I am grateful to many people who helped in the translation of these articles in various ways. Without the works of Alev, Koray, Nedim, Dilek, Aylin, Dilah, Asli, Emrah, Ufuk, Cuneyt, Cem, Zahide, Sahin and Esin, the translation of these articles would not have been completed. My heartfelt thanks go to all, both named and unnamed for their collaboration and unconditional service in spreading this science.
