In the environment are present heavy metals such as Cu2+ and Pb2+. Metal-processing industries, mineral processing, the manufacturers of inorganic products and large scale coal users, such as public utilities are the major sources of heavy metal pollution. These heavy metals are toxic, are non-biodegradable, and they pose potentially lethal risks at high levels. Chemosorption is emerging as a potential alternative to the existing conventional technologies for the removal and/or recovery of heavy metal ions from aq...

Seasonal and interannual variability of the Ekman pumping velocity in the Black Sea is studied based on ERA-Interim reanalysis data of 10 m wind speed for the period 1979?2015. Upward Ekman pumping prevails in the annual cycle due to the predominance of the cyclonic wind curl over the Black Sea. The maximum upward Ekman pumping occurs in winter. In June, the basin averaged pumping velocity is directed downwards. The magnitude and spatial distribution of the Ekman pumping velocity depends on the direction of the wi...

STRUCTURE OF VEREYSKY OIL RESERVOIR FROM AKANSKOYE OILFIELD OF THE TATARSTAN REPUBLIC

(STEF92 Technology, 2019-06-20, E R Barieva)

Show more

The oil fields of the Vereysky horizon (C2vr) are regional oil saturated on the Tatarstan Republic and located in the oil-and-gas-bearing Serpukhovsky-Vereysky basinal complex. In the sections are interbedding of various facial types of limestone with marls, clays, and sandstones. From below upwards along the section, the proportion of the clastic component increases and the carbonate component decreases. In the anticline structure, Vireysky oil-saturated reservoirs form multilayers series. Oil reservoirs are conf...

STUDIES INTO THE RELATIONSHIP BETWEEN THE TECHNICAL, PETROGRAHIC, GAS AND STRENGTH PARAMETERS OF COAL FROM SEAMS LOCATED IN THE UPPER SILESIAN COAL BASIN

(STEF92 Technology, 2019-06-20, Katarzyna Godyń)

Show more

One of the properties of coal, used to evaluate the qualitative features of this mineral, is the microhardness of its particular components (macerals). Unfortunately, that parameter is relatively seldom used in analyses of this substance. Microhardness measurements are mostly used in research into metals, ceramics or composites; they are also sometimes used to analyse minerals and rocks. The objective of the paper presented here was to conduct coal's microhardness tests and to determine the relationship between st...

STUDIES OF ZN-PB SINTER REDUCTION USED AS A BATCH IN IMPERIAL SMELTING PROCESS

(STEF92 Technology, 2019-06-20, M. Bernasowski)

Show more

The article presents research on kinetics of sinter reduction used as a charge in the process of simultaneous smelting of zinc and lead, commonly known as Imperial Smelting Process. The aim of the study was to determine the effect of reductivity of various sinters produced from sulphide raw materials and from waste oxides on the operation of a shaft furnace. Real sinter samples from the sinter plant operating at the ISF furnace were collected for the experiment. The experiment was carried out in a resistance furna...

STUDIES ON SOIL MICROFLORA AND MICROARTHROPOD COMMUNITIES AS SOIL HEALTH AND QUALITY INDICATORS IN URBAN FORESTS IN R?GA, LATVIA

(STEF92 Technology, 2019-06-20, Lı̀ga Jankevica)

Show more

Urban forests play an important role in ecology of human habitats and provide various eco-services. Urban forests improve and maintain air and water quality, act as local refugia for plant and animal communities, hold populations of economically important species (such as pollinators), and act as recreational areas for people and pets. All urban forest organisms are directly or indirectly affected by human activities often leading to changes in biodiversity. The aim of our study was to determine soil microbial bio...

STUDY OF A MINIATURE FOUR-LOOP MICROSTRIP COUPLER BASED ON THE USE OF ELECTRODYNAMIC STRUCTURES

(STEF92 Technology, 2019-06-20, Denis A. Letavin)

Show more

Directional couplers are widely used in microstrip technology, but their dimensions are tied to the operating frequency. Since the smaller the frequency, the longer the longitudinal length of the quarter-wave segments and the greater the overall dimensions of the coupler. For this reason, use miniaturization, which allows to reduce the area occupied by the device on the substrate, with negligible loss in performance. In addition, there is an economy of the material used in the manufacture of the microstrip device....

STUDY OF BAFFLES BASED ON SOFT WATER-FILLED SHELLS IN HYDROSYSTEM TAILRACES

(STEF92 Technology, 2019-06-20, Yulia Kuznecova)

Show more

In hydrosystem tailraces, behind end fixings of spillway facilities, scour basins of considerable depth and length are formed at high rates of the flow. This is associated with the violation of the extreme load mode during the construction and operation of hydrosystems, insufficient design length of fixings in tailraces, and inefficiency of installed baffles. Baffles based on soft water-filled shells are proposed as additional protection facilities of operating hydrosystem tailraces. The morphological analysis of ...
