Since the first works introducing the aluminum intercalated clay family in the early 1970s, interest in the synthesis of pillared interlayered clays has increased tremendously, especially research into the properties and applications of new synthesis methods. The need for solids that could be used as cracking catalysts with larger pores than zeolitic materials has spurred the synthesis of new porous materials from clays. Pillared Clays and Related Catalysts reviews the properties and applications of pillared clays and other layered materials used as catalysts, focusing on: the acidity of pillared clays and the effect it has on catalytic performance the use of pillared clays as supports for catalytically active phases, and the use of the resulting solids in environmentally friendly reactions the applications of the selective reduction of NOx the comparison between the reactions of pillared clays and anionic clays.
This is the first text to focus on the comparative value of species, examining the relative consequences of individual extinctions. It attempts to provide ecologically based guidance to conservationists struggling with limited resources and compelled to set priorities for their work.
We all like to eat, but we are doing it wrong, and it gets worse every day. Deceived by the food industry, advertising, culinary fake news, and Aunt Bertha's nutrition advice, with every bite we are making nefarious decisions that steal our energy and make us both ill and fat. How can we stop this cycle? Who should we believe? How can we change our habits without becoming rigid and boring? In this book, renowned doctor Carlos Jaramillo offers robust answers to these questions and states that the key to optimal weight and health is our metabolism. Understanding what it is, how it operates, and what we can do to make it work in our favor is fundamental. And it is what the reader will accomplish on these pages.
Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from t...
This book constitutes the refereed proceedings of the 40th European Conference on IR Research, ECIR 2018, held in Grenoble, France, in March 2018. The 39 full papers and 39 short papers presented together with 6 demos, 5 workshops and 3 tutorials, were carefully reviewed and selected from 303 submissions. Accepted papers cover the state of the art in information retrieval including topics such as: topic modeling, deep learning, evaluation, user behavior, document representation, recommendation systems, retrieval methods, learning and classication, and micro-blogs.
Coffee – Production and Research presents a diversity of important issues related to coffee, with an emphasis on the science of coffee growing. Coffee is one of the highest value commodities traded worldwide. Cultivated and consumed widely, it generates progress for both the economy and society. Divided into six sections, this book examines two coffee species of commercial importance, Coffea arabica L. and Coffea canephora Pierre ex. A. Froehner. Chapters cover such topics as biotechnology, growing, harvesting, post-harvest handling, quality, chemistry, commercialization, and byproducts of coffee.
Basic Pharmacology, Third Edition aims to present accounts of drug actions and their mechanisms in a compact, inexpensive, and updated form, and explain the basis of the therapeutic exploitation of drugs. This book is divided into sections that follow a particular theme and is introduced by the relevant pharmacological general principles. In each section, the major groups of drugs related to the theme are discussed with detailed expositions of the important “type substances. Drugs of lesser importance are placed in proper context. A list of abbreviations that are referenced throughout the book is provided after the introduction. An index is also included at the end. This edition is designed to help students taking pharmacology, including medical students of subjects affiliated to medicine, to appreciate the rationale underlying the uses of drugs in therapeutics.
His name is inextricably linked with a single work, A Sand County Almanac, a classic of natural history literature and the conservationist's bible. This book brings together the best of Leopold's essays.
This definitive edition of Columbus's account of the voyage presents the most accurate printed version of his journal available to date. Unfortunately both Columbus's original manuscript, presented to Ferdinand and Isabella along with other evidence of his discoveries, and a single complete copy have been lost for centuries. The primary surviving record of the voyage-part quotation, part summary of the complete copy-is a transcription made by Bartolome de las Casas in the 1530s. This new edition of the Las Casas manuscript presents its entire contents-including notes, insertions, and canceled text-more accurately, completely, and graphically than any other Spanish text published so far. In a...
