Validation of Design For Additive Manufacturing Heuristics for Aperiodic Structures through Application to Regular Structures

Creatore:: Schipper, Paxton
Abstract:: Aperiodic structures cause significant challenges to subtractive manufacturing methods due to the common features such as inaccessible voids within the structure. Additive man- ufacturing presents an appealing alternative for this purpose. The aim of this research is to test analysis heuristics for validity through application to periodic structures. First, a...

Exploring the Gut Microbiome of Captive Elephas maximus Experiencing Abnormal Feces

Creatore:: Singh, Sehajvir
Abstract:: The gut microbiome of all mammals is composed of a diverse commune of microorganisms including bacteria, fungi, archaea, protozoa and viruses 1. Studies have shown a symbiotic relationship between the gut microbiome and host physiology, with there being implications in health and disease progression 2. In captive animals, there has...

Testing and design procedures for electric propellant pumps for suborbital bi-propellant rockets

Creatore:: Verna-Ketel, Dominic
Abstract:: An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...

IUD insertions in nulliparous patients : mitigating pain and anxiety

Creatore:: Seifert, Madeleine
Abstract:: Unintended pregnancy has been found to be one of the most prominent challenges that the public health system is forced to overcome due to the financial and social burdens that accompany it (Yazdkhasti et al., 2015). With nearly 48% of reproductive-age American female patients having experienced at least one unintended...

The Oregon Tooth Journey : developing a researched-centered community engagement project to improve childhood dental health and education throughout Oregon

Creatore:: Cowles, Emily A.
Abstract:: Childhood tooth decay is a prevalent and concerning public health issue that is often misunderstood or dismissed. In Oregon specifically, over 50% of children have experienced at least one instance of tooth decay and these rates are even higher for marginalized communities such as children living in poverty, children of...

Field-use electrochemical sensors for detection of carbamazepine in saliva and water

Creatore:: Minzlaff, Jade
Abstract:: The anticonvulsant drug carbamazepine (CBZ) is a commonly prescribed drug that is used to treat patients with neurological disorders including epilepsy and bi-polar disorder. CBZ has a narrow range of efficacy: Below the therapeutic dose, seizures and other conditions are not controlled, and above the recommended window, patients experience side...

Making the microbial world large : assessing best microbiological engagement and teaching methods for high school students

Creatore:: Boryer, Ellie
Abstract:: With mounting distrust for science, finding effective ways to educate the next generation of scientists has become increasingly important. Microbiology is a prevalent and complex subject and is at the forefront of developing cutting-edge technologies for a more in-depth look into the unseen world. However, many people are only ever...

PCR-based Sequencing System across Chlamydia trachomatis

Creatore:: Roetcisoender, Jake
Abstract:: Chlamydia trachomatis is an obligate intracellular pathogen that affects millions of people worldwide via ocular or reproductive tract infection. Despite obvious differences in site of infection, there has been shown to be high levels of sequence conservation across C. trachomatis. This high level of sequence conservation is hindered with a...

Physiological effects of forb and legume pastures on lactating dairy cows as indicated by blood parameters

Creatore:: Marr, Kaylee M.
Abstract:: Use of secondary metabolites in legumes and herbs as forage for dairy cattle is tested through analysis of blood parameters including beta-hydroxybutyrate (BHBA), cholesterol, urea, creatinine, haptoglobin, bilirubin, thiol groups and advanced oxidation protein products (AOPP). The pasture treatments were grass-based (‘Perun’ festulolium (X Festulolium braunii), ‘Rustler’ tall fescue (Festuca...
