Karl Ferdinand Braun was a German Electrical Engineer, inventor and Nobel laureate in physics. Braun contributed to the development of radio and television technology: he shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy". Braun was born in Fulda and educated at the University of Marburg and received a Ph. D. from the University of Berlin in 1872. In 1874, he discovered, he became director of the Physical Institute and professor of physics at the University of Strassburg in 1895. In 1897, he built the first cathode-ray cathode ray tube oscilloscope. CRT became the cornerstone in developing electronic television. In early 21st century, the flat screen technologies began to replace the CRT technology on both television sets and computer monitors; the CRT is still called the "Braun tube" in German-speaking countries and other countries such as Korea and Japan. During the development of radio, he worked on wireless telegraphy.
In 1897, Braun joined the line of wireless pioneers. His major contributions were the introduction of a closed tuned circuit in the generating part of the transmitter, its separation from the radiating part by means of inductive coupling, on the usage of crystals for receiving purposes. Around 1898, he invented a crystal detector. Wireless telegraphy claimed Dr. Braun's full attention in 1898, for many years after that he applied himself exclusively to the task of solving its problems. Dr. Braun had written extensively on wireless subjects and was well known through his many contributions to the Electrician and other scientific journals. In 1899, he would apply for the patent Wireless electro transmission of signals over surfaces.. In 1899, he is said to have applied for a patent on Electro telegraphy by means of condensers and induction coils. Pioneers working on wireless devices came to a limit of distance they could cover. Connecting the antenna directly to the spark gap produced only a damped pulse train.
There were only a few cycles before oscillations ceased. Braun's circuit afforded a much longer sustained oscillation because the energy encountered less losses swinging between coil and Leyden Jars, and by means of inductive antenna coupling the radiator was better matched to the generator. The resultant stronger and less bandwidth consuming signals bridged a much longer distance. Braun invented the phased array antenna in 1905, he described in his Nobel Prize lecture how he arranged three antennas to transmit a directional signal. This invention led to the development of radar, smart antennas, MIMO. Braun's British patent on tuning was used by Marconi in many of his tuning patents. Guglielmo Marconi used Braun's patents. Marconi would admit to Braun himself that he had "borrowed" portions of Braun's work. In 1909, Braun shared the Nobel Prize for physics with Marconi for "contributions to the development of wireless telegraphy." The prize awarded to Braun in 1909 depicts this design. Braun experimented at first at the University of Strasbourg.
Not before long he bridged a distance of 42 km to the city of Mutzig. In spring 1899, accompanied by his colleagues Cantor and Zenneck, went to Cuxhaven to continue their experiments at the North Sea. On 24 September 1900 radio telegraphy signals were exchanged with the island of Heligoland over a distance of 62 km. Light vessels in the river Elbe and a coast station at Cuxhaven commenced a regular radio telegraph service. Braun went to the United States at the beginning of World War I to help defend the German wireless station at Sayville, New York, against attacks by the British-controlled Marconi Corporation. After the US entered the war, Braun was detained, but could move within Brooklyn, New York. Braun died in his house in Brooklyn, before the war ended in 1918. In 1987 the Society for Information Display created the Karl Ferdinand Braun Prize, awarded for an outstanding technical achievement in display technology. U. S.

Coleophora ornatipennella is a small moth of the family Coleophoridae. It is found in the Near East, it is found in China. The wingspan is about 12 millimetres. Forewings are apically falcate, with dark gray stripes; the moth flies in June depending on the location. The larvae feed on Alopecurus, Avena, Bromus, Dactylis glomerata, Holcus and Poa species. Young larvae feed on the developing receptacles of Lamiaceae species and use them to make their first case. Before hibernation, they switch to mining grass blades, they make another case. This is a laterally compressed leaf case of 13–17 millimetres with a mouth angle of about 30°; the colour is yellowish white, but it turns brownish. Larvae can be found from October to May.

Progressive, Black, & Journalists, Inc. is an African-American journalism organization based at the University of Florida, USA. A spin-off from the Association of Black Communicators, PB&J began in an effort to combat the negative minority stereotypes that occur in the media and to sensitize the surrounding community to biased news coverage. However, unlike its predecessor, PB&J strives to achieve this goal through original, student-run programs. Though unaffiliated with any national umbrella organization, all PB&J executive-board directors are required to be registered members of the National Association of Black Journalists. In 2005, The Independent Florida Alligator ran a cartoon drawn by Andy Marlette depicting Condoleezza Rice saying "nigga." African Americans across campus expressed outrage for the newspaper's use of the racial epithet. It brought to the forefront the reality that black students at UF had no media outlet to turn to discuss the racism behind the cartoon. In response, the Association of Black Communicators agreed to continue Zion, a black magazine that only ran a few issues and had not been published for years.
The Black Student Union at UF agreed to help fund the magazine, but as the controversy died down so did interest in the magazine. ABC was forced to abandon the project due to a lack of lack of dedication. Members of ABC, Brian Robertson and Faren Humes, attempted to make a radio show called Truth Be Told in November 2005. However, because of lack of support from the organization, it was never completed. Robertson decided to run for President of ABC in 2006 on the platform that Zion would continue if he were elected, he wanted to complete the radio show. He lost the election to Maya Carpenter after being accused of voter fraud, he left the organization taking half of ABC's executive board with him. In the summer of 2006 Robertson, along with Faren Humes, Stefani Saintonge and Shameka Harris created Progressive and Journalists. Robertson served as its first president. In September 2006 they began naming it BlackListed, they continued the radio show. Strengthen ties among black journalists To provide a media channel for the UF minority student population Promote diversity in the University of Florida College of Journalism and Communications Provide workshops that teach the surrounding community how to gain access to the media Promote career and internship opportunities for students Promote academic excellence by providing a support group for students with an interest in journalism To monitor local media outlets for insensitive statements directly targeted at the minority community and to respond accordingly The newest edition to PB&J, PB&J Productions specializes in video editing and script writing.
PB&J has created commercials, as well as iTunes. Intellectual properties include Detangled. BlackListed Magazine is a free publication and is the only University of Florida black student-run magazine, it pledges to explore black issues pertaining to both UF and the nation along with music and fashion as well. It has eight staff writers with the editor-in-chief position vacant, it encourages students and faculty at UF to contribute. None of the positions are paid. Debuting on September 10, 2007, PB&J is planning to print 500 copies of the first issue with funding from advertisements and donations, they are hoping to increase the size by the third issues. All of the magazine's content plus additional articles will be available on the Web site when the issue is released. BlackListed Magazine publishes an online version, which aims to provide more critical researched but opinion-based articles on issues pertaining to the African-American and Black experience; the current editor, Hananie Albert, accepts submissions via e-mail or through the forthcoming website.
Truth Be Told is a 30-minute bi-monthly podcast distributed through iTunes. Plans are under way to have it as a syndicated show on Magic 101.3 FM in Gainesville, FL. While covering many of the same topics as BlackListed, it differs in its approach by having a comedic tone. Past stories have included such topics as Lydia Washington's Resignation Scandal and the UF African American Studies Program near closure. Guests have included: Al Sharpton, Political Activist Darius Bost, UF IBC Director Sharon Burney, UF AASP Office Manager Lydia Washington, Former UF Student Body Vice-President Scherwin L. Henry, Alachua County Commissioner Rodney Long, Alachua County Commissioner The show is hosted by Myya Passmore, Zory Speights, Faren Humes, & Brian Robertson.
