  2. 1. External Water Condensation and Angular Solar Absorptance : Theoretical Analysis and Practical Experience of Modern Windows

    Author : Anna Werner; Arne Roos; Claes-Göran Granqvist; Svend Svendsen; Uppsala universitet; []
    Keywords : Engineering physics; Windows; External condensation; Radiative cooling; Optical properties; Coated glass; External condensation; Radiant cooling; Teknisk fysik;

    Abstract : Part I of this thesis is a theoretical background to parts II and III. Part II treats the phenomenon of decreased visibility through a glazing due to external water condensation, dew, on the external surface. Some simulations are presented where it is shown that under certain circumstances condensation can be expected. READ MORE

  4. 2. Non-Perturbative Quantum Field Theory in Extreme Environments

    Author : Per Liljenberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pair production; Bose-Einstein condensation; functional representation; Schwinger model; external field; boson stars; temperature; magnetisation;

    Abstract : The aim of this thesis is to describe some physical systems which can be treated by non-perturbative methods in quantum field theory. In the thesis we study systems described by quadratic Hamiltonians, possibly extended with an external electromagnetic field and/or with a thermal heat bath. READ MORE

  5. 3. Hygroscopic Growth of Atmospheric Aerosol Particles and Its Relation to Nucleation Scavenging in Clouds

    Author : Birgitta Svenningsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol formation; atmospheric aerosols; hygroscopic growth; nucleation scavenging; cloud; water activity; external mixing; tandem differential mobility analyser; Kärnfysik; cloud condensation nuclei spectra; Nuclear physics; TDMA; Fysicumarkivet A:1997:Svenningsson; inorganic salts;

    Abstract : Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. READ MORE

  6. 4. Hot and Dense Gauge Theories with External Fields

    Author : David Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the introductory part of this thesis, I briefly review quantum statistichal mechanics; quantum field theory with external fields; the real and imaginary time formalisms in thermal field theory; and the hard thermal loop resummation. In the second part, consisting of here reprinted research articles, we apply this to quantum electrodynamics and quantum chromodynamics with a background (chromo-) magnetic field in the presence of a heat and charge reservoir.

  7. 5. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass

    Author : Jenny Rissler; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cloud condensation nuclei; H-TDMA; CCN; hygroscopic growth; Teknik; internal and external mixture; CLAIRE; SMOCC; Physics; Fysik; Environmental chemistry; Technological sciences; Miljökemi; tandem differential mobility analyzer; slash and burn; Amazon; Biomass burning; combustion; Fysicumarkivet A:2005:Rissler;

    Abstract : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.
