An Investigation of Pull-Out Force of Semi-Buried Lotus Roots after Hydraulic Scouring

open access: yesAgriculture, 2021
Hydraulic scouring is the most effective approach to harvest lotus roots, but its application is largely restricted by the low harvesting rate. After hydraulic scouring, some mature lotus roots are still partially buried in the soil.

Study of Nail Group Efficiency on Sandy Soil Using Large Scale Pull-out Box [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2022
The present study aims at investigating the pull-out resistance efficiency of single and double nails. In sandy soils, where the distance between nails is less than the minimum required distance, the pull-out resistance is reduced.

A study on the use of the Osstell apparatus to evaluate pedicle screw stability: An in-vitro study using micro-CT. [PDF]

open access: yesPLoS ONE, 2018
Pull-out force and insertion torque have not been generally used as intraoperative measures for the evaluation of pedicle screw stability because of their invasiveness.

Experimental and Analytical Study on Pull-out Force of Steel Fiber-Reinforced Concrete Blocks

open access: yesDiyala Journal of Engineering Sciences, 2022
Reinforcing bar bonding in concrete is essential for reinforcing bar anchoring and reinforced concrete cracking control. A pull out test of a reinforcing bar embedded in a concrete block is commonly used to determine it. When compared to plain concrete,
