Bu araştırmada, ülkemizde alüminyum sanayinin kuruluşu, gelişimi ve mevcut durumunun değerlendirilmesi yapıldıktan sonra, sektör işletmelerinin mekânsal dağılımı ve dağılımında etkili olan faktörler ile küresel iklim değişikliğine
bağlı olarak Avrupa Birliği’nde (AB) şekillenen politikaların sektöre etkileri üzerinde durulması amaçlanmaktadır. Ülkemizde alüminyum sanayii, 1990’lı yıllardan itibaren otomotiv ana ve yan sanayii, beyaz eşya sanayii ve gemi
inşa sanayii ile inşaat sektöründe yaşanan gelişmeye bağlı olarak hızlı bir gelişim süreci göstermiştir. Bu sektör, özellikle 2000’li yıllarda sağlanan genelde ekonomik istikrar ve adı geçen sektörlerin büyümesine bağlı olarak
oluşan iç talep nedeniyle önemli bir gelişme göstermiştir. Sektörde faaliyet gösteren işletmeler çoğunlukla küçük ve orta ölçekli işletmelerden oluşmaktadır. Türk alüminyum sanayii, büyük ölçüde birincil alüminyum tedarikçisi,
mamul ve yarı mamul alüminyum üreticisi ve ihracatçısı niteliği göstermektedir. İhracatımızın %50’den fazlasını gerçekleştirdiğimiz Avrupa Birliği’nin (AB) Sınırda Karbon Düzenleme Mekanizması (SKDM) ile karbonu ton başına vergilendirdiği
bir gelecekte sektör işletmelerinin rekabet avantajını koruyabilmesi için ihracatçılarımızın karbon ayak izlerini ölçtürmeleri, düşük karbon üretimi için yol haritalarını çizmeleri, hazırlıklı olmak adına büyük önem taşımaktadır.
Bununla birlikte ülkemizde %70 civarında olan alüminyum geri dönüşüm kapasitesinin arttırılması, teknolojisinin geliştirilmesi, sertifikasyon süreçlerinin işletilmesi enerji yoğun birincil alüminyum üretimden kaynaklanan karbon
salımlarını büyük ölçüde düşürerek, AB’ye ihracatta rekabet avantajımızı güçlendireceği açıktır (Vurdu, 2022: 72).

Potential Irregularities in Arrangements of Amendment Regarding the Term of Office of Village Heads in the Indonesian Constitutional Law System
Authors: Mahardika Ahmad Gelora
Published: December 2023

The discourse to extend the term of office of the village head creates problems in the Indonesian constitutional system. This is because the addition will potentially extend the term of office of the village head to 27 (twenty-seven) years. In fact, cumulatively, the term of office of the village head based on Law Number 6 of 2014 concerning Villages is quite long, namely 6 (six) years and can be elected 3 (three) times, which means that the village head can serve 18 (eighteen) year. On the other hand, the duration of a village head, which has the potential to reach 18 years, is also essentially inconsistent with democratic principles which provide a maximum limit for public officials who are elected through political mechanisms to hold office. For this reason, the idea of reconstructing the village head's term of office has become an urgent issue in the Indonesian constitutional system. The research question in this article is whether there is a potential for irregularities in the arrangements regarding the extension of the village head's term of office. The type and research approach used in this article is comparative normative juridical research with a statutory approach. The hypothesis in this article is that the long term of office of the village head is contrary to the concept of democracy, namely the limitation of power.

Retrospective analysis of the determining factors for open reduction in pediatric humerus supracondylar fractures: Are factors such as time until operation and surgeon's experience effective?
Authors: TAŞCI Murat , KARATAS Muhammed Enes , KEMAH Bahattin
Published: December 2023

Aim: indications for open surgery are very limited in supracondylar humerus fractures (SCHFs).
In our study, we aimed to examine whether the patient’s fracture type, waiting time of the patient before the operation, and the experience of the surgeon are effective on the treatment decision for open surgical method in our SCHF patients treated with open reduction.

Methods: A group of pediatric patients treated with open reduction for SCHF between the years of 2010 and 2022 were examined for our study. Trauma mechanism, type of fracture, time until operation, neurovascular injuries and years of experience of the surgeons were retrospectively reviewed.

Results: A total of 110 patients were included in the study. The mean age was 5.7 years. Nine patients were flexion-type SCHF. According to the Gartland classification, 19 patients were Type II and 82 patients were Type III. Ninety-four patients were operated in the first 24 hours, 16 patients were operated after 24 hours. There was no statistical correlation between the surgeons’ experience or time until operation and the type of the fractures. Patients with flexion type fractures were significantly older than the other patients.

Conclusion: Extension Type III fractures are often require open surgery regardless of the surgeon's experience and waiting time for surgery. Regardless of the surgeon's years of experience and the type of the fracture, some fractures cannot be treated with closed reduction and require open reduction.

Authors: DURSUN Muhsin
Published: December 2023

Aim: Our study aims to report the neurovascular heterodigital island flap reconstruction for finger pulp defects.

Patients and Methods: This study included 58 patients presenting to our clinic with pulp defects between 2014 and 2022. The average age of the patients was 26 years (20 - 56 years). Injuries were Allen type 2 for 18 patients, type 3 for 33 patients, and type 4 for 7 patients. Pulp defects were caused by crush injury (n:42) and sharps injury (n:16).

Results: None of the flaps administered to the participating patients developed any total loss. Three patients developed partial loss in the distal flap. Six patients were found to have superficial tissue infection. Two patients were found to have hyperpigmentation and hyperesthesia. While one patient with Allen type 3 pulp defect was detected to have 10 degrees of flexion contracture in the distal interphalangeal (DIP) joint and 5 degrees of flexion contracture in the proximal interphalangeal joint, three patients were found to have 5 degrees of flexion contracture only in the DIP joint. The mean static two-point discrimination of the pulp-administered flap was 5.2 mm (3-8 mm) and on the contralateral side was 3 mm. The mean Semmes-Weinstein monofilament test was 3.18 g (2.96 – 4.7 g) in the pulp administered flap and 2.92 g in the contralateral side.

Conclusions: Reconstruction of pulp defects with neurovascular heterodigital island flap is a reliable treatment option with satisfactory functional and sensory outcomes.

Çalışmanın amacı, öncelikle enflasyon oranı (beklenen ve gerçekleşen), döviz kuru (beklenen ve gerçekleşen), CDS primi ve TL cinsinden mevduata uygulanan faiz oranı açısından dolarizasyon oranının kaynağını tespit etmek ve sonrasında ise dolarizasyon oranının asimetrik yapısını incelemektir. Bu amaçla 2013:01 ile 2023:04 dönemine ait aylık veriler kullanılarak VAR Analizi ve Hatemi-J Asimetrik Nedensellik testi uygulanmıştır. Dolarizasyonun kaynaklarının incelendiği Varyans Ayrıştırması’na göre, Türkiye ekonomisinde dolarizasyon oranı üzerinde en etkili olan değişkenin döviz kuru (%19.8) olduğu sonucuna varılmıştır. Diğer taraftan, değişkenler arası nedensellik ilişkisinin incelendiği asimetrik nedensellik analizine göre, dolarizasyon oranı ile döviz kuru, enflasyon oranı ve risk primi arasında simetrik bir nedensellik ilişkisi var iken, dolarizasyon oranı ile faiz oranı arasında ise herhangi bir nedensellik ilişkisi söz konusu değildir. Dolayısıyla döviz kuru (beklenen ve gerçekleşen), enflasyon oranı (beklenen ve gerçekleşen) ve risk primindeki bir düşüş dolarizasyon oranının azalmasının veya tersine dolarizasyonun bir nedenidir. Buradan hareketle, beklenen ve gerçekleşen değerlerin benzer sonucu verdiği görülmektedir.
Some features of using steel when renovation of buildings and structures
Authors: Yehorov Yev.A. , Ivchenko Yu.V. , Kupnievych L.V. , Karasik I.V.
Published: December 2023

Problem statement. Steel as a material with high strength properties is very widely used in construction. But its production processes are associated with high energy consumption, and its availability in the country can vary significantly. The use of this material should always be seriously substantiated. Ukraine is currently in a temporary situation when, on the one hand, metal production has fallen sharply, while, on the other hand, in construction its needs have increased significantly. Purpose of the article. Firstly, the authors show some ways of significantly reducing metal consumption while providing a sufficient level of reliability by using the example of steel tanks for storing oil and petroleum products. All the authors' proposals are based on numerous data of tanks field inspections that have been in operation for 20…30 years or more. Secondly, the article gives examples of steel effective use in the renovation of old and partially destroyed civilian buildings made of brick and reinforced concrete. Some proposals for the fast mass construction of housing are considered, which is also very relevant today, and also, as in the buildings renovation, requires the steel costs. Conclusions. Today in Ukraine the demand for steel has increased, on the one hand, and at the same time, its production has decreased. This requires the involvement of all opportunities for more efficient use of steel in building structures, namely: the wider use of thin-walled structures, the use of effective rolled profiles, comprehension and adjusting regulations, which unreasonable steel costs are included.

Problem statement. New compositions of foundry bronzes in which the best levels of properties inherent in both tin and aluminum bronzes are combined need to be developed. Purpose of research. Regularities between mechanical properties indicators and alloying components content in bronze of Cu−Sn−Al system with tin and aluminum content up to 6 % each are obtained. Methodology. Alloys for investigation was prepared by technical purity primary charge materials melting in induction crucible furnace using graphite crucible and charcoal as a coating material. Investigated alloys mechanical properties was calculated based on tests results of corresponding samples during their static elongation and impact bending at room temperature according to actual standards. Alloys chemical composition control was carried out on precision analyzer EXPERT 4L on samples cut from cross-shaped samples. Investigated multicomponent system response surfaces plotting was performed by H. Scheffe simplex-planning method with models of fourth and third degree. Results and discussion. According to Cu−Sn−Al alloys research results, functional dependences between mechanical properties vs. Sn and Al content from 1 to 6 % by weight of each are determined. This makes it possible to predict the level of mechanical properties according to chemical composition of such bronze during casting. Conclusions. It was found that within tin and aluminum content in investigated limits the best combination of mechanical properties has bronze BrO3A3 with content of Sn = (3…4) % and Al (3…4) %. Bronze BrO3A3 has higher (including plastic) mechanical properties values compared to the properties of tin bronzes, which are most often used in industry. This gives the reason to recommend such bronze for shaped castings and friction bearings manufacturing.

Problem statement. The globalization of the world economy and the rapid development of machinery and technology necessitate the balanced development of the construction industry and agriculture. Under such conditions, investment and innovation processes become an integral part of production activities. At the same time, the effectiveness of investment and innovation activities largely depends on the applied management methods and management organizational structures, in accordance with modern challenges and needs. In this regard, the role of a science-based approach to the development, planning and implementation of cluster projects, taking into account the characteristics of industries, changes in the environment, as well as factors influencing the investment activities efficiency of design and construction organizations and agricultural enterprises. Purpose of the article. Definition of preconditions, benefits and prospects of clusters’ formation and development in the construction and agricultural sectors of the economy (on the example of Dnepropetrovsk region) using the project approach based on SWOT-analysis of construction and agricultural clusters. Conclusions. In times of crisis, the application of the cluster approach as a progressive management technology is most appropriate, given that they allow accelerating innovation processes for new products, application of advanced technologies, expanding markets, improving the efficiency of organisational management structures, implementing the necessary environmental measures, etc. The cluster approach to the organisation of construction and production-agricultural activities is to combine the efforts of the state, business and science to increase the competitiveness of enterprises, the rational use of natural resources and more. Formation of construction and agricultural clusters is the key to effective implementation of investment and construction projects with minimal risks through public-private partnership.
EFFECT OF HEATING TEMPERATURE AND COOLING RATE ON THE FORMATION OF STRUCTURAL COMPONENTS IN STEELS
Authors: FILONENKO N.Yu. , BABACHENKO O.I. , KONONENKO G.A.
Published: December 2023

Formulation of the problem. One of the key areas of research into the mechanical properties of steels lies in developing methods of manufacturing steels with a grain structure and a high degree of carbides dispersion or other inclusions that will be located in the pearlite grain as a result of heat treatment. Changes in external factors such as temperature, pressure etc. are known to cause changes in the structural components of alloys and steels. The most usual way of fixing the high-temperature state for metal systems is through hardening, which is the removal of heat at high rateIt is known that microcomplexes formation is possible in melts at temperatures exceeding the liquidus temperature. There is much research of melts at temperatures above liquids for the presence of stable microcomplexes in binary alloys. However, there are no data on heat flow above the liquidus line for phase formation during crystallization and the structural components formation in steels. Purpose of research − investigation of chemical composition effect and heating temperature above the liquidus line and cooling rate on the structure formation in steels. Methods. Microstructural, micro X-ray spectral and X-ray phase analyses to determine the steel structural properties are used. Results. A new type of heat treatment including heating of the experimental steels with the alloy system (K + (Al + N + Ti)) and (K + (Al + + N) above the low-temperature line by 50...150 ºC is suggested and investigated. Subsequent cooling at rates of 102…105 ºС to fix the melt high-temperature state after experimental steels heating over the liquidus line by 50…150 ºС is performed. As a result of such processing the dispersed structure which is strengthened by dispersed inclusions is formed. The inclusions were < 0,1 μm in size and were evenly distributed in the grain volume and partially along the boundaries. The martensite formed by the steel rapid cooling had a finely differentiated and rail-like morphology. Scientific novelty. A new method of steel processing is proposed. Regularities of structural components formation in the heat treatment process including steels’ heating over the liquidus line by 150…170 ºС is determined. Practical significance. This method of thermal action influence allows to receive the homogeneous structure strengthened by dispersed inclusions. The method allows choosing the optimal modes of differentiated heat treatment to obtain the most homogeneous structural state and specified mechanical properties.
FEATURES OF THE CRACKS’ FORMATION IN HETEROPHASE INCLUSIONS OF THE “DISPERSED PHASES IN A NON-METALLIC MATRIX” TYPE

Published: December 2023

The purpose of the article − to study of crack nucleation features in heterophase inclusions of the “dispersed phases in a non-metallic matrix” type under the conditions of steels’ plastic deformation. Methods. The research was conducted after deformation for a number of different grades steel samples in the temperature range of 20...1 200 °С on Instron-1195 and IMASH-5C with special grippers, with a gripper movement speed of 1 680 mm/min. Research methods were used: petrography, micro-X-ray spectral analysis (Cameca MS-4, Nanolab-7), optical microscopy (Neophot-21). Results. It is shown that the variety of phases composing the heterophase inclusions "dispersed phases in non-metallic matrix" leads to their different behaviour under plastic deformation conditions. At the same time, the nucleation of brittle or viscous microcracks occurs along the internal interphase boundaries between the "non-metallic" matrix and the dispersed particles of the second phase. The cracks’ character near the inclusions determined by the plasticity level of “matri” and dispersed phases of inclusions and the deformation temperature are revealed. The determined critical degrees of samples’ deformation, upon reaching which appreciable microcracks along the internal interphase boundaries occurred, were depend on temperature and the nature of the “dispersed phases in a non-metallic matrix” inclusions. Scientific novelty. The features of microcracks nucleation associated with heterophase inclusions of the “dispersed phases in non-metallic matrix” type with different combination of brittle and plastic phases during steels’ deformation are determined. The types of microcracks occurring in inclusions of the “dispersed phases in the non-metallic matrix” type and the locations of their formation have been determined. It is shown that the values of the deformation critical degrees determine the level of cohesive strength for internal interphase boundaries in heterophase inclusions “dispersed phases in a non-metallic matrix” at different deformation temperatures. Practical value. The use of the obtained results will make it possible to develop technologies for producing steels with regulated types of non-metallic heterophase inclusions that will allow to increase significantly their technological and operational characteristics, and also to prevent the formation of various defects in the steels' treatment by pressure and the operation of products.

The purpose of the article − to study of crack nucleation features in heterophase inclusions of the “eutectic of inclusion-matrix” type during steel deformation. Methods. The research was conducted after deformation for a number of different grades steel samples in the temperature range of 20...1 200 °С on Instron-1195 and IMASH-5C with special grippers, with a gripper movement speed of 1 680 mm/min. Research methods were used: petrography, micro-X-ray spectral analysis (Cameca MS-4, Nanolab-7), optical microscopy (Neophot-21). Results. It is found that the variety of phases composing the heterophase inclusions of the "eutectic of inclusion-matrix" type leads to their different behaviour under conditions of plastic deformation. It is shown that the nucleation of brittle or viscous microcracks occurs along the internal interfacial boundaries between the metal matrix and the second phase of the eutectic. It is defined that the cracks’ nature is determined by the plasticity level of the inclusion phases and the deformation temperature. It is shown that the critical degrees of samples’ deformation, at which appreciable microcracks along the internal interphase boundaries appeared, depend on the temperature and the nature of the inclusion phase “eutectic of inclusion – matrix”. It is found that the values of deformation critical degrees determine the level of cohesive strength for internal interphase boundaries in heterophase inclusions “eutectic of inclusion – matrix”. Scientific novelty. The features of microcracks nucleation in heterophase inclusions of the “eutectic of inclusion − matrix” type are determined. It is shown that the nature of the microcracks formed along the interphase boundaries depends on the temperature, plasticity level and combination conditions of brittle and plastic phases in inclusions of the “eutectic of inclusion − matrix” type as well as on the deformation temperature. It is shown that the critical degrees of steels deformation, when microcracks appeared along the internal interphase boundaries, determine the cohesive strength of these boundaries and depend on the temperature and the nature of the inclusion phase “eutectic of inclusion − matrix” type. Practical value. The use of the obtained results will make it possible to develop technologies for producing steels with regulated types of non-metallic heterophase inclusions that will allow to increase considerably their technological and operational characteristics, and also to prevent the formation of various defects during steel pressure treatment and product operation.

Purpose. To consider possible factors of influence on the formation of structural and grain unevenness of carbon steel. Methodology. Based on the analysis of the existing literature, the influence of various factors on the structural heterogeneity in carbon steels is analyzed. Results. From the analysis of the literature, a number of reasons were identified that affect the formation of heterogeneity in the structure of carbon steels. These factors include: chemical composition, dendritic liquation and processing liquation, non-metallic inclusions, mechanisms of austenite grain formation, initial grain size, and steel contamination with gases. Scientific novelty. On the part of the chemical composition, chemical elements such as carbon, copper, aluminum, silicon, nitrogen, sulfur and phosphorus affect the liquation formation. The formation of the microliquation level is also significantly influenced by the type of the formed structure. It has been shown that the level of segregation with directional crystallization is much higher than with equilibrium crystallization. Also, the formation of the final structure is associated with a hereditary influence in the production of metal products of the structural features of the parent metal, which depend on various technological factors. The contribution of certain metallogenetic signs of technological heredity occurs at all stages of melting, crystallization, structure formation, solid-phase transformations; different types of thermal, deformation-thermal, deformation processing, etc. In most cases, it is technological factors that are responsible for the structural features and manifestations of the metallurgical and structural heredity of metals and alloys. The dispersion of the dendritic structure, which grows with an increase in the crystallization rate, has a significant effect on the development of dendritic segregation in the ingot. With an increase in the dispersion of the dendritic structure, the total crystallization surface grows and a significant part of the liquid metal solidifies at higher temperatures. Practical significance. As a result of the performed review of the literature, the main factors influencing the formation of the final structural and grain unevenness were determined in accordance with modern points of view. Determination of the basic principles and the most effective factors will make it possible to confidently assume the possible microstructure of steel both in the cast state and after heat treatment.

NiO nanoparticles were synthesized using the vacuum arc sputtering method. The influence of synthesis parameters on the structural and magnetic properties of the samples was studied. X-ray diffraction analysis confirms the polycrystalline nature of the resulting nanoparticles under all deposition conditions, but the preferred crystallite orientation depends on the deposition conditions. Magnetic behavior correlates with the crystallite size of NiO nanoparticles. Condensates with particle sizes in the range of 4–6 nm exhibit superparamagnetic behavior, which changes to antiferromagnetic behavior as the particle size increases.

Using lead loadings in the form of single plates with different weights and physical surfaces, as well as sets of different numbers of plates and approximately the same total mass during its oxidation in organic phases containing molecular iodine and hydrogen peroxide simultaneously and only hydrogen peroxide as an oxidizer, a simulation of the possible consequences of rolling lead particles with bulk shapes into thin plates under the influence of mechanical factors in the course of oxidative processes has been carried out. It was established that single plates under the selected conditions were consumed in accordance with zero-order macrokinetics and velocities which increased with increasing the plate mass and decreasing its physical surface. The same trend persists in sets of plates: the more plates in the set while maintaining the total mass, the worse the process proceeds. At the same time, each set corresponds to its own type of the macrokinetic curve of lead consumption in the range from auto-accelerated development with a transition to the stationary or wave mode to auto-delayed development with an exit to a very slow, stationary mode close to zero order. Consequently, the rolling of particles of bulk forms into plates during the process automatically leads to a slowdown in the passing, which cannot be eliminated by external influence.

Risk assessment is performed in different conditions and for different purposes and very often it is followed by various types of uncertainty. Sometimes uncertainty is smaller, but usually during risk assessment a large number of factors appears with incomplete information to a greater or lesser extent. Risk assessment under conditions of uncertainty is less complex with the application of various mathematical fields dealing well with uncertainty. This paper presents one approach in the application of D numbers in the process of risk assessment, respectively, risk quantification. As is known, D numbers treat uncertainty very well, so this feature of them is also used in risk quantification. In this paper, first of all are presented basic terms related to the concept of risk, as well as of D numbers. The focus of the paper is on the examples in which risk assessment is presented using D numbers. In addition to the level of risk that is defined through the application of D numbers and standard tables for risk assessment, the paper also defines the level of optimistic or pessimistic risk. Thus, in addition to the risk value, the risk interval can also be obtained, which in conditions of uncertainty provides a much more realistic picture of the problem.

A tendency to procrastinate has been previously linked to low attentional control and poor emotion regulation skills. Building upon on these findings, in the present study we investigated whether the relationship between procrastination and attention can be mediated by emotion dysregulation and dispositional mind-wandering. Participants completed questionnaires along with the Attentional Networks Test for Interactions and Vigilance — executive and arousal components. The results showed that procrastination is inversely related to some indices of executive and arousal vigilance. Moreover, the emotion dysregulation and dispositional mind wandering fully mediated these relationships. Obtained findings suggest that lower attentional control might exacerbate chronic procrastination through difficulties in managing emotional reactions and poor control over the focus of one’s thoughts.
