This report is intended to acquaint personnel involved in the design, inspection, and maintenance of civil transport oxygen systems with the human respiratory requirements and oxygen system design considerations necessary to effect an interface and provide acceptable high-altitude life support. Simplified explanations and language that should be understandable by lay and semiprofessional engineering personnel are used, with references to sources of more detailed information. The oxygen system designer is directed to applicable Federal Aviation Regulations pertaining to oxygen systems and, where regulatory guidance does not exist, directs the reader to applicable oxygen equipment industry practices, standards, and information reports.

The relationship between resources and development is the pivot around which the present study revolves. Focussing on the process of resource creation and utilization it emphasizes the need of equitable development integrating local needs, resources, people and functions. The resource exploitation and their utilization are two independent economic activities influenced by different algorithms and usually have manifested in core-periphery relationship. Reviews the persistent problems of economic development in perspective of exploitation of natural resources with the objective to provide some clues for occurrence and persistence of regional disparities and for suggesting a development model synchronising both the resource management and environmental protection.

Although poor air quality is probably not the hazard that is foremost in peoples' minds as they board planes, it has been a concern for years. Passengers have complained about dry eyes, sore throat, dizziness, headaches, and other symptoms. Flight attendants have repeatedly raised questions about the safety of the air that they breathe. The Airliner Cabin Environment and the Health of Passengers and Crew examines in detail the aircraft environmental control systems, the sources of chemical and biological contaminants in aircraft cabins, and the toxicity and health effects associated with these contaminants. The book provides some recommendations for potential approaches for improving cabin air quality and a surveillance and research program.
