Effect Of Haemonchus Contortus Excretory/Secretory Protein On Differences In Host Neutrophil Migration, Hannah Grace Teddleton

Graduate Theses, Dissertations, and Problem Reports (ETD)

An excretory/secretory (E/S) product, common to many helminths, is neutrophil inhibitory factor (NIF) which negatively affects neutrophil migration and activity. Due to differences in neutrophil accumulation between parasite resistant St. Croix STC and parasite susceptible Suffolk (SUF) sheep, we hypothesized that Hc-NIF may inhibit migration of SUF and not STC neutrophils. Previous studies have demonstrated that Hc produces NIF but is not commercially available. To test our hypothesis, neutrophils were cultured from STC and SUF sheep in the presence of Ancylostoma caninum-derived NIF (Ac-NIF) and measure chemotaxis to Interleukin-8 (IL-8), HcLA or H. contortus third-stage excretory/secretory (E/S) products. Neutrophils were …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Big game hunting is an important source of revenue and recreation in the United States. Of big game species, white-tailed deer (Odocileus virginianus) are the most heavily pursued. White-tailed deer are a widespread generalist species, capable of existing at high densities. Hunting is often used as the primary method of managing deer populations, particularly in the eastern United States, where there is a lack of large predators. When populations reach high densities, there can be negative effects on the environment and conflicts with humans. Managers must consider both creating adequate hunting opportunities and reducing negative impacts when managing …

Investigating The Effect Of Using Humorous Threats In Recreation Area Rules Signage To Influence Behavioral Intentions, Jacob Timothy Vargas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Communicating the importance of rules and warnings to visitors of recreational parks through signage can be difficult. However, it is one of the most important things to keep visitors safe. Oftentimes, these signs use fear of punishment or injury to discourage certain behaviors. According to studies following the Extended Parallel Processing Model (EPPM), using threats can backfire and cause visitors to use maladaptive fear responses to counteract a threat message if the content is too extreme or too psychologically close. Humor is a versatile tool that can be used to grab attention, temper perceptions, and influence decision-making. Comedians like Jon …

Laser Deposition Additive Manufacturing Of Multi-Material And Metal-Ceramic Composite Structures, Manikanta Grandhi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increasing performance requirements of modern industrial systems, coupled with the imperative for decarbonization, necessitate a fundamental rethinking of metallic component design and manufacturing. Traditional materials, with their inherent limitations in property optimization, susceptibility to degradation, and weight constraints, are proving insufficient. Multi-material joining offers a potential solution, enabling designers to strategically integrate diverse materials with specific, tailored properties into single component. Functionally graded materials (FGMs) and oxide dispersion strengthened (ODS) materials are prime examples of this approach, delivering substantial improvements in wear resistance, thermal regulation, high-temperature resilience, and overall weight efficiency. However, conventional manufacturing approaches further exacerbate the limitations …

Triggered Online System Re-Identification Applied To Model Predictive Control Using Gaussian Processes, Daniel Augusto Kestering

Graduate Theses, Dissertations, and Problem Reports (ETD)

Safety, product quality, enhanced performance, and increased profit all depend on the control of chemical and energy processes. However, operational issues can lead to control challenges, especially when processes are subject to disturbances during their operation. Process control methods work best when processes operate close to their designed operat- ing conditions, but lack of performance or other issues may occur when the process is far from such conditions. To overcome these challenges, in this dissertation, online model re- identification is proposed for Model Predictive Control (MPC). This involves reassessing the predictive model of an advanced controller, namely MPC, when re-identification …
