Accra

Accra /əˈkrɑː/ is the capital and largest city of Ghana, with an estimated urban population of 2.27 million as of 2012. It is also the capital of the Greater Accra Region and of the Accra Metropolitan District, with which it is coterminous. Accra is furthermore the anchor of a larger metropolitan area, the Greater Accra Metropolitan Area (GAMA), which is inhabited by about 4 million people, making it the second-largest metropolitan conglomeration in Ghana by population, and the eleventh-largest metropolitan area in Africa.

Accra stretches along the Ghanaian Atlantic coast and extends north into Ghana's interior. Originally built around a port, it served as the capital of the British Gold Coast between 1877 and 1957. Once merely a 19th-century suburb of Victoriaborg, Accra has since transitioned into a modern metropolis; the city's architecture reflects this history, ranging from 19th-century architecture buildings to modern skyscrapers and apartment blocks.

Accra serves as the Greater Accra region's economic and administrative hub. It is furthermore a centre of a wide range of nightclubs, restaurants, and hotels. Since the early 1990s, a number of new buildings have been built, including the multi-storey French-owned Novotel hotel. The city's National Theatre was built with Chinese assistance. In 2010, the Globalization and World Cities Research Network designated Accra a Gamma-minus-level world city, indicating a growing level of international influence and connectedness.

List of Farm to Market Roads in Texas (1–99)

Farm to Market Roads in Texas are owned and maintained by the Texas Department of Transportation (TxDOT).

FM 1

Farm to Market Road 1 (FM 1) was the first farm-to-market road to be designated in Texas, at the request of local industry for a paved road. The 18.6-mile (29.9 km) road provides access to rural areas of East Texas from U.S. Highway 96.

FM 2

Farm to Market Road 2 is a farm to market road in rural southeastern Grimes County, Texas. FM 2 was designated on July 29, 1941.

FM 2 begins in the village of Courtney, at a county road near the Washington County line. It runs along the northeastern edge of the TDCJ O.L. Luther Prison Unit. It then continues through rural farmland in Grimes County. It then travels east, crossing SH 6 and passing several prison farms before ending at FM 362.

FM 2 was designated in 1941 from Courtney east to SH 6. The designation was extended to FM 362 on May 2, 1962, which added approximately 4.4 miles to FM 2.

FM 3

Farm to Market Road 3 is a farm to market road in southwestern Leon County, Texas. FM 3 was designated in March 1942.

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.
