Do The Sexually Dimorphic Biofluorescent Glands Of Plethodon Cinereus Function In Mate Choice And Are They Seasonally Regulated By Photoperiod?, Sam C. Moody-Wynn

Masters Theses

The novel biofluorescent glands of the Eastern Red-backed Salamander (Plethodon cinereus), have been shown to be sexually dimorphic where males have larger and greater numbers of glands than females. Interestingly, a seasonal pattern of increased numbers of fluorescent glands, which mirrors the peak in testosterone levels, has been described. Currently, the function and regulation of the fluorescent glands is unknown. I predicted that the glands function as a form of male ornamentation used in intersexual communication, and perhaps act as an honest signal of male quality. Even though the fluorescent glands are located on the underside of the tail, there …

Sub-Critical Crack Growth And Fatigue Behaviour Of Alkali Silicate Glass, Noah Weyrauch

Masters Theses

"Delayed failure in silicate glasses can be linked to subcritical crack growth (SCCG) where surface defects grow over time until catastrophic failure. This phenomenon originates from stress-enhanced chemical interactions between the environment (e.g. water) and the strained silicate bonds at the crack tip. SCCG must be accounted for to predict the long-term survivability of silicate-glass components. This study compares two methods to measure SCCG parameters for a commercial alkali silicate sealing glass and for a series of binary xNa₂O-(1-x)SiO₂ glasses, where 0.15 ≤ x ≤ 0.35. A constant moment double cantilever beam (DCB) technique was used to …

Protein Turnover Rate And Life History As An Explanation Of The Extreme Difference In Cost Of Biosynthesis In Cockroach Nymphs And Painted Lady Butterfly Larva, Kyara Nicole Holloway

Masters Theses

The cost of biosynthesis in painted lady caterpillars is far lower than that of a red runner cockroach. A promising explanation for this phenomenon is the protein turnover rate for the animal during biosynthesis and tissue maintenance. Previous research has shown that, per gram of body weight, the painted lady butterfly can synthesize a biomass using up to 15x less energy and resources than the cockroach, even under similar conditions. The resulting ratios, especially in respect to growth rate, show a wide disparity between species in such a manner that does support a protein synthesis and degradation rates as a …

Navigating Black Identity: Black Young Adults’ Perception Of Being ‘Black Enough’ In America, Tabitha Omanano

Masters Theses

This thesis highlights young adults’ assumptions that social performance and certain cultural proficiencies validate one’s Blackness. I discuss cultural expressions and differences and social behaviors and why such markers and differences are insufficient to define and authenticate Black identity. I posit that the primary determinant of Blackness is a matter of biology and a shared historical context. I begin by reviewing historical and contemporary perspectives on the racial identity of African Americans and Black Africans across various eras in the United States. This is followed by analyzing the ways in which young people question their Black identities—ethnic, cultural, social, and …

Investigating Morphological And Molecular Identifiers For Culex Restuans And Culex Pipiens From Central Illinois, Savannah L. Ettien

Masters Theses

Some of the most prominent vectors for West Nile Virus are mosquitoes of the genus Culex. As a result, efforts have been made to monitor the spread of Culex species as climate change has allowed them to travel to places that they never inhabited before. Since Cx. restuans is a less prevalent vector, most studies for prevention focus on Cx. pipiens, which is the primary vector for the spread of West Nile Virus in the Midwestern United States, especially in the late summer and early fall seasons. As both species share many morphological characteristics and are present at …

Reprogramming Of Rat And Human Hepatoma Cells With Fibroblast-Specific Transcription Factors Msx1 And Pura, Merve Diler

Masters Theses

Despite all cells within an organism sharing the same genetic information, they develop into different tissues, each with a distinct gene expression profile required for tissue specialization. Understanding gene expression and the processes that regulate the expression, is crucial for understanding cell differentiation and tissue specialization, as these procedures are governed by unique gene expression and regulation patterns.

Whole genome microarray analyses identified several candidate genes that may be coding important transcription factors that play role in fibroblast identity such as Prrx1, Snai2, Shox2, Twist1, c-Fos, Msx1, Pdx1 (Idx1) and Pura (Pur1). The goal of this project is to determine …
