A Novel Continuous-Discontinuous Multi-Field Numerical Model for Rock Blasting
Applied Sciences, 2022 During blasting, rock failure is caused by blasting wave and explosive gas pressure, as a multi-field coupled process. Most numerical models focus on the effect of blasting wave where the gas pressure is commonly accounted for by empirical relations ...

Eastern-European Journal of Enterprise Technologies, 2019 , rather than rigid, by installing a specia-lized device – a damper between a body and a deck. To simulate the dynamic loading of a wagon body taking into consideration the proposed technical solutions, a mathematical model has been constructed and the ...

Effects of cyclic loading on lateral bearing capacity of single pile in silty seabed
Yantu gongcheng xuebaoUnder larger wave loading, the bearing capacity of marine single pile foundation will be reduced, even instability occurs. A series of undrained shear triaxial tests on the remolded marine silt in Hangzhou Bay are carried out by means of the GDS triaxial

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild
