  1. 16. Bird-parasite interactions Using Sindbis virus as a model system

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin M. Lindström; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Carduelis chloris; Sindbis virus; host-parasite interaction; ornament; social dominance; testosterone; sexual selection; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; populationsbiologi; Population Biology;

    Abstract : This thesis focuses on the evolutionary interactions between birds and a parasite, the mosquito-borne Sindbis virus (Togaviridae, Alphavirus). In conclusion, the results show that the Sindbis virus is widespread among birds, and that the fitness of infected hosts may be reduced by the virus. READ MORE

  2. 17. Transport and environment incentive policy instruments : effects and interactions

    University dissertation from Örebro : Örebro universitet

    Author : Xing Liu; Lars Hultkrantz; James Odeck; [2013]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Congestion pricing; Equity effects; Modal choice; Social marginal cost; Externalities; Transport taxation; Carbon tax; Carbon leakage; Computable General Equilibrium Model; VTTS; Simultaneous decision model; Random utility model; Logistics cost minimization; Additionality; Klimp; Climate subsidy program; Subsidy; CDM; Business Studies; Företagsekonomi;

    Abstract : This dissertation studies issues related to the evaluation of the effects and interactions of transport and environmental incentive policy instruments. Essay 1: Green cars sterilize congestion charges: a model analysis of the reduced impact of Stockholm road tolls calibrates a modal-choice model with data from the Stockholm road toll and uses it to study the sensitivity of congestion toll effects to some seemly subtle changes in the toll system design and external circumstances.

  3. 18. Endothelial-leukocyte interactions

    University dissertation from Maria Olofsson, Department of Cell and Molecular Biology, Box 94, S-221 00 Lund, Sweden

    Author : Maria Olofsson; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Histology; endothelial cell; leukocyte; apoptosis; mitochondria; heparin binding protein; vascular permeability; E-selectin; migration; rolling; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Abstract : This thesis describes early inflammatory responses involving interactions between leukocytes and the endothelial lining of the blood vessel wall. An adhesion molecule, E-selectin, which is upregulated on interleukin-1 activated endothelium, was found to mediate rolling between leukocytes and endothelial cells in vivo. READ MORE

  4. 19. Protein-surfactant interactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ank Valstar; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. READ MORE

  5. 20. Bio-Nano Interactions Synthesis, Functionalization and Characterization of Biomaterial Interfaces

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.
