Direct numerical simulation (DNS) of a turbulent boundary layer (TBL) subjected to adverse pressure gradient (APG) at Reτ = 834 is performed to investigate large-scale influences on vortical motions. For comparison, DNS data of a zero pressure gradient (ZPG) TBL at Reτ = 837 is analyzed. The spanwise energy spectra of the streamwise velocity fluctuations show that the large-scale energy above 4...

After the fall of the Roman Empire in AD 476, scientific progress in Europe had come to a standstill. This era between fall of Rome and the Renaissance is commonly known as the dark ages. However, from the 8th till 13th century, scientific and cultural knowledge had flourished in the Islamic world. This period, which began soon after the establishment of the Abbasid Khalifate in Baghdad in the ...

This is a compilation of historical information from various sources, about the number i = √ −1. The information has been put together for students of Complex Analysis who are curious about the origins of the subject, since most books on Complex Variables have no historical information (one exception is Visual Complex Analysis, by T. Needham). A fact that is surprising to many (at least to me!)...

In this article, the use of art and literature as language religious education has been researched evaluations related to subject have given. People did not establish their communication with each other only in prose verbal, but they used a means interaction. Investigation whether there are interaction languages apart from speech makes study important. study, which was carried out reveal import...

Etiyopya ulusal efsanesinin konu edildiği Kebra Nagast’a göre Zagwe Hanedanlığı, Tanrı’nın yasasını çiğnemek suretiyle İsrail soyuna ait olan tahtı ele geçirmiş, Aksum Krallığı ve Süleyman Hanedanlığı arasında ara bir dönem oluşturmuştur. Taht meşruiyetinin tamamen soyu öncelediği bu koşullarda Hanedanlık için de ata hikayeleri ortaya çıkmıştır. Nitekim halk Nagast’ın anlatısına ekleme tarzda o...
