The evacuation time of occupants in a fire event is a particularly important parameter, both for the development of emergency evacuation plans and in the post-event investigation. To estimate this time, the classic approach uses alarm / evacuation trials. These simulations involve the allocation of human and financial resources and have the disadvantage of not being able to cover a wide range of technically possible critical scenarios. Moreover, it has been shown that in real fire cases, human behaviour can be sig...

This paper presents the geochemical forms of arsenic that are present in bottom sediments of rivers and surface waters under various oxidative conditions. In summer, in the rivers with the high anthropogenic load the redox potential of bottom sediments varies from 78 mV to 255 mV (at a temperature of 16-20?C), which corresponds to oxidative and mixed oxidative-reductive conditions. It is shown that under these conditions arsenic is present in the form of insoluble arsenous acid, partially ionized arsenic acid and ...

Cyanobacteria are the oldest prokaryotes with worldwide distribution. Some of them are able to produce secondary metabolites (including cyanotoxins), which can have different effects on the other phytoplankton species. It is speculated that production of cyanotoxins is an adaptation mechanism of the cyanobacteria to survive in diverse habitats inhibiting the growth of the competing aquatic biota. In certain environmental conditions, bloom forming cyanobacteria may exert rapidly their allelopathic potential and cha...
