Takayasu’s arteritis is a chronic inflammatory and stenotic disease of medium and large sized arteries. We report clinical, laboratory and imaging findings of a 23 year old girl who presented with history of sudden onset of left hemiparesis, absent

Rugged coatings, originally developed for thermographic purposes in the 8-14 (mu) IR band, have been found to be useful as stray-light suppressants in optical instrumentation. Data on the hemispherical diffuse and goniophotometric reflectances of one

The MLS method for measuring surface roughness (rms roughness RQ in the range 1 - 200 microns) is reviewed for the usual case of a nominally planar target surface. Application is then made to surfaces with cylindrical curvature, as would be found typ

Germanium-cordierites are derived from the Mg-cordierite ceramic by partially replacing silica in the hexagonal structure with germania. A family of fully crystalline ceramics is thus obtained whose stoichiometry is given as: 2MgO • 2Al2O3 • (5-X
