13. Feasibility Study through Grid-Connected Photovoltaic Systems in Curitiba
ABSTRACT The increase in energy demand in Brazil encourages the country to increasingly invest in generation of electric energy, where the demand for other renewable sources increases gradually because they have a lower impact on the environment. The use of Grid-Connected Photovoltaic Systems (GCPVS) is a viable solution for the country, since it presents fa

14. Fecundity, embryo size and embryo loss in the estuarine shrimp Salmoneus carvachoi Anker, 2007 (Crustacea: Alpheidae) from a tidal mudflat in northeastern Brazil
Abstract Studies on fecundity and embryo size have been frequently used to infer about the reproductive potential, embryogenesis, and the energy investment in embryo production in crustaceans. These parameters are relevant to the knowledge of life-history and diversity of reproductive strategies developed by this group. This study addressed the embryo produc

15. Application of methodology for the adequacy of the electrical motor's power sizing: permanent and transient analysis
Abstract The suitability of the motive force contributes to the efficient use of electrical energy. On the other hand, the inadequate size of electric motors is directly connected to increased investment and running costs. This article presents the theory and mainly the application of a methodology for the adequacy of the motive power. The research was condu

16. Multi-Criteria Analysis to Prioritize Energy Sources for Ambience in Poultry Production
ABSTRACT This paper intends to outline a model of multi-criteria analysis to pinpoint the most suitable energy source for heating aviaries in poultry broiler production from the point of view of the farmer and under environmental logic. Therefore, the identification of criteria was enabled through an exploratory study in three poultry broiler production unit

17. Fermentation process for production of apple-based kefir vinegar: microbiological, chemical and sensory analysis
Abstract The aim of this study was to develop a kefir apple-based vinegar and evaluate this fermentation process using new methodology with Biospeckle Laser. Brazilian kefir grains were inoculated in apple must for vinegar production. In this study, the microbial community present in kefir, and correspondent vinegar, was investigated using Matrix Assisted La

18. Managing Security in a Zone of Peace: Brazil´s Soft Approach to Regional Governance
Abstract Given Brazil’s regional prevalence, its low, late and soft investment in regional security governance appears puzzling. We approach the puzzle through an analysis of contextual features, institutional overlap and policy networks, especially regarding nuclear energy and the environment. Our findings show that Brazil’s behavior is explained by a c

19. Energy embodiment in Brazilian agriculture: an overview of 23 crops
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a v

20. INVESTORS' ASYMMETRIC VIEWS AND THEIR DECISION TO ENTER BRAZIL'S WIND ENERGY SECTOR
Market players' investment decisions sometimes surprise analysts, especially when projects that are less feasible in financial terms enter first in the market, before more viable projects. One possible explanation is that firms have different expectations concerning the future of the market. In this article we use the Option-Games approach for asymmetric duo

23. MODELLING AND FORECASTING OF ELECTRICITY SPOT PRICES AND APPLICATIONS WITHIN THE CONTEXT OF INVESTMENT UNDER UNCERTAINTY / MODELAGEM E PREVISÃO DE PREÇOS À VISTA DE ENERGIA ELÉTRICA E APLICAÇÕES NO CONTEXTO DE INVESTIMENTOS SOB INCERTEZA
O Setor Elétrico Brasileiro (SEB) passou por uma grande reestruturação, saindo de uma situação de monopólio estatal para uma de desestatização regulamentada. Neste processo, a interação entre os agentes, causada pelas privatizações ocorridas no setor, passou a condicionar a formação dos preços do mercado de energia elétrica e, consequentement

24. Demanda de energia na indústria brasileira: efeitos da eficiência energética / Energy demand of brazilian industry: effects of energy efficiency
The conservation of energy, specifically energy efficiency is gaining importance lately in Brazil and the world due environmental impacts that intensive use of energy generates to the environment and for the fact that the supply of energy, mainly derived from nonrenewable sources, is becoming increasingly scarce. Studies which approach the impacts that effic
