  1. 6. Determinants of outcome in lumbar spinal stenosis surgery

    Author : Freyr Gauti Sigmundsson; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lumbar spinal stenosis; outcome; pain; function; health related quality of life; decompression; spinal fusion;

    Abstract : Lumbar spinal stenosis (LSS) is a degenerative disorder of the spine that predominantly affects the elderly. LSS is the most common spinal disorder leading to surgery in Sweden. Recent randomized controlled studies have showed better outcome with surgery compared to conservative treatment. READ MORE

  2. 7. Offshore deployments of marine energy converters

    Author : Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
    Keywords : offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

    Abstract : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. READ MORE

  3. 8. Optimizing computed tomography : quality assurance, radiation dose and contrast media

    Author : Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). READ MORE

  4. 9. Bloody big data : ensuring the health of blood donors and transfused patients with health registers

    Author : Jingcheng Zhao; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Blood transfusion is widely considered a pillar of modern medicine and is one of the most common medical interventions. A transfusion intimately links two persons and their health through the altruism of blood donors. In turn, this has necessitated the development of rigorous safety measures for both donors and recipients. READ MORE

  5. 10. Vertical Heterostructure III-V MOSFETs for CMOS, RF and Memory Applications

    Author : Adam Jönsson; Nanoelektronik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; CMOS; RRAM; III-V; InAs; GaSb; InGaAs; Heterostructure; vertical; nanowire NW ; MOSFET; III-V materials; RRAM; RF; CMOS; InAs; GaSb; InGaAs; heterostructure; Vertical nanowire;

    Abstract : This thesis focuses mainly on the co-integration of vertical nanowiren-type InAs and p-type GaSb MOSFETs on Si (Paper I & II), whereMOVPE grown vertical InAs-GaSb heterostructure nanowires areused for realizing monolithically integrated and co-processed all-III-V CMOS.Utilizing a bottom-up approach based on MOVPE grown nanowires enablesdesign flexibilities, such as in-situ doping and heterostructure formation,which serves to reduce the amount of mask steps during fabrication.
