Book Description
Much discussion has been held regarding the merits of laboratory decay tests compared with field tests to evaluate wood preservatives. In this study, procedural aspects of soil jar decay tests with 1 cm 3 blocks were critically examined. Differences among individual bottles were a major source of variation in this method. The reproducibility and sensitivity of the soil-jar method using small blocks must be further characterized before it can be accepted as a standard protocol for evaluating preservative-treated wood.

Book Description
In recent years wood strength researchers have begun to replace experimental unit allocation via random sampling with allocation via sorts based on nondestructive measurements of strength predictors such as modulus of elasticity and specific gravity. Although this procedure has the potential of greatly increasing experimental sensitivity, as currently implemented it can easily reduce sensitivity. In this paper we discuss the problem and we present solutions. Given the existence of nondestructive measurements of strength predictors, our methods can be used to reduce sample sizes. We have written a public domain computer program that implements the methods.

Book Description
Once again the present volume contains the majority of the papers presented at the Third Pan-American Biodeterioration Society Meeting held at The George Washington University, Washington, D.C., USA, on August 3, 4, 5, and 6, 1989. The sponsors for this symposium included The George Washington University, The Smithsonian Institution, The Virginia Department of Health, The University of Connecticut, The National Institute for Occupational Safety and Health, Clark Atlanta University, Ball State University, the U.S. Naval Research Laboratory, the Agriculture Research Service/U. S. Department of Agriculture, the University of Georgia, the Metropolitan Museum of Art, Morehouse College, the University of Texas at Houston, North Carolina State University, the U.S. Food and Drug Administration, and the Forest Service/U.S. Department of Agriculture. The program was developed by members of the Program, Planning, and Organizing Committee. Leading scientists in specific topic areas were invited. Also we accepted contributed papers from individuals and laboratories actively involved in relevant areas of research and study. The participation of internationally established scientists was encouraged. The Society CPABS) tried to ensure that the program reflected current developments, informed reviews, embryonic and developing areas, and critical assessment for several aspects of the present state of knowledge as it relates to the major sections of the proceedings. Obviously, not all aspects of biodeterioration or biodegradation are represented.

Book Description
My professional interest in antimicrobial agents and contamination control goes back 50 years to my tour as a microbiologist in a field hospital in Europe during World War II. With no experience and relying solely on a military handbook, I prepared thermometer trays with jars of blue bichloride of mercury and pink isopropyl alcohol. A preliminary typhoid diagnosis of one of our cooks resulted in the need for lab testing. His stool specimen and its subsequent disposal was my problem. My handbook said bum it. So burn it T did, in a five-gallon can with gasoline. Flames shot up almost six feet, and my next mistake was to extinguish them with carbon tetrachloride. This resulted in the production of lethal phosgene gas. The hospital had a near disaster. I could say that at that moment I vowed to write a how-to book so that such stupidities could be avoided. Nevertheless, when I was offered the opportunity to edit this book I thought back on the need for a real, practical treatment of my subject. This book, then, is a practical handbook for technical service personnel and scientists who are not necessarily specialists in microbiology. It provides information on suitable antimicrobial agents appropriate to their particular problem-solving needs and information on the microbial groups contributing to the specific problem, their ecologies, and strategies for controlling their access to the area or material of interest.
