Photofragmentation of argon clusters of average size ranging from 10 up to 1000 atoms is studied using soft x-ray radiation below the 2p threshold and multicoincidence mass spectroscopy technique. For small clusters (N=10), ionization induces fast fragmentation with neutral emission imparting a large amount of energy. While the primary dissociation takes place on a picosecond time scale, the fragm
Different lifetime broadenings in molecular-field-split 2p core levels in H2S are predicted theoretically and are identified in an experimental investigation of the S 2p Auger electron spectrum. The measurements were performed for the transition to the vibrationally resolved X(1)A(1) ground state of H2S2+. The lifetimes of the 3e(1/2) and 5e(1/2) levels of the 2p ionized molecule are found to be 6
We investigated whether ghrelin depletion (by gastrectomy surgery) and/or treatment/replacement with the gastric hormone ghrelin alters the expression of key hypothalamic genes involved in energy balance, in a manner consistent with ghrelin's pro-obesity effects. At 2 weeks after surgery mice were treated with ghrelin (12 nmol/mouse/day, sc) or vehicle for 8 weeks. Gastrectomy had little effect on
The paper analyses the legal framework for the collection and distribution of remote sensing data, particularly in the field of sustainable development and environmental protection at the European level. The research firstly focuses on the historical evolution of space law at the international, European, and national levels, starting from the 1970s. In parallel, environmental law has rapidly devel
Motivated by the well established idea that collective wisdom is greater than that of an individual, we propose a novel learning dynamics as a sort of companion to the Abelson model of opinion dynamics. Agents are assumed to make independent guesses about the true state of the world after which they engage in opinion exchange leading to consensus. We investigate the problem of finding the optimal
BACKGROUND: The plant microbiome represents one of the key determinants of plant health and productivity by providing a plethora of functional capacities such as access to low-abundance nutrients, suppression of phytopathogens, and resistance to biotic and/or abiotic stressors. However, a robust understanding of the structural composition of the bacterial microbiome present in different plant micr
Plesiosaurs are an iconic group of Mesozoic marine reptiles with an evolutionary history spanning over 140 million years (Ma).1 Their skeletal remains have been discovered worldwide; however, accompanying fossilized soft tissues are exceptionally rare.2 Here, we report a virtually complete plesiosaur from the Lower Jurassic (∼183 Ma)3 Posidonia Shale of Germany that preserves skin traces from arou
INTRODUCTION: Hospital-acquired bloodstream infections (HA-BSIs) are severe and require antibiotic therapy. In non-complicated BSIs, shortened therapy reduces side effects without compromising efficacy. The impact of shortened antibiotic therapy in HA-BSI critically ill patients without indication of prolonged therapy requires further evaluation. METHODS: Using the international prospective EUROBA
I artikeln görs en översikt över jordbrukets och skogsbrukets närvaro i konsten i Sverige under 1900-talet. Den innehåller också analyser och diskussioner rörande hur, när och varför det agrara motivet är närvarande alternativt frånvarande i konsten under perioden.
A major concern for contemporary organizations is how to gain support of business processes from standardized software package such as enterprise resource planning (ERP) systems. To gain support adoption of such standardized information and communication technologies (ICTs) demands that either the system is adjusted to existing business processes or that business processes are adjusted to the syst
Background: When compared to the other mismatch repair genes involved in Lynch syndrome, the identification of mutations within PMS2 has been limited (<2% of all identified mutations), yet the immunohistochemical analysis of tumour samples indicates that approximately 5% of Lynch syndrome cases are caused by PMS2. This disparity is primarily due to complications in the study of this gene caused by
Background Rheumatoid arthritis (RA) and osteoarthritis (OA) are important musculoskeletal diseases that the EUMUSC.NET project developed Standards of Care (SOC) for. Objective The purpose was to explore factors to enable successful implementation of the SOC for RA and OA. Methods A combined set of methods was used; a literature search, a European survey among patients, clinicians and policymakers
Previous studies showed that larvae of Methona themisto (Hubner, [ 1818]) (Lepidoptera: Nymphalidae) display a showy yellow color to avoid predation. In addition, these larvae absorb secondary compounds when feeding on Brunfelsia uniflora (Pohl) D. Don (Solanaceae) plants, although this does not prevent pupal parasitism by Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae)
Carry-over effects take place when events occurring in one season influence individual performance in a subsequent season. Blood parasites (e.g. Plasmodium and Haemoproteus) have strong negative effects on the body condition of their hosts and could slow the rate of feather growth on the wintering grounds. In turn, these winter moult costs could reduce reproductive success in the following breedin
The aim of this study was to evaluate how the fixed furniture dimensions match with students' anthropometry and to describe head, upper back and upper limbs postures and movements. Evaluation was performed in 48 students from a Brazilian state school. Furniture dimensions were measured with metric tape, movements and postures by inclinometers (Logger Tecknologi, Akarp, Sweden). Seat height was hig
Multiple levels of earthquake-induced soft-sediment deformations (seismites) are concentrated in the end-Triassic mass extinction interval across Europe. The repetitive nature of the seismites rules out an origin by an extraterrestrial impact. Instead, this intense seismic activity is linked to the formation of the Central Atlantic magmatic province (CAMP). By the earliest Jurassic the seismic act
In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environmental conditions are favourable throughout the year, so that parasites could benefit from a year-round transmission strategy. We analysed how different transm
Purpose The XPC gene is involved in DNA damage recognition in the nucleotide excision repair pathway (NER) We investigated the additive effects of single nucleotide polymorphisms (SNPs) in bladder-cancer patients and population controls for three XPC polymorphisms A499V (C>T) K939Q (A>C) and poly AT (PAT -/+) Experimental Design 311 bladder-cancer patients from a population-based cohort and 337 po
Background: The Toll-like receptor proteins are important in host defense and initiation of the innate and adaptive immune responses. A number of studies have identified associations between genetic variation in the Toll-like receptor genes and allergic disorders such as asthma and allergic rhinitis. The present study aim to search for genetic variation associated with allergic rhinitis in the Tol
