W pracy przedstawiono właściwości mechaniczne gumy EPDM i NBR o twardości 65 °ShA. Rezultaty w postaci jednoosiowego i dwuosiowego rozciągania stanowią niezbędne dane do przeprowadzenia analizy numerycznej odkształcenia elementów wykonanych z gumy. Do zaprojektowania kompensatora o zwiększonej wytrzymałości wykorzystano analizę numeryczną, bazującą na metodzie elementów skończonych. Numeryczny model kompensatora poddano złożonemu obciążeniu, wyznaczając sztywność w danym kierunku osi oraz dopuszczalne naprężenia gwarantujące bezawaryjną eksploatację kompensatora.

The paper presents the mechanical properties of the NBR and EPDM 65 Shore A hardness rubber. The results in the form of uniaxial and biaxial tension are necessary data to preform numerical analysis of the elements made of rubber. To design of the rubber expansion joint with increased strength the numerical analysis based on finite elements method was used. The numerical model of the rubber bellow subjected to complex load as results determined stiffness in different axial direction as well as permissible stress guarantying its failure-free exploitation.

The nematodes were collected from livers of Baltic cod caught off the Gulf of Gdańsk. This paper consists of a description of the third stage larvae of Contracaecum osculatum (Rud.). This nematode is also pathogenic for man and its occurrence on the Polish coast has epidemiological significance.

Nematodes from the superfamily Ascaridoidea (families Anisakidae and Raphidascarididae) are worldwide distributed parasites. Their live cycles include many species of water invertebrates and teleostean fish as intermediate hosts, and fish, sea mammals or fish-eating birds being definitive hosts. Humans can be infected with some of these parasites after consumption of raw or wrongly processed fish. The parasitological investigations of fish (herring, cod and flatfish) from southern Baltic (ICES 24-26) provided in the years 80 and 90 showed their infection with larvae of several anisakid species: Anisakis simplex s. str., Contracaecum osculatum C and Hysterothylacium auctum. Sporadically Pseudoterranova decipiens and Raphidascaris acus were also found. Larvae of Anisakis simplex were noted mainly in herrings, C. osculatum primarily in cods and H. auctum in flounders. Additionally, preserved herrings (marinated, smoked) were also investigated and sporadically live larvae of A. simplex were found. The main etiological agent of human anisakidosis worldwide is A. simplex. Although the live cycle of this nematode cannot be completed in the Baltic Sea - this nematode is brought to the Baltic by infected herring migrating from the North Sea for spawning in coastal waters of the Southern Baltic - the prevalence and intensity of infection with larvae of this nematode species were the highest in fish investigated by us. The results obtained suggest the possibility of the human infection with A. simplex larvae in Poland.

The identified mutations in the pfcrt, dhfr and dhps genes of Plasmodium falciparum show a very high correlation with resistance to chloroquine, pyrimethamine and sulfadoxine, the drugs that are still used as malaria chemoprophylaxis or treatment. We undertook a molecular screening of 82 Polish P. falciparum isolates, mainly imported from different countries of sub-Saharan Africa to assess their molecular drug-resistance profiles. Only 4 isolates showed no mutations in the three analyzed gene fragments. In the remaining isolates from one to six mutations in one or more examined genes were found. Different mutations in the pfcrt, dhfr and dhps genes were found in ca. 76%, 80% and 70% of P. falciparum isolates, respectively. About forty our patients used chloroquine or pyrimethamine + sulfadoxine as malaria chemoprophylaxis and/or antimalarial treatment, but without success. In all but 5 of the P. falciparum isolates obtained from these persons, mutations associated to resistance of the parasite to chloroquine and the antifolate drugs were found.
