  2. 1. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles

    Author : Jonas Granestrand; Lars Pettersson; Todd J. Toops; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Oxidation catalyst; heavy-duty vehicles; catalyst deactivation; biodiesel; NAP-XPS; XANES; Phosphorus; alkali metals; Pt Pd Al2O3; Chemical Engineering; Kemiteknik;

    Abstract : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.

  4. 2. Quantitative Muscle Composition Analysis Using Magnetic Resonance Imaging

    Author : Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

    Abstract : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. READ MORE

  5. 3. Quiescent regimes in cosmology

    Author : Hans Oude Groeniger; Hans Ringström; Mattias Dahl; Todd Oliynyk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quiescence; Bianchi spacetimes; big bang formation; G2 cosmology; Wainwright-Hsu variables; Klein-Gordon equation; Matematik; Mathematics;

    Abstract : This thesis is about cosmological solutions to Einstein’s equations of general relativity, in particular spacetimes whose mean curvature diverges. Moreover, we consider anisotropic spacetimes with big bang singularities. In this setting the singularity is expected to generically be oscillatory if no matter is present. READ MORE

  6. 4. Molecular Motion in Frustrated Lewis Pair Chemistry: insights from modelling

    Author : Maoping Pu; Timofei Privalov; Todd Martinez; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 capture; hydrogen activation; molecular motion; ab initio molecular dynamics; frustrated Lewis pair; quantum chemical modelling; reaction mechanism; Organic Chemistry; organisk kemi;

    Abstract : Mechanisms of reactions of the frustrated Lewis pairs (FLPs) with carbon dioxide (CO2) and hydrogen (H2) are studied by using quantum chemical modelling. FLPs are relatively novel chemical systems in which steric effects prevent a Lewis base (LB) from donating its electron pair to a Lewis acid (LA). READ MORE

  7. 5. Beyond Education and Society : On the Political Life of Education for Sustainable Development

    Author : Stefan L. Bengtsson; Leif O. Östman; David O. Kronlid; Karin Hjälmeskog; Thomas Popkewitz; Sharon Todd; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; ESD; environmental education; Education for Sustainable Development; sustainability; policy; education policy; globalisation; globalization; hegemony; discourse; space; antagonism; political; politics; temporality; beyond; mutation; rhizome; rhizomic; play; Laclau; utbildning; UHU; miljöundervisning; utbildning för hållbar utveckling; hållbar utvecking; politik; policy; utbildningspolicy; globalisering; hegemoni; diskurs; antagonism; temporalitet; mutation; rhizome; spel; Laclau; Curriculum Studies; Didaktik;

    Abstract : The objective of this dissertation is to develop a theoretical and analytical framework for understanding the political in education from a social and global perspective. With this objective in mind, it employs an empirical engagement and theoretical reflection on how this political can be seen to emerge in policy making on Education for Sustainable Development (ESD).
