c O N S I D E R A B L E expe r i e n c e has been gained with sealed cabin atmospheres incidental to twenty-four-hour balloon-borne animal flights above 100,000 ~feet. la The temperature and pressure problems encountered while floating a t this altitude are space equivalent, corresponding closely to the conditions that would be encountered by an orbiting satellite. Design of a manned, sealed ca...

Electric drive vehicles (EDVs) have complex thermal management requirements not present in conventional vehicles. In addition to cabin conditioning, the energy storage system (ESS) and power electronics and electric motor (PEEM) subsystems also require thermal management. Many current-generation EDVs utilize separate cooling systems, adding both weight and volume, and lack abundant waste heat f...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...

Data pertaining to nonmotion factors affecting ride quality of transport aircraft have been obtained as part of NASA in-house and sponsored research studies carried out onboard commuter-airline and research aircraft. From these data, quantitative effects on passenger discomfort of seat width, seat legroom, change in cabin pressure, and cabin noise are presented. Visual cu_ effects are also disc...

projection display, is a room-sized, five-screen system that can display both computer graphics and video images. Several Cabins connected via a broadband network form the Cabinet system. Cabinet includes video avatars—a key new technology for sharing virtual worlds. Using video avatars, we have experimentally evaluated the ability to express positional information between distant users. I mmer...

OBJECTIVE This paper reviews secondhand smoke (SHS) exposure and diseases and symptoms of the upper airway, including the sinuses. Risks to flight attendants, who were occupationally exposed until smoking was banned on all flights, are emphasised. DATA SOURCES A systematic database search was conducted; the US Surgeon General's reports and other major reviews were evaluated. Literature summar...
