Door Accessibility: Contemplating The Americans With Disabilities Act At Clemson University, Brian Duffy

Graduate Research and Discovery Symposium (GRADS)

Several door thresholds do not meet The Americans with Disabilities Act (ADA) guidelines whereby compromising the ability for a person in a wheelchair to easily pass through a door opening. Utilizing a qualitative research approach, data were collected using simulation methods and face-to-face interviews. Twelve doors were studied to determine if the threshold heights comply with ADA code A4.13.8. Results show that many doors are not meeting ADA code. Recommendations are provided to show how improving door closers, door width, and sill plate design will improve accessibility for those in wheelchairs.

The urinary bladder is one of the few organs that has been successfully engineered and implanted in humans for a long-term clinical trial .However; scaffolds such as PGA-collagen used in the previous studies possess inadequate mechanical properties for organs that exhibit large deformation. The present study explored the use of biodegradable elastomers, poly-glycerol sebacate-polycaprolactone (PGS-PCl), poly (ether-urethane) urea (PEUU), and poly (carbonate-urethane) urea (PCUU) for urinary bladder tissue engineering since these materials have previously been shown to exhibit high extensibility and cytocompatibility. The present study compared mechanical properties of PGS-PCL, PEUU& PCUU elastomers. PGS-PCL, PEUU and wet PCUU specimens were …


Sinusoidal Spacers For Mitigating Concentration Polarization In Reverse Osmosis , Peng Xie, David A. Ladner Apr 2013

Sinusoidal Spacers For Mitigating Concentration Polarization In Reverse Osmosis , Peng Xie, David A. Ladner

Graduate Research and Discovery Symposium (GRADS)

To improve the current mesh feed spacer we developed spacers with a geometry that causes sinusoidal flow patterns. These have two main advantages: unobstructed flow and adaptable geometry. First, this design allows unobstructed flow inside the membrane channel so as to minimize longitudinal pressure drop and dead zones. Second, the frequency and amplitude of the sinusoidal (along with the width and height of the flow channels) can be tuned, thus changing the crossflow velocity independent of the total module flow rate. Faster crossflow velocity is achieved with higher amplitude and frequency of the sinusoids. Analysis of the designs was accomplished …

Predicting Team V. Individual Surgical Flow Disruption Recovery In Cardiothoracic Operating Rooms , Gary Palmer Ii, A. Joy Rivera-Rodriguez

Graduate Research and Discovery Symposium (GRADS)

Patient safety is a major concern of healthcare organizations and healthcare providers. It is generally, a vital component that most hospitals instill within their culture to prevent sentinel events from occurring. One area of concern that has been a growing topic in literature recently, is the study of surgical flow disruptions (SFDs). SFDs are events that disrupt the flow of the surgical procedure. SFDs are being used as a new metric of patient safety in the operating room (OR), and as the more SFDs occur, the more opportunity there is for errors. Therefore, one way to increase patient safety in …


Access To Higher Education And The College Choice Of Rural Low-Income Students , Chinasa A. Ordu Apr 2013

Access To Higher Education And The College Choice Of Rural Low-Income Students , Chinasa A. Ordu

Graduate Research and Discovery Symposium (GRADS)

The viability of obtaining a college education is being challenged. As higher education has been touted as the means for increasing one’s economic mobility, financing a college education can be a deterrent for those from low-income backgrounds. Past research has highlighted that financial aid offered in the form of grants as having a great impact on the college enrollment patterns of students from underserved, low-income backgrounds (Leslie & Brinkman,1988); however with the financial aid shift from grants to loans, student loans are being used primarily by this group to fund their education. Unfortunately, student loan debt has soared over $1 …

Fate And Behavior Of Titanium Dioxide In Aquatic Ecosystems , Jason Coral Apr 2013

Fate And Behavior Of Titanium Dioxide In Aquatic Ecosystems , Jason Coral

Graduate Research and Discovery Symposium (GRADS)

One common use of TiO2 particles is use in sunscreen. As a result of aggressive sunscreen campaigns sponsored by the CDC in the early 2000’s, sunscreen use is high. As a result, there is concern that the nanoparticles that make these sunscreens effective wash off of sunbathers in the water. The fate and impact of these nanoparticles in aquatic ecosystems is uncertain. Recent research has shown that these nanoparticles form reactive oxygen species (ROS) that may be harmful to aquatic organisms. The objective of this research is to characterize the production of reactive oxygen species created by TiO2 nanoparticles being …

How Clean Is A Restaurant Menu? A Study Of Bacterial Transfer To And From Restaurant Menus , Ibtehal Alsallaiy, Paul Dawson, Inyee Han

Graduate Research and Discovery Symposium (GRADS)

Some non-food contact surfaces such as restaurant menus are not routinely evaluated for microbial contamination thus can be a potential contamination risk. The main objectives of this study were to detect bacteria on restaurant menus, test the rate of bacteria transfer from menus to consumers and determine the survival rate of bacteria on the menu surface. Samples collected from local restaurants’ menus and analyzed for total aerobic organisms and Staphylococcus spp, indicated that menus often harbored detectable levels of bacteria. The average transfer rate was 11.17%, with a high variability between subjects (10.45% standard deviation). Survival rate of bacteria was …


Securitization, Credit Derivatives And Bank Failure , Danielle Zanzalari Apr 2013

Securitization, Credit Derivatives And Bank Failure , Danielle Zanzalari

Graduate Research and Discovery Symposium (GRADS)

During America’s most recent recession, more than 281 banks failed between 2006-2010, roughly 1,200% more failures than the previous five years. In April 2011, asset-backed securities grew to a high of $11 trillion more than the outstanding value of all U.S. Treasuries combined. My research explores to what extent insurance on asset-backed securities, called credit derivative swaps, led to bank failure. I also explore the determinants leading to bank securitization. Early research indicates that the stock market was able to avoid the pitfalls of asymmetric information when analyzing off-balance sheet items.

Biological And Chemical Mechanisms For 2,4-Dinitroanisole (Dnan) Degradation , Jolanta B. Niedzwiecka, Kevin T. Finneran, Clint Arnett

Graduate Research and Discovery Symposium (GRADS)

The insensitive munition,2,4-dinitroanisole(DNAN), has been used in newly developed explosives as a replacement for the more sensitive munition, trinitrotoluene(TNT). It is important to understand the fate of DNAN in the environment and to establish effective remediation methods due to its high toxicity and potential environmental hazards, should it migrate from Department of Defense facilities in groundwater contamination. We investigated DNAN reduction by aqueous phase Fe(II), organically-complexed iron(II) with several possible Fe(II) ligands, and using model Fe(III)-reducing microorganisms such as Geobacter metallireducens. Data demonstrated that DNAN was completely reduced by Fe(II) alone as well as Fe(II)-ligand complexes including tiron, 2,3-DMSA, 3,4-DHBA, …
