I am curious for the reasoning to put silver in the cartilage. I am also wondering how exactly do you results support previous studies?
Thank you for your questions!
As the cartilage is a biological sample it is coated in silver to make the sample conductive. Other highly conductive metals can be used for coatings (gold, copper, platinum, carbon etc) it just depends really on cost, what analysis is taking place and what is available.
This research results follow the general pattern of decomposition that has been recorded, visually (changes to the appearance and texture of the soft tissues) along with the decomposition of DNA. This research also supports the findings of previous studies conducted by Rogers (2014; 2011) and Bolton (2015) in rate of decomposition in different environmental conditions, the presence of crystals forming on the articular cartilage and the presence of bacteria. However, further work needs to be conducted on the identifying the bacteria and the chemical composition of the crystals and determining the crystals origin.
A very interesting study regarding PMI using articular cartilage. Any questions I had were answered in response to a previous commenter, so I will just give a couple of ideas/tips for future poster presentation regarding layout. Firstly, great use of images, that keeps it nice and clear and shows the audiences the changes, also well done on making the text easy to read when using a picture for the background (not an east feat to pull off). The flow of the poster is a little confusing as the reader will tend to read down and then across, which means that they would reach the results and conclusions before they get to the results. I understand that sometimes, for aesthetic purposes and positioning of images, the text just doesn't fit if you were to keep it in that order. This is where you need to look into the way the text is presented. The methodology section has a lot of spacing in it between points, which I am not sure are bullet points or supposed to be paragraphs (one of my examiners once pointed out to me'a sentence does not make a paragraph', I had a habit of doing this too even up to PhD level). If bullet points, then add hte points in there and you can get rid of the spacing, meaning the text will take up less space and enable you to get the flow right.
Overall though, a great project that shows promise and I look forward to hearing more about it in the future.
Hi Dr Davenport,
Thank you for your helpful comments, I will be sure to implement them in my next poster but I am glad to hear that you have enjoyed reading my first research poster.
