  1. 1. Potential Use of Aquifer Thermal Energy Storage System in Arid Regions

    Författare :Qais Al-Madhlom; Jan Laue; Nadhir Al-Ansari; Sabbar Abdullah Saleh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer thermal energy storage system; ATES; site selection; seepage velocity; aquifer vulnerability; DRASTIC; arid regions; ArcMap GIS; Soil Mechanics; Geoteknik;

    Sammanfattning : After the Oil Crises in 1973, which meant higher energy costs, the world started to look for other sources of energy. This led to the development of renewable energy techniques. Because of the intermittent nature of renewable energy, storage systems were also developed. LÄS MER

  2. 2. Soil Modification by adding small amounts of binders : A laboratory study

    Författare :Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.

  3. 3. Structural and functional properties of transthyretin

    Författare :Anders Karlsson; A. Elisabeth Sauer-Eriksson; Salam Al-Karadaghi; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Amyloidosis; X-ray crystallography; Protein structure; Protein; Structural biology; Strukturbiologi;

    Sammanfattning : The hereditary transthyretin (TTR) amyloidoses are rare, and in severe cases, fatal disorders caused by mutations in the TTR gene. The clinical picture is diverse, involving neuropathies and myopathies, and mainly depends on the causative mutation and the sites and rates of amyloid deposition. LÄS MER

  4. 4. Copper(II) Azido Complexes: Synthesis, X-ray structures, thermal and magnetic properties

    Författare :Al-Shimaà A A Massoud; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cu II complexes; bridging µ1; quinoxaline; 2; pyrazinetetrazolate; quinolinecarboxylate; 1–N3; 5-dimethylpyrazine; ferromagnetic interactions;

    Sammanfattning : This thesis focuses on the synthesis and X-ray structure analysis of seven copper(II) and one cobalt(II) azido coordination polymer with quinoline and pyrazine derivatives as bridging co-ligands. The synthesis of these complexes were done by direct mixing of the metal salt (Cu(NO3)2 and CoCl2) and the organic ligand (pyrazinecarbonitrile, quinoxaline, quinoline-4-carboxylic acid and 2,5-dimethylpyrazine) solutions followed by the dropwise addition of aqueous sodium azide (NaN3) with continuous stirring.

  5. 5. Flourescence properties of trendy molecules studied with synchrotron radiation

    Författare :Gemma Vall-Llosera; Elisabeth Rachlew-Källne; Ahmed Al-Khalili; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis summarises the experimental results on molecular spectroscopy of gas phase molecules using synchrotron radiation in the UV- VUV and soft-X rays regions. The results of applying Photon Induced Fluorescence Spectroscopy (PIFS) to D2, H2S, H2O and pyrimidine are presented and discussed. LÄS MER
