Asymptotic Flatness in Rainbow Gravity
A construction of conformal infinity in null and spatial directions is
constructed for the Rainbow-flat space-time corresponding to doubly special
relativity. From this construction a definition of asymptotic DSRness is put
forward which is compatible with the correspondence principle of Rainbow
gravity. Furthermore a result equating asymptotically flat space-times with
asymptotically DSR spacetimes is presented.Comment: 11 page

Alternatives to antibiotic growth promoters in rabbit feeding: a review
[EN] This review is focused on the most studied and developed substances which are commonly knownas alternatives to dietary antibiotics, particularly as far as rabbit feeds are concerned. After a reminder of thereason to be and success of antibiotic growth promoters, and why they lately came to be banned in the European Union, we successively deal with probiotics, prebiotics, enzymes and organic acids. Data on rabbitsare, as expected, quite scarce when compared to species such as pigs and poultry. Nevertheless, theavailable performance results are discussed together with the possible mechanisms of action. Special mentionis made of the effects of these substances on digestibility and caecal activity.Falcão-E-Cunha, L.; Castro-Solla, L.; Maertens, L.; Marounek, M.; Pinheiro, V.; Freire, J.; Mourão, JL.
