  1. 6. 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

    Författare :Mursalin Sajib; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 7. Antimicrobial resistance of the microbiota in the reproductive tract of horses in conjunction with assisted reproduction

    Författare :Pongpreecha Malaluang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Antimicrobial resistance is a global challenge exacerbated by antibiotic misuse and inadequate infection control. This study explores the effects of antibiotics in semen extenders on the vaginal bacteria of the mare and investigates the separation of spermatozoa from bacteria in seminal plasma as an alternative to adding antibiotics to semen extenders.

  4. 8. Barriers to change? : understanding the institutional hurdles in the Russian forest sector

    Författare :Mats-Olov Olsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Statsvetenskap;

    Sammanfattning : The ongoing transformation of the Russian society largely consists in changes in the institutional framework constraining actors' behavior in the emerging market economy. While we have a substantial knowledge about the functioning of a market economy we know very little about how to create such a system. LÄS MER

  5. 9. Managing horses in groups to improve horse welfare and human safety : reactions to mixing and separation

    Författare :Elke Hartmann; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aim of this thesis was to investigate whether specific anecdotal concerns related to keeping horses in groups are supported by science and, if so, provide scientifically based recommendations that could be implemented in practice. The aim of studies I and II was to identify methods for mixing unfamiliar horses that could minimise aggressive interactions and associated risk of injury. LÄS MER

  7. 10. Chromatographic separation of wood constituents

    Författare :Niklas Westerberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; mathematical modelling.; Norway spruce; separation; chromatography;

    Sammanfattning : In a modern kraft pulp mill only about 45 % of the incoming wood is present in the pulp and it is mainly composed of cellulose. The remainder of the wood, which is dissolved in order to liberate the cellulose fibres, e.g., hemicellulose and lignin, ends up in the mill´s recovery boiler to recover the latent energy. LÄS MER
