On the mathematics of the one-dimensional Hegselmann-Krause model
(2022-01-19)This thesis contains three papers, which all in different ways concern the asymptotics of the Hegselmann-Krause model in opinion dynamics. In this model a set of conformist agents repeatedly and synchronously replace their ... -
Mixing and Evaporation at the Cloud Edge and Angular Dynamics of Small Crystals in Viscous Flow
(2022-01-19)How liquid water in atmospheric clouds distributes over droplets of different sizes is important for the initiation of rainfall, and for the optical properties of the atmosphere. Droplet-number densities and droplet-size ... -
Nutrient dynamics in coastal and shelf oceans - sediments as a regulator of eutrophication feedbacks
(2022-01-10)Coastal and shelf systems are under increasing pressure from human activities. Many coastal systems currently suffer from excessive algae growth following increased nutrient input from land, a process called eutrophication. ... -
Exciton coupling and energy transfer in perylene-based systems
(2022-01-07)Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and ... -
Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models
(2022-01-07)Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain ... -
Mellan himmel och rum. Kunskapsläget om medeltida taklag i svenska kyrkor 2020.
(Hantverkslaboratoriet, Göteborgs universitet/Västergötlands museum/Svenska kyrkan, 2021-12-22)I denna rapport görs ett försök att översiktligt sammanfatta den kunskap vi genom de senaste tio årens inventeringsprojekt fått om Sveriges äldsta bevarade träkonstruktioner, de medeltida taklagen i våra kyrkor. Resultaten av ... -
The Structural Modularity and Inherent Dynamics of the DegP Protease together with its Intertwined Role in the Bacterial Periplasm
(2021-12-09)The protein quality control machinery is a delicate and integrated network of molecular tools working together to fold or remove unwanted proteins from the cell. A distinct set of “gatekeepers” are involved in this process ... -
Cardiorespiratory function of euryhaline teleosts - Regulatory mechanisms, effects of warming and costs of osmoregulation
(2021-11-26)Teleost fishes have colonized almost every aquatic habitat on earth and exhibit adaptations that allow them to thrive in environments with very diverse physico-chemical properties. One fundamental environmental variable ... -
Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation
(2021-11-25)Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the ... -
Nitrogen Losses from a Clay-rich Soil used for Cereal Production in south-western Sweden
(2021-11-24)Addition of fertiliser nitrogen (N) in crop production increases yields and protein contents, but all is not taken up by the crop. Instead, some of the N is lost to air and waters, contributing e.g. to climate change, ... -
Ample Rare Elements: A Geochemical Anomaly in the Earth's Crust at Norra Kärr
(2021-11-18)The Norra Kärr alkaline complex in southern Sweden (58°06’N, 14°34’E) is a classic occurrence of agpaitic rocks, which contains a large mineral deposit of rare-earth elements (REE), Zr, and Nb. The complex consists of ... -

Havsis längs svenska västkusten
(University of Gothenburg / Göteborgs universitet, 2021)Det är något alldeles speciellt med is, som många som åker skridskor på våra vinterisar vet. Årets möjlighet att få åka på havet längs den svenska västkusten väckte både sprudlande glädje och osäkerhet inför havsisen. -
Frequency comb Brillouin microscopy
(2021-10-26)Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied ... -
Painting Treatments of Weather-Exposed Ferrous Heritage. Exploration of Oil Varnish Paints and Painting Skills
(2021-10-15)This thesis is about industrial heritage—the protection of ferrous heritage by using anticorrosive oil varnish paints. The purpose of this thesis in Kulturvård and craft research is to provide guidelines, tools, concepts, ... -
Development and Applications of Microfluidic Devices for Liver-on-a-Chip Studies
(2021-10-12)Modeling the human physiology in vitro is a challenging task, yet one of importance for the development of drugs and the study of diseases. To better address the complexities of human organs, microfluidic systems called ... -
The molecular chaperone CCT: Functions beyond folding
(2021-10-07)The chaperonin-containing tailless complex polypeptide 1 (CCT) is a eukaryotic ~1 MDa barrel shaped molecular chaperone, built up by eight distinct subunits and is required for the folding of the abundant cytoskeletal ... -
Effects of carbon dioxide and ozone on wheat crop yield and grain quality
(2021-10-05)Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, ... -
