A multigene phylogenetic synthesis for the class Lecanoromycetes (Ascomycota): 1307 fungi representing 1139 infrageneric taxa, 317 genera and 66 families.

The Lecanoromycetes is the largest class of lichenized Fungi, and one of the most species-rich classes in the kingdom. Here we provide a multigene phylogenetic synthesis (using three ribosomal RNA-coding and two protein-coding genes) of the Lecanoromycetes based on 635 newly generated and 3307 publicly available sequences representing 1139 taxa, 317 genera, 66 families, 17 orders and five subclass

Increased Risk of Arthropathies and Joint Replacement Surgery in Patients With Genetic Hemochromatosis: A Study of 3,531 Patients and Their 11,794 First-Degree Relatives

Objective Genetic hemochromatosis (GH) is an autosomal recessive disease in individuals of Northern and Western European descent. Heterozygosity for the C282Y mutation is common (620%). Arthropathy is one of the few complications of GH suggested not to be associated with iron body stores; synovial iron deposition remains in iron-depleted patients. Previous studies suggest an elevated prevalence of

The Rise of Social Product Development

The aim of the paper is to discuss the rising potential of social software to increase the knowledge management capabilities of virtual product development teams. It presents six fundamental transitions, elaborated from the empirical findings, which justify the rise of a more bottom-up, social creation and sharing of engineering knowledge in the virtual organisation. The study suggests that tradit

Familial and neighborhood effects on psychiatric disorders in childhood and adolescence

Background: More knowledge is needed on potential associations between individual-, family-, and neighborhood-level factors and psychiatric disorders in children and adolescents. Aims: To examine associations between, individual-, family-, and neighborhood-level factors and incident internalizing (anxiety and mood) disorders and externalizing (ADHD and conduct) disorders in children and adolesc

Effects of Immersion Solvent on Photovoltaic and Photophysical Properties of Porphyrin-Sensitized Solar Cells.

Memory effects in self-assembled monolayers (SAMs) of zinc porphyrin carboxylic acid on TiO2 electrodes have been demonstrated for the first time by evaluating the photovoltaic and electron transfer properties of porphyrin-sensitized solar cells prepared by using different immersion solvents sequentially. The structure of the SAM of the porphyrin on the TiO2 was maintained even after treating the

Alternating Projections on Nontangential Manifolds

We consider sequences of points obtained by projecting a given point B=B (0) back and forth between two manifolds and , and give conditions guaranteeing that the sequence converges to a limit . Our motivation is the study of algorithms based on finding the limit of such sequences, which have proved useful in a number of areas. The intersection is typically a set with desirable properties but for w

Cosmopolitan practices in social contexts: Swedish skilled migrants in the Netherlands

Empirical work on cosmopolitanism has, to a large extent, focused on the precon- ditions for and character of cosmopolitan practices. Drawing on interviews with Swedish skilled migrants in the Netherlands, this article contributes to the cosmo- politan research by focusing on the socially structured variety of cosmopolitan practices. Based on an understanding of cosmopolitanism as an active and re

Efficient Message Passing Scheduling for Terminated LDPC Convolutional Codes

Message passing schedules that reduce the decoding complexity of terminated LDPC convolutional code ensembles are analyzed. Considering the AWGN channel, various schedules are compared by means of density evolution. The results of the analysis together with computer simulations for some (3,6)-regular codes confirm that sliding window decoding is an attractive practical solution for low-latency and

Estimations of isoprenoid emission capacity from enclosure studies: measurements, data processing, quality and standardized measurement protocols

The capacity for volatile isoprenoid production under standardized environmental conditions at a certain time (E-S, the emission factor) is a key characteristic in constructing isoprenoid emission inventories. However, there is large variation in published E-S estimates for any given species partly driven by dynamic modifications in E-S due to acclimation and stress responses. Here we review addit

Children having magnetic resonance imaging: A preparatory storybook and audio/visual media are preferable to anesthesia or deep sedation.

As a magnetic resonance imaging (MRI) examination lasts about 45 minutes and as the technique is sensitive to motion, children are often given sedation or anesthesia. The aim of this study was to examine whether children aged three to nine years could undergo MRI while awake and achieve adequate image quality if age-adjusted routines were used. A two-group controlled experimental design was used.

Charged-pion cross sections and double-helicity asymmetries in polarized p plus p collisions at root s=200 GeV

We present midrapidity charged-pion invariant cross sections, the ratio of the pi(-) to pi(+) cross sections and the charge-separated double-spin asymmetries in polarized p + p collisions at root s = p + 200 GeV. While the cross section measurements are consistent within the errors of next-to-leading-order (NLO) perturbative quantum chromodynamics predictions (pQCD), the same calculations overesti

Free radical production and ischemic brain damage: influence of postischemic oxygen tension

It is now becoming increasingly clear that free radicals contribute to brain damage in several conditions, such as hyperoxia and trauma. It has been more difficult to prove that free radical production mediates ischemic brain damage, but it has often been suggested that it may be a major contributor to reperfusion damage, observed following transient ischemia. Recent results demonstrate that cereb

Pseudo-rotation mechanism for fast olefin exchange and substitution processes at orthometalated C,N-complexes of platinum(II)

Bridge splitting in chloroform of the orthometalated chloro-bridged complex [Pt(mu-Cl)(2-Me2NCH2C6H4)](2) (1), with ethene, cyclooctene, allyl alcohol and phosphine according to 1 + 2L --> 2 [PtCl(2-Me2NCH2C6H4)(L)], where L = C2H4 (3a), C8H14, (3b), CH2CHCH2OH (3c), and PPh3 (4a and 4b) gives monomeric species with L coordinated trans or cis to aryl. With olefins the thermodynamically stable isom

Intimate partner violence against women, health effects and health care seeking in rural Vietnam

Background: Health effects and health care seeking were investigated among women in rural Vietnam exposed to physical and/or sexual violence from their partner in the past year. The study was conducted within the framework of the demographic surveillance site in Bavi District, Ha Tay Province in northern Vietnam. Methods: Face-to-face interviews based on a questionnaire developed by the WHO for us

Stressful experiences in relation to depth of sedation in mechanically ventilated patients.

n mechanically ventilated patients, sedatives and analgesics are commonly used to ensure comfort, but there is no documented knowledge about the impact of depth of sedation on patients' perception of discomfort. The aim of this study was, therefore, to investigate the relationship between stressful experiences and intensive care sedation, including the depth of sedation. During 18 months, 313 intu

Periplasmic c Cytochromes and Chlorate Reduction in Ideonella dechloratans

The aim of this study was to clarify the pathway of electron transfer between the inner membrane components and the periplasmic chlorate reductase. Several soluble c-type cytochromes were found in the periplasm. The optical difference spectrum of dithionite-reduced periplasmic extract shows that at least one of these components is capable of acting as an electron donor to the enzyme chlorate reduc

The theoretical basis of a method to determine the fracture energy GF of concrete

RILEM Technical Committee 50 - Fracture Mechanics of Concrete, has put forward a proposal for a recommendation for the determination of the fracture energy G//F of mortar and concrete. The significance of G//F in the strength of concrete structures is discussed and it is demonstrated that G//F in some cases, for example for shear failure of beams and slabs without shear reinforcement, is a materia
