Este livro apresenta a criação de diretrizes para a implantação das Práticas de Gestão do Conhecimento (PGCs) no contexto da Educação a Distância (EAD), com foco no processo de produção de Ambientes Virtuais de Aprendizagem (AVAs). Para a construção das diretrizes foram identificados, primeiramente, os Fatores Críticos de Sucesso e formulados, com base nesses fatores, o Modelo de EaD suportado por PGCs. Como resultado, foram identificadas (05) proposições, contendo (37) diretrizes para implantação da GC, cujo intuito está na melhoria da qualidade e sucesso nos serviços e projetos de EaD.
This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
The production of wastewater from various human and industrial activities has a harsh impact on the environment. Without adequate treatment, the disposal of this wastewater poses a threat to the quality of water globally. Technologies for the Treatment and Recovery of Nutrients from Industrial Wastewater investigates emergent research and best practices within the field of wastewater management. Highlighting novel technological tools in wastewater treatment, effective nutrient removal technologies, and innovative solutions to quality water preservation practices, this book is a critical reference source for professionals, scientists, academics, and students.
