Input: Read this: The structure of QD-LEDs used for the electrical-excitation scheme is similar to basic design of OLEDs. A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths and narrow bandwidth is also beneficial as excitation sources for fluorescence imaging. Fluorescence near-field scanning optical microscopy (NSOM) utilizing an integrated QD-LED has been demonstrated.
Question:  What is one material used in non-electrical-excitation?

Output: unanswerable


QUES: These events and the disagreements that arose from them within the Whig Party, led to its break-up and to the rupture of Burke's friendship with Fox. In debate in Parliament on Britain's relations with Russia, Fox praised the principles of the revolution, although Burke was not able to reply at this time as he was "overpowered by continued cries of question from his own side of the House". When Parliament was debating the Quebec Bill for a constitution for Canada, Fox praised the revolution and criticised some of Burke's arguments, such as hereditary power. On 6 May 1791, during another debate in Parliament on the Quebec Bill, Burke used the opportunity to answer Fox, and to condemn the new French Constitution and "the horrible consequences flowing from the French idea of the Rights of Man". Burke asserted that those ideas were the antithesis of both the British and the American constitutions. Burke was interrupted, and Fox intervened, saying that Burke should be allowed to carry on with his speech. A vote of censure was moved against Burke, however, for noticing the affairs of France, which was moved by Lord Sheffield and seconded by Fox. Pitt made a speech praising Burke, and Fox made a speech—both rebuking and complimenting Burke. He questioned the sincerity of Burke, who seemed to have forgotten the lessons he had learned from him, quoting from Burke's own speeches of fourteen and fifteen years before.

Which constitution did Burke condemn on May 6, 1791?
What is the answer?
ANS: French


QUES: The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate – though there is no evidence at present to suggest they are – the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
Why does relying on these effects create concern?

ANS: If these theories are slightly inaccurate


Thousands of Soviet troops were sent to the Fergana Valley, southeast of the Uzbek capital Tashkent, to re-establish order after clashes in which local Uzbeks hunted down members of the Meskhetian minority in several days of rioting between June 4–11, 1989; about 100 people were killed. On June 23, 1989, Gorbachev removed Rafiq Nishonov as First Secretary of the Communist Party of the Uzbek SSR and replaced him with Karimov, who went on to lead Uzbekistan as a Soviet Republic and subsequently as an independent state.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who replaced Nishonov?
Ah, so.. Karimov


Question: Greece is a democratic and developed country with an advanced high-income economy, a high quality of life and a very high standard of living. A founding member of the United Nations, Greece was the tenth member to join the European Communities (precursor to the European Union) and has been part of the Eurozone since 2001. It is also a member of numerous other international institutions, including the Council of Europe, NATO,[a] OECD, OIF, OSCE and the WTO. Greece, which is one of the world's largest shipping powers, middle powers and top tourist destinations, has the largest economy in the Balkans, where it is an important regional investor.
Try to answer this question if possible: Which political philosophy does Greece follow?
Answer: democratic


Context and question: Between October 14–16, 1964, Leonid Brezhnev and a small cadre of high-ranking Communist Party officials, deposed Khrushchev as Soviet government leader a day after Voskhod 1 landed, in what was called the "Wednesday conspiracy". The new political leaders, along with Korolev, ended the technologically troublesome Voskhod program, cancelling Voskhod 3 and 4, which were in the planning stages, and started concentrating on the race to the Moon. Voskhod 2 would end up being Korolev's final achievement before his death on January 14, 1966, as it would become the last of the many space firsts that demonstrated the USSR's domination in spacecraft technology during the early 1960s. According to historian Asif Siddiqi, Korolev's accomplishments marked "the absolute zenith of the Soviet space program, one never, ever attained since." There would be a two-year pause in Soviet piloted space flights while Voskhod's replacement, the Soyuz spacecraft, was designed and developed.
Korolev died on what date?
Answer:
January 14, 1966
