Urea

Urea PDF Author: Carla Maria Muñoz
Publisher: Nova Science Publishers
ISBN: 9781622570324
Category : Urea
Languages : en
Pages : 0

Book Description
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).

Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts

Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts PDF Author: Isabella Nova
Publisher: Springer Science & Business Media
ISBN: 1489980717
Category : Science
Languages : en
Pages : 715

Book Description
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.

Newton’s Apple and Other Myths about Science

Newton’s Apple and Other Myths about Science PDF Author: Ronald L. Numbers
Publisher: Harvard University Press
ISBN: 0674967984
Category : History
Languages : en
Pages : 304

Book Description
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

Uremic Toxins

Uremic Toxins PDF Author: Severin Ringoir
Publisher: Springer Science & Business Media
ISBN: 1468454455
Category : Science
Languages : en
Pages : 292

Book Description
The present book contains the Proceedings of a two day Symposium on Uremic Toxins organized at the University of Ghent in Belgium. A series of guest lectures, free communications and posters have been presented. An international audience of 163 scientists from 16 nationalities listened to and discussed extensively a spectrum of topics brought forward by colleagues and researchers who worked for many years in the field of Uremic Toxins. There is a striking contrast between all the new dialysis strategies available in the work to "clean" the uremic patients and the almost non-progression of our knowledge on uremic toxins in the past decade. In this sense the symposium was felt by all participants as a new start for the research in the biochemical field of the definition of uremia. If the present volume would stimulate new work in this field in order to define uremia, or identify the uremic toxins, the purpose of the organizers would be maximally fulfilled.

Urea Transporters

Urea Transporters PDF Author: Baoxue Yang
Publisher: Springer
ISBN: 9401793433
Category : Science
Languages : en
Pages : 267

Book Description
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.
