Mid-term results of intra-articular calcaneal fractures treated with minimally invasive two-point distractor : Single center study with 6-year follow-up.

Background: Displaced intra-articular calcaneal fractures are a complication-ridden injury to treat and there are various treatment techniques to address this injury. The aim of this study was to evaluate the mid-term outcome of a percutaneous two-point distractor technique in patients with displaced intra-articular calcaneal fractures.

Methods: A retrospective data analysis of patients with intra-articular calcaneal fractures treated in a level 1 trauma center was conducted.

Comparing municipal progress in implementing temporary cycle lanes during the Covid-19 pandemic.

This study investigates whether the Covid-19 pandemic opened a policy window of opportunity for the implementation of temporary cycle lanes, and how German municipalities differed in their implementation progress. The Multiple Streams Framework is used to guide the data analysis and interpretation of the results. A survey of staff working in German municipalities is conducted.

Oxidative depolymerization of lignin in ionic liquids.

Beech lignin was oxidatively cleaved in ionic liquids to give phenols, unsaturated propylaromatics, and aromatic aldehydes. A multiparallel batch reactor system was used to screen different ionic liquids and metal catalysts. Mn(NO(3))(2) in 1-ethyl-3-methylimidazolium trifluoromethanesulfonate [EMIM][CF(3)SO(3)] proved to be the most effective reaction system.
