Tracking airborne Legionella and Legionella pneumophila at a biological treatment plant
(2008)
Biological treatment plants are frequently used to degrade organic substances in wastewater from wood refinement processes. Aeration ponds in such plants provide an optimal growth environment for many microorganisms, ...
Assessment of the dispersion of Legionella-containing aerosols from a biological treatment plant
(2011)
Legionella was detected in aeration ponds (biological treatment plant) at Borregaard Ind. Ltd., Norway, and in air samples harvested directly above these ponds. Since 2005, three outbreaks of legionellosis occurred within ...
Flow noise reduction from superhydrophobic surfaces
(2012)
This work investigates how a highly (super)hydrophobic
surface can be used to reduce turbulence-generated drag and
noise on a towed streamer cable. The work is done by analyzing
full-scale drag and flow noise measurements ...
