We are in the world of ‘Game of Thrones’. It is Season 1, the episode where Jorah Mormont explains to Daenerys that the Dothraki have a right to rape and pillage the flock of lambs-people they have just conquered. Daenerys looks upon the unfolding horror mortified, and as she takes in the pain, spurs to action in what is one of the first instances of her exercising her recently acquired power: that of Queen, or to be more precise, Khaleesi. She peels a Dothraki warrior off a woman and claims her as a handmaiden.

In this chapter, I advocate applying Homi Bhabha’s concept of the “unhome” to teaching Nella Larsen’s novel Quicksand in a study abroad course to Copenhagen, Denmark. This chapter connects Helga Crane’s biracial identity to her feeling of “unhome” as the catalyst for her journey from the south, to Chicago, to Harlem, to Copenhagen, and ultimately the United States again. Finally, the text exposes how travel does not fully offer solutions for characters struggling with racism in the United States and foreshadows the difficulties later writers experience trying to navigate America’s complex racial milieu.

Geological risk as the qualitative or quantitative measure of geological hazard or a complex of hazards established for a certain object in the form of possible absolute or relative economic losses (damage) is the function of affecting hazard(s) value and the vulnerability of engineering structure. The georisk analysis in urban areas is usually aimed at the existing urban infrastructure, whereas assessment of geological risk for future construction appears to be a new approach in risk analysis. In urban areas, the risk of probable losses for a particular engineering structure in the course of its construction and operation may be comparatively analyzed for different types of engineering geological conditions distinguished in the area proceeding from the assessment of geological hazards that affect the engineering structures, since the vulnerability of engineering structure to these geological hazards is taken as constant in this case. Upon this approach, the qualitative characteristics of possible damage from geological hazards within the area with engineering geological conditions of a certain type serve as the risk index. According to the developed procedure, the map of geological risk upon the construction and operation of shallow (20 m deep) tunnels was compiled to a scale of 1:100,000 for the territory of Moscow. The possible damage was assessed proceeding from the analysis of such hazards as groundwater and quicksand outburst in the construction pit, suffusion, and karst-suffosion processes affecting the building structures. Very high geological risk arises upon the construction and running tunnels in water-saturated sandy ground, whereas the low risk is identified for the tunnels running in low-permeable Jurassic clay.

This paper proposes a numerical method to simulate the seepage failure of sandy materials, known as sand boils or quicksand. The sand is largely deformed and the particles rapidly migrate with the seepage water after the seepage failure. In order to deal with the large deformation and the migration of the sand particles, an Eulerian formulation is applied to the governing equations, i.e., the equations for the conservation of mass and momentum of seepage water and sand, which yields a system of hyperbolic partial differential equations. To achieve stable and accurate numerical solutions for the hyperbolic system, the Central Weighted Essentially Non-Oscillatory (CWENO) method is employed herein. The numerical simulation of the 1D seepage failure of sand, induced by an upward seepage flow, is conducted and the computation is compared with analytical solutions. The results show that the proposed method can reproduce the behavior of sand particles and seepage water during seepage failure.
