2. 1. Transition in Particle-laden Flows

   Author : Joy Klinkenberg; Luca Brandt; Shuisheng He; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

   Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

4. 2. Transcription regulation and growth phase transition in hyperthermoacidophilic archaea

   Author : Kun Wang; Ann-Christin Lindås; Finn Werner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Archaea; Sulfolobus; Transcription regulation; Lrp; TetR; BarR; ChIP-seq; RNA-seq; Transcriptome; growth phase transition; molekylär biovetenskap; Molecular Bioscience;

   Abstract : Organisms from the domain Archaea are ubiquitously represented on our planet and encompass diverse fascinating organisms. The genus Sulfolobus belonging to the phylum Crenarchaeota including hyperthermoacidophilic strains that grow optimally at 65-85°C and pH 2-3. READ MORE

5. 3. Phase-field modeling of diffusion controlled phase transformations

   Author : Irina Loginova; KTH; []
   Keywords : phase-field; dendritic growth; grain boundary; Widmanstaetten plate; solidification;

   Abstract : Diffusion controlled phase transformations are studied bymeans of the phase-field method. Morphological evolution ofdendrites, grains and Widmanst\"atten plates is modeled andsimulated.Growth of dendrites into highly supersaturated liquids ismodeled for binary alloy solidification.

6. 4. Stability analysis of channel flow laden with small particles

   Author : Joy Klinkenberg; Luca Brandt; Cristian Marchioli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; Direct Numerical Simulations; multi-phase flow; heavy particles; light particles; particle-laden;

   Abstract : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. READ MORE

7. 5. Hg Cuprate Superconductors Technological and Conceptual Tools

   Author : Rafael Gatt; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; high pressure; pulsed laser deposition; crystal growth; high temperature superconductors; cluster calculations; flat bands; thin oxide films; powder diffraction; structure refinement; phase transition; electronic structure; liquid phase epitaxy;

   Abstract : This work concerns superconductivity in the cuprates. It touches some of the problems that this field displays. As a representing case, the Hg based cuprates are chosen. READ MORE
