  1. 16. Perspectives on Biofilms for the Removal of Organic Micropollutants in Wastewater

    Författare :Ellen Edefell; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; wastewater; biofilm; ozonation; activated carbon; powdered activated carbon; granular activated carbon; biological degradation; Moving bed biofilm reactor;

    Sammanfattning : The use of biofilms to improve the removal of organic micropollutants in waste¬water treatment plants (WWTPs) has been investigated. The work is divided into two parts. In the first part, the use of biofilms for the biological degradation of micro¬pollutants was investigated. LÄS MER

  3. 17. On Modeling and Implementing Shopfloor Control Systems

    Författare :Niklas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; reference architectures; implementation; shopfloor control;

    Sammanfattning : One of the key factors that hold shopfloor control (SFC) software evolution back is the exorbitant cost, time, complexity, and inflexibility of developing customized SFC software solutions. The development and maintenance life-cycle of SFC software is characterized by lock-in problems. LÄS MER

  4. 18. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    Författare :Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Bioteknologi; Biotechnology;

    Sammanfattning : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. LÄS MER

  5. 19. Transesophageal Echocardiography in Patients Undergoing Elective Coronary Artery Bypass Surgery

    Författare :Ingrid Palmgren; Russell Anderson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; transesophageal echocardiography; low-dose dobutamine; viability; coronary artery bypass; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; anestesiologi; Anaesthesiology;

    Sammanfattning : Transesophageal echocardiography (TEE) has become a useful tool in monitoring the heart in patients during open-heart surgery. This study was undertaken to evaluate whether it is feasible to use TEE to assess left ventricular myocardial viability in anesthetized patients scheduled for coronary artery bypass grafting (CABG).

  7. 20. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

    Författare :Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Advanced wastewater treatment; WWTP; pilot plant; pharmaceutical residues; removal of pharmaceuticals; activated carbon; ozonation; nanofiltration; biomarker; Baltic Sea; Bioteknologi; Biotechnology;

    Sammanfattning : Pharmaceutical residues are found in the environment due to extensive use in human and veterinary medicine. The active pharmaceutical ingredients (APIs) have a potential impact in non-target organisms. Municipal wastewater treatment plants (WWTPs) are not designed to remove APIs. LÄS MER
