Landfill leachates are often treated on-site before disposal to municipal wastewater treatment plants, although variations in leachate composition and organic loading continue to have negative impacts on downstream treatment processes. Leachate samples were collected from four landfills both before and after on-site treatment to evaluate the extent of biological treatment. The samples vary in a...

The article presents a plasma chemical technology for processing solid fuels, using examples of bituminous and brown coals. Thermodynamic and experimental investigation of the technology was made. The technology allows producing synthesis gas from the coal organic mass and valuable components (technical silicon, ferrosilicon, aluminum, and carbon silicon, as well as microelements of rare metals...

In this study, we applied the MM5/CAMx model system over Switzerland for winter and summer periods in 2006. The focus is on the formation and transport of aerosols and the contribution of various sources to the aerosol formation both in winter and summer seasons. Our model system uses three nested domains with 27 km (Europe), 9 km (central Europe) and 3 km (Switzerland) resolutions. The concent...

This paper aims to explore the regular structural patterns and the associated electronic properties of a group of hybrid networks based on BiBr3 and aromatic thioethers, with emphasis on structurally correlating the organic molecules with the BiBr3 aggregates as well as the overall hybrid networks. It was found that extended BiBr3 chains tend to be associated with the slender 4-methylthiophenyl...

We report four experimental strategies for controlling the three-dimensional arrangement of molecules in multicomponent organic crystals, exploiting confocal Raman microspectrometry to quantify the three-dimensional spatial distributions. Specifically, we focus on controlling the distribution of two types of guest molecule in solid organic inclusion compounds to produce composite core-shell cry...

Organic-aqueous liquid (phenol) extraction is one of many standard techniques to efficiently purify DNA directly from cells. With effective mixing, the cell components naturally distribute themselves into the two fluid phases in order to minimize interaction energies of the biological components with the surrounding solvents. The membrane and protein partition into the organic phase while the D...

The major drawbacks of existing Distributed Knowledge Management Architectures (DKMAs) are highlighted and a new organic reference architecture, which solves most of those drawbacks, is presented. The proposed reference architecture is based on a well-known organic model, the Viable Systems Model (VSM). The viable systems architecture provides a structure for the design and implementation of di...

low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. it was thought that the hplc is the best method of the determination of organic acids in the apple juice. in this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extr...

According to the pseudo-ideal mixing assumption employed in practically all chemical transport models, organic aerosol components from different sources interact with each other in a single solution, independent of their composition. This critical assumption greatly affects modeled organic aerosol concentrations, but there is little direct experimental evidence to support it. A main experimenta...
