Example Sentences:

(2) Laboratory tests on compression assemblies demonstrated that: hex-nut loosening can be produced in the laboratory by the cyclical loading of compression assemblies; crimping of the threads of the rod prevented hex-nut back-off and loosening of the SHB; crimping of the threads of the rod with the described rod crimper applied at a 90 degree angle did not damage the core of the rod or compromise its ability to withstand cyclical or tension loads; and crimping of the threads of the rod at angles other than 90 degrees damaged the core of the rod and significantly altered its ability to withstand cyclical loading.

(7) Both pleated septate and gap junctions were found in the immature state; their intramembranous particle (IMP) distribution was characteristic of junctions in the process of assembly, since the IMPs were irregularly and loosely arrayed in contrast with the parallel septate junctional IMP rows and gap junctional plaques found in the fully regenerated or control tissues.
