SUBDUCTION ZONES and ISLAND ARCS. Subduction Zones are where cool lithospheric plates sink back into the mantle. It takes about 50 my for the ocean lithosphere that formed in the hot (>1000C) environment at mid-ocean ridges to cool to an equilibrium state and sink to its maximum depth below sea-level.
Ebola hemorrhagic fever is a viral disease caused by Ebola virus that results in nonspecific symptoms (see symptom section of this article) early in the disease and often causes internal and external hemorrhage (bleeding) as the disease progresses.
The symptoms of the Ebola thus begin to show up. The period between the Ebola virus entering the body and the symptoms showing up is known as the incubation period. This incubation period of Ebola virus can be as short as 2 days or as long as 21 days.In some cases the symptoms of the Ebola virus can be seen from the fourth or the sixth day itself.or instance For example, the incubation period for Lake Victoria Marburg virusor Zaire Ebola viru s infection in rhesus macaques is between 3 to 16 days; however, for that of guinea pigs it is around 4 to 10 days.
