SACs are those genes with expression up-regulated during leaf senescence. Class I SACs are expressed only during senescence (senescence-specific). Class II SAGs have a basal level of expression during early leaf development, but this level increases during senescence.
Which Sample Rate to use. 44.1 kHz. 44.1 kHz (44100 Hz) is the sampling rate of audio CDs giving a 20 kHz maximum frequency. 20 kHz is the highest frequency generally audible by humans, so making 44.1 kHz the logical choice for most audio material.
FLAC - sample rate, sample size, bit rate Hi, A beginner's question to FLAC-ripping: I've ripped my cd collection to FLAC in dBpoweramp. I've now come in doubt as to whether 'sample rate', 'sample size' and 'bit rate' are variables that has an impact on the audio quality. I can see that my music is ripped with: Sample rate: 44.1 kHz. Sample size: 16 bit.
