2. 1. Electronic structure and exchange interactions from ab initio theory : New perspectives and implementations

   Author : Ramon Cardias Alves de Almeida; Olle Eriksson; Anders Bergman; Attila Szilva; R. B. Muniz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio; exchange interactions; non-collinear magnetism; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : In this thesis, the magnetic properties of several materials were investigated using first principle calculations. The ab initio method named real space linear muffin-tin orbitals atomic sphere approximation (RS-LMTO-ASA) was used to calculate the electronic structure and magnetic properties of bulk systems, surface and nanostructures adsorbed on surfaces.

4. 2. Coherent Diffractive Imaging with X-ray Lasers

   Author : Max Felix Hantke; Filipe R. N. C. Maia; Janos Hajdu; Martin Svenda; Edgar Weckert; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

   Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

5. 3. Microstructural, Residual Stress, and Thermal Shock Studies of Plasma Sprayed ZrO2-Based Thermal Barrier Coatings

   Author : Per Bengtsson; R. Taylor; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Thermal barrier coatings (TBCs), with a thickness of 0.4 mm, are today extensively used on the hot parts of both stationary and flying jet engines. The purpose of the TBC is to protect the underlying material from high temperatures and severe thennal shock. READ MORE

6. 4. Dis-placed Desires : Space and Sexuality in South African Literature

   Author : Sanja Nivesjö; Stefan Helgesson; Ann-Sofie Lönngren; Ingo Berensmeyer; Andrew van der Vlies; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; sexuality; space; place; queer theory; Sara Ahmed; Lefebvre; Foucault; South African literature; South Africa; Olive Schreiner; R. R. R. Dhlomo; Nadine Gordimer; J. M. Coetzee; Bessie Head; Phaswane Mpe; Damon Galgut; English; engelska; English;

   Abstract : This study provides a diachronic view of the interweaving of space and sexuality, their interdependency and mutually constitutive aspects, in seven South African English language novels from the early twentieth century until the first decade of the twenty-first century. A key contention is that it is precisely a co-constitutive depiction of space and sexuality that has arisen in this literature as a response to a socio-political climate which has exercised harsh regulation in these two areas.

7. 5. Absorption Characteristics of Periodically Perforated Suspended Ceilings

   Author : Dag Holmberg; Teknisk akustik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; measurement device.; flow resistance; suspended ceilings; periodically perforated facing; resonant absorbers; Room acoustics; building acoustics;

   Abstract : The sound absorption characteristics of resonant absorbers, implemented as perforated suspended inner ceilings attached with thin porous layers, are investigated. Several existing theories model the principal absorption mechanisms, but the interaction with the outer sound field influences the absorption in ways that can be modelled with new approaches.
