The Rotating-Stall (RS) through a rotor-cascade of an axial compressor were numerically investigated with an unsteady two-dimensional finite-volume density based computer code. To validate the computer code, a test case was prepared and the good agreement of the compared results has given the adequate assurance of the code. The RS was incepted with a 40% reduction in flow coefficient and a 0.4%...
اساس سیستمهای تصویربرداری ایکس پسپراکنده، پرتوهای بازگشتی هستند که در صنعت و بازرسی دارای کاربردهای بسیاری میباشند. این تصاویر برخلاف روش عبوری، مواد آلی با عدد اتمی پایین مانند مخدر منفجره پراکندگی فوتون بالا، واضحتر دیده میشوند. به علت چندگانه فوتونی معمولاً ماتشدگی دارند. پردازش خروجی میتواند بهبود کنتراست تشخیص کمک کند. تحقیق از وردش برای استفاده شده پرتونگارههای فانتومهایی ارزیابی...
The use of new methods, remote sensing (RS) and geographical information system (GIS) in zoning the water erosion in a particular geographical area (Tang-e-Bostanak catchment area) constitute the main subjects of this study. The production, combination, and composition of effective information layers in identifying these zones have been noted, highlighting the capacity of GIS and RS. In this st...
The structural complexity, especially canopy and gap structure, of old-growth forests affects the spatial variation of soil respiration (Rs). Without considering this variation, the upscaling of Rs from field measurements to the forest site will be biased. The present study examined responses of Rs to soil temperature (Ts) and water content (W) in canopy and gap areas, developed the best fit mo...
AIM The 21-gene recurrence score (RS) predicts a clinical benefit of chemotherapy for individuals with ER-positive/HER2-negative breast cancer. Using in vitro chemoresponse assay, we compared the chemosensitivity according to RS in these patients. METHOD Among the patients with Oncotype Dx assay, we identified 63 patients who had chemotherapy response assays to doxorubicin based on adenosine ...
Studying the responses of soil respiration (Rs) to soil management changes is critical for enhancing our understanding of the global carbon cycle and has practical implications for grassland management. Therefore, the objectives of this study were (1) quantify daily and seasonal patterns of Rs, (2) evaluate the influence of abiotic factors on Rs, and (3) detect the effects of soil management ch...
as a major consequence of medical interventions, quality of life (qol) is of great importance for patients suffering from refractory diseases, particularly cancer. the unbiased measurement of changes in qol is thus crucial in such cases. a prevalent bias related to qol research is the ‘response shift’ (rs) phenomenon. this review article aims to define rs and the challenges in measuring it. in ...
Winter soil respiration (Rs) is becoming a significant component of annual carbon budgets with more warming in winter than summer. However, little is known about the controlling mechanisms of winter Rs in dryland. We made continuous measurements of Rs in four microsites (non-crust (BS), lichen (LC), moss (MC), and a mixture of moss and lichen (ML)) in a desert shrub-land ecosystem northern Chin...
In vitro gas production was measured to investigate associative effects of untreated and chemically treated rice straw (RS) and of RS and grass hay or mulberry leaves (ML). The RS was treated with NaOH, urea, or (NH4)HCO3. Cumulative gas production was recorded at 2, 4, 6, 8, 12, 16, 24, 36, 48, 60, 72, and 96 h of incubation, and the Gompertz function was used to describe the kinetics of gas p...
BACKGROUND Allergic rhinitis (AR) and rhinosinusitis (RS) negatively impact psychological well-being and health-related quality of life (HRQoL). However, few population-based studies have investigated the effects of these conditions on mental health and HRQoL. PURPOSE To explore independent associations of AR and/or RS with mental health and HRQoL using data from the 2013-2015 Korea National ...
