Abstractions, accounts and grid usability

The vision of the Grid is one of seamless, virtual and constantly changing resources where users need not concern themselves about details, such as exactly where an application is running or where their data is being stored. However, seamless and virtual often imply a lack of control that users may be wary of, or even opposed to. Drawing upon our studies of HCI and of collaborative work, this paper examines whether the Grid development community should be taking this vision literally and argues for the need for accountability of systems ‘in interaction’. We give examples of an alternative approach that seeks to provide ways in which administrators, technical support and user communities can make sense of the behaviour of the complex socio-technical ensembles that are the reality of Grids

Production of ethyl acetate from pyrolysis of lignin model compound guaiacylglycerol-β-guaiacyl using TGA-MS

Due to the complex chemical structure of lignin, the fundamental chemistry underlying its pyrolysis behaviour is poorly understood. A detailed knowledge of this chemistry would allow for the construction of detailed predictive chemical kinetic models, which could be used to maximise the efficiency of the pyrolysis process. Lignin is comprised of three monolignols, guaiacyl, p-hydroxyphenyl and syringyl. These are joined together by aryl ether linkages of which β-O-4 is the most common, representing approximately 50% of the linkages found in lignin.[1] In this study, pyrolysis (20oC/minute heating rate) was carried out on a lignin model compound, guaiacylglycerol-β-guaiacyl ether (GGE). GGE is composed of two guaiacyl subunits connected by a β-O-4 linkage, making it broadly representative of the lignin motif and as such an important lignin model compound. A detailed understanding of the thermal degradation of GGE under pyrolysis conditions will provide valuable information of the role of the β-O-4 linkage in lignin.

A Review of Recent Positron Annihilation NDE Applications

This review will treat two recent applications of positron annihilation to metallurgical studies and will involve the measurement of the Doppler effect associated with the gamma rays emitted during positron annihilation. The applications will be: studies of the interactions of dislocations with pre-precipitates in aged Al-4 weight percent Cu single crystals and studies of the effect of hydrogen charging into polycrystalline nickel

Loss of hippocampal serine protease BSP1/neuropsin predisposes to global seizure activity

Serine proteases in the adult CNS contribute both to activity-dependent structural changes accompanying learning and to the regulation of excitotoxic cell death. Brain serine protease 1 (BSP1)/neuropsin is a trypsin-like serine protease exclusively expressed, within the CNS, in the hippocampus and associated limbic structures. To explore the role of this enzyme, we have used gene targeting to disrupt this gene in mice. Mutant mice were viable and overtly normal; they displayed normal hippocampal long-term synaptic potentiation (LTP) and exhibited no deficits in spatial navigation (water maze). Nevertheless, electrophysiological studies revealed that the hippocampus of mice lacking this specifically expressed protease possessed an increased susceptibility for hyperexcitability (polyspiking) in response to repetitive afferent stimulation. Furthermore, seizure activity on kainic acid administration was markedly increased in mutant mice and was accompanied by heightened immediate early gene (c-fos) expression throughout the brain. In view of the regional selectivity of BSP1/neuropsin brain expression, the observed phenotype may selectively reflect limbic function, further implicating the hippocampus and amygdala in controlling cortical activation. Within the hippocampus, our data suggest that BSP1/neuropsin, unlike other serine proteases, has little effect on physiological synaptic remodeling and instead plays a role in limiting neuronal hyperexcitability induced by epileptogenic insult
