  2. 1. From sequence to function : Comparative studies of insect olfactory receptors

    Author : Xiaoqing Hou; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Olfactory receptor; Heterologous expression; Pheromone; Plant volatile; Insect;

    Abstract : In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. READ MORE

  4. 2. Mechanical Properties of Transition Metal Alloys from First-Principles Theory

    Author : Xiaoqing Li; Levente Vitos; Manuel Richter; KTH; []
    Keywords : ;

    Abstract : The aim of the thesis is to investigate the alloying effect on the mechanical properties of random alloys using the all-electron exact muffin-tin orbitals methodin combination with the coherent-potential approximation. The second-order elastic constants describe the mechanical properties of materials in the small deformation region, where the stress-strain relations arelinear. READ MORE

  5. 3. Mechanical Properties of Transition Metal Alloys from First-PrinciplesTheory

    Author : Li Xiaoqing; Levente Vitos; Mojmír Šob; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of the thesis is to investigate the alloying and temperature effects on the mechanical properties of body-centered cubic (bcc) random alloys. We employ the all-electron exact muffin-tin orbitals method in combination with the coherent-potential approximation. READ MORE
