The authors present a higher-order Godunov method for the solution of the twoand three-dimensional equations of ideal magnetohydrodynamics (MHD). This work is based both on a suitable operator-split approximation to the full multidimensional equations, and on a one-dimensional Riemann solver. TIlls Riemann solver is sufficiently robust to handle the nonstrictly hyperbolic nature of the MHD equa...

I review recent constraints on and claimed detections of a time-varying fine-structure constant α. Our results are consistent with no variation in α from the epoch of recombination to the present day, and restrict any such variation to be less than about 4%. The forthcoming MAP and Planck experiments will be able to break most of the currently existing degeneracies between α and other cosmologi...

the acehnese mahseer, locally known as keureling, tor tambra is one of the highest economically valued freshwater fishes found in aceh waters. the culture of t. tambra was initiated in aceh province, indonesia more than five years ago. however, the growth rate in captivity has been low, probably due to feeding problems. hence, the objective of the present study was to evaluate the optimum level...

s100ß a neurotrophic factor mainly released by astrocytes, has been implicated in the pathogenesis of bipolar disorder. thus, lithium may exert its neuroprotective effects to some extent through s100ß. furthermore, the possible effects of lithium on astrocytes as well as on interactions between neurons and astrocytes as a part of its mechanisms of actions are unknown. this study was undertaken...

Three groups of 11 New Zealand White (NZW) rabbit does, each were reared from 12 weeks of age on iso-energetic diets containing 16, 14 or 12% crude protein (CP) were used to study influences on productive performance, digestibility, some carcass traits, haematological, biochemical and hormonal parameters of rabbit does. The results showed rabbits fed on 16% protein diet had heavier body weights...

We compute the boundary entropies for the allowed boundary conditions of the SU (2)-invariant principal chiral model at level k = 1. We used the reflection factors determined in ref.[27]. As a by-product we obtain some miscellaneous results such as the ground-state energy for mixed boundary conditions as well as the degeneracies of the Kondo model in the underscreened and exactly screened cases...

Stripping techniques combined with an adequate replication policy across the Grid offers the possibility to improve significatively data access and processing times, while eliminating the need for local data mirroring, so saving significatively on storage costs. First results on a local cluster following a simple strategy are presented.

The spectrum of eigenenergies of a quantum integrable system whose hamil-tonian depends on a single parameter shows degeneracies (crossings) when the parameter varies. We derive a semiclassical expression for the density of crossings in the plane energy-parameter, that is the number of crossings per unit of energy and unit of parameter, in terms of classical periodic orbits. We compare the resu...

We compute the boundary entropies for the allowed boundary conditions of the SU (2)-invariant principal chiral model at level k = 1. We used the reflection factors determined in a previous work. As a by-product we obtain some miscellaneous results such as the ground-state energy for mixed boundary conditions as well as the degeneracies of the Kondo model in the underscreened and exactly screene...

I discuss the physics case of the standard Neutrino Factory facility coupled to an iron detector to exploit the so-called ‘Golden-Channel’. The performance of the facility is impressive, although it is not free from degeneracies arising from a combination of physics and instrumental limitations. Nevertheless, one could explore at great depth the parameter of the leptonic mixing matrix as well a...
