A powder composition containing at least one fat-soluble vitamin dispersed in a matrix of a natural polysaccharide gum or a mixture of gums having an emulsifying capacity andor a protein or a mixture of proteins having an emulsifying capacity. A first speed of sound for the fluid flowing through the pipeline is measured for an ultrasonic signal that would reflect from stratified flow, if present. A main beam M incident area is divided with a boundary defined by the first parting line. A sense amplifier corresponds to a plurality of the bit lines. A radiation dose distribution is adapted on the basis of shape and position variations of the organs of interest determined from a comparison of a first image and a second image which were taken at different points of time during the radiation treatment process. The strained silicon layer increases charge transfer efficiency, decreases image lag, and improves blue response in imaging devices.
