Population Density Gradient and Rent Gradient
1982In Chapter 1 we considered the existence of location equilibrium conditions with respect to the environmental quality of each location, and in Chapter 2 we examined a model of the process of urbanization accompanied by environmental degradation. Both models make clear theoretically the motivation of individual behavior.

Density Gradient Ultracentrifugation Technique
2018As a general, non-destructive, and scalable separation method, DGUC has recently been demonstrated as an efficient way of sorting colloidal nanoparticles according to their differences in chemical, structural, size, or morphology. After the introduction of basic concepts of density gradient ultracentrifugation, for the practical applications, there are
