Aim: The dominant role of Tilia in primeval forests of Scandinavia has long been recognized, but the timing and mechanisms for its decline have not been completely unravelled. A particular uncertainty involves the balance between climate and human activities as the drivers of the change. One reason for the uncertainty is the challenge in evaluating the past cover of the genus owing to its poorly d

Sweden, with a high level of political participation and an avant-garde position regarding internet access, broadband and social media penetration in the population, is a critical case for studying social media in relation to political participation. Three types of users – members of political parties, members of interest organizations, and non-members – are interviewed in focus groups about their

The c-kit-encoded tyrosine kinase receptor for stem cell factor (Kit/SCFR) is crucial for the development of hematopoietic cells, melanoblasts, and germ cells. Ligand stimulation of Kit/SCFR leads to receptor dimerization and autophosphorylation on tyrosine residues. We recently showed, that protein kinase C (PKC) acts in an SCF-stimulated negative feedback loop, which controls Kit/SCFR tyrosine k

Electrification of energy demand is seen as one of the key elements of energy transition toward decarbonisation. E-mobility is one main side of the electrification process, and it is considered as a crucial way to reduce the emissions of the transport sector. A core element for a widespread adoption of electric vehicles (EVs) is the deployment of the charging infrastructure, and installing a micro

The game industry has continued to grow for decades and the social interaction trend has been growing for years in gaming. In retail, the e-commerce companies have been extending the social interaction trend to the e-commerce platforms and turning the e-commerce into social commerce. Even though the social commerce and gaming have aroused the interest of the researchers earlier, social commerce in

Formerly widely distributed throughout Europe, the great snipe (Gallinago media) – a medium-sized wader species – has experienced an important decline in the last century, mainly driven by habitat loss. Remaining population are now restricted to eastern Europe and Scandinavia and the species is considered endangered. The great snipe (Gallinago media) is a food specialist, feeding almost exclusivel

Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int

Background: The involvement of aquaporin (AQP) water and small solute channels in the etiology of several diseases, including cancer, neuromyelitis optica and body fluid imbalance disorders, has been suggested previously. Furthermore, results obtained in a mouse model suggested that AQP9 function contributes to hyperglycemia in type-2 diabetes. In addition, the physiological role of several AQP fa

Photoluminescence (PL) of organo-metal halide perovskite semiconductors can be enhanced by several orders of magnitude by exposure to visible light. We applied PL microscopy and super-resolution optical imaging to investigate this phenomenon with spatial resolution better than 10 nm using films of CH3NH3PbI3 prepared by the equimolar solution-deposition method, resulting in crystals of different s

In northern peatlands the thawing of permafrost increasing the active layer depth and changing the hydrology may lead to feedbacks in the climate system through changes in the biogeochemistry of carbon. We are examining this association on the Stordalen peatland complex in subarctic Sweden by analyzing a DEM derived from LiDAR-data and the calculated TWI. The DEM, with a spatial resolution of 1 m,
