Marine Nitrogen Cycle Across the Cretaceous-paleogene Boundary at Maud Rise
(2016-07-01)
The marine nitrogen cycle across the Cretaceous-Paleogene (K-Pg) boundary at Maud Rise provides insight into an important environmental variable during the K-Pg extinction event, the redox state of the water column. This ...
Pumpability of Optimized Grade Aggregates
(2016-05-01)
This work validates the gradation boundaries presented by Dr. M. Daniel Cook in his 2015 dissertation. A large variety of concrete gradations were pumped through a pipeline and their pressures were measured, analyzed, and ...
Impact of B, B-carotene-9’,10’-Oxygenase2 (BCO2) on Mitochondrial Function and Hypothalamic Metabolism
(2016-05-01)
B,B-carotene-9’,10’-oxygenase2 (BCO2) is a carotenoid cleavage enzyme localized to the inner membrane of mitochondria. Hypothalamus is the key brain region that regulates energy homeostasis through nutrient sensing and ...
Mid-season Prediction of Wheat Grain Yield Potential and Nitrogen Response
(2016-12-01)
Soil nutrient management has made significant advances in efficiency, especially with nitrogen (N) fertilization. Nonetheless, there is still room for improvement surrounding mid-season prediction of grain yield and ensuing ...
Development and demonstration of 2D dosimetry using optically stimulated luminescence from new Al2O3 films for radiotherapy applications
(2016-05)
Scope and Method of Study: The goal of this work was to develop and demonstrate a 2D dosimetry system based on the optically stimulated luminescence (OSL) from new Al2O3 films for radiotherapy applications. A 2D laser-scanning ...
American Black Bear Ecology in Southeastern Oklahoma: Population Status and Capture Methodology
(2016-05-01)
Black bears (Ursus americanus) were extirpated from Oklahoma in the early 1900s but have since recolonized eastern portions of the state after successful reintroductions in Arkansas. After initial demographic studies were ...
Variable selection to improve classification in structure-activity studies and spectroscopic analysis
(2016-05)
A genetic algorithm for variable selection to improve classifications is explored and validated on a wide range of data. In one study, 147 tetralin and indan musks and nonmusks compiled from the literature for the purpose ...
Separation of D- and L-Methamphetamine in Postmortem Samples via Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
(2016-05-01)
Methamphetamine, or meth, is a commonly abused drug in the United States, especially Oklahoma. Meth exists in the form of two enantiomers, d-meth and l-meth. D-meth affects the central nervous system and causes the addictive ...
Components of Employee Development Program in Manufacturing Industry
(2016-05-01)
This exploratory study was intended to identify what components of an employee development program are currently being used, barriers companies face in providing such a development program, and how a development program ...
Does early intervention reduce the risk of future emotional and behavioral problems in children with Autism Spectrum Disorder
(2016-07)
Objective: Early Intensive Behavioral Intervention (EIBI) is the leading recommended treatment for children with Autism Spectrum Disorder (ASD). Children with ASD are at a substantially higher risk for developing symptoms ...
