    Sammanfattning : Transport of people and freight on-road have a big impact on the total energy use in the world. The majority of these transports is propelled with diesel engines and the reason is simply that the diesel engine is better than the gasoline engine due to lower fuel consumption. But the cost of this is the increase in dangerous nitrogen oxides (NOx). LÄS MER

  4. 3. Galactoglucomannan recovery from softwood spent sulfite liquor: Challenges, process design and techno-economic evaluations

    Författare :Basel Al-Rudainy; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galactoglucomannan; Lignin; Lignosulfonates; Lignin-carbohydrate-complexes; Membrane filtration; Dead-end filtration; Precipitation; Adsorption;

    Sammanfattning : In the production of pulp and paper, water-soluble components, such as hemicellulose, monosaccharides, and lignin, are released and accumulate in the process water. The process water is usually concentrated and incinerated for heat generation and the recovery of pulping chemicals, such as in the Kraft and sulfite processes. LÄS MER

  5. 4. Stereotactic body radiation therapy of primary lung cancer and metastases

    Författare :Karin Lindberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Stereotactic body radiation therapy (SBRT) has been assessed by both retrospective and prospective studies showing excellent treatment outcome with acceptable toxicity and high grade of local control. However, late presenting effects as well as further evaluating toxic effects in relation to dose-volume parameters at high-fraction doses and clinical characteristics is of the utmost importance in order to further develop the clinical application of this method.

    Sammanfattning : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.
