Risk assessment of biocides in roof paint. Part 1
PublikacjaSzereg pokryć dachowych, jak farby dachowe, zawiera w swoim składzie biocydy. Dotychczas nie wiadomo do jakiego stopnia biocydy wymywane są z farb dachowych, a ponadto jakie ich stężenie może występować w systemach zbierających wodę deszczową. Zbadano podatność na wymywanie biocydów z różnych niemieckich farb dachowych oraz oszacowano ich stężenie w zebranej wodzie deszczowej

Ordinal pattern statistics for the assessment of heart rate variability
PublikacjaThe recognition of all main features of a healthy heart rhythm (the so-called sinus rhythm) is still one of the biggest challenges in contemporary cardiology. Recently the interesting physiological phenomenon of heart rate asymmetry has been observed. This phenomenon is related to unbalanced contributions of heart rate decelerations and accelerations to heart rate variability. In this paper we apply methods based on the concept...

An Integrated Approach to an Assessment of Bottlenecks for Navigation on Riverine Waterways
PublikacjaWater transport, both sea and inland, is the cheapest, least invasive, and safest option for non-standard loads; hence, it is important to increase the percentage share of inland waterway transport on the rivers of Central and Eastern Europe. Transporting cargo is particularly difficult on shallow waterways because rivers overloaded with sediment determine the vertical parameters on inland waterways. A ship’s safe manoeuvrability...
