UNLV Theses, Dissertations, Professional Papers, and Capstones
An experiment was conducted to test the effects of evidence complexity and laboratory type on jurors' perceptions of forensic evidence. The study specifically focused on three types of labs: public labs, private labs, and "corporate labs." Public labs are managed by a federal, state, or local law enforcement agency, where evidence is usually analyzed internally at an agency. Private labs are those that have been formed as private businesses to provide services to federal, state, and local crime labs with overflow work. Corporate labs are managed by major retail corporations, and primarily service the needs of their store businesses, but …

Optimization Of The Microprecipitation Procedure For Nuclear Forensics Applications, Lyndsey Renee Kelly
UNLV Theses, Dissertations, Professional Papers, and Capstones
Microprecipitation has become one of the most widely used sample preparation techniques for alpha spectroscopy. Many factors during the precipitation process can affect the yield and energy resolution by adding unwanted mass to the sample. Current applications in nuclear forensics call for an optimization of energy resolution and yield in order to improve identification and quantify specific radionuclides. The purpose of this research is to determine the optimal parameters used for microprecipitation. The optimal solution temperature, precipitation time, carrier amount, and hydrofluoric acid amount are used to investigate the influence of varying the type of carrier, as well as, the …
