German to Turkish Law/Patents Law (general) Criminal law

Apologies for explaining in English. This term has been posted as a German to English question here:
http://www.proz.com/kudoz/german_to_english/law_general/5126...
Personen [...] können mit zehnjähriger erschwerter Haft belegt werden [...].

Suggestions in so far include aggravated/rigorous/heavy/tightened/difficult imprisonment.
It would be useful to find out what the original Turkish says, in particular to find out whether the first of these two words really is a past participle form (if such a thing exists in Turkish) or just an adjective. It would also be good if you were able to suggest a suitable English translation.
Thanks for your help
