lin apparatus ,·,hieh could produce known amounts of angular momenlum in a pipeline was verified by direct measurement of axial and tangential velocity profiles. By using the assumption that a vortimetcr, with vanes spanning only the rotational core, responded to an equivalent solid rotational core, an expression was develop­ ed relating the angular velocity to the angular momentum. Comparison ...

[Purpose] The purpose of this study was to determine the effects of core stabilization exercise on dynamic balance and gait function in stroke patients. [Subjects] The subjects were 16 stroke patients, who were randomly divided into two groups: a core stabilization exercise group of eight subjects and control group of eight subjects. [Methods] Subjects in both groups received general training f...

Whole-core measurements of Wet Bulk Density (WBD), compressional (P)-wave velocity (Vp), and Magnetic Susceptibility were measured at a sampling interval of 1 or 2 centimetres (cm) throughout the AND-2A drill core for initial core characterisation and on-site correlation with seismic modeling to predict target-reflector depth. Measurements were made using a GEOTEK (Multi-Sensor-Core-Logger MSCL...

We propose a new neutrino propulsion mechanism for neutron stars which can lead to strong velocity kicks, needed to explain the observed bimodal velocity distribution of pulsars. The spatial asymmetry in the neutrino emission is naturally provided by a stellar core containing spin-1 color-superconducting quark matter in the A phase. The neutrino propulsion mechanism switches on when the stellar...

In handball, throwing velocity is considered to be one of the essential factors in achieving the ultimate aim of scoring a goal. The objective of the present study was to analyze the effect of a core training program on throwing velocity in 30 handball players (age 18.7 ± 3.4 years, body height 179.3 ± 7.0 cm, body mass 78.9 ± 7.7 kg), 16 of whom were in the junior category and 14 of whom were ...

[1] We constrain seismic velocity structure in the Earth’s outer core by analyzing differential travel times, waveforms, and amplitude ratios of several pairs of core phases. We use differential travel times and waveforms of PKPbc-PKIKP at 144 –148 , PKiKP-PKIKP at 120 –141 , PKiKP-PKPBdiff at the PKP caustics distance range (141 –145 ), and differential travel times and amplitude ratios of PKP...

[1] Seismic phases diffracted around Earth’s core contain information about lowermost mantle wave speeds. By measuring the slowness of incident diffracted energy from array recordings, seismic velocity along the diffracted path can be estimated. Here we apply this principle to diffraction of the major arc seismic phase PKKPab recorded at the Canadian Yellowknife array to estimate P wave velocit...

Velocity-velocity and velocity-intensity phase relations from radiative-hydrodynamics calculations by Carlsson & Stein (1992, 1994) are compared with spatially resolved internetwork observations of the H, K, 8498 A, 8542 A and 8662 A lines of ionized calcium. Several of the computed phase relations agree with observations even though the simulations are dominated by propagating shock waves and ...

A model for the pair-distribution function of nonequilibrium hard-core fluids is proposed based on a model for the effect of velocity correlations on the structure. Good agreement is found with molecular dynamics simulations of granular fluids and of sheared elastic hard spheres. It is argued that the incorporation of velocity correlations are crucial to correctly modeling atomic scale structur...

We constrain seismic properties of the inner core using various body wave observations. In the epicentral distance range of 10−70 o , our high quality measurements of the amplitude ratio of PKiKP and PcP provide a new estimate of the density contrast (0.6-0.9 g/cm 3) at the Inner Core Boundary (ICB). This estimate is compatible with a recent reevaluation of normal mode data, and thus reconciles...
