BACKGROUND The purpose of this study was to investigate the relative contributions of two proposed mechanisms, strength imbalance and impaired longitudinal muscle growth, to osseous and postural deformity in a rat model of brachial plexus birth palsy (BPBP). METHODS Thirty-two Sprague-Dawley rat pups were divided into four groups on the basis of surgical interventions to induce a strength imb...
Continuous tunneling using a tunnel-boring machine is very popular method when it comes to the construction of large tunnel projects. The use precast reinforced concrete elements, called tubbings, highly economical way secure post excavation. Unfortunately, loss load-bearing capacity has been observed in past joints between tubbings. Reasons for that are among others required reduction cross se...
