  1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Jonatan Uusitalo; [2023-08-17]
    Keywords : ;

    Abstract : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

  2. 2. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Rognås; [2023]
    Keywords : aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Abstract : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. READ MORE

  3. 3. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species

    University essay from KTH/Matematisk statistik

    Author : Elin Eliasson; Rebecka Haraldsson; [2023]
    Keywords : Phylogenetics; Tree reconstruction; COI barcoding; General Time Reversible Model; K80 Model; Evolution; Butterflies; Fylogenetik; Rekonstruktion av träd; COI barcoding; General Time Reversible modell; K80 modell; Evolution; Fjärilar;

    Abstract : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.

  4. 4. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Albin Andreasson; Noa Lind; [2023]
    Keywords : Svalbard; loess soil; XRF; weathering; climate change;

    Abstract : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

  5. 5. The CPTED principles in physical planning in Vivalla : An analysis of how safety and security can be improved through the design of urban environments in a particularly vulnerable area in Sweden

    University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Massara Sameer; Mathilda Brolin; [2023]
    Keywords : Broken Window; CPTED; Crime; Safety; Security; Situational Crime Prevention; Social sustainability; Rutin activity; Vivalla; Broken Window; Brott; CPTED; Rutinaktivitetsteorin; Situationell brottsprevention; Social hållbarhet; Säkerhet; Trygghet; Vivalla;

    Abstract : This study aims to investigate how physical planning can prevent crime and increase safety in an urban environment, with the theoretical starting point in Crime prevention through environmental design, CPTED, and the Vivalla area. Vivalla is located in Örebro and was chosen because it is a particularly vulnerable area. READ MORE
