A Tietze Transformation Program
A Reidemeister-Schreier program which yields a presentation of a subgroup H of finite index in a finitely presented group G is described in [3J. The program has two stages; first, Schreier generators and Reidemeister relators for H are computed, then the resulting presentation is simplified by eliminating redundant generators and by using a substring searching technique. The Tietze transformati...
متن کاملOssicular malposition in Larsen syndrome: a case report
Larsen syndrome is a rare condition that causes multiple large joint dislocations and characteristic flattened facies. We present a case of a patient with Larsen syndrome with a conductive hearing loss due to ossicular malposition/dislocation. We discuss the aetiopathogenesis of hearing loss in Larsen syndrome.
متن کاملBudd-Chiari Syndrome Caused by TIPS Malposition: A Case Report
Budd-Chiari syndrome refers to hepatic pathology secondary to diminished venous outflow, most commonly associated with venothrombotic disease. Clinically, patients with Budd-Chiari present with hepatomegaly, ascites, abdominal distension, and pain. On imaging, Budd-Chiari syndrome is hallmarked by occluded IVC and or hepatic veins, caudate lobe enlargement, heterogeneous liver enhancement, intr...
متن کاملPresentations and Tietze transformations of C*-algebras
In this work, I develop a new view of presentation theory for C*-algebras, both unital and nonunital, heavily grounded in classical notions from algebra. In particular, I introduce Tietze transformations for these presentations, which lead to a transformation theorem analogous to Tietze’s 1908 result in group theory.
متن کاملIntrapleural central venous catheter malposition.
Percutaneous insertion of central venous catheter (CVC) is a valuable procedure in managing critically ill patients. However, placement of CVC is not without its complications. The author reports a case in which a CVC was inserted into the right pleural cavity which was not detected by the usual clinical methods of confirming catheter placement and an antero-posterior (A-P) chest x-ray.
