Development of a new creep testing equipment to obtain long-term deformation parameters of salt rocks
Creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. Current research involved designing and manufacturing of a new creep testing machine. The equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.To evaluate the equipment’s pe...

متن کاملNanogranular origin of concrete creep.
Concrete, the solid that forms at room temperature from mixing Portland cement with water, sand, and aggregates, suffers from time-dependent deformation under load. This creep occurs at a rate that deteriorates the durability and truncates the lifespan of concrete structures. However, despite decades of research, the origin of concrete creep remains unknown. Here, we measure the in situ creep b...
متن کاملBehçet's Disease Long Time after Sulfur Mustard Poisoning
Dear Editor, A 35-year-old man presented with severe headache and left sided hemiparesis since one day prior to admission. He reported frequent bouts of oral and genital aphthous ulcers, an attack of deep venous thrombosis of left lower extremity, one episode of right knee arthritis, and several attacks of headache, neck rigidity, and fever. He had been a victim of mustard-gas poisoning at the ...
متن کاملInvestigations of Thermocouple Drift Irregularity Impact on Error of their Inhomogeneity Correction
The article examines: (i) the reasons of error due to thermoelectric inhomogeneity of electrodes of thermocouples acquired during prolonged use; (ii) the neural network method of error correction based on a generalization of verification results in several temperature fields; (iii) the method of investigating the impact of changing the speed of the conversion characteristic drift of thermocoupl...
