Bilateral Variability of the Quadriceps Angle (Q angle) in an Adult Indian Population
Objective(s) The objective of this study was to document and explain bilateral differences in the Q angle. Materials and Methods Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with res...
متن کاملAn Archean quartz arenite–andesite association in the eastern Baltic Shield, Russia: implications for assemblage types and shield history
Shallow water sedimentary units are generally considered scarce in Archean greenstone belts. We describe an unusual quartz arenite-subaerial andesite association within the Archean Hisovaara greenstone belt, a fragment of the Parandovo-Tikshozero belt within the Karelian craton of the Baltic Shield. The Hisovaara greenstone belt consists of several lithotectonic assemblages: (1) a komatiite-tho...
متن کاملdetermination of lg coda q from local earthquakes in the central alborz, iran
in the present study, the q factor is obtained for the central alborz in iran using the lg coda method. the energy of a seismic wave decays while passing through a ‘real’ medium such as the earth which is not completely elastic. the decay in energy is due to non-elastic phenomena and is called intrinsic attenuation and is characterized with the q parameter, the large values of which represent s...
متن کاملApplication of the telegraph model to coda Q variations in southern California
[1] We examine waveforms and data used to construct coda magnitude in southern California to estimate the spatial variation of coda Q and its dependence on frequency. Our analysis combined with independent borehole data suggests that coda is mainly generated by multiple scattering in the upper few kilometers of the crust where large impedance contrasts occur because of surface layering or fract...
متن کاملStudy of Duplicated Optic Canals in Eastern Indian Human Skulls
Objective: The duplication of optic canals is a rare anomaly found in both sexes, all ages, and various races. The present study was carried out to find the incidence of duplication of optic canal and to study its clinical and developmental significance. Methods: The study included 100 dry human skulls of both the sexes and various age groups. These skulls were studied grossly and morphological...
