    Abstract : Mass spectroscopy imaging (MSI) has become a vital tool in modern research due to its ability to visualize the spatial distribution of molecules within tissue samples. The collaboration between researchers at AZ, the University of Gothenburg, and Chalmers University of Technology using the NanoSIMS instrument and MSI-SIMS technology has opened up new avenues of exploration in pharmaceutical development, particularly in examining drugs and metabolites at sub-cellular levels.

  3. 2. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Franklin Lee Harris; [2023]
    Keywords : microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Abstract : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. READ MORE

  4. 3. Biogeochemistry and Peat Properties of Restored Peatlands

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

    Author : Pelle Belaieff Kronborg; [2022]
    Keywords : Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Abstract : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. READ MORE

  5. 4. Aquaculture and its effect on the wild fish resource in a Swedish lake : An evaluation of changes in fat content, protein content and trophic niche

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

    Author : Emmy Nyberg; [2022]
    Keywords : Aquaculture; wild fish; fat content; protein content; stable isotopes;

    Abstract : Fish is nutritious and important as a food source for many people. It contains high levels of protein, important omega-3 fatty acids as well as micronutrients. For a sustainable fish consumption, aquaculture is needed but it can affect nearby ecosystems in many ways. READ MORE

  6. 5. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

    Author : Frederika Klaus; [2022]
    Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE
