  1. 6. Persisterande ductus arteriosus hos hund

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Caroline Jonsson; [2015]
    Keywords : PDA; persisterande ductus arteriosus; hund; patent ductus arteriosus; dog;

    Abstract : Ductus arteriosus (DA) är en förbindelse mellan aorta och truncus pulmonalis som normalt finns hos alla däggdjur under fosterstadiet. Denna kanal har till syfte att shunta blod förbi lungorna tillbaka ut i systemkretsloppet, då gasutbyte sker över placenta och lungorna endast kräver en liten mängd blod för sin egen nutrition och metabolism.

  3. 7. Characterization of viscoelastic properties of an epoxy composite and simulation of time dependent deformation of an annulus seal under load.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Christopher Muturi; [2014]
    Keywords : ;

    Abstract : A new sealing stand-alone tool, i.e. CannSeal to produce a barrier packer or zonal isolation in oil/gas wells has been developed by a Norwegian company (AGR CannSeal AS). The tool allows injection of a fluid into the annulus between the production casing and the surroundings in an oil/gas well. READ MORE

  4. 8. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

    University essay from Lunds universitet/Materialteknik

    Author : Per-Olof Andersson; [2014]
    Keywords : Crystalline metals; Magnetic materials; Hard magnetic materials; Electro-magnetic applications; Single crystalline powder; Powder metallurgy; Fe2B; FeB; Water atomization; Gas Water atomization; non-RE hard magnetic material.; Technology and Engineering;

    Abstract : An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. READ MORE

  5. 9. Pricing and Hedging of Swing Options in the European Electricity and Gas Markets

    University essay from Lunds universitet/Matematisk statistik

    Author : John Hedestig; [2014]
    Keywords : Mathematics and Statistics;

    Abstract : This report outlines a method to price and hedge a generalized swing option based on the European natural gas and electricity markets. The method is model free in that is does not assume a certain spot price dynamics. It only requires a forward curve and European call options prices that cover the delivery period of the swing option. READ MORE

  6. 10. ZnO nanoparticles : synthesis of Ga-doped ZnO, oxygen gas sensing and quantum chemical investigation

    University essay from Institutionen för fysik, kemi och biologi

    Author : Alexander Hagelin; [2011]
    Keywords : ZnO zinc oxide gallium Ga doped indium In O2 oxygen gas sensing quantum chemical quantum chemistry computational chemistry synthesis combustion EDOC electrochemistry wet chemical XRD SEM DOS HOMO LUMO nitrogen dioxide NO2 response Langmuir;

    Abstract : Doped ZnO nanoparticles were synthesized by three different methods – electrochemical deposition under oxidizing conditions (EDOC) , combustion method and wet chemical synthesis – for investigating the oxygen gas sensing response. Ga-doped ZnO was mostly synthesized but also In-doped ZnO was made. READ MORE
