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.
A diagnosis of preeclampsia early in a womanâs pregnancy can be tricky. The baby needs time to grow inside its mother, but both the mother and the baby need to avoid any serious complications. In this case, your doctor may prescribe magnesium sulfate. Magnesium sulfate therapy is used to prevent seizures in women with preeclampsia. It can also help prolong a pregnancy for up to two days. This allows drugs that speed up your babyâs lung development to take effect.
