Authors: Gispert-Saúch Carme Martinell , Morata García Txus , Rocha Scarpetta Joan Andreu
Published: November 2024

Introducción: El objetivo de este estudio consiste en describir los factores que influyen en los procesos de innovación social en las entidades del tercer sector. Metodología: Desde el estudio de tres casos en profundidad, se realiza una investigación cualitativa desde un abordaje de teoría fundamentada. Resultados: Se detectan once categorías que impactan en la innovación social: centralidad del usuario, cultura interna, enfoque, escalabilidad, evaluación del impacto, financiación, nivel de independencia, nivel de legitimidad, alianzas, potencial TIC y voluntariado Discusión: Las organizaciones tienen distintos avances en las distintas categorías. Sin embargo, todas ellas contribuyen al desarrollo de la innovación social. Sin una comprensión profunda de qué es la innovación social quizás no afloran las verdaderas innovaciones sociales que el tercer sector genera y puede ocultar, en comparación con otros sectores, una innovación social mayor de la supuesta.  Conclusiones: Existen cuatro tipos de factores que favorecen la innovación social en el tercer sector. Los estructurales, como un propósito claro o su gobernanza. Los factores propios o capacidades diferenciales que el tercer sector posee, como su capilaridad. Los emergentes, como nuevas tendencias tecnológicas o de  medición de impacto. Y los factores de legitimidad, incluyendo la calidad o la rendición de cuentas.

Stabilizatsiya kolebaniy upravlyaemoy avtonomnoy sistemy
Authors: Tkhay V. N
Published: November 2024

We consider a smooth autonomous system in general form that admits a non-degenerate periodic solution. A global family (with respect to the parameter h) of nondegenerate periodic solutions is constructed, the law of monotonic variation of the period on the family is derived, and the existence of a reduced second-order system is proved. For it, the problem of stabilizing the oscillation of the controlled system, distinguished by the value of the parameter h, is solved. A smooth autonomous control is found, and an attracting cycle is constructed.
Usloviya skhodimosti dinamiki refleksivnogo kollektivnogo povedeniya v modeli oligopolii Kurno pri nepolnoy informatsii
Authors: Algazin G. I , Algazina D. G
Published: November 2024

This paper considers a Cournot oligopoly model with an arbitrary number of rational agents under incomplete information in the classical case (linear cost and demand functions). Within the dynamic reflexive collective behavior model, at each time instant each agent adjusts his output, taking a step towards the maximum profit under the expected choice of the competitors. Convergence conditions to a Cournot–Nash equilibrium are analyzed using the errors transition matrices of the dynamics. Restrictions on the ranges of agents’ steps are imposed and their effect on the convergence properties of the dynamics is demonstrated. Finally, a method is proposed to determine the maximum step ranges ensuring the convergent dynamics of collective behavior for an arbitrary number of agents.
On Preset Homing and Synchronizing Sequences for Observable Input/Output Automata
Authors: Burdonov I. B. , Evtushenko N. V. , Kosachev A. S. , Kushik N. G.
Published: November 2024

The paper is devoted to the problem of deriving synchronizing and homing experiments for nondeterministic Input/Output automata; corresponding input sequences are widely used in testing (non-initialized) discrete event systems. In active testing, there is an opportunity to set a system under test into a known initial state; in passive testing, a known current state allows to reduce the number of properties to be checked. In the paper, we note that such experiments for Input/Output automata are different from so-called “gedanken” experiments with classical Finite State Machines; the existence check conditions of such experiments are established for a predefined discipline of applying inputs and a method for its derivation is proposed when such an experiment exists. The obtained results allow to reduce the problem of deriving synchronizing and homing experiments for Input/Output automata to the well developed problem of deriving such experiments for appropriate classes of Finite State Machines.

Authors: Kabanov A. A. , Zuev A. V. , Zhirabok A. N. , Filaretov V. F.
Published: November 2024

This paper considers the problem of identifying (estimating) faults in systems described by linear models under exogenous disturbances. It is solved using optimal control methods; in comparison with sliding mode observers, they avoid high-frequency switching. The solution method proposed below involves a reduced model of the original system that is sensitive to faults and insensitive to disturbances. The corresponding theory is illustrated by an example.
Density Systems: Analysis and Control
Authors: Furtat I. B.
Published: November 2024

This paper considers a class of systems called density systems. For such systems, the derivative of a quadratic function depends on some function termed the density function. The latter function is used to define the properties of the space affecting the behavior of the systems under consideration. The role of density systems in control law design is shown. Control systems are constructed for plants with known and unknown parameters. The theoretical results are illustrated by numerical simulation.

Published: November 2024

The influence of the arrangement of amino acid residues in a pentapeptide on its stability is being studied. A forecast of pentapeptide stability is made using the gradient boosting method, which allows one to evaluate the influence of each feature on the stability of the pentapeptide. Combinations of amino acid arrangements in the pentapeptide have been identified that make a significant contribution to its stability. It has been shown that the useof such combinations reduces the amount of data required to obtain a reliable prediction of pentapeptide stability.

Published: November 2024

Models and methods have been developed to verify the achievability of goals and the feasibility of plans implemented when managing large-scale systems in their development. An algorithm for analyzing the achievability of a set of goals and plans implemented when managing these systems is proposed and justified. Statements and hypotheses that make it possible to machine-check the feasibility of plans have been generated. A model example is given that confirms the possibility of checking the feasibility of plans for eliminating the consequences of a flood using the developed models and methods. In managing large-scale systems development, it is advisable to use control loops that check the achievability of set goals and the feasibility of plans over a selected time interval. In the absence of this verification, the chosen trajectory of development of a large-scale system at specific points in time may turn out to be unrealizable,which will lead to disruption of the work being carried out, as well as to significant costs of the human, financial, technical and other types of resources for the implementation of obviously impracticable plans.

Published: November 2024

A method has been proposed for the preparation of 1,10-disulfanyl-closo-decaborate anion [1,10-B10H8(SH)2]2-(3). This compound can be easily prepared in several steps. The first stage consists of selective introduction of the zwitterion of iodine at the apical vertices into the closo-decaborate anion (1,10-B10H8(IPh)2(1)). At the second stage, this group is replaced by thiodimethylformamide (1,10-B10H8(SCHNMe2)2(2)). At the last third stage, the resulting derivative undergoes hydrazinolysis at the substituted position with the formation of 1,10-disulfanyl-closo-decaborate anion. This compound in its reaction properties is very close to the substituted 2-sulfanyl-closo-decaborate anion at the equatorial position [2-B10H9(SH)]2-, which can easily undergo an alkylation reaction in the presence of a base. Bromoacetamide was used as an example, which made it possible to obtain a tetraacetylamide di-sulfonium derivative of the closo-decaborate anion (1,10-B10H8(S(CH2C(O)NH2)2)2(4)). The resulting compounds were characterized using multinuclear NMR spectroscopy on 11B, 1H, 13C nuclei, IR spectroscopy and elemental analysis. The structures of compounds 2, 3, 4 were determined by X-ray diffraction analysis. Based on X-ray diffraction data and Hirschfeld surface analysis, crystal packing and intermolecular interactions in compound 4 were studied.

New coordination compounds of light rare-earth (RE) bromides with acetylurea (AsUr) were synthesized, [Y(AcUr)2(H2O)4]1.39[Y(AcUr)2(H2O)5]0.61Br6·2H2O (I), [La(AcUr)2(H2O)5]Br3 (II), [Ce(AcUr)2(H2O)5]Br3 (III), [Nd(AcUr)2(H2O)5]Br3 (IV), [Sm(AcUr)2(H2O)5]Br3 (V); elemental analysis, IR spectroscopy and X-ray diffraction were used to determine their compositions and structural features. Compound I is built of the [Y(AcUr)2(H2O)4]3+ and [Y(AcUr)2(H2O)5]3+ cations in the 2.28 : 1; they differ by the number of the inner-sphere water molecules (4 and 5 for coordination numbers 8 and 9, respectively), non-coordinated Br— ions and H2O molecules. Compounds II and III are built of the [Ln(AcUr)2(H2O)5]3+ (Ln = La, Ce) cations and outer-sphere Br— ions. The structures changes on cooling from 296 K to 100 K being isostructural at both temperatures. Compounds IV and V have the same composition, but different structures. They also have different polymorphous modifications at 100 and 296 K. Samarium, terbium and dysprosium bromide complexes of acetyl urea show photoluminescence.

Authors: Getmanskii I. V. , Zaitsev S. А. , Koval V. V. , Minyaev R. М.
Published: November 2024

Using quantum chemical calculations performed within the framework of electron density functional theory, the structural, mechanical, thermal, electrical and optical properties of three new mixed-type supertetrahedral structures based on the diamond crystal lattice were studied, in which pairs of neighboring carbon atoms are replaced by a pair of tetrahedra, one of which consists of four carbon atoms, and the second of four boron, aluminum or gallium atoms. The calculations have shown that all three crystalline structures should be structurally stable and have a low density, and the density of the aluminum-carbon structure should be even lower than the density of water (0.97 g/cm3). The boron-carbon structure should have the highest hardness (24 GPa), the hardness of the other two structures should be four times lower. All three crystal structures should be narrow-gap semiconductors with a band gap of 0.65–1.87 eV.

Published: November 2024

The structure and properties of a three-dimensional crystal consisting of 1,6-closo-carborane have been studied using quantum chemical methods with calculations in the approximation of functional density theory and the imposition of periodic boundary conditions. Calculations of the phonon energy spectrum and electronic band structure showed that the 3D crystal is structurally stable and belongs to an indirect gap semiconductor with a band gap of ~1.44 eV. The calculated parameters of mechanical properties showed that the hardness has the same values (21.8 GPa and 25.2 GPa) according to each method of theoretical evaluation of hardness, Young’s modulus is equal to 97.24 GPa and 242.90 GPa, respectively.

Published: November 2024

The [Сu—C6F11COOAg] system was studied using thermogravimetry, differential scanning calorimetry and mass spectrometry methods. It has been established that in the temperature range 370–445 K, a solid-phase exchange reaction occurs in the condensed phase of the system with the formation of C6F11COOCu and silver. The enthalpy of this reaction was found to be ΔrHo298.15 = –17.5 ± 4.0 and the standard enthalpy of formation of a crystalline copper complex ΔfHo298.15 = –2769 ± 25 kJ/mol. Sublimation of the copper complex is accompanied by the transition into the gas phase of dimeric (C6F11COOCu)2 ΔsHoТ = 134.4 ± 7.2 kJ/mol and a small amount of tetrameric molecules (C6F11COOCu)4. The standard enthalpy of formation of the dimer complex in the gas phase was calculated to be ΔfHo298.15 = –5404 ± 26 kJ/mol. The paper examines the possibility of exothermic interaction of copper perfluorocyclohexanoate with metallic copper in the condensed phase.

Published: November 2024

A 3D model of the phase equilibrium states of the quasi-ternary system LiF-NaCl-KCl, which is a stable triangle of a four-component reciprocal system Li+,Na+,K+||F–,Cl–, is constructed. Based on the 3D model, polythermal, isothermal sections and polytherms of phase crystallization were constructed for the first time. Two polythermal sections show the presence of areas of boundary solid solutions based on sodium and potassium chlorides. On the isothermal section at 620oC, the fields of coexisting phases are delimited. The crystallization polytherm is represented by three fields of crystallizing phases — lithium fluoride and boundary solid solutions based on NaCl and KCl. The stable character of the LiF-NaCl-KCl triangle is confirmed by thermodynamic calculation for several interaction temperatures of substances included in the unstable LiCl-NaF-KF triangle. The exothermic nature of the exchange reaction is confirmed by the exoeffect on the DTA curve of heating a mixture of powders of 50 mol.% LiCl+25 mol.% NaF+25 mol.% KF. The phases formed after the reaction — LiF, boundary solid solutions based on NaCl and KCl, are confirmed by X-ray phase analysis data. A low-melting region from the melting point of the ternary eutectic (604oC) to the isotherm (650oC) is isolated on the concentration triangle, mixtures of which can be used as a functional material for various purposes.
Thermal stability of (ZnS)(Ag2S)x heteronanostructures of zinc and silver sulfides
Authors: Sadovnikov S. I. , Sergeeva S. V. , Gusev А. I.
Published: November 2024

Heteronanostructures (ZnS)(Ag2S)x with x from 0.002 to 0.50 were synthesized by hydrochemical coprecipitation. The size of ZnS nanoparticles in the resulting heteronanostructures is 2–4 nm. Annealing of synthesized heteronanostructures (ZnS)(Ag2S)x in air at temperatures from 25 to 530°C or more leads to a change in their phase composition due to the oxidation of cubic zinc sulfide to hexagonal zinc oxide. Oxidation begins at a temperature of ~250°C, and the zinc oxide content in them after annealing at 530°C reaches ~26–30 wt.%. The size of nanoparticles of the resulting ZnO ranges from 12 to 17–25 nm. A study of the oxidation of (ZnS)(Ag2S)x heteronanostructures in air showed that the initial mass loss observed upon heating to ~120°C is due to the removal of adsorbed moisture. The subsequent weight loss that occurs upon heating from ~250 to ~430–450°C is associated with the onset of oxidation of ZnS sulfide and the formation of ZnO oxide. The greatest weight loss is observed upon heating from ~450 to ~580°C and is due to an increase in the ZnO content, partial oxidation of sulfur and its removal in the form of SO2. The oxidation stages are confirmed by the presence of maxima in the temperature dependences of ion currents corresponding to H2O, CO2 and SO2. The studied heteronanostructures are thermally stable when heated to ~200–250°C.
The economy of Portugal half a century after the “Carnation Revolution”. An experience of conceptual interpretation)
Authors: Yakovlev Petr P. , Yakovleva Nailya M.
Published: November 2024

The Portuguese economy approached the 50th anniversary of the Carnation Revolution (25 April 2024) in relatively good shape. According to international analysts, the country has ceased to be the “sick man” of Europe, as it was called at the turn of the first and second decades of the 21st century, and is experiencing a “golden period” of its economic history, in particular, thanks to factors such as structural modernization, growing exports and increasing inflows of foreign tourists. But the normalization of the country’s economic situation was based on tough measures within the framework of the policy of “fiscal asceticism” carried out after the crisis of 2008-2009, and these measures cost dearly to millions of Portuguese, whose financial situation has significantly worsened and remains unstable to this day. The country also paid an expensive social price for financial and economic stabilization in the form of emigrants, whose number by 2020 exceeded two million people (about 20% of the population). Moreover, unlike previous waves of emigration, when unskilled workers left, now the bulk of those leaving the country are educated specialists. But this is just one of the new challenges to which Portugal will have to find an answer in the context of geo-economic upheavals occurring in Europe and the world.

Franco-Moldovan Relations at the Present Stage
Authors: Entina E. G , Davranova S. B
Published: November 2024

Despite the growing relevance of the case of Franco-Moldovan relations, little atten-tion has been paid to their study outside the context of European integration processes. This study seeks to fill this gap by identifying and summarizing the current status, specificity and con-text of French foreign policy in Moldova, the key interests of the parties towards each other, as well as the main challenges and tasks they are facing. The results of the study show that until 2021, the bilateral dynamic was rather inert. The Republic of Moldova (RM) did not rank high in the system of Paris's foreign policy priorities even after the sharp increase in the confrontation between the Russian Federation and the EU in 2014. Although the Moldovan vector of French foreign policy is now ranked alongside other post-Soviet countries, the results show that the starting position from which France's activation in RM began is very different from the inputs that for many years shaped the French geopolitical optics in other parts of the former USSR ‒ in the Caucasus and even in Central Asia. The year 2021 has become a reference point in this relationship because a political configuration favorable to France has begun to emerge in Moldova. For Chisinau, the need to gain favor with Paris is critical in the context of its stated goals of European integration. In the case of France, the motivation looks much more multilayered, but it is summarized by Paris's desire to take the Moldovan plot into circulation in order to reassemble its self-positioning as a leader in the EU.
Middle East “Expansion” into the Balkans
Authors: Arlyapova E. S , Ponomareva E. G
Published: November 2024

Middle Eastern players have been involved in the “Balkan game” at different times, but since the 1990s, all the key actors in the Islamic pool have been present on the regional agenda. They are most active in countries outside the EU political framework – Albania, Bosnia and Herzegovina, North Macedonia, Serbia, Montenegro and the partially recognised polity of Kosovo. At this stage, they are not entering into open competition for influence in the Western Balkans with the established leaders ‒ the EU, USA, Russia, UK and China but are actively increasing their presence. The main areas of penetration remain economic (especially the monarchies of the Persian Gulf – UAE, Qatar, Kuwait, and Bahrain), cultural-ideological (Turkey and Iran), and religious (all Middle Eastern players). The nature of relations between external players in the Balkans is adversarial. Their strategies vary but have common features: the almost simultaneous start of promotion in the region, the initial focus on local Muslim communities and the subsequent departure from the imperative of unity of faith, similar industries and methods of implementation, common risks and problems associated with them. For the most part, preference in bilateral interaction with the countries of the region is given to personal connections to the detriment of institutional, investment, and economic initiatives to the detriment of diplomatic work. Collaborative projects often lack transparency and are vulnerable to criticism and interference from more powerful external actors. However, the “soft power” policy of eastern actors is flexible and adaptive, which ensures their further consolidation in the Western Balkans.
The EU‒NATO Cooperation after the Start of the Special Military Operation
Authors: Aleshin A. A
Published: November 2024

The EU and NATO have been developing cooperation since 2002. А new stage began in 2016, as a result of which their cooperation has reached a qualitatively new level. There has been formed a single transatlantic security space, in which the EU and NATO coordinate strategic goal-setting, practical policies, and activities in the field of defence and security in a number of areas. The main focus was on hybrid threats and military mobility. The start of Russian military operation in Ukraine has become an important factor in changing the security environment in Europe and the security threats identified by the EU and NATO. The article examines the stage of EU‒NATO cooperation after February 2022. The purpose of the study is to identify trends in the development of interaction between these two structures, to determine which trend dominates: the closer partnership of the EU and NATO or the accumulation of contradictions between them. Bilateral EU‒NATO documents during the specified period were studied using the content-analysis method. It was revealed that since 2022, EU‒NATO cooperation did not move to a qualitatively new level and developed in accordance with the trends of the previous period. This is reflected in the absence of fundamentally new areas of bilateral interaction and new joint projects. The reasons for this are the existing contradictions between the two structures, studied in the article. At the same time, it was noted that despite the contradictions, there is a continuation of the development of a single transatlantic security space due to the further division of re-sponsibilities between the EU and NATO, their cooperation in areas of common interests and the increasing role of the US and NATO. This occurs in the context of identifying direct threats from third states (Russia and partly China).
Identists vs. Antiidentists: A Prologue to the Ukrainian Crisis
Authors: Lunkin R. N , Filatov S. B
Published: November 2024

The article analyzes the features of modern ideological and political conflicts in Europe and the world, in particular, the process of crystallization of the identist ideology (identism), which opposes the values of “liberal democracy” (antiidentism) on the eve of the Ukrainian crisis. It is emphasized that the struggle for identity has become a form of defending attractive meanings and defending sovereign models of development as opposed to ultraliberalism. The confrontation between traditionalists and antitraditionalists has become an integral element of the dynamics of divided societies. That context could help to understand the deepening of the ideological withstanding during Ukrainian crisis. The article examines party-political differences and ideological conflicts in the public sphere, describes the origins of the emergence of modern antiidentism, the growth of identist sentiments and the reaction to this growth from the supporters of antiidentism. The factors of weakening of identism were the struggle with political rivals, in the United States against Trump and Trumpism, in the European Union against parties and move-ments of the identism orientation (“populists”), the criminalization of identist views within the framework of the imposition of gender policy, during the pandemic the marginalization of identist principles in the context of sanitary policy. It is concluded that within the framework of the emerging polycentric world the confrontation of two ideological systems – identism and antiidentism is gradually taking shape. The most important feature of this confrontation is the significant presence of supporters of various opposing parties in almost all countries and regions of the world. All Western identists declared themselves as the unconditional supporters of democratic values in the traditional sense of classical liberalism – separation of powers, free elections, and civil liberties. They see themselves as fighters for their revival in modern Europe and in the United States, as opposed to the monopoly of antiidentism.
Ecopsychological Conceptualization of Psychological Resources in the “Person — Environment (Internal, External)” System
Authors: Panov Victor I.
Published: November 2024

The idea of a psychological resource is used mainly in relation to the behavior of an individual in difficult or problematic situations for him, when there are not enough actual abilities and subjective means for coping behavior (coping strategies) or solving the problems that arise. From the variety of definitions of psychological resources, it follows that the problem of conceptualizing psychological resources on the basis of uniform methodological premises, invariant to different types of difficult, critical situations, remains relevant. As such, to conceptualize the psychological resource in an individual’s interactions with the internal and external environment, the concepts of the “person — environment (external, internal)” system and the ecopsychological typology of agent-environment interactions, developed within the framework of the ecopsychological approach to mental development, were used. This made it possible to conceptualize ideas about a person’s psychological resource in a system of constructs located, relatively speaking: a) vertically “opportunity (personal potential) – reality (actual subjective qualities)”, and b) horizontally: “internal environment (the totality of internal, intra-subjective capabilities) — external environment (the set of external, extra-subjective conditions)”. As a result of this conceptualization, human psychological resources appear before us in the form of an eco-psychological resource of the “person-environment” system itself, which consists of an internal (intrapersonal) resource, external (external environmental) resource and communicative resource in the form of subject-environmental interactions. The implementation of an ecopsychological resource occurs as a transformation (manifestation and development) of the subjective qualities of an individual and his subjectivity in the “person — environment (internal, external)” system. Depending on the type of difficult situation (working, problematic, potentially problematic), the implementation of an eco-psychological resource can occur in a reproductive, developmental and preventive form. The presented ecopsychological conceptualization is invariant in relation to the specific content of difficult situations.
Serious Leisure As a Medium for Expressions of Agency in the Experience of Emerging Adults
Authors: Tsyganova Еkaterina M. , Bochaver Аlexandra A. , Yerofeeva Victoria G.
Published: November 2024

The serious leisure is considered as a living environment that is important for the development of agency at different ages. In the period of growing up, young people face many challenges that require them to actively make choices in the fields of education, profession, and relationships, and their previous experience of proactive interaction with the environment plays an important role, which can be relied upon when making responsible decisions. An important environment for the trial and implementation of agency can be the sphere of serious leisure as an activity that requires effort and long-term involvement and at the same time is characterized by great freedom of action. Awareness and integration of the experience of agency in the autobiographical narrative can serve as a basis for the complication and differentiation of the motivational system of the individual and further development of self-determination. Despite the wide representation of leisure studies, the choices made by young adults in leisure activities and attitudes towards them have yet to be explored. To study the manifestations of agency in serious leisure, 24 interviews with informants from the period of growing up were collected. The conducted deductive thematic analysis showed that the manifestations of agency can be found at the stages of initiation, implementation and termination of serious leisure, where they can be presented in the form of initiative, interaction, comprehension of events and decision-making, changes and organization of activities. The analysis of autobiographical narratives shows that the environment of serious leisure is saturated and promising for manifestations of agency at different ages.
Ideas about the Ideal Home in Different Periods of Adulthood: Psychosemantic Approach
Authors: Vasileva Inna V. , Chumakov Mikhail V.
Published: November 2024

The methodological basis of the study is the psychosemantic and thesaurus approaches. Verbalized representations make it possible to objectify the needs, values, and attitudes of the subject in relation to significant phenomena of reality. The results of an empirical study of people’s ideas about the ideal home at different periods of adulthood are discussed. Data were collected using the free association method. To the phrase “ideal home”, respondents gave associations in the format of three verbs, three adjectives, and three nouns. The study involved 286 people, of which 228 people were aged 18–40 years, 47 people were aged 55 years and older. The identification of general semantic categories was carried out by frequency analysis; the comparison of semantic categories between groups of different ages was carried out using the z-criterion. It was shown that comfort, love, happiness, life are common semantic markers of an ideal home for people in different periods of adulthood. Ideas about an ideal home in the age periods studied, along with general features, have pronounced specificity. Depending on age, ideas about an ideal home are specific: for people aged 18–40 years, the most important are the semantic categories of comfort, family and warmth; for people over 55 years old these are the categories of happiness and health. Additional empirical confirmation was received by the proposition that the meaning of a house changes along with a change in a person’s age (S.K. Nartova-Bochaver). Limitations of the study: in the studied sample, people of the first and second periods of adulthood and females predominated. Prospects for the study include expanding age cohorts and balancing the sample by gender.

JUST LIKE THE ONES AROUND HERE: EQUASIMILATIVE CONSTRUCTIONS IN KHWARSHI AND BEYOND
Authors: POLIAKOVA E.E.
Published: November 2024

Equasimilative constructions belong to the semantic field of comparison, but have been studied to a much less extent than comparative constructions. There are practically no areal-typological studies in this area. This paper focuses on equasimilative constructions in Khwarshi proper (Nakh-Dagestanian). Additionally, it provides an overview of equasimilative constructions in the languages of the Caucasus to determine the parameters that influence the marking of these constructions and compares the Khwarshi field data with data from the broader region. Thus, this paper views the Khwarshi equasimilatives in the broader context of Caucasian equasimilatives.

Published: November 2024

One of the most valuable landscapes of the Krylatsky Hills Park are steppe meadows occupying the slopes of ravine-gully systems. In this work, we investigated the problem of the invasive spread of Manchurian walnut (Juglans mandshurica) in Krylatsky Hills Park, especially in areas of steppe meadows. Until the early 2000s, the species was not found in the park. In 2023, we discovered 125 specimens of Manchurian walnut in the park, measured their height and trunk diameter, and plotted the discovered specimens on a map. Most of the plant population is represented by plant undergrowth and young growth. Further intensification of invasion is possible due to the entry of plants into reproductive age, as well as warming and humidization of Moscow climate. Walnut may be one of the transforming species reducing the area of meadows. Among the positive phenomena associated with the spread of Manchurian walnut, the anti-erosion effect of afforestation of steep slopes of gully-beam systems can be considered.

Przedmiot badań: Stosowanie suplementów diety w ciąży może być zasadne, szczególnie w przypadku kobiet, które mają trudności z zapewnieniem pokrycia zapotrzebowania na niezbędne składniki odżywcze poprzez dietę lub dla tych, u których występują specjalne potrzeby żywieniowe, wynikające m.in. z chorób przewlekłych. Indywidualne potrzeby żywieniowe mogą się różnić, dlatego zalecenia dotyczące suplementacji powinny być dobierane indywidualnie dla każdej kobiety w ciąży w zależności od jej sposobu żywienia i stanu zdrowia.
Cel badań: Celem pracy była analiza pokrycia zapotrzebowania na witaminy i składniki mineralne z całodzienną racją pokarmową (CaRP), bez i z uwzględnieniem suplementacji witaminowo – mineralnej, oraz ocena zasadności ich stosowania przez kobiety ciężarne w poszczególnych trymestrach ciąży.
Materiały i metody: W badaniach wzięło udział 46 kobiet w I trymestrze ciąży, 33 kobiety w II trymestrze ciąży i 30 kobiet III trymestrze ciąży, wśród których w każdym z trymestrów ciąży przeprowadzono wywiad żywieniowy 24-godzinny obejmujący 7 kolejnych dni. Oceniono spożycie witamin i składników mineralnych przez badane kobiety ciężarne w kolejnych trymestrach ciąży bez i z uwzględnieniem suplementacji. Skład całodziennych racji pokarmowych badanych kobiet obliczono posługując się programem komputerowym Dieta 6, a uzyskane wyniki porównano z obowiązującymi normami dla poszczególnych trymestrów ciąży. Wyniki zostały opracowane w programie Microsoft Office Excel 2019 oraz poddane analizie statystycznej testem U Manna-Whitneya w programie Statistica v.13.3 firmy StatSoft Polska.
Wyniki: Niezależnie od trymestru ciąży, dieta badanych kobiet ciężarnych bez uwzględnienia suplementacji, nie pokrywała ich zapotrzebowania na witaminę D, foliany oraz żelazo i jod. W odniesieniu do pozostałych witamin i składników mineralnych ich podaż z samą tylko dietą była wystarczająca do pokrycia zapotrzebowania. Zastosowanie suplementacji, w każdym z trymestrów ciąży, z jednej strony pozwoliło na pokrycie zapotrzebowania na foliany i żelazo, natomiast z drugiej strony spowodowało istotnie statystycznie nadmierne spożycie witaminy C, witamin z grupy B, cynku i miedzi w I trymestrze; witamin A, E i C, z grupy B oraz cynku i miedzi w II trymestrze, a także witamin z grupy B, cynku oraz miedzi w III trymestrze ciąży.
Wnioski: Na podstawie analizy uzyskanych wyników można stwierdzić, że występuje zasadność stosowania jedynie suplementów diety zawierających witaminę D, foliany, żelazo oraz jod u kobiet ciężarnych w kolejnych trymestrach ciąży zgodnie z aktualnymi wytycznymi Polskiego Towarzystwa Ginekologów i Położników. Konieczna wydaje się edukacja żywieniowa ciężarnych na każdym etapie ciąży, obejmująca również indywidualny dobór witaminowo-mineralnych suplementów diety w zależności od potrzeb ciężarnej.
Development of a Cloud-Based Road Surface Quality Assessment System
Authors: Quan Lim Ka , Ramli Nor Azuana
Published: November 2024

This research aims to develop a cloud-based system utilizing the You Only Look Once version 8 (YOLOv8) model for assessing road surface quality. The system is designed to address critical road maintenance challenges and the need for high accuracy and fast response road surface quality monitoring. Data acquisition involved images from the Internet, dashcams, and smartphones, with subsequent processing through advanced image techniques. The YOLOv8 model demonstrated efficacy in detecting various road surface defects, achieving a precision of 0.457 and a recall of 0.486. While exhibiting potential in identifying patches and potholes, further refinement is required for crack detection. The model’s processing speed, with 9.7 milliseconds per image, indicates its capability for near real-time analysis. Finally, the model is deployed on cloud infrastructure hosted by Digital Ocean to provide scalability and accessibility. The cloud-based system enables users to upload videos for automated defect detection and offers downloadable results, fostering collaborative initiatives in road surface monitoring. While the model shows promise, particularly in detecting patches and potholes, crack detection has room for improvement. Future work could focus on enhancing the model’s performance for this challenging defect class.

A 23-year-old male military patient from a rural area presented with a persistent cough, significant weight loss, and pruritic, erythematous papules and excoriations on the knee. Microscopic examination of a skin scraping from the knee revealed adult _Phthirus pubis_ and nits. While pubic lice typically infest the pubic area, they can also occur on other body regions, including the eyelashes, axillary area, and scalp. In this case, the patient may have acquired the infection through sexual contact or contaminated bed linens, common in military settings. Additionally, autoinoculation during scratching may have spread the lice to the knee. Healthcare providers should be aware of the potential for _Pthirus pubis_ to migrate to non-perineal hairy locations.
FIFA World Cup 2022 Qatar Corner Kicks: An Analysis on Effectiveness and Match Context
Authors: Clark Alex , Corsie Martin , Gouveia Vitor , Nunes Nuno André
Published: November 2024

This paper presents an in-depth analysis of the tactical and technical attributes of corner kicks during the 2022 World Cup, aiming to elucidate their effectiveness and impact on match outcomes. Sequential analysis was employed to scrutinize a total of 570 corner kicks observed throughout the entirety of the tournament, with subsequent descriptive analysis of the dataset revealing significant findings. Despite a relatively low goal conversion rate (2.6%), corner kicks emerged as pivotal moments in matches, influencing match status in 73.3% of cases. Examination of the area of delivery and first contact identified PA 1/2 as the most effective zone for generating goal attempts and scoring goals, a trend observed across both successful and unsuccessful teams. Notably, direct out-swinging corner kicks exhibited superior efficacy in terms of goal-scoring opportunities. Defensive strategies were also scrutinized, with a mixed zonal dominance approach proving most effective in limiting goals conceded, while a mixed individual dominance structure was optimal for reducing goal attempts, albeit resulting in heightened defensive engagements. Common actions observed during corner kicks included defender interventions and short passes, consistent across both successful and unsuccessful teams. Additionally, analysis of action zones revealed W1/2 and PA1/2 as the most prevalent areas, with successful teams exhibiting a preference for W1/2 and AFGM zones. These findings offer valuable insights for football professionals seeking to refine their tactical and technical strategies, potentially providing a competitive edge in elite-level competition.
Primary Melanoma of the Palatine Tonsil in an Adult Filipino Patient: A Case Report
Authors: Cabatana Katrin Louise , Salud Duane
Published: November 2024

ABSTRACT
Objectives: To discuss a case of primary melanoma of the palatine tonsil in a 57-year-old man presented with a dark, pigmented tonsillar mass initially managed as a case of arterio-venous malformation, and review the literature on its presentation, diagnosis, management and outcomes.
Methods:
            Design: Case Report
            Setting: Tertiary Government Training Hospital
            Patient: One
Results: A 57-year-old man presented with a pigmented, bluish-black mass (7.2 cm) on the right tonsillar area with dysphagia and odynophagia. A CT scan interpretation considered large tonsillar malignancy, right with infiltrations of the soft palate, lingual tonsils and pre-epiglottic space. The initial impression was an arteriovenous malformation and preoperative arterial embolization was followed by a  tonsillectomy. The final biopsy result was mucosal melanoma. Refusing further treatment, he expired nine months later in the emergency room, after presenting with decreasing sensorium and desaturations, jaundice and abdominal distension.
Conclusion: To the best of our knowledge, this is the first reported case of tonsillar melanoma in the Philippines. Primary tonsillar melanoma is rare but its diagnosis is still possible (although it is usually diagnosed in advanced stages). Despite improvement in surgical techniques and adjuvant therapies, its prognosis remains poor. Regular oral cavity screening may help in early detection.
