Being alert to excessive sleepiness and/or insomnia in shift workers may prevent comorbidities and accidents that can occur as a consequence of shift-worker disorder (SWD). Not all shift workers develop SWD. Thus, identification of sensitivity to shift work may be facilitated by asking patients whether they find it difficult to function in the absence of consolidated sleep, prefer to be active ...

OBJECTIVES Sternal wound dehiscence (SWD) after cardiac surgery is a rare but serious condition associated with considerable costs and morbidity. We sought to evaluate the results of the introduction of vacuum-assisted closure (VAC) therapy in the management of sternal wound dehiscence, compared with those of previous conventional treatments. METHODS We retrospectively collected 7148 patients...

The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is widely distributed in temperate and subtropical Asia (Delfinado and Hardy 1977) and has recently been found in the eastern United States and western North America (Steck et al. 2009; Walsh 2009; Beers et al. 2010). The fly is of concern to fruit growers because of its ability to attack ripening soft fruits. It is considered t...

When supervising aircraft, air traffic controllers need to know the current wind magnitude and direction since they impact every flying vessel. The wind may accelerate or slow down an aircraft, depending on its relative direction to the wind. Considering several aircraft flying in the same geographical area, one can observe how the ground speed depends on the direction followed by the aircraft....

Computer model experiments are applied to analyze hypoxia reductions for opposing wind directions under various speeds and durations in the north–south oriented, two-layer-circulated Chesapeake estuary. Wind’s role in destratification is the main mechanism in short-term reduction of hypoxia. Hypoxia can also be reduced by wind-enhanced estuarine circulation associated with winds that have down-...

Doppler lidars are frequently operated in a mode referred to as arc scans, wherein the lidar beam scans across a sector with a fixed elevation angle and the resulting measurements are used to derive an estimate of the nminute horizontal mean wind velocity (speed and direction). Previous studies have shown that the uncertainty in the measured wind speed originates from turbulent wind fluctuation...

The effect of a continuous-wave (cw) laser based anemometer's probe volume on the measurement of wind turbulence is studied in this paper. Wind speed time series acquired by both a remote sensing cw laser anemometer, whose line-of-sight was aligned with the wind direction, and by a reference sensor (sonic anemometer) located in the same direction, were used. The spectral transfer function, whic...

A mathematical model is used to simulate the effect of wind conditions on men's and women's 200-m times. Four questions are posed: What is the effect of constant winds on 200-m performance? What is the effect of varying wind speed and direction? What is the effect of the lane allocation? How do wind conditions affect the velocity profile? The race is simulated for winds with constant velocity a...

Air pollution is one of the most important environmental problems in the town of Bor, situated in the eastern of Serbia. The main source of air pollution with sulphur dioxide, heavy metals and other toxic and carcinogenic elements present in particulate matter (PM) and aero sediments is the Copper Mining and Smelting Complex Bor. The distribution of air pollutants is mainly determined by the co...
