Perfect prognosis statistical downscaling relies on the relationships established using observational data for predictands and predictors. Predictors are often retrieved from reanalyses, which considered pseudo-observations. The impact of choice a reanalysis dataset performance method is usually overlooked, as global reanalyses frequently assumed to be equivalent last few decades data-rich regi...
Cobalt-based superalloys are common materials for the manufacturing of various components used in aerospace applications. Conventional cobalt-based with a unimodal grain structure generally exhibit low strength and ductility at high temperatures. A bimodal superalloy, Co–20Cr–15W–10Ni (CCWN), was designed to achieve both The deformation behavior tensile properties CCWN alloy fine-grain (FG), co...
ایجاد ترکیب سرمتی Cr3C2-NiCr توسط فرایند پاشش سوخت-اکسیژن سرعت بالا (HVOF) منجر به انحلال بخشی از فازهای Cr3C2 در آلیاژ NiCr و افت سختی و مدول الاستیک پوشش میشود. در این تحقیق، پودر Cr3C2-25wt% (Ni-20Cr) توسط فرایند HVOF روی زیرلایههایی از جنس سوپر آلیاژ Hastelloy X اعمال شدند. تأثیر عملیات حرارتی بر بازیابی فاز Cr3C2و بهبود سختی و مدول الاستیک پوشش مورد بررسی قرار گرفت. بدین منظور، بررسی ری...
The quantitative estimation of urinary 5P-pregnane-3&, 17a, 2Ocr-trio1 has become of interest, since it is frequently excreted in excessive amounts by patients with adrenocortical hyperplasia or adrenal tumors (reviewed (1)). The related 11-ketosteroid, 5&pregnane-Sa!, 17a, 20a-triol-11-one is often of greater biochemical interest since it has been isolated and estimated so far only in the urin...
The effect of steroid substrate addition on the visible absorption and electron spin resonance (ESR) properties of cytochrome P450 was studied in bovine adrenal cortex submitochondrial particles. The interaction of ll-deoxycortisol or deoxycorticosterone produced peaks at 385, 500, and 645 nm and troughs at 420, 535, and 570 run. 2OarHydroxycholesterol produced opposite spectral effects. llDeox...
