il-32 and tnf? are important cytokines in autoimmune and inflammatory diseases. il-32 has not been previously studied with respect to ms. here, we report il-32 and tnf? transcript levels in peripheral blood mononuclear cells of ms patients and control individuals by real time pcr. a significant difference in il-32 and tnf? mrna levels of patients as compared to controls was not observed. howeve...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...
The use of waste materials in road construction is becoming widely spread due to economic and environmental needs. Construction demolition mining residues have been studied for a long time. However, the fine materials, mainly from mine tailing residue, still complex, as they can be used inert into mix or become reactive agent geopolymer mixes. In present paper, an experimental application basal...
Preliminary layout design of buildings has a substantial effect on the ultimate design of structural components and accordingly influences the construction cost. Exploring structurally efficient forms and shapes during the conceptual design stage of a project can also facilitate the optimum integrated design of buildings. This paper presents an automated method of determining column layout desi...
