1. Uma abordagem experimental e numérica para determinação de curvas de compressão para concreto simples e reforçados com fibras de aço
RESUMO A curva tensão-deformação do concreto é importante para o dimensionamento de estruturas, pois por meio dela é possível obter sua resistência à compressão, sua deformação de pico, o módulo de elasticidade e a tenacidade do concreto. Entretanto, essa é uma propriedade que não é comumente determinada nos ensaios de controle de qualidade do

2. Numerical Material Model for Composite Laminates in High-Velocity Impact Simulation
Abstract A numerical material model for composite laminate, was developed and integrated into the nonlinear dynamic explicit finite element programs as a material user subroutine. This model coupling nonlinear state of equation (EOS), was a macro-mechanics model, which was used to simulate the major mechanical behaviors of composite laminate under high-veloc

3. Sustentabilidade de barragens e o planejamento de hidreletricas na Bolivia / Sustainability of dams and hydroelectric plants planning in Bolivia
The construction of dams has been one important option that was used by many countries in order to reach the development. With elapsing of the years the dams has evidence that produce many benefits but also impacts, that s why must be a balance in the choice and determination of the new projects in function of the needs and always with the goal of reach the

4. Explorando equações cartesianas e paramétricas em um ambiente informático
This research has as objective verify if in a computer science environment allows to the student to recognize some curves properties through representations and graphical interpretations in dynamic way with the use of parameters for one comprehension better of its equations. We verified that the articulating between the points of view cartesian and parametri

5. Mechanical characterization of fiber reinforced Polymer Concrete
A comparative study between epoxy Polymer Concrete plain, reinforced with carbon and glass fibers and commercial concrete mixes was made. The fibers are 6 mm long and the fiber content was 2% and 1%, respectively, in mass. Compressive tests were performed at room temperature and load vs. displacement curves were plotted up to failure. The carbon and glass fi

6. Efeito do polissacarideo da soja sobre o aparelho digestivo : avaliação da produção de hidrogenio e da permeabilidade intestinal a lactulose
The study was carried out in 13 healthy male or female volunteers, aged 23-38 years old, with no known active gastrointestinal disease. Subjects consumed a meal consisting only of rice and meat on the night prior to the study. On each study day , the subjects received 1 of 3 test meals on 3 different days - The 3 test meal consisted of the following: 20 g of

7. Survival of Salmonella adelaide and fecal coliforms in coarse sands of the swan costal plain, Western Australia.
The survival of Salmonella adelaide and fecal coliforms in two coarse sands influenced by two sources of septic tank effluent was studied. The experiments were conducted in conditions that reflected the soil environment beneath functioning septic tank systems. Significant differences in survival were found with different effluent sources. In one experiment t

8. Flow volume loops in patients with goiters.
Plain radiology is the standard means of assessing upper airway obstruction in patients with goiters. Flow volume loop curves will provide additional information, because they allow a quantitative assessment of airflow dynamics in the respiratory cycle. Fifty-one patients had flow volume loops performed before and after thyroidectomy. There was a significant

9. In Vitro Testing of Antimicrobial Activity of Bone Cement
The purpose of this study was to establish a reliable and cost-effective microplate proliferation assay for in vitro antimicrobial testing of bone cement samples. Cement samples devoid of antimicrobial agents, loaded with 2% gentamicin or with different concentrations of high-porosity silver, were incubated in a 96-well microplate with several staphylococcal
