This paper presents results from stability analysis and testing on high pressure CO2 centrifugal compressors, beginning by a preliminary analysis conducted on an academic institution. It includes results of stability tests that were carried out in manufacturer facilities. The tests were done on two different compressor designs, both operating with high content of CO2 in super critical condition...

We investigate the role of ram pressure stripping in the Virgo cluster using N-body simulations. Radial orbits within the Virgo cluster's gravitational potential are modeled and analyzed with respect to ram pressure stripping. The N-body model consists of 10 000 gas cloud complexes which can have inelastic collisions. Ram pressure is modeled as an additional acceleration on the clouds located a...

A novel stripping chemiluminescence (CL) method in situ has been developed which is a combination of selective stripping and CL detection in situ. This method consists of a concentration (pre-electrolysis) step, in which the analyte metal ion is reduced at a controlled potential whilst being deposited as the metal on a solid electrode placed in an electrogenerated chemiluminescence flow cell, a...

The aim of this study was to compare the results of high ligation and stripping of the great saphenous vein (GSV) trunk combined with foam sclerotherapy with conventional surgery for the treatment of superficial venous varicosities of the lower extremity. One hundred and thirty eight patients with primary or secondary superficial venous varicosities of the lower extremity were included. 60 unde...

INTRODUCTION The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure. METHODS The study included 29 orthodontic patients (mean age, 18.2 ± 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (<15,000 rpm; 10 seconds) on the mandibular anterior te...

The oesophageal vestibule lies at the lower end of the oesophagus immediately above the stomach. Pressure recordings in normal adults indicate that after pharyngeal deglutition the vestibule relaxes. They show that this relaxation occurs shortly after deglutition and that it persists until the oeso-phageal stripping wave reaches the vestibule (Fyke, Code, and Schlegel, 1956). Carrd and Astley (...

BACKGROUND Varicose veins are prominent dilated veins in the lower limb primarily due to disease in the junction between superficial and deep venous system. Operative treatment of such condition significantly improves quality of life and also demonstrably decreases the potential complications. We present with analysis of fifty one consecutive open surgeries for varicose vein at Dhulikhel Hospit...
