The authors analysed almost 260 000 measurement points from surveys of radiofrequency (RF) field strengths near radio base stations in seven African countries over two time frames from 2001 to 2003 and 2006 to 2012. The results of the national surveys were compared, chronological trends investigated and potential exposures compared by technology and with frequency modulation (FM) radio. The key...

Ever since the turn of the century the incidence and severity of acutf rheumatism have been steadily falling. In 1889 Cheadle stated that acutf rheumatism was the commonest cause for admission to hospital and was als? frequently seen in private practice. A similar state of affairs is revealed by ̂ figures for admission to one ward at the Bristol Children's Hospital in charge of Dr. Edgeworth who...

An analysis is presented of a model for CP violation duc to Kobayashi and IVaskawa, which has six quarks and purely left-handed currents. The model can reproduce approximately results of the Glashow, lliopotilos and Maiani four-quark model in CP con..erving processes. It gives a close approximation to superweak predictions for 6"1' violation in common K decays, whatever the masses of the fifth ...
