Having A Cow: Exploring The Economic And Mental Health Challenges Of Dairying In The Upper Valley, Ava J. Ori

Environmental Studies Senior Theses

Until late in the 20th century, the dairyman was an influential actor in the fabric of the Upper Valley consisting of Grafton, Orange, Sullivan and Windsor counties (Rozwenc, 1981 & Weld, 1905). Dairy farmers were critical to both the economic growth of the region and the construction of a local identity centered around distinctive high quality dairy products. However, the dairy farmers responsible for the bucolic feel and scrappy independence unique to the Upper Valley are being traded in for massive operations lacking both quality of milk and the cultural intricacy specific to local dairies. In 1905 there were 4,173 …

Microwave-Assisted Synthesis And Surface Characterization Of Graphene Oxide-Antimony Trioxide Nanocomposites For Ascorbic Acid Electrochemical Sensor, Samir Mallick

Nanoparticles have played a critical role in developing affordable, sensitive, and selective sensors. This work reports on the electrochemical detection of AA using glassy carbon electrodes (GCEs) modified with microwave-assisted graphene oxide-antimony trioxide nanocomposite and chitosan films. The developed sensor displayed enhanced electron transfer and a better electrocatalytic reaction towards AA compared to other fabricated electrodes. Cyclic voltammetry and chronoamperometry were used for electrochemical measurements. CV and Fourier …

Isolating Novel Enzymes And Microorganisms For Use In Food Waste Fermentation, Shannon Marie Jeffries

Tennessee State University Alumni Theses and Dissertations

In the United States, upwards of 2 billion pounds of food waste are discarded yearly, an amount equivalent to $161 billion or 30-40% of all food production, making up the largest portion of landfill waste (Buzby, 2022). A small amount of food scraps are recycled through compost and re-purposed into animal feed, but these processes are costly, have minimal benefits, and have limitations (EPA, 2024). One of the most promising routes is converting food waste into value added products through microbial fermentation. Food waste is rich in carbohydrates, proteins, lipids, vitamins, and other trace minerals, making it the ideal environment …

Evaluating Safety Assurance Of Ai Classifiers Trained On Systematically Generated Sar Imagery, Branndon Jones

Tennessee State University Alumni Theses and Dissertations

The collection and curation of high-quality data is crucial for developing robust and trustworthy deep learning (DL) models. Due to the costly and time-consuming nature of gathering well-annotated data, researchers have shifted to supplementing network training with synthetic data. However, when solely training AI classifiers with synthetic data, the network performance when exposed to data from real environments may not be satisfactory. To mitigate this shortcoming, a Gen-AI model was developed to systematically generate annotated, context-controlled synthetic imagery datasets using real SAR imagery. Through this process, SAR images of targets of interests are initially semantically segmented and introduced onto the …

Molecular Insights Into The Role Of Estrogen Receptor Beta In Ecdysterone Mediated Anabolic Activity, Syeda Sumayya Tariq, Madiha Sardar, Muhammad Shafiq, Hendrick Heinz, Mohammad Nur-E-Alam, Aftab Ahmad, Zaheer Ul-Haq

Pharmacy Faculty Articles and Research

Ecdysterone, often dubbed a “natural steroid,” has garnered significant attention among athletes for its reputed growth-promoting and anabolic properties. Unlike synthetic anabolic steroids, which are classified as controlled substances, ecdysteroids remain largely unregulated in many countries and are widely marketed as dietary supplements. Notably, ecdysterone has been included in the World Anti-Doping Agency (WADA) monitoring program, highlighting its potential impact on athletic performance and raising questions about its regulation. Emerging evidence indicates that, unlike traditional anabolic steroids that act primarily via the Androgen Receptor (AR), ecdysterone’s anabolic effects may be mediated through Estrogen Receptors (ERs), particularly Estrogen Receptor beta (ERβ). …
