Structural characterization of electron transfer in D.m (6-4) photolyase by time-resolved X-ray crystallography
(2022-10-18)Photolyases are flavoproteins widely spread in bacteria, archea, fungi, plants and animals. These enzymes absorb blue light and use it as an energy source for repairing damages that are induced on DNA after a prolonged ... -
The Genetics of Adaptation and Evolvability in Yeast
(2022-10-18)Evolution is the hereditary change in life forms that has shaped the divergence of all organisms that inhabit planet Earth. I used the yeast Saccharomyces cerevisiae to study how adaptive evolution increases the fitness ... -
Unravelling Mechanistic Insights of Eukaryotic Transcriptional Control
(2022-10-13)DNA transcription involves the association of multiple proteins with DNA to convert the genetic information into messenger-RNA transcripts, which later will be translated into proteins. Con-trolled regulation of transcription ... -
Impact of climate warming on Arctic plant diversity: phylogenetic diversity unravels opposing shrub responses in a warming tundra
(2022-10-13)The Arctic biome is at significant risk, with recent observations suggesting that climate change is warming the Arctic nearly four times faster than the global average. Last decade, evidence from experimental warming ... -
Alkali Release and Effects on Biomass Thermal Conversion Processes
(2022-09-19)High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, ... -
Modelling the Evolution of Species’ Ranges
(2022-09-16)The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental ... -
Thermal plasticity and limitations in tropical trees
(2022-09-12)Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate ... -
Global residue currents and the Ext functors
(2022-09-09)This thesis concerns developments in multivariable residue theory. In particular we consider global constructions of residue currents related to work by Andersson and Wulcan. In the first paper of this thesis, we consider ... -
Arsenic-induced protein aggregation and toxicity in Saccharomyces cerevisiae
(2022-08-29)Arsenic is prevalent in the environment and this toxic metalloid poses a substantial threat to human health with 100-200 million people worldwide estimated to be at risk. Chronic exposure to arsenic is associated with ... -
Wood-living beetle diversity and Swedish forest management
(2022-08-29)Humans have impacted Fennoscandian forests for thousands of years, through grazing, burning, and since the industrial revolution increasingly through efficient industrial forestry. These impacts have changed the composition ... -
On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine
(2022-08-25)Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing ... -
Oregelbundna tapetmönster: Alternativa metoder för mönsterpassning
(Hantverkslaboratoriet, Göteborgs universitet Mariestad, 2022)Syftet med studien, som genomförts som ett gästhantverkarprojekt vid Hantverkslaboratoriet, är att fördjupa kunskapen om alternativa metoder för att rapportera tapetmönster. Arbetet är också tänkt att bidra till en diskussion ... -
Time-resolved X-ray diffraction and solution scattering studies of Sensory Rhodopsin II in isolation and in complex with its transducer
(2022-05-30)Light is an important source of energy for many living organisms. Many life forms have therefore evolved cellular receptors that are able to sense light and thereby optimise conditions for photosynthesis and pho- totrophy. ... -
Äntligen i hamn - Minnen från fartygsprojektet R/V Skagerak 2012 – 2021
(University of Gothenburg / Göteborgs universitet, 2022)Skrift som sammanställts efter att Göteborgs universitets fartygsprojekt avslutats. I skriften berättar nyckelpersoner om arbetet i projektet. Tanken med skriften är att dels ge en överblick över fartyget med faktauppgifter ... -
The versatility of optical levitation
(University of Gothenburg / Göteborgs universitet, 2022)The breadth of applications of optical tweezers in life sciences is so large, that it merited Arthur Ashkin a Nobel prize in 2018. Although optical levitation in air was invented first, it has not managed to be so widely ... -
The aquatic ecotoxicity of manufactured silica nanomaterials and their interactions with organic pollutants
(2022-05-20)Manufactured silica nanomaterials are one of the nanomaterials consumed in the highest volumes (more than 4 000 000 tons/year/globally) and are used in a wide range of products and industries such as food, cosmetics, ... -
Microbial degradation of wooden foundation piles in urban context – causes and concerns
(2022-05-18)Modern infrastructural projects can endanger historical piled foundations supporting cultural heritage buildings, as groundwork can affect the subsurface environment by lowering the local groundwater level and increasing ... -
Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export
(2022-05-12)The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, ... -
Structural Dynamics of Rhodopsins using Time-Resolved X-ray Solution Scattering
(2022-05-11)Light is one of the most important sources of energy and environmental signals, and many organisms adapt in response to the presence of light. This is made possible through specialised proteins called photoreceptors. ...
