Since both writers are relative newcomers to their literary scenes, the only bibliography available consists of brief reviews. The author hopes to give their work a wider audience so that divulgation will lead to more criticism and the attention they deserve. The literary references in these two writers are very indicative of their adopted cultures： Najat El Hachmi＇s favorites are mostly Catalan writers, while Laila Lalami speaks of American authors who lived in Morocco, and both mention traditional Arabic literature. The work of both these writers is greatly enriched, if sometimes painfully, by their absorption into multiple cultures and identities.展开更多

The experimental studies were performed within the Mach number range from 4 to 6 and Reynolds number 10-60×106 1/m, the angles of attack were 0° and 5°. The experiments were carried out on the three-dimensional convergent inlet model with and without sidewalls. The influence of artificial tubulator of boundary layer on transition and flow structure was studied. The conducted researches have shown that adverse pressure gradient increase hastens transition and leads to decrease of transition area length. If pressure gradient rises velocity profile fullness increases and profile transformation from laminar to turbulent occurs. As a result of it the decrease of separation area length occurs. The same effect was reached with Reynolds number increase. These results are compared with the data on two-dimensional model with longitudinal curvature.展开更多
