Exotic nuclei are produced via projectile fragmentation of different primary beams in beryllium targets placed at the entrance of the Fragment Separator (FRS). The fragments are spatially separated by the FRS, injected and stored in the Experimental Storage Ring (ESR) for direct mass measurements. Two complementary methods have been applied: 1 Schottky Mass(More)
Recent progress is presented from experiments on masses and lifetimes of bare and few-electron exotic nuclei at GSI. Relativistic rare isotopes produced via projectile fragmentation and fission were separated in flight by the fragment separator FRS and injected into the storage ring ESR. This worldwide unique experimental technique gives access to all(More)
The FRS-ESR facility at GSI provides unique conditions for precision measurements of large areas on the nuclear mass surface in a single experiment. Values for masses of 604 neutron-deficient nuclides (30 < or = Z < or = 92) were obtained with a typical uncertainty of 30 microu. The masses of 114 nuclides were determined for the first time. The odd-even(More)
Tele-centres offer a low cost opportunity for the many who cannot afford their own phone or Internet connection. This paper presents a field study of tele-centres in Ghana and analyses how they contribute to universal access.

Introduction The use of technology is an important factor in the organisation of our society. When we speak of a model for the future society we often use the term the information society or the networked society. Information society and network society are not new concepts but have existed for many years (Machlup, 1962 and Nora & Minc, 1980). The reason(More)
