AC loss measurements have been made, by an electical method, on superconducting niobium samples in the form of tubes and foils. The measured losses can depend strongly on the magnetic history of the samples and characteristic flux motion waveforms are observed when losses are enhanced by the presenc
## Abstract Effects of the deletion of Ca^++^, Mg^++^, or Ca^++^ and Mg^++^ on the leakage of primary amines, Ca^++^, and Mg^++^ from gills of __Mytilus californianus__ were studied. In the absence of Ca^++^ the gills leak primary amines and Ca^++^ for about 30 minutes, after which the primary amin
