Macro stress tests and crises: what can we learn? 1 Few, if any, of the macro stress tests undertaken before the current crisis uncovered significant vulnerabilities. This article examines the reasons for the poor performance by comparing the outcomes of simple stress tests with actual events for a large sample of historical banking crises. The results(More)
Consolidation of clay particles in aqueous tailings suspensions is a major obstacle to effective management of oil sands tailings ponds in northern Alberta, Canada. We have observed that microorganisms indigenous to the tailings ponds accelerate consolidation of mature fine tailings (MFT) during active metabolism by using two biogeochemical pathways. In(More)
Dispersed clay particles in mine tailings and soft sediments remain suspended for decades, hindering consolidation and challenging effective management of these aqueous slurries. Current geotechnical engineering models of self-weight consolidation of tailings do not consider microbial contribution to sediment behavior, however, here we show that(More)
