   Författare :Tom W. Adawi; Jon Ogborn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; M-theory; p-branes; supersymmetry; duality; heat and temperature; phenomenography; context; Physics Education Research; Fysik; Fysikens didaktik; Physics; Fysik; Materiefysik; Physics of Matter; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Sammanfattning : This thesis is concerned with research in both physics and physics education, and is divided into two parts.Part IString theory has been the leading candidate over the past few years for a theory that unifies all the fundamental forces of nature. LÄS MER

3. 2. Moralen, barnet eller vetenskapen? : En studie av tradition och förändring i lärarutbildningen

   Författare :Agneta Linné; Lars-Magnus Engström; Donald Broady; Ulf P. Lundgren; Daniel Kallós; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teacher education; educational sociology; educational history; educational theories; social theories; curriculum research; curriculum theory; theories of cultural reproduction; Education; Pedagogik;

   Sammanfattning : Tradition and change in compulsory school teacher education are studied historically, using the theoretical framework of curriculum theory and theory of cultural reproduction. The concepts of classification and framing are used as analytic devices. LÄS MER

4. 3. Phenomenology of Higgs Bosons Beyond the Standard Model

   Författare :Glenn Wouda; Rikard Enberg; Gunnar Ingelman; Johan Rathsman; Rui Santos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle physics; The Standard Model; Higgs bosons; Higgs mechanism; Beyond the Standard Model; Two Higgs Doublet Models; Charged Higgs boson; Higgs decays; Supersymmetry; Renormalization; LHC; Collider constraints; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : After a long history of searches, a Higgs boson H was discovered by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in 2012. Its properties fit well the ones predicted by the Standard Model (SM) of particle physics. However, the SM can not explain other established properties of Nature, such as the existence of Dark Matter. LÄS MER

5. 4. Metal film growth on weakly-interacting substrates : Stochastic simulations and analytical modelling

   Författare :Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Pär Olsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thin films are nanoscale layers of material, with exotic properties useful in diverse areas, ranging from biomedicine to nanoelectronics and surface protection. Film properties are not only determined by their chemical composition, but also by their microstructure and roughness, features that depend crucially on the growth process due to the inherent out-of equilibrium nature of the film deposition techniques.

7. 5. Proton-Coupled Electron Transfer from Hydrogen-Bonded Phenols

   Författare :Tania Irebo; Leif Hammarström; James M. Mayer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proton-coupled electron transfer; phenol oxidation; hydrogen bonds; artificial photosynthesis; promoting vibrations; proton transfer; laser flash-quench; transient absorption.; Physical chemistry; Fysikalisk kemi; Fysikalisk kemi; Physical Chemistry;

   Sammanfattning : Proton-coupled electron transfer (PCET) is one of the elementary reactions occurring in many chemical and biological systems, such as photosystem II where the oxidation of tyrosine (TyrZ) is coupled to deprotonation of the phenolic proton. This reaction is here modelled by the oxidation of a phenol covalently linked to a Ru(bpy)32+-moitey, which is photo-oxidized by a laser flash-quench method. LÄS MER
