I have not heard of either of those but when someone in my apt building passed and was not found for a LONG time they purchased these little tubs, that had foam in them. The foam had environmental agents to clean our air and that also eliminated the odors... I hope you can find something that works that well!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
