The goal of this research was to enhance and improve upon an organic chemistry experiment done by second year students. Extraction of essential oils is a technique used in Organic Chemistry labs in order to teach the process of steam distillation in the purification of organic samples. Through the use of steam distillation essential oils […]
B70: A Visual Laxative: Current Public Toilets in Rural Gambia Contribute to Disease and How to Change the Outcome
Diarrheal diseases, like cholera, are still impacting developing countries worldwide. New interventions, along with an addition of stronger epidemiologic surveillance needs to be considered in order to determine what methods are best for reducing the prevalence rates of these conditions. This article discusses the impact of diarrheal diseases, particularly cholera, and a new intervention strategy […]
A18: Dynamic Chemistry Produces Functional Materials with Diverse Applications
Dynamic chemistry is characterized by the ability of a bond or adduct to break or reform either autonomously or in response to stimuli, and “click” chemistry refers to a subset of one-pot, water and oxygen resistant, high-yield reactions.1,2 Herein, we use principles from both such chemistries to develop a synthesis and use RAFT (reversible addition-fragmentation […]
C56: Acoustic Impedance and Modeling Acoustic Impedance in a Trumpet Mouthpiece
The effect of acoustic impedance in any air-columns is accountable for the frequency of output sound. With noncylindrical air-columns, non-uniform cross-section area, the impedance varies continuously. An example of any instrument shows the complexity of varying impedance. In this research, advantage of having access to the impedance probe helped in developing experiment on determining the […]
B04: Inflammation can Alter Social Behavior: Is Nitric Oxide the Link?
Nitric oxide (NO) functions as both a gaseous neurotransmitter in the brain and a key signaling molecule in the innate immune system. NO is synthesized from arginine by the enzyme nitric oxide synthase (NOS). Our goal in this project was to utilize the house cricket Acheta domesticus to study the role of NO in both […]
A07: An Examination of the Function of NHE11 in Mice: a Pseudogene’s Unappreciated Role in Male Fertility?
Na+/H+ exchangers (NHEs) are transport proteins embedded in the plasma membrane that maintain proper pH in the cell by exporting hydrogen ions (H+) in exchange for extracellular sodium ions (Na+). Previous studies have shown that male mice deficient for the NHE10 protein are completely infertile due to immotile sperm. The most recently discovered isoform, NHE11, […]
B53: Expanded Research on Estimating the Total Economic Cost of Overweight and Obese Individuals—State-Level Analysis
This project builds upon the 2009 Society of Actuaries study on the estimated economic cost of overweight and obese individuals in the entire US and Canada. We found over a $235B increase in total US cost from 2009 to 2017 with the highest total cost coming from California, New York, Florida and the lowest coming […]
B12: Differences in Interspecies Aggression Observed in Invasive Cellar Spiders Pholcus phalangioides and Pholcus manueli
Cellar spider Pholcus phalangioides has been a successful invasive species in North America for over 100 years, residing in human dwellings and subsisting on a polyphagous insect diet. The arrival of a congener, Pholus manueli has led to competition between the two spiders for a very similar niche. While P. phalangioides is much larger in […]
C51: Calculation of Acoustic Impedance of a Clarinet
Acoustic impedance, one of the significant characteristics to describe the propagation of sound waves, can be simply defined as a ratio of acoustic pressure and resulting volume flow of air. To have a thorough understanding of acoustic impedance, in this project, we will conduct some calculations of the acoustic impedance of a clarinet and compare […]
B50: Skin in the Game: The Social and Economic Pressures of Prostitution in the Early American Republic
Why did women become prostitutes during the Early American Republic? A lot of work has been done on prostitution during the mid-nineteenth century, but not enough has looked at the sex trade during the nation’s founding and early-nineteenth century. This paper looks at the social and economic pressures faced by women that made them turn […]
