Finite Element Investigation Of Blast Load Responses In Nuclear Power Plant Containment Structures, Janak Raj Awasthi

Civil Engineering ETDs

Some significant incidents like the Chernobyl disaster (1986), the Fukushima Daiichi hydrogen explosion (2011), and some frequent military and terror threats to the nuclear Power plant structures have led to studying the capacity of power plant structures to withstand blast loadings. From this research, even one-third of the loss of the coolant is enough to damage the power plant structure. Crack starts from the wall and propagates toward the top of the dome and the foundation. The external blast shows high damage symptoms near the foundation area. Most of the steel members, including the rebars, Liner, and Tendons, showed high …

Nursing Turnover Based On Age, Race, And Gender In Community Hospitals In Michigan, Laura Lawhorn

Walden Dissertations and Doctoral Studies

Hospitals struggle to maintain nursing staff to meet patient needs for a population that requires continuous care and experiences multiple illnesses. The purpose of this quantitative study was to investigate the variations in reasons for leaving the nursing profession (dependent variable) based on age, race, and gender (independent variables) within community hospitals in Michigan. The theoretical framework for this study was the Nursing Neuman Systems Model, which posits that nursing comprises four key components: environment, individual, nursing practice, and health. A correlational research design was utilized to address the research question and analyze the relationships between the variables. The secondary …

Lessons In Longevity From Blood Stem Cells Under Protein Stress, André Catic

Center on Aging Staff Publications

Blood stem cells are among the body's longest-living cells despite being highly vulnerable to proteotoxic damage, which accelerates their aging. To maintain protein homeostasis (proteostasis), hematopoietic stem cells (HSCs) employ mechanisms such as reduced translation rates, high chaperone activity, autophagy, and selective protein degradation. These strategies mitigate protein misfolding, maintain quiescence, and preserve regenerative potential. Disruptions in proteostasis can lead to the elimination of impaired HSCs through differentiation or apoptosis, ensuring the integrity of the stem cell pool. Due to the systemic impact of the blood on aging and its experimental and clinical accessibility, investigating HSC proteostasis provides insights into …

School of Biological and Marine Sciences

Invasive plant species pose an increasing threat to mangroves globally. This study assessed the impact of Paspalum vaginatum invasion on carbon loss and early recovery following four years of restoration in a mangrove forest with Rhizophora racemosa in Benin. Organic carbon was quantified in the total biomass, including both aboveground and belowground components, as well as in the soil to a depth of −50 cm. In addition, soil gas fluxes of CO ₂, CH ₄, and N ₂O were measured. Three sites were evaluated: a conserved mangrove, a site degraded by P. vaginatum, and the same site …

Effects Of The Gut Microbiota On Placental Angiogenesis And Intrauterine Growth In Gnotobiotic Mice, Reyan Coskun, Zenan L Chang, Athziri Marcial Rodríguez, Haoxin Liu, Jiye Cheng, Yael Alippe, Michael S Diamond, Jeffrey I Gordon

2020-Current year OA Pubs

Environmental causes of intrauterine growth restriction (IUGR) remain poorly characterized. Here, we compare germ-free (GF) and conventionally raised (CONV-R) mice to assess the effects of the gut microbiota on placental/fetal development at embryonic day (E)11.5 (end of placentation) and E17.5 (near term). Pregnancy- and microbiota-associated changes in gene expression occur along the gut, including those related to angiogenesis, while bacterial composition and fermentation activity remain stable. Placental weights at E11.5 and fetal weights at E17.5 are significantly reduced in GF animals. Compared to CONV-R dams, the GF maternal decidua exhibits similar vascular histomorphometric features at E11.5 and E17.5, and numbers …

Early Developmental Crime Prevention And Social Impact Over The Life Course, Brandon C. Welsh, Heather L. Paterson, Michael Rocque, David P. Farrington

All Faculty Scholarship

Preventing the development of criminal potential in young people is an important component of broader crime reduction strategies. A key feature of developmental crime prevention is a comprehensive effort to improve the life chances of at-risk children and families, and there is evidence that doing so improves long-term life-course outcomes like physical health, mental health, education, and employment. We assess available research evidence from 12 high-quality studies of developmental crime prevention initiatives and find that extensive use of multimodal interventions helps to foster cumulative protection over the life course, that there are significant improvements in other outcomes over the life …

Some Nonparametric Tests For High-Dimensional And Functional Data, Bilol Banerjee

Doctoral Theses

The advancement of information technology and sciences over the last few decades has facilitated the collection, storage and analysis of huge data sets. Many of these data sets contain observations having large number of features, and in some cases, this number is comparable to or even much larger than the sample size. Many traditional statistical methods cannot be meaningfully used in such situations. We develop some inferential tools for such high dimensional data. In particular, we consider the two-sample problem and the problem of testing spherical symmetry of a multivariate distributions. We construct some nonparametric tests in these contexts and …

Linguistic Identity: An Ostensive Definition, Kiesha Martin

Dissertations (1934 -)

This dissertation offers an ostensive definition of linguistic identity illustrated through historical and literary examples, lived experience, and even public policy. Linguistic identity consists of three parts: idiolect, dialect, and linguistic agency. The idiolect is a speaker’s personal identity. The dialect is a speaker’s social identity. Linguistic agency is the synthesis of both. This is an attempt to clarify the nature of the relationship between language and the self. Linguistic identity is an aspect of identity that has received scant attention in philosophy—even amidst the focus on language and linguistic analysis in this discipline. The objective is to bring linguistic …

The Lost Child: A Critique On Transracial Adoption Rhetoric, Hallie Conyers-Tucker

Seattle University Law Review

Transracial adoption in the United States reflects a deeply rooted history of colonialism, cultural assimilation, and racial hierarchy, masked by rhetoric focused on the “best interest of the child.” The author critiques that rhetoric and traces how adoption practices and policies, both domestic and international, have evolved to reinforce systemic inequities. Through historical analysis of the forced adoption of Native American, Black, and Asian children, it reveals how the best interest standard has been wielded not to protect children but to uphold political and racial ideologies. The author argues that the prevailing adoption framework relies on child-saving and color-blind narratives …

Photocatalytic Self-Pumping Membranes, Lily D. Farmer, David Warsinger, Sudharshan Anandan

Discovery Undergraduate Interdisciplinary Research Internship

The physics of nanofiltration is not well understood, as many types of membranes and filters exist, but they all interact very differently with the substance they are filtering. This research investigates membranes that can autonomously pump fluid through catalytic reactions. The first set of experiments was to collect zeta potential measurements as zeta potential is a critical property that directly affects fluid transport. Zeta potential was measured using the Anton Parr SURPASS 3, which measures the sample by streaming a given solution through a channel of membranes and uses the Smoluchowski equation to return the zeta potential value. Measurements were …

The Nature Of Anthropogenically Driven River Drying: Spatiotemporal Causes And Consequences, Eliza Inez Gilbert

Biology ETDs

Streambed drying naturally occurs in over 60% of rivers and streams worldwide. Climate change and human regulation of surface and groundwater have increased drying in naturally intermittent systems and caused perennial systems to transition to intermittency, impacting water security, water quality, and biodiversity. To understand human-induced drying dynamics, we used 12 years of daily drying data along a 154-km regulated reach of the Rio Grande. We conceptualized river drying as a regime analogous to the natural flow regime paradigm and quantified drying magnitude, rate of change, and duration. Although linear models predicting drying magnitude and rate of change were uninterpretable, …

Nitrogen Addition Additively Boosts Climate-Driven Salsola Tragus (Russian Thistle) Invasion Into Southwestern Usa Grasslands, Melissa A. Bacigalupa

Biology ETDs

Effective management of invasive, non-native plants requires understanding key drivers of invasion, including nitrogen enrichment from atmospheric deposition and agriculture. Long-term studies are essential for capturing complex invasion dynamics yet remain uncommon. We used 22 years of observations and 14 years of nitrogen experiments to examine invasion by Salsola tragus (Russian thistle) into three semi-arid grasslands of central New Mexico. Invasion patterns varied, with rapid expansion in Chihuahuan Desert grassland and the Desert-Plains ecotone but stability in Plains grassland. Under ambient nitrogen, precipitation most strongly correlated with Russian thistle biomass and high native grass biomass was associated with Russian thistle …

Navahine V. HawaiʻI Dept. Of Transportation: The Keiki Will Lead Us, Catherine Smith

Seattle University Law Review

The author analyzes the landmark case Navahine v. Hawaiʻi Department of Transportation, which culminated in the world’s first constitutional climate settlement. Catherine Smith, serving as an expert for the youth plaintiffs, situates the case within Hawaiʻi’s legal tradition of prioritizing children’s rights and intergenerational equity. She explores the evolution of children’s constitutional protections, contrasting Hawaiʻi’s progressive jurisprudence with the dominant adult-centric legal framework on the mainland. She critiques four recurring analytical missteps in U.S. courts that marginalize children’s interests and highlights Hawaiʻi’s public trust doctrine and cultural values, such as the Aloha Spirit, as models for addressing climate-related harms. …

Background:
During the postpartum period there are multiple resources available to address maternal postpartum depression. However, there are limited resources available to help fathers during this transition period. Currently, limited data is available for best practice to decrease postnatal paternal depression, and increase paternal bonding and comfortability when caring for the infant.

Method:
Fathers were recruited from a Midwestern Public Health Department. After recruitment, fathers were provided with in-home education on how to perform a light touch intervention. Pre-intervention qualitative and quantitative surveys were provided at this time. Fathers were then asked to record their emotions as well as infant …

Optimization And Model Averaging Of Histogram-Based Place Cell Firing Rate Maps Using The Point Process Framework, Murat Okatan

Turkish Journal of Electrical Engineering and Computer Sciences

The firing rate of hippocampal place cells depends on the spatial position of the organism in an environment. This position dependence is often quantified by constructing spike-in-location and time-in-location histograms, the ratio of which yields a firing rate map. The purpose of this study is to present a new method for optimizing the spatial resolution of histogram-based firing rate maps. It is pointed out that histogram-based firing rate maps are conditional intensity functions of inhomogeneous Poisson process models of neural spike trains, and, as such, they can be optimized through model selection within the point process framework. The point process …
