Various halvings and doublings of 44.1 kHz are used – the lower rates 11.025 kHz and 22.05 kHz are found in WAV files, and are suitable for low-bandwidth applications, while the higher rates of 88.2 kHz and 176.4 kHz are used in mastering and in DVD-Audio – the higher rates are useful both for the usual reason of providing additional ...
The sampling frequency or sampling rate, , is the average number of samples obtained in one second, thus = /, with the unit samples per second, sometimes referred to as hertz, for example 48 kHz is 48,000 samples per second.
If the ratio of the two sample rates is (or can be approximated by) [A] [4] a fixed rational number L/M: generate an intermediate signal by inserting L − 1 zeros between each of the original samples. Low-pass filter this signal at half of the lower of the two rates. Select every M-th sample from the filtered output, to obtain the result. [5]
The DVD format uses the 48 kHz sampling rate, and its doublings. In digital audio, 48,000 Hz (also represented as 48 kHz or DVD Quality) is a common sampling rate. It has become the standard for professional audio and video. 48 kHz is evenly divisible by 24, a common frame rate for media, such as film, unlike 44.1 kHz. [i]
In South Africa, some universities follow a model based on the British system. Thus, at the University of Cape Town and the University of South Africa (UNISA), the percentages are calibrated as follows: a first-class pass is given for 75% and above, a second (division one) for 70–74%, a second (division two) for 60–69%, and a third for 50–59%.
A class-based affirmative action policy was incorporated into the admission practices of the four most selective universities in Israel during the early to mid-2000s. In evaluating the eligibility of applicants, neither their financial status nor their national or ethnic origins are considered; the emphasis is on structural disadvantages ...

[86] [88] These crime rates are high relative to other American cities, but St. Louis index crime rates have declined almost every year since the peak in 1993 (16,648), to the 2014 level of 7,931 (which is the sum of violent crimes and property crimes) per 100,000. In 2015, the index crime rate reversed the 2005–2014 decline to a level of 8,204.
