Biomechanical feasibility of semi-rigid stabilization and semi-rigid lumbar interbody fusion: a finite element study [PDF]
Background Semi-rigid lumbar fusion offers a compromise between pedicle screw-based rigid fixation and non-instrumented lumbar fusion. However, the use of semi-rigid interspinous stabilization (SIS) with interspinous spacer and ligamentoplasty and semi ...

Dual-functIon Semi-rigid thoraCoscOpy Versus semi-rigid thoracoscopy for the diagnosis of plEuRal diseases: protocol for a multicentre, open-label, randomised controlled trial in China (DISCOVER-I) [PDF]
Background Exudative pleural effusion often presents diagnostic challenges, with up to 25% of cases remaining undiagnosed after thoracentesis or closed pleural biopsy. Semi-rigid thoracoscopy is a widely used minimally invasive diagnostic method. However,

Design of non-linear semi-rigid steel frames with semi-rigid column bases
This article presents an analysis and design method for steel frames with semi-rigid connections and semirigid column bases. The analysis takes into account both the non-linear behaviour of beam-to-column connections and P-Δ effects of beam-column ...

STUDI TENTANG DIAFRAGMA KAKU DAN SEMI - KAKU PADA STRUKTUR GEDUNG DENGAN KETIDAKBERATURAN VERTIKAL
Umumnya para insinyur cenderung menganggap bahwa diafragma struktur bangunan adalah kaku, tetapi arsitek sering merencanakan bangunan yang ramping menyebabkan analisis diafragma kaku tidak tepat digunakan. Diafragma kaku dan semi-kaku berperilaku berbeda.
