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
Planted Forests Greened 7% Slower Than Natural Forests in Southern China Over the Past Forty Years
Forests have seen a strong greening trend worldwide, and previous studies have attributed this mainly to land-use conversions such as afforestation. However, for the greening of existing forests, the role of human interventions is unclear. Here we paired neighboring natural and planted forests in Southern China to minimize the differences between the forest types and analyzed the vegetation index
Understanding the superconductivity and charge density wave interaction through quasi-static lattice fluctuations
In unconventional superconductors, coupled charge and lattice degrees of freedom can manifest in ordered phases of matter that are intertwined. In the cuprate family, fluctuating short-range charge correlations can coalesce into a longer-range charge density wave (CDW) order which is thought to intertwine with superconductivity, yet the nature of the interaction is still poorly understood. Here, b
Temperature modulates the tuning properties of small target motion detector neurons in the dragonfly visual system
Dragonflies are poikilothermic animals with limited thermoregulation; therefore, their entire bodies, including the brain, experience a range of temperatures during their daily activities.1,2 These flying insects exhibit hunting prowess, pursuing prey or conspecifics whether in direct sunlight or under the cover of cloud.3,4 Likely to underlie these aerobatic feats are the small target motion dete
Biological degradation of organic micropollutants in GAC filters–temporal development and spatial variations
The capacity for organic micropollutant removal in granular activated carbon (GAC) filters for wastewater treatment changes over time. These changes are in general attributed to changes in adsorption, but may in some cases also be affected by biological degradation. Knowledge on the degradation of organic micropollutants, however, is scarce. In this work, the degradation of micropollutants in seve
Co-Digestion and Mono-Digestion of Sewage Sludge and Steam-Pretreated Winter Wheat Straw in Continuous Stirred-Tank Reactors—Nutrient Composition and Process Performance
Wheat straw (WS) constitutes a considerable biomass resource and can be used to produce the energy carrier methane through anaerobic digestion. Due to the low contents of several nutrient elements and water in harvested WS, the use of sewage sludge (SS), consisting of primary sludge and waste-activated sludge, as a nutrient source in co-digestion with steam-pretreated wheat straw (PWS) was investi
Application of infrared reflection microspectroscopy for chemical imaging of cross-sectioned urinary calculi
We used infrared reflection microspectroscopy for chemical imaging of urinary calculi and showed that contribution of diffuse reflection, influencing the imaging results, can be suppressed by decreasing surface roughness and (or) increasing wavelength of infrared radiation applied for the imaging.
