It Shucks To Be Inbred: Effects Of Small Population Sizes On Genomic Diversity Of Hatchery Reared Olympia Oysters (Ostrea Lurida), Anna S. Heasley

Master's Theses

Olympia oysters (Ostrea lurida), critical members of estuarine ecosystems along the California Current Ecosystem (CCE), have faced significant population declines due to historical overfishing and habitat deterioration. Today, managers from multiple estuaries across the CCE are focusing on conservation aquaculture breeding efforts to aid in restoration; however, the genetic implications of these efforts remain unexplored. As with other Ostrea spp, Olympia oysters have a viviparous reproductive strategy that creates unique challenges for aquaculture-mediated restoration. This study evaluates the genetic impact of current captive breeding practices on Olympia oyster cohorts produced in three California estuaries: Elkhorn Slough (EHS), Morro Bay (MB), …

Environmental Science and Management Faculty Publications and Presentations

Understanding how water moves through a watershed is one of the most fundamental yet often complicated aspects of hydrology, especially in urban areas. Urban infrastructure and water management alter natural hydrological pathways in developed watersheds, which can violate assumptions of a watershed approach to ecosystem science. We focus on two aspects of urban landscapes that often create challenges to model watershed processes within and among urban areas: (1) accurate delineation of urban flow paths and (2) consistent characterisation of the urban landscape within and among cities. Here, we describe these challenges and identify how certain components of these challenges can …

Copper Oxide Nanoparticles As Delivery Vehicles For Different Pt (Ii)-Drugs: Experimental And Theoretical Evaluation, Shahdan Abdelkareem

Theses and Dissertations

Platinum(II)-based chemotherapeutic agents such as cisplatin, oxaliplatin, and nedaplatin are mainstays in the treatment of a wide range of solid tumors, yet their clinical application is severely restricted by rapid degradation, poor bioavailability, and dose-limiting side effects. These challenges arise in part from the drugs’ susceptibility to premature hydrolysis, off-target interactions in the bloodstream, and degradation in the gastrointestinal tract, which collectively limit their ability to reach and act on tumor cells. To address these limitations, we explored the use of copper(II) oxide nanoparticles (CuO NPs) as nanocarriers for platinum(II) drugs, aiming to enhance drug stability, loading, and controlled release. …

McNair Summer Research Program

In response to the ongoing catastrophic wildfires in the U.S., especially the West Coast region, the State of California is proactively implementing the first multi-faceted legislative and regulatory framework to enhance wildfire resiliency.

During a disaster, embers are the most important contributors to wildfire, and can dictate whether homes ignite or not. Given their potent ignition source, their capacity to travel for miles, researchers have concluded that wind-blown embers are the leading cause of destruction during wildfires. Simultaneously, the purpose of the 2025 building codes is to strengthen construction methods, requiring the use of rated structural materials, such as sheathing, …

Watching The Clock: Time-Tracking And The Erosion Of Privacy And Dignity At Work, Tammy Katsabian

Comparative Labor Law & Policy Journal

This article examines the rise of time-tracking technologies as a dominant form of digital workplace surveillance and their implications for workers’ privacy and dignity. Often framed as neutral tools for enhancing productivity, these systems embed continuous algorithmic oversight into daily work routines, intensifying managerial control and reshaping the employment relationship. Drawing on legal, philosophical, and socio-technical scholarship, the article argues that privacy and dignity are mutually reinforcing values, both of which are undermined by pervasive surveillance practices. Privacy is not treated here as a waivable entitlement grounded in individual consent, but rather as a structural safeguard that protects autonomy and …

Performance Mapping And Weighting For The Evapotranspiration Models Of The Openet Ensemble, M. Reitz, J. M. Volk, T. Ott, M. Anderson, G. B. Senay, F. Melton, A. Kilic, R. Allen, Joshua B. Fisher, A. Ruhoff, A. J. Purdy, J. Huntington

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Evapotranspiration (ET) accounts for the majority of water available from precipitation in the terrestrial water cycle, and improvements to the accuracy, resolution, and coverage of ET data can enhance hydrologic models and assessments. The OpenET collaboration of six remotely sensed ET modeling teams has demonstrated that an ensemble approach to ET estimation generally provides improved accuracy relative to individual ensemble members. The performance of individual models has been shown to vary by land cover type and climate zone, but a thorough study of the variables that influence model performance differences has not yet been conducted. In this paper, we model …

Visio Dei, Vision Pro: Beatific Vision And Technological Singularity, John Paul Arceno

Liberty Theological Review

This paper offers a retrieval of the classical Christian theology of beatific vision. The reason behind this is the challenges posed by the progress of digital technology, including Artificial Intelligence, Virtual Reality, and robotics, which are prevalent today. This rapid progress somehow threatens the classical view of beatific vision with its version of technological singularity. Hence, the retrieval of the beatific vision, which is grounded in divine ontology, is much needed. The paper is divided into three parts: (1) Visio Dei, which discusses the doctrine of beatific vision, (2) Vision Pro, which discusses technological singularity, and (3) conclusion, which …

Deuteronomy And Ane Worldview Apologetics In A Postmodern Context, Eric Mcconnell

Liberty Theological Review

Postmodern Christianity seeks to divorce the miraculous and divine elements from Scripture and shape biblical morality in a way that relates to postmodern culture. Responding to Postmodern Christianity’s errors requires a consistent literal hermeneutic in one’s exegesis and a sound biblical framework in one’s apologetic method. The message of Deuteronomy presents a possible paradigm for this task, as its contents present a culturally-relevant polemic against false maxims and errant religion that God’s people faced within their own milieu. Moses’ polemic in Deuteronomy 4 presents a paradigm that would be employed by the prophets to counter the faulty syncretistic worldview that …

Shimmering Mirage Or A Promised Land? Climate Change, Agriculture, And Internal Migration In Sabha, Jordan, Tyler J. Rak

Capstone Collection

Given the rapidly shifting climate, high vulnerability, and low adaptability to climate related changes that rural areas face, this study highlights the complex relationship between climate change -- especially water scarcity -- agriculture, and internal migration in rural Jordan. I predict that if water scarcity is present and climate changes are occurring, they will undercut the rural agriculture sector which could contribute to rural out-migration. To study this relationship, I conducted a case study in Sabha, a small rural community in the Northern Badia of Jordan. Data was gathered by engaging in semi-structured interviews with current community members in Sabha …

Retracted: Mathematical Properties And Simulations Of The Neutrosophic Gompertz-Inverse Burr-X Distribution With Application To Under-Five Mortality, Mustafa Hassan Jumaa, Asmaa S. Qaddoori, Sara A. Khalaf, Nooruldeen A. Noori, Mundher A. Khaleel

Iraqi Journal for Computer Science and Mathematics

Despite significant progress in the development of statistical distributions, there remain clear gaps in modelling complex datasets, such as those involving uncertainty or requiring flexible representations of multidimensional variables. This study introduces a new distribution the Neutrosophic Gompertz-Inverse Burr-X (NGoIB-X) distribution to address these challenges. The model is based on the Neutrosophic Gompertz family (NGo-G), which itself employs the T-X method in its formulation. Characterised by four Neutrosophic parameters and a Neutrosophic random variable, the NGoIB-X distribution offers enhanced flexibility for representing and analysing uncertain data. The theoretical properties of the NGoIB-X distribution are explored, including its Neutrosophic probability density …

A New Lightweight Encryption Method Based On The Dna-Rc4 Substitution For Resource-Constrained Iot Devices, Athraa J. H. Witwit, Ahmed Fanfakh, Ali Kadhum Idrees

Iraqi Journal for Computer Science and Mathematics

Technology's impact on daily life necessitates increased data protection. Cryptographic systems improve security, ensuring confidentiality and legitimacy of Internet of Things systems. However, resource-constrained devices face challenges like memory, battery life, processing power, and small size. In light of this, lightweight cryptography (LWC) provides techniques specifically tailored to the constraints of resource-constrained Internet of Things devices. However, the presence of a fixed S-Box in some LWC algorithms, such as Advanced Encryption Standard, or the absence of one in others, such as Speck and Tiny Encryption Algorithm, renders them more susceptible to attacks. In this paper, we suggest a new lightweight …

Hybrid Organic–Inorganic Corrosion Inhibitors: Bridging Performance And Eco-Safety, Hasan M. Luaibi, Saja S. Al-Tweel

AUIQ Technical Engineering Science

Corrosion leads to global economic losses exceeding $2.5 trillion annually and accounts for up to 30% of infrastructure failures. Conventional corrosion inhibitors face limitations such as aquatic toxicity (LC50 <100 mg/L), moderate efficiencies (65–82%), and poor long-term durability (<500 hours). This review critically evaluates hybrid organic–inorganic corrosion inhibitors, focusing on their composition, mechanisms, performance metrics, and eco-safety. Hybrid systems comprising organic molecules integrated with inorganic matrices like sol–gel networks, nanocomposites, and layered double hydroxides (LDHs) demonstrate enhanced functionality through barrier effects, self-healing, and controlled release. These materials achieve inhibition efficiencies of 88–98.5%, outperforming conventional systems by 18–35%. Sol–gel coatings protect carbon steel at 92–98% efficiency in 3.5% NaCl, while LDHs sustain 94–97% protection over 1200–1500 hours. Nanocomposites reduce corrosion rates from 0.95 mm/year to 0.002–0.004 mm/year. Electrochemical techniques (EIS, PDP) show increased charge transfer resistance (500–2500 Ω·cm²) and coating resistance up to 10⁸ Ω·cm². Surface analysis reveals smoother films (Ra = 15–35 nm), higher contact angles (95–125°), and adhesion strengths of 12–18 MPa. Case studies report 90–96% protection in marine settings, 88–94% in acidic media, and over 92% under atmospheric conditions. Durability tests confirm >90% efficiency after 1000 hours, significantly higher than the <60% for conventional coatings. Overall, hybrid inhibitors offer a high-performance, eco-conscious alternative for corrosion control, combining efficiency, environmental safety, and scalability. Their superior metrics and adaptability position them as next-generation solutions for diverse industrial applications.
