Why does eduion reduce crime?
· Reduced criminality is a beneficial consequence of eduion policies that raise the school leaving age. There are two possible explanations: First, extra time spent in the eduion system increases labor market prospects and makes crime relatively less profitable (the longerterm effect).
Reactions of Alcohols
Reduction of Alcohols Normally an alcohol cannot be directly reduced to an alkane in one step. The –OH group is a poor leaving group so hydride displacement is not a good option – however the hydroxyl group is easily converted into other groups that are superior leaving groups, and allow reactions to proceed. OH KMn O 4, b a s e O OH H OH O ...

The Physics of Engine Cylinder Bank Angles
· The flatfour fires at 180degree intervals, and its V angle is 180 degrees, which leads to a balance of firing forces. The flatfour, in fact, balances all three of the different types of forces.
Worm gears: What are they and where are they used?
· The primary benefit of worm gears is their ability to provide high reduction ratios and correspondingly high torque multipliion. They can also be used as speed reducers in low to mediumspeed appliions. And, because their reduction ratio is based on the number of gear teeth alone, they are more compact than other types of gears.
