The Beta-Ray Disintegration

Double Beta-Disintegration

N a table showing the existing atomic nuclei it is observed that many groups of isobars occur, the term isobar referring to nuclei of the same atomic weight but different atomic number. It is unreasonable to assume that all isobars have exactly the same energy; one of them therefore will have the lowest energy, the others are unstable. The question arises why the unstable nuclei are in reality ...

Disintegration of the scrophulariaceae.

A molecular systematic study of Scrophulariaceae sensu lato using DNA sequences of three plastid genes (rbcL, ndhF, and rps2) revealed at least five distinct monophyletic groups. Thirty-nine genera representing 24 tribes of the Scrophulariaceae s.l. (sensu lato) were analyzed along with representatives of 15 other families of Lamiales. The Scrophulariaceae s.s. (sensu stricto) include part or a...

E3d was )ess thermostable than E3c; E3d and E3c lost half of their original activities upon incubations for 30 min at 790C and 900C, respective]y. Heat treatment of E3d raised the fluorescence ;ntensities of Trp residue, intrinsic FAD, and extrinsic 8-anilinonaphthalene-1-sulfonate. E3d lost FAD, and inactive E3d polypeptides were aggregated. The sulfonate bound to the aggregate became notably ...
