Close Preview. Focuses on the second-order turbulence-closure model and its applications to engineering problems. Topics include turbulent motion and the averaging process, near-wall turbulence, applications of turbulence models, and turbulent buoyant flows.
For adults, 5 to 7 days is enough. The guidelines recommend treating bacterial sinus infections with amoxicillin-clavulanate, instead of the drug currently used, amoxicillin, because the addition of clavulanate helps to thwart the development of antibiotic resistance.
