Query: Disclination Dipoles as the Basic Structural Elements of Dielectric
  Glasses   We show that the experimentally observed behavior of thermal conductivity of
dielectric glasses over a wide temperature range can be explained by a
combination of two scattering processes. The first one comes from the phonon
scattering due to biaxial dipoles of wedge disclinations while the second one
is the Rayleigh type scattering. The results obtained support the cluster
picture suggested earlier for glassy materials.
