Since the late 1970’s there have been enormous changes in the methods, techniques and applications of neutron activation analysis. Having been a research scientist at the National Research Council of Canada and the McMaster Nuclear Reactor, as well as a professor for ten years at the University of Illinois and 15 years at the University of Texas, I have a unique perspective on the research perf...

The metabolism of halothane during and after anaesthesia was studied in eight patients of different age and body weight by estimating the concentration of halothane and one of its metabolites (bromide) in the blood. A gas chromatograph with an electron capture detector was used to estimate halothane, while blood bromide levels were measured by neutron activation analysis. There was an initial b...

More than 30 mineral elements have been found with different key functions in helping plants and animals to survive and live healthy. As a direct result, they have always attracted the attention of scientists. The quest is to find some efficient analytical and quantitative procedures in this study to determine some mineral and trace elements of Iranian Crocus sativus L. corms. Several studies h...

The use of CCDs in future linear collider experiments will require immunity to large neutron fluences, in excess of /year. The effects on charge transfer efficiency of neutron induced bulk damage are presented along with a demonstration of a technique to fill the traps with sacrificial charge. Operation is then possible at fluences in excess of .

Neutron diffraction in Fe(Al) reveals incommensurate spin density waves (SDWs) in alloys known to be spin glasses. The wave vectors for crystals of Fe(34Al), Fe(40Al), and Fe(43Al) show n varying from 11 to 6 for q-->=2pi(h+/-1/n,k+/-1/n,l+/-1/n)/a(0), where (h,k,l) and a(0) characterize the parent bcc lattice of the CsCl structure. The magnetic reflections are present far above the spin-glass ...
