Download or read book Urea written by Carla Maria Muñoz and published by Nova Science Publishers. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is solid, colourless, and odourless and highly soluble in water. Urea is widely used in fertilisers as a convenient source of nitrogen and also an important raw material for the chemical industry. In this book, the authors discuss the synthesis, properties and uses of urea. Topics included in this compilation are the production of granular urea as nitrogenous fertiliser; urea and urea transporter physiology; urea transport in fungi and plants; urea used as the neutralising agent for homogenous precipitation; the effect of urea on polymer films, natural fibres wood and jute plastic composites; pharmacological recognition of urea derivatives in brain disorders; non-bonding properties of urea; valproyl urea; and urea as an effective therapeutic option syndrome of inappropriate antidiuretic hormone secretion (SIADH).

This book was released on 2014-03-14 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts presents a complete overview of the selective catalytic reduction of NOx by ammonia/urea. The book starts with an illustration of the technology in the framework of the current context (legislation, market, system configurations), covers the fundamental aspects of the SCR process (catalysts, chemistry, mechanism, kinetics) and analyzes its application to useful topics such as modeling of full scale monolith catalysts, control aspects, ammonia injections systems and integration with other devices for combined removal of pollutants.

Download or read book Urea Transporters written by Baoxue Yang and published by Springer. This book was released on 2014-10-08 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanisms and physiological functions of urea transporters across biological membranes are subjects of long-standing interests. Although urea represents roughly 40% of all urinary solutes in normal human urine, the handling of urea in the tissues has been largely neglected in the past and few clinical or experimental studies now report data on urea. Most recent physiological text books include chapters on water and electrolyte physiology but no chapter on urea. Our aim in writing this book is to stimulate further research in new directions by providing novel and provocative insights into the further mechanisms and physiological significance of urea metabolism and transport in mammals. This book offers a state-of-the-art report on recent discoveries concerning urea transport and where the field is going. It mainly focuses on advances made over the past 20 years on the biophysics, genetics, protein structure, molecular biology, physiology, pathophysiology and pharmacology of urea transport in mammalian cell membranes. It will help graduate students and researchers to get an overall picture of mammalian urea transporters and may also yield benefits for pharmaceutical companies with regard to drug discovery based on the urea transporter. Baoxue Yang is a professor and vice chairman of the Department of Pharmacology, Peking University. He is also an adjunct professor of Jilin University and a visiting professor of Northeast Normal University. Prof. Yang has been researching urea transporters for nearly 20 years and has published more than 70 original research articles in this field.

Download or read book Urea as a Protein Supplement written by Michael H. Briggs and published by Elsevier. This book was released on 2014-05-16 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urea as a Protein Supplement presents the significant advances that have been made in ruminant nutrition. This book examines the role of the rumen flora and fauna as synthesizers of protein from non-protein nitrogen sources such as ammonium compounds and urea. Organized into four parts encompassing 23 chapters, this book starts with an overview of the use of urea and other non-protein nitrogen sources in ruminant nutrition. This text then explores the various methods that may be used for the preparation of urea, which involves the dehydration of ammonium carbamate produced by the reaction of carbon dioxide and ammonia at high pressure and temperature. Other chapters consider the ways in which urea could be utilized to increase protein supplies. The final chapter deals with the hydrolysis of urea by urease to ammonia and carbon dioxide, which has been used as a method for determining urea for many years. Agricultural scientists and farmers will find this book useful.

Download or read book Newton s Apple and Other Myths about Science written by Ronald L. Numbers and published by Harvard University Press. This book was released on 2015-11-04 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Guardian “Favourite Reads—as Chosen by Scientists” Selection “Tackles some of science’s most enduring misconceptions.” —Discover A falling apple inspired Isaac Newton’s insight into the law of gravity—or did it really? Among the many myths debunked in this refreshingly irreverent book are the idea that alchemy was a superstitious pursuit, that Darwin put off publishing his theory of evolution for fear of public reprisal, and that Gregor Mendel was ahead of his time as a pioneer of genetics. More recent myths about particle physics and Einstein’s theory of relativity are discredited too, and a number of dubious generalizations, like the notion that science and religion are antithetical, or that science can neatly be distinguished from pseudoscience, go under the microscope of history. Newton’s Apple and Other Myths about Science brushes away popular fictions and refutes the widespread belief that science advances when individual geniuses experience “Eureka!” moments and suddenly grasp what those around them could never imagine. “Delightful...thought-provoking...Every reader should find something to surprise them.” —Jim Endersby, Science “Better than just countering the myths, the book explains when they arose and why they stuck.” —The Guardian
