Abstract We provide a complete characterization of the metric Killing bundles (or bundles) Kerr geometry. Metric can be generally defined for axially symmetric spacetimes with horizons and, case geometries, are sets black holes ( BHs ) or and naked singularities NSs geometries. Each bundle has an equal limiting photon (orbital) frequency, which defines coincides frequency horizon in extended pl...
We study first BGG operators and their solutions on homogeneous conformal geometries. focus Killing tensors, Killing--Yano forms twistor spinors in particular. develop an invariant calculus that allows us to find explicitly using only algebraic computations. also discuss applications holonomy reductions conserved quantities of circles. demonstrate our result examples geometries coming mostly fr...
The People Vs Tech: How the Internet is Killing Democracy (and How We Save It) by Jamie Bartlett. New York: Dutton, 2018. 256 pp., £8.99 (p/b), ISBN 978-1785039065.
The purpose of this study was to determine whether immunization with purified outer membrane vesicles (OMV) from Treponema pallidum (T.p. ) could elicit Abs capable of killing this organism. It is well established that the immunization of rabbits or mice with killed T.p. or with recombinant T.p. Ags has failed to generate serum killing activity comparable with that of infection-derived immunity...
