Between X-ray tubes and large-scale synchrotron sources, a large gap in performance exists with respect to the monochromaticity and brilliance of the X-ray beam. However, due to their size and cost, large-scale synchrotrons are not available for more routine applications in small and medium-sized academic or industrial laboratories. This gap could be closed by laser-driven compact synchrotron ligh
We have prepared a model catalytic system by depositing Pd onto a TiO2(110) surface held at similar to 720 K. Scanning tunneling microscopy (STM) reveals well-defined Pd nanocrystals consisting of (111) top facets with {111} and {100} side facets. The Pd nanocrystals go down to about 10 nm in width and 1.3 nm in height. Top facets can be imaged with atomic resolution, indicating the absence of TiO
Purpose: To evaluate how children with spina bifida (SB) participate in school-related activities and to explore if their motor and process skills in task performance were related to their level of active participation in school. Method: Fifty children from a geographical cohort of children with SB (aged 6-14 years) and their teachers rated the children's frequency of participation in school-relat
A novel method for two-dimensional fluorescence lifetime imaging is presented. The technique is demonstrated on averaged planar laser-induced fluorescence (PLIF) signals recorded in a flame. Although demonstrated on averaged images, the concept applies equally well to single-shot images. Formaldehyde was probed through pico-second excitation at 355 nm in a rich methane/oxygen flame (Phi = 2.6). Im
This paper aims to develop a framework for an integrated empirical and normative policy analysis practicable for evaluating environmental and forest sub-policies regarding their contribution to democratic policy-making. For this reason Habermas meta-model on deliberative democracy is translated to the policy level by merging it with the Policy Arrangement Approach (PAA) of Arts and Van Tatenhove.
Chronic hyperglycemia leads to pancreatic beta-cell dysfunction characterized by diminished glucose-stimulated insulin secretion (GSIS), but the precise cellular processes involved are largely unknown. Here we show that pancreatic beta-cells chronically exposed to a high glucose level displayed substantially increased amounts of stress fibers compared with beta-cells cultured at a low glucose leve
The internal dosimetry computer program internal dose assessment by computer (IDAC) for calculations of absorbed doses to organs and tissues as well as effective doses to patients from examinations with radiopharmaceuticals has been developed. The new version, IDAC2.0, incorporates the International Commission on Radiation Protection (ICRP)/ICRU computational adult male and female voxel phantoms a
Individuals with diabetes mellitus are advised to achieve a healthy weight to prevent complications. However, fat mass distribution has hardly been investigated as a risk factor for diabetes complications. The authors studied associations between body mass index, waist circumference, waist/hip ratio, and waist/height ratio and mortality among individuals with diabetes mellitus. Within the European
Semiconducting carbon nanotubes (CNTs) have several properties that are advantageous for field effect transistors such as high mobility, good electrostatics due to their small diameter allowing for aggressive gate length scaling and capability to withstand high current densities. However, in spite of the exceptional performance of single transistors only a few simple circuits and logic gates using
This is a review of Brett M. Frischmann's "Infrastructure : the social value of shared resources" (2012). It is a rich book that neither ducks from challenging the disciplinary boundaries of economic theory nor from complex issues of spillover effects or hard-to-measure externalitites. Frischmann’s contribution includes the grand task of comparing and analysing the very much different types of inf
Advances in laboratory techniques have led to a rapidly increasing use of biomarkers in epidemiological studies. Biomarkers of internal dose, early biological change, susceptibility and clinical outcomes are used as proxies for investigating the interactions between external and/or endogenous agent.; and the body components or processes. The need for improved reporting of scientific research led t
High levels of insulin-like growth factor-1 (IGF-1) have been associated with increased risk of developing several types of cancer including breast cancer. A set of nine haplotype tagging SNPs (htSNPs) in the IGF1 gene were associated with IGF-1 levels and prostate cancer in a Swedish population. We aimed to study the nine htSNPs in three haplotype blocks (block1: rs855211, rs35765, rs2162679; blo
Optogenetics is an emerging powerful tool to investigate workings of the nervous system. However, the use of low tissue penetrating visible light limits its therapeutic potential. Employing deep penetrating near-infrared (NIR) light for optogenetics would be beneficial but it cannot be used directly. This issue can be tackled with upconversion nanoparticles (UCNs) acting as nanotransducers emittin
We performed fine mapping of 39 established type 2 diabetes (T2D) loci in 27,206 cases and 57,574 controls of European ancestry. We identified 49 distinct association signals at these loci, including five mapping in or near KCNQ1. 'Credible sets' of the variants most likely to drive each distinct signal mapped predominantly to noncoding sequence, implying that association with T2D is mediated thro
Sore throat is common in primary healthcare. Aetiological studies have focused on the presence of a limited number of pathogens. The aim of the present study was to investigate the presence of a wide range of bacteria and viruses, including Fusobacterium necrophorum, in patients with pharyngotonsillitis and in asymptomatic controls. A prospective case control study was performed in primary healthc
In this study, one-to-one tuition in higher music education (HME) was theorised as a culturally and historically grounded activity system consisting of relation- ships between musicians, instruments, music-making traditions and audiences. The ‘skills paradox’, as seen in the inherent conflict between musicians’ need for long-term artistic training and society’s demands for flexible knowledge produ
Human embryonic stem cells (hESCs) are a promising source for cell replacement therapies. Parkinson's disease is one of the candidate diseases for the cell replacement therapy since the motor manifestations of the disease are associated with the loss of dopaminergic neurons in the substantia nigra pars compacta. Stromal cell-derived inducing activity (SDIA) is the most commonly used method for the
