Book Description
Today's resources on bloodstain analysis are still based on methods that were derived in the 1920s. Although medical and clinical research have provided a growing body of information on blood composition and behavior, this information has been ignored in favor of historical bloodstain analysis methods-until now. With 25 years of experience in the field, author Anita Wonder shows how to use these new methods for interpreting bloodstains, including non-Newtonian fluid behavior (a process that does not conform to Sir Isaac Newton's laws of motion) and three-dimensional dispersion modeling. Blood Dynamics focuses on how to accurately identify eight bloodstain pattern types and their permutations. It covers every aspect of bloodstain analysis, and shows how some standard practices of reconstruction are not only unnecessary for identification of blood dynamics, but can even be misleading. This book presents completely new scientific evaluations of blood dynamics and will fundamentally change the way in which bloodstains are interpreted. As such, it will be required reading for anyone who deals with blood evidence at the crime scene, in the lab, or in the courtroom.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Stephen Hawking says that the 21st century will be the century of complexity and indeed now systems biology or medicine means dealing with complexity. Both the genome and physiome have emerged in studying complex physiological systems. Computational and mathematical modeling has been regarded as an efficient tool to boost the understanding about living systems in normal or pathophysiological states. Covering applied methodology, basic case studies and complex applications, this volume provides researchers with an overview of modeling and computational studies of physiology (i.e. quantitative physiology), which is becoming an increasingly important branch of systems biology. This book aims to build multi-scale models to investigate functions in living systems and explain how biomolecules, cells, organs, organ systems and organisms carry out the chemical or physical functions. Some of the models addressed are related to gene expression, calcium signalling, neural activity, blood dynamics and bone mechanics. Combining theory and practice, with extensive use of MATLAB, this book is designed to establish a paradigm for quantitative physiology by integrating biology, mathematics, physics and informatics etc. To benefit from this book, the readers are expected to have a background in general physiology and mathematics

Book Description
Praise for Hemo-Dynamics: “This book provides an elegant and intuitive derivation of the fundamental mathematics underlying fluid flow, and then applies these in a straightforward way to pulsatile blood flow in all its complexity. One of the triumphs of the book is that Zamir succeeds in making essential concepts such as the Navier-Stokes equations completely accessible to any reader with a knowledge of basic calculus. The author succeeds in conveying both the beauty of his subject matter, and his passion for the elegance and intricacies of fluid flow more generally.” Lindi Wahl, PhD, Professor of Applied Mathematics, The University of Western Ontario “Incredible, the figures alone are to die for... At first glance “Hemo-Dynamics” seems like a deep engineering and modeling dive into the mechanical properties of the cardiovascular system, blood, and how they interact to generate flow and pressure. However, the text is laid out in a stepwise manner and I was especially impressed in the way that the key conceptual figures illustrate the essential concepts. In keeping with the philosophical underpinnings of engineering, Professor Zamir has also constructed his book so that the format, text, equations and the figures are self-reinforcing. This isa book that will be of great use to those who seek to understand the cardiovascular system from a mechanical and m odeling perspective.” Michael J.

Book Description
Cardiovascular Fluid Dynamics, Volume 1 explores some problems and concepts of mammalian cardiovascular function, with emphasis on experimental studies and methods. It considers pressure measurement in experimental physiology, including the measurements of pulsatile flow, flow velocity, lengths, and dimensions; the use of control theory and systems analysis in cardiovascular dynamics; the application of computer models in cardiovascular research; the meaning and measurement of myocardial contractility; and the consequences of the steady-state analysis of arterial function. Organized into 10 chapters, this volume begins with an overview of the mammalian cardiovascular system and the essential features of cardiovascular function. It then discusses the practical problems associated with the use of pressure transducers in physiological and cardiac laboratories, the challenges involved in pulsatile flow measurement using flowmeters and thermal devices, and the mechanical analysis of the circulatory system. It explains some computer modeling techniques used in investigating the hemodynamics of the cardiovascular system, including the heart and heart muscle; basic concepts of muscle mechanics and the mechanical properties of cardiac muscle; the fluid mechanics of heart valves; and the pressure and flow in large arteries. The book concludes with a chapter on vascular resistance and vascular input impedance. This book is intended for biologists, physical scientists, and others interested in cardiovascular physiology.

Book Description
Circulatory System Dynamics reviews cardiovascular dynamics from the analytical viewpoint and indicates ways in which the accumulated knowledge can be expanded and applied to further enhance understanding of the normal mammalian circulation, to ascertain the nature of difficulties associated with disease, and to test the effect of treatment. Comprised of 10 chapters, this volume begins with an overview of the circulatory system, including its anatomy and the trigger for myocardial (heart muscle) contraction. The discussion then turns to measurement of blood pressure using invasive and non-invasive techniques; blood flow measurement, with emphasis on cardiac output and measurement in the microcirculation; the system and pulmonary arterial trees; and pulsatile pressure and flow in pulmonary veins. Subsequent chapters explore microcirculation and the anatomy of the microvasculature; the heart and coronary circulation, paying particular attention to the Frank-Starling mechanism and indices of myocardial "contractility"; and control of blood pressure, peripheral resistance, and cerebral flow. The last two chapters deal with circulatory assistance and the closed cardiovascular system. This book will be of interest to students, practitioners, and researchers in fields ranging from physiology and biology to biochemistry and biophysics.
