BACKGROUND Medialization and anteromedialization of the tibial tubercle are used to correct patellar subluxation in adults. PURPOSE To compare the effects of the 2 osteotomies on patellofemoral joint contact pressures and kinematics. STUDY DESIGN Controlled laboratory study. METHODS Tibial tubercle osteotomies were performed on 10 cadaveric human knees. The knees were tested between 0 deg...

We show that the structure factor S(q) of water can be obtained from x-ray synchrotron experiments at grazing angle of incidence (in reflection mode) by using a liquid surface diffractometer. The corrections used to obtain S(q) self-consistently are described. Applying these corrections to scans at different incident beam angles (above the critical angle) collapses the measured intensities into...

The stability and natural convection heat transfer characteristics of TiO2-water nanofluid in enclosures with different rotation angles (α = -45°, α = 0°, α = 45°, and α = 90°) are experimentally investigated. The effects of different pH values and doses (m) of dispersant agent on the stability of TiO2-water nanofluid are investigated. It is found that TiO2-water nanofluid with m = 6 wt% and pH...

For three points u, v and w in the n-dimensional space IFq over the finite field IFq of q elements we give a natural interpretation of an acute angle triangle defined by this points. We obtain an upper bound on the size of a set Z such that all triples of distinct points u,v,w ∈ Z define acute angle triangles. A similar question in the real space Rn dates back to P. Erdős and has been studied b...

In the title compound, C(11)H(12)ClN(5)O, the triazolone and pyrimidine rings are almost coplanar [dihedral angle = 2.98 (14)°]. The total puckering amplitude Q(T) of the seven-membered lactam ring is 0.706 (3) Å.

In this paper, we have systematically discussed the existence of spherically symmetric wormhole solutions in framework $f(Q,\,T)$ gravity under two interesting non-commutative geometries such as Gaussian and Lorentzian distributions string theory. Also, to find solutions, consider models linear $f(Q,\,T)=\alpha\,Q+\beta\,T$ non-linear $f(Q,\,T)=Q+\lambda\,Q^2+\eta\,T$ our study. We obtained ana...
