  1. 1. Some Fundamental Aspects Concerning Secondary Steelmaking

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jimmy Gran; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : The present thesis deals with some aspects concerning secondary metallurgy of steel where there is little or very inconsistent information in the literature. More specifically, it is devoted to the studies on high temperature phase equilibria in the Al2O3-CaO-MgO-SiO2 system, the formation of ladle glaze and the thermodynamics of magnesium in liquid iron.

  4. 4. Synthesis and Studies of NADH Models: Stereoselective Reductions and Host-Guest Properties

    Detta är en avhandling från Chalmers University of Technology

    Författare :Ulrik Gran; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oorganisk kemi; Inorganic chemistry; NADH model; macrocyclic; synthesis; stereoselective reductions; host-guest complex; reducing agent;

    Sammanfattning : The aim of the project has been to synthesise macrocyclic NADH models and to study them as reducing agents and hosts. Three types of macrocyclic NADH models have been synthesised. They consist of the same subunits; a chiral unit, a nicotinamide unit and an aromatic spacer. LÄS MER

  5. 5. The Quest for M-theory

    Detta är en avhandling från Chalmers University of Technology

    Författare :Ulf Gran; Chalmers tekniska högskola.; Chalmers University of Technology.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; M-theory; supergravity; superspace; string theory; gauge symmetry; supersymmetry; duality; p-branes; D-branes; solitons;

    Sammanfattning : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. LÄS MER
