Abstract. Current European waste policy does not mainly aim to treat waste streams but rather place in the foreground of interest the complete supply chain of a product. Waste prevention and re-use do have the highest priority and they take effect before the end-of-life phase of a product or a material is reached. Recycling only takes the third place whereas recovery and disposal represent the…
Core-collapse supernovae are among the most fascinating phenomena in astrophysics and provide a formidable challenge for theoretical investigation. They mark the spectacular end of the lives of massive stars and, in an explosive eruption, release as much energy as the sun produces during its whole life. A better understanding of the astrophysical role of supernovae as birth sites of neutron…
Abstract We establish bounds for the representation dimension of skew group algebras and wreath products. Using this, we obtain bounds for the representation dimension of a block of a Hecke algebra of type A, in terms of the weight of the block. This includes certain blocks of group algebras of symmetric groups.
We show theoretically that the poor can benefit from price changes induced by higher income inequality. As the number of poor increases, the market for products aimed toward the poorgrows, and such products become more profitable. As a result, there are circumstances where an increase in income inequality associates with higher purchasing power of the poor. Using cross-country data on the price…
Background and Aims: Supernumerary B chromosomes (Bs) represent a specific type of selfish genetic element. As Bs are dispensable for normal growth, it is expected to observe B polymorphisms among populations. To address whether Bs maintained in geographically distinct populations of cultivated and weedy rye are polymorphic, the distribution patterns and the transcriptional activity of differe…
Abstract. The gas phase hydrogenation of acrolein over supported silver catalysts has been investigated with a focus on the influence of the support acidity. Acidity has been varied by preparing silver catalysts supported on silica/alumina supports with varying SiO2/Al2O3 ratio.

The reaction network involves hydrogenation of linoleic acid to monoenoic acid isomers, predominantly oleic acid, and further hydrogenation of monoenoic acid…
Abstract Rotary braiding is a cost effective method to manufacture near net shaped preforms that generally have a closed section and may have an arbitrary shape if braiding is performed over a shaped mandrel. The reinforcement architecture can be varied by the number and spacing of active bobbins, and by the speeds used to ‘take-up’ the braid and move the circumferential bobbins. Analytic…
The sky-blue emitting phosphorescent compound Ir(4,6-dFppy)2(acac) (FIracac) doped into different matrices is studied under ambient conditions and at cryogenic temperatures on the basis of broadband and highresolution emission spectra. The emitting triplet state is found to be largely of metal-to-ligand charge transfer (MLCT) character. It is observed that different polycrystalline and amorpho…
An alkoxyphenyl-substituted melamine derivative has been investigated in binary mixtures with twochain and three-chain semiperfluorinated benzoic acids. Equimolar mixtures of the melamine with the complementary benzoic acids form discrete hydrogen-bonded heterodimers with elongated central core. The dimeric supermolecules involving two-chain partially fluorinated acids organize to infinite b…
A novel two-step route for the synthesis of RhFe3N is presented that yields the target material with a significantly improved phase purity. Except from Fe0.5Rh0.5, the absence of other side products is exemplified on the basis of powder XRD, REM/EDX measurements, and Mo¨ssbauer investigations. As predicted from density-functional theory calculations, both Rietveld refinement and Mo¨ssbauer…

Summary 1. Spatiotemporal segregation is often explained by the risk for offspring predation or by differences in physiology, predation risk vulnerability or competitive abilities related to size dimorphism. 2. Most large carnivores are size dimorphic and offspring predation is often intraspecific and related to nonparental infanticide (NPI). NPI can be a foraging strategy, a strategy to re…
he development of a plant leaf is a meticulously orchestrated sequence of events producing a complex organ comprising diverse cell types. The reticulate class of leaf variegation mutants displays contrasting pigmentation between veins and interveinal regions due to specific aberrations in the development of mesophyll cells. Thus, the reticulate mutants offer a potent tool to investigate cell-t…
Heterologous expression of the isoprene synthase gene in the cyanobacterium Synechocystis PCC 6803 conferred upon these microorganisms the property of photosynthetic isoprene (C5H8) hydrocarbons production. Continuous production of isoprene from CO2 and H2O was achieved in the light, occurring via the endogenous methylerythritolphosphate (MEP) pathway, in tandem with the growth of Synechocystis…
Late blight caused by Phytophthora infestans is one of the most devastating diseases of the potato crop. Resistance breeding and current fungicides are unable to control the rapidly evolving P. infestans and new control strategies are urgently needed. This study examined mechanisms of DL-b-aminobutyric acid (BABA)-induced resistance (IR) in the potato–P. infestans system. Leaves from two cult…
