As an ambient atmospheric pollutant, fine particulate matter (PM2.5) has posed significant adverse impacts on public health around the world. To attenuate population exposure risk to PM2.5 pollution, greenspace been considered as a promising approach. Little is known, however, about attenuating of landscapes risks at various locations, scales, and levels. This study employed hotspot analysis, w...

Fatty acid methyl esters (FAMEs) were used to `®ngerprint' soil microbial communities that evolved during 25 years of wheat-fallow cropping following native mixed prairie sod at Sidney, Nebraska, USA. Total ester-linked FAMEs (EL-FAMEs) and phospholipid-linked FAMEs (PL-FAMEs) were compared for their ability to discriminate between plots remaining in sod and those cropped to wheat or left fallo...

Urban green and blue space (GBS) significantly impacts the diffusion range of atmospheric particulate matter. By determining distance matter (PM2.5 PM10) in Shanghai, combined with GBS landscape pattern index, this study completed a stepwise multiple regression equation correlation analysis to explore relationship between morphological structure spatial configuration on particles. The results s...

PM2.5 refers to particulate matter (PM) in air that is less than 2.5 μm in aerodynamic diameter, which has negative effects on air quality and human health. PM2.5 is the main pollutant source in haze occurring in Beijing, and it also has caused many problems in other cities. Previous studies have focused mostly on the relationship between land use and air quality, but less research has specific...

There have been several indications (1, 2) that the amylase found in serum is derived from sources other than the pancreas or salivary glands. For this reason we wished to determine whether any indication of fractionation of serum amylase could be obtained by paper electrophoresis. Although several accounts of the fractionation of amylase in serum are found in the literature, some involving pre...
