    Sammanfattning : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. LÄS MER

  4. 3. Microstructure of Cermets

    Författare :Per Lindahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermodynamic; microchemistry; N ; AP-FIM; Ti C; cutting tools; SEM; cemented carbide; TEM; sintering;

    Sammanfattning : The microstructure of several TiC-TiN-Mo2C-WC-Co/Ni model alloys and a commercial (Ti,Ta,W,Mo)(C,N)-(Co,Ni) type cermet was studied using x-ray diffraction, optical microscopy, scanning electron microscopy, analytical electron microscopy and atom probe field ion microscopy. In addition thermodynamical calculations were made in order to understand the development of the microstructure during sintering. LÄS MER

  5. 4. Möten mellan människor och teknologi : berättelser från intensivvårdssjuksköterskor och personer som ventilatorbehandlas i hemmet

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nursing; critical care nursing; home mechanical ventilation; ventilator; home-nursing-professional; home health care; spiritual care; advocacy; testimony; qualitative-studies; phenomenological hermeneutics; Omvårdnad; Nursing; Omvårdnad; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : The overall aim of this thesis is to illuminate meanings of the relation between human beings, technology and care, as narrated by critical care nurses and people in need of home mechanical ventilation (HMV). The data are based on narrative research interviews with six intensive care nurses (I), 13 people who were about to start HMV (II), these 13 people were interviewed for a second time six to eight months after HMV had started (III), and nine persons with more than two years HMV experience (IV).
