  1. 1. Large-Scale Land Acquisitions as a Driver of Socio-Environmental Change : From the Pixel to the Globe

    Författare :Emma Johansson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Land system sience; socio-environmental change; telecoupling; scale; co-production of knowledge; participatory art project; network science; blue and green water; Africa; Land grabbing; Remote sensing;

    Sammanfattning : A major challenge of our time is to sustainably produce food and other goods for a growing global population, without putting additional pressures on land and water resources and local people’s quality of life. Large-scale agriculture has brought many benefits to humanity in terms of food production but has also caused multiple sustainability challenges, including land and water degradation, deforestation, and biodiversity loss in areas of production.

  3. 2. From genes to blooms : Diversity in microcystin phenotypes and mcy biosynthesis genes in the cyanobacterium Microcystis

    Författare :Emma Johansson; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; limnologi; algblomning; cyanobakterier; cyanotoxiner; limnology; cyanobacterial blooms; cyanotoxins;

    Sammanfattning : Cyanobacterial blooms are increasing in occurrence and frequency world-wide, mainly due to eutrophication and increased water temperatures. In freshwater, Microcystis is one of the most common bloom-forming genera, renowned for producing the toxin microcystin which is harmful to humans and other mammals. LÄS MER

  5. 4. Eczema in childhood and adolescence

    Författare :Emma Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Eczema (atopic dermatitis) is an itchy inflammatory skin disease that affects many children and adolescents. Eczema associated with IgE antibodies is called atopic eczema (AE), while other eczema is called nonatopic eczema (non-AE). Having a filaggrin (FLG) mutation is associated with increased risk for eczema. LÄS MER

  7. 5. Nuclear Structure and Exotic Decays; Doubly-Magic 56Ni and Semi-Magic 58Ni

    Författare :Emma Johansson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Doubly magic; semi magic; 56Ni; 58Ni; high-spin states; fusion-evaporation reactions; cranked Nilsson-Strutinsky calculations; shell-model calculations; prompt proton decay; prompt alpha decay;

    Sammanfattning : The nuclear structure of two nuclei, 56Ni and 58Ni, has been studied using fusion-evaporation reaction experiments. The experiments were performed at the Lawrence Berkeley and Argonne National Laboratories in the U.S.A. LÄS MER
