1. Decay Chains of Fast Alpha Emitters in the Actinide Region
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER
2. Public goods games for collective agri-environmental contracts design
Master-uppsats, SLU/Dept. of EconomicsSammanfattning : This thesis conducts a structured literature review of public goods games (PGG) experiments to analyze the differences between laboratory and field studies and to understand whether farmers cooperate more or less than standard PGG subjects. In addition, novel data on public goods games conducted on European farmers from Germany, Hungary, Netherlands, and Poland are analyzed to understand the effect of heterogeneous starting endowments on cooperation.

3. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER
4. Miljöfaktorers påverkan på nettoförflyttning hos mördarsnigel, Arion vulgaris
Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : The Spanish slug, Arion vulgaris, is an invasive species in Sweden and the rest of northern Europe, dispersing rapidly and widely and it has become a significant pest for both gardening enthusiasts and commercial farmers. In this study, I examined the relationship between dispersal movements and temperature, relative humidity, illuminance, and individual body mass of the slugs. LÄS MER
5. Sudetisk lärk – ett alternativ för sydsvenska skogar?
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Den svenska skogsbranschen möter betydande utmaningar med de globala klimatförändringarna som hotar framtida råvaruförsörjning. Högst troligtvis bidrar klimatförändringar till ökade stormar och en övergång till varmare och torrare förhållanden. LÄS MER
