Eta Carinae Left A Curious Ladder To Climb, Theodore R. Gull, Henrik Hartman, Michael F. Corcoran, Augusto Damineli, Thomas Madura, Anthony F J Moffat, Noel D. Richardson, Gerd Weigelt

Faculty Research, Scholarly, and Creative Activity

Eta Carinae underwent the Great Eruption in the 1840s and a Lesser Eruption in the 1890s. Its apparent spectrum, modified by intervening ejecta, the Homunculus and Little Homunculus, continues to evolve but contains information pertaining to events in the 19th century. The LOS spectrum contains narrow absorption velocities, from -122 to -1665 km/s: rungs of a broken ladder caused by shells formed by the interacting winds. Estimated shell origin dates correlate with origin dates of expanding emission structures preceding the Great Eruption. The LOS absorption velocities extend the record post Great Eruption to the Lesser Eruption. We suggest that these …

A Tough Bioadhesive Hydrogel Supports Sutureless Sealing Of The Dural Membrane In Porcine And Ex Vivo Human Tissue, Kyle C Wu, Benjamin R Freedman, Phoebe S Kwon, Matthew Torre, Daniel O Kent, Wenya Linda Bi, David J Mooney

Duncan NRI Faculty and Staff Publications

Complete sequestration of central nervous system tissue and cerebrospinal fluid by the dural membrane is fundamental to maintaining homeostasis and proper organ function, making reconstruction of this layer an essential step during neurosurgery. Primary closure of the dura by suture repair is the current standard, despite facing technical, microenvironmental, and anatomic challenges. Here, we apply a mechanically tough hydrogel paired with a bioadhesive for intraoperative sealing of the dural membrane in rodent, porcine, and human central nervous system tissue. Tensile testing demonstrated that this dural tough adhesive (DTA) exhibited greater toughness with higher maximum stress and stretch compared with commercial …

N-H Nhc Palladium Catalysts Derived From Unique 2-Phosphinoimidazole Precursors For C-C Cross Coupling Reactions And Application Of Slow Releasing Polymers Impregnated With Gibberellic Acid To Overcome Seed Dormancy For Land Reclamation, Alexandra Jean Setelin Larson

Theses and Dissertations

Organometallic chemistry is highly dependent upon the ligands which are employed on a metal's surface. These ligands control steric bulk and electronics of the metal center which can change the reactivity of the organometallic complex. Ligands that are standard in organometallic chemistry include phosphine ligands. These phosphine ligands have been utilized in the field since the 1960's and have shaped the development of many key organometallic catalysts. Phosphine ligands are easily functionalized and highly reactive. This increased reactivity, however, causes severe limitations as phosphine ligands are often unstable under standard benchtop conditions and must be handled both air and moisture …

Intersectionalities Of Systematic Barriers Set Upon Underrepresented Students In Stem: Capturing The Potential Benefits Of Online Modality, Raiyasha Aiyanna Paris

University Honors Theses

The prevalence of racism and microaggressions in STEM disciplines within colleges presents significant hurdles to the academic success and well-being of underrepresented students. Microaggressions, encompassing subtle biases and stereotyping, have a cumulative impact, inducing heightened stress, diminished motivation, and reduced self-efficacy among minority students, thereby impeding cognitive functioning and hindering academic progress (Ogunyemi et al., 2020). The existence of these negative emotional responses creates a less conducive learning environment for academic achievement. Additionally, structural inequalities within STEM institutions contribute to disparities in resource access, limited mentorship opportunities, and support networks crucial for success in STEM fields (Atkins et al., 2020). …

Effects Of Stroboscopic Vision On Depth Jump Motor Control: A Biomechanical Analysis, Kenneth D. Harrison, Christopher J. Dakin, Anne Z. Beethe, Talin Louder

Kinesiology and Health Science Faculty Publications

Researchers commonly use the 'free-fall' paradigm to investigate motor control during landing impacts, particularly in drop landings and depth jumps (DJ). While recent studies have focused on the impact of vision on landing motor control, previous research fully removed continuous visual input, limiting ecological validity. The aim of this investigation was to evaluate the effects of stroboscopic vision on depth jump (DJ) motor control. Ground reaction forces (GRF) and lower-extremity surface electromyography (EMG) were collected for 20 young adults (11 male; 9 female) performing six depth jumps (0.51 m drop height) in each of two visual conditions (full vision vs. …

Physical Activity Barriers And Facilitators In African American Women: A Social Ecological Models Perspective, Leah Ann Carter

LSU Doctoral Dissertations

African American (AA) women experience poor health outcomes that can be addressed by increasing PA engagement. Understanding how PA barriers and facilitators occur at multiple levels of influence may help tailor PA interventions for AA women. Although prior work has established barriers to PA that are unique to African American women, few studies identify the sociocultural norms associated with these impediments. Little is known about the cultural implications of barriers such as haircare maintenance, and public policy.

The primary aim of this dissertation was to capture AA women’s voice about PA barriers and facilitators using the social ecological model framework. …

What Is Eai? A Short History Of The Style’S Evolution And Development Of Identifiable Characteristics, Dylan Burchett

LSU Doctoral Dissertations

EAI (Electro-Acoustic Improvisation) has long presented issues pertaining to its definition and practice. This is due to the wide range of acoustic and electronic sounds present in the style as well as the style’s stated adherence to improvisation. This stated adherence to improvisation and wide potential range of acoustic and electronic sounds seem to clash with EAI’s stylistic consistencies. Because the EAI style has been difficult to define, it has also been difficult to place historically within experimental music traditions. In order to clarify the definition, practice, and historical positioning of EAI and identify where the style’s boundary lines around …
