  1. 1. Effect of Touch on Cotton and Maize : influence on plant morphology and feeding preference in Spodoptera littoralis

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Anna Magnusson; [2022]
    Keywords : Mechanical stimuli; cotton; maize; thigmomorphogenesis; Spodoptera littoralis; induced defence; plant-plant interaction;

    Abstract : Plants are constantly exposed to touch and mechanical stimuli in natural environments, from rain, wind, animals and plant neighbours. However, current knowledge and understanding of how touch physiologically affects plants are limited. READ MORE

  3. 2. Blue biotechnology : its role in the future of food

    University essay from SLU/Department of Molecular Sciences

    Author : Andrea Lundh; [2020]
    Keywords : Aquaculture; blue biotechnology; aquatic resources; SDG; sustainable development goals; blue growth; zero hunger; food security; agenda 2030;

    Abstract : To provide healthy food and livelihoods to a growing population on Earth, while environmental issues becoming more adverse, as well as climate change becoming more critical, is one of today’s greatest challenges. By 2015 the United Nations come up with 17 Sustainable Development Goals (SDG’s) to tackle global challenges as poverty, global hunger, climate resilience, population growth control, achieving food security, and promotion of sustainable agriculture.

  5. 4. Cross-Country Faults in Resonant-Earthed Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gabriel Miguel Gomes Guerreiro; [2020]
    Keywords : Cross- country fault; resonant earthing; compensated network; MV network; distance protection; fault analysis; RTDS EMTDC.; dubbla jordfel; spoljordning; jordfelskompenserade elnät; mellanspänningsnät; distansskydd; reläskydd; RTDS EMTDC.;

    Abstract : Reliability requirements for power systems have been constantly increasing, as customers of electric power desire high power availability. In order to improve continuity of supply in medium voltage (MV) networks, utilities in many countries in Europe, North/South America and Oceania use resonant earthing and allow the operation of the network during a single phasetoearth fault for periods from several seconds up to several hours, since the earthfault current at the fault point in such systems is considerably reduced and is unlikely to damage equipment or create hazardous voltages for people or livestock.
