  1. 1. Techno-economic analysis of large-scale production of e-methanol, via CO2- hydrogenation, in Power-to-X

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Jonathan Ahlbäck Ikonen; [2023]
    Keywords : Power-to-X; E-methanol; Hydrogen Production; CO2-hydrogenation; Methanol Synthesis; Decarbonisation; Chemical Engineering; Technology and Engineering;

    Abstract : Global levels of carbon emissions are constantly rising causing irreversible damages to ecosystems. The heavy transport sector and the industrial sector are responsible for large amounts of the emissions on a yearly basis. READ MORE

  3. 2. Design without Nature : reflektioner kring naturbaserade lösningar med Ekostaden Augustenborg som exempel

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

    Author : Erik Rydiander; [2022]
    Keywords : Naturbaserade lösningar; Ekostaden Augustenborg; Robert L. Thayer; Topofili; Teknofili; Teknofobi; Ideala Landskap; Reella Landskap; Dissonans;

    Abstract : Intresset för naturbaserade lösningar ökar och de bedöms vara ett viktigt verktyg för att möta samtidens och framtidens samhällsutmaningar, så som global uppvärmning, massutdöende av arter, kollapsande ekosystem, m.m. En central idé med naturbaserade lösningar är att de ser till naturen som en förebild för bra lösningar. READ MORE

  4. 3. The role of diseases in mass mortality of wood lemmings (Myopus schisticolor)

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Henrik Johansen; [2021]
    Keywords : wood lemming; Myopus schisticolor; disease; virus; pathogens; mass mortality; orthohantavirus; pan-orthohantavirus; somatic index; spleen index;

    Abstract : Like many other rodent species, the wood lemming (Myopus schisticolor) exhibits cycles with large population peaks but unlike most other European rodents, these peaks are frequently followed by mass mortality. It is largely unknown what pathogens wood lemmings carry and if pathogens could affect their population dynamics. READ MORE

  5. 4. Assessing the biodiversity crisis within the Triassic-Jurassic boundary interval using redox sensitive trace metals and stable carbon isotope geochemistry

    University essay from Lunds universitet/Geologiska institutionen

    Author : Halla Margrét Viðarsdóttir; [2020]
    Keywords : Stenlille; Schandelah; redox conditions; C-isotopes; marine sediments; trace elements; enrichment factors; mass extinction; Triassic – Jurassic boundary; Earth and Environmental Sciences;

    Abstract : Around the Triassic-Jurassic-Boundary time interval, a severe mass extinction event occurred, which has been associated to volcanism of the Central Atlantic Magmatic Province (CAMP). Significant amounts of greenhouse gases as carbon dioxide (CO2) or methane (CH4) and other volatiles are suggested to have been released into the atmosphere, leading to global warming with subsequent impact on the biosphere.

  6. 5. Hotade djurarter i trädgårdar och parker : bevarande av biologisk mångfald

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

    Author : Moa Berg; [2019]
    Keywords : biologisk mångfald; habitatdegradering; park; trädgård; rödlista; djurarter; habitat;

    Abstract : Mänsklighetens utveckling har lett till att den biologiska mångfalden är hotad. Städer expanderar på bekostnad av omgivande landskap och alla arter som lever där. På grund av detta fragmenteras, förändras och förstörs många djurarters habitat och gör att populationerna försvagas eller till och med dör ut. READ MORE
