The ratio of effectual emitter area to base area of a FFJ is 2-3 times greater than a usual transistor and the output power-impedance product is 5-10 times greater.

The gain of the PMT, that is the ratio of anode output current to the photoelectric current from the photocathode, is directly related to the supply voltage.

Methods: Using mon-vessel screen method of thalassemia and relative value of G6PD detect thalassemia and G6PD deficiency for man and woman of detection of before marriage in 4268 duplet.
