The range of total metallic/metalloid elements and chlorine concentration was between 0.04 and 189渭g/g, and from below detection to 825渭g/g, respectively. Unexpectedly, samples varied in types and levels of constituents between the western and eastern parts of the country. The enrichment of ...
Basically, the conversion of these “recalcitrant” resource relies on the use thermochemical or enzymatic processes to break down the complex structure of the lignocellulosic material into its main constituents: cellulose, hemicellulose, and lignin. After a single multistage separation procedure, each com...
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Triglycerides are the main constituents of vegetable fat and body fat in humans and other animals. They are also present in the blood to enable bidirectional transference of adipose fat and blood glucose from...
Ultra Low Sulfur Diesel Fuelmeans diesel fuel that has a sulfur content of no more than fifteen parts per million. Hydrofluorocarbonsmeans compounds that only contain hydrogen, fluorine, and carbon. Injectionmeans the injection of carbon dioxide streams into the storage site; ...

The copolymer sheathing exhibited only fair resistance to the aviation turbine fuel and the hydraulic fluid. As the major organic constituents of bilge fluids, are fuels and hydrocarbon based lubricants, polyurethane cable sheathing is suitable for use in bilge spaces. 展开 ...
摘要:The transient behavior of a polymer electrolyte membrane fuel cells (PEMFC) system under an improved adaptive predictive control with robust filter (APCWRF) is analyzed using a nonlinear dynamic, control-oriented model. Sudden changes in the stack current are associated with the abrupt changes...

Under heavier engine loads and higher temperatures, larger amounts of lubricants are used, enhancing their evaporation, and leading to the presence of their constituents in the exhaust particulates. However, oxidative pyrolysis and the partial oxidation of aliphatic hydrocarbons from the fuel could ...
Further discussion on the variation of PM2.5, its constituents, and gaseous pollutants is presented in SI section S3.1. 3.1. Source apportionment of elemental PM2.5 (measured using Xact 625i) The elements measured using the Xact 625i were subjected to source apportionment using PMF. The input ...
