Functional and Ecological Xylem Anatomy


Book Description

The book will describe the xylem structure of different plant groups, and will put the findings in a physiological and ecological context. For instance, when differences in vessel diameter are featured, then there will be an explanation why this matters for water transport efficiency and safety from cavitation. The focus is on the hydraulic function of xylem, although mechanical support and storage will also be covered. Featured plant groups include ferns (which only have primary xylem), conifers (tracheid-based xylem), lianas (extremely wide and long vessels), drought-adapted shrubs as well as the model systems poplar and grapevine. The book chapters will draw on the expertise and cutting edge research of a diversified group of internationally known researchers working in different anatomical and physiological sub-disciplines. Over the last two decades, much progress has been made in understanding how xylem structure relates to plant function. Implications for other timely topics such as drought-induced forest dieback or the regulation of plant biomass production will be discussed.

A Short History of Opera


Book Description

When first published in 1947, A Short History of Opera immediately achieved international status as a classic in the field. Now, more than five decades later, this thoroughly revised and expanded fourth edition informs and entertains opera lovers just as its predecessors have. The fourth edition incorporates new scholarship that traces the most important developments in the evolution of musical drama. After surveying anticipations of the operatic form in the lyric theater of the Greeks, medieval dramatic music, and other forerunners, the book reveals the genre's beginnings in the seventeenth century and follows its progress to the present day. A Short History of Opera examines not only the standard performance repertoire, but also works considered important for the genre's development. Its expanded scope investigates opera from Eastern European countries and Finland. The section on twentieth-century opera has been reorganized around national operatic traditions including a chapter devoted solely to opera in the United States, which incorporates material on the American musical and ties between classical opera and popular musical theater. A separate section on Chinese opera is also included. With an extensive multilanguage bibliography, more than one hundred musical examples, and stage illustrations, this authoritative one-volume survey will be invaluable to students and serious opera buffs. New fans will also find it highly accessible and informative. Extremely thorough in its coverage, A Short History of Opera is now more than ever the book to turn to for anyone who wants to know about the history of this art form.







HLA and Disease Associations


Book Description

The human leukocyte antigen (HLA) or tissue types are the products of a rapidly developing field of knowledge within the last 20 years. In the early stages of the research many investigators suspected the existence of a complex series of transplantation antigens, but it was widely believed that these antigens would not be well-defined even in this century. Yet in the last two decades as many as 124 different HLA antigens determined by at least 7 very closely linked genes located on the short arm of chromosome 6 have been identified and subsequently agreed upon by an international nomenclature committee. 1 Extensive international collaboration fueled by the potential clinical application of these antigens to clinical transplantation has advanced the field rapidly. There were nine inter national histocompatibility workshops held during this period. Although iden tification of HLA antigens was of primary clinical importance in transplantation 2 and of great basic interest in human genetics and anthropology, a rather un expected bonus has been the determination that HLA antigens are associated with disease susceptibility to a greater extent than any other known genetic marker in man. In the past, many genetic polymorphisms have been suspected to be associated with diseases. The most extensively studied markers are blood groups, enzymes, and serum proteins. A comprehensive account of published studies, totalling approximately 1,000, of these markers is available in a book by Mourant et al.
