Question: In September 1961, while working at Texas Instruments in Dallas, Texas, James R. Biard and Gary Pittman discovered near-infrared (900 nm) light emission from a tunnel diode they had constructed on a GaAs substrate. By October 1961, they had demonstrated efficient light emission and signal coupling between a GaAs p-n junction light emitter and an electrically-isolated semiconductor photodetector. On August 8, 1962, Biard and Pittman filed a patent titled "Semiconductor Radiant Diode" based on their findings, which described a zinc diffused p–n junction LED with a spaced cathode contact to allow for efficient emission of infrared light under forward bias. After establishing the priority of their work based on engineering notebooks predating submissions from G.E. Labs, RCA Research Labs, IBM Research Labs, Bell Labs, and Lincoln Lab at MIT, the U.S. patent office issued the two inventors the patent for the GaAs infrared (IR) light-emitting diode (U.S. Patent US3293513), the first practical LED. Immediately after filing the patent, Texas Instruments (TI) began a project to manufacture infrared diodes. In October 1962, TI announced the first LED commercial product (the SNX-100), which employed a pure GaAs crystal to emit a 890 nm light output. In October 1963, TI announced the first commercial hemispherical LED, the SNX-110.
Is there an answer to this question:  What was the first non-practical LED?

Answer: unanswerable


Question: In the 1970s and 1980s there were reports of his making sexual advances toward female reporters and members of his entourage. After the civil war, more serious charges came to light. Annick Cojean, a journalist for Le Monde, wrote in her book, Gaddafi's Harem that Gaddafi had raped, tortured, performed urolagnia, and imprisoned hundreds or thousands of women, usually very young. Another source—Libyan psychologist Seham Sergewa—reported that several of his female bodyguards claim to have been raped by Gaddafi and senior officials. After the civil war, Luis Moreno Ocampo, prosecutor for the International Criminal Court, said there was evidence that Gaddafi told soldiers to rape women who had spoken out against his regime. In 2011 Amnesty International questioned this and other claims used to justify NATO's war in Libya.
Is there an answer to this question: What is the nationality of Seham Sergewa?

Answer: Libyan


Question: Neptune has a planetary ring system, though one much less substantial than that of Saturn. The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. The three main rings are the narrow Adams Ring, 63,000 km from the centre of Neptune, the Le Verrier Ring, at 53,000 km, and the broader, fainter Galle Ring, at 42,000 km. A faint outward extension to the Le Verrier Ring has been named Lassell; it is bounded at its outer edge by the Arago Ring at 57,000 km.
Is there an answer to this question: Where is the La Verrier ring from the center of Neptune?

Answer: 53,000 km


Question: Police development-aid to weak, failed or failing states is another form of transnational policing that has garnered attention. This form of transnational policing plays an increasingly important role in United Nations peacekeeping and this looks set to grow in the years ahead, especially as the international community seeks to develop the rule of law and reform security institutions in States recovering from conflict (Goldsmith and Sheptycki, 2007) With transnational police development-aid the imbalances of power between donors and recipients are stark and there are questions about the applicability and transportability of policing models between jurisdictions (Hills, 2009).
Is there an answer to this question: What kind of countries get assistance with policing?

Answer:
weak, failed or failing states
