We analyze the footpoint separation d and ux asymmetry A of magnetically conjugate double footpoint sources in hard X-ray images from the Yohkoh Hard X-Ray Telescope (HXT). The dataset of 54 solar ares includes all events simultaneously observed with the COMPTON Gamma Ray Observatory (CGRO) in high-time resolution mode. From the CGRO data we deconvolved the direct-precipitation and trap-precipi...

Precipitation is a very important topic in weather forecasts. Weather forecasts, especially precipitation prediction, poses complex tasks because they depend on various parameters to predict the dependent variables like temperature, humidity, wind speed and direction, which are changing from time to time and weather calculation varies with the geographical location along with its atmospheric va...

The mechanism of aqueous contaminant removal by elemental iron (Fe 0 ) materials (e.g., in Fe 0 -H2O systems) has been largely discussed in the “iron technology” literature. Two major removal mechanisms are usually discussed: (i) contaminant adsorption onto Fe 0 oxidation products, and (ii) contaminant reduction by Fe 0 , Fe II or H/H2. However, a closer inspection of the chemistry of the Fe 0 ...

The lake elevation of the Great Salt Lake (GSL), a large closed basin in the arid western United States, is characterized by a pronounced quasi-decadal oscillation (QDO) (Lall and Mann 1995). Wang et al. (2009a) found that the variation of the GSL elevation is very coherent with the QDO of sea surface temperature anomalies in the tropical central Pacific, known as the Pacific QDO (White and Liu...

Highly aqueously dispersible (soluble) TiO2 nanoparticles are usually synthesized by a solution-based sol-gel (solvolysis/condensation) process, and no direct precipitation of titania has been reported. This paper proposes a new approach to synthesize stable TiO2 nanoparticles by a non-solvolytic method - direct liquid phase precipitation at room temperature. Ligand-capped TiO2 nanoparticles ar...

Climate warming and shifting precipitation regimes are affecting biodiversity and ecosystem functioning. Most studies have focused on the influence of warming and altered precipitation on macro-organisms, whereas the responses of soil microbial communities have been neglected. We studied the changes in the abundance, richness, and composition of the entire bacterial kingdom and 16 dominant bact...
