Ladle shrouds(LS)and submerged entry nozzles(SEN)are flow control products used in continuous casting which transfer the liquid steel from the ladle to the tundish and further to the *** to the strongly different and quickly changing temperature conditions before and during steel casting,highly thermal shock resistant refractory materials are required which simultaneously save steel process energy.A new technology embeds a special liner into the refractory body inner surface to reduce the heat transfer through the LS/SEN *** better understand the function of this insulation layer a mathematical model was *** measurements carried out in the steel plant were compared with the simulation *** research results indicate potential heat loss reduction and performance improvements in the steelmaking process.

Dear Editor,The activating receptor DNAX accessory molecule-1(DNAM-1)plays an important role in T and natural killer(NK)cell-mediated cytotoxicity via the interaction with its ligands poliovirus receptor(PVR,CD155)and Nectin-2(CD112).Compared with peripheral blood NK cells,tumor-infiltrating NK cells show reduced expression of DNAM-1 across several solid tumors,including ovarian and breast cancer resulting in impaired NK cell *** studies reported an inverse correlation between DNAM-1 expression and its ligands in leukemic blasts and ovarian cancer[1].
