Variation in Silene dioica (L.) Clairv.: numerical analysis of populations from Scotland

Numerical analyses (multidimensional scaling and Bk non-hierarchic cluster analysis) of wild populations of Silene dioica (L.) CIairv. from Scotland showed a complex pattern of variation, related partly to habitat and partly to geographic location. Subsets of characters- flower/capsule, seed, and vegetative characters- showed discordance, i.e. imperfectly correlated patterns of variation.Material

SILENE PRATENSIS (RAFN) GODRON & GREN., THE CORRECT NAME FOR WHITE CAMPION OR WHITE COCKLE (SILENE ALBA (MILLER) E. H. L. KRAUSE, NOM. ILLEG.)

Silene alba Muhl. ex Britton (1893), although considered to be an illegitimate substitution for S. nivea (Nutt.) Otth, is validly published and as a result S. alba (Miller) E. H. L. Krause (1901), the widely used name for the weed white campion or white cockle, is illegitimate. It is shown that the correct name for this species in Silene is S. pratensis (Rafn) Godron & Gren. A new taxonomic tr

Wow, this chilli is hot! : Interjections in student grammars of English: a lexical category that is not there.

The paper examines how interjections have been treated in linguistic literature; on what grounds they have been separated from pure response cries; and what their relation is to iconic (onomatopoeic) vocabulary items. Second, the paper examines various English grammars intended for university level students, especially in second language contexts, to see how their treatment of interjections reflec

A NOTE ON THE SEX CHROMOSOMES OF THE VALENCIAN ENDEMIC, SILENE DICLINIS (CARYOPHYLLACEAE)

Abstract:A pair of morphologically differentiated sex chromosomes is reported from the Valencian endemic, Silene diclinis. In S. diclinis, the sex chromosomes differ in centromere position, but X and Y chromosomes are approximately equal in length. In the other dioecious species in Silene sect. Elisanthe, the Y chromosome is considerably longer than the X chromosome.Resumen:Se da noticia de un par

A Double-Injection Control Strategy For Partially Premixed Combustion

Partially Premixed Combustion has shown to be a promising internal combustion concept in terms of engine efficiency and emission levels, however, since the combustion process is partly kinetically controlled, unacceptably high pressure-rise rates could occur at various operating points. A remedy to this problem is the use of a pilot-fuel injection. This paper characterizes double injection effects

Trajectory Generation for Assembly Tasks via Bilateral Teleoperation

For assembly tasks, the knowledge of both trajectory and forces are usually required. Consequently, we may use kinesthetics or teleoperation for recording human demonstrations. In order to have a more natural interaction, the operator has to be provided with a sense of touch. We propose a bilateral teleoperation system which is customized for this purpose. We introduce different coordinate frames

Agency and economic change in regions : identifying routes to new path development using qualitative comparative analysis

This paper investigates the role of human agency in 40 phases of regional economic development in 12 Nordic regions over 30 years. It contributes with a theoretical framework to study agency over time and a fuzzy-set qualitative comparative analysis based on a unique dataset combining over 200 interviews, with printed and online sources, and quantitative data. The paper identifies which combinatio

The Integrated Use of Dendrochronological Data and Paleoecological Records From Northwest European Peatlands and Lakes for Understanding Long-Term Ecological and Climatic Changes—A Review

Our overall understanding of long-term climate dynamics is largely based on proxy data generated from archives such as ice cores, ocean sediments, tree rings, speleothems, and corals, whereas reconstructions of long-term changes in vegetation and associated climate during the Holocene are largely based on paleoecological records from peat and lake sequences, primarily pollen and plant macrofossil

Drought recorded by Ba/Ca in coastal benthic foraminifera

Increasing occurrences of extreme weather events, such as the 2018 drought over northern Europe, are a concerning issue under global climate change. High-resolution archives of natural hydroclimate proxies, such as rapidly accumulating sediments containing biogenic carbonates, offer the potential to investigate the frequency and mechanisms of such events in the past. Droughts alter the barium (Ba)

Supported Lipid Bilayers and the Study of Two-Dimensional Binding Kinetics

Binding between protein molecules on contacting cells is essential in initiating and regulating several key biological processes. In contrast to interactions between molecules in solution, these events are restricted to the two-dimensional (2D) plane of the meeting cell surfaces. However, converting between the more commonly available binding kinetics measured in solution and the so-called 2D bind

Osteomodulin attenuates smooth muscle cell osteogenic transition in vascular calcification

RATIONALE: Vascular calcification is a prominent feature of late-stage diabetes, renal and cardiovascular disease (CVD), and has been linked to adverse events. Recent studies in patients reported that plasma levels of osteomodulin (OMD), a proteoglycan involved in bone mineralisation, associate with diabetes and CVD. We hypothesised that OMD could be implicated in these diseases via vascular calci
