O presente trabalho consiste na formulação de uma metodologia para interpretação automática de dados de campo magnético. Desta forma, a sua utilização tornará possível a determinação das fronteiras e magnetização de cada corpo. Na base desta metodologia foram utilizadas as características de variações abruptas de magnetização dos corpos. Estas variações laterais abruptas serão representadas por polinômios descontínuos conhecidos como polinômios de Walsh. Neste trabalho, muitos conceitos novos foram desenvolvidos na aplicação dos polinômios de Walsh para resolver problemas de inversão de dados aeromagnéticos. Dentre os novos aspectos considerados, podemos citar. (i) - O desenvolvimento de um algoritmo ótimo para gerar um jôgo dos polinômios "quase-ortogonais" baseados na distribuição de magnetização de Walsh. (ii) - O uso da metodologia damped least squares para estabilizar a solução inversa. (iii) - Uma investigação dos problemas da não-invariância, inerentes quando se usa os polinômios de Walsh. (iv) - Uma investigação da escolha da ordem dos polinômios, tomando-se em conta as limitações de resolução e o comportamento dos autovalores. Utilizando estas características dos corpos magnetizados é possível formular o problema direto, ou seja, a magnetização dos corpos obedece a distribuição de Walsh. É também possível formular o problema inverso, na qual a magnetização geradora do campo observado obedece a série de Walsh. Antes da utilização do método é necessária uma primeira estimativa da localização das fontes magnéticas. Foi escolhida uma metodologia desenvolvida por LOURES (1991), que tem como base a equação homogênea de Euler e cujas exigências necessárias à sua utilização é o conhecimento do campo magnético e suas derivadas. Para testar a metodologia com dados reais foi escolhida uma região localizada na bacia sedimentar do Alto Amazonas. Os dados foram obtidos a partir do levantamento aeromagnético realizado pela PETROBRÁS.

The Policy Pedagogical Project can be understand like a guide element of education actions, that links itself to a history social project, bringing an specific way to understand the school and its function in society. The actual brazilian legislation is based on inclusive educational policy defended since 1990 by Ministry of Education. Faced this situation the present research intends verify if the schools are organized to act into this new paradigm, using analisis of the Policy Pedagogical Projects. That's why were analized the projects of 6 public schools of basic study that attend impaired students in regular classes. Those projects were analized based on a inclusive school indicators purposed by the Ministry of Education, that is based on a specific theorical reference and on determined actions that favor the impaired student learning. The data pointed that the majority of schools shows in theorical camp assumptions vinculated to Inclusive Education Policy. However, the presented actions are still shy and limited, so there is no differentiated purpose that attend the educational needs of impaired students. It concludes that the speech about inclusive education have already been assimilated by the school, however the actions are still begginers. The Pedagogical Project colectively built, could constitute an effective instrument to think about an make a quality school, an emancipatory school for all.

ISO 26000, published in 2010, focuses on corporate social responsibility. This study presents a systematic review conducted in ISI Web of Knowledge (Web of Science) and Elsevier's Scopus databases to answer the following question: What are the barriers and motivators affecting the adoption of ISO 26000 by organizations? The articles were selected using filters that applied two inclusion criteria. The data were summarized in a table covering the concepts of ISO 26000, the motivators, and the barriers. The motivators were globalization or competition in international markets, congruence with management systems, reputation or image, relationship with employees and improvement of the organizational environment, improvement in the relationship with external stakeholders, competitive advantage and strategy, guide to corporate social responsibility (CSR), and reduction of business risks. The barriers were lack of alignment between CSR and organizational strategy; business (national and international); unfamiliarity with ISO 26000; lack of communication, tools and sensitivity to the subject; short-term focus; knowledge management; fear of not fulfilling the standard; and financial resources. Finally, an agenda for future studies was prepared.

Due to environmental concerns and the current legal requirements, companies are looking for ways to reconcile economic growth with environmental preservation. The purpose of this project is to show the stages of implementation of ISO 14001 in a chemical company and propose changes in chemical procedures creating goals to be achieved. In this paper, the study for the implementation of ISO 14001 is in Viapol ltda., where the lack of environmental management can cause enormous impact to the environment and may generate air, soil and water pollution. The project resulted in a mapping of all the processes and a broad survey of waste and emissions, generating proposals to change some of the processes and and creating programs to achieve the goals and objectives proposed in the Environmental Policy. Adopting an environmental management system (EMS), the company will reduce costs by decreasing the amount of raw material used, shooting down on waste disposal and the amount of it, and increasing productivity. By committing to the implementation of the EMS, companies will be demonstrating a proactive approach to environmental issues and enrich its image to consumers’ point of view

This paper discusses the importance of energy efficiency and the use of alternative energy sources, facing to the increasing energy demand and the concomitant economic, social and environmental restrictions imposed by society. In this work, alternative sources are illustrated by photovoltaic, micro turbines and fuel cells microgeneration systems. Energy efficiency is presented by direct current microgrids because its uses excludes the conversions of direct current (DC) to alternating current (AC) losses made with the intention of injecting energy into the electric grid and then the inverse conversion, AC to DC, in order to feed residential loads. The object of this paper is to analyze a case study and evaluates the costs and technical feasibility of a Project that combines a DC microgrid and a microgeneration system

Nowadays, there is a need for improvements in production processes for companies to be competitive, as it is an obligation of businesses, it is necessary to know about the production processes accurately, to learn where improvements in work and thus have large impacts results. The calculation of efficiency of production lines is necessary to know as much about the progress of production and for product costing, when the measurement is not suitable, it generates negative impacts on the company. Due to the impact generated by this parameter, the graduation work carry out the study of change in a method that does not include all requirements necessary, by another method known as Overall Equipment Effectiveness, and according to studies, covering various parameters, showing become more consistent. These values are contained in the pattern production which is used to fund the product, thereby also occur financial impacts. Thus the work will study the change along with the analysis of impacts caused by the change
