The Japanese Sect Aum Shrinryko launched their terrorist attack on the Tokyo Underground on the 20 March 1995. Five terrorists boarded underground trains heading for the Kasumigaseki station carrying at least two bags each of liquid Sarin (Isopropyl methylphophonofluoridate ) wrapped in newspaper. These were punctured with the sharpened tip of an umbrella prior to the escape of the perpetrators...

An innovative chromogenic sensing concept based on decomplexation of a tris-(bipyridine)iron(II) coordination complex has been developed for the detection of organophosphorus nerve agents. It was evaluated both on a simulant and real Sarin in vapour and liquid phases.

The connection between the multilevel factorization method re cently proposed by Sarin and Sameh for solving mixed discretizations of the Stokes equation using a divergence free nite element formula tion and hierarchical basis preconditioners is established For the D triangular Taylor Hood element a preconditioning method is proposed that could be useful in fractional step methods

Previous studies on user-product review data have focused on inferring a user’s preferences based on their past reviews and reviews for similar iterms by other users. The objective was to reccommend items that a user might like. Very few studies have considered the chronological order of a user’s reviews. For this project, we evaluate how a user’s choices can be predicted based on thier past re...

To examine the effects of occupational and environmental neurotoxicants on vestibular, cerebellar and spinocerebellar functions, the following three groups of subjects were examined, using a computerized posturography with sway frequency analysis: (1) 49 male chemical factory workers exposed to lead stearate, aged 27-63 (mean 43) years, with concurrent blood lead concentrations (BPbs) of 11-113...

vored media (without quinine). In the critical test phase, demonstrators and observers were exposed separately to the two flavored media. Social transmission occurred if the oviposition choices of observers mirrored that of demonstrators. Using this methodology, Battesti et al. (2012) first showed that observer flies relied heavily on social information and acquired oviposition preferences from...

The most lethal organophosphorus nerve agents (NA), like sarin, soman, agent-VX and Russian-VX, share a methylphosphonate moiety. Pseudomonas diminuta phosphotriesterase (PTE) catalyses the hydrolysis of methylphosphonate NA analogues with a catalytic efficiency orders of magnitude lower than that towards the pesticide paraoxon. With a view to obtaining PTE variants that more readily accept met...

Organophosphate (OP) poisoning is a progressively worrying phenomenon as worldwide pesticide production and consumption has doubled. On average, WHO estimates that 3% of agricultural workers in developing Asian countries suffer an episode of pesticide poisoning every year. Furthermore, the threat of OP usage in terrorism is existent, as seen by the subway tragedy in Tokyo in 1995 where sarin wa...
