1. 1. Meson Properties in Partially Quenched Effective Field Theory

   Författare :Niclas Danielsson; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

   Sammanfattning : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. LÄS MER

3. 2. Some Aspects of Chirality: fermion masses and chiral p-forms

   Författare :Astri Kleppe; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; massive neutrinos; fermion masses; Mathematical and general theoretical physics; self-dual fields; democratic family mixing; quantum mechanics; classical mechanics; relativity; gravitation; thermodynamics; statistical physics; statistisk fysik; termodynamik; Elementary particle physics; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1997:Kleppe;

   Sammanfattning : This thesis deals with different types of chiral fields. The properties of fermion masses are investigated from different poits of view, both within the Standard Model and in extensions of the model. It is shown how mass matrix invariants are used to define the measurables of the quark mixing matrix as invariant functions of the mass matrices. LÄS MER

4. 3. Nonlinear Elasticity of Fiber Masses

   Författare :Mårten Alkhagen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The mechanical properties of fiber masses are important in many fields of engineering such as upholstery, paper making, and composite manufacturing, and a fair amount of work has gone into analyzing these properties. However, previous theories have been limited to simple deformations and a restrictive choice of deformation mechanism. LÄS MER

5. 4. Massans röst : Upplopp och gatubråk i Stockholm 1719–1848

   Författare :Mats Berglund; Lars Nilsson; Maria Sjöberg; Börje Harnesk; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; riots; street violence; pre-industrial era; stagnation; Stockholm; political culture; democratisation; urban history; newspapers; Södermalm Riot; Ebel tumult; killing of Axel von Fersen; Crusenstolpe Riots; March Revolt; History; Historia; History; historia;

   Sammanfattning : The thesis examines riots and street violence in Stockholm between 1719 and 1848. By studying open conflicts, the thesis explores changes in societal power structures which otherwise are hidden. LÄS MER

7. 5. Fractured Rock Masses as Equivalent Continua - A Numerical Study

   Författare :Ki-Bok Min; KTH; []
   Nyckelord :fractured rock masses; equivalent continuum; discrete fracture Network DFN ; Distinct Element Method DEM ; Finite Element Method FEM ; Nuclear Waste Disposal; Coupled Thermo-Hydro-Mechanical Processes;

   Sammanfattning : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.
