DNA barcoding for identifying zooplankton
(Oklahoma State University, 2019-04-27)DNA barcoding is still a relatively new field of study that is gaining popularity as it becomes more available. But there is no single protocol that works consistently and efficiently. While there are protocols that have ... -
Do Anolis lizards recognize heterospecific neighbors?
(Oklahoma State University, 2021-04)Many organisms establish territories, though the reasons are varied and not always understood. Organisms that establish territories often must defend them against invaders. Territorial animals sometimes exhibit “dear enemy ... -
Does coffee affect the validity of an oral abbreviated fat tolerance test in healthy adults?
(Oklahoma State University, 2020-04-24)Objectives: Postprandial triglycerides (TG), or levels of fat in the blood after a meal, are an independent risk factor for cardiovascular disease (CVD) (1). A clinically feasible test to assess postprandial TG has been ... -
Does osteoarthritis pain severity correspond more to inflammation or joint damage?
(Oklahoma State University, 2021-10-09)Post traumatic osteoarthritis (PTOA) develops as a result of injury to the joint. This process involves progressive joint damage and chronic low-grade inflammation that leads to PTOA pain. This summer, I focused on damaging ... -
'Drop' model in the fashion industry: Examining retail strategy and long-term sustainability effects
(Oklahoma State University, 2022-04-15)From a retail giant, Amazon, to luxury fashion brands like Gucci and Burberry, 'drops' as a marketing strategy have been adopted widely by the fashion industry in recent years (Larsson, 2020). The new innovation, the 'drop' ... -
Dying light: Detecting tree mortality risk with chlorophyll fluorescence
(Oklahoma State University, 2019-04-27)Increased greenhouse emissions have altered Earth's climate, resulting in rapid climate change which has brought warm droughts-especially in semi-arid regions-leading to forest die-off and dieback. Physiological stresses ... -
Dynamic simulation and modeling of gripper for applications in autonomous drone catcher
(Oklahoma State University, 2021-10-09)With advancing technology allowing for drones to become more efficient and evasive in their flight paths, researchers are looking for ways to solve the question of how can these drone be caught midair? Drawing inspiration ... -
Effect of acid adaptation on pathogenic bacteria used as challenge organisms for microbial validation of biltong processing
(Oklahoma State University, 2023-04-27)Biltong is a South African dried beef product that has grown in popularity in U.S. markets over the last five years. Unlike traditional American beef jerky, biltong is dried at ambient temperature and humidity after ... -
Effect of idiographic worry on emotional processing
(Oklahoma State University, 2019-04-27)Emotional processing to internal threat is increasingly being studied as a way to evaluate the effect of worry on attention. The current study seeks to use event related potentials (ERPs), specifically the Late-Positive ... -
Effect of increased ruminal proprionate on the expression of hepatic gluconeogenic genes in cattle on a finishing ration
(Oklahoma State University, 2022-04-19)The objective of this experiment was to ascertain if supplementing calcium propionate (CaP) in varying amounts would result in the increased expression of genes related to glucose metabolism in the liver. The study utilized ... -
Effect of microhabitat and body size on toe pad size in arboreal, semi-arboreal, and torrential frogs
(Oklahoma State University, 2019-04-27)Frogs can be classified into specialized microhabitats, and for our study, we chose to focus on arboreal (tree dwelling), semi-arboreal (tree and terrestrial dwelling), and torrential (freshwater stream dwelling) species. ... -
Effect of mitochondrial inhibitor on fresh meat color
(Oklahoma State University, 2021-04)Oxygen consumption is a muscle property that influences beef color. A greater amount of oxygen consumption results in less bloom and darker meat color while lower oxygen consumption produces a more desirable, bright, cherry ... -
Effect of nozzle configuration on thrust of a novel turbojet-turboprop engine for small unmanned aircraft
(Oklahoma State University, 2022-04-19)This paper presents the results of testing the effects of nozzle area ratio , nozzle downstream location propeller shape, and propeller size to determine the feasibility of a variable-cycle turboprop/turbojet powerplant ... -
