15. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t

17. Linguagens de domínio específico e sensores baseados em modelos biológicos de computação
A Domain Specific Language is a specification language dedicated to a particular domain, representation technique, or solution searching method. On the other hand, a general-purpose programming language is a language designed with the goal of emulating Lambda Calculus or Turing Machine. Since general-purpose languages must accept any algorithm that can be ex

19. O mecanismo de desenvolvimento limpo (MDL) e transferência de tecnologia: o projeto de MDL do aterro sanitário de Salvador / O mecanismo de desenvolvimento limpo (MDL) e transferência de tecnologia: o projeto de MDL do aterro sanitário de Salvador
This study aims to verify technology transfer occurrence in the Clean Development Mechanism (CDM). This study object serves as an economic motivation for nations that need to reduce their carbon dioxide emission rates during the 2008-2012 marking period. The CDM takes all practicable steps to promote, facilitate and finance, the transfer of, or access to, en

20. Resposta de forrageiras à diferentes doses de lodo de curtume de tecnologia limpa em condições controladas e a campo / Response of forage to different doses of sludge from tannery of "clean technology" under controlled conditions and field
Industrial processes generate waste such as sludge from tannery "clean technology" that can be used in agriculture, to increase the productivity and supply of nutrients to the soilplant system. On this basis it was aimed to assess the feasibility of using primary sludge from a tannery in clean technology in the fertilization of pasture grasses and forage leg

23. Study of laser textured and coated cutting tools used in face milling of compacted graphite cast iron / Estudo da caracterização de ferramentas de corte texturizadas a laser e revestidas utilizadas no fresamento frontal de ferro fundido vermicular
The controlled alteration of a surface can improve the performance of a mechanical part. The texture is the digital impression of a surface composed of hills and cavities, normally disordered distributed. When this texture is uniform and regularly distributed on a surface, it can modify significantly the functionality of a component. A technique used to unif
