Standardization Of A Latent Blood Visualizer Based Upon Dna Degradation, Kailey M. Van 'T Hoff Dec 2022

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 …


Autopsy V. Virtopsy: A New Approach For Postmortem Forensic Examination, Nicole Elaine Lawson Dec 2022

Autopsy V. Virtopsy: A New Approach For Postmortem Forensic Examination, Nicole Elaine Lawson

Honors Projects

Virtopsy as a potential new standard in forensic science investigation in the place of a conventional autopsy. In recent years there have been new advancements across the forensic field and in the scientific world as a whole. These advancements have changed many approaches bringing new capabilities and new challenges and pushback. This report takes a specific interest in the evolution of forensic autopsy. With improvements such as magnetic resonance imaging (MRI), computed tomography scan (CT), X-Rays, and other approaches a new term and technique have been coined Virtopsy. As this new potential approach has come to light the resistance against …


Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman Apr 2022

Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman

Honors Projects

Amblypygids are nocturnal arthropods which live in cluttered habitats and possess the ability to navigate home after displacements of up to ten meters. Homing amblypygids rely on olfactory and tactile information gathered by their antenniform legs to navigate successfully. Given that odor signals encountered in nature are complex and dynamic, navigation via olfaction presents unique challenges related to signal uncertainty. To understand how amblypygids perceive perceive complex odors and what they learn from them, individuals of the subtropical amblypygid P. marginemaculatus were trained to associate a blend of two odors with a shelter and tested on three treatments: the reinforced …


Exploring The Relationship Between Art And Environmental Education, Mackenzie Haynes Apr 2022

Exploring The Relationship Between Art And Environmental Education, Mackenzie Haynes

Honors Projects

To explore the relationship between art and environmental education, I created a lesson plan and then put into practice at Crim Elementary School in a 4th grade art class. The art project had to do with the environment, endangered animals and recyclable materials. I titled the project "Habitat Heroes" and students had to imagine that they were the only people left on Earth along with a few animals and lots of trash. They were tasked with selecting an endangered animal in Ohio from one of five different groups (mammals, birds, reptiles/amphibians, birds and fish) to create a habitat for. The …


Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood Apr 2022

Assessing Environmental Factors That Influence Cyanobacterial Blooms In Skinn Lake, Kloe Atwood

Honors Projects

Global lakes are experiencing an increase in toxic algal blooms that can be damaging to the environment. These blooms are caused by cyanobacteria, specifically a species called Planktothrix. Skinn Lake, in Ohio, is a location of a cyanobacterial bloom that is mainly populated by Planktothrix rubescens. This lake was further examined to identify the major toxin-producing bacteria and identify environmental microbes surrounding the bloom. When the data was examined it was found that the microbiomes of the lake greatly differed between the winter (bloom) months and the summer (non-bloom) months. This difference can be viewed within the nutrient analysis from …


Isolating Bacteriophage For Potential Treatment Of Chronic Multi-Drug Resistant Escherichia Coli Infections, Leila Oswalt Jan 2022

Isolating Bacteriophage For Potential Treatment Of Chronic Multi-Drug Resistant Escherichia Coli Infections, Leila Oswalt

Honors Projects

The misuse and overuse of antibiotics has led to the intense rise in antibiotic resistance. As society transitions into the post antibiotic era, there will be a great need for new therapeutic strategies to address multiple drug resistant bacterial infections. One such method, called bacteriophage therapy, allows for specific targeting of certain pathogenic bacteria through the use of viruses that attack bacteria; termed “bacteriophage” or simply “phage”. Urinary tract infections are among the most common pathological human infections that rely heavily on the use of antibiotics, the major cause of which is the bacterium Escherichia coli. During the Spring 2021-Spring …


The Role Of Elmo5 In Arabidopsis Thaliana Cell Adhesion, Isabel Kristina Ball Jan 2022

The Role Of Elmo5 In Arabidopsis Thaliana Cell Adhesion, Isabel Kristina Ball

Honors Projects

Plant cell growth and development relies on proper cellular adhesion. As the extracellular matrix serves as the area of connection between two cells, its synthesis and maintenance are essential for cellular adhesion. The middle lamella region, the layer of the extracellular matrix between two adjacent cell walls, is diffuse with the polysaccharide pectin due to its delivery by Golgi vesicles early during cell division. A Ruthenium Red screen for cellular adhesion mutants identified the family of 5 ELMO proteins that are critical for proper cellular adhesion. To further our understanding of plant cellular adhesion and pathways of pectin synthesis and …
