Oxygen Diving (Diving Sciences)
Par Ryszard Klos. 2023
The book provides a derivation of the models used for calculating the risk and hazard of central oxygen toxicity pertaining…
to diving-based studies consistent with the research conducted earlier by the Royal Navy and the US Navy. This book forms the basis for extending the possibility of undertaking nitrox dives in combination with oxygen dives, thus significantly increasing tactical capabilities of conducting diving special operations. Features: provides derivation of the models used for calculating the risk and hazard of central oxygen toxicity improves oxygen diving procedures described in the US Navy Diving Manual includes procedures applicable to undertaking nitrox dives in combination with oxygen dives pitches the material at highest technology readiness levels, i.e. 9 TRL aims to increase tactical capabilities of conducting diving special operations This book is aimed at researchers, professionals and graduate students in life support system design, diving submarine safety, ventilation, health, sanitary engineering, mining engineering and working environment in chambers or closed compartments.The Electronic Transitions of Molecular Oxygen
Par Mikkel Bregnh j. 2019
This book presents the fundamentals and the state of the art of the photophysics of molecular oxygen. The author examines…
optical transitions between the lowest-lying electronic states in molecular oxygen and how these transitions respond to perturbation, either from an organic molecule or from the plasmon field of a metal nanoparticle. We live on a planet filled with light and oxygen. The interaction between these two components forms the basis of excited state chemistry spanning the fields of synthetic organic chemistry, materials chemistry, molecular biology, and photodynamic treatment of cancer. Still, the fundamental ways in which oxygen is affected by light is an active subject of research and is continually being developed and rationalized. In this book, readers will learn that singlet oxygen, the excited state of oxygen that exhibits unique chemical reactivity, can be selectively made via direct optical excitation of oxygen in a sensitizer-free system. Readers will also discover that this approach can perturb living cells differently depending on the singlet oxygen “dose”.Oxygen: The Molecule That Made the World
Par Nick Lane. 2003
Nick Lane shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the evolution of animals, the…
need for two sexes, the aging of cloned animals like Dolly the sheep, and the surprisingly long lives of birds.The Future of Atmospheric Oxygen (SpringerBriefs in Environmental Science)
Par V. N. Livina, T. M. Vaz Martins. 2020
This book investigates various aspects of the phenomenon of atmospheric oxygen depletion, and summarizes our current knowledge of atmospheric oxygen.…
The authors address the currently available records indicating that atmospheric oxygen is undergoing nonlinear decline. The consensus in the research community is that the main reason for this decline is the combustion of fossil fuels (which is growing nonlinearly). However, the short length of the currently available records, alongside the technological and social uncertainties that may risk speed up oxygen depletion, raise questions about the time scale of the decline, in particular, when oxygen depletion may cause physiological impact on humans and animals. The authors analyze this uncertainty to postulate the near term impact of depleted atmospheric oxygen, and perform multidisciplinary complex modelling of oxygen with long-term horizon estimations.A simple yet revolutionary approach to improving your body's oxygen use, increasing your health, weight loss, and sports performance--whether you're…
a recovering couch potato or an Ironman triathlon champion. With a foreword by New York Times bestselling author Dr. Joseph Mercola.Achieve more with less effort: The secret to weight loss, fitness, and wellness lies in the most basic and most overlooked function of your body--how you breathe. One of the biggest obstacles to better health and fitness is a rarely identified problem: chronic over-breathing. We often take many more breaths than we need--without realizing it--contributing to poor health and fitness, including a host of disorders, from anxiety and asthma to insomnia and heart problems.In The Oxygen Advantage, the man who has trained over 5,000 people--including Olympic and professional athletes--in reduced breathing exercises now shares his scientifically validated techniques to help you breathe more efficiently. Patrick McKeown teaches you the fundamental relationship between oxygen and the body, then gets you started with a Body Oxygen Level Test (BOLT) to determine how efficiently your body uses oxygen. He then shows you how to increase your BOLT score by using light breathing exercises and learning how to simulate high altitude training, a technique used by Navy SEALs and professional athletes to help increase endurance, weight loss, and vital red blood cells to dramatically improve cardio-fitness.Following his program, even the most out-of-shape person (including those with chronic respiratory conditions such as asthma) can climb stairs, run for a bus, or play soccer without gasping for air, and everyone can achieve: Easy weight loss and weight maintenance Improved sleep and energy Increased concentration Reduced breathlessness during exercise Heightened athletic performance Improved cardiovascular health Elimination of asthmatic symptoms, and more.With The Oxygen Advantage, you can look better, feel better, and do more--it's as easy as breathing.The secret to your health, fitness and overall wellbeing lies in the most basic and overlooked aspect of your workout:…
how you breathe. Developing body strength while ignoring breathing strength is counterproductive. In The Oxygen Advantage, Patrick McKeown combines his successful breathing exercises with techniques designed to simulate high-altitude training in a highly successful programme that will significantly improve anyone's health but will also empower athletes to improve their sports performance. These scientifically validated exercises have the potential to drastically improve your overall fitness, whether you are a habitual couch potato or an Ironman triathlon champion. These easy-to-use techniques can help to reduce your breathlessness, improve your sleep as well as reduce anxiety and stress. Drawing on his own experiences as an ex-asthmatic and the work he has done to help athletes and asthma sufferers alike to achieve greater fitness, Patrick shows you the key to a healthier, fitter you.
