Oxygen-limited autotrophic nitrification/denitrification (OLAND) is a one-stage combination of partial nitritation and anammox, which can have a challenging process start-up. In this study, start-up strategies were tested for sequencing batch reactors (SBR), varying hydraulic parameters, i.e. volumetric exchange ratio (VER) and feeding regime, and salinity. Two sequential tests with two paralle...
هدف از این مطالعه امکان سنجی تابش دهی سوخت میله ای UO2با غنای 5-3 درصد در راکتور تحقیقاتی تهران و بررسی معیارهای ایمنی از دیدگاه نوترونیک در شرایط بهره برداری راکتور می باشد. مجتمع سوخت کنترل میله ای دارای 12 میله سوخت به قطر خارجی cm36/1 وگام cm633/1بهصورت 4 3 می باشد. ابتدا به منظور تجزیه و تحلیل ارزش راکتیویته ی مجتمع سوخت میله ای، بارگذاری مجتمع سوخت میله ای با غنای 5-3% به قلب مرجع راکت...
مطالعه حاضر جهت بررسی اثربخشی درمان هفت مرحله ای فورتین بری و موری در بهبود افسردگی، اضطراب و تنیدگی دانشجویان طراحی گردید، جامعه آماری این پژوهش را دانشجویان زن مقیم خوابگاه های دانشگاه علامه طباطبائی تشکیل میدادند نمونه آماری شامل 23 دانشجوی 19 تا 26 ساله بود که به روش نمونه گیری در دسترس براساس پرسشنامه افسردگی بک، افسرده تشخیص داده شده بودند و موافق شرکت در این نوع از درمان بودند به طور تصا...
A successful enhanced biological phosphorus removal (EBPR) was observed in both anaerobic-aerobic sequencing batch reactor (An-Ox SBR) to induce growth of phosphorus accumulating organism (PAO) and anaerobic-anoxic (An-Ax) SBR to induce growth of denitrifying PAO (DPAO). Although the EBPR performance of An-Ox SBR was higher by 11.3% than that of An-Ax SBR, specific phosphorus release rates in t...
PURPOSE Massive small bowel resection (SBR) results in an adaptive response within the remnant bowel. We have previously shown an immediate reduction in intestinal blood flow and oxygen saturation (sO2) after SBR. We therefore sought to determine the duration of resection-induced intestinal hypoxia and expression of hypoxia-inducible factors (HIFs) following SBR. METHODS C57B6 mice were subje...
PURPOSE Massive small bowel resection (SBR) results in villus angiogenesis and a critical adaptation response within the remnant bowel. Previous ex vivo studies of intestinal blood flow after SBR are conflicting. We sought to determine the effect of SBR on intestinal hemodynamics using photoacoustic microscopy, a noninvasive, label-free, high-resolution in vivo hybrid imaging modality. METHOD...
To improve the performance of concrete, polymers are mixed with concrete. It has been observed that polymer-modified concrete (PMC) is more durable than conventional concrete due to superior strength and high durability. In this research, effect of Styrene-Butadiene Rubber (SBR) latex on compressive strength and flexural strength of concrete has been studied and also the optimum polymer (SBR-La...
BACKGROUND The somatosensory evoked blink response (SBR) is a characteristic reflex blink elicited by electrical stimulation of peripheral nerves or other anatomical sites. METHODS 139 patients with neurological disorders were examined for presence of the SBR. Although the SBR was not usually elicitable, it was present in a subset of patients with Parkinson's disease and with hemifacial spasm...
We consider two generalizations of signed Sorting By Reversals (SBR), both aimed at formalizing the problem of reconstructing the evolutionary history of a set of species. In particular, we address Multiple SBR, calling for a signed permutation at minimum reversal distance from a given set of signed permutations, and Tree SBR, calling for a tree with the minimum number of edges spanning a given...
The effects of two types silanes, which were bis (triethoxysilylpropyl) tetrasulfide (Te) and octyltriethoxysilane (Oc), on the extrusion properties styrene-butadiene rubber (SBR) /silica (Si) composite investigated from viewpoint bound rubber. surface roughness SBR extrudate slightly increased when adding Te, didn't increase Oc. On other hand, for SBR/Si composites was smooth, it hardly change...
