Will the bond proceeds always be greater than the face amount of the bonds when the contract rate is greater than the market rate of interest? Once the image is produced, it can be manipulated and enlarged. It is necessary to weigh the glue, in the boat before and after the fuming process. If the CA chamber is used for successive batches of evidence immediately upon removing items from a prior cycle, the heat source will still be warm and the time of exposure may have to be changed to prevent over-fuming in the subsequent cycles. Cyanoacrylate fuming is a chemical method for the detection of latent fingermarks on non-porous surfaces such as plastic, glass, rubber bands, finished and unfinished wood etc. You cannot paste images directly.
