Potential For Aquifer Storage And Recovery In Box Elder And Cache Counties, Richard C. Peralta, Tom Lachmar, Mariush Kemblowski

Civil and Environmental Engineering Faculty Publications

Groundwater artificial storage and recovery (ASR) has become a favorable means in the arid west to store water produced in excess of need during winter months for use in drier times of the year. ASR may be accomplished by injection of suitable water into the groundwater system via wells to be pumped out later, or by recovery of seepage via wells from surface water impoundments or infiltration networks. This report will present pertinent hydrogeologic information for the location of an artificial groundwater storage and recovery project in Utah's northeastern Box Elder County.

A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix

Conference papers

Recent international quality standards and European Community legislation have identified new software quality factors. These new factors include suitability, installability and adaptability. Other quality factors need to be reviewed in the light of these developments. This has impacted on established commercial usability evaluation methods to the extent that it is appropriate to ask if these evaluation methods comply with the new standards and legislation. In order to answer this question the commercial evaluation methods need to be appraised (meta-evaluation) using a suitable method appraisal process. This paper describes such an appraisal process which specifically addresses the many considerations raised by …

An Analysis Of Drafting Competencies In Iowa's High Schools, Rodrick A. Thompson

Graduate Research Papers

Teachers in Iowa high schools are expected to have students achieve the competencies identified by the State of Iowa Department of Education. The competencies for Iowa high school engineering-related classes were published in 1991. They were compiled as a result of Senate File 449. Industry leaders, as well as teachers, throughout the state of Iowa who were actively utilizing drafting skills in 1991 helped create the outcome competencies. Since that time, these competencies have not been reviewed or revised and may need updating. The demands of industry change so frequently it is possible these are no longer the appropriate competencies. …

Model For Trace Metal Exposure In Filter-Feeding Flamingos At Alkaline Rift Valley Lake, Kenya, Yarrow M. Nelson, Ramesh J. Thampy, Gideon K. Motelin, Jackson A. Raini, Cynthia J. Disante, Leonard W. Lion

Civil and Environmental Engineering

Abstract—Toxic trace metals have been implicated as a potential cause of recent flamingo kills at Lake Nakuru, Kenya. Chromium (Cr), copper (Cu), lead (Pb), and zinc (Zn) have accumulated in the lake sediments as a result of unregulated discharges and because this alkaline lake has no natural outlet. Lesser flamingos (Phoeniconaias minor) at Lake Nakuru feed predominantly on the cyanobacterium Spirulina platensis, and because of their filter-feeding mechanism, they are susceptible to exposure to particle-bound metals. Trace metal adsorption isotherms to lake sediments and S. platensis were obtained under simulated lake conditions, and a mathematical model was …

Bacterial Stress Responses To 1-Megahertz Pulsed Ultrasound In The Presence Of Microbubbles, Amy Cheng Vollmer, Sylvia D. Sakyiama Kwakye , '98, Matthew Evan Halpern , '98, E. Carr Everbach

Engineering Faculty Works

Members of a panel of stress-responsive biosensors have been used to study the effect of megahertz frequency ultrasound onEscherichia coli. Insonification causes acoustic cavitation, the collapse of oscillating microbubbles in solution, which can damage bacterial cells. A focused 1-MHz ultrasound transducer, capable of generating a spatial peak pulse average intensity of 500 W/cm2, was used to treat liquid bacterial cultures. Stress-responsive promoters fused to luxCDABE allowed the continuous measurement of light produced as a result of protein damage, DNA damage, oxidative stress, and membrane perturbation. A promoter responsive to ammonia limitation was not transcriptionally activated under test conditions. In contrast …

Variability Analysis Of Discrete Cosine Transform Coefficient (Dctc) Features For Speech Processing, Bingjun Dai

Electrical & Computer Engineering Theses & Dissertations

In this research, the variability of Discrete Cosine Transform Coefficient (DCTC) features was investigated. Additionally, a new pitch-synchronous processing method was explored to increase the stability of features and to reduce window effects when compared to the regular method. The noise sources that lead to feature variability were analyzed, and different smoothing methods were tested. It was found that longer frames, frequency warping, time smoothing of the log spectrum, and DCS level time smoothing, all help reduce DCTC variability and increase classification performance. The pitch­ synchronous method was implemented with Matlab. Important processing methods, including pitch period estimation, time­ domain …

Sprinkler Irrigation As A Voc Separation And Disposal Method: Innovative Technology Evaluation Report, Teri Richardson, Paul Depercin, Douglas Grosse, Rena Howard, Ann Kern, Endalkachew Sahle-Demissie, Johnny Springer Jr., Richard Schlenker, Roy F. Spalding

United States Environmental Protection Agency: Publications

This report summarizes the findings of an evaluation of sprinkler irrigation as a volatile organic compound (VOC) separation and disposal method.

Background A need for lower cost, effective treatment alternatives for the disposal of treated contaminated groundwater provided the impetus to conduct a SITE demonstration of sprinkler irrigation since it provides both separation and disposal options. Since the application of irrigation is fairly widespread throughout the United States, there may be an opportunity to employ this as a dual purpose technology; concurrent irrigation and disposal of treated groundwater. In order to determine whether this option is viable, it is necessary …

Climate Change And Nebraska

United States Environmental Protection Agency: Publications

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases — primarily carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. The heat-trapping property of these greenhouse gases is undisputed. Although there is uncertainty about exactly how and when the earth’s climate will respond to enhanced concentrations of greenhouse gases, observations indicate that detectable changes are under way. There most likely will be increases in temperature and changes in precipitation, soil moisture, and sea level, which could have adverse effects on many ecological systems, as well as on …
