Optimum Location Of Last-Mined Stope With The Influence Of Backfilling, Huawei Xu, Derek B. Apel

Journal of Sustainable Mining

Many mines in Canada have adopted sublevel stoping method or one of its variations, such as blasthole stoping (BHS) and sublevel longhole retreat (SLR), for the extraction of steeply dipping orebodies. Stope, as the basic excavated element, plays a significant role in the whole process of mining activity. In the mining method of BHS, crossing cuts are excavated at tops and bottoms in each stope for drilling blast holes and transportation of mined out orebodies. Crossing cuts failure may result in prolonged production interruption, fatality, and equipment loss. After the completion of orebodies excavation from the sublevel open stope, the …

Handling surgical instrumentation trays with awkward postures is one of the high-risk tasks performed in the OR that can result in upper extremity (UE) strain. A healthcare system-based hospital in Northern California had five reported upper extremity strain injuries by the surgical technologists (STs) in workplace safety (WPS) performance year (PY) 2018-2019. The project aims to decrease UE strain injuries among STs by improving the quality of surgical instrumentation trays and promoting the culture of safety through …

Helping New Immigrants Adapt To American Culture: Enhancing Students’ Language And Cultural Competence Through The Use Of The Ellen Degeneres Show, Nuchinun Kluaythong

Master's Projects and Capstones

Adult immigrants face many challenges before they can successfully function in a new country. Beyond learning the new language, adjusting to a different and confusing culture can be difficult and discouraging, often eroding the immigrant’s confidence. These interrelated problems are recognized by the English as a second language (ESL) community, and modern approaches to ESL teaching integrate popular culture and the use of authentic language. It also recognizes that an alert and eager mind is important to learning, so the emphasis is put on developing student interest and confidence by making the class relevant, contemporary, and fun.

Direct Observation Of The Formation And Stabilization Of Metallic Nanoparticles On Carbon Supports, Zhennan Huang, Yonggang Yao, Zhenqian Pang, Yifei Yuan, Tangyuan Li, Kun He, Xiaobing Hu, Jian Cheng, Wentao Yao

Michigan Tech Publications, Part 1

Direct formation of ultra-small nanoparticles on carbon supports by rapid high temperature synthesis method offers new opportunities for scalable nanomanufacturing and the synthesis of stable multi-elemental nanoparticles. However, the underlying mechanisms affecting the dispersion and stability of nanoparticles on the supports during high temperature processing remain enigmatic. In this work, we report the observation of metallic nanoparticles formation and stabilization on carbon supports through in situ Joule heating method. We find that the formation of metallic nanoparticles is associated with the simultaneous phase transition of amorphous carbon to a highly defective turbostratic graphite (T-graphite). Molecular dynamic (MD) simulations suggest that …

Creating A Thriving Informatics Culture, Nicholas Webb

Doctor of Nursing Practice (DNP) Projects

Nurses thrive best when they are empowered to make decisions that can positively impact healthcare delivery. Knowledge and application of nursing informatics principles can influence clinical, quality, operational, and financial outcomes in ways that were not available in previous professional nursing generations.

If nursing informatics is the solution, what is the problem? A survey regarding use and attitudes about nursing informatics was taken of chief nurse executives (CNEs) at an integrated, not for profit healthcare system in the Northern California region, where the author oversees the electronic health record (EHR). The results were surprising. Half said they did not know …

Impact Of Cd82 Expression On Acute Myeloid Leukemia Chemosensitivity And Quiescence, Muskan Floren

Biomedical Sciences ETDs

Acute Myeloid Leukemia (AML) patients respond favorably to induction chemotherapy, however, long-term outcomes remain poor due to a high rate of chemoresistance and bone marrow minimal residual disease. To improve long-term patient outcomes, it’s critical to identify regulators of chemotherapy resistance in AML and develop therapies that are directed towards bone marrow resident AML cells. In Chapter 2, we uncover the impact of CD82 expression in AML response to chemotherapeutic treatment and the contribution of Protein Kinase C α (PKCα) and β1 integrin signaling in promoting p38 MAPK activation to support CD82-mediated AML cell survival. In Chapter 3, we …

The tropics are the source of most biodiversity yet inadequate sampling obscures answers to fundamental questions about how this diversity evolves. We leveraged samples assembled over decades of fieldwork to study diversification of the largest tropical bird radiation, the suboscine passerines. Our phylogeny, estimated using data from 2389 genomic regions in 1940 individuals of 1287 species, reveals that peak suboscine species diversity in the Neotropics is not associated with high recent speciation rates but rather with the gradual accumulation of species over time. Paradoxically, the highest speciation rates are in lineages from regions with low species diversity, which are generally …

Implementing Virtual Sitters To Reduce Falls And Sitter Costs, Asia Quovadis Williams Plahar

Doctor of Nursing Practice (DNP) Projects

The setting for this DNP project was a 326-bed, suburban hospital in Northern California that was facing challenges with preventing falls with injury and rising sitter costs. Between May 2018 and June 2019, there were four sentinel events related to falls with significant injuries. This hospital was financially impacted by the growing cost of the expanding sitter program caused by the rising elderly patient population, with demographics requiring one-to-one, in-person sitters to observe them visually. There is ample research demonstrating the utility of video monitoring systems to improve patient safety by reducing falls, enhancing staff safety by reducing workplace injuries …

Exposing Lettuce Plants To Cyanobacteria In A Closed Hydroponics System To Reduce Cyanobacterial Growth And Production, Emily Eberly

Honors Projects

Sandusky Bay is largely populated by cyanobacterial algal blooms, mainly formed by Planktothrix. Fertilizers containing nitrogen and phosphorus run from agricultural lands into the bay, building up excess nutrients forming eutrophic waters. The Planktothrix feed off these nutrients and grow into algal blooms. To determine a potential solution to the growth of these blooms, I implemented a hydroponics system involving Lactuca Sativa for analysis of Planktothrix growth and productivity. Four different nutrient conditions were added to a Planktothrix-only solution and a solution growing Planktothrix with the lettuce in the hydroponics system. The four conditions consisted of no nutrient …

Editorial: Advances And Challenges In Ocean Wave Energy Harvesting, Y Liu, B Ding, B Zhou, P Cong, S Zheng

School of Engineering, Computing and Mathematics

Wave energy resource is abundant and huge due to the vast oceanic area on the planet. On the other hand, exploitation of wave energy has never reached a satisfactory level that can replace to a large extent the traditional fossil fuel. The main disadvantage of wave power is the significantly random variability in several timescales: from wave to wave, with sea state, and from month to month (Falcão, 2010). This poses many super challenges to effectively and efficiently extract power from the sea waves. The present collection of research articles reflects the most recent contributions coming forward on harvesting wave …

Large Global Variations In Measured Airborne Metal Concentrations Driven By Anthropogenic Sources, Jacob Mcneill, Randal V. Martin, Nofel Lagrosas, 35 Co-Authors

SOSE Affiliate: Manila Observatory

Globally consistent measurements of airborne metal concentrations in fine particulate matter (PM_2.5) are important for understanding potential health impacts, prioritizing air pollution mitigation strategies, and enabling global chemical transport model development. PM_2.5 filter samples (N ~ 800 from 19 locations) collected from a globally distributed surface particulate matter sampling network (SPARTAN) between January 2013 and April 2019 were analyzed for particulate mass and trace metals content. Metal concentrations exhibited pronounced spatial variation, primarily driven by anthropogenic activities. PM_2.5 levels of lead, arsenic, chromium, and zinc were significantly enriched at some locations by factors of 100–3000 compared …

The Design And Development Of A Monochrome Volumetric Display Using Laser Diodes And A Rotating Helix Structure, Seth Barger

Honors Theses

As electronic displays and televisions reach near-perfection, the limit of two dimensions has become more evident. Since conventional display technology will soon stale, it is imperative to find new ways of displaying images. This study uses the persistence of vision as the launching point for an original volumetric display technology, fooling the human eye into seeing a volumetric image. Using a rotating helical apparatus and an array of projecting laser diodes, a successful prototype was produced which is capable of displaying a true volumetric image. Based on the success of this primitive experimental prototype, this technology is ready for expansion …
