Facilitation and Feedbacks in Seagrass Communities : Testing the Role and Context-Dependency of Ecosystem Engineers
(Åbo Akademi - Åbo Akademi University, 18.12.2020)In physically unstable habitats such as coastal soft sediments, facilitative interactions are essential for structuring associated ecological communities. Here, habitat amelioration by ecosystem engineers such as seagrasses, ... -
Cellular regulation of the Notch signaling pathway by Notch-interacting proteins
(Åbo Akademi University, 25.09.2020)The Notch signaling mechanism is a crucial regulator of stem cells during development and tissue regeneration. Transcriptional activation of Notch target genes requires cleavage of the Notch receptor in response to ligand ... -
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. ... -
Explicit results in theory of zeros and prime numbers
(Åbo Akademi - Åbo Akademi University, 28.08.2020)This thesis is comprised of three articles in which we prove explicit estimates for different number theoretical problems.In the first article we derive an explicit Riemann-von Mangoldt formula for the Selberg class ... -
Target Controllability of Cancer Networks
(Åbo Akademi University, 12.06.2020)Advances in the field of complex networks theory and network biology pave a new way to define human health through the study of networks of proteins, genes, metabolites, modules across cell signaling pathways, and clinical ... -
Coastal Habitats and their Importance for the Biodiversity of Faunal Communities
(Åbo Akademi - Åbo Akademi University, 24.06.2020)Coastal habitats represent highly productive areas serving important functions for multiple organism groups. These shallow areas generally maintain high faunal biodiversity, providing important ecosystem goods and services, ... -
Zoobenthos as indicators of marine habitats in the northern Baltic Sea
(Åbo Akademi University, 05.06.2020)Zoobenthos are beneficial indicators of habitat quality and environmental stress and change due to their longevity and how they react species-specifically to abiotic factors. This PhD, consisting of four published papers, ... -
Drivers of plankton populations in the Baltic Sea
(Åbo Akademi University, 20.05.2020)Plankton are at the base of the food chain, and identifying their drivers is important for understanding how climate change will impact populations and communities. The main aim of my thesis was to quantify the effects of ... -

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 ... -
Formal Model Refinement for Complex Biological Systems
(Åbo Akademi - Åbo Akademi University, 20.03.2020)There is a big interest in building large biological models and various approaches are being used for constructing such systems. Larger models are needed in system-level approaches (such as systems biology, systems medicine, ... -
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 ... -
Regulation of Notch Signaling by Intracellular Trafficking
(Åbo Akademi - Åbo Akademi University, 21.02.2020)The Notch signaling pathway is one of the essential mediators of cell-cell communication during development of multicellular organisms. Notch signaling is based on receptors and ligands that interact between neighboring ... -
Nanoparticles as Targeting System for Cancer Treatment : From idea towards reality
(Åbo Akademi - Åbo Akademi University, 20.09.2019)To be able to target cells of interest is one of the key aims in medicine today, because it could minimize side effects of drugs. This is of special importance in cancer therapies, were the treatment has serious side-effects ... -
A Compiler Approach to Map Algebra for Raster Spatial Modeling
TUCS Dissertations : 243 (Turku Centre for Computer Science (TUCS), 30.08.2019)Modeling and simulation enables the study of spatial phenomena that are otherwise impossible to reproduce in the physical world.
