To understand the role of the conjugate bridge in modifying the properties of organic dye sensitizers in solar cells, the computations of the geometries and electronic structures for 10 kinds of tetrahydroquinoline dyes were performed using density functional theory (DFT), and the electronic absorption and fluorescence properties were investigated via time dependent DFT. The population analysis...

OBJECTIVES This is a prospective study of the clinical efficacy of the V.A.C. Granufoam Bridge Dressing for the treatment of diabetic foot ulcers. MATERIALS AND METHODS Five consecutive patients with diabetic foot ulcers were treated with V.A.C. Granufoam Bridge Dressings and studied over a period of 22-48 days. The indications for treatment included diabetic patients with open ray amputation...

A program for engineering wood bridges is described. The program performs the analysis, design, and/or rating of wood bridge superstructures in accordance with the 15th Edition of the AASHTO Specification or the AASHTO-LRFD Specification. Bridges may be analyzed for design review and/or rating. In review/rating mode, the superstructure is analyzed and checked against all applicable specificatio...

The coil-bridge transition in a self-avoiding lattice chain with one end fixed at height H above the attractive planar surface is investigated by theory and Monte Carlo simulation. We focus on the details of the first-order phase transition between the coil state at large height H ⩾ Htr and a bridge state at H ⩽ Htr, where Htr corresponds to the coil-bridge transition point. The equilibrium pro...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

To identify critical sediment sources in large catchments, using easily available terrain information at a regionalscale, a methodology was developed to obtain a qualitative assessment necessary for environmental management.Fargas et al method was employed in the research. The study was carried out in one of the sub-basins of Hableh Roodbasin called Dehnamak in the arid and semiarid climate of ...

The asymmetric unit of the title compound, C(19)H(22)N(2), contains one half-mol-ecule. The 1,2,3,4-tetra-hydro-quinoline units are linked by a methyl-ene bridge, which lies on a twofold rotation axis. The non-aromatic ring adopts a flattened-boat conformation. The dihedral angle between the two symmetry-related benzene rings is 64.03 (7)°.
