Solar energy can be considered the largest source of energy available on earth and has attracted in recent decades, attention and interest for its rational use. The use of energy sources in a sustainable manner is essential to the survival of future generations, due to the scarcity of natural resources and their exploitation in a disorderly way. Studies related to the applications of renewable sources becomes then relevant, given its great importance as regards the conscious use of resources provided by nature, with the least possible impact on it. The present study presents an evaluation of generation potential and feasibility of implementing a solar photovoltaic connected to the grid and connected to the roofs of some buildings of the Faculty of Engineering of Guaratinguetá - FEG, to supply the demand of electric energy consumption on campus and attempting to inject a possible surplus power generation in local power grid, increasing network capacity and reducing peak loads

In the treatment plans in conventional Proton therapy are considered only the elastic interactions of protons with electrons and/or nuclei, it means, mainly ionization and coulomb excitation processes. As the energy needed to reach the deep tumors should be of several hundred of MeVs, certainly the nuclear inelastic channels are open. Only some previous studies of the contribution of these processes in the full dose have been made towards targets composed of water. In this study will be presented the results of the simulation of the processes of interaction of beams of protons in the range of 100-200 MeV of energy with a cylindrical phantom composed by striated muscle (ICRU), emphasizing in the contribution to total dose due to the deposition of energy by secondary particles alpha (α), deuterium (2H), tritium (3H), neutron (n) and hélio3 (3He), originated by nuclear inelastic processes. The simulations were performed by using the method of Monte Carlo, via the computer code MCNPX v2.50 (Monte Carlo N-Particle eXtended). The results will be shown demonstrated through the graphics of the deposited dose with or without nuclear interaction, the percentual of dose deposited by secondary particles, the radial dispersion of neutrons, as well as the multiplicity of secondary particles

In proton therapy, the deposition of secondary particles energy originated by nuclear inelastic process (n, 2H, 3H, 3He and α) has a contribution in the total dose that deserves to be discussed. In calculations of plans implemented for routine treatment, the paid dose is calculated whereas the proton loses energy by ionization and or coulomb excitement. The contribution of inelastic processes associated with nuclear reactions is not considered. There are only estimates for pure materials or simple composition (water, for example), because of the difficulty of processing targets consisting of different materials. For this project, we use the Monte Carlo method employing the code MCNPX v2.50 (Monte Carlo N-Particle eXtended) to present results of the contribution to the total dose of secondary particles. In this work, it was implemented a cylindrical phantom composed by cortical bone, for proton beams between 100 and 200 MeV. With the results obtained, it was possible to generate graphics to analyze: the dose deposition relation with and without nuclear interaction, the multiplicity and percentage of deposited dose for each secondary particle and a radial dispersion of neutrons in the material

This paper analyzes the Real Plan and its effects on two administrations of President Fernando Henrique Cardoso (FHC), a period which extends from 1995 to 2002. To this end, the study includes a brief review of the problems faced by previous plans, especially the Cruzado Plan and the reasons for the belief that it has been successfull in relation to inflation control. Additionally, seeking to describe the process of moving to the new currency towards stabilization, the paper describes the theoretical foundations of the Plan. In sequence, it defines the backround of both international and domestic monetary reform which was one important part of the Plan and therefore the reasons for the implementation of the monetary reform. Subsequently the paper deals with the effects of the Plan on the economy as a whole, covering also the way the economic measures were taken concerning the Mexican and Asian crisis, the policies used fot the exchange rate, interest rate, fiscal accounts, balance of payments, among other factors and the relationship between them. Hence, it describes the immediate and the long-term consequences of stabilization program in terms of output, employment, public deficit and debt. Therefore, it is important to note the various junctures to which the economy was exposed, and also to point out the challenges and obstacles arising from these changes for growth, which was sometimes fast, sometimes slowing down - the so-called stop and go. Of course, facts as the moving to floating exchange rate regime, the adoption of inflation targeting regime and the adoption of fiscal responsibility law along with the primary surplus policy were able to create a new economic environment and to contribute to later success of the Cardoso years

The sugarcane agribusiness has expanded by Brazil in recent years, especially with government incentives, which funded the construction and expansion of distilleries and sugar mills and alcohol throughout the national territory, as well as the expansion of the cultivation of sugarcane sugar. The state of São Paulo is the main focus of expansion in the sector, and its municipalities impacted significantly. The Pontal do Paranapanema is one of the last frontiers of cane sugar in the state, so that the culture has brought transformations mainly from 2003. Thus, we take the case of the municipality of Martinópolis analysis, which investigated some transformations in economic dynamics from 2004, the year he began the deployment of Plant Athena. For this, we conducted interviews with several subjects and analyzed statistical data from IBGE, LUPA, MAPA and CANASAT. Aware that these changes are limited to the capitalist market economy, we analyze the benefits and disadvantages brought by the activity of the plant for the population as part of economic growth characteristic of this scenario, taking it to the very prospect of local subjects. Alongside this growth, all other forms of inequality and exploitation of surplus value also grow which is not understood or perceived by residents. Hence the need to confront views and discourses on development promoted by the alcohol sector

As we focusing in the Brazilian rural area we see that it presents the spatial diversity and the different organization forms of the space arising from its diversity, tied to the different economic, social, politic and cultural contexts .These contextual diversities bring results that is not limited to the agrarian sector, but get beyond the border of the rural world, taking different ways of organization and structuring in the urban areas. The building and management of the rural spaces are constituted as an attribute of the agricultural production that in the course of the centuries made disappear and reduce significant proportions from the natural areas. In many places, the intensification of the production process gives satisfaction to the globalized markets and that return allows the reproduction of the productive conditions. In other areas the access difficulties to the market and the proximity to the developed urban centers cause the abandonment of the agricultural activity and the maintenance of property without production or with specific services (tourism, for example). That process triggers a multiplicity of factors that are defining the pace of the rural areas in Brazil. This work sought to understand all the deals of the ‘’rural’’ county of Rio Claro-SP and what’s the role and the situation that we find the familiar agriculture in the advanced urban areas, which is the case of this study. Where the agriculture doesn’t represent the flagship of the economy. It was the intention, identify what activities and practices socio-spatial are developed in the county rural area. Trying to understand the public politics acts in the promotion and encouragement to the already developed activities or even other activities that can represent the possibility of a social and territorial reproduction of the families on the country

How companies can sell their surplus production capacity of electric power in Brazil? This work was developed from the question presented and focusing on clarification of procedures to enter the Brazilian electricity market by providing basic guidelines based on resolutions by National Agency of Electric Energy, National System Operator procedures and rules of the Assembly of Electric Energy Commercialization. It features subsidy to companies that fit this profile to evaluate the possibility to sell their surplus electricity. The general aim was to analyze the procedures and the necessary steps to make this sale happen. Was developed through a literature review where an overview of the Brazilian electric sector and a case study of a company that has excess capacity of electricity, but doesn’t make its marketing. Resulted in the expected clarification as well as the incentive for companies through the information presented, the entry in this trade since power is still crucial to the country's economic growth and ensure its availability in quantity demanded is a challenge of the utmost importance for satisfactory results are achieved economic development contributing to the progress of our society

Understanding the territorial transformations is important to the geographic knowledge, especially when it is related to structural questions as agrarian one. In this way, the land acquisition to agrarian reform enables us to understand some of these transformations, represented by territorialization of landless workers in rural settlements, that are concrete results of the struggle for land that boost the policies of agrarian reform in our country. The renewal of the agrarian structure is fundamental to the concept of land reform and also provides that advances social, political, cultural, economic, etc. Classified as a country with rates of the highest land concentration in the world, Brazilian government attempts to base his actions to take in the expropriation of land the main character of the land reform. However, new policies have been gradually used to obtaining the rural settlements, in a process that Fernandes (2010) called the reconceptualization of land reform. Starting in 1985, Brazil has 63% of the beneficiaries of land reform policies settled on expropriated land, the rest is a result of incorporation policies such as land regularization, of land reform and land purchase. Such policies generate changes in agrarian structure, that is the goal of land reform, but don´t concentrate to the land ownership. This attitude of the state in coping with the agrarian question is his response to the pressures of capitalist agriculture represented by landowners and agribusiness, coping catching an intense and uneven territorial dispute with peasant agriculture, in an attempt to impose its model of development for the field. The aimed of this present study is to understand better the land reform acquisition and its implications in the Brazilian territory, in order to understand it in their multiplicity.

This paper describes a project called “Development of educational workshops on text reading, interpretation and writing in elementary school”, which took place at the São Paulo State University (UNESP) with financial support given by the PROEX-UNESP (Pro-Rectorate of Extension). This project aimed to organize and run educational workshops on reading, interpreting and writing different genres for students enrolled at a public elementary school in São José do Rio Preto, São Paulo state. The analysis of the texts produced by the students unfolded the project into two essential approaches. In the first one, it was possible to identify problems and inaccuracies in language usage, which was the starting point to prepare the minicourses that would be offered. These mini-courses promoted a deep involvement of undergraduate students (in Portuguese Language and Literature) with the practice of Portuguese teaching at the school. In the second one, 5.468 texts, which were produced during the four-year project, founded researches whose goal is to describe processes in which there is a relation between speech and writing, and are based on a theoretical framework that values the multiplicity of literacies associated with social practices experienced by the students. Thus, this extension project aimed to articulate the service to the external community – in this case, public school students - to the internal community – undergraduate students in Portuguese Language and Literature.

The modernist poet Emílio Moura (1902-1971) incorporates a strictly modern language regarding the imagistic suggesting a mainly poetry metalinguistic. That way, from the works Canto da hora amarga (1932) and Cancioneiro (1944) we attest, through the poetic analysis, that modernity Moura’s poetry takes place in confluences with ideas ranging from biblical tradition and come to the depersonalization of the modern I and questing. We objectify, therefore, demonstrate and explore the metalinguistic and intertextual character that results in the personification of poetry, as clarified muse. To achieve this, this same poetry undergoes a dualistic and pessimistic sentiment, baroque, the I that is divided into life and death, light and shadow; goes through a romantic feeling of anguish and desolation and reaches the multiplicity of the poetic speaker, which promotes a constant struggle with the language. More than draw a correlation between classical and modern ideas (in the sense that the poet creates depersonalization and appropriates of free, short prose or verse, typical of modernism), intend to supply, at least in part, the dearth of studies on the miner poet who has found fertile ground to question and analyze internally the role of poetry in the multiplicity of man and modern society to therefore conclude that universalism the Emílio Moura becomes distinctive and mature. Thus, we will check how poetic inflows corroborate both works for reevaluation and critical insertion of poetic the Emílio Moura in the context of modern/Modernist Brazilian literature

The female identity in relation to the multiplicity of roles of contemporary women and their evolution in the labor market is the focus of the work that is developed from studies of French line Discourse Analysis refered to Michel Pêcheux and Michel Foucault. The objective is to reflect on the discursive mechanisms of print media, focusing on Veja magazines covers, which, by its verbal and visual language, constructs meaning effects and disseminates certain social thruths about the female changes. Considering that this media aspect plays an important role on society's opinion formation, it is worth to investigate, analyse and describe the elements present on the covers, as seduction and persuasion objects. The work analysis material is formed by six covers published by Veja magazine in the period of 1968-2012, which raise the theme of women in the labor market and show us their evolution and the changes in the representations about the female universe and the work in society

The project Teletandem, linked to the Centro de Línguas e Desenvolvimento de Professores UNESP/Assis, promotes the interaction between undergraduates students in Languages and undergraduates students from foreign universities in order to promote the teaching of Portuguese for those who do not speak Portuguese and give an opportunity to Brazilian students to learn a foreign language. Therefore there is a different context that can result in new forms of statements produced in this specific area of human activity. The present paper aims to present a description of Teletandem sessions as a discursive gender according to the gender theory, showing the multiplicity of discursive genders that emerge during an interaction. We also intend to verify the levels of Critical Language Awareness among Brazilian participants according to the Critical Discourse Analysis.
