Opis:: Economically important rye (Secale cereale L.) cultivars are highly susceptible to leaf rust caused by Puccinia recondita f.sp. secalis in Germany. Presently, only race-specific resistances are available, which are likely to lose their effect after prolonged application. To study possibilities of increasing the durability of resistance, a three-year field experiment was initiated in 2000. Seventeen differential lines, three susceptible standards, 30 segregating populations with one to four resistance sources and two full-sib families were grown at six locations under a high level of natural infection. All segregating populations were significantly more resistant than the susceptible standards. The resistance level, however, was under these conditions moderate only. The two full-sib families from Russia showed high resistance. Strong genotype × location interactions were observed indicating different race compositions of the local leaf rust populations.

Opis:: The main questions related to nuclear power development concern effects of small radiation doses typical for the operation of nuclear power plants (NPPs) and hazards of NPP accidents. The last decade has brought many results of large scale epidemiological studies indicating that there are no detrimental effects of low radiation doses. On the contrary, many results indicate that among the people receiving increased radiation doses the frequency of cancer mortality is reduced. The review shows that such results are obtained in the studies of people living in high background radiation areas, of workers exposed to ionizing radiation and of patients exposed to radiation for diagnostic purposes. The latest studies in molecular biology suggest an explanation for possible beneficial effects of low radiation doses. This is reflected in the statements of several scientific bodies and international organizations, although the official regulations remain unchanged. The other important issue is the safety of NPPs in case of accidents. Reasons for the Chernobyl accident are shown not to be applicable to the reactors planned for Poland and the effects of Chernobyl are shown to be much smaller than feared in original estimates after the accident. Polish NPPs will satisfy the requirements of EU utilities and will provide safety for the population even in case of hypothetical severe accidents. Nevertheless, discussion with antinuclear organizations must be expected, although the recent examples of changing attitudes of leading ecological authorities show that nuclear power is gaining recognition as a clean and environmentally friendly source of energy.

Opis:: Niniejsza praca podsumowuje dostępną wiedzę na temat wpływu infradźwięków i hałasu niskoczęstotliwościowego (HNcz) na zdrowie i samopoczucie ludzi. Podstawą tego narracyjnego przeglądu piśmiennictwa były wybrane, głównie recenzowane prace badawcze, artykuły poglądowe i metaanalizy opublikowane w latach 1971–2022. Uwagę skoncentrowano na wynikach badań epidemiologicznych dotyczących dokuczliwości przypisywanej infradźwiękom i HNcz, a także ich wpływowi na układ sercowo-naczyniowy i zaburzenia snu. Szczególną uwagę poświęcono także ostatnim wynikom badań i swoistym źródłom infradźwięków i HNcz, tj. turbinom wiatrowym.
This paper summarizes the currently available knowledge on the impact of infrasound (IS) and low frequency noise (LFN) on human health and well-being. This narrative review of the literature data was based on the selected, mostly, peer-reviewed research papers, review articles, and meta-analyses that were published in 1971–2022. It has been focused on the results of epidemiological studies concerning the annoyance related to infrasound and low frequency noise, as well as their impact on the cardiovascular system and sleep disorders. Particular attention was also paid to the latest research results and specific sources of IS and LFN, i.e., wind turbines.
