Book Description
K.J.Ives Professor of Public Health Engineering University College London Industrial application of the use of bubbles to float fine particles in water began before the beginning of this century, in the field of mineral processing. Such bubble flotation was applied very little outside mineral processing, until about 1960 when the dissolved air process, which has already had some success in the pulp and paper industry, was applied to water and wastewater treatment. The subsequent two decades saw not only a growth development for water and wastewater treatment, but also a growing cognisance of the similarities that existed with mineral processing flotation. Therefore the time seemed ripe in 1982 for a joint meeting between experts in these two major fields of flotation to put together the Scientific Basis of Flotation in the form of a NATO Advanced Study Institute. Attended by about 60 specialists, mainly post doctoral, from 17 countries, this Study Institute in residence for two weeks in Christ's College, Cambridge (UK) heard presentations from several international experts, principally the 8 co-authors of this book. The integration of the various scientific disciplines of physics, physical chemistry, colloid science, hydrodynamics and process engineering showed where the common basiS, and occasional important differences, of flotation could be applied to mineral processing, water and wastewater treatment, and indeed some other process industries (for example: pharmaceuticals, and food manufacture).

Book Description
Proceedings of the XIV World Meeting of the International Society for the Research on Aggression: Prevention and Control of Aggression and the Impact on its Victims, held in July 9-14, 2000, in Valencia, Spain. Aggression is an aspect of human society that has interested scientists for many decades, and their work has provided important knowledge about its causes and way to prevent and control this behavior. However, not only scientists but many professionals working in the wide spectrum of society, from family to international policy, are interested in having programs of interventions capable of reducing aggression and violence in our society. This comprehensive book is a compendium of most research approaches that are currently taking place in the field of aggression, focusing on the interventions to control and prevent this behavior and the impact on its victims. The chapters of the book include biological approaches to aggression, such as neuroanatomy, neurochemistry, neuroendocrinology, genetics and psychopathology; information about aggression in children and adolescents in different settings such as family, school and community; characteristics if aggression in specific relationships such as marital and sexual, and specific settings such as bars, prisons and traffic; and cultural approaches to aggression, social prejudice, war and programs of peace. Furthermore, a small number of representative chapters about victims are included, ranging from the impact of aggression on behavior and physiology in animal models to victims of war. As this book highlights, the interventions to prevent and control aggression have to be diverse (highly heterogenic) in order to deal with all aspects of human beings and society, ranging from pharmacological control in individuals to programs of peace to promote respect among people and among nations. Scientists, academics and professionals dealing with any facet of aggression and its impact on our society will obtain in this book information about the complexity of this research field and the ways to approach our objective: eliminate aggression from the human behavioral repertoire.

Book Description
In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation. To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world. In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.

Book Description
The collection of Barbara and Lawrence Fleischman of New York is one of the most important private collections of ancient Greek and Roman art in the United States and among the most important in the world. Composed of approximately three hundred objects from the Bronze Age to the Late Antique, it includes bronze statuettes, marble sculpture, vases, jewelry, lamps and candelabra, keys, weights, and silver bowls and utensils. The Fleischmans have a particular fascination with pieces associated with everyday life in antiquity, since these objects evoke a human connection to the past. They are also drawn to pieces that exemplify the human propensity to transform a functional object into a thing of beauty. Not only has their emotional response to an object’s aesthetic appeal or its historical significance guided them in their forty years of collecting, personal interests have been at work as well. The large number of pieces related to the theater or representing theatrical subjects reflects Barbara Fleischman’s lifelong love of that art. A Passion for Antiquities contains photographs and extensive catalogue entries on the objects included in the exhibition at the J. Paul Getty Museum and the Cleveland Museum of Art. Eighteen contributors provide art historical and descriptive information about each piece. The objects not selected for the exhibition are detailed in a checklist that specifies their origins, dates, media, and sizes. This book is the first major reference on the entire collection, since most of the objects have never before been publicly shown. To facilitate finding specific objects or groups of objects, the book is organized first chronologically and then by medium. Bibliographic sources for each entry cite both publications where the specific work is discussed as well as references to related scholarship. Karol Wight provides a chronological overview of the collection, and Oliver Taplin relates selected pieces to the development of Greek theater. The exhibition of Barbara and Lawrence Fleischman’s collection and this catalogue allow us to enter into their minds and emotions so that, for a time, we can share their passion for antiquities.

Book Description
After more than a decade of successful application of cardiac pace makers in the therapy of cardiac rhythm disorders, technological and clinical experience has reached a level, at which a technical survey of this field should be of general interest and might promote the further improvement of pace maker therapy. The papers contained in this book were presented at the International Symposium on Advances in Pacemaker Technology, held at Erlangen on Sep tember 26 and 27,1974 under the auspices of the Societas Physica Medica Erlangensis. One of the traditional aims of the Societas has been the advance ment of diagnosis and therapy by the adaptation of medical skill to modern technology and scientific engineering conceptions. The major objective of this book is to present, in expanded form, the lectures given by internationally known basic and clinical researchers in the field of artificial pacing of the heart and to make that information available to a wider public. The experience discussed covers the principles and main methods of pacing using implantable and external, fixed rate, R-wave or P-wave triggered pacemakers with electrodes placed in the myocardium either surgically or transvenously, and powered by zinc-mercury oxide or rechargeable batteries. Particular emphasis was put on problems of pressing importance at the present time, such as the increase of pacemaker longevity with lithium iodide and nuclear-powered batteries or improved electrodes, as well as the postoperative management of a steadily increasing number of pacemaker patients.

Book Description
This comprehensive review of existing and potential anticancer drugs and therapies by leading researchers from academia, government laboratories, and pharmaceutical companies offers essential insight into what has been accomplished and where the experimental therapy of cancer is going. The authoritative contributors illuminate the current status of the major molecules of cancer treatment, ranging from the nitrogen mustards through platinum complexes to interferons, cytokines, growth factors and their inhibitors, and on to immunotoxins, antisense oligonucleotides, and gene therapy. A companion volume by the same editor (Anticancer Drug Development Guide: Preclinical and Clinical Screening and Approval) details the processes by which new anticancer drugs are approved. These two volumes in the Cancer Drug Discovery and Development series reveal how and why molecules become anticancer drugs and thus offer a blueprint for the present and the future of the field.
