The coupled diffusion equations recently proposed by Tokuyama for concentrated hard-sphere suspensions are numerically solved, starting from nonequilibrium initial configurations. The most important feature of those equations is that the self-diffusion coefficient DS(Φ) becomes zero at the...

In his seminal article on economic growth and income inequality, Kuznets (1955) advanced the hypothesis, that income inequality first increases and then decreases in relation to economic development. The authors explore the factors and forces underlying income inequality in Indonesia. (DÜI-Sen)
