Detecting Gsr Indicative Particles On Decayed Bones Using A Novel Field Kit, Sven Engling
Detecting Gsr Indicative Particles On Decayed Bones Using A Novel Field Kit, Sven Engling
Student Theses
Decomposed human remains are complex forensic puzzles, escalating in difficulty as the remains’ age obscures evidence, like trauma. Research has shown that scanning electron microscopes with energy dispersive X-ray spectrometers (SEM-EDX) are capable of detecting and identifying gunshot residue (GSR) particles on bones. However, SEM-EDX work is time consuming, expensive, and not accessible to every forensic department. Therefore, a preliminary field test capable of detecting GSR indicative particles, like lead, could save departments money and assist in trauma identification. This study examines the viability of using either the 3M Lead Check Test swabs or a sodium rhodizonate solution as part …
A Preliminary Investigation Into The Effects Of Lucilia Sericata (Meigen) Blow Fly Larval Feeding On Sharp Force Trauma (Sft) Wound Patterns In Decomposing Bones Of Sus Scrofa Domesticus, Erica L. Klafehn
Student Theses
An important aspect of forensic investigations involves the characterization and analysis of bone related trauma as this can provide valuable information regarding the manner and circumstances of death. Bone trauma can be classified into three main categories, which include Sharp Force Trauma (SFT), Blunt Force Trauma (BFT), and Gunshot Trauma. Previous experiments have explored SFT on flesh and bones, specifically made with knives or saws, coupled with various microscopic analytical methods. Minimal research has been done integrating both a forensic entomology and forensic anthropology approach, so it is imperative to understand previous literature detailing the behaviors of insects (blow flies), …
Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty
Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty
Student Theses
Simple methods to aid in the determination of forensic or archaeologic relevancy of skeletonized remains have been researched since the 1950s. With advances in microscopic imaging techniques and machine learning computer data analysis methods the relevancy of decontextualized, comingled remains has room for improvement. This thesis is a study done to pioneer a new approach to analyzing dental skeletal remains to determine forensic relevancy.
Archaeological dental samples collected from the ancient city of Ur in modern day southern Iraq in addition to modern dental extractions were processed for scanning electron microscopy imaging. Archaeological and modern samples displayed different surface and …
The Sound Of Bone: The Initial Testing And Analysis Of Sound As A Species Identification Method For Osteological Remains, Emily J. Dunn
The Sound Of Bone: The Initial Testing And Analysis Of Sound As A Species Identification Method For Osteological Remains, Emily J. Dunn
Theses and Dissertations
This paper represents a preliminary test to an alternative method of species remains identification, namely bone acoustics. It is hypothesized that human and non-human long bone remains of similar diameter produce different amplitudes of sound from one another, resulting in the ability to distinguish human remains from non-human remains.
