Integrating A Virtual Science Outreach Into The Science Classroom Through Participatory Action Research, Shelby Anne Montague

Electronic Theses and Dissertations Archive

Calls for increased involvement in science outreach have come from scientists (Alberts, 2018; Friedman, 2008), from professional organizations (Jayaratne et al., 2003; Lee, 2018; Toolin, 2004) and from funding agencies (Broadening Participation, 2008; Catsambis, 1995) to increase students’ interest in science, technology, engineering, and mathematics (STEM) and STEM careers. One model of science outreach is the scientist in the classroom model, where a STEM professional visits a school classroom either in-person (Peker et al., 2012; Pratt and Yezierski, 2018) or virtually (Barry et al., 2022; McCombs et al., 2007). The St. Jude Virtual Journal Club is a scientist in the …

Integrated Tire Wear Buildup And Rainfall-Runoff Model To Simulate Tire Wear Particles In Stormwater, Matthew Dupasquier, Jaime Hernandez, Alondra Gonzalez, Cesar Aguirre, Walter M. Mcdonald

Civil and Environmental Engineering Faculty Research and Publications

This paper presents an approach to integrate tire wear buildup and rainfall-runoff models to simulate tire wear buildup on road surfaces and its subsequent transport in stormwater runoff events. To do so, a buildup model is presented based on vehicle kilometers traveled, vehicle type, vehicle speed, and road roughness within a watershed. This buildup model was integrated into an EPA SWMM model that simulated the runoff of tire wear particles in twelve watersheds in the San Francisco, CA bay area. Results demonstrate that tire wear particle buildup within the watersheds ranged between 0.4 and 0.51 (kg/km2) per hour. Applied to …

Exploring The Impact Of A Student-Faculty Partnership Program At A Hispanic Serving Institution, Alyssa G. Cavazos, Lesley Chapa, Javier Cavazos Vela

Writing and Language Studies Faculty Publications

Guided by a strength-based framework and counter-storying lens, we use a qualitative case study approach (Cook-Sather, 2020; Cook-Sather & Motz-Storey, 2016) to explore students’ experiences with a teaching partnership program. A Students as Learners and Teachers (SaLT) model to student-instructor partnership positions students as consultants in a faculty member’s course in which they are not currently enrolled (Cook-Sather, 2020). Following a case study analysis with student and faculty partners in a SaLT program at a HSI, several themes were identified. Themes emerging from student participants included: empathy, personal growth, solidarity, and feedback awareness. Faculty partners’ themes included: receptivity, resistance, and …

Smith, Christopher M. Orban, Juan J. Manfredi, Kyle Frische, Michael L. Dexter, Enam A. Chowdury, Anil K. Patnaik

Faculty Publications

We present detailed characterization of laser driven fusion and neutron production (∼10⁵/second) employing 8 mJ, 40fs laser pulses on a thin (< 1 µm) D₂O liquid sheet employing a measurement suite. At relativistic intensity (∼5×10¹⁸W/cm²) and high repetition-rate (1 kHz), the system produces consistent D-D fusion, allowing for consistent neutron generation. Evidence of D-D fusion neutron production is verified b y a measurement suite with three independent detection systems: an EJ-309 organic scintillator with pulse-shape discrimination, a ³He proportional counter, and a set of 36 bubble detectors. Time-of-flight analysis of the scintillator data shows …

Carrier Dynamics In Green Iii-Nitride Leds Using Small-Signal Electroluminescence, Xuefeng Li

Optical Science and Engineering ETDs

Solid-state lighting has achieved significant success over the past two decades, but the low quantum efficiency of green LEDs (i.e., the “green gap”) remains a barrier to full red-green-blue (RGB) displays in numerous applications. Combating efficiency reduction in longer-wavelength LEDs requires understanding the relative roles of intrinsic effects (e.g., wave-function overlap, carrier-current density relationship, phase-space filling (PSF)) vs. extrinsic effects (e.g., material degradation due to increased defect density, compositional inhomogeneities, etc.). A systematic study of the carrier dynamics in InGaN/GaN LEDs is very important for understanding the origin of the green gap and for providing solutions to improve the efficiency …

An Exploration Of Tissue Specific Impedance Using Microneedle Based Wearable Sensors, Kaitlyn J.H. Read

Nanoscience and Microsystems ETDs

Within this research, I have developed a microneedle-based wearable sensor for plants and fungi, to measure the electrical impedance of different tissues. Electrical impedance measures the physical properties of a material while allowing complex biological systems to be modeled onto a simplified electrical circuit. Microneedles allow for electrical impedance to measure specific tissues without the insulative properties of the cuticle and can be applied to delicate tissues. I have demonstrated the tissue specificity, novel attachment methods, as well as use on both plants and fungi. In chapter 1, I applied microneedle-based impedance to the leaf midrib of a sorghum and …

Application Of An Empirical Density Law Via Python For Aqueous Plutonium Chloride Systems For Mcnp6, Riley Bulso

Nuclear Engineering ETDs

A predictive density law has been implemented and developed into a Python tool to reduce bias and the high degree of conservatism in criticality safety calculations for aqueous plutonium chloride systems. Based upon available data and parameters, an empirical method was used to create this law. This method was used in the development of a Python tool to predict the density and composition of such a solution, which may then populate material data in an MCNP6 input file.

This tool and the density law equation have been verified against experimental data points for accuracy. Density is predicted with a maximum …

Galectin-3 Cooperates With Cd47 To Suppress Phagocytosis And T-Cell Immunity In Gastric Cancer Peritoneal Metastases, Yibo Fan, Shumei Song, Yuan Li, Shilpa S Dhar, Jiankang Jin, Xiaodan Yao, Ailing W Scott, Melissa Pool Pizzi, Jingjing Wu, Lang Ma, George A Calin, Samir Hanash, Linghua Wang, Michael Curran, Jaffer A Ajani

Faculty, Staff and Student Publications

UNLABELLED: The peritoneal cavity is a common site of gastric adenocarcinoma (GAC) metastasis. Peritoneal carcinomatosis (PC) is resistant to current therapies and confers poor prognosis, highlighting the need to identify new therapeutic targets. CD47 conveys a "don't eat me" signal to myeloid cells upon binding its receptor signal regulatory protein alpha (SIRPα), which helps tumor cells circumvent macrophage phagocytosis and evade innate immune responses. Previous studies demonstrated that the blockade of CD47 alone results in limited clinical benefits, suggesting that other target(s) might need to be inhibited simultaneously with CD47 to elicit a strong antitumor response. Here, we found that …

Response Of Co2 And Ch4 Emissions From Arctic Tundra Soils To A Multifactorial Manipulation Of Water Table, Temperature And Thaw Depth, K Best, D Zona, E Briant, C-T Lai, Da Lipson, Kr Mcewing, Sj Davidson, Wc Oechel

School of Geography, Earth and Environmental Sciences

Significant uncertainties persist concerning how Arctic soil tundra carbon emission responds to environmental changes. In this study, 24 cores were sampled from drier (high centre polygons and rims) and wetter (low centre polygons and troughs) permafrost tundra ecosystems. We examined how soil CO2 and CH4 fluxes responded to laboratory-based manipulations of soil temperature (and associated thaw depth) and water table depth, representing current and projected conditions in the Arctic. Similar soil CO2 respiration rates occurred in both the drier and the wetter sites, suggesting that a significant proportion of soil CO2 emission occurs via anaerobic respiration under water-saturated conditions in …

A Paracrine Circuit Of Il-1Β/Il-1r1 Between Myeloid And Tumor Cells Drives Genotype-Dependent Glioblastoma Progression, Zhihong Chen, David H. Gutmann, Et Al.

2020-Current year OA Pubs

Monocytes and monocyte-derived macrophages (MDMs) from blood circulation infiltrate glioblastoma (GBM) and promote growth. Here, we show that PDGFB-driven GBM cells induce the expression of the potent proinflammatory cytokine IL-1β in MDM, which engages IL-1R1 in tumor cells, activates the NF-κB pathway, and subsequently leads to induction of monocyte chemoattractant proteins (MCPs). Thus, a feedforward paracrine circuit of IL-1β/IL-1R1 between tumors and MDM creates an interdependence driving PDGFB-driven GBM progression. Genetic loss or locally antagonizing IL-1β/IL-1R1 leads to reduced MDM infiltration, diminished tumor growth, and reduced exhausted CD8+ T cells and thereby extends the survival of tumor-bearing mice. In contrast …

Development Of A Two-Dimensional Coupled Smoothed Particle Hydrodynamics Model And Its Application To Nonlinear Wave Simulations, Guixun Zhu, Jason Hughes, Siming Zheng, Deborah Greaves

School of Engineering, Computing and Mathematics

This paper presents a two dimensional two-way coupled model combining Smoothed Particle Hydrodynamics (SPH) based on the Navier–Stokes equations (NSE) and OceanWave3D based on the fully nonlinear potential flow theory (FNPT) in order to efficiently simulate non-linear waves and wave–structure interaction problems. The two models are strongly coupled in space and time domains using a fixed overlapping zone, wherein the information from both solvers is exchanged by relaxation functions. In the SPH model, an open relaxation boundary, which is implemented as open and relaxation zones, is used in the coupling region. Horizontal velocity and free surface elevation in the open …

Micro-Fibrillated Cellulose In Lignin–Phenol–Formaldehyde Adhesives For Plywood Production, Sheikh Ali Ahmed, Reza Hosseinpourpia, Stergios Adamopoulos

Michigan Tech Publications

Petrochemical-based phenol–formaldehyde (PF) adhesives are widely used in plywood production. To substitute phenol in the synthesis of PF adhesives, lignin can be added due to its structural similarity to phenol. Moreover, micro-fibrillated cellulose (MFC) can further enhance the bond performance, mechanical properties, and toughness of adhesive systems. Thus, the aim of this study was to evaluate the adhesion performance of lignin–PF (LPF) adhesives reinforced with MFC. In LPF formulations, three levels of MFC (0, 15, and 30 wt% based on the total solid content of adhesives) were added to the homogenous adhesive mixture. Three-layer plywood panels from birch (Betula pendula …

Selection Of Natural Surfactants For Possible Use In Improving Oil Recovery Of Carbonate Oil Reservoirs, Hiba Hachem Limam

Thesis/ Dissertation Defenses

Middle East petroleum industry is currently searching for the most suitable enhanced oil technique to improve the oil recovery from local oil reservoirs. The biggest challenge for the application of enhanced oil recovery (EOR) in the Middle East is the harsh environment (high salinity and temperature). Surfactant (synthetic or natural) is one of the enhanced oil recovery (EOR) major players considered for application in the Middle East. However, synthetic surfactants have several drawbacks, such as being economically unattractive and their high levels of toxicity. This study investigated the possible use of natural surfactant extracted from the leaves of three types …

Knowledge, Attitude, And Perception Of The General Public Towards The Impact Of Hemoglobinopathies On Pregnancy Outcomes: A Questionnaire-Based Study, Kumud Dhankhar, Kiran Dahiya, Shobha Chikkavaddaragudi Ramachandra, Akila Prashant

International Journal of Health and Allied Sciences

Background: Knowledge about hemoglobinopathies in the general public is unsatisfactory. Many couples are unaware of their carrier status and a child can be born with unexpected, serious hemoglobinopathies. Willingness to participate in screening programs can substantially help in bringing down the birth of children affected with hemoglobinopathies. To understand the knowledge, attitude, and perception of the general public on various hemoglobinopathies and their pregnancy outcomes we performed a questionnaire-based descriptive survey. Methods: After obtaining approval from the institutional ethics committee and validation by an expert panel we circulated a Google form consisting of 21 questions via WhatsApp which was made …

Risk Assessment In Discharge Process Using Pfmea Tool In A Multi-Specialty Hospital, Shalini ., Kanakavalli K. Kundury, H. Basavana Gowdappa

International Journal of Health and Allied Sciences

Introduction: ‘Quality’ is an inseparable component of healthcare. It focuses not only on care parameters but also in identifying the potential failures/ risks associated with the care process; thereby addressing them pro-actively before the occurrence of the loss. There are several quality tools available such as Process Failure Mode Effect Analysis (PFMEA) that helps in analyzing a process for identification of possible failures. This helps to find ways to avoid the occurrence of the failure or have a strategy to eliminate or minimize the risk. Thus, the current study was undertaken on identifying the risks involved in the discharge process …

Smallholder Farmer Resilience As A Pillar Of Climate-Smart Agriculture: A Review, Michael B. Madin Mr, Daniel Kweku B. Inkoom Professor, Charles A. Bamfo Jr

Journal of Environmental Sustainability

This systematic review synthesizes and assesses scientific literature publications (n=42), to identify and depict the focus of climate change adaptations and resilience research on smallholder farmers in the savannah ecological zone (SAZ). We found substantive studies providing evidence of climate impacts, with adverse consequences on both human and environmental systems. Adaptive actions are being employed to manage the changing conditions as response to climate impacts. Notably, most research efforts are currently restricted to impacts on adaptation, food security, and vulnerability, with a very rare focus on climate resilience and the effects of adaptive actions. Hence, the possible maladaptation outcomes, which …

Reading Perceptions Of Intrinsically Motivated High School Juniors, Judy Henning, Sherry R. Crow

Advanced Education Programs Faculty Publications

Studies show pleasure reading results in academic benefits but declines between elementary and secondary years. The question addressed is “what are the experiences in the lives of juniors (aged 16-18) that foster intrinsic motivation to read for pleasure?” Juniors from four mid-western U.S. schools with varied ethnic and socio-economic profiles were identified as highly and distinctly intrinsically motivated for pleasure reading. Interviews revealed participants excelled academically and had family members who were readers. They read to escape stress, occupy time, and investigate careers. Rarely reading for rewards, they were “opportunistic readers.” Relationships with librarians were important in finding good books …

Ritualized Affective Performances: Syriac Etiquette Guides And Systems Intelligence In Early Christian-Muslim Encounters, Luis Josué Salés

Scripps Faculty Publications and Research

In 2009, Michael Penn published a transcription and English translation of two Syriac texts, To the Rulers of the World (ܠܘܬ ܪ''ܝܫܢܐ ܕܥܠܡܐ) and Concerning the Entrance before a New Emir (ܕܡܥܠܬܐ ܨܝܕ ܐܡܝܪܐ ܚܕܬܐ). This essay proposes a new historiographical approach to these texts based on the concepts and theoretical apparatus of systems intelligence theory and affect theory. I show how these texts use key Islamic theological and cultural ideas that would affectively resonate with the Muslim authorities while remaining non-objectionable to the orthodoxy of the Assyrian Church of the East. Specifically, I argue that Christians sometimes sought to …
