1. The responses of single cutaneous mechanoreceptive fibres evoked by a geometrically patterned surface sweeping across the skin were examined. The surfaces used were each a fine diamond-shaped array of "dots' in relief against a flat background. The fibres examined were rapidly adapting, slowly adapting and Pacinian fibres innervating the monkey's finger(More)
Ecosystems are under pressure from multiple human disturbances whose impact may vary depending on environmental context. We experimentally evaluated variation in the separate and combined effects of the loss of a key functional group (canopy algae) and physical disturbance on rocky shore ecosystems at nine locations across Europe. Multivariate community(More)
An epitaxial lift-off technique for removing wide bandgap II–VI heterostructures from GaAs substrates has previously been demonstrated using lattice-matched MgS as the sacrificial layer. However, using MgS as an etch release layer prevents its use as a wide bandgap barrier in the rest of the structure. Here, we describe the use of the etch-resistant alloy(More)
The actions of crude venom from Anemesia species of spider were investigated in cultured dorsal root ganglion neurones from neonatal rats and hippocampal slices. Using mass spectrometry (MALDI-TOF MS), 10-12 distinct peptides with masses between about 3 and 10kDa were identified in the crude spider venom. At a concentration of 5 microg/ml crude Anemesia(More)
