Fires in natural ecosystems, including forest fires, destroy whole ecosystems of states and can be extremely catastrophic. Total square of forest fund in Ukraine is 10.4 million ha, 9.6 million ha of which is covered with forests vegetation. Forest cover of the state is 15.9%. For the last 50 years, the square of the forests increased at 21% and wood stock ? almost three times. Suppression of fires in natural ecosystems and forests would be impossible without transportation means. That is why, during emergency man...

In order to properly manage water resources in a river basin, it is necessary to identify trends in the evolution of rivers flow. Long-term trends analysis for river flow in north eastern part of Romania is based on two different methods: non-parametric rank-based Mann?Kendall (MK) test and innovative trend analysis (ITA). These two methods were applied for 7 hydrometric stations located in river basins unaffected by hydro-technical works, with hydrological observations on the average flow for the period 1950-2017...

Determination of the maximal run off in the constantly changing urbanized territory often is very different compare to the natural conditions. There are many approaches to reflect the new conditions of flows formation including the extremes. Sometimes the level of urbanization is so quick that the conditions of flows formation could be altered in the frame of several years. The determination of the maximum flows is additionally complicated in case there is not a suitable hydrological monitoring network or a lack o...

Wind is by far the most important natural disturbance, shaping the forest composition and age structure in Europe. Birch (Betula spp.) is among the wind-resistant species, especially during the season of extra-tropical cyclone storms, when it typically is in leaf-less state. However, predicted shifts in the frequency and seasonality of storms will affect also this species, therefore modelling of its wind resistance is important. For this purpose, among others, data on wood properties are essential. Typically such ...

At the present stage of the mankind development, oil and oil products receive an increasing role. One of the indispensable in the modern world petroleum products is transport fuel. Up to 89% of the fuel contains components obtained during refining. Despite the tendency of developed countries to increase the share of cars that use diesel fuel, in Russia, most of the share is in cars that use gasoline. The benchmark indicator of commercial gasoline is the octane number - a measure of their detonation stability. The ...

In thisstudy, the influence factor of the vertical movements of the earth's crust was taken into account. Such phenomena are strongly extended in time, but have a greater influence on the hydrographic network, for example, the closest example for the North-West of the Russian Plain is the transfer of runoff from Lake Ladoga from the Vuoksa River to the Neva River. Reconstruction scenarios of flow direction changing is important to improve the safety of the population and sustainable use of territories. The most im...

A serious challenge for the construction of Sofia Metro is the shallow groundwater and the high water abundance of the hydrogeological units that are crossed by the construction route. The dewatering of the excavations for the facilities that are supported on deep foundations and the tunnels is most often associated with large and long-lasting local depressions of the water table. The joint action of the drainage systems around the metro stations and tunnel sections built simultaneously or in overlapping time inte...

Purified natural clinoptilolite as well as clinoptilolite converted into hydrogen and sodium form have been contacted with 0.1 mol/L silver nitrate solution at a ratio solid to liquid equal to 1 to 20, in order to load silver ions (Ag+) on the zeolite support. It has been found that sodium modified clinoptilolite exchanged in highest degree Ag+ ions, followed by natural zeolite. Preliminary transformation of natural clinoptilolite into hydrogen form leads to decreasing of zeolite ability to bind Ag+ ions. The kine...
