The internal turbulence spectrum of the main stream penetrating the inlet remained the same as that of the oncoming flow, but the spectra of other components were produced by the internal turbulence, whose eddy size was determined explicitly by the size of the model.
For instance, hog waste stored in onsite lagoons can spill into streams or penetrate into groundwater, he says.
Exiting the nozzle at about 200 meters per second, the stream penetrates skin and tissue.
They are thus ineffective against late stage infection when, after an initial blood stream stage, parasites penetrate the central nervous system (CNS) giving rise to the classical symptoms of HAT.
HAT, a fatal disease unless treated, is caused by the protozoan parasites Trypanosoma brucei gambiense and T. b. rhodesiense, which initially reside within the blood stream and then subsequently penetrate into the central nervous system giving rise to the classical symptoms of HAT.
As Minckley and others [ 16] note, fish species that commonly penetrate into headwater streams often have representative populations across drainage divides presumably by finding connections, even if they occur infrequently, and are further isolated over longer time periods by the elevation of land.
At Richard-Toll a large area is irrigated by means of a dam across the Taoué (Taouey), a tributary stream up which Sénégal floods penetrate to Lake Guier.
These results indicate that cancer cells may switch into a more stem-like status when meeting with hypoxic stress, and develop more aggressive phenotype in a manner of selection in a suddenly higher oxygen environment, such as when tumor cells penetrate into blood stream or when the "dormant" metastatic solid tumor cells are mobilized out of bone marrow by till now un-clarified mechanisms.
For example, some IEDs have shaped-charge warheads that upon detonation create streams of molten metal that can penetrate armour.
We were unable to obtain access to an up-gradient surface water sampling location situated within the same stream system because a) we could not penetrate dense and deep thickets that completely surrounded the stream (on accessible property) without making major modifications to existing vegetation; or b) we were not allowed access to personal property farther upstream.
