conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

Strain rate dependent deformation behaviours of selective laser melted Alloy 718 (IN718) are systematically studied at 550 and 650 °C by slow strain testing, with a forged counterpart as reference. Selective IN718 shows significant susceptibility to intergranular cavitation, resulting in ductility degradation decreasing rate. Detailed fractography cross section inspections employed identify the...

Copper is the intended canister material for disposal of spent nuclear fuel in Sweden. At repository depth groundwater may contain dissolved sulfide. The main goal this work to study tendency stress corrosion copper sulfide solutions and examine influence various experimental parameters on corrosion. Slow strain rate testing was performed test rods with 1.0 mM pH kept near neutral phosphate or ...

Variability in growth rate was observed among S strain isolates of Aspergillus flavus from western Arizona. Isolates were grouped into fast and slow growing biotypes and compared for radial growth, and sclerotia, spore, aflatoxin, and pectinase production. Slow and fast biotypes were distributed equally among three collection areas with 35% of 300 S strain isolates classified as the slow biotyp...

Experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304H stainless steel. Three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the DRX critical strain: strongly strain dependent softening by SRX alone with softening kinetics control...
