Abstract Density-wave fronts in a vibrofluidized wet granular layer undergoing a gas-liquid-like transition are investigated experimentally.The threshold of jeep liberty fender flare the instability is governed by the amplitude of the vertical vibrations.Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of th

This paper explores the application of boron oxide (B2O3) as a sintering additive in silicon-based (SiO2) ceramics, focusing on its impact on the sintering process and resulting ceramic properties.Composite silicon-based ceramic shells with boron oxide content ranging from 0 to 4 Wt% were prepared using digital light processing (DLP) technology.Thi
This study examines auroral colour camera data from the Canadian Dense Array Imaging SYstem (DAISY).The Dense Array consists of three imagers with different narrow (compared to all-sky view) field-of-view optics.The main scientific motivation arises from an earlier study by Knudsen et al.(2001) who used All-Sky Imager (ASI) combined with even earli
