By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for âmany parts.â Each of those parts is scientists call a monomer (which in Greek means âone partâ). Think of a polymer as a chain, with each of its links a monomer.
Save this Post. 3. Re: Rear facing seats in United 747-400 business class. Jan 14, 2013, 7:17 PM. I would still go with the upper deck, even with the 3 less length. The main business cabin on the 744 feels rather cramped in business class. The upper deck seats are much quieter and private. You also have the additional storage compartments along the window side. I have travelled on this plane, but in forward facing seats. We could only see the passengers across the aisle, not those in front of us. The upper deck was quiet, the side storage compartments excellent and the seat pitch more than adequate.
Rear Facing Car Seat Myths Busted. Itâs hopefully common knowledge now that rear facing in the car is the safest way for toddlers to ride. As a child passenger safety technician, Iâve heard all the reasons that parents choose to forward face too early, and Iâd like to provide some answers to those car seat myths here. Hopefully, this guide will help keep your child rear facing as long as possible! Myth #1: My child is too big! Even big kids can rear face past age two! The lovely young lady pictured here is 28 months and in the 90th percentile for both weight and height at 33 lbs and 37â³ tall. She is happily rear facing in a Safety 1st Complete Air, which has a limit of 40 lbs or 40â³.
