Question: With nitrides containing aluminium, most often AlGaN and AlGaInN, even shorter wavelengths are achievable. Ultraviolet LEDs in a range of wavelengths are becoming available on the market. Near-UV emitters at wavelengths around 375395 nm are already cheap and often encountered, for example, as black light lamp replacements for inspection of anti-counterfeiting UV watermarks in some documents and paper currencies. Shorter-wavelength diodes, while substantially more expensive, are commercially available for wavelengths down to 240 nm. As the photosensitivity of microorganisms approximately matches the absorption spectrum of DNA, with a peak at about 260 nm, UV LED emitting at 250270 nm are to be expected in prospective disinfection and sterilization devices. Recent research has shown that commercially available UVA LEDs (365 nm) are already effective disinfection and sterilization devices. UV-C wavelengths were obtained in laboratories using aluminium nitride (210 nm), boron nitride (215 nm) and diamond (235 nm).
Is there an answer to this question: Shorter wavelength diodes provide wavelengths as low as what?

Answer: 240 nm

Question: A fundamental part of Gaddafi's ideology was anti-Zionism. He believed that the state of Israel should not exist, and that any Arab compromise with the Israeli government was a betrayal of the Arab people. In large part due to their support of Israel, Gaddafi despised the United States, considering the country to be imperialist and lambasting it as "the embodiment of evil." Rallying against Jews in many of his speeches, his anti-Semitism has been described as "almost Hitlerian" by Blundy and Lycett. From the late 1990s onward, his view seemed to become more moderate. In 2007, he advocated the Isratin single-state solution to the IsraeliPalestinian conflict, stating that "the [Israel-Palestine] solution is to establish a democratic state for the Jews and the Palestinians... This is the fundamental solution, or else the Jews will be annihilated in the future, because the Palestinians have [strategic] depth." Two years later he argued that a single-state solution would "move beyond old conflicts and look to a unified future based on shared culture and respect."
Is there an answer to this question: Who compared Gaddafi to Hitler?

Answer: Blundy and Lycett

Question: Numerous plays are put on every year at Eton College; there is one main theatre, called the Farrer (seating 400) and 2 Studio theatres, called the Caccia Studio and Empty Space (seating 90 and 80 respectively). There are about 8 or 9 house productions each year, around 3 or 4 "independent" plays (not confined solely to one house, produced, directed and funded by Etonians) and three school plays, one specifically for boys in the first two years, and two open to all years. The School Plays have such good reputations that they are normally fully booked every night. Productions also take place in varying locations around the School, varying from the sports fields to more historic buildings such as Upper School and College Chapel.
Is there an answer to this question: Do the plays sport high attendance rates?

Answer: fully booked every night

Question: Multiracial people who wanted to acknowledge their full heritage won a victory of sorts in 1997, when the Office of Management and Budget (OMB) changed the federal regulation of racial categories to permit multiple responses. This resulted in a change to the 2000 United States Census, which allowed participants to select more than one of the six available categories, which were, in brief: "White," "Black or African American," "Asian," "American Indian or Alaskan Native," "Native Hawaiian or other Pacific Islander," and "Other." Further details are given in the article: Race (U.S. census). The OMB made its directive mandatory for all government forms by 2003.
Is there an answer to this question: What office is responsible for the census form changes?

Answer:
the Office of Management and Budget (OMB)
