1. Ecologia alimentar da toninha Pontoporia blainvillei (Cetacea) / Feeding ecology of franciscana dolphin Pontoporia blainvillei (Cetacea)
Ecological niche theory is originally based on the assumption that individuals of a species use similar resources and therefore are ecologically equivalents. Under this framework, the niche of the species can be defined in terms of average resource use. However, factors such as quality and quantity of prey resources in the environment, consumer gender, age o

2. The numerical modeling of thermal turbulent wall flows with the classical κ - ε model
The goal of this work is to propose a new methodology to simulate turbulent thermal wall flows using the classical κ - ε model. The focus of this approach is based on the manner used to implement heat flux boundary conditions on the solid walls. In order to explain and to validate this new algorithm, several test cases are presented, testing a great range

3. Mercúrio em peixes Characidae (A. altiparanae) e em sedimentos tropicais (ribeirão Guamium, Piracicaba, SP): uma abordagem biogeoquímica do metal tóxico / Mercury in Characidae fish (A. altiparanae) and tropical sediments (river Guamium, Piracicaba, SP)
Verificou-se a ocorrência dos teores totais e disponíveis de mercúrio nos sedimentos de fundo e em suspensão, e de mercúrio total em amostras de lambari (Astianax altiparanae) capturadas no ribeirão Guamium, bacia do rio Piracicaba, S.P. As concentrações foram correlacionadas aos diferentes usos dos solos limítrofes à bacia; pequena ocupação urba

4. ANÁLISE DA DINÂMICA DA ATENUAÇÃO POR CHUVAS EM REGIÕES TROPICAIS / DYNAMIC ANALYSIS OF RAIN ATTENUATION IN TROPICAL REGIONS
The main effect causing non-availability in radio communication systems operating in frequencies above 10GHz, is the rain attenuation, particularly the heavy convective rain that is predominant in tropical regions. This thesis presents a detailed study and modelling of the dynamics of rain attenuation in terrestrial links and earthspace links, based on data

5. Modelagem geoestatistica de atributos geologicos em reservatorios turbiditicos / Geoestatistical modeling of the geological atributes in turbidites reservoirs
The reservoir characterization model is of fundamental importance for the planning of a strategy production petroleum field. The geological models allow the understanding of the reservoir s spacial and qualitative distribution of its principal heterogeneity. This analysis involves enormous amount of variables due to the complexity of the problem, which gener

6. Estrutura etária e distribuição espacial de Myrcianthes pungens (O. Berg) Legrand (Myrtaceae) em um trecho de mata ciliar do rio da Prata, no município de Jardim, Mato Grosso do Sul
The objective of this study was to evaluate the size structure and spatial distribution model of the arboreal species Myrcianthes pungens (O. Berg) Legrand, (Myrtaceae). This is a climax, shade-tolerant semideciduous species, which is distributed from the states of Mato Grosso do Sul and São Paulo to the northern Uruguai. It is actually classified as a thre

7. Quantitative microfocal radiography accurately detects joint changes in rheumatoid arthritis.
Microfocal radiography, producing x5 magnified images of the wrist and hands with a high spacial resolution (25 microns) in the film, permitted direct measurement of erosion area and joint space width in patients with rheumatoid arthritis. The magnitude of errors relating to direct measurement, repositioning the wrist and hand on successive x ray visits, rep
