International Commission on Microbiological Specifications for Foods Commission Internationale pour la Définition des Caractéristiques Microbiologiques des Aliments
In early August 2013, a New Zealand dairy company announced that a whey protein concentrate it produces for infant formula, beverages and animal feed was potentially contaminated with Clostridium botulinum, leading to recalls of infant formula products. Although there have been no reports of any public health consequences from this incident, it has raised the level of concern for the safety of ...

متن کاملGlobal Dynamics and Ephemerides
When speaking of Gaia it is instructive to remember the first ESA mission dedicated to high precision astronometry HIPARRCOS launched in August 1989. HIPPARCOS can be considered as Gaia’s precursor, indeed the observing strategy aspects are similar and both missions were designed specifically for high precision astronmetry. After three and a half years of observations HIPPARCOS produced three c...
متن کاملMartian satellite orbits and ephemerides
We discuss the general characteristics of the orbits of the Martian satellites, Phobos and Deimos. We provide a concise review of the various descriptions of the orbits by both analytical theories and direct numerical integrations of their equations of motion. After summarizing the observational data used to determine the orbits, we discuss the results of our latest orbits obtained from a least...
متن کاملGravity tests with INPOP planetary ephemerides
In this paper, we present several gravity tests made in using the last INPOP08 planetary ephemerides. We first propose two methods to estimate the PPN parameter β and its correlated value, the Sun J2 and we discuss the correlation between the Sun J2 and the mass of the asteroid ring. We estimate possible advance in the planet perihelia. In the end we show that no constant acceleration larger th...
