AIMS Exercise stress testing is often used as the initial non-invasive diagnostic test in symptomatic patients with suspected obstructive coronary artery disease. Positive standard ECG criteria are quite specific for obstructive coronary artery disease, but there may be a substantial number of false negative tests, including patients with severe coronary artery disease. Also, exercise stress te...

This work presents the effects of strain rate on the tensile properties and fracture morphologies of AHSS-DP 350/600 subjected to LSP. Fatigue crack growth test was performed to evaluate fatigue behavior in the metallic plate of AHSS-DP350/600. However, this material is used in automobile industry and enhancing it fatigue resistance is a challenge in material engineering. In order to evaluate a...

the available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. in the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. these non-uniform ...

cabbage leaf miner scaptomyza flava (fallen) (l)iptera: drosophilidae) is a native and oligophagous leaf miner insect on cruciferous plants (brassicaceae). it occurs in many parts of the world and throughout khuzestan. the relationship between feeding and ovipositional preferences of insect, and host plant suitability on seven host plant species (cauliflower brassica oleracea var. botryds, ...
