The hypothetical ancestral animal the Urmetazoa: Telomerase activity in sponges [Porifera]
2003
Sponges (Porifera) represent the lowest metazoan phylum, characterized by a pronounced plasticity in the determination of cell lineages, and they are the closest related taxon to the hypothetical ancestral animal, the Urmetazoa, from which the metazoan lineages diverged. In a first approach to elucidate the molecular mechanisms controlling the switch from the cell lineage with a putative indefinite growth capacity to senescent, somatic cells, the activity of the telomerase as an indicator for immortality has been determined. The studies were performed with the marine demosponges Suberites domuncula and Geodia cydonium, in vivo with tissue but also in vitro using the primmorph system. Primmo…
The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces
2020
In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…
Counting Berg partitions via Sturmian words and substitution tilings
2013
We develop the connection of Berg partitions with special substitution tilings of two tiles. We obtain a new proof that the number of Berg partitions with a fixed connectivity matrix is equal to half of the sum of its entries, [12]. This approach together with the formula of Seebold [10], for the number of substitutions preserving a given Sturmian sequence, shows that all of the combinatorial substitutions can be realized geometrically as Berg partitions. We treat Sturmian tilings as intersection tilings of bi-partitions. Using the symmetries of bi-partitions we obtain geometrically the palindromic properties of Sturmian sequences (Theorem 3) established combinatorially by de Luca and Migno…

Oppijansuomen sähköiset tutkimusaineistot : nykytilanne
2015
[Johdanto] Korpukset tarjoavat kielentutkijoille mahdollisuuden tutkia kieltä laajojen sähköisten aineistojen avulla. Nykyisin suomen kielen tutkijoiden hyödynnettävissä on paitsi korpuksia, jotka koostuvat äidinkielisten suomenpuhujien kielestä, myös useita sellaisia korpuksia, jotka sisältäjät oppijansuomea. Maailmanjaajuisesti oppijankieliaineistot ovat yhä kasvava korpusaineistojen muoto, ja aineistoja on syntynyt runsaasti myös muista kielistä kuin englannista, joka on pitkään ollut ja on edelleenkin korpusten valtakieli.

On the adsorption and reactivity of element 114, flerovium
2022
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a volatile-metal-like character. Here, we present further experimental data on adsorption studies of Fl on silicon oxide and gold surfaces, accounting for the inhomogeneous nature of the surface, as it was used in the experiment and analyzed as part of the reported studies. We confirm that Fl is highly v…
Establishing a New ECMO Referral Center Using an ICU-Based Approach: A Feasibility and Safety Study
2022
Background: A high-volume center with a multidisciplinary team is regarded as the optimal place for providing extracorporeal membrane oxygenation (ECMO). We hypothesize that an ECMO center can also be successfully created and subsequently developed entirely by intensivists in a mid-size mixed intensive care unit (ICU). Methods: A model was created for setting up a new ECMO referral center within the structure of an existing mixed ICU in a tertiary hospital. A retrospective analysis was carried out of the first 33 patients treated in the initial period of the center’s activity, from mid 2018 to the end of 2020. Results: An ECMO center was established and developed entirely based on the resou…
The aggregation of sustainability performance measuring at company level : a case study
2015
Industrial companies face constant scrutiny about their sustainability performance development and comprehensive sustainability performance measuring is demanded from them. Companies are measuring their sustainability performance with various and multitude indicators, but it is difficult to look into the overall sustainability performance of companies based on plentiful and variable sustainability measures. There is no universally accepted method to measure the overall sustainability performance of a company, though tools for this purpose are developed. This qualitative case study research aims to shed light on whether the sustainability indicators of a case company could be aggregated in a…
