Impact Of Thermodynamic Factors And Intrinsic Properties On Crystallization Behavior And Physical Properties Of Edible Fats, Nabila Anjum

All Graduate Theses and Dissertations, Fall 2023 to Present

Crystallization behavior of three edible fats: interesterified soybean oil (IESBO), interesterified palm olein (IEPO), and fully hydrogenated palm kernel oil (FHPKO) were explored to understand how this process is affected by different factors. The study focused on how the chemical composition of these fats affects their behavior like how much time they require to be crystallized at a certain temperature. By using different scientific methods, how quickly each fat began to crystallize and how much energy it took to start the process was measured. Among the methods used, Gompertz equation, a mathematical model, gave the most consistent and reliable results …

From Mechanisms To Management: Implications Of Biogeochemical Controllers And Land Management For Soil Carbon Cycling And Storage, Savannah R. Adkins

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change and its cascading effects are driven by increases in atmospheric carbon dioxide (CO₂). Many climate solutions exists to remove this excess carbon (C) from the atmosphere, and soils, in particular, represent one of the few win-win solutions. Soils play a vital role in the global C cycle because they store more C than plants and the atmosphere combined, however, they also release more CO₂ annually than fossil fuel combustion (a major contributor to accelerating climate change). Therefore, preventing CO₂ loss from soil could help slow the progression of climate change, and increasing overall soil …

With iron supplementation often resulting in gastrointestinal symptoms that could negatively impact sport performance itself there is a need to explore other …

Understanding Impact Of Starter Culture Blends On The Ph Variation In Cheddar Cheese During Early Aging, Samuel J. Clarke

All Graduate Theses and Dissertations, Fall 2023 to Present

Consumer expectations govern what is acceptable when it comes to the flavor, texture, and color of the cheese. These quality attributes of cheese are all influenced by the pH of the cheese which is in turn controlled by the acid production of the starter lactic acid bacteria (SLAB) used to make cheese. Whatever the final pH of the cheese is, is what determines the quality of the cheese. Unfortunately, there are some Cheddar cheese manufacturers that have observed pH variation during the early aging of their cheeses. We hypothesize that the addition of thermophilic, fast-acid producing bacteria, like Streptococcus thermophilus …

Error Reduction Methodology And Data Simulation For Interval Data, Ranik Christopher Jelinek

Undergraduate Honors Capstone Projects

Chronic kidney disease (CKD) is a progressive condition affecting hundreds of millions of individuals worldwide. However, clinical datasets often record continuous laboratory measurements as categorical intervals rather than precise numerical values. This interval-censored structure presents methodological challenges for standard regression-based classifiers. This study compares three strategies for handling interval-valued predictors prior to fitting a logistic LASSO model: (1) midpoint imputation, which replaces each interval with its arithmetic center; (2) ordinal encoding, which maps intervals to integer ranks; and (3) a Monte Carlo simulation approach, which repeatedly samples uniformly from each observed interval and averages predictions across replications. Using a 10-fold …

Tannin Supplementation Alters Foraging Behavior And Spatial Distribution In Beef Cattle, Bashiri Iddy Muzzo, R. Douglas Ramsey, Kelvyn Bladen, Juan J. Villalba

Wildland Resources Student Research

Beef production on chemically uniform grass monocultures can limit nutrient synchrony and contribute to uneven pasture use. We evaluated whether supplementing tannins with bioactive plant secondary compounds improves foraging dynamics and landscape use by beef cattle grazing a meadow bromegrass monoculture in ways aligned with rangeland sustainability. Twenty-four Angus cow–calf pairs were allocated to six 3.6-ha paddocks (four pairs/paddock), randomly assigned to Control (Ctrl; n = 3) or Tannin treatment (TT; n = 3). Animals received 1 kg/cow/day of DDGs, with TT receiving an added 0.4% tannins (2:1 condensed:hydrolyzable). Grazing occurred during four 15-day periods (July– September) across two years. …
