    Sammanfattning : This study primarily focuses on the ways in which companies choose to adapt themselves to the demands of the authorities as based on the Swedish environmental protection act. The time during which the burden upon nature became a serious, important question for companies is a very dramatic phase of a historical process. LÄS MER

  3. 2. Unit Commitment : Computational Performance, System Representation and Wind Uncertainty Management

    Författare :Germán Morales-España; Lennart Söder; Andres Ramos; Paulien M. Herder; Michel Rivier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik; Mathematics; Matematik;

    Sammanfattning : In recent years, high penetration of variable generating sources, such as wind power, has challenged independent system operators (ISO) in keeping a cheap and reliable power system operation. Any deviation between expected and real wind production must be absorbed by the power system resources (reserves), which must be available and ready to be deployed in real time. LÄS MER

  4. 3. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

    Författare :Tarek Dishisha; Bioteknik; []

    Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER

  5. 4. Neural Progenitor Cells in malignancy and injury of the brain. A Trojan Horse fro gliomas?

    Författare :Karin Staflin; CNS Genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; transplantation; Immunologi; Medicine human and vertebrates ; Medicin människa och djur ; Immunology; serology; Glioma; sub ventricular zone; neural progenitor cell;

    Sammanfattning : Gliomas are neoplasms arising in the central nervous system (CNS), and constitute the most common primary brain tumor. They are classified depending on the grade and morphology, from grade I, pilocytic astrocytoma, to grade IV, glioblastoma multiforme (GBM). Glioblastomas constitute a great challenge in treatment due to their disseminating nature. LÄS MER

  7. 5. Traumatic spinal cord injury in South Africa and Sweden : epidemiologic features and functioning

    Författare :Conran Joseph; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Trauma to the human spinal cord typically strikes out of the blue, leaving those surviving the initial ordeal with permanent or temporary deficits in health and functioning. Because of this, traumatic spinal cord injuries (TSCI) impose a significant burden on society. LÄS MER
