THE IMPORTANCE OF SEISMIC PROTECTION OF STRATEGIC OBJECTIVES, IN THE AREA OF INFLUENCE OF USEFUL ROCK QUARRIES, IN WHICH BLASTING WORKS ARE CARRIED OUT

In this scientific article was studied the main methods for assessing the seismic effect generated during the blasting operations with explosives, from quarries on essential infrastructure elements, in the analyzed situation - railway Ski Boots tunnel and supporting pillars of the railway superstructure in the adjacent area of the quarry, regarding

Traditional materials or advanced artificially engineered metamaterials are incapable of effectively addressing the simultaneous challenges of impact energy hazards and low-frequency noise.There is an urgent need for multifunctional materials that can address this multi-physics field coupling problem.Herein, a hierarchical multifunctional chiral me

People’s demand for high-traffic applications and the need for Internet of Things (IoT) are enormous in smart cities.The amount of data generated by virtual reality, high-definition video, and other IoT applications General is growing at an exponential rate that far exceeds our expectations, and the types of data are becoming more diverse.It

Background and aim : The anatomical variations of fissures and lobes of lungs have been described Grinder by many research workers on CT scans, whereas, there were fewer studies done on gross anatomical specimens.Materials and methods : In the present study, 30 embalmed cadavers have been dissected and lungs were examined for fissures and lobes.Res
