Electrostatic interaction of microcapsules with guinea-pig polymorphonuclear leucocytes was investigated at different ionic strengths of the medium through measurements of the degree of phagocytosis by the cells of microcapsules. At any ionic strength, the interaction exhibited a maximum when the surface potential of microcapsules was equal to that of the(More)
When a color video system with highly accurate color reproduction is designed, a good measure is required for evaluating the image quality including the color reproduction. There are some degradation sources in a total imaging system from image acquisition to image reproduction. Color random noise is one of major degradations which is often added in image(More)
