In this paper, we report on the time-dependent strain-wave-induced changes in reflection and diffraction of a gold plasmonic grating. We demonstrate efficient excitation strain waves using enhanced absorption at around surface plasmon polariton resonance. addition, observe that grating show an approximately quadratic dependence pump fluence when probed wavelength 400 nm. tentatively attribute n...
قرن هاست که از تخمیر برای حفاظت، بهبود کیفیت و یا اصلاح عطر و طعم حبوبات، میوه ها، سبزی ها، شیر و گوشت استفاده می شود. تاریخچه ترشی و شوری در ایران به زمان قوم ماد بر می گردد، در حالی که از عمر تولید صنعتی ترشی و شوری در ایران تنها70 سال می گذرد. سالاد زمستانه در واقع نوعی شوری تهیه شده از سبزی های مختلف است که در ایران و بخصوص در خراسان مصرف می شود. هدف از این پژوهش بررسی اثر سطوح مختلف شلغم ف...
We have performed a comprehensive first-principles study of the electronic and magnetic properties of two-dimensional (2D) transition-metal dichalcogenide (TMD) heterobilayers MX2/MoS2 (M = Mo, Cr, W, Fe, V; X = S, Se). For M = Mo, Cr, W; X = S, Se, all heterobilayers show semiconducting characteristics with an indirect bandgap with the exception of the WSe2/MoS2 heterobilayer which retains the...
The stress-strain response of Zr due to twinning is distinctly different from that due to slip as a function of temperature and strain rate. When the applied stress is lower than the transition stress, dislocation slip is the dominant deformation mechanism. The traditional MTS model is shown to adequately represent the constitutive behavior of Zr. Above the transition stress twinning becomes th...
رها شدن گاز so2 در اثر احتراق سوخت های فسیلی یکی از علل اصلی آلودگی زیست محیطی و بیماری های تنفسی می باشد. عمده ترین ماده گوگردی موجود در نفت خام و برش های آن به صورت دی بنزوتیوفن و مشتقات الکیله آن می باشد. در گوگردزدایی زیستی، حذف گوگرد از برش های نفتی با استفاده از باکتری ها توسط محصولات ژن هایabc dsz که اولین بار از باکتریrhodococcus erythropolis strain igts8 جدا شدند از طریق مسیرمتابولیکی ...
We combine triangulation, trilateration, and GPS observations to determine horizontal strain rates along the Cascadia subduction zone from Cape Mendocino to the Strait of Juan de Fuca. Shear-strain rates are significantly greater than zero (95% confidence) in all forearc regions (26-167 nanoradians/yr), and are not significant in the arc and backarc regions. The deformation is primarily uniaxia...
Strain and strain rate imaging have been shown to be useful for the assessment of regional myocardial function. However, some of the mechanisms of transition in myocardial contraction/relaxation remain unclear. In this study, the RF echoes from the left ventricular (LV) wall were acquired in both the longitudinal-axis view and the apical view by scanning ultrasonic beams sparsely to improve the...
Electrical field-induced strain response of electron-irradiated Poly(viny1idene fluoride trifluoroethylene) copolymer has been studied by a Mach-Zehnder type Heterodyne interferometer in the frequency range of 3 to 9 kHz. The electrostrictive constant is calculated from the strain results, which is of the same order of magnitude as those obtained at 1 Hz by a bimorph-based strain sensor, but at...
Electrical field-induced strain response of electron-irradiated poly~vinylidene fluoride-trifluoroethylene! copolymer has been studied by a Mach–Zehnder type heterodyne interferometer in the frequency range of 3–9 kHz. The electrostrictive constant is calculated from the strain results, which is of the same order of magnitude as those obtained at 1 Hz by a bimorph-based strain sensor but at muc...
