The History And Significance Of Taxidermy Bird Collections In North America: Bgsu's Own Undervalued Collection And Its Future, Kristin Burnside
The History And Significance Of Taxidermy Bird Collections In North America: Bgsu's Own Undervalued Collection And Its Future, Kristin Burnside
Honors Projects
Taxidermy, despite its association with the bizarre and outlandish, has a rich history and culture that helped to define post-Civil War America and its pursuit of knowledge and reconnection with nature. With the widespread publication and availability of how-to guides, natural history collecting and taxidermy became accessible to any individual regardless of age, gender, or class. The hobby required physicality and courage to collect unique and interesting specimens, and intellect and creativity to conserve and display them, all of which inherently connected the avocation with respect. With varying levels of success, hobbyists experimented with different chemicals, such as arsenic, in …
Standardization Of A Latent Blood Visualizer Based Upon Dna Degradation, Kailey M. Van 'T Hoff
Standardization Of A Latent Blood Visualizer Based Upon Dna Degradation, Kailey M. Van 'T Hoff
Honors Projects
Latent blood visualizers have been used in forensic science since 1937 beginning with Luminol. These visualizers through different types of reactions react with trace amounts of blood that cannot be seen with the naked human eye. These different reactions produce color that can then be seen by examiners. The four types of latent blood visualizers that were compared is luminol, leuco crystal violet, fluorescein, and bluestar. Luminol and bluestar use chemiluminescence, fluorescein uses florescent, and leuco crystal violet uses oxidation to react with iron in hemoglobin. At crime scenes when blood is detected which includes with the blood visualizers the …

Examining Bacteriophage Reliance On The Tola Protein Of Escherichia Coli, Ellen Davis
Examining Bacteriophage Reliance On The Tola Protein Of Escherichia Coli, Ellen Davis
Honors Projects
With the ever-growing crisis of antibiotic resistant bacteria, bacteriophage provide an important potential alternative therapy to treat infections when antibiotics are ineffective. For this reason, it is important to understand the mechanisms bacteriophage use to enter their bacterial host cell. The cellular envelope of the gram-negative bacterium E. coli contains a protein system known as Tol-Pal, which utilizes energy from the Proton Motive Force to carry out several cellular functions, including some associated with cellular division and outer-membrane stability. Certain bacteriophage take advantage of the energy produced by this system to cross the bacterial cell membrane. One important protein of …

How Can Stem Retention Rates At Bgsu Be Increased Both In And Out Of The Classroom?, Josalyn A. Coffee
How Can Stem Retention Rates At Bgsu Be Increased Both In And Out Of The Classroom?, Josalyn A. Coffee
Honors Projects
Previous research in STEM student retention rates showed a gap in knowledge regarding why this group of student experience higher rates of burnout than other groups of students. This study investigated the barriers STEM students at BGSU experienced. A survey was sent out to STEM and non-STEM students alike that asked questions regarding student’s personal history before attending BGSU, their course experiences at BGSU, and the levels of support they have outside of BGSU. The survey data showed that there was little difference in the rates that students switch majors solely based on being in the STEM field. The data …
Antimicrobial Activity Of Bacterial Virus Components: An Empirical Investigation Of The Killing Capacity Of Toxins From Burkholderia, Kyle Walny
Honors Projects
Given the growing issue in healthcare of antibiotic resistance, effective and safe alternative treatment methods are required. One of these possible alternative treatment methods is bacteriotoxins including bacteriocins and tailocins. The focus of this study is a bacteriotoxin from Burkholderia cenocepacia (ATCC 25608), which was induced for toxin using a modified UV light induction procedure and tested against a variety of Pseudomonas and Burkholderia for its killing capacity. Various other pathogenic strains were then induced with UV light and tested. The results showed that the toxin from ATCC 25608 was very effective against most of the Burkholderia tested and warrants …
Pectin And Alginate Extraction To Treat Liquid Cafo Manure, Clare Sunderman
Pectin And Alginate Extraction To Treat Liquid Cafo Manure, Clare Sunderman
Honors Projects
For this project, various extraction methods were used to extract pectin from Pastinaca Sativa and alginate from Macrocystis. These extractions were then dried and used in treating 250mL of manure along with a CaCl2 or FeCl3 coagulant. It was found that CaCl2 was not as effective as FeCl3 in coagulating manure. But the results obtained suggest that pectin and alginate obtained with a simpler extraction method is just as effective as the highly purified and refined pectin and alginate produced for the food industry, in the treatment of CAFO manure. The liquid portion of the …
The Experiences Of Black Women Pursuing Advanced Degrees In Stem, Denaja Haygood
The Experiences Of Black Women Pursuing Advanced Degrees In Stem, Denaja Haygood
Honors Projects
Black women are severely underrepresented in science, technology, engineering, and math (STEM) fields. While the underrepresentation of professional Black women in STEM has been well-researched, the pipeline problem of the education of Black women in STEM has been overlooked. The number of Black women pursuing STEM degrees dramatically decreases as the level of education increases. This gap in the literature is problematic, because Black women are still severely underrepresented in STEM-focused advanced degree programs. A small but growing literature indicates that Black women tend to experience frequent forms of discrimination, feelings of isolation and less satisfaction with their graduate programs, …
Unsupervised And Supervised Learning For Rna-Protein Interactions And Annotations, Kateland Sipe
Unsupervised And Supervised Learning For Rna-Protein Interactions And Annotations, Kateland Sipe
Honors Projects
This project analyzed the base and amino acid interactions and annotations through the use of unsupervised and supervised learning techniques. For unsupervised learning, clustering found the data was not able to be distinguished into clear groups which matched the original annotations through kmeans clustering and hierarchical clustering. For supervised learning, the use of random forest, glmnet, and deep learning neural networks were successful in creating accurate predictions. However, machine learning likely will not be able to replace the original complex program, but could be used for possible simplification.
Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib
Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib
Honors Projects
Excess amounts of phosphorus and nitrogen flowing into Lake Erie from agricultural fields in Northwest Ohio has led to several harmful algal blooms (HABs). One potential source of those nutrients is manure applied to fields for fertilizer. Manure from confined animal feeding operations (CAFOs) is 95-98% water with only ~3% solids and nutrients, thus physical transportation is expensive relative to the value of the agricultural nutrients. Furthermore, once manure nutrients are applied to agricultural fields, they are relatively easily mobilized to waterways by precipitation. More than 800 lab-scale tests have been used to optimize the treatment of CAFO manure with …
Converting Chemical Signatures In Vaterite Otoliths To Aragonite Otoliths In Steelhead Trout: Developing A Partition Coefficient, Jamie Justice
Converting Chemical Signatures In Vaterite Otoliths To Aragonite Otoliths In Steelhead Trout: Developing A Partition Coefficient, Jamie Justice
Honors Projects
Otoliths are small bones near the brain of teleost fish that aid in hearing and balance. Otoliths are typically composed of a polymorph of calcium carbonate called aragonite; however, when stressed, fish may transition to producing a less dense polymorph called vaterite. Otoliths are typically used in studies of fish natal origin or migration patterns because 1) otoliths grow concentrically around an origin (birth point), 2) the material in the otolith is not replaced over time, and 3) microelements (Sr and Ba) can be incorporated into the otoliths in proportion to elemental ratios in the water (i.e., when fish move …

The Influence Of Juncus-Rhizosphere Dissolved Organic Matter On Coastal Plankton Communities, Brittany Zepernick, Robert Michael Mckay, George S. Bullerjahn, Jeffrey W. Krause, Behzad Mortazavi
Honors Projects
Many aquatic plants produce copious amounts of dissolved organic matter (DOM) which enters surrounding waters and potentially stimulates planktonic activity. In the northern Gulf of Mexico, Juncus roemarianus (i.e. black needlerush) is a dominant marsh grass species residing in coastal zones and barrier islands. The below-ground biomass i.e. rhizosphere, can be consistently submerged, serving as a potential source of DOM to the surrounding waters. The lability and possible stimulatory effect of J. roemarianus DOM was examined for three plankton communities collected within the discharge region of Mobile Bay and adjacent waters of Gulf Shores, Alabama (less affected by Mobile Bay). …
The Relationship Between Time Of Day, Mood, And Electroencephalography (Eeg) Asymmetry, Morgan Tantillo
The Relationship Between Time Of Day, Mood, And Electroencephalography (Eeg) Asymmetry, Morgan Tantillo
Honors Projects
Previous researchers have had success in finding a correlation between exercise and an increase in positive mood. Researchers have also found a correlation between time of day and mood. The current study will explore the relationship between time of day, mood, and electroencephalography (EEG) asymmetry. The study utilized a convenient sample of ten undergraduate students at Bowling Green State University. Participants had baseline EEG recordings taken, and then participated in moderate exercise, followed by another EEG recording. Participants’ mood was assessed through a self-reported mood questionnaire before the condition as well as immediately after. Due to multiple statistical tests, the …
Anatomical Markers For Elevated Cognition In Dinosaurs, Thomas Gaetano
Anatomical Markers For Elevated Cognition In Dinosaurs, Thomas Gaetano
Honors Projects
Much research has been conducted on brain evolution within Dinosauria. Dinosaurs were originally believed to be incapable of any advanced cognitive abilities beyond the level observed in modern reptiles. This is likely true for many dinosaurs, but recent discoveries suggest that the non-avian maniraptor dinosaurs shared many physical characteristics with their bird descendants, including body feathers and neural adaptations for flight. By studying cranial endocasts (the braincase of fossilized skulls) using computed tomography (CT), paleontologists are beginning to understand the neural changes that took place across the dinosaur-bird transition. Most of these studies are focused on the development of flight, …

Biolabeling Through The Use Of Water-Soluble Colloidal Quantum Dots, Cody Stombaugh
Honors Projects
Nanomaterials continues to be a growing field of study due to their wide range of potential applications. Quantum dots are artificially synthesized crystalline clusters of atoms able to confine electron motion as a result of their incredibly small size. Recently, medical applications of nanomaterials have expanded greatly. Quantum dots are ideal for biolabeling due to their rather narrow photoluminescence emission peaks. By synthesizing quantum dots of a specific diameter, it is possible to predetermine the peak photoluminescence wavelength of a sample. Through ligand exchange and immunoconjugation of the quantum dots with proteins, it is possible to use the quantum dots …
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …
