1 Most cases of malaria and most of the deaths caused by malaria occur in Africa.  Although most cases of malaria are caused by Plasmodium falciparum or P. vivax, P. falciparum accounts for almost all of the deaths caused by malaria.
For Echocardiography, color Doppler frame rates should be kept 17 Hz or above and preferably in the 20-30 Hz range. Every ultrasound machine has a numeric display of the current frame rate, which can range from less than 10 Hz to more than 60 Hz. Above: Image data area with FPS (Frames Per Second) and other adjustments.
For a LCD/LED display, this means a refresh rate of either 120Hz or 240Hz. 24 frames fits exactly in 120 frames per second. 120/24=5, so each frame is displayed 5 times. There is no need for the 3:2 pulldown technique, each frame has exactly the same time on the screen.
