Characterizing The Expression Pattern And Function Of Tartan During Drosophila Development, Alaina Baggett

Biomedical Engineering Undergraduate Honors Theses

The development of complex structures and organs by multicellular organisms relies on the ability of epithelial cells to self-organize. Epithelia are sheets of connected cells, and compartment boundaries are formed between certain epithelial cells to create distinct tissue compartments. Compartment boundaries are specialized cell-cell interfaces that are enriched for the cytoskeletal proteins actin and myosin, leading to straight cell edges under relatively high tension that act as fences keep cells from moving between compartments. In the model organism Drosophila melanogaster (fruit fly), compartment boundaries in the early embryo are established in response to the non-uniform striped expression of the cell-surface …

Flow Characteristics Through Granular Soil Influenced By Saline Water Intrusion: A Laboratory Investigation, Sudip Basack, Ghritartha Goswami, Hadi Khabbaz, M Karakouzian

Civil and Environmental Engineering and Construction Faculty Research

The coastal geoenvironment initiates saline water intrusion into the freshwater aquifers, producing a geohydraulic problem. Such intrusion not only contaminates the fresh groundwater resources, making them unsuitable for human use, but also alters the hydraulic conductivity of the aquifer materials, which affects the coastal groundwater flow, influencing the water resources planning and management. Past investigations reveal that the groundwater flow can be linear or nonlinear depending upon the hydraulic gradient. Thus, the coefficients of nonlinear hydraulic conductivities are affected by saltwater intrusion. The present study focuses on an in-depth laboratory investigation into the influence of saltwater submergence on the nonlinear …

The Design, Prototype, And Testing Of A Robotic Prosthetic Leg, Michael Davidson

Loma Linda University Electronic Theses, Dissertations & Projects

Since antiquity, health professionals have sought ways to provide and improve prosthetic devices to ease the suffering of those living with limb loss. Mid-century modern engineering techniques, in part, developed and funded by the American industrial war effort, led to numerous innovations and standardization of mass-customized products. Followed by the Digital Revolution, we are now experiencing the roboticization of prosthetic limbs. As innovations have come and gone, some essential technologies have been forgotten or ignored.

Large Eddy Simulation Of The Wakes Of Three Urban Air Mobility Vehicles, Denis-Gabriel Caprace, Andrew Ning

Faculty Publications

Recent advances in urban air mobility have driven the development of many new VTOL concepts. These vehicles often feature original designs and futuristic shapes. Due to their novelty, the wake characteristics of such aircraft are unknown. However, large wake-induced velocities, should they exist, may be dangerous for any other vehicle evolving in their close proximity. Therefore, improved knowledge about the wakes of VTOL vehicles is needed to guarantee the safety of urban air mobility operations. In this work, we study the wake of three VTOL aircraft in cruise by means of large eddy simulation. We present a two-stage numerical procedure …

From Zero To Thrive: A Model Of Cross-System And Cross-Sector Relational Health To Promote Early Childhood Development Across The Child-Serving Ecosystem, Alison L. Miller, Sara F. Stein, Rebeccah Sokol, Rachel Varisco, Phoebe Trout, Megan M. Julian, Julie Ribaudo, Joshua B. Kay, Natasha V. Pilkauskas, Nicole Gardner-Neblett, Todd I. Herrenkohl, Kara Zivin, Maria Muzik, Katherine L. Rosenblum

Articles

Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a “child-serving ecosystem”, that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the …

Changes In Western U.S. Streamflow Extremes Under Climate Change, Rama Bedri

Student Scholar Symposium Abstracts and Posters

We are analyzing streamflow extremes in Western U.S. rivers due to climate change. Global warming causes natural disasters to reach extreme points and affects river volumes, snowfall, and precipitation amounts. We analyze the data for 17 stations in the Colorado River Basin, whose rivers provide Southern California’s drinking water supply. Disruptions in streamflow due to climate change affect the region’s water availability and make it difficult to predict future trends. We compared historical streamflow data to eight possible climate scenarios. The different scenarios are Warm Dry, Cool Wet, Average, and Other at emission levels of RCP 4.5 and 8.5. First, …

Computational Design Of Β-Fluorinated Morphine Derivatives For Ph-Specific Binding, Nayiri Alexander, Makena Augenstein, Matthew Gartner

Student Scholar Symposium Abstracts and Posters

The opioid epidemic impacted over 12 million Americans in 2019. Although they are effective pain-relieving medications, they carry addictive and dangerous side effects. Opioids, like morphine, bind non-selectively in both central and peripheral tissues; however, dangerous side effects result from central activation. Inflamed conditions of injured tissues have a lower pH (pH=6-6.5) environment than healthy central tissue (pH=7.4). We aim to design a morphine derivative that binds selectively within inflamed tissue using computationally-based molecular extension and dissection techniques. Binding to the mu-opioid receptor (MOR) is dependent on protonation of the biochemically active amine group of morphine. Fluorination of a carbon …

Ketone Hydrosilylation Studies Using A Carbodiphosphorane Catalyst, Liam Sullivan, Allegra Liberman-Martin

Student Scholar Symposium Abstracts and Posters

The objective of this research is to discover an effective, safe, and low-cost catalyst for ketone hydrosilylation reactions, which involve the addition of a silicon–hydrogen bond across a C=O double bond. Improving catalyst efficiency could benefit the organic synthesis industry, as carbonyl hydrosilylation is used industrially in the synthesis of alcohol products. Use of the carbodiphosphorane catalyst as a replacement for toxic heavy-metal-containing catalysts could reduce waste and emissions harmful to the environment, while also providing an alternative means for accomplishing ketone reduction. Using a cyclic carbodiphosphorane catalyst, we have compared catalytic activity toward acetophenone hydrosilylation for a range of …

Lost Memories, Lost Colonies, Emma C. Smith

Honors Theses

The Roanoke Colony was the first English colony in America. The colonists were abandonded by the Governor shortly after the colony was established. In public memory, the fate of the colony is highly debated and has since become an American founding myth. As a result of the contested fate, the story of Roanoke has since become a blank slate upon which other legends can evolve. These legends become a window for historians into the insecurities of those who created them. This paper discusses why the English wanted to establish a colony, the popularization of Pocahontas, the history of marriages between …

A Cold War On The Dark Knight: Batman And American Culture 1939-1975, Angelica Cantrell

The Interplay Between Personal Responsibility And Social Determinants Of Health On Attributions Related To Covid-19 Infections, Emma Cox

Honors Theses

While health campaigns often convey that health-related behaviors are the primary causes of preventable illnesses, they ignore the strong relationship between social determinants of health (SDH) and health outcomes (Braveman & Gottlieb, 2014). Ignoring non-behavioral factors in health communication poses both practical and ethical concerns for people with negative health outcomes, as health is linked to many “uncontrollable” factors, including income, education, and employment (Guttman & Ressler, 2001). Several social and environmental factors are linked to covid-19 exposure risk, including neighborhood environment, housing conditions, and occupation (CDC, 2022). Given the associations between causal beliefs about health and policy support, experts …
