objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

The purpose of this paper is to provide scientific basis for the stability evaluation overburden rock repeated mining goaf under expressway. objectives present study are reveal development fractures and identify fractal characteristics fractures. results show that (1) separation fracture vertical fissure developed in mining; (2) after lower coal seam, obviously retained general. number on both ...

We analyze the thermal conductivity of ions (equivalent to the conductivity of phonons in crystalline matter) in a neutron star envelope. We calculate the ion/phonon thermal conductivity in a crystal of atomic nuclei using variational formalism and performing momentum-space integration by Monte Carlo method. We take into account phonon-phonon and phonon-electron scattering mechanisms and show t...
