Ü (region)
Ü (Tibetan: དབུས་, Wylie: dbus, ZYPY: Wü ; pronounced w-yu, similar to English word "we") is a geographic division and a historical region in Tibet. Together with Tsang (Tib. གཙང་, gtsang), it forms Central Tibet Ü-Tsang (Tib. དབུས་གཙང་, Wyl. dbus gtsang), which is one of the three Tibetan regions or cholka (cholka-sum). The other two cholka are Kham (Tib. ཁམས་, Wyl. khams) (Dotod) and Amdo (Tib. ཨ༌མདོ;Wyl. a mdo) (Domed). According to a Tibetan saying, "the best religion comes from Ü-Tsang, the best men from Kham, and the best horses from Amdo".
Constituent districts
Taken together, Ü and Tsang are considered to be the center of Tibetan civilization, from historical, cultural, political and economic perspectives. They are centered on the valley of the Yarlung Tsangpo River, which flows eastward at about 3,600 metres (11,800 ft) above sea level. Of this territory, Ü constitutes the eastern portion, up to Sokla Kyao in the east where it borders to Kham. It includes the Lhasa River valley system, where Lhasa is situated, and the Yarlung and Chonggye valleys to the south of the Tsangpo.
Region (mathematics)
In mathematical analysis, the word region usually refers to a subset of 
or 
that is open (in the standard Euclidean topology), connected and non-empty. A closed region is sometimes defined to be the closure of a region.
Regions and closed regions are often used as domains of functions or differential equations.

Notes and references
Regions of New Zealand
New Zealand, although a unitary state, is divided into sixteen regions for devolved local government. Eleven are administered by regional councils (the top tier of local government), and five are administered by unitary authorities, which are territorial authorities (the second tier of local government) that also perform the functions of regional councils. The Chatham Islands Council is similar to a unitary authority, authorised under its own legislation.
Current regions
History and statutory basis
The regional councils are listed in Part 1 of Schedule 2 of the Local Government Act 2002, along with reference to the Gazette notices that established them in 1989. The Act requires regional councils to promote sustainable development – the social, economic, environmental and cultural well-being of their communities.
The current regions and most of their councils came into being through a local government reform in 1989 that took place under the Local Government Act 1974. The regional councils replaced the more than 700 ad hoc bodies that had been formed in the preceding century – roads boards, catchment boards, drainage boards, pest control boards, harbour boards, domain and reserve boards. In addition they took over some roles that had previously been performed by county councils. Auckland Regional Council, formed in 1989, was replaced by Auckland Council, a unitary authority, in 2010.
Franz Lehár
Franz Lehár (30 April 1870 – 24 October 1948) was an Austro-Hungarian composer. He is mainly known for his operettas, of which the most successful and best known is The Merry Widow (Die lustige Witwe).
Biography
Lehár was born in the northern part of Komárom, Kingdom of Hungary, Austria-Hungary (now Komárno, Slovakia), the eldest son of Franz Lehár (senior) (1838–1898), an Austrian bandmaster in the Infantry Regiment No. 50 of the Austro-Hungarian Army and Christine Neubrandt (1849–1906), a Hungarian woman from a family of German descent. He grew up speaking only Hungarian until the age of 12. Later he put a diacritic above the "a" of his father's name "Lehar" to indicate the vowel in the corresponding Hungarian orthography.
Lehár (train)
The Lehár was an express train between Budapest, Hungary, and Vienna, Austria. Introduced in 1979, it was the first eastern European train to become a EuroCity service, in 1988.
The train was operated by the Hungarian State Railways (MÁV) and the Austrian Federal Railways (ÖBB). It was named after Franz Lehár (1870–1948), an Austro-Hungarian composer. It was replaced by a Railjet service in 2008.
History
The Lehár first ran in 1979. The following year, a trip on the train was featured in "Changing Trains", the final episode in Series 1 of Great Railway Journeys of the World, a BBC TV travel documentary. The "Changing Trains" trip, which was the last stage of a longer journey from Paris to Budapest, was also included in the book published to complement the series.
In the book, Eric Robson, the presenter and author of "Changing Trains", described the Lehár as "slow at the best of times", and gave the following account of its border crossing at Hegyeshalom:
Little groups of armed soldiers stand about. I'm reminded that people were shot on this frontier not many weeks before. The train is taken over by an army of workmen, tapping wheels, climbing over bogies and, in the carriages, peering into ceiling cavities and shining torches under the seats. My passport is checked four times and finally stamped with a multi-coloured seal of approval. A girl scuttling about the compartments with an official briefcase demands to know if I have Hungarian money, and scuttles away again before I have a chance to answer.
