The chemical composition of rainfall over the territory of Northern Kazakhstan ? the main agricultural region of the Republic is analyzed. On average for a year, precipitation belongs in neutral type, however for the vegetative period the relation of acid-forming anions to neutralized cautions in most cases is less than one, i.e. predisposition to acidification is observed. The amount of the sulfur, which is dropping out per unit area, is considerable. On the most part of the considered territory, it several times...

In water bodies of the Upper Silesia and D?browa Basin region (Southern Poland), shore processes should be considered on a micro scale owing to the small area of these lentic water bodies, especially when compared to large bodies of water around the world. Intensive geomorphological changes manifest themselves as abrasional forms (e.g. cliffs, terraces), which are found in small numbers on the banks of reservoirs impounded by dams and are more numerous within flooded mineral workings. On the other hand, accumulati...

Synthetic polymers play an important role in the agricultural use as structural materials for creating a favorable environment for plant growth.

When building the foundations of a machine tool, demands must be placed on high quality and, above all, on their stability during their entire lifetime. In practice, however, it shows that these requirements are not always fully met on the customer?s side when laying foundations. In the course of working, these foundations are subsequently damaged and their uneven decline occurs, which results in a change of the machine alignment, and thus it also influences the accuracy of production. For the supplier of the mach...

The GNSS satellite technology is most commonly applied in the area of air, sea or land navigation.

The research experiment was conducted on the example of a Pathfinder Nissan car. In addition, on the rooftop of the Pathfinder...

The development of software (information systems in particular) is a time-consuming process. As statistical research shows more than half of the projects on the creation of information systems are not successful (there are some difficulties, or not implemented at all). All existing approaches consider the development of the system from the point of view of the objective concept, which represents the system as "a set of elements and relations between them." This leads to the problem of transition between the stages...

Groundwater constitutes the largest reservoir of freshwater in the world, representing more than 97% of all freshwater reserves available worldwide (excluding glaciers and ice caps). The remaining 3% is composed mainly of surface water (lakes, rivers, wetlands) and soil moisture. Until recently, attention for groundwater referred mainly to its use as drinking water (eg approx. 75% of people in the European Union depend on groundwater for water supply), but also it was recognized that they are an important resource...

The condition of underlying rock and footing masonry affects significantly technical condition of historical monuments. The caused subsidence may affect the origin of construction cracks, which may directly influence its stability. These impacts are mostly indirect and they are difficult to identify due to information lack. Footing masonry and long-term changes in the underlying rock are hidden underneath existing ground and floor level. If records related to foundations do exist, they are frequently fragmental. M...

The abundances of invasive plant species in the vegetation have negative impacts on the integrity, structure and function of autochthonous ecosystems. Invasive species act as stressors for plant communities and change their species compositions. In the Czech Republic, Ceratophyllum demersum is a species that may represent a risk of invasiveness, particularly in shallow types of water bodies. It is autochthonous is all continents, but it is primarily centred into warmer parts of the mild climate of the northern hem...

Pineapples and mango fruit are consumed fresh, cooked, juiced and also can be preserved. The aim of the study was to evaluate some physicochemical characteristics (pH, total solub...

The concern about the environmental contamination by 241Am is caused by the fact, that its half-life period is longer and its mobility is much higher than that of parent plutonium. That is why in soils and sediments the specific activity of the radionuclide increases over time. The alpha-decay energy of 241Am and the relatively short lifetime of the isotope create high specific radioactivity and thermal yield. In bottom sediments, the ratio of 241Am to 241Pu increases every year. All these factors result in a high...

The upper part of the Tatarstan Republic section is complexed by sedimentary of multi facies complexes of Middle Upper Permian, Mesozoic and Pliocene-Quaternary rocks.

Sulphate precipitation from mine water as ettringite, Ca6Al2(SO4)3(OH)12·26H2O, is generally indicated to be implemented as a second treatment step, following the heavy metal precipitation or as a third step, after gypsum seeded crystallization. The whole process may be seen as complicated by the operators, which always prefer simpler flow sheets, with fewer steps and with lower investment cost, but this treatment process sequence is justified by sludge management depending on type and by the economic reasons rela...

This article discusses the use of different algorithms for analyzing data obtained by magnetic measurements in archaeological excavations. The aim of this work is the automatic detection of possible anomalies in data that may indicate the presence of archaeological sites. The article discusses two kinds of anomalies ? useful (caused by the presence of archaeological sites) and spot anomalies (caused by the presence of various metal debris). Spot anomalies create local noise that interfere with the determination of...

Mortars and colored concrete are used in construction for the execution of masonry blocks, tiles and other building elements and materials that complement the aesthetic appearance of buildings, contributing to their architectural finishing. Pigments are usually used for coloring of the mortars and concretes based on cement mineral. The organic pigments are used in a more limited extend for this purpose. The life time of the facades realized with silicate cement largely depends on the compatibility between pigment ...
