This study provides an analysis of multistory reinforced concrete residential buildings to earthquakes considering local uplift foundation, soil behaviour, site category and seismicity area as suggested by the Moroccan seismic regulation. The superstructure was modeled a flexible column with lumped mass placed at top under hypothesis large rotations or small rotations. governing equations coupl...

The influence of applied electric fields on the pretransitional optical activity Ii) in the chiral nematic 4-cyano-4-(2-methyl)butylphenyl (CB15) was investigated. A rotating analyzer system was used to measure the optical activity and fields

Solutions of the proteins represent in one sense simple systems, rather than complex ones. The properties of proteins in solutions which depend more or less upon changes in electric charge can be investigated directly through the study of the electric mobility of the protein ions 1 and indirectly by means of titration curves with acids, optical rotation, viscosity, etc. If one makes certain ass...

Measurement of optical rotation in RbTiOAsO4 (RTA) with the tilter method resulted in an optical rotation of r12 1⁄4 þ17ð3Þ /mm at a wavelength of 670 nm, when a (100) sample was tilted about [001]. A tilt about [010] showed no rotation, as expected from the directional dependence of optical rotation calculated from the tensor in point group mm2. The absolute Miller-indices of the samples were ...

The using possibility of the vortex light beam with topological charges 2 and 5 for the rotation of the micromechanical element (microturbine) was considered. The results of the full-scale experiment on the optical rotation of the special form microturbine were presented. We evaluated the force moment, acting the microturbine.

Three-dimensional photonic crystals (3D PhCs) are a fascinating platform for manipulating photons and controlling their interactions with matter. One widely investigated structure is the layer-by-layer woodpile structure, which possesses a complete photonic bandgap. On the other hand, other types of 3D PhC structures also offer various possibilities for controlling light by utilizing the three ...

We propose to implement a \multi-argus" facility at CFHT. The main scientiic driver of this project is the study of the evolution of the Tully-Fisher relation at intermediate redshift, thanks to the use of the optical rotation curves of spiral galaxies. The multiplex gain makes this project quite attractive, even on a 4m-size telescope such as CFHT. From the instrumental side, the idea is to mo...
