Remarks
Since July 2018, PQR is replaced by EPPO GD Desktop. -- To install and update GD Desktop, an Internet connection will be needed in the EPPO Global Database: https://gd.eppo.int/ . -- The EPPO Secretariat plans to release updates of GD Desktop every 3 months. It should be reminded to all users, that as GD Desktop cannot be updated in real-time, the online version (EPPO Global Database) should be used to obtain the latest information. -- Pitt Quantum Repository ws covered by Thomson Reuters Data Citation Index.
