Radio Nacional Del Perú
Radio Nacional del Perú is the first and the oldest radio station in Peru. It had its origins in the private station Lima OAX-AM, owned by the Peruvian Broadcasting Company, which was founded in 1924 by César A. Coloma, Santiago Acuña among others, and started broadcasting on June 15, 1925. Background The OAX official performance was linked to the sale of "''Marconi''" brand radio receptors. From 9:00 to 11:00, it broadcast non-professionally formatted programs including readings, opera arias and classical music recitals, all of them performed by amateurs. ''OAX'' was officially launched by president Augusto B. Leguía on June 20 1925. Radio programs were still something new in Lima, but they could not compete with the then live night shows. Therefore, OAX soon declared bankruptcy and, by government resolution of September 6 1926, the Peruvian State took over under the administration of Mr. Joaquín de Azambuja who, as he was instructed, turned the company into a bro ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have also greatly shrunk due to competition from FM (FM broadcasting, frequency modulation) radio, Digital audio broadcasting, Digital Audio Broadcasting (DAB), satellite radio, HD Radio, HD (digi ...

Pontifical Catholic University Of Peru
Pontifical Catholic University of Peru ( es, link=no, Pontificia Universidad Católica del Perú, PUCP) is a private university in Lima, Peru. It was founded in 1917 with the support and approval of the Catholic Church, being the oldest private institution of higher learning in the country. The person who dealt the necessary formalities was Catholic priest Jorge Dintilhac. The Peruvian historian and politician José de la Riva-Agüero y Osma would become his main benefactor by leaving him most of his assets as an inheritance, as it was then a more religious educational institution and linked to the Catholic Church; in contrast to his alma mater and original destination of his inheritance, the National University of San Marcos, where Riva-Agüero considered that liberal ideas and atheism predominated here. In July 2012, after an apostolic visitation, begun earlier, in 2011, by Peter Erdo, Archbishop of Esztergom-Budapest, Hungary, the Holy See withdrew from the university the r ...

Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30 De Enero
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...
