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...
abstract different definitions have been proposed for soil quality. various soil properties have been suggetsted as soil quality indices by researchers. this research was conducted to study the relationship between slope of retention curve at its inflection point (s index) and other soil physical quality indices, because the reserches between s index and soil physical properties are little. thi...
The present study conducted to investigation the forage quality and germination status of Capparis spinosa in Niatak Hirmand rangelands. Forage quality indices were analyzed by four replications on three phenological stages (vegetative, flowering and maturity stages) randomly. The experiment included 19 treatments to improve seed germination condition. Treatments included physical such as scrap...
our main objective in the present study was to assess the spatial variation of chemical and physical water properties. prior to the design of groundwater quality monitoring networks, it is essential to investigate the spatial structure of the groundwater quality variables. a case study is presented which used ground water quality observations from groundwater domestic wells in the dameghan, ira...
Swimming is considered one of the most conventional recreational activities for both leisure and exercising. Swimming pools have either public or private usage. Nevertheless, if the water of the swimming pools is polluted and is not identified on time, it could result in the transmission of various diseases to the people who use them. Therefore, the main objective of this study was to assess th...
