    • Abstract in Polish Można rzec, że przy tworzeniu archiwum przez konkretne instytucje wybór oprogramowania to kwestia mniej istotna w porównaniu z tym, czym jest przekonanie pracowników naukowych do umieszczania swoich prac repozytorium. Namówienie autorów do samoarchiwizowania tekstów w archiwach jest wielkim wyzwaniem, jednak nie mniej ważny jest wybór oprogramowania, który poważnie wpływa na jego akceptację w środowisku naukowym. Niniejsza prezentacja przedstawia pewne wymagania wobec oprogramowania i organizacji całego przedsięwzięcia, aby mogło ono być zaakceptowane i użytkowane przez naukowców oraz administratorów (autor podaje przykład z Uniwersytetu w Lund). Ponadto praca zawiera krótki przegląd oprogramowania służącego do tworzenia repozytorium instytucjonalnego wynikający z naszych doświadczeń.

    • Since the mid 1970's, when Adey discovered that extremely-low-frequency electromagnetic field (ELF EMF) may affect the calcium ions efflux from various cells, bioeffects of non-ionizing radiation (NIR) have become the subject of growing interest and numerous research projects. At present, the fact that NIR exerts both stimulatory and inhibitory effects on different physiological cellular parameters is rather unquestionable. At the same time, some epidemiological studies suggest that exposure to EMF is potentially harmful even if its intensity is very low. It has been proved that thermal factors are not responsible for these effects, therefore nowadays, they are called 'non-thermal effects'. Our paper deals with three different aspects of biological effects of non-ionizing radiation, bioelectromagnetism, electromagnetobiology and electromagnetic bioinformation. Firstly, we describe how EMF and photons can be produced within a living cell, how biological cycles are controlled, and what are the features of endogenous electromagnetic radiation. Secondly, we discuss various facets of external EMF interactions with living matter, focusing on extremely-low-frequencies, radio- and microwaves. Possible mechanisms of these interactions are also mentioned. Finally, we present a short overview of current theories which explain how electromagnetic couplings may control an open and dissipative structure, namely the living organism. The theory of electromagnetic bioinformation seems to explain how different physiological processes are triggered and controlled, as well as how long-range interactions may possibly occur within the complex biological system. The review points out that the presented research data must be assessed very carefully since its evaluation is crucial to set the proper limits of EMF exposure, both occupational and environmental. The study of biological effects of non-ioinizing radiation may also contribute to the development of new diagnostic and therapeutic methods.

  • Elektrosmog jako czynnik zagrozenia zdrowia: źródła sztucznych pól elektromagnetycznych, ocena ryzyka zdrowotnego, metody zapobiegania
  • 1997

    • In recent years we have observed how electromagnetic (EM) radiation enters our daily life. The strength of man-made EM field is often far above the natural level and this finding has encouraged a large group of researchers to investigate its possible health effect. Non-ionizing radiation and extremely low-frequency electric and magnetic fields have been the subject of intensive theoretical and experimental works since Adey published his observations concerning non-linear and non-thermal biological effects. At the same time an epidemiological material appeared suggesting that EM field generates various diseases including leukemia and brain tumors. Possible mechanisms of EM field interactions with living matter remain unknown although theoretical models have been proposed by many authors. In vitro and in vivo studies as well as epidemiological data have not provided the ground for decisive conclusions. Nevertheless, the relationship between EM fields and biological effects seems to be most likely. Any international standards for safety limits have not as yet been established and regulations in this regard vary in different countries. However, occupational and residential exposure to EM field can be efficiently measured using an appropriate equipment and such measurements should become a standard procedure wherever electrosmog is suspected to be a pathogenic factor.
