  1. 1. Calculation of magnetism and its crystal structure dependence

    Författare :Peter James; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : The subject of the present thesis is a theoretical investigation of magnetism and its crystal structure dependence by means of electronic-structure calculations from first principles. The theoretical treatment is based on density functional theory and the so called linear muffin-tin orbital method is used in its full-potential version as well as in an atomic sphere approximation.

    Sammanfattning : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

  3. 3. Perpetual borders : German-Polish cross-border contacts in the Szczecin area

    Författare :Péter Balogh; Gunnel Forsberg; Thomas Lundén; James W. Scott; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cross-border regional development; Polish-German border; Szczecin; national identities; border attitudes; the Other; kulturgeografi; Human Geography; Östersjö- och Östeuropaforskning;

    Sammanfattning : Borderlands are often peripheral geographically, administratively, and economically. A particularly illustrative case is the Szczecin area at the border between Poland and Germany, where a large city on one side neighbours to a sparsely populated hinterland on the other. LÄS MER

  4. 4. Exploring the vibration control potential of magneto-sensitive rubber

    Författare :Peter Blom; Leif Kari; James Busfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; magneto-sensitive rubber; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Two new aspects of the dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber are highlighted: the existence of an amplitude dependence of the shear modulus—referred to as the Fletcher–Gent effect—for even small displacements, and the appearance of large MS effects. These results have been obtained experimentally and are subsequently used to model two examples of magneto-sensitive rubber isolators to show how by means of MS rubber they can be improved. LÄS MER

  5. 5. Origen’s References to Heracleon : A Quotation-Analytical Study of the Earliest Known Commentary on the Gospel of John

    Författare :Carl Johan Berglund; James Anthony Kelhoffer; Anders Ekenberg; Peter W. Martens; Tobias Nicklas; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Heracleon; Origen; Fourth Gospel; Gnosticism; Valentinianism; Quotation Analysis; Second Century; Early Christianity; Nya testamentets exegetik; New Testament Exegesis;

    Sammanfattning : This study of Origen’s references to the second-century author Heracleon addresses two problems in previous research: Scholars have regularly presumed that every statement Origen attributes to Heracleon is equivalent to a verbatim quotation, and that Heracleon’s beliefs conform to those described in heresiological sources. The study develops a method of quotation analysis that uses variations in Origen’s attribution formulas to categorize the almost two hundred references as “verbatim quotations,” “summaries,” “explanatory paraphrases,” or “mere assertions.
