  1. 1. Det mesolitiska Västmanland - ett landskapsperspektiv

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Erika Andersson; [2024]
    Nyckelord :ecology; landscape; Middle Stone Age; resources; Scandinavia; spatial analysis; spatial distribution;

    Sammanfattning : The Mesolithic period in Sweden lasted generally between 9500-4000 BC and is characterised by the dynamic landscape. People usually lived in smaller groups by the coast, sustained by the forests and the sea’s resources. The study is limited to central Sweden, specifically the province of Västmanland. LÄS MER

  3. 2. Quantification of Pharmaceuticals at the sub-cellular level using the NanoSIMS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk kemi

    Författare :Maryam Dost; [2024]
    Nyckelord :Mass spectroscopy imaging; AstraZeneca; Nanosims; Therapeutics; pharmacokinetics; pharmacodynamics; Quantitative Visualization; calibration curve; RSF; pharmacology; Data Analysis; Chemistry; Quantification; isotopes; Pharmaceuticals; subcellular; drug; drug target; nucleotide; biodistribution; Bioanalytical electrochemistry; spectroscopy; mass spectrometry; analytical separations; Analytical Chemistry; ROI; Bioanalytical Chemistry; Masspektroskopi avbildning; AstraZeneca; Nanosims; Terapeutik; farmakokinetik; farmakodynamik; Kvantitativ visualisering; kalibreringskurva; RSF; farmakologi; Dataanalys; Kemi; Kvantifiering; isotoper; Läkemedel; subcellulär; läkemedel; läkemedelsmål; bioskopisk elektrofördelning; nukleotid; bioskopisk bioskopisk distribution; masspektrometri; analytiska separationer; analytisk kemi; bioanalytisk kemi;

    Sammanfattning : 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.

  4. 3. Quantum Optical Description of High-order Harmonic Generation

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

    Författare :Isabel Moreno; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  5. 4. Incorporation of climate effects in marine spatial planning. Possible Climate Refugia on the Swedish West Coast Based on Two Climate Scenarios

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Eric Strömberg; [2023-08-11]
    Nyckelord :Climate Refugia; Climate Change; Representative Concentration Patterns; Marine Spatial Planning; Geographical Information Systems; Temperature; Salinity; Marine Management; Swedish West Coast;

    Sammanfattning : Climate change poses a significant threat to the survival and distribution of marine species and habitats. Identification and conservation of climate refugia have emerged as a strategy to safeguard vulnerable habitats and promote species resilience. LÄS MER

  7. 5. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Melissa Miranda; [2023-06-30]
    Nyckelord :Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Sammanfattning : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.
