INFLUENCE OF AERATION INDUCED BY PIERS ON THE STARTING POSITION OF THE FLOW AERATION AND EXTREME PRESSURES IN STEPPED SPILLWAYS

Influence of aeration induced by piers on the starting position of the flow aeration and extreme pressures in stepped spillways

ABSTRACT The operation of stepped spillways is limited by a range of discharges due to the risk of occurrence of Collections the cavitation phenomenon and erosion on its steps.Since there is a demand for spillways with the possibility of overflow of greater discharges, the designs seek to increase the air concentration of the flow, which can occur

25-Hydroxycholesterol and 27-hydroxycholesterol inhibit human rotavirus infection by sequestering viral particles into late endosomes

A novel innate immune strategy, involving specific cholesterol oxidation products as effectors, has begun to reveal connections between cholesterol metabolism and immune response against viral infections.Indeed, 25-hydroxycholesterol (25HC) and 27-hydroxycholesterol (27HC), physiologically produced by enzymatic oxidation of cholesterol, act as inhi
