Nutrition and Health: Dairy and Health – the Connection, International Dairy Federation (IDF).. They are subjects of intensive research, notably for their associations with

cations and the baseline influence traces for all repre- sentative inputs, Snap uses hierarchical agglomerative clustering [28] to classify each executed basic block as

In addition to the previous results displayed by ellipsometry coupled with water sorption, water vapor sorption measurements at 25 °C were carried out using a sorption microbalance

As a consequence of this competition between capillary retraction and solidification, the different shapes adopted by the frozen drop depend on the impact parameters and the

Under anodic polarisation, traces of CO were observed as well as a small increase of propylene content which can be explained by partial oxidation and oxidative dehydrogenation

The catalytic behaviour along time of depolished BITAVOX and BINIVOX during the oxidation of C 1 to C 3 alkanes is very close to that observed during the oxidation of C 3 H 8

Despite the favorable properties of Nafion N115 and NRE212 membranes for fuel cell applications, as illustrated in Chapter 3, one of the major issues is the
