    Notes: The article presents the labour relations evolutions in five sectors (postal services, telecommunications, electricity, railways, air transport) and in six countries (Great Britain, Germany, Sweden, Italy, Spain and France).True convergences appear in the management and administration of employment, in human resources management and in social law. However, sectoral diversities exist and national specificities remain strong: each country ’s situation is marked by different national traditions and influenced by the States’ choices. The State appears as a key actor of changes, too often forgotten.Trades union resistance, which varies considerably according to country, represents an important risk for enterprises if they lead to the postponement of necessary changes. But it may also be the chance to ask the right questions, among which are: the future of public utilities in Europe, the possibility of considering a social project for public services enterprises, the place of law in social regulation and the labour law evolution. The choice is doubtless between a pure adjustment of the market law and “a re-institution of the labour law” by changing the central reference from the employee to a worker having the right to move from one work situation to another (A. Supiot).

    Notes: The feeding experiment was designed on the basis of food allowance rather than on feed formulation. Food allowances are fixed in an attempt to provide the desired amount of nutrients per body mass of fish per day (g* kg−1* d−1 or J* kg−1* d−1). Therefore, the initial determination of optimum feeding ration is not required, and utilization of neutral feed complement (e.g. cellulose) is unnecessary. Data interpretation for such a design study is presented by a sample experiment for protein-energy requirements of a tilapia species, Sarotherodon melanotheron. The interrelationships of commonly used indices for growth and nutritional efficiency are discussed.

    Notes: Abstract The development and characterization of channel waveguides using wet-process, low temperature sol-gel chemistry is described. Two structures have been developed. The first one is a one-layer structure, composed of a sol-gel solution which is a mixture of photopolymerizable organosilicate and organozirconate precursors. The other is a multilayer structure with a buffer under the guide and a protective coating. The layers are deposited by the dipping technique. The devices are obtained by UV light exposure of the coating through a predefined mask (channel waveguides). The refractive index increase is sufficient enough to allow the use of waveguides in the 1.55 μm telecommunication window. These waveguides are thick enough to reduce the coupling losses with an optical fiber below 0.5 dB. Also, because of our sandwich structure, the propagation losses are less than 0.1 dB.
