1. Entropy variation in isothermal fluid flow considering real gas effects
Abstract The present paper concerns on the estimative of the pressure loss and entropy variation in an isothermal fluid flow, considering real gas effects. The 1D formulation is based on the isothermal compressibility module and on the thermal expansion coefficient in order to be applicable for both gas and liquid as pure substances. It is emphasized on the

2. Representação gráfica do tempo : efeito de gráficos na compreensão e retenção dos significados do Present Perfect e do seu contraste com o Simple Past
Este trabalho tem como propósito examinar o efeito da representação gráfica do tempo como meio para facilitar a construção de um esquema mental capaz de acomodar os usos do Present Perfect e de seu contraste com o Simple Past em um módulo de língua inglesa mediado por computador. O Present Perfect constitui-se, reconhecidamente, em um problema para p

4. Autômatos celulares não-uniformes, com conexões não-locais, na classificação de densidade
Cellular automata are discrete dynamical systems composed of simple, locally connected structures (the cells), general in terms of their computational power, and that display complex patterns of behaviour. The purpose of this work was to expand previous studies by Zanon (2006), on non-uniform, one-dimensional cellular automata with nonlocal neighbourhood, in

5. APLICAÇÃO DO MÉTODO DAS DIFERENÇAS FINITAS NO DOMÍNIO DO TEMPO NA ANÁLISE DE COBERTURA EM AMBIENTES INTERIORES / APPLICATION OF FINITE DIFFERENCE TIME DOMAIN IN THE ANALYSIS OF INDOOR COVERAGE
The growing interest in broadband wireless local networks and high trans- mission rates requires an increasingly reliable modeling of radio propagation channels, specially for indoor scenarios. The use of optical methods of elec- tromagnetic field tracking along (ray) trajectories between transmission and observation points, via high-frequency analysis of sc

6. Present perfect: uma questão de aspecto : um estudo sobre o contexto na compreensão da noção de aspecto subjacente ao present perfect simples em inglês.
This study approaches the present perfect simple (PP) in English, a verb structure that does not have a semantic equivalent in Brazilian Portuguese language. This fact brings out teaching and learning issues that one occasionally tries to answer. Frequently taught through out of context sentences and treated in grammar and language teaching books in a fragme

7. A colaboração em díades como facilitadora da aprendizagem de língua estrangeira
A presente pesquisa tem como foco investigar o processo de aprendizagem de inglês como LE em díades. A investigação deste trabalho concentrou-se primordialmente na colaboração veiculada durante as negociações realizadas durante a execução de uma tarefa (dictogloss) pedagógica proativamente preparada pela professora/pesquisadora. O foco lingüísti

8. Regularizations: different prescriptions for identical situations
We present a discussion where the choice of the regularization procedure and the routing for the internal lines momenta are put at the same level of arbitrariness in the analysis of Ward identities involving simple and well-known problems in quantum field theory. They are the complex self-interacting scalar field and two simple models where the scalar-vector

9. A aquisição do Present Perfect: um estudo de caso
Empregando uma abordagem orientada pelo significado e outra orientada pela forma em corpora de redações, entrevistas e role-plays, analisou-se a aquisição do present perfect por dezoito aprendizes brasileiros de inglês como língua estrangeira. Os dados revelaram duas categorias principais de situações, como concebidas pelos aprendizes - pertencentes

10. Characterization of new Schistosoma mansoni microsatellite loci in sequences obtained from public DNA databases and microsatellite enriched genomic libraries
In the last decade microsatellites have become one of the most useful genetic markers used in a large number of organisms due to their abundance and high level of polymorphism. Microsatellites have been used for individual identification, paternity tests, forensic studies and population genetics. Data on microsatellite abundance comes preferentially from mic

11. Black holes and thermodynamics / Buracos negros e termodinâmica
In the present work, we have established the connections between black-hole physics and thermodynamics, searching for similarities and differences between these two branches of physicxs, which might look quite far apart. Such links were first sought for and established during the 1970s, thanks to the pioneering work of S. Hawking and Jacob D. Bekenstein, amo

12. Caracterização de semicondutores III-V : descontinuidades de bandas e poços quanticos
In this work, we present a systematic study of two properties of III-V compounds heterostructures which are of great interest to Semiconductor and Device Physics: band offsets in isotype heterojunctions (HJs) grown by LPE and optical properties of MOVPE grown quantum wells. Using for the first time the technique of electrochemical C-V profiling, we measured
