  2. 6. Urban green networks : a socio-ecological framework for planning and design of green and blue spaces in Sweden and China

    Author : Na Xiu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Multi-disciplinary research is needed to address the issue of urban landscape fragmentation. Based on empirical and theoretical context analysis, a framework of network-based, socio-ecological methods and indicators that can be effectively applied by practitioners in different geographical locations was developed in this thesis.

  4. 7. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies

    Author : Na Kong; Mingdi Yan; Joseph J. Barchi Jr; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Bioteknologi; Biotechnology;

    Abstract : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

  5. 8. Theoretical Studies on Electronic and Vibrationally Resolved Multi-Photon Absorption and Dichroism

    Author : Na Lin; Yi Luo; Marcel Nooijen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multi-photon absorption and dichroism; Vibronically resolved spectroscopy; Quantum chemistry; Kvantkemi;

    Abstract : This thesis presents time-dependent density functional theory studies on electronic and vibronically resolved linear and nonlinear optical absorption and dichroism spectra of organic molecules. Special attention has been paid to the influence of solvent environment and molecular vibrations on one-, two- and three-photon absorption and one- and two-photon circular dichroism. READ MORE

  6. 9. Endoplasmic reticulum function in dendrites and dendritic spines of hippocampal neurons

    Author : Ai Na Ng; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endoplasmic reticulum; primary culture; dendritic spines; live cell imaging; STIM1; carbachol; store-operated calcium entry; 3; familial Alzheimer s disease; 5-dihyroxyphenyglycine;

    Abstract : In the hippocampus, dendritic spines are compartmentalized postsynaptic micro-domains in the excitatory synapse. Subsets of bigger and mushroom-shaped hippocampal dendritic spines contain tubules and cisterns of endoplasmic reticulum (ER) that are connected to the soma and dendrites of the neuron. READ MORE

  7. 10. A Linearized Navier-Stokes Equations Methodology for Aeroacoustic and Thermoacoustic Simulations

    Author : Wei Na; Susann Boij; Gunilla Efraimsson; Niklas Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linearized Navier-Stokes Equations LNSE ; frequency domain; tube row heat exchanger; hybrid liner; thermoacoustic instabilities; entropy waves; Rijke-tube; nozzle; Engineering Mechanics; Teknisk mekanik;

    Abstract : Aeroengine noise is one of the dominating noise sources in today’s aircraft. Reduction of the aeroengine noise is related to multiphysics phenomena, and that is subject to different mechanisms, e.g., the coupling between turbulence, flame and sound waves. READ MORE
