SOME UNUSUAL REACTIONS OF 3-PHENYLAMINOISOXAZOL-5 (2H)- ONES
3-Phenylaminoisoxazol-5(2H)-ones,s ubstituted on nitrogen with an isoquinoline or quinazoline group, react with tertiary amine bases to give imidazo annelated compounds. When the N-substituent is a nitropyridine, 2-aminoindole derivatives are formed instead. Evidence is presented that the reactions proceed by initial addition of the tertiary arnine to C-4
متن کاملSome Unusual Joint Lesions
a matter of considerable difficulty and treatment protracted and laborious. The disability and impairment of .function may be out of all proportion to the pathological lesion. Moreover, it is often necessary to supplement any operative procedure by a prolonged course of graduated remedial exercises or of physio-therapy. The management of such cases, therefore, requires considerable experience a...
متن کاملSome Aspects of Classical and Quantum Phases
We study classical and quantum phases in the adiabatic BornOppenheimer context. These include a classical astronomical case, the general dual description of the phases, a new “Paradox” connected to scattering Berry phase and its resolution and various elaboration of topological/geometrical/non-abelian phases.
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولUnusual ordered phases of highly frustrated magnets: a review.
We review ground states and excitations of a quantum antiferromagnet on triangular and other frustrated lattices. We pay special attention to the combined effects of magnetic field h, spatial anisotropy R and spin magnitude S. The focus of the review is on the novel collinear spin density wave and spin nematic states, which are characterized by fully gapped transverse spin excitations with S(z)...
