Over the millennia, the drainageway we now call the Santa Cruz River has seen many ebbs, flows, and floods. Throughout its long history, the river has meandered. It has flowed on the surface. It has carved deep fissures, and it has widened and narrowed.As readers of Requiem for the Santa Cruz learn, these are events that also have taken place in historic times. Authored by an esteemed group of scientists, Requiem for the Santa Cruz thoroughly documents this river, which flows through Tucson, Arizona, as a prime example of arroyo cutting, a process where heavy rains cut down through rock to create deep channeling. Each chapter provides a unique opportunity to chronicle the arroyo legacy, evaluate its causes, and consider its aftermath. Using more than a century of observations and collections, the authors reconstruct the physical, biological, and cultural circumstances of the river's entrenchment, widening, and subsequent partial filling. Today, communities everywhere face this conundrum: do we manageephemeral rivers through urban areas for flood control, or do we attempt to restore them to some previous state of naturalness? Requiem for the Santa Cruz carefully explores the channel-change legacy, the efficacy of attempts to stabilize it, and the nascent attempts at river restoration to give a long-term perspective on management of rivers in arid lands. Tied together by authors who have committed their life's work to the study of arid-land rivers, this book offers a touching and scientifically grounded requiem for the Santa Cruz and every southwestern river"--
Completely re-written with two new co-authors who provide expertise in physical chemistry and engineering, the Sixth Edition of this textbook/reference explores the entire scope of the ice cream industry, from the chemical, physical, engineering and biological principles of the production process, to the marketing and distribution of the finished product. This Sixth Edition builds on the strengths of previous editions with its coverage of the history, production and consumption, composition, ingredients, calculation and preparation of mixes, equipment, processing, freezing, hardening, storage, distribution, regulations, cleaning and sanitizing, safety, and quality of ice cream and related frozen desserts.
A productive dairy industry is vital to providing safe, high-quality milk that fulfills the nutritional needs of people of all ages around the world. In order to achieve that goal, Campbell and Marshall present a timely, lucid, and comprehensive look at today’s dairy industry. Dairy Production and Processing offers not only a fundamental understanding of dairy animals, dairy products, and the production aspects of each, but also a wealth of applied information on the scope of the current milk and milk products industry. The application of basic sciences and technologies throughout the text will serve students well not only as they learn the first principles of dairy science, but also as a professional reference in their careers. Study questions can be found at the conclusion of each chapter, along with relevant and informative websites. An extensive glossary is provided to enable readers to expand their knowledge of selected terms. Topics found in this instructive and insightful text include: • an overview of the dairy industry, • dairy herd breeding and records, • the feeding and care of dairy cattle, sheep, goats, and water buffalo, • important principles of milking and milking facilities, • dairy farm management, • milk quality and safety, and • the production of milk and milk products.

At the beginning of the Civil War, Georgia ranked third among the Confederate states in manpower resources, behind only Virginia and Tennessee. With an arms-bearing population somewhere between 120,000 and 130,000 white males between the ages of 16 and 60, this resource became an object of a great struggle between Joseph Brown, governor of Georgia, and Jefferson Davis, president of the Confederacy. Brown advocated a strong state defense, but as the war dragged on Davis applied more pressure for more soldiers from Georgia. In December 1863, the state's general assembly reorganized the state militia and it became known as Joe Brown's Pets. Civil War historians William Scaife and William Bragg have written not only the first history of the Georgia Militia during the Civil War, but have produced the definitive history of this militia. Using original documents found in the Georgia Department of Archives and History that are too delicate for general public access, Scaife and Bragg were granted special permission to research the material under the guidance of an archivist and conducted under tightly controlled conditions of security and preservation control.
An absorbing celebration of the ecology, biology and cultural history of the rich hedgerow heritage in the British Isles. Much of the UK is intensively farmed, and in such landscapes hedges are often the only refuge for wildlife. In addition to providing shelter, protection and food for animals, they also connect and bind together the patches of habitat that do remain, as well as playing vital roles in soil conservation and flood prevention – in short, they are vital for nature's recovery. In Hedges, Robert Wolton brings together decades of research, while also incorporating personal experiences from his farm in Devon, to explore the ecology, nature conservation and wider environmental values of our hedges. From improving water quality and producing wood fuel as a renewable energy source to the use of hedges in boosting crop pollination, this engaging and authoritative book will help to inspire people to value and look after the remarkably rich hedgerow heritage we have in the British Isles. Containing more than 300 photographs and figures, this latest addition to the British Wildlife Collection is a comprehensive commentary on hedges and our relationship with them.
Introducing Biological Rhythms is a primer that serves to introduce individuals to the area of biological rhythms. It describes the major characteristics and discusses the implications and applications of these rhythms, while citing scientific results and references. Also, the primer includes essays that provide in-depth historic and other background information for those interested in more specific topics or concepts. It covers a basic cross-section of the field of chronobiology clearly enough so that it can be understood by a novice, or an undergraduate student, but that it would also be sufficiently technical and detailed for the scientist.
