At least 162 species of fish are known to live or spawn in the freshwaters of the Northeast, representing twenty-eight families and sixteen orders. This diversity springs from an enormous variety of freshwater habitats, including some of the largest lakes in the world; vast and complex river systems; deep, clear lakes in Maine and the Adirondack Mountains; and myriad small lakes, bogs, marshes, and streams that dot the northeast. In the most comprehensive book of its kind, Robert G. Werner offers a thorough survey and analysis, in accessible field guide form, of the region’s abundant freshwater fishes. Werner’s discussion of the geological history of the region serves as a critical background for understanding not only the fascinating habitats of fishes but also the extensive watersheds and drainages of the region. A reference list provides up-to-date sources, and the species descriptions contain the latest relevant data and research on specific fish. In addition, vivid color plates and extensive line drawings illustrate fish morphology and the distinctive natural colors of numerous species. As a standard resource, this guide will attract a wide audience. This book will be useful to biologists, ecologists, and zoologists and will have an indispensable appeal among anglers, environmentalists, and fisheries professionals.
James Bach and Robert Werner’s How to Secure Your H-1B Visa is written for both employers and the workers they hire." Andrew Hacker, "The Frenzy about High-Tech Talent", The New York Review of Books, July 9, 2015 The H-1B visa is the gateway for the world’s best and brightest to live and work in the United States as IT professionals, engineers, scientists, professors, doctors, nurses, and researchers. How to Secure Your H‐1B Visa guides employees and employers alike through the maze of H-1B laws, policies, and procedures. This road map lays out the whole H-1B process from petition to visa to status maintenance to visa extension and, ultimately, to permanent residence in the US for you and your family. It shows you step by step exactly how the H-1B process divides up between the employer and employee. It identifies the points where the two tracks converge and the H-1B employer and employee need to pull in tandem. Navigation icons tell you at a glance whether a topic concerns employees and employers equally or primarily one or the other. Sidebars highlight pitfalls, liabilities, and disasters to avoid; tips and exceptions to leverage for success; administrative and enforcement trends and late-breaking changes; and special conditions that apply to nationals of particular countries, such as India and China. Ancillary chapters cover complementary visas for family members and H-1B substitute visas for professionals with particular skill sets or from particular countries, such as Australia and Canada. The authors are Silicon Valley immigration lawyers with 60 years combined experience handling professional work visas. Whether you are an international professional desiring to work in the US for the first time, an international student in the US wishing to remain after graduation, or a hiring manager or HR specialist for a sponsoring entity, this short book will show you how to secure, maintain, and leverage your H-1B visa and answer all your questions about: quotas and exemptions RFEs and consular interviews dual representation by the employer’s lawyer LCA compliance, auditing, and penalties serial H-1B employers termination and benching regulations reconciling filing deadlines with expiration dates transitioning from academic to affiliated to private H-1B employment
This is a self-contained introduction to the theory of information and coding. It can be used either for self-study or as the basis for a course at either the graduate or ,undergraduate level. The text includes dozens of worked examples and several hundred problems for solution.
Ischemic heart disease is the leading cause of morbidity and mortality in the developed world. The high metabolism and oxygen demand of the cardiac myocardium depends on both a high blood flow and a rich capillary density. For this reason, the growth of the coronary vasculature is vital, not only in early development, but also in the adult faced with various stresses. Novel technologies have enabled the discovery of the molecular mechanisms underlying the growth and assembly coronary vessels, and this volume covers the hierarchy of the coronary vasculature from its embryonic origins through its postnatal growth, adulthood, and senescence. Chapters address normal coronary development, coronary anomalies and their possible underlying developmental errors, coronary vessel adaptations to exercise training, aging, hypoxia, myocardial ischemia, and cardiac hypertrophy. This comprehensive overview of current research in coronary vessels and myocardial perfusion was written by Dr. Robert J. Tomanek, Emeritus Professor of Anatomy and Cell Biology at the University of Iowa. The book reviews, discusses, and integrates findings from various areas of coronary vasculature research, and as a result, will be a valuable reference source for cardiovascular scientists and physicians for many years to come.
This classic text, one of the true anchors of our clinical genetics publishing program, covers over 700 different genetic syndromes involving the head and neck, and it has established itself as the definitive, comprehensive work on the subject. The discussion covers the phenotype spectrum, epidemiology, mode of inheritance, pathogenesis, and clinical profile of each condition, all of which is accompanied by a wealth of illustrations. The authors are recognized leaders in the field, and their vast knowledge and strong clinical judgment will help readers make sense of this complex and burgeoning field. Dr. Gorlin retires as editor in this edition and co-editor Raoul Hennekam takes over. Dr. Hennekam is regarded as one of the top dysmorphologists--and indeed one of the top clinical geneticists--in the world. Judith Allanson is new to the book but is a veteran OUP author and a widely respected geneticist, and Ian Krantz at Penn is a rising star in the field. Dr. Gorlin's name has always been closely associated with the book, and it has now become part of the title. As in all fields of genetics, there has been an explosion in the genetics of dysmorphology syndromes, and the author has undertaken a complete updating of all chapters in light of the discoveries of the Human Genome Project and other ongoing advances, with some chapters requiring complete rewriting. Additional material has been added both in terms of new syndromes and in updating information on existing syndromes. The book will appeal to clinical geneticists, pediatricians, neurologists, head and neck surgeons, otolarynologists, and dentists. The 4th edition, which published in 2001, has sold 2,600 copies.
Laser Chemistry: Spectroscopy, Dynamics and Applications provides a basic introduction to the subject, written for students and other novices. It assumes little in the way of prior knowledge, and carefully guides the reader through the important theory and concepts whilst introducing key techniques and applications.
Iron is of fundamental importance for the growth, development and well being of almost all living organisms. Multiple biological systems have been developed for the uptake, utilisation, storage and homeostasis of iron in microbes, plants and mammals. e.g. Both iron deficiency and iron overload are found extensively in man: the intimate links between iron and oxidative stress are associated with a wide range of pathologies; iron has a well established role in infections by a wide range of microorganisms and parasites; there is a close link between iron requirements and cellular division with implications for cancers and other metals such as copper and zinc are closely linked with iron metabolism. The first edition of this book was published in 1991. Since then the extensive impact of molecular cell biology on the field of iron biochemistry has opened new horizons in our understanding of the transport and storage of iron and of its homeostasis. The explosive use of molecular biological techniques applied to cellular biology of iron metabolism has resulted in a rapid expansion in the literature which has led to the need for this second edition. This second edition also: Introduces many illustrations and colour photos to make the basic concepts far clearer Includes new chapters on iron and cell division and interactions of iron with other metals - particularly copper and zinc Provides additional anecdotes Incorporates an extensive and up-to-date bibliography
This volume is the first to describe all clinically and experimental relevant aspects of primary and secondary brain stem lesions important to clinicians. It contains a detailed description of the computer-tomographical and morphological changes of the cerebral cisterns in acutely and chronically increased intracranial pressure. The prognostic value of clinical parameters of primary and secondary brain stem lesions is demonstrated. The possibilities of assessing the clinical course by computer-aided evaluation are presented. In addition to that, comprehensive view of morphological, radiological and clinical findings, extensive investigation concerning blink reflex (BR) and auditory evoked brain stem potentials (BAEP) supply highly relevant functional aspects of those lesions. The effects of raised intracranial pressure upon BR, BAEP as well as upon cerebral blood flow and focal flow in different brain areas were studied in animal experiments and reveal new and fascinating conclusions. Based on these investigations, a mathematical model following modern concepts of system analysis was developed. The model includes the intracranial system, autoregulation of cerebral flow (cardiovascular components) and the short-time behaviour of arterial blood pressure regulation.
