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.
Birth - 2 Years: Rear-Facing. All children under age 2 must be properly secured in a rear-facing car seat. Rear-facing is the safest way for small children to travel. They should remain rear-facing until they reach 2 years of age or until they exceed the height and weight limit of the car seat.
