Measuring surface crack depth is performed by calibration samples made of the same material like the object being tested. Calibration samples are the plates having narrow grooves like slits of various depth 0.2 mm, 0.5 mm, 1.0 mm, 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm and made by electric erosion method. The samples have dimensions 50 mm X 150 mm x 6 mm and 25 mmx 150 mm x 6 mm and are made of magnetic... 

The protein dimer binds so that the recognition a helices at opposite ends of the protein molecule are in the major groove of the DNA as predicted, where they interact with base pairs at the end of the DNA molecule. Since these binding sites are separated by one turn of the DNA helix, it follows that at the center of the DNA molecule the narrow groove faces the protein... 

For sustained low oil consumption, narrow, deep-groove piston rings conform easily to liner walls. Top compression ring is chrome-plated to condition liners during break-in.

Carefully scrape the separated bromophenol blue spots on to a sheet of clean smooth-surfaced paper using a narrow spatula (this is easier if two grooves are made down to the glass on either side of the spots). Pour the blue powder into a small centrifuge tube, add 2 mL of ethanol, 5 drops of 0.880 ammonia solution, and stir briskly until the dye is completely extracted. Centrifuge and remove the supernatant blue solution from the residual white powder. Repeat this procedure with the separated Congo red and phenol red spots . 

Fig. 12 (A) The d(CGCGAATTCGCG)2 duplex with a narrow groove and a sodium ion coordinated at the ApT step. (I) The DNA is shown in stick representation and the ion in space-filling size. Left view is directly into the central minor groove. Right view left view rotated 90° counterclockwise and tilted 30° to show the ion in the minor groove. (II) The base pair views are of the central ApT step. Top view is down the helix axis, bottom view is directly into the minor groove. (B) The DNA duplex with a phosphate-oxygen pair-sodium ion interaction and a water molecule coordinated at the ApT step. (II) Views as in Fig. 12A for the phosphate-ion-water-base complex at the AT site. Reproduced with permission from Ref. (42). Copyright 2000, American Chemical Society.

Filled hard gelatin capsules are held together by interlocking bumps and grooves molded into the cap and body pieces, and the capsules are usually additionally sealed by a banding process, which places a narrow strip of gelatin around the midsection of the capsule where the two pieces are joined.
