  1. 1. Radiation and matter: how do they play with each other?

    Author : Davide Mancusi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy ions; models; transport codes; Boltzmann equation; Monte Carlo; radioprotection in space; radiotherapy; nuclear reactions;

    Abstract : The propagation of radiation is affected by the presence of matter; at the same time, the physicochemical properties of matter are modified by the passage of radiation. The interplay of radiation and matter is of crucial importance in many modern applications: accelerated heavy ions, in particular, can be used in radiotherapeutical treatments of some cancers; moreover, they are present in the space radiation environment and represent a serious threat to the health of spaceship crews and to the functionality of electronic equipment on board.

  2. 2. Some numerical and analytical methods for equations of wave propagation and kinetic theory

    Author : Eva Mossberg; Alexander Bobylev; Giovanni Russo; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wave propagation; finite difference metods high order methods; Landau-Fokker-Planck equation; Monte-Carlo simulations; Boltzmann equation; hard sphere model; eigenvalue problem; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

    Abstract : This thesis consists of two different parts, related to two different fields in mathematical physics: wave propagation and kinetic theory of gases. Various mathematical and computational problems for equations from these areas are treated. READ MORE

  3. 3. Biomedical and atmospheric applications of optical spectroscopy in scattering media

    Author : Johannes Swartling; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Turbid media; Tissue optics; Tissue optical properties; Multiple scattering; Radiative transfer; Diffusion equation; Monte Carlo method; Time-resolved spectroscopy; Atomic and molecular physics; Integrating spheres; Atom- och molekylärfysik; Fysicumarkivet A:2002:Swartling;

    Abstract : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. READ MORE

  4. 4. Statistical Mechanical Studies of Aqueous solutions and Biomolecular Systems

    Author : Fernando Luis Barroso Da Silva; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; highly charged macromolecules; dielectric discontinuity; dissociation constant; Tanford-Kirkwood model; protein mutation; electrostatic interactions; chemical potential; titration; biomolecules; computer simulations; radial distribution function; electrolyte solutions; continuum model.; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : This thesis is concerned with theoretical studies of aqueous solutions and biomolecular systems. Part of the present work is to understand equilibrium solvent and solute properties, while the other part is to study processes that occur in these solutions. READ MORE
