Exploring magnetocaloric materials by ab-initio methods
(Åbo Akademi University & Uppsala University, 26.04.2024)This thesis explores the characterization of magnetocaloric materials from first-principles calculations, emphasizing entropy variation associated with the magnetocaloric effect. The study happens in the context of the ... -
Bioimage Analysis for Life Scientists : Tools for Live Cell Imaging
(Åbo Akademi - Åbo Akademi University, 26.04.2024)Live imaging is essential in visualizing biological processes such as normal tissue development, wound healing, and cancer — processes too small for the bare human eye to observe. Optical microscopy has enabled the ... -
Implications of the Integration of a Non-Native Fish into Coastal Communities
(Åbo Akademi - Åbo Akademi University, 14.03.2024)The Baltic Sea ecosystem is undergoing unprecedented changes in abiotic conditions due to the combined effects of climate change, eutrophication, and bottom-water deoxygenation. Non-native species, introduced outside their ... -
Modulation spectroscopies for characterization of photovoltaic materials and devices
(Åbo Akademi - Åbo Akademi University, 08.03.2024) -
Human Ecosystem Engineering : Effects and Feedback in Coastal Benthic Systems
(Åbo Akademi - Åbo Akademi University, 16.02.2024)In the attempt to enhance their environment, humans are causing changes in ecosystems worldwide, by acting as ecosystem engineers. Changes in ecosystems, caused by any ecosystem engineering species, have the potential to ... -
Contract-Based Design of Dataflow Programs
(Åbo Akademi - Åbo Akademi University, 19.01.2024)Quality and correctness are becoming increasingly important aspects of software development, as our reliance on software systems in everyday life continues to increase. Highly complex software systems are today found in ... -
The impact of dissolution products and solution pH on in vitro behaviour of the bioactive glasses 45S5 and S53P4
(Åbo Akademi - Åbo Akademi University, 19.01.2024)Glass is a versatile material used in our everyday life. The chemical durability of glass depends on its composition. Some applications benefit from lower chemical durability. Glasses in a narrow compositional range are ... -
Breeding during a Predation Regime Shift : Behavioural and physiological responses of female common eiders facing the recovery of their native predator
(Åbo Akademi University & CNRS–La Rochelle Université, 14.12.2023)Predation is a key selective force driving prey trait evolution. Yet, the extent to which predator-consumptive and predation risk effects shape phenotypes is still poorly understood. Since predation risk increases the cost ... -
Regulation of Inflammatory Signalling by Caspases and M1-linked Ubiquitin Chains in Drosophila melanogaster
(Åbo Akademi - Åbo Akademi University, 30.11.2023)The NF-κB family of transcription factors are master regulators of innate immune responses and their dysregulation can lead to chronic inflammation and cause diseases like inflammatory bowel disease and cancer. To treat ... -
HSF1 and HSF2 in Stress and EMT-Associated Transcriptional Networks
(Åbo Akademi - Åbo Akademi University, 15.09.2023)Protein-damaging stress frequently occurs during the lifetime of a cell. To survive these insults, cells rely on the action of proteins called transcription factors that adjust the expression of genes, such as chaperones, ... -
Regulation of Death Receptor Responses by Hyperthermia
(Åbo Akademi - Åbo Akademi University, 01.06.2007)Cells need a variety of responses to protect themselves against stresses caused by changes in the environment. Likewise, a complex apoptotic machinery is necessary for elimination of cells that are no longer needed in the ... -
Energy Aware Runtime Systems for Elastic Stream Processing Platforms
(Åbo Akademi - Åbo Akademi University, 22.08.2023)Following an invariant growth in the required computational performance of processors, the multicore revolution started around 20 years ago. This revolution was mainly an answer to power dissipation constraints restricting ... -
Utilizing κ-carrageenan Hydrogels in Teaching, Outreach and Chemical Gardens
(Åbo Akademi - Åbo Akademi University, 04.08.2023)κ-carrageenan is a biopolymer that can be extracted from red seaweeds and has found great use for example in the food industry due to its excellent gelling, thickening and stabilizing abilities. The work done in this thesis ... -
Calcium Signaling in Cell Compartments - the Importance of Sphingosine Kinase 1 and ORP5/8
(Åbo Akademi - Åbo Akademi University, 21.06.2023)För att upprätthålla liv använder cellerna i en organism intrikata signaleringsräckor för regleringen av fysiologiska processer inom enskilda celler och mellan olika celler och vävnaderna som utgör en organism. Reglering ... -
Intertwining Cell Adhesion, Gene Expression, and Stress
(Åbo Akademi - Åbo Akademi University, 01.06.2023)Cells within an organism are constantly exposed to environmental insults that challenge the homeostasis of their proteome by causing protein misfolding. To survive these adverse situations, cells are equipped with a ... -
Different Types of Weighted Composition Operators on Banach Spaces of Analytic Functions
(Åbo Akademi - Åbo Akademi University, 26.05.2023)Many problems in real life are, at least approximatively, of linear nature and can be mathematically examined with the aid of linear spaces. It is natural to measure the size of objects occurring in the problems and such ... -
Laboratory Studies on Aqueous Absorption and High Temperature Chemistry of NOx and SOx in Thermal Conversion of Biomass Waste
(Åbo Akademi - Åbo Akademi University, 05.05.2023)In order to fulfill the transition to a climate neutral economy and society, various renewable energy sources are needed to replace fossil fuels. Thermal conversion of biomass waste streams plays an important role in this ... -
Pristine iota-Carrageenan and Chemically Functionalized Guar gum Polysaccharides for Metal-ion Complexation and CuS-based Nanocomposite Preparation
(Åbo Akademi - Åbo Akademi University, 19.04.2023)Natural polysaccharides are ubiquitous in nature and have been widely used in human history as food, materials, fuels, and medicine. To cope with climate crisis and develop a more sustainable economy, promoting the use of ... -
The Role of Vimentin in Tissue Repair and Cell Growth
(Åbo Akademi - Åbo Akademi University, 10.03.2023)Microfilaments, microtubules, and intermediate filaments serve as the cytoskeleton of the cell and form a complex network by interacting with cytoskeleton-associated proteins. The cytoskeleton provides a framework for the ... -
