Central-to-peripheral amplification of the pressure pulse leads to discrepancies between central and brachial blood pressures. This amplification depends on an individual's hemodynamic and (patho)physiological characteristics. The aim of this study was to assess the magnitude and correlates of central-to-peripheral amplification in the upper limb in a healthy, middle-aged population (the Asklep...
BACKGROUND The combination of an elbow dislocation, a radial head fracture, and a coronoid process fracture is known as "terrible triad" injury of the elbow. This injury is one of the most challenging injuries of the musculoskeletal system and almost always causes instability of the elbow. The use of an adjuvant hinged external fixator in such injuries is still debated. CASE PRESENTATION In t...
The present study aims at investigating stress and deformation behavior of rotating thick truncated conical shells subjected to variable internal pressure. Material prpperties of the shells are graded along the axial direction by Mori-tanaka scheme, which is achieved by elemental gradation of the properties.Governing equations are derived using principle of stsionary total potential (PSTP) and ...
The functional formula of the flow coefficients for the radial clearance in a rolling piston rotary compressor was developed by the experiments and Computational Fluid Dynamics (CFD) to improve the accuracy of a compressor simulation program. The experiments and CFD simulation were conducted to obtain the flow coefficients at the radial clearance under the assumptions of incompressible flow and...
New solutions for static non-rotating thin disks of finite radius with nonzero radial stress are studied. A method to introduce either radial pressure or radial tension is presented. The method is based on the use of conformal transformations. PACS numbers: 04.20.Jb, 98.62.Hr, 02.30.Em
OBJECTIVE The aim of this study was to analyse the arterial wall mechanics and the vasoreactive properties of the radial artery in comparison with those of the internal mammary artery and to discuss their implications for coronary bypass grafts. METHODS Measurements of pressure and diameter were obtained from cylindrical segments, whereas measurements of reactivity were obtained from ring seg...
