Exhaust gas recirculation (EGR) sweeps were performed on ethanol partially premixed combustion (PPC) to show different emission and efficiency trends as compared with diesel PPC. The sweeps showed that when the EGR rate is increased, the efficiency does not diminish, HC trace is flat, and CO is low even with 45% of EGR. NOx exponentially decreases by increasing EGR while soot levels are nearly zer

I artikeln analyseras Thomas Hobbes frihetsbegrepp i relation till lag, rätt och det politiska tillståndets artificiella karaktär i avsikt att förstå hur Hobbes kan förena politisk absolutism med medborgarnas villkorade rätt att vara olydiga.

I religionernas värld har man alltid varit medveten om vilken betydelse ljud och tystnad har för vårt välbefinnande. Ibland framhävs tystnaden; i andra fall kan det röra sig om det monotona ljude av exempelvis en upprepad bön. Sådana övningar blir föremål för en psykologisk kommentar.

PURPOSE: A straight thoracic stent graft often complies poorly with the curvature of the aortic arch. We have previously reported an in vitro model of a modified stent graft that can be bent in situ after deployment to improve conformance to the aortic arch. We now report the first clinical experience with this technique in three consecutive patients. METHODS: Between September 2007 and August 200

The art of living and the art of eating: Professor Linnaeus recommends. By Gunnar Broberg. As professor of medicine, Linnaeus taught dietetics. He followed the pattern outlined by Galen and Regimen salernitatis, adding an extensive material originating from general cultural history and his own experience.Early in his life he wrote Diaeta naturalis, a collection of rules focusing the blessings of n

The Swedish inventor Christopher Polhem had an idea of a universal language which occupied him for decades, i.e. a perfect language which can be spoken and understood by everyone, by the educated and non educated alike, and no matter where they come from. Polhem did a large number of sketches for such a universal language, among others a manuscript concerning a lunar language, which was completely

The implementation of circular initiatives requires certain capabilities and knowledge that traditional business models often lack, requiring new perspectives and external collaborations. This paper explores the competency needs and partnership dynamics of established companies collaborating for business model innovation for circularity through a case study of a gap exploiter business model, a com

Sammanfattningsvis kan Självbestämmandeteorin (SDT) tillämpas av lärare för att stärka elevers motivation och välbefinnande. Däremot är det inte säkert att alla elever därigenom kommer att höja sin inre motivation eller sina studieresultat. Vissa elever är helt ointresserade av vissa ämnen och i avsaknad av motivation krävs mer än att tillämpa SDT. Vidare kan inte enbart ett förändrat klassrumskli

This chapter gives an overview of key actions by the activist group Gender Relations in New Music, which advocates for increased gender equality and intersectional diversification in contemporary classical music (CCM).
