  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 2. Trädplantering i den hårdgjorda staden : utmaningar och lösningsalternativ

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Ingela Carlgren; [2024]
    Keywords : gatuträd; urbana träd; trädplantering; gatumiljö; urban jord; kompaktering; skelettjord; makadamsubstrat; rotceller; suspended pavement;

    Abstract : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. READ MORE

  4. 3. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy

    University essay from

    Author : Umair Ali Khan; Soroosh Zahedi; [2023-09-14T08:42:05Z 2023-09-14T08:42:05Z 2023 2023]
    Keywords : Corrosion resistance; Fatigue; Aluminium alloys; HPDC; PMC; Sheet Metal; Anodization Molding; Casting;

    Abstract : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. READ MORE

  5. 4. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Erik Svensson; [2023]
    Keywords : HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Abstract : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. READ MORE

  6. 5. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jonas Fahlman; [2023]
    Keywords : astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Abstract : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.
