epistemic modality in english and persian academic writing: a cross-linguistic study of genre on the notion of transfer
چکیده حیطه ی نوشتار دانشگاهی اخیرا شاهد تغییرات عمده ای از غیرشخصی بودن (عینی بودن) به شخصی بودن بوده است. شخصی بودن متون دانشگاهی اهمیت استفاده از وجهیت معرفتی را برجسته می سازد چرا که? وجهیت معرفتی? بر اساس یکی از تعاریف ارائه شده از این مقوله? ارتباط تنگاتنگی با شخصی بودن داشته و به عنوان بیان نظر شخصی گوینده در مورد جز گزاره ای گفته در نظر گرفته میشود. بنابراین? با در نظر داشتن نقاط مشترک...
15 صفحه اولWind tunnel experiments of tracer dispersion downwind from a small-scale physical model of a landfill
Wind tunnel experiments have been carried out on a small-scale physical model of a municipal waste landfill (MWL) in the CRIACIV (Research Centre of Building Aerodynamics and Wind Engineering) “environmental” wind tunnel in Prato (Italy). The MWL model simulates a landfill whose surface is higher than the surrounding surface, applying a 1:200 scaling factor. Modelling an area source such as lan...
متن کاملEXPERIMENTAL INVESTIGATION OF EFFECTS OF WALL POROSITY AND SUCTION ON THE FLOW QUALITY IN A TRANSONIC WIND TUNNEL
A trisonic wind tunnel has been modified to improve its flow quality when operating at transonic speeds through perforated walls and side suctions. The usefulness of such a perforated wall, already known, is reduction of the blockage effect as well as the shock elimination. Two types of perforated walls have been used in this investigation. The first wall had a porosity of about 22% and the hol...
متن کاملAn Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel
Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...
