We investigated the effects of a warmer climate, and seasonal trends, on the fate of oil spilled in the Arctic. Three well blowout scenarios, two shipping accidents and a pipeline rupture were considered. We used ensembles of numerical simulations, using the OSCAR oil spill model, with environmental data for the periods 2009-2012 and 2050-2053 (representing a warmer future) as inputs to the mod...

BACKGROUND Clinical management of tuberculosis in Russia involves lengthy hospitalizations, in contrast to the recommended strategy advocated by the World Health Organization. METHODS We used Fourier transform, spectral analysis and Student's t-test to analyse periodic and seasonal variations in admission and discharge rates for tuberculosis hospitalizations in 1999-2002, using routinely capt...

Sea-ice thicknesses observed in Canadian coastal waters with helicopter-borne electromagnetic–laser sensors show large interannual variability caused by atmospheric fluctuations in two years for two areas where surveys were repeated, one in the Amundsen Gulf of the Canadian Beaufort Sea and one over the Labrador Shelf. For the Amundsen Gulf, the bimodal ice thickness peaks shifted by 40 cm to t...

Two outbreaks of herpes simplex virus type 1 (HSV-1) infection occurred in three newborns at each of two hospitals, and two of the infants in each case died of disseminated HSV-1 infection. Restriction endonuclease profiles of HSV-1 DNAs isolated from the three in each instance were essentially identical, indicating that they were epidemiologically related. In the first instance, each of three ...

Results are first presented from an analysis of a global coupled climate model regarding changes in future mean and variability of south Asian monsoon precipitation due to increased atmospheric CO2 for doubled (2 · CO2) and quadrupled (4 · CO2) presentday amounts. Results from the coupled model show that, in agreement with previous studies, mean areaaveraged south Asian monsoon precipitation in...
