Abstract: O presente estudo relata a preda o de Mahanarva fimbriolata em cópula por um Reduviidae Montina confusa, em posi o de acasalamento. O relato ocorreu no Sistema Agroflorestal (SAF), 10o43’087”S e 62o13’314”W, estabelecido na Esta o Experimental da Comiss o Executiva do Plano da Lavoura Cacaueira (CEPLAC-ESTEX-OP), em Ouro Preto do Oeste – RO. Um M. fimbriolata foi capturado durante a cópula, provavelmente porque nessa condi o o casal ficou menos diligente, o que os tornam mais vulneráveis aos inimigos naturais, porém a fêmea do Reduviidae mostrou-se hábil quanto à busca de alimento, mesmo com o macho permanecendo sobre seu corpo. Acreditase que a fêmea do M. confusa, durante o cortejo ou após fecundada pode investir mais energias na busca de alimentos para atender a demanda biolgica visando assegurar um melhor desempenho reprodutivo, sendo esse o primeiro relato de preda o de M. fimbriolata em cópula por um M. confusa em posi o de acasalamento.

Abstract: introduction: this paper reports, for the first time, the presence of the eratyrus mucronatus species in the state of rondonia, brazil. methods: these specimens were caught by chance in the forest and later they were collected using luminous traps. results: after finding these specimens, the number of the triatominae genera in rondonia rose to four, while its species rose to seven. conclusions: complimentary studies will be conducted in order to allow for clearer understanding the ecology of this arthropod, its possible role in transmitting chagas' disease and its current geographical distribution.

Abstract: introduction: this study analyzed the occurrence and the contamination of triatomines by trypanosomatids in orbignya speciosa (babassu) specimens in the state of rond?nia, brazil, in two different environments (pasture and woods). methods: capture of triatomines on babassus and microscopic search for trypanosomatids in their digestive tube were carried out. results: four hundred ninety-four (494) specimens were captured (rhodnius prolixus and r.robustus), of which 35.6% of the triatomines were positive for trypanosomatids. conclusions: the high index of natural infection along with the abundance of triatomines points out to the necessity to create an epidemiological surveillance system to monitor vector-borne transmission and deepen the studies on the ecology of such vectors in the amazon.

Revista Brasileira de Finan?as , 2006,
Abstract: The objective of this paper was to analyze the risk management of a portfolio composed by Petrobras PN, Telemar PN and Vale do Rio Doce PNA stocks. It was verified if the modeling of Value-at-Risk (VaR) through the place Monte Carlo simulation with volatility of GARCH family is supported by hypothesis of efficient market. The results have shown that the statistic evaluation in inferior to dynamics, evidencing that the dynamic analysis supplies support to the hypothesis of efficient market of the Brazilian share holding market, in opposition of some empirical evidences. Also, it was verified that the GARCH models of volatility is enough to accommodate the variations of the shareholding Brazilian market, since the model is capable to accommodate the great dynamic of the Brazilian market.

Abstract: purpose: to evaluate the prognosis value of preoperative parameters, surgical risk, functional benefits and long-term survival after myocardial revascularization. methods: seventy one patients with coronary artery disease and severe left ventricular dysfunction (left ventricular ejection fraction < 30%) and evaluated the myocardial perfusion by tl-201 scintigraphy were studied before and after myocardial revascularization, during the hospitalar period and 48 months (avarage) of late follow up. results: the early mortality observed was 2,8% and the survival in 5 years 62,8%. the statistical analysis related to the preoperative clinical parameters in all patients were not significant in: a) severity of congestive heart failure (chf) or angina; b) presence of q wave (ekg); c) presence of ischemia (tl-201); d) left ventricular ejection fraction. the statistical analysis related to survivors and no survivors were significant: a) functional class iv of chf; b) presence of left brunch bundle block (lbbb). conclusion: our results show that functional class iv of chf and lbbb were related to bad prognosis and demonstrate the difficulty to establish preoperative clinical parameters of prognosis due to the presence of heterogeneous coronary and myocardial pattern of the ischemic cardiomyopathy. our surgical results confirm that myocardial revascularization is a safe procedure, increases late survival and improves the quality of life of these patients with coronary artery disease and severe left ventricular dysfunction.

Abstract: Esta pesquisa tem por objetivo classificar, a partir das demonstra es financeiras, as Cooperativas de Crédito Singulares do Brasil em níveis de sustentabilidade financeira. Diante disso, foi realizada uma análise Intrassetorial a partir dos dados de 31/12/2007 disponibilizados pelo Banco Central do Brasil. Essa análise se deu a partir de indicadores das estruturas financeiras, dos ativos e das demonstra es de resultados de 1.439 institui es. No desenvolvimento da classifica o, também se utilizou de 31 Demonstra es de Resultados e valores do Ativo e Passivo do ano anterior de liquida o de cooperativas de crédito liquidadas pelo Banco Central entre 2003 e 2006. Foi desenvolvido um índice, denominado de índice de Sustentabilidade Intrassetorial Financeira das Cooperativas de Crédito (ISIF-Créd.), com cinco escalas de classifica o: 1 - Sustentabilidade Precária; 2 - Baixa Sustentabilidade; 3 - Média Sustentabilidade; 4 - Alta Sustentabilidade; e 5 - Excelente Sustentabilidade. Foram levados em considera o para classifica o cinco indicadores, a saber: a-Tamanho; b - Independência Financeira; c - Imobiliza o do Patrim nio Líquido; d - Sobras/Patrim nio Líquido; e e - Autossustentabilidade no Período, considerando seis níveis, sendo um acima do ponto médio e os outros cinco em escalas percentis abaixo do ponto médio intrassetorial. Utilizou-se do software SPSS 15.0 for Windows. Os resultados relacionam 54 cooperativas de crédito como de sustentabilidade precária e 150 como sendo de baixa, sustentabilidade, dentre as que estavam em opera o em 31/12/2007, correspondendo a 3,8% e 10,4% respectivamente das 1.439 cooperativas singulares em atividade. Dentre as 31 liquidadas, 74,2% foram classificadas em baixa sustentabilidade e 19,4%, em média sustentabilidade. A metodologia permite segregar, dentre uma grande popula o, as cooperativas de crédito que devem ser objeto de análise detalhada pelos órg os reguladores.
