For the D = 5 Majorana neutrino mass operator to have a see-saw ultraviolet completion that is viable up to the Planck scale, the see-saw scale is bounded above due to triviality limits on the see-saw couplings. For supersymmetric see-saw models, with realistic neutrino mass textures, we compare constraints on the see-saw scale from triviality bounds, with those arising from experimental limits...

Recently, the use of microorganisms for conversion of plant biomass into many commercially valuable products has been studied. In this study, some soil samples, composting plant materials, and composted manure from different parts of Markazy province were collected to isolate and identify aerobic bacteria, which have been capable of utilizing lignin preparations as a sole source of carbon. Bact...

شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به دست آم...
The impact of ambient humidity on a surface acoustic wave (SAW) propagation in the structure consisting of hematoporphyrin (Hp) film deposited on a piezoelectric lithium niobate substrate has been studied. The SAW transmission dependencies on frequency were measured using an RF network analyzer, and the variation in the SAW velocity was measured using SAW delay-line oscillator technique. The in...
Metal surface flaws on can be detected using the frequency transmission characteristics of surface acoustic waves (SAW). In addition, noncontact, remote detection can be made possible by using laser ultrasound. So far, broadband SAW generated by a single generation laser has been used for surface flaw detection[1]. Results have shown that the SAW transmitted across a slit of depth 0.5 mm showed...

مسکن یکی از مقوله های مهمی است که بشر همواره با آن دست به گریبان بوده و برای دگرگونی و یافتن پاسخی مناسب و معقول برای آن در تلاش بوده است؛ بنابراین، مسکن یک نیاز است، اما فراتر از نیاز آنچه که ایده آل آدمی است، دسترسی به مسکنی مناسب است؛ از این رو، در مقالۀ حاضر به بررسی کیفیت مسکن مناسب در محلات شهری به صورت موردی در محلات سکونتگاهی شهر بیجار می پردازیم. روشبررسیاینپژوهش،مبتنیبررویکردتوصیفی-تح...
