Ecological aspects of the sandfly fauna (Diptera, Psychodidae) in an American cutaneous leishmaniasis endemic area under the influence of hydroelectric plants in Paranapanema river, State of Paraná, Brazil

INTRODUCTION: An epidemiological study was undertaken to identify determinant factors in the occurrence of American cutaneous leishmaniasis in areas under the influence of hydroelectric plants in Paranapanema river, State of Paraná, Brazil. The ecological aspects of the phlebotomine fauna were investigated. METHODS: Sandflies were sampled with automatic light traps from February 2004 to June 2006 at 25 sites in the urban and rural areas of Itambaracá, and in Porto Almeida and São Joaquim do Pontal. RESULTS: A total of 3,187 sandflies of 15 species were captured. Nyssomyia neivai predominated (34.4%), followed by Pintomyia pessoai (32.6%), Migonemyia migonei (11.6%), Nyssomyia whitmani (8.8%), and Pintomyia fischeri (2.7%), all implicated in the transmission of Leishmania. Males predominated for Ny. neivai, and females for the other vector species, with significant statistical differences (p < 0.001). Nyssomyia neivai, Pi. pessoai, Ny. whitmani, Brumptomyia brumpti, Mg. migonei, and Pi. fischeri presented the highest values for the Standardized Species Abundance Index (SSAI). The highest frequencies and diversities were found in the preserved forest in Porto Almeida, followed by forests with degradation in São Joaquim do Pontal and Vila Rural. CONCLUSIONS: Sandflies were captured in all localities, with the five vectors predominating. Ny. neivai had its highest frequencies in nearby peridomestic environments and Pi. pessoai in areas of preserved forests. The highest SSAI values of Ny. neivai and Pi. pessoai reflect their wider dispersion and higher frequencies compared with other species, which seems to indicate that these two species may be transmitting leishmaniasis in the area.

Regional potential for collaborative implementation of small CHP plants in bioenergy technology

This thesis is a preliminary study targeting South-Eastern Finland. The objective was to find out the financial and functional readiness and willingness of the small and medium-sized enterprises of the region to manufacture and sell distributed bioenergy solutions collaboratively as a business network. In this case these solutions mean small-scale (0.5 - 3 MW) woodchips-operated combined heat and power (CHP) plants. South-Eastern Finland has suffered from a decline in the recent years, mostly due to the problems of the traditionally strong industrial know-how area of the region, the paper industry. Local small and medium-sized companies will have to find new ways to survive the toughening competition. A group of 40 companies from suitable industries were selected and financial and comparative analysis was performed on them. Additionally 19 managing directors of the companies were selected for an interview to find out their views on networking, its requirements, advantages and the general interest in it. The studied companies were found to be generally in fairly good financial condition and in that sense, fit for networking activities. The interviews revealed that the companies were capable of producing all the needed elements for the plants in question, and the managers appeared to be very interested in and have a positive attitude towards such business networks. Thus it can be said that the small and medium-sized companies of the region are capable of and interested in manufacturing small bio-CHP plants as a production network.

Spinning reserve opportunity cost in hydroelectric plants

Starting from the deregulated process of the Electric Sector, there was the need to attribute responsibilities to several agents and to elaborate appropriate forms of remuneration of the services rendered by the same. One of the services of great importance within this new electric sector is the Ancillary Services. Among the various types of Ancillary Services, Spinning Reserve is a service necessary for maintaining the integrity of the transmission system from either generation interruptions or load variations. This paper uses the application of the Economic Dispatch theory with the objective of quantifies the availability of Spinning Reserve supply in hydroelectric plants. The proposed methodology utilizes the generating units as well as their efficiencies so as to attend the total demand with the minimum water discharge. The proposed methodology was tested through the data provided by the Água Vermelha Hydroelectric Power Plant. These tests permitted the opportunity cost valuation to the Spinning Reserve supply in hydroelectric plants. © 2005 IEEE.

Reconstituição das vazões naturais a jusante das pequenas centrais hidrelétricas Rio Bonito e Suíça : Rio Santa Maria da Vitória (ES)

O conhecimento do regime natural de rios é relevante, entre diversas razões, para avaliar o impacto antrópico em bacias hidrográficas. Desta forma, visa criar ferramentas que auxiliem no planejamento eficiente dos recursos hídricos. O rio Santa Maria da Vitória (ES) é crucial para o desenvolvimento socioeconômico da Região Metropolitana da Grande Vitória. Adicionalmente, diversos ecossistemas e comunidades agrícolas dependem deste rio. Sendo a geração de energia elétrica um dos usos mais significativos do rio Santa Maria da Vitória, através das Pequenas Centrais Hidrelétricas Rio Bonito e Suíça, o objetivo principal desta pesquisa foi buscar uma melhor compreensão da influência da operação destes empreendimentos na vazão natural deste rio. Além da análise das séries de vazões e de precipitações medidas em Santa Leopoldina, comparando o período anterior com o posterior à implantação das PCH`s, realizou-se a reconstituição das vazões naturais médias diárias e médias mensais a jusante das PCH`s, através da técnica de extensão MOVE.I (tipo 1) e com o auxílio da série de vazão medida na estação fluviométrica Marechal Floriano, localizada na bacia hidrográfica do rio Jucu. Os resultados obtidos, a partir dos dados monitorados na estação Santa Leopoldina, mostraram uma diminuição nas vazões mínimas com 7, 30 e 90 dias de duração para o período pós-regulado. Ainda, as vazões de permanência Q50, Q90 e Q95 e a vazão média de longa duração reconstituídas são menores que as vazões observadas em Santa Leopoldina. Além da presença das PCH`s, as alterações no uso e cobertura do solo da bacia podem ter influência sobre os resultados encontrados. As vazões em Santa Leopoldina, devido aos horários em que são realizadas as medições, podem não representar de forma confiável as oscilações a jusante das PCH`s. Consequentemente, faz-se necessário um monitoramento contínuo das vazões a jusante desses empreendimentos e recomenda-se que seja realizada uma nova reconstituição das vazões naturais do rio Santa Maria da Vitória, através do balanço hídrico dos reservatórios, utilizando os dados operativos das PCH`s.
