1.The village school had no such positions as Principal or Class Monitor; so we conferred the title "King" on the leader. 
3.Where do the female prefects bathe? And does the mermaid on the wall watch people as they take baths?
4.This paper gives the formula for estimating a bond length of any homo-or heteronuclear multiple bond of any order. Under schomaker and Stevenson rule, the results is equal to the experimental bond distances.
6.Harry will learn more about them, and how they died, from Mad-Eye Moody at the prefect party in Grimmauld Place, a little over four years from now.
7.September. Begins his seventh year at Hogwarts. Tom is Prefect, Head Boy, and receives a Medal for Magical Merit.
8.Single mode emission with a side mode suppression ratio greater than 20dB for uncoated lasers is realized. Record low threshold currents of 50 and 80mA and record short cavity lengths of 145 and 170μm are achieved for λ≈5.4μm and λ≈7.84μm devices,respectively,in pulsed mode.
9.There is a tremendous difference in strategy between playing Deity and Chieftain.
10.The adsorption energy of H~+ on different coal surface, along with correlated chemical bond length, order, and net charge distribution were obtained by means of ZINDO quantum chemical calculation of model compounds.
