1. O Efeito da Assimetria de Informação Entre o Regulador e os Bancos no Requerimento de Capital Para Risco Operacional
Resumo Em meio às discussões sobre o novo modelo padronizado (SMA) para requerimento de capital para risco operacional e a possível extinção dos modelos internos (AMA), este estudo analisa os efeitos da assimetria de informação (forte característica do risco operacional) nas interações entre o regulador e o banco quanto à adoção de modelos inter

2. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

3. Psychometric properties of the WHOQOL-SRPB BREF, Brazilian Portuguese version
Objective: To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organization’s Quality of Life Instrument – Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF). Methods: In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-fo

4. Comparing an Ensemble Kalman Filter to a 4DVAR Data Assimilation System in Chaotic Dynamics
ABSTRACT: In this paper, the Ensemble Kalman Filter is compared with a 4DVAR Data Assimilation System in chaotic dynamics. The Lorenz model is chosen for its simplicity in structure and the dynamic similarities with primitive equations models, such as modern numerical weather forecasting. It was examined if the Ensemble Kalman Filter and 4DVAR are effective

5. On Micro-Buckling of Unidirectional Fiber-Reinforced Composites by Means of Computational Micromechanics
Abstract Micro-buckling of unidirectional fiber-reinforced composites is investigated in this paper by means of an explicit representation of a geometrically imperfect fiber within the context of kinematical and material non-linear behavior. Two types of fiber imperfections are considered: a helicoidal shape, identified as 3D imperfection; and a sinusoidal p

6. Prolonged viability of human organotypic skin explant in culture method (hOSEC)
Abstract BACKGROUND: Currently, the cosmetic industry is overwhelmed in keeping up with the safety assessment of the increasing number of new products entering the market. To meet such demand, research centers have explored alternative methods to animal testing and also the large number of volunteers necessary for preclinical and clinical tests. OBJECTIVES:

7. Sliding frame-solid interaction using BEM/FEM coupling
In this work it is presented a coupling between the Boundary Element Method (BEM) and the Finite Element Method (FEM) for two-dimensional elastostatic analysis of frame-solid interaction. The BEM is used to model the matrix while the reinforcement is modeled by the FEM. Regarding the coupling formulation a third degree polynomial is adopted to describe the d

8. Failure criterion for adhesively bonded joints using Arcan´s experimental method
Characterization of polymeric materials mechanical behavior requires some previous knowledge about their structure, which allows the choice of more appropriated models and methods. Polymeric materials, below their glass transition temperature (Tg), may be handled as perfect elastic solids, allowing the use of classic mechanics to characterize their behavior.

9. Bench surgical training with lyophilized esophageal segments
PURPOSE: To present lyophilized esophageal segments that can be used to learn surgical skills. METHODS: Four esophagus were harvested from four non-esophagus related research dogs at the moment of euthanasia. Each esophagus was trimmed in 3 cm long segments. They were lyophilized and stored during 30 days. The day programmed for surgical skills practice, the

10. Sobre a transitoriedade das relações afetivas entre homens e mulheres na sociedade pós-moderna / Sobre a transitoriedade das relações afetivas entre homens e mulheres na sociedade pós-moderna
So many broken relationships, a continuous search for the perfect relationship, a lack of commitment between men and women of unrestrained trade partners, the dissolution of a relationship in the face of any adversity. Observe personal relationships leads us to examine more deeply the society in which they are formed, under what criteria, guidelines or even

11. Three essays on local demand for public services
Local provision of public services has the positive effect of increasing the efficiency because each locality has its idiosyncrasies that determine a particular demand for public services. This dissertation addresses different aspects of the local demand for public goods and services and their relationship with political incentives. The text is divided in

12. Efeito de materiais particulados em sistemas modelos de biomembranas / Effect of Particulate Material on Biomembrane Model Systems
This work presents some of the properties of mimetic systems of pulmonary surfactants (PS) composed of dipalmitoylphosphatidylcholine (DPPC) and DPPC/cholesterol and their interactions with particulate material (PM) originated from the burning of sugar cane leaves which is known by clinical studies as an injurious agent of the respiratory airways. The PM des
