The Ability Of Vitreous Metabolite Concentration To Determine Time Of Death, Victoria Wiggins May 2020

The Ability Of Vitreous Metabolite Concentration To Determine Time Of Death, Victoria Wiggins

Themis: Research Journal of Justice Studies and Forensic Science

This paper analyzes the ability of vitreous fluid to determine time of death. The high variability in current methods used to establish post-mortem interval (PMI), or the amount of time between death and post-mortem examination make it difficult to obtain an accurate estimation. The concentration of metabolites found within vitreous fluid, such as potassium (K+), hypoxanthine (Hx), and magnesium (Mg), are the most researched alternatives to traditional methods in PMI determination because of the relative isolation of vitreous within the body and its ability to withstand degradation. There is no clear consensus on which metabolite provides the most accurate data …

SWITCH

A description of three three projects having to do with virtual reality. The first is the Nanomanipulator, developed at the University of North Carolina Chapel Hill Department of Computer Science in conjunction with the UCLA Department of Chemistry in 1991. It is a machine that allows the user to interact with microscopic particles previously only visible in 2D from an electron microscope. The second project, The Augmented Reality Project, also developed at the Chapel Hill Department of Computer Science. This device used ultrasound images to be placed over a body allowing the user to see inside of it. The final …
