    Keywords : 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.;

    Abstract : 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. READ MORE

  4. 2. Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes

    Author : Janne Paavilainen; Chris Bales; Jan-Olof Dalenbäck; Lennart Gustavsson; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flue gas; measurement; characterization; averaging Pitot tube; SolNET;

    Abstract : Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. READ MORE

  6. 4. Occupational exposure to polycyclic aromatic hydrocarbons and early biomarkers related to cardiovascular disease and cancer

    Author : Ayman Alhamdow; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Polycyclic aromatic hydrocarbons (PAH) are omnipresent environmental pollutants composed of fused benzene rings and mainly produced by incomplete combustion of organic material. PAH exposure has been associated with increased risk of cancer and probably cardiovascular disease (CVD). READ MORE

  7. 5. The air distribution in buildings with combined natural and mechanical ventilation

    Author : Gunnar Åhlander; KTH; []
    Keywords : ;

    Abstract : This work describes result from both measurements on anumber of one family houses, an analytical study of a one-zonemodel and multi zone studies of a two storey building. Thesimulations are performed as both parametric studies, withcombined values of outside temperature, wind velocity and winddirection, and whole year simulations. READ MORE
