Oceanic lithosphere is continuously formed at a constant rate at the mid-ocean ridges 1 0 = 0. Thus at x = 0 the temperature is the Heaviside step function. Finally, we assume the system is at a quasi-steady state, so that the temperature distribution is constant in time, i.e. T=T(x,z).
Because preeclampsia can prevent proper blood flow to the placenta, babies may be born prematurely and can suffer from later conditions such as learning disabilities, epilepsy and hearing and vision problems.
Nonsteroidal anti-inflammatory medications, more commonly known as NSAIDS, can slow or prevent preterm labor by blocking production of prostaglandins, which help cause uterine contractions. To stop preterm labor, the NSAID indomethacin is given intravenously, by mouth or via rectal suppository.
