Gender has long been recognised as important within environmental issues, but there has been considerable debate over how to conceptualise the gender ^ environment nexus. As feminist theorising around women and gender has changed, so have conceptualisations about gender and environment, leading to a key debate within ecofeminism and related literatures about whether there is an essential or a c...

We calculate the CP–violating effects in the top quark semi–leptonic three body decays induced by the supersymmetric CP–odd phase of the top squark trilinear soft breaking term arg(At). The light top squark mass is assumed to be close to the top quark mass mt̃ ∼ mt. The CP–conserving phase is provided by the χ+ and χ0 cut. We find that the partial rate asymmetry is in the 0.1% level. In the most...

Top quarks are produced in pairs via the strong interaction. At the Tevatron, operating at 1.96 TeV in Run II, the expected production rate of tt pairs is 6.8±0.6 pb @ mt=175 GeV/c . Roughly 85% arise from qq interactions, while the remaining 15% are created by gluon fusion. As of February 4, 2007, 2.05 fb of data have been recorded by the D0 experiment. To study the properties of the top quark...

Educating people with special educational needs (SEN) is a hot topic these days. Many multimedia educational tools have been generated with the support of ICT to assist children receiving SEN education. Teaching supported by new technologies should guarantee contents accessibility. However, these tools are not 100% suitable because the adaptation process they implement does not take into accoun...
