Stratospheric Effects On Uv, Speed Of Sound, Pressure, And Temperature, Joshua V. Chis, Joana Diaz, Brianna E. Ortiz, Imani G. Robertson, Jelani A. Shadd Jul 2022

Stratospheric Effects On Uv, Speed Of Sound, Pressure, And Temperature, Joshua V. Chis, Joana Diaz, Brianna E. Ortiz, Imani G. Robertson, Jelani A. Shadd

The atmosphere is composed of several layers, each with its own distinct environment varying in temperature, pressure, and levels of UV radiation. Quantifying these varying parameters proves to be useful in understanding atmospheric composition in greater detail. Variance in the composition of the atmosphere allows for the study of the evolution of physical phenomena at different altitudes. Our group quantified this variance using a high-altitude weather balloon and designed an experimental method to observe the nature of sound propagation through varying altitudes. The goal was to develop an altitude-dependent model of the speed of sound by using an open-air, microcontroller-based …


What's In Your Soil? A Comparative Assessment Of Total Lead In Soils In Southwest Side And North Side Chicago Communities, Jennifer Garcia Jul 2022

What's In Your Soil? A Comparative Assessment Of Total Lead In Soils In Southwest Side And North Side Chicago Communities, Jennifer Garcia

DePaul Discoveries

In Chicago, city officials continue to locate polluting industries in predominately Black and Hispanic/Latinx neighborhoods. Lower income families are disproportionately exposed to greater amounts of toxic chemicals such as lead (Pb). While the City of Chicago focuses its effort in removing industrial sites from the North Side, a predominately white community area, sources of industrial pollution are more likely to be found in communities of color. Due to the prevalent sources of Pb on the Southwest side, residential soil is often highly disturbed and contaminated. Pb is a serious neurotoxin, and ingestion or inhalation of Pb contaminated soil and dust …


Atmospheric Phosphorus Deposition Into A Fresh Water Wetland: Prairie Wolf Slough Restored Wetland, Isaac B. Daitzchman Jul 2022

Atmospheric Phosphorus Deposition Into A Fresh Water Wetland: Prairie Wolf Slough Restored Wetland, Isaac B. Daitzchman

Phosphorus is a major element needed for plant growth. Excess phosphorus from agricultural runoff and urban stormwater can enter waterways, resulting in growth of toxic algal blooms that are deleterious to local fauna. One way to remove phosphorus is by diverting agricultural and urban runoff into wetlands. One such wetland is Prairie Wolf Slough (PWS), located in north suburban Chicago, IL. Stormwater enters PWS through an inlet channel and exits through an outlet pipe into the Chicago River. A 16-year study documented that a significantly greater mass of phosphorus leaves PWS than enters through the inlet. This study accounted for …


Synthesis Of Triaminopyrimidine Derivatives For Inhibition Of Inflammatory Caspases, Marianna C. Haddad, Caitlin Karver Jul 2022

Synthesis Of Triaminopyrimidine Derivatives For Inhibition Of Inflammatory Caspases, Marianna C. Haddad, Caitlin Karver

DePaul Discoveries

Caspases are cysteine-dependent aspartic proteases whose functions are connected to different mechanisms of cell death and inflammation. As caspase-1 plays a significant role in the immune response, its activity has been of interest as a target for inhibitor development as its inhibition will reduce the levels of pro-inflammatory cytokines in inflammatory diseases, thus minimizing the symptoms that arise and serving as a possible therapeutic approach. Prior work discovered a family of potent inhibitors of caspase-1 with a common triaminopyrimidine scaffold. To further explore structure-activity relationship profiles of potential inhibitors of caspase-1, two different syntheses were attempted to create two new …


Optimization Of Dye Molecules For Use In Studying Inflammatory Caspase Enzymes, Josiah D. Stewart, Phasu Sirinit Jul 2022

Optimization Of Dye Molecules For Use In Studying Inflammatory Caspase Enzymes, Josiah D. Stewart, Phasu Sirinit

DePaul Discoveries

Inflammatory caspases are important enzymes in the initial immune response to pathogens. A common method of studying caspase activity is through the use of fluorogenic assays, in which the cleavage of a substrate by an enzyme results in the emission of fluorescence. Fluorogenic assays require the use of fluorophores: molecules that will fluoresce upon the cleavage of a substrate. Different fluorophores have different characteristics, and these characteristics can be analyzed in order to determine which fluorophores will be most suitable for activity assays. Two commercially available fluorophores were compared for use in fluorogenic assays of inflammatory caspases: MCA and EDANS. …
