16. Práticas alimentares, efeito do índice glicêmico e da hidratação no desempenho de ciclistas / Dietary practices, effect of the glycemic índex and hydration on performance of cyclists
This dissertation is composed of three studies. First study: the objective was to review the effects of pre-exercise ingestion of high, moderate and low glycemic index (GI) meals on performance. For the first study, was held search in the Medline, Scielo, Science Direct and Pubmed databases. Some studies reveals a positive association between pre-exercise in

17. Análise da composição da dieta de seis espécies de peixes coexistentes em um reservatório tropical (Reservatório de Ribeirão das Lajes, Piraí-RJ) / Analysis of the composition of the diet of six fish species coexisting in a tropical reservoir
The present study analyzed the digestive contents of 221 individuals of six fish species, from Ribeirão das Lajes reservoir (Piraí-RJ). There were 44 specimens of Loricariichthys castaneus, 56 Parauchenipterus striatulus, 46 Metynnis maculatus, 40 Astyanax bimaculatus, 31 Astyanax parahybae and 4 Rhamdia quelen. The aim was to establish their diets, throug

18. Assembly rules in Muscid Fly assemblages in the grasslands Biome of Southern Brazil
The distribution of muscid species (Diptera) in grasslands fragments of southern Brazil was assessed using null models according to three assembly rules: (a) negatively-associated distributions; (b) guild proportionality; and (c) constant body-size ratios. We built presence/absence matrices and calculated the C-score index to test negatively-associated distr

19. Competição no mercado de produtos, governança corporativa e desempenho das companhias / Product market competition, corporate governance and organizational performance
As a pioneer in Brazil, this dissertation investigates how product market competition (PMC) effects on the corporate governance quality. The analysis frame coincides with the period from 2005 to 2007, with a total sample of 90 companies. The research was divided into two interrelated parts. The first one investigates how PMC variables significantly impact th

20. Seed vigor and performance of maize plants in the field / Vigor de sementes e desempenho de plantas na cultura de milho
High physiological potential seeds allow faster seedling emergence and higher plant initial growth than low physiological potential seeds. Within plant populations, the uneven seedling emergence could affect plant competitive ability for resources (light, water and soil nutrients) and have direct effects on plant grain yield and population grain yield. There

21. DESENVOLVIMENTO INICIAL DE UM PLANTIO MISTO DE Eucalyptus urograndis E Acacia mearnsii EM SISTEMA AGROSSILVICULTURAL / INITIAL GROWTH AND PRODUCTIVITY IM MONOSPECIFIC AND MIXED STANDS OF Eucalyptus urograndis AND Acacia mearnsii IN AN AGROFORESTRY SYSTEM
Understanding the initial development in consortiated systems are vital to decide about practices to obtain a sustainable productivity, in relation to environmental resources in an agrossilvicultural site. Due to this, this study had as objective: - to evaluate the agricultural productivity in agroforestry systems with different arrangements of the forest sp

22. MODELAGEM DO INCREMENTO DE ÁRVORES INDIVIDUAIS DE Cedrela odorata L. NA FLORESTA AMAZÔNICA / MODELLING THE INDIVIDUAL TREES INCREMENT OF Cedrela odorata L. IN THE AMAZONIAN FOREST.
The periodic growth in basal area of 62 trees of cedro (Cedrela odorata L.) was reconstructed from 2005 to 2008, by dendrochronological techniques in Porto Acre, AC, to quantify and describe the growth rate by relationship with morfometric variable, competition index, sociological position, crown shape and occurrence of lianas on the crown. Significant diffe

23. Biologia reprodutiva da tainha Mugil liza Valenciennes e do Parati Mugil curema Valencienns (Actinopterygii, Mugilidae) na Baia de Sepetiba, RJ, Brasil
The reproductive biology of the mullets Mugil curema and Mugil liza was determined mainly by observing gonad development, size at maturation and fecundity. The objective of this study was to learn about the strategies developed by these species to maintain their exploited populations in an increasingly altered system. It was hypothesized that there are diffe

24. Avaliação da sucessão ecológica e do desenvolvimento de árvores em uma lavra de cascalho revegetada do Distrito Federal, DF - Brasil
Brazilian savanna holds the greatest floristic biodiversity of this type in the World. 41,6% of brazilian savanna vegetation was substituted by anthropic activities. One of them is mining. The recuperation process of the degraded area is slow and complex and involves revegetation activities and soil management practice. The present study was established in a
