This study evaluated the bacterial distribution and the survivability of bacteria associated with different particle size ranges in the sump water and sediments within two structural Best Management Practices (BMPs), called Vortechs, installed at two different sites in Providence, Rhode Island. Ten rain storms were sampled in year 2004. Five pathogenic indicator bacteria, E. coli, enterococci, ...

THIS paper is an analysis of an unusual outbreak of cholera in a confined community of 7,000 more or less disabled British and Dutch prisoners of war. By the middle of May, 1943, disquieting rumours reached us of outbreaks of cholera among railroad construction parties in Central Thailand. All these rumours agreed on two things: the outbreak was severe and facilities for treating the cases were...

Trends in anthropogenically driven episodic acidification associated with extended winter snow melt/rain episodes between 1983 and 1998 were investigated for two streams in Nova Scotia, Canada. The anthropogenic contribution to Acid Neutralization Capacity (ANC) was analysed using the Boreal Dilution Model (Bishop et al., 2000) modified by applying a sea-salt correction to all input hydrochemis...

Surface water sampling in 2007-2010 measured the occurrence of carbamates and metalaxyl during base flow conditions and wet weather events in southern Ontario surface waters. Carbaryl, metalaxyl and pirimicarb were the most frequently detected compounds. In 2008 these three compounds were detected in over 50 % of the samples. Overall mean concentrations of carbaryl and metalaxyl over the course...

The aim of this study is to investigate sociobehavioral risk factors from the prenatal period until 36 months of age, and the caries increment from 24 to 36 months of the child in Thailand. The data utilized in this study come from the prospective cohort study of Thai children (PCTC) from prenatal to 36 months of the child in Mueang Nan district, Northern Thailand. The total sample size recruit...

Many general circulation models (GCMs) share similar biases in the representation of the intertropical convergence zone (ITCZ) in the Atlantic, even when they are forced with the time series of the observed sea surface temperature (SST). Specifically, they overestimate precipitation in the Southern Hemisphere in boreal spring and in the Caribbean region in boreal summer. The majority of the mod...

The WMO Laboratory Intercomparison of Rainfall Intensity (RI) Gauges described in a companion paper was the very first attempt at understanding the performances of various types of rainfall intensity gauges in controlled laboratory conditions, and provided quantitative information regarding various errors associated with RI measurements. The conclusions report that all instruments analyzed were...
