Modelling of overall plastic deformation in rubber-toughened polymers
In this paper, we provide a constitutive model for overall (macroscopic) plastic deformation behavior in a rubber-toughened polymer blend. A porous plasticity theory is employed as a basis for the constitutive...

Deposition of Diamond-Like Carbon Film in a Closed-Space CH4 RF Plasma
Deposition of diamond-like carbon (DLC) film and mass spectrometry measurements were carried out in a closed-space CH4 rf (13.56 MHz) plasma (without both gas injection and vacuum pum** during the process). At ...

Alterations of Calcium/Calmodulin-Dependent Protein Kinase II Activity in Ischaemia-Induced Neuronal Death and Neuronal Protection Against Ischaemia in the Gerbil Hippocampus
To clarify the relation between neuronal protection against ischaemia and calcium/calmodulin-dependent protein kinase II (CaM kinase II) activity, we investigated temporal alterations of the kinase activity i...

Endothelial-cell injury of the basilar artery caused by ethanol infusion in dogs
This study in mongrel dogs was designed to observe the effects of ethanol on both endothelial cells of the basilar artery and brain function. By use of sterile surgical technique, a super-selective catheter wa...

Expression of intercellular adhesion molecule 1 (ICAM-1) on the cerebral artery following subarachnoid haemorrhage in rats
In order to study how immune-inflammatory responses are involved in the pathogenesis of cerebral vasospasm after subarachnoid haemorrhage (SAH), the kinetics of expression of the intercellular adhesion molecul...
