| Shorter pili, usually referred to as fimbriae, are a structurally distinct group of extrusions which operate mostly in bacterial attachment to substrate or to other cells. |
| Aluminum extrusions also enjoy wide use as frames for doors and windows and in storefronts. |
| After creating the dies to extrude the frame profiles, workers in Italy produced the extrusions. |
| They were completely blown apart, and all-new spar extrusions and new ribs were built by Ken Hake in Kansas and shipped to New Zealand. |
| Latter group of three ships, built in 1964, used 100 tons of welded 5086 plates and extrusions for the topside structure. |
| Extremely careful metallography on tapered sections through the surface of the specimen has shown that fatigue cracks initiate at intrusions and extrusions. |
