Comparing strategies against COVID-19: Italy and Switzerland
Authors: Cepiku Denita , Giordano Filippo , Meneguzzo Marco
Published: March 2021

Abstract The COVID-19 pandemic has all features of a wicked problem. It is not only a crisis of intensive care but also a more complex health, social, economic, and humanitarian crisis. Moreover, its risks will continue until mass vaccination is undertaken, hence, the control of contagiousness relies on citizens’ responsible behavior. Strategies to fight COVID-19 in Lombardy, Veneto (Italy) and in Ticino (Switzerland) have shown that a more balanced approach focusing not exclusively on hospitals but also on a territorial basis, pays off. Therefore, a more integrated approach is beneficial from a clinical, social, and economic point of view providing procedures for future emergencies.

Published: March 2021

Abstract In Brazil, sub-national governments have played a particularly important role as the key actors implementing non-pharmaceutical interventions to halt the spread of COVID-19. Building on the methodology proposed by the Oxford COVID-19 Government Response Tracker (OxCGRT), we coded the stringency levels of state-level school, commerce, services, industry, public gathering, and private event closure policies and describe these actions’ duration at the state-level in Brazil from early February to mid-May 2020. Our results suggest significant heterogeneity across Brazil and across weeks in social distancing policy stringency during this period. We then apply dynamic times-series cross-sectional methods to evaluate the effect of anti-contagion policies on the population’s mobility using cell phone location data. We find that anti-contagion policies had a significant effect on producing higher adherence to remaining at home even though social distancing policies were relatively moderate as compared to other countries. Our results also suggest that social distancing policies have a greater impact when a more complete and coherent set of policies were introduced and sustained by state governments.

Published: March 2021

Abstract The large number of less-known coastal drainages in the Atlantic Forest still represents an important gap in the knowledge of ichthyofauna. It is evaluated the taxonomic diversity, frequency and constancy of occurrence, and the distribution of species in the various segments of the Perequê-Açu river basin, state of Rio de Janeiro, Brazil. Twelve sampling campaigns resulted in 13,423 individuals, belonging to seven orders, 10 families, 21 genera, and 23 native species. Cyprinodontiformes and Siluriformes represented about 87.2% of the total abundance, mainly due to the contribution of Phalloceros anisophallos and Schizolecis guntheri, which account for 63.2% of the total sampled individuals. The analysis of constancy of occurrence reveals that 78.3% of the drainage species are residents, with approximately 93% of the residents of the Carrasquinho River sub-basin. The Sertões River sub-basin had the largest number of species in total: 18. The rarefaction curve did not reach an asymptote, although Chao 2 and bootstrap estimate the richness of 23.9 species and 23.7 species, respectively. The results of PERMANOVA, PCoA, and SIMPER indicate that the fish composition along the catchment is not homogeneous. The conservation status of species is also discussed, regionally, nationally, and globally.

Introduction: The variation in the aortic arch is well known and it has been demonstrated by number of researchers. Changes involved in the development of aortic arch system such as regression, retention or reappearance result in the variation in branching pattern of aortic arch. Variations of the branches of aortic arch are due to alteration of branchial arch arteries during embryonic period. The most common classical branching pattern of the aortic arch in humans comprises of three great vessels, which includes Brachiocephalic trunk, Left Common Carotid artery and Left Subclavian artery. Aim: The study is to determine the embryological basis correlating with clinical application and surgical procedures. Materials and Methods: A study was conducted in 50 formalin fixed cadaveric hearts, during a period of two years. In the routine dissection for 1st MBBS and also museum specimens we encountered 3variations in the branches of arch of aorta. Results: The variations in aortic arch branching pattern were observed in 4 cadaveric hearts (8%). Conclusion: The wide spectrum of variation in the human aortic arch and its branches offer valuable information to catheterize in endovascular surgery for diagnostic and surgical procedures in the thorax, head and neck regions. KEY WORDS: Aortic Arch (AA), Left Common Carotid (LCCA), Left Subclavian (LSA), Brachiocephalic Trunk (BCT), left vertebral artery(LVA).
The Image of the Author and the Character in Provincial Satirical Press in the Early 20th Century
Authors: Zhaplova Tatyana , Khmura Elena
Published: March 2021

The article analyzes the structure of the image of the author and the character in satirical magazines published in Orenburg in the early 20th century. The study shows that creation of a literary «mask» and the dialogization of main characters speech are the key methods to reflect the authors position, who is forced to maneuver between the reader and voluntary censorship. Parody, being an integral part of the arsenal of satirical poetics, contributes to effective intervention in the inconsistencies of modern reality, their correction or eradication. However, the external layer of tests, thanks to the malicious, ambivalent irony, preserves a completely noble and emotionally neutral form of appeal to contemporaries discussing everyday problems. It focuses on the hidden mechanisms of modern reality, affecting consciousness, worldview and social position of an individual and the stages of its development. Parodying the speech of representatives of various social classes, the author, using specific vocabulary and stylistics, clearly delineated the boundaries. It was possible to go beyond them only for a representative of a journalistic community that owned a palette of diverse means and techniques. They stylized characteristic noble metaphorization, merchant and bureaucratic symbolization, masking the lack of both spirituality and reason for existence in the description of peasants life, striking by its terrifying reality. The editorial policy of magazines is clearly reflected in the selection of materials for their distribution on the page. After accusatory materials relevant to the political and public life of the city, everyday genre paintings of national disasters and oppression are placed. It strengthens the readers need for change.

Authors: Еgorova Lyudmila
Published: March 2021

The topicality of the research is explained by the fact that media activity of any region has an immediate impact on forming public opinion and moral values, which, in their turn, are also reflected on the mass media agenda. Mass media as creators of information content provide for forming their consumers positive or negativeу attitude to events. The object of the study is the discourse of the regional media in the Crimea since it is correlated with that of the dominant Russian mass media and combines both local and national characteristics. The author focuses on the genre and thematic features of the media texts that enrich the regional worldview with content meaningful for the residents of the area. This content reflects culture-bound concepts and values of the society, and contains a special code, which is determined by local lifestyle and culture. The texts are composed in a way that they make the audience share these values and concepts and become committed to them. Having analyzed genre preferences of the Crimean and municipal press, the author notes that the prevailing ones are texts concerning politics, tourism, culture, economy and ecology. Besides, the Crimean mass media provide a platform for inter-cultural communication, which is particularly important for the multinational region. The author considers a complex inter-disciplinary research of the Crimean media landscape a good perspective of the study, which might help to develop a strategy of positioning the region among the other sub-federal entities, and determine trends and stereotypes in the sphere of social relation of the republic.

Nano Metal-Organic Framework Particles (i.e. MIL-100(Fe), HKUST-1(Cu), Cu-TPA, and MOF-5(Zn)) using a solvothermal process
Authors: Nandiyanto Asep Bayu Dani
Published: March 2021

Metal-organic framework (MOF) is attractive because of its representation as a class of crystalline porous materials with excellent properties, specifically its chemical functionality and high porosity, making it potentially tailored for various desired applications. Although the synthesis of MOFs have been well-documented, most reports are in the bulk and micrometer sizes. The synthesis of MOFs in the smaller size is still inevitable. This work reports the synthesis of nano MOF particles (i.e., MIL-100(Fe), HKUST-1(Cu), Cu-TPA, and MOF-5(Zn)). In the experiment, MOFs were created by interacting ligands and metal ions in the specific solvent in the solvothermal process. Different from other reports, this study used low concentrations of ligands and metal ions, in which this is effective to control ligand-metal ion interaction, reaction, nucleation, and growth of MOF. The successful synthesis was obtained and effective for various MOF particles by changing types of ligands and metal ions. The study also obtained that compatibility and dilution of the ligands and the metal ions in the specific solvent are important parameters. This information will bring new strategies and further developments for the synthesis of MOF materials for wider range of potential applications in separation, catalysis, dye adsorption, and drug carrier uses.
A Mathematical Model of the Cognitive Semantics of the English Preposition ON

Published: March 2021

This study aims to present a mathematical linguistic analysis in establishing the relations between TRs, LMs, potential senses, and actual senses by using the case of the preposition on found in academic texts under the framework of Trajector (TR) and Landmark (LM) configurations. Data were corpora taken from 10 bachelor’s theses written by Indonesian students. To sort the data, Ant Conc 3.4.1.0 was used to parse clauses or sentences based on the TR-LM configurations. Based on the TR-LM configurations, a mathematical model was developed to discover how these variables are quantitatively related to the number of potential senses produced by using a geometric representation of TR and LM. This study indicates that the relation between TRs and LMs, on the one hand, and the sum of potential senses, on the other, follows the integral function of , which means that the total number of potential senses of Ps equals the integral of TR with respect to LM. Meanwhile, the total number of actual senses, ∑As can be obtained by the integral function of , which equals TR.LM + C where C is -Ls representing the constant of the number of lost senses. This mathematical modeling confirms that TR-LM configurations may be used to generate senses which prove the polysemous nature of prepositions.
Application of SEIR Model in COVID-19 and The Effect of Lockdown on Reducing The Number of Active Cases
Authors: Putra Zulfan Adi , Abidin Shahrul Azman Zainal
Published: March 2021

The spread of COVID-19 within a region in South East Asia has been modelled using a compartment model called SEIR (Susceptible, Exposed, Infected, Recovered). Actual number of sick people needing treatments, or the number active case data was used to obtain realistic values of the model parameters such as the reproduction number (R0), incubation, and recovery periods. It is shown that at the beginning of the pandemic where most people were still not aware, the R0 was very high as seen by the steep increase of people got infected and admitted to the hospitals. Few weeks after the lockdown of the region was in place and people were obeying the regulation and observing safe distancing, the R0 values dropped significantly and converged to a steady value of about 3. Using the obtained model parameters, fitted on a daily basis, the maximum number of active cases converged to a certain value of about 2500 cases. It is expected that in the early June 2020 that the number of active cases will drop to a significantly low level.

Published: March 2021

In today’s era of advanced weapons and technology development, many remarkable inventions have shifted the balance of war towards the strategically enhanced military equipped with tactical weapons and armaments. One of these strategic advancements is stealth technology due to which stealth aircraft are high in demand for the military. The question that rises is How to detect a stealth object? This paper proposes a novel anti-stealth technique using void detection, high frequency wave interference and neutrino beam propagation. Void detection method uses a modified satellite-based radar that searches for areas in the aerospace from which the transmitted signals sent to the ground receiving station are blocked or deflected. High frequency wave interference method is used to generate a stellar trajectory of the stealth aircraft at the detected void. Neutrino beam comprises of energy quanta mainly neutrinos, which are able to surpass the absorption or deflection systems in the stealth body of aircraft. This unique phenomenon produces a moving image, which is the precise location of the aircraft in the space. Using these methods, the trajectory of the aircraft is detected which ultimately leads to the detection of the stealth aircraft itself. The newly proposed methods which are theoretically more reliable than the existing methods may not have been tested but the method planning make them practically feasible considering that the technology used is a part of advanced engineering today.
Computational Analysis of Different Turbulence Models in a Vane Pump Simulation
Authors: Molina Daniel Alberto Beleño , Restrepo Rafael Ramírez , Forero Jorge Eliecer Duarte , Toscano Andrés David Rodríguez
Published: March 2021

The study presents a computational analysis of a vane pump using two different turbulence models namely κ-ε and κ-ω. The geometry characteristics of the vane pump were obtained by disassembly and further measurements. The CAD model for the computational domain was developed in SOLIDWORKS®. The CFD modeling was powered by ANSYS®, which allowed the evaluation of different mesh types and turbulence models. A total set of six simulations were performed to obtain comparison schemes for turbulence model evaluation. Specifically, the angular velocity and excentricity were varied within the simulations. Both turbulence models were carefully validated using the manufacturer´s dataset as validation criteria, obtaining a relative error of less than 5%. The κ-ω experienced the best performance when describing the flow variables, excepting the pressure gradient. Specifically, the κ-ω presented an accurate prediction of edge effects, energy losses in the walls, and turbulent viscosity. Notably, the CFD modeling showed that density and velocity variations are not significant. Overall, CFD modeling demonstrated to be a robust tool to gain insight understanding of the flow interactions in vane pump operation.
Decay of Entanglement of Correlated Qubits Through Bosonic Fields
Authors: Türkpençe Deniz
Published: March 2021

Distribution of entangled parties with the longest time possible is of importance to quantum communication. Therefore, analyzing the decay character of entanglement of correlated qubits in the presence of reservoir effects is of significance to the quantum-based technologies. This study covers the analysis of the temporal entanglement decay of two maximally entangled qubits against different reservoir types and system parameters. It is shown how varying the coupling type of the system to the environment affects the lifetime of entanglement. In the presence of quantum interaction between entangled qubits, it is possible to enlarge the entanglement lifetime depending on the initialization of entanglement.  Model parameters used in the numerical calculations and the results are general enough to be applied in any specific quantum-based experimental task.
Медиация: принятие ответственных решений (о теории и практике посредничества в разрешении споров)
Authors: Лаврова Н.М. , Лавров В.В. , Лавров Н.В.
Published: March 2021

Нельзя не признать достижений медиации – накоплен богатый арсенал методов, способствующих разрешению и предотвращению конфликтов в общественных, деловых и семейных отношениях. Отмечая современный этап медиации, авторы изложили те способы, которые были апробированы ими в посреднической деятельности. Обращено внимание на поэтапность выстраивания процедуры медиации и предложен оригинальный способ «картирования» действий медиатора с выделением ожиданий спорных сторон и формулированием согласованного со всеми участниками конфликта запроса на медиацию. Именно одобренный всеми запрос служит «путеводной звездой» в поиске решения, ведущего к согласию. Предлагаемая авторами классификация конфликтов по критериям провокации и направлениям выхода из конфликтной ситуации может служить «навигатором», помогающим сначала определить местоположение в информационной конфликтной среде, а затем обозначить вектор усилий медиатора. Но вместе с тем нельзя не согласиться с тем, что медиация находится в состоянии становления, и перспектива ее развития обусловлена пониманием принципов, определяющих коммуникацию спорных сторон и принятие решений в проблемной ситуации. В такой ситуации представители конфликтующих сторон, испытывая недостаток достоверных сведений, манипулируют доступной информацией. Им приходится преодолевать дезинформацию, провоцирующую ошибочное решение. Разработка новых эффективных медиативных технологий, способствующих успеху переговоров, не может не опираться на достижения теории в изучении природы информации и в исследовании мозговых механизмов, обеспечивающих принятие ответственных жизненно важных решений. Поэтому в книге излагаются нейроинформационные данные, освещающие действие этих механизмов. В приложении содержатся шаблоны соглашений, регламентирующих урегулирование конфликтов. Приводится ряд методик, облегчающих работу медиатора, и тезаурус терминов, характеризующих природу конфликта и медиации. Данная работа предназначена для практикующих медиаторов и всех тех, кто волейневолей занимается конфликтами и построением толерантных отношений.

Influence of the presence of a “shelf” on the outer surface of the submerged nozzle and the electromagnetic effect within its length on the qualitative distribution of metal flows during continuous casting of steel
Authors: Tretyak A. Yu. , Wang Qiang , Wu Chun-Lei , Shifrin E. I.
Published: March 2021

Continuous casting of steel has many ways to control the quality of the billets. The possibilities offered by electromagnetic stirring are far superior to physical eff ects, but combining these two quality control methods can be extremely effective. Research have shown the possibility of a qualitative effect on the flow of the liquid in the mold with implementation of electromagnetic stirring technology and the “skirt” is used in the form of a “shelf” on the nozzle, which is immersed in the mold. In addition, implementation of this shelf increase the possibilities of using direct-flow nozzles with the slope of the inner wall, where in each case it gives advantages, both with an expanding channel, and with a narrowing one. The design of the shelf also does not affect the implementation of electromagnetic stirring in the process of continuous casting, since it is below the level of the mold meniscus and above the level of the effect of the electromagnetic stirrer in the mold. The results of the research show that when using a “shelf” in the middle of the immersion nozzle depth, the casting process is accompanied by the control of most of the flows that are created when the jet enters into the mold and effect of EMS. It also affects the formation of vertex on the meniscus. And the implementation of a “shelf” at the outlet of the submersible nozzle completely changes the nature of the flow of the incoming jet.
Features of structure and properties formation in welded joints made of A500C and B500C strength classes reinforcing steels

Published: March 2021

In the manufacture of welded reinforcing mesh, rolled products of various strength classes are used. High requirements for mechanical properties and structural condition are imposed on welded joints. Connections must provide a set of operational properties. This article presents the results of studies of the structure and mechanical properties of welded joints of reinforced rolled products of strength classes A500C and B500C, performed by spot welding. It is established that the weld (core) of A500C strength class steel is characterized by the presence of a layer of cast metal (hardness 180–190 HV) with slag inclusions. In the heat-affected zone, widmanstett ferrite and bainite — like structures with a hardness of 251–268 HV are observed. The temporary breaking resistance of A500C steel joints is 322–350 MPa. It is shown that the welded joint of steel of strength class B500C does not have a clear division into structural zones. Similar bainite structures in the form of batch formations are observed in the seam and the heat-affected zone. The hardness of the metal of the welded joint is in the range from 205 to 241 HV, and the level of temporary resistance is 510–525 MPa. It is established that the probable cause of premature failure of welded joints of A500C steel is the presence of large slag formations in the metal seam (core). This may be due to insufficient cleaning and preparation of the weld site. Particles of scale and other contaminants fall into the molten metal of the core and "freeze" in it, forming slag inclusions. Cavities filled with slag reduce the cross-section of the seam and as a result significantly weaken it. In addition, slag inclusions are additional stress concentrators and act as a source of destruction when an external load is applied. For the manufacturer of reinforcing nets, it is proposed, as a technological recommendation, to use additional tools for cleaning the welding site in the form of metal brushes or abrasive tools with additional surface degreasing.
Fine module hobs for processing cylindrical involute gears
Authors: Belov D. B. , Boriskin O. I. , Solovyev S. I.
Published: March 2021

Aspects of formation of a hobs cutting part for processing of gear wheels are considered. In the traditional manufacture of hobs for processing the rear surfaces of cutting teeth, the process of radial or oblique relieving is used, which due to its dynamic nature associated with reciprocating motions of a grinding head with a grinding wheel installed thereon, makes it difficult to ensure high accuracy of teeth pitch and profile, as well as main hob parameters. These shortcomings are effectively eliminated by using the process of screw relieving to process the lateral rear surfaces of the hob teeth. Execution of a hob teeth profi le in the form of a gear rack enables to obtain a hob for processing gear wheels. A number of formulas are given, by means of which it is reasonably proved that hobs made using the considered principle of formation of teeth back surfaces can have a high class of accuracy — AA or AAA. Calculations showed that the displacement of the hob teeth at two revolutions of the main worm screw with a probability of 0.9973 does not exceed 0.13 μm, which is signifi cantly higher than the requirements of GOST 10331-81 for hobs with AAA accuracy class (not more than 4 μm for hobs with a pitch over 0.5 to 0.9 mm). The considered method of forming the hob rear surfaces in the form of counter right and left multi-turn screw surfaces (screw relieving) allows to obtain hobs not only for machining involute gears, but also other types of cutters, e.g. for machining threads, ratchet wheels and other parts having a regular profile.
Comprehensive study of the process of cutting screw grooves on the inner surface of a cylindrical steel sleeve with rotary cutting mandrels
Authors: Kuts V. V. , Gridin D. S.
Published: March 2021

The paper presents the results of a comprehensive study of the process of cutting helical internal grooves on the basis of computer simulation in order to establish the influence of technological parameters of cutting on the forming force. Researches of cutting of screw grooves on thinwalled steel sleeves by a cutting mandrel with various cutting speeds have been carried out. The method of processing internal screw grooves on machines with simple kinematics is presented. The dependences of the influence of cutting rates on implementation of the hidden kinematical connection are established. Graphs reflecting the dependence of the cutting rate on the angle of inclination of the cut helical groove are constructed, and a regression equation is obtained describing the dependence of the studied factors on the axial force. Ranges of cutting rates are established, allowing to provide the maximum productivity at various angles of the spiral inclination. The results of processing the experimental data of the study of the influence of tool geometrical parameters on the forming force when cutting helical grooves on the inner surface of the cylindrical shell are shown. Levels of change of factors, variance of experiment results on each of experiments are defined. The regression coefficients are calculated, the regression equation is compiled, the variance of model adequacy is estimated and adequacy of the regression equation is checked, the nature of infl uence of interaction of cutting rate parameters, front angle and the allowable allowance on the forming force is determined. Based on the results of modeling using the Maple program, a regression equation was obtained that reflects dependence of influence of factors on the axial force per tool tooth, dependence of the influence of the studied factors on the change in temperature in a cutting zone, and also constructed a temperature field reflecting the heat distribution in the processing zone on the example of one experiment. The study was performed with the financial support of the Russian Foundation for Basic Research within the research project No. 19-38-90057.

A bed of rock salt in Komsomolsky Mine occurs in sedimentary strata enclosing cage and skip shafts. When water enters rock salt via underground excavations, boreholes and fractures, rock salt can dissolve and wash out, and voids appear in rock mass. Voids at the lining and rock interface should be eliminated so that never re-appear or grow during shaft operation. Materials used to eliminate voids should ensure stable mechanical linkage both with enclosing rocks and lining. Assessment and analysis of geomechanical processes induced by leaching need monitoring of deformations in a shaft. To this effect, one of the simplest and most informative methods is arrangement of an observation station directly in the shaft lining to measure varying distances between check points. The article briefly describes activities aimed to eliminate voids using different composition grouts. From the analysis of monitoring data, the deformation mechanism is described, and the interaction between different deformation stages and grouting steps is determined.

Talnakh and Oktyabrsky ore fields are estimated as rockburst-hazardous starting from the depth of 700 m downward according to safety rules. This means that mining is only permitted within certain protected zones. At the present times, such protected zones are generated in underground mines by means of the large-diameter destressing drilling. Despite proved efficiency, the high cost and large amount of the destressing drilling are the grave faults of this approach. Aiming to save drilling cost, it is proposed to make rock mass rockburst-unhazardous using destress blasting. This article gives a brief description of the destress blasting mechanism. This method has been effectively used in relaxation of pillars from stresses before extraction of the reserves from the pillars both in Russia and abroad. In Oktyabrsky Mine stress relaxation of pillars was implemented by slotting, and the drilling and blasting data were available. This study proposes to destress rock masses by means of directional destress fracturing in horizontal plane through blasting of decked charges of special design. The initial parameters for destress blasting using holes with diameters of 76 and 130 mm are determined. The charge design aimed to ensure a zone of fractures in the horizontal plane, at minimized vertical fracturing is described. This information can be used in planning of full-scale tests to refine parameters and application ranges of the method. For the full-scale tests, it is suggested to undertake destress blasting at different blast patterns on different test sites, and to compare the results with the current destressing method (destressing drilling). Efficiency can be proved using geomechanical and geophysical methods. The authors appreciate participation of V. P. Marysyuk and T. P. Darbinyan from NorNickel’s Polar Division in this study.

The paper presents the investigation results on two technological samples of alluvial garnet sands from Yavr area located in the southwest of the Kola Peninsula. The first sample TP-11/2 (mass 250 kg) was used to study the granulometric, mineralogical and chemical composition of garnet sands. The second sample TP-12 (mass about 6.5 ton) was used to manufacture some garnet concentrates for the waterjet cutting testing. It has been established that the main material of TP-11/2 sample is concentrated in the size of -0.63 + 0.10 mm. The larger particles make 5.0%, the smaller particles make 7.0%. The size distribution in the TP-12 sample is similar. The main minerals of the sands are quartz, feldspar, garnet, amphiboles, pyroxenes, mica, rutile and ilmenite. The percentage of secondary minerals represented by sillimanite, kyanite, apatite, tourmaline, graphite, magnetite, and single zircon grains is less than 2%. Garnet in Javr area sands is 9–-97% in the free phase. The mass concentration of garnet in the sands is 15–19%, the mass concentration of rutile is 1.0%. Garnet corresponds to almandine in composition. A small part of garnets (about 15–20%) contains a pyrope component. The prevailing shape of garnet grains is angular; the profile of the grains is predominantly isometric and elongated. The garnet sands were dressed at the pilot concentration plant of the Mining Institute, in the gravitymagnetic-electric circuit using the following equipment: a fine screen, a spiral sluice, a concentration table, a weak field magnetic separator, a high-intensity magnetic separator, an electrostatic separator for scavenging of rough garnet concentrates. According to the test results, all garnet concentrates with the size of –0.63 + 0.315 mm, –0.315 + 0.18 mm, –0.18 + 0.10 mm were assumed suitable for the waterjet cutting.
Extraction of vanadium and associated elements from black shale ores by hydrodynamic activation technology of sulfuric acid solutions
Authors: Mamytbekov G. K.
Published: March 2021

The purpose of the work was to justify the possibility of converting vanadium in ore mainly into a readily soluble form in the form of hydrated oxides — vanadyls of the general formula VO2+ X (X is an anion) due to the hydrodynamic activation of sulfuric acid solution. Leaching tests were carried out in several stages and by various methods, the duration of which depended on the final indicators of vanadium extraction into the productive solution and its residual content in ore, as well as side components (Mo, W, rare earth metals). The article for the first time is examined the extraction of vanadium and associated elements from black shale ores (Kurumsak deposits, Kyzylorda oblast, the Republic of Kazakhstan) by the hydrodynamic activation of sulfuric acid. The activation of sulfuric acid solutions is carried out in the cavitation mode in a circulating type hydrodynamic apparatus at a pressure of 5 atm supplying a fluid flow to the cavitation nozzle by means of a centrifugal pump. It was found that the hydrodynamic activation of sulfuric acid leads to a significant increase in the degree of extraction of vanadium from 6 to 87% and related components depending on the decreasing in granule size. The technological parameters of leaching, such as pH, redox potential, salinity, acid intensity and filtration, are significantly improved. The results of chemical analysis of productive leaching solutions of the ore for the total contents of V2O5, uranium and rare earth concentrates were equal to 0.62 and 0.95 g/l, 47.26 and 41.43 mg/l and 62.44 and 37.26 mg/l irrespectively, that indicate the technological possibility of carrying out the heap leaching process.

This article discusses the task of developing an urban planning methodology for assessing the degree of destruction of residential areas aff ected by hostilities in Syrian cities. This methodology will be the basis for the theoretical substantiation of the process of restoration the destroyed residential areas of the cities and their functional planning organization in the context of ongoing military confl icts. The research is based on the methodology for assessing the degree of destruction of buildings presented in GOST R 42.2.01-20141 « Civil defense. Assessment of the state of potentially dangerous facilities, defense and security facilities under the infl uence of damaging factors of conventional weapons» .The state of the buildings destruction is determined using satellite imagery as well as fi eld tests. The parameters of the damaging factors are determined analytically. The developed methodology makes it possible to determine the degree of destruction of residential areas within the radius of destruction formed by the excess pressure of the blast wave and the explosives used and to assess the suitability for recovery in the context of continued hostilities. On the basis of the established degree of destruction of residential areas, a scheme of urban planning zoning of the residential area of Homs was made.
