  1. 1. Bio-based materials from crambe and carinata industrial oilseed meals : compression moulded and extruded oilseed meal plastics

    Author : William Newson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Protein-based plastics are considered as a new route for valorisation of oilseed meal from the industrial oil crops Crambe abyssinia (crambe) and Brassica carinata (carinata) as they cannot be used for animal feed or human food. To convert oilseed meals into protein-based plastic films compression moulding was used with varying processing temperature, chemical additives and protein extraction conditions. READ MORE

  2. 2. Gene silencing mechanisms in Phytophthora infestans

    Author : Vetukuri Ramesh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The hemibiotrophic oomycete, Phytophthora infestans, causes late blight on potato and tomato. This destructive pathogen is well known for the rapidity with which it overcomes host resistance. This thesis focuses on the molecular basis of gene (RNA) silencing in P. infestans and the role it may have in its genome biology and pathogenesis. READ MORE

  3. 3. Molecular genetics and mechanisms of pigmentation and melanoma

    Author : Elisabeth Sundström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Ever since man domesticated the first wild animals several thousand years ago, many species have been living in close relationship with humans, being objects for our requests and wishes about any kind of phenotypic traits. As a result, we have by selective breeding created a fascinating spectrum of phenotypes within most species we have domesticated. READ MORE

  4. 4. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

    Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

    Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

  5. 5. Understanding of molecular mechanisms and improving of adventitous root formation in apple

    Author : Anders Smolka; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Adventitious root formation is essential for vegetative propagation, which is the main method for propagation of many horticultural crops, especially woody species. For propagation of apple rootstocks, adventitious root formation is often a limiting step. READ MORE
