An Evaluation Of The Effects Of Sub-Chronic Ketamine Exposure On Rodent Memory As Assessed By The Odor Span Task In Female Rats, Angela Marie Thomas

Dissertations

Though numerous studies have been undertaken to explore the mechanisms of action of antidepressant medications, little is known about the origins of the disorders they treat. Recently, the therapeutic value of ketamine as a treatment for depression was recognized by the Food and Drug Administration. Historically, ketamine has been used in the laboratory setting to induce ‘schizophrenia-like’ symptomology in humans and animals to allow for further study of those symptoms in a controlled environment; a correlation between ketamine use and deficits in memory and cognitive function has been suggested. This study evaluated the impact of sub-chronic sub-anesthetic ketamine on performance …

Analysis Of The Cyclic Behavior And Fatigue Damage Of Low Alloy Steels, Zahra Salemi Najafabadi

Dissertations

Fatigue is the most common type of failure in many structures and components subjected to cyclic loading. Surface effects in fatigued materials are of particular importance, since in most cases the surface is the preferred site of fatigue crack initiation. Microcracks originate at the metal surface due to stress concentration introduced by macro notches and micro defects in the surface layers. The microcrack initiation and propagation are controlled by the localized plastic deformation in the surface layers especially in the initial stage of fatigue failure process. Therefore, the knowledge regarding the cyclically induced changes in deformation resistance at the metal …
