Indivíduos com Paralisia Cerebral apresentam desenvolvimento motor atípico, caracterizado por alterações posturais, de coordenação motora e de tônus muscular, que resulta em limitações no desempenho de atividades funcionais. Neste contexto destaca-se a prescrição e confecção de recursos de tecnologia assistiva com objetivo de maximizar as habilidades funcionais destas pessoas e prover sua inclusão social. Os indivíduos com paralisia cerebral, muitas vezes, têm dificuldade para a manutenção da dinâmica corporal, principalmente na postura sentada. O objetivo deste estudo foi o de confeccionar uma cadeira e mesa escolar adaptadas com material de baixo custo e verificar sua eficácia no desempenho grafomotor de uma criança com paralisia cerebral. O participante foi uma criança com diagnóstico de paralisia cerebral diplégica, do gênero masculino. A coleta e registro dos dados foram feitos em três momentos, com a criança posicionada no mobiliário adaptado, no mobiliário escolar comum e novamente no mobiliário adaptado, para se estabelecer a comparação. A análise de dados se deu por meio de testes estatísticos não paramétricos. Não houve significância estatística e foi verificada uma inconstância nos dados apresentados, já que não se pode afirmar ao certo qual mobiliário foi mais eficaz na realização da atividade proposta e nem se houve aprendizado motor com a sua repetição. Esse fato não invalida a adequação de mobiliário escolar ao aluno com paralisia cerebral, visto que este é um fator importante para favorecer o controle e estabilidade postural ao individuo, o que interfere na coordenação motora fina destes indivíduos, influenciando no seu desempenho em atividades escolares.

This study presents the trajectory of domestic federal public debt from Brazil in the years 2003 to 2010. Scales the amount spent on financial burden to pay the debt in relation to what was spent on items related to social development, health, education and welfare. The study concludes that Brazil despite an increase in social spending, with effective results, expenditures for the cost of domestic federal debt were much higher than social spending. The numbers were expressive in the maintenance of debt and very tiny in relation to social spending

The globalization is each day more aggressive and demanding even more that new products be manufactured and therefore be delivered to many places in the globe. Thus, an efficient and vigorous transport system is demanded. There are many ways to transport a product, but one of the most used in the world is shipping. A marine vessel presents diversified structures of size and functions. In order to this system has more efficiency, alternatives should be used to obtain important energy savings. Usually, a vessel present a propulsion system purely mechanical, therefore the use of alternatives propulsions, like diesel-electric, is increasing. This graduation work has as main focus demonstrate the functioning of a diesel-electric propulsion system, since the main characteristics of each component of the system, likewise the analysis and electrical calculation, showing the advantages in relation to the conventional diesel propulsion system

One of the biggest environmental problems of today is the climate change. Experts affirm that this global warming is related to the greenhouse effect. Its causes are directly related to human activity, especially the use of fossil fuels. In this context, companies around the world are challenged to improve energy efficiency in order to reduce the environmental impact and work toward the so-called tripod of sustainable development that focuses on the social, economic and environmental aspects of a business strategy. The first step a company can make in this regard is to conduct an inventory of emissions of greenhouse gases (GHGs). The reduction of GHG emissions in a refinery can be achieved by replacing steam turbines with electric motors to drive big machines, this reduction is achieved by relieving the steam consumption for electric power available or purchased. An important aspect associated with the reduction of GHG emissions is the best performance of the Energy Intensity Index (ERI). The objective of this study was to analyze the feasibility of the blower motorization in the regenerative cycle of a fluidized catalytic cracking unit at a specific refinery. For development work, two methods were used, the initial screening and optimization scenarios with the help of software Butyl. The results indicate that after a certain cost of natural gas this substitution becomes favorable. In addition, there is a large reduction of CO2 emissions avoided by burning fuel

The consuming of the natural resources in the agricultural sector does not represent only one external factor of the productive process, but also it implies in a bigger cost for the production, justified for this environmental degradation. In view of the necessity of evaluating the sustainment of the agricultural businesses, the use of performance indicators if makes of extreme importance. The measurement of the support through environmentalindicators is one of the most accepted forms of performing the evaluation of one given agricultural activity. In this context, the Base System for Eco-certification of Agricultural Businesses (Eco-cert Rural) developed by the Embrapa Environment at Jaguariúna/SP, has for purpose to present a method of evaluation of the agricultural businesses, not only of the point of view of the ecological performance, as well as considering the social, economic and organizational aspects. Through the analysis of the performance of the activity and the regularization of the disconformities found, it makes possible the eco-certification of the activities in the varied existing protocols, offering technologies designed to the sustainable development of the agricultural businesses. Using Eco-cert.Rural, this work evaluated the contribution of the use of mechanized harvest in sugar cane handling, front to the traditional system of manual harvest, using the fire. In the Sugar Cane Activity General Performance Index, Agrícola Rio Claro scored 2,08 of a maximum of 15. Amongst all the indicators, those wich reached performance worse had been related to the Use of Energy and the Income, by increasing fossil fuel consumptiom, and implying income concentration due to resignations of rural workers. However, the improvements on the environment quality by supressing manual harvest through fire are very significant. Beyond the great reduction in...(Complete abstract click electronic access below)

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
