Transgenerational Effects Of Stress On The Plasma Proteome Of A Marine Mammal, Emily Voelkner

University of the Pacific Theses and Dissertations

The physiological stress response enables animals to respond to changes in their environment, and is mediated by the hypothalamic-pituitary-adrenal (HPA) axis in mammals. Increased activation of the HPA axis by repeated stress during critical life stages like reproduction could affect fitness. Information about a stressor can be communicated to offspring via hormone signals prenatally, or postnatally via milk, and affect offspring development and stress reactivity. Experimentally activating the HPA axis by adrenocorticotropic hormone (ACTH) administration results in the synthesis of the major glucocorticoid hormone cortisol, which has well-studied far-reaching effects on growth, metabolism, and immunity. Beyond cortisol levels alone, biomarkers …

Embedded State Estimation For Optimization Of Cislunar Space Domain Awareness Constellation Design, Thomas Henry Clareson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The traffic in cislunar space is expected to increase over the coming years, leading to a higher likelihood of conjunction events among active satellites, orbital debris, and non-cooperative satellites. This increase necessitates enhanced space domain awareness (SDA) capabilities that include state estimation for targets of interest. Both Earth surface-based and space-based observation platforms in geosynchronous orbit or below face challenges such as range, exclusion, and occlusion that hinder observation. Motivated by the need to place space-based observers in the cislunar space regime to overcome these challenges, this paper proposes a cislunar SDA constellation design and analysis framework that integrates state …

State Estimation And Economic Analysis For Electrochemical Sensor-Based Corrosion Monitoring, Chandra Sekhar Somayajula

Graduate Theses, Dissertations, and Problem Reports (ETD)

Coal is currently the third-largest source of electricity production in the U.S. However, renewables are projected to be the primary source of electricity production in the future. Though coal-fired power plants (CFPPs) are rapidly retiring in the U.S., many CFPPs worldwide are expected to stay operational for a while due to factors like easy and cheap access to comparatively inexpensive coal. Therefore, non-renewable sources like coal are still expected to be prevalent and be used to ensure the stability of the electric grid in the foreseeable future. The existing coal-fired power plants generally designed to operate at base-loaded conditions are …

The Picture Of (Mental) Health: A Photovoice, Narrative Inquiry, And Critical Participatory Action Approach To Music Major Mental Wellness, Paige Zalman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Higher education is experiencing a mental health epidemic (Venit, 2022). There is unprecedented student demand for psychological services that colleges are unable to meet (Lipson et al., 2019a), leading to high rates of mental illness-related attrition (Koch et al., 2018). Two groups of students at particularly high risk of mental illness-related attrition are students with historically marginalized identities, whether by race, gender, income, or another factor (Eisenberg et al., 2013), and music majors, a group that has been shown to have greater rates of mental illness than students in other majors (Lipson et al., 2016; Spahn et al., 2004). While …

Building Better Biofuel Crops: A Field Evaluation Of Transgenic Populus Modified To Improve Feedstock Performance For Bioenergy Use, Molli Elisabeth Coombs

Graduate Theses, Dissertations, and Problem Reports (ETD)

A transition away from fossil fuel use is necessary for the future of energy production, and biofuels are a renewable energy option that can mitigate the impacts of fossil fuels through lowered carbon emissions and possible carbon sequestration. In order to successfully compete with fossil fuels, the production of biofuels must be sustainable and cost effective. Populus species are a biofuel crop used for bioenergy conversion from lignocellulosic biomass that have been proposed for use in feedstock plantations on marginal lands, which would avoid competition with agricultural production. Two challenges of feedstock production being faced are recalcitrance to chemical processing, …

Undue Limitations In The Section 10(B) Purchaser-Seller Requirement, Marc I. Steinberg, Antonio R. Partida

Faculty Journal Articles and Book Chapters

This article considers different applications of the Purchaser-Seller Rule that a plaintiff must satisfy to bring a Section 10(b) and Rule 10b-5 private action. The history and development of the Purchaser-Seller Rule under Supreme Court and lower federal court jurisprudence is considered, with emphasis on recent case law unduly constricting this Rule. In particular, the Second Circuit’s restrictions on Section 10(b) standing are addressed, focusing on that appellate court’s decision in Frutarom which adhered to an overly formulaic approach to Section 10(b) standing that is out of line with prior Second Circuit and Supreme Court precedent. The article then considers …

Characterization Of The Acquisition Parameters Of A Submersible Gamma-Ray Computed Tomography System, Zhongmin Jin

Doctoral Dissertations

"The purpose of this work is to study a component of a submersible gamma-ray computed tomography (CT) system used in the non-destructive testing of irradiated nuclear fuels. The first section of this study proposes two acceleration approaches for rapidly modeling a transmission-type gamma-ray tomography system. The first relies on Monte Carlo simulations with a monodirectionally biased source sampled from a sub-volume of the whole source volume. This method estimates the real count rate using analytical correction factors. The second way of acceleration is based on deterministic calculations that use the Beer-Lambert law and detector response characteristics. It shows that both …

Sensing, Knowing, And Making Water Quality Along Marikina River In The Philippines, Gideon Lasco, Anita Hardon

Development Studies Faculty Publications

Water quality is a major concern around the world, but assessments of quality often privilege producers, regulators and experts over consumers. With water supplies and sources constantly in flux, how do ordinary people experience and “sense” quality? How do they define “good” or “good enough” water, and what practices do they engage in to “make” good water? In this article, we attend to these questions by presenting findings from an open-ended qualitative study carried out along the Marikina River, Manila, the Philippines – a waterway that courses from rural and mountainous villages to highly urbanized communities. First, we describe the …

Herein, the defect structure of the best performing nano catalyst in the series are further explored, Nd₂Ce₂O₇, with a combination of neutron diffraction and neutron pair distribution function analysis. It is …

Geographies Of Storage, Sayd Randle

Research Collection College of Integrative Studies

Resource storage has long played a key role in the production of socio-ecological arrangements and economic relations. Even so, storage as a concept has remained somewhat marginal within geographical scholarship, often obscured by an analytical focus on the dynamics of movement. Reviewing recent works from geography, science and technology studies, and anthropology that center sites and practices of storage, this essay elaborates the diverse ways in which storage arrangements mediate resource circulation and the production of space. This literature demonstrates that thinking systematically with storage can illuminate a range of novel temporal, material, and value entanglements in-the-making, pointing to potentially …

Experimental Evaluation Of Thermal Adaptation And Transient Thermal Comfort In A Tropical Mixed-Mode Ventilation Context, Yue Lei, Duygu Zeynep Tekler, Sicheng Zhan, Clayton Miller, Adrian Chong

Research Collection College of Integrative Studies

Mixed-mode ventilation offers a promising solution for achieving comfortable indoor environments in an energy-efficient manner. However, in the tropics, characterized by a year-round hot and humid climate, opportunities for natural ventilation (NV) are typically limited to specific hours, necessitating operational mode switches on an intraday basis. Much of the thermal comfort research on mixed-mode ventilation relies either on cross-sectional data collected from different subjects or longitudinal data spanning a few seasons. This raises an open question: Can occupants thermally adapt when switching between NV and air-conditioning (AC) modes within a single day? To address the gap, our experimental study engaged …

Highly Dipole-Parallel Aligned Nonlinear Optical Organic Molecular Crystalline Materials: Rational Design, Experimental And Theoretical Studies Of Supramolecular Structures And Non-Covalent Interactions, Harmeet Singh Bhoday

Doctoral Dissertations

Highly dipole-parallel aligned donor-acceptor substituted organic molecules are attractive for a wide array of applications, including nonlinear optics. However, only a limited number of crystals are known to adopt polar non-centrosymmetric space groups. The concepts guiding the fabrication of these polar materials have been described. The study focused on unsymmetrical donor-acceptor substituted azines and butadiene's. An improved design over (MeO, Y)-azines led to the realization of three crystals perfectly aligned in dipole parallel orientation for (PhO, Y)-azines with Y = Cl, Br, I, and one nearly perfectly aligned crystal for Y = F (Paper I). The unique bonding properties associated …

Captain Hook To Space Crook: Towards A Convention On The Suppression Of Space Piracy, Vinita Singh

Fordham International Law Journal

While the commercial future of outer space endeavors is bright, parallels between outer space and the high seas and advances in modern technology suggest Space Piracy will become a real and serious peril to States and their nationals. Because preexisting international law does not adequately empower States to tackle this threat, States must proactively consider adoption of a Convention on the Suppression of Space Piracy. Based on the strengths and weaknesses of applicable law of the sea and criminal aviation law, this work offers draft language for two key provisions of this Convention—a definition of “Space Piracy” and a delineation …
