  1. 1. Forming wide-orbit planets via pebble accretion

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Nerea Gurrutxaga; [2023]
    Nyckelord :Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

    Sammanfattning : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. LÄS MER

  3. 2. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

    Master-uppsats,

    Författare :Jesper Brovall; [2022-01-13]
    Nyckelord :Medical physics; Dosimetry; MRI; Radiation therapy;

    Sammanfattning : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. LÄS MER

  4. 3. Idealised remediation scenario in two small-scale intersecting fractures

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Agnes Zúniga Ekenberg; [2022]
    Nyckelord :;

    Sammanfattning : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. LÄS MER

  5. 4. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Lea Enenkelová; [2021]
    Nyckelord :sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

    Sammanfattning : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

  7. 5. Bindningsstyrka mellan komposit och porslin för metallkeramik med förbehandling av olika  reparationssystem

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Linnea Liljenborg; Ghinwah Chaaban; [2021]
    Nyckelord :Adhesive resin; bonding strength; composite material; metal-ceramics; porcelain repair system; Adhesiv resin; bindningsstyrka; kompositmaterial; metallkeramik; reparationssystem.;

    Sammanfattning : Syfte: Syftet med föreliggande in-vitro studie är att undersöka olika kompositbaserade reparationssystem och dess bindningsstyrka till porslin för metallkeramiska konstruktioner. Material och metod: Metallstavar tillverkades via CAD/CAM i CoCr (5.0x5.0x15. LÄS MER
