Show more

The cement industry, along with metallurgy, electric power, chemistry, and mechanical engineering, determines the economic potential and level of industrial development of any country. The role of cement in modern construction is very large, at the moment it cannot be replaced by anything equivalent. At the same time, cement production is extremely resource-and energy consumption industry, and its production accompanied by a large amount of greenhouse gases. According to forecasts of scientists, emissions of carbo...

THE STUDY AND INFLUENCE OF JOINTING AS GEOLOGICAL FACTOR ON PIT EDGES STABILITY

(STEF92 Technology, 2020-09-20, Sedina, Svetlana, Berdinova, Nagimapanu, Shamganova, Lyazzat, Abdikarimova, Gulnur)

Show more

Regulatory documents of the Republic of Kazakhstan in the field of substantiating the stability of slopes of pit edges are currently at variance with world practice in the design and operation of open-pit deposits. Modern design methods involve the creation of a three-dimensional complex geomechanical model of the field. Such a model contains information on the geological and structural composition that describes the disturbance of the solid mass by folds, tectonic faults, and jointing. It is important to accurate...

Show more

The Danube Delta Biosphere Reserve (DDBR) covers around 580,000 hectares, where the waters of the Danube enter the Black Sea. It is the second largest and the best preserved of Europe?s deltas; its dynamic, relatively wild ecosystem supports a rich diversity of wetland habitats, numerous lakes, ponds and over 330 species of birds and 45 species of freshwater fish [1]. The region has a long history and the DDBR includes a number of Iron Age fortified sites, remnants of Greek and Roman settlements, and early Christi...

(STEF92 Technology, 2020-09-20, Prahov, Nayden, Prodanov, Bogdan, Dimitrov, Kalin, Dimitrov, Lyubomir, Velkovsky, Kiril)

Show more

The aerial imagery has a long tradition of use as a surveying method in underwater archaeology. With the recent development of new technologies, its application has become more versatile and more common. This article will present the use of aerial photogrammetry in the archaeological survey of the submerged heritage of Nessebar, ancient Mesambria, on the Bulgarian Black Sea coast. A major application is the generation of a digital bathymetric model (DBM) of the seafloor, which is reliable and accurate approximatel...

UNCERTAINTIES AND ESTIMATES USING INPUT DATA FOR THE FLOOD PROTECTION OF SMALL FOOTHILL REGIONS

(STEF92 Technology, 2020-09-20, Soltesz, Andrej, Cubanova, Lea, Barokova, Dana, Orfanus, Martin, Danacova, Michaela)

Show more

The article analyses the current state of flood protection of the urban area in the foothill region. Problems of the area were characterized through selected critical points that support the local flood origination. Of course, the flood is a random phenomenon and its behaviour depends on many other factors, such as soil saturation, vegetation cover, river bed channel current state, as well as drainage cuts, soil management, etc. For efficient design of the flood protection measures, it is necessary to have input d...

STATIC ANALYSIS OF THE LOCK CHAMBER

(STEF92 Technology, 2020-09-20, Tvrda, Katarina)

Show more

Lock chambers are structures built on watercourses in places, where it is necessary to overcome sections with a large longitudinal slope. The method of determining the safety of the lock chamber and the static analysis, design and dimensioning of individual structural parts depend mainly on the type of chamber. Different criteria are used for chambers having side walls reinforced by slope, for chambers having walls made of anchored steel sheet piles, for walls on a high pile grate, and again others, for the side w...

The relevance of the work is dictated by extensive environmental pollution in the areas of mining waste storage by chemical elements of 1-3 hazard classes (Hg, Be, As, Fe, Cu, Zn, Cd, Pb, Co, Ni, Mo, Ag, and Sb). The interaction of crushed sulfide-containing wastes with surface waters and atmospheric precipitation contributes to the formation of highly mineralized technogenic solutions with element concentrations exceeding the background and maximum permissible values several orders of magnitude. Land and water re...

PHYLOGENETIC ANALYSIS OF VERTICALLY AND HORIZONTALLY ACQUIRED GENES RESPONSIBLE FOR SALT TOLERANCE OF NITROGEN-FIXING ?-PROTEOBACTERIA

(STEF92 Technology, 2020-09-20, Muntyan, Victoria, Antonova, Elena, Muntyan, Alexey, Simarov, Boris, Roumiantseva, Marina)

Show more

Symbiotic nitrogen fixation is the most environmentally friendly method for the accumulation of biologically bound nitrogen. Nitrogen fixation is carried out by bacteria, including from the class of ?-proteobacteria. Global climate changes lead to an increase of agricultural areas subjected to salinity. Current knowledge about the effect of high-salt stress on nitrogen-fixing symbiotic ?-proteobacteria has the appearance of a puzzle. The genetic mechanisms determining salt tolerance have been studied in the most d...

RISK ASSESSMENT OF THE SOCIAL IMPACT ON ARSON CRIMINALITY BY RM/RA CRAMM METHOD

(STEF92 Technology, 2020-09-20, Kurilovska, Lucia, Mullerova, Jana)

Show more

The paper deals with the quantitative risk assessment approach to the use of the universal quantitative method RM/RA CRAMM. The method is applied to criminality cases related to arson and other cases of environmental insensitivity influenced by social background. The arson statistics recorded in Slovakia are usually hidden behind other reasons of the fire cause. The hypothesis is that there is a certain impact of the social environment on criminality, including arson behaviour. The quantitative method needs quanti...

Show more

The paper focused on the formation mechanisms of the geochemical soil background for a wide range of elements. Three areas in Siberia of the coal mining spoils were investigated. The spoils were recultivated 30 years ago by applying a homogenous layer of loamy bedrock as a potentially fertile substrate and then left for spontaneous revegetation. The assessment was conducted using bulk concentrations of the elements. Since there is no excess in concentrations of heavy metals and radionuclides in the recultivated sp...

One of the main processes of functioning of digital measuring systems is image analysis. For photogrammetric systems, such tasks involve searching, counting the number of objects of a given type, followed by determining their geometric characteristics. The main problem that impedes the direct application of methods is the provision of a given level of measurement error. Methods, depending on their specific combinations and input parameters, can give different results. This is due both to the quality of the image i...

In order to determine the effects of strong earthquakes for a given settlement, it is necessary to solve several tasks in a few stages. The first task is identification of the building stock for the surveyed area. The assessment of the effects of strong earthquakes is based on procedures for integration of seismic hazard and seismic vulnerability of the bearing structures of the building stock. The building stock is divided into three main groups, taking into account the specificity of the building and the availab...
