A Contextual and Canonical Reading of Psalm 35
Authors: Simango Daniel
Published: February 2023

This article is a contextual and Canonical reading of Ps 35 in order to grasp its content, context and theological implications. The basic hypothesis of this study is that Ps 35 should not be interpreted in isolation, but that the psalm will be best understood when read in its total context viz., the historical setting, life-setting and canonical setting as well as the literary genre. It is argued that a contextual and canonical reading of Ps 35 can serve as a counterbalance to arbitrary decisions on the interpretation of the psalm. A brief overview of the structure and outline of this psalm is given before probing the literary genre, historical setting, life setting as well as the canonical context. The article concludes by discussing the imprecatory implications and message of Ps 35 to the followers of YHWH.
A Pentecostal Reception History of the Book of Judges
Authors: Martin Lee Roy
Published: February 2023

This early Pentecostal reception history aims to locate the book of Judges within the Pentecostal context and to discover the effects of the book on the tradition's theology and practice. The study examines North American periodicals (plus Confidence, a British publication) from the beginning of 1906 (the start of the Azusa St. revival) to the end of 1925, a period that historian Walter J. Hollenweger describes as the "heart" of the Pentecostal movement. These early voices help to shape a Pentecostal approach to the book of Judges as they show how this segment of the first generation of Pentecostals struggled with issues such as paradigms of leadership, the necessity of Spirit empowerment, the role of women in ministry and the relationship between purity and power. The testimonies, sermons and articles reviewed here demonstrate that some early Pentecostals identified with the stories and characters in Judges and appropriated them to the Pentecostal context.
Stochastic analysis of dig limit optimization using simulated annealing
Authors: van Duijvenbode J.R. , Shishvan M.S.
Published: February 2023

The results of dig limit delineation in open pit mining are never truly optimized due to gaps in the underlying data, such as insufficient sampling. Aside from the data uncertainty, there is also an influence on the final dig limit by either humans or by the heuristic character of an optimization method like simulated annealing. Several dig limit optimizers have been published, which can replace the manual dig-limits designing process. However, these dig limit designs are generally not adapted to account for this heuristic character. In this paper we present a stochastic analysis tool that can be used with the results of heuristic dig-limit optimization to increase confidence in the obtained results. First, an enhanced simulated annealing algorithm for dig limit optimization is presented. Then, this algorithm is tested on ten different blasts at the Marigold mine, Nevada, USA, as a case study. Finally, the results are analysed with a destination-based ensemble probability map and an analysis conducted of the final solution data distribution. The generated dig-limit designs of the algorithm include high revenue areas that are excluded in comparable manual designs and show improved objective and revenue values. The analysis tool provides block destination probabilities and box plots with the distribution of opportunity value for the dig limit. Furthermore, with the analysis tool, it is possible to make well-informed design decisions in areas of uncertainty.
Simulation of production processes and associated costs in mining using the Monte Carlo method
Authors: Mathey M.
Published: February 2023

The application of the Monte Carlo technique to production planning and everyday economic decisionmaking in mine production management is demonstrated. The logic is detailed using an example of underground production with continuous miners (CMs) and truck haulage. It is argued that availability of equipment and personnel are the predominant variables influencing mine output and productivity and that those availabilities may be well represented by binomial probability distributions. The probabilistic model is implemented in a standard Excel® spreadsheet with Palisade's @Risk add-on to facilitate simulations. Starting from model calibration against data obtained from a mine's annual reports, some general interdependencies of availability, utilization, productivity, and costs of production processes are outlined. Finally, several possible options and their consequences as regards production improvements are explored.

An extended fluid model is formulated that describes a corona microdischarge at atmospheric pressure in argon, taking into account the heating of the cathode-tip. Numerical calculations have been carried out, demonstrating two main modes of the negative corona: repetitively pulsed and glow discharge mode. For both modes, all the main parameters of the corona discharge plasma were obtained. It is shown that the appearance of Trichel pulses is in many respects similar to the transition from the Townsend to the glow discharge mode and is similar to self-oscillations manifested in a classical discharge with flat electrodes.

The nature of phase transitions. (The role of self-consistent feedback in the evolution of material structures)
Authors: Godizov A.G.
Published: February 2023

The inability of statistical mechanics to determine the bounds of the condensed media phase regions, to compute the thermodynamic coordinates of phase transitions, to predict the molecular structures astride of the phase transition points, to estimate the rates of transitions from nonequilibrium to equilibrium, to determine the dependence of the solid body structure on the rate of the liquid melt cooling, etc. , is one of the most chronic diseases of modern theory. All these defects are related to the fundamental problem of unification of the laws acting in microcosm and in macrocosm. It is indisputable that these laws describe the same, i.e. , material systems of many interacting particles. Therefore, a general law must exist which connects both the levels of description of matter into a comprehensive whole. Mechanics itself does not contain the collective properties of many-particle systems, but, following the general logic, the signature of these properties should take place in the laws which govern the microscopic behavior of the system elements. The feedback principle pretends to accomplish such unification without any violation of the principles which underlie statistical mechanics.

The paper presents the results of studies of thermal conductivity, structure and physico-chemical properties of samples of polymer composite material based on thermosetting phenol-formaldehyde resin and hexagonal boron nitride. It was found that with an increase in the volume fraction of boron nitride from 5 to 85%, the effective thermal conductivity coefficient at 300 K increased from 0.63 to 18.5 W/m·K. The experimental results are compared with the data calculated using known theoretical models used to describe the process of thermal conductivity in polymer composite materials.

Authors:   Baku State University, Bayramova G.A.
Published: February 2023

In this study, the bound state's solution of the modified Schrödinger equation is found for the new supposed combined Hultén potential and the Yukawa class potentials. Analytical expressions for the energy eigenvalue and the corresponding radial wave functions are obtained for any orbital quantum number. Obtained eigenfunctions are expressed in terms of hypergeometric functions. To overcome the potential's centrifugal part difficulties, we applied the developed approximation scheme for studying bound states. It is shown that energy levels and eigenfunctions are susceptible, depending on potential parameters. Finally, we investigate also the eigenvalue of the energy and the corresponding radial wave function under some exceptional cases.

A binary coding method is presented for studying the processes taking place in closed areas formed by cluster structures. The stochasticity of the processes inside the clusters of the ice-water system during the phase transition does not allow obtaining accurate values of the specific heat of melting of ice-containing mixtures. At the moment, there are no methods to verify the scatter of the results of studies of the enthalpy of melting of ice-containing mixtures. Converting the data arrays obtained in the course of a series of experiments into a binary format makes it possible to analyze the change in the values of the enthalpies of melting by comparing the finite numbers of each series. The resulting list of numbers clearly shows the presence or absence of matches in the required data arrays. To implement this method, a program has been developed in the Python programming language, which is a cross-platform application with an intuitive interface.
Investigation of the structural heterogeneity of the aluminum melt by the method of acoustic emission
Authors:   Ural State Railway University of Railway Transport, Vorontsov V.B. , Pershin V.K. ,   Ural State Railway University of Railway Transport
Published: February 2023

Acoustic emission (AE) is experimentally investigated when the temperature of the aluminum melt changes. The Fourier analysis is carried out of the amplitude-frequency spectrum of AE signals in the temperature range of 665-860 ° C In the studied frequency range, periodic repetition of signals with maximum intensity was established. It is assumed that the acoustic spectrum of the signals is associated with structural rearrangements in the melt and reflects the transformation of the local order in liquid aluminum. Dynamics of changes in the intensity of AE signals with an increase in the melt temperature suggests that the local order in the melt inherits the structure of the crystalline precursor. The paper analyzes the process of cluster formation during melt cooling. Based on the above, the concepts of the melt structure as a partially ordered cluster environment are discussed.

Authors:   Baku State University, Abdulvahabova S.G. , Afandiyeva I.G. ,   Azerbaijan State University of Oil and Industry
Published: February 2023

In this paper, we propose a Regge-pole model with a Gaussian potential for studying hadron scattering at high energies. In the diffraction approximation and the consequences arising from the analyticity and unitarity of the scattering amplitude, an expression is obtained for the matrix of the scattering amplitude, for the cross section, and for the slope parameter of the diffraction cone for the reactions a+A® B+b . The resulting expressions are applied to p-p scattering. The results show that the model describes well the slope coefficient of the diffraction cone at energies below 102 GeV. For agreement with experiment at high energies, it is necessary to tune the parameters.

About determination of the hubble constant from cosmic microwave background in the presence of angular momentum in photons
Authors:   Moscow Automobile and Road Construction State Technical University, Portnov Y.A.
Published: February 2023

At the moment, it has become obvious that there is a significant contradiction between the methods of measuring the current rate of expansion of the Universe from the cosmic microwave background (CMB) and using local distance sensors. This fact prompted some researchers to interpret this contradiction as evidence of new physics. In this article, without resorting to new physics, the probable source of this discrepancy is determined as the unaccounted angular momentum of the photons of the microwave background. It is shown that taking into account the angular momentum of the CMB photons helps to bring into agreement the values of the expansion rate of the Universe, measured by different methods.

The oxidation of carbon monoxide on the surface of the Au/Al2O3/Mo(110) structure was studied using modern methods of surface diagnostics. With a high degree of identity of the structural, electronic, and adsorption properties of the Au/Al2O3/Mo(110) system with different aluminum oxide film thicknesses (2, 4, 6, 8 monolayers), it is shown that the oxidation efficiency of CO molecules desorbed into the gas phase decreases exponentially with increasing oxide film thickness. Taking into account the well-known fact that the efficiency of CO oxidation depends on the amount of excess charge acquired by the gold nanoparticle, it is concluded that tunneling the charge through the oxide layer increases the efficiency of the reaction on the surface of the studied metal oxide system.

Investigates the effect of the increase in relative humidity on the change in the number concentration of fine particles suspended in the air in a closed sealed volume. This work was carried out within the scope of a series of works of the SIRIUS international project. The project is aimed at studying the dynamics of aerosol accumulation in the air environment of a sealed inhabited object using methods for assessing the level of aerosol contamination used in cleanroom technology. A qualitative result of the relationship between the number concentration of the airborne particles and the relative humidity inside the sealed volume in the absence of other sources of particle generation was obtained. This result correlates with the experimental data obtained during the SIRIUS four-month isolation experiment and lays the foundation for preparing for new isolation experiments of the SIRIUS project.

The emissivity of a LED heterostructure with quantum wells of a combined profile obtained by composing several rectangular wells of different thicknesses and heights is considered. The lower well of the smallest thickness is emitting, and the other wells located above it increase the rate of capture of charge carriers from the barrier layers. The performed consideration of the energy spectrum in the wells and the calculation of the radiation intensity of combining a well composed of three wells show the possibility of a significant increase in the radiation intensity of a heterostructure with wells of a combined profile.

In this paper we have successfully formed fixed joints by butt friction stir welding of rolled sheets made of Ti-6Al-4V titanium alloy, using tool made of a heat-resistant alloy based on nickel ZhS6U with liquid cooling in the welding process. There was found a formation of a part of the welding tool material in the stirring zone of the fixed connection by methods of metallographic analysis. It was shown by fractography methods that the fracture in the joint zone was ductile, however, when the tool material was caught, the fracture was brittle. In spite of this, by modifying the welding parameters, it became possible to obtain a connection equal to the strength of the base metal.

Published: February 2023

We propose a double cascade scheme for reducing the concentration of232, 234, 236U isotopes in regenerated uranium hexafluoride. In the product of the first ordinary cascade the greatest decrease in the236U /235U mass ratio with enrichment in235U to a concentration of less than 20% is provided. To ensure the required concentrations, a special mode of operation of the stages. In the second ordinary cascade, which is fed by the product of the first, enrichment in isotopes232,234U is performed. The waste flow, purified from232, 234U, is diluted to a concentration of235U less than 5%. A method for calculating the parameters of cascades with stage separation factors corresponding to gas centrifuges is presented. A computational experiment was carried out on its basis. It was shown that the product obtained after dilution with respect to isotopes232, 234U meets the requirements of the ASTM C996-20 specification for the low-enriched commercial grade of uranium hexafluoride. The content of236U in it is several times lower than in the case of direct enrichment of regenerated uranium hexafluoride.

The paper provides a brief review of studies of the bulk viscosity of liquids and liquid dispersed systems. Obtaining experimental data on the viscosity of liquid dispersed (colloidal) systems is complicated by a number of factors: the difficulty of creating monodisperse systems, various methodological problems of accurately measuring the size of particles, their concentration, degree of homogeneity, and distribution. And also the difficulty lies in the fact that with an increase in the concentration of particles, a liquid dispersed system from a Newtonian liquid becomes non-Newtonian. The absorption of acoustic waves in a liquid is associated with both shear and bulk viscosity. It is shown that in most cases the value of bulk viscosity is much higher than the value of shear viscosity, and their ratio changes with increasing temperature. The data obtained on the basis of the Stokes model of absorption of sound waves are considered.

Based on a brief analysis of scientific data on streamer discharges, it is proposed to classify streamer discharges into free and guided ones. Guided streamers (linear and branched) have been obtained in air at pressures from 30 to 150 Torr. The speed and structure of the glow of ionization waves at the start, during deceleration and at the branch point are determined by the method of high-speed shooting. It was found that the glow of a ionization wave consists of two parts - the main wave and its precursor. The emission of the precursor wave is much less intense than that of the main wave, and contains predominantly the 2+ band of N2, as well as the 1- band of N2+. This, and also the fact that the experiments were carried out at low air pressures, explains why this glow was not observed earlier. They can subsequently be used to build test theoretical models of the phenomenon.

The paper studies the structure and phase composition of Ti-Ni alloy of near-equiatomic composition after its mechanochemical alloying with titanium in a planetary ball mill and subsequent heat treatment and hydrogen sorption during hydrogenation. The content of titanium in powder mixtures varied from 7 to 25 wt.%. It is shown that the phase composition of the Ti-Ni powder before mechanochemical alloying consisted of TiNi ( B 2, B 19'), Ti2Ni and Ni3Ti phases. The (Ti-Ni) - Ti powders consisted of TiNi ( B 2, B 19') and Ti2Ni phases after mechanochemical alloying and subsequent heat treatment. It was revealed that the Ti2Ni phase had a different genesis. The Ti2Ni (I) phase existed in the Ti-Ni powder before mechanochemical alloying, the lattice parameter the Ti2Ni (I) did not change and was equal to 1.1283± 5∙10-4 nm. Phase Ti2Ni (II) is formed in the process of mechanochemical alloying and subsequent heat treatment, the lattice parameter of Ti2Ni (II) decreased with increasing titanium content added into the Ti-Ni powder during alloying. It was revealed that the composition Ti-Ni (85 wt.%) - Ti (15 wt.%) has the maximum content of the Ti2Ni phase. It is shown that the average particle size increased with an increasing of titanium content added into the Ti-Ni powder during alloying and subsequent heat treatment due to the process of particle consolidation. Hydrogenation of a Ti-Ni (85 wt.%) - Ti (15wt.%) powder during 90 min leads to a change in the Ti2Ni (II) lattice parameter, which corresponds to the Ti2NiH1.9 hydride parameter, and during 360 min, to Ti2NiH2.8.

Published: February 2023

The influence of severe plastic deformation and subsequent pre-recrystallization annealings on the structural-phase state and mechanical properties of the VT35 titanium alloy has been studied. It is shown that the formation of an ultrafine-grained structure leads to an increase in the mechanical properties of this alloy at room temperature by 65-75% compared to the initial coarse-grained state. It has been established that a significant scatter in the mechanical properties of the alloy after such treatment is due to the inhomogeneity of the distribution of α and β phases in the bulk of the workpieces. Subsequent pre-recrystallization annealings of the VT35 ultrafine-grained alloy at temperatures of 723 and 773 K lead to an additional increase in its mechanical properties (the yield strength and ultimate strength values can exceed 1700 MPa). Using the example of alloy samples after annealing at 723 K for 0.5 h, it is shown that the increase in mechanical properties is due to an increase in the volume fraction of the α-phase due to the β→α phase transformation occurring inside the β phase regions and, as a result, a more uniform distribution of α and β phases.

TiO2-Ag nanoparticles with thermal and chemical stability, wide band gap and low toxic are more used photocatalysts for decomposition of organic substances. However, high rate of recombination of electron-hole pairs and high energy of photoactivation significantly limit their usage. Modification of TiO2 with silver promotes surface separation of charges and increases their photochemical activity. In the present study for obtain TiO2-Ag bicomponent nanoparticles was use electric explosion of metal wires in atmosphere 85 vol.% Ar - 15 vol.% O2. This method has a high productivity (170-200 g/h) which is enough for industrial application of nanoparticles. However, electroexplosive nanoparticles are mostly agglomerates with a size of 200-500 nm, which significantly reduces their photochemical activity in the test reaction of decomposition of the model dye methylene blue under the visible light radiation. Ultrasonic treatment of nanoparticles in aqueous suspension for 15 min. contributed to an increase in the photoactivity of TiO2-Ag nanoparticles by 10%

Published: February 2023

The calculation of the Franck-Condon factors previously absent in the literature for forbidden transitions associated with the first negative and second positive systems is carried out on the basis of the Morse potential. For allowed transitions, it is shown that the Morse potential makes it possible to accurately calculate the values of the factors depending on the value of the vibrational constants. With an increase in the vibrational number, there is a deviation from the values of the factors determined on the basis of a more accurate Rydberg-Klein-Ries potential

The effects of interaction of spinning particles having intrinsic angular momentum (spin) and describing by the Dirac equation with a vortex gravitational field are considered. It is shown that the interaction of massive Dirac particles with a vortex gravitational field leads to a precession of their spin around the axis of rotation of the vortex gravitational field. In the case of massless particles, their spin is set along the axis of rotation and remains constant, thus the spin of Dirac massless particles indicates the direction of the rotation axis of the vortex gravitational field.

The article presents the results of the study of specific variants of interference in the Slavic-Turkic language contact, namely the deviations from the norms of gender and number expression in the Russian speech of Turkic-Russian bilinguals, with fundamentally different ratio in the grammatical systems of the contacting languages. The Slavic and Turkic languages are typologically different (inflectional synthetic VS agglutinative) in their grammatical categories, types of intercategorical interaction, configurations of particular grammatical meanings and their formal markers within the same categories. The Slavic and Turkic languages are in close intense contact, which results in multiple variants of interference in the speech of the bilingual speakers. The authors have analysed the speech (about 140,000 words) of 22 respondents, aged from 23 to 81, with their education level ranging from primary to higher, to conclude that the differences in the grammatical structures of the interacting languages influence the number of grammatical errors in L2: 1) errors in the use of the grammatical gender prevail in all syntactic positions, due to its absence in the native Turkic languages of the bilinguals; 2) differences in the structure of grammatical number in the contacting languages resulted in the prevailing deviations from the speech standard in the use of number forms of material and collective nouns; 3) the variability of the particular grammatical meanings of the masculine, feminine and neuter genders in Russian resulted in the fact that the masculine gender, which is the unmarked member of the gender opposition, proved to prevail in all syntactic positions, except the coordination relation of the linking verb in compound predicates; 4) interference phenomena interact with current trends in the development of the Russian language, as well as with the spontaneous character of oral speech.
The Galician Operation of 1914 and its Influence on the Development of the Neo-Russian Style: A Case Study of Archeology and Iconography of the Fedorov Town

The conquest of Galicia, thought as a necessary stage to take the Rusins of the Austro-Hungarian Empire into Russian citizenship, influenced the archaeological and iconographic program of the Fedorov town and the Ratnaya Palata (Martial Chamber), the largest pre-revolutionary neo-Russian monuments. The article proves that the Galician operation and the Battle of Łódź had symbolic significance for the renewal of the Martial Chamber exposition, with the former standing for fearlessness in the face of both military and civil dangers. It meant the need to equip the Slavic world not only on the imperial principles of subordination of different peoples to the emperor, but also on the national pre-Peterian ones, when the Slavs, including the Rusins, had a common language and a understanding of symbols. The Battle of Łódź meant a miracle to which even enemies submit. Both ideas, “peace” and “miracle”, turned out to be key in the development of a complex iconographic program of paintings and interior of the Fedorov town, so that its real meaning became clear only after the Emperor had visited the construction site and talked to the artists. The analysis of the original documents on this visit, including the recordings of the tsar’s dialogues, as well as the insightful contemporary reflections by the poet Stratanovsky, demonstrates that the Fedorov town represents a complex dialectical synthesis of imperial and national styles, different from the national romanticism, which makes the reduction of the Fedorov town to national romanticism untenable. On the contrary, the images and symbols from the architecture and books related to the first Romanovs were updated by the First World War. The new program of Slavic unification differed from the periovious projects and required a special approach to the unification. Quoting the contexts of religiosity of Russian symbolism and the influence of artistic impressionism clarifies this program and specifies how Nicholas II thought the future of the Russian people, including Rusins, shortly before the political catastrophe of February 1917.

Published: February 2023

The article analyzes the principles of creating a socio-cultural image of RusinsRusnaks in the novel Wandering People (2012) by Ukrainian writer and journalist O. Havrosh through the prism of the writer’s artistic consciousness. The author studies the writer’s mentative about the Rusin community, compactly living in Serbia, and the writer’s emphasis on the uniqueness of the descendants of Carpathian immigrants, who managed to preserve and create a special ethnic group in new conditions. Outlining O. Havrosh’s descriptive discourse in the in the travelogue, which consists of separate essays, the author analyses the specificity of the artistic and documentary description of the life of the contemporary 15,000 Rusin community in Serbia. The article focuses on the writer’s artistic practices related to the reproduction of mentality, depiction of life, traditions, customs, beliefs, history, culture, and religion of Rusins-Rusnaks, who settled in Serbia more than 270 years ago and preserved their identity to our time. Having analysed the factors and circumstances of Rusin self-identification, the author emphasizes their uniqueness: being peaceful by nature and showing tolerant attitude to other cultures and religions, they have not assimilated with other European peoples for a number of reasons. The articles tells about the characters of the novel and their specific actions and deeds aimed at preserving and increasing Rusin traditions and customs. The analysis allows speaking about artistically interpolated processes of national and personal self-identification as of a socio-cultural phenomenon.
Historical language personality of the 18th century through the prism of xenolexis (based on A.V. Suvorov’s letters)

The article focuses on the linguistic personality of A.V. Suvorov – one of the most important historical figures famous for his military achievements, including his service and warfare in Slavic territories (military service in the Lublin region, participation in hostilities in Poland, the Battle of Brest, etc.), a prominent representative of the Russian cultural elite in the 18th century. The study employs methods of linguopersonology and historical lexicology. It aims to describe a historical language personality, viewed as a reflection of both an individual with a linguistic potential, a type of specific linguistic reflection, and of the era as a whole with its inherent linguistic features and tendencies. Processes in the language at a given time period are also manifested in the language of an individual. The study focuses on the borrowed lexis, reflecting the general instability of the Russian language system of the period, which resulted from the prevailing multilingualism of the Russian nation, a significant increase in foreign words in the Russian language, and a change in linguistic norms. Through the prism of xenolexis, the authors describe Suvorov’s language personality reflected in his letters to note his broad outlook, fluency in native and foreign languages, linguistic intuition, innovative use of units of native and foreign languages.
Slavic languages in the face of challenges: semantic and derivational history of vyzov and wyzwanie (based on Russian and Polish languages)
Authors:   Irkutsk State University, Tashlykova M.B. , Starodvorskaia E.V. ,   Irkutsk State University; Adam Mickiewicz University in Poznań

The article deals with the semantic history of the group of lexical units in closely related languages (Rus. vyzvat’, vyzov, Pol. wyzwać, wyzwanie, wezwać, wezwanie). Despite etymological relationship between these words, they distribute and embody the same meanings differently. Among other things, this concerns the representation of the sense that has been described as a result of semantic calquing of the Eng. challenge. It is shown that the latest tendency of the use of vyzov is not entirely new and continues, in a logical and consistent way, semantic history of the word. A fertile ground for its new sense has been provided by the “competitive” meaning of vyzvat’, which requires the semantic role of “counterpart” within argument structure of the verb. That said, however, the new meaning of vyzov is generally found in contexts related to global forces that threaten the stability of the world. The pieces of conceptual structure that are embodied by Russian vyzvat’ and vyzov are distributed between two Polish verbs (wezwać and wyzwać) and the noun wyzwanie. The meaning in question (that one loaned from English), despite its novelty, seems to be conveyed by Polish deverbal noun more accurately than by its Russian equivalent. This is evidenced by its use in more diverse contexts including speaking of everyday activities. All things considered, it appears that in this case the Polish semantic system offers the perfect example of semantic calquing and that the explication of the calqued meaning in Russian requires more caution.

A törpe mandula (Prunus tenella) tömeges előfordulása szántásból felhagyott kunhalmon

A kunhalmok ex lege védett természeti területekként jelentős biodiverzitás őrzői, mivel még az intenzíven használt mezőgazdasági tájakban is számos löszgyepi növényfaj előfordulása kötődik ezekhez a kis élőhelyszigetekhez. Természeti és kulturális jelentőségük ellenére az elmúlt évszázadokban számos halmot beszántottak. A közelmúltban azonban a halmok bekerültek az  agrártámogatások rendszerébe, így az Alföld számos régiójában elindult a kurgánok szántóföldi művelésének felhagyása. Országos felmérésünkben a szántásból felhagyott halmok növényzetének regenerációját vizsgáljuk, jelen közleményben e felmérő munka során tapasztalt egyik érdekes botanikai jelenségről számolunk be. A tiszainokai Fekete-halmon – melyet egészen 2014-ig intenzív szántóként használtak – a  törpe mandula (Prunus tenella Batsch; syn.: Amygdalus nana L.) közel 15.000 hajtásból álló állományát találtuk hat évvel a szántóföldi művelés felhagyása után. Az állomány valószínűleg a halom tetején a háromszögelési pont védelmében tudott fennmaradni, ahonnan a felhagyást követően hatékonyan ki tudott terjedni. Ez a megfigyelés egy érdekes adattal gazdagítja a Tiszántúl flórájának ismeretét, valamint rámutat arra is, hogy a szántóföldi művelésből felhagyott halmok természetvédelmi szempontból értékes fajoknak is élőhelyet nyújthatnak, valamint hogy a természetes úton történő, spontán visszagyepesedés is hatékony természetvédelmi módszer lehet egyes halmok esetében.
