    Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

  3. 2. Evaluation of a Gradient Free and a Gradient Based Optimization Algorithm for Industrial Beverage Pasteurisation Described by Different Modeling Variants

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Lea Miko Versbach; [2016]
    Nyckelord :numerical optimization; pasteurization; modeling; food engineering; derivate free; Mathematics and Statistics;

    Sammanfattning : Inspired by Krones Group in Holte/Copenhagen, the intention of this thesis is to simulate and optimize pasteurisation processes. Based on different modes of heat transfer, a mathematical model to describe the thermal processes in the product is developed. The main goal of the thesis is to optimize the thermal treatment of the product. LÄS MER

  4. 3. A method for water disinfection with solar pasteurisation for rural areas of Bangladesh

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Erika Lundgren; [2014]
    Nyckelord :Solar water pasteurisation; surface water; semi-permanent device; solar radiation; Bangladesh.;

    Sammanfattning : In order to improve the water situation in rural areas of Bangladesh, a research group at the University of Dhaka has been developing low cost domestic methods to remove pathogens from surface water through pasteurisation using free solar energy. Pasteurisation is a process in which water is heated to approximately 60 °C and maintained for about 30 minutes to destroy pathogens. LÄS MER

  5. 4. En jämförelse mellan amplifierad singelmolekylanalys och selektiv agar vid kontroll av hygienisering av avloppsslam

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Julia Fransson; [2011]
    Nyckelord :amplifierad singelmolekylanalys; avloppsslam; Salmonella; hygienisering;

    Sammanfattning : Bringing back the nutrients from the city to the country is becoming increasingly important, as the world’s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. LÄS MER

  7. 5. Development of a Technical, Economical and Environmental Sustainable Solar Oven Technology – A Field Study in Sri Lanka

    Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Jesper Danielsson; Johannes Elamzon; [2008]
    Nyckelord :Solar oven system; Cooking; Water pasteurisation; Sri Lanka;

    Sammanfattning : Large environmental, health, social and economical problems are connected with the use of fossil fuels and, in a dominating part of the world, also the use of firewood. The goal for this project was to develop and design an optimal solar oven system intended for food cooking and water pasteurisation. LÄS MER
