25. Estimativa da eficiência do ensaio SPT através da execução da prova de carga estática sobre o amostrador / Estimation of the efficiency in SPT test through static load tests to the sampler
The Standard Penetration Test, SPT, is one of the most used one for subsoil information in the USA and Brazil. The data obtained in this dynamic test, such as the penetration resistance index, NSPT, the soil classification and phreatic level are used by different methods to estimate the shallow and deep foundations load capacity. For the same soil, the index

26. Propriedades de madeiras termorretificadas / Properties of thermalrectified wood
Heat treatment applied to the wood leads to the degradation and/or rearrangement of its principal chemical constituents, especially cellulose, hemicelluloses, and lignin, improving some properties such as dimensional stability, resistance to attack by wood decay organisms, and reducing the hygroscopicity. This occurs mainly by the OH groups degradation prese

27. Investigação de parâmetros do CCR com incorporação de escória granulada de alto forno para utilização como base de pavimentos. / Analysis of mechanical behavior of the RCC with incorporation of granulated blast furnace slag for use as pavement base.
The increasing environmental concerns as well as energy sources shortage leads industry to consider both optimization of production processes and sustainable use and disposal of its by-pass products. In siderurgical steel manufactures the most common by-pass product is the blast furnace slag with emphasis to its granulated shape. This study considered the ev

28. Postural control in elderly submitted to multi-sensory versus strength exercises: a randomized single-blind study / Controle postural em idosos submetidos a treinamento resistido versus exercícios multissensoriais: um estudo aleatorizado e simples-cego
The practice of regular exercise in aging is helpful to bring benefits in all aspects older peoples life, especially on senescence individuals postural control that tend to reduce such capacity. The aim of this study was to verify and to analyze the changes promoted by two types of exercise programs on postural control in healthy elderly. The study design wa

29. Educação infantil, espaços de confronto e convívio com as diferenças: análise das interações entre professoras e meninas e meninos que transgridem as fronteiras de gênero / Early childhood education, spaces of confrontation and familiarization with differences: analysis of interactions between teachers and girls and boys who transgress the gender boundaries
This thesis presents the study of gender in a municipal school of Early Childhood Education (Emei). Conducted in the city of São Paulo, the objective of the study was to analyse the interactions between teachers and children and, in special, observe and interpret the children that, to crossing the line of the patterns imposed on them, transgress the gender

30. ESTUDO DA LIQUEFAÇÃO ESTÁTICA EM REJEITOS E APLICAÇÃO DE METODOLOGIA DE ANÁLISE DE ESTABILIDADE
Liquefaction is a phenomenon that happens in saturated granular soils when undergoing loadings rapid enough to produce great pore pressure increase with the consequent reduction of the effective stress and the shear strength. In the mining context, the possibility of the liquefaction occurrence in the granular tailings, when saturated, is a relevant concern

31. PROPRIEDADES FÍSICO-MECÂNICAS E RESISTÊNCIA A BIODETERIORADORES DE CHAPAS AGLOMERADAS CONSTITUÍDAS POR DIFERENTES PROPORÇÕES DE MADEIRA E CASCA DE ARROZ / PHYSICAL-MECHANICAL PROPERTIES AND DECAY RESISTANCE OF WOOD AND RICE HUSK PARTICLEBOARD IN DIFFERENT PROPORTIONS
This work aimed at evaluating the quality of particleboards manufactured with different wood proportions (Eucalyptus grandis W. Hill. ex Maiden) and rice husk. The composites were produced in the proportions 0, 20, 40, 60, 80 and 100% of peels of rice with the use of urea-formaldehyde and tannin-formaldehyde adhesives. In order to characterize the quality of

32. ESTUDO TEÓRICO EXPERIMENTAL DAS PROPRIEDADES DINÂMICAS DO BAMBU / THEORETICAL AND EXPERIMENTAL ANALYSIS OF DYNAMIC PROPERTIES OF BAMBOO
The studies carried on during the last three decades with respect to bamboo have been directed to the physical, mechanic and microstructural characterization of different species, under static load. The experience has shown that the houses and buildings constructed using bamboo as structural element have had good resistance to earthquakes. This work is one o

33. DESEMPENHO DE DUAS ESPÉCIES FLORESTAIS EM COMBINAÇÃO COM CASCA DE ARROZ NA FABRICAÇÃO DE PAINÉIS CIMENTOMADEIRA / PERFORMANCE OF TWO SPECIES IN COMBINATION WITH RICE HUSK IN THE MANUFACTURE OF CEMENT-WOOD PANELS
The present paper had as objective the evaluation of performance of panels composed by cement and different proportions of two combined wooden species with rice husk. There, were applied treatments where the levels of wooden residues were 0, 25, 50, 75 and 100%, while the proportion of rice husk was 100, 75, 50, 25 and 0%, respectively. The wood species in t

34. ANÁLISE LABORATORIAL DE MISTURAS ASFÁLTICAS ABERTAS USINADAS A QUENTE COM A UTILIZAÇÃO DE DIFERENTES LIGANTES
This research Project was conceived with the objective of comparing the performance of three open graded asphalt mixes, all three with the same aggregate gradation for all dosages, on which three different asphaltic binders were used; one conventional binder, one with the addition of co-polymers SBS and another one modified by the addition of ground rubber f

35. Fluidodinâmica de leitos fluidizados e vibrofluidizados operando com partículas planas
The use of fluidized beds as a unit operation for drying of particulate materials is common in industrial processes. However, most works published in the literature, focus the drying of uniform particles, in a narrow range of size distribution. The appealing characteristics of fluidization for drying led some authors to suggest its use for drying of particle

36. Retroanálise probabilista aplicada à análise dinâmica da cravação de estacas. / Probabilistic back-analysis applied to dynamic loading test for pile driving.
An dynamic loading test can be performed in concrete piles, bored piles, drilled shafts, auger cast-in-place (continuous flight auger) piles. Such essay bases on the Theory of the Propagation of Wave in piles with the aim of evaluate the capacity of static load mobilized from the dynamic event. The analysis of the test is made by a PC program (p.e. CAPWAP or
