The Distribution And Life Cycle Of Alliaria Petiolate In Lincoln, Nebraska, Caleb Pharris

Department of Environmental Studies: Undergraduate Student Theses

Alliaria petiolata (Garlic Mustard) is a biennial alien invasive plant species of the Brassicacea family. It is responsible for displacing native plant species throughout North America and its management has proven to be extremely difficult. Recently several populations of Alliaria petiolata have been discovered in southwestern Lincoln, Nebraska. The spread of Alliaria petiolata is a concern for natural resource managers and the general public. Due to the difficulty of its control, Alliaria petiolata is capable of creating monocultures which diminish the aesthetic value of an ecosystem. While most commonly found in the understory of hardwood forests, it is capable of …

Feasibility Study For Make-Up Water Quality For Cooling Tower By Electro-Coacgulation Process, Sasipim Manasilp, Cattaleeya Pattamaprom

Applied Environmental Research

Cooling tower was a type of heat transfer equipment which was used to enhance heat rejection to the environment by increasing the surface contact between water and air. Water used in the cooling tower system had to be pretreated to prevent scaling and corrosion. As most factories in the northern part of Bangkok utilized both tap water and groundwater, which was known to contain large amount of minerals and suspended solids, water pretreatment was crucial before entering cooling towers or the heat-exchanging systems. Typical water pretreatment system consisted of sand filtration, carbon adsorption and ion-exchange resin adsorption to remove particles …

Efficiency Of Triple Superphosphate Fertilizer To Stabilize Cadmium In Different Soil Texture Characteristics, Chatchavaporn Yingsombat, Usarat Thawornchaisit

Applied Environmental Research

This research investigated the effectiveness of Triple Superphosphate (TSP) as a stabilizing agent for cadmium (Cd) in three representative soils having different texture characteristics (loamy-sand, clay loam, and clay soils). Results showed that addition of TSP proved to be an effective method for reduction of Cd leachability in all Cd contaminated soils. The partitioning of Cd from the potentially available phase to the more stable phase was observed in all TSP treatments based on the sequential extraction data. Moreover, performance of TSP to immobilize Cd depended on soil types and compositions. The effectiveness of TSP to reduce Cd leachability was …

Effects Of Ferrocene On The Solubilization Of Alkanes In A Microemulsion System, Saravanee Singtong, Chantra Tongcumpou, David A. Sabatini

Applied Environmental Research

Ferrocene is a metallic additive that has been used to boost the octane number of gasoline. Even though ferrocene is not an environmental contaminant of high concern, it can be found in soil contaminated with gasoline. Due to its organometallic nature, ferrocene may affect the phase behavior of other alkanes which has been contaminated to the environment and limit their removal using surfactant-enhanced aquifer remediation (SEAR). Therefore, the aim of this work was to investigate the effects of ferrocene on the solubilization capacity of alkanes in micellar surfactant solutions. The solubilization capacity and column study of alkanes with and without …

Microbial Community Function In Freshwater Wetland Soils: Using Extracellular Enzyme Analysis To Study The Effect Of Moisture And Vegetation, Aaron Porter

Theses and Dissertations

Differences in microbial function via extracellular enzyme activity (EEA) were investigated to determine the potential effects of hydrology and plant-soil-microbe interactions in a young non-tidal freshwater riparian wetland. To study these relationships, three plots were established along a moisture gradient (Wet, Intermediate, Dry) within VCU Rice Center Within each main plot, five subplots were left undisturbed while another five were cleared of all above-ground plant biomass. Homogenized soil cores (top 10 cm) were analyzed for pH, redox, C:N, soil organic matter (SOM) content, saturation, and temperature. Microbial function was assessed using extracellular enzyme analysis. For most enzymes, a site difference …

Investigating The Influence Of Computer Programs On Perception And Application Of Mathematical Skills, Neil M. Bly

Theses and Dissertations

Existing research suggests an intuitive relationship between mathematics and computer programming. These previous studies have focused primarily on the cognitive connection and have ignored the potential impact of programming on an individual's perception and application of mathematical skills. By surveying and interviewing a variety of participants, this study aims to provide a descriptive foundation for the experiential side of cognitive correlations and causalities. These phenomenological accounts, garnered from individual interviews of seven different programmers, indicate four specific areas of interest. First, learning to program provided context for many abstract concepts. Second, programming illustrated the important distinction between understanding the application …

Life History Benefits Of Residency In A Partially Migrating Pond-Breeding Amphibian, Kristine L. Grayson, Larissa L. Bailey, Henry M. Wilbur

Biology Faculty Publications

Species with partial migration, where a portion of a population migrates and the other remains residential, provide the opportunity to evaluate conditions for migration and test mechanisms influencing migratory decisions. We conducted a five-year study of two populations of red-spotted newts (Notophthalmus viridescens), composed of individuals that either remain as residents in the breeding pond over the winter or migrate to the terrestrial habitat. We used multistate mark-recapture methods to (1) test for differences in survival probability between migrants and residents, (2) determine if migrants breed every year or skip opportunities for reproduction, and (3) estimate the frequency …

Leadership In Sustainable Chemicals Policy: Opportunities For Oregon, Jennifer H. Allen, Alexis Dinno

Institute for Sustainable Solutions Publications and Presentations

Oregon is uniquely positioned to lead in the development of safer alternatives to toxic chemicals. Existing chemicals policy in the United States does not comprehensively protect human health or the environment from the potential impacts of chemical exposure. Very few of the 84,000 chemical substances produced, processed or imported for commercial purposes in the United States have been studied for health and environmental impacts. The federal Environmental Protection Agency has access to only limited information about potential health or environmental hazards. Manufacturers have the right to withhold what they consider to be confidential business information. Because of this lack of …
