Technological modes of metals direct reduction in an aggregate of jet-emulsion type
Authors: Rybenko I. A. , Roos Hans­-Görg
Published: July 2020

The paper presents the method and instrumental system for modeling and optimizing technological modes of direct metal reduction processes in a jet-emulsion aggregate (JER). Stages of the method are considered. The first one is the problem statement: formation of target conditions, choice of the process type, the task and system of optimization criteria. The second stage includes selection of the object of study: setting parameters of input and output flows, process parameters, stages and subprocesses. The third one includes thermodynamic modeling to assess the final equilibrium state in which optimization problem is solved to determine the best conditions for implementation of the processes of metal reduction from oxides in model systems. The fourth stage is development of metallurgical technology (finding the optimum modes and ways for achieving these modes by specified output stream parameters). And the final one is process optimization in technical and economic indicators. As part of the fourth stage, the complex of mathematical models has been developed that reflects relationship of flows and processes in a metallurgical unit. The structure of instrumental system is presented, in which mathematical models and an algorithm for determining optimal technological modes are implemented. A set of optimization criteria has been developed and a scheme for solving two types of optimization problems are presented: finding optimal conditions for reduction processes in thermodynamic systems and determining optimal modes of direct metal reduction. Application of the method to develop optimal technological modes of direct metal production in a JER-type aggregate is shown: metal production from cast iron and mill scale; direct reduction of metal from dusty ores and iron-containing man-made materials; obtaining manganese alloys from carbonate and oxide ores; processing titanium-magnetite concentrates with an almost complete separation of iron-containing and titaniumcontaining component; and direct reduction of iron with associated production of high-calorie synthesis gas.

Published: July 2020

The article considers issues related to the efficiency of metal melts’ filtration depending on the size of non-metallic inclusions, parameters of ceramic foam filters and their location options. Studies of influence of the main structural elements on the filtration processes of nickel melts during casting in a vacuum induction installation were carried out on low-temperature physical models. Modeling of melt filtration processes is based on the hydrodynamic similarity of the processes of motion of melt flows and nonmetallic inclusions in casting tanks. A modeling technique has been developed, the scale has been determined and a model installation has been made. Influence of the arrangement of filtration and dividing walls on the dynamics of metal flows, non-metallic inclusions and filtration efficiency is considered. The efficiency of nickel melts filtration is described depending on the technical parameters both on the filter itself (effective filtration surface, filter thickness, channel dimensions, number of channels per unit area), as well as on the type and size of non-metallic inclusions, design features of the casting device and filter layouts. It was found that the overall filtration efficiency is influenced by the rate and uniformity of the melt flows’ distribution in front of the filter. To ensure uniform distribution of the melt flow rates, a dividing wall with bypass holes is installed in front of the filter, the location of which and their number was also the subject of research. As a result of the studies, the relationships were established between the filtration efficiency, the size and type of non-metallic inclusions when using vertical and horizontal foam ceramic filters during the casting of nickel melts in an intermediate casting tank of a vacuum induction installation. It was found that with a vertical arrangement of the filter, its efficiency is higher than with a horizontal one. An additional means of increasing efficiency of the filtration system is the use of a dividing wall. The optimal number of holes and the location of the baffle in the casting tank were determined, ensuring a uniform distribution of melt flows along the height in front of the filter and an increase in its operation time.

Published: July 2020

The problem of reducing emissions of sulfur dioxide from the flue gases of coal-fired TPPs is highly relevant for domestic energy in connection with the annual increase in coal production. This article analyzes statistical data in the field of coal mining, describes the current state in the field of gas purification and ash collection in the mining and metallurgical industry of the Russian Federation. To regulate pollutant emissions by stationary sources in Russia, a system of maximum permissible and temporarily agreed emissions (MPE and ENV) was introduced. The country takes part in international programs aimed at protecting the environment from the harmful effects of human activity. Despite the general dynamics of reducing air pollution in the Russian Federation, emissions from mining and metallurgical enterprises only increase. This is due to deficiencies in the technical condition and operation of dust and gas cleaning equipment at electric power enterprises. The main ones are the moral and physical deterioration of the equipment fleet, the need for reconstruction and modernization of devices. The average degree of flue gas cleaning from ash at Russian TPPs is 95.5 %, which is noticeably less than abroad. Efficiency of the gas treatment plants used does not meet modern environmental requirements. The flue gases at our TPPs are not cleaned from sulfur and nitrogen oxides; there are practically no devices for continuous monitoring of TPP emissions. The article provides the rationale for the transition of enterprises to the best available technologies (BAT) in the field of gas purification. The use of a gas conditioning system allows 30 – 40 % reduction in the amount of funds spent on the construction of electrostatic filters. In recent years, in connection with the advent of new technologies for burning coal, filters for the purification of hot gases made of ceramic materials have been created. We have analyzed the state of gas purification and ash collection in the mining and metallurgical industry of the Russian Federation and its impact on the atmosphere. An assessment of the current state of gas purification equipment at the enterprises was carried out.

Strategy of M&A deals in oil industry (on example of «Rosneft» and «Bashneft» deal)
Authors: Astapov K. L.
Published: July 2020

I analyzed merges and acquisitions’ transactions and their influence on strategy and development of oil company. For analyses the deal I chose acquisition by Rosneft of Bashneft, which took place in October 2016, applying both traditional and real option models. Real option model is more difficult, but better methodology, because it allows to valuate different scenarios of acquisition, choose more optimal scheme (acquisition time, amount of acquired shares). After building decision tree I calculated NPV of cash flows, which are generated in the deal (in scenarios of high and low oil prices, high and low synergy effects in two periods 2017–2018 and 2019–2020).

The main results are the following. Acquisition deals create value for shareholders, only if acquisitions correspond to strategy of bidder company and culture of target company. Under some hypotheses the acquisition of Bashneft creates additional value for Rosneft in most scenarios (except scenario with low oil price and low synergy). Postponing the decision about complete acquisition till 2019 increases probability of successful acquisition as well as maximizes NPV.

The authors study the role and the place of the key enterprises of Russian fuel and energy complex in terms of their impact on the most important macroeconomic indicators of national economy development. The crisis of 2014 made significant changes in each company’s activity due to fluctuating ruble’s exchange rate, high inflation, ban on foreign investment, restrictions on international trade, etc. However, the largest companies of Russian fuel and energy complex were able to adjust to external conditions and reestablish their competitive position by the end of the second decade of the 21st century. The authors examined the period from 2014 to 2019 which is remarkable for a number of positive changes in the economic structure ofRussia. Yet, the fuel and energy complex still remains the driver of the economic development. Also, the article studies the role of fuel and energy complex in foreign economic activity in dynamics. The authors suggest the scheme of calculating the contribution of a certain legal entity into the country’s GDP. They made all the relevant calculations characterizing the degree of the mentioned companies’ participation in establishing the most important macroeconomical indicator of the national economy. The results obtained can be of great value in building a company’s strategy, planning taxes, creating investment policy as well as estimating the level of their social responsibility. The authors analyzed the structure of oil and gas income of Russia in 2018-2019 to view the nature of the process which has been going on in budgeting of Russia in recent years and point out the need for increasing the investment potential of fuel and energy complex and altering the degree of government’s participation in in creating the long-term investment strategy of developing national fuel and energy enterprises.

Published: July 2020

Objective: This study was carried out, aiming to analyze the frequency and factors related to dental and maxillofacial findings, caries experience, and oral hygiene status among Kurdish Children with Cerebral Palsy in Sulaimani governorate.  

Methods: This cross-sectional study included 100 cerebral palsy children. They were subjected to extra and intraoral examination for dental and maxillofacial changes after obtaining medical and dental histories. The mean DMF/dmf index, significant caries index, met need index (MNI), restorative index (RI), and simplified oral hygiene index, were recorded. Independent t-test, Chi-square tests, and Spearman correlation coefficient were used to analyze the data, and P-value < 0.05 considered significant.

Results: Nearly half of our cerebral palsy children were delivered by Cesarean section, diagnosed after birth with jaundice and had mental retardation. The premature delivery associated with cerebral palsy types (P=.006). Extra-oral features were normal in 41% of children. Hypertelorism was the predominant facial finding (48%), and 55% showed malocclusion (class II & III). Dental caries was observed in 55% of the patients, mostly in the primary dentition (mean dmft index =3.18) and the significant caries index =8.69. The MNI (=0.455) and RI (=0.412) were higher in the permanent dentition. The majority of children had good oral hygiene. No correlation was found between cerebral palsy and the studied parameters.

Conclusions: Children with cerebral palsy showed a high incidence of dental caries in primary dentition, malocclusion, and surprisingly good oral hygiene, but none of which was correlated to any type of cerebral palsy.

Na početku 19. stoljeća diljem Europe intenziviralo se prikupljanje i trgovanje antičkim spomenicima, bilo za privatne zbirke, bilo za novoosnovane državne institucije. Tim procesima zahvaćena je i istočna obala Jadrana kao bogato izvorište građe. Na temelju arhivskih i drugih izvora u ovom se radu detektiraju putovi kojima su salonitanski spomenici odneseni u današnje talijanske pokrajine Veneto i Furlaniju (Friuli-Venezia Giulia) tijekom Prve austrijske uprave u Dalmaciji (1797. – 1806.). Odatle je dio spomenika preseljen u Carski i kraljevski kabinet za numizmatiku i starine u Beču (Kaiserlich-Königliches Münz- und Antikenkabinett), a dijelu se zauvijek gubi trag.

Authors: Melnyk Liubov , Myronyuk Oleksiy , Ratushniy Volodymyr , Baklan Denys
Published: July 2020

The possibility of industrial waste – alkaline red mud to be used as the filler of glyptal resins and coatings thereof is considered. It was determined that the most effective way of compounding of said components was in situ combinations during the synthesis of the polymer, providing systems with filling factor up to 36 wt.% with decreased moisture absorption ability in comparison to the initial resin. It was demonstrated that the most probable cause of this performance increase is the formation of chemical bonds between the hydroxyl groups of glyptal and weak van der Waals bonds between the carbonyl group of the resin and surface groups on red mud.

Published: July 2020

Mucilage and powder of okra were evaluated as bio-flocculant in water treatment using jar test. The agitations sets, okra preparation methods and the amount of coagulant/bio-flocculant were evaluated in the turbidity removal. The results showed that agitations set of 150 rpm and then 40 rpm were more effective for reducing turbidity. Turbidity reduction was 39% using inorganic coagulant (FeSO4) alone, but reduction came to 76% and 88% by adding okra mucilage and powder, respectively. All results showed that okra powder present better turbidity removal in water treatment. It can be prepared by simple methodology, and also allow the inorganic coagulant reduction in approximately 64 %. In okra powder were identified hydroxyl groups that serve as active sites for colloidal particles removal

Sustainable development of cities and communities is supposed to be based on the innovative technologies, primarily infocommunications. These technologies should be used in the most efficient way, and the population requires proper "smart" competencies and tools to fully participate in the decision making. The article offers the appropriate methodology and the corresponding mathematical apparatus based on the methods of system analysis, mathematical and computer modeling, multi-criteria optimization for making complex decisions. Organizational and methodological procedure for modeling, optimization and coordination of decisions, the mathematical model for the reconciling stakeholders’ interests in making decisions on the urban development, and main design solutions for the city portal implementation that ensures the direct participation of the population in the coordinated decision-making were introduced in this paper. The whole approach is based on the advantages of the universal coefficient method, which allows different stakeholders, regardless of their level of education and training, to express their own preferences in their natural form and immediately see what consequences their decisions lead to. The developed mathematical model is of an optimizing nature and on the basis of the specific measures introduced into it, forms an agreed development plan for the smart city.
Filozofia władzy w ujęciu o. Jacka Woronieckiego
Authors: Skrzydlewski Paweł
Published: July 2020

Ojciec Jacek Woroniecki na kartach licznych swych prac zaprezentował bardzo ważną koncepcje władzy ludzkiej. W koncepcji tej wykazał, że sprawowanie władzy jest działaniem moralnym człowieka, mającym swe uzasadnienie i wyjaśnienie w naturze osoby ludzkiej. Władza ludzka jest, zdaniem Woronieckiego, efektem posiadania przez człowieka cnoty roztropności. Woroniecki wykazywał, że pierwszą szkołą władzy jest zawsze rodzina, miejsce zaistnienia i wychowania człowieka. Dobre uformowanie w człowieku władztwa wymaga przede wszystkim znajomości prawdy o człowieku oraz jego przeznaczeniu, a także formach i sposobach życia. Woroniecki przestrzegał przed licznymi nowożytnymi ideologiami deformującymi ludzką władzę. Całe swe rozważania nad władzą oparł na myśli św. Tomasza z Akwinu oraz na filozofii realistycznej związanej z Akwinatą oraz Arystotelesem.

Wychowanie człowieka w perspektywie personalistycznej antropologii filozoficznej i realistycznej pedagogiki o. Jacka Woronieckiego

O. Jacek Woroniecki, wybitny teolog, filozof, pedagog był zarówno teoretykiem, jak i praktykiem. Wśród wielu kwestii, które podejmował, ważne miejsce zajmowała problematyka wychowania i pedagogiki. Akcentował znaczenie wychowania w życiu ludzkim, a pedagogikę uznawał za integralną część etyki. Koncepcja wychowania i pedagogiki o. Jacka Woronieckiego odwołuje się do realizmu bytowego i poznawczego, dlatego można uznać, że ujęcie to jest nadal aktualne.

W związku z tym, celem niniejszej publikacji jest przedstawienie w aspekcie teoretycznym wychowania człowieka w perspektywie personalizmu oraz przybliżenie koncepcji pedagogiki realistycznej o. Jacka Woronieckiego. Biorąc pod uwagę złożoność tego zagadnienia, zostały omówione tylko wybrane jego aspekty. W pierwszej kolejności przedstawiono antropologiczne podstawy wychowania ze szczególnym omówieniem uniwersalizmu i realizmu pedagogicznego. Następnie ukazano, jak rozumiał i definiował wychowanie o. Jacek Woroniecki, oraz omówiono jego koncepcję rozwoju człowieka – od osobowości do osobistości. Przedstawiono także wybrane działania, które zastosowane w procesie wychowania pomagają człowiekowi w dochodzeniu i osiąganiu doskonałości.

En la STC 27/2020 el Tribunal Constitucional se pronuncia acerca de la ilicitud de ilustrar una crónica periodística sobre un acontecimiento violento con una imagen de la víctima que había sido tomada de Facebook sin recabar consentimiento de su titular. El fallo estima que la publicación de una fotografía en una red social no equivale a una autorización para que terceros puedan hacer uso de la misma libremente y que la divulgación de la imagen de la víctima ni reviste interés informativo por sí, ni guarda relación de accesoriedad con la información contenida en el reportaje, por lo que aprecia la vulneración del derecho fundamental a la propia imagen.Recibido: 07.04.2020Aceptado: 12.06.2020Publicación en línea: 03.07.2020
The Principle of Good Faith in Public International Law
Authors: Uçaryılmaz Talya
Published: July 2020

Honesty, loyalty and reasonableness together refer to the principle of good faith in contemporary private law. The principle of good faith historically emerged as a natural law principle deriving from Roman law of nations, the universal set of rules applicable for all mankind. However, it also has immense historical effects on the early modern theories of international law. Being based on natural law and morality, good faith is well-equipped to be a fundamental standard of behavior in contemporary international law concerns. Good faith manifests itself as pacta sunt servanda as the basis of international treaty law. As a principle referring to honesty, loyalty and reasonableness, it guarantees the prohibition of the abuse of power and provides equitable solutions in legal relationships between sovereigns and private actors. Accordingly this article examines the application of the classical Roman principle of good faith in international law from a transhistorical perspective to clarify its contemporary applications, taking refugee law as an example. It concerns itself with the fundamental elements of good faith, the historical emergence of the principle, its relationship with early modern international legal theories and its contemporary significance in refugee law.Received: 23.10.2019Accepted: 29.12.2019Published online: 03.07.2020
