  • Neural Modeling and Neural Networks

    • 1 Edición
    • F. Ventriglia
    • Inglés
    Research in neural modeling and neural networks has escalated dramatically in the last decade, acquiring along the way terms and concepts, such as learning, memory, perception, recognition, which are the basis of neuropsychology. Nevertheless, for many, neural modeling remains controversial in its purported ability to describe brain activity. The difficulties in "modeling" are various, but arise principally in identifying those elements that are fundamental for the expression (and description) of superior neural activity. This is complicated by our incomplete knowledge of neural structures and functions, at the cellular and population levels. The first step towards enhanced appreciation of the value of neural modeling and neural networks is to be aware of what has been achieved in this multidisciplinary field of research. This book sets out to create such awareness. Leading experts develop in twelve chapters the key topics of neural structures and functions, dynamics of single neurons, oscillations in groups of neurons, randomness and chaos in neural activity, (statistical) dynamics of neural networks, learning, memory and pattern recognition.

    Protein Deposition in Animals explores the factors controlling protein deposition in farm animals including fish, poultry, and ruminants. Topics covered range from protein biosynthesis in eukaryotic cells and protein metabolism in intact animals to whole-body amino acid metabolism, synthesis of egg proteins, and metabolism of the fetus. The energy costs of protein metabolism, dietary constraints on nitrogen retention, and metabolism in muscle are also discussed. Emphasis is placed on the factors that influence protein production by animals. This book is comprised of 15 chapters; the first of which explains some fundamental aspects of protein synthesis, followed by a topic of the molecular control of protein breakdown. Two chapters then consider the measurement of whole-body protein metabolism and the integration of the metabolism of individual organs with the rest of the animal. Two 'tissues', the muscle and the fetus, are singled out for detailed analysis in subsequent chapters, while another chapter describes the synthesis of egg proteins. The factors that influence overall nitrogen retention by the animals are also examined, along with the energy costs of protein deposition, hormonal influences on protein deposition, and the use of anabolic agents to manipulate growth. Two chapters, one on poultry and the other on ruminants, are concerned with predicting rates of protein deposition. This text concludes by discussing the protein metabolism in fish. This book will be of interest to scientists working in the fields of applied biochemistry, animal nutrition and physiology, physiology, and agriculture.

    • Maxwell Knight
    • Inglés
    Pets and Their Problems, A Guide for Animal Lovers deals with the ethics and problems of pet-keeping. The author discusses the craze for unusual pets and legislation that require exotic pet owners to have a license before owning or importing animals considered in a special group. The author also examines the sources of supply and the reason why people keep pets. He then discusses housing, temperature, sanitation, feeding, and nutritional needs. The author also describes in more detail the problem of difficult feeders—those normally healthy animals that do not feed readily such as when changes in cage accommodations occur or when they are bored with the same food over time. High on the list of the author's priority is pet companion and occupation (exercise, play). Another interesting subject the author discusses is individuality, not within the species, but as a pet with its own individual characteristics. The author notes that some experienced naturalists and zoologists are skeptical about marked individual "personalities" and behavioral characteristics of animals. The author also provides some tips in caring for unusual pets such as monkeys, mongooses, and bush babies (galagos). This book can be helpful for pet owners, whether pet keeping is a hobby or a professional endeavor. It can be read by both beginning and established pet owners.

    Commentaries in Plant Science, Volume 2 is a collection of papers that reviews developments in the pure and applied science of plants. One paper discusses the role of supercooling in the winter survival mechanism of and ecological distribution of many plant communities. Another paper evaluates the Cholodny-Went theory of shoot geotropism that there is strong evidence in auxin redistribution occurring in a rapid manner to cause geotropic curvature. The magnitude of auxin redistribution is too rare to cause differential growth. Some insect pests have specific nutritional requirements and well-developed mechanisms for selecting their plant host. One paper enumerates the benefits of using insect-resistant host plant varieties, such as the non-incurrence of extra costs, these are environmentally safe, and are compatible with most other methods of pest control. Another paper discusses the nature and possible genetic manipulation of a complex bacteria, the actinomycetes, as well as its role as antibiotic producer. Another paper examines the nature of seed storage proteins and of the cellular processes that are related in their synthesis and deposition especially in cereals and legume. This collection is suitable for botanists, genecologists, taxonomists, biologists, and investigators whose works involve cell membrane research.

    The oil spill disaster that occurred when the Exxon Valdez ran aground has become part of the iconography of ecological disaster. This book synthesizes previously confidential data only recently released by the U.S. government. The data concerns the effects of this nightmarish spill on marine mammals, such as sea otters, harbor seals, killer whales, and humpback whales. Because many of the book's contributors were on site within 24 hours of this 11 million gallon catastrophe, the book is a unique longitudinal study of the demise of an ecosystem due to a single acute environmental perturbation.These certain-to-be-influe... results reported here should assist marine biologists, pathologists, toxicologists, environmentalists, engineers, and coastal planners in assessing the nature of this now legendary disaster.
