contributing to a comprehensive education and quality. Through data analysis, was explicit the difference between public and private schools, however, student interest was unanimous by the technologies and equitably

Estudos comprovam que os fetos desde o útero já respondem a estímulos sonoros e que a música, por sua vez, pode influenciar no desenvolvimento cognitivo, afetivo e social do individuo. É a partir de tais considerações que o presente trabalho identifica, através de levantamento bibliográfico mais aprofundado, quais os fatores que a linguagem musical pode desenvolver nas crianças e como tal linguagem se constitui num “treinamento” para o cérebro, visando, primordialmente, a busca de novas práticas de aprendizagem. Analisamos, ainda, o currículo de formação dos professores do curso de Licenciatura Plena em Pedagogia das universidades federais e estaduais brasileiras, observando a ênfase dada à modalidade do ensino de música nos cursos de formação de professores unidocentes. Por fim buscamos oferecer subsídios metodológicos, dos quais os professores unidocentes possam lançar mão para o desenvolvimento de atividades destinadas ao trabalho com musicalização infantil

Under different perspectives of interpretation and analysis, the notions of localism and universalism in the fictional production of Guimarães Rosa have been strongly explored by the criticism, especially in Grande sertão: veredas [The devil to pay in the backlands], in which these two dimensions – overlapped and complementary – become more intricate and profuse. Taking the analytical line of historical, social and political dimensions of the novel for granted – not regarding it as an essay or strict allegory of the country – the present study proposes a new reading of the composition with the interpretation of the articulation of these two dimensions in the forming of the “jagunço system” (ROSA, 1970, p.391), that is a concept created by Guimarães Rosa and which transcends the historical and sociological reality. The articulation of the social, political and cultural elements figure in Guimarães Rosa’s fiction and becomes an issue for wider debates and reflections, so that the particular element of the novel enables a universal survey. Based on diverse critical apprehensions of the novel, this paper aims to investigate the levels of the literary composition in which the local-universal articulation associated with the representation of the jagunço is constructed. In order to do that, the theoretical study is based on three dimensions of studies: a) critical essays about Guimarães Rosa, the totality of his work and specific critical essays about Grande sertão: veredas [The devil to pay in the backlands] and the “jagunço system”, b) theoretical apparatus concerning the history, the politics and the Brazilian culture related to the cangaço; and c) theoretical subsidies for the study of the narrative

The canine Transmissible Venereal Tumor (TVT) is a neoplasm of round cells that primarily affects the external genitalia of both male and female dogs with high casuistry. Its transmission occurs by the tumor cells’ implementation in the mucous membranes during the coitus or in other body parts through licking, scratching or direct contact with the tumor. The clinical manifestations vary according to the location. Despite being a malignant neoplasm, TVT’s metastatic potential is low. The diagnosis is based on macroscopic characteristics, clinical signs, cytology and/or histopathology exam, among which cytology is considered the best method. There are several treatment protocols for the TVT, among which, surgical excision, radiotherapy, immunotherapy and chemotherapy. Chemotherapy with vincristine sulfate is the elected treatment. However, more and more new alternatives have been developed, as the usage of natural products, homeopathy and ivermectina. They can be used as a unique treatment to neoplasm or combined to the chemotherapy in order to decrease the dose and the application number of the chemotherapic and its side effects
