Immunochemistry has broad applications for a wide variety of environmental contaminants. However, the potential for applying immunochemical methods to environmental measurements is just beginning to be realized. Immunochemical methods are based on specific antibodies combining with their target analyte(s). Many specific antibodies have been produced for targets of environmental and human health concern. Such antibodies can be configured into various analytical methods. The most popular Immunochemical technique in environmental analyses today is immunoassay. Immunoassays have been shown to detect and quantify many compounds of environmental interest such as pesticides, industrial chemicals, and products of xenobiotic metabolism. Among the most important advantages of immunoassays are their speed, sensitivity, selectivity and cost-effectiveness.

Immunochemical methods for the analysis of environmental contaminants are relatively new on the analytical chemistry scene. These methods are based on the use of a specific antibody as a detector for the analyte of interest. Immunoassays are rapid, sensitive, and selective, and are generally cost effective for large sample loads. They have been applied to diverse chemical structures (i.e., triazines, sulfonylureas, organo-phosphates, polychlorinated biphenyls, cyclodienes) and are adaptable to field use. These characteristics make immunochemical analysis a valuable tool for use by the environmental analytical chemist. This document is designed to facilitate the transfer of this valuable technology to the environmental analytical chemistry laboratory. Field personnel who may need to employ a measurement technology at a monitoring site mayalso find this manual helpful.

This book is a tutorial designed to instruct the reader in use and application of immunochemical methods of analysis for environmental contaminants. A brief introduction describes basic principles and the advantages and disadvantages of the technology, and gives a listing of references which supply more detail. Preparation of the laboratory for use of this technology and the general scientific considerations prior to using the technology are discussed. Detailed step-wise procedures are given for analysis of selected analytes, triazine herbicides, carbaryl, paraquat, and p-nitrophenols, etc. In addition to the specific immunoassay methods, a series of support techniques necessary to perform immunochemical methods are described.

This book provides specific instruction for certain analytes, but also serves to familiarize the novice reader with many generic concepts needed to successfully utilize immunochemistry technology including: applications, sampling, sample preparation, extraction, cleanup, quality assurance, methods development and optimization, data handling and troubleshooting. It is not necessary for the reader to actually perform the immunoassays given in this User's Guide to obtain familiarity with these concepts. The Guide is written so that the information presented can be applied to other immunoassays not given here. Thus, the strength of the Guide is its universal applicability to immunoassay methods.

Today, virtual worlds abound, avatars are every day occurrences, and video games are yesterday's news. But today's games are not just a pastime for millions - they are also a technological focal point for new forms of learning.

James Paul Gee and Elisabeth Hayes are leading researchers in the field of gaming, and here they argue that women gamers--a group too often marginalized--are at the forefront of today's online learning world. By utilizing the tools of gaming in ways never before imagined - actively engaging in game design, writing fan fiction, and organizing themselves into collaborative learning communities - women of all ages acquire the tools to successfully navigate the complex social, cultural, and economic problems of the 21st century.

Women are leading the way to a new understanding of online learning techniques, from cultural production to learning communities to technical proficiency in the latest software. This book draws on case studies about women who "play" the "Sims," the best selling game in history, to argue for a new general theory of learning for the 21st Century.

The authors argue that women gamers, too often ignored as gamers, are in many respects leading the way in this trend towards design, cultural production, new learning communities, and the combination of technical proficiency with emotional and social intelligence.

The 18th century was a wealth of knowledge, exploration and rapidly growing technology and expanding record-keeping made possible by advances in the printing press. In its determination to preserve the century of revolution, Gale initiated a revolution of its own: digitization of epic proportions to preserve these invaluable works in the largest archive of its kind. Now for the first time these high-quality digital copies of original 18th century manuscripts are available in print, making them highly accessible to libraries, undergraduate students, and independent scholars.Delve into what it was like to live during the eighteenth century by reading the first-hand accounts of everyday people, including city dwellers and farmers, businessmen and bankers, artisans and merchants, artists and their patrons, politicians and their constituents. Original texts make the American, French, and Industrial revolutions vividly contemporary.++++The below data was compiled from various identification fields in the bibliographic record of this title.
