Chromium and its compounds are widely used by modern industries, resulting in large quantities of this element being discharged into the environment. To remove chromium from contaminated soils and ground water, it is necessary to predict chemical and physical processes that control the rate of reactions and transport of chromium...
Tetrachlorethene (PCE) and trichloroethene (TCE) were common solvents used in the 1970’s that are now frequently observed groundwater contaminants. One method of remediating these contaminants is in-situ bioremediation that uses a dechlorinating microbial population. The microbial population performs the sequential reductive dechlorination of PCE and TCE to cis-1,2-dichloroethene (c-DCE), vinyl...
For mid-rise and high rise buildings, slender reinforced concrete (RC) structural walls are commonly used as the main structural elements to resist lateral applied loads in high seismically areas around the globe. These RC structural walls can provide substantial deformation capacity, stiffness, and lateral strength through the contribution of their...
Networks of on-line modules for Digital Signal Processing (DSP) applications have been designed and analyzed in many papers. Various arguments have been made for on-line arithmetic over other bit-serial and parallel approaches. However, the majority, if not all of the on-line network implementations presented throughout the literature do not take...
Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....
The purpose of this study was (a) to develop a valid and reliable attitude
toward science instrument for use with Arabic male students at the secondary
school level, (b) to determine the differences in their attitudes toward science and
in their achievement, and (c) to determine the relationship between measures...
Chlorinated aliphatic hydrocarbons (CAHs) like trichloroethene (TCE) were mostly used to replace drying cleaning fluids which contained hydrocarbons like benzene, and were highly flammable. Through improper disposal, storage, and spills, TCE and its downstream products, like cis-dichloroethene (cDCE) and vinyl chloride (VC), leached into groundwater and threaten human and environmental...

Mohammad Azizian, Committee Member, representing School of Chemical, Biological, and
1,4-dioxane and chlorinated aliphatic hydrocarbons (CAHs) such as trichloroethylene (TCE) and 1,1-dichloroethene (1,1-DCE) are hazardous compounds commonly found in soil and groundwater. Bioremediation through aerobic cometabolism is a potential option for the remediation of these contaminated sites. The purpose of this study was to examine the use of different primary...
As access to potable water grows scarce, there is an increasing reliance on alternative drinking water sources, namely groundwater (WHO, 2018). Chlorinated solvents, such as 1,1,1-trichloroethane (TCA) and 1,2-cis-Dichloroethene (cisDCE) are some of the most ubiquitous groundwater contaminants spread throughout the US. 1,4-dioxane (1,4D) was used primarily in the late...
Commercial utilization of pollinizing varieties of pears is important
both for pear growers and processors in Oregon. A study
was made to determine the suitability of Comice, Packam's Triumph
and Anjou, the three pollinizing varieties of pears, for dehydration, as
compared to the Bartlett variety which is commercially used for...
