Download or read book Not for Circulation written by Bertha Henson and published by National University of Singapore Press. This book was released on 2022-01-22 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of George Bogaars, a civil servant who played a key role in Singapore's political history. Do civil servants make a difference? Can they shape history? In 1985 when John Drysdale published one of the first books on the political history of independent Singapore, George E. Bogaars wrote to his daughter with typical understatement, "I feature in it a bit." Bogaars headed the special branch at the time of Operation Cold Store. He reported directly to pioneer leaders such as Lee Kuan Yew and Goh Keng Swee before they became political icons. He started the Singapore Armed Forces from scratch when he was Permanent Secretary of the Interior and Defence. He was the head of the civil service, involved in a dozen or so government-linked companies attempting to shore up the country's infrastructure, and expand its business portfolio. He held the country's purse strings when he moved into the finance ministry before his retirement at the age of fifty-five. His impressive resume belies a colorful, flamboyant character with a wicked sense of humor. Veteran Singaporean journalist Bertha Henson tells his story.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.
Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Global Circulation of the Atmosphere written by Tapio Schneider and published by Princeton University Press. This book was released on 2022-12-13 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite major advances in the observation and numerical simulation of the atmosphere, basic features of the Earth's climate remain poorly understood. Integrating the available data and computational resources to improve our understanding of the global circulation of the atmosphere remains a challenge. Theory must play a critical role in meeting this challenge. This book provides an authoritative summary of the state of the art on this front. Bringing together sixteen of the field's leading experts to address those aspects of the global circulation of the atmosphere most relevant to climate, the book brings the reader up to date on the key frontiers in general circulation theory-including the nonlinear and turbulent global-scale dynamics that determine fundamental aspects of the Earth's climate. While emphasizing theory, as expressed through relatively simple mathematical models, it also draws connections to simulations with comprehensive general circulation models. Topics include the dynamics of storm tracks, interactions between wave dynamics and the hydrological cycle, monsoons, tropical and extratropical dynamics and interactions, and the processes controlling atmospheric humidity. An essential resource for graduate students in atmospheric, ocean, and climate sciences and for researchers seeking an overview of the field, The Global Circulation of the Atmosphere sets the standard for future research in a science that stands at a critical juncture. With a foreword by Edward Lorenz, the book includes chapters by Christopher Bretherton; Kerry Emanuel; Isaac Held; David Neelin; Raymond Pierrehumbert, Hélène Brogniez, and Rémy Roca; Alan Plumb; Walter Robinson; Tapio Schneider; Richard Seager and David Battisti; Adam Sobel; Kyle Swanson; and Pablo Zurita-Gotor and Richard Lindzen.

Download or read book Circulation and Control written by Marie-Stéphanie Delamaire and published by Open Book Publishers. This book was released on 2021-10-08 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nineteenth century witnessed a series of revolutions in the production and circulation of images. From lithographs and engraved reproductions of paintings to daguerreotypes, stereoscopic views, and mass-produced sculptures, works of visual art became available in a wider range of media than ever before. But the circulation and reproduction of artworks also raised new questions about the legal rights of painters, sculptors, engravers, photographers, architects, collectors, publishers, and subjects of representation (such as sitters in paintings or photographs). Copyright and patent laws tussled with informal cultural norms and business strategies as individuals and groups attempted to exert some degree of control over these visual creations. With contributions by art historians, legal scholars, historians of publishing, and specialists of painting, photography, sculpture, and graphic arts, this rich collection of essays explores the relationship between intellectual property laws and the cultural, economic, and technological factors that transformed the pictorial landscape during the nineteenth century. This book will be valuable reading for historians of art and visual culture; legal scholars who work on the history of copyright and patent law; and literary scholars and historians who work in the field of book history. It will also resonate with anyone interested in current debates about the circulation and control of images in our digital age.

Download or read book Human Heart Cosmic Heart written by Dr. Thomas Cowan and published by Chelsea Green Publishing. This book was released on 2016-10-22 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: "[This book] deserves to be in everyone’s library. . . . It’s loaded with great information, and it can save your life or the life of someone you love."—Dr. Joseph Mercola "This book is life-changing for those trying to understand their own bodies, or those of loved ones, and it’s truly transformative in the hands of medical professionals, especially young doctors."—Foreword Reviews Thomas Cowan was a 20-year-old Duke grad—bright, skeptical, and already disillusioned with industrial capitalism—when he joined the Peace Corps in the mid-1970s for a two-year tour in Swaziland. There, he encountered the work of Rudolf Steiner and Weston A. Price—two men whose ideas would fascinate and challenge him for decades to come. Both drawn to the art of healing and repelled by the way medicine was—and continues to be—practiced in the United States, Cowan returned from Swaziland, went to medical school, and established a practice in New Hampshire and, later, San Francisco. For years, as he raised his three children, suffered the setback of divorce, and struggled with a heart condition, he remained intrigued by the work of Price and Steiner and, in particular, with Steiner’s provocative claim that the heart is not a pump. Determined to practice medicine in a way that promoted healing rather than compounded ailments, Cowan dedicated himself to understanding whether Steiner’s claim could possibly be true. And if Steiner was correct, what, then, is the heart? What is its true role in the human body? In this deeply personal, rigorous, and riveting account, Dr. Cowan offers up a daring claim: Not only was Steiner correct that the heart is not a pump, but our understanding of heart disease—with its origins in the blood vessels—is completely wrong. And this gross misunderstanding, with its attendant medications and risky surgeries, is the reason heart disease remains the most common cause of death worldwide. In Human Heart, Cosmic Heart, Dr. Thomas Cowan presents a new way of understanding the body’s most central organ. He offers a new look at what it means to be human and how we can best care for ourselves—and one another.

Download or read book The Circulation of the Blood written by William Harvey and published by Cosimo, Inc.. This book was released on 2006-05-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: If the pulsations of the arteries fan and refrigerate the several parts of the body as the lungs do the heart, how comes it, as is commonly said, that the arteries carry the vital blood into the different parts, abundantly charged with vital spirits, which cherish the heat of these parts, sustain them when asleep, and recruit them when exhausted? and how should it happen that, if you tie the arteries, immediately the parts not only become torpid, and frigid, and look pale, but at length cease even to be nourished?-from the IntroductionThis seminal work of medical literature, first published in 1628, spells out in clear, lucid language how the human heart pumps blood around the body via its own exclusive circulatory route. What seems like an obvious concept to us today was in fact quite revolutionary at the time: Harvey's defiance of the medical "common knowledge" of his time laid the groundwork for all modern investigations of the circulatory system, and may be the most momentous discovery of 17th-century medicine.This important volume also includes a series of letters from Harvey to his medical colleagues in which he defends his then-astonishing theories, plus Harvey's "The Anatomy of Thomas Parr," a fascinating 1635 report on the dissection of the corpse of "a poor farmer of extremely advanced age."OF INTEREST TO: readers of scientific history, medical studentsBritish naturalist, anatomist, and doctor WILLIAM HARVEY (1578-1657) was educated at Cambridge, Canterbury, and Padua, and became a Fellow of the Royal College of Physicians in 1607. He served as court physician to both King James I and King Charles I.
