1. Escoamento trifasico vertical vertical de oleos pesados aplicado a elevação artificial / Theree-phase flow of heavy oil for application to artificial lift
The oil companies, by their Exploration and Production departments (E&P), have worldwide sought viable means of recovery and prQduction of heavy oil fields, so as to aggregate and delimit those reserves in order to provide the highest revenues. In this search, the role of elevation and flow is to supply an adequate transport for these oils through lines and

2. Polinização e qualidade de sementes produzidas por Pychotria tenuinervis (Rubiaceae) em fragmentos de Mata Atlantica : efeito da distancia de bordas antropicas e naturais
Spatial and temporal climatic variability among areas may affect the reproductive events of plant and animal populations. Habitat changes or abrupt limits between habitats can affect the interactions between plants and their pollen and seed vectors and lead to a decrease in seed quality because of increased inbreeding. The isolation of forest patches and the

3. Hidrodinamica do escoamento bifasico oleo pesado - agua em um tubo horizontal
Considerados de grande importância na indústria petroleira, os óleos pesados constituem uma grande reserva a ser explotada e produzida. Devido a dificuldades associadas às propriedades do óleo como densidade e viscosidade, tem-se procurado métodos para produzí-lo e transportá-lo de forma econômica. Uma dessas técnicas é o corejIow, que é basicame

4. Reticulocitos imaturos como preditores precoces do sucesso do enxertamento no transplante de medula ossea alogenico e autologo
Introduction: Reticulocyte counts and immature reticulocyte fraction have shown to be adequate in the evaluation of erythropoiesis after bone marrow transplantation (BMT). The purpose of this study was to evaluate reticulocyte parameters by means of flow cytometric reticulocyte counting in a group of patients who had undergone autologous and allogeneic BMT.

5. Estudo experimental do escoamento anular oleo-agua ("core flow") na elevação de oleos ultraviscosos
The increase in importance of heavy oil in the energy scenario makes it viable the exploitation of initially unprofitable reservoirs. This leads to the search of technologies capable to improve the development of heavy oil fields. In view of this scenario the present work proposes a new technology for heavy oil lift by using the core annular flow pattem (sho

6. Determination of characteristic curves of production units making use of system simulation / Determinação de curvas caracteristicas de unidades produtivas utilizando simulação de sistemas
To face increasing competitive pressures, companies still perform their main management functionsmaking use of standard pattem solutions. This occurs mainlywith regard to the activities of Production Planning and Control - PPC. Such solutions are normallyinsensitiveto the relations among operational parameters of the production system, and consequent1y,do no

7. Modelagem bidimensional da injeção de agua em reservatorios heterogeneos
This work studies the application of strearntube theory joined with a two-porosity linear model in heterogeneous reservoirs under injection of a incompressible wetting fluid and the production of a non-wetting fluid. It was considered that the streamlines are fixed and there is no flow between each channel. Gravity was neglected and the imbibition phenomena
