Hierarchically Porous Silica, Carbon and Metal Oxide Monoliths – Synthesis and Characterization
(Åbo Akadem - Åbo Akademi University, 2006)Silica monoliths exhibiting a three-modal, hierarchical pore structure have successfully been prepared via sol-gel processing. Monolithic bodies with interconnected macropores in the μm range are a result of phase separation ... -
Hilbert matrix, Volterra and weighted composition operators on Banach spaces of analytic functions
(Åbo Akademi - Åbo Akademi University, 11.12.2020)Avsikten med denna avhandling är att studera två klassiska linjära integraloperatorer, Hilbertmatrisoperatorn H och den generaliserade Volterraoperatorn Tϕg mellan Banachrum av analytiska funktioner på den öppna enhetsdisken ... -
Hitting times in urn models and occupation times in one-dimensional diffusion models
(Åbo Akademi - Åbo Akademi University, 11.09.2020)The main subject of this thesis is certain functionals of Markov processes. The thesis can be said to consist of three parts. The first part concerns hitting times in urnmodels, which are Markov processes in discrete time. ... -
How computer programmers work : understanding software development in practise
TUCS Dissertations : 197 (Turku Centre for Computer Science (TUCS), 12.06.2015)Hur arbetar en framgångsrik programmerare? Uppgifterna att programmera datorspel och att programmera industriella, säkerhetskritiska system verkar tämligen olika. Genom en noggrann empirisk undersökning jämför och kontrasterar ... -
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, ... -
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 ... -
Hyperfine Interactions in Superconducting Iron-Chalcogenide and -Pnictide Compounds
(Åbo Akademi - Åbo Akademi University, 29.04.2022)This thesis deals with the synthesis and analysis of the hyperfine properties in iron-chalcogenide and -pnictide superconductors as well as related compounds. The experimental studies are based on Mössbauer spectroscopy, ... -
Identification and application of bile metabolites to assess the exposure of fish to pharmaceuticals in the environment
(Åbo Akademi - Åbo Akademi University, 26.04.2013)Thousands of tons of pharmaceuticals are consumed yearly worldwide. Due to the continuous and increasing consumption and their incomplete elimination in wastewater treatment plants (WWTP), pharmaceuticals and their metabolites ... -
Identification of Three Conserved Interaction Zones Around the Catalytic Machinery of alpha/beta- Hydrolase Fold Enzymes
(Åbo Akademi - Åbo Akademi University, 06.03.2020)The alpha/beta-Hydrolases (ABH) comprise one of the largest structural families of proteins, found in all organisms. Although they share low sequence similarity, the ABH fold enzymes maintain a common catalytic domain, the ... -
Impact of lipid-lipid interactions on lateral segregation in bilayers
(Åbo Akademi - Åbo Akademi University, 18.05.2018)The vast diversity of lipid species found in cells suggests that structural variation of lipids is essential for the normal function of the cell. One essential reason could be the formation of lateral heterogeneity in cell ... -
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 ... -
In search of information systems value : a case study of the EHR benefits realisation efforts of three Swedish hospitals.
(Åbo Akademi - Åbo Akademi University, 27.05.2014)The Swedish public health care organisation could very well be undergoing its most significant change since its specialisation during the late 19th and early 20th century. At the heart of this change is a move from using ... -
Influence of topography and surface chemistry on the wetting properties of TiO2-based ceramic coatings

Interpreting marine benthic ecosystem functioning in coastal waters: validating the biological trait concept
(Åbo Akademi - Åbo Akademi University, 21.03.2014)Coastal areas harbour high biodiversity, but are simultaneously affected by rapid degradations of species and habitats due to human interactions. Such alterations also affect the functioning of the ecosystem, which is ... -
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 ... -
Ion selective electrodes for determination of low and ultra low concentrations of lead (II) in natural waters
(Åbo Akademi - Åbo Akademi University, 14.06.2012)Monitoring natural waters for toxic components is essential for human well-being. Since the content of pollutants occurring in natural ecosystems should be kept as low as possible, there is an ongoing search for analytical ... -
Iron(III) as Lewis acid catalyst in organosilicon and carbonyl chemistry
(Åbo Akademi - Åbo Akademi University, 29.05.2015)Iron is one of the most common elements in the earth’s crust and thus its availability and economic viability far exceed that of metals commonly used in catalysis. Also the toxicity of iron is miniscule, compared to the ... -
