QUANTIFICATION OF BORDER EFFECT ON DIFFERENT TYPES OF BORDERS: CASE STUDY OF THE CZECH REPUBLIC

(STEF92 Technology, 2017-06-29, Emil Drapela)

Show more

Border effect is a phenomenon that adversely affects the development of the regions. It involves the suppression of links between centers, which limits the development of the areas between these centers. Each type of boundary is generating variously powerful border effect, which can be quantified as the ratio between the expected and actual power of spatial interactions. Expected power of spatial interactions is calculated on the basis of geographic application of the gravity model, calibrated by using data on dai...

RESEARCHES CONCERNING THE POSSIBILITY OF CULTIVATING ENERGETIC WILLOW ON DEPOSIT OF ASH FROM THERMAL POWER STATIONS

(STEF92 Technology, 2017-06-20, Marin Soare, Paula Iancu, Ovidiu Panita, Rodica Soare, Elena Bonciu)

Show more

Energetic crops are increasingly used as renewable sources of energy as well as for their ability to fix and accumulate carbon in the soil. Willow culture for biomass promotes rural development and environmental protection, especially if it is established in areas less favorable for agricultural crops. Researches from this work has been carried out in a wide range of genotypes of Salix sp. cultivated on a deposit of ash resulting from coal burning to Isalnita Power Station, near Craiova, Romania, over a period of ...

(STEF92 Technology, 2017-06-20, Nicolae Ciont, Mihai Iliescu, Krzysztof Blazejowski, Marta Wojcik-Wisniewska)

Show more

The main purpose of this research is to analyse the influence of different natural aggregate sources, as well as different bitumen types, on the adhesion and affinity between the two materials and on the properties of stone mastic asphalt (SMA). The aggregates used in this study were both fine (sand 0/4) and coarse (4/8 and 8/16), extracted from four different natural rock quarries in Romania, selected after a geographical, geological and geomorphological analysis. From a petrographic point of view, the rocks extr...

RESISTANCE OF WHEAT INTROGRESSIVE FORMS TO HEAVY METALS

(STEF92 Technology, 2017-06-20, Tamara Tazhibayeva, Aigul Abugalieva, Kenebay Kozhakhmetov)

Show more

Wheat resistance to heavy metals (HM) is an urgent ecological problem and it can limit crop production around the many countries in the world. HM is considered as an environmental factor of the anthropogenous nature which influences growth and development of wheat. New approaches are focusing on using of a genetic pool of wild-growing types of crops as an introgressive genetic material for increasing wheat adaptability to HM. In the model, laboratory tests of HM influence on wheat growth used the grain yield of 20...

RESOURCE-SAVING COMPUTER TECHNOLOGY FOR OIL AND GAS EXPLORATION

(STEF92 Technology, 2017-11-20, Petr Martyshko, Igor Ladovskii, Denis Byzov)

Show more

Geophysical data interpretation methods are very important for the study of the EarthпїЅs internal structure and gas and oil exploration. In this paper we offer a method to interpret gravity anomalies (identification of the local density of inhomogeneities) based on new grid algorithms: a three dimensional density distribution is constructed as grid functions by identified anomalies from the sources split along horizontal layers. Algorithm is based on new grid techniques of 3D gravity inversion. The initial approx...

Due to high quantities of animal fat resulted from leather industry, the necessity of a solution in order to neutralize the negative effects that appear by their discharge into the nature has led to continuous research in order to obtain the most suitable one for solving the environmental issue with energy recovery. Between combustion and chemical treatment, the combustion has been chosen in this study as being the most effective one, by technical and economical criteria. Before this combustion, there were perform...

REVERSE MODELLING OF MICROSEISMIC WAVES PROPAGATION FOR THE INTERPRETATION OF THE DATA FROM HYDRAULIC FRACTURING MONITORING IN POLAND

(STEF92 Technology, 2017-06-20, Michal Antoszkiewicz, Mateusz Kmiec, Marek Szkodo, Robert Jankowski)

Show more

A hydraulic fracturing job was performed to stimulate gas flow from a horizontal wellbore located in Poland. The whole operation was overseen by means of microseismic monitoring. For this purpose, an array of 12000 geophones was deployed on ground in form of patches distributed unevenly in a region of 4km from the wellbore. The array was constantly recording seismic signals during whole fracturing processed. Such recorded signals can by analyzed to locate, both in time and space, events connected to cracking rocks...

Show more

The current hard-to-recover oil reserves in Russia stand for more than 60% of total recoverable oil resources. These kind of reservoirs with acceptable technical and economic indicators are extracted only by applying physicochemical recovery techniques. Thus, an important relevance is given to selection of most effective EOR technology, which is directed to decrease the residual oil saturation in rock formations. Various chemical reagents including composites based on water-soluble polymers are injected both in Ru...

Opinions on the potential uses of risk analysis and environmental impact assessment (EIA) are different. Although many experts, researchers, practitioners and policy-makers agree that risk analysis is a valuable tool to inform decisions, they disagree about the extent to which risk estimates may be biased and should be allowed to influence public policies to protect health and the environment and to be used within the EIA process. The quality and value of any risk analysis depends on the adequacy of the data and t...
