Quantitative analysis of tumor growth and response to therapy
(2010-01-14)Modeling the natural growth of tumors is of value for evaluation of tumor progression and optimization of treatment strategies. However, modeling tumor growth based on clinical data is hampered by the limited data available, ... -
Quantitative chemical imaging to study content release from single nanovesicles
(2023-12-05)Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, ... -
Quantitative NanoSIMS provides subcellular concentration and distribution of oligonucleotide therapeutics
(2023-04-28)Antisense oligonucleotides (ASOs) represent a powerful therapeutic modality that can selectively modulate gene expression. However, ASOs face two major hurdles that restrict their use in the clinic. The first issue is ... -
Quantum dynamical effects in complex chemical systems
(2020-05-12)When using mathematical models to computationally investigate a chemical system it is important that the methods used are accurate enough to account for the relevant properties of the system and at the same time simple ... -
Quantum Force in Wigner Space
(2014-04-08)In this thesis, I will present effective methods to study quantum dynamics using trajec- tories. Our methods are based on a method named the Classical Wigner model which starts with a quantum initial condition and generates ... -
Rainfall variability, soils and land use changes in the Ethiopian highlands
(2013-09-16)Most farmers in the Ethiopian highlands are dependent on rain-fed agriculture. The indigenous cereal tef is the most important crop for the farmers in the highlands. The central highland is an environmentally fragile area ... -
Regional and local surface ozone variations in relation to meteorological conditions in Sweden
(2009-05-07)Air quality is strongly dependent on meteorological conditions. Atmospheric circulation encapsulates general information about local meteorological variables to some extent, and can serve as an explanatory variable for ... -
Regionala timmertraditioner - workshop oktober 2014
(Hantverkslaboratoriet, 2015)Timmermännen Björn Frost, Dalarna, Tommy Nyberg, Norrbotten, Daniel Åkerman, Hälsingland och Karl Magnus Melin, Skåne, timrar varsin regional knut på en workshop i Mariestad. Projektledare: Göran Andersson. Arkitekt: Anna ... -
Regulation and transport mechanisms of eukaryotic aquaporins
(2013-01-11)Aquaporins are found in all kingdoms of life where they are involved in water homeostasis. They are small transmembrane water conducting channels that belong to the ancient protein family Major Intrinsic Proteins (MIP). ... -
Regulation of electron donation to photosystem 1
(2011-05-09)Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions ... -
Regulators of Membrane Fluidity
(2020-04-29)Caenorhabditis elegans PAQR-2 (a homolog of the mammalian AdipoR1 and AdipoR2 proteins) and IGLR-2 (homolog of the mammalian LRIG proteins) form a complex at the plasma membrane that regulates fatty acid desaturation to ... -
Relationships between nomenclature, phylogenetics and systematics
(2008-09-01)Systematists have become increasingly aware of the limits imposed by the current system of nomenclature for accurately representing evolutionary relationships and managing efficiently names associated with clades. In ... -
Reproductive Biology and Population Genetics of Common Ash (Fraxinus excelsior L.)
(2011-03-17)Common Ash, Fraxinus excelsior L. (Oleaceae) is a wind-pollinated, wind-dispersed, deciduous tree, commonly occurring throughout Central and Northern Europe. The thesis addresses several questions concerning reproductive ... -
Reproductive isolation at contact zones
(2021-01-18)Speciation is among the most important evolutionary processes that contribute to biodiversity. It involves the formation of new species that have become reproductively isolated through a process that is not linear and ... -
Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions
(2020-03-24)Organisms are adapted to reproduce in their specific environment by a range of different traits. For many animals, reproduction is tied to specific conditions, that trigger or enable the reproductive events. This thesis ... -
Resampling in network modeling of high-dimensional genomic data
(University of Gothenburg and Chalmers University of Technology, 2017)Network modeling is an effective approach for the interpretation of high-dimensional data sets for which a sparse dependence structure can be assumed. Genomic data is a challenging and important example. In genomics, ... -
Responses of shallow sediment ecosystems to environmental alterations
(2013-02-14)Shallow-water sediment systems are continuously exposed to a range of anthropogenic stressors, including increased nutrient loading, physical disturbance and toxicants. Superimposed on these local stressors are stressors ... -
Restaurering av ett jordkällarvalv
(Hantverkslaboratoriet, Göteborgs universitet, 2014)Många jordkällare i Sverige har valv av natursten. Att lägga ett sådant valv kräver kännedom om material och arbetssätt. I den här filmen får vi se Sten Nilsson restaurera ett skadat naturstensvalv. Filmat vid ett ... -
Restoration and management of eelgrass (Zostera marina) on the west coast of Sweden
(2016-11-11)Since the 1980s over 60% of eelgrass (Zostera marina) habitats have been lost from the Swedish NW coast, resulting in significant losses of the valuable ecosystem services provided by these habitats. The eelgrass loss has ...
