Abstract Open-loop borehole heat Novelty Items - Picture Frames exchanger (OBHE) is a single well geothermal heat exchanger with an open-loop structure that can realize the geothermal energy extraction without mining the geothermal water.In this paper, a sandbox experiment is designed to simulate the convective heat transfer process in the reservoi
The objective of this study was to test the influence of selected base metals, which act as oxide formers, on the metal-ceramic bond of dental veneer systems.Using ion implantation techniques, ions of Al, In and Cu were introduced into near-surface layers of a noble metal alloy containing no base metals.A noble metal alloy with base metals added fo
The application of surgical navigation in oral and maxillo-facial surgery has been increasing over time.In fact, computer-assisted surgery provides real-time, precise, and accurate position and guidance during surgery.The purpose of our work is to introduce the evolution of surgical navigation in recent decades, describe some technical aspects of t
