Data from the Sudbury Neutrino Observatory have been used to constrain the lifetime for nucleon decay to ``invisible'' modes, such as n -> 3 nu. The analysis was based on a search for gamma-rays from the de-excitation of the residual nucleus that wou

The technique used at the Sudbury Neutrino Observatory (SNO) to measure the concentration of 222 Rn in water is described. Water from the SNO detector is passed through a vacuum degasser (in the light water system) or a membrane contact degasser (in

A review of evidence in support of a role for 5-HT in the perception of tinnitus

Autor: W.E. Davies, J J Simpson

Publikováno v: Hearing Research. 145:1-7

Tinnitus is a debilitating condition from which some 0.5-1% of the population of the Western world suffer sufficiently badly as to interfere with their normal working and leisure life. There is no satisfactory treatment at the present time and the un

We have carried out a comprehensive ESR and U-series dating study on the Lake Mungo 3 (LM3) human skeleton. The isotopic Th/U and Pa/U ratios indicate that some minor uranium mobilization may have occurred in the past. Taking such effects into accoun

Non-destructive gamma spectrometric U-series dating

Autor: J. J. Simpson, Rainer Grün

Publikováno v: Quaternary Science Reviews. 17:1009-1022

Prehistoric hominid fossils are too valuable to be dated by destructive or even partially destructive methods. Non-destructive U-series dating by γ-ray counting can therefore be a valuable method if relatively large hominid fragments, such as skulls
