There is a tendency to equip filtering respiratory protective devices with a blower system to lower the breathing resistance. Because there is a continuous flow of air through the filter, the possi...

The specific heat ${\mathit{C}}_{\mathit{v}}$ of ${\mathrm{Pr}}^{3+}$- and ${\mathrm{Eu}}^{3+}$-doped silicate glasses has been determined between 0.1 and 10 K. Below about 5 K, ${\mathit{C}}_{\mathit{v}}$\ensuremath{\propto}${\mathit{T}}^{1+\ensurem

The interpretation of measurements of the land-atmosphere exchange of NO and NO 2 is complicated by the interference of chemical reactions in air. In the absence of measurements to test correction procedures a one-dimensional surface layer model was

Optical dephasing and specific heat were measured on each of tworare-earth-doped silicate glasses between 0.4 and 12K. The homogeneous line width and the contribution of the two-level-systems(TLS) to the specific heat follow thwe same temperature dep

Specific heat data below 1 K of Bi2Sr2CaCu2O8 and YBa2Cu3O7 are analyzed. For YBa2Cu3O7 the nuclear specific heat, CN, amounts to 38T−2 μJ/mol K. CN for Bi2Sr2CaCu2O8 exceeds that of YBa2Cu3O7 by a factor of 15. The nuclear quadrupolar specific he
