Forensic Analysis Of Automobile Paints By Atomic And Molecular Spectroscopic Methods And Statistical Data Analyses, Erin Mcintee
Forensic Analysis Of Automobile Paints By Atomic And Molecular Spectroscopic Methods And Statistical Data Analyses, Erin Mcintee
Electronic Theses and Dissertations
The analysis of 110 automotive paint samples was conducted for the research presented here. Laser-induced breakdown spectroscopy (LIBS) was the central instrument utilized for analysis although scanning electron microscopy / energy dispersive x-ray spectroscopy (SEM/EDS) and Fourier transform infrared spectroscopy - attenuated total reflection (FTIR-ATR) analyses were also performed. Two separate methods of LIBS analysis of samples were used: a cross sectional analysis and a drill down analysis. SEM/EDS analysis focused on the cross section while FTIR-ATR analysis concentrated on the clearcoat layer. Several different data/statistical analyses were evaluated including principal components analysis (PCA), two tailed t-tests based on several …
The Identification Of Ignitable Liquids In The Presence Of Pyrolysis Products: Generation Of A Pyrolysis Product Database, Joseph Castelbuono
The Identification Of Ignitable Liquids In The Presence Of Pyrolysis Products: Generation Of A Pyrolysis Product Database, Joseph Castelbuono
Electronic Theses and Dissertations
The fire debris analyst is often faced with the complex problem of identifying ignitable liquid residues in the presence of products produced from pyrolysis and incomplete combustion of common building and furnishing materials. The purpose of this research is to investigate a modified destructive distillation methodology provided by the Florida Bureau of Forensic Fire and Explosive Analysis to produce interfering product chromatographic patterns similar to those observed in fire debris case work. The volatile products generated during heating of substrate materials are extracted from the fire debris by passive headspace adsorption and subsequently analyzed by GC-MS. Low density polyethylene (LDPE) …
Geoarchaeological Investigations Along The Tambo-Ilo Coast Of Southern Peru, Louis Fortin
Geoarchaeological Investigations Along The Tambo-Ilo Coast Of Southern Peru, Louis Fortin
Electronic Theses and Dissertations
The south coast of Peru has had a long history of cultural occupancy from the Preceramic through Chiribaya periods, and into Spanish Colonial / Post-Colonial periods. Procurement and modification of lithic material was an important activity throughout each of these periods but remains an under-explored dataset for late Prehispanic and Colonial populations in the region. Analysis at the Cola de Zorro archaeological site and within the Tambo-Ilo region examined the relation cultures have with their environment through a geoarchaeological analysis of the local geology and the distribution of lithics. Surveys were completed at Cola de Zorro in the quebrada drainage, …
Chromatographic And Mass Spectral Analyses Of Oligosaccharides And Indigo Dye Extracted From Cotton Textiles With Manova And Ano, Jessica Frisch
Chromatographic And Mass Spectral Analyses Of Oligosaccharides And Indigo Dye Extracted From Cotton Textiles With Manova And Ano, Jessica Frisch
Electronic Theses and Dissertations
Research was conducted on thirteen 100% cotton denim samples using an acid wash, established by Murray, to extract oligosaccharides from the cellulosic material. The oligosaccharide ion groups (+, +, and +) for molecules with degrees of polymerization between two and seven (DP2-DP7) were analyzed using liquid chromatography coupled to mass spectrometry with an electrospray ionization interface (LC-ESI-MS). The results were compared using the least-squares means in a Multivariate ANOVA (MANOVA) test followed by Univariate ANOVA and Tukey HSD tests and demonstrated that the method could correctly determine that two samples were statistically different 85.9% of the time when analyzing the …
Development And Forensic Application Of Dye Probe Fluorescence Resonance Energy Transfer For Improved Detection Of Changes In Dn, Micah Halpern
Development And Forensic Application Of Dye Probe Fluorescence Resonance Energy Transfer For Improved Detection Of Changes In Dn, Micah Halpern
Electronic Theses and Dissertations
Discovering, screening, and associating changes in DNA sequence are important to a broad range of disciplines and play a central role in Forensic Science. The typical types of changes include sequence variations [single nucleotide polymorphisms (SNP)] and length variations [short tandem repeats (STR)]. The steps for forensic DNA sample processing are similar for both types of changes but diverge at the point of detection. A number of approaches are being explored for SNP genotyping while STR analysis primarily consists of size-based analysis by capillary electrophoresis. Limitations exist for all current detection methods that pose significant impacts to forensic analysis. Bi-allelic …
Toward A New Social Contract: A Tripartite Mixed-Methods Analysis Of Social Sustainability At Three Land-Grant Universities, Lyndsay Josephine Agans
Toward A New Social Contract: A Tripartite Mixed-Methods Analysis Of Social Sustainability At Three Land-Grant Universities, Lyndsay Josephine Agans
Electronic Theses and Dissertations
Increasingly, colleges and universities in the United States are adapting toward a model of behavior that incorporates issues of sustainability. This adaptation in universities and in society has implications on the organizational and nation-state level, the very core of which may serve to reshape the social contract between the two. In addition to supplying a strong counter-hegemonic argument that alters the competitive economic agenda-setting paradigm, this study serves as a tripartite comparative case study analysis of university adaptation toward social sustainability. By employing a social capital lens to understanding social sustainability in higher education, this study seeks to examine the …
