Near Real-Time Determination Of The Prevalence Of Cannabinoids, Cathinones, And Synthetic Opioids, Catherine O'Rourke, Bikram Subedi

Scholars Week

Unregulated new psychoactive substances (NPS) in “pure” or “preparation” forms are designed to mimic the effects of controlled substances, and are introduced and reintroduced in the market as a cheap substitute of established regulated drugs in quick succession to loophole the law enforcement efforts on combating drugs. For example, carfentanil, a synthetic opioid activates the opioid receptors similar to morphine but it is astoundingly potent compared to a typical drug of abuse (100 times more potent than fentanyl and 10,000 times more powerful than morphine). Based on the cost- and time-intensive forensic analysis, National Drug Early Warning System reported the …

Studying The Glacial Melt Of Mount Baker Using Remote Sensing (1999 - 2019), Cole Fletcher

Scholars Week

With rising temperatures glaciers around the globe are beginning to melt. Melting of large glaciers should be concerning as they can raise the present sea-level which could potentially put near sea-level urban areas underwater. We must observe the rate at which glaciers are retreating. Mountain glaciers are a good resource to observe as they do give a clear visual of how fast glaciers are retreating. This project hopes to give a good visual representation and quantitative measurement of how much glacial melt is occurring at Mt Baker in Washington, United States, in the last 20 years. This project will use …


An Industrial Hygiene Assessment Of Lead In Potable Water Outlets At Rowan University, Tyra Thomas, Rosemary Roberto, Thomas Boyle May 2019

An Industrial Hygiene Assessment Of Lead In Potable Water Outlets At Rowan University, Tyra Thomas, Rosemary Roberto, Thomas Boyle

Rowan-Virtua Research Day

The Office of Environmental Health and Safety (EHS) discovered lead in the water of a number of buildings on the Glassboro campus. This finding triggered the need for a comprehensive study to determine if lead was in the drinking water on the main campus.

Rowan University then partnered with an independent consultant to create a Lead Sampling Plan, collect water samples and to find a certified laboratory to provide water sample analysis.

A comprehensive plumbing survey of the campus also took place to determine how water is supplied to campus and how it is distributed to and throughout each building. …


Does Clean Energy Make Or Break A Country?, Madhav Parthasarathy, Aidan T. Stueck, Xander Van Horn May 2019

Does Clean Energy Make Or Break A Country?, Madhav Parthasarathy, Aidan T. Stueck, Xander Van Horn

Student Leadership Exchange (SLX)

With the world running low on fossil fuels and energy sources, it is as vital as ever to educate ourselves on the newest forms of alternative energy sources. Countries as of now are extremely reliant on energy and this reliance affects all aspects of life including school life, home life, and social life as well. By statistically comparing traits of successful countries to the cleanness of their energy, we can discover the benefits of implementing a clean, efficient energy system to replace the fossil fuels in our country. Whether it be a higher GDP, a thriving economy, or quality education, …


Strategic Analysis Of New Jersey's Lsrp Program By Applying A Combined Swot-Ahp Technique, Robert Oleksy Apr 2019

Strategic Analysis Of New Jersey's Lsrp Program By Applying A Combined Swot-Ahp Technique, Robert Oleksy

Sigma Xi Student Research Symposium

In 2009 the Site Remediation Reform Act (SRRA) was established which created the Licensed Site Remediation Professions (LSRP) program. LSRPs can provide remediation services without delayed approval from the New Jersey Department of Environmental Protection (NJDEP). The result allows for prompt development of contaminated sites. Ten years after its passage, SRRA 2.0 will soon be introduced. To assist in its strategic development, a modified Strength, Weakness, Opportunities and Threats - Analytical Hierarch Process (SWOT-AHP) will be applied to four stockholder groups to determine each groups' preferences of the current LSRP program. The four groups include government/legal entities, business/trade organizations, non-government …


Risk Assessment For Tce Contamination At The Plymouth Tube Sitegila River Indian Reservation, Az, Eric Canteenwala Apr 2019

Risk Assessment For Tce Contamination At The Plymouth Tube Sitegila River Indian Reservation, Az, Eric Canteenwala

Creative Activity and Research Day - CARD

Trichloroethylene or TCE is a volatile organic compound and Group A known human carcinogen that has been widely used in a variety of industrial and commercial applications and is one of the most common types of environmental contaminants found at industrial sites. A human health risk assessment was conducted using indoor air, soil vapor and groundwater monitoring well sample data to assess whether historic contamination posed a current risk to workers occupying a factory at the former Plymouth Tube Site in Chandler, Arizona. Sample data was analyzed using US EPA guidance and basic risk assessment calculations to quantify the cancerous …

Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter Apr 2019

Using X-Ray Fluorescence To Analyze Fire Impacted Soil And Vegetation Composition, Dylan Darter

Kansas State University Undergraduate Research Conference

In our lab, I am using an X-ray fluorescence (XRF) to measure the concentrations of metals in sediments from subalpine lakes. Our goal is to measure the biogeochemical consequences of wildfires over the last 2000 years. This study looks at the elemental composition of different lake cores, and vegetation samples from areas of the “Big Burn” fire of 1910. This fire burned across several states in the Rocky Mountain region. With our XRF data we are able to see how the fire impacted the soils and how long after the fire proper soil composition can occur. This study can be …


Hour-Level Resolution On Consumption Pattern Of Substance Abuse, Jarrett Mauk, Rhiannon Huffines, Brittney Nelson, Tara Croft, Bikram Subedi Apr 2019

Hour-Level Resolution On Consumption Pattern Of Substance Abuse, Jarrett Mauk, Rhiannon Huffines, Brittney Nelson, Tara Croft, Bikram Subedi

Scholars Week

Conventional survey-based approaches of determining the consumption statistics of drugs in communities are suffered from non-response biases, and typically underestimate the actual consumption. Time and cost-intensive conventional approaches, therefore, can’t be utilized to determine high-resolution temporal variability in drug consumption. In this study, the temporal trend of consumption of 10 illicit and 26 prescribed neuropsychiatric drugs was determined at hour-level resolution utilizing wastewater-based epidemiology. The hourly composite raw wastewater (every 10 minutes) samples were collected for three consecutive days in a typical week (total of 72 samples), analyzed for target drug residues using UPLC-MS/MS, and back-calculated the consumption rate of …


Monitoring Lesser Known Harmful Algal Blooms On The Oregon Coast, Taylor Dodrill, Tawnya D. Peterson, Matthew Hunter, Micah Rogers Apr 2019

Monitoring Lesser Known Harmful Algal Blooms On The Oregon Coast, Taylor Dodrill, Tawnya D. Peterson, Matthew Hunter, Micah Rogers

OHSU-PSU School of Public Health Annual Conference

Ocean warming has expanded the niche of harmful algal blooms (HABs), including HABs previously believed to pose little risk of shellfish contamination in the Pacific Northwest. Monitoring efforts in Washington and California have demonstrated that Dinophysis spp. is a HAB of emerging concern and has been linked to diarrhetic shellfish poisoning events. However, quantitative monitoring for Dinophysis spp. on the Oregon Coast has been limited. This analysis provides a preliminary characterization of risk that Dinophysis spp. poses to shellfish consumers in Oregon. Furthermore, we assess the predator-prey interaction between Dinophysis spp. and its prey, Mesodinium rubrum, to determine whether …


Fluoride Removal From Water Using A 3d Printed Calcium Carbonate Filter, Sophia Bakar, David Kahler, Benjamin S. Goldschmidt Apr 2019

Fluoride Removal From Water Using A 3d Printed Calcium Carbonate Filter, Sophia Bakar, David Kahler, Benjamin S. Goldschmidt

Undergraduate Research and Scholarship Symposium

Groundwater containing high concentrations of fluoride is the most common source of drinking water in rural areas in parts of east Africa, India, and China. The elevated levels of fluoride cause skeletal and dental fluorosis, which is the weakening and decay of bone structures due to the leeching of calcium from the body as calcium and fluoride bond by the process of adsorption. Over 150 million people are suffering from some form of fluorosis due to the consumption of groundwater. Calcium carbonate has been demonstrated to influence fluoride removal in several forms. To make fluoride removal a cost-effective and user-friendly …
