  1. 1. Aspects of Optimisation of Separation of Drugs by Chemometrics

    Författare :Valérie Harang; Douglas Westerlund; Sven P. Jacobsson; Bo Karlberg; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; optimisation; separation; chemometrics; high performance liquid chromatography; electrodriven techniques; microemulsion electrokinetic chromatography; statistical experimental design; molecular modelling; chiral separation; cellobiohydrolase; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. LÄS MER

  2. 2. Controlled dust separation : theoretical and experimental study of the possibilities of controlled dust separation in copper producing processes

    Författare :Caisa Samuelsson; Luleå tekniska universitet; []

    Sammanfattning : Dust is generated in high temperature processes, such as incineration plants, power plants and within the metallurgical industry. The amount of dust generated, chemical and mineralogical composition of the dust as well as physical properties will largely depend on the process generating the dust but also on the off gas system used.

  3. 3. Chromatographic separation of wood constituents

    Författare :Niklas Westerberg; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; mathematical modelling.; Norway spruce; separation; chromatography;

    Sammanfattning : In a modern kraft pulp mill only about 45 % of the incoming wood is present in the pulp and it is mainly composed of cellulose. The remainder of the wood, which is dissolved in order to liberate the cellulose fibres, e.g., hemicellulose and lignin, ends up in the mill´s recovery boiler to recover the latent energy. LÄS MER

  4. 4. Acoustic separation of submicron particles in gaseous flows

    Författare :Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Nyckelord :Acoustic; submicron particles; gaseous flows; separation; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.

  5. 5. Care of the newborn infant during maternal-infant separation

    Författare :Kerstin Erlandsson; Mälardalens högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :separation; father-infant bonding; full-term; skin-to-skin care; cesarean birth; cry; prefeeding; breathing; phenomenology; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; separation; father-infant bonding; full-term; skin-to-skin care; cesarean birth; cry; prefeeding; breathing; phenomenology;

    Sammanfattning : The overall aim of the thesis was to describe care of the newborn infant immediately after birth, during maternal-infant separation; the father as primary caregiver and the mother’s experiences of separation and later reunion with the infant, in order to enhance development of care for the newborn infant during maternal-infant separation. In study I, II and III a phenomenological approach was used to gain access to mothers’ and fathers’ lived experiences (I, III) and lifeworld (II). LÄS MER
