Poison sedge can kill stock
POISON SEDGE was first suspected of being toxic to livestock in Western Australia nearly 80 years ago.
Sudden deaths of sheep grazing areas on which poison sedge grew have been reported from many regions from Geraldton to Scott River.
This article reports a case of poisoning in the field, and the experimental reproduction of poison sedge toxicity in pen-fed sheep

Cytoplasmic localization of calcium/calmodulin-dependent protein kinase I-α depends on a nuclear export signal in its regulatory domain
AbstractCalcium/calmodulin-dependent protein kinase I-α (CaMKI-α) is a ubiquitous cytosolic enzyme that phosphorylates a number of nuclear proteins in vitro and has been implicated in transcriptional regulation. We report that cytoplasmic localization of CaMKI-α depends on CRM1-mediated nuclear export mediated through a Rev-like nuclear export signal in the CaMKI-α regulatory domain. Interaction of CaMKI-α with a CRM1 complex in vitro is enhanced by incubation with calcium/calmodulin. Translocation of CaMKI-α into the nucleus involves a conserved sequence located within the catalytic core. Mutation of this sequence partially blocks nuclear entry of an export-impaired mutant of CaMKI-α
Investigation of fiber/matrix adhesion: test speed and specimen shape effects in the cylinder test
The cylinder test, developed from the microdroplet test, was adapted to assess the interfacial adhesion strength between fiber and matrix. The sensitivity of cylinder test to pull-out speed and specimen geometry was measured. It was established that the effect of test speed can be described as a superposition of two opposite, simultaneous effects which have been modeled mathematically by fitting two parameter Weibull curves on the measured datas. Effects of the cylinder size and its geometrical relation on the measured strength values have been analyzed by finite element method. It was concluded that the geometry has a direct influence on the stress formation. Based on the results achieved, recommendations were given on how to perform the novel single fiber cylinder test
'Mindless markers of the nation': The routine flagging of nationhood across the visual environment
The visual environment has increasingly been used as a lens with which to understand wider processes of social and economic change with studies employing in-depth qualitative approaches to focus on, for example, gentrification or trans-national networks. This exploratory paper offers an alternative perspective by using a novel method, quantitative photo mapping, to examine the extent to which a particular socio-cultural marker, the nation, is ‘flagged’ across three contrasting sites in Britain. As a multi-national state with an increasingly diverse population, Britain offers a particularly fruitful case study, drawing in debates around devolution, European integration and Commonwealth migration. In contributing to wider debates around banal nationalism, the paper notes the extent to which nations are increasingly articulated through commerce, consumption and market exchange and the overall significance of everyday markers (signs, objects, infrastructure) in naturalising a national view of the world
