  1. 16. A Study on Endoscopic Live Donor Nephrectomy and Elevated Intraperitoneal Pressure

    Författare :Pernilla Lindström; Bengt Rippe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Candesartan; cardiac output; glomerular filtration rate; hand-assisted laparoscopy; hand-assisted retroperitoneoscopy; kidney; living donor nephrectomy; morbidity; pneumoperitoneum; rat; renal transplantation; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Live donor nephrectomy (LDN) is a unique surgical challenge where surgery is performed on healthy individuals. It is of great importance to keep the morbidity of donors as low as possible, as well as harvesting a kidney in optimal condition. Lowering morbidity is the motive for introducing the endoscopic technique in LDN. LÄS MER

  3. 17. Preparation and Evaluation of New Nanoporous Silica Materials for Molecular Filtration and for Core Materials in Vacuum Insulation Panels

    Författare :Ebenezer Twumasi Afriyie; Folke Björk; Christer Sjöström; Kjartan Gudmundsson; Per Jostein Hovde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorbents; activated carbon; MgCa-silica; carbon-silica composite; characterization; porous parameters; molecular filtration; thermal conductivity; thermal insulation;

    Sammanfattning : Nanoporous materials for gas purification and thermal insulation have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Further the utilization of nanoporous material as thermal insulator in building applications is limited due to high cost. LÄS MER

  4. 18. Bleeding and Filtration of Cement-Based Grout

    Författare :Almir Draganovic; Håkan Stille; Ulf Lindblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building manufacturing engineering; Byggproduktionsteknik;

    Sammanfattning : Grouting is a common method of sealing rock around tunnels to reduce or stop water inflow. Successful grouting significantly minimizes the maintenance cost and safety of the tunnel. Some questions about bleeding and penetrability of the grouts have to be examined more closely to carry out a successful grouting. LÄS MER

  5. 19. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release

    Författare :Johan Sällström; Erik Persson; Peter Hansell; Jürgen Schnermann; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. LÄS MER
