Possible Observation of Photon Speed Energy Dependence

Current constraints on photon velocity variability are summarized and displayed in terms of an energy dependent vacuum refraction index. It is shown that the energy-momentum balance of high energy Compton scattering is very sensitive to the outgoing photon speed. A missing energy observation in HERA Compton polarimeter data indicates that photons with 12.7 GeV energy are moving faster than light by 5.1(1.4)mm/s. An asymmetry spectrum measured by the SLC longitudinal polarimeter implies however an effect which is 42 times smaller, although the interpretation of the data is less clear here.Comment: 13 pages, 3 figure

Characteristics of proteins from normal, high lysine, and high tannin sorghums

The purpose of this paper was to study the characterirtics of proteins from normal, high lysine, and high tannin Sorghum bicolor (I,.) Moench. Endosperm preparations were otltained from four inbred lines of sorghum representing a normal, low tannin variety (P-721-N), its mutagenically derived high lysine counterpart (P-721-O), an inbred Ethiopian variety high in lysine (IS-11167), and a high tannin line (IS-4225). Endosperm proteins were separated into five soluble fractions by the Landry Moureaux method
