Within the framework of equilibrium statistical mechanics the free energy of a phase gives a measure of its associated probabilistic weight. In order to determine phase boundaries one must then determine the conditions under which the free energy difference (FED) between two phases is zero. The underlying complexity usually rules out any analytical approaches to the problem, and one must theref...
متن کاملNa - O Anticorrelation And HB I . The Na - O anticorrelation in NGC 2808 ⋆
We derived atmospheric parameters and elemental abundances of Fe, O and Na for about 120 red giant stars in the Galactic globular cluster NGC 2808. Our results are based on the analysis of medium-high resolution (R=22000-24000) GIRAFFE spectra acquired with the FLAMES spectrograph at VLT-UT2 as a part of a project aimed at studying the Na-O anticorrelation as a function of physical parameters i...
متن کاملمقایسه ابعاد پریتسیوم دو گونه قارچ عامل بیماری مرگ نارون (Ophiostoma ulmi و O. novo-ulmi)
بیماری مرگ نارون یکی از مخرب‌ترین بیماری‌های پژمردگی آوندی در دنیا می‌باشد. دو قارچ Ophiostoma ulmi و O. novo-ulmi عوامل اصلی بیماری مرگ نارون در یک قرن گذشته بوده‌اند. این دو گونه امروزه براساس یک سری مشخصات مورفولوژیکی، فیزیولوژیکی و مولکولی از هم قابل تفکیک هستند. در این میان ابعاد پریتسیوم جدایه‌های دو گونه مزبور برروی محیط کشت عصاره مالت- آگار از مهم‌ترین عوامل تفکیک این دو گونه محسوب می‌ش...

YASAMIN MOSTOFI Q. Why are cooperative sensor networks interesting as a research topic? What are some of the benefits and challenges of this technology? Yasamin: The unprecedented growth of sensing, communication, and computation in the past few years has the potential for fundamentally changing the way we interact with our environment. The vision of a multi-agent robotic network cooperatively ...
