When deriving velocity models by forward modelling or inverting travel time arrivals from seismic refraction data, a heterogeneous but isotropic earth is usually assumed. In regions where the earth is not isotropic at the scale at which it is being sampled, the assumption of isotropy can lead to significant errors in the velocities determined for the crust and the depths calculated to reflecting boundaries...
Clinical studies have shown that ionic zinc (Zn 2+ ) dissolved in the mouth shortened manifestations of the common cold significantly, by an unknown mechanism. The observed immediate effect on symptoms is consonant with osmotic transport of Zn 2+ , placing a temporary chemical clamp on critical nerves. It is proposed that transient elevation of Zn 2+ concentration in and around...
