In order to solve the support problem of deep soft crushed coal roadway, a concentrated cavern in mining station mine is taken as test object. Based on analysis and summary field observation data law rock pressure appearance, new technology relief anchoring with main body “initiative + borehole relief” proposed. This will carry out strong active shallow part surrounding excavate row low-density...
Abstract Determination of the stress state in concrete structures is a very important, but difficult task. In case new structures, it possible to easily instal measurement instruments which can provide important data as part real-time monitoring. However, evaluation stresses existing much more challenging. Currently, relief methods are well-established approach for actual structures. The so-cal...
The relationship between the crack nucleation and stress-induced martensitic transformation in the retained massive austenites (RM’s) of austempered ductile irons (ADIs) was examined in detail by carrying out tensile tests and scanning electron microscope (SEM) observations for an ADI material. The SEM observations revealed that cracks were not nucleated in the peripheral regions of graphite no...
BACKGROUND Defense Force workers engaged in disaster relief activities might suffer from strong psychological stress due to the tasks that they had been involved. We evaluated how living environments, work environments, and individual factors psychologically affect those who engaged in disaster relief activities.

This study evaluated the effect of intranasally administered dexmedetomidine (DEX) in combination with local anesthesia (LA) on the relief of stress and the inflammatory response during functional endoscopic sinus surgery (FESS). METHODS Sixty patients undergoin...
