Here are three more examples of how to use Henssge's nomogram. Please note, there are two different nomograms based upon the ambient air temperature- one for 32 C and above and another for 32 C and below.

    Hi Brian, can you kindly explain why in your other Nomogram video, you looked up the corrective factor for 50 kg and multiplied them together (50 kg * 1.2 = 60 kg), before you looked on the semicircles for the time of death for 60 kg bodies, but in this video you just took the 80 kg weight of the body and went straight to looking for time of death on the semicircles, without doing the corrective factor first? Thank you so much

    how does is the graph affected by the bed temperature

    • @bbollone
      @bbollone 4 роки тому

      Not sure how bed temperature affects TSD however, use the corrective factors for layers of clothing (2.4, bedspread + clothing) per chart attached: docs.google.com/file/d/0By2F4CLPbpKmOTJmMTYzNDItMTdkMC00MzA1LWFmZDctZDAyNWUxYjIyZTk4/edit

    I haven't undestood how apply the corrective factor for body max. Where does the correttive index 1.2 come from?

    • @bbollone
      @bbollone 5 років тому

      Multiply the mass of the victim by the corrective factor which best fits the environmental condition in which the body is found. Here is a link to the corrective factors: www.swisswuff.ch/calculators/todeszeit.php

    Couple of things to add - there are two different nomograms, one for >23°C ambient and one for <23°C. Usability is pretty limited for >23°C. The body weight means the corrected bodyweight. Factors inhibiting cooling make the body cool "as if it was more heavy" (clothing, covering), factor >1.0. Factors promoting cooling will do the opposite (air movement, waterflow,...), with factors <1.0. Factor one (unchanged) would be unclothed, face up, no air movement. Corrective factors will add uncertainty , therefore different 2SD for use of CF or not. CF are further corrected themselves for reasons of allometric scaling. Basically putting a few blankets on a normal person might double its virtual body weight, while putting it on a very heavy person will not turn this person into a small elephant. There is an area where the line will hit nothing. That is when the body has cooled down too much. The different areas on the outer ring reflect Q (the left side of the equation) from 1 to 0.5; 0.5 to 0.3 and 0.3 to 0.2. What you must understand is so cool about the Nomogram is that a) you could do the more or less complicated math on the crime scene with no equipment b) corrective factors made it adaptable to all kinds of scenarios and c) because a lot of dummy experiments were conducted, the standard error and therefore the standard deviation is given. A feature that virtually no other algorithm has. +/-- 7 hours is a big window, but after all it is about sending a guy to prison or not. One last thing: the Prof. is called Henssge (hunsga for the american tongue *g*), or correctly Henßge with a german sharp S. Very nice guy and a source of both knowledge and inspiration.

      Thank you for the information. The examples I give in this video are for illustrative purpose, only. And, my target audience is high school students (grades 10-12) who are seeing this time of death model/method for the first time. I've watch parts of the lecture/video you shared, and appreciate your willingness to share your knowledge with me.

    Neat ! So when a robo Uber car shows up with a dead body in it I might be able to figure the time of death from the inside temp of the car and other factors with this nomogram?
