Kinetics of fine wet grinding in a laboratory ball mill
(ELSEVIER SCIENCE SA, 2001)The kinetics of batch wet grinding of quartz from a feed of 600 x 425 mum to a product of 80% less than 8 mum have been determined using sieving and laser diffractometer sizing for size analysis. A dispersing agent was ... -
On (*)-(sigma, T)-Lie ideals of (*)-prime rings with derivation
(HACETTEPE UNIV, FAC SCI, 2018)Let R be a (*)-prime ring with characteristic not 2, U be a nonzero (*)- (sigma, tau)-Lie ideal of R and d be a nonzero derivation of R. Suppose sigma, tau be two automorphisms of R such that sigma d = d sigma, tau d = d ... -
Changes in the nitric oxide system of rat myometrium during midgestation and delivery at term
(ACADEMIC PRESS LTD, 1998)The aims of this study were to investigate whether a nitric oxide (NO) system is present in the pregnant rat myometrium and whether it differentially inhibits myometrial contractility during midgestation and delivery at ... -
