The phospholipids of porcine spermatozoa were analyzed by a hydrolytic procedure directly after ejaculation, and after incubation for 120 min in vitro or in ligated uterine segments of females with induced estrus. Total phospholipid content of ejacul

We have examined the fatty acid substrate specificity of arachidonoyl-CoA synthetase from human platelet membranes. A variety of positional isomers and chain-length analogs of arachidonic acid [20:4(5, 8, 11, 14)] were synthesized, and assayed for th

We present a Monte Carlo (MC) model of [OI] 6300 A and [SII] 6716 A emission from Io entering eclipse. The simulation accounts for the 3-D distribution of SO 2 , O, SO, S, and O 2 in Io’s atmosphere, several volcanic plumes, and the magnetic field

Staphylococcal scalded skin syndrome is the term used for a spectrum of primarily neonatal blistering skin diseases caused by the exfoliative toxins, ETA and ETB, of Staphylococcus aureus. Despite 25 y of research, the toxins' mechanism of action is

The hot plane strain compression test has been used for the determination of stress - strain curves at hot working temperatures. These curves are used for the establishment of the high temperature mechanical constitutive equations which are an essent

The patterns of strain which occur in the axisymmetric compression test when it is used for the estimation of the structural changes occurring during hot working are analysed. The analysis is conducted by numerical (finite element viscoplastic) metho

The paper describes the shot peening process and derives expressions for the indentation of surfaces by single shot impacts. These are supplemented by analysis of surface coverage and an assessment of the sources of residual stress. The high strain r

The paper investigates the use of the hot axisymmetric compression test for the determination of the hot working properties of alloys. Qualitative analysis shows that stress determinations from the test are subject to systematic errors. These arise f
