Influence of Biological Pretreatment of Wooden Dowels on Strength of Rotary Welded Joints
BioResources, 2023 Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin.

Enhancing spinal bone anchor pull-out resistance with an L-shaped anchor.
PLoS ONEThe success rate of spinal fusion surgery is mainly determined by the fixation strength of the spinal bone anchors. This study explores the use of an L-shaped spinal bone anchor that is intended to establish a macro-shape lock with the posterior cortical

Centrifugal Modeling of Enlarged Base Foundation Subjected to Pull-Out Force
Soils and Foundations, 1998 This paper presents the centrifuge modeling of a prototype pull-out test conducted on enlarged base foundation using undisturbed block samples so that prototype values could be possible to extrapolate from model results. Undisturbed block samples were directly procured in specially designed centrifuge model containers to avoid sample disturbance ...

Pulling a polymer out of a potential well and the mechanical unzipping of DNA
, 2000 Motivated by the experiments on DNA under torsion, we consider the problem of pulling a polymer out of a potential well by a force applied to one of its ends. If the force is less than a critical value, then the process is activated and has an activation

Switch on, switch off: stiction in nanoelectromechanical switches [PDF]
, 2013 We present a theoretical investigation of stiction in nanoscale electromechanical contact switches. We develop a mathematical model to describe the deflection of a cantilever beam in response to both electrostatic and van der Waals forces.
