Elemental Analysis Of Adhesive Tapes By Laser-Based Methods, Claudia Martinez Lopez
Elemental Analysis Of Adhesive Tapes By Laser-Based Methods, Claudia Martinez Lopez
FIU Electronic Theses and Dissertations
Adhesive tapes are a common type of evidence involved in violent crimes and national security threats. This research evaluated the utility of LA-ICP-MS and LIBS for the characterization of the trace elemental signature in adhesive tapes for forensic comparisons. LA-ICP-MS and LIBS methods were developed, for the first time, for the qualitative and quantitative analysis of adhesive tapes.
The backings of 90 black electrical tapes, previously characterized by conventional techniques (physical examination, IR, Py-GC-MS, and SEM-EDS), were analyzed by LA-ICP-MS to evaluate the ability of the technique to discriminate samples originating from different sources and to associate pieces of tapes …

The Optimization Of Pressure Cycling Technology (Pct) For Differential Extraction Of Sexual Assault Casework, Vanessa Martinez
FIU Electronic Theses and Dissertations
A two-step protocol has been devised as a rapid and selective alternative to conventional differential extraction techniques with an increased recovery of DNA. The protocol involves pressure cycling with the Barocycler® NEP 2320 from Pressure Biosciences. Inc. in alkaline conditions for epithelial cell lysis and removal. This step is followed by alkaline lysis at 95º C for extraction of sperm cell DNA. At 1:1 or 2:1 female to male cell ratios, high selectivity and complete separation can be achieved. But at higher ratios, male allelic dropout is observed. This protocol has been modified to generate a clean male …

Identification Of Characteristic Volatile Organic Compounds Released During The Decomposition Process Of Human Remains And Analogues, Norma Iris Caraballo
FIU Electronic Theses and Dissertations
The manner in which remains decompose has been and is currently being researched around the world, yet little is still known about the generated scent of death. In fact, it was not until the Casey Anthony trial that research on the odor released from decomposing remains, and the compounds that it is comprised of, was brought to light. The Anthony trial marked the first admission of human decomposition odor as forensic evidence into the court of law; however, it was not “ready for prime time” as the scientific research on the scent of death is still in its infancy.
