Modelagem e simulação de ciclos a gás com resfriamento de ar na entrada

The optimization of energy generation systems has become a key issue for technological and social development, mainly in developing countries, where the electricity consumption rises sharply. Gas turbine cycle is an electricity generating system, which studies have demonstrated that inlet air cooling increases net power and thermal efficiency. Thus, this study intends to quantify these parameters for environments with different ambient temperature and relative humidity. Two types of air cooling were used: evaporative and absorption systems. The configuration parameters only with the gas turbine cycle were compared to those whose configuration allowed cooling. First, it was analyzed only evaporative cooling. Next, the absorption system was used for analysis. The last configuration mixed these two methods, dividing equally its flow. The results showed that thermal efficiency and net power increase in any case of cooling, with absorption system more advantageous in terms of generated energy, where an increase between 1 and 2 MW was observed, depending on the ambient conditions . When the two methods were working together at low relative humidity, it showed a thermal efficiency increase compared to absorption system, up to 2.4%. Evaporative cooling was less effective, but it is a good and cheap possibility to increase the cycle parameters at high temperature and low relative humidity

Nitrogen mass balance in the Brazilian Amazon: an update

The main purpose of this study is to perform a nitrogen budget survey for the entire Brazilian Amazon region. The main inputs of nitrogen to the region are biological nitrogen fixation occurring in tropical forests (7.7 Tg. yr(-1)), and biological nitrogen fixation in agricultural lands mainly due to the cultivation of a large area with soybean, which is an important nitrogen-fixing crop (1.68 Tg. yr(-1)). The input due to the use of N fertilizers (0.48 Tg. yr(-1)) is still incipient compared to the other two inputs mentioned above. The major output flux is the riverine flux, equal to 2.80 Tg. yr(-1) and export related to foodstuff, mainly the transport of soybean and beef to other parts of the country. The continuous population growth and high rate of urbanization may pose new threats to the nitrogen cycle of the region through the burning of fossil fuel and dumping of raw domestic sewage in rivers and streams of the region.

A redescoberta de um sociólogo: considerações sobre a correspondência de Émile Durkheim a Salomon Reinach

O artigo apresenta um balanço das mais recentes descobertas documentais relativas ao sociólogo francês Émile Durkheim, e reflete sobre seu impacto na reavaliação, seja ela histórica e/ou teórico-metodológica, de seu legado. Almeja-se armar o leitor frente à leitura de sua correspondência com Salomon Reinach, enfatizando particularmente o debate sobre o tema do totemismo, que é um dos eixos centrais de As formas elementares da vida religiosa, obra que neste ano completa seu centenário de publicação, e o envolvimento de Durkheim no Caso Dreyfuss, que representa um dos principais aspectos de seu engajamento político.

A Agência Nacional de Saúde Suplementar - ANS: onze anos de regulação dos planos de saúde

Trata-se de um trabalho com objetivo de apresentar os principais resultados alcançados pela regulação dos planos de saúde exercida pela Agência Nacional de Saúde Suplementar, autarquia instituída para promover o equilíbrio das relações entre operadoras e consumidores, tornando o mercado de planos de saúde mais eficiente. Como avanços mais significativos oriundos da regulação do setor podem ser citados: as barreiras à entrada e à saída das operadoras no mercado, a ampliação das coberturas assistenciais contratuais, o monitoramento e o controle dos reajustes, a indução a práticas de promoção da saúde e à qualificação do setor, e a possibilidade da portabilidade de carências. Como desafios a serem enfrentados, podem ser apontados: o monitoramento da qualidade da assistência prestada, a renúncia fiscal, a existência dos cartões de desconto, a operação de empresas como operadoras de planos de saúde sem o registro na ANS e a adoção de alguns mecanismos nocivos de regulação assistencial pelas operadoras de planos de saúde.

SADA and DESYRE DSSs descriptive classification criteria (main issues related to DSS's)

Brownfield rehabilitation is an essential step for sustainable land-use planning and management in the European Union. In brownfield regeneration processes, the legacy contamination plays a significant role, firstly because of the persistent contaminants in soil or groundwater which extends the existing hazards and risks well into the future; and secondly, problems from historical contamination are often more difficult to manage than contamination caused by new activities. Due to the complexity associated with the management of brownfield site rehabilitation, Decision Support Systems (DSSs) have been developed to support problem holders and stakeholders in the decision-making process encompassing all phases of the rehabilitation. This paper presents a comparative study between two DSSs, namely SADA (Spatial Analysis and Decision Assistance) and DESYRE (Decision Support System for the Requalification of Contaminated Sites), with the main objective of showing the benefits of using DSSs to introduce and process data and then to disseminate results to different stakeholders involved in the decision-making process. For this purpose, a former car manufacturing plant located in the Brasov area, Central Romania, contaminated chiefly by heavy metals and total petroleum hydrocarbons, has been selected as a case study to apply the two examined DSSs. Major results presented here concern the analysis of the functionalities of the two DSSs in order to identify similarities, differences and complementarities and, thus, to provide an indication of the most suitable integration options.
