Chromophores in which vinylene units and either pyrrole or dialkoxythiophene groups form the bridge between two diarylaminophenyl groups exhibit two-photon cross-sections of 1000-5000 GM at 600-650 nm.

This paper describes the LEMUR GuitarBot, a robotic musical instrument composed of four independent MIDI controllable single-stringed movable bridge units. Design methodology, development and fabrication process, control specification and results are discussed.

Padma Multipurpose Bridge is situated on a section of the river where soil condition highly heterogeneous and intermixed with different layers, for which pile design was critical part. This paper describes properties ground profiling Bridge. Different types field laboratory tests were carried out to obtain accurate parameters profiles along whole alignment bridge. Standard Penetration Tests, Co...

The physical and mechanical properties of the reservoir bank slope deteriorate under fluctuation water level, causing debonding slippage, which can produce different degrees damage to bridge foundation, piers, superstructure, a condition that is difficult treat. In this paper, for Yangtze River Bridge instability problem in Three Gorges area, numerical model was established using finite element...

Martian terrains are represented as a series of drainage basins, regardless of the historical presence or absence of actual fluid flow. A statistical analysis of each drainage network, computationally extracted from an underlying topography based on the MOLA data, yields a network descriptor, a compact, numerical characterization of a network. These descriptors are used to compare different mar...

further choice, the bridge with lowest locants will remain uncombined. (b) The expanded base cycle may have as ring units only monocyclic rings, or where they have trivial names allowed by Organic Rules A-21.3, A-23.1, B-2, or D-Table IV in footnote 1, polycyclic rings are permitted. (c) When a bridge is combined with another part of the structure, the ring with the least number of atoms will b...

The sub-Himalayan thrust belt is an active thrust wedge which progresses southward over the northdipping Indian plate. The north–south compression resulted in severe deformation of sedimentary rocks in this belt. Distinct thrust geometries and topography have evolved under the interaction between tectonic and erosional environments. To better understand the relationship between tectonics and to...
