Loc: Boston,Massachusetts U.S.A. I have a question on wedding traditions, I was hoping that you might enlighten me.. In Spain the wedding ring is put on the right hand while in the U.S it is on the left hand..
Doppler assessment of area by pressure half-time method ï§ The time required for the mitral diastolic pressure to fall by 50% ï§ Mitral valve area is calculated as: 220 â pressure half time (msec).
1 From the graph you can work out the time (half-life) it takes for half of the radioactive atoms to decay from the decrease in count rate. 2  e.g. in terms of time elapsed, count rate ==> we get. 3  0min, 400cpm ==> 10min, 200cpm ==> 20min, 100 cpm etc.  clearly showing the half-life is 10 minutes.
