<P0-S0> the pembina river is a tributary of the red river of the north, approximately long, in southern manitoba in canada and northeastern north dakota in the united states. <P0-S1> it drains an area (about 8500 square kilometers) of the prairie country along the canada–us border, threading the manitoba-north dakota border eastward to the red river. <P0-S2> via the red river, lake winnipeg and the nelson river, it is part of the watershed of hudson bay. <SEP> <P1-S0> Major cities include Nur-Sultan, Almaty, Karagandy, Shymkent, Atyrau, and Oskemen. <P1-S1> It lies between latitudes 40° and 56° N, and longitudes 46° and 88° E. While located primarily in Asia, a small portion of Kazakhstan is also located west of the Urals in Eastern Europe.Kazakhstan's terrain extends west to east from the Caspian Sea to the Altay Mountains and north to south from the plains of Western Siberia to the oases and deserts of Central Asia. <P1-S2> The Kazakh Steppe (plain), with an area of around 804,500 square kilometres (310,600 sq mi), occupies one-third of the country and is the world's largest dry steppe region. <P1-S3> It shares borders of 6,846 kilometres (4,254 mi) with Russia, 2,203 kilometres (1,369 mi) with Uzbekistan, 1,533 kilometres (953 mi) with China, 1,051 kilometres (653 mi) with Kyrgyzstan, and 379 kilometres (235 mi) with Turkmenistan. <P1-S4> The steppe is characterised by large areas of grasslands and sandy regions. <P1-S5> Major seas, lakes and rivers include the Aral Sea, Lake Balkhash and Lake Zaysan, the Charyn River and gorge and the Ili, Irtysh, Ishim, Ural and Syr Darya rivers. <SEP> <P2-S0> The Belyayev circle () was a society of Russian musicians who met in Saint Petersburg, Russia between 1885 and 1908, and whose members included Nikolai Rimsky-Korsakov, Alexander Glazunov, Vladimir Stasov, Anatoly Lyadov, Alexander Ossovsky, Witold Maliszewski, Nikolai Tcherepnin, Nikolay Sokolov, Alexander Winkler among others. <P2-S1> The circle was named after Mitrofan Belyayev, a timber merchant and amateur musician who became a music philanthropist and publisher after hearing the music of the teenage Glazunov. <SEP> <P3-S0> Chopin's music was used in the 1909 ballet Chopiniana, choreographed by Michel Fokine and orchestrated by Alexander Glazunov. <P3-S1> Sergei Diaghilev commissioned additional orchestrations—from Stravinsky, Anatoly Lyadov, Sergei Taneyev and Nikolai Tcherepnin—for later productions, which used the title Les Sylphides. <SEP> <P4-S0> there are generally three possible arrangements by which a country can have a single border. <P4-S1> the first is with a divided island such a haiti and the dominican republic, or ireland and the united kingdom. <P4-S2> the second is a peninsular relationship, where the first country borders the second and is otherwise surrounded by sea, while the second country borders other countries, as with portugal and spain, denmark and germany, or canada and the united states. <P4-S3> the third is the circumstance where the first country is a small country that is landlocked and completely surrounded by the second, larger country, as with the vatican and italy, or lesotho and south africa.
