Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Bosnia and Herzegovina

Bosnia and Herzegovina (ⁱ/ˈbɒzniə ənd ˌhɛərtsəɡoʊˈviːnə, -ˌhɜːrt-, -ɡə-/ or /ˌhɜːrtsəˈɡɒvᵻnə/;Bosnian, Croatian and Serbian Latin script: Bosna i Hercegovina, Bosnian and Serbian Cyrillic script: Боснa и Херцеговина; pronounced [bôsna i xěrt͡seɡoʋina]), sometimes called Bosnia-Herzegovina or Bosnia & Herzegovina, abbreviated BiH or B&H, and in short often known informally as Bosnia, is a country in Southeastern Europe located on the Balkan Peninsula. Sarajevo is the capital and largest city. Bordered by Croatia to the north, west, and south; Serbia to the east; Montenegro to the southeast; and the Adriatic Sea to the south, with a coastline about 20 kilometres (12 miles) long surrounding the city of Neum. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a geographically larger region and has a moderate continental climate, bookended by hot summers and cold and snowy winters. The southern tip of the country has a Mediterranean climate and plain topography.

Serbs of Bosnia and Herzegovina

The Serbs of Bosnia and Herzegovina (Serbian: Срби у Босни и Херцеговини / Srbi u Bosni i Hercegovini) are one of the three constitutive nations of the country, predominantly residing in the political-territorial entity of Republika Srpska. In the other entity Federation of Bosnia and Herzegovina Serbs mostly live in Drvar, Glamoč, Bosansko Grahovo and Bosanski Petrovac. They are frequently referred to as Bosnian Serbs (Serbian: Босански Срби / Bosanski Srbi) in English, regardless of whether they are from Bosnia or Herzegovina. They are also known by regional names such as Krajišnici ("frontiersmen" of Bosanska Krajina), Semberci (Semberians), Bosanci (Bosnians), Hercegovci (Herzegovinians).

Demographics

The 1991 population census registered 1,366,104 Serbs or 31.2% of the total population of Bosnia and Herzegovina. Census was held in October 2013 with ethnicity data yet to be published. Bosnian Serbs are the most territorially widespread nation of Bosnia and Herzegovina. The vast majority live on the territory of the Republika Srpska, where they constitute around 88% of population. The majority of Bosnian Serbs are adherents of the Serbian Orthodox Church, while some are atheists. The Serbs of Bosnia and Herzegovina speak the Serbian language in its Ijekavian accent, similar to that of Serbs of Montenegro and Croatia, and also to the language of Bosniaks and Bosnian Croats.

Banja Luka

Banja Luka (Serbian Cyrillic: Бања Лука, pronounced [bǎɲa lǔːka]) or Banjaluka (Serbian Cyrillic: Бањалука) is the second largest city in Bosnia and Herzegovina after the capital Sarajevo and is the largest city of the Republika Srpska entity. Traditionally, it has been the center of the Bosanska Krajina region, located in the northwestern part of the country. It is home of the University of Banja Luka, as well as numerous state and entity institutions of Bosnia and Herzegovina. The city lies on the River Vrbas and is well known in the countries of the former Yugoslavia for being full of tree-lined avenues, boulevards, gardens, and parks. According to the 2013 census the Settlement of Banja Luka has 150,997 inhabitants, while the City of Banja Luka, which represents Banja Luka's wider area (municipality), has 199,191 inhabitants.

Name

The name "Banja Luka" was first mentioned in a document dated 6 February 1494, by Vladislav II. The name is interpreted as "Ban's meadow", from the words ban ("a medieval dignitary"), and luka ("a valley" or "a meadow"). The identity of the ban and the meadow in question remain uncertain, and popular etymology combines the modern words banja ("bath" or "spa"), or bajna ("marvelous") and luka ("port"). A different interpretation is suggested by the Hungarian name "Lukácsbánya", i.e. "Luke's Mine", which is also the meaning of Slovak "Banja Luka". In modern usage, the name is pronounced and usually declined (u Banjaluci) as one word, and often written as such; the citizens reportedly prefer the more correct form with inflected adjective (u Banjoj Luci).
