Diving Physics with Bubble Mechanics and Decompression Theory in Depth


Book Description

This book focuses on physics and associated mathematical relationships. Basic principles are first presented, and then practical applications and results are detailed. The intent here is to present a working view of physical phase mechanics, then followed by application to decompression theory in diving. It is directed toward the diver and reader with a basic understanding of decompression. Basically the mechanics of tissue gas exchange, bubbles and nucleation, supersaturation, perfusion and diffusion, and related mechanisms are discussed. The targeted audience is especially the doctor or physiologist, physicist, chemist, mathematician, engineer or biologist by training and also the commercial diver, technical diver, instructor, hyperbaric technician, underwater researcher, looking for greater detail.




Science of Diving


Book Description

While the effects of pressure change are readily quantified in physics, chemistry, and engineering applications, the physiology, medicine, and biology of pressure changes in living systems are much more complicated. This complex science translated to technical diving is discussed in a five-part series, with each topic self-contained and strategical

Biophysics and Diving Decompression Phenomenology


Book Description

The biophysics of diving and decompression in the human body are complex. The average individual experiences atmospheric pressure swings of 3% at sea level and over 20% at altitudes greater than a mile. Divers and their equipment can experience compressions and decompressions in orders of greater magnitude than pressures outside water, all within considerably shorter time spans. The understanding of the mechanics behind diving is based on absolute pressure and pressure changes. While these mechanics are readily quantified in physics, chemistry, and engineering applications, the physiological and medical aspects of pressure changes in living systems need to be understood clearly to assess the safety of routine divers. This monograph is a compilation of a body of knowledge on biophysics, gas transport, bubble studies and physiological models used for diving and hyperbaric applications. Information in the monograph is divided into three parts that cover biophysics and models, data correlation and validation approaches and practical applications, respectively. The book is a useful resource for researchers and maritime professionals who wish to understand the biophysics behind underwater diving and decompression for the purpose of maritime operations as well as diving simulation applications.




Diving Science... Revisited


Book Description

Diving Science...Revisited is like no other diving text, including its predecessor, Diving Science. Amplified with figures, tables, and photos in color, this book includes four unique and innovative parts amplified by nine contributors. - Medical problems of diving (MPD) are discussed from stimulus-response perspectives in the phase of a dive in which they are likely to occur. - MPD are explained by how they affect the human diver whether physical, physiological, psychological, and/or lack of awareness. - A variety of diving types and situations from breath-hold to rebreather, from children to women to older aged adults, from cold water to cave, and from deep altitude to diving with handicaps are described in individual chapters with their merits, hazards, and necessary precautions for safe diving. - Part IV contains a concise summary of the MPD from seven different perspectives ranging from the significance of the problem to when to return to diving. - Part V consists of a rhetorical question for each of the first four parts with bullet points that recap the subjects covered in each chapter. This book describes the positive as well as undesirable ways divers' interact with the aquatic environment. It is especially recommended for the following: -Diving instructors and supervisors - Those involved with clinical applications of hyperbaric oxygen therapy - Those engaged in diving-associated marine biology and underwater missions - All divers, whether novice or advanced, who want to advance their knowledge about the science and medical challenges of diving.




Basic Decompression


Book Description

"3rd Edition of BASIC DECOMPRESSION THEORY AND APPLICATION takes all rudiments of decompression theory and phase mechanics to considerable depth, while focusing on diving applications in a historical perspective. Topics span many disciplines, and the targeted audience is the commercial diver, hyperbaric scientist, doctor, physical scientist, technical diver, and dive instructor. The intent of the 3rd Edition is to present a working view of decompression in diving, mostly focusing on theory with application, including equations. The discussion is neither a medical nor physiological synthesis. Such aspects are simplified, and for some certainly oversimplified. Nonetheless, it is directed toward the diver and reader with some rudimentary understanding of decompression. Background in the physical or life sciences is helpful but certainly not necessary. Discussed are the mechanics of tissue gas exchange, bubbles and nucleation, supersaturation, perfusion and diffusion. Also included are chapters on "Mixed Gases and Decompression" - "Decompression Tables, Meters and Models" - "Decompression Risks and Statistics." References and numerical examples (with solutions) are included for more detail and extended diver analysis."--Publisher's website.

Reduced Gradient Bubble Model in Depth


Book Description

The intent of this book is to present a working view of the reduced gradient bubble model (RGBM), decompression mechanics, and applications to technical diving. The focus is RGBM theory and correlations with experiment, lab testing, field-testing, and data. It is directed to the reader with some rudimentary understanding of decompression. Dual phase mechanics, materials, and bubble phenomenology are linked, field testing, data, and validation arediscussed, and the physical couplings are presented. Extensive references are appended.Some have called it a revolution in modern diving. The RGBM has already gained widespread acceptance and popularity with growth in prominence, particularly in the deep, decompression, and mixed gas sectors. This is due to released Tables (NAUI), meter implementations (Suunto, Mares, Dacor, Plexus, Hydrospace, Plexus, Zeagle) computer software (GAP, ABYSS, RGBMdiving.com), testing, validation and wholesale positive results and feedback by real divers across all venues.Contents include:Computational Syntheses Results and ComparisonsMaterial Dynamics Deep Stops and HeliumCritical Phase Volume Limit Risk Analysis and ValidationRGBM Implementations




Mud, Muscle, and Miracles


Book Description

By the start of the 20th century, the U.S. Navy had developed a fledgling salvage capability. Today, under the aegis of the Supervisor of Salvage, the Navy routinely handles assignments around the world, guarding U.S. naval and maritime interests and responding to requests for assistance from our allies. Mud, Muscle, and Miracles takes its reader on a journey through the evolution of salvage--from the construction of a cofferdam to reveal battleship Maineat the bottom of Havana harbor in 1911 to the use of side-scan sonar and remotely operated vehicles to recover aircraft debris and complete vessels from the depths. The story is one of masterful seamanship, incomparable engineering, and absolute ingenuity and courage. It is also the history of one of our nation's longest-lasting public-private partnerships--that of the commercial salvage industry and the U.S. Navy. The second edition updates U.S. Navy salvage history through the beginning of the 21st century and chronicles 18 additional, precedent-setting marine salvage and deep-ocean recovery operations.
