    Sammanfattning : Leveranser och unionsinterna förvärv i mervärdesskatterätten – Supplies and Intra-Union Acquisitions of Goods under VATThe objective of this thesis is to analyze the VAT rules regarding supplies and intra-union acquisitions of goods based on the notion that a purpose of harmonized VAT is to further the internal market. This objective originates from the tension that has been created between the two mentioned transaction types, where a transaction involving goods is treated one way if it is carried out domestically and another if it is done in a cross-border context.

  3. 2. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Författare :Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    Sammanfattning : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.

  4. 3. Electron beam melting: Impact of part surface properties on metal fatigue and bone ingrowth

    Författare :Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Ola Harrysson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing AM ; Electron Beam Melting EBM ; As-built surfaces; Bone Ingrowth; Metall Fatigue; Machined Surfaces; Hirtisation; Hot Isostatic Pressing HIP ;

    Sammanfattning : AbstractThe aim of this thesis is to investigate aspects on how additive manufacturing (AM) contributes to functional bone implants with the use of the electron beam melting (EBM) technology. AM manufactures parts according to computer-aided design, and the EBM technology melts powder using an electron beam, which acts similar to a laser beam. LÄS MER

  5. 4. SURFACE PROPERTIES OF IMPLANTS MANUFACTURED USING ELECTRON BEAM MELTING

    Författare :Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Felicia Suska; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron beam melting; blood coagulation; bone ingrowth; surface roughness; process parameters;

    Sammanfattning : This thesis summarizes the results concerning the manufacture of medical implants for bone replacement using electron beam melting (EBM) which is an additive manufacturing (AM) technology, and aims to satisfy the engineering needs for the medical functionality of manufacturing technology. This thesis has focused on some microscopic properties for surfaces and bone integration. LÄS MER
