The four-year, full-time undergraduate program comprises the majority of enrollments at the university and emphasizes instruction in the arts and sciences, plus the professions of engineering, journalism, communication, music, and education. Although a foundation in the liberal arts and sciences is required in all majors, there is no required common core curriculum; individual degree requirements are set by the faculty of each school. Northwestern's full-time undergraduate and graduate programs operate on an approximately 10-week academic quarter system with the academic year beginning in late September and ending in early June. Undergraduates typically take four courses each quarter and twelve courses in an academic year and are required to complete at least twelve quarters on campus to graduate. Northwestern offers honors, accelerated, and joint degree programs in medicine, science, mathematics, engineering, and journalism. The comprehensive doctoral graduate program has high coexistence with undergraduate programs.

How many weeks is one academic quarter at Northwestern?
Output: approximately 10

The "Jeltoqsan" (Kazakh for "December") of 1986 were riots in Alma-Ata, Kazakhstan, sparked by Gorbachev's dismissal of Dinmukhamed Konayev, the First Secretary of the Communist Party of Kazakhstan and an ethnic Kazakh, who was replaced with Gennady Kolbin, an outsider from the Russian SFSR. Demonstrations started in the morning of December 17, 1986, with 200 to 300 students in front of the Central Committee building on Brezhnev Square protesting Konayev's dismissal and replacement by a Russian. Protesters swelled to 1,000 to 5,000 as other students joined the crowd. The CPK Central Committee ordered troops from the Ministry of Internal Affairs, druzhiniki (volunteers), cadets, policemen, and the KGB to cordon the square and videotape the participants. The situation escalated around 5 p.m., as troops were ordered to disperse the protesters. Clashes between the security forces and the demonstrators continued throughout the night in Almaty.
