1. Diagnostic Value of D-Dimer and INR in Patients Suspected to Have Prosthetic Valve Dysfunction
ABSTRACT Introduction: Prosthetic valve dysfunction is a potentially critical complication of heart valve replacement. An easy and quickly applicable diagnostic procedure is required for recognizing the prosthetic valve dysfunction. The purpose of this study was to prospectively define the diagnostic value of D-dimer and INR level in predicting prosthetic v

2. Modeling vapor liquid equilibrium of ionic liquids + gas binary systems at high pressure with cubic equations of state
Ionic liquids (IL) have been described as novel environmentally benign solvents because of their remarkable characteristics. Numerous applications of these solvents continue to grow at an exponential rate. In this work, high pressure vapor liquid equilibria for 17 different IL + gas binary systems were modeled at different temperatures with Peng-Robinson (PR

3. Modelagem de equilíbrio líquido-líquido, líquido-vapor e líquido-líquido-vapor para sistemas binários, ternários, quaternários e pseudo-quaternários, envolvendo a produção de biodiesel / Modeling of liquid-liquid, liquid-vapor and liquid-liquid-vapor equilibria for binary, ternary, quarternay and pseudo-quaternary systems involving biodiesel production
The worldwide energy demand increases every year. This demand will reach levels that cannot be supplied by current conventional fossil fuel resources. In this context, biofuels arise as a growing primary source of energy, raising research opportunities and encouraging technology development. An important technical issue related to biofuels development is the

4. Study of epoxy/CNT nanocomposites prepared via dispersion in the hardener
In this study, carboxylated (SWCNT-c) and pristine (SWCNT) single-walled carbon nanotubes were randomly dispersed in a hardener prior to mixing it with an epoxy resin. The influence of several parameters on the dispersion process were investigated. The produced samples were characterized by infrared spectroscopy, differential scanning calorimetry, dilatometr

5. Nova equação cúbica de estado para a predição do equilíbrio líquido-vapor de misturas complexas envolvendo polímeros e óleos
Neste trabalho uma nova equação cúbica de estado é proposta baseada no princípio de superposição temperatura-pressão. A equação trata de novas expressões para a determinação dos termos atrativo e co-volume sem dependência de propriedades críticas, podendo ser aplicada a qualquer forma cúbica. Neste estudo foi associada aos parâmetros da equa

6. A prova no processo penal frente a estratégias da política jurídica: uma abordagem crítica / The proof in criminal proceedings against the strategies of Legal Policy: a critical approach.
This dissertation has as object to analyze aspects of the Brazilian Code of criminal procedure and its correlation with the Beddings of the Legal Politics, in face of the consecrated accusatory system in the Constitution of the Federative Republic of Brazil of 1988 and further sources of basic rights. Throughout the work it was identified that the process of

7. Phase equilibria of oleic, palmitic, stearic, linoleic and linolenic acids in supercritical CO2
The knowledge of the phase equilibrium is one of the most important factors to study the design of separation processes controlled by the equilibrium. Fatty acids are present in high concentration as by-products in vegetable oils but the equilibrium data involving these components is scarce. The objective of this work is the experimental determination of the

8. Simulation of styrene polymerization reactors: kinetic and thermodynamic modeling
A mathematical model for the free radical polymerization of styrene is developed to predict the steady-state and dynamic behavior of a continuous process. Special emphasis is given for the kinetic and thermodynamic models, where the most sensitive parameters were estimated using data from an industrial plant. The thermodynamic model is based on a cubic equat

9. A nova disciplina de sistemas econômicos comparados: uma proposta
The new discipline of comparative economic systems: a proposition. This article offers elements for a reorientation of the subject matter of the discipline " Comparative Economic Systems" with the impact of the fall of the Berlin’s wall. Thus, we argue that in the context of the modern democratic society the political choice between society models occurs i

10. Supercritical CO2 recovery of caffeine from green coffee oil: new experimental solubility data and modeling
The caffeine solubility in supercritical CO2 was studied by assessing the effects of pressure and temperature on the extraction of green coffee oil (GCO). The Peng-Robinson¹ equation of state was used to correlate the solubility of caffeine with a thermodynamic model and two mixing rules were evaluated: the classical mixing rule of van der Waals with two ad

11. Moisture effective diffusivity in porous solid mixtures / Difusividade efetiva de agua em misturas de solidos porosos
Porous solids have been applied in several industrial sectors, mainly as mixture of different solids. The physical characterization as well as the effective diffusivity of these materiaIs are important to the optimization of industrial processes that apply mass transport in porous solids. Investigations about effective diffusivity in solid mixture indicated

12. Estudo de monocamadas fosfolipidicas nanoestruturadas obtidas por LB para aplicações em biossensores
There has been long-standing interest in the physical chemical properties of defined mixtures of cholesterol and phospholipids in monolayer and bilayer membranes. They also provide insight into certain properties of the membranes of animal cells. Even if phospholipids and sphingolipids build up the matrix of cellular membranes, sterols are essential componen
