Advances In Fire Debris Analysis, Mary Williams
Advances In Fire Debris Analysis, Mary Williams
Electronic Theses and Dissertations
Fire incidents are a major contributor to the number of deaths and property losses within the United States each year. Fire investigations determine the cause of the fire resulting in an assignment of responsibility. Current methods of fire debris analysis are reviewed including the preservation, extraction, detection and characterization of ignitable liquids from fire debris. Leak rates were calculated for the three most common types of fire debris evidence containers. The consequences of leaking containers on the recovery and characterization of ignitable liquids were demonstrated. The interactions of hydrocarbons with activated carbon during the extraction of ignitable liquids from the …
Analysis Of Mitochondrial Dna Coding Region Snps By Pyrosequencing, Kyle Robert Carl Parker
Analysis Of Mitochondrial Dna Coding Region Snps By Pyrosequencing, Kyle Robert Carl Parker
Electronic Theses and Dissertations
To date, the use of mitochondrial DNA in forensic analysis has relied on the presence of variations in the control region to differentiate between samples. One problem that this analysis has shown is the occurrence of common Haplogroup H haplotypes or identical sequences. Thus, there is a need to enhance the distinguishing power of this type of analysis. One option has been to investigate the mitochondrial coding region for polymorphisms that could differentiate between samples with identical control region haplotypes. The goal of this study has been to identify polymorphic coding region sites for development in a Pyrosequencing assay that …
Forensic Analysis Of C-4 And Commercial Blasting Agents For Possible Discrimination, Katie Steele
Forensic Analysis Of C-4 And Commercial Blasting Agents For Possible Discrimination, Katie Steele
Electronic Theses and Dissertations
The criminal use of explosives has increased in recent years. Political instability and the wide spread access to the internet, filled with "homemade recipes," are two conjectures for the increase. C-4 is a plastic bonded explosive (PBX) comprised of 91% of the high explosive RDX, 1.6% processing oils, 5.3% plasticizer, and 2.1% polyisobutylene (PIB). C-4 is most commonly used for military purposes, but also has found use in commercial industry as well. Current methods for the forensic analysis of C-4 are limited to identification of the explosive; however, recent publications have suggested the plausibility of discrimination between C-4 samples based …
