Book Description
El uso de técnicas Lean en empresas del sector industrial es cada vez más elevado debido a la necesidad de sobrevivir en un mercado cada vez más competitivo, gobernado por la demanda cada vez más alta de precisión y calidad de los productos y servicios. Con un margen de error tan reducido, las empresas se ven obligadas a adentrarse en ése campo que tiene como objetivo principal la reducción de despilfarros además de asegurar unos clientes satisfechos. El aumento de la utilización de estas técnicas contrasta con la cantidad de empresas todavía arraigadas al uso del papel como soporte principal tanto para la gestión interna como para documentos externos, lo cual genera una gran cantidad de residuos además del coste asociado a su uso. El presente proyecto se basa en el caso de una empresa industrial del sector de la automoción con los objetivos de reducir los tiempos de cambio entre productos para así ganar tiempo, reducir los despilfarros, aumentar la producción y al mismo tiempo mejorar los resultados. Este trabajo se hará de la mano de la informatización del sistema de control de producción para acortar el camino desde la introducción a mano de los operarios hasta la posterior introducción de estos datos a un ordenador para ser analizados. La mejora de los tiempos de cambio entre artículos se realizará con el uso de una potente herramienta de Lean Manufacturing como es la metodología SMED y la automatización del sistema de control de producción se desarrollará con el programa de gestión de bases de datos llamada Access de Microsoft Office.

Book Description
The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Book Description
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.

Book Description
This book presents new application processes in the context of anaerobic digestion (AD), such as phosphorus recovery, microbial fuel cells (MFCs), and seaweed digestion. In addition, it introduces a new technique for the modeling and optimization of AD processes. Chapters 1 and 2 review AD as a technique for converting a range of organic wastes into biogas, while Chapter 3 discusses the recovery of phosphorus from anaerobically digested liquor. Chapters 4 and 5 focus on new techniques for modeling and optimizing AD. Chapters 6 and 7 then describe the state of the art in AD effluent treatment. The book’s final three chapters focus on more recent developments, including microbial fuel cells (MFCs) (Chapter 8), seaweed production (Chapter 9), and enzyme technologies (Chapter 10).

Book Description
This book explains in a clear and simple way what life is and how it flows within our cells, between people and through people. It is a practical manual that will help us to "feel" life, to vibrate and breathe the life inside of our bodies and of all living beings. A key focus of this work is how emotional impact affects our pericardium, which is the membrane that envelops, maintains and protects the heart.

Book Description
Teaching Dialogue Interpreting is one of the very few book-length contributions that cross the research-to-training boundary in dialogue interpreting. The volume is innovative in at least three ways. First, it brings together experts working in areas as diverse as business interpreting, court interpreting, medical interpreting, and interpreting for the media, who represent a wide range of theoretical and methodological approaches. Second, it addresses instructors and course designers in higher education, but may also be used for refresher courses and/or retraining of in-service interpreters and bilingual staff. Third, and most important, it provides a set of resources, which, while research driven, are also readily usable in the classroom – either together or separately – depending on specific training needs and/or research interests. The collection thus makes a significant contribution in curriculum design for interpreter education.
