The artificial hip joints have galvanic couple between femoral head made of CoCr alloy and stem Ti or alloy, are subjected to high levels mechanical stress. Therefore, tribocorrosion has been frequently reported. In this study, we performed the first electrochemical numerical simulation for with friction in simulated body fluid. We constructed single metal model investigate effect cathodic reac...

The ESR spectrum of calcium-deficient hydroxyapatite (DAp) has the peaks assigned to the hyperfine structure of dangling H+ (hyperfine coupling constant = 50.8 mT, I = 1/2) due to the HPO(4)2- ion which captured the hole released by X ray irradiation. This ESR peak intensity in DAp with collagen (c-DAp) decreased in an increase in the amount of collagen added into Ca(H2PO4)2H2O (MCP) electrolyt...

background: advances in radiation dosimetry concepts and the development of primary measurement standards based on absorbed dose to water over the last decades offer the possibility to calibrate ionisation chambers directly in terms of absorbed dose to water. the aim of this study is the investigation on utility of artificial body fluid (abf) instead of water by comparing dosimetric measurement...

The flow field and the motion of the free surface in an oscillating container are simulated numerically to assess the numerical approach for studying two-phase flows under oscillating conditions. Two numerical methods are compared: one is to model the oscillating container directly using the moving grid of the ALE method, and the other is to simulate the effect of container motion using the osc...

A computer algorithm is implemented to construct 3D cubic pore networks that simultaneously honor nuclear magnetic resonance (NMR) and mercury injection capillary pressure (MICP) measurements on core samples. The algorithm uses discretized pore-body size distributions from NMR and pore-throat size vs. incremental pore-volume fraction information from MICP as initial inputs. Both pore-throat rad...

Glow discharge at atmospheric pressure using a dielectric barrier discharge can induce fluid flow, and operate as an actuator in flow control. In the present work, a modeling framework is presented to study the evolution and interaction of such athermal non-equilibrium plasma discharges in conjunction with low Mach number fluid dynamics. Under atmospheric pressure, the discharge can be simulate...
