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...
As new cost-effective cultivation methods are needed for macrophytic red algae, this experiment expands upon a previously studied land-based approach. The experiment aimed to determine how the fluid dynamics of a previously researched land-based method affected the growth of the macrophytic red alga, Gracilaria Vermiculophylla. A clonal culture of G....
With growing awareness of the negative impacts of the built environment, solutions for dramatic environmental, economic, and social improvements are sparking in all sectors, especially within the construction industry. The work of this thesis aims to quantify and compare social, economic, and environmental impacts of a three-story mass timber structure...
This thesis explores the relationship between design cycle models and knowledge management systems applied to various physical prototypes that the author developed from 2020 to 2023. The author walks through the process of prototyping a potty-training device in OSU’s Prototype Development Lab and an automated testing fixture for her Senior...
Latinas in engineering face discrimination on the intersectionality of their two identities, Latinx and woman. The barriers that happen to them as an indirect effect of previous or existing institutional systems of oppression are called systemic barriers. Coming from the lens of four subjects, in a ranking of the barriers...
In the United States, 58.7% of the spinal cord injuries that occur each year result in some degree of tetraplegia, this leads to reduced control of upper limb muscle. One surgery that can restore some upper limb function is a brachioradialis (BR) to flexor pollicis longus (FPL) tendon transfer surgery,...
Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...
Menstrual health and hygiene insecurity is a global health issue people across the world face, particularly in developing countries. According to the World Bank, an estimated 500 million lack access to adequate menstrual products, and “to effectively manage their menstruation, women and girls require access to water, sanitation, and hygiene...
Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...
Advances in plant construction within the energy and chemical process industries require inexpensive process intensification (PI) technology as a means to reduce plant size for enabling modular construction. One form of PI is microchannel process technology where arrays of microchannels, having hydraulic diameters on the order of 0.1 to 1...
