This work presents results derived from a study related to impact on non-controllable costs in the determination of energy taxes. This is done analyzing tax review practiced by concessionaries responsible for the distribution of electrical energy located in the Northeastern Region of Brazil, between 2003 and 2004. This Region was chosen as a study area due to the researcher s expectation in congregating companies that deliver services to markets that have similar social-economical profiles. A brief explanation related to the restructuring of the electrical sector in Brazil is presented, pointing out that there was privatization of the great majority of these companies. The study also points out the definition of regulating rules in service delivery process. The components of taxes that are practiced by these companies aimed at final consumers, as well as the market as a whole and the revision process that is executed by Agência Nacional de Energia Elétrica ANEEL for the definition of these taxes are demonstrated in the research. A brief historical of the concessionaires that were focus of the research is presented, totaling five companies. Some data used by ANEEL in the tax review process was analyzed as well as data on components of approved taxes. It is concluded that as a media 47, 49% of the components of taxes in the researched companies correspond to the non-controllable costs. These is done considering previous classification by ANEEL in the tax review process. Although, if it is considered that these companies since 2006, by the means of participation in energy auctions are able to negotiate energy prices for their own needs, it is concluded that these concession contracts guarantee the delivery of the service to the costumer in the total tribute. The percentage of non-controllable costs is 16, 27% average of the tax. This means, amongst other information, that the government has a great deal of responsibility in the formation of price practiced by these companies and its target markets

Introduces technical, economic and environmentally competitive solutions in the energy market is a great challenge for society. This work examines each of these aspects considering the production of electrolytic hydrogen with energy from wind power, solar and hydropower, in order to ensure an overview of this energy carrier. Initially, an assessment of the technical aspects is made addressing existing electrolysers technologies, its main characteristics and differences. The geographical distribution of wind, solar and hydroelectric potential in Brazil is also mapped, and a configuration scheme of a hydrogen production system is discussed. Subsequently, the economic analysis calculates the cost of investment in the alkaline electrolyser of 60 Nm³ / h, similar to the Brazilian bus powered by hydrogen project, coordinated by EMTU. Since the main input of electrolysis is electricity, is analyzed the latest energy auctions of each primary source and it is calculated the cost of production of the wind, solar and hydropower hydrogen. Postponed to this, are investigated the intrinsic environmental impacts of electricity generation process, proposing a readjustment of an indicator of ecological efficiency for the production of hydrogen. Finally, the work discusses the concept of externalities and demonstrates how the incorporation of external costs can leverage the hydrogen economy. In short, it is evident that the wind and hydroelectric hydrogens are more promising compared to solar hydrogen, whether in the economic aspect, because it achieved lower costs, whether in the environmental aspect, because it reached the highest ecological efficiency

Um dos grandes problemas socioambientais do mundo contemporâneo é a destinação dos resíduos sólidos urbanos, dentre eles a dos eletroeletrônicos, cujo volume aumenta assustadoramente. A pesquisa objetivou identificar as ações tomadas por prefeituras dos municípios do Grande ABC Paulista em relação ao descarte desses equipamentos. A pergunta que norteou este estudo foi: Qual o envolvimento das prefeituras com a sustentabilidade, quando do descarte de computadores e periféricos? Procedeu-se a uma pesquisa de cunho qualitativo e descritivo, composta por pesquisa bibliográfica e entrevistas com os responsáveis pela gestão desses equipamentos. A pesquisa se justifica por considerar que em órgãos públicos haja uma descrição clara sobre o procedimento correto a ser tomado quando do descarte de equipamentos utilizados na gestão das estruturas administrativas municipais. Como resultado, percebeu-se a existência de baixo nível de preocupação e baixo envolvimento dos entrevistados com a sustentabilidade socioambiental, principalmente em função de a legislação regulamentadora fazer com que o descarte ocorra somente por meio de venda desse material, ofertado em leilões, sem que se leve em consideração a destinação que os arrematadores darão ao lote.

Energy is a vital resource for social and economic development. In the present scenario, the search for alternative energy sources has become fundamental, especially after the oil crises between 1973 and 1979, the Chernobyl nuclear accident in 1986 and the Kyoto Protocol in 1997. The demand for the development of new alternative energy sources aims to complement existing forms allows to meet the demand for energy consumption with greater security. Brazil, with the guideline of not dirtying the energy matrix by the fossil fuels exploitation and the recent energy crisis caused by the lack of rains, directs energy policies for the development of other renewable energy sources, complementing the hydric. This country is one of the countries that stand out for power generation capacity from the winds in several areas, especially Rio Grande do Norte (RN), which is one of the states with highest installed power and great potential to be explored. In this context arises the purpose of this work to identify the incentive to develop policies of wind energy in Rio Grande do Norte. The study was conducted by a qualitative methodology of data analysis called content analysis, oriented for towards message characteristics, its informational value, the words, arguments and ideas expressed in it, constituting a thematic analysis. To collect the data interviews were conducted with managers of major organizations related to wind energy in Brazil and in the state of Rio Grande do Norte. The identification of incentive policies was achieved in three stages: the first seeking incentives policies in national terms, which are applied to all states, the second with the questionnaire application and the third to research and data collection for the development of the installed power of the RN as compared to other states. At the end, the results demonstrated hat in Rio Grande do Norte state there is no incentive policy for the development of wind power set and consolidated, specific actions in order to optimize the bureaucratic issues related to wind farms, especially on environmental issues. The absence of this policy hinders the development of wind energy RN, considering result in reduced competitiveness and performance in recent energy auctions. Among the perceived obstacles include the lack of hand labor sufficient to achieve the reporting and analysis of environmental licenses, the lack of updating the wind Atlas of the state, a shortfall of tax incentives. Added to these difficulties excel barriers in infrastructure and logistics, with the lack of a suitable port for large loads and the need for reform, maintenance and duplication of roads and highways that are still loss-making. It is suggested as future work the relationship of the technology park of energy and the development of wind power in the state, the influence of the technology park to attract businesses and industries in the wind sector to settle in RN and a comparison of incentive policies to development of wind energy in the Brazilian states observing wind development in the same states under study.

O Vírus da Imunodeficiência Humana/Síndrome da Imunodeficiência Adquirida (VIH/SIDA), é uma doença crónica, que constitui um problema de saúde pública em todo mundo, chegando a ser alarmante em alguns países principalmente nos países Africanos. Em Cabo Verde, conforme os dados estatísticos, a percentagem de população infetada pelo vírus é cerca de 0,8%. A descoberta do diagnóstico do VIH/SIDA tem como resposta os múltiplos sentimentos gerados pelo portador devido a sua fragilidade cognitiva em incorporar o diagnóstico. A trajetória da doença abrange e afeta o portador do VIH/SIDA como também a sua vivência com a família, os amigos a sociedade e o trabalho, podendo levar ao apoio como também a rejeição, com atos discriminatório e estigmatizantes. O VIH/SIDA ainda não tem cura, desta feita mostra-se que a melhor forma de combater a transmissão, é atuar na prevenção, transmitindo informações e partilhar conhecimentos, para evitar que a infeção se propaga. O estudo tem como tema “Vivência e sentimentos dos utentes portadores de VIH/SIDA, face a sua doença, em que delineou-se como objetivo geral, conhecer a vivência e os sentimentos dos utentes portadores de VIH/SIDA, face a doença. Optou-se por um estudo qualitativo, descritivo e exploratório com uma abordagem fenomenológica, sendo que o método de recolha de informações foi uma entrevista semiestruturada. A população alvo deste estudo foi constituída por cinco (5) utentes portadores de VIH/SIDA inscritos na Associação de Seropositivos VIH/SIDA de São Vicente. Na análise dos resultados mostra que os entrevistados têm perceção sobre a doença em si, em que cada um apresenta uma forma diferente de viver a doença tanto a nível familiar, como com os amigos, na sociedade e no trabalho, alguns sendo vítimas de preconceitos derivado da não-aceitação da doença. Observou-se que os sentimentos desenvolvidos pelos utentes são reversos e depende da forma como incorporam psicologicamente o diagnóstico. Um outro achado importante é o fato das intervenções de enfermagem serem insuficientes, faltando a parte humana nesses cuidados.
