X-ray absorption near edges structure -S) spectra of the Diluted Magnetic Semiconductors @MS) system Zn,&S (M=Mn, CO) have been measured at the M n and CO L,,>-edge using sample current mode. Analysis of the M L3,2-edge XANES spectra for Zn,.&S revealed the presence of a white line feature in each series, whose intensity increased linearly with concentration X. The white line feature is assigne...

A5.2 year-old Holstein cow was presented with lameness andabnormal weight bearing in a slaughterhouse. Widening of theperiople and swelling of the heel area in the lateral claw was morepermanent than the medial claw. Vertical fissure (VF) involvingthe coronary band to the middle of the dorsal wall of the medialhind claw was observed. It was also extended to the bearingsurface in the inner surfa...

A measurement, modelling and identification system is proposed to qualify a subscriber line with the constraint that only measurements can be conducted at the Central Office. The system uses the one-port scattering parameter as a base measurement of the loop. The time domain version of this scattering parameter will be pre-processed so that the features, which are the start, maximum and end pos...

The study of multiracial people in the United States has typically focused on experiences Black–White racially-mixed individuals. In this article, we review and analyze theoretical evidence base for White-leaning characterization Asian–White multiracials. Historically, Asian Americans have been positioned as a “racial middle” group relation to White Black Americans. line with perceived racial p...

The northern Québec-Labrador tree lines are the most climatically stressed tree ecosystems of eastern North America. In particular, white spruce (Picea glauca) tree line populations distributed between 56 degrees N and 58 degrees N and 61 degrees W and 66 degrees W show contrasted responses to recent changes in climate according to their geographic position relative to the Labrador Sea. Along t...

Previous investigations on hydrogen-rich white dwarfs generally yield only very small rotational velocities (vrot · sin i). We have analyzed line profiles in high-resolution optical spectra of eight hydrogen-deficient (pre-) white dwarfs and find deviations from the dominant Stark line broadening in five cases which, interpreted as an effect of stellar rotation, indicate projected rotational ve...

In only three of the 61 known magnetic white dwarfs helium has been identified unambiguously while about 20% of all non-magnetic stars of this class are known to contain He I or He II. One reason for this discrepancy is that the identification of peculiar objects as magnetic white dwarfs is based either on the presence of hydrogen line components in strong magnetic fields — for which atomic dat...
