چکیده ماتریس هیلبرت روی اکثر فضاهای هاردی و برگمن عملگری کراندار القا می کند. دراین رساله با بکارگیری نتیجه ای از هالنبک و وربیتسکی بر روی تصویر ریس، این مطلب را برای هر عملگر هانکل روی فضاهای هاردی تعمیم می دهیم و نرم ماتریس هیلبرت را در فضاهای هاردی و برگمن محاسبه می کنیم. علاوه بر این درباره ی خصوصیات فضاهای هاردی و برگمن صحبت کرده وموارد زیر را با در نظر گرفتن این که h_g عملگر هانکل، h مات...
A new methodology to build discrete models of boundary-value problems is presented. The h-pcloud method is applicable to arbitrary domains and employs only a scattered set of nodes to build approximate solutions to BVPs. This new method uses radial basis functions of varying size of supports and with polynomialreproducing properties of arbitrary order. The approximating properties of the h-p cl...
Pseudomonas sp. strain AZR1 and Klebsiella sp. strain AZR2 were isolated from reconstituted instant chocolate puddings that had turned green and were found to have azoreductase activity. This activity was inducible and NADH dependent. Differences in dye reduction rates between the two strains were apparent, and substrate specificity related to dye structure was observed.
A chemoselective [3+3] cycloaddition of in situ generated azomethine ylides with quinone monoimides has been established, which efficiently led to the construction of dihydrobenzoxazine frameworks with biological relevance, with excellent chemoselectivities and high yields (up to >95 : 5 cr and 98% yield).
Self-healing Langerhans cell histiocytosis (SHLCH) is a rare self-limited variant of Langerhans cell histiocytosis that presents at birth or during the neonatal period. It was first described by Hashimoto and Pritzker in 1973. Subsequently, more than 70 cases have been reported in the literature. Regarding age of onset, SHLCH should be divided into congenital SHLCH and rare late-onset type. We ...
In the title mol-ecular salt, C(6)H(16)N(+)·NO(2) (-), the cation forms two N-H⋯O hydrogen bonds to nearby nitrite anions which link the ionic units into chains propagating along the b-axis direction.
