Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.

In theater, the tableau takes on an entirely different dimension. It serves as a staging technique where actors create a living picture, freezing in dynamic poses to convey emotions and pivotal moments in the narrative. This technique has been particularly prominent in classical theater, where a single scene can encapsulate the essence of a play. The tableau vivant, or living picture, engages the audience's imagination, compelling them to derive meaning from the stillness and the relationships portrayed among the characters. This method not only enhances the visual experience of the performance but also deepens the audience's emotional engagement with the story.

Les barres de forage, ou drill rods en anglais, jouent un rôle crucial dans l'industrie de l'exploration minière et pétrolière.
