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, ...
