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

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

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

    Sammanfattning : 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. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  4. 3. Hur avrinningskoefficienten varierar med återkomsttid - En jämförelse mellan fyra olika områden i Sverige

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Nina Enger; [2024]
    Nyckelord :Runoff coefficient; Return period; Modelling; MIKE ; Floodings; Technology and Engineering;

    Sammanfattning : As climate change progresses, heavy rainfall in Sweden is becoming more frequent and intense, coinciding with an increase in impermeable surfaces in urban areas. This raises the risk of flooding as drainage networks may exceed their capacity due to increased runoff. LÄS MER

  5. 4. Optimization of concrete recipe made with crushed aggregate

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jonathan Lindekrantz; Pontus Axelsson; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. LÄS MER

  7. 5. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    Master-uppsats, KTH/Kemi

    Författare :Ran Carlhamn Rasmussen; [2023]
    Nyckelord :VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Sammanfattning : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. LÄS MER
