Voorbeelden van perforation

• Perforation or damage to adjunct structures is also unlikely, and did not occur during our existing experience.

• Off the perforation centreline, however, the boundary layer profiles are highly distorted.

• The perforations consisted of eight 1 in. holes randomly arranged.

• The samples obtained were studied histologically and the lungs examined with 1 cm serial sections for evidence of serious hemorrhage, contusion or pleural perforation.

• The exploration and empirical quantification of light levels for at least three threshold conditions was performed by adjusting the perforation.

• Numerous small perforations occurred posteriorly but fewer anteriorly.

• We then examine the absorptive properties of this arrangement when the perforations are circular apertures.

• Three 1-cm2 perforations were made on each side of the litterbags to allow macro-fauna to enter.
