Download or read book Life at High Pressure written by Alister Macdonald and published by Springer Nature. This book was released on 2021-07-12 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses the ways in which high hydrostatic pressure (i.e. water pressure) affects all grades of life which thrive at pressures much greater those in our normal environment. The deep sea is the best known high pressure environment, where pressures reach a thousand times greater than those at the surface, yet it is populated by a variety of animals and microorganisms. The earth’s crust supports microorganisms which live in water filled pores at high pressure. In addition, the load bearing joints of animals like ourselves experience pulses of hydrostatic pressure of a magnitude similar to the pressure at mid ocean depths. These pressures affect molecular structures and biochemical reactions. Basic cellular processes are drastically affected – the growth and division of cells, the way nerves conduct impulses and the chemical reactions which provide energy. Adaptation to high pressure also occurs in complex physiological systems such as those which provide buoyancy. Probably the greatest challenge to our understanding of adaptation to high pressure is the stabilisation of the nervous system of deep sea animals to avoid convulsions which pressure causes in shallow water animals. Additionally the book provides insight into the engineering required to study life at high pressure: equipment which can trap small deep sea animals and retrieve them at their high pressure, equivalent equipment for microorganisms, laboratory microscopes which can focus on living cells under high pressure, incubators for bacteria which require high pressure to grow, high pressure aquaria for marine animals and lastly and briefly, manned and unmanned submersible vessels, Landers and deep drill hole sampling. Rather like the organisms studied many laboratory instruments have been adapted to function at high pressure.

Download or read book The Hadal Zone written by Alan Jamieson and published by Cambridge University Press. This book was released on 2015-01-29 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hadal zone represents one of the last great frontiers in marine science, accounting for 45% of the total ocean depth range. Despite very little research effort since the 1950s, the last ten years has seen a renaissance in hadal exploration, almost certainly as a result of technological advances that have made this otherwise largely inaccessible frontier, a viable subject for research. Providing an overview of the geology involved in trench formation, the hydrography and food supply, this book details all that is currently known about organisms at hadal depths and linkages to the better known abyssal and bathyal depths. New insights on how, where and what really survives and thrives in the deepest biozone are provided, allowing this region to be considered when dealing with sustainability and conservation issues in the marine environment.

Available in PDF, EPUB and Kindle. Book excerpt: Nobody performs better under pressure. Regardless of the task, pressure ruthlessly diminishes our judgment, decision-making, attention, dexterity, and performance in every professional and personal arena. In Performing Under Pressure, Drs. Hendrie Weisinger and J.P. Pawliw-Fry introduce us to the concept of pressure management, offering empirically tested short term and long term solutions to help us overcome the debilitating effects of pressure. Performing Under Pressure tackles the greatest obstacle to personal success, whether in a sales presentation, at home, on the golf course, interviewing for a job, or performing onstage at Carnegie Hall. Despite sports mythology, no one "rises to the occasion" under pressure and does better than they do in practice. The reality is pressure makes us do worse, and sometimes leads us to fail utterly. But there are things we can do to diminish its effects on our performance. Performing Under Pressure draws on research from over 12,000 people, and features the latest research from neuroscience and from the frontline experiences of Fortune 500 employees and managers, Navy SEALS, Olympic and other elite athletes, and others. It offers 22 specific strategies each of us can use to reduce pressure in our personal and professional lives and allow us to better excel in whatever we do. Whether you’re a corporate manager, a basketball player, or a student preparing for the SAT, Performing Under Pressure will help you to do your best when it matters most.
Download or read book The Power of Pressure written by Dane Jensen and published by HarperCollins. This book was released on 2021-08-31 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Be energized, but not overwhelmed What’s the most pressure you’ve ever been under? How did you react? What helped? What didn’t? Over the past five years, Dane Jensen has asked these questions of thousands of high performers—from Olympic gold medalists to Navy SEALs, politicians, executives and busy parents. What has emerged from these conversations is that while everyone’s experiences under pressure are unique, pressure follows patterns and develops in predictable ways. If we can recognize the patterns, we can improve our ability to sidestep the biological traps that can sabotage us—and use the energy that accompanies pressure to thrive. The Power of Pressure combines the insights gathered from Jensen’s work with the latest research in biology and neuroscience to help you understand and use the “pressure equation” of importance, uncertainty and volume escape the traps of pressure with effective tools and tactics be ambidextrous so that you can handle pressure both in peak pressure moments and over the long haul reduce tension, sleep better and have more energy so that you can meet challenges head-on recognize pressure moments so that you can prepare for when you will likely the feel the heat leverage strategies so that you can give everything you’ve got when it’s most important And more! How we navigate our highest-pressure moments has a huge impact on the overall trajectory of our lives, both in terms of how successful we are and how much we enjoy the journey along the way.
Download or read book High Pressure Processing of Fruit and Vegetable Products written by Milan Houška and published by CRC Press. This book was released on 2017-10-24 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: High pressure processing is a fast-growing food processing technology and opens the door to nearly-fresh products that retain their sensorial and nutritional qualities. High Pressure Processing of Fruit and Vegetable Products reviews and summarizes the latest advances in novel high-pressure processing techniques for preserving fruits, fruit juices, and their mixtures. It contains basic information on the relation of high-process treatment parameters with the safety and quality of fruit and vegetable juices/products. The book focuses on product quality parameters, nutritional value, bio-active health components, and microbial safety and stability. The main aim of this book is to summarize the advances in the utilization of modern high pressure pasteurization (HPP) treatment to preserve and stabilize fruit and vegetable products. HPP technology is related to the product quality parameters, the content of nutritional and health active components, and the microbial safety and subsequent shelf life. One chapter of this book is devoted to industrial equipment available; other chapters deal with examples of commercial fruit and vegetable products. Another chapter of this book is dedicated to packaging, as packaging of food before HPP is mandatory in this technology. The regulatory aspects for high-pressure treated fruit and vegetable products in different regions of the world (Europe, the United States, Asia, and Australia) are also an important topic dealt within one chapter of the book. The effects of HPP technology on the quality of fruit and vegetable products, namely nutrients and stability, health active components, and sensory aspects, are reviewed in a trio of chapters.
Download or read book Recent Developments in High Pressure Processing of Foods written by Navin K Rastogi and published by Springer Science & Business Media. This book was released on 2013-07-16 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features a Foreword by Dr. Dietrich Knorr. Fruit processing and preservation technologies must ensure fresh-like characteristics in foods while providing an acceptable and convenient shelf life, as well as assuring safety and nutritional value. Processing technologies include a wide range of methodologies to inactivate microorganisms, improve quality and stability, and preserve and minimize changes of fresh-like characteristics in fruit. High pressure as a food preservation technique inactivates microorganisms at room temperature or lower; thus, sensory and nutritional characteristics can be maintained. In recent years, a significant increase in the number of scientific papers in literature demonstrating novel and diversified uses of high pressure processing indicates it to be highly emerging technology. The effect of high pressure technology on the quality and safety of foods will be discussed. Selected practical examples in fruits and vegetables, dairy and meat industries using high pressure will be presented and discussed. A brief account of the challenges in adopting this technology for industrial development will also be included.

Download or read book Pressed for Time written by Judy Wajcman and published by University of Chicago Press. This book was released on 2015 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technologically tethered, iPhone-addicted figure is an image we can easily conjure. Most of us complain that there aren't enough hours in the day and too many e-mails in our thumb-accessible inboxes. This widespread perception that life is faster than it used to be is now ingrained in our culture, and smartphones and the Internet are continually being blamed. But isn't the sole purpose of the smartphone to give us such quick access to people and information that we'll be free to do other things? Isn't technology supposed to make our lives easier? In Pressed for Time, Judy Wajcman explains why we immediately interpret our experiences with digital technology as inexorably accelerating everyday life. She argues that we are not mere hostages to communication devices, and the sense of always being rushed is the result of the priorities and parameters we ourselves set rather than the machines that help us set them. Indeed, being busy and having action-packed lives has become valorized by our productivity driven culture. Wajcman offers a bracing historical perspective, exploring the commodification of clock time, and how the speed of the industrial age became identified with progress. She also delves into the ways time-use differs for diverse groups in modern societies, showing how changes in work patterns, family arrangements, and parenting all affect time stress. Bringing together empirical research on time use and theoretical debates about dramatic digital developments, this accessible and engaging book will leave readers better versed in how to use technology to navigate life's fast lane.

Download or read book The High Blood Pressure Solution written by Richard D. Moore and published by Simon and Schuster. This book was released on 2001-05-01 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Proves that the majority of cases of stroke, heart attack, and hypertension can easily be prevented by maintaining the proper ratio of potassium to sodium in the diet. • Updated with scientific evidence from a recent Finnish study showing a 60 percent decline in deaths attributed to strokes and heart attacks. • Provides a comprehensive program for balancing body chemistry at the cellular level. High blood pressure is entirely preventable, without reliance on synthetic drugs. Dr. Moore's approach is simple: by maintaining the proper ratio of potassium to sodium in the diet, blood pressure can be regulated at the cellular level, preventing the development of hypertension and the high incidence of strokes and heart attacks associated with it. Dr. Moore updates this edition with a new preface reporting on the latest scientific research in support of his program. The most striking results come from Finland, where for several decades sodium chloride has been replaced nationwide with a commercial sodium/potassium mixture, resulting in a 60 percent decline nationwide in deaths attributed to strokes and heart attacks. Extrapolated to America, the Finnish statistics would mean 360,000 strokes prevented and 96,000 lives saved every year. Dr. Moore makes it clear that high blood pressure is only one symptom of an entire systemic imbalance. He outlines a safe, effective program that focuses on nutrition, weight loss, and exercise to bring the entire body chemistry into balance. For those currently taking blood pressure medications, he includes a chapter on working with your physician to ensure that any reduction in hypertension drugs can be effected gradually and safely.
Download or read book Deep Subsurface Microbiology written by Andreas Teske and published by Frontiers Media SA. This book was released on 2015-07-01 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep subsurface microbiology is a highly active and rapidly advancing research field at the interface of microbiology and the geosciences; it focuses on the detection, identification, quantification, cultivation and activity measurements of bacteria, archaea and eukaryotes that permeate the subsurface biosphere of deep marine sediments and the basaltic ocean and continental crust. The deep subsurface biosphere abounds with uncultured, only recently discovered and – at best - incompletely understood microbial populations. In spatial extent and volume, Earth's subsurface biosphere is only rivaled by the deep sea water column. So far, no deep subsurface sediment has been found that is entirely devoid of microbial life; microbial cells and DNA remain detectable at sediment depths of more than 1 km; microbial life permeates deeply buried hydrocarbon reservoirs, and is also found several kilometers down in continental crust aquifers. Severe energy limitation, either as electron acceptor or donor shortage, and scarcity of microbially degradable organic carbon sources are among the evolutionary pressures that have shaped the genomic and physiological repertoire of the deep subsurface biosphere. Its biogeochemical role as long-term organic carbon repository, inorganic electron and energy source, and subduction recycling engine continues to be explored by current research at the interface of microbiology, geochemistry and biosphere/geosphere evolution. This Research Topic addresses some of the central research questions about deep subsurface microbiology and biogeochemistry: phylogenetic and physiological microbial diversity in the deep subsurface; microbial activity and survival strategies in severely energy-limited subsurface habitats; microbial activity as reflected in process rates and gene expression patterns; biogeographic isolation and connectivity in deep subsurface microbial communities; the ecological standing of subsurface biospheres in comparison to the surface biosphere – an independently flourishing biosphere, or mere survivors that tolerate burial (along with organic carbon compounds), or a combination of both? Advancing these questions on Earth’s deep subsurface biosphere redefines the habitat range, environmental tolerance, activity and diversity of microbial life.
Download or read book Stress and Hypertension written by Kevin T. Larkin and published by Yale University Press. This book was released on 2008-10-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does living a stress-filled life lead to elevated blood pressure? And if so, do strategies to better manage stress effectively lower blood pressure? In this authoritative and comprehensive book, Kevin T. Larkin examines more than a half-century of empirical evidence obtained to test the common assumption that stress is associated with the onset and maintenance of essential hypertension (high blood pressure). While the research confirms that stress does play a role in the exacerbation of essential hypertension, numerous other factors must also be considered, among them obesity, exercise, and smoking, as well as demographic, constitutional, and psychological concerns. The author discusses the effectiveness of strategies developed to manage stress and thereby lower blood pressure and concludes with suggestions and directions for further study.
