The recent widespread of the new Mexican flu and SARS show the high dependency on contemporary traveling patterns. The air transport network is recognized as an important channel of epidemic propagation for different diseases. In order to predict epidemic spreading and the influence of protection measures, a mathematical model of the Susceptible Infected Susceptible (SIS) type is used. We compa...
A modeling framework was proposed to investigate the impact of trans-boundary air pollutant transport on regional air quality. This was based on a combination of the HYSPLIT trajectory model, the CAMx air quality model, and the MM5 meteorological model. The examination of atmospheric PM10 pollution in Guangzhou within the Pearl River Delta (PRD) region of southern China was used as a case study...
A new Lagrangian method is proposed to quantify the transport of ozone – or any other atmospheric constituent – by objectively-defined air-masses. In the framework of mesoscale modelling, this method is an alternative to classical Eulerian or trajectorybased methods, which suffer from many drawbacks at this scale. The elementary 5 air-parcels are tagged with their initial location (what is made...
Air transport of infants in incubators should be undertaken in a manner that is safe for both staff and infant and satisfies all directives by appropriate regulatory bodies. In Scotland during the last two years, certification of an infant incubator system for use in both rotary and fixed wing aircraft has been accomplished. This is a report of the issues addressed during this project, which wi...
Public reliance on air transport industry as one of burgeoning factors of world economy is based on aviation safety. But the current challenge of aviation industry is the lax surveillance of safety standards by related governments which is basically due to illegal registration of aircraft. This article with reliance to the position of legal elements in achieving aviation safety has analyz...
INTRODUCTION A growing number of individuals with significant medical histories travel for business and holidays. Precise anticipation and stratification of transport-relevant illness severity in the planning stage of an air medical evacuation is crucial for mission success and patient safety. METHODS We developed a staging system (ie, Stratification of Air Medical Transport by Expression of ...
Air transport industry has gradually increased its share of global passenger and freight traffic, and this trend has accelerated in the last 40 years. For the past decade, air-freight traffic growth has outpaced air passenger traffic growth by 1-2% each year. In the past, air-freight sector offered limited services, with heavy reliance on several intermediaries and a significant dependence on a...
