ABTF = 10 [log.sub.10] [P.sub.specimen](f) - 10 [log.sub.10] [P.sub.reference](f) (1)
AIB, determined by integrating the curve of ABTF (Equation 2), expresses the average value of apparent backscattering in the frequency range of interest, while FSAB, the slope of the linear regression line obtained from the curve ABTF vs frequency, is the fraction of apparent backscattering corresponding to each frequency.
Prince Alwaleed, through ABTF
, has donated to many philanthropic projects globally, including a recent announcement of his readiness to donate over 100 housing units to be built at a total of SR5 million to victims of rundown slum areas in Cairo, a $235,282 donation to an Oxfam project - Increase Market Access for Women in Senegal, a donation of over $3 million to the Darfur region of Sudan and $356,500 to the Deworm the World Initiative.
