In different climatic and hydrological regional studies, data from grid databases that cover the climatic data of larger areas can be used. The authors of this contribution are interested in the region of Central Europe, where they can use the publicly available CarpatClim and ECA&D databases for such needs. The first mentioned database provides better spatial detail of the data, but the data is available only to the year 2010. On the other hand, the EC&D database is continually updated (up to the present), but th...

Due to the flow behavior complexity, the calculation of local head losses needs to be based on experimental results. Although there is great literature regarding the study of valves, and a part of it contains detailed results of local head loss too, these values are always related to a specific manufacturer. This means that for accurate design it is recommended to know the specific head loss exactly for the used device. In the present paper the conception and building of an experimental stand for measurement of lo...

Pigments of the inhibitory type are the active principle of most primers used to protect metals from corrosion. Developers of anticorrosive paint and varnish materials seek to replace chromium-containing pigments, which widely used until recently due to their toxicity, with more environmentally appropriate choices. These include ferrite pigments. It is known, that the most spread method for the synthesis of ferrites, which are complex oxides or salts of ferrous acid, is the joint calcination of iron oxides with ox...

The article deals with the prediction of deformation progress of the basement for a high-rise building founded in a deep foundation pit of 12.0 m below the ground level. Foundation consists of a stiff reinforcement concrete raft with basement in a Neogene layer of several ten metres. The deformation progress of the footing bottom is predicted by numerical approach of a finite-element method and the results are subsequently confronted with geotechnical monitoring. For this purpose, the input parameters were calibra...

Twenty eight onshore mud volcanoes of the Kerch-Taman province were analysed to evaluate their current contribution to the trace-element budget of the landscape.

Early Miocene in the northern deep-water margin of the Parathetis ocean. The Maykopian Fm. mudrocks are main sources of solid matter for numerous mud volcanoes of the region. Mud masses (30 samples) and mud volcanic ...

This paper proposes a forecasting model based on time series technique for solar energy generation. The increasing use of renewable energy from solar and wind sources has gained acceptance and is being increasingly used. The main problems with these energies sources are the dependence of power output on the environmental parameters and the circadian variation. In order to obtain a continuous time series, average daily specific power records, W/m2, are used and moving average and exponential smoothing were tested t...

In-Situ Combustion is one of the most important and promising methods for enhancing oil recovery for both light and heavy crude oils from reservoirs. In this method air is injecting into the oil reservoirs and causes ignition and in the next step it effects combustion inside of reservoirs. Nuclear Magnetic Resonance (NMR) spectroscopy as a fast and accessible technique was used to monitoring the light and heavy crude oils oxidation behavior. Herein, we investigated two light and heavy crude oils based on temperatu...

The Oka carbonatite complex, one of the Cretaceous Monteregian Hills intrusions, consist of a wide range of silicate and carbonatite rocks (e.g. sovite, urtite, ijolite, jacupirangite, okaite). In the 60s, due to the abundance of pyrochlores and Nb-bearing perovskites, niobium mine (St. Lawrence Columbium mine) was developed and active until its closure in 1977, however significant amount of niobium minerals still remain at the deposit and surrounding dumps. Besides economic value as a niobium ore (and potentially...

Temporary condition of water resources in the world, the prospects for their security of countries are a matter concern. The world situation with water resource is clearly not satisfactory and remains disturbing in general. In many regions there is co-quantitative depletion of water resources, their deficit becomes increasingly stressful. It is given the modern availability of fresh water in Europe. Russia occupies a leading position according to the total volume of freshwater. However, it is experienced a signifi...

Spatial databases collect information about geographic objects that represent real world phenomena. Stored and shared data sets are not homogeneous, because they are obtained on the basis of diversified source materials. Distributed sources of spatial data are characterized by a different organization in terms of completeness, consistency and accuracy. In Poland, the topographic objects database (BDOT10k) is one of the basic databases covering the entire country. The positional accuracy is a basic element of the s...

The soil is a major reservoir for carbon (C) in biosphere, containing globally twice as much C as the atmosphere and three times as much as vegetation. Soil CO2 efflux is highly sensitive to changes in surface temperature and relatively small changes in surface temperature may have a major influence on the magnitude of soil efflux. The potential increase in CO2 release from the soil caused by future elevated temperature may have a positive feedback effect on the atmospheric CO2 and global changes. For estimation o...

It is obvious that the presence of microfractures in a porous medium increases its permeability. What is unclear is the magnitude of this effect, as it cannot be calculated directly. With the assumption that the fractures are small channels, it is possible to calculate the permeability of a fracture at a given state. In 2018 Pasztor proved that under laboratory conditions the flow will be laminar in the channels, hence the fracture density can be easily determined from simple laboratory measurements (with the ?per...

This paper presents and supports a speculative hypothesis, the essence of which follows. When continental margins in zones of convergence are buried beneath thrust sheets, fluids expelled from the margin sediments travel into the foreland basin and the continental interior. These tectonic fluids have key roles in phenomena such as faulting, magma generation, migration of hydrocarbons, transport of minerals and metamorphism. The thrust sheet, crudely speaking, acts like a great squeegee, driving fluids ahead of it ...

Lazy Bledowskie well field located in the area of the Upper Silesia, was established in 1959. It consisted of max. 22 wells abstracting water from the Triassic carbonate aquifer (Olkusz-Zawiercie major aquifer). This aquifer is additionally heavily drained by Zn-Pb ore mines. Due to the decreasing demand for water and the deterioration of its quality, wells were gradually excluded from operation and liquidated. Currently, only 2 wells are exploited, pumping approx. 11500 m3 /d. As a result of the overlapping impac...
