  1. 1. Nanomagnetic and Micromagnetic Properties of Rocks Minerals and Sulphide Oxidation Products

    Detta är en avhandling från Department of Geology, Lund University

    Författare :Erik Eneroth; Lund University.; Lunds universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; multi-domain; single-domain; ilmenite; magnetite; maghemite; hematite; pyrite; marcasite; fysisk geografi; Geologi;

    Sammanfattning : Magnetic and related properties of rocks and products from oxidation of sulphide minerals have been investigated with magnetisation measurements (rocks and oxidation products), magnetic force microscopy (rocks), scanning electron microscopy (rocks and oxidation products), transmission electron microscopy (oxidation products), Mössbauer spectroscopy (oxidation products) and powder X-ray diffraction (oxidation products). The investigations have shown the following: During thermal oxidation of pyrite (cubic FeS2) and marcasite (orthorombic FeS2) in air, nano-crystals of a-Fe2O3 and g-Fe2O3 were formed. LÄS MER

  2. 2. Domain rearrangement and creation in protein evolution

    Detta är en avhandling från Stockholm : Institutionen för biokemi och biofysik

    Författare :Diana Ekman; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Theoretical chemistry Bioinformatics; NATURVETENSKAP Kemi Teoretisk kemi Bioinformatik; Biochemistry; biokemi;

    Sammanfattning : Proteins are composed of domains, recurrent protein fragments with distinct structure, function and evolutionary history. Some domains exist only as single domain proteins, however, a majority of them are also combined with other domains. LÄS MER

  3. 3. The character of magnetic records of deformed soft sediments with emphasis on liquefaction structures

    Detta är en avhandling från Stockholm : Institutionen för geologi och geokemi

    Författare :Guangyu Sun; Stockholms universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; sediments; deformation; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Sammanfattning : In this thesis the characteristics of magnetic records in deformed soft sediments during postglacial time in Sweden are studied. Magnetic records refer in this study to magnetic remanence (NRM and ChRM) and susceptibility, including its anisotropy (AMS). LÄS MER

  4. 4. Creation of new proteins - domain rearrangements and tandem duplications

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Åsa Björklund; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Other biology Bioinformatics; NATURVETENSKAP Biologi Övrig biologi Bioinformatik; biokemi; Biochemistry;

    Sammanfattning : Proteins are modular entities with domains as their building blocks. The domains are recurrent protein fragments with a distinct structure, function and evolutionary history. During evolution, proteins with new functions have been invented through rearrangements as well as differentiation of domains. LÄS MER

  5. 5. Interacting Magnetic Nanosystems An Experimental Study Of Superspin Glasses

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mikael Svante Andersson; Uppsala universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spin glass; SQUID magnetometry; maghemite; magnetism; nanoparticles;

    Sammanfattning : This thesis presents experimental results on strongly interacting γ-Fe2O3 magnetic nanoparticles and their collective properties. The main findings are that very dense randomly packed (≈60%) γ-Fe2O3 nanoparticles form a replica of a spin glass. LÄS MER
