1. AN EOS-BASED NUMERICAL SIMULATION OF THERMAL RECOVERY PROCESS USING UNSTRUCTURED MESHES
Abstract In the past thirty years, the development of compositional reservoir simulators using an equation of state (EOS) has been addressed in the literature. However, the development of compositional thermal simulators in conjunction with the EOS formulation, in particular, has not been addressed extensively. In this work, a fully implicit, thermal, compos

2. An experimental study of the partitioning of trace elements between rutile and silicate melt as a function of oxygen fugacity
Magmas produzidos em zonas de subducção possuem um característico empobrecimento em elementos de elevado potencial de ionização (HFSE) em comparação com outros elementos de incompatibilidade similar. Essa assinatura geoquímica pode ser atribuída a presença do mineral acessório rutilo (TiO2) como fase residual. Dados experimentais obtidos nesse est

3. Saberes psicológicos no Compêndio Narrativo do Peregrino da América (1728), de Nuno Marques Pereira / Psychological Knowledge at Compêndio Narrativo do Peregrino da América (1728), by Nuno Marques Pereira.
It is possible to define conceptions about human kind and psychological knowledge, elaborated by social and cultural context at colonial age in Brazil history. The history of Psychological Knowledge in Brazil has its legacy dated from colonial era. Nowadays, it is possible to analyze that knowledge in order to understand the evolution of the concepts of huma

4. Distribuição ambiental de poluentes orgânicos encontrados em lodos de esgoto.
O objetivo deste trabalho foi apresentar uma modelagem da distribuição ambiental de vinte e nove poluentes orgânicos encontrados em amostras de lodos de esgoto das estações de tratamento de esgoto de Barueri e Suzano, SP. Lodos de esgoto são misturas de produtos orgânicos e inorgânicos gerados nos processos primários e secundários de tratamento que

5. Experimental determination of vapor-liquid equilibrium data of binary mixtures of fatty acids through Differential Scanning Calorimetry / Determinação experimental de dados de equilibrio liquido-vapor de misturas binarias de componentes de oleos vegetais atraves da calorimetria diferencial exploratoria
This work will contribute to some unpublished data of phase equilibria of compounds that form the biodiesel, which arouses the interest immediately. Vapor-liquid equilibrium (VLE) data for three binary mixtures of saturated fatty acids have been successfully measured through differential scanning calorimetry (DSC). These data are of great interest to the ind

6. Avaliação do destino e bioacumulação de benzo(a)pireno através de simulação computacional
The objective of this work was to evaluate the environmental distribution of benzo(a)pirene, a polycyclic aromatic hydrocarbon, by the EQC model. The modeling of the contaminant distribution was accomplished by means of the fugacity model applied to a hypothetical scenario constituted by air, water, soil and sediment. The modeling and simulations revealed th

7. De Horácio a Drummond, o tempo dispara; de Drummond a Horácio, o tempo repara
The purpose of this dissertation is to demonstrate as suggested by the title, that Carlos Drummond de Andrade in his poetry finds in the western Lyrical Poetry tradition some elements and brings them to his poetic works. Considering he was a modern poet and a modernist it was expected he should oppose any past or classical influence. Horace#s works are the s

8. Geologia e petrologia do prospecto GT-34 : evidência de metassomatismo de alta temperatura e baixa fO2, província mineral Carajás, Brasil
The GT-34 Prospect in the Carajás Mineral Province is located within older gneissmigmatite terrains (Xingu Complex). Sulfide mineralization is hosted by irregular bodies of brecciated rocks and/or orthopyroxene-amphibole bearing rocks outcropping among gneissic rocks. Distribution of sulfide-rich intervals form an irregular NE trend of about 1.5 km-long and

9. As relações amorosas pelos "chats" da internet: a solidão na contemporaneidade
The search for love relationships through chat rooms and its feasible association to loneliness its the purpose of this paper. The modern city life predicts by the means of concentrating people in huge buildings or by the ever-growing communication system, like the internet, a constant nearness between humans. However, despite the urban mass and the technica

10. Utilização do conceito de fugacidade na previsão do comportamento ambiental do carbosulfan e do carbofuran na cultura do arroz irrigado
Pesticide use to control pests, diseases and weeds is steadily increasing due to a general food demand increase, cropping area limitation, and manpower availability. Pesticide application without a sound knowledge may hazard environment and human health. Regulatory agencies enforces that, before a new product releasing to the market for agricultural use, int

11. Computational simulation of deodorization and deacidification of vegetable oils. / Simulação computacional de processos de desodorização e desacidificação de oleos vegetais.
This work was developed in order to study through simulation, the processes of deacidification by steam refining and deodorization, present in the vegetable oil industry. The modeling was developed for batch and continuous processes in steady-state and dynamic regime. To describe mass and energy balances, and equilibrium relationships, it was necessary to us

12. Using pervaporation data in the calculation of vapour permeation hollow-fibre modules for aroma recovery
Taking into account the close similarity between pervaporation and vapour permeation techniques, a method for employing pervaporation flux data in the modelling of vapour permeation modules is proposed. It is based on the use of fugacity gradients across the membrane, instead of concentration ones, as the driving force for mass transfer. This procedure is in
