Marine submersible buoy systems hold significant value as critical equipment in marine science research. This study examines a system that includes an anchor block, mooring line, battery compartment, power supply cable, and buoy. The anchor-last deployment method is conventional strategy for deploying systems. Initially, the other components are positioned on sea surface, followed by of block f...

PURPOSE To evaluate the load to failure and the mode of failure of a novel suture anchor construct that does not require knots (the "twist-lock" construct) and to compare it with a standard suture anchor construct (Corkscrew; Arthrex, Naples, FL). TYPE OF STUDY Biomechanical single-pull load-to-failure study comparing the twist-lock construct to the Corkscrew suture anchor construct. METHOD...

Nacrtak This paper deals with accidents in the period 1998 – 2008 reported during harvesting operations in ÖBf AG, Austria’s largest forest enterprise, with a focus on cable yarding. In total 1888 accidents were recorded with 8.7% of these associated with cable yarding activities. The overall accident rate amounted to 36 incidents per million cubic meter extracted by cable yarder. There was a c...

As the largest filled-aperture radio telescope in world, China's five-hundred-meter diameter Aperture Spherical Radio Telescope (FAST) is supported using a unique ultra-high fatigue stress cable net structure to enable flexible deformation of reflector. each supporting cables required be capable bearing an (up approximately 500 MPa), new type anchor specially designed this paper provide high pr...

Taking a super large deep foundation pit project as an example, the horizontal displacement of crown beam and driveway, surface settlement, axial force anchor cable, underground water level in construction process are dynamically monitored analyzed. The excavation deformation rule influence on surrounding buildings results show that, with pit, driveway incline towards direction eventually tend ...

During the pore-forming stage of floor heave treatment, phenomenon gravel sediment accumulation in bottom hole often occurs, which causes great difficulties normal installation anchor cable. Based on this observation, a new cable method was proposed, involves installing drill bit at front end to assist its drilling. With help an drilling test bench, influence bit, motion parameters, and environ...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

Cable tensile forces in winch-assist harvesting have been investigated order to assess the safety concerns of technology. However, literature is lacking, particularly regards impact winch design. In this study, a Summit Winch Assist tethering feller-director on ground slopes up 77% was monitored for four days. The cable were simultaneously recorded at and anchor machine frequency 100 Hz.
