Abstract: Dry friction backward whirl is a self-excited vibration state in rotor-to-stator contact systems, by which the rotor is in continuous contact with the stator, slipping continuously on the contact ...

Abstract: Dry whip is an instability of rotor-to-stator contact systems and may lead to a catastrophic failure of rotating machinery. The physical reason for the onset of dry whip in rotor/stator systems ...

Abstract: Lime is one of the main raw materials necessary for the production of autoclaved aerated concrete (AAC). The preparation of lime by calcining limestone directly and indirectly emits a large amount of CO2 due to the limestone ...

Abstract: The prediction models of penetration resistances of spudcan footings on sand overlying clay have been established by extensive centrifuge tests and large-deformation numerical simulations. However, most existing models ...

Abstract: Nanopore-rich high porosity aerated cement (NHPAC) was prepared by introducing nanomontmorillonite slurry (NMS) into aerated cement paste, and the rheology of slurry, pore structure (air voids and microscopic pores), ...

Abstract: Biostimulated microbially induced carbonate precipitation (MICP) is an innovative soil improvement approach utilizing indigenous ureolytic microbes to hydrolyze urea. The objective of this study is to investigate the effect ...

Abstract: Biostimulation through the enrichment of indigenous ureolytic bacteria has been proven to be a feasible approach for implementing microbially induced carbonate precipitation (MICP). To apply this method to real-world ...
