Rare-earth elements have countless applications in electronic devices that use state-of-the-art technologies. Experimental research is aimed at making it easier to find them, by predicting their behavior in the processes that form mineral ores.

Alona protzi is a rare species of Cladocera, occurring in lake littoral throughout Europe. However, little is known about this animal, and so far it has not been included in provisional lists of species found in Finland. In this short report we present our findings of Alona protzi, both recent and subfossil material, as well as one previous, unpublished finding site of the species in Finland. We found three subfossil shells of this species in the bottom sediments of two lakes. In a third lake we found intact animals, an ephippial female and a male, while sampling stony bottom of lake littoral.

The author presents Professor LeonardŁukaszuk's position on the problems ofPoland's maritime policy. He discusses the dispute between the People's Republic of Poland and the German Democratic Republic over the delimitation of territorial waters in the Gulf of Pomerania - a dispute which arose between 1988 and 1989 and in which Professor Łukaszuk played a role. Professor Łukaszuk's principal area of interest, which he has presented in Maritime Assemblies, is the issue of the development of international co-operation between Poland and the countries of the Baltic region. All Professor Łukaszuk's papers, although based on scholarly-legal argumentation, have always also had a political dimension. Taking as his basis the position that Poland has a right to ,,husbandry of the sea", Professor Łukaszuk has always involved himself fully wherever Polish rights and interests have been threatened.
