The use of corrosion inhibitors in the paint materials is an important task, since inhibitors often cannot be included individually in the paint formulation directly. In this case, corrosion inhibitor having a high affinity to the surface of a substrate and a plasticizing effect in relation to the film-forming base of the formed coating can have a negative impact on its adhesion and physical and mechanical properties. One of the ways to eliminate this disadvantage is the use of immobilized inhibitors, in particula...

It is a certainty that a rock massif is a very complex environment, known only partially; in the laboratory we cannot produce all the details encountered in situ; therefore, most of the properties determined experimentally not fully express their real value that they have in rock massif. As theoretical basis we might consider theory of similitude initiated by Newton, in the sense of similarity that we can establish to the boundary between theory and experiment. Based on this and considering the applicable theorems...

In this article was designated a relation of average values of measured curvatures of mining terrain with their forecasted values. These values were calculated by the use of the Bialek?s formula with the values of its parameters determined from the geodesic measurements results. The average graphs of measured curvatures were obtained on the base of average values of terrain subsidence caused by multi-seams exploitation of hard coal at the great depth. An exploitation was conducted by the use of longwall system, in...

In a practical context and with a tendency to generalize the dependence between monoaxial and triaxial compressive strength of rocks and qualitative characteristics and also properties of connection between the elements that form the skeleton of studied rocks were analyzed. This qualitative connection was highlighted by means of void index and apparent specific weight. The obtained correlation can be generalized to any type of rock, if it takes into account the amount of adsorbed and absorbed water, the direction ...

The volume of generated municipal waste increases proportionally with the rise in population and higher personal consumption by individuals. Municipal waste management requires considerable financial resources and, because all of us generate waste, we all have to contribute our share. In the Slovak Republic, the fees for municipal waste are laid down by Act No. 582/2004 Coll. on local taxes and local fees for municipal waste and minor construction waste. Pursuant to this Act, municipalities issue their generally b...

This research paper seeks to study the phreatic groundwater body from the Buz?u river alluvial fan. This goal is reached by creating a numerical model associated to a previously created conceptual model. The conceptual model was realized in three stages. Initially, a spatial schematization of the hydrostructure was created using the lithology collected while executing the hydrogeological boreholes. The second step consisted in studying the variation of the hydrogeological parameters in the hydrostructure. The para...

Wetland habitats, such as transition mires and quaking bogs (habitat code 7140) and alkaline fens (habitat code 7230), are characterized by the occurrence of species sensitive to the water stress. The prolonged period of water shortage is manifested by a change in the structure of domination, species composition and, as a consequence, the reconstruction of the entire habitat. Due to the fact, that habitat is not homogeneous and varied very much depends on geomorphological position a monitoring of the water stress ...

The management of the ?umava (Bohemian Forest) and Bavarian Forest National Parks have long been working in the field of natural science research. However, visitor monitoring in these protected areas has been given little attention so far. Successful management of national parks must combine the requirements of nature protection with public use. The aim of the paper is to suggest using cross-border socio-economic monitoring variables to increase the satisfaction of visitors to the national parks without jeopardisi...

There is a fact that where surfaces are in contact with relative movement, there is also wear, with these aspects dealing the Tribology. There are other mechanical parts destroyed during functioning by the fatigue of the materials. Usually these two phenomena are studied separately. But there are mechanical systems where these two actions are joined into a single degradation event, leading to a shorter working time for the parts. The study of the tribo-wear as a simultaneous action with the material fatigue, leads...

The enterprises working in shadow economy do not undertake any measures for protection of ecology, do not pay payments for use of natural resources and environmental in the budget though they do harm to a surrounding medium in the course of the economic activity.

According to the experts the IMF, scales of the shadow sector of economy in the Russian Feder...

Originally, walls were of structural or defensive nature and that typology hasn?t changed for millennia. It can be traced back to the evolution of the human species and the shift from nomadic to sedentary societies. Along with technological progress, society development, urban growth and other factors, new challenges were placed on walls. Today, walls are used for protection against environmental risk rather than robberies or military troops. In the paper the basic typology of walls ? the one of territorial protec...

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...

A precise line that can be called a coastline cannot be determined due to the coastline paradox. However in general terms, coastline or seashore is an area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. In port areas, where port berth is a stable structure, determining the coastline is easy given that the coast structure is defined by vertical bank. Other examples of stable port structures include: slipways, cliffs and solid borders between water and ...

The article proposes an air quality monitoring system in subway stations (possibly in trains) considering that air intake is made in many stations at ground level where the level of noxes (PM, CO2) is high. The proposed system uses sensors for air quality, presence of toxic gases, smoke and fire protection, monitors air quality and permanently provides this information to travelers either by accessing a site and / or locally via a graphical interface. Environmental monitoring information systems are systems of sur...

The progress (evolution) of a civilization based on natural resources development has resulted in permanent natural environment destruction. By the beginning of the third millennium it has become evident that exploitation of the planet's mineral resources, being the basis for the existence and progress of civilization, is the cause of the global environmental crisis. The Mining Institute has substantiated a methodology of restoration of natural ecosystems (ecological restoration), which consists in using an idea o...

Mining is one of the most devastating forms of meeting human needs. As it is clear from the aerial photographs, the landscape of the north-western part of the Czech Republic is highly affected by the activity of the mining industry, namely lignite quarries. During the activities at these quarries, the landscape is transformed into a form that resembles the surface of the moon. For this reason, the law imposes an obligation on mining companies to reclaim the landscape after their activity to guarantee the higher cu...
