A system and method for object inspection detects and reports object andor object feature shapes from an acquired image of an inspected sample-object using both edge-based and grey level-based data. More particularly, the invention provides peptide substrates and fusion polypeptide substrates comprising a \u03b2-secretase cleavage site. The polyimide adhesive layer has a Tg>400\xb0 C. The control section has a detector which detects movement of the eject member and a valve drive unit which closes the valve mechanism of the generator section when the movement of the eject member is detected by the detector. The beads absorb a portion of the heavy isotopes from the slurry by exchange with waters of hydration of the beads while the hollow core fiber allows permeation of only light water from said slurry outwardly through the HCF wall as a permeate.
