FLUID MIGRATION IS THE MAIN CRITERION OF THE GAS-BEARING CAPACITY OF THE CLOSED AREA OF MINES OF THE COAL-BEARING FIELDS OF THE DONBAS
Authors: Vergelska N. V.
Published: April 2024

Fluid migration is determined, first of all, by different in shape and rank types of dislocations that control compression and rarefaction zones as the main regulators of the distribution of matter and energy in the Earth's crust, represented mainly by Phanerozoic formations, and in our studies by carbon deposits. Gas migration through the newly formed fractures in the massif, due to the impact of mine workings on the upper layers of the lithosphere, allows for the formation of gas accumulations in the near-surface and surface areas. As a result, a significant amount of gas is concentrated in relatively small areas, which will contribute to gas-dynamic phenomena on the surface and can cause significant damage to buildings and human life.
Mass transfer of deep fluids is associated with the formation of mineral deposits, including the most explored ones, ore and oil and gas. At the same time, the distribution of gas in coal-bearing massifs is related to their tectonic structure, especially to faulting, which is a way for hydrocarbon-hydrogen mixtures to migrate from deeper horizons.
The study of the signs of uneven distribution of fluids under the influence of tectonic and anthropogenic factors was based on observations of new formations in the post-sedimentary geological environment: textural and structural characteristics based on the study of samples, grinds and laboratory observations, which determine the sequence of changes in the material composition of consedimentary and post-sedimentary formations and their relationship in space and time. Unsaturated hydrocarbons, such as ethylene, propylene and acetylene, can be characterised as adventitious gases of hydrocarbon massifs that have taken their current position in the gas component of the hydrocarbon gas mixture by being transported by fractures from deep horizons to the surface.

Authors: Mohamed Ahmed Sara Mahfouz , EL Ganzory Mona Mosatafa , Mamdouh Habeeb Nevin Mohamed , El Sayed Eman Mohamed , Mohammed Ali Hend Galal Eldeen , Abd Elaal Mohamed Omar
Published: April 2024

Background: Maternal diabetes mellitus (DM) is defined as a degree of glucose intolerance with recognition during pregnancy (pregestational or gestational, type 1 or type 2), and it is estimated to be 15% in pregnant females in 2019. The current study aimed to study the role of fetal echocardiography and fetal cardiac magnetic resonance imaging (MRI) in anticipation and diagnosis of hemodynamic maladaptation changes in fetuses of diabetic mothers as predictors for (closure of Patent ductus arteriosus (PDA), persistent pulmonary hypertension and diastolic dysfunction) which were confirmed with post-natal echocardiographic and clinical assessment.
Methods: This study was an observational follow-up study that included 80 pregnant diabetic females who were following in the specialized clinics of Ain Shams University Hospitals during the period starting from August 2020 till December 2022.
Results: Diabetes affected left ventricle (LV) diastolic function and global cardiac function but did not affect LV systolic function (p-value=0.000). Interventricular septum (IVS) thickness had a significant positive correlation with LV- Myocardial performance index (MPI) and indices of DM such as HbA1c. Diastolic dysfunction was the most affected cardiac parameter in infants of diabetic mothers (p-value=0.002). The hemoglobin A1c (HbA1c) was the most significant predictor for IVS thickness in diabetic mothers' fetuses, especially with a long duration of DM (p-value=0.012).
Conclusion: Fetal echocardiography in diabetic mothers is essential and the gold standard modality not only for diagnosing structural abnormalities but also for evaluating the cardiac function of the fetuses. Fetal cardiac MRI could be considered a complementary imaging modality that uses no ionizing radiation, good tissue contrast, and a larger field of view.

Authors: Chomchaiya Suvil , Yoosooka Burasakorn , Rodmee Chomanong , Naowaratphunsin Darunee , Kaichid Wannaporn
Published: April 2024

Due to the severity of the recent PM 2.5 and COVID-19 pandemic situations, the work-from-home lifestyle has been widely adopted as a new normal. Consequently, it’s necessarily preferable to cook at home instead of dining out as usual. However, a common problem is that there are unplanned and overstocked grocery items which are usually unrecognized and improperly managed. To address this issue, the "What To Cook" web application was developed with the theoretical application of Term Frequency-Inverted Document Frequency (TF-IDF) calculations to search for recipes based on the stocked groceries and then applied Cosine Similarity to calculate the similarity between each recipe and the stocked grocery items. Users can input the list of own stocked grocery items into the application and then apply the content-based filtering system to recommend recipes that can utilize the stocked grocery items.
Additionally, the application supports the image capturing using Google Cloud Vision API. The application also stores the user's cooking history and saves the under interested recipes for future reference. After testing the application in real-world scenarios, it was found to be easy to use with satisfiable results.

Microwave and ultrasound are novel technologies that are widely used for extracting bioactive compounds from plant materials. In this study, combined extraction techniques, microwave and ultrasound, were applied to extract cannabinoids, cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), from Cannabis indica L. (Blueberry cultivar). Three independent variables including solid to liquid ratio (X1, A: 1:10-1:30 w/v), microwave extraction time (X2, B: 5-20 min), and ultrasound extraction time (X3, C: 10-30 min) were optimized using central composite design (CCD). The experimental data obtained was fitted to a second-order polynomial equation using multiple regression analysis and additionally analyzed using appropriate statistical methods (analysis of variance, ANOVA). The optimum conditions were determined according to the solid to liquid ratio (X1, A) of 1:22 (w/v), microwave extraction time (X2, B) of 5 min and ultrasound extraction time (X3, C) of 14 min. Under these conditions, the experimental CBD and THC content was 0.298±0.001 mg/g dry weight and 91.35±0.35 mg/g dry weight, respectively. The experimentally-achieved values were in accordance with those estimated by the CCD model, suggesting the applicability of the utilized model and the favorable result of CCD’s application in the optimization of the combined microwave and ultrasound extraction.

Let \(G\) be a connected graph. A pebbling move is defined as taking two pebbles from one vertex and the placing one pebble to an adjacent vertex and throwing away the another pebble. A dominating set \(D\) of a graph \(G=(V,E)\) is a non-split dominating set if the induced graph \(\) is connected. The Non-split Domination Cover(NDC) pebbling number, \(\psi_{ns}(G)\), of a graph $G$ is the minimum of pebbles that must be placed on \(V(G)\) such that after a sequence of pebbling moves, the set of vertices with a pebble forms a non-split dominating set of \(G\), regardless of the initial configuration of pebbles. We discuss some basic results and determine \(\psi_{ns}\) for some families of standard graphs.

Published: April 2024

Users may receive personalised information services and decision support from personalised recommendations. In this paper, a hybrid algorithm-based personalised recommendation approach for learning English is proposed. The user model is created by merging user interest tags, and the Person Rank algorithm is then recommended based on user information. Second, the question-and-answer model is created once the question-and-answer data has been labelled, and the Problem Rank algorithm is suggested in accordance with the question-and-answer data. Then, the approach of tag-based recommendation, comparable user recommendation, and multi-dimensional sliding window are used to construct the recommendation algorithm model. The experimental findings demonstrate that, following the model’s training with the gradient descent technique, the recommendation accuracy is steady at around 0.78, the suggested information can accommodate users who are learning English, and the personalised recommendation effect is enhanced.

Published: April 2024

The global energy demand is rising, driven by population growth, economic development, and industrialization. Shifting towards renewable energy, like solar energy, is gaining momentum worldwide because of ecological concerns and resource depletion. This paper aims to utilize Artificial Neural Networks (ANNs) and multiple linear regression (MLR) modeling techniques to evaluate the productivity of 11 MW photovoltaic (PV) solar power plant currently operational in Jordan. The case study reveals that both models can be used to predict the daily, monthly, and yearly average power produced and system efficiency with reasonable accuracy. The ANN model exhibited promising results, where the best value for the coefficient of determination (R2) and mean absolute percentage error (MAPE) for training were 95.85% and 0.59%, respectively. However, R2 was 93.7%, and MAPE was 1.27% for validation tests. All these results were achieved using a 7-6-1 model, with a sample ratio of 1:1 for the data allocated in training and validation. When using multiple linear regression, the R2 and standard error values were 93.42% and 0.17%. On the other hand, the results showed that the yearly output power for actual and predicted by both models over the year was 24,399 MWh, 24,538 MWh, and 24,401 MWh, respectively. This research showed valuable results in the monthly output power for solar cells at the Anwaralardh PV power system project, contributing to a better understanding of solar energy generation in arid desert climates and emphasizing the potential of solar power plants to play a crucial role in achieving SDG 7 objectives.

The positive role of the employee cannot be underestimated in the organization's success because employees are the main asset of any organization; these unique assets must be fascinated through an organizational learning culture (OLC). They must also adapt to the changes in the organization to accept the challenges of the current era. Subsequently, this study expects to evaluate the impact of transformational leadership (TL) on faculty performance in Higher Education Institutions (HEIs). In addition, it examines the mediating role of organizational learning culture (OLC) between transformational leadership and employee performance (EP). Data is collected from HEIs in Pakistan. The questionnaire was adopted from past studies and distributed to 400 faculty members of business schools in Pakistan. The result of the study indicates that transformational leadership significantly impacts employee performance (EP) in the presence of a learning culture (mediating variable). The study's findings can be used in other organizations in Pakistan rather than only in academic institutions.

The rising scale and the intricate nature of these systems make the verification & validation (V&V) of classifications that are automated more costly and to much time-taking. Furthermore, the V and V  of the following systems might be hampered if the techniques and procedures are not effectively documented, assessed, and selected. Practitioners must employ appropriate V and V methodologies and conduct acceptable V and V procedures to ensure the following systems perform as proposed and in  cost-effective way. Earlier efforts have produced several categorizations and models that may be used to categorize V and V approaches and technologies. The goal of this study is to give a wide, comprehensive, and simple framework for characterization needs, rather than focusing on particular parts of V and V methodologies and procedures. To that purpose, in this study, we provide a multi-domained and multi-dimensioned framework for characterizing and classifying V and V approaches and tools in an organized manner. The framework reflects a complete description of several key features of V&V. As an example of usage, a web-based repository has been created based upon the framework to gather information regarding the use of V and V approaches and tackles. Experts and scholars may readily learn about and select acceptable V and V procedures this way.

The given research is aimed at solving the urgent problem of verifiable methods of forecasting cryptocurrency trading, with a preset focus on Stellar (XLM). Nevertheless, cryptocurrency forecasting is becoming more and more popular and it is still the case that there is a deficiency of research devoted to the use of the most advanced models to Stellar XLM price data. In many instances, the existing studies may pay less attention to the specific features of this cryptocurrency, hence creating a gap between our knowledge and understanding of how its prices fluctuate. Our experimental approach will investigate what accuracy forecasting models, especially the ARIMA model, can come up with by predicting the price of Stellar XLM. The purpose of this research is to experiment with a dataset for several years to know the workability of theoretical results on the forecasting models of Stellar XLM cryptocurrency. Our experimental research evidenced the acceptable price accuracy when forecasting Stellar XLM prices. Regarding the volume data, our metrics are a MAPE (Mean Absolute Percentage Error) of 16.82% and MSE (Mean Squared Error) of 7.41.10 -15 and Accuracyman (Accuracy) of 83.18%. On the other hand, the data with very high data recorded the best performance, with a MAPE of 4. 26%, MSE = 0.00025, and Accuracy of 95.74%. This finding again evinces that applying the more advanced models of forecasting and choosing appropriate data sources is key in a good Stellar XLM forecast. Thereby this study contributes to filling the research gaps and by administrative tools providing insights into the practical use of forecasting models, it guides stakeholders having to cope with the difficulties of crypto-currency markets.

Attainment of targets set to control dropout was by far behind in the government schools in Ethiopia. Thus, this study was designed in order to address student dropout experienced in the study area. The study employed mixed research method and parallel convergent design. Data were collected from students, teachers, parents and related stakeholders. The quantitative data were analyzed using mean, independent samples t-test and pearson’s correlation, whereas the qualitative ones through narration. The study revealed that the overall dropout status was moderate yet varying with the types of the community’s economic activity. Factors of dropout among the pastoralist community and that of agrarian and cash crop production areas also vary accordingly. Thus, developing community engagement project involving essential collaborators was suggested for intervening with the challenges identified. Further rigorous studies need also be conducted to intensify and scale up the impact.

historical retrospectives of the formation and activities of ethnic minority organizations in the early 1990s as one of the factors of state-building remains relevant. This study aims to analyze the historical context and peculiarities of the institutionalization of ethnic minority structures in Ukraine at the initial stage of the restoration of Ukrainian state independence. The research object is ethnic minority organizations, primarily those that focused their activities on national and cultural revival. The methodological framework includes the principles of historicism, tolerance, scientific impartiality, and impartiality. We have traced the specifics of the formation of ethnic community organizations and the main vectors of their activities during the specified period. Despite many common historical, cultural, and socio-political backgrounds, the formation of such organizations for different communities could have its peculiarities. For example, for Jewish organizations, the demographic issue was acute due to emigrant sentiments in the Jewish community. As for ethnic minorities like Hungarians and Romanians, they had close ties with their historical homelands. This fact also influenced their organizational structure in Ukraine. The Georgian minority built their organizations emphasizing cooperation between Ukraine and Georgia. Germans also sought to maintain ties with their historical homeland. For Poles, the religious factor was significant. Overall, in Ukraine, there were quite favorable conditions for the full development and activities of ethnic minorities despite the complex political and economic situation of the early 1990s. Nowadays, the issue of organizational development of ethnic communities is a matter of focus for state authorities both at the legislative level and at the level of local communities.

This investigation stems from the observed low problem-solving skills among students as indicated in prior research. The primary objective is to evaluate the impact of employing case-based learning on students’ problem-solving aptitude concerning buffer solutions. Carried out during April-May 2023, the study involved 11th-grade students at a public high school in Jakarta, Indonesia. Employing a quasi-experimental design, two classes were chosen as samples and randomly assigned roles via the flipping coin method: one as the experimental group (11 MIPA-1) and the other as the control group (11 MIPA-4), each comprising 36 students. A problem-solving assessment using an essay test featuring nine questions was administered, with the data analyzed through t-tests. The findings revealed a positive correlation between case-based learning and enhanced problem-solving skills among students in the realm of buffer solutions. In essence, the implementation of case-based learning proved effective in bolstering students’ problem-solving capabilities. Consequently, educators are encouraged to integrate the case-based learning approach to elevate students’ problem-solving proficiency across various subjects.

Published: April 2024

The preservation of historic buildings is a topic that has been explored and developed for many years with the aim of leaving a legacy for future generations. However, due to climate change, the risk of natural disasters that can result in the loss of housing, territory and historical heritage has increased exponentially. Therefore, traditional prevention and mitigation actions are not sufficient to guarantee their protection. In response to this problem, initiatives have emerged in recent years that employ technological advances, such as the virtualization of historic buildings, as a way of preserving them.
Although the virtualization of historic buildings is a relatively new methodology, its importance and application are not yet widely known. Therefore, this paper aims to publicize and highlight the importance of this technique, through the analysis of several cases of its application.
