I am currently about to finish my doctoral thesis (hurray!) just to find out that I forgot to ask for permission to some of the figures I used to illustrate it, mostly schemes for the introduction. I could easily find the way to ask for it for those figures present in scholarly publications, all free of charge and I was glad to see that the option was quite straightforward to find… except for one of them.
The following link contains a handbook explaining basic aspects for crosslinking techniques, and there are very nice and clear figures, one of which I am using to illustrate the section of my thesis regarding the conjugation:

The figure is very clear and I don’t think I could do it better than they did, so I would like to ask for permission to reproduce it, but I cannot find any option neither on the document nor in the website itself!
Any ideas? I am emailing them as I finish writing this, but I am worried they may take some time to reply to something easy to solve.
