Abstract Successful weather forecasts on subseasonal time‐scales can support societal preparedness and mitigate the impacts of extreme events. Heatwaves in particular can, certain cases, be predicted several weeks advance. Heatwave predictability is commonly assessed terms heatwave intensity. In addition to intensity, we assess onset duration, which are crucial components early‐warning systems ...

 Two relatively simple analytic Models for investigation of fast ignition dynamics are developed, that are the subsonic and the supersonic models. On the basis of the subsonic model, which a pre-compressed fuel of density is heated by a subsonic thermal wave, the beam energy and the intensity required for ignition is closely related to proton range. Whereas, on the basis of supersonic model, fo...

By increasing the intensity of rainfall, runoff, which is considered as a very important factor in soil erosion process, occurs. Climate, geometrical characteristics of watershed, geological formations, soil, vegetation and land use are among factors affecting runoff generation. Although in plots under rainfall simulation, the experiment time is more limited and the effect of rainfall duration ...

BACKGROUND Physical activity (PA) is associated with lower risk for non-communicable diseases and mortality. We aimed to investigate the prospective association between PA and all-cause and cause-specific mortality, and the impact of other potentially contributing factors. METHOD Data from the community-based Hordaland Health Study (HUSK, 1997-99) were linked to the Norwegian Cause of Death R...
