Stoichiometric Homeostasis In Two Native And Two Invasive South Dakotan Grasses, Joshua Thonas Harvey
Stoichiometric Homeostasis In Two Native And Two Invasive South Dakotan Grasses, Joshua Thonas Harvey
Electronic Theses and Dissertations
Increased nutrient availability has been widely linked to the success of invasive plants, however a general mechanism explaining these observations is lacking. Stoichiometric homeostasis (H), which is the regulation of internal nutrient concentrations, has been used to explain changes in plant community diversity under alterations in nutrient availability. One hypothesis holds that plants with high regulation (larger H) decrease in abundance in nutrient enriched conditions but are stable in nutrient deficient and drought conditions, likely due to extensive root systems. Additionally, plants with low regulation (lower H) increase in abundance under nutrient enriched conditions but are sensitive to drought …

Development Of Tissue-Derived Biomaterial ‘Cornea-Ecmix’: Its Utility In The Management Of Corneal Diseases, Somshuvra Bhattacharya
Electronic Theses and Dissertations
Transparent cornea, at the front of the eye, mediates vision by refracting incoming light. Due to its anatomical position, cornea is susceptible to a variety of physical and chemical insults. Severe damage caused to cornea due to trauma or disease conditions can impair vision. While the cornea’s inherent repair mechanism restores partial vision loss, transplantation is the only viable treatment option if its transparency is completely lost. A global shortage of transplantable donor tissues necessitates the need for the development of functional corneal prosthetics. As cornea mostly is made up of extracellular matrix (ECM), several studies have explored the utility …

Intra-Day Solar Irradiance Forecasting For Remote Microgrids Using Hidden Markov Model, Abhilasha Bajracharya
Intra-Day Solar Irradiance Forecasting For Remote Microgrids Using Hidden Markov Model, Abhilasha Bajracharya
Electronic Theses and Dissertations
Accurate solar irradiance forecasting is the key to accurate estimation of solar power output at any given time. The accuracy of this information is especially crucial in diesel-PV based remote microgrids with batteries to determine the set points of the batteries and generators for their optimal dispatch. This, in turn, is related directly to the overall operating cost because both an overestimation and an underestimation of the irradiance means additional operating costs for either suddenly ramping up the backup resources or causing under-utilization of the available PV power output. Accurately predicting the solar irradiance is not an easy task because …

Efficiency Of Standardized Ileal Digestible Lysine Utilization For Whole Body Protein Deposition In Pregnant Gilts And Sows During Early, Mid And Late Gestation, Christian Daniel Ramirez-Camba
Electronic Theses and Dissertations
The total daily amino acid (AA) requirements for pregnant sows are based of Lys which is the first-limiting AA in swine diets. The SID Lys requirements are estimated by the NRC (2012) gestating sow model as the sum of those required for maintenance and protein retention divided by the efficiency of SID Lys utilization. The NRC (2012) gestating sow model assumed AA efficiency is constant across stages of gestation and parities; however, this does not reflect the change in metabolic demand of various age sows at different stages of gestation. Therefore, an experiment was conducted to evaluate the efficiency of …

The Effect Of Proteolytic Queues On Antibiotic Tolerance And Persistence Cells Population In Escherichia Coli, Alawiah Abualrahi
The Effect Of Proteolytic Queues On Antibiotic Tolerance And Persistence Cells Population In Escherichia Coli, Alawiah Abualrahi
Electronic Theses and Dissertations
A major contributing factor to the abundance of antibiotic-resistant microorganisms and failed antibiotic treatment is survival due to antibiotic tolerance and persistence. Antibiotic tolerance is a widespread phenomenon that enables cells to survive treatment without carrying a resistance gene. This phenomenon renders antibiotic treatments less effective and facilitates antibiotic resistance. We are particularly interested in proteases, responsible for degradation of proteins, because of their known relationship to tolerance and persistence. Here, we examine the effects of proteases and antibiotic survival using queueing theory, in which one type of customer competes for processing by servers, that has traditionally been applied to …
