The need of subsidy for the implementation of photovoltaic solar energy as supporting of decentralized electrical power generation in Brazil

The growing demand for electrical power and the limited capital invested to provide this power is forcing countries like Brazil to search for new alternatives for electrical power generation. The purpose of this paper is to present a technical and economic study on a 15 kW solar plant installed in an isolated community, highlighting the importance of the need for financial subsidy from the government. It evaluates the importance of parameters such as the annual interest rate, specific investment, the marginal cost of expanding the electrical power supply and the government subsidy on amortization time of capital invested. © 2012 Elsevier Ltd All rights reserved.

Minimal cross-subsidies approach for loss allocation in distribution networks with open access

Open access philosophy applied by regulatory agencies may lead to a scenario where captive consumers will solely face the responsibility on distribution network's losses even with Independent Energy Producers (also known as Distributed Generation) and Independent Energy Consumers connected to the system. This work proposes the utilization of a loss allocation method in distribution systems where open access is allowed, in which cross-subsidies, that appear due to the influence the generators have over the system losses, are minimized. Thus, guaranteeing to some extent the efficiency and transparency of the economic signals of the market. Results obtained through the Zbus loss allocation method adapted for distribution networks are processed in such a way that the corresponding allocation to the generation buses is divided among the consumer buses, while still considering consumers spatial characteristics. © 2007 IEEE.

Evaluating interaction with websites: Case study of a government website of the Brazilian Ministry of labor and employment

This paper presents a usability evaluation of the MTE (Ministry of Labor e Employment) website in order to measure the effectiveness, efficiency and user satisfaction regarding the website. The participants were 12 users (07 users were female and 05 male). The results indicate that although the education level of all participants and computing experience, many of them have had difficulty in finding information and do not recommend the site. © 2013 Springer-Verlag Berlin Heidelberg.

Government procurement policy in developing countries: the case of Petrobras

The aim of this article is to discuss whether public procurement policy can promote innovation by firms located in developing countries. The literature on technological learning is used to create a typology for assessing the impact of public procurement in developing countries from the standpoint of innovation. Petrobras, a Brazilian state-owned enterprise, was chosen as a case study. Petrobras is a global leader in the field of deepwater oil production technology and so offers an interesting opportunity to investigate whether government procurement in developing countries is used to promote the capability of domestic firms to develop innovations. The article presents the findings of a field survey on P-51, a platform that was ordered by the Brazilian state-owned enterprise and began producing in 2009. The case study is based on information collected from interviews with managers of Petrobras, EPC contractors and some of the firms subcontracted to work on P-51.

Geotecnologias na avaliação da suscetibilidade a movimentos de massa no município de Várzea Paulista (SP)

The disordered occupation in several cities in Brazil, is very common, especially during the rainy season, there are numerous cases of gravitational mass movements, with deads of human and builds destruction. The main objective of this work was to identify and map areas to mass movements, through the geo, the municipality of Várzea Paulista, the state of Sao Paulo. For the purpose, were prepared thematic maps of slope, geology, pedology, geomorphology and land use and occupation, which were overlaid using ArcGIS GIS Multicriteria Analysis. Each subject received a weight of influence to the outbreak of such processes and the final result was obtained map of susceptibility to mass movements of the city of Várzea Paulista. This survey found that there are many occupied areas within the city that require monitoring of the Government, especially in the rainy months, because they are in very fragile in terms of geological and geomorphological features. Considering that the data on the physical and natural aspects are scarce in the literature for this region, the results obtained in this study as well as the gathering of information of the physical and cartographic products developed, will greatly contribute to the administration of the municipality, subsidies they provide for the proper use planning and land tenure, pointing out the weak areas of the city geotechnical point of view

A evolução na prática da educação: o uso das mídias como ferramentas no ensino/aprendizagem da educação matemática

It is possible to note that the teaching done in the usual way goes against the language of youth today. It is essential that there be incentives and subsidies regarding the use of such media, whether the responsible government agencies and their members, be they principals and teachers, so there is a reform in the existing educational models and teaching. Currently, teaching is in a purely encyclopedic context of teaching models with pre-defined, ignoring the teaching based on the context in which the student lives (ethnomathematics). The objective of this work is to show how the use of audiovisual best known, such as newspapers, magazines, TV and computers can assist in teaching and learning of mathematics education, making teaching more enjoyable and inserted into the day-to-day student

A importância da ciência e tecnologia para o desenvolvimento: um estudo de caso da indústria brasileira de química verde

The objective of the research is to map and analyze the investment, strategies of develop and prospects of green chemical industry in Brazil and show the fundamental importance of basic research and applied research in the development of this industry in recent years. The complementary objectives are: (i) to evaluate the role of the Brazilian government as a catalyst, encouraging the development of green chemistry industry through incentives, subsidies and ease in credit lines; ii) mapping of relationships between companies universities and public research institutes in the field of green chemistry; iii) verification of the strategies in the world stage green chemistry, the course of time; iv) the theoretical issues and national plans, and your practicable; v) continued investment in the area, with the worry of them being affected by any matter cyclical such as the discovery of a large deposit of shale gas in the United States and a technological development of oil extraction in Brazil and vi) the pace of R&D for basic and applied in the country with the passage of time
