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.
Doctors may treat preterm labor with 48 hours of mag, hoping to buy enough time to complete a course of steroids to help the baby's lungs develop. Prevent seizures from eclampsia: Preeclampsia is a common complication of pregnancy that causes high blood pressure and protein in the urine.
