Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

STRUCTURAL ANALYSIS WITH THE FINITE ELEMENT METHOD Linear Statics Volume 1 : The Basis and Solids Eugenio Oñate The two volumes of this book cover most of the theoretical and computational aspects of the linear static analysis of structures with the Finite Element Method (FEM). The content of the book is based on the lecture notes of a basic course on Structural Analysis with the FEM taught by the author at the Technical University of Catalonia (UPC) in Barcelona, Spain for the last 30 years. Volume1 presents the basis of the FEM for structural analysis and a detailed description of the finite element formulation for axially loaded bars, plane elasticity problems, axisymmetric solids and general three dimensional solids. Each chapter describes the background theory for each structural model considered, details of the finite element formulation and guidelines for the application to structural engineering problems. The book includes a chapter on miscellaneous topics such as treatment of inclined supports, elastic foundations, stress smoothing, error estimation and adaptive mesh refinement techniques, among others. The text concludes with a chapter on the mesh generation and visualization of FEM results. The book will be useful for students approaching the finite element analysis of structures for the first time, as well as for practising engineers interested in the details of the formulation and performance of the different finite elements for practical structural analysis.

Book Description
The increasing interest in graphene, due to its unique properties and potential applications, is sparking intense research into chemically derived graphene. This book provides a comprehensive overview of the recent and state-of-the-art research on chemically derived graphene materials for different applications. Starting with a brief introduction on chemically derived graphene, subsequent chapters look at various fascinating applications such as electrode materials for fuel cells, Li/Na-ion batteries, metal–air batteries and Li-S batteries, photocatalysts for degradation of pollutants and solar-to-fuels conversion, biosensing platforms, and anti-corrosion coatings. The emphasis throughout this book is on experimental studies and the unique aspects of chemically derived graphene in these fields, including novel functionalization methods, particular physicochemical properties and consequently enhanced performance. With contributions from key researchers, the book provides a detailed resource on the latest progress and the future directions of chemically derived graphene for students and researchers across materials science, chemistry, nanoengineering and related fields.

Book Description
The chapters of this volume represent the invited papers delivered at the 3rd International Conference on Multiphoton Processes (ICOMP III) held in Iraklion, Crete, Greece, September 5-11, 1984. The invited papers at a conference like ICOMP cannot possibly cover the whole field which has grown to immense proportions in recent years, overlapping with such diverse areas as atomic and molecular spectroscopy, plasma physics, nonlinear optics, quantum optics, etc. We believe these contributions represent that part of the research activity which has been attracting the most interest in the past year or so, as well as reviews of some of the more established topics. Even within this scope, and given the confines imposed by the fi nite duration of a conference, important and timely topics are inevitably left out. But then, there will be ICOMP IV. The collection of articles in this volume, combined with extensive ref erences to related work given by the authors, should provide an introduc tion to the major problems of the field and its state of the art. The chapters have been arranged according to thematic proximity, beginning with atoms, and continuing on with molecules and surfaces. This classi fication, however, would not cover all the subject matter even within the limited scope of the conference and of this volume.

Book Description
El Método de los Elementos Finitos (MEF) es sin duda una de las herramientas más utilizadas actualmente en el ámbito del análisis y diseño de sistemas mecánicos. Permite validar y optimizar diseños de forma rápida y versátil, reduciendo la necesidad de costosas campañas experimentales y ofreciendo al diseñador información muy valiosa sobre el comportamiento del sistema y la influencia que tienen en él aspectos como la geometría, el material, la naturaleza de las cargas, etc. Basado en la extensa experiencia de los autores tanto docente como investigadora y en trabajos para empresas, este libro muestra cómo emplear el método para estudiar problemas reales de diseño mecánico. Con un enfoque teórico-práctico, está dirigido a alumnos del Grado de Ingeniería Mecánica o del Grado de Ingeniería en Tecnologías Industriales con el objetivo de dotarles de las nociones básicas teóricas y prácticas a la hora de afrontar un análisis mecánico mediante este método. La guía se ha dividido en dos partes claramente diferenciadas: En la primera parte se explican los conceptos básicos del MEF, siempre desde un punto de vista eminentemente práctico y con numerosos ejemplos ilustrativos. En la segunda parte se presenta una serie de ejemplos de aplicación de análisis por Elementos Finitos de distintos sistemas mecánicos: rodamientos, rótulas, implantes dentales, uniones atornilladas, etc. Para cada caso se describe cuál el problema que debe resolverse y se explican las características del modelo que se ha desarrollado para lograr los resultados requeridos. Sobre la base de los conceptos presentados en la primera parte del libro, en cada ejemplo se discute sobre si el modelo debe ser tridimensional o bidimensional, qué tipo de elemento habrá que utilizar y cómo será la malla, cómo se aplicarán las cargas y las condiciones de contorno, si bastará con hacer un análisis lineal o será necesario uno no lineal, cuál será el nivel de precisión de los resultados según el modelo empleado y la naturaleza propia del problema. El fin de esta guía práctica es precisamente dotar al futuro analista de Elementos Finitos de los conocimientos necesarios para que sea capaz de desarrollar el mejor modelo para dar respuesta a un problema particular.

Book Description
Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand for natural dyes as natural dyes exhibit better biodegradability and generally have a higher compatibility with the environment. However, one of the limitations on the use of natural dyes or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw material). Therefore, the exploitation of other biological sources such as fungi, bacteria and cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins offer the advantage in terms of production compared to pigments extracted from vegetables or animals, due to its simple cell and fast culturing technique. This book offers interesting insight into initial works carried out to demonstrate the potential use of bacterial pigment as colorant for various applications.
