  1. 1. Porous Polymeric Monoliths by Less Common Pathways : Preparation and Characterization

    Författare :Ahmed Elhaj; Knut Irgum; Sebastiaan Eeltink; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Monolith; commodity polymer; thermally induced phase separation; dissolution-precipitation; polymer solvents; porogenic polymer; step-growth polymerization; separation science; melamine-formaldehyde;

    Sammanfattning : This thesis focuses on my endeavors to prepare new porous polymeric monoliths that are viable to use as supports in flow-through processes. Polymer monoliths of various porous properties and different chemical properties have been prepared utilizing the thermally induced phase separation (TIPS) phenomenon and step-growth polymerization reactions.

    Sammanfattning : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. LÄS MER

  4. 4. Tactile touch in intensive care : Nurses' preparation, patients' experiences and the effect on stress parameters

    Författare :Maria Henricson; Bengt Fridlund; Kerstin Segesten; Anna-Lena Berglund; Sylvia Määttä; Karlstads universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tactile touch; intensive care; stress; oxytocin; complementary method; nursing; preparation; randomised controlled trial; comfort; lifeworld research; narratives; Nursing; Omvårdnad; Nursing Science; Omvårdnad;

    Sammanfattning : Aim: The overall aim of this thesis was to acquire knowledge about whether tactile touch as a complementary method can (i) promote comfort and (ii) reduce stress reactions during care in an intensive care unit (ICU) Method: In Paper I, five nurses with a touch therapist training were interviewed about their experiences of preparation before giving tactile touch in an ICU. To analyse the meaning of preparation as a phenomenon, Giorgi’s descriptive phenomenological approach was used. LÄS MER

  5. 5. When children undergo radiotherapy. Exploring care, developing and testing preparation procedures

    Författare :Jenny Gårdling; Barns och familjers hälsa; []
    Nyckelord :Radiotherapy; Children; Parents; Radiotherapy nurses; Information; Preparation; Anxiety; General Anaesthesia;

    Sammanfattning : Radiotherapy (RT) is a repetitive treatment divided into daily fractions, scheduled five days a week from one up to several weeks depending upon the child’s diagnosis. Although RT is painless and non-invasive, children experience anxiety. LÄS MER
