ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

Abstract Wood under thermo-mechanical densification behaves differently depending on the cross-sectional growth ring orientation (GRO) relative to direction of compression. This influences degree cell damage, but also shape-memory effects occurring when compression load is released (spring-back) and timber re-moistened (set-recovery). To study how GRO effects, Scots pine specimens were separate...
