Risk Assessment Of Hazardous Materials Transported By Rail Through The Wku And Bowling Green, Kentucky Corridor, Rebecca Center
Risk Assessment Of Hazardous Materials Transported By Rail Through The Wku And Bowling Green, Kentucky Corridor, Rebecca Center
Mahurin Honors College Capstone Experience/Thesis Projects
There has been multiple risk assessments on highways for hazardous material, however there is few in hazardous rail transportation. In this study, I will create a risk assessment of the railway through WKU. Using the CAMEO system I will created threat zones and plot them in the city every half-mile to conclude where people and infrastructure will be affected the most. I discovered that there were large amounts of chemicals passing by, some are extremely dangerous to human and environmental health.
Assessment Of Estrogenic Compounds In A Wastewater Treatment Plant Influent And Effluent, Alexandra L. Hunter
Assessment Of Estrogenic Compounds In A Wastewater Treatment Plant Influent And Effluent, Alexandra L. Hunter
Mahurin Honors College Capstone Experience/Thesis Projects
Estrogenic compounds have been found in surface waters downstream from wastewater treatment plant effluents. In the aquatic environment, these hormones are shown to cause feminization and sterility of aquatic organisms, thus altering aquatic ecosystems upon which human health depends. In order to assess estrogenic compounds at a local wastewater treatment facility in Franklin, KY, Environmental Protection Agency Method 539 [Determination of Hormones in Drinking Water by Solid Phase Extraction (SPE) and Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (LC/ESI-MS/MS)] was modified to measure levels of these contaminants in wastewater influent and effluent. This method requires use of LC/ESI-MS/MS analysis. A …
Applications Of Latin Hypercube Sampling Scheme And Partial Rank Correlation Coefficient Analysis To Mathematical Models On Wound Healing, Hannah M. Pennington
Applications Of Latin Hypercube Sampling Scheme And Partial Rank Correlation Coefficient Analysis To Mathematical Models On Wound Healing, Hannah M. Pennington
Mahurin Honors College Capstone Experience/Thesis Projects
Latin hypercube sampling and Partial Rank Correlation Coefficient procedure (LHS/PRCC) can be used in combination to perform a sensitivity analysis that assesses a model over a global parameter space. Through this analysis, the uncertainty of the parameters and therefore the variability of the model output in response to this uncertainty can be observed. Latin hypercube sampling divides the parameter space into equiprobable regions and sample without replacement, producing a global, unbiased selection of parameter values. For montonic, non-linear relationships, the correlation between the outputs and parameters can be understood by performing a Partial Rank Correlation Coefficient procedure. This sensitivity analysis …
Analysis Of Seed Preference Trials Of Red Veld Rats And Smith's Bush Squirrels And Trap Effectiveness In The Lowveld Of South Africa, Brooke A. Barber
Analysis Of Seed Preference Trials Of Red Veld Rats And Smith's Bush Squirrels And Trap Effectiveness In The Lowveld Of South Africa, Brooke A. Barber
Mahurin Honors College Capstone Experience/Thesis Projects
Large tree species in South Africa face reproductive decline, especially older trees that provide ecosystem connectivity. Management of Balule Nature Reserve, an extensive private nature reserve in South Africa, wanted to investigate the roles rodents play in the recruitment and survival of select tree species. Two large tree species of concern, marula (Sclerocarya birrea) and knobthorn acacia (Acacia nigrescens) are dominant, habitat providers and red bushwillow (Combretum apiculatum) is a smaller and more common, prolific seed producer. I investigated whether rodents, specifically red veld rats and Smith’s bush squirrels, may play a detrimental role …
The Effects Of New Materials And Teaching Methodologies On Low-Level Biology Courses, Rebecca L. Garrison
The Effects Of New Materials And Teaching Methodologies On Low-Level Biology Courses, Rebecca L. Garrison
Mahurin Honors College Capstone Experience/Thesis Projects
A new generation has entered higher education that learns differently from generations before. To meet the changing needs of this generation, Western Kentucky University’s Biology Department introduced e-textbooks and e-materials from McGraw Hill™ publishing in the fall of 2013 to most low-level classes. A foreseen product of this shift was a change in the way that some faculty taught and assessed their classes. This study assesses the changes in pedagogical techniques among professors of 100- and 200-level biology classes due to the new e-text and e-materials. Syllabi were collected from these classes pre- and post-implementation and common characteristics were inductively …
Seed Preference Trials Of Namaqua Rock Mice And Rodent Density In The Lowveld Savanna Of South Africa, Whitney L. Walker
Seed Preference Trials Of Namaqua Rock Mice And Rodent Density In The Lowveld Savanna Of South Africa, Whitney L. Walker
Mahurin Honors College Capstone Experience/Thesis Projects
Large trees important in the South African savanna are in decline. Initially, climate change and elephants were thought to be the cause. However, all reasons for the decline are unknown. I investigated how Namaqua rock mice potentially affect recruitment of tree seedlings through seed predation in South Africa. I used live traps to capture rodents during the dry season of June-August on Balule Nature Reserve (BNR). I exposed the mice to seed preference trials in enclosures to determine if they would eat seeds of three target tree species; marula (Sclerocarya birrea), knobthorn acacia (Acacia nigrescens), and …
Dietary Overlap Of Native White Bass And Introduced Yellow Bass In Barren River, Micaela L. Montgomery
Dietary Overlap Of Native White Bass And Introduced Yellow Bass In Barren River, Micaela L. Montgomery
Mahurin Honors College Capstone Experience/Thesis Projects
In the Barren River Lake of south central Kentucky, native white bass, Morone chrysops, has experienced a decline in population after the introduction of yellow bass, Morone mississippiensis. These species are competing for resources due to an overlapping diet, likely contributing to the decline of the white bass. To explore this hypothesis, I examined the stomach contents and otoliths of white and yellow bass caught during their spawning time in spring 2012. There were 40 yellow bass and 128 white bass collected in Barren River upstream of Barren River Lake. Analysis of stomach contents revealed that both white and …
Trypanosoma Cruzi Prevalence In The Domestic Canine Population In Central And Eastern Kentucky, Katelyn Cox
Trypanosoma Cruzi Prevalence In The Domestic Canine Population In Central And Eastern Kentucky, Katelyn Cox
Mahurin Honors College Capstone Experience/Thesis Projects
Domestic canines are regarded as natural sentinelsfor the transmission of vector-borne pathogens since infection in an owner’s dog suggests the presence of the vector in or around the household. In collaboration with the University of Kentucky’s Veterinary Diagnostic Lab in Lexington, Kentucky, we have investigated the prevalence of Trypanosoma cruzi (the causative agent of Chagas disease) in canines from central and eastern Kentucky via a serological test, polymerase chain reaction (PCR), and DNA sequencing. In addition, Canine SNAP 4Dx plus tests (Idexx Laboratories, Inc.) were used to determine the prevalence of four other vector-borne pathogens: Ehrlichia canis/ewingii, Borrelia burgdorferi, Anaplasma …

Horses' Responses To Receiving Masterson Method™ Integrated Equine Performance Bodywork™ Treatments, Carla O. Beu
Mahurin Honors College Capstone Experience/Thesis Projects
This research documents the changes of comfort levels in horses resulting from receiving Masterson Method™ Integrated Equine Performance Bodywork™ treatments. The Masterson Method™ (MM) is a bodywork technique used to identify and release accumulated tension from the equine body. MM focuses on three main anatomical junctions: the poll-atlas junction, neck-shoulder-wither junction, and the sacroiliac junction. Research documentation includes pre and post treatment evaluations, the treatments, owner questionnaires, and cribbing observations. Also, all evaluation and treatment sessions were videotaped with the intent of further analysis for changes in range of motion, flexibility, and comfort level as applicable. Each horse received a …
Non-Adaptive Phentypic Plasticity: Morphology, But Not Swim Speed, Of Spotted Salamander Larvae Is Affected By "Terrestrial" And "Aquatic" Herbicides, Mitchell Schooler
Non-Adaptive Phentypic Plasticity: Morphology, But Not Swim Speed, Of Spotted Salamander Larvae Is Affected By "Terrestrial" And "Aquatic" Herbicides, Mitchell Schooler
Mahurin Honors College Capstone Experience/Thesis Projects
- Phenotypic plasticity, although ubiquitous, may not always be advantageous. In cases where individuals expressing an induced phenotype outperform non-induced individuals, the phenotypic plasticity is considered adaptive. Conversely, if the individuals with an induced phenotype underperform relative to non-induced individuals, then the plasticity is maladaptive. A final possibility is that both induced and non-induced individuals perform equally well (or poorly). This would be a case of non-adaptive (i.e. neutral) phenotypic plasticity.
- We investigated the mode of phenotypic plasticity induced by four glyphosate-based herbicides in larvae of the spotted salamander, Ambystoma maculatum (Shaw, 1802), by determining whether the herbicides induced different morphologies, …
Corbicula Fluminea Food Web Ecology: An Experimental Transplant Approach In A Karst Riverine System, Autumn Smith
Corbicula Fluminea Food Web Ecology: An Experimental Transplant Approach In A Karst Riverine System, Autumn Smith
Mahurin Honors College Capstone Experience/Thesis Projects
The Asiatic clam Corbicula fluminea is a filter-feeding habitat generalist. Carbon isotopic composition (δ13C) of C. fluminea body tissue was compared between reaches of Kentucky’s upper Green River that differed in Cladophora growth. Corbicula fluminea from an upstream reach with little Cladophora was translocated to a downstream reach with high Cladophora levels. Individuals from both reaches were placed in mussel silos in the same downstream reach in autumn 2012 and again in 2013 for 77 and 119 days, respectively. Flow during 2012 consisted of no high flow events until late autumn. Flow patterns in 2013 were consistently higher and more …
