The gas composition surrounding a catalytic sample has direct impact on its surface structure, which is essential when in situ investigations of model catalysts are performed. Herein a study of the gas phase close to a Pd(110) surface during CO oxidation under semirealistic conditions is presented. Images of the gas phase, provided by planar laser-induced fluorescence, clearly visualize the format

The Summary In 27 centres across Europe, the prevalence of deforming spinal Scheuermann's disease in age-stratified population-based samples of over 10,000 men and women aged 50+ averaged 8 % in each sex, but was highly variable between centres. Low DXA BMD was un-associated with Scheuermann's, helping the differential diagnosis from osteoporosis. Introduction This study aims to assess the prevale

Background: A physically active life promotes both physical and mental health, increasing well-being and quality of life. Physical activity (PA) performed outdoors has been found to be particularly good for promoting well-being. However, participation in PA can change during the course of a lifetime. Parenthood has been found to be a life event associated with decreased PA, especially among women,

Public procurement for innovation is a matter of using public demand to trigger innovation. Empirical studies have demonstrated that demand-based policy instruments can be considered to be a powerful tool in stimulating innovative processes among existing firms. However, the existing literature has not focused on the role this policy instrument can play in the promotion of (knowledge-intensive) en

The dynamic behavior of surface accommodated chlorine atoms on RuO2(110) was studied by a variety of experimental methods including high resolution core level shift, thermal desorption-, and in situ infrared spectroscopy as well as in situ surface X-ray diffraction in combination with state-of-the-art density functional theory calculations. On the chlorinated RuO2(110) surface the undercoordinated

This article compares and assesses four freely available cross-sectional time-series data sets in terms of their information on ballot structure, district structure, and formula of the electoral system in use for lower house and, if relevant, upper house and presidential elections. The authors find that the choice of data source matters for conclusions drawn on the consequences of electoral system

BACKGROUND: Understanding the dispersal and genetic structure of invasive insects across islands is important for designing management plans that are appropriate at spatial and temporal scales. For invasive parasites, population dynamics are largely determined by the distribution and density of their host species. The introduced parasitic fly, Philornis downsi, parasitises nestlings of endemic bir

Fetal cardiotocography is characterized by low specificity; therefore, in an attempt to ensure fetal well-being, fetal scalp blood sampling has been recommended by most obstetric societies in the case of a non-reassuring cardiotocography. The scientific agreement on the evidence for using fetal scalp blood sampling to decrease the rate of operative delivery for fetal distress is ambiguous. Based o

The adaptive immune system is responsible for final clearance and long lasting immunological memory of invading pathogens. ...

Premise of the study: Numerous long-term studies in seasonal habitats have tracked interannual variation in first flowering date (FFD) in relation to climate, documenting the effect of warming on the FFD of many species. Despite these efforts, long-term phenological observations are still lacking for many species. If we could forecast responses based on taxonomic affinity, however, then we could l

The Tile hadronic calorimeter of the ATLAS detector has undergone extensive testing in the experimental hall since its installation in late 2005. The readout, control and calibration systems have been fully operational since 2007 and the detector has successfully collected data from the LHC single beams in 2008 and first collisions in 2009. This paper gives an overview of the Tile Calorimeter perf

Cyanobacteria-plant symbioses play an important role in many ecosystems due to the fixation of atmospheric nitrogen (N) by the cyanobacterial symbiont. The ubiquitous feather moss Pleurozium schreberi (Brid.) Mitt. is colonized by cyanobacteria in boreal systems with low N deposition. Here, cyanobacteria fix substantial amounts of N-2 and represent a potential N source. The feather moss appears to

The aim of the study was to determine the usefulness of diffusion tensor tractography (DTT) in parkinsonian disorders using a recently developed method for normalization of diffusion data and tract size along white matter tracts. Furthermore, the use of DTT in selected white matter tracts for differential diagnosis was assessed.

This article discusses ethics and equality using the philosophy of Emmanuel Levinas within the field of educational relations. Levinas usually focuses on ethics, but in this article I also discuss his parallel political dimension which makes equality possible. Levinas’ argument of infinite asymmetrical positions is used in an expanded sense to also include infinite individuals. This leads to a vie

Lipoproteins in blood play an important physiological role transporting cholesterol, lipids and lipid-soluble substances to the different organs of the body. Diseases such as atherosclerosis, cardiovascular disease and stroke are associated with defects in lipoprotein metabolism. For many years, intense research has focused on the role of cholesterol in development of atherosclerosis. Cholesterol

The general aim of the thesis was to contribute to a more evidenced based framework in the surgical treatment of diseases in the gastroesophageal junction (GEJ), by comparing outcome, measured by complication and survival rates, and evaluate different reconstructions regarding long-term symptoms and quality of life (QoL). The GEJ is a poorly defined anatomic area that represents the lower part of
