PURPOSE To present and discuss numerical calculations of the specific absorption rate (SAR) and temperature in comparison to regulatory limits. While it is possible to monitor whole-body or whole-head average SAR and/or core body temperature during MRI in practice, this is not generally true for local SAR values or local temperatures throughout the body. While methods of calculation for SAR and...

Systemic acquired resistance (SAR) is a potent innate immunity system in plants and has been used in rice fields. Development of SAR, involving priming, is achieved by activation of salicylic acid (SA)-mediated pathway. To determine whether heat shock (HS) treatment can induce SAR, we analyzed the effects of HS on Arabidopsis. HS treatment induced disease resistance, expression of SAR marker ge...

غلاف سوخت‌های هسته‌ای یکی از مهم‌ترین اجزا رآکتور محسوب می‌شود. این غلاف‌ها آلیاژ زیرکونیم ساخته می‌شوند؛ اما خواص ترمومکانیکی چندان مناسبی ندارند؛ لذا در پژوهش سعی شده با تغییر مواد به‌کاررفته NuScale به یک نوترونیکی و مناسب دست پیدا شود. قلب موجب ضریب تکثیر مؤثر طول بازه سوخت‌گذاری می‌گردد. شبیه‌سازی که M5 بهره می‌برد به‌عنوان معیار هم‌­چنین همراه سه نوع دیگر آلیاژهای رایج دو آن FeCrAl است، د...

AIMS Sarcalumenin (SAR) is a Ca(2+)-binding protein expressed in the longitudinal sarcoplasmic reticulum (SR) of striated muscle cells. Although its Ca(2+)-binding property is similar to that of calsequestrin, its role in the regulation of Ca(2+) cycling remains unclear. METHODS AND RESULTS To investigate whether SAR plays an important role in maintaining cardiac function under pressure overl...

To clarify the role of ethylene in systemic acquired resistance (SAR), we conducted experiments using Arabidopsis ethylene response mutants. Plants that are nonresponsive to ethylene (i.e., [theta]tr1 and [theta]in2) showed normal sensitivity to the SAR-inducing chemicals salicylic acid (SA) and 2,6-dichloroisonicotinic acid with respect to SAR gene induction and pathogen resistance. This indic...

Target recognition systems using Synthetic Aperture Radar (SAR) data require well-focused target imagery to achieve high probability of correct classification. Techniques for improving the image quality of complex SAR imagery are investigated. The application of phase gradient re-focusing of target imagery having crossrange smearing is shown to significantly improve the target recognition perfo...
