Kristillisessä saarnassa on alkukirkosta alkaen käytetty yhteisyyttä ja erillisyyttä ilmaisevia ja aiheuttavia tekniikoita. Tarkoituksenani on tarkastella, kuinka Nokia Mission johtajan Markku Koiviston herätyssaarnoissa ja niissä edeltävissä rukouksissa luodaan ytheisyyttä ja erillisyyttä. (Abstraktin ensimäinen virke.)
Keep it rolling : Straight-line orientation in South African ball-rolling dung beetles
Representing a substantial range and variety in morphological and ecological niche, found on all continents of the globe (except for the Antarctic), the ball-rolling dung beetles provide an excellent model in which to study the heading direction network and the factors by which it is influenced. As soon as a ball-rolling dung beetle has located a fresh dung pile to feed on, it immediately starts s
Function of Innate Immune Cells in Breast Cancer
Tumor associated macrophages (TAMs) are key cells in creating an immunosuppressive tumor microenvironment (TME). In general, presence of TAMs is associated with worse outcome in cancer patients. Macrophages with anti-tumor effect can be found in the TME but are usually in minority. This thesis focuses on the role of innate immune cells, and especially macrophages, in breast cancer. In the first pr
Evaluation of the in-situ performance of neutron detectors based on EJ-426 scintillator screens for spent fuel characterization
The reliable detection of neutrons in a harsh gamma-ray environment is an important aspect of establishing non-destructive methods for the characterization of spent nuclear fuel. In this study, we present results from extended in-situ monitoring of detector systems consisting of commercially available components: EJ-426, a 6Li-enriched solid-state scintillator material sensitive to thermal neutron
BtuB-dependent infection of the T5-like Yersinia phage φr2-01
Yersinia enterocolitica is a food-borne Gram-negative pathogen responsible for several gastrointestinal disorders. Host-specific lytic bacteriophages have been increasingly used recently as an alternative or complementary treatment to combat bacterial infections, especially when antibiotics fail. Here, we describe the proteogenomic characterization and host receptor identification of the siphoviru

Detailed elemental abundances of binary stars : Searching for signatures of planet formation and atomic diffusion
Binary star systems are assumed to be co-natal and coeval, and thus to have identical chemical composition. In this work, we aim to test the hypothesis that there is a connection between observed element abundance patterns and the formation of planets using binary stars. Moreover, we also want to test how atomic diffusion might influence the observed abundance patterns. We conduct a strictly line-
Selecting accreted populations : Metallicity, elemental abundances, and ages of the Gaia-Sausage-Enceladus and Sequoia populations
Identifying stars found in the Milky Way as having formed in situ or accreted can be a complex and uncertain undertaking. We use Gaia kinematics and APOGEE elemental abundances to select stars belonging to the Gaia-Sausage-Enceladus (GSE) and Sequoia accretion events. These samples are used to characterize the GSE and Sequoia population metallicity distribution functions, elemental abundance patte
The transformation by catalysis of prebiotic chemical systems to useful biochemicals : A perspective based on ir spectroscopy of the primary chemicals: Solid-phase and water-soluble catalysts
This study is a continuation of our research on understanding the possible chemical routes to the evolution of life on earth based on the “Selective Energy Transfer” (SET) theory. This theory identifies the specific vibrational mode of the catalyst that is in energy-resonance with a suitable vibrational mode of the reactant. In this way, energy is transferred from catalyst to reactant up to the en
Model simulations of arctic biogeochemistry and permafrost extent are highly sensitive to the implemented snow scheme in LPJ-GUESS
The Arctic is warming rapidly, especially in winter, which is causing large-scale reductions in snow cover. Snow is one of the main controls on soil thermodynamics, and changes in its thickness and extent affect both permafrost thaw and soil biogeochemistry. Since soil respiration during the cold season potentially offsets carbon uptake during the growing season, it is essential to achieve a reali
Bedrock Weathering Controls on Terrestrial Carbon-Nitrogen-Climate Interactions
Anthropogenic nitrogen deposition is widely considered to increase CO2 sequestration by land plants on a global scale. Here, we demonstrate that bedrock nitrogen weathering contributes significantly more to nitrogen-carbon interactions than anthropogenic nitrogen deposition. This working hypothesis is based on the introduction of empirical results into a global biogeochemical simulation model over
The Impact of Light Pollution on Bats Varies According to Foraging Guild and Habitat Context
We Review How Different Bat Guilds Respond To Artificial Light At Night (Alan) And Assess How The Impacts Can Vary According To Ecological Context. All Studied European Species Respond Negatively To Alan Close To Roosts And Drinking Sites, And The Impacts Occur Across A Wide Range Of Light Colors And Intensities. Most Bat Species Are Sensitive To Alan When Commuting And Foraging. Although Narrow-S
Flight altitude dynamics of migrating European nightjars across regions and seasons
Avian migrants may fly at a range of altitudes, but usually concentrate near strata where a combination of flight conditions is favourable. The aerial environment can have a large impact on the performance of the migrant and is usually highly dynamic, making it beneficial for a bird to regularly check the flight conditions at alternative altitudes. We recorded the migrations between northern Europ
