The tissue pH UpH) probe first described by Stamm and Janecek 0-5). has been further developed and incorporated into a System intended for clinical use*. The System includes appropriate safety isolated circuitry, automatic calibration and a chart recorder. "Sterile calibratlon buffers and a calibration System are included. A special wide flange spiral electrode is used to apply and hold the pro...

The Hot AXIOS system is a new device for transgastric or transduodenal endoscopic drainage of a pancreatic pseudocyst or the gallbladder [1,2] using a lumen-apposing metal stent (LAMS) mounted on an electrocautery-enhanced introduction system. The device seems to be relatively safe in expert hands; however, the literature on management of its complications is limited [1–4]. Hereby, we report on...

This study aimed to explore the clinical effects of percutaneous kyphoplasty combined with pedicle screw fixation on aged osteoporotic thoracolumbar burst fracture. 160 patients with aged osteoporotic thoracolumbar burst fracture treated at our hospital during January 2012 and January 2015 were enrolled. According to the digital meter method, they were randomly divided into two groups, the obse...

This paper presents a new methodology for complete solution of general shape deep drawn parts. Evaluation of forming severity, estimation of the punch load and prediction of the thickness variation are the major results obtained in this work. The punch work is the summation of the homogenous work of flange deformation and bending and frictional works. To evaluate the strain energy of the flange...

In this research, two new methods that improve the drawing depth of deep-drawing processes have been introduced. In the first technique, by creating ridges on the punch surface, the stress concentration is decreased on the blank near the punch edge, in turn increasing the drawing depth. The second method is based on the principle of reducing resistant force in the flange area between the die, t...

Top and seat beam-to-column connections are commonly designed to transfer gravitational loads of simply supported steel beams. Nevertheless, the flexural resistance characteristics these type should be properly taken into account for design, when a reliable analysis semi-rigid structures is desired. In this research paper, different component-based mechanical models from Eurocode 3 (EC3) litera...

The object of study is a single-stage double-suction axially split volute casing centrifugal pump.
 Background. In the design process pumps, problems associated with ensuring tightness axial joint pump being under effect mechanical and temperature loads, are solved. During tightness, numerical calculation methods used to estimate pressure intensity on contacting surfaces. A detachable exte...
