Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia), Boreal forest development in this region commenced by 10,000 yr B.P, Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P. Forest establishment and retrea
Swedish administrative law has not devoted much attention to the con-cepts of discretion or deference with respect to the administration. This is explained by the historically founded competence of administrative courts conducting a full review under the so-called administrative-judicial form of appeal. Here, the administrative court has the same decision-making competence as the deciding administ
This paper investigates trends in the study of Modern languages or second foreign languages (SFLs) in Swedish lower secondary school between 2000 and 2018. Over the last decades, SFLs, i.e. French, German and Spanish, have been the target of several policy measures as a response to a declining interest. However, few reports on their impact have been published. We report the proportion of pupils st
An investigation into the implementation state of open standards in software is currently ongoing through the ISPRS/EuroSDR 'GeoBIM benchmark 2019' initiative, which kicked off earlier this year. The benchmark activity provides a way of assessing and comparing the functionality of different software packages in GIS and BIM in terms of their ability to handle standardised data (IFC and CityGML) and
This study is the first to use a newly-developed material via hydrothermal method, cerium oxide nanowires doped with reduced graphene oxide (CNW-RGO) for reductive H2 production. The detailed characteristics of the CNW-RGO materials were investigated to explore the capabilities of reductive production. The mean diameter of the CNWs was uniform at 22 nm. Owing to RGO-doping, the energy gap between
Myoclonus is a hyperkinetic movement disorder characterized by brief, involuntary muscular jerks. Recognition of myoclonus and determination of the underlying aetiology remains challenging given that both acquired and genetically determined disorders have varied manifestations. The diagnostic work-up in myoclonus is often time-consuming and costly, and a definitive diagnosis is reached in only a m
Epidemiological studies on the aetiology of multiple myeloma are reviewed as a background to this population based case-control study performed in an area with a high incidence of multiple myeloma. The purpose was to identify and evaluate several suspected environmental factors in relation to this disease. A total of 275 confirmed cases diagnosed in four counties in northern Sweden during four yea
We report on the use of a sacrificial AlAs segment to enable substrate reuse for nanowire synthesis. A silicon nitride template was deposited on a p-type GaAs substrate. Then a pattern was transferred to the substrate by nanoimprint lithography and reactive ion etching. Thermal evaporation was used to define Au seed particles. Metalorganic vapour phase epitaxy was used to grow AlAs-GaAs NWs in the
The discourse of the Yemeni TV broadcasters has undergone major changes since the Arab Spring in 2011. Moreover, since the outbreak of Civil War in 2015, this discourse has been diverse and has become a clear reflection of the contexts in which it is produced. This article analyses Yemeni media discourse by analysing the titles of news reports published on YouTube by five Yemeni TV channels belong
A third of Sweden’s two million single-family houses were built in the period 1961-1980, and many of them are in need of renovation. Energy use in these houses is high, and they are fairly homogeneous in technical terms. A previous study of four reference houses showed that final energy use could be reduced in theory by approximately 65-75 % after renovation, by implementing conventional passive h
