Title of Document: EVALUATION OF LEACHING PROTOCOLS FOR THE TESTING OF COAL COMBUSTION BYPRODUCTS Jason Louis Becker, Master of Science, 2010 Directed By: Associate Professor Ahmet Aydilek, Department of Civil and Environmental Engineering Beneficial reuse of coal combustion byproducts requires an evaluation of metal leaching potential. Reuse of high carbon fly ash in highway embankment constru...

The detection of partial discharge and analysis of the composition and content of sulfur hexafluoride SF₆ gas components are important to evaluate the operating state and insulation level of gas-insulated switchgear (GIS) equipment. This paper reported a novel sensing material made of pure ZnO and NiO-decorated ZnO nanoflowers which were synthesized by a facile and environment friendly hydrothe...

In this study, the fermentation of raw, inedible poultry byproducts mixed with sugarbeet pulp and dextrose and inoculated with Lactobacillus plantarum and(or) Enteroccocus faecium resulted in a drop of pH in the byproducts to approximately 4.0 to 4.5 within 48 h. To keep the fermented product stable for a period of 21 d, the addition of > or = 3% (wt/wt) of a fermentable carbohydrate was necess...

Marine macroalgae is a promising carbon source that contains alginate and mannitol as major carbohydrates. A bioengineered ethanologenic strain of the bacterium Sphingomonas sp. A1 can produce ethanol from alginate, but not mannitol, whereas the yeast Saccharomyces paradoxus NBRC 0259-3 can produce ethanol from mannitol, but not alginate. Thus, one practical approach for converting both alginat...

The formation of halogenated solvent artifacts was investigated in common analytical solvents exposed to free chlorine, chloramines, and free bromine. Three brominated solvent artifacts [3-bromo-3-methyl-2-butanol (BMB) ,l-bromc-2-methyl-2-propanol, and bromoacetone] were identified by gas chromatography/mass spectrometry in methyl tert-butyl ether or pentane exposed to free bromine. These same...

A series of photo-Fenton reactions have been performed for the degradation of 2,4,6-trinitrotoluene (TNT) in a 4.2-l reactor. The degradation reaction rate of TNT followed a pseudo-first-order behavior; and the rate constants for 2.4mW cm(-2)UV only, 2.4mW cm(-2)UV/H(2)O(2), Fenton, photo-Fenton (2.4mW cm(-2)) and photo-Fenton (4.7mW cm(-2)) were 0.002min(-1), 0.007min(-1), 0.014min(-1), 0.025m...

Though potentially useful, agricultural byproducts are often discarded because of the lack of specific applications in many industries. However, they have suitable properties for use in the paper industry, according to recent literature. In this study, the suitability of rice husk, peanut husk, and garlic stem as raw materials for the manufacture of a new lignocellulosic bulking agent was inves...

Steamconditioning (desuperheating) is an essential and critical part of sugar production, particularly with reference to the processing of expressed juice where criticalsteamtemperatures are most necessary to ensurefinal quality. Desuperheating is a simpleprocess that is not widely understood in principle and is much abusedin its practical application and operation. The purposeof this paper is ...

There is a significant potential to increase the sustainability of fishing and aquaculture industries through maximization processing byproducts. Enzymatic hydrolysis provides an opportunity valorize downstream fish industry byproducts for production protein hydrolysates (FPH) as source bioactive peptides (BAP) with health benefits. Deteriorative oxidative reactions may occur during enzymatic b...

sepals and petals are byproducts from saffron production process that waste without any use in iran. these byproducts containing a lot of anthocyanin and natural antioxidants.the aim of this study is determine efficiency of extraction and measurement of antioxidant activity and anthocyanin pigments of pollen and anther of saffron flower ,using mixed solvent of ethanol and hydrochloridic acid 1....
