Intellectual Budapest, Hungarian Experience and the Republic of Science : Some Different Faces in Mihály Polányi’s Thinking
Authors: Kiss Endre
Published: January 2023

The intellectual life in Budapest, since the turn of the twentieth century, developed in fact a hardly evident wealth of intellectual movements. The contours of the fundamental model of Budapest’s intellectual history of that time have been drawn by the interaction of two components. Despite the unavoidable generalization, the following thesis can be presented: the contents of the three “non-simultaneous” great waves of the European Modern Age revealed as “simultaneous” phenomena in the politics, science and aesthetics in the Budapest context. Tacit knowledge was the focus of interest in the second period of Polányi’s sociology of knowledge. He explained the concept, the mechanisms, and the functions of tacit knowledge in several studies and with complete persistence. The process described by Polányi is a ‘real process’. But not a real process can not become the criterion of truth or the foundation of a conception of truth. Most social scientists of that age held the opinion that the fact that the representatives of the Hungarian 1956 formulated and represented values in an explicit way made the judgement of the events impossible as it would violate Max Weber’s principles of value-free judgments. We believe that the evidence of ‘moral truth’ could be based more successfully on so-called fundamental consensus. i.e. consensus in basic values than on the universal truth approach of the sociology of knowledge. One of its constituents has already been mentioned: neither concept of evidence can avoid relativism. Scientific communities also have their own history. Thomas S. Kuhn’s concept of paradigms changed the situation dramatically. It settled scientific communities in the decisive position of scientific production. This theory liberated science very rapidly, also in practice. In this Kuhnian framework was born Polányi’s vision of democracy in the sciences. We don’t know what Polányi would say about our new trends. Certainly, he would stick to his special liberal position.

A New Weighted Skew Normal Model
Authors: Naghibi Forough , Alavi Sayed Mohammad Reza , Chinipardaz Rahim
Published: January 2023

Weighted sampling is a useful method for constructing flexible models and analyzing data sets. In this paper, a new weighted distribution of skew normal is introduced with four parameters. The proposed model is a generalized version of several distributions, such as normal, bimodal normal, skew normal and skew bimodal normal-normal. This weighted model is form-invariant under proposed weight function. The basic characteristics of the model are expressed. A method has been used to generate data from the model. The maximum likelihood estimations of parameters are given and evaluated using simulation study. The model is fitted to the three real data sets. The advantage of the proposed model has been shown on the rival distributions  using appropriate criteria.

In this work, we derive and study a new weighted G family of continuous distributions called the new weighted generated family (NW-G). We study some basic properties including quantile function, asymptotic, the mixture for CDF and pdf, residual entropy, and order statistics. Then, we study half-logistic distribution as a special case with more details. Comprehensive graphical simulations are performed under some common estimation methods. Finally, two real-life data sets are analyzed to demonstrate the objectives.
Estimation of Zero-Inflated Population Mean with Highly Skewed Nonzero Component: A Bootstrapping Approach
Authors: Paneru Khyam , Padgett R. Noah , Chen Hanfeng
Published: January 2023

This paper adopts a bootstrap procedure in the maximum pseudo-likelihood method under probability sampling designs. It estimates the mean of a population that is a mixture of excess zero and a nonzero skewed sub-population. Simulations studies show that the bootstrap confidence intervals for zero-inflated log-normal population consistently capture the true mean. The proposed method is applied to a real-life data set.

About existence of the limit to the average time profit in stochastic models of harvesting a renewable resource
Authors: Chernikova Anastasia V.
Published: January 2023

We investigate population dynamics models given by difference equations with stochastic parameters. In the absence of harvesting, the development of the population at time points k=1,2,... is given by the equation X(k+1)=f(X(k)), where X(k) is amount of renewable resource, f(x) is a real differentiable function. It is assumed that at times k=1,2,... a random fraction ω∈[0,1] of the population is harvested. The harvesting process stops when at the moment k the share of the collected resource becomes greater than a certain value u(k)∈[0,1), in order to save a part of the population for reproduction and to increase the size of the next harvest. In this case, the share of the extracted resource is equal to l(k)=min{ω(k), u(k)}, k=1,2,.... Then the model of the exploited population has the form
X(k+1)=f((1-l(k))X(k)), k=1,2,...,
where X(1)=f(x(0)). For the stochastic population model, we study the problem of choosing a control u=(u(1), …, u(k),…), that limits at each time moment k the share of the extracted resource and under which the limit of the average time profit function
H((l)̅, x(0))≐lim┬(n→∞)⁡〖∑^n_k=1▒〖X(k)l(k), где 〗〗(l)̅≐(l(1),…, l(k),…)
exists and can be estimated from below with probability one by as a large number as possible. If the equation X(k+1)=f(X(k)) has a solution of the form X(k)≡x^*, then this solution is called the equilibrium position of the equation. For any k=1,2,..., we consider random variables A(k+1,x)=f((1-l(k))A(k,x)), B(k+1,x^*)=f((1-l(k))B(k,x^*)); here A(1,x)=f(x), B(1,x^*)=x^*. It is shown that when certain conditions are met, there exists a control u under which there holds the estimate of the average time profit
1/m∑^m_k=1▒〖M(A(k,x)l(k))≤H((l)̅, x(0))≤1/m∑^m_k=1▒〖M(B(k,x^*)l(k)),〗〗
where M denotes the mathematical expectation. In addition, the conditions for the existence of control u are obtained under which there exists, with probability one, a positive limit to the average time profit equal to
H((l)̅, x(0))=lim┬(k→∞)⁡〖MA(k,x)l(k)=〗lim┬(k→∞)MB(k,x^*)l(k).
Assessment of response to liver directed radiation-based therapies: Current guidelines, challenges, and future directions
Authors: Banda Anisha , Johnson Guy , Cunha Guilherme Moura
Published: January 2023

Radiation-based local-regional therapies for hepatocellular carcinoma (HCC) have gained wide acceptance due to promising rates of tumor response, survival, and safety profiles. After treatment, it is important to assess tumor response to determine further management, patient prognosis, and endpoint outcomes for clinical trials. To standardize imaging interpretation and reporting of HCC response to local-regional treatment, a few imaging-based response assessment systems were developed. Two of them have emerged as the most used: the Liver Imaging Reporting and Data System (LI-RADS) Treatment Response Algorithm (LR-TRA) and the modified Response Evaluation Criteria in Solid Tumors (mRECIST). While these systems have been validated for the assessment of response to ablative locoregional therapies, assessment of response to radiation-based therapies can be challenged by persistent or evolving imaging features and is still an area of active research. Following the advances in technology and a better understanding of tumor biology that allowed for the increased application of radiation-based local-regional therapies for the treatment of HCC, research is still needed to address the limitations of current imaging criteria for assessing tumor response to these novel techniques. In this review, we describe radiation-based liver-directed treatment options, examine imaging criteria for assessing treatment response, discuss practical limitations and gaps in knowledge when applying these response criteria, and address future directions that may help to improve accuracy and outcomes when assessing response to radiation-based HCC treatment.

‘Global Warming’ and the Energy Transition (Foreign Trade Aspect)
Authors: Korolev I.
Published: January 2023

Last 10‒15 years ‘global warming’ is presented as the main threat to humanity, allegedly more dangerous than a possible nuclear catastrophe. To counteract ‘climate change’ an energy transit mechanism has been launched on national and international levels. Among its aims ‒ phasing out traditional energy resources, reducing output of other products with an intensive carbon emission, forced despite the costs, transition to renewable energy resources. To achieve these aims a lot of measures are examined including EU possible applying the Carbon Border Adjustment Mechanism which may be interpreted as a trade war instrument. Many such measures contradict the United Nations Framework Convention on Climate Change (1992) the aims of which were formulated as to avoid dangers for production and sustainable growth especially for developing countries. One-sided energy transition may destabilize the situation at world markets and destroy international trade system based on WTO principles. Possible counteractions of Russia should be determined first of all by the aims of supporting its competiveness. This implies in particular the use of traditional energy resources (oil, gas, coal) in Russian economy as long as possible. Critical attitude to the prevailing international climate agenda does not mean that the author underestimates the importance of environmental issues for Russia. The close-down of many factories after the collapse of the Soviet Union diminished pollution in some places. But new dangers have appeared ‒ privately owned vehicles, urban solid waste, abandoned farmersʹ lands, ill-conceived and even criminal lodging construction. Speaking of numerous environmental and biodiversity metrics, our country fails to keep pace with advanced standarts. Even under Western sanctions Russia should increase financial outlets in order to improve environmental situation in the country. More effective ecological laws are badly needed not only in industry and transport but also in regional and municipal development.
The Russian Approach to the Soft Power Concept
Authors: Kosiakina A.
Published: January 2023

The article is devoted to a comprehensive study of the Russian ‘soft power’ policy. The author gives her view on the ‘soft power’ phenomenon and practices and draws the line between related concepts of ‘soft power’ and ‘public diplomacy’, all while explaining the reasons for the special interest of the Russian central authorities in the concept for the last two decades, which is embodied in doctrinal documents on foreign affairs. Distinctive features of the country’s understanding of ‘soft power’ and its politics are highlighted.The institutional approach and organizational theory are widely used in the article. With their help, the activities of the main ‘soft power’ institutions functioning in Russian Federation, such as Rossotrudnichestvo (The Federal Agency for the Commonwealth of Independent States Affairs, Compatriots Living Abroad, and International Humanitarian Cooperation), Russkiy Mir Foundation and the Gorchakov Fund are analyzed.The author comes to the conclusion that the lack of a clear formal distribution of responsibilities between departments leads to interdepartmental inconsistency and even competition and significantly reduces the undoubted positive effect of their work.Besides, the article pays special attention to the tools and resources of the Russian ‘soft power’ policy. Apart from traditional tools like language, education, cultural and historical heritage, such new ones that have intensified or appeared due to COVID-19 pandemic are as follows: humanitarian aid and ‘vaccine diplomacy’. And finally, the author gives a forecast on Russian ‘soft power’ in connection with the events on the territory of Ukraine and comes to the conclusion that in the coming years it will be difficult to create an image of an attractive country abroad.
Reconstruction of the Acoustic Field Radiated Directly from a Vibrating Structure Located Near a Pressure-Release Boundary
Authors: Chen Zhimin , Zhou Daren , Lou Jingjun
Published: January 2023

Near-field acoustical holography is a powerful tool for reconstructing the three-dimensional acoustic field radiated from a vibrating structure located in free space, but it is not applicable when the source is in a half space bounded by a reflecting boundary. This paper develops a method based on half-space spherical wave function expansion for reconstructing the acoustic field radiated directly from a source located near a pressure-release boundary. First, the series of half-space spherical wave basis functions satisfying the pressure-release boundary condition is formulated. Then the acoustic field in a half space is modeled using an expansion in this basis. The expansion coef?cients are determined by solving an overdetermined linear system of equations, obtained by matching this expansion to the measured half-space acoustic pressures. The pressures radiated directly from the source can finally be reconstructed using the free-space spherical wave function expansion with the obtained expansion coefficients. Numerical simulation examples of a vibrating plate located in water near a pressure-release boundary are demonstrated to validate the proposed method. The effects of various parameters, such as the acoustic frequency, the distance between the source and boundary, and the orientation of the source surface, on the reconstruction accuracy are examined.

Authors: Babina Yu. V.
Published: January 2023

Introduction. The new personality-oriented educational paradigm assumes the ability of the educational system to continuously self-renew and manage its development in close contact with the modern labor market.Purpose setting. The quality of personnel training for the labor market of the future is the subject field of scientific research of interdisciplinary sciences, requires the operationalization of the concept of "supra-professional competencies".Methodology and methods of the study. Operationalization as a way to infer the existence and some elements of the expansion of phenomena of interest through some observable and measurable effects that they have. Results. The combination of rational and value aspects of quality in a single educational process encourages us to reconsider the role of the object in the process of education, the orientation of education on the self-realization of a person in his personal and social senses. The exceptional role and great importance of supra-professional competencies is emphasized in the light of the ecosystem approach that meets the modern paradigm of higher education.Conclusions. One of the solutions is to study and develop the theory and practice of supra-professional competencies as an additional resource for the professional development of the subject of labor. This implies comprehensive scientific research, defining methods for measuring their components and correlation with indicators that determine the demand for a future specialist and his professional development.
Problems of professional self-realization of a young scientist in the conditions of transformation of institutes of educational and scientific institutions
Authors: Abramova M. A.
Published: January 2023

Introduction. The article presents the problem of professional self-realization and self-determination of a young scientist in the conditions of transformation of educational and scientific institutions. The sharpness of it is added by the diversification of professional guidelines, supported by the vagueness of state policy in the field of fundamental science development, as well as its orientation to the use of quantitative assessment parameters.Purpose setting. The problem of professional self-determination and self-realization of a young scientist is considered not through the prism of postgraduate training and quantitative criteria for evaluating its effectiveness, but through the analysis and comparison of the dominant motives for carrying out research activities by young scientists, both in Russia and abroad, as well as the factors that determine its formation. This angle of the study represents the novelty of the work.The research methodology is based on the application of structural-functional and institutional approaches, as well as theories that reveal the process of self-determination, self-realization and motivation.Results. The author provides a wide range of examples of studying the phenomenon of self-realization in the scientific environment, both by Russian and foreign researchers. It shows the general and particular that distinguishes the process in Russia and other countries.Conclusions. The main problem of self-determination and self-realization is not so much the satisfaction of material needs as the strengthening of the meaning- forming component of research activity. It should be supported by transparency of criteria focused on the evaluation of the process, the development of the professional environment of interaction, including through improving the social status of scientists representing the middle age group. In this case, it will create prerequisites for young researchers to be confident in the future in science and education.

Voltage Lifting Techniques for Non-isolated DC/DC Converters
Authors: Alkhaldi Abdulaziz , Elkhateb Ahmad , Laverty David
Published: January 2023

This paper presents a comprehensive review that highlights the characteristics of non-isolated step-up converters based on high boost voltage lifting techniques. The paper categorises the high boost techniques: multistage/multilevel, switched capacitor, voltage multiplier, voltage lift, switched inductor, and magnetic coupling. The paper also discusses in detail the advantages and disadvantages for each category such as cost, complexity, power density, reliability and efficiency. The number of passive and active components, voltage gain, voltage stress, switching frequency, efficiency and power rating are also compared. Although the paper considers coupling inductors in the context of the non-isolated converter, the focus of the entire article is on the non-isolated high voltage step-up techniques. The key contribution in this paper is the review of high boosting techniques rather than the DC /DC converters. This allows divergence of new ideas and new power converters that will help provide highly efficient and flexible power converters for several applications where the sending end voltage is very low as photovoltaic systems. In addition, many applications and control techniques of DC/DC converters are summarised in this paper.

Patients with pT1 high-grade (HG) bladder cancer (BC) and a very high risk of progression might benefit from immediate radical cystectomy (RC), but this option remains controversial. Validation of a standardized method to evaluate the extent of lamina propria (LP) invasion (with recognized prognostic value) in transurethral resections (TURBT) specimens is still needed. The Rete Oncologica Lombarda (ROL) system showed a high predictive value for progression after TURBT in recent retrospective studies. Our aim was to validate ROL system on a large mono-institutional prospective series of primary urothelial carcinomas. From 2016 to 2020, we adopted ROL for all patients with pT1 HG BC on TURBT. We employed a 1.0-mm threshold to stratify tumors in ROL1 and ROL2. A total of 222 pT1HGBC were analyzed. Median age was 74 years, with male predominance (73.8%). ROL was feasible in all cases: 91 cases were ROL1 (41%) and 131 ROL2 (59%). At a median follow up of 26.9 months (IQR 13.8-40.6), we registered 80 recurrences and 40 progressions. ROL was a significant predictor of tumor progression at both univariable (HR 3.53; CI 95% 1.56 – 7.99; p<0.01) and multivariable (HR 2.90; CI 95% 1.25 – 6.75; p=0.01) Cox regression analyses. At Kaplan-Meier estimates, ROL showed correlation with both PFS (p=0.0012) and RFS (p=0.0167). Our results confirmed the strong predictive value of ROL for progression on a large prospective series. We encourage the application of ROL for reporting the extent of LP invasion, substaging T1 HG BC, and improving risk tables for urological decision making.
Proposal of a Maturity Model for Supply Chain Sustainability
Authors: Correia Elisabete , Garrido-Azevedo Susana , Carvalho Helena
Published: January 2023

Nowadays, frameworks and models are critical to enabling organizations to identify their current sustainability integration into business and to follow up on these initiatives over time. In this context, the maturity models offer a structured way of analyzing how a supply chain meets specific sustainability requirements and which areas demand attention to reach maturity levels. This study proposes a five-level maturity model to help supply chains identify their level of engagement with sustainability practices combining three perspectives: intra and inter-organizational sustainability practices, triple-bottom-line approach and critical areas for sustainability. All the steps followed in constructing the maturity model were based on a literature review, and case studies supported its improvement, application, and testing. The proposed model presents many advantages, such as being used as a self-assessment tool, a roadmap for sustainability behaviour improvement, and a benchmarking tool to evaluate and compare standards and best practices among organizations and supply chains.
The Novelty of mRNA Vaccines and Potential Harms: A Scoping Review
Authors: Halma Matthew , Rose Jessica , Jenks Alan , Lawrie Theresa
Published: January 2023

Pharmacovigilance databases are showing evidence of injury in the context of the COVID-19 modified mRNA shots. According to recent publications, adverse event reports linked to the mRNA COVID-19 products largely point to the spike protein as an aetiological agent of adverse events, but we propose that the platform itself may be culpable. To assess the safety of current and future mRNA vaccines, further analysis on the risks due to the platform itself, and not specifically the expressed antigen. If harm can be exclusively and conclusively attributed to the spike protein, then it is possible that future mRNA vaccines expressing other antigens will be safe. If harms are attributable to the platform itself, then regardless of the toxicity, or lack thereof, of the chosen payload therein, the platform may be inherently unsafe, pending modification. In this work, we examine previous studies of RNA-based delivery by a lipid nanoparticle and break down the possible etiological elements of harm.

Haruskah Tren Pembelajaran Online Dilanjutkan?: Evaluasi Pengalaman di Perguruan Tinggi Indonesia
Authors: Miftakhuddin Miftakhuddin , Purba Orinton , Saprudin Saprudin
Published: January 2023

Setelah dua tahun pemerintah Indonesia menerapkan pembelajaran daring (PD), penelitian ini mengkaji kualitas keterlaksanaannya melalui survey terhadap mahasiswa di sembilan perguruan tinggi Indonesia. Penelitian ini dilaksanakan secara kualitatif dalam desain survei. Penelitian ini melibatkan 516 mahasiswa sebagai sample (terpilih secara random). Mereka berpartisipasi dengan mengisi angket yang telah diuji validitas dan reliabilitasnya menggunakan Aiken’s validiy index dan Cronbach’s Alpha. Data dianalisis secara deskriptif kualitatif dengan merujuk Critical Success Factors (CSFs). Penelitian ini menyoroti temuan berupa keunikan komitmen dan preferensi mahasiswa selama berpartisipasi dalam PD. Keunikan tersebut utamanya tampak dalam prioritas mahasiswa dalam PD. Mereka berpartisipasi bukan untuk memperoleh pengalaman belajar yang bermakna, melainkan pada pengisian daftar hadir dan submission tugas. Tren ini terjadi baik pada mahasiswa yang berkuliah secara fulltime maupun parttime. Oleh karena itu, sangat rumit untuk menentukan apakah mahasiswa berkomitmen atau tidak. Sepintas, mahasiswa tampak tidak serius dalam PD dengan mengakui bahwa mereka tidak ikut PD secara fulltime karena punya aktivitas lain yang lebih penting, merasa bosan, dan merasa sudah memahami materi. Namun di waktu yang sama, mereka juga menginginkan PD dilanjutkan seandainya pandemi telah usai. Penelitian ini menemukan bahwa komitmen dan preferensi mahasiswa di atas bukan hanya berkait erat dengan hambatan umum, melainkan juga dipengaruhi kompetensi dosen dalam menyelenggarakan PD. Penelitian ini merekomendasikan otokritik pendidikan tinggi atas ketidaksiapan PD ditinjau dari tiga aspek.

Faktor geologi menyebabkan aliran air kawasan karst terkonsentrasi di bawah permukaan sehingga masyarakat sulit dalam mengakses air. Seperti pada wilayah Daerah Tangkapan Air (DTA) Kakap yang terletak di Kecamatan Giriwoyo, Kabupaten Wonogiri, Jawa Tengah. Masyarakat pada setiap tahunnya mengalami permasalahan pada ketersediaan air. Sistem hidrologi kawasan karst juga dapat terancam karena kurangnya pengetahuan terhadap keberadaan ponor/luweng. Kondisi Ponor/luweng sendiri menjadi kurang terawat dengan dipenuhi banyak sampah baik sampah organik maupun sampah rumah tangga. Pengabdian ini bertujuan untuk meningkatkan kapasitas dan partisipasi masyarakat dalam konservasi di kawasan karst. Melalui Focus Group Discusion (FGD) secara partisipasi, untuk memberikan pemahaman tentang kerentanan kawasan karst sumber utama air bersih. Kapasitas masyarakat dalam mitigasi bencana kekeringan belum terbentuk dengan sempurna akibat kurangnya kesadaran dan pengetahuan akan upaya mitigasi yang dapat dilakukan secara gotong royong oleh masyarakatAbstrak dalam bahasa Indonesia mengikuti kaidah dalam Pedoman Umum Ejaan Bahasa Indonesia (PUEBI).

Introduction. To improve the power quality of a supply system, the total harmonic distortion (THD) is the most important parameter in the quantification of harmonics caused by nonlinear loads. In practice, it must be less than 5 %. The novelty of the proposed work consists in the use of a cascaded five level active filter, when the converter consisting of six H-bridge pairs, each one includes four transistors. Purpose. To increase the efficiency of this filter, two techniques for quantification of harmonic currents are proposed, first the PQ-theory which is simple but can only be used in case of a balanced grid, and second the synchronous reference frame theory (SFR-theory), which is capable of creating harmonic current not only in an unbalanced grid, but also in an unbalanced and distorted beam. Methods. Using the control techniques, the harmonic current is extracted from load current and considered as a reference. The constructed current should follow this reference. Results. The estimation of the active and reactive powers is based on the measurement of the currents crossing the load and the network voltages, these powers are used to determine the shape of the harmonic (reference) current. Using the PI regulator, the output current of the five-level inverter follows the reference current perfectly. The inverters output current is injected into the grid to eliminate harmonic currents. Practical value. In practice, the harmonic distortion rate THD is the most widely used criterion for criticizing the waveform of the currents and judging the quality of the energy involved. For currents on the source side, the THD is considered acceptable if it is less than 5 %, in our proposal the THD is 0.85 % with the PQ-theory and 2.34 % with SFR-theory, so it is optimal.

Introduction. In recent years, numerous non-renewable and renewable energies are connected to the grid to meet the demand. Also, transient variation with loads poses the shortcomings for generating units, transmission and distribution networks. In this regard, the study on choice of suitable load modelling is essential to predict the system characteristics. The aspect of the research design is a ZIP load model, which, when combined with contingency criteria and constant-impedance, constant-current, and constant-power loads, produces realistic and long-term load representations. Purpose. The proposed technique, infers the single transmission line outage for obtaining the contingency ranking to ensure the system behavior. Methods. The proposed mathematical model with hybrid line stability ranking index has been used for observing the stability analysis with and without considering unified power flow controller. Results. The power system involves many unpredictable conditions or contingency conditions like single transmission line outage, double transmission line outage, generator outage and load variations. This paper mainly focuses on the single transmission line outage for obtaining the contingency ranking. Practical value. The recommended stability analysis has been very beneficial in establishing a secure transmission power system.
REPEATED WASTE OF HUMATIVES INTO PLAIN METALS IN THE PURIFICATION OF WEAKLY ACID WATER, TO CLEAN Cu2+, Pb2+
Authors: Rudneva K.
Published: January 2023

Destroyed military and industrial facilities have grave consequences not only for the country's economy, but also for the environment and natural resources. At present, humic acids are quite well known and have been sufficiently studied by the natural sorbent. Due to a wide range of functional groups, they perform accumulative, transport, regulatory, protective and physiological functions. The interaction of metal ions with humates does not have a single clear described mechanism. This is facilitated by the complexity and diversity of the structure of humic acids, as well as various reaction conditions in laboratory and natural conditions. Therefore, ways to increase the efficiency of sorption, improve and search for new properties of these substances still remain relevant.

In this work, the possibilities of reverse bonding of copper and lead ions in slightly acidic aqueous solutions at pH values of 4,4–6,3 are shown. Humic acids were isolated from peat and brown coal, and potassium humates produced in China were also used. In this study, model solutions of copper (II) sulfate and lead (II) acetate were used with a calculated concentration in terms of copper and lead of about 400 and 1000 mg/dm3, respectively. The regeneration of metal humate complexes was carried out by lowering the pH of the medium to 2,1–2,2. The degree of lead sorption was 97–99 % for Pb2+ solutions with a concentration of 216 mg/dm3. Studies have shown the effectiveness of re-use of regenerated humates with a degree of metal release of 85–91 % in relation to the sorbed amount.

The metal content in the experiment was determined by inductively coupled plasma atomic spectroscopy.

It was also found that the ratio of the average values of the specific sorption of lead and copper was from 2,8 to 3,1 for various types of humic acids (humates). The proximity of these values with respect to the atomic masses of lead and copper (3,3), in the author's opinion, is associated with the interaction of copper and lead ions with humates in a stoichiometric ratio due to a chemical reaction (reactions). The sorption given in the experiment is described by a linear dependence in the coordinate system: the mass of the sorbed metal (ions) – the mass of humates.
Succession and Transfer of Agricultural Land Holding: Evidence from Slovakia

The number of farmers in the European Union is gradually declining due to weak incentives, especially for the younger generation, to work in agriculture. State intervention is therefore essential for the preservation of farms in the form of legal regulation of succession as well as the creation of a supportive environment for successor entities to be able to continue agricultural production effectively. The aim of this paper is therefore to assess the sustainability potential of agricultural holdings on the basis of an analysis of the legislation on the succession and transfer of agricultural land holdings to physical and legal persons. In this article, we used traditional legal methods of examining legal regulations based on grammatical, logical, systematic, and teleological interpretations. The results show that in Slovakia there is currently no specific legal regulation by the state that would address the succession of agricultural land and agricultural enterprises in a targeted manner.
