  1. 11. Mobility, habitat selection and population connectivity of Lycaena helle in central Sweden : implications for conservation

    University essay from SLU/Dept. of Ecology

    Author : Hanna Modin; [2018]
    Keywords : Lycaena helle; violet copper; Lepidoptera; Lycaenidae; mobility; dispersal; resource selection function; habitat selection; connectivity; metapopulation; stepping stone;

    Abstract : Lycaena helle is an endangered butterfly that is mainly threatened by habitat degradation and fragmentation. For all species with a fragmented distribution, knowledge about mobility, habitat requirements and connectivity is key to developing successful conservation strategies. READ MORE

  3. 12. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lun Sang; [2018]
    Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE

  4. 13. Closure of Lilla Bredsjön Tailings Dam : an Evaluation of the Long-Term Dam Safety Measures

    University essay from KTH/Vattendragsteknik

    Author : Jenny Bramsäter; [2017]
    Keywords : tailings dams; seepage; pore pressure; slope stability; slip surfaces; long-term stability;

    Abstract : The mining industry contributes to enormous amounts of waste all over the world, which places high demands on tailings dams. In Sweden, there are strict regulations regarding the management and treatment of tailings dams, but some dams that were built before these regulations existed still pose a threat to the environment.

  5. 14. Estimating Aquifer Transmissivity based on Streamflow Records using an Analytical Approach in Kilombero Valley, Tanzania

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Jamila Tuwa; [2016]
    Keywords : ;

    Abstract : Streamflow recession techniques have been useful in estimating aquifer hydraulic propertiesthat are not easily measured, but are important for the hydrologic responses of catchments.Compared to other hydraulic properties, aquifer transmissivity (T) is a key parameterproviding insight on groundwater development at a local and regional scale.

  6. 15. Designing and Maximizing Switch-Mode Efficiency of MODPSU, the Modular Power Supply

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Niclas Arndt; [2016]
    Keywords : DC DC; SMPS; optimization; power supply; Technology and Engineering;

    Abstract : This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. READ MORE
