Applied Iterative Methods
1st Edition
Louis A. Hageman
English
Applied Iterative Methods discusses the practical utilization of iterative methods for solving large, sparse systems of linear algebraic equations. The book explains different general methods to present computational procedures to automatically determine favorable estimates of any iteration parameters, as well as when to stop the iterative process. The text also describes the utilization of iterative methods to solve multidimensional boundary-value problems (such as discretization stencil, mesh structure, or matrix partitioning) which affect the cost-effectiveness of iterative solution procedures. The book cites case studies involving iterative methods applications, including those concerning only three particular boundary-value problems. The text explains polynomial acceleration procedures (for example, Chebyshev acceleration and conjugate gradient acceleration) which can be applied to certain basic iterative methods or to the successive overtaxation (SOR) method. The book presents other case studies using the iterative methods to solve monoenergetic transport and nonlinear network flow multidimensional boundary-value problems. The text also describes the procedures for accelerating basic iterative methods which are not symmetrizable. The book will prove beneficial for mathematicians, students, and professor of calculus, statistics, and advanced mathematics.
Current Topics in Bioenergetics
Volume 4
1st Edition
D. Rao Sanadi
English
Current Topics in Bioenergetics, Volume 4 provides information pertinent to the molecular basis for energy transduction in membranous systems. This book presents the developments of relevant techniques in the field of bioenergetics. Organized into eight chapters, this volume begins with an overview of nonequilibrium and fluorescent probes that deal with relatively unexplored areas. This text then discusses the problem of pathways and mechanisms of energy transformations in the cell. Other chapters consider the transport of ions across the plasma membrane of nearly all living cells, which is a necessary condition for the maintenance of the vital life processes. This book discusses as well that bacterial synthesis offers basic and valuable information of general significance and remarkably stimulating challenges with direct bearing on different aspects of the problem of the basic mechanisms involved in biological electron transport-coupled energy conversion. The final chapter deals with the general models for the transport of sodium and potassium. This book is a valuable resource for biologists and biochemists.
Current Topics in Cellular Regulation
1st Edition
Volume 29
Bernard L. Horecker + 1 more
English
Current Topics in Cellular Regulation: Volume 29 is a collection of papers that deals with dynamic macromolecular interactions, ligand binding, multi-enzyme complex formation, the regulation of fatty acid uptake, and synthesis in mammary or adipose tissues. Other papers explain the functional relationships of guanosine triphosphate binding proteins, the glycogen storage disease, the regulation of the pentose phosphate pathway in the brain, as well as the regulation of carotenoid biosynthesis. One paper discusses the dissociable enzyme complexes stabilized by weak interactions, particularly on the interaction of cytosolic enzymes with the contractile apparatus, with membranes, or with functionally related enzymes. Another paper investigates the mechanism of acute regulation, in mammary epithelial cells, of the processes which collaborate to supply fatty acids for esterification to form glycerolipids (which is predominantly triacylglycerol). Glycerolipids comprise mostly the total lipid content of the secretory product of those cells—mammalian milk. The paper notes that a counter-regulatory hormone collaborating with insulin in the regulation of lipid metabolism in the lactating mammary cell, does not act via cyclic AMP. The collection can prove beneficial for biochemists, micro-biologists, bio-physicists, cellular researchers, and academicians involved in the study of cellular biology or physiology.
Current Topics in Cellular Regulation
1st Edition
Volume 23
Bernard L. Horecker + 1 more
English
Current Topics in Cellular Regulation: Volume 23 is a collection of papers that discusses pyruvate carboxylase, the regulation of carbohydrate metabolism, and the plasma membrane ATPase of fungi or plants. Other papers deal with adrenergic control of phosphofructokinase, protein phosphatase, as well as the regulation of polypeptide precursors of mature mitochondrial proteins. One paper explains the three dimensional structure of pyruvate carboxylase and its reaction mechanism. Electron microscopic analyses show that four monomers of pyruvate carboxylases isolated from vertebrate sources form a tight tetrahedron-like structure. Another paper describes the regulation of fructose 2,6-bisphosphate concentration in the liver and of the enzymes that are responsible for its metabolism, and the mechanism involved in fructose, particularly in the regulation of 6-phosphofructo-1-ki... and fructose-1,6-bisphos... activity. The paper also explains the role of this effector in the regulation of hepatic carbohydrate metabolism. One paper deals with the different levels of biological organization (whole cells, isolated plasma membranes, and purified enzyme) that characterizes the plasma membrane ATPase of fungi and plants as a novel type of proton pump. The collection can prove useful for biologists, microbiologists, students, and professors of biology and biophysics.
Gene Activity in Early Development
1st Edition
Eric H. Davidson
English
Gene Activity in Early Development reviews the state of knowledge regarding genomic function in the programming and operation of what Bonnet, in 1762, described as "the miracle of epigenesis." The book is divided into four sections. Section I is concerned with gene activity in early embryogenesis, with the time of onset and the nature of embryo genome control, and with recent attempts to analyze the shifting patterns of gene expression as development proceeds. Section II reviews various classic and recent studies relevant to the phenomenon of cytoplasmic localization of morphogenetic potential and discusses the significance, from a contemporary vantage point, of this often neglected area of developmental biology. Section III deals with genomic function in oogenesis, beginning with a general survey of what could be described loosely as the natural history of the oocyte nucleus, and proceeding to current attempts to understand the character and the ultimate function of the oocyte gene products. Section IV discusses various aspects of the general problem of gene regulation in animal cells.
Advances in Steroid Biochemistry and Pharmacology
1st Edition
M. H. Briggs + 1 more
English
Advances in Steroid Biochemistry and Pharmacology, Volume 4 provides information pertinent to the fundamental aspects of steroid biochemistry and pharmacology. This book covers a variety of topics, including cellular biochemistry, pituitary hormones, corticosteroids, and steroid hormones. Organized into seven chapters, this volume begins with an overview of the potential effects of steroids on cellular biochemistry. This text then examines the development of sleep-monitoring methods, together with methods of plasma sampling that enable very frequent specimen to be taken without disturbing the subject. Other chapters consider the usefulness of sleep-related growth hormone release in diagnosis in both children and adult. This book discusses as well the versatile effect of corticosteroids on the cellular components of the connective tissue. The final chapter deals with the functioning of the adrenal cortex and its control by adrenocorticotropic hormone (ACTH). This book is a valuable resource for biochemists, histochemists, biologists, pharmacologists, clinicians, and experimental endocrinologists.
Clinical Immunobiology
1st Edition
Volume 2
Fritz H. Bach + 1 more
English
Clinical Immunobiology, Volume 2 covers the advances in the field being made to apply bone marrow transplantation to the treatment of several diseases. This volume is divided into 11 chapters and begins with surveys of the clinical considerations of bone marrow transplantation. Considerable chapters are devoted to the application of this transplantation to the treatment of various diseases, including aplastic anemia, aregenerative pancytopenia, leukemia, uniformly fatal severe combined immunodeficiency diseases, and Wiskott-Aldrich syndrome. Other chapters examine the cellular engineering in the form of bone marrow and thymus transplantation. The remaining chapters consider the effects of exposure to excessive amounts of radiation or cytotoxic chemicals, as well as the hematopoietic failure based on malfunction of the complex process of normal hematological development and maintenance. This book will be of great value to clinical immunobiologists, practicing physicians, researchers, and medical and biology students.
Speech and Language
Advances in Basic Research and Practice
1st Edition
Volume 2
Norman J. Lass
English
Speech and Language: Volume 2, Advances in Basic Research and Practice is a compendium of papers that discusses the processes and pathologies of speech and language, such as functional articulation disorders, lexical development, and a group therapy for treating stuttering. Some papers deal with vocal fold vibrations, childhood homonymy, framework for conversational speech behaviors, and vibrotactile testing. One paper cites studies of Hersen and Barlow (1976) that treatments warrant consideration only if these are powerful enough to effect obvious gains; and of Gilbert, McPeek, and Mosteller (1977) that treatment research is more likely to give modest than substantial gains—the degree of gains which can also be difficult to detect. Another paper examines suggestions for teaching words to language-disordered children, that when knowledge of normal language processes is applied in training approaches, effective and individualized programs will follow. Used in the treatment of stuttering, the Shaping Group, which employs action and many other treatment models, shows that its approach is effective. Another paper notes that before a surgical correction of voice disorders is undertaken, the importance of knowing the possible effects of various procedures on the voice should first be known. The compendium is well suited for linguists, ethnologists, psychologists, speech therapists, and researchers whose works involve linguistics, learning, communications, corrective surgery, and syntax.
Introduction to Structural Equation Models
1st Edition
Otis Dudley Duncan
English
Introduction to Structural Equation Models prepares the reader to understand the recent sociological literature on the use of structural equation models in research, and discusses methodological questions pertaining to such models. The material in first seven chapters is almost entirely standard, with the remaining four introducing progressively more open-ended issues, seducing the reader into beginning to think for himself about the properties of models or even to suggest problems that may intrigue the advanced student.

Volume 2
1st Edition
Volume 2
W. K. Hayman
P. M. Cohn + 1 more
English
Building on the foundation laid in the first volume of Subharmonic Functions, which has become a classic, this second volume deals extensively with applications to functions of a complex variable. The material also has applications in differential equations and differential equations and differential geometry. It reflects the increasingly important role that subharmonic functions play in these areas of mathematics. The presentation goes back to the pioneering work of Ahlfors, Heins, and Kjellberg, leading to and including the more recent results of Baernstein, Weitsman, and many others. The volume also includes some previously unpublished material. It addresses mathematicians from graduate students to researchers in the field and will also appeal to physicists and electrical engineers who use these tools in their research work. The extensive preface and introductions to each chapter give readers an overview. A series of examples helps readers test their understatnding of the theory and the master the applications.
