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.
Please sign in to vote on this Guide. Extensive research has shown rear facing a child is up to 500% safer than forward facing. However, many parents are unsure which car seat they should buy. The most expensive seat isn't always the safest! The safest seat is one that allows rear facing for the longest period. A lot of the extra cost in car seats are extras such as cup holders and other features that may make a seat easier to use, but not necessarily increasing it's safety. In this guide I will highlight 3 seats that are recommended for extended rear facing.
