Co-Crystallization Of Urea Granules For Slower Dissolution, Vidya Nagaraju, Carl Wassgren, Kingsly Ambrose
Co-Crystallization Of Urea Granules For Slower Dissolution, Vidya Nagaraju, Carl Wassgren, Kingsly Ambrose
Graduate Industrial Research Symposium
Co-crystals are multicomponent crystals formed through hydrogen bond interactions. Co-crystallization, the process of developing cocrystals, serves as a versatile approach for discovering new solid forms of active ingredients (AIs) that can alter physical properties such as solubility, dissolution rates, and stability. These co-crystals can be produced through three main methods: solid-state methods, solution-based methods, and supercritical fluid methods. Recently, the solid-state (mechanochemical) method of developing cocrystals has gained more attention from researchers in the development of slow-release urea fertilizers. This technique can also be applied to the development of urease inhibitors. These multicomponent crystals present a potential solution to the …
Nucleic Acid Detection Of Live Pathogens On Contaminated Foods, Simerdeep Kaur, Mohit Verma
Nucleic Acid Detection Of Live Pathogens On Contaminated Foods, Simerdeep Kaur, Mohit Verma
Graduate Industrial Research Symposium
The goal is to develop a point-of-care biosensor for the detection of live pathogens contaminating beef products. Biosensing of live pathogens is based on isothermal amplification of nucleic acid on a paper-based device. A colorimetric dye is employed as an indicator of the amplification product for visual result. The assay incorporates a compound Propidium monoazide (PMA) that makes the DNA from dead cells inaccessible for amplification. This approach is especially applicable for pathogens that can enter a viable but non-culturable state (VBNC).

Behavioral Alterations Following Exposure To A Mixture Of Lead And Atrazine During Early Development In The Zebrafish Model System, Anusha Kv Lakshmi Dharmavathi
The Journal of Purdue Undergraduate Research
Lead (Pb) and atrazine (ATZ) are hazardous environmental toxicants that can exist as a mixture in potable water. Numerous single chemical studies on Pb and ATZ support adverse health outcomes, including neurotoxicity, but mixture studies are limited. Th e aim of this study is to test the hypothesis that Pb and ATZ mixtures result in a greater than additive toxicity, causing increased adverse health outcomes than single chemical exposures. Th e zebrafish model system was exposed to 3 or 30 ppb (µg/L) ATZ, 10 ppb (equivalent to 0.1 µg/dL) or 100 ppb Pb, along with mixtures of each beginning at …

Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward
Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward
Purdue Journal of Service-Learning and International Engagement
Engagement Methods for International Food Security (YDAE 49100) provided an opportunity for enrolled students to travel abroad to Cap-Haitïen, Haiti. As both a course in agriculture and a service-learning study abroad, the overarching goal was to inspire, engage, and teach Purdue and Haitian students through service learning in agriculture. This was done by developing a project with teammates during the fall semester that was then presented to students in Haiti during the International Agri-Symposium at Université Antenor Firmin over winter break.
Investigating Sociodemographic Disparities In Cancer Risk Using Web-Based Informatics, Hong-Jun Yoon, Georgia Tourassi
Investigating Sociodemographic Disparities In Cancer Risk Using Web-Based Informatics, Hong-Jun Yoon, Georgia Tourassi
Journal of Human Performance in Extreme Environments
Cancer health disparities due to demographic and socioeconomic factors are an area of great interest in the epidemiological community. Adjusting for such factors is important when developing cancer risk models. However, for digital epidemiology studies relying on online sources such information is not readily available. This paper presents a novel method for extracting demographic and socioeconomic information from openly available online obituaries. The method relies on tailored language processing rules and a probabilistic scheme to map subjects’ occupation history to the occupation classification codes and related earnings provided by the U.S. Census Bureau. Using this information, a case-control study is …
Full-Water Column Turbulence Parameterization Of Stratified Waters In Southern Lake Michigan, Kyla A. Prendergast, Cary D. Troy, David Cannon
Full-Water Column Turbulence Parameterization Of Stratified Waters In Southern Lake Michigan, Kyla A. Prendergast, Cary D. Troy, David Cannon
The Summer Undergraduate Research Fellowship (SURF) Symposium
Full water column mean flow and turbulence structure was characterized at two stratified locations in Lake Michigan (a. Muskegon, MI; b. Michigan City, IN) in order to better understand the filtration potential of invasive quagga mussels. Invasive quagga mussels in Lake Michigan are filter feeders and can dramatically alter clarity as well as the biological/chemical characteristics of the water column. This filtering capacity is highly contingent on turbulence characteristics throughout the water column, which is poorly understood in the Great Lakes. Using velocity, temperature, and turbulence data collected from these locations, the structure of the water column turbulence was modeled …

X-Ray Fluorescence For Quantification Of Lead And Strontium In Vivo, Aaron James Specht

Lead (Pb) is a toxicant well known for its effects on almost every organ system in the body. Pb use in industry has declined since removal of Pb from gasoline, but many developing countries still have significant use of Pb. Exposure to Pb has been linked with diseases causing neurodegeneration and thus have lasting effects long after the initial exposure. Another metal, strontium (Sr), has been linked with bone disease in particular situations and shown to have uses in treating osteoporosis as a supplement. However, there are no studies of the effects of Sr using a meaningful biomarker. The most …
