The Water Cycle: The U.S. Geological Survey explains what the water cycle is and where water comes from. Animated Water Cycle: This animated water cycle diagram allows kids to click on different parts of the cycle to see how water changes form and moves.
The neuromuscular junction (NMJ) is the site of communication between motor nerve axons and muscle fibres. It is composed of four specialised cell types: motor neurons, Schwann cells, muscle fibres and the recently discovered kranocytes.
As the name implies, the npn BJT is simply an hunk of p-type Silicon sandwiched between two slices of n-type material: Each of the three Silicon regions has one terminal electrode connected to it, and thus the npn BJT is a three terminal device.1/28/2004 section 5_1 BJT Device Structure and Physical Operation blank 1/2 Jim Stiles The Univ. of Kansas Dept. of EECS 5.1 BJT Device Structure and Physical Operation Reading Assignment: pp. 377-392 Another kind of transistor is the Bipolar Junction Transistor (BJT).
