Mar 15, 2012 China_Helicopter used to inspect drought situation in Yunnan, SW China
Forest police used a helicopter for the first time to air inspect the drought situation of a reservoir in Kunming, capital of southwest China's Yunnan Province recently as the province has been hit by drought for three consecutive years.The helicopter mainly inspected Yunlong reservoir which is located in Luquan County, 138 km away from the provincial capital city of Kunming, and is a major project in the development of China's western regions. The reservoir has a capacity of 484 million cubic meters.
The helicopter flew 3000 meters high smoothly above sea level and and more than 1000 meters above ground, and then hovered 500 meters above the reservoir. The white cylindrical device attached beneath the helicopter, dubbed Sky Eye, is the infrared camera for collecting and storing information.
Through air inspection, we can see that the water level in the reservoir this year is the lowest in three consecutive years and forest fire prevention task is very rigorous, said Rong Youlin, deputy commander of the Kunming Forest Fire Prevention Headquarters.
In addition, a police patrol vessel has also joined the effort to prevent forest fire and protect water resources.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Yunnan (云南) is a province of the People's Republic of China, located in the far southwest of the country. It spans approximately 394,000 square kilometres (152,000 sq mi) and has a population of 45.7 million (as of 2009). The capital of the province is Kunming, formerly also known as Yunnan. The province borders the Chinese provinces Guangxi, Guizhou, Sichuan, and the Tibet Autonomous Region, and the countries Vietnam, Laos, and Myanmar.
Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys as much as 3,000 metres (9,800 ft). Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, zinc and tin are the largest in China, and there are also major reserves of copper and nickel.
The Han Empire first recorded diplomatic relations with the province at the end of the 2nd century BC. It became the seat of a Sino-Tibetan-speaking kingdom of Nanzhao in the 8th century AD. Nanzhao was multi-ethnic, but the elite most-likely spoke a northern dialect of Yi. The Mongols conquered the region in the 13th century, with local control exercised by warlords until the 1930s. From the Yuan dynasty onward, the area was part of a central-government sponsored population movement towards the southwestern frontier, with two major waves of migrants arriving from Han-majority areas in northern and southeast China. As with other parts of China's southwest, Japanese occupation in the north during World War II forced another migration of majority Han people into the region. These two waves of migration contributed to Yunnan being one of the most ethnically diverse provinces of China, with ethnic minorities accounting for about 34 percent of its total population. Major ethnic groups include Yi, Bai, Hani, Zhuang, Dai and Miao.

In the beginning of the Golden Age, American radio network programs were almost exclusively broadcast live, as the national networks prohibited the airing of recorded programs until the late 1940s because of the inferior sound quality of phonograph discs, the only practical recording medium. As a result, prime-time shows would be performed twice, once for each coast. However, reference recordings were made of many programs as they were being broadcast, for review by the sponsor and for the network's own archival purposes. With the development of high-fidelity magnetic wire and tape recording in the years following World War II, the networks became more open to airing recorded programs and the prerecording of shows became more common.Local stations, however, had always been free to use recordings and sometimes made substantial use of prerecorded syndicated programs distributed on pressed (as opposed to individually recorded) transcription discs.
Recording was done using a cutting lathe and acetate discs. Programs were normally recorded at 33⅓ rpm on 16 inch discs, the standard format used for such electrical transcriptions from the early 1930s through the 1950s. Sometimes, the groove was cut starting at the inside of the disc and running to the outside. This was useful when the program to be recorded was longer than 15 minutes so required more than one disc side. By recording the first side outside in, the second inside out, and so on, the sound quality at the disc change-over points would match and result in a more seamless playback. An inside start also had the advantage that the thread of material cut from the disc's surface, which had to be kept out of the path of the cutting stylus, was naturally thrown toward the center of the disc so was automatically out of the way. When cutting an outside start disc, a brush could be used to keep it out of the way by sweeping it toward the middle of the disc. Well-equipped recording lathes used the vacuum from a water aspirator to pick it up as it was cut and deposit it in a water-filled bottle. In addition to convenience, this served a safety purpose, as the cellulose nitrate thread was highly flammable and a loose accumulation of it combusted violently if ignited.
Most recordings of radio broadcasts were made at a radio network's studios, or at the facilities of a network-owned or affiliated station, which might have four or more lathes. A small local station often had none. Two lathes were required to capture a program longer than 15 minutes without losing parts of it while discs were flipped over or changed, along with a trained technician to operate them and monitor the recording while it was being made. However, some surviving recordings were produced by local stations.[7][8]
When a substantial number of copies of an electrical transcription were required, as for the distribution of a syndicated program, they were produced by the same process used to make ordinary records. A master recording was cut, then electroplated to produce a stamper from which pressings in vinyl (or, in the case of transcription discs pressed before about 1935, shellac) were molded in a record press.
