  1. 11. Recycling of Blast Furnace Sludge within the Integrated Steel Plant : Potential for Complete Recycling and Influence on Operation

    Författare :Anton Andersson; Lena Sundqvist Ökvist; Hesham Ahmed; Caisa Samuelsson; Yongxiang Yang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Ore-based steelmaking generates various residues including dust, sludges, scales and slags. Internal and external recycling has allowed for 68-90 % of the dust, sludges and scales to be recycled. However, several residues are landfilled despite containing elements valuable as raw material in the production of steel. LÄS MER

  3. 12. Phytoremediation of mercury by terrestrial plants

    Författare :Yaodong Wang; Maria Greger; Lena Kautsky; Douglas Godbold; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoremediation; phytoextraction; phytostabilization; bioavailability; willow; Hg; Plant physiology; Växtfysiologi;

    Sammanfattning : Mercury (Hg) pollution is a global environmental problem. Numerous Hg-contaminated sites exist in the world and new techniques for remediation are urgently needed. LÄS MER

  4. 13. Molecular Breeding of Sugar Beet, Transformation, Transgene silencing, Virus and Herbicide resistance

    Författare :Marie Mannerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agrobacterium tumefaciens; BNYVV; coat protein; CP4epsps; gene silencing; glyphosate; herbicide; rhizomania; transformation; sugar beet; Beta vulgaris L.; virus; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The main objectives in sugar beet breeding, are to improve yield, quality and to develop disease resistance. The disease resistance may be developed either by conventional, or molecular breeding techniques. The molecular breeding techniques include, methods to genetically engineer plants for expression of introduced genes. LÄS MER

  5. 14. Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

    Författare :Lina Kristoffersen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; Djurs anatomi och morfologi; Entomologi; plant parasitology; Entomology; Ekologi; Ecology; glomeruli; antennal lobe; olfactory receptor neurons electrophysiology; antennae; behaviour; olfaction; Sternorrhyncha; psyllid; Ryggradslösa djurs fysiologi; animal morphology; Animal anatomy; växtparasitologi;

    Sammanfattning : This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. LÄS MER

  7. 15. Performance of forage maize at high latitudes : plant development, agronomy and nutritive value

    Författare :Zohaib Mussadiq; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Following the development of earlier maturing hybrids the cultivation of forage maize (Zea mays L.) in Northern Europe has markedly increased in recent decades. This has raised needs for greater knowledge regarding the performance of forage maize in marginal areas, such as Sweden, under current conditions. LÄS MER
