Piano key (PK) weirs are used in a variety of flow control structure applications, including spillway crests and open channel diversion structures. However, to the best authors’ knowledge, structure-specific design guidance for scour mitigation is still needed. To fill this gap systematic experimental campaign was conducted by testing different configurations horizontal aprons with cutoff wall....

Abstract. Ice aprons (IAs) are part of the critical components Alpine cryosphere. As a result changing climate over past few decades, deglaciation has resulted in surface decrease IAs, which not yet been documented, except for specific examples. In this study, we quantify effects change on IAs since mid-20th century Mont Blanc massif (western European Alps). We then evaluate role meteorological...

This work studied protective material consisting of several metal oxide composites (Pb3O4, WO3, SnO2, and Bi2O3)-natural rubber (NR) for X-ray gamma-ray shielding. The were prepared through open milling vulcanization processes further characterized by scanning electron microscope (SEM), diffraction (XRD), rheometry analysis, density gauge. attenuation coefficient the sample was investigated usi...
