Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal
Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal

The United States spends $20 billion each year on farm subsidies. Farmers face increased risk and income variation when their crop portfolio is less diversified. It’s possible for farm subsidies to decrease diversification if they are focused on specific crops. Utilizing state level subsidy and agricultural data from the Environmental Working Group, I used econometric analysis to estimate the effect of farm subsidies on crop diversification. I used the number of acres planted from the 15 top most subsidized and grown crops in the United States to derive my dependent variable, the Herfindahl-Hirschman index (HHI). The HHI is a market …

Polarized protein secretion is a fundamental process for all organisms, from yeast to higher eukaryotes. The secretory pathway in eukaryotes includes many steps mediated by hundreds of essential proteins. Our interest lies on Sec6, which is an 88kDa protein subunit of the tethering complex named exocyst, which is known to play diverse roles in recognition, tethering, and SNARE-mediated fusion of secretory vesicles. Previous work on Sec6 done by Munson and Songer (2009) explored phenotypes of two novel SEC6 mutant proteins, whose conserved surface amino acids had been altered. Both sec6-49 and sec6-54 mutant alleles displayed severe temperature sensitive growth and …
Determination Of The Binding Site Of Adenovirus E4 11k On The Cellular Protein Ddx6, Clint E. Edmunds, Courtney F. Moon
Determination Of The Binding Site Of Adenovirus E4 11k On The Cellular Protein Ddx6, Clint E. Edmunds, Courtney F. Moon

Adenovirus is a double-stranded DNA virus that is responsible for localized infections, such as upper respiratory tract infections. The virus takes over the target cell through many mechanisms, in particular taking control of host cell gene expression mechanisms as well as controlling host cell protein synthesis machinery. One of the functions of the adenovirus E4 11k protein is in turning off host cell protein synthesis and regulating late viral gene expression. E4 11k from all adenovirus subclasses has been shown to disrupt cellular RNA processing bodies (P-bodies), and adenovirus serotype 5 has a direct interaction with a P-body protein, Ddx6. …
Impact Of Cations On The Sorption Capabilities Of Kaolin Towards Biofilm-Forming Bacteria, Rachel E. Brineman
Impact Of Cations On The Sorption Capabilities Of Kaolin Towards Biofilm-Forming Bacteria, Rachel E. Brineman
Georgia College Student Research Events
Biofilm-forming bacteria cause problems for industries such as medical, food, and water treatment. Due to its heterogeneous charges, kaolin is capable of sorption of these microorganisms. These charges are impacted by pH and cations, which change the electrostatic interactions between kaolin particles and microorganisms. Proper pH and cation composition may lead to enhanced sorption. The impact of Al3+ cations on kaolin sorption of Gram negative (E. coli and P. aeruginosa) and Gram positive (B. megaterium and S. aureus) was investigated. Calcined kaolin and Diatomaceous Earth kaolin, which were selected in previous studies, were incubated in triplicates with the above organisms …
