Assessing the impact of the coronavirus disease 2019 (COVID-19) on air transportation is essential for policymakers and airlines to prevent their widespread shutdown. The panel data observed from January 20, 2020, to April 30, 2020, were used to identify the impact of COVID-19 and the relevant control measures adopted on China's domestic air transportation. Hybrid models within negative binomial models were employed to separate the temporal and spatial effects of COVID-19. Temporal effects show that the number of new confirmed cases and the control measures significantly affect the number of operated flights. Spatial effects show that the network effect of COVID-19 cases in destination cities, lockdown, and adjustment to Level I in the early stages have a negative impact on the operated flights. Adjustment to Level II or Level III both has positive temporal and spatial effects. This indicates that the control measures adopted during the early stage of the pandemic positively impact the restoration of the aviation industry and other industries in the later stage.

Few epidemiological studies have investigated associations between anthropogenic heat emissions (AE) and serum lipids. We recruited 15,477 adults from 33 communities in northeastern China in 2009. We estimated AE flux by using data on energy consumption and socio-economic statistics covering building, transportation, industry, and human metabolism.

Study Objectives: Reversal of warfarin-induced anticoagulation using prothrombin complex concentrate (PCC4) is more rapidly achieved than with traditional methods such as fresh frozen plasma (FFP). In many rural facilities the availability of both FFP and PCC4 has been limited. A tertiary hospital instituted a program to provide PCC4 to rural sites using an air transport team and pharmacy exchange.

The maritime transport sector poses significant air quality concerns, particularly in nearby cities. Ultrafine particles (UFP, diameter < 100 nm) are of particular concern due to their potential health impacts. This study measured particle number concentrations (PNC), size distributions (PNSD), and other pollutants including particulate matter (PM), nitrogen oxides (NO), black carbon (BC), sulfur dioxide (SO) and ozone (O), organic markers and trace elements at a major European harbor and an urban background (UB) location.

The Dzungarian Alatau in Central Asia and the Western Carpathians in Central Europe are exposed to anthropogenic sources of pollution that are impacting high-altitude mountain systems through long-range transport of emissions. Based on analyses of the autumn faeces of two species of marmots (Marmota baibacina from the alpine habitats of Zhongar Alatau National Park, Marmota marmota latirostris from the alpine habitats of the Western Tatras), we determined the environmental load of mercury and other chemical elements. Our results show significantly higher levels of total mercury amounts (p < 0.

Military medical transport is unique due to its frequent long-distance travel with limited supplies and capabilities. Military neonatal transport is perhaps even more niche, and descriptions in the literature are rare. A military neonatal team transported a 1-month-old former 26-week infant from a forward-deployed non-combat setting.
