1. About the use of semi-continuity in simply supported composite steel and concrete beams, to remove fireproof coatings for standard-fire resistance requirement of less than 30 minutes
Resumo Estudos anteriores do comportamento sob ação do incêndio de vigas mistas de aço e concreto, sem instabilidades locais (ditas compactas), considerando a rigidez à flexão nos apoios fornecida pela armadura negativa longitudinal à viga (semicontinuidade), mostraram que não é possível justificar a ausência de revestimento contra fogo para tempo

2. Obtención y caracterización de recubrimientos de biovidrio sobre la aleación de Mg AZ31
ABSTRACT The ideal material for a metal bone prosthesis must undergo a gradual corrosion in vivo, without releasing toxic components, while acting as a support and facilitating the growth of bone tissue, until a replacement is completed by the regenerated bone. . Biodegradable magnesium alloys have been studied because of their excellent mechanical propertie

3. Pollen morphology of Waltheria L. (Malvaceae-Byttnerioideae) from Bahia, Brazil
ABSTRACT Waltheria encompasses about 60 species distributed in Brazil and Mexico. To improve the palynology of the genus, we analyzed 14 species occurring in the Brazilian State of Bahia. Pollen grains were acetolyzed and examined using light microscopy and scanning electron microscopy. Non-acetolyzed pollen grains were viewed by transmission electron micros

4. TREATMENT OF SEPTIC TANK SLUDGE IN A VERTICAL FLOW CONSTRUCTED WETLAND SYSTEM
ABSTRACT: The study consisted of the evaluation of the treatment of septic tank sludge in a vertical constructed wetland system (CW), built according to the first stage of the French system. The system operated also for sewage treatment and one of the beds (area of 29.1 m2, height of the support medium of 0.7 m and planted with Tifton 85 grass, Cynodon dacty

5. Oxygen air enrichment through composite membrane: application to an aerated biofilm reactor
A highly permeable composite hollow-fibre membrane developed for air separation was used in a membrane aerated biofilm reactor (MABR). The composite membrane consisted of a porous support layer covered with a thin dense film, which was responsible for oxygen enrichment of the permeate stream. Besides oxygen enrichment capability, dense membranes overcome maj

6. PARALLEL TOPOLOGICAL SUPPORT FOR FINITE ELEMENT MESHES IN DYNAMIC FRACTURE AND FRAGMENTATION ANALYSES / SUPORTE TOPOLÓGICO EM PARALELO PARA MALHAS DE ELEMENTOS FINITOS EM ANÁLISES DINÂMICAS DE FRATURA E FRAGMENTAÇÃO
Fracture propagation and fragmentation phenomena in solids can be described by Cohesive Zone Models and simulated with the Finite Element Method. Among the computational approaches of recent interest for fracture representation in finite element meshes are those based on cohesive elements. In those approaches, fracture behavior is represented by cohesive ele

7. Ciclo de vida, estrutura foliar e variações morfoanatômicas influenciadas por diferenças ambientais para Victoria amazonica (POEPP.) J.C. Sowerby (Nymphaeaceae) na Amazônia Central
The Amazon floodplains are specific ecosystems with high biodiversity and endemism, divided in varzeas, white fertile waters, and Igapos with poor and acid waters, black or clear, and mixed waters between the two typologies. This study aimed to characterize morphologically and anatomically leaf structure, germination and life cycle of Victoria amazonica (Poe

8. Interação do alendronato e da vitamina K no metabolismo osteomineral de ratas ovariectomizadas
The bone is a specialized form of connective tissue that provides support for metabolic and biomechanical throughout the body. Thus, the bone is very dynamic, with constantly renewing itself. His integrity therefore depends on the balance between the processes of formation and resorption. The loss of this balance alters both the structure of organic matrix a

9. Evolução urbana e dinâmica da paisagem em setores periféricos da metrópole paulistana: o caso de Taboão da Serra - SP / Evolution and dynamics of urban landscape in peripheral sectors of Sao Paulo: the case of Taboao da Serra - SP
The research aims to examine the influences of urbanization concentrated (compact) , and how this feature changes the environmental conditions and the balance of local landforms by modi fying the geographic stratum of the landscape. For this analysis, we had to support the mapping of the evolution of urban land use in Taboão da Serra at two different times

10. Limitações à reprodução assistida - a mercantilização da espécie humana: regras do biodireito e da bioética - a necessidade de legislação específica
The law currently is facing a need in the world, both countries small, medium or large development, which is the implementation of legal system to evaluate cases with disputes arising in the Assisted Human Reproduction. The lack of specific legislation, makes any fragile situation of the people, whether in the actual practice of assisted human reproduction,

11. GrÃficos compactos com curvatura mÃdia de segunda ordem constante sobre a esfera / Compact graphs over a sphere of constant second order mean curvature
The purpose of this dissertation is to desire a formula for the operator Lr(g) = div(Pr gradient g) of a new support function g, defined over a hypersurface Mn in a Riemannian space form Mc n +1, and to show that a compact smooth starshaped hypersurface Σn in the Euclidean sphere Sn+1,whose second symmetric function S2 is positive and constant must be a

12. Some results about ergodic optimization for noncompact spaces / Alguns resultados sobre otimização ergódica em espaços não compactos
Let X be a topological space not necessarily compact, and T:X->X a continuous map. If f:X->R is a continuous function, we seek conditions on f in order to guarantee existence of maximizing measures that are characterized in terms of its support.
