This study explores the potential of magnetic stones on Mount Penanggungan and their relation to history and myths circulating in the community and climbers. This research is important to do in order to minimize the rate of injury caused by fatigue for cl... see more

In the Northern iron-ore district of the Kryvbas basin, mining of deposits of poor magnetic ores is underway in two quarries – Pervomaiskyi and Hannivsky. Oftentimes, their mine contours contain low-valuable or unusable magnetite-silicaceous quarzites of ... see more

Due to its fast and economical execution, the geotechnical solution known as soil nailing walls is widely used for the stabilization of slopes and ground excavations. At the design stage, verification of the external stability of the soil nailing wall is ... see more

This study presents a dynamic model for a concentrating solar energy collector with an integrated rock bed heat storage system. The model is based on numerical integration of a set of conservation equations for mass, momentum and energy of the heat carrie... see more

Numerical simulations are carried out for the internal flow field of a dual pulse solid rocket motor port to understand the flow behaviour. Three dimensional Reynolds Averaged Navier Stokes equations are solved alongwith shear stress transport turbulence ... see more

The shrinkage of swelling rock boreholes in coalmines is a complex problem affected by multiple fields coupling, such as humidity field and stress field. By establishing the equilibrium equation of swelling rock boreholes in coalmines, considering the exp... see more
