In this study, the contaminated anoxic sediment of the Mulde reservoir (Saxony, Germany) was investigated. Several sediment cores were analysed for heavy metals and organic chemicals such as chlorobenzenes and DDTs. The comparison between anoxic and oxidised sediment cores showed the potential danger for heavy metal (Zn and Cd) remobilisation from sediment(More)
In this paper, we show statistical analyses of several types of traffic sources in a UMTS network, namely, voice, video, and data sources. For each traffic source type measurements were collected in order to, on the one hand, gain better understanding of the statistical characteristics of the sources and, on the other hand, enable forecasting traffic(More)
Traffic shaping effect may have significant impact on end-to-end Quality of Service (QoS) provisioning. Therefore, it should be carefully studied in order to allow the creation of appropriate traffic models to be used for simulations. First, to demonstrate the traffic shaping effect, we present statistical analyses on real-time measurements of diverse(More)
A comparative study of polyconidin effects in the replicative and transcription activity of hepatocyte DNA in intact animals, and on peculiarities of spatial organization DNA in the DNA complex with oligomer-25 conidin was carried out. It was shown that polyconidin binding to DNA results in "cross-linking". This process is accompanied by formation of(More)
Protamines areused in clinical practice for rapid and adequate neutralization of the anticoagulant effect of heparin as its antagonists introduced into the bloodstream [3, 13]. They are nucleic proteins of sex cells of fishes with a relatively simple structure and with a very high content of the essential amino acids, in particular arginine (60-70%) [1-4].(More)
The comparative study of the antiheparin activity and acute toxicity of the commercial preparation stellin and its homogeneous fractions was carried out. The summary preparation stellin along with a low antiheparin activity possessed a high toxicity explained by the content of ballast proteins of the nonprotamin nature. One of the homogeneous(More)
Protamines are the major nuclear proteins in the sex cells of fish. These proteins are used in medicine as the substances capable of prolonging the action of various drugs and as the anticoagulants. Protamines of the fish spermatozoa typically contain two to four components having different biological activities. Moreover, it was established that the(More)
