Fluorescence and phosphorescence are proving to be extremely sensitive probes for elucidating conformation of proteins and nucleic acids and for studying molecular interactions. Maryland May, 1967 v CONTENTS Introduction . * * . . . . . . . . . * . . . . . . . . . .

The ten papers presented here must be looked at in context: an effort was made to present to a largely lay audi ence a cross section of those aspects of recent advances in science and technology that were considered to haye the most striking or inclusive effects on man's view of his world.

During the past decade we have witnessed a revolution in analytical methods. Thus, I hope that there will be adequate documentation of the reliability of the methods as well as a comparison of the advantages and disadvantages of this analytical method with other classical methods.

earth, the experimental curve so plotted should have the same shape as a portion of the ap propriate theoretical curve, but with the ordinates and abscissas shifted by an amount dependent on the resistivity.

* This collection contains articles devoted to the plastic properties of monocrystals and one article devoted to the description of the latest views and experimental data on the structure and properties of grain boundaries.

This volume of Astrophysical Data deals with Planets and Stars; We then discuss everyday stars, beginning with the Sun, and continuing with basic stellar data, the brightest stars and nearby stars. Special categories of stars, such as the Wolf-Rayet stars, magnetic stars, flare stars, and RS CVn binary stars, are included.

This book is a basic BASIC programming text. Although most of the programs in this book are short (to save unnecessary typing on your part), they are the foundation for a complete understanding of BASIC programming that will enable you to build long programs de signed to do exactly what you want them to do.

Welcome to the world of computer programming. Learning to program computers simply means learning a new language-in this case, TI BASIC (for Beginner's All purpose Symbolic Instruction Code), a version of the most popular language used on today's microcomputers.

This book was written for those individuals who are concerned about the techniques and practices of plant cell cultures for horticultural crops.

It is appropriate at this time to reflect on two decades of research in biological control of weeds with fungal plant pathogens.

In the modern organic synthesis industries, one of which is the synthetic rubber industry, ever increasing use is made of physical and physicochemical methods of analysis, which sur pass chemical methods in speed, accuracy, and sensitivity.

It is not often that one has the opportunity to send a public birthday greet ing to a friend and colleague of many years, and to congratulate him on having reached the age of reason.

The papers in this book were presented at the Third International Symposium on Redox Mechanisms and Interfacial Properties of Molecules of Biological Importance held in Honolulu, Hawaii between October 19-23, 1987.

This book is about how young physicians experience training as medical specialists.

The XXX Congress of the International Union of Physiological Sciences took place in Vancouver, Canada, in July 1986; Finally, the Plenary Lectures which formed part of the opening and closing ceremonies and which deal with some aspects of Canadian physiological history, find a place here as well.

We quickly became aware of the high prevalence of such disorders, how poorly prepared we were to make accurate and re sponsible diagnosis and treatment plans, and how complicated an etiol ogical diagnosis could prove to be. As we began accumulating the information base, we became aware that this information might be of value to other physicians.

While diseases of free-ranging and captive mammalian and avian wildlife species have received considerable interest in the past 25 years, those of amphibians and reptiles (collectively, the herptiles) generally have been assigned lesser importance. how ever, predominant diseases, as well as some diseases of lesser prominence, are presented.

Phase transfer catalysis or interfacial catalysis is a syn thetic technique involving transport of an organic or inorganic salt from a solid or aqueous phase into an organic liquid where reaction with an organic-soluble substrate takes place.

This volume differs from the volume, Semiotics 1980, in that it is no longer an experimental product, but the result of a permanent commitment of the Semiotic Society of America to publish each year henceforward those papers presented at its Annual Meeting which are submitted to the Secretariat in timely and proper form.

People across the world use their langu ages to communicate about spatial orientation in problems of simple direction giving and spatial descriptions as well as problems of long range navigation.
