    Sammanfattning : Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. LÄS MER

  4. 18. Characterization and treatment of municipal landfill leachates

    Författare :Ulrika Welander; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical chemical treatment; biological treatment; characterization; organic substances; leachate treatment; municipal landfill; Biotechnology; Bioteknik;

    Sammanfattning : Abstract The efficiency of different leachate treatment methods for the removal of refractory organic compounds and ammonium-nitrogen was investigated. The methods evaluated were nitrification, denitrification, adsorption onto activated carbon, precipitation by ferric chloride or aluminum sulphate and oxidation by ozone or Fenton´s reagent. LÄS MER

  5. 19. Axis Fractures in Elderly : Epidemiology and Treatment related outcome

    Författare :Anna-Lena Robinson; Claes Olerud; Yohan Robinson; Bengt Lind; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; odontoid fracture; treatment; elderly; cervical spine; axis fracture; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Axis fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. Knowledge of the incidence of these fractures, as well as their treatment, outcome and mortality rate, will improve knowledge and decision-making processes for this fragile group of patients.
