Tucuruí Transmission Line
The Tucuruí transmission line ( pt, Linhão de Tucuruí) is a hydroelectric power line that leads north from the Tucuruí Dam in Pará, Brazil and crosses the Amazon River. From there the eastern branch leads to Macapá in Amapá and the western branch leads to Manaus in Amazonas. The towers supporting the span across the Amazon River are nearly as high as the Eiffel Tower. Work to extend the line from Manaus north to Boa Vista, Roraima, is due to complete in 2018. There were delays in issuing the environmental permits and then legal challenges since the line crosses the territory of indigenous people who had not been consulted. Although efforts have been made to avoid environmental damage, there has been controversy about the impact of construction and of the tower maintenance corridor. Background Until recently the areas of Brazil north of the Amazon, including all of the states of Amapá and Roraima, and parts of the states of Pará and Amazonas, were not connected to the Br ...

Uatumã River
The Uatumã River (sometimes spelled Uatamã) is a river flowing through the state of Amazonas in Brazil. It is a northern tributary of the Amazon River, and known for its extensive peacock bass population. It is a blackwater river. The river flows through the Uatuma-Trombetas moist forests ecoregion. During the wet season starting in December, water levels can rise some 25 to 40 feet. Water levels have been strongly affected by the building of the controversial Balbina Dam on the river in the mid to late 1980s to generate electricity. The hydroelectric dam generates an average of 112.2 MW of electricity from the river system and floods a total of 2360 km2 of rainforest around the Uatumã river. From the point where the river emerges from the dam it defines the east boundary of the Caverna do Maroaga Environmental Protection Area, established in 1990. The Uatumã Biological Reserve established in 1990 is a nature reserve around the river in the municipalities of São ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gigabit Per Second
In telecommunications, data-transfer rate is the average number of bits (bitrate), characters or symbols (baudrate), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). For example, the data rates of modern residential high-speed Internet connections are commonly expressed in megabits per second (Mbit/s). Standards for unit symbols and prefixes Unit symbol The ISQ symbols for the bit and byte are ''bit'' and ''B'', respectively. In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a ''1 Mbps'' connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per second), or about 0.1192 MiB/s (mebibyte per second).
