3. Laminated composite based on polyester geotextile fibers and polyurethane resin for coating wood structures
New environmental laws have restricted the use of hardwood trees in overhead power lines structures, such as, poles and cross-arms, leading companies to seek alternative materials. Reforested wood coated with polymeric resin has been proposed as an environmental friendly solution, with improved electrical properties and protection against external agents, e.

4. Caracterização das construções com madeira em Uberlândia-MG : patologias, projetos e detalhes / Understanding Buildings with Wood in Uberlândia, MG: Pathology, Projects and Details
A madeira é um material natural com alta resistência, e por isto, é uma opção bastante atraente como elemento estrutural para diferentes usos, seja como pilares, arcos, vigas ou treliças. Possui uma forte tradição de uso em coberturas, com a utilização em telhados convencionais ou aqueles mais trabalhados e aparentes com grande apelo arquitetônico

5. Recomendações para o projeto e construção de estruturas com peças roliças de madeira de reflorestamento / Recommendations for design and construction of structures with roundwood from tree farms
The object of this work is to propose the draft for a handbook with recommendations for the design and construction of structures using treated roundwood originating from forest farming in Brazil. Roundwood structures were classified and characterized visually and mechanically. Guidelines were presented for the desing of bridges and barns with structural and

6. Optimation and dimensional of plane trusses of Wood, applying the genetic algorithms method / OtimizaÃÃo e dimensionamento de treliÃas planas de madeira empregando o mÃtodo dos algoritmos genÃticos
The objective of this study is to present information on the optimization of plane truss wooden structure using the method of genetic algorithms. All assessments are made by the computer program called Optimization Structures Plane (OTP). It was also used the computer program GESTRUT for determining forces and displacement. It was evaluated pitched trusses,

9. Flexural strengthening and stiffness increasing of precast beam-to-column connections by NSM CFRP strips / Reforço e incremento da rigidez à flexão de ligações viga-pilar de estruturas de concreto pré-moldado com polímero reforçado com fibra de carbono (PRFC)
This work presents the development of a technique for flexural strengthening and stiffness increasing of precast beam-to-column connections by the embedding of FRP strips into grooves made on the concrete cover. According to this technique, the tension in the connection is transferred by the Near-Surface Mounted (NSM) FRP strips. To allow the transference of

10. Análise de estruturas de madeira, com e sem impregnação de resina poliuretana derivada do óleo de mamona, aplicadas em linhas de distribuição de energia elétrica / Wooden analysis of structures, with and without polyurethane resin impregnation derivative of the oil of mamona, applied in lines of distribution of electric energy
The power supply dealership companies live together with high maintenance costs on electrical systems, in private one of reasons is linked to the cost and durability of wood crossarms, either in its initial installation, either in its exchange that can occur frequently, having the necessity of noble wood use in principles which, beyond the price, suffer envi

11. Variability of physical and mechanical properties in lots of eucalipto lumber for the building construction. / Variabilidade de propriedades físico-mecânicas em lotes de madeira serrada de eucalipto para a construção civil.
The Eucalyptus genus has been reaching good position in the solid wood market due to its high productivity in wood of satisfactory mechanical quality, providing great availability for the building construction. The up date of the Brazilian Norm for projects of wood structures (NBR 7190/97), has introduced important modifications as the proposition of resista

12. A temporal behaviour analysis of the land cover l band backscatter in the Tapajós national forest, state of Pará, by using jers-1 images / Análise do comportamento temporal do retroespalhamento na banda L da cobertura da terra na Floresta do Tapajós, Pará, utilizando imagens JERS - 1
The temporal evolution of the backscatter for several land cover types in the Tapajós National Forest, Brazilian Amazonia is analyzed using JERS-1 images. Five JERS-1 images were acquired in the dry season from 1993 to 1997. Samples of the studied land cover types were identified after the analysis of a Landast5/TM data set of 12 images obtained from 1984 t
