25. Oportunidades de aprendizagem organizacional na gestão de projetos: pesquisa-ação em uma empresa de engenharia consultiva
In recent years the possibility of incorporating the process of Learning Organizational (LO) during the life cycle of projects has been drawing the attention of scholars. However, there are few studies that analyze the subject in a practical and deeper way. The traditional studies try to consider and discuss the learning after the project more accurately due

26. Imobilização da tanase de Paecilomyces variotii e ação em reações de hidrólise e síntese / Immobilization of tannase from Pecilomyces variotii and reactions of hydrolysis and synthesis
Tannin acyl hydrolase (TAH) known as tannase (EC 3.1.1.20) is an enzyme that hydrolyzes esters of hydrolysable tannins producing gallic acid and glucose as the reaction medium is polar. However, the literature indicates their ability to produce also gallic acid esters in organic media. Our research group has isolated a fungus, Paecilomyces variotii, tannase

27. Vazios urbanos e imóveis subutilizados no Centro Histórico tombado da cidade de João Pessoa
This dissertation aims to identify, quantify and characterize the urban voids and underutilized properties present in the area of the Historic Center of João Pessoa - listened by IPHAN. The object of research was delimited from the questioning of the existence of a housing stock capable of reuse in polygonal of rigorous preservation of IPHAN to the Center o

28. Blocos para execução de alvenaria de vedação empregando garrafas pet: avaliação mecânica e termoacústica
Recycling and reuse of materials is the most evident solution regarding sustainable development. One relevant aspect to this development refers to the integration of engineering to devise ways that enable the reuse of materials considered as waste, but with great potential of applicability in the building industry itself, through the generation of appropriat

29. Projeto industrial para aeração automática de leiras de compostagem orgânica / Industrial project for automated aeretion of organic composting piles
Composting is a safety environmental alternative to reuse and treat organic wastes produced by human-beings. Although decomposition naturally happens, the handling of some factors, such as oxygen level, temperature, moisture content and pH, can alter the process speed, accelerating microbial activity. Aeration is a crucial practice during the composting proc

30. Integração do processo de cristalização de frutose por adição de antissolvente
Fructose (C6H12O6) is a monosaccharide with increasing industrial interest, and with some advantages over other sugars, facts that have motivated many studies about its production from its aqueous solution, by crystallization. Fructose crystallization occurs, in general, with the addition of ethanol as anti-solvent, aiming the reduction of its solubility and

31. Theorizing ICT and society in the Brazilian context: a multilevel, pluralistic and remixable framework
In this paper we present a multilevel and pluralistic conceptual framework that is particularly useful for Brazilian researchers investigating information and communication technology (ICT) based social changes from a community/societal level of analysis. The framework is influenced by three theoretical perspectives: social shaping of technology, structurati

32. Chemistry and tensile properties of a recycled AA7050 via spray forming and ECAP/E
The aim of this work is to evaluate the conjugation of advanced processing techniques, such as spray forming, extrusion and ECAP as a processing route for reuse of machining chips generated during aircrafts manufacturing parts from AA7050-T7451 raw material plates supplied according to AMS 4050H¹. In this way, the sprayforming process was used for remelting

33. A web service application to support distributed manufacturing
Manufacturing as an industrial activity that starts with the conceptual project and ends with proper material disposal or its reuse has evolved from a centralized to a distributed process. The several components of the process are distributed according to space and time. This evolution was possible due to the support of information technology, which allows m

34. Tratamento da água de purificação do biodiesel utilizando eletrofloculação
Biodiesel was created as a solution for a great economic and enviromental problem of petroleum, a resource with sustainable characteristics. But its production still needs optimization, because it uses a lot of water and generates a large volume of this residue, which appears improper to disposal without correct treatment. This work propose an economic, viab

35. Elaboración de recubrimientos cerámicos mediante proyección térmica por combustión a partir de residuos sólidos industriales
Ceramic coatings were elaborated onto carbon steel substrates by oxy-fuel thermal spraying process from catalysts waste used in petroleum refining. The adhesion and micro-hardness Vickers were evaluated according to ASTM C633-01(2008) and ASTM C1327-08 standards respectively, with adhesion values varying between 2,9 and 17,7 MPa and values of microhardness V

36. Aproveitamento de membranas de osmose inversa descartadas da indústria para o reuso da purga de torres de resfriamento
Reverse osmosis plants use new membranes to produce demineralized water. After a period of three to five years, the membranes are replaced by news ones due to levels of treatment which are not suitable for production of water with the desired characteristics. This process generates a lot of rejected modules causing an environmental problem. The present work
