Microscopic analysis underlined the examinations concerning the perforation efficiency (see Fig. 6).
The second issue which we investigate here concerns the perforation of metallic plates by sharp nosed projectiles.
In our experience, the incidence of new perforations was more statistically significant in the Group B patients than in Group A (p = 0.01), but we have not found any data in literature concerning incidence of new perforations.
Postprocedural pain creates concern for perforation and often results in postprocedure admission (PPA).
112 Although it is possible to remove some LNPCPs en bloc with snare resection, it may be technically difficult to achieve owing to reduced snare stiffness while uncertainty about the resection plane may lead to concerns about perforation due to lack of control of tissue volume and from thermal injury due to an inability to control the cutting plane.
Despite the overall tolerability of this last regimen, the four subacute adverse events (ulceration, bleeding, perforation) reported in the radiation field are concerning.
Tape containing perforations for an entire set of type in a given style is inserted into a special Digiset reader to instruct the magnetic memory, in a few dozen seconds, concerning type production.
We highlight various features concerning the effective resisting stress (σr) which a finite thickness plate, with a flow stress of Yt, exerts on the projectile during perforation.
Hence, the former could be used to replace the latter, at least, as far as perforation threshold was concerned.
Conversely, air which persists or increases should raise concern for visceral perforation.
I pointed out my medical history of migrating implanted medical devices and my concerns about uterine perforation given my collagen disorder; they shrugged their shoulders.
