    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum nitride; reactive sputtering; c-axis oriented films; tilted films; electroacoustic devices; piezoelectric materials; Aluminum Scandium Nitride; HiPIMS; high-k dielectric; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : The requirements of the consumer market on high frequency devices have been more and more demanding over the last decades. Thus, a continuing enhancement of the devices’ performance is required in order to meet these demands. In a macro view, changing the design of the device can result in an improvement of its performance. LÄS MER

  3. 2. Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence

    Författare :Jacob Engellau; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; growth pattern; time-dependence; P-glycoprotein Pgp ; CD44; β-catenin; cyclin A; bcl-2; p53; Ki-67; immunohistochemistry IHC ; whole-tumor sections; tissue microarray TMA ; Soft tissue sarcoma; prognostic factors; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : In adult soft tissue sarcoma (STS) of the extremities and trunk wall, improved prognostic factors are needed to identify patients at high-risk for metastasis. Various factors are included in the many prognostic systems currently in use and the prognostic value of immunohistochemical (IHC) expression of biological markers is unclear. LÄS MER

  4. 3. Glaucoma Diagnostics

    Författare :Sabina Andersson; Oftalmologi (Malmö); []
    Nyckelord :POAG – glaucoma – diagnostic accuracy – screening – subjective assessment – population-based – GDx VCC – OCT – HRT – FDT – ONH assessment – CME – ANN – artificial neural network – visual field assessment;

    Sammanfattning : This thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice.

  5. 4. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta

    Författare :Adel BinJabr; Vaskulära sjukdomar - kliniska studier; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chimney stent graft; chimney graft; chimney graft technique; snorkel technique; endovascular aortic repair; thoracic endovascular aortic repair; endoleak; patency; rupture; urgent; stent-graft; stent; graft; aorta; computed tomography; ultrasound; stenosis; EVAR; TEVAR; CTA; MRI; AAA; TAAA; supraaortic; visceral; aneurysm; dissection; mycotic infection; stent-graft infection; follow-up; endovascular complication; sandwich technique; periscope graft; periscope graft technique.;

    Sammanfattning : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. LÄS MER
