The Partyja BPF (Belarusian Popular Front) was established in 1988 as a political party and cultural movement for democracy and independence, à la the Baltic republics’ popular fronts. The discovery of mass graves in Kurapaty outside Minsk by historian Zianon Pazniak, the Belarusian Popular Front’s first leader, gave additional momentum to the pro-democracy and pro-independence movement in Belarus. It claimed that the NKVD performed secret killings in Kurapaty. Initially the Front had significant visibility because its numerous public actions almost always ended in clashes with the police and the KGB.
When did The Partyja BDF start?
****
The answer: 1988

Mechanically controlled variable capacitors allow the plate spacing to be adjusted, for example by rotating or sliding a set of movable plates into alignment with a set of stationary plates. Low cost variable capacitors squeeze together alternating layers of aluminum and plastic with a screw. Electrical control of capacitance is achievable with varactors (or varicaps), which are reverse-biased semiconductor diodes whose depletion region width varies with applied voltage. They are used in phase-locked loops, amongst other applications.
What do mechanically controlled variable capacitors enable to be modified?
****
The answer: the plate spacing

Early research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it failed to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[dubious – discuss] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase.[citation needed] A more stringent study conducted in 1999 by Harvard University estimated the natural human rhythm to be closer to 24 hours, 11 minutes: much closer to the solar day but still not perfectly in sync.
What did early research show people preferred as a day length?
****
The answer: 25 hours

Until 18 December 2010, Eton College was an exempt charity under English law (Charities Act 1993, Schedule 2). Under the provisions of the Charities Act 2006, it is now an excepted charity, and fully registered with the Charities Commission, and is now one of the 100 largest charities in the UK. As a charity, it benefits from substantial tax breaks. It was calculated by the late David Jewell, former Master of Haileybury, that in 1992 such tax breaks saved the School about £1,945 per pupil per year, although he had no direct connection with the School. This subsidy has declined since the 2001 abolition by the Labour Government of state-funded scholarships (formerly known as "assisted places") to independent schools. However, no child attended Eton on this scheme, meaning that the actual level of state assistance to the School has always been lower. Eton's retiring Head Master, Tony Little, has claimed that the benefits that Eton provides to the local community free of charge (use of its facilities, etc.) have a higher value than the tax breaks it receives as a result of its charitable status. The fee for the academic year 2010–2011 was £29,862 (approximately US$48,600 or €35,100 as of March 2011), although the sum is considerably lower for those pupils on bursaries and scholarships.
How much did estimated tax breaks save per student in 1992?
****
The answer:
£1,945 per pupil per year
