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...
Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...
Investigations were conducted to determine the effect of prerigor pressurization (15,000 psi, 37°C, 2 min.) of beef muscle on the subsequent retail/case-life characteristics of the treated meat. In addition, the activity of the calcium activated factor (CAF) of prerigor pressurized (PRP) muscle was also investigated. For fresh beef samples, PRP...
Coopworth sheep, a newly available genotype, were compared with
other genotypes in two trials to assess cumulative lamb and wool
production and contributing components related to survival, reproduction
and growth, and for the effects of ewe body weight on reproductive traits.
In a third trial, various genotypes generated in the...
As the fifth generation of mobile communication systems (5G) is being deployed, massive multiple-input multiple-output (MIMO) serves as one of its enabling technologies where reliable and ultra low latency communications are achieved while being power and spectrum efficient. This thesis studies the security aspect of massive MIMO system from the...
Catastrophic earthquake and tsunami events that resulted in significant loss of life and property over the past two decades have raised the global awareness regarding the need to understand the response of communities and their built environment to multi-hazard extreme events. In recognition to this impending threat to the coastal...
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...
This study identified new compounds with pest control activities. The two sources of candidates that were followed here were the main heartwood extract of Alaska Yellow Cedar (AYC) constituents and several semi-synthetic counterparts. Five compounds were isolated and identified for the first time in AYC heartwood in this research: two...
