Case studies in web sustainability

At the moment organisations often make significant investments in producing Web-based material, often funded through public money, for example from JISC. But what happens when some of those organisations are closed or there is no longer any money or resources to host the site? We are seeing cuts in funding or changes in governmental policy, which is resulting in the closure of some of these organisations. What happens to those Web resources when the organisations are no longer in existence? Public money has often been used to develop these resources - from that perspective it would be a shame to lose them. Moreover, the resources might be needed or someone may actually want to take over the maintenance of the site at a later date. How do we make these sites more sustainable? Is there any way we can move sites to somewhere that is free to host the Web pages, and can be left there or modified when needed? JISC previously funded three projects to look at this area through a programme called Sustaining ‘at risk’ online resources [1]. One of these projects, which ran at The University of Northampton, looked into ‘rescuing’ one of the recently closed East Midlands Universities Association’s online resources. This resource, called East Midlands Knowledge Network (EMKN), lists many of the knowledge transfer activities of 10 of the East Midlands universities. The project looked at options on how to migrate the site to a free hosting option to make it make it more sustainable even when it is no longer available on the original host’s servers. This article looks at this work as a case study on Web sustainability and also included a case study of another project where Web sustainability was centra

Junkbots

The School of Science and Technology at the University of Northampton have been working with local schools to create robots made from junk and also to use robots programmed by the students to perform simple rubbish clearing exercises. This is an initiative by the University to introduce environmental sustainability, engineering and computing to students in school

O-ring gasket test fixture

An apparatus is presented for testing O-ring gaskets under a variety of temperature, pressure, and dynamic loading conditions. Specifically, this apparatus has the ability to simulate a dynamic loading condition where the sealing surface in contact with the O-ring moves both away from and axially along the face of the O-ring

Is a Massive Tau Neutrino Just What Cold Dark Matter Needs?

The cold dark matter (CDM) scenario for structure formation in the Universe is very attractive and has many successes; however, when its spectrum of density perturbations is normalized to the COBE anisotropy measurement the level of inhomogeneity predicted on small scales is too large. This can be remedied by a tau neutrino of mass 1\MeV - 10\MeV and lifetime $0.1\sec - 100\sec$ whose decay products include electron neutrinos because it allows the total energy density in relativistic particles to be doubled without interfering with nucleosynthesis. The anisotropies predicted on the degree scale for ``$\tau$CDM'' are larger than standard CDM. Experiments at $e^\pm$ colliders may be able to probe such a mass range.Comment: 9 pages LaTeX plus 4 figures (available upon request) FERMILAB--Pub--94/026-
