An efficient and convenient method for synthesis of 2,6-bis (4-(dialkylamino) styryl)-4H-pyran-4-one starting from 4- (dialkylamino) benzaldehyde with 2,6-dimethyl-4H-pyran-4-onein the presence of MeONa as the base was described. Additionally, preparation of novel compounds with bis-DCM-type skeleton for application in organic light-emitting diodes was developed via reactio...

3,3-Dichloro-N-p-methoxyphenyl-4-(2-phenylstryl)-2-azetidinone (C22H15Cl2NO2) was studied by X-Ray analysis, which indicated a monoclinic space group, P2(1)/c, with a = 9.619(5), b = 13.879(4), c = 14.161(5)A, beta = 100.16(3)degrees, V = 1860.8(13)A3, Z = 4, Dc = 1.414 g cm(-3), micro(Mo Kalpha) = 0.366 mm(-1) and F000 = 816. The structure was solved by direct methods and refined to R = 0.041 ...

Foreword The Slovak National Committee for IUGG is pleased to present the second Slovak National Report to IUGG which should provide a concise summary of the geophysical and geodaetic research, and results accomplished in the period of 1999 – 2002 in the Slovak Republic. The Report consists of partial reports to five associations – IAG, IAGA, IAHS, IAMAS and IASPEI. The reports to associations ...

For many years the urban renewal approach of Rotterdam, executed during the period 19751993, served as an example on the national and international level. With this approach a process of revitalization was initiated, which meant that the urban fabric and building supply had to adapt to changing conditions and accommodate new demands. Due to large financial and social investments in Rotterdam, a...

BubR1 is a well-defined guardian of the mitotic spindle, initiating mitotic arrest in response to the lack of tension and/or chromosome alignment across the mitotic plate. However, the role of BubR1 in combretastatin-induced cell death remains unknown. In this study, we describe the effects of combretastatin A-4 (CA-4) and a synthetic cis-restricted 3,4-diaryl-2-azetidinone (ß-lactam) analogue ...
