This study focuses on spatial variability of throughfall water and chemistry and forest floor water content within a Douglas fir (Pseudotsuga menziesii, Franco L.) forest plot. Spatial patterns of water and chemistry (NH4 +, NO3 -, SO4 2-, Cl-, Mg2+, Ca2+, Na+ and K+) were compared and tested for stability over time. The spatial coefficient of variation (CV) was between 18 and 26% for amounts o...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...

Content Delivery network architectures are initiatives designed to support the effective delivery of continuous and discrete media to end-users. Mobile devices are now capable of exploiting services such as content delivery, but with the protocols governing the Content Delivery Networks designed for wired networked topologies; an assessment of the impact of mobile devices on the network has nev...

The nitrate contents of various vegetables were analyzed by ion chromatography. It was shown that tahtsai, spinach, chingentsai and pakchoi contained more than 300 mg of nitrate per 100 g of edible portion. There was a significant difference in the nitrate content of leaf, stem and edible portion of chingentsai between summer and winter, and there was a significant difference in the nitrate con...

Total phenolic contents (TPC) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of Artemisia biennis Willd were measured in this work. The antioxidant activity was investigated by three different methods: β-carotene bleaching (BCB) test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and ferrous ion chelating (FIC) assay. Amo...

Content based image retrieval has been emerged as the most innovative area for the research work from the last few years. Image retrieval is basically a method for the extract ion of most crucial characteristics of an image. The primary aim of th is content based image retrieval (CBIR) is to have the exact result within the short period of t ime. Content-based image retrieval is based on the co...
