Decay of bow thruster induced near-bed flow velocities at a vertical quay wall: A field measurement

During berthing operations vessels use their bow thruster(s) to improve their manoeuvrability, making them less dependent on the assistance of tugboats. The jet from a bow thruster reflects on the quay wall. It is directed towards the bottom where it reflects, causing high flow velocities over the bed. This may scour the nearby bed when it is...

Heat induced attachment and detachment of delicate tissues: Towards a new micro tissue gripper

Indirect Heat Induced Attachment and Detachment (HIAD) is a promising concept for gripping delicate tissues in ophthalmic surgery. However, the optimal settings of attaching to and detaching from delicate tissues are unknown. This study presents the effects of the instrument heating properties and initial contact force on the adhesion force,...
