At periods greater than 1000 seconds, Earth's seismic free oscillations have anomalously large amplitude when referenced to the Harvard Centroid Moment Tensor fault mechanism, which is estimated from 300- to 500-second surface waves. By using more realistic rupture models on a steeper fault derived from seismic body and surface waves, we approximated free(More)
We have studied in detail the procedure for the direct determination of serum thyroxine based on the liberation of (125)I T-4 from a tagged euthyroid serum reagent, the thyroxine being liberated by alcohol denaturation from 0.5 ml. of patient serum.We have established that there is proceeding simultaneously a second mechanism of T-4 liberation which is in(More)
