Behavior of unsaturated pelitic soil in a railway context

Unsaturated railway track-bed materials

Railway track-bed materials are mostly in unsaturated state, and their hydro-mechanical properties depend strongly on their water contents or suctions. In France, problematic soils such as collapsible loess and swelling marl can be origin of instability problems for new lines for high speed trains, while the hydro-mechanical behaviour of interlayer soil formed mainly by interpenetration of ball...

Behavior of Unsaturated Layered Soil Columns during Infiltration

This paper presents the laboratory test results of vertical infiltration on two soil columns of finer over coarser soils subject to simulated rainfalls under conditions of no-ponding at the surface and constant head at the bottom. The main objectives were to evaluate the effect of rainfall intensity and duration; and to provide experimental evidence for soil water redistribution and hysteresis....

norms and ideology in translation of children literature in persian context

اهداف عمده ی این مطالعه دو دسته هستند:1) تعیین هنجار های اجتماعی فرهنگی مورد استفاده در ترجمه ی کتاب کودک برای کودکان ایرانی 2) بررسی مفهوم کودک در ایران و ائدئولوژی این جامعه در رابطه با کودک که مترجم را مجبور به بازسازی کتابهای داستان برای کودکان ایرانی میکند. به این منظور, ابتدا ,مجموعه ای از 30 کتاب داستان و ترجمه های فارسی انها بر اساس مدلlambert and van gorp(2006)مقایسه شد و سپس استراتژیه...
