Opis:
Parasites of an invasive species, the raccoon dog (Nyctereutes procyonoides) from western Poland were investigated to clarify poorly known ecological key aspects of the species. The research was conducted in two study areas: the Ujście Warty National Park and the Bogdaniec Forestry District. Intestinal samples were collected from the intestinal tracks of 39 dead animals and 51 faecal samples were collected in all seasons from latrines of raccoon dogs. Macro-parasites, their eggs and protozoan parasites were investigated to assess the taxonomic composition of parasites, the level of infection and the risk of potential transfer of dangerous parasites from raccoon dogs to people and native species. Among parasites potentially dangerous for human and native mammal species, Toxocara canis was found in the intestines and T. canis eggs, Cryptosporidium sp. oocysts and Entamoeba sp. cysts were identified in faecal samples. Sarcoptic mange was observed in the skin of two animals, whereas Diptera larvae (probably from the family Gasterophilidae) were found in the intestines of two other animals. This latter finding is very interesting, because Gasterophilidae are the typical parasites in horses and ungulates, but so far were never found in raccoon dogs.

Opis:
Free vibrations of slender systems are the subject of many scientific and research works. In this work, the boundary problem of free vibrations of a compressed column, which is additionally heat loaded, is considered. The issue of heat flow in the column is solved using the Finite Element Method. Averaged distribution of material properties is obtained in individual segments of the column in subsequent heating times. The mathematical model of free vibrations takes into account the thermal expansion of the material and the effect of changing the Young's modulus resulting from the effect of heat load. The boundary problem of the free vibrations of the considered system is limited to the linear range (the linear component of natural frequency is considered). The influence of the heat source exposure time on the course of characteristic curves (on the plane: load – natural frequency) is determined. The results are presented for various column diameters.

Opis:
The outstanding work by Prof. Anna Młynarska-Sobaczewska devoted to an extremely important and pressing issue of the right to culture was based on an extensive source material, which consists of both international, regional (including European) and national normative acts, as well as judicatures of the European Court of Human Rights and national courts. At the same time, the book presents in an interesting way the current state of research and the results of scientific discussions concerning the title issue in relation to the latest publications on the subject. It is noteworthy that during the discussion the author convincingly supported her arguments with an insightful comparative analysis of selected legal systems of European countries. from the review of Prof. Jędrzej Skrzypczak, Ph.D., Adam Mickiewicz University in Poznań
