Individual differences in cognitive performance increase from early to late adulthood, likely reflecting influences of a multitude of factors.We hypothesize Immune Support System that losses in neurochemical and anatomical brain resources in normal aging modulate the effects of common genetic variations on cognitive functioning.Our hypothesis is ba
One of the most frequently quoted ecosystem services of seagrass meadows is their value for coastal protection.Many studies emphasize the role of above-ground shoots in attenuating waves, enhancing sedimentation and preventing erosion.This raises the question if short-leaved, low density (grazed) seagrass meadows with most of their biomass in below
Abstract Background Filmy-ferns (Hymenophyllaceae) are poikilohydric, homoiochlorophyllous desiccation-tolerant (DT) epiphytes.They can colonize lower and upper canopy environments of humid forest.Filmy-ferns desiccate rapidly (hours), contrasting with DT angiosperms (days/weeks).It has been proposed that desiccation tolerance in filmy-ferns would
Calculating the unsteady convective heat transfer on helicopter blades is the first step in the prediction of ice accretion and the design of ice-protection systems.Simulations using Computational Fluid Dynamics (CFD) successfully model the complex aerodynamics of rotors as well as the heat transfer on blade surfaces, but for a conceptual design, f
