THE DESIRABLE DIRECTIONS OF REDUCING AIR POLUTION INDUCED BY LOW-STACK EMISSION IN THE LIGHT OF A SURVEY

(STEF92 Technology, 2018-06-20, Marian Turek)

Show more

The paper raises the problem of reducing air pollution induced by low-stack emission. It is one the most serious problems, especially in such countries as Poland, where the Southern regions belong to the most polluted ones in EU. The objective of the paper is to identify the social expectations towards research projects and other initiatives undertaken in order to stop low-stack emission. The objective was achieved using a survey method. The survey was conducted in 2017 in three target groups: among the participan...

THE METHODOLOGY OF DEFINING GEOCHEMICAL DOMAINS IN CU-AG DEPOSIT (THE LUBIN-GLOGOW COPPER DISTRICT, POLAND)

(STEF92 Technology, 2018-06-20, M. Wasilewska-Błaszczyk)

Show more

The Cu-Ag deposit exploited in the Lubin-G?og?w Copper district (LGCD) in Poland is located in the Permian Rotliegend (sandstones) and Zechstein (shale and carbonate rocks) formations. The three main lithological series are not internally homogenous; within them, a total of 16 individual lithological units can be determined. The differentiation between lithological, mineralogical and geometallurgical ore properties is a criterion used to distinguish between main and individual lithologies in the deposit area. A sy...

THE NEW BUSINESS MODEL FOR THE CIRCULAR ECONOMY: MOVING FROM THEORY TO PRACTISE

(STEF92 Technology, 2018-06-20, Nadezhda Shmeleva)

Show more

The world economy continues to grow . About 9 billion people will live on the planet by 2030. To meet the growing demands for resources, products and services is becoming increasingly difficult. According the World Bank, the volume of solid waste will increase from 1.3 billion tons to 2.2 billion tons per year by 2025, mainly due to the developed countries. The Elen MacArthur fund estimates that the economy loses 3.2 trillion dollars annually in the sector of consumer services [1]. The linear industrial model of w...

THE PHASE LOCKING SYSTEM FOR THE FREQUENCY LOCKING OF LASERS FOR GEOINFORMATICS

(STEF92 Technology, 2018-06-20, Vadim Zhmud)

Show more

Lasers are the most accurate measure of distance increment. Therefore, they are used to detect ultra-small oscillations of rock under the influence of tidal forces [1?6]. This allows identifying the accumulated tensions in the earth's crust. The change in the type of such fluctuations indicates the possibility of earthquakes in the near future, which allows reducing the damage from such catastrophic events, to save the lives of many people. Currently, such systems use frequency locking of two or more lasers to eac...

THE PRESSURE ANALYSIS ON WATER RESOURCES FROM BANAT RIVER AREA

(STEF92 Technology, 2018-06-20, Mihaela Pisleaga)

Show more

Water can be found everywhere and plays an important role in human life and equilibrium of the environment. The agriculture, industry and urbanization have had and have a special impact on the biodiversity and water necessity. To establish the line at which a pressure is considered significant, meaning if due to this pressure the surface water do not reach ?good status? it will be made an analysis of pressure and impact on the recommendation of the Water Framework Directive and national methodologies, but taking i...

THE RELATIONS BETWEEN VEGETAL ORGANISMS AND THE WATER FACTOR

(STEF92 Technology, 2018-06-20, Mihaela Sencovici)

Show more

This study aims to highlight relations emerging between vegetal organisms and water factor. The water input in an ecosystem is realized mainly by: precipitations, water vapors from the atmosphere, fog, dew, underground water, snow melting, springs, river flooding, high flow. The water losses from the ecosystem come from evaporation, transpiration and infiltration down to depths inaccessible to plants. In delineating the relations emerging between plants and the water environment, the roots system has an important ...

THE RELEVANCE OF THE PISA TESTS IN THE DECENTRALIZATION OF THE EDUCATIONAL SYSTEM IN ROMANIA

(STEF92 Technology, 2018-06-20, Marilena Nitu)

Show more

The present paper aims to present the concept of the decentralization of pre-university education in the current context as well as how the benefits of the PISA tests can be capitalized by changing the teaching mode, by adopting the creative and personalized teaching model used by the Scandinavian countries. The decentralization of the pre-university education is the transfer of the authority, responsibility, and resources regarding the decision-making and the general and financial management towards the education...

THE RESEARCH OF PROPERTIES OF COMPOSITE MATERIALS BASED ON PLASTER WITH REINFORCEMENT OF NATURAL FIBRES

(STEF92 Technology, 2018-06-20, Markéta Hošťálková)

Show more

The plaster is one of the most often used materials in the civil engineering. It is applied in the form of plasterboards without any reinforcement, for example, cladding boards are unusable as supporting construction. To improve the mechanical properties of plasterboards, fibrous materials such as cellulose or glass fibre are added. The main purpose of the research is to clarify whether natural hemp fibres or straw could be used as the reinforced materials. The second purpose is to verify the use of non-standard t...

THE RESEARCH OF SEMI-SWEET WINE MADE ON FERMENTED CHAHA FROM KHIKHVI GRAPES

(STEF92 Technology, 2018-06-20, Mariam Khositashvili)

Show more

The paper focuses on the results of the research study of the must and wine of the Georgian, aboriginal, rare variety of grapevine called "Khikhvi". The naturally and artificially (IR) fermented chacha was used in the experiment. The objective of artificial fermentation was to shorten the prolonged fermentation time of the freshly pressed chacha. This excludes the activation of acetic acid bacteria in the chacha under the influence of air oxygen. A rapid redox occurs in the liquid in short period by infrared irrad...

THE RISK ASSESSMENT OF UNDERGROUND UTILITY NETWORKS DAMAGE WITH USING FUZZY INFERENCE

(STEF92 Technology, 2018-06-20, Marek Ślusarski)

Show more

Design risk is an inherent element of construction works, and one of its sources is the spatial data quality. Cases of damage to underground pipes and cables are often the causes of accidents, delays or construction stoppages. One of the directions of research on this risk is fuzzy logic. Fuzzy logic is used to describe complex or poorly defined phenomena that are difficult to describe by using probabilistic methods. The paper presents the method of risk assessment of underground utility networks damage which is b...
