Identification and analysis of damaged or porous hair [PDF]
Drug Testing and Analysis, 2014 Cosmetic hair treatments have been referred to as ‘the pitfall’ of hair analysis. However, most cosmetic treatments, when applied to the hair as instructed by the product vendors, do not interfere with analysis, provided such treatments can be identified by the laboratory and the samples analyzed and reported appropriately for the condition of the hair.

Interferometric Techniques in Structural Damage Identification [PDF]
Shock and Vibration, 2012 This paper describes several interferometric techniques and their applications in structural damage identification. With that objective in mind, damaged aluminum beams with clamped-free and free-free boundary conditions are analyzed. Different damages cases are inflicted by creating small cuts perpendicular to the beams longitudinal axis, being the ...
