This book was released on 2021-08-24 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrons are involved in all electrical phenomena, and living cells cannot be an exception. This book takes on a decidedly different approach to existing texts on electrophysiology, by considering electrical physiological processes from the viewpoint of electron flow, rather than the conventional notion of ion movement. It concisely describes the theoretical background of electron density and cellular voltage, before exploring thought-provoking questions such as the relationship between electrolyte distribution and transmembrane potential, and the source of electricity generation in living cells. A new electromagnetic theory of muscular function is presented, and all topics of relevance — including the electrophysiology of invertebrates, plants, fungi and bacteria — are comprehensively covered. Using plain language and more than 40 original illustrations, the author has designed each chapter to provide a succinct overview of an individual topic in a format that appeals to both the expert and the uninitiated. Electromagnetism, Quanta, and Electron Flow in the Electrophysiology of Living Cells proffers a refreshingly new way to understand a fascinatingly old subject.

Download or read book Conversations on Cardiac Physiology written by Mark Noble and published by Cambridge Scholars Publishing. This book was released on 2023-12-08 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses and corrects widespread misconceptions regarding heart physiology. Such misconceptions include: the voltage in cells is attributed to potassium ion concentration differences between the extracellular and intracellular compartments, which are the same in all organs of the body, whereas the voltage in cells of these same organs vary widely. This book argues that depolarisation and repolarisation can be explained by electron outflow and mitochondrial production, respectively; and that the trigger for internal calcium ion release is calcium ions bound to the inner leaflet of the cell membrane. In the book, Starling’s Law is contrasted with contractility increase, and it is posited that hypertension is not caused by salty diet, coronary artery disease risk is not correlated with total cholesterol (rather, only with some specific cholesterols), and that drug administration should be titrated.

Download or read book Starling s Law of The Heart Revisited written by Henk Keurs and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. E. D. J. TER KEURS & M. I. M. NOBLE The "Starling's Law of the Heart" and "The Frank-Starling Mechanism" have long been the cornerstone of cardiac mechanical physiology. It is often forgotten that Frank and Starling carried out fundamentally different exper iments. Frankl measured the isovolumic pressure developed by frog heart at different volumes. He therefore discovered the pressure-volume-volume rela tionship which depends directly on the force-length relationship of the 2 sarcomeres. Starling ,3 studied cardiac shortening as manifest by cardiac output and its relationship to end-diastolic conditions as manifest by right atrial pressure. Thus he was studying the ability of cardiac muscle to shorten more at a given load from a greater initial length. Starling in the promulga 4 tions of his law implied a common mechanism for these two phenomena and spoke of the "energy liberated" being a function of initial muscle fiber length. However, there has been much confusion about the interrelationship between the two different aspects studied by Frank and Starling. The 1960s saw the era of isolated cardiac muscle mechanics, beginning with 5 the paper of Abbott and Mommaerts. Whole muscle length-tension relations were equated with sarcomere-length-tension relations by fixation of muscle at a particular point on the curve and determination of sarcomere length by electronmicroscopy.
Download or read book QED Coherence in Matter written by Giuliano Preparata and published by World Scientific. This book was released on 1995 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up until now the dominant view of condensed matter physics has been that of an ?electrostatic MECCANO? (erector set, for Americans). This book is the first systematic attempt to consider the full quantum-electrodynamical interaction (QED), thus greatly enriching the possible dynamical mechanisms that operate in the construction of the wonderful variety of condensed matter systems, including life itself.A new paradigm is emerging, replacing the ?electrostatic MECCANO? with an ?electrodynamic NETWORK,? which builds condensed matter through the long range (as opposed to the ?short range? nature of the usual electrostatic forces) electrodynamical interaction; this interaction creates ?coherent configurations? of the elementary systems (atoms and molecules), which oscillate in phase with a coherent macroscopic (and classical) electromagnetic field that, through the strong interaction with matter, remains trapped inside it.
Download or read book Matter and Mind written by Mario Bunge and published by Springer Science & Business Media. This book was released on 2010-09-14 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses two of the oldest and hardest problems in both science and philosophy: What is matter?, and What is mind? A reason for tackling both problems in a single book is that two of the most influential views in modern philosophy are that the universe is mental (idealism), and that the everything real is material (materialism). Most of the thinkers who espouse a materialist view of mind have obsolete ideas about matter, whereas those who claim that science supports idealism have not explained how the universe could have existed before humans emerged. Besides, both groups tend to ignore the other levels of existence—chemical, biological, social, and technological. If such levels and the concomitant emergence processes are ignored, the physicalism/spiritualism dilemma remains unsolved, whereas if they are included, the alleged mysteries are shown to be problems that science is treating successfully.
Download or read book Biophysics written by William Bialek and published by Princeton University Press. This book was released on 2012-12-17 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: A physicist's guide to the phenomena of life Interactions between the fields of physics and biology reach back over a century, and some of the most significant developments in biology—from the discovery of DNA's structure to imaging of the human brain—have involved collaboration across this disciplinary boundary. For a new generation of physicists, the phenomena of life pose exciting challenges to physics itself, and biophysics has emerged as an important subfield of this discipline. Here, William Bialek provides the first graduate-level introduction to biophysics aimed at physics students. Bialek begins by exploring how photon counting in vision offers important lessons about the opportunities for quantitative, physics-style experiments on diverse biological phenomena. He draws from these lessons three general physical principles—the importance of noise, the need to understand the extraordinary performance of living systems without appealing to finely tuned parameters, and the critical role of the representation and flow of information in the business of life. Bialek then applies these principles to a broad range of phenomena, including the control of gene expression, perception and memory, protein folding, the mechanics of the inner ear, the dynamics of biochemical reactions, and pattern formation in developing embryos. Featuring numerous problems and exercises throughout, Biophysics emphasizes the unifying power of abstract physical principles to motivate new and novel experiments on biological systems. Covers a range of biological phenomena from the physicist's perspective Features 200 problems Draws on statistical mechanics, quantum mechanics, and related mathematical concepts Includes an annotated bibliography and detailed appendixes

Download or read book Color for Science Art and Technology written by Kurt Nassau and published by Elsevier. This book was released on 1997-12-18 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to assemble a series of chapters, written by experts in their fields, covering the basics of color - and then some more. In this way, readers are supplied with almost anything they want to know about color outside their own area of expertise. Thus, the color measurement expert, as well as the general reader, can find here information on the perception, causes, and uses of color. For the artist there are details on the causes, measurement, perception, and reproduction of color. Within each chapter, authors were requested to indicate directions of future efforts, where applicable. One might reasonably expect that all would have been learned about color in the more than three hundred years since Newton established the fundamentals of color science. This is not true because:• the measurement of color still has unresolved complexities (Chapter 2)• many of the fine details of color vision remain unknown (Chapter 3)• every few decades a new movement in art discovers original ways to use new pigments, and dyes continue to be discovered (Chapter 5)• the philosophical approach to color has not yet crystallized (Chapter 7)• new pigments and dyes continue to be discovered (Chapters 10 and 11)• the study of the biological and therapeutic effects of color is still in its infancy (Chapter 2).Color continues to develop towards maturity and the editor believes that there is much common ground between the sciences and the arts and that color is a major connecting bridge.

Download or read book Time And Beauty Why Time Flies And Beauty Never Dies written by Adrian Bejan and published by World Scientific. This book was released on 2022-02-15 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time and beauty are two of our most visceral perceptions. Yet, their nature is seldom questioned. In this ground-breaking new work, Adrian Bejan — a true 'original' among physicists — explains, in a scholarly yet colorful style, the scientific basis for the perception of time and beauty.Organized into three main ideas, the book begins first with the perception of time. The author expounds on why we feel that time flies faster as we get older. Perceived time, also called 'mind time,' is different from clock time. In this context, time is another word for 'perceived change'. Next, readers will discover that beauty is appealing because beautifully-shaped images are scanned faster by two eyes. To observe our immediate surroundings and to understand them faster is highly advantageous to survival; hence, there is an underlying evolutionary advantage to our discernment for ideal ratios, shapes, and beauty at large. Finally, time and beauty are jointly understood to explain why the global pandemic had decelerated our mind time. This understanding arms us with techniques to slow down our mind time (which accelerates with age), and to create the conditions for living longer and more creatively.Scientists may have contemplated aspects of time and beauty separately. In contrast, the author submits an original and rewarding approach to understanding them together. In the process, key questions to our cognition are answered. Why does the mind 'try' to make sense of a new mental image? Why is there a natural tendency to organize a new input and mentally position it among past perceptions? Through physics, the book offers a general answer: to empower the individual with speed and clarity of thought, understanding, decision-making and movement. The same answer holds for the other disparate perceptions illustrated in this book, from time and beauty to ideas, message, shape, perspective, art, science, illusions, and dreams.
