  1. 16. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil

    Författare :Shahin Akhlaghi; Ulf W. Gedde; Jean-Luc Gardette; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Acrylonitrile butadiene rubber; Fluoroelastomers; Biodiesel; Hydrotreated vegetable oil; Cavitation; Bound rubber; Dehydrofluorination.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. LÄS MER

  2. 17. In vitro accessibility of provitamin A carotenoids in vegetables and fruits - Effects of different process and preparation methods and estimation of vitamin A activity

    Författare :Ellen Hedrén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; provitamin A carotenoids; lactic acid fermentation; food matrix; cell wall degrading enzymes; vegetables; vitamin A activity; beta-carotene; red palm oil; fruits;

    Sammanfattning : Vitamin A deficiency is a major nutritional problem in many developing countries, caused chiefly by a diet with low retinol content. The bioefficacy of provitamin A carotenoids in plant foods is claimed to be insufficient to maintain a satisfactory vitamin A status. LÄS MER

  3. 18. Lipids in seeds of oat (Avena spp.), a potential oil crop : content, quality, metabolism, and possibilities for improvement

    Författare :Svetlana Leonova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : New oil crops with high yield and oil content are urgently needed. Oat is the only cereal that accumulates substantial amount of lipids in the endosperm. This gives it potential as an oil crop, which could address both nutritional and environmental concerns of modern society. LÄS MER

  4. 19. Comparative study of residue pellets from cane sugar and palm-oil industries with commercial wood pellets, applied in downdraft gasification

    Författare :Catharina Erlich; Torsten Fransson; Björn Zethraeus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy engineering; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning : While biomass utilization for energy conversion in the industrialized nations is being largely developed, highly efficient and environmentally friendly, many tropical countries still use biomass at low efficiencies and high emission levels. The main reasons for these gaps are both political and technological: the energy markets are different, the Gross National Product (GDP) differs widely, and the feedstock differs in form and conversion behaviour.

  5. 20. Evaluation of an automatic urinometer including use of silicone oil to decrease biofilm formation due to proteinuria, hemoglobinuria and bacterial growth

    Författare :Martin Slettengren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: A new capacitance-based automatic urinometer (AU) facilitates continuous urine output (UO) measurement, which may help to predict and diagnose acute kidney injury (AKI). To prevent mismeasurement due to bacterial, albumin or free hemoglobin biofilm, a water-soluble capsule with silicone oil has been integrated in the device. LÄS MER
