An innovative one-step synthesis towards β-aryl-β,β-difluorocarbamates and β-aryl-β,β-difluoroazides is presented. The described approach relies on the use of α-fluorostyrene substrates in a radical addition/fluorination reaction with N-centered radicals presence Selectfluor®. best results were obtained for azidofluorination reaction. resultant further transformed into Nitrogen-based heterocycl...

در این پایان نامه، مترهای فینسلری از انحنای s ثابت را مطالعه می کنیم. ابتدا مترهای راندرزی با انحنای s غیرصفر(ثابت) که انحنای h صفر دارند را بررسی خواهیم کرد، که مثال نقصی برای قضیه ای در[24] می باشند. سپس با استفاده ساخته های لی و شن، نشان می دهیم (α ، β)-مترهایی با انحنای s ثابت دلخواه در هر بعد وجود داشته و غیرراندرزی می باشند.

The use of mono-amine oxidase inhibitors (MAOI) entails the risk of hypertensive crises with various foodstuffs and other drugs. On the other hand, the tricycic antidepressants have a slow onset of action, and this may be a serious disadvantage in a condition like acute depression where there is always a danger of suicide. The use of an MAOI can therefore be justified if it is shown to be more ...

The outer hair cell (OHC) is a hydrostat with a low hydraulic conductivity of Pf=3x10(-4) cm/s across the plasma membrane (PM) and subsurface cisterna that make up the OHC's lateral wall. The SSC is structurally and functionally a transport barrier in normal cells that is known to be disrupted by salicylate. The effect of sodium salicylate on Pf is determined from osmotic experiments in which i...

Acute myeloid leukemia (AML) cases with 11q23 abnormalities involving the MLL gene comprise one category of recurring genetic abnormalities in the WHO classification. In an unselected series of 1897 AML cases, 54 patients with an 11q23/MLL rearrangement were identified, resulting in an incidence of 2.8%. The incidence of AML with MLL rearrangement was significantly higher in therapy-related AML...

A d-dimensional framework is a straight line realization of a graph G in Rd . We shall only consider generic frameworks, in which the co-ordinates of all the vertices of G are algebraically independent. Two frameworks for G are equivalent if corresponding edges in the two frameworks have the same length. A framework is a unique realization of G in Rd if every equivalent framework can be obtaine...
