The Heart Moves In A Circular Direction

An insightful and moving account, The Heart Moves in a Circular Direction tells the story of Ingeborg Gubler Casey, nicknamed "Biby," who must come to terms with her mother's mental illness even as she battles fears that she will succumb to the same disease. While growing up, Biby shares her mother's delusional world but as a teen, conversations with her mother leave her in turmoil. After entering college, Biby tries to focus on her future. She cuts off contact with her mother, and, in her attempts to ward off guilt and anxiety, pretends she has no mother. When her older sister returns for a visit, they decide to visit their mother together. After an absence of ten years, Biby must summon all her courage to face her mother. Despite becoming a psychologist, she has little understanding of her own emotions, especially her conflicting feelings about her mother. After her father's death, as Biby re-engages with her mother, she finds herself embarked on a turbulent journey of self-discovery. She emerges more whole, and, as she begins to truly understand the depth of her legacy, she is brought closer to her mother.

The History and Philosophy of Science: A Reader brings together seminal texts from antiquity to the end of the nineteenth century and makes them accessible in one volume for the first time. With readings from Aristotle, Aquinas, Copernicus, Galileo, Descartes, Newton, Lavoisier, Linnaeus, Darwin, Faraday, and Maxwell, it analyses and discusses major classical, medieval and modern texts and figures from the natural sciences. Grouped by topic to clarify the development of methods and disciplines and the unification of theories, each section includes an introduction, suggestions for further reading and end-of-section discussion questions, allowing students to develop the skills needed to: § read, interpret, and critically engage with central problems and ideas from the history and philosophy of science § understand and evaluate scientific material found in a wide variety of professional and popular settings § appreciate the social and cultural context in which scientific ideas emerge § identify the roles that mathematics plays in scientific inquiry Featuring primary sources in all the core scientific fields - astronomy, physics, chemistry, and the life sciences - The History and Philosophy of Science: A Reader is ideal for students looking to better understand the origins of natural science and the questions asked throughout its history. By taking a thematic approach to introduce influential assumptions, methods and answers, this reader illustrates the implications of an impressive range of values and ideas across the history and philosophy of Western science.

This extensively revised second edition traces the development of the basic concepts in cardiovascular physiology in light of the accumulated experimental and clinical evidence. It considers the early embryonic circulation, where blood circulation suggests the existence of a motive force, tightly coupled to the metabolic demands of the tissues. It proposes that rather than being an organ of propulsion, the heart, serves as an organ of control, generating pressure by rhythmically impeding blood flow. New and expanded chapters cover the arterial pulse, circulation in the upright posture, microcirculation and functional heart morphology. Heart and Circulation offers a new perspective for deeper understanding of the human cardiovascular system. It is therefore a thought-provoking resource for cardiologists, cardiac surgeons and trainees interested in models of human circulation.

This outstanding resource provides a comprehensive guide to intracardiac blood flow phenomena and cardiac hemodynamics, including the developmental history, theoretical frameworks, computational fluid dynamics, and practical applications for clinical cardiology, cardiac imaging and embryology. It is not a mere compilation of the most up-to-date scientific data and relevant concepts. Rather, it is an integrated educational means to developing pluridisciplinary background, knowledge, and understanding. Such understanding allows an appreciation of the crucial, albeit heretofore generally unappreciated, importance of intracardiac blood flow phenomena in a host of multifaceted functional and morphogenetic cardiac adaptations. The book includes over 400 figures, which were prepared by the author and form a vital part of the pedagogy. It is organized in three parts. Part I, Fundamentals of Intracardiac Flows and Their Measurement, provides comprehensive background from many disciplines that are necessary for a deep and broad understanding and appreciation of intracardiac blood flow phenomena. Such indispensable background spans several chapters and covers necessary mathematics, a brief history of the evolution of ideas and methodological approaches that are relevant to cardiac fluid dynamics and imaging, a qualitative introduction to fluid dynamic stability theory, chapters on physics and fluid dynamics of unsteady blood flows and an intuitive introduction to various kinds of relevant vortical fluid motions. Part II, Visualization of Intracardiac Blood Flows: Methodologies, Frameworks and Insights, is devoted to pluridisciplinary approaches to the visualization of intracardiac blood flows. It encompasses chapters on 3-D real-time and "live 3-D" echocardiography and Doppler echocardiography, CT tomographic scanning modalities, including multidetector spiral/helical dataset acquisitions, MRI and cardiac MRA, including phase contrast velocity mapping (PCVM), etc. An entire chapter is devoted to the understanding of post processing exploration techniques and the display of tomographic data, including "slice-and-dice" 3-D techniques and cine-MRI. Part II also encompasses an intuitive introduction to CFD as it pertains to intracardiac blood flow simulations, followed--in separate chapters--by conceptually rich treatments of the computational fluid dynamics of ejection and of diastolic filling. An entire chapter is devoted to fluid dynamic epigenetic factors in cardiogenesis and pre- and postnatal cardiac remodeling, and another to clinical and basic science perspectives, and their implications for emerging research frontiers. Part III contains an Appendix presenting technical aspects of the method of predetermined boundary motion, "PBM," developed at Duke University by the author and his collaborators.

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.

Heather Webb studies medieval notions of the heart to explore the "lost circulations" of an era when individual lives and bodies were defined by their extensions into the world rather than as self-perpetuating, self-limited entities. Drawing from the works of Dante, Catherine of Siena, Boccaccio, Aquinas, and Cavalcanti and other literary, philosophic, and scientific texts, she reveals medieval answers to such fundamental questions as: Where is life located? What does it consist of? Where does it begin? And how does it end? Against the modern idea of the isolated self, the medieval heart provides a model for rethinking the body's relationship to the world it inhabits.

Truth is not something we have to seek out. It is not something that is absent and far away, requiring great effort to find. Truth is present within you as the Life that is you. In Yoga of Heart, Los Angeles-based yoga instructor Mark Whitwell takes us back to the time when yoga was first developed--to the shamanic past of the Upanishads, when yoga was practiced as a means of acknowledging, enjoying, and participating in the very source of Life. Whitwell explores the deeper tantric dimensions of hatha yoga--how yoga's purpose is to link the mind to the wonder of our own condition. He shows how hatha yoga is participation in life's polarities already in union--through the male surrender to the female principle. Yoga of Heart shows how we can forge that union of polarities within our body: above and below, front and back, left and right, male and female. Yoga of Heart focuses especially on clearing the energy centers and meridians, fostering dynamic health and allowing practitioners to create a deeper intimacy with both their partners and the energetic life forces in the universe.
