(a) After injection of labeled leucine into the eye of goldfish, radioactive protein rapidly accumulates in the contralateral optic tectum in the layer containing the synaptic endings of the optic fibers. This material reaches the tectum 6-12 hr after the isotope injection, a fact which indicates that the rate of tran…

Thermal and x-ray diffraction measurements on compositions from the system NaxK1−xNbO3 have revealed the presence of phase boundaries at approximately 82.5, 67.5, and 52.5 mole × NaNbO3 at 25°C, in addition to one very near the NaNbO3 end member. The optimum piezoelectric properties in this system are apparently assoc…
Summary Potassium pyrophosphate (0.1 m ) removes very little Fe from crystalline Fe oxides at pH 10, but peptizes finely divided hydrous amorphous oxides and organic matter in soils. Fe and C contents of extracts from each horizon of twenty‐six British soil profiles show distinctive patterns, independent of the residu…
We describe here a metallic ferromagnetic system ${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}{\mathrm{S}}_{2}$ and ${\mathrm{Co}}_{1\ensuremath{-}x}{\mathrm{Ni}}_{x}{\mathrm{S}}_{2}$ that appears to have a single doubly degenerate band. The electrons in the band are itinerant as manifested by metallic electrical…
The rate of quenching of triplet excitons by paramagnetic impurities in anthracene crystals at room temperature is found to be magnetic-field dependent. A theory of the effect is presented.Received 17 July 1968DOI:https://doi.org/10.1103/PhysRevLett.21.609©1968 American Physical Society
Ridges forming the concentric sculpture on the shells of laboratory-grown specimens of Pecten diegensis Dall show daily periodicity. Missing growth lines account for all scatter in the data, so that the maximum, not the average, line count is most representative. The variation in spacing between growth lines can be co…
Abstract : A performance analysis of the thermochemical/thermomechanical behavior of graphite is made extending present analysis procedures to include the allotropic features of bulk graphite. The analysis comprises a complete definition of graphite sublimation, and formulates a model for mechanical erosion based on e…
