IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2002
We present a drilling method that is based on the phenomenon of local hot spot generation by near-field microwave radiation. The microwave drill is implemented by a coaxial near-field radiator fed by a conventional microwave source. The near-field radiator induces the microwave energy into a small volume in the drilled material under its surface, and a

This chapter demonstrates how the provincial realist novel incorporated exhaustion as a temporal structure to depict the new horizons of human life under extractivism. Provincial realism's longstanding reliance on the marriage plot and the inheritance plot, on providing closure via social reproduction, transforms against the backdrop of extractivism to
