1. Expansion of cord blood stem cells in fibronectin-coated microfluidic bioreactor
ABSTRACT Background: Hematopoietic stem/progenitor cell transplantation is the main treatment option for hematological malignancies and disorders. One strategy to solve the problem of low stem cell doses used in transplantation is pre-transplant expansion. We hypothesized that using fibronectin-coated microfluidic channels would expand HSPCs and keep self-r

2. Global and Local Oriented Gabor Texture Histogram for Person Re-identification
ABSTRACT: Automated person re-identification is a key process in global distributed camera systems. This paper proposes a new feature, the Global and Local-Oriented Gabor Texture Histogram (GLOGTH), for person re-identification. GLOGTH is a combination of the local texture and global structure information of a given input image. This feature aims at represen

3. Aplicação do Formalismo CTP em uma Ação com Operador Pseudo-Diferencial
Resumo O formalismo CTP (closed-time-path) é uma ferramenta matemática para calcular funções de Green em sistemas físicos. A principal vantagem desta técnica é a de que, ao contrário do formalismo de Feynman, o formalismo CTP pode ser aplicado em sistemas fora do equilíbrio. Por outro lado, em física da matéria condensada, alguns modelos não loca

4. SIMULATION OF THERMAL DECOMPOSITION IN AN OPEN CAVITY: ENTROPY ANALYSIS
ABSTRACT This paper presents a numerical analysis of entropy generation in a two-dimensional rectangular channel where the inlet flow undergoes thermal decomposition resulting from a chemical reaction. The model considered viscosity and thermal conductivity to be dependent of temperature. Irreversibility due to mass transport was included in the entropy gene

5. The delusional dimension of anorexia nervosa: phenomenological, neurobiological and clinical perspectives
Abstract Background Delusional characteristics have been largely ignored in patients suffering from anorexia nervosa (AN). Objectives To review the literature on delusional features in AN from phenomenological, neurobiological, and clinical viewpoints. Methods Data were obtained through searches of Medline, PubMed, SciELO and Cochrane Library. Results Di

6. Molecular dynamic study of the jet noise about the micro-scale tube
This paper studies the two-dimensional micro-scale molecular simulations of the jet flow using Lagrange discrete systems and adopting Andresen flexible constraint mechanism. At the effects of different excitation conditions and boundary conditions, the low Mach number flow field and sound field are obtained, and characteristic results are given. At the jet f

7. Avaliação de fármacos fotossensíveis derivados da cloro alumínio ftalocianina no tratamento da progressão tumoral em modelo de matriz tridimensional mista / Evaluation of photosensitizers aluminum chloride phthalocyanine derivatives in the treatment of tumor progression in three-dimensional matrix.
Wound healing process can be favored by Low Level Laser Therapy, with the collagen and elastin matrix a dermic substitute described as an appropriate system in tissue engineering and in tridimensional skin systems. With this purpose, a study was elaborated using the system nanoemulsion of aluminium-chloride phthalocyanine (ClAlPc) as photosensitizer in skin

8. Modelos numéricos de vigas mistas de aço e concreto pertencentes a sistemas de pisos mistos de pequena altura em situação de incêndio / Numerical modelling of composite slim floor beams in fire
Slim floor frames consists on structural system in which the steel beam is completely or partially inserted in a concrete slab, that is usually used in profiled steel decks systems. The main goal of the slim floor systems is to obtain a minimum height of the composite beam section and, consequently, achieve a higher height of the floor or a lower total heigh

9. Blendas e filmes de quitosana/amido de milho: estudo da influência da adição de polióis, oxidação do amido e razão amilose/amilopectina nas suas propriedades / Chitosan/corn starch blends and films. Influence of polyol addition, starch oxidation and amylose/amylopectin ratio in their properties
Chitosan/starch association represents an interesting alternative to the preparation of biocompatible drug delivery systems, packing materials and edible films. Changes in rheological, thermal and mechanical properties, water vapor permeability and solubility of chitosan/starch films were evaluated varying the starch structure form (gelatinized or oxidized),

10. Desenvolvimento de métodos cromatográficos hifenados (in-tube SPME/LC-FLD e GCxGC/qMS) para análises de fármacos e agrotóxicos em amostras complexas / Development of hyphenated chromatographic methods (in-tube SPME/LC-FLD and GCxGC/MS) for analysis of drugs and pesticides in complex samples.
Determination of trace levels of drugs in biological fluids and multiresidue (contaminants) in food samples is extremely important because this generates valuable data for therapeutic drug monitoring (individualization of dosage regimen) and quality control (food safety), respectively. Because of the demand for analytical methods with high resolution and low

11. The role of nonequilibrium thermo-mechanical statistics in modern technologies and industrial processes: an overview
The nowadays notable development of all the modern technology, fundamental for the progress and well being of world society, imposes a great deal of stress in the realm of basic Physics, more precisely on Thermo-Statistics. We do face situations in electronics and optoelectronics involving physical-chemical systems far-removed-from equilibrium, where ultrafa

12. Transição quântico-clássica em sistemas com propensão coletiva / Quantum-to-classical transition in systems with collective propensity
In this thesis, we studied the behavior of quantum systems which in the classical limit may exhibit either regular or chaotic behavior. Our study was based on the dynamical characterization of the, chaotic or regular, behavior of these systems in the classical limit through the analysis of the structure of phase-space distributions functions. Particularly, w
