  1. 1. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

    Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

    Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER

  3. 2. Open vs closed exposure of palatally displaced canines : clinical, patient-related outcomes and health economics

    Författare :Margitha Björksved; Farhan Bazargani; Rune Lindsten; Kristina Arnrup; Jonathan Sandler; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The maxillary permanent canine usually erupts in the mouth between the ages of 11 and 12 years. Sometimes the canines are displaced toward the palatal side of the dental arch and eruption is disturbed. Palatally displaced canines (PDCs) are a frequent dental anomaly, present in 2% of the young population. LÄS MER

  4. 3. Learning from Multi-Objective Optimization of Production Systems : A method for analyzing solution sets from multi-objective optimization

    Författare :Catarina Dudas; Henrik Boström; Amos H.C. Ng; Johan Ölvander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data mining; Post-optimization analysis; Production system analysis; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : The process of multi-objective optimization involves finding optimal solutions to several objective functions. However, these are typically in conflict with each other in many real-world problems, such as production system design. LÄS MER

  5. 4. Development and Use of Optical Sensors in Modern Analytical Chemistry

    Författare :Aron Hakonen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical sensors; Optodes; Imaging sensors; Fluorescence; pH; Ammonium; Sensing; Nanoparticle enhancement; Plasmonics;

    Sammanfattning : A successful long-term high resolution imaging experiment in marine sediments was performed (17 days within the sample; Paper I). The time correlated calibration procedure was evolved to include parametric sigmoidal and logarithmic functions to provide three of the best performing (optical) pH sensors available up to date (Papers II, III and IV), precision of these sensors were in the 0.

  7. 5. Traction force and long-term outcome in children born after vacuum-assisted delivery

    Författare :Stefhanie Romero; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Vacuum-assisted delivery (VAD) is used in cases of dystocia or foetal distress in the second stage of labour. The frequency of VADs differs around the world, and in Sweden they account for six to nine percent of all deliveries. LÄS MER
