  1. 1. 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. 2. Analysis of pervasive climate risks to global rice production at the subnational level

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Qian Mei; [2023]
    Keywords : ;

    Abstract : Rice is a vital crop and main source of calories for half the global population, particularly in the GlobalSouth. Despite increasing demand for rice, climate change, urbanisation, and land use development arethreatening rice production and therefore food security. READ MORE

  4. 3. Using blue light reflectance from high-resolution images (6000 dpi) of Scots pine tree rings to reconstruct three centuries of Scottish summer temperatures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Alice De Schutter; Karin Markendahl; [2021]
    Keywords : summer temperature reconstruction; climate change; Scotland; Scots pines; ultra-high image resolution; blue intensity; rekonstruktion av sommartemperatur; klimatförändringar; Skottland; skotska tallar; hög bildupplösning; blå intensitet;

    Abstract : Advances in scanner technology have made it possible to obtain high resolution (6000 dpi) images of tree samples. Due to the images’ increased capability of resolving anatomical wood structures, the new technology could be of benefit to dendroclimatology.  This study attempts to expand on Rydval et al.

  5. 4. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Andersson; [2021]
    Keywords : geochemistry; loess; XRF; weathering; climate change; N-W France;

    Abstract : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. READ MORE

  6. 5. Analysis of Paperboard Performance using Digital Image Correlation

    University essay from KTH/Hållfasthetslära

    Author : Yiming Liang; [2020]
    Keywords : Paperboard; Digital image correlation; Comparable stages; Compensation; Kartong; Digital bildkorrelation; Jämförbara tillstånd; Kompensation;

    Abstract : The performance of paperboard materials in packaging application has been investigated and evaluated for a long time. This is because it plays a decisive role for product protection and decoration in packaging applications. Potential damages during transportation sometimes affect the consistency of the performance.
