1. Kinetics and Thermodynamics of Thermal Inactivation of β-Galactosidase from Aspergillus oryzae
ABSTRACT For optimization of biochemical processes in food and pharmaceutical industries, the evaluation of enzyme inactivation kinetic models is necessary to allow their adequate use. Kinetic studies of thermal inactivation of β-galactosidase from Aspergillus oryzae were conducted in order to critically evaluate mathematical equations presented in the lite

2. Functionalized Multi Walled Carbon Nanotubes as a Carrier for Doxorubicin: Drug Adsorption Study and Statistical Optimization of Drug Loading by Factorial Design Methodology
Multi walled carbon nanotubes (MWNTs) have been identified as an efficient drug carrier. Here a controlled drug delivery system based on modified MWNTs with polyethylene glycol (PEG) was developed (MWNTs-PEG). Then doxorubicin (DOX) as an anticancer drug loaded to nanocarrier. All the parameters affecting the DOX adsorption such as: dose of adsorbent, pH, in

3. A segunda lei da termodinâmica
Considering intrinsic characteristics of the system exclusively, both statistical and information theory interpretations of the second law are used to provide more comprehensive meanings for the concepts of entropy, temperature, and Helmholtz and Gibbs energies. The coherence of Clausius inequality to these concepts is emphasized. The aim of this work is to

4. Modelos estatísticos para o ordenamento nemático biaxial / Statistical models for the biaxial nematic ordering
Consideramos o modelo de Maier-Saupe com a discretização de Zwanzig para as possíveis orientações das moléculas de cristais líquidos nemáticos. Esse modelo reproduz a transição de fases nemático-isotrópica dos cristais líquidos termotrópicos em acordo com a teoria fenomenológica de Maier e Saupe. Introduzimos variáveis desordenadas de forma a

5. Termodinâmica estatística de não-equilíbrio da condensação de Fröhlich-Bose-Einstein de mágnons excitados / Non-equilibrium statistical thermodynamics of the Fröhlich-Bose-Einstein condensation of hot magnons
Este trabalho tem por objetivo desenvolver uma teoria sobre a termodinâmica de não-equilíbrio de mágnons excitados por fonte externa e em contato com um banho térmico. A teoria é aplicada ao recém observado acúmulo de mágnons nos estados de mínima freqüência em experimentos com filmes finos magnetizados de granada de ferro-ítrio afastados do equ

6. Implementação e testes de Métodos Monte Carlo para simulação de equilíbrio sólido-líquido / Development and tests of Monte Carlo methods for solid-liquid equilibrium simulation
O estudo a nível microscópico do Equilíbrio Sólido-Líquido (ESL) só se desenvolveu a partir do século XX e ainda existem aspectos de tal fenômeno que não são bem compreendidos, mesmo para os sistemas mais simples. Por esse motivo, é necessário que métodos eficientes para simular diretamente o ESL sejam formulados. O principal objetivo deste trab

7. Aproximación didáctica a la termodinámica con modelos y literatura de ciencia ficción
Energy transformations teaching at secondary school, generally relate to conservation and transference. Moreover, the subject related to the dispersal of energy receives no special attention. There is a general consensus that entropy is one of the more difficult concepts. So we made an investigation with students from the last year of the secondary school wh

8. Dark Energy and The Accelerating Universe: Conceptual Aspects and Observational Tests / Energia escura e aceleração do Universo: Aspectos conceituais e testes observacionais
In the last decade, the extraordinary progress of the astronomical observations (distances with supernovas, matter and cosmic background radiation (CBR) power spectrum, X-ray surface brightness of galaxy clusters, etc) associated with important theoretical developments turned Cosmology one of the most exciting frontiers of contemporary science. In this thesi

9. Nonextensive relativistic nuclear and subnuclear equation of state
Following the basic prescriptions of the Tsallis' nonextensive relativistic thermodynamics, we investigate the relevance of nonextensive statistical effects on the relativistic nuclear and subnuclear equation of state. In this framework, we study the first order phase transition from hadronic to quark-gluon plasma phase by requiring the Gibbs conditions on t

10. Nonadditive entropy and nonextensive statistical mechanics -an overview after 20 years
Statistical mechanics constitutes one of the pillars of contemporary physics. Recognized as such - together with mechanics (classical, quantum, relativistic), electromagnetism and thermodynamics -, it is one of the mandatory theories studied at virtually all the intermediate-and advanced-level courses of physics around the world. As it normally happens with

11. Topologia, Simetria e transições de fase em Modelos de Spin
We use a topological approach to describe the frustration- and field-induced phase transitions exhibited by the infinite-range XY model on the AB2 chain, including noncollinear spin structures. For this purpose, we have computed the Morse number and the Euler characteristic, as well as other topological invariants, which are found to behave similarly as func
