AND YUEFENG F. XIE aloacetic acids (HAAs) are a group of disinfection by-products (DBPs) regulated under the Stage 1 Disinfectants/Disinfection Byproducts Rule (D/DBPR). The maximum contaminant level for five HAAs is 60 μg/L. These five regulated HAAs are monochloroacetic acid (ClAA), dichloroacetic acid (Cl2AA), trichloroacetic acid (Cl3AA), monobromoacetic acid (BrAA), and dibromoacetic acid ...

Parameters such as future precipitation, temperature, snowfall, and runoff were modeled using PRECIS regionalclimate modeling system in Iran with the horizontal resolutions of 0.44×0.44°C in latitude and longitude under SRESA2 and B2 scenarios. The dataset was based on HadAM3p during the periods of 1961-1990 and 2071-2100. Theoverall precipitation error of the model in the period of 1961-1990 w...

The article describes a step-by-step strategy for designing a universal comprehensive vision of a vast majority of financial research topics. The strategy is focused around the analysis of the retrieval results of the word processing system Serelex which is based on the semantic similarity measure. While designing a research topic, scientists usually employ their individual background. They rel...

We assess the random and systematic uncertainties affecting the central England temperature (CET) record since 1878 on daily, monthly and annual time scales. The largest contribution to uncertainty in CET on all these time scales arises from areal sampling, followed for annual and monthly CET by thermometer calibration. For the daily series, random thermometer precision and screen errors are th...

Atmospheric electric field diurnal variation measured in fair weather conditions over the ocean surface has a typical form which is called unitary variation. It associated with global time and occurs simultaneously all planet. However, variation, ground, depends on many local factors. The maximum of potential gradient, at Paratunka observatory, close to maximum. In paper we show that this deter...
