پساب بسیاری از صنایع حاوی غلظت بالایی از نیترات (no3 >1000 mg/l) و ترکیبات آلی سمی می باشند. تخلیه نیترات به منابع آب های پذیرنده می تواند سبب آسیب های جدی به محیط زیست و مشکلات بهداشت عمومی گردد. هدف از این مطالعه بررسی کارایی بیوراکتور سیکلی دارای بستر متحرک (crbr) جهت دنیتریفیکاسیون غلظت های بالای نیترات با استفاده از ترکیب آلی سمی می باشد. اثر هر یک از متغییرهای غلظت اولیه نیترات، زمان ماند...

Night vision goggles (NVG’ s) are being used increasingly in military and civilian environments. Despite the use of these devices, relatively few tests exist to assess visual performance through NVG’ s. Hyperacuity tasks may provide a sensitive index of performance through night vision devices. In this study, grating vernier acuity was measured through NVG’ s. AS reported previously, a power la...

The existence of triplewhist tournaments for v players has recently been solved for all values of v except v = 17. For v = 12 and v = 13 a complete enumeration has shown the nonexistence of TWh (v), while constructions of TWh (v) have been presented for v > 17. For several values of v existence has been shown by constructing a TWh (v) with a prescribed, usually cyclic, automorphism group. In th...
