BACKGROUND The effect of elbow medial ulnar collateral ligament injury on posteromedial compartment contact is unknown. HYPOTHESIS Medial ulnar collateral ligament injury causes altered contact area and pressure in the posteromedial compartment of the elbow. STUDY DESIGN Controlled laboratory study. METHODS Seven elbow cadaveric specimens were tested in an apparatus that positioned the el...

Abstract. Erosion corrosion is a common problem that affects boiler tubes, particularly those in power plants and industrial settings where hard water abrasive particles are present the flow. These can cause physical erosion to surface of which then lead further corrosion. This type often accelerated by high temperatures pressures system, as well presence oxygen. The combination chemical attack...

bendway weirs are an important tool in multi-purpose erosion control and are implemented to control erosion, restore streams, and improve habitat. these structures create a hydraulic effect that reduces erosion on the outer bank of a bend by reducing flow velocities near the outer bank and reduce the concentration of currents on the outer bank creating better current alignment through the bend....

OBJECTIVE Our aim was to determine the ideal position of upper extremities during ultrasonography guidance for axillary block. The position that provides the shortest distance between the median and musculocutaneous nerves was assumed to be the most appropriate position for axillary block. METHODS In this cross-sectional study, 120 (45 female and 75 male) patients were placed in a position wi...

Skeletal muscle is the largest tissue structure in our body and plays an essential role for producing motion through integrated action with bones, tendons, ligaments and joints, for stabilizing body position, for generation of heat through cell respiration and for blood glucose disposal. A key function of skeletal muscle is force generation. Non-invasive and selective measurement of muscle cont...
