This volume covers an extremely visible area of chemistry, optics, and materials science - nonlinear optics in organic materials. Starting with the basic concepts, it explores measurements and molecular engineering, and then brings you up-to-date on the current status of the field. In the final section possible future directions for research in this area are considered.

This important volume presents the pros and cons of a national service that will meet the information needs and wants of all people. In the preface, Everette E. Dennis, Executive Director of The Freedom Forum Media Studies Center, asks, "What will a true information highway -- where most citizens enjoy a wide range of information services on demand -- do to local communities, government, and business entities, other units of society and democracy itself?"
It is no longer a question of whether a vastly expanded "information highway" will be built in America. Telephone and cable companies...

"The Teacher's Grammar Book, Second Edition" introduces the various grammars that inform writing instruction in our schools, and examines methods, strategies, and techniques that constitute best classroom practices for teaching grammar and writing. Designed for students who are preparing to become English or language arts teachers, as well as for credentialed teachers who want an easy-to-use guide to questions of methods, grammar, and teaching, this overview of basic English grammar includes the following major topics: a brief history of grammar, teaching grammar, grammar and writing,...

This collection of essays was presented to David Wiggins to mark his 60th birthday and his accession to the Wykeham Chair of Logic at Oxford. The contributors, who include both long-established and younger writers, take up some of the many important philosophical debates on which Wiggins has made an impact. Their chosen topics range from ancient philosophy to contemporary questions in ethics, metaphysics and the theory of meaning. A feature of the volume is that it contains Wiggins's comments on each of the papers, and so offers an accessible guide to his present thinking.

This work by S. Wells Williams is a complete look at the Chinese Empire during the mid-nineteenth century. Subjects include the divisions of the Empire, geographical descriptions, religion and art, literature, the second war between Great Britain and China and Chinese social life.

Historically, the major emphasis on the study of purinergic systems has been predominantly in the areas of physiology and gross pharmacology. The last decade has seen an exponential in crease in the number of publications related to the role of both adenosine and A TP in mammalian tissue function, a level of interest that has evolved from a more molecular focus on the identity of adenosine and A TP receptor subtypes and the search for selective ligands and development of radioligand binding assays by Fred Bruns and colleagues (especially that for A receptors) that played z a highly...

First published in 1975, this book is a comprehensive and quantitative study of the shoot apex and leaf growth. Its central purpose is to provide precise quantitative descriptions of shoot apical systems of very diverse types. Vegetative apices are considered except for wheat for which a description of the developing inflorescence is also given. The descriptions rely on a development of the old technique of serial reconstruction, which allows the early stages in growth of leaf primordia and related tissues to be measured as volume. An important feature of the book is the numerous...
