3) Critically damped: [math]x(t) = (A + Bt)e^{- \gamma t}[/math] This is the optimally damped case, where the damping coefficient is just large enough to completely quell the oscillations, so the oscillator returns to zero in the least amount of time possible. 4) Overdamped: [math]x(t) = Ae^{- \gamma_{1}t} + Be^{- \gamma_{2}t}[/math]
DEAR READER: A woman is considered to be in menopause once it has been one year since her last period. Once menopause begins, vaginal bleeding is not normal. Post-menopausal bleeding (PMB) can happen for many reasons. It may result from infection or injury. Non-cancerous growths such as polyps and fibroids can cause PMB. So can bleeding disorders or use of blood thinners.
For most women in their 30s, menstrual periods are highly predictable. With the onset of the menopausal transition in their 40s, women's menstrual periods can change dramatically. ANN ARBORâWomen going through menopause most likely think of it as the time for an end to predictable monthly periods.pecifically, the research found that it is not uncommon for women to have prolonged bleeding of 10 or more days, spotting for six or more days and/or heavy bleeding for three or more days during the transition.
