    1994-11-01

    This work deals with cogeneration and independent power production and, more specifically, with the feasibility and perspectives of these technologies in the Brazilian sugar-cane industry. In the first part of thesis, cogeneration and independent power production are assessed as decentralised power generation options. Some aspects of these technologies are identified, as the conditions in which they have developed in recent years, world-wide, and how they have been dealt with in the institutional structural changes under way in the public owned electric power sector in several countries. In the second part, the Brazilian sector and the sugar-cane industry are evaluated. The organisational structure of the electric power sector, the reasons of its institutional and financial crises and some structural changes proposals are discussed. In the other hand, the sugar-cane industry is studied according to the following aspects: its expansion in recent years, the concentration of the production, the alcohol production costs and why some degree of production diversification in this industrial branch is desirable. Several technological alternatives that allow a large scale electricity production in the sugar and alcohol sector are examined in the final part of this thesis. A simulation procedure was specially developed in this thesis and applied to a typical sugar and alcohol plant. With the help of this simulation procedure, technical and economic evaluations were carried out and the best alternatives are identified. Finally, their potential was calculated for the sugar-cane industry in the State of Sao Paulo, considering the possible expansion of the sugar and alcohol production and the mills that are amore appropriate to respond for this increase. The large scale electric power generation from sugar-cane by-products is an option that can bring about some advantages for the public owned electric power sector, as well for the sugar-cane one. As a matter of fact, looking from a social of view, a larger number of advantages can be identified for the society as a whole. Despite the present constraints, the perspectives are good, specially in an environment of more competition in the electric sector and in the sugar-cane industry.

    The paper relates studies regarding the natural gas distribution network interruptible branch. This new service can be appropriate for thermal power generation on flexible dispatch mode, as 'take or pay' contracts surplus jobs. The paper indicates no regulatory restraints in an interruptible network implantation. The final conclusion is that interruptible contracts can be an improvement on the distribution business and certainly can accommodate a suitable demand and supply volumes in the long-term gas market balance.

    The actual stage of technological development is strongly dependent on wide use of petroleum combustibles, in which its trade market defines the rules of socio economical and geopolitics interdependencies. The economic growth has been driven by the 'readily available - cheap energy' stimulus, limiting studies on natural sources of energy (geothermal, solar) and development of renewable ones (bio combustibles). However, economical, financial crisis may change this scenario, and new opportunities for a change in the technological matrix and in technological structure might occur. In Brazil, the 'Agenda 21', especially the PPA - Applied Research Program in the Energetic Area, intend to develop case studies and implement 'pilots projects' to research conventional and renewable sources of energy, bringing to present the value of this project, developed between 1979 and 1980, to evaluate the technical feasibility of ethylic alcohol utilization as a complementary combustible or in a total substitute for the fuel oil in boilers of conventional thermoelectric generation plants. This work presents the performance of one of the Piratininga thermal power plant's boiler, as well as the main data acquired from direct experimentation and the characteristics of this plant, from the use of ethylic alcohol as a substitute of fuel oil.

    In the Brazilian Electric System about 92% of the generated electricity is of hydraulic origin. Today the system is operating practically in the limit of your capacity. Solutions of short time to make possible the expansion of the offer of electricity generation go by the installation of cycle combining thermal using natural gas as fuel. In this dissertation, it was used the real options theory to evaluate generation assets in the Brazilian electricity sector. In Brazil, central operator dispatches a flexible thermal when the electricity spot price is larger than the operation costs. The operation decision is like an European call, where underlying asset is the electricity and the strike price is the operation cost. The value of the capacity is the sum of all decisions to operate the thermal unit, in the remaining life of unit. It was used Monte Carlo Simulation and Dynamic Programming to evaluate this model. The problem is divided in two parts. In the first part, the base case is fixed and evaluated and the expected NPV and project risk are calculated in function of contract level. In the second part, many sensibilities are done in relation to base case. At the end, the value of flexibility is calculated for each contract level. (author)

    In some countries, conditional cash transfer (CCT) programmes show an impact on maternal and child health. Juntos, the CCT programme in Peru, has been evaluated several times operationally, but seldom for maternal and child health outcomes. The objective of this study is to evaluate the impact of Juntos on children under 6 years, pregnant women and mothers of children under 17 years. Outcomes evaluated included (1) anaemia in women and children; (2) acute malnutrition in children; (3) post-partum complications in mothers; and (4) underweight and overweight in mothers. We identified Juntos eligible respondents from the Demographic and Health Surveys of Peru for years 2007 to 2013. Propensity score matching was used to identify comparable treatment and control groups, including eligible respondents enrolled in Juntos vs. those not enrolled in Juntos (individual-level analysis), as well as eligible respondents living in Juntos districts vs. those not residing in Juntos districts (district-level analysis). We then used generalized linear models to estimate prevalence ratios. Individual level analysis showed that Juntos reduced underweight in women (PR:0.39, 95%CI:0.18 - 0.85) and anaemia in children (PR:0.93, 95%CI:0.86 - 1.00). In the district level analysis, the programme was associated with a reduction of overweight in women (PR:0.94, 95%CI:0.90 - 0.98) and acute malnutrition in children (PR:0.49, 95%CI:0.32 - 0.73), but an increase in the prevalence of anaemia in children (PR:1.09, 95%CI:1.01 - 1.17). We found that Juntos had an effect on maternal and child health indicators, but further studies are required to overcome some limitations encountered here. © 2016 John Wiley & Sons Ltd.

    Restricted access to electricity, the existence of an energy matrix based on fossil fueled electricity plants and the lack of financial means by the population living in the Northern region of Brazil to afford the costs with electricity generation, transmission and distribution in the region created the need to implement cross subsidies in the country's electric sector isolated system. The subsidy policies have aimed at allowing the access to electricity for the population and industries in the north of Brazil and at promoting the economic development of this region, but have brought a great cost to society, particularly the Fuel Consumption Account (CCC), considering the environmental impacts of the fossil fuel use. This paper evaluates the current structure and the regulatory norms of the electricity sector's subsidies granted to the Isolated Systems, and intend to propose measures to reduce emissions of greenhouse gases in the thermoelectric generation plants in the isolated systems with the implementation of governmental incentives to power plants efficiency.

    Full Text Available Este estudio explica la probabilidad de confusión del consumidor por el uso de la estrategia me-too en función de tener empaques con un nombre de marca distintivo y ubicar al me-too junto al líder de la categoría. Para esta evaluación se utilizó la categoría de papas fritas cuyo líder del mercado es Margarita y se creó un producto me-too: Fristas. A través de un experimento se manipularon dos variables: tener un nombre de marca distintivo en el empaque (ausente vs. presente y ubicación en góndola (junto al líder vs. me-too solo. Los resultados muestran que tener un nombre de la marca distintivo en el empaque afecta la probabilidad de confusión, de tal forma que la presencia del nombre de la marca disminuye la probabilidad de confusión. Además, cuando el producto me-too está solo hay una mayor probabilidad de confusión que cuando está junto al líder. Este estudio confirma la importancia de que los empaques cuenten con una marca distintiva. Y su principal aporte está en demostrar que la ubicación de un producto me-too junto al líder de la categoría es una práctica acertada al prevenir la confusión del consumidor

    Full Text Available Este artigo apresenta figuras referentes à mulher junto às criminologias, bem como discute suas repercussões no código penal brasileiro. É identificada na criminologia positivista a figura da criminosa nata relacionada à prostituição, à mulher masculinizada e à atávica; bem como da vítima, seja ela criminosa por dependência do homem, seja pela necessidade de proteção do Estado. Estas figuras têm em comum o fato de servirem ao controle social da mulher. Em oposição, na criminologia feminista se verifica a figura da mulher emancipada, que não busca no direito penal a solução de conflitos que são de ordem social, econômica e política.

    Background: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of the nutrition transition experienced by many low- and middle-income countries. Objective: We estimated the association of participation in Peru’s Juntos CCT with anthropometry, language development, and school achievement among children aged 7–8 y. Methods: We used data from the Young Lives Study of a cohort born between 2001 and 2002. We estimated associations of the Juntos program with height-for-age z score (HAZ), body mass index–for–age z score (BAZ), stunting, and overweight at age 7–8 y separately for children participating in the program for ≥2 y (n = 169) and children participating for overweight (ATT: –22.0 percentage points; 95% CI: –42.5, –2.7 percentage points; P = 0.03). We observed no significant associations of Juntos participation with receptive vocabulary or grade attainment. Conclusions: CCT program participation in Peru was associated with better linear growth among boys and decreased BAZ among girls, highlighting that a large-scale poverty-alleviation intervention may influence anthropometric outcomes in the context of the nutrition transition.

Isso causa um grande problema ao neurocirurgião; a colocação de um clipe de aneurisma neste local só irá aumentar a hemorragia. Nossa sugestão técnica resume-se à clipagem do aneurisma sobre um pequeno fragmento de músculo temporal colocado no local da ruptura. É bastante simples mas bastante útil, devendo ser lembrada no momento da ruptura.

    Full Text Available No HCFMRP-USP, a enfermagem tem implementado ações dirigidas aos pais com grupos de apoio, treinamento para alta e envolvimento deles no cuidado progressivo do filho. Procurando expandir essa assistência, implantamos um programa de apoio envolvendo atividades lúdicorecreacionais junto aos pais de bebês hospitalizados nos berçários de risco, cujo relato constitui objeto do presente estudo. As intervenções são executadas por alunas de enfermagem, que se reúnem semanalmente com os pais, por 2 horas, desenvolvendo técnicas de dinâmica de grupo, atividades de lazer; oficinas de criatividade envolvendo atividades manuais; discussão de temas básicos. Através dessas novas estratégias de cuidado, espera-se contribuir com o processo de construção de uma assistência mais integral e humanizada na área de neonatologia, tendo como foco a família.

    Full Text Available Census data reveal that suburban communities are becoming increasingly diverse. Once considered affluent and predictable places, American suburbs are now confronting increasing poverty rates as well as ethnic, racial and linguistic diversity. Currently, more than half of US Latinos live in the suburbs. Schools and public institutions such as museums are challenged to provide programming that meets the needs of Latinos, who are disproportionately poor (Ackerman and Tazi 2015:3. Promoting school readiness among Latino children is an important effort in maximizing the potential and educational attainment of this growing population. In one suburban community, a school-museum collaboration resulted in a bilingual parent-child program promoting school readiness and social inclusion for Latino families. Arte Juntos/Art Together engaged parents and children using art andculture-based activities that developed observation skills, creativity, critical thinking, vocabulary, and aesthetic appreciation. Celebrating diverse perspectives and self-expression, the program provided access to museums as enriching spaces for informal learning, personal empowerment and social inclusion

    Full Text Available Nesta pesquisa, verificou-se o modo como professores e alunos da 4ª série do ensino fundamental de oito anos de três escolas públicas de uma cidade de médio porte no norte do Estado do Paraná compreendem o significado de leitura. Essa verificação foi efetuada por meio de observação em sala de aula e da aplicação de questionário. Reconhece-se que, desde sempre, a leitura teve grande relevância na sociedade e, nesse começo do século XXI, ela tem se mostrado ainda mais forte, devido ao aumento das publicações impressas e das demais formas de sua manifestação, como a imagem, divulgada amplamente nos meios sociais. Ainda que no Brasil o nível de desempenho da leitura dos estudantes do Ensino Fundamental não se mostre satisfatório, os resultados obtidos nesta pesquisa, junto aos alunos, revelam o fortalecimento dos laços que eles estabelecem com a leitura. No entanto, o ato prazeroso de ler nem sempre surge espontaneamente ou, ainda, o leitor em potencial pode ser sufocado por diversos fatores influenciadores, daí a necessidade da intervenção de instituições próximas às crianças, a fim de que se tornem leitores, e mais que isso, leitores críticos, transformadores da sociedade. Neste sentido, apresentam-se neste artigo contribuições com vistas ao ensino da leitura na escola.In this research we analyzed the way teachers and students from the fourth grade of elementary school, in eight years, at three public schools in a midsize city in the north of Paraná State understand the meaning of reading.

    Full Text Available Neste trabalho, apresenta-se um estudo das relações do comprometimento com a ética profissional junto aos profissionais da área contábil, na tentativa de averiguar se o nível de introjeção dos valores éticos influencia o seu nível de comprometimento. Na etapa empírica, foram utilizados dois instrumentos de mensuração, sendo um relativo ao comprometimento organizacional de Medeiros (2003, adaptado para a profissão, com 28 (vinte e oito indicadores e outro com 20 (vinte, construído a partir do teorizado por Lisboa et al. (1997, que foi inspirado no código de ética do contador gerencial do Institute of Management Accountants, como um conjunto de quatro preceitos mínimos: a competência, o sigilo, a integridade e a objetividade, que na visão dos autores, representam as bases mínimas exigidas num código de ética, analisados a partir das técnicas de análise fatorial, regressão linear e test "t". Constatou-se que o comprometimento é influenciado pelo nível de introjeção ética e que existe diferenciação no comprometimento por parte das duas categorias profissionais: técnicos e contadores. O resultado do estudo mostra que o profissional de nível superior tem seu comprometimento influenciado diretamente pelo nível de introjeção dos deveres éticos da profissão em quatro bases diferentes, e o técnico em contabilidade em duas. O estudo mostra, também, que a objetividade é o maior preditor do comprometimento, sendo esse mais bem evidenciado pelos aspectos instrumentais e normativos, possibilitando considerar que as relações de troca e de necessidade se apresentam como salientes diante da atuação ética dos contabilistas.This paper presents a study in commitment issues related to professional ethics amongst professionals in Accounting.

    Full Text Available O presente estudo buscou identificar e analisar como está ocorrendo o relacionamento entre instituições e vinícolas exportadoras no ambiente institucional da Campanha Gaúcha, baseando-se, para tanto, no modelo proposto pela autora Christine Oliver (1991. Além disso, pretendeu-se verificar se as vinícolas fazem uso do isomorfismo em suas respostas às pressões do ambiente institucional para obterem legitimação na comunidade vitivinícola. Para tanto, foram revisados temas relativos à teoria institucional, em suas vertentes respostas estratégicas, pressões ambientais e isomorfismo, bem como se buscaram, em sítios eletrônicos e artigos acadêmicos, etc., pressões oriundas do ambiente institucional que impactem diretamente nas atividades das vinícolas em estudo. Foi realizado um estudo qualitativo, tendo como instrumento para coletar os dados primários, junto a três vinícolas que compunham a amostra, um roteiro de entrevista semiestruturado com três questões abertas. Entre os resultados, verifica-se que todas as vinícolas adotaram respostas estratégicas menos flexíveis face às requisições dos consumidores por práticas ambientalmente corretas.

No entanto, assim como essas crianças, também os alunos com altas habilidades necessitam de um atendimento especializado, pois ele também é um sujeito da Educação Especial. Nesse sentido, este artigo apresenta a definição de altas habilidades, baseada na teoria de um pesquisador norte-americano e, como foco principal algumas questões que envolvem o professor de forma mais direta com o aluno com altas habilidades em sala de aula. Entre elas estão: questões sobre a aprendizagem escolar desses alunos, bem como os fatores que fazem parte desse processo, estratégias de ensino e a importância da identificação dos alunos com altas habilidades.Palavras-chave: Educação Especial.

    Full Text Available Este estudo parte da premissa de que hospitais com alto nível de complexidade incorrem em maiores custos quando comparados com hospitais com médio e baixo nível de complexidade. A lógica econômica que sustenta esse raciocínio é que a resolução de diagnósticos mais complexos exige mais investimentos tanto em ativos quanto na capacitação do seu corpo clínico e administrativo. Diante disso, este estudo teve como objetivo verificar se os preços dos serviços hospitalares praticados por hospitais privados junto à operadoras de planos de saúde seriam capazes de discriminar os hospitais de acordo com seu nível de complexidade (alto, médio e baixo. Foram coletados dados relativos a oito serviços em cinqüenta e quatro hospitais privados localizados na cidade de São Paulo. A amostra não é aleatória e foi obtida mediante a análise das faturas de 648 pacientes internados nesses hospitais no período de 2006 e 2007. A Análise Discriminante foi realizada e os resultados indicam que, para a amostra objeto deste estudo, os preços praticados pelos hospitais privados pelos serviços prestados junto a operadoras de planos de saúde não discriminam os hospitais de acordo com seu nível de complexidade, ou seja, há indícios de que, para a amostra selecionada, os planos de saúde não estejam atribuindo importância para o nível de complexidade dos hospitais privados no momento de pactuar os preços dos serviços.This study assumes that hospitals with a high level of complexity resulting in higher costs when compared with hospitals with low and medium level of complexity. The economic logic that underlies this reasoning is that the resolution of more complex diagnoses requires more investment on both the active and the training of clinical staff and administrative staff. Thus, this study aimed to determine whether prices charged for hospital services by private hospitals by the health plan operators would be able to discriminate among

Esta pesquisa foi desenvolvida por meio de estudo de caso de uma criança com Transtorno Global do Desenvolvimento atendida de julho/2002 a novembro/2004. Os recortes do material clínico retratam o percurso seguido ao longo do eixo da história do paciente enfatizando os momentos significativos que geraram desenvolvimento do processo terapêutico fonoaudiológico no que se refere à comunicação oral e integração social no ambiente familiar. O enfoque das estratégias clínicas foi direcionado para propiciar um ambiente físico e emocional capaz de promover experiências constitutivas que respeitem a singularidade de cada paciente levando em conta a realidade da família e da comunidade onde se encontra inserido aquele núcleo social. Portanto, em nosso entender, a atuação fonoaudiológica pode ser direcionada para a criação de situações que favoreçam o processo [de cada paciente] de inclusão na vida cotidiana, com o respeito que todas as pessoas merecem.The aim of this study was to reflect about and discuss the role of a speech-language pathologist with the family of a child with Pervasive Development Disorder.

    This paper analyses various thermal schemes of the world wide most used cycles in gas-steam thermoelectric power plants. The combination of gas turbine cycle with the steam-gas cycle in thermoelectric power plants is performed in several ways, resulting in different thermal schemes, used equipment and operation plant basic characteristics. The thermal scheme of a gas-steam power plant is a determinant factor for the definition of energetic, economic and ecological characteristics. For the comparative analysis various quantitative indexes are presented, as for example: the heat fraction supplied to the gas turbine cycle and the cycle binary rate.

    The electric power consumption in Brazil is growing about 4.2% a year, according to ELETROBRAS Decenal Plan in 1999. The capacity of installed electrical power is approximately 50000 MW, of the which 75% are in the Southern, South eastern and Middle western regions of the country. The growth rate indicates the need of an increase of the installed capacity of 2100 MW a year to avoid the risk of the lack of energy. On the other hand, the hydraulic potential sources of the region are practically exhausted and the government budget is low for this kind of investment. Therefore the solution would be the construction of new thermoelectric plants, with the possibility using natural gas and cane bagasse. The present work consists of the evaluation of the best option considering criterion of minimum cost for kWh of energy produced for the thermo electrical plants selection. Thermo economic analysis was made evaluating the production costs of steam and electricity in exergetic basis. The results show that the power cycles and cogeneration plants that use natural gas and cane bagasse are much more economical than the ones that just use natural gas, with 48% reduction of steam cost, 40% reduction of electricity cost generated b the steam turbine in the power cycle and 37% reduction of electricity cost generated by the steam turbine in the cogeneration plant, for cane bagasse price at 4 US$ /t and natural gas price at 140 US$/t.

    With the aim of providing subsidies to understand how scientific collaboration process occurs and develops into a research institution, particularly IPEN, this study used two methodological approaches. The first used the social networking analysis (SNA) technique to map the scientific collaboration networks in R&D of IPEN. The data used for the SNA technique were extracted from the technical and scientific publications database of IPEN, using a computer program, and were based on co-authorship from 2001 to 2010 period. These data were grouped into consecutive intervals of two years generating five biennial networks. This first approach showed several structural features related to collaborative networks, especially the most prominent authors, distribution of components, density, boundary spanners and aspects related to distance and clustering to define small world networks. In the second approach, partial least squares, a method to structure equation modeling, was used to evaluate and test a conceptual model based on personal, social, cultural and circumstantial factors to identify those that best explain the propensity of an IPENs author in establishing links of collaboration in R&D environments. From the consolidated model, we evaluated how much it explains the structural position of an author on the network based on SNA indicators. In this second part, the data were collected through a survey research using a questionnaire. The results showed that the model explains about 41% of the propensity of an IPEN author in collaborating with others authors, and in relation to the structural position of an author on the network, the explanation power of model ranged between 3% and 3.6%. Other results have shown that collaboration between IPEN authors have a positive correlation with moderate intensity to productivity, in the same way, the most central authors in the network tend to increase its visibility. Finally, several other bibliometric statistical indicators related to R&D collaboration network of IPEN were determined and unveiled, such as the average number of authors per publication, the average of publications by IPEN authors, the total number of publications, the total number of authors, among others. Thus, this work provides a theoretical and empirical contribution to the studies related to scientific collaboration and to the transfer and preservation process of knowledge, as well as various subsidies that contribute to the decision making context in R&D environments.

    LópezLeiva, Carlos A.; Khisty, Lena Licón

    2014-06-01

    In this paper, we discuss the characteristics of microaggressions based on minority language(s) as a form of discriminatory practice against non-dominant students in the mathematics context. Microaggressions are subtle, brief, and commonplace verbal, behavioral, or visual negative slights or insults toward people of color. We extend the concept of microaggression to include discrimination based on a minority language. We draw on our work with Latinas/os in the USA to demonstrate the occurrence of microaggressions in the teaching act. Revealing microaggressions based on language has the potential of creating more equitable learning environments for non-dominant students and can point to possible directions for future research and improvements in the preparation of teachers who serve non-dominant students who speak a language other than the school's official language.

    Environmental impacts from combustion processes, in addition to fuel supply problems, have restricted the use intensification of natural gas thermoelectric, under rigorous action of the control and inspection institutions about emissions. The demand for decentralized energy generation systems has motivated the innovator technology development and, therefore, a diminished natural gas thermoelectric prototype has been developed by the Federal University of Ceara. This prototype utilizes non-conventional technologies: 'Superadiabatic Boiler' and 'Tesla Turbine', in which theoretical and experimental studies are performed. That novel boiler model presents lesser specific consumption and CO and NOx emission levels. A not well known concept at industry is implemented into that project, 'Porous Media Combustion', which modifies the combustion process phenomena. The turbine presents operational robustness and versatility because it allows wide rotation range and simple adaptation to commercial generators. Project parameters are investigated, such as: torque and power-weigh and geometry ratios. That micro-thermoelectric shows potential for the self-sustainable development of geographically distant communities and for co-generation at industry. It is possible to serve to low power energetic demands without requiring much professional experience for operation and maintenance. (author)

    This paper aims to highlight an innovative system designed to generate bioenergy in Toledo - PR, applied in a rural residential property. This system is composed by a simple digester model, because it eliminates masonry and hood storage. Cattle slurry and water from barn's floor cleaning are conducted to an anaerobic biodigester chamber. Biogas production is stored in a polypropylene canvas balloon. After compression, the biogas is used to replace liquefied petroleum gas in central water heating and cooking foods. The wood used in sugar cane molasses has been replaced with higher efficiency by biogas. Also was installed Otto engine providing thermal and electrical power generation at the same time. The electrical power output is biphasic and about 70 Amperes. This system deployed in rural property provides energy self-sufficiency and contribute to the reduction of operational costs of the property. (author)

    The world energy matrix shows a rapidly moving to replace part of fossil fuels by biomass. The demand for diesel fuel, more than any other derivative, is determined a very evasion of foreign exchange through import of crude oil and diesel fuel itself. Within this panorama the diesel fuel becomes critical, because any impediment to imports would bring a immediate reflecting in the country transport system, since this system is based primarily in road transport. Besides, the world's oil reserves are becoming increasingly scarce, them it is imperative that research can be carried out to find alternatives that may minimize or even reach a level of full independence, not just of oil diesel, but also of all oil derivatives. However, if the few changes in traditional spark ignition engines (the gasoline engine) enabled the use of ethanol, first as a mixture and then as full replacement of gasoline, it does not occur in the case of diesel oil. Among the various alternatives for partial replacement of diesel oil, the use of mixtures anhydrous ethanol-diesel stands out as the most simple application, since there is great availability of ethanol and is not needed any change in the original engine. The main problem with this type of alternative is the low solubility of ethanol in diesel fuel, and the little stability that these mixtures have with the change of temperature and humidity environment. One solution to increase the solubility and improve the stability is to use a third substance that, acting as co-solvent, allows levels of mixtures with the best level of stability and higher rates of replacements. Among the various alternatives for use of co-solvents, was chosen initially the butane. Various physical and chemical parameters were evaluated for diesel and for mixtures of fuels.

    The national integrated system has always had hydroelectricity as its main source of energy supply. However, a long period of lack of investment in sector put the country in a complacent position in which there was an overabundance of energy supply. The subsequent power shortage of 2001, led to a long term strategy of assuring supply with perspective of attending demand quickly and guaranteeing the security of the system by exploiting a source of energy rarely used in the country: thermal energy using natural gas. For this reason, the federal government launched the PPT Program (Priority Program of Thermoelectricity) with the aim of stimulating investment in thermo electrical plants, utilizing natural gas which is cheaper and less polluting. However, investment by the private sector did not fulfill expectations even with regular production, financial incentives of the government and favourable points through thermal generation using natural gas. Therefore, PETROBRAS decided to assume the risk and form partnerships to assure investments in thermo electrical plants. In the strategy of implanting thermal plants, who would be responsible to carry out this process along with guarantees of supply, was not properly defined. The establishment of thermal plants without a regulatory framework and undefined investment plan, compromises the essence of its creation. It is from this angle, that evaluates the recent collapse of energy of the Northeast region and the effective implantation of thermoelectricity utilizing natural gas. (author)

    This paper presents a prototype of a modeler aimed to obtain 3-dimensional geologic scenarios which simulate canalized petroleum reservoirs from information about the geometry of the geologic units that compound them and the wells' profiles, using as a base the 'Namorado' Field (Campos Basin, Rio de Janeiro). The connected volumes that form a reservoir have proper shapes, which can be hardly modeled by known surfaces with parametric description (or implicit). The geologic units implemented by the prototype are formed by turbidity canals, which are represented by poliedric surfaces through triangulated webs. The 3-dimensional models that represent the reservoir geometry were obtained using the method of superposition of geologic units, according to the natural depositional sequence, through intersection operations between the geologic units modeled as poliedric surfaces. Limit boxes are used to optimize the calculus of intersections in the triangulated webs, using the algorithm proposed by Lo and Wang (2004). The validation of the 3-dimensional model, that models the reservoir, is done through the calculus of interiority, obtained from the implicit equations that describe the transversal sections of the canal's surface, whose domains include the identified intervals as reservoir in the data of previously informed wells.

    The energy generation externalities have both positive and negative sides. The conventional sources, including fossil and nuclear fuel, have environment, political, economical and social negative externalities. The environment one affects the world climate, the political one includes the wars caused by oil control, the governmental financial support is economical aspects, and black outs, that affect all citizen's job, are a social example. The photovoltaic solar energy has a negative externality when the lead-acid battery is used into stand-alone systems. This batteries need special attention because has harmful components that can pollute the water. The use of other way to storage the energy is a solution to this, like non pollute batteries, electrostatic accumulation, flywheels, compressed air, hydrogen fuel cell or thermo accumulation. The PV system can be grid-connected too; this solutions have positive externalities, because the solar collector can replace the electric shower, reducing the transmission system demand during the peak time, and saving some energy from the conventional power plant during drought season. A house's roof can support more than twice of PV system needed to supply the energy of the house, so the potential to use the solar energy without needing new places is huge. The consciousness that the Earth is but one country, and mankind its citizens, should be adopted for all mankind, because the environment pollution of a specific place affects everyone, and the negative externalities must be calculated. The PV prices is getting cheaper each year, forecasting 45% of price reduction into the next 10 years. The governmental support to use solar hot water at residences, research and nationalization of the PV production are necessary to amplify the positive externalities of the solar energy. (author)

    The problematic associated to the Distribution Generation (DG) impact has several implications (economic, technical and environmental). The DG can to influence positive (reduction) or negatively (increase) about the level of losses. The impacts caused by the use of DG influence directly on the economic incentives that can get the DG. This paper presents some of the benefits and technical limitations in the use of DG in the provision of active and reactive power for each of the levels of transmission, sub transmission and distribution. An economic review where there is a decrease in the total cost of production of electric energy by the use of DG is shown. This reducing costs, can be used as an additional remuneration for the DG or used also in new investment in the expansion of DG without overlooking that within these technologies, deals are the Renewable Energy Sources.

    This paper aims to highlight an innovative system designed to generate bioenergy in Toledo - PR, applied in a rural residential property. This system is composed by a simple digester model, because it eliminates masonry and hood storage. Cattle slurry and water from barn's floor cleaning are conducted to an anaerobic biodigester chamber. Biogas production is stored in a polypropylene canvas balloon. After compression, the biogas is used to replace liquefied petroleum gas in central water heating and cooking foods. The wood used in sugar cane molasses has been replaced with higher efficiency by biogas. Also was installed Otto engine providing thermal and electrical power generation at the same time. The electrical power output is biphasic and about 70 Amperes. This system deployed in rural property provides energy self-sufficiency and contribute to the reduction of operational costs of the property. (author)

    Full Text Available Segregation and / or concentration of foreign populations in some schools is a phenomenon raised by the international scientific production, a recurring theme for the media, and an issue discussed in the society at large and among the educational community more specifically. This situation is seen as crucial to the debate about the presence of foreign immigrant students in the educational system, and questions the ability of this system to promote equality. After giving a general idea about this phenomenon as presented by the scientific production and national and regional statistics, in this article we show our empirical work conducted in two neighborhoods in two cities in Andalusia where we observed the concentration process of immigrant / foreign population over several academic years. With the help of the discourses constructed in these places, we will highlight the existence of inequality, interpret the reasons behind it.La segregación y/o concentración de poblaciones de nacionalidad extranjera en determinadas escuelas es un fenómeno abordado por la producción científica internacional, un tema recurrente para los medios de comunicación y un hecho plasmado en los discursos que, desde la sociedad en general y en concreto desde la comunidad educativa, se plantea como central en el debate sobre la presencia de alumnado «extranjero/inmigrante» en el sistema educativo y que pone en cuestión la capacidad de este para promover la igualdad. Tras presentar de forma general dicho fenómeno, visto por la producción académica y las estadísticas nacionales y regionales, mostramos nuestro trabajo empírico llevado a cabo en dos barrios de dos ciudades andaluzas, donde observamos los procesos de concentración de la población «inmigrante/extranjera» a lo largo de varios cursos escolares. Con la ayuda de los discursos construidos en estos lugares trataremos de interpretar cuál es la lógica de un fenómeno que sigue moldeando un tipo de escuela que, más que gestionar la diversidad, construye la diferencia que termina traduciéndose en desigualdad.

    Full Text Available Despite being a strategy that is widely used by political parties, the study of electoral coalitions is still incipient in Latin America. The few studies done until now regarding Mexico have focused on elections for executive offices or for seats as federal deputies. This article represents an initial analysis of coalitions for the election of local deputies, starting from an original base containing compiled information on 180 electoral contests from the 2000-2016 period. The data confirm that parties not only develop different strategies among states and over time, but even within diverse districts in the same election and in one and the same state.

    Full Text Available La concepción de memoria analizada desde dos perspectivas, una psicológica y otra como proceso colectivo, y teniendo en cuenta la influencia por la introducción de tecnologías en el contexto cotidiano, deja entrever que la educación adquiere un papel importante al formar el puente que comunica estas instancias, pues ellas hacen parte de la construcción de identidades y subjetividades en nuestros días. Por ello, el siguiente artículo propone analizar estas casi antagónicas concepciones sobre la memoria y sus implicaciones teóricas y metodológicas -más no didácticas- en la educación.The conception of memory analyzed from two perspectives, one of these being psychological and the other one being a collective construction, and taking into account the influence of new technologies that exist in our current context, shows that education has a very important role because it is considered to be the bridge between these two conceptions, as both of them are essential parts of identity and subjectivity construction today. As a result, the purpose of the following article is to analyze these two points of view about memory and its methodological and theoretical implications in education.

    2015-01-01

    Full Text Available Las secuelas negativas de la segregación residencial de los hogares más pobres han sido ampliamente descritas, pero poco se sabe sobre las consecuencias de la proximidad entre hogares de distinto estrato socioeconómico. Los estudios existentes no llegan a consenso: la proximidad es interpretada por algunos como una expresión distinta de exclusión; otros piensan que esta cercanía permite mejorar las oportunidades de integración de los hogares de menores ingresos. Este estudio busca aportar a esa discusión retrotrayéndose a las dinámicas subyacentes a las consecuencias de la proximidad residencial en términos de inclusión y cohesión social. Por medio de un estudio cualitativo de casos, se concluye que la proximidad se asocia a dinámicas de inclusión social de los vecinos de menores ingresos y al reforzamiento de la cohesión social, al hacer evidentes elementos transversales de pertenencia a un proyecto social común. Esto se debilita cuando la distancia social es demasiado grande, y en casos con historial de violencia.

    Full Text Available Foi analisada a viabilidade dos manejos de ninhos utilizados pelo Projeto Tamar-Ibama, para a esp écie Dermochelys coriacea nas temporadas reprodutivas entre 1989/90 e 1998/99. Este estudo foi realizado no litoral norte do Estado do Espírito Santo. As desovas foram manejadas de três diferentes formas: mantidas In Situ, transferidas para locais na praia e, ainda, para cercados de incubação. As análises realizadas mostraram que os ninhos que permaneceram In Situ obtiveram os melhores resultados em termos de percentuais de eclosão e números de embriões. Entre os ninhos transferidos, os que foram para os cercados de incubação geraram maior número de filhotes vivos e reduzido número de embriões grandes e pequenos. O único fator que não foi influenciado pela transferência dos ovos, foi o número de natimortos. Foi encontrada diferença significativa no tempo de incubação dos ninhos entre os manejos aplicados. É sugerida a manutenção de uma maior quantidade de ninhos In Situ, e, a criação de Unidades de Conservação em áreas com pouco desenvolvimento urbano e alta concentração de desovas. The analysis was made to compare the viability of the management of nests utilized by Projeto Tamar-Ibama, for the species Dermochelys coriacea in the nesting seasons between 1989/90 and 1998/99. This study was made in northern Espírito Santo. The clutches were managed in three different ways: kept In Situ, translocated to beaches, or to hatcheries. The analyzes showed that In Situ nests had the best results in terms of hatching success and number of embryos. Among the translocated nests, those that went to the hatcheries reached the best results in numbers of hatchlings and small and medium embryos. The only factor that was not influenced by the translocation was the number of piped embryos. A significant difference was found between the hatching period and management used. It is suggested to keep the nest in their natural places (In Situ as much as possible and the implement of the natural reserves where there is little urban development and a high number of clutches.

Para tanto, compara-se o contexto sociocultural da década de 1980 com o do início do século XXI. Com esse intuito, o corpus da pesquisa são os romances sentimentais da editora Nova Cultural e da Harlequin Books, distribuídos atualmente no Brasil tanto pela mídia impressa como pela internet. A análise possibilita verificar as estratégias de abordagem da temática desde o surgimento dos primeiros romances desta espécie no Brasil, em 1978, até o “encontro digital” das apreciadoras desse tipo de literatura na web, bem como suas implicações na cultura contemporânea que busca o desejo de “viver junto” o amor. Palavras-chave: Amor; cultura contemporânea; romances sentimentais; web. ABSTRACT This text aims to verify the similarities and differences in the use of loverelated themes in order to observe the changes in representations and meanings of love to women. To do so the 1980’s sociocultural context is compared to its correspondent in the early 21st century. With this goal, the research’s core are the sentimental romance books from Nova Cultural publishing house and Harlequin Books, available in Brazil both in print and through the Internet. The analysis enables the verification of the theme approach strategies since their first publication in Brazil, in 1978, up to the “digital gathering” of fans of such literature on the web, as well as their implications in today´s culture which endeavors to “live love together”.

    2001-07-01

    The generation expansion-planning problem is a non-linear large-scale optimisation problem, which is even larger when it refers to the Brazilian system, and when one considers the multiple intervening uncertainty sources. To handle the complexity of the problem, decomposition schemes have been used. Usually, such schemes divide the expansion problem into two sub-problems: one related to the construction of new plants (investment sub-problem) and another dealing with the task of operating the system (operation sub-problem). This thesis proposes a genetic algorithm to solve the investment sub-problem. Initially, an analysis of the state of the art on the generation expansion planning and the field of the genetic algorithms are presented. Then follows a practical application of the proposed algorithm in a model of generation expansion planning under uncertainty. Finally, the results obtained in two case studies are presented and analysed. These results indicate that the proposed genetic algorithm is an effective alternative to the solution of the investment sub-problem. (author)

    Brazil has a large potential to install distributed generation systems, using natural gas or renewable like solar, wind or biomass energy. Regarding urban centers, natural gas fired cogeneration and other distributed energy technologies find economical applications. Cogeneration is defined as the generation of two kinds of useful energy from a single energy source. Usually, electrical energy and thermal energy as steam or hot water are produced. By using the absorption refrigeration cycle, chilled water can also be produced to be used in air conditioned systems, often called tri generation, a good alternative to industries, commercial buildings, shopping centers, hospitals, schools and universities. Micro turbines find utilization whenever natural gas is available, but not electricity, like gas compression installations, unmanned platforms or remote production fields. Fuel cells are used in systems requiring high levels of reliability or wherever the non availability cost is high. This paper describe technical and economical data related to PETROBRAS Research Center (CENPES) 3,200 kW electric energy and 1,000 RT chilled water cogeneration system, 200 kW fuel cell and 30 kW and 60 kW microturbines.

    This article presents the impact of distributed generation in studies of voltage sags caused by faults in the electrical system. We simulated short-circuit-to-ground in 62 lines of 230, 138, 69 and 13.8 kV that are part of the electrical system of the city of Goiania, of Goias state . For each fault position was monitored the bus voltage of 380 V in an industrial consumer sensitive to such sags. Were inserted different levels of GD near the consumer. The simulations of a short circuit, with the monitoring bar 380 V, were performed again. A study using stochastic simulation Monte Carlo (SMC) was performed to obtain, at each level of GD, the probability curves and sags of the probability density and its voltage class. With these curves were obtained the average number of sags according to each class, that the consumer bar may be submitted annually. The simulations were performed using the Program Analysis of Simultaneous Faults - ANAFAS. In order to overcome the intrinsic limitations of the methods of simulation of this program and allow data entry via windows, a computational tool was developed in Java language. Data processing was done using the MATLAB software.

    Climate changes taking place on Earth have a strong component due to energy, from the exploitation of primary sources and its conversion to end use forms. The overheating of the atmosphere is consequence of the increasing of greenhouse gases concentration with distinction to carbon dioxide - CO{sub 2}. Brazilian energy sector uses renewable sources with a intensity higher than the world average. The restructuring of the power sector adapting it to a competitive market might contribute to increase the use of fossil in the energy matrix - specially coal and natural gas. The development of thermal power generation technologies from fossil fuels supposes the adaptation to attend environmental patterns of CO{sub 2} emission rates. The improvement of the processes of thermal conversion of these fuels may, in midterm make economically feasible even the use of renewable sources such as biomass. The anticipation in the use of more efficient and advanced technologies has the characteristics of technical intervention and regulatory measures. This work analyses the effects of these actions and measures in a scenery with thermal power expansion in Brazil and estimates the amount of carbon dioxide emissions to a possible result to be achieved with anticipation of new technologies of thermal power using coal and natural gas.

    The development and operation planning of the Brazilian generation system has been realized in a coordinate way by several years, due to some organizations, where the main generating companies from the country take part. The benefit share of the system to each participant of the planning and integrated operation has aroused interest. This paper describes the alternate forms of cost benefit allocation, between the participant companies of a coordinate operation, in order to reach an adequateness of remuneration and incentives. It was analysed two proposal of benefit allocation for energy export/import contracts: share by generation value and share by marginal benefit, concluding that the second one represents the best way of contribution for the several factors that comprising a hydroelectric power plant (storage capacity, effective storage and turbine capacity).

    The production of radiogenic heat in the terrestrial crust is due mainly to U, Th and K presents in the rocks. In this work, we use the gamma-ray spectrometry technique to determine the contents of these elements in drill cuttings and obtaining profiles of heat production rates in oils wells of the Reconcavo basin. In the total, we measure 640 samples of drill cuttings from wells FFL-1 and MGP-34 ceded by PETROBRAS. The thorium contents vary from 1.6 to 25.5 ppm, the uranium contents varied from 0.5 to 5.82 ppm, the potassium samples varied from 0.05 to 2.25 % and the production rates of radiogenic heat varied among 0.50 to 10.85 10{sup -4} {mu}W kg{sup -1}. With the profiles heat production rates obtained, a correlation was verified among these rates and the lithologies at wells FFL-1 and MGP-34. These values will be used in the correlation between these samples at wells and the sample collected at blooming. (author)

    The present work aims to model numerically the generation and propagation of waves in a reservoir, represented by a two-dimensional impermeable box, with a flat horizontal bottom and two vertical walls. The horizontal or vertical harmonic motion is imposed at the container, which is partially filled with water, with two possible initial conditions for the free surface: still water or a stationary sinusoidal wave. Two numerical methods are employed in the solution of the boundary value problem. The first is based on solving an integral equation that arises from Cauchy's integral theorem for functions of a complex variable. The transient nonlinear free surface flow is simulated using a boundary integral method. Numerical results are validated by comparing them with classical analytical solutions. The second method uses the commercial code ANSYS CFX with its homogeneous free surface model. In this case, results are compared with experiments done by Bredmose et al. (2003). In both models, interesting features at the free surface are obtained and discussed. (author)

    This paper presents a methodology of investment analysis in power plants using the Real Option Theory. Particularly, the investment opportunity of a hydro plant is valued based on the energy that will be traded at the new energy auction using the Brazilian Development Bank - BNDES financing program for the Generation of electric energy (new energy). Since this kind of project involves a multistage investment consisting of design, construction and operation phases, it can be treated as a sequential compound option. A binomial approach was elaborated to model this investment opportunity analysis. This approach models the uncertainties in setting up the cash flow for the investments and incorporates some possible managerial flexibility associated with the decision taken along the investment forecast. The proposed methodology will be described in parallel with an example of a real hydro-plant in which we incorporated the flexibilities regarding the decision to invest in each step of the project and an build phase abandon option, representing the transfer of concession rights after the auction.

    This work presents an overview of the characterization physical-chemistry and energy of the aca pit used as input in process of generation of electricity through gasification. Acai pits analyses were accomplished with relationship to the acai pit drying, energy content, proximate and ultimate analyses, size, TGA experiments, bulk density. It was observed that the acai pit can be used as bioenergy but, it presents a low energy content (16,36 MJ/kg) in relationship that of the ' typical' biomass (21 MJ/kg ) and this is not due to the ash content that is very low (1,15%), but yes, the only composition that resembles each other more the Carbohydrates than to the typical composition of the usual biomass. The average diameter of 10 pits chosen at random was 9.5 mm. The acai pits have an angle of repose of {approx}20 degrees, making them ideal for feeding into gasification and combustion processes.

    This paper studies the efficiency of a fined tube solar collector used in artificial satellites and the relation of this efficiency with the entropy generation in the fin. The mathematical modeling of heat transfer in the collector leads to a non-linear integrodifferential system of equations, which is solved numerically. The solution gives the efficiency, which is presented as function of geometrical and physical characteristics of the collector. It is also shown that a minimum entropy generation in the fins, in a collector, whose characteristics are subjected to constraints, corresponds to an optimum efficiency, that is, an efficiency value advantageous to collector performance.

    This work presents the proposal of a methodology which, by exploring the interaction between generation and transmission systems expansion studies, aims for an Integrated Planning of Power Systems. It intends to emphasize the Integrated Planning importance so as to improve the utilization of the available resources in the electric sector and to reduce the expansion and operational costs. The work describes a procedure to consider explicitly the network for the determination of a generation system construction schedule. It considers that the transmission lines construction costs have a significant weight so that it can modify the initial generation expansion plan with the anticipation of some investments and the postponement of others, decreasing the global expansion costs. The generation and transmission systems expansion is made in an optimal way using a Graph Search Algorithm. Finally the best Integrated Plan is obtained from a final algorithm that generates a sequence of integrated plans from combination of generation and transmission algorithms. These plans are compared from a global cost point of view until a convergence criterion has been satisfied. (author) 18 refs., 5 figs., 28 tabs.

    The multi discipline effects in engineering projects, mainly in those of infrastructure, have extended the borders of research to not only evaluate them of the conventional point of view, economic and technical, but also environmental and social. On the other hand, the investor who traditionally searched alternatives only considering the economic and financial performance currently is taken to analyze also the social and environmental aspects. The model described in this paper is a solution proposal to evaluate the merit of an enterprise of distributed generation of thermal origin, considering the economic, social and environmental aspects, using merit indexes that quantify, directly, economic aspects as capital return tax and operating income eliminates, as well as social factors like the impact in the education, health, income and employment rates and still, it verifies the attendance of the environmental restrictions. The solution presented brings a simple and clear form to attribute a merit degree of aggregate to the alternatives to embed distributed generation, considering the intensity of the subjective social responsibility of the investor. The presented model is an important contribution to stimulate a form to evaluate and to prioritize the multi discipline implementation to a distributed generation enterprise, also being able, to be used as financial index or other incentives of the sort.

    Intervals of potential source rocks were identified and characterized by the analysis and interpretation of total organic carbon (TOC) and Rock-Eval pyrolysis data. The rift section presents the best conditions for hydrocarbon generation, especially in Mariricu formation, that presents high TOC, hydrogen index and type I Kerogen. The drift section possesses low source rock potential, the intervals with best organic matter characteristic (quantity and quality) are represented by thin packages positioned in the superior portion of Regencia and Sao Mateus formation and in the basis of Urucutuca formation. The geochemistry data was integrated, on a regional scale, into the thermal maturation and petroleum generation three-dimensional model. Four potentially source rock intervals were simulated, two in the pre-salt section and two in the post-salt section. The results point out that the pre-salt intervals have reached thermal maturity in the proximal shelf and were overmatured in deep water. The thermal evolution obtained for the post-salt zone was very similar to those obtained for the rift section (pre-salt section). (author)

    In order to update and improve the knowledge of the tectonic-sedimentary evolution of Cumuruxatiba's petroleum systems, and also to call the attention of the petroleum companies, the National Agency of Oil, Gas and Biofuels (ANP) signed contract with COPPE / UFRJ for carrying out an extensive project of basin analysis. This paper presents the results of the integration geochemical data and three-dimensional maturation and petroleum generation modeling, on a regional scale. The results present an important progress in understanding the dynamic of the petroleum system in the area, and may be used as a basis for more consistent evaluation of the oil and gas potential and also of the exploitation risk at Cumuraxatiba basin. Three potential source rock intervals were simulated in the 3D model. Two intervals have been defined in the pre-salt zone, at the upper and basal portions of the rift section, and an interval at the post-salt section, at the top of Regencia formation/ basis of Urucutuca formation. The results point out that there is a significant oil and gas potential in deep-water regions and in the south portion of the continental shelf. (author)

    Biogas production through anaerobic bio digestion represents an important breakthrough for the problem of swine waste and energy availability for rural areas. This work aimed to develop a study to estimate the economic viability of a bio integrated system installation and operation to produce electricity from swine wastes. Data for the study were collected in an agroindustry where there are plenty of agricultural activities; however the swine production activity was selected for the anaerobic digestion process because it generates a large amount of waste, with a limited provision in the environment, which characterizes a case study. The analyzed bio digester is a continuous tubular model with brick concrete duct and plastic covering with a gamester, and where the waste of 2,300 fattening pigs are deposited daily. The initial investment estimate for the installation was R$ 51,537.17. The system annual costs were R$ 5.708,20, for maintenance, R$ 4,390.40 for depreciation and R$ 1,366.77 for interests. It was concluded that the bio integrated system would achieve favorable economic results if the energy consumption were to 35 k W per hour a day, in average, where the net present value (NPV) is R$ 9,494.90 and the internal rate of return (IRR) is 9,34% per year.

    The Brazilian electrical system is presenting significant changes in its organizational structure in order to adapt to the new government's policies, market characteristics and the need for expansion of generation systems (supply), transmission and distribution (transport), and commercialization (demand) of energy. The previous structure propitiated the absolute control of the Union in the introduction of new plants, searching for a prioritization to their unit cost of energy, used as an 'Index of Merit' and expressed by U.S. $ / MWh, with planning costs increasing extent. This alternative did not address the environmental issues, referring only those technical aspects and costs of implementation. The socio-environmental issues were relegated to second plan. The significant interest of manufacturers prioritized the {sup b}ig construction{sup ,} as the simultaneous achievement of several big constructions enabling the consolidation of a constant flow of resources and sedimentary longevity of the situation. This paper aims to discuss and present the benefits of distributed generation electric power, with features to complement the offer, but with benefits for micro-regions in which they are deployed, based on technical, economic and socio environmental issues.

    Due to the recent Brazilian electricity crisis, the advantages of the centralized rain dependent generation were put under discussion. The co-generation is an option for the consumer that does not want to be harmed by eventual interruptions in the energy supply and nor to pay higher tariffs during pick load. Besides, the excess of co-generation can be sold for the distribution companies, making possible that the independent producer has profits participating of the electricity power market. The distributed generation provides several benefits, for the fact of being a generation that is located close to the load. Besides, it allows the supply of the growing demand in a fast way, since the construction of big hydroelectric plants, that is the generation model more used in Brazil, is a slow process. With that, the insertion of distributed generation in the Brazilian system tends to become every more common year to year, as it has been happening in other countries. It is noticed, however, that few technical studies on the impacts of the distributed generation in the distribution systems were accomplished to the moment. Problems as over-voltages during light load, impacts on the protection system, and dynamic stability problems, very common in large centralized synchronous machines, can also start to happen in the distribution systems. This article presents a preliminary study on the influence of distributed synchronous generators in the operation of a distribution system. The analyzed technical aspects are: voltage profile, voltage stability, active and reactive power losses, and also critical clearing times for eliminating faults considering different sceneries. The simulations results show which are the main operative restrictions for maximizing the penetration level of distributed generation related with the dynamic and steady-state performance of the electricity distribution system.

    Coal is the fossil fuel with the largest world reserves spread over 70 countries. It is also the main source of power generation in the world accounting for 40% of electric power generation. In Brazil, however, this fuel has an inexpressive share in power generation. In spite of that, national energy security issues, relative low fuel prices and price stability can make this option economically attractive. On the other hand, present environment issues require a search for social and environment responsible solutions, following the sustainable development. Thus, this dissertation's main objective is to present the perspectives of coal power generation in Brazil showing the technologies that seek a reduction of its impacts over the environment as well as an economic evaluation of these options. As it will be shown, coal does not have yet an important paper at the power generation in Brazil in the analyzed horizon due to its characteristics, which can change in a later time. (author)

    The adoption of new technologies for generating electricity is based on technical, economic and environmental analysis. An important factor for choose the technology to be adopted is the raw material available for this purpose. Given the energy application below the potential of agricultural and urban solid waste, the growing demand for energy and the existence of environmental concerns, this thesis aims to emphasize the technology of gasification as an alternative for energy use of agricultural and urban solid waste. Thus, it describes the technology's state of the art, its maturity and improvement. Of great importance for understanding this process, it is needed to add the conclusions derived from experience in the gasification pilot plant at the University of Louvain la Neuve, Belgium. Considering the waste selected, the quantity available and the technology chosen, it is estimated the potential for electric energy that could be generated if the inputs were gasified. (author)

    A new approach for the Scheduling of Hydrothermal Systems, with a formulation that allows the solution of the problem through the linear programming techniques, otherwise the original form, which is complex and difficult is presented. The models were developed through a linear form for the generation function of hydroelectric plants, successive of the linearization of the cost function of the problem. The linear techniques used were the Simplex Method, with some modification that is is efficient, fast and simple. The important physical aspects of the system were preserved, like the individual representation of the hydroelectric plant, the features of cost function with the exponential increase and the head effect. Besides, this formulation can lead to stochastic approaches. All the optimization methods were implemented for the solution of the problem. The performance obtained were compared with each other and with that obtained through the non linear techniques. The algorithms showed to be efficient, with good results and very near to the optimal behavior of the reservoir operation planning obtained by traditional methods. (author)

    With the growing electric energy use demand and almost not expansion of the energy mesh (basically composed by hydroelectric plants) existing in the country, several others methods of alternative energy generation may be necessary. Beyond that, the usually employed energy is becoming much more costly, rarer and politically more impracticable like burn fuels as oil and coal. The use of renewable approaches of energy, that are 'infinite' energies (as the wind and the light of the sun, for example), can become an excellent alternative. In this new energy group, the solar energy transformed by the use of photo voltage cells is becoming very important. The 'clear' solar radiation tends to be a more intelligent and practical option, and the future technology of energy storage will be able to solve the problem of the regions that have less sunny days. Its main advantages on the other alternative sources of energy are the trustworthiness and the previsibility. Its biggest disadvantage consists on the fact that technical limitations can not allow a solar energy generator to distribute electricity for a city. It is interesting to notice that with the development of projects as this in alternative energy, isolated areas that does not access electricity distribution network (as some far regions), it has become the most viable option of generation of electric energy. Another point is that even with the distribution network it has to be checked if it is possible to use this electricity consulting the company credential that work at those localities of consumption. Moreover, many regions of the country already installed the solar energy system for water heating, confirming that, the existing structure allows the installation of a a solar cells generation energy system without many problems. In this project, we introduce a method for electric energy generation by solar cells for rural population of low gains. This option uses low cost materials but with a good quality level. Also presents a comparative table showing a kit for rural areas employment which is constituted of: 3 fluorescent light bulbs (power of 9 W, 3 hours per day, 7 days per week), 1 T.V. of 14' ' (power of 15 W, 3 hours per day, 7 days per week) and 1 Radio (power of 5 W, 6 hours per day, 5 days per week).

    This work presents the proposal of a methodology which, by exploring the interaction between generation and transmission systems expansion studies, aims for an Integrated Planning of Power Systems. It intends to emphasize the Integrated Planning importance so as to improve the utilization of the available resources in the electric sector and to reduce the expansion and operational costs. The work describes a procedure to consider explicitly the network for the determination of a generation system construction schedule. It considers that the transmission lines construction costs have a significant weight so that it can modify the initial generation expansion plan with the anticipation of some investments and the postponement of others, decreasing the global expansion costs. The generation and transmission systems expansion is made in an optimal way using a Graph Search Algorithm. Finally the best Integrated Plan is obtained from a final algorithm that generates a sequence of integrated plans from combination of generation and transmission algorithms. These plans are compared from a global cost point of view until a convergence criterion has been satisfied. (author) 18 refs., 5 figs., 28 tabs.

    Electric energy is an essential component of economical integration of the regions of a country. The operation of an isolated electric system do not admit the adequate rearrangement of the energy flux, mainly in the rush time, which takes to deficit situations in some economical sectors, accentuated by generation options that are not totally compatible with the local reality. This work performs an comparison on the various electric generation options in isolated systems, specially in the Amazon region, based on their local characteristics and generation costs, according to the existent data obtained in the literature or from the electric generation companies.

    In this study, we used data of wind speed, from Universal Records anemograph Fuess, 10 m high, from 19 meteorological stations belonging to the National Institute of Meteorology (INMET), from January 2008 to December 2010. The research objective was to determine the wind power in selected stations. To do so, estimated the parameters of the Weibull distribution, by which it calculated the wind power. The least squares method applied to the frequency distribution of wind speed is a good option for calculating the parameters of Weibull distribution and the estimated parameters c and k, represent satisfactorily, the monthly frequencies of wind speed in the locations studied. The methods in the characterization of wind power in the state of Mato Grosso do Sul, according to the spatial and temporal variability of daily average wind speeds and classification of wind speeds, using the agglomerative Wards at the discretion of inertia, allowed to obtain three homogeneous groups in the study area and the regions that showed higher average daily wind speed was the area of Campo Grande and Sete Quedas.

    The purpose of this study is to gather subsidies for the discussion of the model of expansion in the Brazilian generation sector. This issue, due to its complexity, has brought much controversy. Any expansion may be viable if they met the basic requirements described below: technical feasibility on the specific conditions of the Brazilian energy sector, like the supply of electric power, that is, currently, as the natural competitive advantage of hydraulic origin; financial standards defining that afford resources for the sector expansion in an environment where the characteristics techniques require the need for intensive investment in capital and long-term maturation; provision of guarantees to investors, through contracts for the purchase of energy, in order to reduce the levels of risk in investment and high level of participation and acceptance by all parties involved. The results of the study demonstrate that the natural gas industry development can transformed the natural gas in the primary source of electric power in Brazil, because of the price and the flexibility of the supply.

    The search for sustainable and more rational means of power generation motivates the scientific crew to search for more efficient and cleaner systems. Oil dependence becomes from the kind of development that the humanity had and cannot be dismissed. The question is how to use this source in a more intelligent way. Fuel Cells are electrochemical devices that convert into electric energy the chemical energy from oxi-reduction reactions between a fuel and an oxidant. The current fuel used in a Fuel Cell is hydrogen and oxygen is the oxidant. The great advantage of this device is its efficiency, higher than the one achieved with internal combustion engines. Also Fuel Cells are not limited by Carnot's efficiency. This paper is about the implementation of a distributed generation system using Fuel Cells. Technical aspects are approached together with economical and environmental needs. The already existence of Gas pipelines and the grown production of Natural Gas presented by Brazil turns it into a good market for the implementation of this energy source. The evaluation of this paper shows that is technically possible to use NG in Fuel Cells, mostly in South and Southeast regions, applying the distributed generation of energy concept. The most interesting in a strategic manner is that Brazil already have an indication that it's capable of developing this technology, opening a new market tuning with world's new technological developments. Many research centers develop this technology, not only from the cell composition itself, but also manufacturing techniques. (author)

    The developing process of the Manaus city is questioned from the authors' concern about the built environment and 'destroyed' by the diversity of human actions. Reflecting on the impacts of greenhouse gases in the atmosphere of the city of Manaus by thermoelectric plants, the main source of electricity in the state, the focus of this study is the urban atmosphere where physical and chemical phenomena accelerate the effects of pollution. It is based on two works: A) monitoring of emissions of gaseous pollutants emitted by Power Plant (UTE) Maua from the emission source. This is a project - 'Reducing Emissions of Gaseous Pollutants in Central Steam Power Plants' - conducted by the Interdisciplinary Center for Energy, Environment and Water of the Federal University of Amazonas (UFAM) approved by the Research and Development Program of the Concessionaire local power. B) the result of a Master thesis submitted to UFAM, 'Mapping the distribution of nitrogen dioxide in the city of Manaus' (MARINHO, 2007). This research has made an assessment of levels of distribution of NO{sup 2} in twenty points distributed in a strategic way, demonstrating that the minimum values were found in a region with little urban influence. The analysis of these two works subsidizes a preliminary research in analytical chemistry and attempts to demonstrate the need to advance the search for methods and techniques more consistent. This is an important step toward a policy of environmental management of atmospheric air that will complement future studies of air pollution in the capital of Amazonas. (author)

    This paper presents a model that allows to evaluate the impact of distributed generation (DG) in the expansion of high voltage transmission grid. By applying the model it is possible to determine the size and location of small range generation that can grow incrementally, avoiding or delaying large investments in transmission lines. Whereas the cost of distributed generation for the system is associated with the cost of the incentives offered for that installation, it is also possible to determine the maximum value of this incentive to stimulate the installation of some quantity of DG that postponing the expansion of the transmission grid. The results show the need to consider explicitly the introduction of DG in the expansion planning since the impact it can have on the formation of tariffs for using the transmission system is meaningful.

    The connection of Fuel Cell Power Plants with the utility grid generally needs an electronic power converter for processing the locally generated power and injecting current into the system. Since the source provides a DC voltage, the converter must be able to produce a low-distortion, high-power factor AC current. This paper presents the results obtained with use of a three-phase and a single-phase inverter using low-frequency commutation. An auxiliary circuit is added to the inverter topologies in order to reduce the output voltage distortion, thus improving the current waveform. The main advantages of this approach are the minimization of the switching losses (i.e. high efficiency) and the elimination of the EMI (which avoids high-frequency filters necessary in high-frequency commutation inverters).

    This paper presents the application and use of a methodology based on fuzzy theory and simulates its use in intelligent control of a hybrid system for generating electricity, using solar energy, photovoltaic and wind. When using a fuzzy control system, it reached the point of maximum generation of energy, thus shifting all energy generated from the alternative sources-solar photovoltaic and wind, cargo and / or batteries when its use not immediately. The model uses three variables used for entry, which are: wind speed, solar radiation and loading the bank of batteries. For output variable has to choose which of the batteries of the battery bank is charged. For the simulations of this work is used MATLAB software. In this environment mathematical computational are analyzed and simulated all mathematical modeling, rules and other variables in the system described fuzzy. This model can be used in a system of control of hybrid systems for generating energy, providing the best use of energy sources, sun and wind, so we can extract the maximum energy possible these alternative sources without any prejudice to the environment.

    Air pollution has been a serious public health problem in several countries worldwide. The development process involves the industrialization and consumption, especially electricity. In Brazil, most of this generation comes from hydroelectric dams, supplemented by thermal plants. However, the operation of fossil fuel power plants can result in the emission of air pollutants. The activity of stationary sources added to the mobile source emission (responsible for 90% of air pollution in Sao Paulo) has shown strong and serious associations with health problems. For this reason, the objective of this work was to study the effects that the operation of thermal power plant Piratininga - plant stuck in the metropolitan region in Sao Paulo state - which are essential energy for the region - has on air quality and health of the surrounding population. However, in analyzing the results it was only possible to verify a relationship between respiratory problems and the non-running of the mill. Unfortunately no evidence were found of direct interference of the plant on air quality, however, it was found that air quality in some parts of the metropolitan region in Sao Paulo state hasn't proven to be satisfactory, according to data from CETESB.

    Full Text Available En el presente estudio se identificó la apropiación de los fundamentos y principios filosóficos de la socio-poética en el cuidar/educar. Se analizó el contenido de 19 investigaciones realizadas con ese método, entre 1997 y 2006, por enfermeros y educadores brasileños. Se defiende que la actividad de cuidar/educar es articulada, porque en ella los conocimientos de las personas, profesionales o no, son cuestionados cuando ellos componen el grupo investigador, dispositivo analítico de la socio-poética. Entonces, cada uno le enseña al otro. La socio-poética adhiere a la naturaleza de la enfermería porque cuidar/educar es ayudar las personas a identificar su potencial humano de crecer y fortalecerse como tal. En los resultados obtenidos, se destacan categoría/conceptos acerca de: cuidando en enfermería bajo la perspectiva estética; evaluación en el proceso educativo; humildad al aprender. Se concluye que, al considerar las dimensiones físicas, intelectuales y espirituales en el cuidar/educar, la socio-poética establece un puente para una ecología política del espíritu, consolidando la solidaridad entre los seres humanos.

    Full Text Available Este estudo pretende verificar se, em momentos de crise financeira, há relação entre variações da precificação acionária, estrutura de capital e rentabilidade das empresas estudadas. Trata-se de um estudo de evento, desenvolvido por meio de estatística descritiva, testes de hipóteses não paramétricos e modelagem de equações estruturais. A estrutura de capital não influenciou a variável latente rentabilidade, tendo influenciado apenas a rentabilidade ajustada das empresas estudadas. A variação da precificação acionária foi influenciada pela estrutura de capital e não sofreu influência da rentabilidade das companhias pesquisadas. A hipótese de que as empresas mais rentáveis apresentam menor variação no valor de mercado não foi confirmada. Em síntese, é possível afirmar que as características internas à firma podem explicar parte das variações do valor de mercado. Sugere-se a incorporação de fatores externos à empresa e inerentes à crise, bem como a consideração do “efeito manada” de forma a aprofundar futuros estudos.

No Brasil, cultivares resistentes estão sendo desenvolvidas, mas se a preferência do consumidor não for considerada, o programa de melhoramento pode falhar. Neste trabalho, a aceitabilidade de quatro cultivares resistentes foi acessada no Nordeste brasileiro e comparada a quatro variedades comerciais. Dois grupos de consumidores participaram: adultos jovens e donas de casa. Escala hedônica foi aplicada para aparência externa dos cachos, aceitação global e aceitação por atributos dos frutos (aparência sem a casca, aroma, sabor e textura, além de testes de preferência e intenção de compra. Os dados foram submetidos à ANOVA e Mapa de Preferência Interno. Mulheres e jovens mostraram opiniões semelhantes. As cultivares 'Preciosa' e 'Pacovan Ken' mostraram ser as mais promissoras, sendo que a primeira já pode substituir as cultivares comerciais 'Prata' e 'Pacovan' sem prejudicar a sua aceitabilidade, mas a 'Pacovan Ken' ainda precisa ser melhorada quanto à aparência.The Black Sigatoka Disease is devastating to traditional banana cultivars. In Brazil, resistant cultivars are being developed but if the consumer's preference is not taken into account, the breeding program may not succeed. In this research the acceptability of four resistant cultivars was accessed in the Northeastern Brazilian region and compared to four commercial varieties. Two groups of consumers participated: young adults and housewives. Hedonic scale was applied to external appearance of bunches, global acceptance and acceptance of fruits' attributes (appearance without peel, aroma, flavor and texture. Preference and purchase intent were also evaluated. Data were submitted to ANOVA and Preference Mapping. Women and young adults showed similar opinions. 'Preciosa' and 'Pacovan Ken' cultivars showed to be the most promising ones. 'Preciosa' can already substitute the commercial 'Prata' and 'Pacovan' cultivars without impairing their global acceptability, but 'Pacovan Ken' still needs to be improved regarding its appearance.

    Full Text Available RESUMEN El artículo reflexiona sobre la necesidad de otra aproximación al concepto de habitabilidad que permita aplicar soluciones y propuestas colectivas a todas las escalas, transversal y simultáneamente, de la habitación a la ciudad, reivindicando el valor de lo colectivo como alternativa a la atomización e individualismo imperantes. Frente a aquellas prácticas que o bien se entretienen en la incesante producción de nuevas formas, o bien se alinean con el sistema neoliberal en la tarea de producir y absorber plusvalías a costa de la destrucción creativa del espacio urbano y el territorio, se reclama la urgencia y necesidad de otros modos de hacer que aborden decidida y comprometidamente la tarea de proyectar la convivencia. Es imprescindible avanzar más allá de lo formal y lo tipológico, incorporando no sólo los ya conocidos discursos de adaptación, disociación y otros rituales contemporáneos de lo privado, sino también el proyecto crítico de los espacios comunes, colectivos, públicos e intermedios que fomenten la sociabilidad y convivialidad, y hagan posible el compartir espacios, recursos y vivencias. SUMMARY This paper reflects on the need for another approach to the concept of habitability; for collective solutions and proposals at all scales, transversally and simultaneously, from the room to the city, restoring the value of the collective as an alternative to prevailing fragmentation and individualism. Faced with those practices that are either entertained in the incessant production of new forms, or are aligned with the neoliberal system in the task of producing and absorbing surplus, at the expense of creative destruction of the urban space and the territory, there is an urgent need for other ways to firmly and uncompromisingly approach the task of planning coexistence. It is imperative to move beyond the formal and typological, incorporating not only the well-known rhetoric of adaptation, dissociation and other contemporary rituals of the private, but also the critical planning of those common, collective, public and intermediate spaces that promote sociability and co-existence, and make it possible to share spaces, resources and experiences.

    Full Text Available This paper discusses the role of qualitative approaches in epidemiological studies, beginning with a general discussion of epidemiological and anthropological methods. It focuses on a case study of the health impact of an environmental intervention carried out in Salvador, Bahia State, Brazil. Most of the precedent studies fields, based on primary date, use to devote little attention to the methodological and theorethical questions attached to long-term studies. Four specific aspects of this experience are highlighted: (a drawing up epidemiological study; (b construction of an observational instrument to measure hygiene habits; (c an ethnographic study that was carried out before the epidemiological study; (d observation of the effects of health intervention on health inequalities. Finally, the report details how the findings of qualitative and quantitative studies might be synthesized. It provides a critical overview of follow-up strategies, illustrated with proper examples whenever possible.En este artículo se discute el papel de los enfoques cualitativos en los estudios epidemiológicos, comenzando con una discusión general de ambos métodos.

    PEM (Proton Exchange Membrane) fuel cell uses a simple chemical reaction to combine hydrogen and oxygen into water, producing electric current in the process. It works something like reversed electrolysis: at the anode, hydrogen molecules give up electrons, forming hydrogen ions (this process is made possible by the platinum catalyst). The proton exchange membrane allows protons to flow through, but not electrons. As a result, the hydrogen ions flow directly through the proton exchange membrane to the cathode, while the electrons flow through an external circuit. As they travel to the cathode through the external circuit, the electrons produce electrical current. At the cathode, the electrons and hydrogen ions combine with oxygen to form water. In a fuel cell, hydrogen's natural tendency to oxidize and form water produces electricity and useful work. No pollution is produced and the only byproducts are water and heat. The huge advance on materials development combined with the growth demand of lower impact on environment is placing the fuel cells on the top of the most promising technologies world-wide. They are becoming in medium term feasible alternatives for energy generators up to energy plants of few MW. (author)

    The impacts to wildlife in areas where gas pipelines will be implemented are considerable, changing the existing balance. The main environmental measure adopted in the cases is the deployment of the Fauna Management Programme. This programme is sub - divided into two: Monitoring and Rescue of the fauna. The tracking step starts before the installation of the venture, with the completion of a first in order to identify the impacts before the venture, and finishes two years after the end of the works. These studies are based on guidelines set in the Normative Instruction of the environmental licensor agency, in which the criteria for implementation are restrictive, often without making a license agency distinction of methodology for enterprises with different characteristics. This article intended to review the criteria and the procedures established by the legislation and its real applicability in gas pipeline projects face to the environmental impacts identified to this activity. For this analysis, the methodology used was the case study of two gas pipelines: Cabiunas - Vitoria (GASCAV) and Cacimbas - Catu (GASCAC). The results allowed to conclude that the actions developed to the Sub-Programme of Rescue of the fauna are satisfactory to control environmental impacts and that the Sub-Programme of Monitoring of the fauna just confirm behaviors and information's previous detected.

    The hydrogen, utilized in fuel cells, can be produced from a variety of intermediate chemicals, between them, the ammonia. The ammonia gas as a raw material for the hydrogen production has been used due to its high energetic content, facility of decomposition, high availability, low prices, low storage pressure and its by-products are environmentally correct. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. The residue from the poultry-rearing farms is the broiler litter and from the egg production system is the excreta without any substrate. The characterization of these residues was performed using the wavelength-dispersive X-ray fluorescence (WDXRF), elementary analysis (CHN), thermogravimetry and GC/MS - gas chromatography/ mass spectrometry. The studied factors which influence the ammonia volatilization were: nitrogen content, raising period, urease enzyme, temperature, pH and moisture content. The experiment results with poultry litter and excreta allow to conclude that the manipulation of the following parameters increased the ammonia emission: pH, nitrogen content, raising period, age of birds and excreta accumulation, urease enzyme and the temperature. The addition of different amounts of sand in the excreta and different volumes of water in the poultry litter inhibited the emission of ammonia. The variation of the quantity of material (broiler litter or excreta) and the volume of the flask used as incubator chamber showed no significant alterations to be chosen as a variable. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined in this material. Due to the large amount of poultry litter and excreta from the production processes, the reuse of poultry residues to obtain ammonia is necessary to improve the quality of the local environment. The possibility of ammonia emission increment observed in this study, and its use in a system of ammonia generation - hydrogen production - fuel cell might produce electricity in the enterprise, reducing the expenses of the farms and providing a properly destination for these residues.

    The importance of inter-organisational cooperation within the innovation process has been increasingly recognized. In fact, all organisations, at some point, need to look to external sources for inputs to the process of building up technological competence. In this sense, through a detailed case study, this thesis examine theoretical and empirically how collaborative initiatives have supported the Brazilian nuclear regulatory body in the development and implementation of innovations, in order to verify the positive relationship between the collaboration and the organisational innovation performance. Emphasizing the importance of both internal sources of knowledge and external participation, the study encompasses documentary analysis, a preliminary survey and semi-structured interviews with the regulatory body employers in charge of controlling medical and research facilities and activities involving radiation sources. The thesis demonstrates that innovations developed and implemented in the Brazilian nuclear safety and security area are associated with collaborative initiatives, in order to improve the organizational capability to fulfill safety obligations, providing some important implications for regulatory body managers concerned with the management of innovation. The findings also identified actors with a significant degree of influence in the innovation process. The result reveals that the support provided by these actors has a significant influence on the innovation performance of the Brazilian nuclear regulatory body, suggesting that Brazil should adopt more interactive models of innovation and knowledge transfer. In addition, the findings show that these key actors can play a very distinctive role in the context of sectoral systems of innovation information regime. (author)

    The territorial occupation from the Amazon region is characterized by isolated communities, which makes the conventional electric distribution economically and technically impracticable. To solve the electric problem of these communities, it is necessary for them to produce their own fuel in order to generate electric energy and promote the development. These are the premises that have guided the elaboration of the project PROVEGAM - which has as objective, the installation and performance testing of a conventional diesel engine, adapted to operate with palm oil 'in natura' at the community of Vila Soledade, city of Moju, Para State. Vila Soledade is an isolated community that has, approximately, 700 inhabitants. The PROVEGAM project installed a diesel generator adapted with a conversion kit to operate with 'in natura' palm oil. The operation begins and finishes with diesel oil, in order to heat the palm oil and cleaning possible residues. During the diesel generator installation, diesel oil emissions and performance were compared with the palm oil. Analysing the results, this electric model of generating energy is already recommended to be implemented in others Amazon region communities. (author)

    Renewable energy is all kind of energy produced from a natural source that not diminish because its utilization is 'renewable'. More and more renewable energy resources are used, because they offer multiple advantages such as the energy output facility in small scale and because they are entirely compatible with the environment. The renewable energy used in this project is the photovoltaic solar energy, obtained by the direct conversion of the solar energy in electric energy through the use of solar cells, that can be of several kinds, being the most common of silicon. The main advantage of photovoltaic system is the generation of clean electric energy, or either, generates energy without emitting pollutant and without destroying the environment, moreover is an inexhaustible source of energy. The main disadvantage is, nowadays, the high cost and its low efficiency, so to continue developing it is necessary establish capable mechanisms to make it possible. The search of these mechanisms of incentive becomes-itself a lot important, because the renewable energy and not conventional do not produce a financial return to the investor properly said, but brings lots of benefits to the community, the society and to the environment. This project has the purpose of create an electric energy generation system through solar photovoltaic modules to carry batteries of a motorized wheelchair. An electric wheelchair is moved by electric motors of direct current that are feed by batteries, permitting a medium autonomy of 10 km by load. The batteries are recharged by a battery supplier. This operation should be carried out daily in a space of 6 to 8 hours. According to the Demographic Census realized in 2000 carried out by the IBGE, Brazil has around 1.416.060 physical deficient, which 861.196 are men and 554.864 are women. From a request of a user of electric wheelchair the idea of this project was shown up. The user complained that he stayed a long time carrying his seat and had short time to use it. The goal of this project is analyze the reliability, the efficiency and the costs to implement this system. The main purpose is the increase of the autonomy, the saving of electric energy and to give more freedom to the user. Renewable energy is all kind of energy produced from a natural source that not diminish because its utilization is 'renewable'. More and more renewable energy resources are used, because they offer multiple advantages such as the energy output facility in small scale and because they are entirely compatible with the environment.

    This article presents a brief historical record concerning the Brazilian institutional arrangement given to the Kyoto Protocol and, based on the Brazilian emissions profile, discusses general perspectives to the use of the CDM, mainly in projects involving co-generation in the agricultural sector. It is observed high uncertainty about the liquidity and development of the carbon credit market, above all, with reference to the definition of the second period of the Kyoto Protocol commitments. Even so, with the consolidation of the institutional environment, the carbon credit market must become favorable to the projects of co-generation in agricultural sector, especially in countries as Brazil.

    The externalities related with projects of power generation, the cogeneration in the sugarcane industry including, traditionally are not present in the economic and technical evaluations that support decision making. Such fact implies in a distortion in the evaluation between traditional technologies and the ones based on renewable sources. The Brazilian sugarcane industry presents increasing potential for the participation in the segment of power generation. This study presents partial results from a work group project concerned on research of the externalities associated to the cogeneration using bagasse from sugar cane processing. Externalities are identified from the distributed generation consequences. The possibility of minimizing negative externalities from the sugarcane industry, caused by the production of sugar and alcohol, with positive externalities from the social benefits of distributed generation is the most important conclusion reached as so far.

    The lack of electricity in isolated communities in the Brazilian Amazon has become one of the greatest barrier for the development of the region. Currently, the main technologies that provide electricity to these communities are diesel generators, batteries and dry cells. These non-renewable energy sources may pose serious problems to the environment and human health and have high maintenance and operational costs. Therefore, the search for renewable energy sources, such as water and sunlight, which are highly abundant in the region, has become a great challenge. This thesis presents the studies on application of solar photovoltaic (PV) and fuel cell (FC) technologies to supply electric power in an uninterrupted manner. Outlined are the technical and cost issues of a pilot project set up in an environmentally protected area, next to Bananal island, located in the Southwestern region of the state of Tocantins. The pilot project relies on PV solar power as the primary source of energy for the production of electricity. The surplus energy is stored in the form of hydrogen produced by electrolysis of the water supplied locally, which is reconverted into electric power by fuel cells during periods when there is little or no sunlight. In this context, the aim of the study was to propose a sizing of a hybrid distributed generation system (HDGS), comprised of a PV system, FC and batteries, that optimizes implementation and operational costs, as a potential source of energy for isolated communities in the Amazon. The work was carried out with the help of simulation software HOMER (Hybrid Optimization Model for Electric Renewable) developed by National Renewable Energy Laboratory (NREL). Simulations and a comparative study were carried out of the technologies and potential configurations that meet the needs of these isolated communities. The results showed an optimal solution of HGDS PV-FC batteries with a reduction in the initial cost of the project in about 60% compared to the sizing system only. The HOMER simulated results also indicated that more than 50% of the costs of the PV-FC-battery HDGS regarded the PV system. (author)

    The Brazilian Generator System is predominantly hydroelectric, with some reservoirs having a pluri annual regularization, providing a large storage capacity of potential power for the system. This water storage allows the reduction of the alertly effect from the natural flow over the hydraulic resources for electric power production. Due to this structural characteristic, the main operation problem of the system refers to a strategical determination of storage energy utilization and, consequently, the thermal generation level. This paper examines the theoretical concepts referring to the survey of this operation strategies and analyses the factors for improving. These concepts are also extended for the interconnected electric subsystems case, mainly the interchange effect over the operation strategies of each subsystem. Finally, the natural flow sample influence over the marginal cost is analysed, comparing the obtained values with the historical sample and synthetical series of affluence.

The ammonia gas as a raw material for the hydrogen production has been used due to its high energetic content, facility of decomposition, high availability, low prices, low storage pressure and its by-products are environmentally correct. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. The residue from the poultry-rearing farms is the broiler litter and from the egg production system is the excreta without any substrate. The characterization of these residues was performed using the Wavelength-Dispersive X-Ray Fluorescence (WDXRF), Elementary Analysis (CHN), Thermogravimetry and GC/MS - Gas chromatography/ Mass spectrometry. The studied factors which influence the ammonia volatilization were: nitrogen content, raising period, urease enzyme, temperature, pH and moisture content. The experiment results with poultry litter and excreta allow to conclude that the manipulation of the following parameters increased the ammonia emission: pH, nitrogen content, raising period, age of birds and excreta accumulation, urease enzyme and the temperature. The addition of different amounts of sand in the excreta and different volumes of water in the poultry litter inhibited the emission of ammonia. The variation of the quantity of material (broiler litter or excreta) and the volume of the flask used as incubator chamber showed no significant alterations to be chosen as a variable. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined in this material. Due to the large amount of poultry litter and excreta from the production processes, the reuse of poultry residues to obtain ammonia is necessary to improve the quality of the local environment. The possibility of ammonia emission increment observed in this study, and its use in a system of ammonia generation - hydrogen production - fuel cell might produce electricity in the enterprise, reducing the expenses of the farms and providing a properly destination for these residues.

    This paper presents a methodology for assessing the reliability indices for composite generation and transmission systems based on Support Vector Machines (SVM). The importance of SVMs is its high generalization ability. The SVMs are used to classify data into two distinct classes. These can be named positive and negative. Thus, the basic idea is to classify the system states into success or failure. For this, a pre-classification of states is achieved by performing the proposed SVM-based neural network, where the sampled states during the beginning of the non-sequential Monte Carlo simulation (MCS) are considered as input data for training and validation sets. By adopting this procedure, a large number of states are classified by a simple evaluation of the network, providing significant reductions in computational costs. The proposed methodology is applied to the IEEE Reliability Test System and to the IEEE Modified Reliability Test System. (author)

    This paper describes a line-interactive single-phase to three-phase converter. The typical application is in rural areas supplied by the single-wire with earth return. The traditional objective of feeding a three-phase induction motor is not anymore the main concern for such conversion. Due to the evolution of the agro business, some of the local load (as electronic power converters, computers, communication equipment, etc.) requires high quality power, intended as sinusoidal, symmetrical and balanced three-phase voltage. Additionally, to maximize the power got from the feeder, the system provides a unitary power factor to the feeder. A three-phase PWM converter is used for this purpose. The power converter does not process all the load power, as in the conventional solutions, but only the fraction necessary to regulate the three-phase bus voltage. The control strategy, design highlights and experimental results are presented. (author)

    This paper describes preliminary results obtained with the allothermal ethanol reforming system for synthesis gas (syn-gas) production and hydrogen upgrading and purification for fuel cell applications. The system was designed to supply hydrogen to a 500 W PEM (Proton Exchange Membrane) fuel cell, with an electrical efficiency of 45%, which requires approximately 0.45 m3.h-1 of hydrogen, with a maximum carbon monoxide concentration of 20 {mu}mol.mol-1 (ppm). The study was performed changing the operation temperature and analyzing the resulting syn-gas through gas chromatography for a specific catalyst. This catalyst was tested up to 700 deg C, 1 bar and fixed stoichiometric steam to carbon ratio. The syn-gas, before carbon monoxide shift reactor implementation, was submitted to a two-bed-three-segments purification step composed of chemical and physical molecular sieves for hydrogen purification. The carbon monoxide shift reactor (water gas shift reactor) is under development to improve the efficiency-to-hydrogen and maximize the life of the purification bed. The final results also include a discussion about possible reactions involved in ethanol steam-reforming for such catalyst. (author)

    Utilization of the biogas proceeding from urban solid residues for electricity generation: case study in Sao Paulo. The biogas, generated from organic matter degradation, is composed by a mixture of gases, the main components being carbon dioxide and methane, which is a greenhouse effect gas with global warming potential around 21 times greater when compared to CO{sub 2}. Biogas production is possible from a great variety of organic residues such as urban solid residues, residues from agricultural and livestock activities, swine livestock, sewage mud, among others. The sanitary landfills may count on techniques of capture of the produced biogas and its later burning in flare, where the methane is transformed in CO{sub 2}, minimizing the environmental impact. Besides the opportunity of reducing the environmental damages, biogas can also be used as fuel for generating electricity, thus adding environmental gain and reduction of costs, due to the diminishing of purchase of the energy consumed in the concessionaire. In this context, this article presents the project of utilization of biogas proceeding from urban solid residues for electricity generation and gas illumination, developed by CENBIO. This project is currently in development and the obtained results will provide technical and economic subsidies for its replication. (author)

    This work presents the methodology for analysis of generation/cogeneration projects in NGV filling stations, determining the influence of critical parameters in its technical-economic viability. To achieve this methodology, it was necessary to define parameters that influence directly or indirectly the size of a generating system, as the total electric demand of the filling station, ratio (power of the compressor) / (total installed power), load factor, factor of simultaneity, technical data of major equipment, among others. The methodology has been validated by comparing with data measured in a NGV filling station and allows screening and identifying customers with technical feasibility to evolve in a generation or cogeneration project. The cogeneration with NG generators was highlighted during the analysis of the NGV filling stations and was feasible for establishments which have large thermal demand, as filling stations along the road with large amounts of electric showers in changing rooms.

    Although the Brazilian gas market has been showing steady growth and positive news regarding new discoveries, it is not immune to be questioned about its capacity of value generation, and, in particular, if the new companies, operating in distribution have generated it. Value creation, and its management, has become one of the main activities of the modern corporation in order to align the management and shareholders interests. Despite its advancements, the Brazilian NG industry can be considered at its early stages when compared to those of other countries whose industry is more traditional and mature. The process of unbundling of the gas industry, as well as of the public utilities, has become one of the icons of the Brazilian government policies since the mid 90's. Taking into account regulatory change which had only allowed in the last couple of decades the participation of private ownership into the domestic gas market, a follow up of these companies' performances is of interest. Following the concept of value generation, the present study examines the Brazilian gas distribution sector. Based on a detailed analysis of the financial statements of some of the main companies in the sector, that together represent around 68% of the total Brazilian market, this paper verifies whether the gas distribution sector have presented a positive or negative EVA{sup R}, in other words, if, during the period from 2002 to 2007, these newly companies in the gas industry have created or destroyed value in Brazil.

    In the current context to encourage sustainable development, wind energy plays an important role in the spread of renewable energy sources. In this paper, the possibilities and difficulties of wind power integration in large-scale are evaluated, specifically in the northeastern region of Brazil. From the seasonal complementarity with the water source, scenarios are set out where the maximum participation of only these two sources in the energy supply of the region is sought. Aiming to evaluate the possibilities of a completely sustainable regional energy supply, the northeast subsystem is isolated, excluding, in principle, imports and exports. Therefore, the energy storage capacity of reservoirs in the region is used as a key factor, combined with the seasonal availability of data sources and the annual energy consumption of the region.

    Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more then a decade depending on the magnitude of them. The national power generation group is constituted mainly by hydro power plants complemented by thermal power plants which use several kinds of fuel which generation cost is high, if compared to hydro power generation, and should be minimized. It is a complex planning issue to supply the future power demand which basically depends on the analysis of two compoundable scenarios: the first one refers to the forecast of future economy growing and in this case, unless unpredictable issues occur such as the recent high economy growing experimented by China, the future demand does not show any surprise and is easy to predict; the second one, has inside the uncertainty because the hydro plants productions depends on the water quantity of rivers which depends on the past and current rainfall regimen. The quantity of rainfall is a stochastic data and follows the rules of probability and this drives to the study of cases and its deployments which are numerous causing difficulties to forecast the future. The planning of the electrical area has to examine the future demand and provide the necessary power generation equipment assuming a certain risk. To have it done, simulation models are used to predict the future, combining the two scenarios cited before, and viewing the results promoted by decision took in a step before. The difficult of this task is caused by the big amount of future alternatives provided by the combinatorial phenomena which require, to process the model, a computer with high processing capacity and specialized and specific methods that can resolve this king of problem. Because of the importance and magnitude of this issue, every effort which contributes to the improvement of power planning is welcome and this corroborates with this thesis which has an objective to propose technical, viable and economic solutions to solve the optimization problems with a new approach and has potential to be applied in many others kind of similar problems.

    Three-dimensional modeling is an indispensable tool in manufacturing biomodels. Only after the development of a 3D design can be produced, by rapid prototyping, CNC machining, identical models of the areas of the human body. To perform computational numerical analysis is essential the creation of three-dimensional models. To Custom prostheses the use of the image of the deployment region for the development of customized implant is extremely important because it assists in the process. Only with the 3D design of the deployment region is achieved by testing and improving the designer of the prosthesis with great perfection. In the study presented here was developed a three-dimensional modeling of the jaw of a patient by computed tomography (CT) of the skull of the same . The Invesalius software was used, from the files generated by CT, to create a 3D picture of the skull. This image was exported in STL format for Rhinoceros® software to be cleaned, smoothed and separate the region of interest. After working in Rhinoceros® the image was transformed into a NURBS solid and saved in IGES format. This extension (IGES) was chosen to export the image to the Ansys Workbench® software and thus perform a static structural finite element analysis by applying own forces and fixations of human anatomy. The greatest stress found in the mandible was 213.59 MPa. (author)

    Valuing men and the environment in the developing process is essential due to the main model nowadays, which does not harmonize economical development and environmental preservation, besides wildly exploring the natural resources, degrading the environment and concentrating income, and being socially excluding. There is the need to create a model developed harmonically with the environment, focusing the attention on the social and environmental effects caused by the human activities and on the actions that must be taken aiming at the sustainability, the overcome of the social exclusion, and human development. This essay presents a Case Study focused on the electricity generation in an isolated community, which was developed due to the social and environmental matters. The isolated communities are located on the Brazilian North and Northeast regions, which concentrate most of the Brazilian communities with no access to the electric energy distribution network, which is the electricity supply model in Brazil. The low population density regions, like the Amazon region, present low indices of electrification because of this model, since the extension of the network for attending few consumers, is usually economically and environmentally impracticable. The insertion of an energy source of local occurrence, in this case, residues from the forest activities, will bring environmental benefits associated to the social benefits. The energy generation linked to economic activities will generate jobs and income, besides promoting the fossil fuels substitution, decreasing the CO{sub 2} emissions into the atmosphere and the environmental impact caused by the inadequate disposal of the residues, which are many times, burned in the open skies or disposed on the rivers.

    This work presents an automatic positioning system for photovoltaic panels, in order to improve the conversion of solar energy to electric energy. A prototype with automatic movement was developed, and its efficiency in generating electric energy was compared to another one with the same characteristics, but fixed in space. Preliminary results point to a significant increase in efficiency, obtained from a simplified process of movement, in which sensors are not used to determine the apparent sun's position, but instead of it, the relative Sun-Earth's position equations are used. An innovative movement mechanical system is also presented, using two stepper motors to move the panel along two-axis, but with independent movement, contributing, this way, to save energy during the positioning times. The use of this proposed system in rural areas is suggested. (author)

    In the search of alternatives for sustainable socio-economic development, this study had the objective of evaluating the energetic performance of a concurrent flow biomass gasifier associated with a burner for the gas produced which was of low potential for air heating using a renewable energy source (substituting non-renewable). In this system 4 tests were performed using eucalyptus chips (tests 1 and 2) and logs (tests 3 and 4) as fuel, for the two fan motor frequencies of 60 and 50 hertz. Temperature in the combustion chamber was monitored, along with fuel consumption and other variables. In the tests, the average exhaust air temperature was maintained between 92.7 and 100.4 deg C, and the reduction in the motor frequency from 60 to 50 Hz caused an increase in the duration of the tests. The system presented the best energetic performance when utilizing a frequency of 60 Hz for both fuel types. However, the results of energy efficiency varied very little when comparing tests performed at the same fan frequency. Thus, the gasification process was little affected by variation in the physical characteristics of the tested fuels, and it was recommended that the equipment operate with a frequency of 60 Hz.

    This paper aims to analyze the potential of palm-oil biodiesel production and consumption in remote Amazonian systems (not connected to the national grid), taking into account economic, social and environmental impacts of this biofuel alternative. Through a detailed analysis of remote systems and in particular the examination of the national subside called 'Combustible Consumption Account', the study presents potential scenarios of biodiesel demand for electricity generation in the region, considering also the generation and grid connections projects in forthcoming years. Definition of current and future quantities of biodiesel needed to maintain thermal production in this system defines the Biodiesel investment necessities in remote Amazonian states (Acre, Amapa, Amazonas, Para, Rondonia, Roraima). Possibility of using biodiesel made progress with the launch of the National Program of Production and Use of Biodiesel (PNPB) in 2004. Although African Palm-oil trees adapt very well Amazonian soil, wide adoption of this specie as raw material for biodiesel production shows some barriers, like raise of palm oil price in global market, palm tree long maturation time and attractive price for conventional diesel in the region. Even if using palmoil biodiesel result in obvious significant social and environmental benefits, these benefits tend not to compensate the inefficiency of the market and, thus, expand the biofuel production in the Northern Region.

    The world's concern regarding the reduction atmospheric emissions, due to the global warming, it is a subject that is being quite discussed. A parameter that evaluates the environmental impact considering the emissions of CO{sub 2}, SO{sub x}, NO{sub x} and PM in an integral way and comparing to the international air quality standards that are in force is called ecological efficiency ({epsilon}). This paper intends to compare environmental impacts of the atmospheric pollution due to technologies that use the biomass as fuel with conventional and advanced technologies of electricity generation. It is also evaluated the advantages of the use of the cogeneration starting from the biomass. The most important results that were obtained are comparative graphs confirming that the use of the biomass as energy source is a good option from the ecological point of view, when pollution control methods are used.

    This dissertation presents the development of a mathematical model to be used in the hydrothermal generation expansion planning taking into account uncertainties, the guarantee of energy supply and issues related to the social and environmental problems caused by the power sector. Named 'MELP Ambiental', it is a version of MELP, a model developed by Machado Junior (2000). The environmental valuation was based on results of previous studies. The analysis of the environmental costs scenarios showed that the inclusion of a variable linked to externalities implies in changes on the investment schedule. These changes decrease the total cost (economic and environmental) related to long-term power supply expansion. (author)

    Nowadays, the energy deficit represents one of the biggest governmental challenges, since there is still a great number of communities living in areas without electricity energy; and thus without access to electro-electronic equipment such as television, refrigerators, computers. The main focus of this work is to present the possibility of electricity energy generation in conjunction with the frozen or hot water production in for places without electricity transmission nets or even any type of alternative power plants. The system is based on the standard air cycle called Brayton cycle composed of a turbo-compressor model 4LGZ from BorgWarner, a combustion chamber, a power turbine, a heat exchanger, a water-ammonia chiller, a 5.0 kV A generator, and a command panel for automation and distribution of energy. This system that uses natural gas or LPG, will supply electric energy from the generator, hot water from the heat exchange with the gases of combustion, and water frozen from chiller using as the hot source the gases proceeding from the power system. The prototype is already being tested and the first results obtained are excellent. In this paper, we analyze the internal combustion chamber temperatures. (author)

    Current scenario indicates that renewable energy sources are expected to play an increasingly important role in the world energy matrix, mainly due to a potential reduction of fossil fuel reserves and environment issues. In this context, the use of alternative energy sources, specifically biomass briquettes, shows up as a great opportunity. However, it is known that an economic feasibility assessment for the project depends on decision-making factors such as equipment, labor and material implementation. All costs and investments were calculated. A company headquartered in the city of Tiete, Sao Paulo State, analyzed the total costs of implementing a high density briquette factory. Tow scenarios were considered. In scenario 1, with tax exemption, the Net Present Value (NPV) is positive and the Intern Rate of Return is 16,9%, is an economic feasible scenario. Scenario 2, with no tax exemption, is not economically feasible, the NPV is negative and the Intern Rate Return is 13,9%, lower than 15.0% of the minimum rate of investor attractiveness. (author)

    The hydrogen used in fuel cells can be classified as green or black hydrogen. Ammonia as an hydrogen source has the great advantage of being carbon-free. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. Among the factors which influence the ammonia volatilization, are the pH and the nitrogen content. Poultry litter and excreta isolated were also analyzed, The addition of sodium carbonate, with the rise of pH promoted an increase in the levels of ammonia volatilization. The high nitrogen excreta presented higher ammonia volatilization than the other one. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined int his material. (author)

    The main objective of the effluent treatment is to correct its undesirable characteristics, however, during this process, residues like sludge and biogas are generated, and those residues can be used as raw materials. The PUREFA (Program of Rational Energy Use and Alternative Sources), compound by 14 purposes, is about a project of the USP - University of Sao Paulo, financial backer FINEP - Financier of Studies and Projects. This project had three main objectives: to implant measures of management and action of energy efficiency, to increase the distributed generation in the USP from the renewable resource and not conventional energy and to introduce incentive permanent politics to the efficient and rational use of energy. In the context, the Brazilian Reference Center on Biomass was responsible for two purposes, related to the biogas use for electricity generation. The first purpose had main objective to implant the generation system, to capture and to stock the biogas, produced by biodigestor in the Technological Hydraulically Center (CTH - USP). The biodigestor is a UASB (Upflow Anaerobic Sludge Blanket), whose outflow of the biogas produce is near 4 m{sup 3}/day, opera rates 24 hours per day and utilize the sewer from the residential buildings located in Sao Paulo University, inside the campus. For the biogas utilization, was made its outflow, chemical composition and heat value identifications, parameters that allowed to determinate the real potential for generation and to shown the necessity of the previous treatment, as H2S removal. Finished this stage, was started the next purpose, regarding biogas used as fuel for electricity generation using a generator group Otto cycle. Nowadays this project is a demonstrative project. In this article the technical and environmental project results obtained will be presented. (author)

    The pulp/paper segment is enclosed enters the most energointensive of the industrial sector. Its industries generate great part of the energy that consume from by-products of the process, but still are not self-sufficient. On the other hand, the difficulties of the industrial sector to the availability energy guarantee are well known, due to lack of trustworthiness of the electricity transmission and distribution. In this context, the increase of the self generation of electricity in the segment's plants certainly would go to collaborate for bigger flexibility in the Brazilian energy matrix, not only for the option of Demand Side Management, but even for the possibility of electricity excesses generation, as it is considered in this study. Thus, this work presents an economic and technique analysis of the energy cogeneration and the generation of electricity excesses in the pulp and paper segment and cellulose using more efficient technologies (although in development), as the black liquor gasification. The perspectives for the use of black liquor gasification systems and coupling of this unit to a gas turbine (BLGCC) are studied, with exploitation of the exhaustion gases in cogeneration systems. One is about technology in development phase in the industrialized countries and that it allows high conversion efficiency. They are, also, calculated the excesses generation costs, by means of the thermo economy, on the basis of the exergy concept, the most adjusted methodology to analyze cogeneration processes. Despite the biggest efficiency, the exceeding electricity, in some of the studied configurations, presented generation costs that do not reveal competitive with the sale's price of electricity, defined for the PROINFA, leaving evident the necessity of other mechanisms that make possible the implementation of new technologies, as the incorporation of the external factors and the carbon credits discouragement of the generation costs. In the pulp and paper industries, that currently, already demonstrate little interest in generating and/or to commercialize excesses, the problem is more complex. Beyond the technological impediment, therefore the Tomlinson recovery boilers limit the scale of the process (besides being in the end of its useful life in many units) and of the development training period of the black liquor gasification (still not available commercially), it has the raised cost of this technology (new one).

    Full Text Available The purpose of this study was to examine how administration and accounting students evaluate their courses and profession, considering the aspects of value in the services received, the perceived prestige in the profession and identification with the profession. It was done a literature review on value, prestige and identification, and a field study with 337estudantes of two courses in the city of Fortaleza. The data were evaluated through descriptive analysis, analysis of variance and multiple regression analysis. From the results, it is possible to emphasize that: (1 the assessments vary by course, with accounting students perceiving more value than Administration ones; (2 the main factors of influence on the general perception of value were: relationship between price and quality, reputation of the institution, epistemic value and emotional value. The results indicate elements for managers of courses and of educational institutions to better plan the educational process and develop actions to maintain the motivation of students with their course and with his profession.

    TBG - Transportadora Gasoduto Bolivia-Brasil S.A, executes routine maintenance works at the Gas Pipeline Right of Way, seeking its integrity. In the wetlands of Pantanal, near the Paraguay river crossing, the organic-alluvial soil was submitted to the process of subsidence. This process, associated with the river water flow erosion, shrank the soil volume and diminished or extinguished the pipeline land cover. The pipeline was exposed to the environment, and submitted to tension stresses and the risk of low cycle fatigue during the floods. The cathodic protection system also had to be evaluated, specially in the drought. To mitigate the problem, the embankment technique was adopted using sandy soil, reinforced with polyester geo-webs and with woven polipropene geo-textiles. The solution also used geo-webs with soil-cement as protection elements against the degradation of the geo-textiles blankets. Some monitoring works are associated with those interventions: monitoring of cathodic protection; topographical verification of horizontal and vertical displacements of the pipeline; levels of land covering, and rainfalls and flood measurement. The base of the embankment was built with hydraulic transported soil, and at the end consistently supported the gas pipeline. (author)

    Full Text Available Alnus acuminata (Betulaceae is a pioneer tree that dominates mountain riparian forests throughout the eastern Andes. Early studies associated these forests with particular microclimatic conditions along river beds, but they were later linked to the periodical disturbance regime of mountain rivers. To understand the dynamics of these forests, we analysed tree age and spatial arrangement in two plots along Potrero river and another plot along La Horqueta river, Tucumán Province, north west Argentina. Through intensive tree coring and age reconstruction we identified similar-aged tree cohorts with maximum age ranges of eight years. Tree mapping and Moran's I spatial autocorrelation analysis showed that tree cohorts were spatially clumped, and provided further evidence that coetaneous patches of A. acuminata arise from massive regeneration following catastrophic flooding events. We tested the association between cohort initiation dates and regional maximum river discharge records by means of a randomization procedure and found weak evidence that establishment occurs after devastating floods, which eliminate previous vegetation and create bare sites suitable for A. acuminata regeneration. Dates of tree floodscars sampled along Potrero river precede by one year the most recent cohort initiation date and provide further support of this association. Although previous studies found a positive correlation between El Niño events and mean annual precipitation in northwestern Argentina, we did not detect an association between El Niño and annual maximum stream flow for rivers in Tucumán Province. Therefore, factors driving devastating floods and A. acuminata stand initiation require further studyEl aliso (Alnus acuminata, Betulaceae es un árbol pionero que domina bosques riparios de montaña en los Andes orientales. Estudios iniciales atribuyeron la presencia de estos bosques a las típicas condiciones microclimáticas de cauces de ríos, pero luego estos fueron vinculados al régimen periódico de disturbios de ríos de montaña. Para comprender la dinámica de estos bosques, analizamos la estructura de edades y el arreglo espacial de árboles en dos parcelas sobre el río Potrero y otra parcela sobre el río La Horqueta, en la provincia de Tucumán, noroeste argentino. Mediante barrenado intensivo y reconstrucción de edades identificamos cohortes de árboles con un rango máximo de edades de ocho años. El mapeo de árboles y el índice de autocorrelación espacial I de Moran indicaron que las cohortes de árboles estaban agrupadas en espacio, proporcionando evidencia adicional de que los parches coetáneos de A. acuminata resultan de eventos de regeneración masiva luego de crecientes catastróficas. Evaluamos la asociación entre años de inicio de cohortes y registros regionales de descarga máxima de ríos por medio de aleatorizaciones y encontramos evidencia débil de que los establecimientos ocurren luego de crecientes devastadoras que eliminan la vegetación preexistente y originan sitios desnudos propicios para la regeneración del aliso. Las fechas de cicatrices de crecientes en árboles del río Potrero preceden por un año al inicio de la cohorte más reciente y dan respaldo adicional a esta conexión. A pesar de que estudios previos encontraron una correlación positiva entre eventos de El Niño y promedios de precipitación en el noroeste argentino, nuestros datos no revelan una asociación significativa entre El Niño y caudales máximos anuales en ríos de la provincia de Tucumán. Se requieren más estudios para identificar los factores que originan crecientes devastadoras y cohortes de A. acuminata

    The energy reallocation mechanism (ERM) is a compulsory scheme used to reduce the hydrology risk. The aim of this paper is to present a proposed merger of biomass power plants in ERM. This merger will bring great benefits to the power system as a whole in that the generation of biomass is complementary to the system, reducing thus, the hydrological risk and improve safety of supply, but without raising the price of energy, since that the variable cost of production of biomass is very down. Furthermore, biomass has also benefits to be incorporated into the ERM, as it may commercialize energy to a wider range of buyers, not only during the harvest period, but also in the off season, since the ERM 'donate' energy during the period between harvests, reducing the risk of exposure to the spot market.

    The work developed a methodology fuzzy and simulated its use in control of a hybrid system of electric power generation, using solar-photovoltaic and wind energy. Using this control system, we get the point of maximum energy generation and transfer all the energy generated from alternative sources, solar-photovoltaic and wind energy to charge and / or batteries. The model uses three input variables, which are: wind (wind speed), sun (solar radiation) and batteries (charge the battery bank). With these variables, the fuzzy system will play, according to the rules to be described, what is the source of power supply system, which will have priority and how the batteries are loaded. For the simulations regarding the use of fuzzy theory to control, we used the scientific computing environment MATLAB. In this environment have been analyzed and simulated all mathematical modeling, rules and other variables described in the fuzzy system. This model can be applied to implement a control system of hybrid power generation, providing the best use of renewable energy, solar and wind, so that we can extract the maximum possible energy of these alternative sources without compromising the environment.

However, some seasons of the year, the market does not absorb the oil, and CSN is obliged to defray the burning of this oil, to not interrupt the productive process and cause an environmental impact. Because of this situation, we search alternatives for the viable use of this oil inside CSN steel plant, taking care for the security of the processes and the impact to the environment. This paper describes the details of the work and the implantation of the burning of this oil of the ETEO with BPF oil (type of petrochemical oil) as combustible in the boiler 7 of the power plant UG 50 Hz. For the implantation of this project, operational contingencies of security for equipment was prepared . Moreover, the work included chemical analyses of the oil and the conditions of the boiler using this mixing of oils. The reached results demonstrate the total viability of this project and it was proved another alternative of the use of this residue, with reduction of the fuel costs , steam costs and the electric energy generated in the power plant of CSN.

    Mercury (Hg) is a toxic metal applied to a variety of products and processes, representing a risk to the health of occupationally or accidentally exposed subjects. Dental amalgam is a restorative material composed of metallic mercury, which use has been widely debated in the last decades. Due to the dubiety of the studies concerning dental amalgam, many efforts concerning this issue have been conducted. The Tropical Medicine Foundation (Tocantins, Brazil) has recently initiated a study to evaluate the environmental and occupational levels of exposure to mercury in dentistry attendants at public consulting rooms in the city of Araguaina (TO). In collaboration with this study, the laboratory of analysis at IPEN's Chemistry and Environment Center is undertaking the analysis of mercury levels in exposed subjects' urine samples using cold vapor atomic absorption spectrometry. This analysis requires the definition of a methodology capable of generating reliable results. Such methodology can only be implemented after a rigorous validation procedure. As part of this work, a series of tests were conducted in order to confirm the suitability of the selected methodology and to assert that the laboratory addresses all requirements needed for a successful implementation of the methodology. The following parameters were considered in order to test the method’s performance: detection and quantitation limits, selectivity, sensitivity, linearity, accuracy and precision. The assays were carried out with certified reference material, which assures the traceability of the results. Taking into account the estimated parameters, the method can be considered suitable for the afore mentioned purpose. The mercury concentration found for the reference material was of (95,12 ± 11,70)μg.L{sup -1} with a recovery rate of 97%. The method was also applied to 39 urine samples, six of which (15%) showing urinary mercury levels above the normal limit of 10μg.L{sup −1}. The obtained results fall into a range of concentration from 1,02 to 23,36μg.L{sup −1}. (author)

    To design, modify, and expand surface facilities is a multidisciplinary task which involves substantial financial resources. It can take months or years to complete, depending on the size and level of detail of the project. Nowadays, the use of Next Generation Reservoir Simulators (NGRS) is the most sophisticated and reliable way of obtaining field performance evaluation since they can couple surface and subsurface equations, thus eliminating the need of lengthy multiphase flow tables. Furthermore, coupling a NGRS with an optimizer is the best way to accomplish a large number of simulation runs on the search for optimized solutions when facilities are being modified and/or expanded. The suggested workflow is applied to a synthetic field which reproduces typical Brazilian offshore deep water scenarios. Hundreds of coupled simulation runs were performed and the results show that it is possible to find optimal diameters for the production lines as well as the ideal location for the production / injection platform.

    With the increasing of energetic demand in several production sectors, the search for renewable energy sources which do not cause negative environmental impacts has become more and more relevant. Amongst all the important factors to decide for installing isolated generation systems as renewable sources or diesel and taking the distribution network to isolated communities, it should be considered the economic viability of those benefits. This study aimed to analyse the hybrid solar wind system installed in an isolated community, in Jalapao - TO. Three scenarios were analyzed: first of them, getting the capital back with MRI = 6% per year; second one, getting the capital back with MRI = 0; and third, without getting the investment back. In all the three cases, O and M costs were considered. The proceeds were calculated from the production at the communities workshop, in which the electricity was available. The results indicated that this technology is economically viable if the generated energy is used for production process. It also demonstrated that the third scenario is more interesting for the community, since the contribution per family is only 8% of its incomes. (author)

    Fuel cell based power generation systems have been pointing as promising technology for stationary applications mainly to supply power to critical loads. Among several types of fuel cells the Polymer Electrolyte Membrane Fuel Cells (PEMFC) are the main type used around the world. Nowadays reformers are widely employed to produce hydrogen for fuel cells. The Fuel Cell Laboratory of CEPEL has a power plant based on a 5 kW PEMFC and a natural gas reformer. For a long time the PEMFC was inoperable due to reformer malfunctioning and during this time the full power availability of PEMFC was lost due to deactivation of its catalytic sites. In most cases this deactivation is reversible. So it was started a reactivation process aiming to recover the full operational condition of the PEMFC unit. During this process the gas flow relationship and efficiency of the reformer were studied. An analysis of the PEMFC reactivation was conducted where it was noted that the reactivation took place as expected. During the reactivation process the PEMFC and the whole system efficiency were analyzed. The results suggest that the PEMFC can reach efficiency compatible with conventional power generation systems thus allowing PEMFC technology to compete with these energy sources in point of efficiency.

    In recent years, research activities regarding the global environmental impacts of carbon dioxide (CO{sub 2}) emissions have been intensified. The carbon market aims to minimize the emissions of this dangerous gas as it allows incentives for developed and developing countries to be stimulated not to adjust to a high carbon dioxide energy matrix. This work studies the carbon dioxide emissions and capture mass balance in the sugar and alcohol sector. Through a life cycle analysis methodology of surplus electricity production the CO{sub 2} balance is calculated. The results obtained show that 145,3 tons CO{sub 2}/hectare are sequestered during sugarcane cultivation and 111,5 tons CO{sub 2}/hectare are emitted for electricity production, resulting in a viable capture balance scenario of 33,8 tons of carbon dioxide per hectare of plantation in one life cycle of surplus electricity production that is supplied to the electricity distribution companies. The life cycle analysis of the cultivation of sugarcane biomass for surplus electricity production allowed a high value to be obtained for the CO{sub 2} absorption figure. If compared with other forms of electricity generation, the energy produced in sugar mills presents the lowest values of carbon dioxide emissions of all the other forms of electricity production.

In a moment that the look for sustainable development is the law in Brazil, low costs and environmental impact alternatives must be prioritized. By this way, the PAT/IG Project continuous the Viana's (1987) works, that developed all Brazilian theoretical bases for using Pumps Working as Turbine (PAT). Besides that, the application of induction motors operating as induction generators will be evaluated, as the velocity control system of the PAT/IG group will be developed. The existing Boa Esperanca Farm's micro power plant will be rebuild ed, to receive a new generating group formed for a PAT and a IG, that will be used as natural sized test workbench of Itajuba's Federal University. At the ending of the project, there will be enough subsidies to prove, in practice, the feasibility presented in laboratorial tests by PAT/IG groups as conventional turbines replacer in micro powerplants.

    Although great part of the domestic territory is already supplied with electric energy, still there are many regions where the system is precarious or nonexistent, generically called isolated communities. In the majority of the cases these communities are supplied with Diesel oil generators and the substitution of this fuel for available alternative energy in the localities has been object of study of some institutions of research spread throughout the country. Currently, the use of fuel cells has been strongly argued in the generation of electric energy associated with the local energy necessity, from the use of a regional fuel and this is due to the high efficiency of allied energy conversion to the low ambient impacts that this equipment offers. Most of the different types of fuel cells use hydrogen as a fuel to produce electricity, and it is extracted from renewable or non-renewable sources of energy. Then, the article has the objective of comparing in first analysis the energy efficiency and the cost between the two systems: the ones used currently in the great majority of the isolated communities, constituted of a Diesel engine-generator system, with Natural Gas Reformer System/ Purifier of Hydrogen/ Fuel Cell/ and to analyze if such project presents characteristics that qualifies it to get the carbon credits proposed in the Mechanism of Clean Development.

    In some areas in Brazil the great distance of the generating and consuming centers, together with the low consumption of electric energy of these areas, they make unfeasible investments with transmission and distribution. The use of the biomass as fuel in the distributed generation, is low pollutions, it is renewable, besides possessing a low cost when compared to the fossil fuels [Barros, 2003]. By the way the generation distributed through renewable fuels, becomes an attractive solution for generation in distant and isolated areas of the electric system. Inside of this context, this paper proposes the use of a module combustor, biomass-motor Stirling, based on induction generator, applied to isolated areas, such as the north and northeast areas of the Brazil.

    Environmental issues are of great importance when assessing the feasibility and priority installation of new developments in electric power generation. In this sense, fuzzy logic can help define the regions that have favorable characteristics for receiving certain forms of generation. This study sought to order for the State of Sao Paulo, four kinds of generation projects: those using municipal solid waste gasification, those which make use of landfill gas with a change in firing (to reduce emissions), thermoelectric plants (TEPs) to bagasse (with 15% straw) and Small Hydropower (SHP). Such an ordering considered not only the type of generation but also the allocation of projects in the four regions, defined by regional vocations as defined by the State Water Resources Plan (Annex III of the State Law No. 9.034/94): Agriculture, Conservation, In Industrialization and Industrial. As a result, the use of fuzzy sets allowed the creation of a ranking of the alternatives (which totaled 14 possibilities), based exclusively on the degree of interference in air quality resulting from the installation of every form of generation. Such information may help the decision-making governing bodies to establish priorities in order, thereby accelerating the process of installation and operation of projects for generating electricity.

    This work evaluates the electric power potential of the Brazilian sugarcane industry using the biogas produced by vinasse biodigestion in internal combustion engine driven generators. The electric power surplus based on crop 2004/05 ethanol production data is 9,292 TJ/year (2.6 TWh/year), 0.75% of the total electric power consumption in Brazil during the year of 2003. In spite of its considerable potential the determined minimum selling price for its produced energy of R$ 89.98/GJ (R$ 323.92/MWh) is expensive for present Brazilian electric power market price.

    Although Brazil has great potential for photovoltaics (PV), and is particularly privileged by high solar radiation levels, the role of this renewable energy source (RES) at the Brazilian market is still very small, and the current legislation of the electric sector has no incentives for grid-connected PV systems. The high costs and the paradigm that this RES is feasible for grid-connection only for developed countries are the fundamental arguments placed to justify the lack of consideration of PV energy in Brazil. The main aim of this thesis is to develop a guideline to create a reliable legislation and regulation framework for the Brazilian electrical sector towards the implementation of a widespread grid-connected PV roofs program, and to show a grid parity analysis between conventional generation and PV generation. It also demonstrates the benefits of grid-connected PV systems and it presents the bottlenecks that limit the widespread adoption of PV energy at the Brazilian electrical sector mix. The proposed mechanism to be applied in Brazil is based on the German program (Feed-in Law) and it is analyzed under different scenarios. With this study, it is possible to make an economic viability analysis of grid-connected PV in Brazil, to identify the most suitable PV roof program size for the beginning of the program, and the consequent impacts on tariffs, through the dilution of these costs for the residential energy consumer. The grid-parity analysis shows that from 2015 and 2020 it will be possible to reach grid parity for PV in some regions in Brazil. It is possible that this parity happens even before that time, according to the interest rates applied in Brazil. In this context, it is crucial to create an incentive program to promote PV energy in Brazil, even if current prices are not competitive with conventional generation prices, so that the necessary experience to develop a large scale mechanism could happen with the maximum benefits and in an orderly way when grid parity arrives.

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students.

Nuestro foco de análisis se centró en discutir el conocimiento que estos estudiantes tenían sobre los temas indicados al inicio y término de la propuesta. Los resultados mostraron una percepción limitada que los estudiantes tienen de su alrededor la cual, sin embargo, se expandió debido a las actividades llevadas a cabo, sobre todo en relación con la Luna. Trabajar con medidas sistemáticas revela el manejo cuidadoso de los datos para que sean comprensibles para los estudiantes, así como el trabajo con las sombras para que comprendan primero como se forman estas para después trabajarlas en Astronomía. Por último, llegamos a la conclusión de que el proceso desarrollado consistió en una etapa inicial de una obra que debe ser profundizado en los años posteriores de la formación de estos estudiantes.

    Full Text Available Vários estudos apontam para a pluralidade dos sistemas de cuidados para lidar com a doença e neles integram o sistema profissional, popular e alternativo (inclui o complementar e o tradicional. Qual a sua configuração particular em cada sistema cultural é a questão norteadora das duas pesquisas efectuadas. O objectivo deste artigo é o de perceber como se lida com a doença mental, analisando os itinerários terapêuticos que se constroem entre sistemas de cuidados plurais, caracterizando em particular o recurso à medicina tradicional. A análise dos dois estudos (um efectuado na região Norte, outro em Lisboa permitiu-nos interpretar essas práticas e problematizar os factores socioculturais que determinam e explicam as configurações encontradas. Ambas as pesquisas se enquadram numa metodologia qualitativa. Centrámos a pesquisa na análise dos discursos que obtivemos através de entrevistas semidiretivas, descrevendo-os, interpretando-os e comparando-os. Os resultados apontam para uma pluralidade de itinerários terapêuticos, que se tecem em torno de discursos públicos e privados, onde os sistemas explicativos do recurso à medicina ou às práticas tradicionais encontram sentidos, também eles plurais. As pessoas podem recorrer a estes sistemas de formas diversas, usando um só ou combinando mais do que um, de modo simultâneo ou sequencial, conforme o contexto e as necessidades sentidas face à doença ou ao sofrimento mental. É no espaço de impotência e "incompetência" da medicina "sábia" que se desenvolvem outros sistemas terapêuticos, que é necessário conhecer, pelos resultados que alcançam e pelo seu poder heurístico de explicação da sociedade e da cultura.Several studies point to the plurality of care systems to deal with illness. They can be organized into professional, popular and alternative systems (the latter includes the complementary and the traditional ones. What the particular setup is in each cultural system is the core question of both the empirical studies we report. The purpose of this article is to understand how lay people deal with mental illness, examining the therapeutic itineraries that are constructed between plural care systems, featuring in particular the use of traditional medicine. The analysis of the two studies (one carried out in the north region and the other in Lisbon allowed us to interpret these practices and discuss the social and cultural factors that determine and explain the settings that were found. Both researches fit into a qualitative methodology. In-depth, semi-structured interviews were performed and were analyzed using discourse analysis to describe and interpret data. The results point to a plurality of therapeutic itineraries, built around public and private speeches, where the explanatory systems underlying the use of official medicine and/or traditional practices found plural meanings. People may use these systems in several forms, using one or combining more than one, simultaneously or sequentially, depending on the context and on the needs they feel to face both illness and mental suffering. It is in between the space of the impotence and 'incompetence' of the 'wise' medicine that other therapeutic systems develop. It is important to understand those systems because of their achievements and their heuristic power to explain society and culture.

    Full Text Available En el contexto de la pregunta por el destino de la Teoría Crítica, la discusión entre Axel Honneth y Jürgen Habermas sobre el cambio en el paradigma de la Filosofía Política y Social con la tesis "de la comunicación al reconocimiento" gira aquí en torno a una reconstrucción crítica de la filosofía de Immanuel Kant, un Kant ´moderado´ en un modelo ´explicativo´ o ´hermenéutico´, y así ´irrebasable´ del progreso moral, rompiendo su sistema, y un Kant ´destrascendentalizado´, apto para fundamentar la necesidad de un diálogo entre la razón y la fe. ¿Por qué Kant y no Georg Hegel, central este último para los dos filósofos alemanes en su superación de las aporías de la primera generación de la Teoría Crítica? Pero ¿dónde queda Karl Marx, tan importante para los fundadores de la Escuela de Frankfurt? Y ¿no había exigido Habermas en 2009 con motivo del aniversario de su discípulo, que Honneth, después de su viaje de Marx a Hegel, hiciera el necesario regreso? De tal manera que en esta vuelta, Honneth trajera en su equipaje lo rescatado del Idealismo Alemán. Así la historia de la Teoría Crítica queda inconclusa.In the context of the question for the fate of the Critical Theory, the debate between Axel Honneth and Jürgen Habermas on the change in the paradigm of Social and Political Philosophy with the thesis "from communication to recognition" here revolves around a critical reconstruction of Immanuel Kant’s philosophy, a ‘moderated’ Kant in an ‘explanatory’ or ‘hermeneutic’ model, and so ‘unsurpassable’ moral progress, breaking his system, and a ‘distranscended’ Kant, suitable to substantiate the need for a dialogue between reason and faith. Why Kant and not Georg Hegel, the latter being central for the two German philosophers in their overcoming of the aporias of the first generation of the Critical Theory? But where it remains Karl Marx, so important to the founders of the Frankfurt School? And in 2009, on the occasion of the anniversary of his disciple, had not Habermas demanded that Honneth, after his journey from Marx to Hegel, made the necessary back? In such a way that in this return, Honneth brought the salvage of German Idealism in his luggage. This way the history of the Critical Theory remains incomplete.

Recent investigations have shown that the fuel made of uranium-based niobium and zirconium alloys reaches the best performance relative to other fuels, e.g. UO 2 . Niobium and Zirconium also increase the corrosion resistance and the mechanical strength of the uranium alloys. By means of electrochemical techniques the corrosion behavior of alloys U 2 . 5 Zr 7.5 Nb and U 3 Zr 9 Nb, developed at CDTN and heat treated in the temperature range of 200 deg C to 600 deg C, was assessed. The effect of the parameters pH and solution aeration was studied as well as the influence of zirconium and niobium alloying elements in the corrosion of uranium. The techniques used were open circuit potential, electrochemical impedance and potentiodynamic anodic polarization at room temperature. The tests were performed in a three-electrode electrochemical cell with Ag/AgCl (3M KCl) as the reference electrode and a platinum plate as the auxiliary electrode. The potentiodynamic polarization curves of uranium and its alloys in acidic solutions showed regions with anodic currents limited by a passive film. The presence of niobium and zirconium contributed for the formation of this film. The impedance data showed the presence of two semicircles in the Bode diagram, indicating the occurrence of two distinct electrochemical processes. The data were fitted to an equivalent circuit model in order to obtain parameters of the electrochemical processes and evaluate the effect of the studied variables. (author)

    Mendes, Renato Paulo dos Santos

    O Douro e um dos maiores rios da Peninsula Iberica, constituindo a maior descarga de agua doce para o Oceano Atlântico na costa noroeste portuguesa. A sua pluma estuarina tem particular relevância na dinâmica costeira e na modulacao de fenomenos biogeoquimicos. Sao objetivos desta dissertacao contribuir para a compreensao dos processos fisicos associados a geracao e propagacao da pluma estuarina do Rio Douro no oceano, assim como para o conhecimento dos seus padroes de dispersao e da forma como estes alteram a hidrologia e a circulacao costeira, considerando os agentes forcadores tipicos deste fenomeno (caudal fluvial, vento e mare) e indices climaticos relevantes. Para concretizacao destes objetivos foram desenvolvidas e aplicadas metodologias inovadoras de processamento de dados de detecao remota, assim como novas implementacoes estuarinas e costeiras de modelos numericos. Atraves de imagens MODIS, otimizadas para o estudo de fenomenos costeiros, efetuou-se uma detecao rigorosa da pluma. Identificou-se uma relacao entre o sinal turbido nLw555 e o caudal, demonstrando-se este produto como um bom proxy para a observacao da pluma no oceano. As escalas temporais e espaciais da pluma foram caraterizadas atraves destas imagens, combinadas com dados de caudal fluvial, mare, vento e precipitacao, e tambem com indices climaticos relevantes. Para compreender a propagacao da pluma e caracterizar a sua dinâmica e impacto na circulacao costeira, foi desenvolvida uma aplicacao 3D de modelos estuarinos e costeiros com malhas aninhadas de resolucao variavel. Definiramse e analisaram-se diferentes cenarios de vento e descarga fluvial. A interacao da pluma do Rio Douro e do Minho foi ainda analisada atraves dos resultados de simulacoes baseadas num evento de inverno. Os compositos turbidos mostraram que a pluma e facilmente detetada quando o caudal e maior que 500 m3 s??1. A descarga fluvial e o vento sao os principais forcadores da sua propagacao, enquanto a mare e apenas

    Safaei, Amir

    O setor da construcao e responsavel por uma grande parte do consumo de energia e emissoes na Uniao Europeia. A Geracao Distribuida (GD) de energia, nomeadamente atraves de sistemas de cogeracao e tecnologias solares, representa um papel importante no futuro energetico deste setor. A otimizacao do funcionamento dos sistemas de cogeracao e uma tarefa complexa, devido as diversas variaveis em jogo, designadamente: os diferentes tipos de necessidades energeticas (eletricidade, aquecimento e arrefecimento), os precos dinamicos dos combustiveis (gas natural) e da eletricidade, e os custos fixos e variaveis dos diferentes sistemas de GD. Tal torna-se mais complexo considerando a natureza flutuante das tecnologias solares termicas e fotovoltaicas. Ao mesmo tempo, a liberalizacao do mercado da eletricidade permite exportar para a rede, a electricidade gerada localmente. Adicionalmente, a operacao estrategica de um sistema de GD deve atender aos quadros politicos nacionais, se tiver como objetivo beneficiar de tais regimes. Alem disso, considerando os elevados impactes ambientais do setor da construcao, qualquer avaliacao energetica de edificios rigorosa deve tambem integrar aspetos ambientais, utilizando uma abordagem de Ciclo de Vida (CV). Uma avaliacao de Ciclo de Vida (ACV) completa de um sistema de GD deve incluir as fases relativas a operacao e construcao do sistema, bem como os impactes associados a producao dos combustiveis. Foram analisadas as emissoes da producao de GN, as quais variam de acordo com a origem, tipo (convencional ou nao-convencional), e estado (na forma de GN Liquefeito (GNL) ou gas). Do mesmo modo, o impacte dos sistemas solares e afetado pela meteorologia e radiacao solar, de acordo com a sua localizacao geografica. Sendo assim, uma avaliacao adequada dos sistemas de GD exige um modelo de ACV adequado a localizacao geografica (Portugal), integrando tambem a producao de combustivel (GN), tendo em conta as suas diferentes fontes de abastecimento.
