BACKGROUND Accurate evaluation of the plain radiography of lower limb is critical for preoperative planning of total knee arthroplasty (TKA). We aimed to investigate the effect of femoral lateral bowing and rotation on the radiographic measurements of distal femoral condyle resection thickness (DRT) and the distal femoral resection valgus angle (FVA). METHODS We analyzed 246 three-dimensional...

We study the effect of stellar rotation on the carbon ignition in a carbonoxygen white dwarf accreting CO-rich matter. Including the effect of the centrifugal force of rotation, we have calculated evolutionary models up to the carbon ignition for various accretion rates. The rotation velocity at the stellar surface is set to be the Keplerian velocity. The angular velocity in the stellar interio...

We are investigating novel techniques to obtain time-dependent magnetic field measurements in wire-array Z-pinches and X-pinches. An ideal method would be emission spectroscopy (Zeeman splitting of lines, for example, in the visible or VUV spectrum), as it would be entirely passive and non-perturbing. However, a spectroscopic method to determine the high magnetic fields present in megampere lev...

We present multi wavelength parsec-scale Faraday rotation measure properties of twenty active galactic nuclei, observed with the Very Long Baseline Array simultaneously at 1.4, 1.6, 2.2, 2.4, 4.6, 5.0, 8.1, 8.4 and 15.4 GHz in the full polarization mode. For the observed sources we construct Faraday rotation measure and Faraday-corrected linear polarization maps. Direction of electrical field i...

During the past 2 yr, we have been theoretically and experimentally investigating coherent backscattering ~CBS! of near-resonant light in a sample of cold rubidium atoms @1–3#. CBS is an interference effect in the multiple scattering regime of propagation inside random media, yielding an enhancement of the backscattered light intensity @4#. This interference is very robust and can be destroyed ...

We report a theoretical study on the effect of mechanical rotation of nanomagnet about a fixed axis due to its interaction with an electromagnetic wave with a frequency approaching that of ferromagnetic resonance. A stationary mode of rotation is investigated. We show that the rotation speed magnitude is proportional to the squared amplitude of the wave’s magnetic field, being maximum for a cir...

We present analysis of the flux and polarization variability of parsec scale radio jets from a dual-frequency, six-epoch, VLBA polarization experiment monitoring 12 blazars. The observations were made at 15 and 22 GHz at bimonthly intervals over 1996. Here we analyze the flux, fractional polarization, and polarization position angle behavior of core regions and jet features, considering both th...

A sample of large northern Spitzer Infrared Nearby Galaxies Survey (SINGS) galaxies has recently been observed with the Westerbork Synthesis Radio Telescope (WSRT). We present observations of the linearly polarized radio continuum emission in this WSRT-SINGS galaxy sample. Of the 28 galaxies treated in this paper, 21 are detected in polarized radio continuum at 18and 22-cm wavelengths. We utili...
