The aeolian deposits of Sweden have received modest attention, despite their usefulness as a palaeoenvironmental archive. Here we present sedimentological information and optically stimulated luminescence (OSL) ages from inland sand dunes in the lowlands of south-central Sweden. Three main lithofacies, each with two subfacies, were identified in the deposits: massive sand, laminated sand and cross

First-order perturbations of homogeneous and hypersurface orthogonal locally rotationally symmetric class II cosmologies with a cosmological constant are considered in the framework of the 1+1+2 covariant decomposition of spacetime. The perturbations, which are of perfect fluid type, include general scalar, vector, and tensor modes and extend some previous works in which vorticity perturbations we

Temporal aspects of ecosystem services have gained surprisingly little attention given that ecosystem service flows are not static but change over time. We present the first systematic review to describe and establish how studies have assessed temporal patterns in supply and demand of ecosystem services. 295 studies, 2% of all studies engaging with the ecosystem service concept, considered changes

Sex chromosomes in birds have long been considered to be extremely stable. However, this notion has lately been challenged by findings of independent autosome-sex chromosome fusions within songbirds, several of which occur within a single clade, the superfamily Sylvioidea. To understand what ecological and evolutionary processes drive changes in sex chromosome systems, we need complete description

The 2030 Agenda for Sustainable Development and its seventeen Sustainable Development Goals were adopted by the United Nations General Assembly in 2015. It is a bold agenda for global social, environmental and economic development, with human health as a central theme. Even though substantial improvements in health have been achieved during the last decades, every year over 5 million children die,

Heterozygotes for major chromosomal rearrangements such as fusions and fissions are expected to display a high level of sterility due to problems during meiosis. However, some species, especially plants and animals with holocentric chromosomes, are known to tolerate chromosomal heterozygosity even for multiple rearrangements. Here, we studied male meiotic chromosome behavior in four hybrid generat

Spirocyclic acetal structures have recently received growing attention in polymer science due to their dual potential to raise the glass transition temperature (Tg) and enable chemical recycling of biobased polymers. In the present work, a vanillin-based diol with a spirocyclic acetal structure was incorporated in a series of rigid amorphous polyesters based on neopentyl glycol and dimethyl

Four organizations at Stockholm-Arlanda airport are going through various organizational changes. They are preparing for present and future demands through structural changes, implementation of new technology, training, and other efficiency and capacity improving measures. The change processes will be followed during two years of which this paper presents the baseline measurement. The key factors

Periodontal disease has been associated with atherosclerosis, suggesting that bacteria from the oral cavity may contribute to the development of atherosclerosis and cardiovascular disease. Furthermore, the gut microbiota may affect obesity, which is associated with atherosclerosis. Using qPCR, we show that bacterial DNA was present in the atherosclerotic plaque and that the amount of DNA correlate

BACKGROUND: Among the textile dyes, disperse dyes are common sensitizers. OBJECTIVE: To investigate whether patch testing with a textile dye mix consisting of eight disperse dyes would be equivalent to testing with the separate ingredients of the mix at the concentrations used in the mix. METHODS: Researchers tested 1,780 consecutive patients with a mix consisting of Disperse Blue 35, Disperse Yel

Ribosomal RNAs contain numerous modifications at specific nucleotides. Despite their evolutionary conservation, the functional role of individual 2'-O-ribose methylations in rRNA is not known. A distinct family of small nucleolar RNAs, box C/D snoRNAs, guides the methylating complex to specific rRNA sites. Using a high-resolution phenotyping approach, we characterized 20 box C/D snoRNA gene deleti

White matter (WM) changes are frequently seen on structural imaging in AD but the clinical relevance of these changes is uncertain. Frontal WM pathology is often observed upon neuropathological examination in AD. Since frontal cortical/sub-cortical pathology is known to relate to executive dysfunction, the aim was to elucidate if frontal WM changes in AD correlated with executive dysfunction. In a

Traditional chromatographic methods for the analysis of lignin-derived phenolic compounds in environmental samples are generally time consuming. In this work, an ultra-high performance supercritical fluid chromatography method with a diode array detector for the analysis of major lignin-derived phenolic compounds produced by alkaline cupric oxide oxidation was developed. In an analysis of a collec

Measuring MIMO-SAR is an important part of mobile handset evaluation, following the introduction of uplink MIMO transmission schemes in LTE-Advanced. However, the measurement of MIMO-SAR is complex and time-consuming. In this paper, 6 unique dual-antenna mobile handsets, including both typical and novel designs, are analyzed to determine the dependence of MIMO-SAR on antenna configuration and corr

Protein-peptide interactions are a common occurrence and essential for numerous cellular processes, and frequently explored in broad applications within biology, medicine, and proteomics. Therefore, understanding the molecular mechanism(s) of protein-peptide recognition, specificity, and binding interactions will be essential. In this study, we report the first detailed analysis of antibody-peptid

The common bed bug Cimex lectularius (Hemiptera; Cimicidae) is a temporary ectoparasite on humans that is currently reinvading the developed countries. Like other haematophagous arthropods, host seeking and orientation in C. lectularius is partially mediated by olfaction. In this study, we reconfirmed the distribution of the 44 olfactory sensilla and identified 3 different sensillum types located

In order to increase the understanding of how students assimilate the knowledge they need to carry out their professional duties, knowledge about the experience of the nursing education in the light of the first year of employment is important. The aim of this study was to describe nurses' views of their education, one year after their graduation. Interviews with eight nurses, aged 24 to 40 years,

White matter hyperintensities (WMH) in Mild Cognitive Impairment (MCI) have been associated with impaired executive functioning, although contradictory findings have been reported. The aim of this study was to examine whether WMH location influenced the relation between WMH and executive functioning in MCI participants (55-90 years) in the European multicenter memory-clinic-based DESCRIPA study, w

The use of Global Positioning System (GPS) technology enables the study of tourists’ activities and movement patterns in real time. But what does this information tell us about tourists’ subjective experiences? The present paper accounts for the results from four case studies: two event studies and two destination studies. Two of these took place in the wintertime, and two in the summertime. Visit
