  1. 1. Design of a Leaky-wave Antenna Based on Goubau Line for Imaging Applications

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Roger Bock Filella; [2022]
    Nyckelord :leaky-wave antenna; radar systems; Goubau Line; glide symmetry; dispersion diagram; endfire; broadside;

    Sammanfattning : The project main purpose is to design a prototypeof a leaky-wave antenna (LWA) which will serve as a basisto future manufacturing of a more advanced product withpotential use for an imaging radar system. The antenna consistsof Goubau line corrugations with rectangular radiation patches. LÄS MER

  2. 2. Three-dimensional modelling of the Källfallsgruvan iron oxide deposit, Riddarhyttan ore field, Bergslagen, Sweden: Integrating existing and new data to aid understanding of structural controls and mineral exploration

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Edna Spahic; [2021]
    Nyckelord :Three-dimensional modelling; Mineral exploration; Bergslagen; Riddarhyttan ore field; Källfallsgruvan iron-oxide deposit;

    Sammanfattning : The Bergslagen ore province, located in the Fennoscandian shield in the south-central part of Sweden hosts several metallic mineral deposits, one of them being the Källfallsgruvan iron-oxide deposit in the Riddarhyttan ore field, situated in a high-strain shear belt denoted as the West Bergslagen Boundary Zone (WBBZ).  An accurate 3D geological model of the Källfallsgruvan iron-oxide deposit has been generated to aid understanding of the ore body geometries and calculating volume and tonnage.

  3. 3. The anti-amyloidogenic chaperone DNAJB6 and its interaction with other chaperones

    Kandidat-uppsats, Lunds universitet/Matematisk statistik; Lunds universitet/Kemiska institutionen

    Författare :Gemma Nilsson; [2020]
    Nyckelord :chaperones; DNAJB6; Hsc70; Hsp110; ATP-hydrolysis; Ab42; polyQ; biochemistry; biokemi; Chemistry;

    Sammanfattning : In order to maintain proteins’ functionality their native folding state must be preserved. Chaperones fold other proteins and DNAJ-chaperones may collaborate with Hsc70 chaperones to prevent aggregation of aggregation-prone peptides such as polyQ and Aβ42, which form fibrils in currently incurable diseases as Huntington’s and Alzheimer’s, respectively.

  4. 4. Automated Orienting of Water Molecules in Neutron Crystal Structures

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Axl Eriksson; [2019]
    Nyckelord :Teoretisk kemi; Theoretical chemistry; Crystallography; Neutron crystallography; X-ray crystallography; Phenix.refine; Method development; Model improvement; Chemistry;

    Sammanfattning : A protein’s function is directly related to its structure, which is in a water medium where it is affected by hydrogen bonds and the hydrophobic effect. These interactions are in turn dependent on the water molecules’ orientations around the protein. Therefore, it is vital to have correct orientations for the water molecules. LÄS MER

  5. 5. Seismic tomography as an instrument for structural evaluation in the Printzsköld and Alliansen ore bodies, Malmberget

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Linus Jonsson; [2017]
    Nyckelord :Geology; Seismic tomography; LKAB;

    Sammanfattning : The Malmberget deposit is one of the major apatite iron ores in Europe, located in northern Norrbotten. As the mining in Malmberget proceeds deeper more challenges with the stability have been faced. When the stress distribution of a rock mass exceeds the rock strength energy in form of seismic waves is released. LÄS MER
