Forest scientists use regression models widely, particularly for height-diameter modeling. These models offer several benefits for estimating height in homogeneous or non-homogeneous stands. The original models for height estimation based on diameter at breast height have been extended
to include other variables, thanks to technological advancements. The purpose of this article is to provide a literature review using the methodology outlined by Cervo and Bervian (2011), providing helpful information to forest biometricians in selecting a height-diameter model that utilizes
historical data. The models can be classified into four main groups and extended to include other covariates besides diameter at breast height. Many of the models used data transformation but results showed that with the exception of one group (nonlinear models), all other models can be considered
a generalized linear model, with corresponding linear predictors and link functions. The paper also discusses the generation process of these models, the species to which they are commonly applied, and how they can be created using general ordinary differential equations.

Authors: Montiel Torres María Francisca , Teruel Rodríguez Laura
Published: December 2024

Introducción: El auge de la desinformación en los diversos canales de comunicación, especialmente en aquellos soportados por Internet y las redes sociales, ha propiciado que la verificación adquiera un papel crucial. Por ello, los medios de comunicación han reforzado estas tareas y se han generado nuevas iniciativas empresariales y sociales que persiguen dar certeza a la ciudadanía sobre lo que es cierto y es falso en la información que recibe. Muchos estudios académicos estudian este fenómeno preocupante, analizando desde la estructura y contenido de los bulos, hasta las actitudes de quienes los reciben, pero pocos se preguntan cómo son las personas que trabajan en verificación y menos aún dónde están las mujeres en este nuevo entorno laboral. Este trabajo analiza las iniciativas de verificación en los países del Sur de la Unión Europea y especialmente su realidad laboral, cuantificando el peso de las mujeres en ellas y el papel que desempeñan. Metodología: Como base de la investigación se ha utilizado el Censo de iniciativas de verificación elaborado por el Reporters’ Lab de la Duke University para Croacia, Eslovenia, España, Grecia, Italia y Portugal en su actualización de 2023 (N=20); los sitios web de las iniciativas recogidas en el censo y las estadísticas de la Unión Europea, Eurostat. El criterio de selección de la muestra ha sido el país donde se ubican las iniciativas de verificación y la metodología utilizada el análisis de datos mediante técnicas de estadística descriptiva. Se han enriquecido los datos con el seguimiento de las webs analizadas y sus publicaciones durante un año. Resultados: Los resultados muestran que las mujeres representan más de la mitad de la fuerza laboral en las iniciativas analizadas, muy por encima de su peso en la población empleada. También la presencia de mujeres en puestos directivos es, porcentualmente, superior al cuantificado en el total de empresas. Discusión y Conclusiones: Se reflexiona sobre cómo este nuevo espacio laboral está ofreciendo oportunidades para la igualdad para las mujeres en el ámbito del periodismo.
East Wind Breaks: Identification of Zhongguofeng Music as a Form of “Chinese Crossover” and “Hybrid Thinking” in Contemporary Mandopop
Authors: Fan Li , Wei Chow Ow , Fee Lee Yok , Mahamed Mastura , Nie Connie Lim Keh
Published: December 2024

Since 2000, the phenomenal rise of Jay Chou, an iconic pop artist from Taiwan, has evoked discussions on Mandopop scene. This study aims to conduct a micro-analysis of selected music samples from Chou between 2000 and 2010 in order to identify Zhongguofeng music, which employs Phillip Tagg’s music analysis theory. The findings find out that Chou’s musical works demonstrate substantial Chinese elements in terms of lyrics, melody, and music cultural references. In addition, they reflect diversified musical styles, infusing Chinese-style hybridity into popular music. As a result, these musical works have formed a unique Zhongguofeng music standard that could play a defining role in contemporary Mandopop. It is anticipated that a discourse with a specific analytical setting could be established in this study. It can offer an insight into how the framework of hybridity in contemporary Mandopop is used to overcome the borders of genres, geopolitics, narratives, and negotiation of cultural identity between the “local” and the “global.”
Comparison of the primary stability of orthodontic mini-screws manufactured by the Computer Numerically Control and Selective Laser Melting manufacturing methods: An exploratory study
Authors: Yaşar Meriç Öztürk , Irgın Celal
Published: December 2024

Background: This study was to assess the primary stability of orthodontic mini-screws of the same design produced by a conventional and a novel manufacturing method.
Methods: A total of 150 orthodontic mini-screws with a body length of 8 mm, a diameter of 1.6 mm, a button head, and a self-drilling feature were used in the study. Mini-screws were manufactured through computer numerically controlled (CNC) and selective laser melting (SLM) manufacturing methods. Titanium (T) and stainless steel (SS) alloys were used as manufacturing materials. The study was conducted on three groups; CNC-T, SLM-T and SLM-SS. Mini-screws were placed at 60- and 90-degree angles in fresh bovine femur bones, where the cortical bone thickness was 2 mm. With the radiofrequency analysis (RFA) technique, the stability of the mini-screws was determined immediately after they were placed (F0), immediately after applying orthodontic force to the mini-screw (F1), after six hours (F6), and after 24 hours (F24). Three-way robust ANOVA was used to compare the data, and the Bonferroni correction was statistically applied.
Results: Except for the insertion angle of the mini-screw, the group and time factors had statistically significant effects on the RFA values. The highest RFA value was detected in the SLM-T group.
Conclusion: Orthodontic mini-screws manufactured from titanium or stainless steel alloys using the SLM technology can be an alternative to mini-screws manufactured using the traditional manufacturing method. The mini-screws manufactured using the SLM technology demonstrated adequate primary stability when subjected to an orthodontic force.
Keywords: Orthodontic mini-screw, Primary stability, Selective laser melting, Computer numerical control, Radiofrequency analysis
Decolonial Artificial Intelligence; Algorithmic Fairness in Alignment with Turkish and Islamic Values
Authors: Fırıncı Yusuf
Published: December 2024

Research works on topics such as; Fairness in Agreement with European Values: An Interdisciplinary Perspective on AI Regulation or Decolonial AI Alignment: Openness, Viśesa -Dharma and Including Excluded Knowledges, generated the motivation to search for Artificial intelligence (AI) alignment with Turkish and Islamic Values. The driving force to this research work is the fact that all of the algorithmic decision-making systems include bias to some extend and the non-western world needs to construct its own value-based technological and sociological development models since there is not much belief left in the so-called international justice or the so-called democratic values. This research includes examination of brief information about the fundamentals of big data, algorithms, and artificial intelligence. Importance of thick data and digital anthropology is emphasized. Misuse and abuse AI has been identified as one of the most important challenges. Vygotsky’s arguments on social learning, social construction of technology theory and worldview theory may provide some of the arguments to construct the idea of an AI approach may be developed in accordance with Turkish and Islamic values. Decolonial AI arguments and fairness in AI approaches have also been utilized to empower our argument. Lastly, brief information on Turkish and Islamic values were presented, limited to the scope of this research.

Досліджено біосинтез стероїдних сполук селекціонованим ґрунтовим стрептоміцетом Streptomyces avermi- tilis УКМ Ас-2179 (54) за різних умов глибинного культивування і визначено їхній вміст у біопрепаратах, розроблених на основі метаболітів цього штаму. Для аналізу дериватів стеролів, екстрагованих з біомаси, супернатантів культуральних рідин та біопрепаратів застосовано метод газової хромато-масспектроме- трії. У біомасі досліджуваного стрептоміцету стероли виявлено в значно більших кількостях, ніж у супер- натантів культуральних рідин, а їх спектр і співвідношення були різними. Попередник стеролів сквален виявлено в біомасі продуцента в кількості 276,3 мкг/г за умов вирощування на синтетичному середовищі і 119,4 мкг/г на органічному. У біомасі S. аvermitilis УКМ Ас-2179 (54) переважав 24-епібрасинолід, вміст якого сягав 378,1 мкг/г на органічному середовищі і 448,5 мкг/г на синтетичному. S. avermitilis не синтезував ситос- терол і стигмастерол, що важливо з огляду на нематицидні властивості штаму. У складі метаболітних біопрепаратів найбільший загальний вміст стеролів (22,8 мг/л) виявлено в удосконаленому аверкомі. Екзо- генні стероли мікробного походження відіграють важливу роль у регулюванні їхнього співвідношення в рос- линах і сприяють підвищенню резистентності до фітопатогенів та фітонематод. Селекція стрептоміце- тів, здатних синтезувати не лише підвищений вміст цільового продукту, а й стероли, а також створення метаболітних біопрепаратів на їх основі є перспективним напрямом у мікробній біотехнології.

The paper discusses the possibility of realizing a superconducting state at temperatures of ≈102 K in layered nano-sized heterostructures – thin-film objects consisting of alternating layers of metals and semimetals (or semiconductors) with a thickness of (1–102) nm. The numerical estimates show that in such structures, an increase in the electron density in semimetals (semiconductors) leads to a change in the electrical conductivity up to the appearance of superconductivity. If we assume that superconductivity is realized as a result of electron-phonon interaction, causing the formation of Cooper electron pairs (Bardeen–Cooper–Schrieffer mechanism), then an increase in the electron density in the semiconductor layer of a nano-sized heterostructure should cause an increase in the pairing constant and so-called high-temperature superconductivity can be realized.

The study deals with synthesis, structure and optical properties of the phosphate glasses of the composition (1-x) *(44.37P2O5 - 8.32MoO3 -2.94Bi2O3 - 44.37K2O) - xEuPO4 (where x = 0, 0.5, 1.0, 2.0, and 5.0 mol. %). The structure, morphology, and optical properties of the glasses have been observed and analyzed with the use of the XRD, SEM, light diffuse reflection, and luminescent methods. It was found that the glasses doped with EuPO4 crystalline particles reveal intensive photoluminescence mainly caused by the 5D0->7FJ (J = 1 – 4) radiation transitions in the Eu3+ ions. Molybdenum (VI) and bismuth (III) oxides modify a vitreous network and can provide wide light absorption bands in the spectral range ~300 – 430 nm and low intensity luminescence bands in the range 300 – 525 nm, too. Based on a comparison of the spectral characteristics of the radiation of Eu3+ ions luminescence in EuPO4 crystals and manufactured glasses, it was assumed that the initial EuPO4 particles do not dissolve completely under melting and are present in the manufactured glasses as nanoparticles of small (several nanometers) size. The obtained results indicates that the glasses under study can be used for elaboration of “warm light” emitting devices.

The work is devoted to the investigation of the long-term resorption of BHA/magnetite/chitosan composites with a magnetite content of 1, 5, 25, and 50 wt.% in physiological solution for different periods of time (2, 10, 16, and 31 days) and their adsorption activity toward methylene blue. It was shown that the content of magnetite significantly affects the rate of resorption of materials, in particular at the initial stages; the highest rate of resorption is observed during the first 2 days. In the next 8-10 days, a sharp decrease in the rate of resorption of all composites is observed, followed by stabilization on the 15th day of the in vitro experiment. At the same time, the most significant weight loss of test samples occurs when added more than 5 wt. % of magnetite. The dynamics of the dissolution process is also confirmed by the presence of Ca, P and Fe in physiological solution, a change in the pH of the saline, a decrease in the size and smoothing of composite particles, and an increase in the specific surface area. The adsorption activity for methylene blue increases with increasing amounts of chitosan and magnetite in the composites up to 168 mg/g for 25% magnetite (2.5% chitosan) compared to 108 mg/g for pure BHA. The obtained results confirmed the controlled resorption and high adsorption properties of BHA/magnetite/chitosan composites, which provides prospects for their medical application.

Barium titanate is an important ceramic material in piezoelectric devices. Barium titanate (BT) was prepared via a hydrothermal process at 200 °C for 24 hours. This study initially focused on characterizing barium titanate nanoparticles (BaTiO3) by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) was used to determine the crystalline structure of the material and the functional groups present in the sample. Additionally, the structure and composition of BaTiO3 were confirmed using an energy dispersive spectroscopy (EDS). A disk of barium titanite was made and sintered at a temperature of 1000°C for 4 hours. To simulate the material to confirm its piezoelectric properties, the density was measured and impedance spectra were studied to determine the relative and absolute permittivity; this data was then entered into APDL ANSYS program. The complexity of the resonant modes present in the material causes a piezoelectric response with multiple peaks over a wide frequency range. These peaks can be used to study situations where a specific frequency response of the material is required.

The paper investigates the influence of the content of Al-Ni alloy quenched from the molten state on the abrasive wear rate of ultra-high-molecular-weight polyethylene on rigidly attached abrasive particles. Studies have shown that the addition of 5–30 mass% of the quenched aluminum alloy to ultra-high-molecular-weight polyethylene reduces the rate of abrasive wear by ~50%. The improvement of this indicator is due to the high values of microhardness, dislocations density, and microstresses of rapidly quenched Al-Ni alloys.

This work develops a numerical model for analyzing the growth conditions of Cd0.9Zn0.1Te crystals by the traveling heater method (THM) in a multi-zone electrodynamics gradient (EDG) furnace. The main focus is on determining the temperature profile and the thickness of the Te-rich solution to improve the structural homogeneity of the crystals and minimize defects. The work also proposes a dimensionless criterion based on the ratio of the thermal Rayleigh number (RaT) to the concentration Rayleigh number (RaC), which allows for evaluating the growth conditions. The calculations performed make it possible to determine the main technological parameters that ensure a nearly flat crystallization interface. The adequacy of the calculated thermal conditions was confirmed experimentally. The obtained samples showed characteristics suitable for manufacturing spectroscopic grade detectors.

Based on the determined values of density, dynamic viscosity and molar volumes, the thermodynamic activation parameters and excess thermodynamic activation parameters of viscous flow at temperatures from 293.15 K (20°C) to 313.15 K (40°C) were calculated for the mixed binary solvents water – propylene glycol (PG). Using the isotherms at 298.15 K, assumptions were made about the composition regions of binary solvents with different structural organizations. The structure of the mixed solvent has an impact on the various functional characteristics of the systems water – PG, and it could also influence the performance of medicinal products with a liquid dispersion medium. The density and excess density, as well as the dynamic viscosity and excess dynamic viscosity for systems water – PG were determined as a function of the PG concentration. Using the method of spin probes, it was demonstrated that changes in the dynamic viscosity of systems water – PG correlated with the alterations in the viscosity of the microenvironment of spin probe molecules. The viscosity of the microenvironment was also influenced by the interaction between molecules of dissolved spin probes and solvent molecules.

The MOFs, copper–1,3,5- benzenetricarboxylate (Cu-BTC) samples were synthesized by immersing self-assembled films in solutions of copper nitrate and trimesic acid through a biomimetic mineralization method. During the synthesis, self-assembled monolayers with different end groups acted as templates, facilitating the nucleation and growth of Cu-BTC crystals. The resulting products were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer-Emmett-Teller (BET) analysis. The influence of the synthesized materials on the adsorption performance of methylene blue (MB) dye was systematically investigated. The results show that the Cu-BTC compound microspheres, induced by sulfonic acid groups, have a uniform morphology and exhibit effective adsorption of MB dye. The theoretical maximum adsorption capacity of these microspheres for MB dye is 75.6 mg·g–1. The adsorption data from this process are consistent with both the pseudo-first-order kinetic model and the Langmuir isotherm model. After four adsorption-regeneration cycles, the microspheres retained a high adsorption efficiency for MB dye.

The process of revising the KPK law gave rise to a new structure within the corruption erradiction commision. With the existence of the KPK Supervisory Board, the KPK's performance must be adapted to the results of the revision of the law. This article aims to explain cases of licensing issues experienced by KPK employees or investigators in an effort to wiretap corruption suspects to the KPK Supervisory Board. This arose due to the revision of the latest KPK law, namely Law number. 19 of 2019 so that there are many bureaucracies that hinder the performance of investigators in carry out efforts to eradicate corruption. The performance of investigators who are required to be fast and immediately confronted with layers of bureaucracy related to wiretapping. The research method used is a normative juridical approach  using the statutory approach. The results of the research obtained are that the latest revision of the KPK law makes the wiretapping mechanism for corruption suspects must take permits and layers of bureaucracy. After a judicial review related to Law Number 19 of 2019, the Constitutional Court granted a material claim related to the article governing wiretapping. Now the KPK only notifies the Supervisory Board no later than 14 (fourteen) work days after the wiretapping is carried out. This is a good thing because the investigator's actions are impermeable and immediately can run well.
On the prospects of identifying rare and rare earth metals in the black shale sequence of the Eastern segment of the Greater Caucasus

Published: December 2024

The expansion, updating, and comprehensive utilization of the mineral resource base for rare and rare-earth metals necessitate the search for and development of new deposits of non-traditional genetic types, including those localized within black shale formations. This study examines the distribution of rare and rare-earth elements (REE) in the black shale formation of the Eastern segment of the Greater Caucasus, where extensive research and exploratory drilling have led to the discovery of several deposits and occurrences of non-ferrous metals. The results of geochemical and mineralogical investigations reveal a high concentration of rare and rare-earth elements (REE) and other metals within the black shale formation. All lithological types of rocks constituting the black shale formation, as well as rocks from the near-deformation and hydrothermally metasomatized zones, were tested for this study. Comparative studies of the behavior of rare and rare-earth elements across various rock types indicated significant variations in their elemental spectrum and concentrations. Notably, elevated concentrations of rare-earth elements were observed in clay-rich rocks, attributed to the sorptive capacity of clay minerals. Analysis of the distribution of microelements in the rocks and main minerals of the black shale formation highlighted a considerable presence of rare, rare-earth, and other elements, with concentrations exceeding their Clarke values by several times. Distinct anomalous zones were identified for Au, Mo, Cs, La, Ce, Nd, Sm, and U, while anomalous zones were noted for Cd, Se, Hf, Yb, Lu, Eu, Tb, and Th. The geochemical characteristics related to the concentration of these elements were also determined. The findings indicate that the unique properties of graphitized clay shales and accessory minerals within the formation significantly influence the processes of concentration of rare and rare-earth elements, serving as sources of associated metals. This study further analyzes the geochemical and mineralogical characteristics of the black shale formation and delineates zones of mobilization and concentration for rare, rare-earth, and other elements.
Study on the genesis of deposits of the Productive Series of the Bibi-Heybat field by using a complex of borehole data

Published: December 2024

The majority of developed oil and gas fields in our country are associated with deposits of terrigenous origin. The results of the research carried out provide a basis to conclude that terrigenous reservoirs are not completely homogeneous. Generally, the individual layers differ in their composi’tion in terms of porosity, permeability, shape, size, etc. Therefore, the heterogeneous characteristics of reservoirs should be determined in advance. For this reason, the study of sedimentation conditions of terrigenous layers and the genesis of deposits can be useful for geologists and geophysicists when discovering new fields. This article examines the issue of studying the genesis of deposits of the Productive Series based on the results of quantitative interpretation of borehole data. Sections of wells NoNo X1, X2, X3, X4 from horizons X, XI, XII, XIII, XIV, and XV of the Productive Series (PS) were conditionally chosen as the area of research in the Bibi-Heybat field. The values of effective porosity and volumetric clay content were calculated using established methods and formulas for selected well sections, and histograms of the variation of these values with depth were plotted. The genesis of deposits was studied on the basis of histograms, and facies of stream, bar, and beach-plain origin were identified. The article also defines intervals for the identification of stream, bar, and beach-plain facies in the studied areas and presents 2D and 3D models characterizing the distribution of their thicknesses in the studied region. The research work also involved building 3D models of the distribution of determined facies thicknesses as well as effective porosity, volumetric clay content, and oil and gas saturation across the wells. According to the 3D model analyses, the permeability coefficient value for the study area ranges from 0-120 mD, the porosity value ranges from 0-20%, and the oil and gas saturation ratio value ranges from 0-100%.

This study presents a detailed seismic attribute – mainly Root Mean Square (RMS) amplitude and Sweetness attribute analysis, aiming to improve the understanding of subsurface structures. We apply both these seismic attributes on a specific petroleum field called Lokbatan-Puta-Gushkhana. Additionally, the study investigates the use of RMS amplitude analysis in the characterization of reservoirs, focusing on the estimation of fluid volume and porosity. The results offer useful guidance for reservoir management techniques and aid in the optimization of reservoir modeling. Seismic attributes listed above (RMS Amplitude, Sweetness) make it possible to distinguish zones by variable properties of the wave field. If we observe that the calculated seismic attributes differ significantly, then it can be assumed that the elastic properties of this area (velocity, density, etc.) have also changed. Differentiation of elastic properties and, accordingly, facies compositions allows for predicting the distribution of reservoirs. The outcomes of this study have a wide range of implications for the petroleum industry and provide a solid methodology for using RMS amplitude analysis in reservoir characterization and basin-scale exploration. The insights derived from this study can help with decision-making in the oil and gas exploration industry, enhancing resource evaluation and promote the development of sustainable energy sources. In order to study the distribution of reservoirs in the Lokbatan-Puta-Gushkhana area of the Absheron oil and gas region in the Productive Series (PS) and the underlying sediments (Diatom and Maykop), the results of the complex studies conducted according to the geophysical survey of the wells and 2D seismic data were analyzed. Additionally, we combine RMS attribute analysis with geological interpretations to improve reservoir models and drilling strategies. Our findings not only contribute to the understanding of the geological complexities of the Lokbatan-Puta-Gushkhana field but also offer practical insights for hydrocarbon exploration and production in this prolific region.

The article substantiates the cause-and-effect relationship between the emergence of military conflicts and society’s orientation towards consumer values and the ruthless depletion of natural resources for profit, which leads to a significant deterioration in the environmental situation worldwide. Natural resources, favorable climatic conditions, geographical advantages, and a developed industrial base are all key factors contributing to wars, which in today’s globalized society take on hybrid forms, making it difficult to hold parties accountable for environmental crimes. Accordingly, the issue of environmental responsibility of belligerent states for crimes committed against nature is relevant and needs to be addressed both at the international and national levels. The purpose of the article is to study the phenomenon of environmental responsibility at two levels – philosophical and legal. The philosophical aspect allows for the identification of the moral and ethical factors influencing human disengagement from ecological awareness. The legal aspect examines the problem of the effectiveness of the principles and norms of international and national environmental law in wartime. Having conducted an interdisciplinary analysis of environmental responsibility from both philosophical and legal perspectives, we identified the mental causes of environmental problems, specifically those that clearly reveal the way of thinking and core values of contemporary society, and also clarified the existing problems and prospects in international law regarding individual and national liability for crimes against nature. The originality of the study lies in the fact that, firstly, the problem of environmental responsibility is considered in direct relation to the social, ethical, and legal factors shaping modern society; secondly, we have substantiated the need to develop a Fifth Geneva Convention for the protection of the environment during armed conflict and made proposals regarding its content; thirdly, the authors’ methodology for assessing the environmental responsibility of countries is presented based on data from authoritative international indices. The methodology includes criteria for environmental responsibility (achievement of sustainable development goals, environmental efficiency, rule of law, social progress) and the calculation of the index for five countries involved in armed conflicts. The results obtained demonstrate that wars, especially long ones, not only destroy ecological systems but also reduce the level of environmental responsibility involved countries and lead to a general decline in ecological awareness.

Published: December 2024

As a result of the study of core material in the volume of 211 thin sections from five boreholes of the Northern part of the Lviv Paleozoic Trough, a complex of fossil green, red, and charophyte algae was revealed, which consists of 20 species of 13 genera of green, red, and charophyte algae, among which five species of five genera are identified for the first time for the Devonian deposits of the Lviv Paleozoic Trough. The carbonate deposits belong to the Frasnian and Famennian stages and are represented mainly by sandstones, argillites, siltstones, limestones, dolomites, marls, and white chalk. Carbonate deposits are represented mainly by pelitomorphic wackestones, packstones, wackestone-packstones, grainstones, grainstone-packstones, micrite, bioclastic wackestones, and microbioclastic pelitomorphic wackestones. Limestones often have a pelitomorphic texture, enriched with sand material or dolomitized. The algae are confined primarily to pelitomorphic wackestones of the Waulsortian type, which indicates the intermediate facies of the shelf margins, which were formed by the open circulation of sea waters. To a lesser extent, algae occur in packstones, grainstones, wack-packstones, and are found predominantly along the remains of foraminifera, crinoids, bryozoans, ostracods, and sponge spicules. It is revealed that the algal assemblage of the Famennian stage is depleted and represented mainly by the green tubular algae of the families Palaeoberesellaceae Mamet et Roux and Dasycladaceae Kützing. Higher up the section, a few charophyte algae of the genus Planoumbella Platonov are found. The assemblage of the Famennian stage is significantly enriched, both numerous and systematic. Numerous charophyte and red algae appear, especially in the upper part of the section, which corresponds to the stratigraphic level of the zone C1ta of Donbass. These deposits were considered for a long time to be Tournaisian until at the All-Union Congress in 1986 the Devonian-Carboniferous boundary at the base of the Gattendorfia (Acutimoceras) goniatite zone and the Siphonodella sulcata conodont zone was drawn, which represents the top of the C1ta zone of Donbass. At this level, the richest and most varied algae assemblage is revealed. Above this level, representatives of the genus Parachaetetes Deninger and charophyte algae are not found. The prevalence of the green siphoncladal algae in the Frasnian association indicates a calm hydrodynamic regime below the level of the tide, as well as the depth of the basin, which does not exceed 3-5 m, slight fluctuation in the depth of the sea basin, good illumination, and warm water. The significant distribution of charophyte algae in the Famennian time indicates a decrease in salinity in the paleobasin due to the flow of fresh water from the Kovel uplift.

A series of novel iridium(III) complexes containing 5-N-(aryl)-amino- or 5-cycloamino-3-(pyridine-2-yl)-1,2,4-triazine ligands was obtained. These complexes exhibited red luminescence in solution as well as in the solid state.  Based on the DFT studies it was suggested that N(2) atom of the 1,2,4-triazine core is preferable to N(4) one as the coordination site in the complexes of Ir(III).
Assessment of Pm41 gene frequency in Turkish bread wheat germplasm
Authors: Mustafa Zemran
Published: December 2024

Powdery mildew, caused by Blumeria graminis f. sp. tritici, poses a high risk to worldwide wheat production, resulting in severe yield reductions. Resistance breeding provides a sustainable approach to managing this disease, with the Pm41 gene being pivotal in providing all-stage resistance. This research examined 96 cultivars of Turkish bread wheat (Triticum aestivum) from several Turkish research institutions for the Pm41 gene. PCR analysis indicated that 57% of the studied cultivars possessed the Pm41 gene. The highest detection rate of 89% was recorded in cultivars from Bahri Dağdaş International Agricultural Research Institute Directorate/Konya, whereas Field Crops Research Institute Directorate/Ankara exhibited a lesser frequency of 29%. The data demonstrate regional disparities in Pm41 presence. The observed Pm41 gene in over half of the cultivars suggests that Turkish wheat cultivars possess gene variants that might be important for resistance. This work underscores the significance of preserving genetic materials for finding novel variants of the resistance genes, which are essential for sustainable wheat cultivation and food security.

Regmatogenic retinal detachment is one of the severe conditions in ophthalmology that, in the absence of timely treatment, leads to disability among the population. The purpose – to analyze the prevalence of regmatogenic retinal detachment in the Astrakhan region over the past five years (2019–2023). Indicators such as morbidity, follow-up, and disability due to this pathology were evaluated. The study analyzed two groups of patients (1,411 individuals): the adult (1,345) and child (66) populations. All patients underwent a standard ophthalmological examination. According to the study, the incidence of regmatogenic retinal detachment in the Astrakhan region significantly exceeded the aver-age for Russia and amounted to 148.4 per 100,000 population. In both groups, the incidence rate in 2020 increased compared to 2019 and remained stable until 2022 inclusive; however, in 2023 it decreased by 15.6 % (adult popula-tion) and 33.3 % (child population). Conclusion. Timely treatment of regmatogenic retinal detachment requires a com-prehensive approach that includes both prompt care and preventive measures among the population.

Sporcuların hem spor hem de eğitim yaşantılarını verimli bir şekilde yürütebilmelerine yönelik araştırmalar ve uygulamalar son yıllarda artmıştır. Bu nedenle sporcuların çift kariyer yetkinliklerinin ayrıntılı olarak incelenmesi, mevcut durumun ortaya koyularak gerekli önlemlerin alınması açısından önemlidir. Bu doğrultuda, araştırmanın amacı sporcuların çift kariyer yetkinliklerinin belirlenmesi ve çift kariyer yetkinliğinin demografik özellikler açısından incelenmesidir. Araştırmaya 151 kadın (yaş ort:19,38±2,33) ve 283 erkek (yaş ort:17,90±2,94) olmak üzere toplam 434 sporcu (yaş ort:18,64±2,65) katılmıştır. Verilerin elde edilmesi amacıyla araştırmacılar tarafından hazırlanan kişisel bilgi formu ile Sporcular için Çift Kariyer Yetkinliği Ölçeği kullanılmıştır. Veriler tanımlayıcı istatistikler, bağımsız gruplar testi ve tek yönlü varyans analizi (ANOVA) ile analiz edilmiştir. Elde edilen bulgulara göre sporcuların çift kariyer yetkinliklerine sahip olma algılarının ve çift kariyer yetkinliğine verdikleri önemin cinsiyet, yaş, eğitim düzeyi ve spor türü değişkenlerine göre anlamlı düzeyde farklılık göstermediği belirlenmiştir. Akademik başarı ve spor deneyimine göre ise algılanan yetkinlik ve algılanan önemin alt boyutlarında anlamlı farklılıklar olduğu belirlenmiştir. Genel olarak, akademik başarısı ve spor deneyimi daha yüksek sporcuların çift kariyer yetkinliklerine sahip olma algılarının ve çift kariyer yetkinliğine verdikleri önemin daha yüksek olduğu sonucuna varılabilir. Antrenörler, spor psikologları ve yöneticiler sporcuların çift kariyer yetkinliklerine yönelik bulguları dikkate alarak çeşitli uygulamalar planlayabilir ve sporcuları bu alanda geliştirebilirler.
