run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
introduction iran is located in a semi arid region of the world. in recent years, dramatic changes in the form of increasing in maximum temperature and severe droughts have damaged water resources, local forests and agriculture. in the mid- and high latitudes of the northern hemisphere the warmest years have been recorded in recent decades (ipcc, 2007). in order to fully understand the climatic...
introduction long-term climate records are valuable for environmental planning, and tree rings allow records to extend to the time before the establishment of weather stations. for a better understanding of the past climate fluctuation and to mitigate the effect of climate fluctuation, dendroclimatic reconstructions have been applied in many parts of the world. inter annual variations of climat...
The temporal dynamics of dew formation in cold desert-shrub ecosystems are still poorly understood. We examined dew and its abiotic controls in a shrubland in northwestern China with continuous eddy-covariance measurements of latent heat fluxes gathered over the growing-season of 2012. The dew amount was larger in mid-summer than in spring and autumn, but the dew duration was shorter in summer ...
