The Arabidopsis MAP kinase 4 (MPK4) substrate MKS1 was expressed in Escherichia coli and purified, full-length, 6x histidine (His)-tagged MKS1 was phosphorylated in vitro by hemagglutinin (HA)-tagged MPK4 immuno-precipitated from plants. MKS1 phosphorylation was initially verified by electrophoresis and gel-staining with ProQ Diamond and the protein was digested by either trypsin or chymotrypsin f

Jämförelse av två flugfamiljers mångfald i två olika naturtyper Djurs mångfald är inte bara intressant utan även viktigt för att vår värld ska fungera i harmoni och kretsloppen ska slutas och gå runt. Vissa djur behövs för att bryta ned vissna växter och andra för att hålla insekters antal i schack. Några djur kan även vara tecken på om naturen mår bra eller dåligt. Olika naturtyper är hem för olBiodiversity is a big part of the understanding of our life and its surroundings. Only a fraction of the earth’s species are known and many are yet to be found. When describing new species often both molecular and morphological data is needed to fully resolve cryptic taxa. In this study, the diversity of two Diptera families, soldier flies (Stratiomyidae) and thick-headed flies (Conopidae), have b

Abstract Estuaries and salt marshes are important wetlands used by waterbirds during winter and migration. However, many salt-marshes have been transformed into salinas, which currently function as high-tide roosts. Since traditional salt production is no longer profitable, many salinas have been abandoned or converted into aquaculture potentially becoming less attractive to waders. In this study

Syfte: Syftet med studien är att med en enkätundersökning kartlägga dagliga aktivitetsmönster, välbefinnande samt olika motivationsfaktorer hos arbetssökande unga vuxna i åldern 18–25 år. Syftet är också att kartlägga vilket stöd målgruppen upplever sig ha och vilket värde ett arbete skulle ha för målgruppen. Metod: Deltagarna som medverkade var enligt exklusionskriterierna: Sjukskrivna, ej aktivtPurpose: The purpose of the study is using a survey to map daily occupational patterns, well-being, and how different motivational factors are perceived and experienced in the target group able-bodied young adults age 18–25. The purpose is also to map the support the target group have, and what values a job would have for the target group. Method The participants where picked with the exclusion cr

Direct catalytic conversion of methane to methanol offers a pathway for transforming a potent greenhouse gas into a portable clean liquid fuel, thereby mitigating carbon emissions and supporting sustainable energy. However, this process faces challenges from thermodynamically favorable methanol overoxidation. Here, we show that spatiotemporal regulation of photogenerated charge carriers on enginee

Multifunctional proteins, which play a critical role in many biological processes, have typically evolved through the recruitment of different domains that have the required functional diversity. Thus the different activities displayed by these proteins are mediated by spatially distinct domains, consistent with the specific chemical requirements of each activity. Indeed, current evolutionary theo

Succinate:quinone reductase catalyzes electron transfer from succinate to quinone in aerobic respiration. Carboxin is a specific inhibitor of this enzyme from several different organisms. We have isolated mutant strains of the bacterium Paracoccus denitrificans that are resistant to carboxin due to mutations in the succinate:quinone reductase. The mutations identify two amino acid residues, His228

Minimal Kitaev chains, composed of two quantum dots connected via a superconductor, have emerged as an attractive platform to realize Majorana bound states (MBSs). These excitations exist when the ground state is degenerate. The additional requirement of isolating the MBS wave functions further restricts the parameter space to discrete sweet spots. While scaling up to Kitaev chains with more than

Since Perestroika, Russian journalism has gone through a liberalization. However, the short lived apex of journalistic freedom that took place in the late 1980s and early 1990s was followed by a setback in particular since Putin’s accession to power in 2000. The situation for the freedom of the daily press has stagnated. Despite this, the findings based on qualitative text analysis of news article
