Plants can effectively remove airborne particles from ambient air and consequently improve air quality and human health. The accumulation of particles on the leaf surfaces of three plant species with different epicuticular wax ultrastructures, such as thin films, platelets and tubules, was investigated during leaf expansion in Beijing under extremely high(More)
Strain A54(T) was isolated from rhizospheric soil of turf grasses irrigated with reclaimed water in Taoranting Park, Beijing, China. Phenotypic, chemotaxonomic and polygenetic analyses established the affiliation of the isolate to the genus Dyadobacter. Strain A54(T) possessed 97.7, 94.4 and 94.7 % 16S rRNA gene sequence similarity with respect to the type(More)
Wetland plant rhizosphere microorganisms play a significant role in the purification of ecological restoration of reclaimed water replenishment wetlands. In this study, water quality discriminant analysis indicated the wetland had a distinctive role in the purification of total nitrogen (TN), total phosphorus (TP), and nitrate (NO3 −) from reclaimed water,(More)
INTRODUCTION The most reliable liver safety signal in a clinical trial is considered to be 'Hy's Law cases' defined as subjects experiencing hepatocellular injury and serum bilirubin elevations with no more likely cause than study drug. However, there is little published data to support the current biochemical criteria for Hy's Law cases or their use to(More)
Beijing city, capital of China, has experienced a rapid urban expansion over the past two decades due to accelerated economic growth. The fast urban spatial expansion has led to the substitution of the natural vegetation-dominated land surfaces by impervious materials. This has a significant impact on the ecosystem on a local to global scale. Therefore, a(More)
Urban tree species mapping is an important prerequisite to understanding the value of urban vegetation in ecological services. In this study, we explored the potential of bi-temporal WorldView-2 (WV2, acquired on 14 September 2012) and WorldView-3 images (WV3, acquired on 18 October 2014) for identifying five dominant urban tree species with the(More)
Extracting watershed features from DEM (Digital Elevation Model) is a very important task in Hydrologic study, and also it is the pre-process of hydrological simulation analysis. This paper introduces a very useful method for Hydrological simulation analysis based on extracting watershed features from DEM using Arc Hydro Tools. Arc Hydro is a geospatial(More)
