Abstract Orthotropic steel decks (OSDs) are easily subjected to fatigue cracking under the cyclic vehicle loading, and arc notch between diaphragm U-rib is one of typical details. The strain values three measuring points at in a bridge were monitoring obtain stress time histories. Then, amplitudes damage degrees analysed. It was found that this detail tension–compression stress. maximum amplitu...

Background and Purpose: JV-substituted analogues of L-arginine are potent and selective inhibitors of nitric oxide synthase(s). The present study was designed to determine the effects of these analogues on the vascular smooth muscle of isolated canine basilar arteries. Methods: Basilar artery rings without endothelium were suspended for isometric tension recording in Krebs-Ringer bicarbonate so...

Abstract In this study, a new method for determining the material parameters of cyclic plasticity is presented. The can be applied to evaluate model from any loading histories measured experimentally. experimental data require basic processing only utilized. calibrate different elastoplastic models such as Chaboche–Rousselier (Ch–R) constitutive equation or other formulations which use rules is...

Abstract Cross-laminated timber (CLT) wall panels are commonly connected to the floor or foundation using metal connections, which play a critical role in determining seismic performance and energy dissipation of CLT shear walls. In this study, comprehend tension–shear coupling effect wall-to-floor angle bracket connections under loads, both monotonic cyclic tests were conducted on brackets tha...

Cyclic contraction and relaxation of plasmodial strands of Physarum polycephalum were measured under both isotonic and isometric conditions, and their relation to changes in microfilament (MF) morphology was investigated. The contraction-relaxation rhythm of a strand segment was insignificant and irregular immediately after isolation from the mother plasmodium. It became regular half an hour la...
