(Faculty of Graduate Studies and Research, University of Regina, 2021-12)Foam is a complicated but fascinating fluid being widely involved in almost every technological step in petroleum industry, from drilling, well stimulation, enhanced oil recovery (EOR), production, to refining process. Its ... -
Identification and Characterization of Antibiotic Biosynthetic Gene Clusters in Pantoea
(Faculty of Graduate Studies and Research, University of Regina, 2021-08)Antimicrobial resistance is a global health crisis for which new antibiotics are needed. Natural products (secondary metabolites) produced by microbes have been our primary source of antibiotics; however, the search has ... -
Anti-candida and Anti-virulence Activity of Essential Oils and Their Components
(Faculty of Graduate Studies and Research, University of Regina, 2021-10)Candida albicans is one of the most common fungi associated with lifethreatening infections. Treatment of the associated infections is often ineffective in the light of resistance, and so there is an urgent need to ... -
Parkinson's Disease Classification, Monitoring and Optimization of Deep Brain Stimulation
(Faculty of Graduate Studies and Research, University of Regina, 2021-09)Parkinson's disease (PD) alters the brain's anatomy when dopamine releasing neurons die in basal ganglia neural pathways. The resulting alterations force synchronized neuronal activity in beta frequency components in ... -
Social Interaction and Physical Activity among Rural Older Adults
(Faculty of Graduate Studies and Research, University of Regina, 2022-03-30)Physical activity and social interaction are critical components in supporting health and well-being among older adults; therefore, there is significant merit in further exploration of the relationship between these ... -
The Use of Clinical Testing Procedures in the Diagnosis of Motor Control Impairments Associated with Low Back Pain
(Faculty of Graduate Studies and Research, University of Regina, 2021-08)Background: The underlying causes of low back pain (LBP) have been proposed to be associated with motor control impairments that can result in compensatory movement and spinal instability. The Prone Hip Extension (PHE) ... -
The Erdős-Ko-Rado Theorem for Transitive Permutation Groups
(Faculty of Graduate Studies and Research, University of Regina, 2022-03)Given a transitive permutation group \(G \le Sym(\Omega)\), a subset \(F\) of \(G\) is \(\textit {intersecting}\) if any two elements of \(F\) agree on some elements of \(\Omega\). We are interested in the problem of finding ... -
Pore-Scale Imbibition Studies for Tight Rock Systems
(Faculty of Graduate Studies and Research, University of Regina, 2021-12)Imbibition pervasively exists in many natural and industrial processes, such as oil/gas recovery, hydraulic fracturing, the postinjection stage of CO2 sequestration, printing processes, diagnostic tests in biomedicine. ... -
Screening of Potential Polyamine Solvents for Carbon Capture
(Faculty of Graduate Studies and Research, University of Regina, 2021-09)Carbon dioxide (CO2) is one of the main greenhouse gases that significantly contributes to global warming. It is therefore imperative to reduce the amount of CO2 emissions into the atmosphere. Among CO2 capture sorbents, ... -
Extensions of the Erdős-Ko-Rado Theorem to Perfect Matchings
(Faculty of Graduate Studies and Research, University of Regina, 2022-03-31)One of the important results in extremal set theory is the Erdős-Ko-Rado (EKR) theorem which gives a tight upper bound on the size of intersecting sets. The focus of this thesis is on extensions of the EKR theorem to ... -
