Prostaglandin analogues are molecules that behave like prostaglandins by binding to prostaglandin receptors. Misoprostol is the most commonly used prostaglandin analogue.
oxytocin and prostaglandin (oxitocin sends positive feedback to prostaglandin)

Prostaglandin E2, which softens the cervix so it can dilate or open in preparation for childbirth.
Yes.
Wind power, hydropower, solar energy
Prostaglandin
An antiprostaglandin is something which inhibits prostaglandin.

You would have to know the Power Factor, normally designated PF. MVA x PF = MW. If the PF is unity then MVA = MW. A PF of UNITY suggest the load is purely resistive with neither capacitive nor inductive components in the load or source. Of course this can mean such components have been balanced artificially.
The sun is the initial (primary) energy source for life. Ingestion and digestion of a food source is an animal's primary source of energy.
