Fire and Materials, EarlyView.ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...
