  4. 2. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

    Author : Mursalin Sajib; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; separation; silage; pilot-scale; lipid oxidation; Herring Clupea harengus ; protein hydrolysis; ensilaging; antioxidants; fish oil; valorization; by-products;

    Abstract : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. READ MORE

  5. 3. Hydrothermal Liquefaction of Lignin into Bio-Oil

    Author : Huyen Nguyen Lyckeskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrothermal conversion; aging; bio-oil; stability; subcritical water; lignin;

    Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Nowadays, most of the lignin (almost 99%) produced in the Kraft pulping process is used as internal fuel. READ MORE

  6. 4. Natural products from Bolivian plants and other sources

    Author : Marcelo Bascope; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Organic chemistry; Organisk kemi; Plant biochemistry; Bolivian plants; ESIMS oxygen adducts; Myrothecium roridum; Silphion persicum; Cyathea boliviana; Rheedia acuminata; Heliconia episcopalis; Iryanthera juruensis; Aniba canelilla; Natural products;

    Abstract : The present research was focused on the phytochemical research of Bolivian plants; a) two medicinal ones Aniba canelilla and Iryanthera juruensis, both plants showed to have compounds with biological activity in different fields. Even though Aniba canelilla was studied before, new compounds were identified in this investigation. READ MORE

  7. 5. Parameters affecting the functionality of additives in lubricated contacts : effect of base oil polarity

    Author : Aldara Naveira Suarez; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Traditionally rolling contact fatigue observed in bearing field applications was subsurface initiated. However, despite the improvement of steel properties, some factors such as downsizing in bearing design, extreme loading of the bearings as well as demanding application conditions (start up-stop cycles) have led to an increase on the cases of surface damage related to surface initiated fatigue, that comes basically from surface distress.
