  1. 26. Depression and cognition in the elderly : neuroimaging perspective

    Författare :Aleksandra Lebedeva; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis examines the relationship between depression and brain structure in the elderly with (Study I, III) and without (Study II, IV) cognitive impairment (Alzheimer’s disease and mild cognitive impairment). Individuals from four independent cohorts were included. LÄS MER

  3. 27. Group 11–14 Triazenides : Synthesis, characterization, and thermal evaluation for use in chemical vapor deposition

    Författare :Rouzbeh Samii; Henrik Pedersen; Nathan O´brien; Andrew Johnson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Chemical vapor deposition (CVD) and atomic layer deposition (ALD) are corner-stone techniques for depositing thin films in semi-conductor manufacturing. To deposit semiconductor grade materials, these techniques rely on high-performance precursors. LÄS MER

  4. 28. Epitaxy, analysis and application of semi-insulating III-V materials

    Författare :David Söderström; KTH; []
    Nyckelord :InP; GaInP; semi-insulating materials; iron doping; ruthenium doping; HVPE; diffusion; deep levels; capture cross sections; resistivity analysis; buried heterostructure laser;

    Sammanfattning : Semi-insulating (SI) III-V materials can provide electricalisolation for integration and capacitance minimisation for highspeed operation. Compared to the polyimides, these can offerbetter thermal conduction. Ever since the fabrication of thefirst SI III-V materials, transition metals have been utilisedas deep impurities to impart SI properties. LÄS MER

  5. 29. High-entropy boron-carbide and its composites

    Författare :Hanzhu Zhang; Farid Akhtar; Peizhong Feng; Yong Zhang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : High-entropy alloy (HEA) is a multicomponent alloy material that contains five or more principal elements in equi- or near equi-atomic ratios. The entropy stabilisation leads to the formation of a crystalline solid solution accommodating the principal elements. LÄS MER

  7. 30. Predictors of Outcome after Anterior Cruciate Ligament Reconstruction

    Författare :Eric Hamrin Senorski; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; ACL; reconstruction; physcial therapy; concomitant injury; knee; predictors; outcome;

    Sammanfattning : An anterior cruciate ligament (ACL) injury is one of the most common injuries to the knee joint. It is also one of the most researched areas within sports medicine, orthopedics and physical therapy. LÄS MER
