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.
Symptoms of eclampsia include those of preeclampsia along with the development of seizures. When seizures occur, they are most often preceded by neurologic symptoms like headache and vision disturbances. Women with severe preeclampsia may have a reduced platelet count (below 100,000).ther symptoms and signs that can occur with severe preeclampsia are dizziness, headaches, nausea, vomiting, abdominal pain, vision changes, changes in reflexes, altered mental state, fluid in the lungs (pulmonary edema), and a decrease in urine output.
