Optimizing the compactness of political districts in Oklahoma
(Oklahoma State University, 2019-04-26)This work explores a mathematical optimization model to determine the optimal political districts for a state. Originally created in 1965 by Hess et al, the model assigns each population unit (such as a county) in the state ... -
Chlamydia trachomatis: The key to human pathogen and host interaction
(Oklahoma State University, 2019-04-26)Chlamydia trachomatis is an obligate intracellular pathogen that is commonly sexually transmitted. While Chlamydia infections are easily treated with antibiotics, there are long-term health consequences such as pelvic ... -
Is phase angle a sensitive biomarker for overall health status?
(Oklahoma State University, 2019-04-26)Bioelectrical impedance analysis (BIA) is used as a non-invasive method of calculating body composition, such as body fat and fat-free mass. It works by transmitting electrical currents throughout the body and assessing ... -
It's a dry heat: Quantifying effects of increasing atmospheric moisture demand on native Oklahoma trees
(Oklahoma State University, 2019-04-26)Anthropogenic climate change is predicted to alter precipitation frequency and intensity across Oklahoma in the coming decades, leading to an increase in the frequency, intensity, and duration of extreme events such as ... -
Identifying and understanding multidrug resistant pathogens isolated from Cystic Fibrosis patients
(Oklahoma State University, 2019-04-26)Cystic Fibrosis (CF) is an autosomal recessive disease caused by a mutated Cystic Fibrosis Transmembrane Conductance Regulator (CFTR), which is a chloride ion channel. When the CFTR gene is mutated, it causes the protein ... -
Role of mycorrhizae in milkweeds: Implications for monarch conservation
(Oklahoma State University, 2019-04-26)As little as 1% of the original expanse of North America's tallgrass prairie remains, and the survival of almost all grassland plants depends on the symbiotic partnership with arbuscular mycorrhizal (AM) fungi. These ... -
Stress response of RsbR protein paralogs in Bacillus subtilis under 1M sodium stress
(Oklahoma State University, 2019-04-26)Stress is a universal phenomenon, and all organisms need a way to cope with it. The Model bacterium Bacillus subtilis has a complex of proteins known as a stressosome that is responsible for sensing stressors in the ... -
Growth inhibition of UV filters on the freshwater microalga Scenedesmus acutus
(Oklahoma State University, 2019-04-26)As the use of personal care products with organic ultraviolet (UV) filters are increasing, so is the exposure risk of these compounds to aquatic ecosystems. This study focuses on the inhibition growth effect of four common ... -
Different RsbR paralogs in Bacillus subtilis affect cell viability when exposed to environmental stress
(Oklahoma State University, 2019-04-26)Stress is a universal phenomenon experienced by all living organisms. Bacteria have to react to stress quickly in order to survive in their environment. Environmental stress can be caused by a variety of factors, including ... -
I am still myself: How the Dust Bowl influenced women's clothing in Oklahoma
(Oklahoma State University, 2019-04-26)Traditionally, research over the Dust Bowl has focused on the causes of the ecological disaster and migrant workers, leaving women an understudied component of this story. Because clothing reflects our circumstances, ideals, ... -
Expression and isolation of the membrane proteoglycan syndecan-1 from E. coli
(Oklahoma State University, 2019-04-26)Syndecan-1 is a membrane proteoglycan, which is a protein with glycosaminoglycans, or long carbohydrate chains, attached to its extracellular domain. The syndecan family is composed of various proteoglycans that each aid ... -
Diurnal patterns in light quality and photosynthesis on creeping bentgrass under tree shade
(Oklahoma State University, 2019-04-26) -
Evaluating the effect of promoter strength on the complementation of deletion mutants in Synechocystis sp. PCC 6803
(Oklahoma State University, 2019-04-26)The CO2 uptake mechanism within Cyanobacteria plays a vital role in our environment due to its photosynthetic ability to uptake CO2 and produce oxygen. Cyanobacteria possesses an inorganic carbon concentrating mechanism ... -
Rules of the game: Congressional representation under a theoretical election reform
(Oklahoma State University, 2019-04-26)This study analyzes the how a change to a proportional representation system would systematically change how the House of Representatives. To study this, I used election data from 53 congressional races and awarded the ... -
Calm before the storm: Comparing the initial stages of tornadic vs. non-tornadic supercells
(Oklahoma State University, 2019-04-26)Supercells are one of the most dramatic displays of weather in Oklahoma, and it is from this type of storm that the majority of tornadoes are produced. But while most tornados are produced by supercells, not every supercell ... -
Identification of new signaling components that govern biofilm formation by P. aeruginosa
(Oklahoma State University, 2019-04-26)Pseudomonas aeruginosa is an opportunistic pathogen that is often associated with severe forms of many infections, including bronchiectasis and infections in the gut. Mortality is increased in patients who become infected ... -

Natural antibiotic alternatives to boost animal immunity and disease resistance
(Oklahoma State University, 2019-04-26)Antibiotics have been used in the feed of livestock and poultry for growth promotion and disease prevention for many decades; however, in recent years, there has been an outcry for elimination of antibiotics in order to ... -
Using zircon geochronology to determine sand provenance in Northeast Oklahoma
(Oklahoma State University, 2020-04-24)Porosity in sandstones is a desired trait, but primary porosity is occluded in sandstone after reaching burial depths of 3 kilometers or more. However, depending on the sandstone's composition, secondary porosity can develop ... -
