  2. 1. Complexity Theory and Physics Education Research : The Case of Student Retention in Physics and Related Degree Programmes

    Author : Jonas Forsman; Cedric Linder; Ismo Koponen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics Education Research; Complexity Theory; Student Retention; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This thesis explores the use of complexity theory in Physics Education Research as a way to examine the issue of student retention (a university’s ability to retain its students). University physics education is viewed through the concepts of nestedness and networked interactions. READ MORE

  4. 2. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

    Author : Giorgos Papaspiropoulos; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

    Abstract : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. READ MORE

  5. 3. Constraining the top-Z coupling using the (ttWj)EW process with the ATLAS experiment : A search for physics beyond the Standard Model

    Author : Nabila Ahlgren; Jörgen Sjölin; Robert Schöfbeck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; ATLAS; top physics; fysik; Physics;

    Abstract : The Standard Model (SM) of particle physics, having been confirmed by numerous experiments, is one of the most successful theories in physics. It describes all known elementary particles and their interactions through the electromagnetic, strong and weak force. READ MORE

  6. 4. Searches for exotic stable massive particles with the ATLAS experiment

    Author : Christian Ohm; David Milstead; Torbjörn Moa; Albert Roeck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; squark; gluino; stable massive particles; long-lived particles; physics analysis; search analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to  3×1033 cm-2s-1 . READ MORE

  7. 5. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    Author : Marie Wegdén; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE
