Crop Circles
Throughout the world, mysterious patterns have almost magically started appearing in fields--baffling the farmers who own the land and the scientists who examine them. What are these fantastic geometric figures? Who (or what) is creating them? Two journalists specializing in crop circle research provide revealing answers in this bestselling and visually stunning study. A spectacular 30-page pictorial, which presents an eye-catching survey of the contin-uing phenomenon, will fascinate believers and non-believers alike with its surprising beauty, variety, and complexity.
Kant and Eighteenth-Century German Philosophy
The purpose of this anthology is to bring together in one volume some of the texts published in the series "Werkprofile", which focus on Kant’s relationship to his philosophical contemporaries and predecessors, and to make them accessible to a wider audience in English. In doing so, the volume is aimed at those who have an interest in better understanding the premises of Kant's philosophy, its historical context, and the development of many of Kant’s fundamental ideas. As it is often hard to glean philosophical motivation directly from reading Kant’s texts, understanding Kant’s commitment to answering certain questions and his silence on others, requires a historical approach. This b...
Metal Ions in Biological Systems
This volume first considers the categories of zinc metalloenzymes, together with models of the enzymic metal-ion binding sites. It covers the nutritional aspects of zinc: its absorption and excretion, its influence on the activity of enzymes and hormones, and the zinc deficiency syndrome.
Crop Circles
Put on your detective hat and uncover the facts and myths about crop circles. Topics discussed include early crop circle sightings and the theories behind them, design details, alien creation theories, power of thought theories, relationship to water theories, microwave energy theories, human creation theories, scientific investigations, hoaxers, and crop circles today. Features include a Tools and Clues section that highlights research tools, technology, and investigative methods, a timeline, a glossary, selected bibliography, further readings, places to visit, source notes, and an index. Aligned to Common Core Standards and correlated to state standards. Essential Library is an imprint of Abdo Publishing, a division of ABDO.
Metal Ions in Biological Systems
"Focuses on the vibrant area of probing enzymes or proteins by metal ions and small complexes. Offers a summary of the basic characteristics of the amide bond, emphasizing its proton and metal ion interactions, including a quantitative analysis of its hydrolysis and formation."
Metal Ions in Biological Systems, Volume 43 - Biogeochemical Cycles of Elements
Metal Ions in Biological Systems is devoted to increasing our understanding of the relationship between the chemistry of metals and life processes. The volumes reflect the interdisciplinary nature of bioinorganic chemistry and coordinate the efforts of researchers in the fields of biochemistry, inorganic chemistry, coordination chemis
Trace Elements in Man and Animals 6
This book is the published proceedings of the Sixth International Symposium on Trace Element Metabolism in Man and Animals. The Symposium was held at the Asilomar Conference Center in Pacific Grove, California, U.S.A. from May 31 through June 5, 1987. The decision to hold TEMA-6 at Asilomar was made at TEMA-5 in 1985. The International Guidance Committee decided to hold the meeting in California in part to recognize the significant cont~i butions made to the field of trace element metabolism by Professor Lucille S. Hurley. As such, she was the obvious choice as chair of the local organ izing committee. One of the principal goals of Professor Hurley was that TEMA-6 serve as a forum for discussing the use and application of newer methodologies, such as molecular biology, computer modelling and stable isotopes, in studies of trace element metabolism. Based on the comments which the local organizing committee has received, this goal was achieved. The Symposium was attended by 275 scientists from 32 countries covering 6 continents. Twenty-five speakers were chosen for our plenary sessions.
