        Feline Reproduction

        by Aime Johnson, Michelle Kutzler

        Cats are one of the most popular pets in the world, and as homes become smaller, and single-person households become more common, it is predicted that the numbers being bred and kept will only grow. In Feline Reproduction, the global author team cover all aspects of reproduction in the queen and the tom. Beginning with basic anatomy and normal reproduction, it goes on to cover practical knowledge about pregnancy, neonatal care, breeding soundness exams, and semen cryopreservation. It also includes an overview of factors, diseases, and abnormal conditions affecting reproduction, such as infertility, causes of abortion and contraception. Covering both pet patients and nondomestic species, this book provides a thorough grounding in feline reproduction for the general veterinary practitioner, veterinary student, animal scientist, and experienced cat breeder.

        Halogens and Noble Gases, Second Edition

        by Monica Halka, Ph.D., and Brian Nordstrom, Ed.D.

        In spite of their adjacency in the periodic table, halogens and nonmetals have very different properties. Halogens are among the most chemically reactive elements in the periodic table, exhibiting a diverse chemistry in terms of the large numbers of compounds they can form. On the other hand, noble gases are the least chemically reactive elements. In fact, before the 1960s, chemists referred to these elements as inert gases, because it was believed that they exhibited no chemistry whatsoever. Providing the basics of these elements, including their role in history and some of the important scientists involved in their discovery, this newly updated, full-color resource features up-to-date scientific understanding in a clear and accessible format. Halogens and Noble Gases, Second Edition examines the ways humans use halogens and noble gases and the resulting benefits and challenges to society, health, and the environment. Fluorine, chlorine, bromine, iodine, helium, and krypton are covered in this eBook, along with the fundamentals of chemistry and physics as well as possible future developments in halogen and noble gas science and its applications.

        Nuclear Fission Reactors, Revised Edition

        by James A. Mahaffey, Ph.D.

        Despite the many practical ways to make electrical power using nuclear reactors, the world seems to have settled on using water heated to a boil by nuclear fission as the method of choice. There are several sub-types of nuclear reactors presently being used as energy sources worldwide. Nuclear Fission Reactors, Revised Edition attempts to make sense of the technical chaos by breaking it down into small parts and explaining the purpose and function of each one. Readers are taken on a tour of a General Electric boiling water reactor plant, giving them a thorough understanding of nuclear power production. Covering such topics as air pollution, thermal pollution, the ultimate availability of uranium, fuel reprocessing, and the bottom-line cost of nuclear power, this updated, full-color resource gives a detailed analysis of nuclear fission reactors. Although nuclear reactors have more moving parts, pipe-runs, and information-gathering systems than could be imagined decades ago, this comprehensive reference makes this complicated technique understandable, filling in the thin spots in our collective knowledge.

        Reproduction in Poultry

        by Robert J Etches

        This book describes the biological basis of reproduction in poultry and places this information in the context of poultry production. The author has collated and integrated recent information from a variety of sources in order to highlight the principles of the reproductive biology of poultry. This is achieved through a well-illustrated and tabulated text which emphasizes integration rather than comprehensive literature citations. The book begins by considering the egg, proceeds to a brief description of embryonic and chick development as they relate to poultry production, and describes the physiological processes that lead to formation of the fertile egg. It concludes with a discussion of the relationship between measurements of reproductive success that are commonly used in the poultry industry and their ability to reflect the physiological processes that contribute to successful reproduction. The book is aimed at advanced undergraduates or graduate students studying animal reproduction or agriculture, as well as scientists working in the poultry industry.

        The Business of Plant Breeding is the result of a study on demand-led plant variety design for markets in Africa, sharing best practices from private and public sector breeding programmes worldwide that are applicable to improving tropical crops in Africa. Beginning with an overview of the principles of demand-led plant breeding, the book then discusses aspects such as understanding the demands of clients and markets in rural and urban areas, foresight in setting product profiles and breeding targets, and determining breeding strategy and stage plans. It also covers measuring success and making the business case for future investments in breeding programmes that will deliver new varieties to meet market demands. The book: - Brings together the experience of plant breeders around the world, representing universities, national plant breeding programmes, regional and international agricultural research institutes, and private seed companies, showcasing how to respond to changing market demands; - Provides educational resource materials within each chapter; - Includes templates for use as planning tools by plant breeding programs for determining priority traits that meet market demands. An important read for professionals and students of plant breeding and genetics, this book is also a useful resource for anyone interested in developing and disseminating new, market-led technologies to increase productivity and profitability in tropical agriculture. The study was sponsored by the Australian Centre for International Agricultural Research, the Crawford Fund and the Syngenta Foundation for Sustainable Agriculture, and managed by the University of Queensland.

        Why science denial is so dangerous and how we can protect ourselves against it

        by Holm Gero Hümmler

        The phenomenon of anti-scientific disinformation has been discussed in the recent past under the acronym FLICC (Fake experts, Logical fallacies, Impossible expectations, Cherry-picking and Conspiracy theories), especially as it pertains to the topic of climate change. What is generally missing however is a more comprehensive consideration of science denial in diff erent disciplines with a critical examination of the central arguments and a comparison of the parallels. Holm Gero Hümmler dedicates himself to this task in this readable and fact-orientated book on topics such as genetic engineering, mobile phone networks, radioactivity, and chips that are implanted under the skin for medical reasons.
