Natural gas as a clean energy, its extensive use can alleviate energy crisis and environmental pollution other problems. The storage transportation of natural are great significance to the standard gas. Suqiao reservoir is responsible for seasonal peak adjustment emergency supply in Beijing-Tianjin-Hebei region, corrosion tubular goods most important issue. In this paper, tubing composition ana...

The authors report the case of a 66-year-old male patient diagnosed with a pseudoaneurysm of the distal aorto-aortic anastomosis treated with the inner tubing technique. The patient had been operated on 1 year before when he had an aortic prosthesis implanted as treatment for a ruptured abdominal aortic aneurysm. The inner tubing technique was developed to facilitate the treatment in bifurcated...

A physical model of turbulent equipartition (TEP) of plasma angular momentum is developed. We show that using a simple, model insensitive ansatz of conservation of total angular momentum, a TEP pinch of angular momentum can be obtained. We note that this term corresponds to a part of the pinch velocity previously calculated using quasilinear gyrokinetic theory. We observe that the nondiffusive ...

a capillary electrophoresis method was used for assay of some degradation products of carvedilol. the optimized parameters were as; running buffer 80 mm acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kv, temperature is 20 ºc and the wavelength range of 200-350 nm. the results indicate that the proposed ce method could effectively separate carvedilol from its de...

radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in csf (cerebro-spinal-fluid) flow. we present a case of complicated csf shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. the findings were confirmed by surgery performed for correction of the shunt ...

In the past few decades, laparoscopic adjustable gastric banding is one of the most common bariatric procedures performed to treat morbid obesity. Device-related complication such as connection-tubing problem is rare. Here we present a case of gastric band tubing complication during pregnancy. This case illustrates the need to maintain high index of suspicion of gastric band device-related comp...
