magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
Several lamellar gratings of 18-in. aperture, with 300 diffraction elements per inch, have been made for determining stellar spectra with wide angle telescopes. Central orders are missing at lambda4800, and weak at adjacent wavelengths. The two, equal first orders are about l(m) weaker than spectra by a prism or echelette grating. Dispersion is linear. The procedure of manufacture is adaptable ...
Ethics series, we offer this POINT/COUNTERPOINT Debate and frame it with the following vignette: At Grand Rounds regarding end-of-life issues, a visiting professor offered that when cardiopulmonary resuscitation (CPR) is unlikely to promote survival with a reasonable quality of life, he shares his assessment with the patient. If the patient does not object, he enters a “no CPR” order in the pat...
The detrimental influence of oxygen on the performance and reliability of V/III nitride based devices is well known. However, the influence of oxygen on the nature of the incorporation of other co-dopants, such as rare earth ions, has been largely overlooked in GaN. Here, we report the first comprehensive study of the critical role that oxygen has on Eu in GaN, as well as atomic scale observati...
Human rights and health care under apartheid in South Africa were studied. Human rights violations, such as detention without charge or trial, assault and torture in police custody, and restriction orders, have had devastating effects on the health of persons experiencing them. These violations have occurred in the context of a deliberate policy of discriminatory health care favoring the white ...
