  1. 1. Photoemission and Characterization of Neutrophils and Nanoparticles : Energy Mapping and Elemental Composition with sub-µm Resolution

    Författare :Andreas Skallberg; Kajsa Uvdal; Christelle Prinz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Imaging and visualization of cells and tissues are important when studying various biological phenomena. The ability to provide spatial information with molecular and chemical specificity may increase our insight and understanding of biological problems within life sciences. LÄS MER

  3. 2. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass

    Författare :Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

    Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER

  4. 3. Dentofacial morphology in Turner Syndrome karyotypes

    Författare :Sara Rizell; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; Turner syndrome; genetics; karyotype; geno-phanotype correlation; anthropometrics; craniofacial morphology; dental arch; dental crown width; enamel; primary teeth; elemental composition;

    Sammanfattning : The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. LÄS MER

  5. 4. Studies of the Elemental Composition of Airway Surface Liquid with Relevance to Cystic Fibrosis

    Författare :Viengphet Vanthanouvong; Godfried M. Roomans; Isabelle Sermet-Gaudelus; Uppsala universitet; []
    Nyckelord :Anatomy; airway surface liquid; cystic fibrosis; Na; K; Cl; X-ray microanalysis; Anatomi;

    Sammanfattning : Cystic fibrosis (CF) is an inherited disease with symptoms mainly in the respiratory tract. The airway epithelium is covered with a thin layer of fluid, the airway surface liquid (ASL). The volume and composition of ASL are important in the pathogenesis of cystic fibrosis. The composition of ASL was determined. LÄS MER

  7. 5. Development of Composition Gradients in Cemented Carbides

    Författare :Robert Frykholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPMA; DICTRA; functionally graded materials; gradient sintering; diffusion; APFIM; thermodynamic modelling; SEM; surface zones;

    Sammanfattning : This thesis concerns the formation of tough surface zones, depleted of cubic carbo-nitrides, in cemented carbides. Several materials with varied phase compositions, binder phase volume fraction, and carbon content have been investigated. LÄS MER
