The article is devoted to more comprehensive use of medieval onymic resources in research on the history of the Polish language. These materials were used in research on the phonetic development of the Polish language in its earliest period. To date, they have rarely appeared in lexical studies. The body of the oldest appellatives, reconstructed on the basis of proper names, would be a kind of lexicon (supplement) enriching and verifying old Polish lexical material, certifi ed in historical Polish dictionaries (also in etymological dictionaries). In this way, the expectations formulated over 100 years ago by eminent Polish linguists may be fulfi lled. The complementary use of such a huge wealth of material opens up further research perspectives towards etymological, dialectological, lexical and morphological research.

The motion of submicron particles involves the deterministic terms resulting from the aerodynamic convection and/or electrostatic attraction, and the stochastic term from the thermal displacement of particles. The Langevin equation describes such behavior. The Brownian dynamics algorithm was used for integration of the Langevin equation for the calculation of the single fiber deposition efficiency. Additionally the deterministic and stochastic of the particle motion were derived, using the Lagrangian and Eulerian approaches of particle movement and balance, for the calculation of the single fiber deposition efficiency due to both mechanisms separately. Combination of the obtained results allows us for calculation of the coupling effect of inertia and interception with the Brownian diffusion in a form of correlation. The results of calculation show that the omitting of the coupling effect of particular mechanism and using the simple additive rule for determination of the single fiber deposition efficiency introduces significant error, especially for particles with diameter below 300 nm.

The first records from samples from the IceAGE cruise ME85/3 in 2011 include seven species of Caudofoveata with a distribution range in Icelandic waters. From this first cruise of the project, two new records for Iceland have been registered. Psilodens balduri sp. n. is new to science and Falcidens halanychi , with a known distribution in the American North−Atlantic, is new to Iceland. The current study thus increases the number of known caudofoveate species around Iceland to nine.
