    Sammanfattning : Education as a means to enable sustainable food consumption has gained increasing recognition as a vital means to decrease current burdens upon both natural resources and human health. In response, the Swedish compulsory school subject of home and consumer studies, which positions education about food as core content, has been revised to incorporate in its national syllabus a perspective of sustainable development since 2011.

  3. 12. Miniaturized localized surface plasmon resonance biosensors

    Författare :Si Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Sammanfattning : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

    Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER

  5. 14. Harvesting from land and sea : Social relationships, trade networks, and spatial connectivity in changing social-ecological systems

    Författare :Blanca González García-Mon; Maja Schlüter; Örjan Bodin; Emilie Lindkvist; Bonnie McCay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; social-ecological systems; food; trade; networks; embeddedness; supply chain; diversification; mobility; fisheries; agriculture; mixed-methods; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : In the era of global change, the connectivity of aquatic and terrestrial food production systems across spatial scales is increasing. At the same time, diverse actors that participate in food systems, from production to consumption, face the need to adapt their daily activities to an increasingly changing context. LÄS MER

  7. 15. Attention and Learning through the Eyes of the Emotional Brain

    Författare :Manuel Oliva; Kognitionsvetenskap; []
