The paper presents observations of solution of the sustainable forestry problem in terms of the Arkhangelsk region. One of the sustainable forestry guidelines is appropriate restraining of the forest harvesting. The volumes of logging in the Arkhangelsk region constitute about half of the allowable wood removal. One of the reasons of the harvesting volumes insufficiency is low density of forest roads network, therefore the accessible areas alongside the existing roads are depleted. The forest roads network should ...

In industrial plants many types of combustible dusts are generated, processed, handled and stored. When ignited, they can burn rapidly and with a considerable explosion force, when mixed with air in proper proportions. This is the reason why adequate precautions have to be adopted, to ensure that all equipment and protective systems are appropriately protected so that the security level from these installations to be high. The establishment and implementation of protection measures is primarily aimed at preventing...

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...

In special applications it is necessary to correlate the obtained data about the state of a process in which the Joule effect is involved by passing an electric current through a conductive material. The multiplier effect due to increased resistance with temperature may require particular attention in monitoring the process, thus requiring automatic decision-making processes so that the modification of the conductive material properties does not affect the entire chain of the process. We propose a system for monit...

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 ...
