Raisins are popular snacks with a favourable nutrient profile, being high in dietary fibre, polyphenols and a number of vitamins and minerals, in addition to being rich in fructose. In light of evidence demonstrating improvements in glycaemic control with moderate fructose intake and low-glycaemic index (GI) fruits, our aim was to determine the GI, insulin index (II) and postprandial responses ...
A protocol is prescribed for clinical reference dosimetry of external beam radiation therapy using photon beams with nominal energies between 60Co and 50 MV and electron beams with nominal energies between 4 and 50 MeV. The protocol was written by Task Group 51 (TG-51) of the Radiation Therapy Committee of the American Association of Physicists in Medicine (AAPM) and has been formally approved ...
Using a statistically representative sample of 911 central galaxies (CENs) from the SDSS DR4 Group Catalogue, we study how the structure (shape and size) of the first rank (by stellar mass) group and cluster members depends on (1) galaxy stellar mass (Mstar), (2) the global environment defined by the dark matter halo mass (Mhalo) of the host group, and (3) the local environment defined by their...
An analytical expression for R50% dependent on PTV surface area and volume: A cranial SRS comparison
This paper presents a research study of expected precipitation extremes across the Gandaki Province, Nepal. The used five indices to assess extreme under climate change. Precipitation output two Global Climate Models (GCMs) Coupled Model Intercomparison Project Phase Six (CMIP6) were characterize future during rainfall season from June September (JJAS) and overall days year. To events, we daily...
This study seeks to compare fixed-field intensity-modulated radiation therapy (FF IMRT), RapidArc (RA), and helical tomotherapy (HT) to discover the optimal treatment modality to deliver SBRT to the peripheral lung. Eight patients with peripheral primary lung cancer were reviewed. Plans were prescribed a dose of 48 Gy and optimized similarly with heterogeneity corrections. Plan quality was asse...
سایش چرخ و ریل در وسایل نقلیه ریلی غیر قابل اجتناب است. پژوهشگران در طول سالهای گذشته تلاشهای فراوانی برای کمینه سازی میزان سایش انجام داده اند. یکی از پارامترهای مهم، هماهنگی پروفیل و مشخصات چرخ با پروفیل و مشخصات ریل است. در خطوط ریلی کشور سه نوع غالب پروفیلهای ریل عبارتند از،u33 و uic60 که با شیب زیر ریل 1/20مورد استفاده قرار گرفته اند. در این مقاله این سه نوع پروفیل ریل با پروفیل چرخ s1002 ...
