Physiological responses of bread and durum wheat seeds to osmotic stress and salinity in the early germination stage
Authors: Catav Şukru
Published: November 2023

Determining the mechanisms underlying tolerance to osmotic stress and
salinity during the germination period is an essential task in order to
improve agricultural production in arid and semi-arid areas. In this work,
the seeds of bread and durum wheat cultivars were treated with different
concentrations of polyethylene glycol (PEG)-6000 and NaCl for 1 week, and
half-maximal inhibitory concentrations (IC50) of germination were
calculated. The seeds were then exposed to IC50 values of NaCl and PEG-6000
for 2 days in order to assess their physiological and biochemical
properties. Alpha and beta amylase enzyme activities, the reducing sugar,
total sugar, proline, protein, and H2O2 contents, and DPPH radical
scavenging activity of the seeds were determined by spectrophotometric
methods. The results showed that the bread wheat seeds had a much higher
tolerance to excess salt and osmotic stress than the durum wheat seeds. In
particular, the average IC50 value of NaCl for the bread wheat cultivars was
almost twice that for the durum wheat cultivars. The imbibition test
revealed that the water uptake capacity of the seeds did not explain the
difference in tolerance to these stress conditions. On the other hand, the
bread wheat seeds exhibited constitutively higher proline, total sugar, and
H2O2 contents as well as antioxidant capacity compared to the durum wheat
seeds (p < 0.05). In conclusion, the current findings suggest that the
interplay of oxidative metabolism and compatible solutes may contribute to
improving germination tolerance under water deficit and salinity conditions
in wheat.

New manifestations and meanings of Orthodox Lity - preservation of identity and sacralization of space and time in the Belgrade’s (and broader Serbian) context
Authors: Todorovic Ivica
Published: November 2023

In the text, we primarily deal with the observation of the latest
manifestations of the Orthodox lity procession ritual and ways of
sacralising the space on the example of Belgrade. Accordingly, attention is
also paid to the symbolism of different spatial landmarks, which is
emphasized at the level of several semantic layers. Recent events have once
again actualized the importance of the Lity procession ritual - deeply
rooted in both folk tradition and religion - as well as its manifestations,
both in the Republic of Serbia and in the wider Serbian ethnic area. The
basic and most visible function of Lity is the consecration and marking of
space, but also of time, with special significance for a certain
ethnic-social context, community or place. However, Lity also have a
pronounced cohesive and identity function, as was particularly clearly
demonstrated in the example of the defense of holy sites, i.e. of basic
religious rights, precisely through Lity in Montenegro. Consequently, Lity
proved to be one of the most effective weapons against attempts to
deconstruct the Serbian identity. In accordance with the relevant
indicators, in our work, with a multidisciplinary approach, various
structural and semantic dimensions and possibilities of Lity are considered.
This primarily refers to the level of the Belgrade area, but in a more
general sense it is also directly related to field and other research on
related issues, which were carried out in a much wider area during the
previous decades.
Pedestrians and pedestrian streets in Belgrade: An anthropological take on space, mobility, and hospitality industry in the city center
Authors: Radovic Srdjan
Published: November 2023

In the past decades, Belgrade experienced a significant transformation of its downtown area also with regards to an increasing number of public spaces turned into pedestrian zones, primarily by closing roads for automotive transport, and establishing new pedestrian zones. This trend of pedestrianization of urban cores in Europe (initiated in the mid-20th century), found its strongest expression in Belgrade in the eighties with the complete transformation of Knez Mihailova street and its paving, and later with the expansion of the pedestrian zone to the adjoining streets. With the beginning of the 21st century, a special rise of a commercialized type of ?street life? occurred - an increasing number of outdoor restaurant facilities were established. In the last twenty years, the services sector has become one of the most important in the city?s economy, and the tourism and hospitality industry employs a significant number of people; thus, the urban public space is increasingly adapting to the needs of consumers of such services, residents and guests alike. The visible expansion of restaurant facilities on public pedestrian areas in Belgrade raises questions about priorities in the use of public space. This paper will examine questions of space use, pedestrian mobility, and hospitality industries.
The city as multispecies space: Dog walking in downtown Belgrade during the COVID-19 lockdown
Authors: Zakula Sonja
Published: November 2023

This paper represents an autoethnographic account of dog walking in a
residential area of downtown Belgrade during the COVID-19 lockdown of early
2020. It is also an attempt at, or rather, the result, of the largely
experimental practice of canine-assisted ethnography, as my dogs Dita and
Ripley were instrumental during fieldwork. The lockdown, with its
ill-thought-out and constantly changing rules about dog walking underlined
three basic issues: 1) in a city with a huge dog owning population, public
policy with regard to this issue is virtually non-existent; 2) the city
lacks public green spaces, and 3) the movement patterns of dog walkers tend
to converge due to the fact that the needs of the canines (both biological
and social) are embedded into the architecture and planning of local
neighborhoods. In this sense, the city emerges as a multispecies space, and
the social patterns and walking routes of its residents who keep dogs are
influenced, if not completely determined by the human-animal bond at play.
This became especially visible during lockdown at times when dog walkers
were the only people allowed outside. Thus, this paper analyzes how
interspecies (in this case human-dog) relationships shape the functions of
urban space in Belgrade.

territory of Belgrade. An attempt shall be made to present this practice in
its entirety, with all its particularities, based on data obtained in the
field (through interviews with performers), Internet sources (YouTube
videos, texts, etc.), and academic literature. The Romani practice is
possibly the most common street musical practice on the territory of
Belgrade, and while it is undoubtedly diverse, it still possesses numerous
characteristics which shape its particular identity. Therefore, the elements
of the aforementioned musical practice shall be presented and analyzed,
including: 1. forms of musical performance, 2. types of performing
ensembles, 3. choice and condition of the instruments used in performing, 4.
choice of musical repertoire, 5. the language being sung in, 6. choice of
public spaces at which it takes place, 7. events and special occasions
during which this musical practice occurs, 8. career development and 9.
child exploitation. The aim of the paper is to provide a relevant insight
into the special musical identity of the Romani street musical practice in
Belgrade by way of analyzing the segments of this street musical practice
presented. Moreover, the goal of this research is to construct a model which
may serve to conduct further research into the Romani street musical
practice in other Serbian cities, as well as enable a comparative analysis
and insight into the common, general features of this musical identity.

Authors: Møller Christina Tanem , Tafjord Gunnar , Blindheim Augun , Berge Viktor , Fosså Sophie , Andreassen Bettina Kulle
Published: November 2023

Before immunotherapy became part of the management of metastatic bladder cancer (mBC), systemic anti-cancer treatment comprised primarily of platinum-based chemotherapy. The objective of this study was to describe the characteristics, the initial management, overall survival (OS) and hospitalisations of patients with mBC before 2018 when immunotherapy for mBC was introduced in Norway. 
Material and methods: It is a nationwide population-based study of primary mBC patients (diagnosed 2008-16). Descriptive statistics were applied and stratified for four initial management options (≤150 days after BC diagnosis): chemotherapy, major local treatment (cystectomy/pelvic radiotherapy), multimodal treatment (chemotherapy and local) and no anti-cancer treatment beyond transurethral resection of bladder tumour (untreated). Group differences were evaluated by Chi-square and Kruskal–Wallis test; OS was estimated with Kaplan–Meier.
Results: Of the 305 patients included, 76 (25%) patients had chemotherapy, 46 (15%) patients had major local treatment, 21 (7%) patients had multimodal treatment and 162 (53%) patients were untreated.  Median OS ranged from 2.3 months (untreated) to 9.8 months (chemotherapy). Patients who received treatment had a higher rate of hospitalisation, with a median stay of three to four times that of untreated patients.
Conclusion: Before immunotherapy, more than 50% of patients with primary mBC did not receive any initial anti-cancer therapy and had a poor survival. Patients treated with chemotherapy had inferior median OS compared to those treated with comparable systemic strategies in contemporary trials. Our results provide a basis for future research on treatment and survival after the introduction of immunotherapy for mBC, aiming to improve the care and outcome of patients with mBC.
Study of Micro-arc Oxidation as a Method for Improving the Technical Characteristics of AA5086 Aluminum and VT6 Titanium Alloys
Authors:   OOO «ZVO «INNOVENT», Medvedev D.L. , Sedova N.A. ,   ООО «Vibrozashchita»
Published: November 2023

The article presents the promising field of micro-arc oxidation as a surface modification method with the purpose to improve the corrosion resistance of titanium, aluminum, aluminum alloys and composites. Micro-arc oxidation is an electrochemical process that forms a thick, hard and highly adhesive ceramic oxide layer on the metal surfaces, thereby providing excellent protective properties. This method of hardening the metal surface was used in production in the manufacture of parts from AA5086 and VT6 alloys for industrial fans operating in chemically hazardous facilities. When using micro-arc oxidation, the strength and wear resistance of the internal parts of the fan to aggressive medium was increased. By that increased the trouble-free operation time and reduced the likelihood of destruction of the internal parts of the fan, which subsequently made it safer for employees to operate the fans in close proximity to the work area. This work examines the corrosion resistance of aluminum alloys and composites, since the indicated materials are also widely used in various branches of industry. It also considers the role of alloying elements in influencing corrosion behavior, as well as the influence of microstructure and processing methods on corrosion resistance. In addition, the discussion extends to the corrosion behavior and protective measures for aluminum matrix composites, including the inclusion of reinforcing phases such as ceramic particles, fibers or nanoparticles. Throughout the article, the corrosion resistance of micro-arc oxidation treated surfaces, anodized aluminum layers, aluminum alloys and composites are critically assessed, analyzing the factors influencing their protective characteristics, such as the morphology, composition and thickness of the oxide layers, as well as environmental factors.

The technology for conducting degassing work in the Russian mines is determined by the experience of half a century of using methods and means to reduce the methane abundance of excavation areas based on drilling wells along the developed and adjacent coal seams into mined-out spaces. The parameters of degassing and methane emission sources are legalized by the industry regulations, scientifically substantiated, and published in the scientific and practical works. The mines of the Kuznetsk coal basin and the Vorkuta deposit, mainly with high productivity of coal mining in the conditions of developing a suite of methane-bearing coal seams using complex mechanized faces were selected as objects of study: named after S.M. Kirov, named after V.D. Yalevsky (formerly «Kotinskaya»), Boldyrevsky coal seams (index 24) and seam 52. Gas hazard of the coal mines is determined by the volume of methane emissions, explosions of methane-air mixtures, loss of people life and is caused by the joint influence of natural, mining, organizational and subjective factors. The main indicator of gas hazard when developing a suite of methane-bearing coal seams is the absolute methane abundance of the excavation area. The method was used to predict the intensity of methane release from the exposed surface of a mined coal seam into the bottomhole space of the longwall and adjacent coal seams. Methane release from the exposed surface of a contiguous coal seam, subject to unloading from the rock pressure, was determined by analogy with the mined seam. The release of methane from the broken coal was established experimentally. When the working face unloads adjacent coal seams, the intensity of methane release from them into the working face is summed up.

Based on the results of the conducted analysis of existing methods effectiveness for extinguishing of oil and gas blowouts, a fundamentally new method for suppressing their combustion using high-pressure generators of fire extinguishing aerosol on a pasty aerosol-forming composition is proposed, which ensures the minimum extinguishing time and minimum costs compared to any other methods of extinguishing such fires. In a chamber with a volume of more than 70 m3, the minimum fire extinguishing concentration of the aerosol is determined. Based on the obtained value, the calculation of the minimum number of fire extinguishing aerosol generators required to extinguish fires of oil and gas wells having a large flow rate was carried out. A series of large-scale experiments on extinguishing a gas blowout with a flow rate of 1 million m3/day and an oil blowout with a flow rate of 1500 m3/day confirmed the efficiency of using paste-like aerosol-forming compositions to create installations for extinguishing oil and gas blowouts, as well as the correctness of the proposed method for calculating the number of fire extinguishing aerosol generators required for extinguishing. The supply of fire extinguishing aerosol along with the flow of burning oil or gas provides an extremely short blowout extinguishing time of 3–4 s from the moment the generators start to work.
The Impact of Accounting for Industrial Hazards on the Efficiency of Occupational Risk Management
Authors:   National Research University Moscow State University of Civil Engineering, Sugak E.B.
Published: November 2023

In accordance with the decisions of the Government of the Russian Federation, the occupational safety management system is being reformed in the country. The new model of this system, built on the basis of occupational risk management techniques, in particular, using the Deming — Shewhart cycle, makes it possible to qualitatively improve the prevention of occupational injuries. To methodologically support the transition to a new model of labor protection, the main regulatory documents were prepared and approved, and additions were made to the Labor Code of the Russian Federation. However, the introduction of preventive mechanisms to improve working conditions is hampered by the problem of taking into account injuries of light and moderate severity. The established long-term practice of ignoring a significant number of industrial hazards conflicts with the requirements of mandatory implementation of procedures for managing occupational risks, which affects the efficiency of the activities carried out. In particular, in the European Union countries 10–40 times more accidents are registered than in Russia, but at the same time the injury severity rate there is 10 times lower. The International Labor Organization, using a special indicator on fatal injury statistics, suggested that the real number of people injured at work in Russia could range from 600 thousand to 1.2 million people in year. Using the example of Heinrich injury pyramid, the methods for recognizing industrial hazards that are in an obvious and hidden state are considered. Evidence-based statistics on the positive impact of the number of identified hazards on workplace safety are also provided. Taking into account the existing practice of risk accounting, it is proposed to use the injury severity coefficient as the main indicator of production safety. At the same time, one should strive not to reduce the injury frequency rate, but, on the contrary, to increase it, which will indicate an improvement in the recording of injuries.

Dynamics of the antioxidant-prooxidant balance of the kidney under conditions of acute blood loss of various degrees and its correction
Authors: Denysiuk Yu.A. , Нudyma A.A.
Published: November 2023

The purpose of the study is to find out the dynamics of the antioxidant-prooxidant balance of the kidney during acute blood loss of various degrees and to evaluate the effectiveness of correction with Ringer’s lactate solution in combination with 2-ethyl-6-methyl-3-oxypyridine succinate.Material and methods. 126 male Wistar line rats weighing 0.16-0.18 kg were randomly selected for the experiment. Four experimental groups and one control group were selected. Acute blood loss of 1% of body weight was simulated in experimental group 1, acute blood loss of 2% of body weight was simulated in experimental group 2. In experimental group 3, acute blood loss in the amount of 2% of body weight was simulated, and after 1 hour, Ringer’s lactate solution was injected once into the adjacent vein in a ratio of 1:1 in the amount of blood loss volume. In experimental group 4, after simulating acute blood loss in the amount of 2% of body weight, Ringer’s lactate solution in combination with 2-ethyl-6-methyl-3-hydroxypyridine succinate at a dose of 100 mg·kg-1 was injected into an adjacent vein once. A control group of rats was only injected with thiopental sodium anesthesia. After 1, 3, and 7 days, catalase activity, the content of reagents to thiobarbituric acid were determined in the kidney, and their ratio - the antioxidant-prooxidant index (API) was calculated.Results and discussion. It was established that acute blood loss within 1-7 days of the experiment is accompanied by the accumulation of thiobarbituric acid reagents in the kidney and by a decrease in catalase activity and the value of API. Disturbances depend on the volume of blood loss and are significantly greater under conditions of acute blood loss in the amount of 2% of the mass. The injection for correction with Ringer’s lactate solution in combination with 2-ethyl-6-methyl-3-oxypyridine succinate compared to monotherapy with Ringer’s lactate solution leads to a significant decrease in the content of reagents to thiobarbituric acid in the kidney, and an increase in catalase activity and the value of API, starting from the 3-rd day of the experiment.

To carry out an analysis of data from the world literature regarding the role of Doppler assessment of blood flow in the venous duct of the fetus in chromosomal abnormalities in the first trimester of pregnancy, as a marker – the spectral form of wave blood flow and its pulsation, which is generated by changes in the pressure and volume of blood to the heart of the fetus. Prenatal diagnosis of venous blood flow makes it possible to assess the state of the fetal cardiovascular system. Blood flow in the ductus venosus is an integrative indicator that reflects the formation of blood circulation of both the uteroplacental and placental-fetal components of gestational hemodynamics during physiological and complicated pregnancy. The performance of this test is 63%, and in combination with the assessment of the thickness of the clavicle – 89.1%. When reverse values of blood flow in the ductus venosus are detected in the phase of contraction of the atrium and dilated cervical space, it is necessary to carry out karyotyping to rule out chromosomal abnormalities. Dopplerography allows us to objectively assess the functioning state of the fetus during physiological and complicated pregnancy based on the study of the state of blood flow in the vessels of the placenta, in the middle cerebral artery, thoracic aorta, renal arteries, inferior vena cava and venous duct. The spectrum of venous blood flow reflects changes in volume and pressure in the atria during the cardiac cycle. With normal fetal development, blood flow in the venous duct has a pulsating character in the form of a unidirectional three-phase curve that corresponds to different periods of the cardiac cycle. The spectrum of normal blood flow in the venous duct in a healthy newborn has a biphasic curve, with the direction from the portal sinus to the inferior vena cava. During three weeks of regular examinations in most babies, obliteration of the venous duct occurs, and the ductus turns into a venous connection. Two-dimensional echocardiogram, color and pulsed dopplerography allow recording the waveforms of blood flow in several structures of the heart. Doppler analysis of blood flow in the venous duct is important to perform in fetuses of the first trimester, as it increases the sensitivity of the combined test in assessing the risk of chromosomal disorders. Assessment of blood flow in the ductus venosus provides an understanding of physiological and pathological processes in the fetal body and identifies fetuses that are prone to or at risk of disease.

Authors: Kramarchuk V.V. , Vysochyna I.L.
Published: November 2023

Acute respiratory infections (ARIs) annually rank first in the structure of infectious diseases both in Ukraine and worldwide. ARIs are the leading cause of disability and death in preschool children, and with recurrent episodes, they can impact the physical and psychological aspects of children's health, imposing a significant medical burden on families, healthcare systems, and society as a whole. Preventing recurrent respiratory infections (RRIs) can only be achieved through timely intervention in risk factors.Aim: to determine the influence of risk factors on the development of recurrent episodes of acute respiratory infections in children aged 5 to 7 years and to develop preventive measures for their control in primary healthcare settings.Materials and Methods. The authors retrospectively analyzed medical records of 342 children aged 5 to 7 years. The main group included children with RRIs (264), and the control group consisted of children with sporadic illness episodes (78). Results: the incidence of RRIs in children has two peaks at ages 3 and 6, which is likely associated with the commencement of attendance in childcare settings (kindergarten and school). Key prenatal and postnatal, clinical-anamnestic, and social risk factors that increase the likelihood of recurrent respiratory infections in younger school-age children were identified.Conclusions. factors significantly increasing the likelihood of developing RRIs in a child include: ARI episode within the first 6 months of life (OR = 22, 95% CI 11.6 - 41.7), previous pneumonia (OR = 12, 95% CI 3.7 - 40), and the presence of chronic infection foci in the form of tonsillitis (OR = 8.2, 95% CI 4.3 - 15.6), p=0.0001. Primary healthcare practitioners should follow strategies to modify these risk factors and not wait for further depletion of the child's adaptive potential (sanitation of chronic infection foci, promotion of breastfeeding, and tobacco cessation).

Published: November 2023

Teacher research constitutes an integral component of a pedagogue's professional activity, serving the purpose of comprehending and transforming the pedagogical reality through the application of scientific insights and methods. One of the benefits of such endeavors is enhanced research competence. The present paper delves into the approaches to developing research competence of students within the higher education institutions of European countries. The research methods include literature analysis, systematization (to elucidate key research concepts), comparative analysis (to discern the peculiarities of research competence development among students in European higher education), and synthesis (to formulate original conclusions). Based on the synthesis of scientific approaches (including the personal, activity-based, competence-based, systemic, knowledge-based, procedural-technological), research competence is construed as an integral quality of an individual, encompassing skills for conducting research to address educational issues and instructional management. A systematic examination of the approaches to research competence development among students in Germany, the United Kingdom, and France reveals a consistent and methodical progression. In the early stages of formal education, students are exposed to research-oriented learning, while in subsequent phases, they actively participate in undergraduate and graduate research. A recurring theme is the early engagement of students in research activities, bolstered by specific pedagogical conditions and teaching methodologies. These conditions include the encouragement of students' involvement in research, the reinforcement of interdisciplinary dimensions, and the pivotal role played by research advisors in coordinating student research endeavors. Additionally, active teaching methods, such as discussions, workshops, seminars, simulations, situational analyses, practical experiences, internships, and independent research, significantly contribute to the effective engagement in research activities. Project-based and problem-oriented learning methods emerge as predominant didactic approaches, seamlessly blending students' autonomous work with collaborative endeavors within small research groups. Key forms of research competence development encompass lectures, seminars, practical sessions, and consultations. These educational formats not only motivate students to apply their acquired knowledge in practical contexts but also ignite their enthusiasm for independent exploration, fostering creativity.

Caatinga, the Brazilian tropical dry forest and source of endemic species, suffers anthropic disturbances that are responsible for affecting plants and their functional traits. Therefore, we aimed to evaluate the plasticity woody species’ leaf traits due to abiotic conditions of preserved and anthropized areas in Caatinga. The study took place in Vale do Riacho São José, in the municipality of Caetés, Pernambuco, Brazil. The selected species were Mimosa tenuiflora, Mimosa arenosa and Senna sp., all belonging to the Fabaceae family. We measured gas exchange, water content, specific leaf area and phenotypic plasticity index of all selected species in both areas. For all species, stomatal conductance was higher in preserved areas, but photosynthesis followed this pattern only for Senna sp. which also showed lower water use efficiency among all species. Furthermore, Senna sp. presented the highest relative water content in preserved areas, and showed no differences in specific leaf area between preserved and anthropized areas. The plasticity index showed that Senna sp. were the most plastic species, mainly adjusting water content and gas exchange parameters according to the area. The less plastic species was Mimosa arenosa. A principal component analysis showed a group formation due to anthropization, for all species. However, Senna sp. showed the largest distance among species. We conclude that all analyzed species respond to environmental conditions of preserved and anthropized areas, but this pattern cannot be related to the characteristics of the botanical family due to species-specific leaf traits’ variations.

In this research study, the development of a theoretical model to estimate the efficiency of a double pass solar air heater (DPSAH) was the main objective. The mathematical model was compared to experimental results and found to be in agreement, both qualitatively and quantitatively. The model used energy balance equations to determine the outlet temperature and could solve the temperature equations of each component of the heater simultaneously. A matrix inversion method was used for this purpose. The study found that increasing the Nusselt number led to an increase in energy efficiency, but also caused a drop in outlet temperature at any solar radiation. The mass flow rate (MFR), with larger flow rates resulting in better efficiencies, had a significant impact on the double pass air heater's efficiency. Thus, increasing of DPSAH’s length increases its thermal performances and reach its maximum values for L=9m. These findings could be beneficial in selecting the most efficient design parameters for DPSAH.

The present work aims to investigate the structural and thermodynamic properties of homogenous tetragonal Cu2ZnSnS4 (CZTS) absorber material in Kesterite phase using first-principle calculations based on density functional theory (DFT). This approach requires only knowledge of the atomic species and crystal structure to predict several physical properties of materials. The Quantum Espresso code within the Ultra Soft pseudopotentials (USPP) and the local density approximation (LDA) were used in the calculations. Equilibrium unit cell volumes, bulk modulus, as well as the pressure derivative of the bulk modulus are predicted. In addition, several thermodynamic properties, especially: the Debye’s vibrational energy, the vibrational free energy, the vibrational entropy, and the constant volume heat capacity at different temperatures T of Cu2ZnSnS4 material are calculated and discussed. Our study shows that the vibrational energy, the entropy and the constant volume heat capacity increase with increasing temperature, while the vibrational free energy decreases monotonously with the increase of temperature.

As a fossil fuel-dependent nation, Kazakhstan is caught between issues and possibilities in its search for a sustainable energy transition. Despite its tremendous resources, Kazakhstan’s renewable energy capacity is 1%, much behind its non-renewable peers. According to this research, green fiscal policies in renewable energy firms are needed to reduce the country’s political and economic dependence on the global oil sector. This report emphasizes regional collaboration and Kazakh-stan’s potential leadership in Central Asian Green Economy projects. Kazakhstan can promote renewable energy adoption and economic sustainability by forming regional alliances.

Challenges lie ahead on the green future path, so this paper addresses legislative, infrastructure, financial, and data barriers to green fiscal initiatives in Kazakhstan. It stresses the significance of holistically tackling these concerns, including banking and stock market reforms and sustainable planning. Policymakers and stakeholders in Kazakh-stan can use the research findings to boost the economy, fight corruption, and increase political engagement. Upskilling the workforce to support green technology and local renewable energy production is recommended. The report recommends proactive global crisis prediction and management to help Kazakhstan handle economic and environmental challenges. Hence, the above actions are crucial to Kazakhstan’s goal of industrialization by 2050. Kazakhstan can lead a world rapidly moving to green energy by committing to green fiscal methods, regional collaboration, and addressing the many obstacles to development. By doing so, it can safeguard its future and advance the global green energy revolution.
