Humeral Head Retroversion On A Contemporary Skeletal Population With Known Physical Activity To Investigate The Differential Expressions Of Biological Sex, Elizabeth Hightower

Electronic Theses and Dissertations 2020 - Present

Retroversion is an angled measurement of the humerus that is indicative of habitual overhand activity. Elevated retroversion measurements (in degrees) indicate overhand activity. Overhand activity indicates subsistence gathering from spear or atlatl throwing. Most retroversion research is conducted in populations where men perform more physically demanding labor. Therefore, bioarchaeologists are producing the same data over and over. Additionally, contemporary retroversion data is used as comparative figures. These subjects range from youth to professional baseball players, but the data on women is nearly obsolete. Bioarchaeology needs contemporary female retroversion data. Research was conducted at the University of Tennessee Knoxville where humeral …

School of Biological and Marine Sciences

Coastal managers worldwide must prepare for changes in annual wave overtopping events due to climate change and sea-level rise. Research often assesses overtopping discharges by extreme events at a sea wall crest, typically using data from physical models or empirical rules based on scaled experiments. Here, we analyse a unique 1-year field dataset of coastal wave overtopping, from SW England, to determine the number of individual waves, regardless of their size, overtopping two locations across a coastal structure. The coastal conditions causing the most frequent overtopping differ from those driving it landward, complicating hazard communications for multiuse infrastructure. These data …

Depth-Variant Deconvolution Applied To Widefield Microscopy For Rapid Large-Volume Tissue Imaging, Daniel D Lee, Kevin A Telfer, Mark A J Koenis, Yim K Lee, Kevin W Namink, Brian T Saunders, Heyun Lee, Hailey Kelley, Heather S Ruiz, Joseph P Gaut, Gwendalyn J Randolph, Bernd H Zinselmeyer

2020-Current year OA Pubs

Innovations in 3D tissue imaging have revolutionized research, but limitations stemming from lengthy protocols and equipment accessibility persist. Widefield microscopy is fast and accessible but often excluded from 3D imaging workflows due to its lack of optical sectioning. Here we combine tissue clearing with a commercial depth-variant deconvolution approach that we optimized for large-volume widefield imaging. By implementing prefiltering with z-brick splitting, we achieve subnuclear axial resolution in tissues to a depth of 500 µm in multi-tile scan images. We illustrate the utility of this method in a model of ileitis and to gain a 3D perspective in thick brain …

Between Shadows and Light

The fog moved like a living thing as Evan Cole stepped out of the train station. Windmere smelled the same as it had twenty years ago—salt, rust, and old fish. The town felt shrunken, worn down, like time had been grinding it slowly into dust.

He hadn’t wanted to return. If not for his grandmother’s death, he never would have. But her house on Seabright Lane now belonged to him, and he needed to settle her affairs.

Inside the house, everything was covered in dust: her armchair, the ceramic gulls on the mantel, the photo of …

Belonging Without Borders: A Missionary Kid Reflects On Nursing School, Julia Beth Stamp

Wisdom & Compassion: The LUSON Journal

This reflective essay examines the experience of pursuing a nursing degree while living far from home as a Missionary Kid. It explores how the absence of close family ties during nursing school intensified feelings of loneliness, challenged motivation, and strained emotional well-being. Interwoven with personal narrative and supported by recent literature, the reflection highlights the way that community— through peers, mentors, and faculty— emerged as a vital source of resilience. The essay argues that resilience in nursing education is not the product of individual grit alone but grows from interdependence and the willingness to seek and receive support. Through recounting …
