Book Description
The importance of safety in any scientific endeavor is never in question. However, when cryogenic temperatures are involved, safety is especially important. In addition to observing the normal precautions, one must also take into account the variations of physical properties that occur at low temperatures. At these tempera tures, some properties not only exhibit large differences from their normal values but also can vary widely over a small temperature range. Before any cryogenic project is started, a thorough knowledge of the possible hazards is necessary. Only in this way can the safest operation be attained. Over the hundred-year history of cryogenic research, this has been shown to be the case. Keeping this requirement in mind is an essential ingredient in the quest for accident-free work. The past four or five decades have seen a great expansion of cryogenic technology. Cryogenic liquids, such as oxygen, nitrogen, hydrogen, and helium, have become commonly used in a number of different applications and are easily available in any part of the United States and, indeed, almost anywhere in the world. Not only are these liquids available, they have become less expensive and also available in ever larger quantities. As quantities increase, so also do the conse quences of mishaps. The future seems to hold promise of ever larger and more widespread use of the common cryogens. Thus, the importance of safety also increases as time progresses.

Book Description
In petroleum engineering, liquid nitrogen can be used to aid in fracturing the formation rock because of its extremely cryogenic temperature. With the development of new jet technology in recent years, liquid nitrogen is considered as a promising jet medium to exploit oil and gas. The first chapter of this book provides an impact pressure and parametric sensitivity analysis of the numerical simulation of liquid nitrogen. In the second chapter, the uses of liquid nitrogen in a completely different sphere are explored, particularly its use for the storage of human cells and tissues for transplantation. Finally, liquid nitrogen is one of the cryogenic fluids most used for cryopreservation of animal germoplasm; low temperature preservation of oocytes, sperm and embryos is a fundamental cornerstone of assisted reproductive technologies. The last chapter examines the mathematical prediction of cooling rates during cryopreservation of reproductive cells in liquid nitrogen.

Book Description
This book describes the current state of the art in cryogenic safety best practice, helping the reader to work with cryogenic systems and materials safely. It brings together information from previous texts, industrial and laboratory safety polices, and recent research papers. Case studies, example problems, and an extensive list of references are included to add to the utility of the text. It describes the unique safety hazards posed by cryogenics in all its guises, including issues associated with the extreme cold of cryogenics, the flammability of some cryogenic fluids, the displacement of oxygen by inert gases boiling off from cryogenic fluids, and the high pressures that can be formed during the volume expansion that occurs when a cryogenic fluid becomes a room temperature gas. A further chapter considers the challenges arising from the behavior of materials at cryogenic temperatures. Many materials are inappropriate for use in cryogenics and can fail, resulting in hazardous conditions. Despite these hazards, work at cryogenic temperatures can be performed safely. The book also discusses broader safety issues such as hazard analysis, establishment of a safe work culture and lessons learned from cryogenic safety in accelerator labs. This book is designed to be useful to everyone affected by cryogenic hazards regardless of their expertise in cryogenics.

Book Description
Physics of Cryogenics: An Ultralow Temperature Phenomenon discusses the significant number of advances that have been made during the last few years in a variety of cryocoolers, such as Brayton, Joule-Thomson, Stirling, pulse tube, Gifford-McMahon and magnetic refrigerators. The book reviews various approaches taken to improve reliability, a major driving force for new research areas. The advantages and disadvantages of different cycles are compared, and the latest improvements in each of these cryocoolers is discussed. The book starts with the thermodynamic fundamentals, followed by the definition of cryogenic and the associated science behind low temperature phenomena and properties. This book is an ideal resource for scientists, engineers and graduate and senior undergraduate students who need a better understanding of the science of cryogenics and related thermodynamics. - Defines the fundamentals of thermodynamics that are associated with cryogenic processes - Provides an overview of the history of the development of cryogenic technology - Includes new, low temperature tables written by the author - Deals with the application of cryogenics to preserve objects at very low temperature - Explains how cryogenic phenomena work for human cell and human body preservations and new medical approaches
