The aim of this study was to investigate the homogeneity of the traditional dry sausages manufactured in small scale facilities from the Massif Central region in France by taking into account the diversity of the production in this area. The homogeneity was estimated by analysis of the physicochemical parameters of 6 types of traditional dry sausages chosen as representatives of the production ...

For success in science, as well as life, it is sometimes necessary to abandon the plan and embrace serendipity. In 1991, Charles O’Kelly tried, for several frustrating weeks, to separate a golden alga, collected from a New Zealand sheep pond, from a contaminating protozoan. “I was trying to grow the alga and the protozoan would not die. So I thought, this is trying to tell me something,” says O...

The decomposition of unitary representations of a discrete group obtained by induction from a subgroup involves commensurators. In particular Mackey has shown that quasi-regular representations are irreducible if and only if the corresponding subgroups are self-commensurizing. The purpose of this work is to describe general constructions of pairs of groups ? 0 < ? with ? 0 its own commensurator...

In Flora Costaricensis, William Burger of the Field Museum in Chicago considered eight of the Piper species that occur in Costa Rica to make up the P. obliquum complex, and six additional species to be closely allied to it (Fig. 9.1; Burger 1971). Piper calcariformis, an additional species assignable to the P. obliquum complex, was later described by Tebbs (1989). Although Burger did not apply ...

Walking into a McDonald’s restaurant and ordering a Big Mac meal, one used inevitably to be asked whether to ‘supersize’ the meal, resulting in a larger portion of fries and a larger soda to accompany a Big Mac burger. The burger itself would be left unchanged. The key feature of supersizing according to McDonalds is to provide a supersized periphery to an unaltered core. Supersizing according ...
