Mesophase pitch-based carbon fibres have excellent resistance to plastic deformation (up to 840 GPa); however, they have very low strain to failure (0.3) and are considered brittle.Hence, the development of pitch fibre precursors able to be plastically deformed without fracture is important.We have previously, successfully developed pitch-based pre
Elbow Brace In this article the transition from literary realism (Balzac, George Eliot, Verga) is described as a shift from mimesis to constructivism.It is indicated how the realist confidence in the ability of the writer to represent reality as such yields to a modernist skepticism which recognises the contingent character of all fictional constru
ObjectiveThis study aimed to demonstrate and characterize a rare cervical spondylotic myelopathy (CSM) with sciatica-like pain as the main clinical manifestation through case presentation and systematic review.MethodsFour cases of CSM with sciatica-like pain as the main clinical manifestation were retrospectively studied.A systematic review of elec
The deep roadway with broken surrounding rock has problems such as insufficient strength of surrounding rock, serious floor heave, etc.It is urgent to strengthen the surrounding rock with effective support means.With the help tension of COMSOL numerical simulation software, the paper constructs the grouting diffusion model of roadway coupling grout
