Schlaefer, K., et al. (2007) found that exposure to radio frequency and microwave electromagnetic fields can contribute to an increase the incidence of brain tumors. The same kind of radio frequency and microwave electromagnetic fields are produced by cell phone phones. If Radio frequency and microwave electromagnetic fields are both produced by cell phones than this could be an issue to anyone who uses a cell phone. If exposure to these radio frequencies and or microwave electromagnetic waves increases

5, 24 Nov 2014, Webster University A major communication issue on September 11th 2001 at the World Trade Center was the ineffective repeater system. A radio repeater system helps radio receivers such as a hand held radio and radio transmitters that would be located in a commutation center, they will receive a weak signal from a hand held radio and then retransmit it to a higher level, which allows the signal move a longer distance. One of the fire chiefs recommended after the south tower was hit

with, global giants such as Apple, Best Buy, and Amazon. RadioShack began as a store that sold a large variety of radio equipment, accessories, spare parts, testing gear, and technician tools. With the constant change in technology and demand for it, they went away from their roots and something went terribly wrong. They decided to drop the idea of being an “old obsolete radio store” and attempted to shift into the 21st century, yet if you ask a millennial what they buy at RadioShack, the most

These behaviors are taught by parents to their children, teachers to their students, media to their viewers, etc. Culture is all around us at every point
