No causal link between terrestrial ecosystem change and methane release during the end-Triassic mass extinction

Profound changes in both marine and terrestrial biota during the end-Triassic mass extinction event and associated successive carbon cycle perturbations across the Triassic-Jurassic boundary (T-J, 201.3 Ma) have primarily been attributed to volcanic emissions from the Central Atlantic Magmatic Province and/or injection of methane. Here we present a new extended organic carbon isotope record from a

Agonist-promoted trafficking of human bradykinin receptors : Arrestin- and dynamin-independent sequestration of the B2 receptor and bradykinin in HEK293 cells

In this study, we analysed the agonist-promoted trafficking of human B2 (B2R) and B1(B1R) bradykinin (BK) receptors using wild-type and green fluorescent protein (GFP)-tagged receptors in HEK293 cells. B2R was sequestered to a major extent upon exposure to BK, as determined by the loss of cell-surface B2R using radioligand binding and by imaging of B2R-GFP using laser-scanning confocal fluorescenc

Living with pests, pets and plants: co-habitation in contemporary gardens

The private garden can be regarded as an important part of the house-owner’s home, but it is also the home of many other living organisms. Birds and mammals, insects, worms and not least plants live their lives intermingled in the contemporary human habitations of single-house suburbs. Thus, home gardens provide plenty of material to reflect on and handle biodiversity and sustainability issues in The private garden can be regarded as an important part of the house-owner's home, but it is also the home of many other living organisms.

Continuing education in neurometabolic disorders - Serine deficiency disorders

Serine deficiency disorders comprise a new group of inborn errors of serine metabolism. Patients affected with these disorders present with major neurological symptoms including congenital microcephaly, seizures, psychomotor retardation or polyneuropathy. The diagnosis of serine deficiency is based on the detection of low concentrations of the amino acids serine and glycine in fasted plasma and ce

Measuring floodplain spatial patterns using continuous surface metrics at multiple scales

Interactions between fluvial processes and floodplain ecosystems occur upon a floodplain surface that is often physically complex. Spatial patterns in floodplain topography have only recently been quantified over multiple scales, and discrepancies exist in how floodplain surfaces are perceived to be spatially organised. We measured spatial patterns in floodplain topography for pool 9 of the Upper

Floodplain complexity and surface metrics : Influences of scale and geomorphology

Many studies of fluvial geomorphology and landscape ecology examine a single river or landscape, thus lack generality, making it difficult to develop a general understanding of the linkages between landscape patterns and larger-scale driving variables. We examined the spatial complexity of eight floodplain surfaces in widely different geographic settings and determined how patterns measured at dif

Prior language knowledge and intercomprehension at the first encounter of Italian as an additional language. A translation task

The aim of the present study is to examine and describe Swedish upper secondary students’ use of their background languages while translating a text from Italian, a language unknown to them, into either their L2 English or their L3 French or Spanish. The assumption here is that searching for similarities between these languages is a natural feature of language learning and that intercomprehension

Filter Bank Design for Subband Adaptive Microphone Arrays

This paper presents a new method for the design of oversampled uniform DFT-filter banks for the special application of subband adaptive beamforming with microphone arrays. Since array applications rely on the fact that different source positions give rise to different signal delays, a beamformer alters the phase information of the signals. This in turn leads to signal degradations when perfect rec
