The Three Rivers Solid Waste Authority (TRSWA) operates a MSW landfill outside Jackson, South Carolina (USA) at which leachate ammonia concentrations are of concern. droplet spraying/misting system (known as the Lilypad system) in their pond to enhance both evaporation and, possibly, volatilization. overall goals this study were determine fate nitrogen and ultimately quantify role plays enhanci...

Thermal energy was shown to be efficiently converted into electrical power in a thermally regenerative ammonia-based battery (TRAB) using copper-based redox couples [Cu(NH3)4 /Cu and Cu(II)/Cu]. Ammonia addition to the anolyte (2 M ammonia in a copper-nitrate electrolyte) of a single TRAB cell produced a maximum power density of 115 1 W m 2 (based on projected area of a single copper mesh elect...

The failure of Viking Lander thermal volatilization (TV) (without or with thermal degradation)-gas chromatography (GC)-MS experiments to detect organics suggests chemical rather than biological interpretations for the reactivity of the martian soil. Here, we report that TV-GC-MS may be blind to low levels of organics on Mars. A comparison between TV-GC-MS and total organics has been conducted f...

In current study, the effects of Iranian rice cooking method (Kateh) on residue levels of 41 pesticides were investigated. The pesticides were selected according to Iranian National Standards Organization (INSO) regulations and covered 18 permitted and 23 banned pesticides belonging to different chemical classes such as organophosphate, triazole, and carbamate. A 250 g portion of rice sample wa...

Inhibition of microbial uricase in poultry manure is critical to reduce NH3 volatilization, because hydrolysis of uric acid by microbial uricase is the first step in the production of NH3 gas in poultry manure. Three experiments were conducted to evaluate the effects of minerals on uricase activity and NH3 volatilization from poultry manure. In Experiment 1, an in vitro enzyme assay was used to...

mold powders are fluxing agents used as raw materials in the steel industry, which play very important role inprocessing stability and final surface quality of a product. surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. heat flux across the interfacial gap depends on thermal properties of s...

Modeling of the high altitude portion of reentry vehicle trajectories with DSMC or statistical BGK solvers requires accurate evaluation of the boundary conditions at the ablating TPS surface. Presented in this article is a model which takes into account the complex ablation physics including the production of pyrolysis gases, and chemistry at the TPS surface. Since the ablation process is time ...
