Abstract in German Kurzbiographien zu 104 Lichenologen werden vorgestellt, beginnend mit der alten Zeit von Hoffmann im 18. Jahrhundert mit dem Schwerpunkt der Klassifizierung der Flechten, über das 19. Jahrhundert mit der Entdeckung der Flechtensymbiose durch Schwendener und Stahl, bis in die dynamische Periode des 20. Jahrhunderts mit ihrer enormen wissenschaftlichen Entwicklung. Eine neue GenerShort biographies of 104 lichenologists who have played a key role in the development of German lichenology are provided. These date from Hoffmann and the early days of lichen classification in the 18th century, through the 19th century with the discovery of the lichen symbiosis by Schwendener and Stahl, to the dynamic period of enormous scientific development of the 20th century. A significant bo

Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical homogeneity of the most massive open clusters is needed to better understand the mechanism of their formation and determine the mass limit under which clusters cannot host multiple

Background: Heparin-binding protein is released by neutrophils during inflammation and disrupts the integrity of the alveolar and capillary endothelial barrier implicated in the development of acute lung injury and systemic organ failure. We sought to investigate whether oral administration of simvastatin to patients with acute lung injury reduces plasma heparin-binding protein levels and improves

We study the evolution and renegotiation of the cash-flow rights that venture capitalists (VCs) obtain in their portfolio companies. When company performance between financing rounds is poor, subsequent contracts contain stronger VC cash-flow rights, and existing VCs tend to either give new VCs senior claims or forfeit their existing rights altogether. These results are consistent with the importa

Cerebral amyloid-β aggregation is an early pathological event in Alzheimer disease (AD), starting decades before dementia onset. Estimates of the prevalence of amyloid pathology in persons without dementia are needed to understand the development of AD and to design prevention studies.

This article explores and evaluates three common identifications of the woman in Revelation 12: Mary, mother of Jesus, Israel and the church. This is accomplished through the study of allusions, particularly to the Septuagint, that are embedded in the Greek text. Each verse describing the woman in Revelation 12 has connecting points with one or several texts in the Septuagint and seems to allude t

The ATLAS detector at the Large Hadron Collider is used to search for excited electrons and excited muons in the channel pp -> ll* -> ll gamma, assuming that excited leptons are produced via contact interactions. The analysis is based on 13 fb(-1) of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for excited leptons is found, and a limit is set at the 95% credibility level on the c

Huntington disease (HD) is a fatal neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene. Non-motor symptoms and signs such as psychiatric disturbances, sleep problems and metabolic dysfunction are part of the disease manifestation. These aspects may relate to changes in the hypothalamus, an area of the brain involved in the regulation of emotion, sleep and metabolism.

In this paper we examine whether order imbalances can predict the Chinese stock market returns. We use intraday data, a panel data predictive regression model that accounts for persistent and endogenous order imbalances and cross-sectional dependence in returns, and show that order imbalances predict stock returns from 1-minute trading to 90-minute trading. On the basis of this predictability evid

TRUFFER B. and COENEN L. Environmental innovation and sustainability transitions in regional studies, Regional Studies. Sustainable development and environmental innovations have received increasing attention in regional studies and the related literature. In how far sustainability concerns might also lead to fundamental transformations in technologies, industries and lifestyles (so-called sustain

Vision plays a paramount role in some spider families such as the Salticidae, Lycosidae and Thomisidae, as it is involved in prey hunting, orientation or choice of substrate. In the thomisid Misumena vatia, for which the substrate colour affects the body colour, vision seems to mediate morphological colour changes. However, nothing is known about which component of visual signals from the substrat

The aim of this study was to explore how acid deposition may affect the concentration and quality of dissolved organic matter (DOM) in soil-water. This was done by a small-scale acidification experiment during two years where 0.5 × 0.5 m(2) plots were artificially irrigated with water with different sulfuric acid content, and soil-water was sampled using zero-tension lysimeters under the O-horizon

Abstract in UndeterminedPurpose – The article concerns information literacies in an environment characterised by the two partly competing and contradictory cultures of print and digital. The aim of the paper is to provide a better understanding of the ways in which students assess the credibility of sources they use in school, with a particular interest in how they treat participatory genres.Desig

Most existing differential phase-contrast computed tomography (DPC-CT) approaches are based on three kinds of scanning geometries, described by parallel-beam, fan-beam and cone-beam. Due to the potential of compact imaging systems with magnified spatial resolution, cone-beam DPC-CT has attracted significant interest. In this paper, we report a reconstruction method based on a back-projection filtr

The tracking of small avian migrants has only recently become possible by the use of small light-level geolocators, allowing the reconstruction of whole migration routes, as well as timing and speed of migration and identification of wintering areas. Such information is crucial for evaluating theories about migration strategies and pinpointing critical areas for migrants of potential conservation

CO(2)-laser C-fibre evoked cortical potentials (LCEPs) is a potentially useful animal model for studies of pain mechanisms. A potential confounding factor when assessing analgesic effects of systemically administered drugs using LCEP is sedation. This study aims to clarify: 1) the relation between level of anaesthesia and magnitude of LCEP, 2) the effects of a sedative and an analgesic on LCEP and

Objective: A voluminous umbilical cord has been described in diabetic pregnancies. The aim of this study was to see if measurements of cord diameters might be of value in the evaluation of diabetic pregnancies and especially those suspected of a large for gestational age (LGA) fetus. Methods: In an observational, prospective study umbilical cord areas and vessel diameters were measured between ges
