Assessing The Impact Dynamics Of Less Lethal Ammunition, Steven Bermejo
Assessing The Impact Dynamics Of Less Lethal Ammunition, Steven Bermejo
Student Theses
Less-lethal ammunition is widely used by law enforcement as an alternative to lethal force during crowd control, on-street confrontations, and other situations requiring force. Although these projectiles are intended to reduce risk of fatal injury, serious injuries and fatalities have been reported, highlighting the need to better understand the factors that influence their impact behavior. This study evaluated the impact dynamics of four types of 12-gauge less-lethal ammunition, including rubber buckshot, single rubber ball, double rubber ball, and Byrna kinetic projectile, using kinetic energy calculations derived from projectile mass and velocity measurements. In addition, Attenuated Total Reflectance Fourier Transform Infrared …
Analysis Of Terpenes In Cannabis Flowers Using Gas Chromatography Via Headspace-Solid Phase Microextraction (Hs-Spme), Hannah I. Bergner
Analysis Of Terpenes In Cannabis Flowers Using Gas Chromatography Via Headspace-Solid Phase Microextraction (Hs-Spme), Hannah I. Bergner
Forensic Science Master's Projects
As cannabis commercialization grows, rigorous profiling of cannabinoids, terpenes, and chemical contaminants is legally required for industry standardization and consumer safety. Terpenes are highly volatile components that dictate the unique aromatic profiles and therapeutic properties of cannabis via receptor pathways. This project focused on a gas chromatography-flame ionization detector/mass selective detector (GC-FID/MSD) combined with headspace-solid phase microextraction (HS-SPME) sampling to analyze terpenes present in four cannabis samples. Cannabis samples were tightly sealed in vials (10 mL) and heated to vaporize terpenes in the headspace above the samples, followed by the extraction of the vaporized terpenes using a polydimethylsiloxane (PDMS)-coated SPME …
The Analysis Of Reference Standard Storage Failures Through The Use Of Ibuprofen, Hope Vonder Brink
The Analysis Of Reference Standard Storage Failures Through The Use Of Ibuprofen, Hope Vonder Brink
Honors Projects
Reference standards are commonly used in drug chemistry. They are used to calibrate the instruments and serve as a known point of reference for analysts’ ability to compare unknowns. Drugs can degrade over time or through environmental factors, causing contaminants to be present. In the event of environmental degradation while in storage, such as the exposure to high heat, it would be beneficial to have a database of known breakdown products in common drug reference standards for analysts’ reference. Using ibuprofen as an exemplar drug, this study attempted to identify the thermal breakdown products of ibuprofen and introduce the proposed …
