The mechanical force-induced activation of the adhesive protein von Willebrand factor (VWF), which experiences high hydrodynamic forces, is essential in initiating platelet adhesion. The importance of the mechanical force-induced functional change is manifested in the multimeric VWF's crucial role in blood coagulation, when high fluid shear stress activates plasma VWF (PVWF) multimers to bind p...
Shear wave measurements for the determination of tissue elastic properties have been used in clinical diagnosis and soft tissue assessment. A shear wave propagates as a transverse wave where vibration is perpendicular to the wave propagation direction. Previous transverse shear wave measurements could detect the shear modulus in the lateral region of the force; however, they could not provide t...
This study makes use of the Tsallis entropy to predict the shear stress distribution. Given a definition of the Tsallis entropy, it is maximized by using the probability density function, which then is used to attain a novel shear stress equation. This is then employed for calculating the shear stress distribution in rectangular channels in different aspect ratios and finally, for viability, th...
Background: Today, different types of tapes used for prevention and treatment of chronic inversion ankle sprain. The purpose of current study was to investigate the effect of two different tapes (white and Kinesio tape) on peak knee anterior shear force during landing after the jump among elite volleyball players with chronic inversion ankle sprain. Methods: In this semi- experimental study,...
The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...
Investigations have been performed on the dynamics of a distance regulation system based on an oscillating probe at resonance. This was examined at a tuning fork shear-force feedback system, which is used as a distance control mechanism in near-field scanning optical microscopy. In this form of microscopy, a tapered optical fiber is attached to the tuning fork and scanned over the sample surfac...
background: esthetic demands among patients have led to the introduction of tooth-colored restorations. composite resins bond to enamel applying acid etch technique. total etch adhesion systems are still considered as golden standard among bonding systems. however, clinicians have tendency towards using adhesive systems with a simplified application procedure. the aim of the present study is to...
