Cell Boundaries by Stephen H White,Gunnar von Heijne,Donald M Engelman Pdf

The central themes of Cell Boundaries concern the structural and organizational principles underlying cell membranes, and how these principles enable function. By building a biological and biophysical foundation for understanding the organization of lipids in bilayers and the folding, assembly, stability, and function of membrane proteins, the book aims to broaden the knowledge of bioscience students to include the basic physics and physical chemistry that inform us about membranes. In doing so, it is hoped that physics students will find familiar territory that will lead them to an interest in biology. Our progress toward understanding membranes and membrane proteins depends strongly upon the concerted use of both biology and physics. It is important for students to know not only what we know, but how we have come to know it, so Cell Boundaries endeavours to bring out the history behind the central discoveries, especially in the early chapters, where the foundation is laid for later chapters. Science is far more interesting if, as students, we can appreciate and share in the adventures—and misadventures—of discovering new scientific knowledge. Cell Boundaries was written with advanced undergraduates and beginning graduate students in the biological and physical sciences in mind, though this textbook will likely have appeal to researchers and other academics as well. Highlights the history of important central discoveries Early chapters lay the foundation for later chapters to build on, so knowledge is amassed High-quality line diagrams illustrate key concepts and illuminate molecular mechanisms Box features and spreads expand on topics in main text, including histories of discoveries, special techniques, and applications

Crossing the Boundaries of Life by Karl S. Matlin Pdf

A close look at Günter Blobel’s transformative contributions to molecular cell biology. The difficulty of reconciling chemical mechanisms with the functions of whole living systems has plagued biologists since the development of cell theory in the nineteenth century. As Karl S. Matlin argues in Crossing the Boundaries of Life, it is no coincidence that this longstanding knot of scientific inquiry was loosened most meaningfully by the work of a cell biologist, the Nobel laureate Günter Blobel. In 1975, using an experimental setup that did not contain any cells at all, Blobel was able to target newly made proteins to cell membrane vesicles, enabling him to theorize how proteins in the cell distribute spatially, an idea he called the signal hypothesis. Over the next twenty years, Blobel and other scientists were able to dissect this mechanism into its precise molecular details. For elaborating his signal concept into a process he termed membrane topogenesis—the idea that each protein in the cell is synthesized with an "address" that directs the protein to its correct destination within the cell—Blobel was awarded the Nobel Prize in Physiology or Medicine in 1999. Matlin argues that Blobel’s investigative strategy and its subsequent application addressed a fundamental unresolved dilemma that had bedeviled biology from its very beginning—the relationship between structure and function—allowing biology to achieve mechanistic molecular explanations of biological phenomena. Crossing the Boundaries of Life thus uses Blobel’s research and life story to shed light on the importance of cell biology for twentieth-century science, illustrating how it propelled the development of adjacent disciplines like biochemistry and molecular biology.

Degrees Of Freedom: Living In Dynamic Boundaries by Alan D M Rayner Pdf

Drawing especially on insights emerging from studies of the cellular networks formed by fungi, this book describes the fundamental indeterminacy that enables life forms to thrive in and create inconstant circumstances. It explains how indeterminacy arises from counteraction between associative and dissociative processes at the reactive interfaces between living systems and their surroundings. It stresses the relevance of these processes to understanding the dynamic contexts within which living systems of all kinds — including human societies-explore for, use up, conserve and recycle sources of energy.By focusing on dynamic boundaries, the book counterbalances the discretist view that living systems are assembled entirely from building-block-like units — individuals and genes — that can be freely sifted, as opposed to channeled, by natural selection. It also shows how the versatility that enables life forms to proliferate in rich environments, whilst minimizing losses in restrictive environments, depends on capacities for error and co-operation within a fluid, non-hierarchical power structure. Understanding this point yields a more compassionate, less competitive and less self-centred outlook on life's successes and failures.

The Nature and Behavior of Grain Boundaries by Anning Hu Pdf

In view of the dramatically increased interest in the study of grain boundaries during the past few years, the Physical Metal lurgy Committee of The Institute of Metals Division of The Metal lurgical Society, AIME, sponsored a four-session symposium on the NATURE AND BEHAVIOR OF GRAIN BOUNDARIES, at the TMS-AIME Fall Meeting in Detroit, Michigan, October 18-19, 1971. The main ob jectives of this symposium were to examine the more recent develop ments, theoretical and experimental, in our understanding of grain boundaries, and to stimulate further studies in these and related areas. This volume contains most of the papers presented at the Symposium. It is regrettable that space limitations allow the inclusion of only four of the unsolicited papers, in addition to thirteen invited papers. The papers are grouped into three sections according to their major content: STRUCTURE OF GRAIN BOUNDARIES, ENERGETICS OF GRAIN BOUNDARIES, and GRAIN BOUNDARY MOTION AND RELATED PHENOMENA. Grain boundaries, or crystal interfaces, have been of both academic and practical interest for many years. An early seminar on "Metal Interfaces" was documented in 1952 by ASM. The Fourth Metallurgical Colloquium held in France, 1960, had a broad coverage on "Properties of Grain Boundaries". More recently the Australian Institute of Metals sponsored a conference on interfaces, with the proceedings being published by Butterworths in 1969.

Geographic Objects with Indeterminate Boundaries by Peter A. Burrough,A. Frank Pdf

Current geographical information systems GIS deal almost exclusively with well-defined, static geographical objects ranging from physical landscapes to towns and transport systems. Such objects, exactly located in space, can easily be handled by modern GIS, yet form only a small proportion of all the possible geographical objects.; This book challenges the assumption that the world is compsed of exactly defined and bounded geographic objects such as land parcels, rivers and countries. ignoring the essential complexity of the world, current GIS do not adequately address problems as diverse as the resolution of crime between national boundaries, or the interpretation of views of people from different cultures. This work, bringing together a range of specialists from fields such as linguistics, computer science, land surveying, cartography and soil science, examines current research into the challenges of dealing with geographical phenomena that cannot easily be forced into one of the two current standard data models.

Mechanical Behavior of Materials by Thomas H. Courtney Pdf

This outstanding text offers a comprehensive treatment of the principles of the mechanical behavior of materials. Appropriate for senior and graduate courses, it is distinguished by its focus on the relationship between macroscopic properties, material microstructure, and fundamental concepts of bonding and crystal structure. The current, second edition retains the original editions extensive coverage of nonmetallics while increasing coverage of ceramics, composites, and polymers that have emerged as structural materials in their own right and are now competitive with metals in many applications. It contains new case studies, includes solved example problems, and incorporates real-life examples. Because of the books extraordinary breadth and depth, adequate coverage of all of the material requires two full semesters of a typical three-credit course. Since most curricula do not have the luxury of allocating this amount of time to mechanical behavior of materials, the text has been designed so that material can be culled or deleted with ease. Instructors can select topics they wish to emphasize and are able to proceed at any level they consider appropriate.

Mathematical Physiology by James Keener,James Sneyd Pdf

Divided into two volumes, the book begins with a pedagogical presentation of some of the basic theory, with chapters on biochemical reactions, diffusion, excitability, wave propagation and cellular homeostasis. The second, more extensive part discusses particular physiological systems, with chapters on calcium dynamics, bursting oscillations and secretion, cardiac cells, muscles, intercellular communication, the circulatory system, the immune system, wound healing, the respiratory system, the visual system, hormone physiology, renal physiology, digestion, the visual system and hearing. New chapters on Calcium Dynamics, Neuroendocrine Cells and Regulation of Cell Function have been included. Reviews from first edition: Keener and Sneyd's Mathematical Physiology is the first comprehensive text of its kind that deals exclusively with the interplay between mathematics and physiology. Writing a book like this is an audacious act! -Society of Mathematical Biology Keener and Sneyd's is unique in that it attempts to present one of the most important subfields of biology and medicine, physiology, in terms of mathematical "language", rather than organizing materials around mathematical methodology. -SIAM review
