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”.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 world on fire: a heretic, an aristocrat, and the race to discover oxygen
Par Joe Jackson. 2005
Describes the near-simultaneous eighteenth-century discovery of oxygen by two scientific rivals, Englishman Joseph Priestley and Frenchman Antoine-Laurent Lavoisier. Focuses on…
their research and its implications for the new science of chemistry. Outlines the political and social events that forced Priestley to flee England and sent Lavoisier to the guillotine. 2005Ventilatory Support and Oxygen Therapy in Elder, Palliative and End-of-Life Care Patients
Par Antonio M. Esquinas, Nicola Vargas. 2020
This book provides readers with a comprehensive and up-to-date guide to non-invasive mechanical ventilation in palliative medicine, focusing on why…
and when it may be necessary. Physicians will find a practical guide to this specific context, particularly focused on pulmonary function and physiology in the elderly, and on ventilatory management in surgery and chronic stable conditions. The book provides detailed information on the rationale for invasive and non-invasive ventilation, the different modes of ventilation, indications and contraindications, prognostic factors, and outcomes. It addresses in detail the role of postoperative mechanical ventilation following various forms of surgery, and discusses key aspects of withdrawal from ventilatory support. Attention is also devoted to the use of mechanical ventilation within and beyond the ICU. The concluding part of the book focuses on important topics such as ethics, legal issues, home mechanical ventilation, drug therapy, rehabilitation and end-of-life.Its multidisciplinary approach, bringing together contributions from international experts in different specialties, ensures that the book will be of interest to a broad range of health professionals involved in the management of older patients admitted to the ICU, including intensivists, anesthesiologists, and geriatricians.
