The Return of Reverse Gematria Madness (ADFM - ALLM search results Drop 1 of 2)

If you don't know what mean by 'Reverse Gematria', it's essentially where I take a group of numbers, either from a phone number I see, or any group of numbers and then use those numbers with a Gematria cypher, to get a group of letters and then I do a Google search with the results and see what turns up?
Every other time, has come up with some extremely interesting results and this time is no exception.
So the group of letters I got was:

AOE - DCLB - ADFM - ALLM

So I took those and divided them into 2 groups, the first was, 'AOE - DCLB', which turned up with nothing.
So then I tried:

ADFM - ALLM

Which produced these 14, rather intriguing results ranging from papers on nanomaterials and peptide medicines and more

The Return of Reverse Gematria Madness: DCLB - ALLM and DCLB - ADFM search results

Seeing as I'd only got any success with one group, I thought I'd try:

DCLB

with each of the other groups of 4 letters and hot some very surprising results, particularly with the, 'DCLB - ALLM', group that despite not really coming up with too many downloadable pdf files, it did come up with the following links:
