The behavior of cold-formed steel and Belian hardwood self-tapping screw connections [PDF]

, 2022
Cold-formed steel has been widely used to retrofit and restore buildings, especially timber buildings. This is because the material is readily available, flexible, and lightweight.

Axial Performance of Self-tapping Screws in Mass Timber Products Under Moisture Content Variation [PDF]

, 2022
Self-tapping screws (STS) are widely used in wood-to-wood and wood-to-steel connections in timber structures. The premature failure of STS during the construction phase has been recently reported by structural engineers and contractors of several mass ...

Abduction and Deduction in Dynamical Cognitive Science

Topics in Cognitive Science, EarlyView., 2023
Abstract This paper reviews the recent history of a subset of research in dynamical cognitive science, in particular that subset that allies itself with the sciences of complexity and casts cognitive systems as interaction dominant, noncomputational, and nonmodular. I look at this history in the light of C.S.

Experimental and numerical analysis of the unreinforced and reinforced notched timber beam by a screw

Vietnam Journal of Science, Technology and Engineering, 2018
Timber is highly anisotropic. It behaves differently in diverse directions. Tension and compression perpendicular to the grain present a low strength with respect to the ones parallel to the grain.

Geometry of anchoring miniscrew in the lateral palate that support a tissue bone borne maxillary expander affects neighboring root damage

Scientific Reports, 2021
Anchoring miniscrews used for a tissue bone borne maxillary expander (C-expander) can fail if they contact tooth roots or perforate the maxillary sinus. Cone beam computed tomography images were reviewed retrospectively to evaluate the geometric factors ...
