Abstract:
... Granular beds exhibit interesting performances, in terms of ultrafine particle collection efficiency, hot gas cleaning, low cost and robustness. Nevertheless, some authors highlighted that ultrafine particle deposit is essentially located in the first layers of the granular bed. Thus, only a small depth is useful thereby reducing both the operation time between two uncloggings and the process yiel ...

This experimental work focuses on the effect of a swirl flow on whey protein fouling and cleaning in a straight tube, independently of any other factors. In a holding section after a heating zone composed of a plate heat exchanger, the dry deposit m ...

Abstract:
... Delays in cleaning up contaminated “brownfield” sites have led many states to adopt voluntary cleanup programs (VCPs), but the incentives they create remain poorly understood. We present the first theoretical model of VCPs, motivating it from a review of their institutional background, and the limited empirical literature on their effects. We show that tort liability alone leads to excessive devel ...

Abstract:
... Given their high yield of artefacts and ecofacts, cesspits are afforded much time and effort in urban archaeology. While historical sources reveal that cesspits were emptied at regular intervals every few years, archaeologists still treat cesspits as closed contexts where artefacts lie fossilized and undisturbed by subsequent cultural or natural processes. This ‘archaeological blind spot’ results ...

However, some opisthorchiasis patients have no history of eating uncooked fish. We, therefo ...
