Experimental And Numerical Analysis Of A Sustainable Farming Compartment With Evaporative Cooling System, M. Sina Mousavi, Siamak Mirfendereski, Jae Sung Park, Jongwan Eun

Department of Civil and Environmental Engineering: Faculty Publications

The United Arab Emirates (UAE) relies on groundwater as well as desalinated water which are very expensive and energy-concentrated. Despite the lack of water resources, only 54% of wastewater was recycled in the UAE in 2016. In this study, a Sustainable Farming Compartment (SFC) with an evaporative cooling system is investigated as an alternative to reusing wastewater and the optimal design is identified experimentally and numerically. First, the applicability of the SFC was examined to reduce the ambient temperature in the system. A prototype SFC was tested in the environmentally constrained laboratory and field site considering an extreme climate condition …

Impact Of The Human Footprint On Anthropogenic Mortality Of North American Reptiles, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

United States Department of Agriculture Wildlife Services: Staff Publications

Human activities frequently result in reptile mortality, but how direct anthropogenic mortality compares to natural morality has not been thoroughly investigated. There has also been a limited examination of how anthropogenic reptile mortality changes as a function of the human footprint. We conducted a synthesis of causespecific North American reptile mortality studies based on telemetry, documenting 550 mortalities of known cause among 2461 monitored individuals in 57 studies. Overall 78% of mortality was the result of direct natural causes, whereas 22% was directly caused by humans. The single largest source of mortality was predation, accounting for 62% of mortality overall. …

An Investigation Of High-Speed Consolidation And Repair Of Carbon Fiber - Epoxy Composites Through Ultrasonic Welding, David A. Hoskins

LSU Master's Theses

Adhesive repair of carbon fiber composite structures is commonly done on damaged structures to extend the service life. This method requires careful preparation of the damaged surface with intricate steps to ensure good bonding between the repair patch and the parent structure by means of an adhesive film. As with many forms of composite manufacturing, it is required to perform vacuum bagging, debulking, and a heated cure depending on the resin. All these steps make the repair process costly and time consuming.

In this present work, an alternative method of repair is investigated which explores the experimental feasibility of using …

Reinterpreting The Tectonic Model Of The Southern Part Of The Taconic Orogeny Through A Provenance Study Of Late Ordovician Sandstones, Juan Carlos Guerrero

LSU Master's Theses

A provenance study of quartz arenites that stratigraphically are closely associated with major Ordovician K-bentonites has been conducted in order to further our understanding of the tectonic setting of eastern Laurentia during the Late Ordovician. Using laser ablation ICP-MS, detrital zircons separated from Ordovician sandstone samples in the southeastern Appalachian Mountains (Virginia to Alabama) were dated using U-Pb geochronology. Analytical results show three dominate age ranges for the zircons from these sandstones: ~440-490 Ma, ~900-1300 Ma, and ~1300-1500 Ma. In addition, some zircon ages grouped into older ranges of ~1600-1800 Ma, ~1800-1900 Ma, and ~2600-2800 Ma. Zircon ages from ~900-2800 …

Sandy Dredge Pit Sedimentation – Characteristics And Processes In Caminada Borrow Area, Ship Shoal, Louisiana Shelf, Usa, Zehao Xue

LSU Master's Theses

Mississippi River Deltaic Plain’s barrier islands are undergoing rapid disintegration due to high rates of subsidence and a deficit in coastal sediment supply. To mitigate for barrier island land loss, Louisiana has implemented a restoration program that supplements coastal sediment deficits by introducing sand from outside of the active coastal system. Ship Shoal is an inner-shelf submarine shoal with large amounts of restoration quality sand that was dredged in 2013-2016 for the Caminada Headland Restoration Project in central Louisiana, USA.

Vibracore samples (1.5 - 3.5 m deep) collected in 2017 and 2018 in Caminada Borrow Area revealed new silts and …

Anaerobic Dechlorination Of Polychlorinated Dibenzo-P-Dioxins In Passaic River Sediments, Donna E. Fennell

Sustainability Seminar Series

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) are persistent, bioaccumulative and toxic pollutants found in the environment. The Passaic River in New Jersey is highly contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TeCDD), one of the most toxic of the PCDD/F congeners. Our on-going research at Rutgers is intended to better understand PCDD/F dichlorination by anaerobic organohalide respiring bacteria (OHRB). Results will be presented from various anaerobic enrichment cultures (including from the Passaic River) enriched on alternate organohalides such as trichloroethene and dichlorobenzene to stimulate OHRB. Activity against three PCDD congeners: 1,2,3,4-tetrachlorodibenzo-p-dioxin, a well-studied model PCDD congener; 2,3,7,8-TeCDD; and 2,7-dichlorodibenzo-p-dioxin, a potential metabolite of 2,3,7,8- TeCDD, …

Building A Stem Mentoring Program In An Economically Disadvantaged Rural Community, Seema Rivera, Jennifer M. Knack, Kathleen Kavanagh, Joshua Thomas, Mary Margaret Small, Michael Ramsdell

Journal of Educational Research and Practice

Rural, economically disadvantaged communities face a bigger challenge than urban communities in recruiting and retaining high school (HS) students in science, technology, engineering, and mathematics (STEM) because many of these students do not have access to high-quality STEM opportunities. In this article, we describe a mentoring program we developed as part of a larger New York State education grant. This program was implemented in a rural community to connect undergraduate STEM students with HS students to increase HS students’ interest in these fields. In this program, HS students visited colleges, explored their interests in STEM, and learned about opportunities available …

Context. Brown dwarfs (BD) are substellar objects intermediate between planets and stars with masses of ~13–80 M_J. While isolated BDs are most likely produced by gravitational collapse in molecular clouds down to masses of a few M_J, a non-negligible fraction of low-mass companions might be formed through the planet-formation channel in protoplanetary discs. The upper mass limit of objects formed within discs is still observationally unknown, the main reason being the strong dearth of BD companions at orbital periods shorter than 10 yr, also known as the BD desert.

Aims. To address this question, we aim …

The Status Of Women On Utah State Boards & Commissions: A 2019 Update, Susan R. Madsen, Megan Roper

Marketing and Strategy Faculty Publications

Research shows that organizations will increasingly thrive when both men and women hold leadership roles. Gender inclusivity benefits not only businesses, but also entities such as churches, state legislatures, city councils, state governments, and state and local boards and commissions. Studies have shown that there are numerous benefits to attracting, retaining, promoting, and empowering women within organizations and entities. These benefits are discussed at length in a previous brief titled “Why Do We Need More Women Leaders in Utah?”2More specifically, research demonstrates the need for the government—and democratic governance processes in general—to reflect gender diversity accurately within its constituency at …

Social And Emotional Competencies And Science Performance In The Usa: Evidence From Pisa 2015, Guillermo Montes

Education Faculty/Staff Publications

This paper asks whether students with different socioemotional learning (SEL) profiles perform differently in science. Using latent class analysis, we found three distinct groups of students: a majority of students who are relatively unmotivated and isolated, a sizeable group of students who are strong co-operators, and a relatively small group of students who are highly motivated and enjoy science, but do not value cooperation. After controlling for student and family covariates, as well as classroom, teaching and school leadership and institutional variables, the highly motivated, individualist group substantially outperformed the isolated group, with the co-operator group having intermediate performance. These …

Developing And Optimizing Shrub Parameters Representing Sagebrush (Artemisia Spp.) Ecosystems In The Northern Great Basin Using The Ecosystem Demography (Edv2.2) Model, Karun Pandit, Hamid Dashti, Nancy F. Glenn, Alejandro N. Flores

Geosciences Faculty Publications and Presentations

Ecosystem dynamic models are useful for understanding ecosystem characteristics over time and space because of their efficiency over direct field measurements and applicability to broad spatial extents. Their application, however, is challenging due to internal model uncertainties and complexities arising from distinct qualities of the ecosystems being analyzed. The sagebrush-steppe ecosystem in western North America, for example, has substantial spatial and temporal heterogeneity as well as variability due to anthropogenic disturbance, invasive species, climate change, and altered fire regimes, which collectively make modeling dynamic ecosystem processes difficult. Ecosystem Demography (EDv2.2) is a robust ecosystem dynamic model, initially developed for tropical …

Preparing For Life In A Digital World: The Iea International Computer And Information Literacy Study 2018 International Report, Julian Fraillon, John Ainley, Wolfram Schulz, Tim Friedman, Daniel Duckworth

ICT - Digital Literacy

The second cycle of ICILS in 2018 (ICILS 2018) continued to investigate students’ computer and information literacy (CIL) and also investigated students’ computational thinking (CT). This dimension involves conceptualising problems (through algorithmic or systems thinking) and operationalising solutions (creating, implementing, and evaluating computer-based responses to problems). The inclusion of CT as an option in ICILS 2018 reflects recent interest by educators, researchers, and policymakers in the value of CT in schooling. ICILS 2018 studied how these components of digital competence related to each other and to the school and out-of-school contexts that support learning with and about computer technology. This …

How Do Us College Students' Sense Of Life Purpose Relate To Their Emotional Expectations Toward Community Work In Service-Learning Courses?, Seana Moran, Randi L. Garcia

Psychology: Faculty Publications

INTRODUCTION: Few studies consider how purpose in life predicts emotions related to community service in college courses even though a purpose in life, a “compass” for finding opportunities to make meaningful prosocial contributions, should motivate students to serve. METHOD: Multilevel structural equation modeling estimated direct and indirect effects of survey responses regarding students’ past service experience, sense of purpose, and searching for purpose on their emotional expectations for service-learning before starting. RESULTS: Controlling for age, gender, extrinsic motivation, and characteristics of universities and courses, students’ past service experience and two purpose variables positively related to expected positive emotions toward service …

Phasor Measurement Unit Data-Based Steady State And Dynamic Model Estimation, Anas Almunif

USF Tampa Graduate Theses and Dissertations

Phasor measurement units (PMUs) have been put into power grid for real-time monitoring. This research investigates the PMU data for steady state estimation and dynamic model estimation. It focuses on three main research areas to enhance the security of the power system monitoring. First, optimal PMU placement (OPP) problem is developed to minimize the number of PMUs required for the system to be completely observable using mixed integer linear programming and nonlinear programming. Second, PMU measurements are ranked for oscillation monitoring based on two approaches: oscillation mode observability and Prony analysis. Further, the principles, multi-channel data handling, and noise resilience …

Plasmonic Stimulation Of Electrically Excitable Biological Cells, Parveen Bazard, Robert Dana Frisina, Joseph Paul Walton, Venkat Rama Bhethanabotla

USF Patents

A novel method to stimulate electrically active biological cells using visible wavelength light and metallic nanoparticles possessing plasmonic properties is presented herein. Using this technology, prosthetic devices such as cochlear and retinal implants and cardiac pacemakers can be developed to have superior properties as compared to the currently utilized electrical stimulation designs. These properties include improved spatial resolution; less or non-invasive devices; and higher fidelity of transduction. An additional advantage of using visible light wavelengths is the avoidance of unwanted heating of surrounding tissue that occurs with infrared stimulation.

Weaponizing Radioactive Medical Waste - The Looming Threat, Shreekumar Menon, Vagish Kumar L.S.

International Journal of Nuclear Security

Across the globe, use of radioactive substances for medical treatment, by hospitals has resulted in generation of toxic wastes on a large scale. Disposal of these wastes are being entrusted to waste disposal vendors. Environmental concerns, pressures, restrictions and high labor costs, compel these vendors to dump these wastes in third world countries, where enforcement and awareness are substantially low. Unrestricted access to these waste dumps is an open invitation to terror organizations to extract toxic substances and fabricate crude dirty bombs to threaten public safety, and cause low-level contamination of sensitive installations. It is therefore imperative to create an …

Towards Overcoming The Curse Of Dimensionality: The Third-Order Adjoint Method For Sensitivity Analysis Of Response-Coupled Linear Forward/Adjoint Systems, Uncertainty Quantification And Predictive Modeling With Applications To Nuclear Energy Systems, Dan Gabriel Cacuci

Faculty Publications

This work presents the Third-Order Adjoint Sensitivity Analysis Methodology (3rd-ASAM) for response-coupled forward and adjoint linear systems. The 3rd-ASAM enables the efficient computation of the exact expressions of the 3rd-order functional derivatives (“sensitivities”) of a general system response, which depends on both the forward and adjoint state functions, with respect to all of the parameters underlying the respective forward and adjoint systems. Such responses are often encountered when representing mathematically detector responses and reaction rates in reactor physics problems. The 3rd-ASAM extends the 2nd-ASAM in the quest to overcome the “curse of dimensionality” in sensitivity analysis, uncertainty quantification and predictive …

Comprehensive Second-Order Adjoint Sensitivity Analysis Methodology (2nd-Asam) Applied To A Subcritical Experimental Reactor Physics Benchmark: I. Effects Of Imprecisely Known Microscopic Total And Capture Cross Sections, Daniel Gabriel Cacuci, Ruixian Fang, Jeffrey A. Favorite

Faculty Publications

The subcritical polyethylene-reflected plutonium (PERP) metal fundamental physics benchmark, which is included in the Nuclear Energy Agency (NEA) International Criticality Safety Benchmark Evaluation Project (ICSBEP) Handbook, has been selected to serve as a paradigm illustrative reactor physics system for the application of the Second-Order Adjoint Sensitivity Analysis Methodology (2nd-ASAM) that was developed by Cacuci. The 2nd-ASAM enables the exhaustive deterministic computation of the exact values of the 1st-order and 2nd-order sensitivities of a system response to the parameters underlying the respective system. The PERP benchmark is numerically modeled in this work by using the deterministic multigroup neutron transport equation discretized …
