  1. 1. Climate and vegetation during the Miocene - evidence from Danish palynological assemblages

    Författare :Linda Larsson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeoenvironment; pollen; climate; Denmark; palynology; Miocene;

    Sammanfattning : Several Danish exposures and one drill core spanning the upper Oligocene-upper Miocene interval of the Cenozoic (i.e., 24–5 Myr ago) were palynologically investigated. LÄS MER

  3. 2. Development of new blood banking strategies for processing and storage of red blood cell components

    Författare :Linda Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The field of red blood cell (RBC) components has been quite uneventful during the last few decades, save for the experimental exploration of alternative additive solution compositions. The reason is likely that the RBC quality has been good enough and the shelf-life of conventional RBC concentrates (RCC) has been long enough to not really motivate the workload that any dramatic changes would implicate.

  4. 3. Digital stereomicroscopy for measurements of deformations, velocity fields and microstructural changes of paper

    Författare :Linda Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : There is a strongly increasing request of measuring systems for mechanical properties studies, for example in the paper industry. Paper research is today not only concentrated to flock studies, weight and quality controls of the paper but also focussing of mechanical behaviours in the fibre scale. LÄS MER

  5. 4. Analysis of concepts to reduce the environmental impact of aviation

    Författare :Linda Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turboprop; Contrails; Turbofan; Aviation; Open rotor; Aircraft engine; Environment;

    Sammanfattning : The average yearly increase in passenger kilometres travelled by air has been 5.8 % over the last 40 years. Fortunately the fuel consumption has not increased at the same rate. Over the same time period the average increase in fuel sold has been 2. LÄS MER

  7. 5. Aviation and the Environment- Evaluation of High Propulsive Efficiency Engines

    Författare :Linda Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft engine; Environment; Open rotor; Turbofan; Aviation;

    Sammanfattning : There has been more than a tenfold increase in passenger kilometers traveled over the last 40 years. The highest rate of growth today is in developing countries such as China and India. These countries also have the two largest populations in the world. LÄS MER
