Multiverse Ethnography: A Qualitative Method for Gaming and Technology Use Research
2021
This article introduces multiverse ethnography as a systematic team-based qualitative method for studying the mechanical, structural and experiential properties of video games and other technological artefacts. Instead of applying the ethnographic method to produce a single in-depth account, multiverse ethnography includes multiple researchers carrying out coordinated synergetic ethnographic work on the same research object, thus producing a multiverse of interpretations and perspectives. To test the method, 41 scholars carried out a multiverse ethnography on two video games, Cyberpunk 2077 and Among Us. Explorative thematic findings regarding both titles are reported and methodological imp…
Staphylococcus epidermidis biofilmu veidošana un rezistences pret meticilīnu noteikšana, lietojot fenotipiskās un molekulāri bioloģiskās izmeklēšanas…
2018
Staphylococcus epidermidis ir veselas cilvēka ādas un gļotādas dabiskās mikrofloras sastāvdaļa, kas ir viens no visbiežāk sastopamajiem cilvēka mikrobioma pārstāvjiem. Epidermālais stafilokoks ir oportūnists, kas saimniekorganismam spēj kolonizēt gan ādu, gan gļotādu. Kaut arī S. epidermidis piemīt mazāk virulences faktoru, nekā radiniekam S. aureus, epidermālais stafilokoks ir kļuvis par vienu no visbiežāk izolētajiem koagulāzes negatīvajiem stafilokokiem intrahospitālajā vidē. Tomēr neskatoties uz to, ka epidermālajam stafilokokam ir mazāk virulences faktoru, tas ir kļuvis par nopietnu un komplicētu problēmjautājumu gan ārstniecības iestādēm, gan sabiedrības veselībai kopumā. Pētījuma mēr…
A globally relevant stock of soil nitrogen in the Yedoma permafrost domain
2022
AbstractNitrogen regulates multiple aspects of the permafrost climate feedback, including plant growth, organic matter decomposition, and the production of the potent greenhouse gas nitrous oxide. Despite its importance, current estimates of permafrost nitrogen are highly uncertain. Here, we compiled a dataset of >2000 samples to quantify nitrogen stocks in the Yedoma domain, a region with organic-rich permafrost that contains ~25% of all permafrost carbon. We estimate that the Yedoma domain contains 41.2 gigatons of nitrogen down to ~20 metre for the deepest unit, which increases the previous estimate for the entire permafrost zone by ~46%. Approximately 90% of this nitrogen (37 gigaton…
Current state and future perspectives of biochar applications in Finland
2018
Kiinnostus biohiiltä kohtaan lisääntyy jatkuvasti, sillä biohiili tarjoaa taloudellisia ja ympäristön kannalta kestäviä ratkaisuja. Biohiiltä on tutkittu Suomessa noin kymmenen vuotta, mutta vasta viime aikoina sen taloudellinen kannattavuus on tunnistettu. Aikaisemmat biohiileen liittyvät tutkimukset ovat keskittyneet lähinnä pyrolyysiprosessiin, biohiilen ominaisuuksiin sekä biohiilen potentiaalisten käyttökohteiden tutkimiseen. Biohiilen markkinatilannetta ei ole vielä Suomessa tutkittu, lukuun ottamatta biohiilen käyttöä energiantuotannossa (biohiilen poltto), mikä on kuitenkin rajattu tästä tutkimuksesta. Tämän työn tarkoitus on tutkia biohiilen käytön nykyistä tilannetta ja sen tuleva…

Chromatin structure of the 5′ flanking region of the yeastLEU2 gene
1989
The chromatin structure of theLEU2 gene and its flanks has been studied by means of nuclease digestion, both with micrococcal nuclease and DNase I. The gene is organized in an array of positioned nucleosomes. Within the promoter region, the nucleosome positioning places the regulatory sequences, putative TATA box and upstream activator sequence outside the nucleosomal cores. The tRNA3 Leu gene possesses a characteristic structure and is protected against nucleases. Most of the 5′ flank is sensitive to DNase I digestion, although no clear hypersensitive sites were found. The chromatin structure is independent of either the transcriptional state of the gene or the chromosomal or episomal loca…
Radial cracks around α-quartz inclusions in almandine: Constraints on the metamorphic history of the Oman mountains
1993
Radiating tensional cracks around α-quartz inclusions in almandine have been observed in metapelite samples from the southeastern Saih Hatat tectonic window, northeastern Oman Mountains. These almandines show an inclusion-rich (glaucophane + epidote) and strongly deformed core with inclusions of different mineral phases. The rim of the same almandines is inclusion-poor and shows only quartz, apatite, zircon, rutile and BaAl phosphates as inclusions. Quartz and apatite inclusions in the rim are single crystals often surrounded by radial cracks. These radial cracks developed during uplift by the dilation of α-quartz (4–5 vol%) without a phase transformation. Subsequently, these cracks were fi…
Influence of hydrogen cations on kinetics and equilibria of heavy-metal sorption by algae—sorption of copper cations by the alga Palmaria palmata (Li…
2013
The influence of hydrogen cations on kinetics and equilibria of sorption of copper cations by the marine alga Palmaria palmata (Linnaeus) Weber & Mohr was studied under static conditions. The competitive effect of the H+ cations is described, which influenced the uncertainty of evaluation of the alga sorption capacity. Under static conditions, the variation of the Cu2+/H+ concentration ratio during sorption was found nonmonotonic. The Langmuir isotherm model was used to determine the sorption capacity of the alga, namely 12.4 mg g−1 of dry algae mass. A similar value was determined from the kinetic parameters of the ionic exchange which is considered a pseudo-second-order chemical reaction.…
