Introduction Arterial arches of hand are the major blood supply to the structures in the hand. The two arches, superficial and deep palmar arches make an important anastomose between the radial and ulnar arteries. Superficial palmar arch (SPA) is formed by direct continuation of ulnar artery, i.e. superficial palmar branch, completed on lateral side by one of the three branches of radial artery...

Use of affordable and simple tools for screening chronic obstructive pulmonary disease (COPD) is limited. In recent years, measurement forced expiratory volume in the 6 s (FEV6) has been researched as a substitute to replace vital capacity measurements. This work was performed analyze effectiveness simplified handheld flowmeter device search an optimal cutoff value FEV1/FEV6 detect airflow narr...

• Phasic coronary inflow and its determinants have been studied by means of differential pressure, 1 a constant pressure flow-meter, 2 an orifice meter, 8 a cannulating type of electromagnetic flowmeter, 4 and a differential transformer. 15 All are cumbersome and require the use of anesthetics, surgical trauma , anticoagulants, and insertion of the device into the coronary artery of the open an...

Weld shapes significantly impact nozzle safety, and a number of accidents have occurred due to cracking. In order improve weld safety reveal the effect shape on temperature field flowmeters, this study established four types welds, with ten different shapes. Through numerical calculation, in solid domain was systematically studied when flowmeter passed through high-temperature gas. The results ...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...
