"] In order for an advertising message to be perceived, the brain of the television viewer must be available. Our broadcasts are aimed at making that brain available: i . e. by distracting it, by relaxing it and preparing it between two messages. What we sell to Coca-Cola is time with this available human brain. " Sourcing The third filter concerns the mass medias' need for a continuous flow of information to fill their demand for daily news. In an industrialized economy where consumers demand information on numerous global events unfolding simultaneously, they argue that this task can only be filled by major business and government sectors that have the necessary material resources. Motorcycle Model Kit This includes mainly The Pentagon and other governmental bodies. Chomsky and Herman then argue that a "symbiotic relationship" arises between the media and parts of government which is sustained by economic necessity and reciprocity of interest. "

" W and Z bosons, which mediate the weak nuclear force Eight species of gluons, which mediate the strong nuclear force. Six of these gluons are labelled as pairs of "colors" and "anti-colors" (for example, a gluon can carry "red" and "anti-green". ) The other two species are a more complex mix of colors and anti-colors. The Higgs bosons, which induce spontaneous symmetry breaking of the gauge groups and are responsible for the existence of inertial mass. It turns out that the gauge transformations of the gauge bosons can be exactly described using a unitary group called a "gauge group". The gauge group of the strong interaction is SU(3), and the gauge group of the electroweak interaction is SU(2)×U(1). Therefore, the Standard Model is often referred to as SU(3)×SU(2)×U(1). Gundam Seed Model Kit The Higgs boson is the only boson in the theory which is not a gauge boson; it has a special status in the theory, and has been the subject of some controversy. Gravitons, the bosons believed to mediate the gravitational interaction, are not accounted for in the Standard Model. "
