Transitional-turbulent spots and turbulent-turbulent spots in boundary layers.
Two observations drawn from a thoroughly validated direct numerical simulation of the canonical spatially developing, zero-pressure gradient, smooth, flat-plate boundary layer are presented here. The first is that, for bypass transition in the narrow sense defined herein, we found that the transitional-turbulent spot inception mechanism is analogous to the secondary instability of boundary-laye...
متن کاملIntegrating Sustainable Hunting in Biodiversity Protection in Central Africa: Hot Spots, Weak Spots, and Strong Spots
Wild animals are a primary source of protein (bushmeat) for people living in or near tropical forests. Ideally, the effect of bushmeat harvests should be monitored closely by making regular estimates of offtake rate and size of stock available for exploitation. However, in practice, this is possible in very few situations because it requires both of these aspects to be readily measurable, and e...

Fas (CD95, APO-1, TNFRSF6) is a TNF receptor superfamily member that directly triggers apoptosis and contributes to the maintenance of lymphocyte homeostasis and prevention of autoimmunity. Although FADD and caspase-8 have been identified as key intracellular mediators of Fas signaling, it is not clear how recruitment of these proteins to the Fas death domain leads to activation of caspase-8 in...
متن کاملOn anode spots, double layers and plasma contactors
Luminous, sharply defined and nearly spherical objects (‘fireballs’), typically several centimetres in diameter, have been observed in Ar, Kr and Xe plasmas. The ‘fireballs’ are anchored on a disk anode biased et 4040 V above ground potential. They have been analysed in terms of a spherical double-layer model, in which ionizalion of the gas atoms by electrons energized at the double layer plays...
متن کاملPediatric Spots
This 320 pages book is a great tool to teach the most common pediatrics problems. It includes 21 chapters that cover the most important fields of pediatrics with a good emphasis on growth and development, as well as fluids and electrolytes. The tables on developmental milestones according to chronological age help in memorizing those milestones and in teaching young pediatricians how to practic...
