  1. 1. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Ellen Lundin; Lovisa Liljenberg; [2023]
    Keywords : LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE

  3. 2. Three approaches to reduce Swedish beef consumption - Effects on greenhouse gas emissions and consumer health

    University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Author : Ronja Andersson; Simon Lundin; [2016-07-01]
    Keywords : ;

    Abstract : This study estimated and compared the effect of three mitigation approaches on greenhouse gas emissions from Swedish beef consumption. In addition, we looked at the effect on the compliance with the recommended intake of red and processed meat. READ MORE

  4. 3. Removal of Arsenic in Ground Water from Northern Burkina Faso through Adsorption with Granular Ferric Hydroxide : A SIDA Minor Field Study at the Department of Chemistry, University of Ouagadougou

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Hannes Öckerman; Emma Lundin; [2013]
    Keywords : Burkina Faso; arsenic; Granular Ferric Hydroxide; adsorption; column test; drinking water; ground water; self-regeneration;

    Abstract : The need of making arsenic contaminated ground water potable is urgent in parts of Burkina Faso. An implementation of a treatment design using Granular Ferric Hydroxide (GFH) is under development. Water from a tube-well in Lilgomdé, Yatenga province, Burkina Faso, has been treated with the adsorbent GFH through column experiments. READ MORE

  5. 4. Aerosol Measurements and Analysis

    University essay from Lunds universitet/Fysiska institutionen

    Author : Maj Blomdell; Ida Lundin; [2012]
    Keywords : Aerosol particles; particle size distributions; diurnal variations.; Physics and Astronomy;

    Abstract : Abstract The greatest source of hazardous airborne particles in an urban environment comes from traffic exhaust. Air pollution has a great impact on human health; estimated to cause 1.3 million deaths worldwide per year. About half of all mortality caused by air pollution can be linked to motorized traffic.

  6. 5. Interference and Energy Conservation in Phased Antenna Arrays and Young’s Double Slit  Experiment

    University essay from Institutet för rymdfysik, Uppsalaavdelningen; Institutionen för fysik och astronomi

    Author : Andreas Lundin; [2012]
    Keywords : Interference; energy conservation; double slit; antenna; antennas; array; phased; electromagnetic coupling;

    Abstract : The interest in creating and detecting electromagnetic waves carryingangular momentum in such a way that they form helical wavefronts,so called "twisted light'', has increased in recent decades.One possible way of generating such waves at radio frequenciesis to use a circular phased antenna array, where a larger relativephasing of the antenna elements corresponds to more twist of thewavefront per wavelength.
