Effects Of Red Light Intensity On Cultivation And Oxygen Production In Arthrospira Platensis, Abigail Roberts Dec 2022

Effects Of Red Light Intensity On Cultivation And Oxygen Production In Arthrospira Platensis, Abigail Roberts

Honors Theses

Maintaining life sustaining resources during long-term space travel has encouraged scientists to turn their attention to the potential benefits of a cyanobacteria named Arthrospira platensis, commonly known as Spirulina algae. This experiment measures the oxygen production and cell population growth of two structurally different Spirulina cultures under two different levels of red light intensities, 8 µmol/m2/s (high); 3 µmol/m2/s (low). The cell population, oxygen produced, and oxygen produced per cell measurements were observed and recorded at three 24 hour intervals. It was found there was not a significant difference between high and low light intensities when considering the cell concentration …


The Effects Of Light Intensity And Cell Structure On The Cultivation Of Arthrospira Platensis, Taylor Barnhart Dec 2022

The Effects Of Light Intensity And Cell Structure On The Cultivation Of Arthrospira Platensis, Taylor Barnhart

Honors Theses

As scientists explore further into space, more cost-effective resources are needed for long-term space travel. An interesting solution is Arthrospira platensis, a filamentous cyanobacteria high in proteins and nutrients, and known for its helical structure. In unfavorable conditions, coiled spirulina cells become straight. Spirulina converts carbon dioxide gas into pure oxygen and the different cell structures stimulate different responses in oxygen production and cultivation. In these experiments, 2.3 L containers of pure coiled spirulina and mixed (coiled and straight) spirulina were placed into 3 incubators with different light intensities: 51µmol/m2/s, 25µmol/m2/s, 12µmol/m2/s. Each experiment length was 72 hours and the …

This experiment measures the oxygen production and cell population growth of two structurally different Spirulina cultures under two different levels of red light intensities, 8 µmol/m 2Js (high); 3 µmol/m2/s (low). The cell population, oxygen produced, and oxygen produced per cell measurements were observed and recorded at three 24 hour intervals. It was found there was not a significant difference between high and low light intensities when considering the cell …


Effects Of Storage Conditions On Bpa Leaching From Infant Oral Hygiene Products Using Fluorescence Spectroscopy, Emma Bynum May 2022

Effects Of Storage Conditions On Bpa Leaching From Infant Oral Hygiene Products Using Fluorescence Spectroscopy, Emma Bynum

Honors Theses

Infants are at the highest risk of BPA exposure compared to any other stage of life. Because an infant’s endocrine system is developing, exposure to an endocrine-disruptor, such as BPA, can be especially harmful. Bisphenol-A (BPA) is a structural component in many plastic products, which acts as an endocrine-disruptor mimicking estrogen. This hormonal disruption has been linked to obesity, reproductive issues, cardiovascular problems, and the neurodevelopment disorders. While the FDA monitors things like baby bottles, canned goods, and plastic containers for BPA, infantile oral hygiene products are not closely monitored. Previous research tested infant toothbrushes on the market using a …


Bacteriophages: Paving The Road For The Future Of Medicine, Luke Brinkerhoff May 2022

Bacteriophages: Paving The Road For The Future Of Medicine, Luke Brinkerhoff

Honors Theses

Bacteriophages are a possible solution to antibiotic resistance, which is predicted to be detrimental world-wide by the year 2050. Personal field research was also conducted for a project studying the characteristics of two bacteriophages on a single bacterial host.


A Meta-Analysis On The Differences In Neuroplasticity Between Women And Men After Traumatic Brain Injuries, Victoria A. Martin Apr 2022

A Meta-Analysis On The Differences In Neuroplasticity Between Women And Men After Traumatic Brain Injuries, Victoria A. Martin

Honors Theses

The current meta-analysis investigates the differences in neuroplasticity between women and men after a traumatic brain injury (TBI). Research on the differences in neuroplasticity between women and men is relatively new and few studies have reported outcome variables by gender after TBIs. Neuroplasticity is the brain’s ability to adapt and change particularly because of learning or brain injuries. TBI is a leading cause of death and disability worldwide; because of this, learning more about these differences can give scientists and clinicians more information on how to better treat people with brain injuries. Current research is inconsistent on whether there is …


Grasping The Intangible: The Perseverance Of Physical Music Media In A Digital World, Sam Youmans Apr 2022

Grasping The Intangible: The Perseverance Of Physical Music Media In A Digital World, Sam Youmans

Honors Theses

Music is a unique economic good with several interesting characteristics: as an art form, its value is immensely subjective and changes with the culture; it is most widely consumed via online streaming platforms but still embedded onto physical formats and sold through retailers; and the United States music business had to pivot through substantial economic disruption at the turn of the century with the advent of peer-to-peer file sharing. Given the digital world in which we live, this thesis explains why people still purchase music on physical formats. This is accomplished by discussing revenue data from the past few years, …


Developing Novel Water-Soluble Porphyrins For Potential Use As Photosensitizers In Photodynamic Therapy, Kayla R. Whittington Apr 2022

Developing Novel Water-Soluble Porphyrins For Potential Use As Photosensitizers In Photodynamic Therapy, Kayla R. Whittington

Honors Theses

Photodynamic therapy (PDT) is a treatment modality for various illnesses, including some types of cancer. Lung cancer is the leading cause of cancer death in the United States. The prevalence of lung cancer in certain gender, racial, ethnic, and socioeconomic groups add to existing health disparities in the United States. For this reason, it is necessary to address the social determinants underlying lung cancer disparities, as well as improve treatment options. These treatment options should be cost effective, convenient, and increase survival rates. This research focused on synthesizing novel water-soluble porphyrin compounds for use as photosensitive agents in PDT for …


A Comparison Of Stigma Levels For Individuals With Psychological Disorders And Individuals With Intellectual Disabilities, Isabella E. Wood Apr 2022

A Comparison Of Stigma Levels For Individuals With Psychological Disorders And Individuals With Intellectual Disabilities, Isabella E. Wood

Honors Theses

This study compared nine aspects of stigmatization (blame, anger, pity, help, dangerousness, fear, avoidance, segregation, coercion) amongst schizophrenia, binge eating, and intellectual disabilities. The overall MANOVA was significant, F(18, 183) = 89.95, p < .001, Wilks’ Lambda = .10. When the results for the dependent variables were considered separately, all nine dependent variables reached significance (p < .001). Schizophrenia scored highest in all categories except blame and pity. Blame was the highest for binge eating and pity was the highest for intellectual disabilities. Efforts to reduce stigmatization must be tailored to each disorder.


Counseling For Psychosocial Stress Factors Associated With Hearing Loss, Emily Mcmaster Apr 2022

Counseling For Psychosocial Stress Factors Associated With Hearing Loss, Emily Mcmaster

Honors Theses

Audiologists play a major role in helping people with hearing loss learn how to better communicate and how to connect to the world around them. The purpose of this project investigates the extent to which audiologists counsel their clients for the psychosocial stress factors caused by hearing loss, along with determining the extent in which patients with hearing loss feel they would benefit from counseling services implemented into their appointments. In addition to psychosocial stress factors, the thesis will analyze the extent to which clients are educated on their hearing loss and given practical ways to adjust to their loss …
