Background: Proper rotation of components in total knee arthroplasty (TKA) will largely affect the postoperative outcome. Ethnical variation may affect rotational profile. We aimed to evaluate distal femur rotation in Iranian population using transepicondylar axes.   Methods : From a total of 450 knee CT scans and via consecutive sampling, 150 qualified subjects with normal lower extremities ...

We demonstrate that the population of the molecular rotational state through a stimulated impulsive Raman excitation can be controlled by tailoring the femtosecond laser pulse with a V-style phase modulation. The results show that, by precisely manipulating the modulation parameters, both the odd and even populations of the molecular rotational state can be completely suppressed or reconstructe...

BACKGROUND Rotational alignment of the tibial component is important for long-term success of total knee arthroplasty (TKA). This study aimed to compare five axes in normal and osteoarthritic (OA) knees to determine a reliable landmark for tibial rotational alignment in TKA. METHODS One hundred twenty patients with OA knees and 40 with normal knees were included. The angle between a line perp...

Damping of collective rotational motion in A ∼ 190 and A ∼ 150 superdeformed nuclei is studied by means of the cranked shell model with two-body residual force. Numerical calculations predict that in a typical A ∼ 190 superdeformed nucleus, Hg, the rotational damping width is significantly small, Γrot ∼ 30 keV, and that the number of superdeformed bands in the off-yrast region amounts up to 150...

Vibrationally state-resolved differential cross sections DCS and product rotational distributions have been measured for the Cl HD(v 1, J 1)→HCl DCl D H reaction at a mean collision energy of 0.065 eV using a photoinitiated reaction ‘‘photoloc’’ technique. The effect of HD reagent rotational alignment in the Cl HD(v 1, J 2) reaction has also been investigated. The experimental results have been...

We present the implementation of a new crossed-molecular beam, velocity-map ion-imaging apparatus, optimized for collisions of electronically excited molecules. We have applied this apparatus to rotational energy transfer in NO(A(2)Σ(+), v = 0, N = 0, j = 0.5) + Ar collisions, at an average energy of 525 cm(-1). We report differential cross sections for scattering into NO(A(2)Σ(+), v = 0, N' = ...
