  1. 1. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Philippe Simon; [2023]
    Nyckelord :Ley production; Nitrogen fixation; Pollination ecology;

    Sammanfattning : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). LÄS MER

  3. 2. Nodulation and biomass development of yellow and blue lucerne under pH stress

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Katarina Boström; [2023]
    Nyckelord :lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Sammanfattning : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. LÄS MER

  4. 3. Swedish red clover-associated Rhizobium leguminosarum bv. trifolii share high genetic similarity in the 16S gene but divergence in nod genes

    Master-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Tua Lilja; [2023]
    Nyckelord :genetics; nitrogen fixation; sustainability; symbiosis; taxonomy;

    Sammanfattning : Rhizobium leguminosarum biovar trifolii (Rlt) is a root-associated soil bacterium (rhizobia) capable of entering a symbiotic relationship with various species of clover (Trifolium sp.) and fix nitrogen within root nodules. LÄS MER

  5. 4. Talk to the Sea: Deep-sea mining, the arts, and contesting narratives of extraction in the deep ocean.

    Master-uppsats, Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Författare :Nicholas Frederick Olivier Lepage; [2023]
    Nyckelord :deep-sea mining; resource frontier; commodities; arts; extractivism; narratives; imaginaries.; Social Sciences;

    Sammanfattning : The deep-sea may be on the verge of becoming the latest frontier for resource extraction of critical metals and minerals in order to build renewable energy technologies such as electric vehicles. This thesis examines the narratives used by the deep-sea mining company The Metals Company to justify the extraction of polymetallic nodules from the seabed in the Clarion Clipperton Zone in the Pacific Ocean.

  7. 5. Ultralågdosprotokolls tillförlitlighet vid detektion av lungnoduli : Allmän litteraturöversikt

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Boonsri Karboo; Siri Willner; [2023]
    Nyckelord :datortomografi; lungnoduli; medicinsk bildkvalité; röntgensjuksköterska; tumördetektion; ULD-CT;

    Sammanfattning : Introduktion: Computed Tomography (CT) är en effektiv och snabb undersökningsmetod. Den visar detaljrika bilder men har en relativt hög stråldos som kan orsaka skador på grund av upprepade undersökningar, till exempel leda till lungcancer. Därför är reducering av stråldos prioriterat inom radiologin. LÄS MER
