Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate ligament (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quanti...

Nuclear magnetic relaxation ( N M R ) in a gas of regular (tetrahedral and octahedral) molecules f rom the point of view of the kinetic theory of transport and relaxation processes based on the Waldmann-Snider equation is considered. A simple expression is obtained for the spin-rotation interaction based on considerations of the molecular symmetry. The form of the spin-rotation coupling which c...

theoretically, in order to describe the behavior of a spectrum, a mathematical model whichcould predict the spectrum characteristics is needed. since in this study a two-state system has beenused like models which was introduced previously past and could couple with the environment, theformer ideas have been extended in this study. we use the second quantized version for writing thishamiltonian...

We investigate the effect of electron-rotation coupling ($\mathbf{R}\ensuremath{-}\mathrm{\ensuremath{\Omega}}$ coupling) on fs UV photodissociation dynamics aligned diatomic molecules. consider showcase ground-state $\mathrm{Mg}{\mathrm{H}}^{+}$ (${}^{1}{\mathrm{\ensuremath{\Sigma}}}^{+}$) pumped by an IR pulse, which initiates rotational leading to field-free molecular alignment. A time-delay...

The machining precision in the scroll compressor with the compliant crank mechanism is not required so high as that with the fixed throw crank, but the sealing performance is better than the later's, therefore the scroll compressor with the compliant crank mechanism operates at higher efficiency. In this study, the characters of the compliant crank mechanism are discussed, while the Oldham coup...
