Failure mechanisms of geocell walls and junctions

FAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES

Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...

BPS Walls and Junctions in SUSY Nonlinear Sigma Models

BPS walls and junctions are studied in N = 1 SUSY nonlinear sigma models in four spacetime dimensions. New BPS junction solutions connecting N discrete vacua are found for nonlinear sigma models with several chiral scalar superfields. A nonlinear sigma model with a single chiral scalar superfield is also found which has a moduli space of the topology of S and admits BPS walls and junctions conn...

Numerical Analysis of Geocell Protective Slope Stability

Geocell protective slope is a kind of important ecological protection form, which is widely used in the geotechnical engineering field. Based on the finite element software ABAQUS, and combining with protective slope body’s mechanics performance in shallow soil, the finite element model of geocell slope protection is established under the conditions of rainfall seepage, and then we simulate the...

Mechanisms of Defibrillation Failure

Since defibrillation by high-energy electric shocks is the only effective means for termination of ventricular fibrillation, defibrillation shocks are now widely used in clinical practice for prevention of sudden cardiac death. However, the high-energy shocks could result in myocardial dysfunction and damage (Runsio et al., 1997) and in psychological trauma (Maisel, 2006). Comprehensive underst...
