25. Propriedades de equilibrio de sistemas aquosos com acidos policarboxilicos, açucares e sucos de frutas. / Properties of balance of watery systems with acid policarboxilicos, you sweeten and fruit juices.
Polycarboxylic acids are important constituents of coffee extract, fermented milk, fruit juice and tomato paste. Sugars occur extensively in food systems like fruit, honey, milk and vegetable. Polycarboxylic acids and sugars are the main soluble solids in fruit juice. Experimental measurement and estimation of equilibrium properties are of great value in res

26. Abertura comercial e integraÃÃo regional: impactos da ALCA sobre as exportaÃÃes agrÃcolas brasileiras numa abordagem de equilÃbrio parcial
In the last decade of the 20th century, the Brazilian government initiated a policy to liberalize international trade in order to respond to expectation of inserting the country into the context of the globalized economies, also to promote internal stabilization. Simultaneously Brazil took part in regional free trade agreements, seeking the extention of trad

27. Export-oriented brazilian agro-industry: analysis of tariff barriers imposed by United States and European Union / Produtos da agroindústria de exportação brasileira: uma análise das barreiras tarifárias impostas por Estados Unidos e União Européia
A União Européia e os Estados Unidos são os dois maiores importadores e exportadores mundiais de produtos agroindustriais. O Brasil é um dos mais dinâmicos fornecedores mundiais destes produtos. O país detém a terceira posição no ranking dos maiores exportadores mundiais e apresenta, desde 2002, o maior superávit comercial agroindustrial do mundo.

28. AplicaÃÃes de metodologias teÃricas em estudos de QSAR-3D de pirimidinas substituÃdas
The aim of this work is determining a 3D QSAR model for a homologous series of substituted pyrimidines with known anti-inflammatory activities. Previous results from classic QSAR (which include AM1 calculated parameters) have shown the importance of electronic parameters in the successful prediction of a novel and more active compound. The first step was to

29. Dinâmica do grupo de renormalização: Um estudo via equações diferenciais parciais / Dynamic of the group of renormalization : A study via partial differential equations
Consideramos dois tópicos distintos relacionados a modelos clássicos da mecânica estatísticas de equilíbrio. O primeiro constitui-se na análise de equação parabólicas semi-lineares associadas à transformação de grupo de renormalização para o gás de Coulomb hierárquico bidimensional e o gás dipolos hierárquicos em dimensão d>1 após tomarmo

30. Estudo da sintese e hidrolise de acetato de etila em fase gasosa catalisada por enzimas suportadas
Enzymes supported in a solid phase catalyzing reactions with substrates and products in gaseous phase constitute a recent progress in the biotechnology. It has technological applications that include: toxic gas remediation, biosensors and synthesis of pharmaceutical, fragrances and aromas for the food industry and cosmetics. This work presents, the experimen

31. Estrategias numericas para solução de modelos de não-equilibrio para absorção gasosa com reações quimicas complexas (regime estacionario e dinamico)
Gas absorption with chemical reactions is a very common industrial separation processo Until now the traditional equilibrium stage model have been the main tools to the design and unsteady state simulations of the gas-liquid contact equipment. The nonequilibrium model based on mass transfers fundamentais presents a more realistic description of the gas-liqui

32. Considerations on nonequilibrium entropy and temperature
Several aspects of the Thermodynamics of systems away from equilibrium are considered. Particular attention is given to the question of the concepts of entropy and temperature in arbitrary nonequilibrium conditions. Even though such state function and thermodynamic variable are elusive in such conditions, it is elaborated and discussed an approach to them th

33. Equilibrio liquido-liquido em sistemas eletroliticos aquosos
: In this work, the effect of the addition of the salts potassium chloride, potassium sulphate and potassium bromide on the liquid-liquid equilibrium of the ternary system water/ethanol/1-pentanol, was experimentally determined, with a revision of the data collection methodology for the liquid-liquid equilibrium of quaternary systems. The experimental proced

34. Caracterização termodinamica de sistemas ternarios para escolha de processos de separação
The objective of this work is to develop a methodology for studing the vapor-(liquid)-liquid phase behaviour of ternary systems and for rapidly determining the partial miscibility presence by using the commercial simulator PROII. The methodology uses flash simulation to do liquid-(liquid)-vapor equilibrium calculations simulation results are used to generate

35. Efeitos não-lineares em sistemas dissipativos
A non-linear quantum transport theory for many-body systems arbitrarily away from equilibrium is elaborated using Zubarev s non-equilibrium statistical operator method. It is described an iterative method that allows to organize the collision integrals with memory in a series of partial contribution of increasing power in the intensity of the interaction, le

36. Partial molar volume, surface area, and hydration changes for equilibrium unfolding and formation of aggregation transition state: High-pressure and cosolute studies on recombinant human IFN-γ
The equilibrium dissociation of recombinant human IFN-γ was monitored as a function of pressure and sucrose concentration. The partial molar volume change for dissociation was −209 ± 13 ml/mol of dimer. The specific molar surface area change for dissociation was 12.7 ± 1.6 nm2/molecule of dimer. The first-order aggregation rate of recombinant human IFN-
