1. Soil Water Retention Curve as Affected by Sample Height
ABSTRACT: The soil water retention curve is one of the main instruments to assess the soil physical quality and to improve soil management. Traditionally, the equipment most used in the laboratory to determine the retention curve has been Haines funnels and Richards chambers. An important factor to which little attention has been given in the use of these eq

2. Hydro-physical characterization of soils under tropical semi-deciduous forest
The study of the hydro-physical behavior in soils using toposequences is of great importance for better understanding the soil, water and vegetation relationships. This study aims to assess the hydro-physical and morphological characterization of soil from a toposequence in Galia, state of São Paulo, Brazil). The plot covers an area of 10.24 ha (320 × 320

3. Study of tension in the periodontal ligament using the finite elements method
Orthodontic movement is process of transformation of a physical stimulation into a force applied to a tooth, with a biological response identified as bone remodelling. Although it is possible to measure the force applied on a tooth, its distribution around the root is irregular forming areas of higher concentration of tensions, which do not correspond to the

4. Análise fotoelástica da distribuição das tensões ocorridas no tecido ósseo, ao redor de cinco diferentes desenhos de implante, quando submetidos ao carregamento axial / Photoelastic analysis of stress distributions occurring around the bone tissue of five different designs of implants when subjected to axial loading
The design of the implant is a highly relevant factor in the distribution of stresses generated in the peri-implant tissues. The proposition of this study was to evaluate the stress distribution of five different designs of implants, when subjected to axial loads uniformly distributed. Were prepared five photoelastic jaws, in which the implants used in this

5. Direitos sociais no Brasil: Programa Bolsa Família e transferência de renda
Our 1988 Federal Constitution, its objectives and fundamental rights, a social reality that is marred by inequality and poverty and social public policies as instruments for the maximum constitutional realization form the pillars of this paper. In the course followed by this Political Letter in search of a free, fair and solidary society, in the context of a

6. The influence of die geometry on stress distribution by experimental and FEM simulation on electrolytic copper wiredrawing
The study of die geometry is vital in determining the surface and mechanical properties of drawn wires, and consequently, their application. In this work, annealed electrolytic copper wire (ETP), with 0.5 mm original diameter was reduced by 19% in dies with 2β = 10º and 18º and Hc = 35 and 50%. The best experimental results were then studied by the Finite

7. Análise de tensões pelo método de elementos finitos em próteses dento-implanto-suportadas: Influência da extensão da prótese e diâmetro do implante
The impossibility of using implants as independent supports of the prosthesis in the patients treatment partially edentulous, mainly in cases of anatomical limitations, makes possible for the implants to be added to the natural teeth, characterizing the tooth-implant-supported prosthesis. The conditions for it to be a viable prosthetic option, justifies know

9. Entre drogas e cachaÃa: a polÃtica colonial e as tensÃes na AmÃrica Portuguesa (Capitania do Rio de Janeiro e estado do MaranhÃo e GrÃo-ParÃ, 1640-1710)
The XVII century was marked for the Portuguese empire overseas as a turbulent period, not only on account of collisions made to resume the crown of the hands of Hispanics, as well as to make its sovereignty and power remained intact in American achievements. Threatening this objective, many social movements erupted in the tropics, however, the target of rebe

10. Analise fotoelastica da distribuição de tensões em dois sistemas de proteses mandibulares sobre implantes : barra distal e solda a laser / Photoelastic analysis of the distribution of the tensions in two systems of mandibular prosthesis over implants : distal bar and laser welding
Este estudo avaliou por meio de análise fotoelástica, a distribuição in vitro das tensões geradas na interface "osso/implante" em próteses mandibulares, tipo protocolo, comparando duas técnicas de confecção: Solda a laser e Barra Distal (Neodent, Curitiba - PR) onde não se utiliza infra-estrutura metálica. Foram confeccionadas duas próteses com d
