Purpose -The purpose of this paper is to contribute to defining the tasks necessary to process management, considering both conceptual and practical views. Design/methodology/approach -Bibliographic review for tasks mentioned as typically necessary to process management, plus a field survey involving professionals working in process management. Findings -The bibliographic review yielded a set of tasks that were grouped conceptually into "designing processes", "managing processes from day to day" and "fostering process-related learning". These groups were then validated with practioners as valid constructs. The field survey produced two major findings: the first underlining the practical importance of the tasks identified as necessary to process management and the second demonstrating that most organizations where the study participants work are structured functionally, but have practices for managing cross-functional processes or "end-to-end process". The conceptual and practical comparison brings to light gaps between authors and professionals. Research limitations/implications -There is significant variation in the job positions and sectors occupied by the group studied and the sample is not random, given that all are enrolled in postgraduate process management programs and thus share an interest in the subject. Practical implications -Organizations can identify tasks that are necessary and important to process management and have an instrument (the questionnaire) for deciding how best to manage processes. Where functional management of cross-functional processes is found, this recommends developing organizational solutions to upgrade the capacity for coordination among activities without necessarily introducing changes in organizational structure. Originality/value -The paper describes an unprecedented study and helps clarify what needs to be done to manage processes.

Population growth, especially in urban areas, combined with modern levels of social consumption, contribute for a significant increase of waste production. Among the environmental impacts resulting from the operation of landfills, the generation of leachate is certainly one of the most significant and most difficult to control. The composition of leachate is complex and varied; it contains physicochemical and biological characteristics that are aggressive to the soil, water resources, fauna and flora. The technical and operational difficulties to handle it are challenges for waste managers. There are several methods to treat leachate which are widely debated in the literature, each having advantages and disadvantages. The present paper has the objective of carrying out a bibliographical review of leachate treatment from landfills, addressing the main technologies, as well as discussing their applications, advantages, disadvantages and uncertainties. According to what was studied, the technologies that have been found to have the best practical results and, in general, reach the parameters for treated effluent provided for environmental legislations, are those that use filtering membranes. However, one of the major disadvantages of these processes is the generation of a concentrate, which is normally recirculated in the landfill itself.

The oxidation of propane on was studied with Pt-xWO3/Al2O3 catalysts was studied ,by varying the concentration of tungsten sublayer. Thermal analysis and XRD in situ showed that the enrichment of tungsten at the surface is associated with the formation of HxWO3 bronze. FTIR results with C3H8 and O2 indicated that the catalyst surface properties and the interaction between W and Pt were modified. These modified surface complexes prevented the formation of acetates and formate species. The addition of W increased the activity of Pt/Al2O3 towards in C3H8 oxidation. Tungsten was the main responsible for the stability of the bimetallic catalysts in the presence of water

É corriqueiro para a indústria de Óleo e Gás operar em ambientes extremamente críticos e complexos, os quais exigem total conformidade em todos os materiais utilizados em suas atividades produtivas. Diante disto, este artigo tem como principal objetivo apresentar um estudo de caso realizado em uma empresa fornecedora de sapatas para tal indústria, as quais são utilizadas na cimentação de poços durante a etapa de revestimento. O estudo evidencia a melhoria obtida neste processo, baseando-se na utilização de técnicas de modelagem para mapeamento do processo de fabricação e aplicação da ferramenta DMAIC como forma de análise, correção e controle a fim de eliminar não conformidades, defeitos e reduzir desperdícios, otimizando as atividades desenvolvidas, consequentemente obtendo maior eficiência.
