Dinoprostone is available as Prepidil and Cervidil. Prepidil is a gel thatâs rubbed onto the mucous membranes of the cervix with an applicator. Cervidil is a wafer-like insert thatâs positioned in the top of the vagina. Once the gel or insert is in place, it slowly releases prostaglandins into the nearby tissues. Prepidil and Cervidil usually take six to 12 hours to take full effect, after which the cervix is re-evaluated to see if labor can be induced. If your cervix still hasnât ripened, your doctor may give you another dose of medication.
Turbines have a typical lifespan of around 20-25 years, during which time some maintenance may be required. Should a developer wish to extend the lifetime of the development, then a new planning application would be required.
View full size image. One of the fastest-growing sources of energy in the world, wind turbines generate electricity without emitting greenhouse gases into the environment (unlike fossil fuels). These modern-day windmills convert mechanical energy from the wind into electrical power. Most wind turbines have three main parts: the tower (the long stem that connects to the ground); the blades, which connect to a central hub (the rotor); and the nacelle (a box behind the blades that contains the generator).
