The compressor clutch is typically a combination of three parts; the hub, pulley, and coil. The hub (sometime referred to as the clutch) is the very front part, a round metal piece. Next is the pulley, which is where the belt rides. Finally, under the pulley is the coil, also called a field coil. The coil contains a tighly wound copper wire, and is essentially an electromagnet.
Lantus is a long-acting insulin that is designed to be taken just once a day. (Click Lantus Uses for more information, including possible off-label uses.). It is manufactured by sanofi-aventis.
Lantus and Levemir have a lot in common. Both are basal insulin formulas, which means that they last for a long time in the body and act as background insulin, with a slow feed that mimics the constant low output of insulin produced by a healthy pancreas.
