  1. 1. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Francesca Polato; [2021]
    Keywords : hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Abstract : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

  3. 2. Visualizing and Controlling Coupling Paths Between Antennas Installed on Common Platforms

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

    Author : Johan Lundgren; [2020]
    Keywords : ;

    Abstract : In this work, a methodology to visualize and mitigate antenna coupling ina systematic way is proposed, which can be used to increase the isolationbetween dierent antenna systems installed on a common platform. Formulationsfor visualizing the coupling in space, based on reciprocity are derivedfrom the reaction theorem and the dierent formulations are compared witheach other through numerical simulations in CST Microwave Studio and bypost-processing in Matlab.

  4. 3. Development of a method for preparing alpaca semen by colloid centrifugation

    University essay from SLU/Dept. of Clinical Sciences

    Author : Sofia Karlsson Warring; [2019]
    Keywords : alpaca semen; single layer centrifugation; colloid; motility; artificial insemination.;

    Abstract : Alpacas belong to the South American Camelids and they share many characteristics with other camelids. The camelids have unique reproductive characteristics; one example of that is the high viscosity of their semen. READ MORE

  5. 4. Balancing use and conservation in marine spatial planning - Perspectives of sustainability and the ecosystem approach in a Swedish context

    University essay from Göteborgs universitet / Institutionen för ekonomi och samhälle

    Author : Julia Sandberg; [2018-03-13]
    Keywords : marine spatial planning; the Ecosystem Approach; sustainable development;

    Abstract : The environmental concern and interest in marine resources are growing, which is reflected within marine policies in the European Union. In 2007 the Integrated Maritime Policy (IMP) was adopted, aiming at collecting and integrating marine policies in one framework. READ MORE

  6. 5. Evaluation of sustainability criteria for small-scale wastewater treatment facilities

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Edvard Nordenskjöld; [2017]
    Keywords : On-site sewage facilities; phosphorus; micropollutants; multi-criteria analysis; precipitation; adsorption; full-scale; wastewater treatment; Enskilda avlopp; fosfor; mikroföroreningar; multi-kriterie analys; utfällning; adsorption; fullskala; avloppsrening;

    Abstract : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. READ MORE
