Combined chemical and optical methods for monitoring the early decay stages of surrogate human models
Statheropoulos, Miltiades K.; Agapiou, Agapios; Zorba, Eleni; Mikedi, Katerina; Karma, Sofia; Pallis, George C.; Eliopoulos, C.; Spiliopoulou, C. (2011)As the body decays shortly after death, a variety of gases and volatile organic compounds (VOCs) constantly emanate. Ethical and practical reasons limit the use of human corpses in controlled, time-dependent, intervening ...
