Three methods of predicting whether an unknown biological specimen of a missing person originates from a member of a particular family comprise an initial automated decision support algorithm for determining a list of relatives of the missing person for DNA typing and which typing technologies of available technologies to use for a listed relative. A frame member connects the rear head tube to the front head tube. A first profile of each vane varies along an axial direction. The power management unit may use the final and the first value to determine the actual residency time. A retention slot is disposed on a wall of the cavity and an attachment element protrudes adjacent to the flange to frictionally engaging the retention slot.
