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
Bloodstain Patterns: Identification, Interpretation and Application combines material from Blood Dynamics (2001) and Bloodstain Pattern Evidence (2007) with updated case work and scientific advances from medical and hard sciences. The text expands coverage of such areas as arterial damage pattern identification, staging of crime scenes, legal applications and problems from both sides of the bench, and extending teaching and training to those outside criminal justice. With violent offenders more aware of crime scene investigation techniques and attempting to frame others, the text expands outdated basic training programs that are insufficient to identify attempts to confuse the investigation. This book clarifies previous understandings as well as bridges the gap toward future advance courses. Based on the work of Paul Leland Kirk, the book's focus is on first line investigators' accuracy in identifying specific bloodstain patterns, correctly interpreting and applying them to casework. - Combines and updates material from Blood Dynamics and Bloodstain Pattern Evidence into one comprehensive reference - Covers new topics, including arterial damage pattern identification, staging of crime scenes, legal applications, and problems from both sides of the bench - More than 300 full color photographs, some with line overlays showing the objective criteria which identify patterns

Book Description
This thesis is divided into two parts, each of which examines aspects of bloodstain analysis where gravity is the main force applied to blood. Part I is a preliminary study on the dynamics of blood flow on various inclined surfaces and examines the use of blood analogs for easy test replication. The flow of uncoagulated human blood at different volumes and temperatures was examined on wood at a set angle of 1.5°, and on glass at varying incline angles. Glycerol solutions of 59% and 42% were used to represent blood at 23°C and 37°C respectively. Glycerol flow trials of similar volumes were conducted on wood, PVC and glass. Fluid flow plots of distance versus time exhibited double exponential curve behaviour, although a power-law relationship derived by H. E. Huppert's (1982) flow expression was obtained for blood flowing on inclined wood. Blood flow exhibited several observable characteristics; a decreasing width of the leading edge over time, and streaking and component separation of the leading region at very low speeds. On a glass surface, the width of the initial flow region decreased and initial speed increased with increasing angles. The glycerol analogs used in this study did not represent their blood counterparts well due to differences in physical properties of the fluids. Part II of this study focuses on the forensic value of passive bloodstains on three fabrics; 100% cotton drill, 65/35 polyester cotton, and 100% Shantung silk. 26 oL drops of 37°C human blood were deposited onto the three fabrics and paper from a height of 14 cm at various impact angles. The stains were photographed and analysed qualitatively and quantitatively using computational methods. 100% cotton drill, 65/35 polyester cotton and ironed 100% Shantung silk provided useful forensic values such as direction of travel and angle of impact. Overall, this study has provided useful preliminary data for further research work.

Book Description
Blood microcirculation is essential to our bodies for the successful supply of nutrients, waste removal, oxygen delivery, homeostasis, controlling temperature, wound healing, and active immune surveillance. This book provides a physical introduction to the subject and explores how researchers can successfully describe, understand, and predict behaviours of blood flow and blood cells that are directly linked to these important physiological functions. Using practical examples, this book explains how the key concepts of physics are related to blood microcirculation and underlie the dynamic behavior of red blood cells, leukocytes, and platelets. This interdisciplinary book will be a valuable reference for researchers and graduate students in biomechanics, fluid mechanics, biomedical engineering, biological physics, and medicine. Features: The first book to provide a physical perspective of blood microcirculation Draws attention to the potential of this physical approach for novel applications in medicine Edited by specialists in this field, with chapter contributions from subject area specialists

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.

Book Description
In Bloodstain Pattern Evidence, the concepts introduced in the author's first book, Blood Dynamics, are updated and applied to provide essential answers in the resolution of actual crimes. The book is accessible to all levels of investigators, regardless of academic background, and allows readers to develop a fundamental understanding of the underlying scientific principles behind bloodstain pattern evidence. Bloodstain Pattern Evidence builds on the fundamental ideas brought about by an understanding of Non-Newtonian dynamics, and illustrates through case work the practical forensic science applications of these principles to the analysis of bloodstain patterns. - Extensive case examples provide practical application of essential pattern analysis principles - Extensively illustrated with over 350 photos and line drawings - Takes a unique and scientific approach to bloodstain pattern analysis by exploring the fundamentals of fluid behavior
