Flash is an electronic animation that can be watched on a computer or monitor with a microprocessor. It is rich in content and can simultaneously display images, sound and text, its data is very few, generally speaking, the amount of data of an animated video accounts for 1/ 4 to 1/ 10 of a physical video with the same size and definition. Its development brings opportunities for modern educational technology curriculum of higher normal university, making it present a more rich content and form. The relevant overviews of online virtual laboratory are first discussed in this paper, and then is its construction process. © (2014) Trans Tech Publications, Switzerland. Source

A new Eu(III) complex, Eu(III)(DBM) 3BIOQ, has been synthesized with dibenzoylmethane (DBM) as the first ligand and 2-(benzimidazol-2-yl)-8- octyloxyquinoline (BIOQ) as the second ligand. The stability of the complex was analysed by DSC-TG. The results show that the Eu(III) complex has a relatively high thermal stability with a melting point of 235 °C and a decomposition temperature (onset) of 252 °C. The fluorescence properties of the compound were also investigated. The fluorescence results reveal that the as-prepared complex shows the characteristic maximum emission spectra of Eu(III) at 611 nm (® ex = 350 nm). In addition, the photoluminescence spectrum of the complex in the solid state exhibits a single and symmetrical emission band at 611 nm, with a full width at half-maximum of 4.7 nm, showing high colour purity. This finding indicates the possibility for the development of brighter red luminescent materials. Copyright © 2011 John Wiley & Sons, Ltd. Source

The title hydrazone compound, C15H14N 2O2, was prepared by the condensation of 4-hy-droxy-benzaldehyde with 2-methyl-benzohydrazide in methanol. The dihedral angle between the two benzene rings is 42.3 (2)°. In the crystal structure, molecules are linked by inter-molecular O - H⋯O, O - H⋯N and N - H⋯O hydrogen bonds, forming a three-dimensional framework. Source

Flavonoids, also called vitamin P, are widely distributed in plants fulfilling many functions. Yeast α- glucosidase (YAGH; EC, as extensively used target protein for screening bioactive compounds from medicine plants, was selected to explore the possible mechanisms of multiple biological function of flavonoids. The results in this study indicated that flavonoids, as mixed-type inhibitors, quenched the intrinsic fluorescence of YAGH by a mixed fluorescence quenching mechanism. The interaction information between flavonoids and YAGH was analyzed using a flexible docking method (AutoDock) and showed that 3', 4' dihydroxyl groups of B ring and 3-OH of C ring played a more important role in the inhibition activity than other hydroxyl groups, because the 3', 4' dihydroxyl groups of B ring directly interacted with the active-site residues of YAGH to inhibit enzyme activity and 3-OH of C ring seemed to be necessary to maintain the proper binding orientation of flavonoid molecules, thereby making the hydroxyl groups of B ring interact with active-site residues tightly in the hydrophobic pocket of YAGH. The results supply a basis for understanding the mechanisms of multiple biological functions of flavonoids. © 2010 Bentham Science Publishers Ltd. Source
