1. 1. Odlingsgränsens påverkan på samhällsomvandlingen i Malmfälten

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Lotta van der Geer; [2024]
   Nyckelord :Odlingsgränsen; Samhällsomvandling; Malmfälten; Riksintresse; Rennäring; Mineral;

   Sammanfattning : This essay investigates how the transformation of society in Malmfälten is affected by thecultivation limit. The essay´s time frame is 2014 and 2018, respectively, because those are thetwo years the comprehensive plans were adopted. LÄS MER

3. 2. Procedural generation and weathering of building facades : Replicating shape and distribution of wear-and-tear on real-world building facades

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Love Wessman; [2023]
   Nyckelord :procedural modeling; building facades; wear and tear; procedurell modellering; byggnadsfasader; slitage;

   Sammanfattning : Manual modeling of building facades can be a cumbersome process. Instead, procedurally modeling building facades is a practical and quick way to achieve impressive visual results. This paper presents a method for prototyping 2D facades existing in a 3d environment, with the inclusion of shading-based procedural wear-and-tear. LÄS MER

4. 3. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Per Wahlquist; [2023]
   Nyckelord :volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

   Sammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

5. 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

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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.

7. 5. CO2 Sequestration by Bio-Accelerated Silicate Weathering

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Tora Uebel; Elisabeth Odelius; [2023]
   Nyckelord :enhanced silicate weathering; microorganisms; negative emission technology; CO2 emissions;

   Sammanfattning : Human-caused emissions of CO2 and other greenhouse gases are an established reason for the climate changes that affect planet Earth. Negative emission technologies (NETs), for example, bio-accelerated silicate weathering bioreactors, seek to capture and store carbon from the atmosphere. LÄS MER
