Systematics and conservation genetics of Dactylorhiza majalis ssp elatior (Orchidaceae) on Gotland

A tall allotetraploid member of the Dactylorhiza incarnata/maculata complex with unspotted leaves and large pinkish flowers from the island of Gotland in the Baltic was examined for molecular variation patterns at five nuclear microsatellite loci, nuclear ITS and in plastid haplotypes. The allotetraploid was well separated from allopatric allotetraploids of similar appearance, including the wester

Evaluating the Effect of Biofilm Thickness on Nitrification in Moving Bed Biofilm Reactors.

This study evaluates the effect of biofilm thickness on the nitrifying activity in moving bed biofilm reactors (MBBRs) in a controlled environment. In-depth understanding of biofilm properties in MBBRs and their effect on the overall treatment efficiency compose the key to optimizing process stability and efficiency. However, evaluating biofilm properties in continuously operated MBBRs can be extr

A method for rapid screening of ketone biotransformations: Detection of whole cell Baeyer-Villiger monooxygenase activity.

A method for screening of ketone biotransformations was developed and applied to the identification of Baeyer-Villiger monooxygenase (BVMO) activity. The method was based on the formation of a purple coloured product on reaction between an enolizable ketone and 3,5-dinitrobenzoic acid in an alkaline solution. Absorbance of the colour decreased with the size of the cycloketone ring. Stoichiometric

Functional integration of new hippocampal neurons following insults to the adult brain is determined by characteristics of pathological environment.

We have previously shown that following severe brain insults, chronic inflammation induced by lipopolysaccharide (LPS) injection, and status epilepticus, new dentate granule cells exhibit changes of excitatory and inhibitory synaptic drive indicating that they may mitigate the abnormal brain function. Major inflammatory changes in the environment encountering the new neurons were a common feature

Bystander behavior in bullying situations: Empathy, moral disengagement and defender self-efficacy

The aim of the present study was to investigate how basic moral sensitivity in bullying, moral disengagement in bullying and defender self-efficacy were related to different bystander behaviors in bullying. Therefore, we examined pathways that linked students’ basic moral sensitivity, moral disengagement, and defender self-efficacy to different bystander behaviors in bullying situations. Three hun

Defect Free PbTe Nanowires Grown by Molecular Beam Epitaxy on GaAs(111)B Substrates

The molecular beam epitaxial growth of PbTe nanowires oil GaAs(111)B substrates is reported. The growth process was based oil the Au-catalyzed vapor-liquid-solid mechanism. These nanowires grow along the [100] axis; they are perpendicular to the substrate, have tapered shapes, and have diameters of about 90 rim at the base and 60 run at the top. High resolution transmission electron microscopy pic

Cross-species utility of 22 microsatellite markers in the Melodious Warbler (Hippolais polyglotta)

Microsatellites are a valuable tool in the analysis of population genetic structure. Utilising microsatellite markers that were originally isolated from other species (cross-species amplification) can prove an efficient way, in terms of time and cost, to obtain markers for genetic studies. Here, 55 avian microsatellite primer pairs were tested for the cross-amplification in the Melodious Warbler (

Orthogonal multiplet bases in SU(N-c) color space

We develop a general recipe for constructing orthogonal bases for the calculation of color structures appearing in QCD for any number of partons and arbitrary N-c. The bases are constructed using hermitian gluon projectors onto irreducible subspaces invariant under SU(N-c). Thus, each basis vector is associated with an irreducible representation of SU(N-c). The resulting multiplet bases are not on

Environmental Hexachlorobenzene exposure and human male reproductive function.

Hexachlorobenzene (HCB) is a persistent environmental fungicide that may disrupt androgen regulation. The aim of this study was to investigate associations between HCB levels and biomarkers of male reproductive function. 589 spouses of pregnant women from Greenland, Poland and Ukraine were enrolled between 2002 and 2004. The men provided semen and blood samples and were interviewed. HCB was measur

"m=1" coatings for neutron guides

A substantial fraction of the price for a supermirror neutron guide system is the shielding, which is needed because of the gamma radiation produced as a result of neutron absorption in the supermirror layers. Traditional coatings have been made of nickel-titanium heterostructures, but Ni and Ti also have a fairly high absorption cross section for cold and thermal neutrons. We examine a number of

How to extract physics from nu (dyn)

In this paper we summarize the properties of nu (dyn) and discuss briefly how the results can be interpreted in terms of a simple pair-production model. The ideas are then illustrated in detail with a PYTHIA simulation study of forward-backward correlations in pp collisions.

miR-187 Is an Independent Prognostic Factor in Breast Cancer and Confers Increased Invasive Potential In Vitro

Purpose: Here, we describe an integrated bioinformatics, functional analysis, and translational pathology approach to identify novel miRNAs involved in breast cancer progression. Experimental Design: Coinertia analysis (CIA) was used to combine a database of predicted miRNA target sites and gene expression data. Using two independent breast cancer cohorts, CIA was combined with correspondence anal

Political Mythmaking and the 2014 Winter Olympics in Sochi: Olympism and the Russian Great Power Myth

The theoretical point of departure of this paper is that the perspective of political myth adds to the understanding of political developments in Russia. The upcoming Olympic Winter Games in Sochi in 2014 are discursively constructed as a manifestation of Russia's return to great power status. In official Russian discourse, there is an encounter between the Russian great power myth and the myth of

Measurement of the production cross section of jets in association with a Z boson in pp collisions at root s=7 TeV with the ATLAS detector

Measurements of the production of jets of particles in association with a Z boson in pp collisions at root s = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transv

Cerebrospinal Fluid Microglial Markers in Alzheimer's Disease: Elevated Chitotriosidase Activity but Lack of Diagnostic Utility

Activated microglial cells, which are the resident macrophages of the central nervous system, surround amyloid beta-plaques in Alzheimer's disease (AD) brains. Inflammation including microglial activation may contribute in AD pathogenesis, and biomarkers for this process may thus be of value to study AD pathogenesis and might facilitate development of therapies targeting these cells. We therefore

Hormonal exposures and the risk of uveal melanoma

Several studies suggest that hormonal mechanisms may be associated with the development of uveal melanoma. Therefore, the association between the risk of uveal melanoma and exposure to hormonal exposures was investigated in a case-control study from nine European countries. Incident cases of uveal melanoma were frequency-matched to population and hospital controls by country, age, and sex. Female
