Upper age limit for bronchiolitis: 12 months or 6 months?

confidence in their ability to quit experiencing a reduction in their level of motivation, and smokers achieving success boosting them up. We could not establish with confidence whether motivation levels were still balanced between groups throughout the duration of the study. Lastly, it was suggested to expand upon the correlation between behavioural (i.e. GN-SBQ) and physical (i.e. the Fagerst...

Upper age limit should be raised for cancer screening

Caroline White, London 204, 64, 207, 105 Current age bands for cancer screening in the United Kingdom seem to have been arbitrarily selected and are not based on rational criteria, according to researchers from the Wolfson Institute of Preventive Medicine in London. The age band is critical to evaluating the effectiveness of screening programmes and for identifying priorities in screening polic...

Upper Miocene Primates from Kenya

Institute of Animal Genetics, Edinburgh Two symposia on theoretical biology were held in 1966 and 1967 at the instigation of the International Union of Biological Sciences. The meetings were organized by Professor Waddington, and in this article he outlines some of the points discussed at the meetings. The essays arising from the first symposium have recently been published under the title Towa...

Dating sediment burial with in situ-produced cosmogenic nuclides: theory, techniques, and limitations

Dating sediment burial over million-year time scales is crucial in many areas of the Earth sciences and archeology, but is often difficult using traditional techniques. Sediment burial can be dated by the radioactive decay of cosmogenic nuclides, provided that the sediment was exposed to cosmic rays prior to burial. Dating calculations are straightforward if sediment is buried deeply and rapidl...
