Stationary and pulsed electrodeposition of silicon in LiCl–KCl–CsCl–K2SiF6 melt
Authors: Parasotchenko Yu. A. , Suzdaltsev A. V. , Zaikov Yu. P.
Published: October 2024

Silicon and its materials are widely used in metallurgy, micro- and nano-electronics, solar energy, and are also promising materials for anodes of lithium-ion power sources with increased specific capacity. The expansion of application areas of silicon with controlled morphology necessitates the development of new energy–efficient methods of its production. In the present work, the influence of the mode as well as parameters of electrolysis of the LiCl–KCl–CsCl–K2SiF6 melt with a temperature of 545 оC on the morphology of electrolytic precipitation of silicon on glassy carbon has been studied. The galvanostatic mode of electrodeposition, widely used in industry, as well as the pulsed mode, which is actively investigated at present, were used for the electrolysis. Silicon electrodeposition was carried out by varying such parameters as cathodic current density (from 3 to 50 mA/cm2) and electrolysis duration (from 30 to 180 min) in the galvanostatic mode, as well as by varying the density and duration of the cathodic current pulse, the duration of current pauses and the total duration of electrolysis in the pulsed mode. It is shown that electrodeposition of silicon on glassy carbon is accompanied by the formation of a continuous sediments of hemispherical nuclei with a diameter of about 1 micron on the electrode surface. An increase in the cathodic current density and an increase in the cathodic current pulse pause frequency contribute to the disruption of the sediment continuity and the growth of dendrites of ordered or arbitrary shape. At the same time, the pulsed mode allows to increase the cathode current density at silicon electrodeposition (from 25–30 to 250–500 mA/cm2) and stabilize the value of the cathode potential during electrolysis.

Published: October 2024

To assess the possibility of joint processing of ilmenite (FeTiO3) and perovskite (CaTiO3) concentrates using a duplex process involving solid-phase reduction of iron (metallization) and subsequent separating melting into pig iron and titanium slag, the properties of slag melts were studied. The crystallization beginning point (liquidus temperature) and the corresponding viscosity of titanium slag depend on its chemical composition. The increase in titanium oxides content results in increase of these properties, while the presence of iron and calcium oxides leads to their decrease. During the joint processing of ilmenite (IC) and perovskite (PC) concentrates, the CaO content in the slag can be adjusted by changing their PC/IC ratio, and the FeO fraction is determined by the degree of iron metallization during the preliminary reduction roasting of a concentrate mixture with a carbon reducing agent. To select the optimal PC/IC ratio the temperature dependences of the viscosity of model oxide melts of the TiO2–FeO–CaO–Al2O3–MgO system, similar in composition to the slags formed as a result of melting mixtures of perovskite and ilmenite concentrates within the range of PC/IC ratios equaling to 0.6÷1.4, and the metallization degree from 75 to 95% were determined.
According to the results obtained, within the entire range of studied compositions and temperatures, the viscosity of slag melts does not exceed 0.8 Pa·s. That is to say, such slags will be sufficiently fluid at the tapping point if the melt temperature is higher than liquidus temperature — the crystallization beginning point. Increasing the PC/IC ratios when decreasing the metallization from 95 to 75%, results in a monotonous decrease in liquidus temperature and its corresponding viscosity from 1490 оC and 0.79 Pa·s up to 1270 оC and 0.17 Pa·s, respectively. It is recommended to use a charge containing equal mass fractions of concentrates (PC/IC equal to 1) at the consumption of carbon reducing agent based on metallization of 85% iron. In this case, slags with a relatively low iron oxide content (3.1%) will be fluid (0.38 Pa·s), and have liquidus temperature of 1400 оC which will allow carrying out top and bottom melt at operating temperatures of 1500–1550 оC.
Simulation of dissolution of cerium trifluoride in a mixture of LIF–NaF–KF
Authors: Zakiryanov D. O.
Published: October 2024

The study of phase diagrams of multicomponent molten mixtures is traditionally carried out either by experimental measurements or thermodynamic calculations based on known experimental data. Atomistic modeling occupies a significantly smaller share in the methodology, and the capabilities of this approach have been poorly studied. In this work, we simulated the dissolution of cerium trifluoride in the ternary eutectic of lithium, sodium, and potassium fluorides using the molecular dynamics method. A time- and ensemble-scale simulation of the coexisting crystalline phase and melt at several temperatures was carried out. The influence of ensemble size was studied. The rate of dissolution was studied depending on temperature. The asymptote of the dependence agrees well with the experimental liquidus temperature for a given composition. A conclusion is given about the possibility of using molecular dynamics to determine the complete solubility of a melt component.

The article discusses important issues regarding the creation of a system of economic security of the enterprise, as there is no clear position regarding its necessity. A model of the formation of an effective system of comprehensive provision of economic security of the enterprise based on the implementation of specific actions that determine its mission and goals is presented. It is necessary to ensure the implementation of the specified algorithm of actions and take preventive measures to achieve economic security, and to build in accordance with the implemented policy and the formation of a strategy for its economic security. In this case, the strategy is considered as a long-term approach to achieve the company's goals. In order to counter threats to the economic security of the enterprise and ensure its stable functioning, it is necessary not only to create a comprehensive protection system, but also to ensure its rational functioning for the future.
Depending on the state of the enterprise and the influence of external and internal factors on it, a set of measures is proposed to strengthen the economic security of the enterprise in terms of a separate functional component. It was found that all directions for each separate functional component of the enterprise's economic security provide an opportunity to strengthen the enterprise's economic security as a whole. The result of ensuring the economic security of the enterprise should be the stability of the functioning of the enterprise, the dynamism of its development, the efficiency of financial and economic activity and the personal safety of employees working at this enterprise.
The use of a scientific and methodical approach when building an effective system of comprehensive provision of economic security of the enterprise makes it possible to take into account all possible threats, while all the means of protection used, the developed measures must be interconnected. The creation of such a system allows you to play a key role in ensuring sustainable functioning and the most effective development of the enterprise on the basis of a developed and implemented set of measures.

The article substantiates the importance of modeling management decisions in entrepreneurship, which involves improving business processes and their effectiveness. The use of business models is proposed to be considered as a tool for forming a system of strategic management response to challenges and threats to entrepreneurial activity. It was also emphasized that the essence of the enterprise's business model should be considered through its functions. A number of priority directions for the development of entrepreneurial activity are highlighted, which are important to take into account in strategic modeling and management of business processes. A schematically modified technology of business modeling of strategic management decisions in entrepreneurship is presented, and its elements include the future priorities of consumers, existing and potential strategic resources, key competencies, the system of business processes and the business portfolio of the enterprise. The appearance of the idea of business modeling is connected with the change of the current and the emergence of new opportunities of enterprises in the market environment, and therefore with the complication of the management process. The business model should be based not only on the use of external opportunities and strengths as the basis of competitive advantages, but on the determination and development of the internal potential of the enterprise and the desire to change the parameters of the external environment in such a way that the internal potential receives maximum expression and realization. According to this, the technology of forming the business model of the enterprise is presented. In order to expand the theoretical and methodological basis for the development and implementation of strategic management solutions, the technology of forming the business model of the enterprise is schematically presented. Emphasis is placed on the importance of stable and sufficient resource provision for entrepreneurship in achieving strategic goals.

The subject of this study is an attempt to present the essence of crimes against the environment, from the point of view of the provided criminal sanctions and their comparison with the repressive measures existing in Polish criminal law, against the background of the latest changes in this area, introduced by the Act amending certain acts to counteract environmental crime. The role of Polish environmental criminal law in international criminal law is excluded from the research. The research thesis is that the adoption of the Act on Counteracting Environmental Crime is a positive direction in combating environmental crimes. The issue of whether the current criminal law ensures the environment sufficient protection and rational management of the environment through claims protecting subjective rights requires emphasis. The issues covered by the topic are particularly valid due to the entry into force of the Act on Counteracting Environmental Crime and due to the subject of protection, which is the environment. To achieve the above-mentioned scientific results, two methods of law research were used in the work, i.e., dogmatic-legal and sociological.
Dokumentowanie oględzin miejsca zdarzenia – przesłanki koniecznych zmian

Published: October 2024

Each incident (crime or accident) leads to the creation of traces at the scene of the incident. The place is changed, and the image of these changes has great information potential. Generally speaking, the inspection of the scene of the incident is an activity aimed at disclosing, recording and securing this information. This is an activity that is complex in many respects and unique, which should be emphasized. Ergo, documenting it is crucial. Documentation of the inspection requires the form of a protocol. It is a basic document for maintaining procedural forms and making specific arrangements. The course of the crime scene investigation may also be recorded using an image or sound recording device. The cognitive value of both types of documentation is definitely different. Technical documentation has a greater cognitive potential and from the point of view of further activities, its importance is crucial, especially in the case of incident sites with a complicated factual state, extensive sites or located in hard-to-reach areas. In the study, the authors ask whether the basic form of documenting inspections fits into the realities of today’s times. Forms of communication evolve; in digital reality, the dimension and role of the written word are different. Considerations were made regarding the concept of a solution that would enable comprehensive, so to speak, documentation of crime scene investigation. It was taken into account that this is an evidentiary act, the performance of which, as well as its recording, cannot violate the rules of criminal procedure.

Published: October 2024

Introduction/Main Objectives: This study aims to test whether the assessment of the business feasibility study with the Hamdi method consisting of Gold Value Method (GVM) and Gold Index (GI) gives the same decision results as the assessment using the conventional method consisting of Net Present Value (NPV) and Profitability Index (PI). This research tries to test Mr. Zulkifli's oil palm plantation business plan in Kampar Riau. The results of this assessment will be useful as a consideration in making business development decisions. Background Problems: NPV is not used is the prohibition of interest, which is applied in both Islam and Christianity. Riba or riba refers to the charging of interest at any level, whereas modern beliefs impose interest at an unfair and disproportionate rate  and develop in parallel with the periodic interest gain. Novelty: The Hamdi method presents a viable option for assessing the feasibility of a business from a financial perspective and contributes to the calculation methods that exist in this domain. Research Methods: This study uses descriptive and quantitative analysis of the feasibility of Mr. Zulkifli's oil palm plantation business, which is assessed based on conventional and sharia aspects. The feasibility analysis assessment is based on the conventional perspective, namely NPV, and PI. The feasibility assessment is based on Hamdi's Method, namely the GVM and the GI Method. Finding/Results: The findings show that the results of the feasibility decision using GVM are in line with the NPV calculation, and the results of the feasibility decision using GI are in line with the PI calculation. Conclusion:  Hamdi's method is feasible for assessing the feasibility of a business from a financial aspect. Research limitation/implications: Hamdi's method is still not well-known and needs to be introduced to other researchers.

Authors:   Astana IT University, Abutalipova Sh.U.
Published: October 2024

Let $k[x_1,x_2,x_3]$ be an algebra of polynomials in variables $x_1,x_2,x_3$ over an arbitrary field $k$ of characteristic $0$ In this paper we consider triangular derivations of the form $D=\alpha x_2^l x_3^m \partial_1+\beta x_3^n \partial_2+\gamma \partial_3,$ where $\alpha ,\beta ,\gamma \in k$, of the algebra $k[x_1,x_2,x_3].$ It is well known that triangular derivations of the algebra $k[x_1,x_2,x_3]$ are locally nilpotent. The algorithm of A. van den Essen for computing the kernel of locally nilpotent derivation of the polynomial algebra $k[x_1,x_2,\ldots,x_n]$ in variables $x_1,x_2,\ldots,x_n$ over a field $k$ of characteristic $0$ uses the map of J. Dixmier. M. Mayanishi’s theorem states that the kernel of locally nilpotent derivation of the algebra of polynomials in three variables over the field of characteristic 0 is the algebra of polynomials in two variables. In this paper, a completely new algorithm for computing the kernel of triangular derivation of the algebra of polynomials of rank 3 over a field of characteristic 0 is constructed.

This research aims to analyze the existing situation regarding the instruction of language techniques used in flute education. It was a descriptive-based qualitative study conducted using the case study pattern one of the qualitative research methods; therefore, a semi-structured interview form was prepared as the data collection tool.
The population of the study consisted of flute teachers teaching in the Departments of Music Education of the Faculties of Education in Turkiye. In the research, a specific sampling method has not been preferred, and an attempt has been made to reach the entire population. Accordingly, all flute teachers teaching in the Departments of Music Education affiliated with the Faculties of Education at the universities that approved the study were contacted, and the study was conducted with 12 flute teachers who voluntarily agreed to participate. The data obtained with the interview form were analyzed by content analysis.
The study concluded that all twelve participants included the topic of tongue techniques in the flute curriculum for eight semesters. Some participants used the "demonstration method" while others used the "lecturing method" to teach tongue techniques. Most of the flute teachers did not utilize teaching materials for tongue technique instruction. The syllables "tu, tu-ku, tu-ku-tu" were commonly used by flute teachers. The "Taffanel" sourcebook was the most frequently used resource for teaching tongue techniques. None of the teachers employed Turkish methods, and the problems encountered in relation to tongue techniques were often attributed to issues with hand and tongue coordination.

Európát és az Európai Uniót az elmúlt években számos válság és megoldandó problémák érték. Talán a második világháború óta még sosem volt ennyire kiszámíthatatlan Európa biztonsága. Az orosz–ukrán háború és az azt megelőző konfliktusok rámutattak arra, hogy a kibertérben nemcsak az egymással ellenségeskedő felek számíthatnak fokozott támadásokra, de harmadik felek is, leginkább azon országok, amelyek valamelyik háborús fél ellátási láncának részét képezik. Ezért Európa és az Unió védelmi képességét folyamatosan fejleszteni kell, és valamennyi tagállam közreműködésével egységes, magas szintű rezilienciát kell megvalósítani több területen is. Elsődlegesen a kritikus infrastruktúrák tekintetében, amelynek védelmével a CER EU-s irányelv foglalkozik, valamint a kiberbiztonság területén kell egységes magas védelmi képességet létrehozni, amelynek alapjait a NIS2 irányelv hivatott megteremteni.

The Failure of Public Higher Education Reform in North America and Western Europe: The Need for a New Beginning
Authors: Greenwood Davydd
Published: October 2024

A consistent set of criticisms of the organisation, dynamics, and failings of public higher education (HE) has been articulated since the early 1990s. Most are on target and point to a system in freefall—expensive, ineffective, and unsatisfactory for students, faculty, many staff members, and the relevant communities they serve. Despite this, the situation in HE in North America and Europe has only worsened as neoliberal management continues to intensify management by the numbers, control of student and faculty speech, administrative bloat, and increases in tuition costs. The consequent decline in public and employer support and the approaching significant decline in birth rates, and consequently in the number of college-age students in Western industrialised countries, have not moved the powerholders in these institutions to reform the institutions in fundamental ways. I argue that piecemeal public university reforms no longer hold any promise. Only a fundamental re-creation of public HE will change the situation. This re-creation must be based on open systems dynamics, transdisciplinarity, and a focus on sustainability for the stakeholders (the faculty and students, the surrounding communities, and the larger planetary ecology). The chapter closes with an examination of what such public institutions might be like.
Indigenous Knowledge for Sustainable Change in Higher Education: An Opportunity Not to Be Missed for Humankind
Authors: Santos Doris
Published: October 2024

Across my 30-year journey through higher education (HE), I have had the honour to learn from and with members of several Indigenous peoples in Colombia. I bear this in mind while appreciating the valuable opportunity that HE offers for human beings— to explore broader ways of understanding life and the problems affecting us all, and to co-construct alternative solutions. I argue it is not enough to simply acknowledge Indigenous knowledge (IK) in institutional discourses; these intentions for inclusion need to be translated into institutional actions. Academics must leave their comfort zones and begin an authentic dialogue as praxis with Indigenous and Afrodescendant peoples to imagine and help cultivate the better world we all desire. An intergenerational strategy can make our collaborative efforts sustainable through participatory intercultural education actions. To this end, HE institutions need to strengthen institutional governance through more inclusive participation in decision-making. Collaborative actions need to leave behind competitive models to re-signify the ‘higher’ component so long distorted in HE. These actions must aim to transform realities through university–school partnerships, and collaborative work with diverse cultural communities and entities at different levels. Practical suggestions include exploring with student teachers creative and innovative initiatives to support the school system. These initiatives need to co-create with diverse cultural communities a wide range of intercultural educational bridges and pathways, aimed at preserving and strengthening Indigenous students’ cultural identities in their transition to HE and throughout their academic journey.
Nikaia'nın (İznik) Roma Sikkeleri Üzerindeki Mimari Betimlere Dair Bir Değerlendirme
Authors: Nikolayidis Haralambos
Published: October 2024

Sikkeler üzerindeki yapı betimleri Roma Cumhuriyet Dönemi itibariyle bir yenilik olarak ortaya çıkmıştır. İmparatorluğun kurulması ve yayılması aşamasında bu gelenek eyaletteki kentlerde de uygulanmaya, kabul görmeye ve yayılmaya başlamıştır. Bu geleneğin eyaletlerde uygulanması bağlamında Bithynia et Pontus Eyaleti uygun bir örnek teşkil etmektedir. Bu hususta gerçekleştirilen çalışmalar eyaletteki birçok kentin sikkelerinde yapı betimlerinin kullanılmış olduğunu ortaya koymaktadır. Bithynia Krallığı itibariyle bölgenin önemli kentlerinden Nikaia’nın zengin sikke repertuvarında MS 1. yy. itibariyle çeşitli yapı betimleri kullanılmaya başlanmış ve MS 3. yy.’a kadar devam etmiştir. Söz konusu yapı betimleri çeşitlilik göstermektedir; bir tarafta tapınak, sur, altar gibi tanımlanmaya açık yapılar yer almaktayken, diğer tarafta günümüz kalıntılarının kısıtlı olması nedeniyle kesin bir şekilde tanımlamanın yapılması güç olan yapılar yer almaktadır. Bu çalışmada kullanılan yapı betimleri gruplandırılarak kendi başlıkları altında kronolojik olarak ele alınmaktadır. Ayrıca kent sikkelerinde betimlenen yapıların Nikaia ile olan ilişkisi araştırılırken literatürdeki mevcut durum ortaya konulmaya, yapı betimleri tanıtılmaya ve güncel araştırmaların ışığında değerlendirilmeye ve yeni öneriler getirilmeye çalışılmaktadır.
New approaches to standard of care in early-phase myeloproliferative neoplasms: can interferon-α alter the natural history of the disease?
Authors: Pasquier Florence , Pegliasco Jean , Martin Jean-Edouard , Marti Severine , Plo Isabelle
Published: October 2024

The classical BCR::ABL-negative myeloproliferative neoplasms (MPN) include Polycythemia Vera (PV), Essential Thrombocytemia (ET), and Primary Myelofibrosis (PMF). They are acquired clonal disorders of the hematopoietic stem cells (HSC) leading to hyperplasia of one or several myeloid lineages. MPN are caused by three main recurrent mutations, JAK2V617F and mutations in the calreticulin (CALR) and the thrombopoietin receptor (MPL) genes. Here, we review the general diagnosis, the complications, and the management of MPN. Second, we explain the physiopathology of the natural disease development and its regulation, which contributes to MPN heterogeneity. Thirdly, we describe the new paradigm of the MPN development highlighting the early origin of driver mutations decades before the onset of symptoms and the consequence on early detection of MPN cases in the general population for early diagnosis and better medical management. Finally, we present the interferon alpha (IFNα) therapy as a potential early disease-modifying drug after reporting its good hematological and molecular efficacies in ET, PV and early MF in clinical trials as well as its mechanism of action in pre-clinical studies. As a result, we may expect that, in the future, MPN patients will be diagnosed very early during the course of disease and that new selective therapies under development, such as IFNα, JAK2V617F inhibitors and CALRmut monoclonal antibodies, would be able to intercept the mutated clones.
Diagnosis of myelodysplastic syndromes: the classic and the novel
Authors: Oster Howard S. , Van de Loosdrecht Arjan A. , Mittelman Moshe
Published: October 2024

The Myelodysplastic syndromes (MDS) are a heterogenous group of clonal bone marrow (BM) stem cell myeloid neoplasms, characterized by bone marrow (BM) dysplasia, macrocytic anemia or cytopenia with a tendency for leukemic transformation. The suspicion of MDS is raised by a typical but not specific clinical picture and routine labs, but the gold standard for MDS diagnosis is still BM examination with the presence of uni-or multi-lineage dysplasia and blast percentage, together with exclusion of other reasons. Cytogenetics is also a part of the diagnostic process. Flow cytometry and genetics are helpful but are not always mandatory for MDS diagnosis.This review summarizes the current steps in the diagnostic approach for a patient suspected of having MDS. We also describe new concepts that use non-invasive diagnostic technologies, especially digital methods as well as peripheral blood genetics. The hope is that one day these will mature, be introduced into clinical practice, and perhaps in many cases even replace the invasive BM biopsy.
