  1. 6. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Författare :Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Sammanfattning : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. LÄS MER

  3. 7. Sjögren's syndrome: epidemiological risk factors and biomarkers

    Författare :Peter Olsson; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sjögren syndrome; cytokine; Interferon Type I; Cigarette smoking;

    Sammanfattning : Primary Sjögren’s syndrome (pSS) is an autoimmune disease, primarliy affecting women, characterised by inflammation and destruction of exocrine glands with a prevalence of 0.01-0.09%. About one-third of the patients also suffer from extraglandular manifestations e. LÄS MER

  4. 8. Exploring N-alicyclic quaternary ammonium functional polymers as hydroxide exchange membranes

    Författare :Joel Olsson; Centrum för analys och syntes; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte membrane; Anion exchange membranes; Anion exchange membrane fuel cells; Structure-property relationship; Quaternary ammonium cations; Alkaline stability; Synthesis; Characterization;

    Sammanfattning : As the global power generation is shifted toward renewable and intermittent sources, the importance of fuel cells and other energy storage and conversion devices is continually increasing. However, many of these technologies are still under development and further research is necessary before they can be implemented. LÄS MER

  5. 9. Gradient echo-based quantitative MRI of human brain at 7T : Mapping of T1, MT saturation and local flip angle

    Författare :Hampus Olsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MR studies; magnetic resonance MR ; 7 Tesla; T1 mapping; magnetization transfer saturation; Flip angle mapping; spoiled gradient echo; MR studies; magnetic resonance MR ; 7T; T1 mapping; magnetization transfer saturation; Flip angle mapping; spoiled gradient echo;

    Sammanfattning : Quantitative MRI (qMRI) refers to the process of deriving maps of MR contrast parameters, such as relaxation times, from conventional images. If the qMRI maps have a high degree of precision and a low degree of bias, they can be compared longitudinally, across subjects, and (ideally) between measurement protocols and research sites.

  7. 10. Last-mile delivery services in retail : a consumer-centric approach

    Författare :John Olsson; Förpackningslogistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unattended home delivery; customer experience; customer expectations; circular business model innovation;

    Sammanfattning : The retail industry faces a multitude of complex sustainability challenges, which calls for transformational change. While the retail industry is a major driver of production and consumption patterns, it also offers significant potential to reduce global greenhouse gas emissions. LÄS MER
