The Pro Electron standard, the European Electronic Component Manufacturers Association part numbering scheme, begins with two letters: the first gives the semiconductor type (A for germanium, B for silicon, and C for materials like GaAs); the second letter denotes the intended use (A for diode, C for general-purpose transistor, etc.). A 3-digit sequence number (or one letter then 2 digits, for industrial types) follows. With early devices this indicated the case type. Suffixes may be used, with a letter (e.g. "C" often means high hFE, such as in: BC549C) or other codes may follow to show gain (e.g. BC327-25) or voltage rating (e.g. BUK854-800A). The more common prefixes are:
What follows the 2 letters in the part numbering scheme?
A 3-digit sequence number

Indonesia: The Olympic flame reached Jakarta on April 22. The original 20 km relay through Jakarta was cancelled due to "security worries", at the request of the Chinese embassy, and the torch was instead carried round the city main's stadium, as it had been in Islamabad. Several dozen pro-Tibet protesters gathered near the stadium, and were dispersed by the police. The event was held in the streets around the city main's stadium. The cancelling of the relay through the city itself was decided due to security concerns and at the request of the Chinese embassy. Only invitees and journalists were admitted inside the stadium. Protests took place outside the stadium.
Why was the first route not taken?
security worries

At the beginning of the Caliphate or Islamic Empire, the reliance on courts initially confined sponsorship and scholarly activities to major centres. Within several centuries, the development of Muslim educational institutions such as the madrasah and masjid eventually introduced such activities to provincial towns and dispersed them across the Islamic legal schools and Sufi orders. In addition to religious subjects, they also taught the "rational sciences," as varied as mathematics, astronomy, astrology, geography, alchemy, philosophy, magic, and occultism, depending on the curriculum of the specific institution in question. The madaris, however, were not centres of advanced scientific study; scientific advances in Islam were usually carried out by scholars working under the patronage of royal courts. During this time,[when?] the Caliphate experienced a growth in literacy, having the highest literacy rate of the Middle Ages, comparable to classical Athens' literacy in antiquity but on a much larger scale. The emergence of the maktab and madrasa institutions played a fundamental role in the relatively high literacy rates of the medieval Islamic world.
Who traditionally paid for scholars to study natural sciences?
royal courts
