While schools have been assigned the role of introducing students to our current democratic systems, many have highlighted the paradox of teaching democracy in an undemocratic context (e.g.Biesta, 2007).Alternative models of schools that operate democratically such as free schools (democratic schools WINTERGREEN TOOTHPASTE in which students and tea
The bridge horizontal swivel system generally adopts a symmetrical structure and uses a spherical hinge structure that can adjust the rotation to complete rotation construction.Because of the complexity of railway lines under bridges, some asymmetrical horizontal swivel systems have been increasingly applied in practical engineering in recent years
Abstract Background The appropriate degree of constraint in knee prosthetic revision is unknown, necessitating the use of the lowest possible constraint.This study aimed to compare the long-term clinical and survival results of revision with rotation hinge knee (RHK) VS constrained condylar constrained knee (CCK) implants.Methods Overall, 117 revis
