This book discusses studies that have been conducted on various animal species. The book reviews the effects of pesticides through changes in behavior, the nature of morphological and biochemical lesions, as well as the tracking of the metabolic disposition of pesticides in target sites of an organism. In vitro studies provide information regarding cellular responses and biochemical lesions with pesticides. Toxicological profiles of pesticides are cited using different species of animals for in vivo and in vitro studies. This information should help scientists and decision-makers reach conclusions regarding the toxicological effects of pesticides on humans and the environment.
The future of insect control looked very bright in the 1950s and 1960s with new insecticides constantly coming onto the market. Today, however, whole classes of pesticide chemistry have fallen by the wayside due to misuse which generated resistance problems reaching crisis proportions, severe adverse effects on the environment, and public outcry that has led to increasingly stricter regulation and legislation. It is with this background, demanding the need for safer, environmentally friendly pesticides and new strategies to reduce resistance problems, that this book was written. The authors of the various chapters have a wealth of experience in pesticide chemistry, biochemical modes of actio...
Principles of Sensory Evaluation of Food covers the concepts of sensory physiology and the psychology of perception. This book is composed of 11 chapters that specifically consider the significance of these concepts in food sensory analysis. After providing a brief introduction to problems related to sensory evaluation in food industry, this book goes on examining the physiology and psychology of the senses. The succeeding chapters survey the status of methodology and appropriate statistical analyses of the results. These topics are followed by discussions on the problems of measuring consumer acceptance. Food acceptance and preference depend on human sensory responses. The remaining chapters describe the relationship between sensory characteristics and various physical and chemical properties of foods. This book will prove useful to food scientists and researchers.
The nicotinoids are the most important new class of pesticides, joining the organophosphorus compounds, methylcarbamates, and pyrethroids as the major insecticides. Recently, imidacloprid and related nicotinoids have begun replacing organophosphorus and methylcarbamate compounds as insecticides to control insect pests on major crops. Nicotinoids act on the nicotinic acetylcholine receptor, as does naturally occurring nicotine, but with remarkable effectiveness against insects while being safe for mammals; they are quickly degraded and do not persist in the environment. This volume describes the relationship of nicotinoids to botanical insecticidal alkaloids, their discovery and development as insecticides, and the prospects for their expanded use and for the development of resistance. This book is the first to provide concise, comprehensive information on nicotinoids, their chemistry, mode of action, metabolism, and application in agriculture.
Recent years have seen important developments in the computer and game industry, including the emergence of the concept of serious games. It is hypothesized that tools such as games, virtual reality, or applications for smartphones may foster learning, enhance motivation, promote behavioral change, support psychotherapy, favor empowerment, and improve some cognitive functions. Computers and games may create supports for training or help people with cognitive, emotional, or behavioral change. Games take various formats, from board games to informatics to games with interactive rules of play. Similarly, computer tools may vary widely in format, from self-help or assisted computerized training ...
This necessary desk reference for every practicing spectroscopist represents the first definitive book written specifically to integrate knowledge about group frequencies in infrared as well as Raman spectra. In the spirit of previous classics developed by Bellamy and others, this volume has expanded its scope and updated its coverage. In addition to detailing characteristic group frequencies of compounds from a comprehensive assortment of categories, the book includes a collection of spectra and a literature search conducted to verify existing correlations and to determine ways to enhance correlations between vibrational frequencies and molecular structure. Particular attention has been giv...
This money-saving package includes the 9th edition of Wong's Essentials of Pediatric Nursing - Text and Study Guide.
The third edition of this highly successful manual is not only a revised text but has been extended to meet the interpretive needs of Raman users as well as those working in the IR region. The result is a uniquely practical, comprehensive and detailed source for spectral interpretation. Combining in one volume, the correlation charts and tables for spectral interpretation for these two complementary techniques, this book will be of great benefit to those using or considering either technique. In addition to the new Raman coverage the new edition offers: * new section on macromolecules including synthetic polymers and biomolecules; * expansion of the section on NIR (near infrared region) to reflect recent growth in this area; * extended chapter on inorganic compounds including minerals and glasses; * redrawn and updated charts plus a number of new charts covering data new to this edition. This new edition will be invaluable in every industrial, university, government and hospital laboratory where infrared (FT-IR) and Raman spectral data need to be analysed.
