A System Of Shorthand First Published In 1740 Seventeenth Edition With A Preface By W B G

A collection of essays by the art historian Aby Warburg, these essays look beyond iconography to more psychological aspects of artistic creation: the conditions under which art was practised; its social and cultural contexts; and its conceivable historical meaning.

This book covers the most recent scientific and technological developments (state-of-the-art) in the field of chemical oxidation processes applicable for the efficient treatment of biologically-difficult-to-degrade, toxic and/or recalcitrant effluents originating from different manufacturing processes. It is a comprehensive review of process and pollution profiles as well as conventional, advanced and emerging treatment processes & technologies developed for the most relevant and pollution (wet processing)-intensive industrial sectors. It addresses chemical/photochemical oxidative treatment processes, case-specific treatability problems of major industrial sectors, emerging (novel) as well as pilot/full-scale applications, process integration, treatment system design & sizing criteria (figure-of-merits), cost evaluation and success stories in the application of chemical oxidative treatment processes. Chemical Oxidation Applications for Industrial Wastewaters is an essential reference for lecturers, researchers, industrial and environmental engineers and practitioners working in the field of environmental science and engineering.

From the author of No.1 international bestseller Collapse, a mesmerizing portrait of the human past that offers profound lessons for how we can live today Visionary, prize-winning author Jared Diamond changed the way we think about the rise and fall of human civilizations with his previous international bestsellers Guns, Germs and Steel and Collapse. Now he returns with another epic - and groundbreaking - journey into our rapidly receding past. In The World Until Yesterday, Diamond reveals how traditional societies around the world offer an extraordinary window onto how our ancestors lived for the majority of human history - until virtually yesterday, in evolutionary terms - and provide unique, often overlooked insights into human nature. Drawing extensively on his decades working in the jungles of Papua New Guinea, Diamond explores how tribal societies approach essential human problems, from childrearing to conflict resolution to health, and discovers we have much to learn from traditional ways of life. He unearths remarkable findings - from the reason why modern afflictions like diabetes, obesity and Alzheimer's are virtually non-existent in tribal societies to the surprising benefits of multilingualism. Panoramic in scope and thrillingly original, The World Until Yesterday provides an enthralling first-hand picture of the human past that also suggests profound lessons for how to live well today. Jared Diamond is the Pulitzer Prize-winning author of the seminal million-copy-bestseller Guns, Germs, and Steel, which was named one of TIME's best non-fiction books of all time, and Collapse, a #1 international bestseller. A professor of geography at UCLA and noted polymath, Diamond's work has been influential in the fields of anthropology, biology, ornithology, ecology and history, among others.

Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

Written for non-specialist users of electric motors and drives, this book explains how electric drives work and compares the performance of the main systems, with many examples of applications. The author's approach - using a minimum of mathematics - has made this book equally popular as an outline for professionals and an introductory student text. * First edition (1990) has sold over 6000 copies. Drives and Controls on the first edition: 'This book is very readable, up-to-date and should be extremely useful to both users and o.e.m. designers. I unhesitatingly recommend it to any busy engineer who needs to make informed judgements about selecting the right drive system.' New features of the second edition: * New section on the cycloconverter drive. * More on switched relectance motor drives. * More on vector-controlled induction motor drives. * More on power switching devices. * New 'question and answer' sections on common problems and misconceptions. * Updating throughout. Electric Motors and Drives is for non-specialist users of electric motors and drives. It fills the gap between specialist textbooks (which are pitched at a level which is too academic for the average user) and the more prosaic 'handbooks' which are filled with useful detail but provide little opportunity for the development of any real insight or understanding. The book explores most of the widely-used modern types of motor and drive, including conventional and brushless d.c., induction motors (mains and inverter-fed), stepping motors, synchronous motors (mains and converter-fed) and reluctance motors.
