Ed Rosenthal has long been considered the best source for reliable information about growing the controversial weed. This volume, based on his "Ask Ed" column, collects hundreds of readers' actual questions and tips on all the major concerns about cultivation, plus topics like pot etiquette, medical marijuana, and political activism. Questions are organized from seed to harvest, and cover hydroponics, lighting, nutrients, cloning, and many more topics in detail. Illustrations, tables, and a thorough index help readers quickly find the information they need.
The first book in the Marijuana Tips series, this accessible guide shows indoor cultivators how to refine their gardening techniques in order to markedly improve their crops. With an emphasis on organic methods, author DJ Short addresses every aspect of cultivation, from sprouting seeds, to lighting and temperature, to harvesting and curing. He also provides a wealth of information on marijuana breeding and plant selection.
Chronobiology is the study of timing mechanisms in biological systems as diverse as plants, animals and some micro-organisms. It includes rhythmic phenomena ranging from short period (ultradian) through daily (circadian) to long period (monthly, annual) cycles of behaviour, physiology and biochemistry. In recent years spectacular advances have been made, particularly in the field of circadian rhythms, and hardly a week passes without important papers appearing in the major scientific journals.The third edition of Insect Clocks, like its predecessors, deals with the properties and functions of clock-like processes in one of the planet's most abundant groups of organisms. The first half of the book is concerned with circadian rhythmicity, the second with annual responses such as over-wintering diapause, seasonal morphs and cold hardiness. Insect Clocks puts modern developments in these fields into a secure framework of the 'classical' literature that has defined the subject.The book is directed at active researchers in the field as well as newcomers and scientists working in many other areas of modern biology. It will also serve as a textbook for advanced and less advanced students and should find its way into university libraries wishing to keep abreast of the times.
Normative Biology, Husbandry, and Models, the third volume in the four volume set, The Mouse in Biomedical Research, encompasses 23 chapters whose contents provide a broad overview on the laboratory mouse's normative biology, husbandry, and its use as a model in biomedical research. This consists of chapters on behavior, physiology, reproductive physiology, anatomy, endocrinology, hematology, and clinical chemistry. Other chapters cover management, as well as nutrition, gnotobiotics and disease surveillance. There are also individual chapters describing the mouse as a model for the study of aging, eye research, neurodegenerative diseases, convulsive disorders, diabetes, and cardiovascular and skin diseases. Chapters on imaging techniques and the use of the mouse in assays of biological products are also included.
In this moving and provocative anthology, the bestselling author of The Book of Qualities presents poems, myths, and prayers celebrating the fundamental cycle of life--night into day, sun and moon, and dark into light. Embellished with Gendler's own evocative and brilliantly vivid art.
Hayes’ Principles and Methods of Toxicology has long been established as a reliable and informative reference for the concepts, methodologies, and assessments integral to toxicology. The new edition contains updated and new chapters with the addition of new authors while maintaining the same high standards that have made this book a benchmark resource in the field. Key Features: The comprehensive yet concise coverage of various aspects of fundamental and applied toxicology makes this book a valuable resource for educators, students, and professionals. Questions provided at the end of each chapter allow readers to test their knowledge and understanding of the material covered. All chapters have been updated and over 60 new authors have been added to reflect the dynamic nature of toxicological sciences New topics in this edition include Safety Assessment of Cosmetics and Personal Care Products, The Importance of the Dose/Rate Response, Novel Approaches and Alternative Models, Epigenetic Toxicology, and an Expanded Glossary. The volume is divided into 4 major sections, addressing fundamental principles of toxicology (Section I. "Principles of Toxicology"), major classes of established chemical hazards (Section II. "Agents"), current methods used for the assessment of various endpoints indicative of chemical toxicity (Section III. "Methods"), as well as toxicology of specific target systems and organs (Section IV. "Organ- and System-Specific Toxicology"). This volume will be a valuable tool for the audience that wishes to broaden their understanding of hazards and mechanisms of toxicity and to stay on top of the emerging methods and concepts of the rapidly advancing field of toxicology and risk assessment.
The subject of this book is neuroendocrinology, that branch of biological science devoted to the interactions between the two major integrative organ systems of animals-the endocrine and nervous systems. Although this science today reflects a fusion of endocrinology and neurobiology, this synthetic ap proach is relatively recent. At the beginning of the 20th century, when the British physiologists, Bayliss and Starling, first proposed endocrinology to be an independent field of inquiry, they went to great lengths to establish the autonomy of chemical secretions in general and their independence from nervous control in particular (Bayliss, W. M. , and Starling, E. H. , 1902, The mechanism of pancreatic secretion,]. Physiol. 28:325). They argued with Pav lov, who said that there was a strong influence of the nervous system on the gastrointestinal phenomena the endocrinologists were studying. For several decades, the English physiologists prevailed, at least in the West; and Pavlov's critique was not taken to heart by the practitioners of the newly emerging discipline of endocrinology. Through the work of Harris, the Scharrers, Sawyer, Everett, and others, there has been something of a scientific detente in the latter half of this century; the hybrid field of neuroendocrinology is now regarded as one of the corner stones of modern neural science and is of fundamental importance in basic and clinical endocrinology.
