1. SOLUBILITY OF A NEW ANTIRETROVIRAL DRUG (CRS 74) IN AQUEOUS ETHANOL MIXTURES
Abstract This study concerns a new antiretroviral drug named CRS 74, which has a limited bioavailability because of its low aqueous solubility and dissolution rate. To improve these properties, CRS 74 can be recrystallized by using Liquid Anti-Solvent (LAS) crystallization. Ethanol is chosen as the solvent under study for the molecule and water as the anti-s

2. SIMULATION OF THERMAL DECOMPOSITION OF MINERAL INSULATING OIL
Abstract Dissolved gas analysis (DGA) has been applied for decades as the main predictive maintenance technique for diagnosing incipient faults in power transformers since the decomposition of the mineral insulating oil (MIO) produces gases that remain dissolved in the liquid phase. Nevertheless, the most known diagnostic methods are based on findings of sim

3. Modelos de regressão sobre dados composicionais / Regression model for Compositional data
Compositional data consist of vectors whose components are the proportions of some whole. The problem of estimating the portions $y_1, y_2, \\dots, y_D$ corresponding to the pieces $SE_1, SE_2, \\dots, SE_D$ of some whole $Q$ is often required in several domains of knowledge. The percentages $y_1, y_2, \\dots, y_D$ of votes corresponding to the competitors $

4. Estudo de sistemas multicomponentes no processo de injeção cíclica de vapor
No Nordeste brasileiro existem reservatórios de óleos pesados, nos quais se utiliza a injeção de vapor como método de recuperação. Este processo permite diminuir a viscosidade do óleo, aumentando a sua mobilidade e melhorando o volume de óleo a ser recuperado. A injeção de vapor é um método térmico e ocorre na forma contínua ou cíclica. A inj

5. O ensino da argumentação : o enfoque dos livros didáticos de língua portuguesa no ensino fundamental / The teaching of argumentation : the focus of texbooks on portuguese language in elementary school
The purpose of this study was a investigation on the treatment of argumentative writings in the Portuguese Language Textbooks (LDP), as objects of teaching. Investigations carried out in different collections show that little emphasis has been given to education, in the written form of this type of discourse, especially in the early years of schooling. Among

6. Sequential allocation to balance prognostic factors in a psychiatric clinical trial
OBJECTIVE: This paper aims to describe and discuss a minimization procedure specifically designed for a clinical trial that evaluates treatment efficacy for OCD patients. METHOD: Aitchison's compositional distance was used to calculate vectors for each possibility of allocation in a covariate adaptive method. Two different procedures were designed to allocat

7. O concerto para viola e orquestra de Antonio Borges-Cunha : a obra e uma interpretação / The concert for viola and by Antonio Borges-Cunha : a work and an interpretation
The Concerto for Viola and Orchestra by Antônio Borges-Cunha was composed in 2007 and premiered in the same year in a concert, which featured the author as soloist and the composer as conductor. From the very beginning of the project, there was ample dialogue between composer and soloist as to the nature of the viola and as to the aesthetic concept of the w

8. Percussão e interatividade PRISMA : um modelo de esçao instrumento auto-organizado / Percussion and interactivity PRISMA : a model of a self-organized instrument-space
The contemporary development in technology makes it possible to create models for studying the correlations between stimuli and auditory, visual and spatial sensations. Numerous composers have already created compositional processes to explore these dimensions, but this is still incipient in the context of theoretical studies in music performance. Performers

9. Sedimentary facies and provenance of the Bebedouro Formation, Neoproterozoic (BA) / Fácies sedimentares e proveniência da Formação Bebedouro, Neoproterozóico (BA)
The sedimentary record of Neoproterozoic age has become a major subject of research since the rebirth of the models of extreme glaciation and rapid climatic changes for the period, including the Snowball Earth hypothesis. These models are founded on the identification, in all continents, of Neoproterozoic diamictites directly overlain by carbonates, which ar

10. Modelos de depleção para reservatorios de oleo espumo / Depletion models for foamy oil reservoirs
Fields in Canada and Venezuela, which contain foamy oil reservoirs, have exhibited a primary oil recovery on the order of 10 to 15 % greater than the recovery estimated by black-oil simulators. Besides the high oil recovery, other unusual characteristics have been observed, as low gas-oil ratio and high reservoir pressure maintenance. Such discrepancy betwee

11. Christian representations of Jewish people in Minas de prata, by José de Alencar / Representações cristãs do povo judeu em As minas de prata, de José de Alencar
In this dissertation, it is offered an analysis of the Jewish presence in the historical novel As minas de prata(The Silver Mines), a work from Romantic literature written by José de Alencar setting its plot in Brazils colonial times. As a compositional device, the novel resources to a narrator that dwells from the 17th to the 19th centuries, thus making th

12. A modeling methodology for hierarchical control system and its aplication
Current and future computerized systems and infrastructures are going to be based on the layering of different systems, designed at different times, with different technologies and components and difficult to integrate. Control systems and resource management systems are increasingly employed in such large and heterogeneous environment as a parallel infrastr
