The Ordovician of Scandinavia: a revised regional stage classification

The Ordovician of Scandinavia (i.e. Denmark, Norway and Sweden) has been investigated for over two centuries and, through time, various chronostratigraphic schemes have been introduced, facilitating regional correlation. However, a modern chronostratigraphy has never been proposed. Here, we delineate ten regional stages for the Ordovician of Scandinavia, comprising, in ascending order, the Slemmes

Perceived global accent in Turkish heritage speakers in Germany : The impact of exposure and use for early bilinguals

This chapter is concerned with Turkish heritage speakers (HSs) in Germany, here exemplified by 21 early bilinguals during adulthood who live in Hamburg, North Germany. We introduce the population, report their self-perceived proficiency and propose the Turkish Use Score (TUS) that is based on quantitative aspects of language use (e.g., the number of people Turkish is spoken with) and qualitative o

Formal Linguistics and Language Education : Bridging the Gap

In this chapter, we provide a brief introduction to recent work in linguistics that has its origin and motivation in formal linguistics and theoretical acquisition research, and on this basis indicates potential connections and contributions to language pedagogy, including students’ and teachers’ beliefs about what ‘grammar’ actually is.

X-BASE the first terrestrial carbon and water flux products from an extended data-driven scaling framework, FLUXCOM-X

Mapping in situ eddy covariance measurements of terrestrial land–atmosphere fluxes to the globe is a key method for diagnosing the Earth system from a data-driven perspective. We describe the first global products (called X-BASE) from a newly implemented upscaling framework, FLUXCOM-X, representing an advancement from the previous generation of FLUXCOM products in terms of flexibility and technica

Eddy covariance measurements reveal a decreased carbon sequestration strength 2010–2022 in an African semiarid savanna

Monitoring the changes of ecosystem functioning is pivotal for understanding the global carbon cycle. Despite its size and contribution to the global carbon cycle, Africa is largely understudied in regard to ongoing changes of its ecosystem functioning and their responses to climate change. One of the reasons is the lack of long-term in situ data. Here, we use eddy covariance to quantify the net e

SoilTemp : A global database of near-surface temperature

Current analyses and predictions of spatially explicit patterns and processes in ecology most often rely on climate data interpolated from standardized weather stations. This interpolated climate data represents long-term average thermal conditions at coarse spatial resolutions only. Hence, many climate-forcing factors that operate at fine spatiotemporal resolutions are overlooked. This is particu

Satellite-based estimations of coniferous forest cover changes : Krusne Hory, Czech Republic 1972-1989

The extent and rate of deforestation from 1972 to 1989, including some spatial properties in the heavily polluted mountains of Krusne Hory, on the border between the Czech Republic and Germany were studied. Deforestation was assessed using satellite remote sensing integrated with digital elevation data. The results show that over 50% of the coniferous forest disappeared during this period. Especia

Samband mellan Landsat TM-data och skoglig produktivitet i sodra Sverige

A regression was established according to Wald's method for the estimation of forest productivity in the study area. A correlation of 0.58 was found between productivity (m3sk/ha/year) and TM4/TM3. The 198 compartments which were included in the study were divided into four groups on basis of their productivity. The correlation between observed productivity and estimated productivity was 0.59. The

Sevuparin strongly reduces hepcidin expression in cells, mice, and healthy human volunteers

Hepcidin is an essential regulator of systemic iron availability mediating both iron uptake from the diet and its release from body stores. Abnormally high hepcidin levels resulting from inflammation in chronic diseases cause iron restriction with the onset of anemia. Restoring physiological levels of hepcidin could contribute to ameliorating anemia in these patients. Heparin derivatives are known

Using an integrated motor imagery and physical training intervention after knee injury : An interim analysis of the MOTIFS randomised controlled trial

Objectives Physical function is often a main focus of knee injury rehabilitation, but recent recommendations include increasing attention to psychological factors. We have developed the MOTor Imagery to Facilitate Sensorimotor re-learning (MOTIFS) training model which integrates dynamic motor imagery into physical rehabilitation. The objective is to report interim analysis results of an adaptive r

Evaluation of Au(III) complexes as Plasmodium falciparum aquaglyceroporin (PfAQP) inhibitors by in silico and in vitro methods

The onset of resistance to artemisinin for malaria treatment has stimulated the quest for novel antimalarial drugs. Herein, the gold(III) coordination complexes Aubipy [Au(bipy)Cl]+ (bipy = 2,2'-bipyridine), Auphen [Au(phen)Cl]+ (phen = phenanthroline), Auterpy [Au(terpy)Cl]2+ (terpy = 2,2';6',2″-terpyridine), and corresponding hydrolyzed species, have been investigated as inhibitors of the Plasmo
