The perovskite compounds Ba0·6K0·4BiO3 and BaPb1−x Bi x O3 (x=0·9, 0·5, 0·25) have been investigated by high resolution electron microscopy and selected area electron diffraction. Several superlattices produced byin situ electron beam reductio

A solid solution range exists between the systems YBa 2 Cu 3 O 7− δ and (Pb,Cu)Sr 2 (Ca,Y)Cu 2 O 7− δ has been successfully synthesized. The microstructures across the solid solution are complicated by the presence of an incommensurate or comme

Although the location, planning and operation of building stone quarries is similar in many respects to other industrial minerals, the scale of the operation and the methods used for stone extraction result in significant differences. Restoration and

This paper describes the use of precision GPS time transfer to form an ensemble of hydrogen maser clocks. The performance of this ensemble, including the GPS time transfer system, was measured relative to a stable linear ion trap standard. Very high-

The identification and cloning of the mitochondrial autoantigens in primary biliary cirrhosis (PBC) have provided new clues in disease pathogenesis. The two major autoantigens are the E2 subunits of pyruvate dehydrogenase and branched-chain ketoacid

The Schelzer resolution is defined as the highest spatial frequency which is transferred into the image with the same phase as all lower frequencies. The resolution of the information limit is, however, determined by the information from the specimen
