Asbestosis : Interstitial fibrosis of the pulmonary parenchymal tissue in which asbestos bodies ( fibers coated with protein and iron ) or uncoated fibers can be detected ( American Thoracic Society 1986 ) . However , even though these tests used only the remaining portions of the hair samples , GC / MS detected cocaine in all nine specimens , indicating RlAH 's potential to identify individuals who may be drug users but who probably have not taken drugs within a day or two of a urine test . Complex design bugs that can be detected earlier in the design flow , such as clock synchronization issues , are not getting caught until production . Note : new mail is detected by comparing the last modification time to the last access time . Because hydrate dissociation is a strongly endothermic process , cold spots thus detected should permit us to quickly identify portions of the core containing both massive and disseminated hydrate .
