" At high energies (far beyond the reach of current experiments), the symmetry of the unifying group is preserved; at low energies, it reduces to SU(3)×SU(2)×U(1) by a process known as spontaneous symmetry breaking. The first theory of this kind was proposed in 1974 by Georgi and Glashow, using SU(5) as the unifying group . A distinguishing characteristic of these GUTs is that, unlike the Standard model, they predict the existence of proton decay. In 1999, the Super-Kamiokande neutrino observatory reported that it had not detected proton decay, establishing a lower limit on the proton half-life of 6. 7× 1032 years. This and other experiments have falsified numerous GUTs, including SU(5). Another effort to address the first defect has been to develop Preon models which attempt to set forth a substructure of more fundamental particles than those set forth in the Standard Model. Latin Hip Hop Model In addition, there are cosmological reasons why the standard model is believed to be incomplete. Within it, matter and antimatter are symmetric. "

" During the year 2005 in the USA, the Government Accountability Office (GAO) criticised the George W. Bush administration for the preparation and distribution of videos which falsely give the impression of being interviews made independently of the administration. The New York Times claimed that more than 20 federal agencies, including the State Department and the Defense Department, now create fake news clips. The Bush administration spent $254 million in its first four years on contracts with public relations firms, more than double the amount spent by the Clinton administration. [1] [2] Flak The term "flak" has been used to describe what Chomsky and Herman see as targeted efforts to discredit organizations or individuals who disagree with or cast doubt on the prevailing assumptions which Chomsky and Herman view as favorable to established power (e. g. , "The Establishment"). Latin Top Model Unlike the first three "filtering" mechanisms — which are derived from analysis of market mechanisms — flak is characterized by concerted and intentional efforts to manage public information. Flak from the powerful can be either direct or indirect. "
