Rachel Fuchs, of Arizona State University, writes that women who committed infanticide in the nineteenth century "were generally young, single domestic servants... alone and lacking family support, filled with shame, afraid to dishonor themselves and their families, and abandoned by their lovers".
Hundreds of canes — the elegant walking sticks of Victorian ladies and gentlemen, more fashion accessory than practical support — fill the window and line the walls of Michael German Antiques, tucked in the crook of a street in Kensington.
The steel pipe support filled with concrete is made of steel pipes and concrete.

New steel support types developed in recent years are the steel pipe support filled with concrete, the steel support with active setting force, and so on.
In view of the above-stated advantages of the steel pipe support filled with concrete, Chinese researchers developed the high strength steel pipe support filled with concrete, which is applicable to the roadways at depth or surrounded by soft rocks (Gao et al. 2010; Li et al. 2013), as shown in Fig. 9.
Applications in many underground coal mining areas showed that the steel pipe support filled with concrete can effectively control the severe deformation of roadways at depth, surrounded with soft rocks, and affected by mining disturbances.
The maximum bearing load of the steel pipe support filled with concrete (an enclosed form consisting of four segments, seamless steel pipes with dimensions of φ140 mm × 4.5 mm) is beyond 1,500 kN.
On one hand, the steel pipe filled with concrete can increase its stability; on the other hand, the pipe containment makes concrete in tri-directional compressive stress state, increases the concrete compressive strength and stiffness, and greatly improves the bearing capacity of the steel pipe support filled with concrete.
