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 …

The Challenges Of Minoritized Contingent Faculty In Higher Education, Edna Chun, Alvin Evans

Navigating Careers in Higher Education Series

The Challenges of Minoritized Contingent Faculty in Higher Education offers a probing and unvarnished look at the employment challenges of these faculty members in four-year institutions. With dramatic shifts in the faculty workforce and nearly three-quarters of instructional positions in United States institutions now off the tenure track, contingent faculty have become the essential, frontline workers of higher education. Remarkably little research attention has focused on the experiences of minoritized contingent faculty in this new academic underclass. Based on in-depth interviews coupled with extensive research, the book highlights the double marginalization that can occur due to secondary employment status in …

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 …

Expanding Community Capacity: Empowering Non-Clinical Gatekeepers To Respond To Persons In Suicide Crisis, Michael J. Polacek

Dissertations

Suicide is a leading cause of death and rates continue to rise despite focused efforts by policymakers. A family member, friend, or peer often plays a key role in initially identifying, rescuing, and then supporting ongoing recovery efforts of someone at risk for suicide. Preparation is provided through suicide prevention gatekeeper training such as QPR, yet this partner of direct professional service providers often lacks adequate support to effectively perform gatekeeper behaviors leading to the research question, "Does virtual café support effective gatekeeper behaviors?" The project uses a mixed-method approach to determine if a focused discussion group using The World …

Urinary Tract Infections: A Review Of The Current Diagnostics Landscape, Braith Grey, Mathew Upton, Lovleen Tina Joshi

School of Biomedical Sciences

Urinary tract infections are the most common bacterial infections worldwide. Infections can range from mild, recurrent (rUTI) to complicated (cUTIs), and are predominantly caused by uropathogenic Escherichia coli (UPEC). Antibiotic therapy is important to tackle infection; however, with the continued emergence of antibiotic resistance there is an urgent need to monitor the use of effective antibiotics through better stewardship measures. Currently, clinical diagnosis of UTIs relies on empiric methods supported by laboratory testing including cellular analysis (of both human and bacterial cells), dipstick analysis and phenotypic culture. Therefore, development of novel, sensitive and specific diagnostics is an important means to …

Experimental Study Of Surfactants’ Performance For Suppressing Coal Dust With Respirable Size, Zidong Zhao, Ping Chang, Guang Xu, Apurna Ghosh, Ramakrishna Morla

Mining Engineering Faculty Research & Creative Works

Long-term exposure to coal dust can lead to severe health problems in coal workers, including Coal Workers' Pneumoconiosis, making effective control of coal dust in underground mines essential. Water spraying is a widely used method for controlling coal dust, and adding surfactants can remarkably enhance its effectiveness. While previous studies have examined the influences of different coal particle sizes on surfactant performance, they have primarily focused on inhalable dust with sizes less than 100 µm. The impact of finer particle sizes, such as respirable dust with sizes less than 10 µm, remains inconclusive. This study aims to investigate the effects …

Simulations Of Zero Boiloff, Densification, And Solidification In A Large-Scale Liquid Hydrogen Tank, Colin Philip Mahony

Electronic Theses and Dissertations Archive

The current research utilizes an Energy of Fluid (EOF) approach to develop a finite volume-based Computation Fluid Dynamic (CFD) model to create a benchmark simulation of the densification of liquid hydrogen (LH2) in an experimental Integrated Refrigeration and Storage (IRAS) tank at the Kennedy Space Center (KSC). The computational code will incorporate a commercial pressure-based model with User Defined Functions (UDF) to implement the EOF model. The enhanced model will solve the energy equation in terms of internal energy and provide temperature and pressure calculations for a given tank geometry. Specifically, a convection term will be added to an already …

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 …

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 …

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, Katsuhiro Yoshimura, Xiaodan Yao, Ruiping Wang, Ailing W Scott, Melissa Pool Pizzi, Jingjing Wu, Lang Ma, George A Calin, Samir Hanash, Linghua Wang, Michael Curran, Jaffer A Ajani

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 …

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 …

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 …
