A simple algorithm for determining the set of parameters of the equivalent circuits of the impedance of a planar conductometric transducer with an interdigital comb topology, consisting of interelectrode and Faraday impedances is proposed. The frequency characteristics of the impedance parameters of the transducer samples and the electrical equivalent with averaged values of the parameters have been studied. A technique for determining the parameters of a three-element equivalent circuit, including solution resistance, double layer capacitance, and charge transfer resistance, has been developed and tested on a series of transducer samples. The optimal operating frequencies of the impedance-measuring channel are determined, and its schemes are developed. A technique for estimating the parameters of the Warburg impedance of transducer samples is demonstrated. The results obtained in the work make it possible to determine the optimal operating frequency range of biosensor systems and reduce errors from the influence of the Faraday impedance. The possibility of extending the functions of such transducers by using the near-electrode layer impedance parameters as informative ones is shown.

Establishing the biopharmaceutical equivalence of generic drugs is a necessary component of the relevant drug dossier. Determination of in vitro equivalence is a test designed to assess the equivalence of the dissolution profiles of the study and reference drugs in three dissolution media with pH values of 1.2; 4.5 and 6.8. A value of f2 in the range from 50 to 100 guarantees the similarity or equivalence of the two profiles and the equivalence of the pharmacological action of the test drug and the reference drug. A method for the quantitative determination of the fabomotizole dihydrochloride by spectrophotometric method has been developed, which is suitable for studying the dissolution profiles of BAFAZOL IC tablets, 10 mg tablets. Measure the absorbance of the test solution and the reference solution in a 1 cm cell relative to the compensation solution at wavelength: 302 nm for 0.1 M hydrochloric acid solution and 296 nm for acetate buffer pH 4.5 and phosphate buffer pH 6 8. The method was validated on the parameters of specificity, accuracy, correctness, linearity in the studied range of concentrations. Excipients do not interfere on the determination of the fabomotizole dihydrochloride. The absorption spectra of the test solution and the reference solution coincide in nature and position of the maximum. This also confirms the specificity of the method. Linearity was investigated on model mixtures in different dissolution media inthe range of 10. – 130%. The coefficients of linear dependences in the studied concentration ranges correspond to the allowable values. The stability of the tested solutions and reference solutions in the case of their storage at room temperature for 8 hours was confirmed. The release of more than 85% of fabomotizole dihydrochloride in 15 min in all dissolution media indicates the similarity of the dissolution profiles and does not require the calculation of the similarity factor f2.
IMAGE OF PROSECUTORS AND THE PROSECUTOR'S OFFICE IN UKRAINE: A MODERN CONCEPT
Authors: Amelin O. Yu. 
Published: November 2022

The article is devoted to the study of the peculiarities of understanding the image as a concept in general and the image of prosecutors and prosecution in particular. Attention is focused on the role of the image of state bodies of Ukraine, including the prosecutor’s office, in the conditions of a full-scale military attack on Ukraine.
The tendency to the spread of information tools of commercial organizations among public authorities, in particular the prosecutor’s office, the intensification of attention of their management to the role of image and methods of effective image-making is stated. Examples of practical activities on the implementation of developments in the field of image-making among prosecutors are given.
It is determined that the image in the broadest sense includes self-image, image perceived by others and desired image. At the same time, image-making involves the purpose, strategy and tactics of forming the desired image.
It is proposed to interpret the image of prosecutors as the image of perception of their personal traits and professional qualities by others - citizens, colleagues, representatives of other bodies and institutions of the justice system. And the image of the prosecutor’s office - as a stable perception of the prosecutor’s office, which is formed both by employees in the course of their professional activities, and by the public by informing it about the activities of the institution, its mission, values, etc. It was emphasized that a properly formed image of prosecutors is an extremely important component of the successful performance of the functions entrusted to the prosecution and the effective implementation of its development strategy.
An important debatable issue of positioning the symbols of the prosecutor’s office in Ukraine as a component of its image is raised. It was found that the symbols of the Prosecutor General’s Office, which replaced the symbols of the Prosecutor General’s Office of Ukraine, represent exclusively the prosecution body of the highest level, while the regional and district prosecutor’s offices allegedly have nothing to do with it, which does not correlate well with the unity of the prosecution system of Ukraine and the unified status of all prosecutors.
Attention was focused on the need for further research of the problem of improving the methods of identifying the attitude of the society and the prosecutors themselves to the image of the department and individual prosecutors, given the dubious objectivity of such methods as questionnaires and surveys, even with the use of modern electronic tools.
FULL PROTECTION AND SECURITY STANDARD AS A PREVENTIVE TOOL FOR THE PROTECTION OF A FOREIGN INVESTOR AGAINST ILLEGAL ACTIONS OF THE HOST STATE
Authors: Petrunenko Ya. V. 
Published: November 2022

The article considers the issue of the application of the standard of full protection and security as a preventive tool for the protection of a foreign investor against illegal actions of the host state. The relationship between a foreign investor and the state-recipient of investments is not always a partnership and mutually beneficial tandem. Carrying out investment activities, moreover, in a foreign country, is a risky activity that requires the protection of the rights of a foreign investor. The standard discussed in this article has a preventive and compensatory nature, as evidenced by court and arbitration decisions. In particular, the main purpose of this standard has traditionally been to protect the investor from various types of physical violence, including the violation of investment property rights, but the concept of this standard has now evolved beyond the physical protection of the investment to include judicial and legal protection. The current state of international investment law jurisprudence regarding the full protection and security standard is not flawless, as is usually the case in jurisprudence regarding other standards. Nor is it irretrievably fragile. The standard of full protection and safety is harm; on the other hand, it was spread to legal detriment. The relationship between the standard of full protection and security based on the treaty and customary international law, which has already been repeatedly given attention by jurists, must be correlated as lex specialis, since its scope is not fully determined by customary international law as lex generalis. It may go beyond the physical and some legal protection already built into customary international law. However, compliance with the treaty-based standard of full protection and security is measured by due diligence, as is the case with the customary international law obligation to provide full protection and security to aliens.
Benefits of exploiting authentic materials for developing sociolinguistic competence
Authors: Bérešová Jana 
Published: November 2022

Being a competent user of a target language includes mastery of sociolinguistic appropriateness and cultural repertoire alongside linguistic and pragmatic competencies. The article is based on the results of an ongoing research project that seeks to explore the implications of communicative teaching at secondary schools in the local context. The article reports university students’ findings related to the development of sociolinguistic competence, gained utilising excerpting examples of natural English. An analysis of the achieved results stimulated an insight into the real language and culture, which was later reflected in the students’ performances. Contemporary literary prose offers enough authentic material to discover its benefits for developing sociolinguistic awareness and cultural repertoire. The article presents the findings that can encourage English teachers to use authentic materials in their English classes in case they have not discovered their relevance to language and culture acquisition.

Effect of nitrogen concentration and cotyledons on nitrogen preference in seedlings of Cedrus atlantica Manetti
Authors: El Amrani Belkacem , BENDRISS AMRAOUI Mohammed 
Published: November 2022

The organic matter constitutes the most important source of nitrate and ammonium in coniferous forest soil, which are the two major nitrogen forms used by plants. The preference and/or adaptation of one N-form over another by seedlings genotypes is a determinant factor in the success of reforestation programs, not only for cedar species but any other forest essence. In a controlled growth chamber, the seedlings of two provenances of Cedrus atlantica M. (Gouraud and Moudmame) are grown on natural soil or on organic matter fertilized with different N-form and concentration. Our results show a high nitrogen requirement and a different preference towards nitrogen forms which is mainly manifested at secondary roots. On the other hand, variations in the cotyledons affect the growth and the response of the seedlings to the nitrogen form and thus reveal different forms of adaptation to nitrogen nutrition which are linked to the cotyledons and to the age of seedlings. The growth response of C. atlantica to nitrogen form and concentration is discussed in light of the effect of the provenance and cotyledons. Taken together, these results suggest that knowledge of the nitrogen requirements of the different genotypes of C. atlantica at the juvenile stage could be a good tool for successful reforestation of this forest species.
Impacts du changement d’utilisation des terres sur la biomasse et la diversité dans le paysage forestier de la réserve de biosphère de Yangambi en République démocratique du Congo

Les forêts tropicales de la République démocratique du Congo sont menacées par la déforestation et la dégradation forestière, qui affectent la structure et la diversité arborée. Cette étude a pour objectif de quantifier les pertes de biomasse et de diversité liées à la déforestation et à la dégradation, en se concentrant sur la réserve de biosphère de Yangambi. Quatre parcelles de 50 m x 50 m ont été inventoriées dans chacun des huit types d’utilisation des terres identifiés : la forêt mature mixte, la forêt mature à Gilbertiodendron dewevrei, les champs des cultures vivrières, les jachères (5 à 10 ans), les forêts secondaires (20 à 40 ans), les plantations de cacaoyers, les plantations de caféiers et les plantations de palmiers à huile. Les stocks de biomasse dans les forêts matures s’élèvent à environ 400 et 380 Mg/ha respectivement pour la forêt à G. dewevrei et la forêt mixte. Les résultats montrent que la forêt mature perd 50, 70 et 90 % de sa biomasse aérienne quand elle est convertie en plantations de cacaoyers, caféiers et palmiers, respectivement, et la quasi-totalité (99 %) lorsqu’elle est convertie en champs de cultures vivrières ; mais quand le champ est abandonné, la biomasse se reconstitue progressivement à 7,5 % après 5 à 10 ans et à 38,8 % après 20 à 40 ans. La diversité est aussi impactée par la conversion, et, bien que la richesse spécifique semble se reconstituer plus rapidement que la biomasse, la composition est fondamentalement modifiée. Ces résultats fournissent des informations essentielles pour quantifier les impacts des solutions « naturelles » pour lutter contre le changement climatique : la protection des forêts matures, l’amélioration de la gestion forestière et le reboisement ; même si l’approche doit être étendue à plus grande échelle.
