چکیده: فاز هندسی یک فاکتور فاز انتگرال ناپذیر است که از ترابرد بی دررو یک سیستم حول یک مسیر بسته در فضای پارامترش بوجود می آید. اخیراً توجه زیادی به اثر فاز هندسی در سیستم های اسپینی معطوف شده است که در این رساله به بررسی می پردازیم. با استفاده از یک رهیافت جدید که برپایه مکانیک کوانتوم برهمکنش اسپین-مدار استوار است، به مطالعه ترابرد قطبش فوتون های در محیطهای ناهمگن می پردازیم[1]. این رهیافت ق...

BACKGROUND The study on phytochemical difference between red and black goji berry is limited. METHODS Antioxidant activities and phenolic profiles in terms of total phenol content, total flavonoid contents, condensed tannin content, monomeric anthocyanin content, and total carotenoid content of red goji berry (Lycium barbarum) and black goji berry (L. ruthenicum) were compared using colorimet...

Overwhelming evidence suggests that edible small and soft-fleshed berry fruits may have beneficial effects against several types of human cancers. The anticancer potential of berries has been related, at least in part, to a multitude of bioactive phytochemicals that these colorful fruits contain, including polyphenols (flavonoids, proanthocyanidins, ellagitannins, gallotannins, phenolic acids),...

We analyze 2-dimensional Ginzburg-Landau vortices at critical coupling, and establish asymptotic formulas for the tangent vectors of the vortex moduli space using theorems of Taubes and Bradlow. We then compute the corresponding Berry curvature and holonomy in the large area limit.

V. vinifera L. 'Barbera', 'Croatina', 'Malvasia di Candia aromatica', growing in the Piacenza viticultural area (North-West Italy) at four elevations (150, 240, 320, 420 m a.s.l.), were tested at harvest for grape stilbene (trans-resveratrol, trans-piceid, cis-piceid) synthesis over three years (2000-2002). Meteorological data were recorded, as well as vine production and fruit quality paramete...
