Declines amongst breeding Eider Somateria mollissima numbers in the Baltic/Wadden Sea flyway

We report on the status of the Baltic/Wadden Sea flyway Eider population based on trends in breeding and wintering numbers throughout the region, supplemented by changes in the sex ratio and proportion of young Eiders as monitored in the Danish hunting bag. At the flyway scale, total numbers of breeding pairs decreased by 48% during 2000-2009, after relatively stable breeding numbers in 1991-2000.

Lifshitz transition and Van Hove singularity in a three-dimensional topological Dirac semimetal

A three-dimensional (3D) Dirac semimetal is a novel state of quantum matter which has recently attracted much attention as an apparent 3D version of graphene. In this paper, we report results on the electronic structure of the 3D Dirac semimetal Na3Bi at a surface that reveals its nontrivial ground state. Our studies reveal that the two 3D Dirac cones go through a topological change in the constan

Energy Analysis for Graphics Processors using Novel Methods & Efficient Multi-View Rendering

Real-time rendering is increasingly being performed on battery powered devices, such as laptops and mobile phones. As a result, performance in rendering time is not the only important factor, but the energy consumption is also becoming more and more important, as a lower energy usage directly translates to longer battery time. The main topic of this thesis is energy consumption of graphics process

SO2-catalysed steam pretreatment of quinoa stalks

BACKGROUNDQuinoa is a pseudo-cereal grown predominantly in South America. The quinoa stalks are lignocellulosic residues, which have a limited use today. The objective of the current study was to assess the potential of this material as a source of monosaccharides for fermentation purposes by means of steam pretreatment giving sugars from the hemicellulose part, and enzymatic hydrolysis of the sol

Swedish tonal word accents produced by Vietnamese L1 speakers

This study addresses the question of whether Vietnamese L1 speakers make an adequate distinction in tonal patterns when producing two tonal accent words in their L2, Swedish. Both languages use tonal features to distinguish lexical meaning. Some previous studies suggest that a lexical tonal L1 may provide L2 learners an advantage in perceptually discriminating between different tones in another to

Bayesian methods for meta-analysis of causal relationships estimated using genetic instrumental variables.

Genetic markers can be used as instrumental variables, in an analogous way to randomization in a clinical trial, to estimate the causal relationship between a phenotype and an outcome variable. Our purpose is to extend the existing methods for such Mendelian randomization studies to the context of multiple genetic markers measured in multiple studies, based on the analysis of individual participan

A new nonlocal thermodynamical equilibrium radiative transfer method for cool stars Method and numerical implementation

Context. The solution of the nonlocal thermodynamical equilibrium (non-LTE) radiative transfer equation usually relies on stationary iterative methods, which may falsely converge in some cases. Furthermore, these methods are often unable to handle large-scale systems, such as molecular spectra emerging from, for example, cool stellar atmospheres. Aims. Our objective is to develop a new method, whi

Leadership and the Psychology of Awareness: Three Theoretical Approaches to Information Security Management

The authors argue that Information Security Management (ISM) would benefit from studies that examine the social and psychological mechanisms that, when in evidence, generate employee aware¬ness of information security (IS) related issues. Properly instilled, IS awareness has the power to en¬gender a proactive wariness beyond mechanical guidelines, however detailed. To study how awareness travels i

No title

Our study aims to reveal the most significant aspects of Marin Sorescu’s drama Paracliserul (The Verger) (1970). We point out that the hero’s ambiguous status in the forgotten cathedral is to be considered an iter perfectionis through an incomprehensible maze that life itself is. The existence the verger has to face is empty and shallow. The hero will ultimately find a significance of the world he

Prefermentation improves xylose utilization in simultaneous saccharification and co-fermentation of pretreated spruce.

ABSTRACT: BACKGROUND: Simultaneous saccharification and fermentation (SSF) is a promising process option for ethanol production from lignocellulosic materials. However, both the overall ethanol yield and the final ethanol concentration in the fermentation broth must be high. Hence, almost complete conversion of both hexoses and pentoses must be achieved in SSF at a high solid content. A principal

Suicidal Intent and the HPA-Axis Characteristics of Suicide Attempters with Major Depressive Disorder and Adjustment Disorders.

The main purpose of the study was to investigate Hypothalamic-Pituitary-Adrenal (HPA) axis characteristics in relation to suicidal intent among suicide attempters with Major Depressive Disorder (MDD) and Adjustment Disorders (AD). The relationship between suicidal intent, assessed by means of the Suicidal Intent Scale (SIS), and serum cortisol after a Dexamethasone Suppression Test (DST) was inves

The Laptev Sea walrus Odobenus rosmarus laptevi: an enigma revisited

The walrus (Odobenus rosmarus) is in some current systematic schemes divided into three subspecies: O. r. rosmarus in the North Atlantic, O. r. divergens in the North Pacific and O. r. laptevi in the Laptev Sea. These three subspecies have been described as differing in body size, but the taxonomic status of O. r. laptevi is disputed. The current study applies molecular and morphometric methods to

High-temperature thermal stability of nanocrystalline Cr2O3 films deposited on silicon wafers by arc ion plating

In this work, the high-temperature thermal stability of nanocrystalline Cr2O3 films on Si wafers deposited at various bias voltages was systematically investigated by means of a symmetrical high-resolution thermogravimetric system. In the meantime, the effects of substrate bias voltage on the morphology, microstructure, crack area percentage, phase constituents, and grain size of the heat-treated

Colloidal lithography for fabricating patterned polymer-brush microstructures

We exploit a series of robust, but simple and convenient colloidal lithography (CL) approaches, using a microsphere array as a mask or as a guiding template, and combine this with surface-initiated atom-transfer radical polymerization (SI-ATRP) to fabricate patterned polymer-brush microstructures. The advantages of the CL technique over other lithographic approaches for the fabrication of patterne

Meta-analysis of genome-wide association data and large-scale replication identifies additional susceptibility loci for type 2 diabetes

Genome-wide association (GWA) studies have identified multiple loci at which common variants modestly but reproducibly influence risk of type 2 diabetes (T2D)(1-11). Established associations to common and rare variants explain only a small proportion of the heritability of T2D. As previously published analyses had limited power to identify variants with modest effects, we carried out meta-analysis
