Computational Analysis of Molten Salt Eutectics
No full textMolten Salt Reactors (MSRs) operate at higher temperatures and lower pressures than traditional Light Water Reactors (LWRs), making them up to 20% more efficient, inherently safer, and more compact. Furthermore, all nuclear waste isotopes are reusable, making them a promising candidate for clean, sustainable energy
WaterSaver: A Smart Solution for Sustainable Water Reuse
No full textWater conservation is crucial worldwide, and the WaterSaver device addresses this by collecting and reusing water from sinks, showers, and faucets. It purifies the water without harmful chemicals, making it safe for reuse. This system reduces water waste, promotes eco-friendly habits, operates efficiently with low energy consumption, and produces no harmful emissions
High-Velocity Pulsar Kicks via Anisotropic Neutrino Emission
No full textObservations reveal that some neutron stars (NS) exhibit high velocities, reaching over 1000 km/s in some instances. This cannot be attributed to the orbital velocity of the NS around our Milky Way galaxy, as it is around 250 km/s on average. The origin of this phenomenon, known as a pulsar kick, is not fully understood and remains a subject of debate among astrophysicists.
During NS formation, the rotation and strong (potentially asymmetric) magnetic field of its progenitor star may result in an asymmetric collapse of the star\u27s core plasma. If this is the case, we might anticipate the formation of dense neutron matter slightly offset from the center of the forming NS, which will be the source of subsequent neutrino radiation. This offset results in an imbalance of neutrinos reaching opposite sides of the NS, creating a net momentum of neutrino radiation into space and propelling the NS in the opposite direction.
Due to strong interactions of high energy (~10-100 MeV) neutrinos with dense neutron matter, we expect the neutrinos to propagate throughout the NS in a diffusive manner. Hence, we used a diffusion model to investigate neutrino emissions from an offset source and analytically proved that it will result in significant anisotropic emissions. From this, we derived a novel linear relationship between the velocity of a pulsar kick and the offset percentage (relative to NS radius), with the proportionality constant dependent solely on the average energy of the formed neutrinos. This formula predicts kickback velocities consistent with observational data from small asymmetries (2-7% offset for 100 MeV neutrinos). Our findings suggest that an offset neutrino source can indeed account for significant recoil velocities and thus, it seems a full theory explaining pulsar kicks should most certainly include anisotropic neutrino emission as a primary cause

Real-Time Control System for Hybrid Rocket Performance Analysis
No full textThe Mechanical Engineering Department at Weber State University is creating a high-temperature materials testbed using hybrid rocket technology for the Miller Advanced Research and Solutions Center. This technology provides enhanced safety and controllability through a control valve, which regulates oxidizer flow to achieve a stable mass flow into the combustion chamber
Assessing Community Attitudes Towards Homelessness and Services
Get PDFA collaborative, community-engaged research project was done to better understand Utah communities\u27 attitudes and beliefs towards homelessness and evaluate for needed services for homeless individuals across Cache, Carbon, Utah, and Uintah counties. Through comprehensive data collection and analysis, this project will help identify community perceptions, challenges, and gaps in services, enabling providers to better tailor their efforts to meet the unique needs of homeless individuals within these counties. Ultimately, the research will foster more informed, responsive, and compassionate support systems for homeless populations across these diverse regions

Geochemical and Stratigraphic Characterization of the Morrison Formation and Cedar Mountain Formation Contact in the Island Park Quadrangle, Uintah County, Utah
Get PDFThe Upper Jurassic Morrison Formation and Lower Cretaceous Cedar Mountain Formation are among the richest sources of dinosaur fossils. Despite a 24-million-year gap in time (the Jurassic–Cretaceous unconformity), these formations are difficult to distinguish due to their similar rock types and colors. In Utah\u27s Island Park quadrangle (IPQ), these formations are not separated on existing geological maps. This study focuses on identifying and understanding the formational boundary between them using field observations, stable isotope analysis, clay mineralogy, and chemical techniques such as X-ray diffraction (XRD) and X-ray fluorescence (XRF).
Unlike other areas where a conglomerate layer marks the boundary, the IPQ lacks this feature. Instead, distinct yellow-orange and red layers, along with changes in mineralogy and chemical composition, help pinpoint the boundary. For example, the Morrison Formation contains kaolinite, whereas the Cedar Mountain Formation includes calcite, gypsum, and sepiolite. The chemical data also indicate intense weathering at the boundary, corresponding to the observed color changes. The two formations reflect different climates: the Morrison Formation was deposited in a wetter environment, whereas the Cedar Mountain Formation formed under drier and cooler conditions influenced by nearby mountains. These climatic differences are also evident in carbon and oxygen isotopes, which align with regional and global climate trends. This study provides new tools to identify the Morrison–Cedar Mountain boundary in the IPQ and enhances understanding of the climate and environmental shifts during this time. These findings can help clarify similar and widespread unconformities in the geological record
