TO THE QUESTION OF MODERN CHANGES OF CLIMATE OF NORTHWEST BLACK SEA REGION
Authors: Svetlitchnyi A. A. , Ibragimova M. S.
Published: October 2023

Purpose. In recent years, climate indices, the majority of which belongs to the category of so-called «extreme indices», widely used in international practice for assessing global and regional climate changes. The purpose of this article is to identify the characteristics of climate change, the North-Western Black Sea region since the beginning of the twentieth century through the use of climate indices.
Data & Methods. For the analysis and evaluation of the changes of climate of the North-west Black Sea region have used the series of monthly, seasonal and annual values of the most informative climate indices for weather station Odessa-GMO for the period 1900-2015 from the site of European Climate Assessment & Data (ECA&D) project. In total have used 22 indexes, 12 of which are temperature, 5 – precipitation, 5 – complex. Analysis and assessment of climate change made using the comparative–geographical, graph-analytical and statistical methods of analysis.
Results. During 1900-2015 years according to observations at the meteorological station of Оdessa-GMO had been an increase both air temperatures and precipitation amount. In so doing in the long-term course of most of the indices manifested the periodicity of changes with the characteristic average size equal to 62-64 years.
The most intensely during this period occurred raising the minimum air temperature. While the coefficient of linear trend of average annual air temperature (TG index) equals 1,23° C / 100 years, for the absolute annual minimum of air temperature (TNn index) this coefficient equals 2.97° C / 100 years.
Since the late 70-ies of the last century has been a significant increase in the intensity of warming. In particular, over the last 35 years the average annual air temperature increased by 2° C, the annual minimum air temperature increased by 4° C, more than in 2 times there was an increase the number of «summer days», in 3.5 times increased number of «tropical nights», and in 1,5 times reduced the number of «frosty nights». It should also be emphasized that in the dynamic of precipitation amount over the last 35 years the monotonicity of changes, typical for the temperature indexes, is absent.
In the seasonal aspect most intensive growth both of air temperature and precipitation as a whole for period under consideration is typical for winter, the least an intensive –for the summer, which led to a decrease in annual amplitude of air temperature and equalization of distribution within the year of precipitation amount, respectively. At the same time in the last 35 years against the background of a slight increase in summer precipitation significantly increased their intensity.

Instrumental-operational strategy for the implementation of a cognitive-pragmatic program: cognitive-mental tools (Article 2)
Authors:   Xi’an International Studies University, Ivanov Dmitry I. , Lakerbai Dmitry L. ,   Ivanovo State University
Published: October 2023

The present offers an understanding of one of the significant original author’s concept aspects of cognitive-pragmatic programs in the context of the theory of intentionality. The instrumental-operational strategy — a cognitive project (action plan) of the source subject, aimed at the successful implementation of one or several strategic goals of the cognitive-pragmatic programs is being studied. The direct object of study consideration is a complex of the instrumental-operational strategy cognitive-mental tools. The cognitive-mental indexing of the instrument-signal has two main levels: basic and specification. Each updated tool, in addition to the basic indexing (“how”), receives a triple specification indexing (target “how”, self-identifying “how”, and resultant “how”). The same cognitive-mental tool, when used in discourse signals of different intentionality, can be indexed differently. On this basis, according to the type of dominant index, four main types of cognitive-mental tools can be distinguished. The first type: the central level of indexing is “target”; peripheral level — “self-identification”, “result”, “assessment”. The second type: the central level of indexing is “self-identification”; peripheral level — “goal”, “result”, “assessment”. The third type: the central level of indexing is “result”; peripheral level — “self-identification”, “goal”, “assessment”. The fourth type: the central level of indexing is “assessment”; peripheral level — “self-identification”, “result”, “goal”. Each of the cognitive-mental tools can occupy two main positions in the space of an intentional discourse signal: discourse / program-forming; corrective and clarifying. The universality and adaptability of the cognitive-pragmatic program theory, applicable as a subjective cognitive-pragmatic matrix to any meaningful and directed activity, makes it possible to detect cognitive-mental tools in other areas. And the more “synthetic” the area under study is, the more clear the “tools” are.
The image of Stalingrad in journalism 1942–1943: Stable images and topos
Authors:   Moscow University of Finance and Industry, Korzhova Inessa N.
Published: October 2023

In the article, based on the materials of the central press of 1942–1943, the leading images, motives, toposes (verbal formulas) forming the image of the warring Stalingrad are identified. The special significance of the Volga image as an image closely connected, on the one hand, with military realities, and on the other — based on folklore tradition and topos of the song generation (“Russian river”) is revealed. The main components of the Stalingrad landscape are established: the image of a raging river, the remains of houses, a red or smoky sky. The landscape also contains a sound image — the roar of a cannonade. These elements are perceived by the publicists themselves as somewhat canonical, so the essays about the victorious Stalingrad (late January — early February) emphasize the transformation of these components or a change in the tone of their description. It was found that the main metaphors that serve to create the image of the city are associated with the concepts of “living – dead – mutilated” and “fortress – stone”. Frequent use of motives generates phrases approaching the verbal formulas “Stalingrad is alive”, “Stalingrad is not a fortress, its people are a fortress”. The emphasis is not so much on the ideologies as on the deep images of the mythological genesis in the formation of the image of the city.

Published: October 2023

Aim: The aim of the present preliminary case-control study was to test the sensitivity and specificity of salivary pipecolic acid in predicting head and neck squamous cell carcinoma (HNSCC). Methods: High-performance liquid chromatography was used for the analysis of non-stimulated saliva samples from 40 individuals: 20 in the case group (recently diagnosed with untreated HNSCC) and 20 in the control group (individuals without cancer). Both groups included patients taking daily oral hypoglycemic drugs (comorbidity). The case and control groups were matched at a proportion of 1:1 for sex and comorbidity. Results: Mean salivary levels of pipecolic acid were 169.38 ng/ mL in the case group and 114.66 ng/mL in the control group (p<0.001). Individuals who took oral hypoglycemic drugs had higher levels of pipecolic acid in both the case and control groups (p<0.001). The receiver operating characteristic curve analysis revealed 90% sensitivity and 65% specificity for head and neck cancer, with an area under the curve of 0.838 between the case and control groups. Conclusions: Pipecolic acid had high sensitivity for the diagnosis of HNSCC but low specificity in the sample analyzed. Our findings suggest that salivary pipecolic acid levels are associated with glucose homeostasis. Studies with larger samples are required to evaluate the specificity of this metabolite.

Adolescent-parent communication on SRH was significantly associated with the level of knowledge regarding sexual and reproductive health (ꭓ2 = 5.809, p-value = 0.01, df = 1). Similarly, there was a significant association with the perceived parenting style (ꭓ2 =3.932, p-value =0.04, df =1), living arrangements (ꭓ2 =6.376, p-value=0.01, df =1), and adolescent-parent communication. Conclusion: It concluded that adolescent-parent communication on SRH issues is not satisfactory. Creating an adolescent-friendly environment at home and conducting awareness programs with the help of the local government of the respective schools would help to increase adolescent-parent communication.
Use of heat recovery technology to increase thermal efficiency of rotary furnaces
Authors: Shcherbina Valerii , Ivanenko Olena , Sokolskyi Oleksandr , Vasilchenko Gennady
Published: October 2023

The article considers the problem of increasing the energy efficiency of rotary kilns, which are used in various industries for thermal processing of materials, such as metallurgical, chemical, construction, electrode and others. The source of heat for the kilns is gaseous fuel, which is supplied through special burners located at one end of the cylinder. The material for processing is loaded at the opposite end and moves towards the burner due to the force of gravity and rotation of the kiln. One of the important aspects of operating rotary kilns is energy efficiency, which depends on many factors and generally characterizes the degree of use of heat from fuel for heating the material. However, a significant part of the heat from fuel is lost through the kiln shell, which leads to an increase in fuel consumption and a decrease in kiln productivity. Therefore, it is necessary to look for ways to reduce heat losses and use part of the heat for other purposes. In this context, heating secondary air can be one of the important methods for increasing the thermal efficiency of rotary kilns, especially for kilns that operate in a mode for pyrolysis firing of materials such as coal, wood, peat, etc. The aim of the work is to increase the energy efficiency of a rotary kiln using a spiral heat exchanger, using the heat from the external shell of the kiln to heat secondary air. The paper proposes the use of a sectional heat exchanger, which can perform the functions of a cooler, a thermal insulator and a regulator of temperature regimes of the kiln. The heat exchanger consists of several sections that are attached to the outer surface of the kiln shell and have channels for air passage. The air is heated by contact with the hot shell and then supplied to the burner as secondary air. Thus, the heat exchanger allows to reduce the temperature of the shell and provide an additional source of hot air. A mathematical model for numerical calculation of a spiral heat exchanger has been developed, which allows to evaluate its thermal and temperature characteristics. It is shown that by using the heat from the shell it is possible to heat secondary air to a temperature of 270 °C in an amount sufficient to ensure the operation of the burner. An analysis of the location of the heat exchanger and the use of insulation coating has been carried out, which made it possible to significantly reduce its size without changing the total thermal effect compared to a heat exchanger installed along the entire length of the kiln shell. The effectiveness of using thermal insulation has been shown, which makes it possible to increase the temperature of air by 50 °C with its thickness 7 mm. The obtained results can be useful for further development and optimization of projects aimed at improving heat exchange systems and efficient use of thermal resources in rotary kilns.

Published: October 2023

Depression is a complex neuropsychiatric disorder characterized by pervasive feelings of sadness, hopelessness, and cognitive impairments that can profoundly impact an individual's quality of life. Despite extensive research efforts, the precise mechanisms underlying depression remain elusive. Recent studies have highlighted the intricate interplay between the immune system and the central nervous system in the pathophysiology of depression. In this context, CD4+ T cells, a key component of the adaptive immune system, have emerged as potential players in the neuroinflammatory processes associated with depression. Concurrently, Brain-Derived Neurotrophic Factor (BDNF), a multifunctional neurotrophin, has garnered significant attention for its roles in neural plasticity, mood regulation, and cognitive function. This review paper explores the intriguing intersection between CD4+ T cells and BDNF in the context of depression and delves into the exciting prospects it offers for therapeutic interventions. By examining the intricate crosstalk between the immune system and the neurotrophic factors, we aim to shed light on the potential avenues for novel therapeutic strategies in the treatment of depression.
Maximum thrust nozzle based on height constraint
Authors: Huang Bowen , Xu Jinglei , Yu Kaikai
Published: October 2023

Hypersonic aircraft focuses more on the integration of aircraft and engine than ordinary aircraft owing to high performance requirements, and the nozzle design is reflected in the required large area ratio of nozzle inlet and outlet and the compactness of the overall size of the aircraft. In this study, the height constraint is directly introduced into the maximum thrust nozzle design method. A new method for designing nozzles under the height constraints that consults the maximum thrust theory is proposed. Initially, the condition that the nozzle reaches the maximum thrust under the height constraint is deduced mathematically. Then, a nozzle design method satisfying the height constraint is computed using the method of characteristics (MOC). Subsequently, the influence of the design parameters on the design method is studied parametrically. Results show that Mach number scale and asymmetrical factors can affect ramp length and flap length of the nozzle, respectively. These factors great influence the axial thrust performance and lift under a specific height constraint. Compared with the traditional truncation design method, the thrust coefficient and lift increased by 11.93% and 138.45% respectively.

Authors: Riyanto Riyanto , Jinan Vika Nur
Published: October 2023

Demand for nutmeg essential oil in Indonesia and the world is increasing. Nutmeg essential oil is obtained from young nutmeg seeds extracted by water steam distillation (WSD). The weakness of the extraction process with WSD is the long distillation time (24 hours), wasteful of fuel, wasteful of manpower, produces polluting gases which damage the environment and requires a lot of water as a coolant. The purpose of this study was to compare the WSD and SCFE methods for extracting nutmeg essential oil. The research was conducted by extracting nutmeg essential oil using two methods are WSD and SCFE. The results showed that the chemical composition of the nutmeg essential oil produced by the two methods was almost similar. Nutmeg essential oil produced by both methods shows the same characterization. The yield between the two methods is almost the same, in the range of 10-12% using extraction time 15-60 minutes. The SCFE method has advantages over WSD are a faster extraction time, does not require heating materials and CO2 gas can be reused. In conclusion, SCFE is an alternative method to increase the production of nutmeg oil.

PROBABILISTIC COUNTERFACTUAL CAUSAL MODEL FOR A SINGLE INPUT VARIABLE IN EXPLAINABILITY TASK
Authors: Chalyi Serhii , Leshchynskyi Volodymyr
Published: October 2023

The subject of research in this article is the process of constructing explanations in intelligent systems represented as black boxes. The aim is to develop a counterfactual causal model between the values of an input variable and the output of an artificial intelligence system, considering possible alternatives for different input variable values, as well as the probabilities of these alternatives. The goal is to explain the actual outcome of the system's operation to the user, along with potential changes in this outcome according to the user's requirements based on changes in the input variable value. The intelligent system is considered as a "black box." Therefore, this causal relationship is formed using possibility theory, which allows accounting for the uncertainty arising due to the incompleteness of information about changes in the states of the intelligent system in the decision-making process. The tasks involve: structuring the properties of a counterfactual explanation in the form of a causal dependency; formulating the task of building a potential counterfactual causal model for explanation; developing a possible counterfactual causal model. The employed approaches include: the set-theoretic approach, used to describe the components of the explanation construction process in intelligent systems; the logical approach, providing the representation of causal dependencies between input data and the system's decision. The following results were obtained. The structuring of counterfactual causal dependency was executed. A comprehensive task of constructing a counterfactual causal dependency was formulated as a set of subtasks aimed at establishing connections between causes and consequences based on minimizing discrepancies in input data values and deviations in the decisions of the intelligent system under conditions of incomplete information regarding the functioning process of the system. A potential counterfactual causal model for a single input variable was developed. Conclusions. The scientific novelty of the obtained results lies in the proposal of a potential counterfactual causal model for a single input variable. This model defines a set of alternative connections between the values of the input variable and the obtained result based on estimates of the possibility and necessity of using these variables to obtain a decision from the intelligent system. The model enables the formation of a set of dependencies that explain to the user the importance of input data values for achieving an acceptable decision for the user.

Collaborative learning allows student’ interaction to the cognitive construction system. Social interaction in the learning system includes elements of the environment, technology, and learning methods that are implemented in the learning process. The aims of this study are: 1) to analyze correlation of collaborative learning and students' social interactions in teaching learning process and 2) to analyze whether there was bias publication or not in the meta-analysis of relevant research publications. The method used in this research is meta-analysis. The research was conducted by browsing the Scopus database on relevant research with the limitation of the keywords "collaborative learning" "social interaction" "correlation studies" for publication results between 2015-2022.  The data collected were 89 articles but the relevant ones were 12 articles with correlational studies. Data analysis used Effect Size test by JASP to answer the hypothesis about the relationship between collaborative learning and social interaction to determine whether there is bias publication. The results of analysis that used Random Effect model showed that there was a significant positive correlation between collaborative social learning and students' social interaction (z=3.379; p<0.005). The results of calculations regard to Rank Correlation showed that Kendall's value is 0.061 which showed the large correlation coefficient between effect size and variance where p-value of 0.841 is greater than the value of 0.05 which indicated that the publication sample data does not indicate bias publication. The results of this study indicate that collaborative learning in the direct social activities in the learning community. Meanwhile, indirect learning expands access to do discussion, publication capabilities, and reflection on various discoveries.

Zakat and tax play a crucial role in fostering the development of a country. Zakat is an obligation for Muslims, while tax is an obligation for all citizens. Therefore, this research aims to explore the prevailing local wisdom in the Kudus community, in order to gain insights into how these obligations are observed and complied with. The local wisdom philosophy of the Kudus community, known as ‘Gusjigang’, originated from the esteemed heritage of Holy Sunan. It embodies the values of good behavior, studiousness, and tenacious trading (entrepreneurship). Grounded by this philosophy, this study aims to comprehend the motivations behind the adherence of local entrepreneurs to zakat and tax using a case study approach. Following this, in order to gather relevant data, qualitative open-ended interviews and document analysis were employed as the primary source of data collection. Through this process, it was found that the prioritization of zakat over tax stems from the religious regulations and laws, which  take precedence over the mandates of fellow human beings. It is also important to note that from the perspective of the zakat administration, the distribution of zakat was considered more transparent and fairer as evidenced by the insights gleaned from the interviews.

The primary responsibility of the government is to safeguard the best interests of all citizens. In Indonesia, where the majority of the population follows Islam, the principles of poverty eradication through social safety system align with the constitutional guidelines. Among these principles are social assistance and mustahik Zakat. However, the process of obtaining accurate data on beneficiaries of social assistance often encounters challenges, leading to the emergence of inaccurate information. This is in line with Article 28 of Law of the Republic of Indonesia Number 13 of 2011 concerning Handling The Poor, where the government is required to develop a comprehensive plan to aid the impoverished. It also involves establishing a database of those in need and implementing efficient application methods. From this context, the data collection issues hinder the ability of the government to achieve critical objectives, such as poverty reduction and enhancing the overall well-being of the population. Therefore, this study aims to determine a position where Islamic and state law agree on the patterns of helping poor people eradicate poverty toward the coexistence of social aid and mustahik Zakat data, using a normative legal method. The results showed that a single set of data should include both the people obtaining social aid and mustahik Zakat, for poverty reduction to be successful and progressive. For data to be integrated, the rules guiding the agreement of everyone should also be emphasized, to ensure that poor people were obtaining help from social services or Zakat mustahik. This enabled the easy operation of programs, to help affected people eradicate poverty.

Microemulsions in the Oil and Gas Industry: A Review
Authors: Gangwar Aayushi Jagat , Maitra Sthitadhi
Published: October 2023

Objectives/Scope

Drilling fluids are crucial to the oil and gas industry, and so is the removal of filter cake formed by them. Pertaining to this, new improvisations are being made to achieve better rheology along with some other favorable properties. One of these advancements is the use of microemulsions as drilling fluids or as cement pre-flush. Novel microemulsion flushing fluids have been constructed for the effective removal of mud cake. The use of drilling fluids also creates the inevitable problem of formation damage, wherein the drilling fluid penetrates the formation and causes a decrease in permeability. Microemulsions have been used effectively to combat such damage caused by drilling fluids.

Methods, Procedures, Process

The main aim while preparing a drilling fluid is to obtain optimum rheology. And this is where microemulsions helped. The chemical/physical properties and damage mechanism of the formation were analyzed using several experimental methods, including X-ray diffraction, scanning electron microscopy, core inhibition test, etc. To develop an environmentally friendly drilling fluid, the main microemulsion system was constructed using an aqueous phase (water-glycerol solution 1:1), an oil phase (pine vegetable oil), and varying nonionic surfactants (Tween 80, nonylphenol ethoxylates 100 and 150). Two types of clays (filtration control) were used in the formulation of fluids, Brasgel PA and Cloisite 20 A, in the presence of a viscosifier (xanthan gum), a weighting agent (baritone), a sealant (calcite), and dispersant (water). For the effective removal of mud cake, the microemulsions for the flushing fluid were prepared with vegetable castor oil, 2%wt KCl as an aqueous phase, and a nonionic surfactant (Ultranex NP40). Various tests were performed to evaluate the performance of the flushing fluid formed.

Results, Observations, Conclusions

The use of microemulsion systems has led researchers to develop economical, environment-friendly, thermally stable, non-toxic drilling fluid or cement pre-flush that has low solid content, and low fluid loss. Microemulsions-based drilling fluids have also been used successfully to combat the problem formation damage in the Sulige gas field, in China.

Novel/Additive Information

This paper will review the numerous ways in which microemulsion systems are being incorporated into the oil and gas industry, particularly in drilling. It can help a drilling engineer come up with the Most Unexceptional way to prepare a microemulsion suitable for his needs, after going through the various methods and the properties achieved by them.

Ultra-deep fractured low-porosity sandstone gas reservoir is the most realistic unconventional oil and gas resource to be developed in China. However, reservoir is naturally fractured, non-homogeneous and artificially fractured, which makes the traditional analytical well test analysis method not applicable. To address this problem, the fractures are classified and characterized into small, medium and long scales according to practical understanding. A multi-scale fracture characterization method is developed utilizing a dual-porosity model to depict uniformly developed small fractures, while a discrete fracture model is employed to characterize medium and long fractures. Further, a numerical well-testing model for ultra-deeply fractured low-porosity sandstone reservoirs is established, namely a multi-scale dual porosity dual-zone composite model. Results show that the flow regimes can be classified as: wellbore storage and skin effect, acid-fracture influence, inner zone influence, transition flow, outer zone influence, and boundary effect. Based on the established numerical well-testing model, sensitivity analysis of the parameters is performed and well-test curve plates are drawn. It is observed that an increase in the number and length of natural fractures resulted in a deepening of the "depression" in the pressure derivative curve and a decrease in pressure losses within the test well. The curve characteristics in the early stages are predominantly influenced by acid-fracture parameters, whereas the degree of "depression" and its manifestation is impacted by the storage ratio and interporosity-flow coefficient. Finally, field applications are carried out to verify the reliability of the model. Notably, the target blocks are characterized by well-developed yet heterogeneous natural fractures. The results show that our numerical well testing analysis method has demonstrated greater accuracy and effectiveness in analyzing and interpreting such reservoirs.
