The study of the acoustic effect of perforated plates by Large-Eddy Simulations is reported. The ability of compressible Large-Eddy Simulations to provide data on the flow around a perforated plate and the associated acoustic damping is demonstrated. In particular, assumptions of existing models of the acoustic effect of perforated plate are assessed thanks to the Large-Eddy Simulations results...

The ingestion of non-steroidal anti-inflammatory drugs (NSAID) in 272 patients with bleeding or perforated peptic ulcer was compared with 272 age/sex matched controls. A significantly higher proportion of patients with gastric ulcers had received NSAID than those with duodenal ulcers. Twelve of 90 (13%) patients admitted with bleeding duodenal ulcers had received NSAID compared with 11 of 26 (4...

The choice of antibiotics would depend on the bacteriology associated with perforated appendix. In a retrospective survey of the bacteriology of peritoneal pus obtained from cases of perforated appendix at the General Hospi...

FOR many years I have used perforated solid glass necklace beads of various sizes for the above purpose. They -were perhaps not so suitable as carbonized bone or gold basket spheres but were much easier to obtain than the former and far cheaper than the latter. Most of the other materials used for implantation have greater or lesser disadvantages; e.g., hollow glass spheres -may burst, smooth u...

OBJECTIVE To examine whether density of providers or health care facility factors have a significant effect on the rates of perforated appendicitis in the pediatric population. DESIGN A retrospective database analysis. Data were linked to the Area Resource File to determine if there was an association between perforated appendicitis and density of provider and facility factors. SETTING The ...

CV. XYZ is a belt-producing MSME located in Surakarta. The problems faced by the unavailability of product variations , or it can be said that these MSMEs do not yet have various differentiations. Coupled with productivity at still bad. workers use manual tools and belts are perforated using nails hammers. Based on problems, this study aims to help determines best investment alternatives order ...
