در این پژوهش نمونه های نانو ساختار هیدروکسی اپتایت با قرار گرفتن در مجاورت گاز ? co?_2 در زمانهای 30و120 و 360 دقیقه تحت درجه حرارت c ° 400 و c ° 100 کربناته شدند. تشکیل کربن اپتایت به روش قرار دادن نمونه ها تحت نفوذ گاز ? co?_2 ، توسط آزمونهای xrd tem ,ftir مورد تائید قرار گرفت. سپس نمونه ها تحت تابش چشمه 60co ?-ray قرارگرفتند و شدت سیگنال epr آنها در دزهای 2, 5, 10, 20, 50و 80 kgy اندازه گرفت...

در این طرح ابتدا نمونه‌هایی از سبزیجات و ادویه خشک انتخاب و پس از توزین دقیق، به جهت اهمیت جرم در پاسخ دستگاه EPR، تحت تابش باریکه الکترونهای MeV 10 با دُز جذبی معادل kGy10 پرتودهی شد. پس از کالیبره کردن دستگاه، پارامترهای بهینه، ویژه ماده مورد بررسی تنظیم شدند. سپس نمونه‌ها در لولة مخصوص دستگاه قرار داده شده و طیف‌های EPR نمونه‌ها تهیه شدند و مورد مقایسه قرار گرفتند. در مرحله نهایی، به منظور بر...

X-band rapid-scan EPR was implemented on a commercially available Bruker ELEXSYS E580 spectrometer. Room temperature rapid-scan and continuous-wave EPR spectra were recorded for amorphous silicon powder samples. By comparing the resulting signal intensities the feasibility of performing quantitative rapid-scan EPR is demonstrated. For different hydrogenated amorphous silicon samples, rapid-scan...

Rock powder of dolomite samples from the Renison mine area of Tasmania, Australia were analyzed by electron paramagnentic resonance spectroscopy (EPR), Atomic Absorption and Mass Spectrometer to identify alteration related to mineralisation. The least-altered dolomite samples, which are not effected by circulation of diagenetic and hydrothermal fluids are characterised by low Mn and Fe and ...

Heterogeneous textures due to phase separation in molten polypropylene (PP)/ ethylene-propylene-rubber (EPR) blends were investigated in relation to their dynamic viscoelastic properties. As characteristic to heterogeneous liquids, slow relaxation mechanisms due to the existence of such phases were found for dynamic moduli of PP/EPR blends. These moduli were analyzed by using the linear viscoel...

The coagulation protease factor Xa induces cellular responses implicated in cardiovascular and inflammatory disease. Effector-cell protease receptor 1 (EPR-1) is a functionally characterized receptor of factor Xa, and the EPR-1 complementary DNA (cDNA) was published. Remarkably, the cDNA encoding an inhibitor of apoptosis, survivin, is reportedly identical to that of EPR-1 except for a few nucl...

BACKGROUND Induction of profound hypothermia for emergency preservation and resuscitation (EPR) of trauma victims who experience exsanguination cardiac arrest may allow survival from otherwise-lethal injuries. Previously, we achieved intact survival of dogs from 2 hours of EPR after rapid hemorrhage. We tested the hypothesis that EPR would achieve good outcome if prolonged hemorrhage preceded c...

Keywords: Self-learning Finite element Evolutionary computation Material modelling EPR a b s t r a c t In this paper an EPR-based self-learning method is presented for modelling the constitutive behaviour of materials using evolutionary polynomial regression (EPR). The proposed approach takes advantage of the rich stress–strain data buried in non-homogenous structural tests. The load–deformatio...
