25. Bulk-loading Dynamic Metric Acess Methods / Operação de carga-rápida (bulk-loading) em métodos de acesso métricos
The similarity degree between data elements is the primordial factor for information retrieval in databases that handle complex data, such as genetic sequences, time series and multimedia objects (long images, audio, videos, texts). To answer these queries in a reduced time, it is necessary methods that use metrics to evaluate the similarity between elements

26. Efeito do citrato de sildenafil sobre o controle autonômico cardiovascular em ratos normotensos.
Sildenafil citrate (Viagra) is a broadly used agent to treat erectile dysfunction. Several clinical trials, however, have demonstrated that in heart diseased patients in use of organic nitrates, the association with sildenafil could significantly enhance cardiac events risk. The possible mechanisms implicated in this increased risk are not completely

27. Fatores associados à presença de placa bacteriana em oclusais de primeiros molares permanentes em crianças de 6-8 anos.
Dental caries is a chronic disease that follows a process of dental demineralization in the presence of dental plaque. Despite of a decline process in its prevalence, the distribution of the disease became polarized in some groups. This phenomenon can be associated with social conditions of vulnerability and with a bigger incidence in children where the firs

29. DESENVOLVIMENTO E CARACTERIZAÇÃO DE EMPANADO A PARTIR DE CORVINA (Micropogonias furnieri)
The work aimed at the elaboration of breaded fish using the species whitemouth croaker (Micropogonias furnieri). The formulation was chosen through a complete factorial plan 2, with triplicate of the central points varying the wash time of the muscle (0; 15 and 30 seconds), concentration of sodium lactate (0; 0,8 and 1,6%) and of powdered milk (0; 1 and 2%).

30. Study of amazon floodplain water composition using hyperion/EO-1 and field reflectance data for the comprehension of temporal variability of optically active constituents / Estudo da composição das águas da planície amazônica por meio de dados de reflectância do sensor hyperion/EO-1 e de espectrômetro de campo visando a compreensão da variação temporal dos seus constituintes opticamente ativos
Two methodological approaches were evaluated to study the reflectance of optically active constituents using hyperspectral imagery of EO-1 Hyperion orbital sensor: a) Linear Spectral Mixture Model; and b) derivative analysis. Two Hyperion images acquired over an area located upstream of the confluence between the Amazon and the Tapajós rivers were analysed,

31. Behavior of B, Zn, Cu, Mn e Pb in contaminated soil under plant cultivation and organic matter addition for metal toxicity amelioration / Comportamento de B, Zn, Cu, Mn e Pb em solo contaminado sob cultivo de plantas e adição de fontes de matéria orgânica como amenizantes do efeito tóxico
Two pot trials were carried out using a heavy metal accidentally contaminated soil. In the first one it was evaluated the plant absorbing, translocating and accumulating power for zinc, copper, manganese, lead and boron by the following vegetal species: Brassica juncea, Raphunus sativus L., Hybiscus cannabinus and Amaranthus crentus, so they could help in th

32. Strategies for potato breeding for tropical climates. / EstratÃgias para o melhoramento da batata para condiÃÃes tropicais
Potato (Solanum tuberosum L.) breeding for tropical climate is important because most cultivars used in Brazil come from temperate countries, presenting low adaptability under warm climates. In the potato breeding program at Universidade Federal de Lavras (UFLA) there is a project established to search for better ways to improve selection efficiency for thes

33. Ressecção videolaparoscópica de hemangiopericitoma do estômago
In the present case (77 years-old woman), the diagnosis on an extramucosal lesion by endosonography was leiomyoma or schwanoma. Radiological exam of the upper digestive tract with barium and abdominal computed tomography confirmed the site of the lesion at the level of the lesser curvature. The operative technique followed the steps of the laparoscopic parti

34. Compressão externa dos membros inferiores : alternativa de tratamento clinico para claudicação intermitente
This study was conducted to evaluate the effect of the extemal compression ofthe lower limbs (CEM) on the treatment of patients presenting with intermittent claudication due to obstruction of the superficial femoral artery, and measured as maximal walking capacity on a motorized treadmill at four KmIh on a four percent incline. Two groups were studied of mal

36. DETERMINAÇÃO DO VALOR DA CONFIABILIDADE EM SISTEMAS COMPOSTOS DE GERAÇÃO E TRANSMISSÃO / EVALUATION OF RELIABILITY WORTH IN COMPOSITE GENERATION AND TRANSMISSION SYSTEMS
This work presents a new methodology to evaluate reliability índices in composite generation and transmission systems. Through this new approach is possible to achieve an accurate estimate of the reliability worth of power systems. The modeling flexibility and simulation efficiency are basic features of the proposed approach. Moreover, it is introduced a ne
