In this paper, we review the history, present state, and future of social epidemiology in South Africa. In “developing” nations such as South Africa, social epidemiology is cast in a new light owing to these countries’ distinctive political, economic, and social histories. South Africa is still grappling with the public health legacy of the colonial and apartheid eras while contending with new ...

Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
