abstract in this research, a radial basis function artificial neural network (rbf-ann) model was developed to predict the hot deformation flow curves of api x65 pipeline steel. the results of the developed model was compared with the results of a new phenomenological model that has recently been developed based on a power function of zener-hollomon parameter and a third order polynomial functio...

to investigate the hot deformation behavior of 17-7 ph stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oc and strain rates of 0.001 s-1 to 0.1 s-1. accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

background clindamycin is a frequently used antimicrobial therapeutic medicine used for the treatment of skin and soft tissue infections caused by staphylococcus aureus strains. resistance to this antibiotic is either constitutive or inducible. constitutive resistance to clindamycin could be detected by standard susceptibility testing methods. inducible clindamycin resistance could not be detec...

The chlorate-resistant mutant cr88 is defective in photomorphogenesis, as shown by the phenotypes of long hypocotyls in red light and yellow cotyledons under all light conditions. A subset of light-regulated genes is expressed at subnormal levels in cr88. To analyze further the role that CR88 plays in photomorphogenesis, we investigated the genetic interactions between cr88 and mutants of two o...
