In the 20th century air transport has developed into a safe, reliable and economic means of transportation for passengers, cargo and mail. In the next two decades, the air transport is forecasted to double. To enable this expansion to occur within the limited airspace, with the limited number of airports and runways and with the increasing requirements with respect to safety, noise and emission...

[1] During the 2008 Olympic and Paralympic Games in Beijing (from 8 August to 17 September), local authorities enforced strong measures to reduce air pollution during the events. To evaluate the direct effect of these measures, we use the tropospheric NO2 column observations from the satellite instruments GOME-2 and OMI. We interpret these data against simulations from the regional chemistry tr...

it is difficult to prevent accidents in the transport of hazardous goods, so the development of strategies for managing crisis situations and the optimization of action plans are important. the crisis situation is a continuous event in time when its evolution is unpredictable because it depends on a whole of complex factors resulting from the environment of the crisis. decision making in crisis...

Air quality simulations and forecasting using photochemical transport models require detailed information of the emissions in the area under investigation. Due to the wide range of space and time scales involved in the physical and chemical processes of air pollution phenomena, a need to perform air quality simulations over larger regions, at finer grid resolutions, using more emissions sources...

OBJECTIVE Decompression illness (DCI) is a potentially lethal complication of diving and may occur far from hyperbaric facilities. The need for prompt transport to a hyperbaric facility often involves air medical transport, but this may exacerbate DCI. The authors reviewed available literature to establish evidence-based transport strategies utilizing safe altitudes for patients, with DCI. ME...

BACKGROUND Post-craniotomy intracranial air can be present in patients scheduled for air ambulance transport to their home hospital. We aimed to assess risk for in-flight intracranial pressure (ICP) increases related to observed intracranial air volumes, hypothetical sea level pre-transport ICP, and different potential flight levels and cabin pressures. METHODS A cohort of consecutive subdura...
