UNLABELLED Quick information on airborne infectious disease transmission in airliner cabins is essential to reduce the risk of infection of passengers and crew members. This investigation proposed a one-dimensional analytical model that can predict the longitudinal transmission of airborne contaminants or disease viruses inside an airliner cabin. The model considered both diffusive and convecti...

Statistical data on road safety indicates that drivers between ages 16-24 account for a high level of accidents and fatalities; in Israel 25% severe accidents and 5% fatalities occur during the first two years of driving, and young novice drivers are 10-times more likely to be in an accident during their first 500 miles. Ironically, the most common violations for this group are speeding (37%) a...

in this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. to achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. the length of gasper air flow was compared with the distance between gasper outlet and...

Five persons contracted tick-borne relapsing fever after staying in a cabin in western Montana. Borrelia hermsii was isolated from the blood of two patients, and Ornithodoros hermsi ticks were collected from the cabin, the first demonstration of this bacterium and tick in Montana. Relapsing fever should be considered when patients who reside or have vacationed in western Montana exhibit a recur...

Worldwide people are exposed to toxic ultrafine particles (UFP, with diameters (dp) less than 100 nm) and nanoparticles (NP, dp < 50 nm) under a variety of circumstances. To date, very limited information is available on human exposure to freshly emitted UFP and NP while traveling on major roads and freeways. We report in-cabin and outdoor measurements of particle number concentration and size ...

BACKGROUND Minimally invasive surgery in the field of traumatic vascular injury diagnosis and treatment has achieved good results. This study was designed to determine whether pre-hospital emergency intervention is feasible for vascular injury in a field intervention cabin under the condition of war or a disaster site. METHODS Different types of animal experiments of vascular injury intervent...

Abstract During the high-speed flight of aircraft, cabin body will bear aerodynamic loads, engine thrust structural and equipment component mass inertial loads. At same time, thermal loads be generated due to high speed flight. With development hypersonic aircraft technology, demand for multi-field coupling test is more common. Therefore, it necessary carry out technical verification mechanics ...

Inhalable particulate pollution has adverse effects on human health. Many studies have been conducted to investigate levels and risks of exposure in public transit, but scant attention paid variations the among different positions inside cabin. Differences can be observed transit vehicles, like passenger density activities, which may lead differentiated between positions. Therefore, this study ...

A transient heat transfer mathematical model for the prediction of temperature distribution in the car body during primer baking has been developed by considering the thermal radiation and convection in the furnace chamber and transient heat conduction governing equations in the car framework. The car cockpit is considered like a structure with six flat plates, four vertical plates representing...

in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...
