Nekrotisierende Enterokolitis und Fokale Intestinale Perforation
… Enterokolitis (NEK) und die Fokale Intestinale Perforation (FIP) sind schwere Erkrankungen, die in den ersten Lebenswochen von Frühgeborenen auftreten können und durch den Grad der Unreife (niedriges Gestationsalter und Geburtsgewicht) gefördert werden. Als weitere Einflussfaktoren werden …

Characterization of cardiac lead perforation risk via a dynamic simulated environment
Delayed cardiac perforation is a serious medical condition where an implanted cardiac lead migrates through the heart wall, causing life-threatening complications. Where acute perforation occurs during implant, delayed perforation is not detected until after 30 days from implant and is frequently …

Exploring the effectiveness of loop perforation for quality of service profiling
… Our quality of service profiler uses loop perforation, which transforms loops to perform fewer iterations than the original loop, to obtain implementations that occupy different points in the performance/quality of service trade-off space. The rationale is that optimizable computations …

Elastic buckling solutions for thin-walled metal columns with perforation patterns
… of finite element rack-type columns with perforation patterns. The influence of perforations is accounted by reduced thicknesses related to the plate buckling coefficient and transverse web rotational stiffness in the prediction of local and distortional buckling respectively. Global …

Resistance of Carbon Fibre Reinforced Composites to Quasi-static and Ballistic Perforation
The failure mechanisms, as well as the indentation and penetration resistance, of carbon fibre reinforced plastic (CFRP) cross-ply laminates were investigated under quasi-static and ballistic loading. In this thesis, the two most prominent failure modes were indirect tension and shear plugging. To …

IDENTIFICATION OF RISK OF MAXILLARY SINUS PERFORATION IN ASSOCIATION WITH THE SINUS ANGLE
… for lateral wall sinus augmentation technique is perforation of the maxillary sinus schneiderian membrane. Various risk factors such as smoking, sinusitis, sinus septa, sinus pathology, schneiderian membrane thickness, angle of sinus, etc. may lead to increased prevalence. Purpose: This study aims …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… have been developed to examine the effect of perforation diameter and CO2 bubble size distribution on the viscosity and recovery of heavy oil during Enhanced Oil Recovery process. To conduct the investigation, an experimental rig was constructed to simulate the flow of CO2 in heavy oil. The …

Study of surface cracks in a simulated solid rocket propellant grain with an internal star perforation
Solid propellant research has mainly been directed towards more accurate characterization of the propellant material nature and more reliable structural analysis of the grain. Internal star grain design is among the most popular grain shapes that are used in today's propulsion system. Due to its …

Prospective cohort study on thirty day outcome of perforation peritonitis at the University Teaching Hospitals, Lusaka, Zambia
Perforation peritonitis is a common surgical emergency seen by surgeons; it remains a life threatening condition with high morbidity and mortality. At the University Teaching Hospitals (UTH), the morbidity for gastro-duodenal perforation has not been studied. Furthermore, based on the available …
