13. Infestation of rural houses by Triatoma infestans in the region of Los Llanos (La Rioja, Argentina)
Vectorial transmission of Chagas disease has been strongly reduced in most parts of the Southern Cone countries of South America, except in the Gran Chaco region of Argentina, Bolivia, and Paraguay. Given periodical interruptions of the vector control programmes in the endemic region of the Gran Chaco of Argentina, the vectorial transmission of the disease h

14. Contribuição ao estudo de aerogeradores de velocidade e passo variáveis com gerador duplamente alimentado e sistema de controle difuso / Contribution to the study of fuzzy control applied to variable-speed variable-pitch wind generators with double-fed induction generator
The efficient capture of aeolic-energy occurs by means of three blades turbines with adjustable pitch-angle and angular-speed. The pitch-angle adjustment is utilized to limit the aeolic-energy capture when occur very strong winds and, the angular speed adjustment is utilized to maximize the capture of kinetic energy of weak winds. In this mode of operation t

15. Ecologia de Culex quinquefasciatus e de Culex nigripalpus no Parque Ecológico do Tietê, São Paulo, Brasil / Ecology of Culex quinquefasciatus and Culex nigripalpus at the Parque Ecológico do Tietê, São Paulo, Brasil.
Introduction - Culex quinquefasciatus has high synanthropy, infest human dwellings and is vector of nematoids and arbovirus from endemic areas, respectively, in Brazilian coast and in Central or North America. Culex nigripalpus has average synanthropy and can disperse through the anthropic environment carrying Saint Louis Virus and Equine Encephalitis Virus,

16. Monitoramento vetorial e do vírus dengue, Belo Horizonte, Minas Gerais.
Dengue Virus, agent of dengue fever, depends on the vector Aedes aegypti to complete his classical cycle, man vector man. Dengue epidemics are associated with high rates of infestation by the vector, whose control is the main way of prevention. The aim of the present study was monitoring the vector and the virus through the number of Aedes aegypti eggs colle

17. Triatoma rubrovaria (Blanchard, 1843) (Hemiptera - Reduviidae - Triatominae) IV: bionomic aspects on the vector capacity of nymphs
Triatoma rubrovaria has become the most frequently captured triatomine species since the control of T. infestans in the state of Rio Grande do Sul (RS), Brazil. The aim of this study was to evaluate aspects of the vectorial competence of T. rubrovaria using nymphs raised in laboratory under environmental conditions of temperature and humidity and fed on mice

18. Tratamento coletivo da filariose com dose Ãnica de dietilcarbamazina em residentes de Ãrea endÃmica do Recife, Pernambuco:um estudo antes e depois / Collective treatment for filariasis with first dose dietilcarbamazin in residents of endemic areas of Recife, Pernambuco: a before-after study
In Recife, filariasis is considered endemic since 1950âs decade and remains as one of the major expression residual centers for autochthonous transmission of bancroftian filariasis in Brasil. The collective treatment in medium and high-prevalence areas, as WHO recommended strategy, has been integrated to antivectorial interventions. This study is part of an

19. ESTIMAÇÃO DE VELOCIDADE DO MOTOR COM CONTROLE VETORIAL SEM SENSOR, UTILIZANDO FILTRO ESTENDIDO DE KALMAN COM ESTIMAÇÃO DA COVARIÂNCIA DOS RUÍDOS / MOTOR SPEED ESTIMATION WITH SENSORLESS VECTORIAL CONTROL, EMPLOYING AN EXTENDED KALMAN FILTER WITH ESTIMATION OF THE COVARIANCE OF THE NOISES
This work presents a solution to estimate the induction motor drive speed when a sensorless vectorial control is applied employing an extended Kalman Filter with a secundary filter, innovative, which supply the optimal covariance matrix values of the noise and it permit to work online way.

20. Programa de controle vetorial da doenca de Chagas no Estado do Ceara- 1975 a 2002: historico e avaliacao / Program of vectorial control of the illness of Chagas in the State of Ceara- 1975 the 2002: description and evaluation
O Programa de Controle da Doenca de Chagas (PDCh) foi implantado no Estado do Ceara, em 1975. Os municipios tiveram acompanhamento de captura de triatomineos, inicialmente atraves de um Levantamento Triatominico seguido por virias Avaliacoes em ciclos periodicos entre os anos de 1975 a 2002. Durante esse periodo nao houve nenhuma avaliacao sistematica das at

22. Chagas disease: current epidemiological trends after the interruption of vectorial and transfusional transmission in the Southern Cone countries
Chagas disease, named after Carlos Chagas who first described it in 1909, exists only on the American Continent. It is caused by a parasite, Trypanosoma cruzi, transmitted to humans by blood-sucking triatomine bugs and by blood transfusion. Chagas disease has two successive phases, acute and chronic. The acute phase lasts 6 to 8 weeks. After several years of

23. Triatoma rubrovaria (Blanchard, 1843) (Hemiptera-Reduviidae-Triatominae) III: patterns of feeding, defecation and resistance to starvation
Data from the Chagas Disease Control Program indicate a growing domiciliary and peridomiciliary invasion of Triatoma rubrovaria in the State of Rio Grande do Sul, where it has become the most frequent triatomine species captured there since the control of T. infestans. Bionomic characteristics that could influence the vectorial capacity of T. rubrovaria as v

24. Triatoma rubrovaria (Blanchard, 1843) (Hemiptera, Reduviidae, Triatominae) II: trophic resources and ecological observations of five populations collected in the State of Rio Grande do Sul, Brazil
Triatoma rubrovaria has become the most frequently captured triatomine species after the control of T. infestans in the State of Rio Grande do Sul (RS), Brazil. Isoenzymatic and chromatic studies indicate the existence of, at least, two distinct phenotypic patterns of T. rubrovaria in RS. The geographic variation noted through molecular tools may also result
