  • A Second Course in Elementary Differential Equations

    • 1st Edition
    • Paul Waltman
    • English
    A Second Course in Elementary Differential Equations deals with norms, metric spaces, completeness, inner products, and an asymptotic behavior in a natural setting for solving problems in differential equations. The book reviews linear algebra, constant coefficient case, repeated eigenvalues, and the employment of the Putzer algorithm for nondiagonalizable coefficient matrix. The text describes, in geometrical and in an intuitive approach, Liapunov stability, qualitative behavior, the phase plane concepts, polar coordinate techniques, limit cycles, the Poincaré-Bendixson theorem. The book explores, in an analytical procedure, the existence and uniqueness theorems, metric spaces, operators, contraction mapping theorem, and initial value problems. The contraction mapping theorem concerns operators that map a given metric space into itself, in which, where an element of the metric space M, an operator merely associates with it a unique element of M. The text also tackles inner products, orthogonality, bifurcation, as well as linear boundary value problems, (particularly the Sturm-Liouville problem). The book is intended for mathematics or physics students engaged in ordinary differential equations, and for biologists, engineers, economists, or chemists who need to master the prerequisites for a graduate course in mathematics.

  • NIH: An Account of Research in Its Laboratories and Clinics

    • 1st Edition
    • DeWitt Stetten
    • English
    NIH: An Account of Research in Its Laboratories and Clinics contains collected accounts of the Intramural Research Program, as they happened in the laboratories and clinics, in various installations of the National Institutes of Health across the U.S.A. One paper discusses the etiology of schizophrenia which notes that, based on evidence and expanded adoption studies by Ketty, Rosenthal, and Wender, genetic factors actually contribute to the development of the disease. In developing countries, schizophrenia follows a more benign course. Some papers describe bacteriology, mycology, viral hepatitis, basic immunology, clinical immunology, and the development of enzymology. Researchers studying proteins elucidate on the synthesis and folding of protein chains, protein conformation and dynamics, the semisynthesis and protein function, as well as on sequence analysis and collagen research. Other papers describe the breaking of the genetic code, the progress made from the genetic code to beta thalassemia, to investigations of genetic diseases (such as galactosemia, gout, Lesch-Nyhan disease, mucopolysaccharide storage disease, and sickle cell disease). One paper notes the contribution of the intramural clinical research program of the National Cancer Institute to cancer therapy with emphasis in cancer chemotherapy. Professors in pharmacology, practitioners of general medicine, specialists or researchers dealing with microchemistry, toxicology, drug therapy, or oncology will find the collection valuable.

    Methods in Immunology and Immunochemistry, Volume III: Reactions of Antibodies with Soluble Antigens provides information pertinent to antigen–antibody and hapten–antibody reactions in vitro, in free solution and in gels. This book presents the development of research in immunology and immunochemistry. Organized into three chapters, this volume begins with an overview of protein–antiprotein reactions. This text then discusses the inhibitory activity of protein fragments, which suggested that antigenic combining sites of proteins were limited regions of the whole antigen molecule. Other chapters consider the measurement of inhibitory activity, which is still the principal assay to characterize antigenic sites of proteins. This book discusses as well the immunological techniques prior to the development of gel-diffusion methods. The final chapter deals with fluorescence labeling techniques that provide powerful approaches for exploring the thermodynamic and kinetic parameters of antigen–antibody interactions. This book is a valuable resource for mathematicians and immunologists.

Organized into seven chapters, this book begins with an overview of the distinction between homology and analogy in the study of linguistic and nonlinguistic developments. This text then explains the conceptual and operational definitions for such controversial terms as intention, convention, and symbolic behavior. Other chapters consider the limits and advantages of the correlational method as applied in the research. This book discusses as well the structure and content of early symbol use, both in language and in play. The final chapter examines the processes that underlie imitation and tool use, as they contribute to the child's analysis of his culture. This book is a valuable resource for neural biologists, psychologists, and social scientists.

  • Aphids as Virus Vectors

    • 1st Edition
    • Kerry F. Harris + 1 more
    • English
    Aphids as Virus Vectors focuses on aphids as vectors of plant viruses and the fundamentals of their relationship with virus and host. The mouthparts and feeding mechanism of aphids are discussed, along with aphid penetration of plant tissues and the transmission mechanisms of aphids as virus vectors. The intrinsic properties and taxonomy of aphid-borne viruses are also examined. Comprised of 22 chapters, this book begins with an overview of the importance of aphids as vectors, their biology, and the properties of the viruses they transmit. These introductory chapters prepare the reader for later ones on aphid-virus-plant interactions. The next section deals with transmission mechanisms, with emphasis on several novel alternatives to many of the traditionally held concepts of how aphids transmit viruses. Accessory factors in non-persistent virus transmission are considered. Subsequent chapters focus on technological advances in aphid-virus research, including the use of aphid cell culturing, radioisotope methodology, membrane feeding, and electrical measurement systems. The most promising frontiers in epidemiological and control-oriented research are discussed in the last two sections. This monograph will be a useful resource for researchers from such varied sciences as entomology, plant science, and virology, as well as for graduate students taking entomology and plant pathology courses on insects in relation to plant diseases.

  • Language Use and School Performance

    • 1st Edition
    • Aaron V. Cicourel + 2 more
    • English
    Language Use and School Performance presents the results of a study undertaken during 1969-1970 to investigate the link between language use and school performance. A basic theme of this report is that early school experience is probably the most important stage in a child's educational career. The emphasis is on the acquisition and use of language at home and in the primary school. Comprised of seven chapters, this book seeks to clarify everyday school decisions made by school personnel based on the child's performances in particular classroom and testing situations that influence his/her educational career early in life. The discussion begins by focusing on the placement of students in two kindergarten classes in two southern California school districts. More specifically, the chapter examines the practices used by teachers to assign students to classes having particular characteristics; to place them in ability groups within classes; and to promote them to the next grade. Subsequent chapters explore how teachers accomplish classroom lessons; intelligence testing as a social activity; standardized tests as objective/objectifie... measures of a child's "competence" in school; and tests and experiments with children. The final chapter outlines some basic theoretical issues in the assessment of the child's performance in testing and classroom settings. This monograph will be a valuable resource for educators, sociologists, and psychologists.
