The Thaumasia “rift”, Mars – Is It a Rift?

We describe the morphology of a large and complex graben structure in the western Thauma-sia region (the " Thaumasia graben " [1] or TG). We consider possible fault geometries, determine extension , and discuss shortly possible models for its origin. Background: Situated at the western border of the Thaumasia plateau, the TG is one of the most prominent fault-bounded structures on Mars. It is ~...

The Ecological Rift

The Midcontinent Rift System

One of the most prominent features on gravity and aeromagnetic maps of the United States is a series of major, generally linear anomalies that extend from central Kansas to Lake Superior and then turn southward into central Michigan (Figures 1, 2). This system of anomalies clearly reflects major geological features, and as such it must represent a very significant episode in the history of the ...

Continental rift

The azure-winged magpie (Cyanopica cyanus), has long presented a puzzle for biologists. The naturalist Alfred Wallace was one of the first to consider it. The puzzle lies in its extraordinary distribution. It exists in two distinct locations: Iberia and eastern Asia, 9,000 kilometres apart. Two alternative theories have been put forward to explain this curious distribution. The first proposes t...

A Separation, an Ideological Rift in the Iranian Society and Culture: Media, Discourse and Ideology

Media can be a good representation of dominant ideologies in society. The analysis of such discourse can shed light on the mental and social structures of people in society. Adopting van Dijk’s (1995) layout of discourse ideology and his (2000) practical and general outline of ideological analysis, this study analyzes the Iranian movie A Separation, the winner of the 84th An...
