Authors: Lokmanoğlu Ensar , Bora Özlem
Published: December 2024

In today's age of digital transformation, transferring information and documents from physical environments to digital domains aims to effectively reach wider audiences, increase business volume, and ensure sustainability. In tracking alternative dispute resolution methods, which affect citizens, judicial personnel, and all elements of the justice system, it is crucial to align the existing structure with economic, cultural, and legal systems through institutional digitalisation strategies and innovative approaches, dependent on developments in information technologies. Given traditional judicial processes' slowness, inefficiency, and high costs, the need to restructure the digitalisation processes associated with alternative dispute resolution methods is undeniable. This study will examine the digitalisation process and the necessity of revising the existing judicial system in line with technological developments, specifically within alternative dispute resolution methods. By leveraging the innovations, developments, and transformations brought by the digital age, new approaches to digital transformation have been developed, with an e-government infrastructure designed to appeal to all segments of society, aiming to make alternative dispute resolution methods more accessible and efficient in both social and individual contexts, adapting to the changes brought by advances in information technology. Our study consists of an introduction followed by three main sections. The first section discusses digitalisation in general; the second focuses on the concept of e-government and the development of the e-government system; and the third examines digital approaches in alternative dispute resolution methods, particularly in digital arbitration, digital mediation, and digital conciliation. The study concludes with a section presenting the opinions and recommendations we have reached based on our national and international literature research, focusing on practical issues.
The role of social quality in enhancing total quality management: An assessment through corporate social responsibility and business ethics
Authors: Aktürk Esin Benhür
Published: December 2024

This study explores the role of Corporate Social Responsibility (CSR) and Business Ethics (BE) in enhancing Social Quality (SQ) within the framework of Total Quality Management (TQM). The primary objective is to analyse how CSR and BE contribute to the development of SQ, focusing on the interconnectedness of these concepts and their practical implications for business performance. A qualitative research design was employed, utilising a content analysis approach to systematically examine data from corporate reports, academic literature, and case studies. The findings reveal that CSR and BE are critical in fostering SQ by promoting brand reputation, stakeholder trust, employee engagement, and operational efficiency. Furthermore, companies that align their strategies with international standards such as ISO 26000, SA8000, and SEDEX achieve higher levels of SQ and sustainability. This study contributes to the existing literature by presenting a holistic framework that links CSR, BE, and SQ, offering theoretical and practical insights for businesses, policymakers, and researchers. The implications of this study highlight the necessity for companies to integrate CSR and BE into their TQM practices to achieve sustainable development and long-term value creation.

Under the lens of ads: Digital surveillance and pre-roll advertising avoidance dynamics
Authors: Sağlam Munise Hayrun , Kırcova İbrahim
Published: December 2024

Programmatic advertising operates within a surveillance framework that monitors consumer behaviour and generates personalised content to deliver more targeted advertisements to audiences. While this framework analyses large-scale data from users and has the potential to enhance the relevance of advertisements, it can also negatively impact the user experience. This study examines the factors influencing avoidance behaviours towards pre-roll video advertisements by analysing the relationships between perceived marketing surveillance, ad clutter, skippable ad irritation, and perceived autonomy. For this purpose, data collected from 547 participants were analysed using structural equation modelling (SEM). The study's findings show that increasing the relevance of advertisements mitigates surveillance-induced negative attitudes and reduces viewers' tendency to avoid skippable ads. The results underscore the importance of granting viewers greater autonomy to improve the user experience and minimise ad avoidance. Furthermore, the study highlights the necessity of developing more balanced and ethical advertising strategies that enhance consumers' sense of control and alleviate the intrusive effects of programmatic advertising's surveillance nature.
Assessing the impact of interest rate fluctuations on sector index volatility in Bourse Istanbul: A GARCH approach
Authors: Toğuç Nurhan
Published: December 2024

This study analyses the impact of interest rate changes and past volatility on sector index returns in Borsa Istanbul using a GARCH(1,1) model. The results show that interest rate changes negatively affect sector returns, including banking, food, holdings, tourism, services, transportation, financial, industrial, and technology. Furthermore, the GARCH(1,1) model indicates persistence in volatility in sectors like banking, holdings, transportation, financial, industrial, and technology, where past volatility strongly influences future volatility. Conversely, sectors such as food, tourism, and services exhibit less volatility persistence, suggesting more stable returns during interest rate fluctuations. The GARCH (1,1) specification outperforms the ARCH model by capturing the persistence of variance, making it a more reliable measure for sectoral volatility. The results align with previous research, mainly on the sensitivity of financial sectors to interest rate changes and market volatility. This study's unique contribution lies in its focus on BIST 100 sectors, offering valuable insights for investors to optimise asset allocation. By understanding sector-specific sensitivities to interest rate changes and volatility, investors can make informed decisions to enhance returns.

ULUSLARARASI HUKUK PERSPEKTİFİNDEN TANINMAYAN DEVLETLERİN DURUMUNA BAKIŞ: SOMALİLAND CUMHURİYETİ ÖRNEĞİ
Authors: Erdal Selcen , Bayrak Gülizar Feyza
Published: December 2024

Tanıma işlemine konu oluşturan en önemli unsur “devlet”tir. Devletin tanınması işlemi, bir bakıma uluslararası toplumu şekillendirmekte ve oldukça önemli hukuki etkiler yaratmaktadır. Bunun yanında, tanınmanın devletin oluşumunu sağlayan unsurlar arasında yer almadığı da genel olarak kabul edilmektedir. Böylelikle, bir devletin tanınmamış olması, onun fiilen var olma gerçeğini değiştirmemekte ve hesaba katılma zorunluluğunu beraberinde getirmektedir. Buna rağmen, fiilen var olan ve fakat tanınmayan devlet, uluslararası alanda önemli güçlüklerle karşılaşmakta; tanınmama, adeta uluslararası sistemin dışına itilmiş bu yeni devleti, yoksulluğa ve geri kalmışlığa mahkûm etmektedir. “Somaliland Cumhuriyeti”, mevcut hiçbir devlet tarafından tanınmamış olmasıyla, bu tespiti doğrulamaya hizmet eden oldukça özel ve önemli bir örnek olarak ortaya çıkmaktadır.
Ceza Muhakemesinde Düşme Kararlarının Suçsuzluk Karinesine Etkisi
Authors: Boga Bekir
Published: December 2024

Ceza muhakemesinde bir suçun ispatı, hâkimin veya mahkemenin her türlü şüpheden arınmış kanaatini gerektirmektedir. Böyle bir kanaat hasıl olmadıkça sanık hakkında mahkûmiyet hükmü verilebilmesi mümkün değildir. Diğer taraftan mahkûmiyet hükmü olmadığı müddetçe sanığın suçlu olarak kabul edilmesi de yasaktır. Avrupa İnsan Hakları Sözleşmesinin 6. maddesinin 2. fırkasında açıkça belirtilen bu kural Türk Hukukunda genellikle masumiyet karinesi olarak isimlendirilmektedir. Ceza muhakemesinde mahkeme bazı hallerde sanık hakkındaki suç şüphesi ile ilgili bir karara varmamakta, sanığın ne suçlu ne de suçsuz olduğuna ilişkin bir kanaat paylaşmamaktadır. Bu çalışmada masumiyet karinesi ile ilgili iki farklı sorun ele alınmaktadır. Birinci olarak ceza mahkemesinin suç şüphesine ilişkin olumlu veya olumsuz bir kanaate varamadığı durumlarda yargılama konusu olay ile ilgili diğer hukuk disiplinleri sanığın sorumluluğunu kabul edebilecek midir? İkinci olarak ise sanığın ceza mahkemesinden üzerindeki suç şüphesinin tamamen kaldırılmasını isteme hakkı bulunmakta mıdır?

Authors: Колядюк А.С.
Published: December 2024

Дослідження оболонок складної форми, особливо для комбінованих сферичних і циліндричних оболонок, останнім часом стали важливим та актуальним завданням. Крім того, проблеми з коливаннями неминуче виникають внаслідок дії на такі комбіновані оболонкові конструкції експлуатаційних навантажень. Варто зауважити, що однією з головних проблем таких досліджень є визначення коректних навантажень на складні оболонкові конструкції під дією швидкоплинних ударних навантажень. При цьому якість кінцевого результату залежить від коректного вирішення обох задач, які фактично належать до двох різних напрямів: обчислювальної гідродинаміки та обчислювальної динаміки твердого тіла. У статті розглянуто взаємодію ударної хвилі з крутим фронтом і стрибком тиску ΔP = 1 × 106 зі сферично-циліндричною комбінованою оболонкою типу циліндр — півсфера (радіус циліндричної та сферичної частин 324 мм). Цей клас досліджень виконано із застосуванням підходів до вирішення суміжних проблем механіки твердого тіла та обчислювальної динаміки рідини. Отримано значення параметрів тиску (у вигляді дифракційного тиску) під час набігання ударної хвилі на складну оболонку. Проаналізовано коливальні процеси складної оболонки під дією динамічного навантаження.

Досліджується траєкторія похилої тріщини в плоскому елементі конструкції з використанням неявної схеми, оптимізованої для досягнення точності в аналізі змішаного режиму руйнування. Розроблена схема забезпечує точне виконання умови рівності нулю коефіцієнта інтенсивності зсувних напружень (КІН) на кожному кроці алгоритму, що дозволяє точно відслідковувати напрямок розвитку тріщини. Розроблено адаптивний алгоритм для генерації регулярної сітки в межах кругової зони, що оточує вершину тріщини, змодельованої кусково-лінійною кривою. Такий підхід до створення сітки дозволяє покращити точність обчислення КІН, що підтверджується шляхом порівняння з відомими з літератури розв’язками для руйнування нормальним відривом. Крім того, проаналізовано залежність зсувного КІН від кута повороту другого сегмента тріщини в умовах критичного стану. Результат аналізу дозволив спростити алгоритм неявної схеми. Для подальшої перевірки було проведено паралельне дослідження з використанням нерегулярної сітки, згенерованої вбудованими функціями MATLAB, що продемонструвало порівнянну точність у визначенні КІН для різних типів сітки. Проілюстровано розраховану траєкторію тріщини та розподіл поля напружень фон Мізеса навколо її вершини, що надає змогу скласти повне уявлення про поведінку напружень та вплив уточнення сітки на прогнозування траєкторії.

Some experiments with biological membranes have shown that a number of dopants can induce spontaneous lateral lipid separation into domains with different physical properties even in a monolipid membrane. Since most such dopants are approved drug substances, one can suppose this phenomenon is relevant to their therapeutic action. Such effect was observed for the dopants with bimodal adsorption. We assumed that the underlying mechanism of such dopant-induced domain formation is preferential dopant binding ‘like the surroundings′ rather than ‘unlike the surroundings′. In the present work, the simulation method based on the mechanism of preferential dopant binding to monolipid membrane has been developed. The domains sizes were calculated using a simple procedure similar to that used for percolation clusters. Using the method, the mean size of the largest lipid domains was shown to grow by orders of magnitude under moderate increase in the extent of preferential dopant binding. This finding affirms preferential binding as a governing mechanism of lipid domain formation in the systems explored. Adsorption isotherms for the case of bimodal sorption, albeit irrespective of surrounding, were analytically obtained. They coincide with the corresponding numerical simulation results. The method can be easily modified for exploring any systems with polymodal binding to a network of connected sites, so it may see increased application in the future for various physical, chemical, biological, biophysical and other systems.

A new method for creating an absorber for a sampling detector using 3D printing technology on an FDM printer is proposed. A prototype of the absorber was manufactured using the proposed method. Alloys of bismuth, lead, tin and cadmium are proposed as absorber materials. The alloys studied are close to lead in their absorption properties; at the same time, they have a melting point that allows their use in 3D printing together with polymeric materials, avoiding high temperatures. It is experimentally shown that the selected material and method can potentially be used to form an alternating scintillator-reflector-absorber structure in a single technological cycle. The proposed method can be useful in the development of sampling detectors with improved energy resolution.

Deep eutectic solvents are increasingly being used as extraction media as their properties are easily tunable and they can fulfill the green chemistry criteria. In this study, a range of hydrophobic (deep) eutectic solvents was developed as potential extractants of elemental impurities. The experimental results provided insights into the solid-liquid equilibrium of the binary mixtures containing menthol with various organic compounds. The NMR and FTIR spectroscopy were applied to characterize the eutectic compositions. The extraction property towards elemental species was evaluated in the terms of distribution coefficient for 24 elements. It has been shown that the inclusion of a chelating reagent as сompnent of the eutectic solvent can significantly increase the group extraction efficiency of metal ions.
The effect of deflation on land cover in arid conditions and measures of fighting against it (on the example of the Caspian coastal region of the Republic of Azerbaijan)
Authors: Guliyev İsmail A. , Mardanov İlham İ.
Published: December 2024

The article is dedicated to the problem of degradation as a result of the soil deflation on the arid plain of the Caspian coast. The Caspian coast environs the Siyazan-Sumgait massif and the Boghaz plain. The Siyazan-Sumgait massif and the Boghaz plain take second place in the Caspian coastal plains for aridity after the South-Eastern Shirvan plain. The places of the semi-stationary observation pitches were selected for location of the experiments in the research region. While selecting the pitches, the degree of vegetation of the area, the distance from the sand coast, the micro and nano relief forms as a result of wind, level of anthro-pogenic loading of the zone were taken into account. The investigation of the problem was based on the results of field and laboratorial analysis in 2017-2019 along with actual geographic information. The characteristic observation stations were selected and the degree of vegetation cover, projective cover and phytomass in the zone of the Siyazan-Sumgait massif were fixed .Four degrees were determined for visual aeolian relief forms, density of vegetation , distance from the sea, geographical state of the surrounding area and other differences, soil deflation. These are weak, mild, strong and very strong. Absolute heights of the semi-stationary example and observation pitches selected within the research zone are -17 m and 0 m. Takyric Solonchak semitype soils were formed against the background of interaction of Gypsisols with ecogeographical factors. The soil samples were taken from upper accumulative horizons on four pitches for researching the effect of long processes of deflation on soil cover taking into account the deflation index. General physical, chemical analyses of the soil samples were carried out. It was found that the influence of deflation process on soil cover changed depending on degree of vegetation cover. Deflation intensifies the salinization and solonetzification process in the zone along with the effect of deflation on the physical characteristics of the soil. The influence of deflation process on grey and grey-brown soils changes depending on the season of the year along with the state of the vegetation cover . The fraction composition of the wind was determined and it was found that the amounts of Ca (from cations), Cl (anions) and sulphate were higher than the others.

In this year, the Chimica Techno Acta journal (CTA) celebrates its 10th anniversary. A tenth of a century is a long time, during which about 350 papers have been published. In the beginning, the journal has been edited in two formats (electronic and print) and in two languages (Russian and English), but then considerable efforts have been made to ensure the rapid consideration of manuscripts while maintaining high peer-review standards at the same time. CTA has become an exclusively English-language and online journal. As a result, authors currently receive a first decision on their manuscripts within 17 days of submission, while the total time from submission to publication of a final version does not exceed 50 days. Along with providing good conditions for our authors, the journal seeks all possible ways to improve the quality of its content by considering well-designed manuscripts for their publication. Therefore, the rejection rate is increased from 10–20% in 2014–2015 to almost 50% in 2022.Another point consists in the support of the published items by visual facilities that have online journals. To avoid boredom, we changed the layout from grayscale to color and then to different colors for each year. The current (10th) volume is published in an orange-based design, symbolizing sunrise, warm sand, and juicy peach. We believe that visual content has a strong focus on the readers' attention. Even though the color perception may not impress someone, we will definitely change the coloristics in next year.The CTA Editorial Board is constantly updated with new scientists to ensure a more accurate review of incoming manuscripts. Within the current editorial, we are pleased to welcome a new editor, Dr. Pavel Padnya from Kazan Federal University (Russia). A short interview with him can be found below.
Intercultural Historical Thinking and its Sense in the History of Civilization
Authors: Yu Peiyun
Published: December 2024

This article explores the importance of intercultural historical thinking in the age of globalization and its significance to the historical study of civilization. The article points out that in the context of globalization, human beings are still faced with different understandings of heterogeneity, otherness and homogeneity. Historical research is an important way for societies to realize their cultural functions and cultural orientations, while intercultural historical thinking and historical research are particularly valuable because of their practical significance. The article emphasizes the major role of historical consciousness in intercultural historical thinking, and believes that historical consciousness is not only about the cognition of the past, but also a historical interpretation of the present. Through the mutual communication of historical consciousness, we can better understand the conceptual type and cultural background of others, so as to rebuild the consensus of the community of humanity in the age of globalization. In addition, the article also explores the ontological construction of historical consciousness, regarding that this helps to introduce grand concepts such as “civilization” into a concrete and practical context, and promote mutual understanding and mutual learning among different civilizations.

Published: December 2024

The study is devoted to morphological parameters of the leaves of Salix alba, S. euxina and S. × fragilis. Salix alba samples for the study were selected in the herbarium of the Perm State University (Perm) and signed by I.V. Belyaeva in order to avoid the possible inclusion of hybrid plants. Shoots from cultivated plants of S. euxina and S. × fragilis were collected in August 2024 in Perm. Model shoots were selected from the illuminated part of the crown. All fully developed, more or less symmetrical leaves from the central part of the current year's growth are measured on them. The length and width of the leaf blade leaves were measured using CorelDRAW 2019. The blade shape coefficient was calculated as the ratio of its length to width, the distance from the base of the leaf blade to its widest part, the length of the petiole, and the angle of the apex of the leaf blade was determined. Statistical data processing was performed using PAST 4.13. It was found that the shapes of leaf blades in the studied species have quite definite differences that allow us to fairly confidently differentiate closely related taxa

One of the approaches to assessing the efficiency of agricultural practices in growing agricultural crops is population analysis with the identification of manifestations of individual and population life strategies of cultivated plants and their varietal specificity. The studies were conducted in 2024 at the Chishminsky Breeding Center of the Bashkir Research Institute of Agriculture. The object of the study was the ‘Bashkir’ variety. We studied the morphological structure of the aboveground vegetative sphere and its variability in variants with a planting density of 17.8; 26.7 and 53.3 thousand tubers/ha. We studied the patterns of variability of 11 morphological traits: number of shoots; plant height (the most developed shoot); number of leaves on the most developed shoot; number of pairs of large lobes of the leaf blade, leaf length and width, petiole length of the most developed leaf of the middle formation; length and width of the blade of the most developed leaf lobe, indices of leaves and the most developed leaf lobe. One-way analysis of variance revealed a reliable effect of planting density on most traits, with the exception of leaf indices and the lateral leaf lobe. The adaptive nature of variability of such traits as the number of pairs and sizes of the lateral lobes of the leaf blade, demonstrating convergent and divergent ontogenetic tactics, respectively, was established. The structure of morphological variability with the allocation of groups of indicator traits was revealed. Traits with low rates of general and coordinated variability are classified as genotypic (taxonomic) indicators: plant height, number of leaves, leaf length, number of pairs of leaf lobes, leaf lobe index, leaf index. The length and width of a leaf lobe, leaf width are classified as biological indicators with low general and high coordinated variability. High general and low coordinated variability are characteristic of ecological indicators that depend most on external conditions - petiole length and number of shoots. No systemic indicators have been identified. The influence of variability in the aboveground vegetative sphere on the structure of potato yield remains to be studied.

Combinations of genetic variants and environmental factors are responsible for the development of many human diseases. Information on individual capacity to accumulate DNA damages is essential to advance the development of personalized disease prevention in environmentally exposed populations. Coal-fired thermal power plants burn huge amounts of coal per year and emit corresponding amounts of toxic gases, ash, and volatile organic compounds. The elements that make up coal are a large group of diverse pollutants associated with threats to human health and the environment. The current work is based on identifying the risks associated with the health of workers at coal-fired thermal power plants. The study is devoted to the assessement of the DNA damage degree in connection with individual sensitivity in 455 workers of coal-fired thermal power plants in the city of Kemerovo and 533 residents of the same region not associated with production. The research materials are represented by 988 samples of peripheral venous blood from residents of the Kemerovo region. Control donors were selected according to the gender, age, and smoking status of coal-fired power plant workers. Micronucleus testing with a cytokinetic block on peripheral blood lymphocytes was used to register DNA disorders. Determination of the influence of genetic factors on the degree of DNA damage was carried out using allele-specific polymerase chain reaction of polymorphic variants of the DNA repair system genes APEX1 rs1130409, ERCC2 rs13181, PARP1 rs1136410, hOGG1 rs1052133 and ERCC5 rs17655. Increased frequencies of DNA disorders were detected in carriers of the heterozygous genotype of the APEX1 gene and minor variants of APEX1, ERCC2, hOGG1 and ERCC5.

Deneme Kırklareli ili Pınarhisar ilçesinde İrem Çamlıca Bağcılık ve Şarapçılık Ltd. Şti. bağında yürütülmüştür. Bitkisel materyal olarak on yaşında olan; Papazkarası/1103P, Papazkarası/110R ve Papazkarası/420A aşı kombinasyonu omcaları seçilmiştir. Çalışmada farklı anaçlara aşılı Papazkarası üzüm çeşidi salkımlarından alınan tanelerin özellikleri belirlenmiş ve tane heterojenitesinin tane özelliklerini nasıl etkilediğinin ortaya konmuştur. Bu amaçla, hasat edilen salkımlardan alınan taneler boyutlarına göre sınıflanmıştır; ≤12 mm (B2); 12,01-14,00 mm (B3); 14,01-16,00 mm (B4); 16,01-18,00 mm (B5) ve ≥18 mm (B6). Ayrıca kontrol (B1) boyut grubu toplam tane sayısının tane boyutlarına dağıtılmasıyla oluşturulmuştur. Tane özelliklerini ortaya koymak için; tane eni-boyu, tane yaş ve kuru ağırlığı, 100 tane ağırlığı, tane hacmi ve 100 tane hacmi kriterleri incelenmiştir. Ayrıca; tane özkütlesi, % kuru ağırlık, TKA/TH, şeker konsantrasyonu, tanede şeker miktarı, 1g tanede şeker miktarı ile verim belirlenmiştir. Sonuç olarak, düşük vigora sahip 420A anacının tane özellikleri açısından şaraplık çeşitlerde istenilen en düşük değerlere sahip olduğu; öte yandan tane özkütlesi, % kuru ağırlık ve TKA/TH değerlerinin de yüksek olması sebebiyle öne çıktığı belirlenmiştir. Tane boyutları açısından da en yüksek tane sayısının 12,01 mm ile 18,00 mm arasında yer alan boyut gruplarında olduğu saptanmıştır. Üzüm kalitesi açısından bu boyutlar arasındaki taneler, yüksek kaliteli olmamakla birlikte şarap üretimi için idealdir. Öte yandan B2 (≤12,00 mm) ve B6 (≥18,00 mm) boyut gruplarında istenilen tane sayısına erişilememiştir.

The dynamics of material particles with intrinsic angular momentum (spin) described by the general covariant Dirac equation in a homogeneous stationary rotating space-time is considered. It is shown that in such a space-time, there is a homogeneous stationary vortex gravitational field and the angular velocity of rotation of the vortex gravitational field is uniquely related to the magnitude of the mass of the particle. Using this result, a rotating electromechanical model of electron is constructed which is presented in this paper.

The hole transport in chromium-compensated gallium arsenide (HR-GaAs:Cr) sensors is studied using the transient current technique and numerical simulation of the photoresponse of an HR-GaAs:Cr sensor to a single pulse of infrared radiation. The object of research were HR-GaAs:Cr sensors with a grid metal contact to which a positive potential was applied. It has been established that when the sensor is irradiated from the grid anode, electron drift in the horizontal direction to the sensor strips is observed, leading to the formation of a photocurrent pulse with a duration of less than 1 ns in the electrical circuit. It has been established that the observed areas of exponential decay of the photocurrent at the trailing edge of the pulses are due to the drift of holes towards the cathode of the sensor accompanied by capture by negatively charged chromium centers. Based on the results obtained, the lifetime of holes in the samples under study was determined.

Published: December 2024

A numerical study is performed of an impinging jet with a passive control using a grid at the inlet to enhance mixing and heat transfer on the heated surface, with which the jet collides. It is shown that with increasing the Reynolds number, the Nusselt number at the stagnation point on the wall grows according to a power law corresponding to the empirical approximation. The introduction of the grid allows us to enhance significantly heat transfer in the central part of the jet. The effects found in the calculations and the prospects for research are discussed in the course of comparison with the measurement data.

In this work, the coalescence of an uncharged water droplet suspended in oil with a layer of water under the action of an alternating electric field was numerically investigated. The coalescence modes were compared in cases of using a constant and an alternating sinusoidal electric field. It was found that the frequency and phase of touching (at frequencies close to the natural frequency of droplet oscillation) have the greatest effect on the volume of the separating droplet, while other parameters contribute less. It is shown that when an alternating electric field is used, a scatter in the values of the volume of the separating droplet appears, which is determined by the phase, at which the droplet touches the layer. When the voltage frequency increases, the volume scatter decreases and tends to the values obtained at the constant voltage.

The paper presents the results of comprehensive study of high-temperature plastic deformation macrolocalization in Ni3Ge alloy single crystals with the L 12 structure under creep conditions. Structural studies of the processes of macrolocalization band formation were carried out using optical, scanning electron microscopy and the EBSD analysis (electron backscatter diffraction method). It is shown that the localization band is a crystal macrovolume with an average rotation angle of » 45° relative to the total volume of the sample. The internal structure of the band consists of irregularly shaped subgrains elongated along the localization band with misorientation angles of 1-5°. Schemes illustrating the mechanisms of substructural transformation in the macrolocalization band are presented. It is assumed that structural transformations in the localization band are associated with intensive diffusion creep of edge dislocations interacting with deformation point defects and the formation of low-angle boundaries.

For the first time, the shape memory effect (SME) during reversible FCC↔HCP martensitic transformation (MT) was studied on the [͞111]-oriented single crystals of Cr20Fe20Mn20Co35Ni4.9C0.1 high-entropy alloy under deformation conditions: at a temperature M s for the start of direct MT during cooling in the «load-unloading» cycle and at constant tensile stress in the «cooling-heating» cycle. It is shown that the FCC↔HCP MT is characterized by the temperature of the onset of direct MT upon cooling M s = 250K and a wide thermal hysteresis of 150K. The maximum SME was 4.3% at a tensile stress of σt = 275 MPa at a constant increase in σt from 75 to 275 MPa in the «cooling-heating» cycle and 6.7% at repeated «load-unloading» cycles at a temperature M s. When studying the SME under stress in the «cooling-heating» cycle and when studying the temperature dependence of the yield strength σ0.1(T), a difference in the stresses of martensite formation under stress was found, which was 100 MPa at a temperature M s.

This study explores the impact of substituents (ethoxycarbonyl, mesityl, benzyloxycarbonyl, 2,4,5,7-tetramethylnaphthyl-1, and N-benzylformylamil) in a series of porphyrin derivatives on the internal conversion rate constant k IC between the excited electronic singlet states S1 and S2. It was shown that k IC increases from 1.17·108 s-1 for free porphyrin to 1.8·1010 s-1 in the presence of substituents. The substituents affect mainly the magnitude of the matrix element of the non-adiabatic coupling operator, while the energy gap between the S2 and S1 states remains almost constant. Additionally, the contribution from the non-adiabatic mixing of S2 and S1 states does not exceed 2%, thus making it permissible to use the adiabatic approximation when modeling the photophysical properties of the studied compounds.
