Book Description
In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Book Description
This reference book describes how bioprocessing and biotechnology could enhance the value extracted from wood-based lignocellulosic fiber by employing both biochemical and thermochemical conversion processes. It documents recent accomplishments and suggests future prospects for research and development of integrated forest biorefineries (IFBR) as the path forward for the pulp, paper and other fiber-processing industries. This is the only book to cover this area of high economic, social, and environmental importance. It is aimed at industrialists and academics from diverse science and engineering backgrounds including chemical and biotechnology companies, governmental and professional bodies, and scholarly societies. The Editor and contributors are internationally recognized scientists and many are leaders in their respective fields. The book starts with an introductory overview of the current state of biorefining and a justification for future developments. The next four chapters deal with social, economic and environmental issues related to regulations, biomass production and supply, process modelling, and life cycle analysis. Subsequent chapters focus on the extraction of biochemicals from biomass and their potential utilization to add value to the IFBR prior to pulping. The book then presents, compares and evaluates two types of forest biorefineries based on kraft and organosolv pulping. Finally, the book assess the potential of waste biomass and streams, such paper mill sludge and black liquor, to serve as feedstock for biofuel production and value-added biomaterials through both the biochemical and thermochemical routes of biomass bioprocessing. The economics of the described IFBR processes and products, and their environmental impact, is a major focus in most of the chapters. Practical examples are presented where relevant and applicable.

Book Description
This book will present the papers delivered at the first U.S. conference devoted exclusively to global optimization and will thus provide valuable insights into the significant research on the topic that has been emerging during recent years. Held at Princeton University in May 1991, the conference brought together an interdisciplinary group of the most active developers of algorithms for global optimization in order to focus the attention of the mathematical programming community on the unsolved problems and diverse applications of this field. The main subjects addressed at the conference were advances in deterministic and stochastic methods for global optimization, parallel algorithms for global optimization problems, and applications of global optimization. Although global optimization is primarily a mathematical problem, it is relevant to several other disciplines, including computer science, applied mathematics, physical chemistry, molecular biology, statistics, physics, engineering, operations research, communication theory, and economics. Global optimization problems originate from a wide variety of mathematical models of real-world systems. Some of its applications are allocation and location problems and VLSI and data-base design problems. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Description
This bilingual publication results from a four-day symposium aimed at capturing the general directions and analytical issues that characterize approaches to sustainable use in Africa. The papers included in this work are organized under four major headings: modes of use, devolution, scale issues and external issues. Authors explore these themes through the use of case studies and the description of specific regional experiences. External issues are further explored in a series of commissioned policy papers which have also been included.

Book Description
Dans ce travail de recherche, nous proposons une approche d'optimisation multicritères basée sur la simulation pour la conception optimale des chaînes logistiques dans un contexte dynamique et incertain. Cette approche comprend un module d'optimisation basé sur des algorithmes génétiques multicritères et un module de simulation permettant l'évaluation de la chaîne étudiée au cours de l'optimisation. L'optimisation concerne à la fois la configuration de la chaîne logistique et le système de pilotage de ses différentes activités (approvisionnement, production, stockage, transport, etc.). Ce système est caractérisé par des règles opérationnelles et leurs paramètres de contrôle pour la prise de décision durant la simulation. L'algorithme génétique explore les solutions candidates intéressantes (configuration de la chaîne + règles de pilotage) dont les performances sont automatiquement évaluées par le simulateur. La paramétrisation du module de simulation prend en compte les incertitudes liées à la demande, à la production, au stockage et à la distribution. Pour la validation de notre approche, deux cas d'études, proposés respectivement par deux partenaires du projet européen ONE de l'industrie automobile et textile, sont présentés. L'objectif du premier cas d'étude est de reconfigurer une partie du réseau actuel de production et de distribution de notre partenaire automobile. Proposé par notre partenaire de l'industrie textile, le deuxième cas d'étude est dédié au problème de choix des fournisseurs dans un environnement dynamique et stochastique. L'objectif est de déterminer la meilleure sélection des fournisseurs, des modes de transport utilisés ainsi que certains paramètres de contrôle liés au pilotage de la chaîne étudiée
