Chemical separations are of central importance in many areas of environmental science, whether it is the clean up of polluted water or soil, the treatment of discharge streams from chemical processes, or modification of a specific process to decrease its environmental impact. This book is an introduction to chemical separations, focusing on their use in environmental applications. The authors first discuss the general aspects of separation technology as a unit operation. They also describe how property differences are used to generate separations, the use of separating agents, and the selection criteria for particular separation techniques. The general approach for each technology is to present the chemical and/or physical basis for the process and explain how to evaluate it for design and analysis. The book contains many worked examples and homework problems. It is an ideal textbook for undergraduate and graduate students taking courses on environmental separations or environmental engineering.
This book examines the evolution of American universities during the years following World War II. Emphasizing the importance of change at the campus level, the book combines a general consideration of national trends with a close study of eight diverse universities in Massachusetts. The eight are Harvard, M.I.T., Tufts, Brandeis, Boston University, Boston College, Northeastern and the University of Massachusetts. Broad analytic chapters examine major developments like expansion, the rise of graduate education and research, the professionalization of the faculty, and the decline of general education. These chapters also review criticisms of academia that arose in the late 1960s and the fate of various reform proposals during the 1970s. Additional chapters focus on the eight campuses to illustrate the forces that drove different kinds of institutions--research universities, college-centered universities, urban private universities and public universities--in responding to the circumstances of the postwar years.
Written with undergraduate students in mind, the new edition of this classic textbook provides a compact introduction to the physiology of nerve and muscle. It gives a straightforward account of the fundamentals accompanied by some of the experimental evidence upon which this understanding is based. It first explores the nature of nerve impulses, clarifying their mechanisms in terms of ion flow through molecular channels in cell membranes. There then follows an account of the synaptic transmission processes by which one excitable cell influences activity in another. Finally, the emphasis turns to the consequences of excitable activity in the activation of contraction in skeletal, cardiac and smooth muscle, highlighting the relationships between cellular structure and function. This fourth edition includes new material on the molecular nature of ion channels, the activation of skeletal muscle and the function of cardiac and smooth muscle, reflecting exciting new developments in these rapidly growing fields.
