1. 1. Kraft, form, transformationer : Om kinestetisk musikalitet och kroppsvärldande i pojkars krigslek

   Författare :Ebba Theorell; Inger Eriksson; Ulrika von Schantz; Cecilia Roos; Elin Eriksen Ødegaard; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; War play; improvisation; proprioception; perception; aesthetics; kinestesia; space; body-subject; transduction; transformation; force; form; time; becoming; attention; sensation; the thinking body and body-worlding; ämnesdidaktik med inriktning mot de estetiska ämnenas didaktik; Teaching and Learning with Specialisation in the Arts Education;

   Sammanfattning : War play has generally been studied with violence as a central perspective, investigating its impact on children’s aggression, both in a positive and negative sense. Some research results have claimed that war play can contribute to normalising or even encouraging violent behavior amongst children, while other results have claimed that children can develop important physical, cognitive or social skills through war play.

3. 2. Surface interactions and adsorbate structures : An atomic force microscopy study

   Författare :Goran Bogdanovic; KTH; []
   Nyckelord :atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

   Sammanfattning : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

4. 3. Alexandria: A General Drude Polarizable Force Field with Spherical Charge Density

   Författare :Mohammad Mehdi Ghahremanpour; David Van der Spoel; Kresten Lindorff-Larsen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular mechanics; Force field; Drude oscillator model; Alexandria library; GROMACS; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Sammanfattning : Molecular-mechanical (MM) force fields are mathematical functions that map the geometry of a molecule to its associated energy. MM force fields have been extensively used for an atomistic view into the dynamic and thermodynamics of large molecular systems in their condensed phase. LÄS MER

   Sammanfattning : The object of this thesis is to apply scanning probemicroscopy (SPM) to the field of advanced powder processing.Measurement of interparticle surface forces at conditionsrelevant to ceramic processing has been performed together withthorough studies of powder friction. LÄS MER

7. 5. Fighting microbial infections with force fields: Evaluating conformational ensembles of intrinsically disordered proteins

   Författare :Stephanie Jephthah; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; force field; Monte Carlo; coarse-grained modeling; simulation; intrinsically disordered protein; histatin 5; small-angle x-ray scattering; circular dichroism; atomistic MD simulations; all-atom protein models;

   Sammanfattning : The main goal of this compilation thesis has been to investigate the conformational ensemble of the intrinsically disordered protein (IDP) histatin 5 by using a mixture of experimental and computational techniques including, but not limited to, small-angle X-ray scattering (SAXS), circular dichroism (CD) spectroscopy, atomistic molecular dynamics (MD) simulations, and coarse-grained Monte Carlo (MC) simulations. Histatin 5 is a peptide of particular interest for two reasons. LÄS MER
