An estimated 20,000 Somalis emigrated to the U.S. state of Minnesota some ten years ago and the Twin Cities (Minneapolis and Saint Paul) now have the highest population of Somalis in North America. The city of Minneapolis hosts hundreds of Somali-owned and operated businesses offering a variety of products, including leather shoes, jewelry and other fashion items, halal meat, and hawala or money transfer services. Community-based video rental stores likewise carry the latest Somali films and music. The number of Somalis has especially surged in the Cedar-Riverside area of Minneapolis.
About how many Somalis moved to Minnesota ten years ago?

Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, "Trouve". After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". With little convincing, visitors believed his dog could articulate "How are you grandma?" More indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". However, these initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance.
What did Bell  instruct his dog to do?
growl continuously

Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p–n–p transistor). This construction produces two p–n junctions: a base–emitter junction and a base–collector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).
What was the first mass-produced transistor?
