  1. 36. Peptide folding and local unfolding of SOD1 in the presence of interacting macromolecular crowders - a Monte Carlo approach

    Författare :Anna Bille; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; protein folding; SOD1; crowding; Fysicumarkivet A:2016:Bille;

    Sammanfattning : A protein chain often folds into a functional, specific three dimensional structure. Failurein this process can in some cases lead to disease, e.g. the misfolding disease ALS. LÄS MER

  3. 37. Simulations of water clustering in vapour, hydrocarbons and polymers

    Författare :Erik Johansson; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cluster; gibbs ensemble; monte carlo; water; polyethylene; external field; ions; Energi och material;

    Sammanfattning : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. LÄS MER

  4. 38. Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations

    Författare :Shirin Abbasinejad Enger; Hans Lundqvist; Anders Ahnesjö; Irena Gudowska; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; External Beam Radiotherapy; Gadolinium Neutron Capture Therapy; Gadolinium Neutron Capture Brachytherapy; Targeted Radionuclide therapy; Detector Response Modelling; Monte Carlo Simulation.; Radiological physics; Radiofysik;

    Sammanfattning : Developing radiation delivery systems for optimisation of absorbed dose to the target without normal tissue toxicity requires advanced calculations for transport of radiation. In this thesis absorbed dose and fluence in different radiotherapy applications were calculated by using Monte Carlo (MC) simulations. LÄS MER

  5. 39. Computational Studies of Metal Clusters and Carbon Nanotubes

    Författare :Anders Börjesson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; metal clusters; nanotubesmetal junction; melting temperatures; nanotechnology; molecular dynamics; monte carlo; tight binding; atomistic simulations; Energi och material;

    Sammanfattning : Carbon nanotubes constitute a promising candidate material in the realisation of nanoscaled electronics. This requires the ability for systematic production of carbon nanotubes with certain properties. This is called selective carbon nanotube growth. LÄS MER

  7. 40. Multiscale simulations of soft matter: systematic structure-based coarse-graining approach

    Författare :Alexander Mirzoev; Alexander Lyubartsev; Nico van der Vegt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiscale modeling; Monte Carlo; Molecular dynamics; ion solution; lipid bilayer; coarse-graining; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : The soft matter field considers a wide class of objects such as liquids, polymers, gels, colloids, liquid crystals and biological macromolecules, which have complex internal structure and conformational flexibility leading to phenomena and properties having multiple spacial and time scales. Existing computer simulation methods are able to cover these scales, but with different resolutions, and ability to link them together performing a multiscale simulation is highly desirable. LÄS MER
