An experimental study of a leading-edge alula-inspired device (LEAD) for moderate aspect ratio wings at low Reynolds numbers
… phenomena such as stall and flow separation. Birds mitigate those limitations by adapting their wings and feather shapes during flight. Equipped with a set of small feathers, known as Alula, located near the leading edge and covering 5% to 20% of the span, bird wings can sustain the lift …

Design and aerodynamic analysis of an airfoil with a bioinspired leading edge device for stall mitigation at low Reynolds number operation
… surfaces, such as flaps or slats, from the wing leading or trailing edges are often used to extend the aerodynamic envelope. One such aerodynamic device is the Alula, a feather structure attached to one of the hand digits of a bird's wing. The alula is extended by birds at high incidence …

Population biology and fish hosts of several federally endangered freshwater mussels (Bivalvia: Unionidae) of the upper Tennessee River drainage, Virginia and Tennessee
A freshwater mussel survey was conducted in Indian Creek, Tazewell County, Virginia, during 1996 and 1997. Fifteen species were identified, including the federally endangered <i>Epioblasma florentina walkeri<i>, <i>Villosa perpurpurea</i>, and <i>Quadrula cylindrica strigillata</i>. Population …
