The Justice Department and the F.B.I. have begun a criminal investigation to determine whether John M. Deutch, a former director of the C.I.A., mishandled classified material by placing it on unsecured computers in his home, government officials said today.
The Justice Department, in a reversal of an earlier decision, has begun a criminal investigation with the F.B.I. to determine whether John M. Deutch mishandled classified material by placing it on unsecure computers in his home, officials said.
In 1857 Lord Kelvin was the first to observe that it was possible to alter the electric resistance of a conducting material by placing it in an external magnetic field.
Although the Justice Department and F.B.I. investigation to determine if John M. Deutch, the former C.I.A. director, mishandled classified material by placing it on unsecured computers in his home may be in the right direction, those agencies may be missing some aspects of security (front page, May 6).
Our objective in this study was to compare the bone-regenerating ability of DDM as bone graft material by placing it in cranial defects of rabbits using different sizes and densities of this material.
Fabrication of PEDOT PSS/PDMS Actuators: Silicon wafers (400 μm thick, p-type, boron doped, <100>, Si-Mat Silicon Materials) were silanized by placing them in a desiccator for 30 min along with a vial that contained a few drops of silanizing agent (chlorotrimethylsilane, Sigma Aldrich).
This material is produced by placing the scan vectors for the laser additive manufacturing process in a defined pattern.
Eluates of each material were prepared by placing each disk into a sterile glass vial with 25 mL of Dulbecco's Modified Eagle's medium (Sigma-Aldrich), supplemented with penicillin-streptomycin and fetal bovine serum (Sigma-Aldrich).
For the case of small material deformations, this instability is typically avoided by placing the material points away from cell boundaries.
