Strategic proposals of the State Duma of the Federal Assembly of the Russian Federation in the field of higher education
Authors: Юдина О.С. , Задонская И.А.
Published: July 2024

В статье рассматриваются основные направления деятельности нижней палаты парламента в области высшего образования. Акцент делается на том, что разрабатывая стратегию в области образования, Государственная Дума ФС РФ действует в симбиозе с Президентом, Правительством РФ. До недавнего времени стратегия носила достаточно аморфный характер, а ключевыми направлениями являлась проблема финансирования отрасли образования. Современные вызова и угрозы способствовали коренному пересмотру системы высшему образования. Анализ риторики депутатов на предмет выхода из Болонской системы определяет пул мнений по дальнейшему реформированию отрасли. Подавляющая часть парламентариев при выработке стратегии нацелены на традиции и опыт, лишь некоторые из них считают о необходимости симбиоза отечественного и западного опыта.
Analisis Sistem Jaringan Tata Air Pada Lahan Rawa Pasang Surut, Desa Telang Karya, P87S, Banyuasin, Sumatera Selatan
Authors: Ma'shum Halim
Published: July 2024

The world's growing population is increasing the need for land, prompting the conversion of productive agricultural land into non-agricultural purposes. This has led to a shift in agricultural development to sub-optimal lands, such as tidal swamplands. However, several problems arise along the way, including water management. A good water management network is necessary for supporting efficient water use. This study aims to analyze the water system network on tidal swamps to support agricultural activities. The survey and field observation methods were used to collect data. The results showed that the water system in Telang Karya Village, P87S, Banyuasin, South Sumatra, experienced sedimentation in the tertiary channel. In channel 3, the thickness of sediment reached 72 cm, resulting in silting, which reduces water discharge. Field observations revealed that sedimentation occurs due to the channels being overgrown by wild plants. This hampers the water flow, causing it to slow down or even stop. In some tertiary channels, the watergate operation needs to be carried out optimally. Maintaining the ideal conditions of tertiary channels is crucial, and watergate operations should be performed based on the needs of the plants.

Published: July 2024

Machine learning (ML) models have provided a highly efficient pathway to quantum mechanical accurate reaction barrier predictions. Previous approaches have, however, stopped at prediction of these barriers instead of developing predictive capabilities in reactivity analysis tasks such as distortion/interaction-activation strain analysis. Such methods can provide insight into reactivity trends and ultimately guide rational reaction design. In this work we present the novel application of ML to the rapid and accurate prediction of distortion and interaction DFT energies across four datasets (three existing and one new dataset). We also show how our models can accurately predict on unseen, high impact literature examples where DFT-level distortion/interaction analysis has previously been used to explain reactivity trends for cycloadditions. This work thus provides support for ML to be utilised further in reactivity analysis across different reaction classes at a fraction of the cost of traditional methods such as DFT.
De-fuzzification of reflection in the education of health professionals
Authors: Schei Edvin , Fuks Abraham , Boudreau Donald
Published: July 2024

Our educational institutions are mandated to equip future physicians and other health care professionals with the scientific, craft, and inter-personal knowledge and skills to meet the demands of contemporary clinical practice. Clinicians must acquire advanced communication skills, develop the ability to manage complex situations, make appropriate use of medical knowledge and technology, and problem-solve through the exercise of refined judgment. The ability to reflect in and on situations of this nature is considered a necessary professional aptitude in order to ensure effective and compassionate whole person care. Notwithstanding the general acceptance of these premises, ‘reflection’ remains a fuzzy concept. It is a polysemous term that has proved difficult to define and has attracted to itself numerous false claims and unfulfilled promises. Excellence in reflective abilities is notoriously difficult to recognize in another individual and it may not be ‘teachable’. Furthermore, there have been recurring doubts as to the feasibility of meaningfully assessing reflection.We intend to explore these issues in this session. We will demonstrate how reflection can be role-modeled and inculcated. Instructional Methods This will be an interactive workshop. Learning Objectives     By the end of the workshop, participants will be able to:• clarify the concept of reflection and understand its application to the education of health professionals• discuss a framework, including specific methods, for the structuring and deployment of an educational program aimed at promoting reflection.

The technique for approximation of three-dimensional surfaces in order to synthesize algorithms for preventing aircraft collisions with obstacles
Authors: Vorobyev A. V. , Lelikov A. M. , Stryy V. V.
Published: July 2024

The work marks the beginning of the practical application of algorithms for making the aircraft recovery maneuver from three-dimensional constraint surfaces, which are a combination of terrain and artificial obstacles. An analysis of events leading to aviation accidents was carried out, and a comparison of on-board systems for preliminary notification of aircraft crews about collisions with natural or artificial obstacles was made. It is shown that such systems are insufficient due to their passive-recommendatory nature of issuing warnings. A question has been raised about the need to implement an active automatic collision avoidance system with spatial obstacles. In order to apply existing algorithms for the aircraft recovery maneuver from spatial constraint surfaces, a technique has been developed for approximating three-dimensional surfaces (obstacles) specified on a digital terrain map in the form of discrete height readings with a certain step on a coordinate grid. A paraboloid of revolution was chosen as a continuous 2nd order surface approximating the obstacle, and its characteristic parameters were determined. To determine the characteristic parameters of the paraboloid, an algorithm for determining the intersection of a three-dimensional surface and a plane, based on the principle of determining the intersection of triangles in space, as well as a method for selecting the inflection point of the terrain, based on determining the value of the terrain height gradient, are proposed for use. The construction of an approximating paraboloid using the example of a natural obstacle in the form of a mountain range is given. When synthesizing algorithms for preventing collisions of aircraft with obstacles, the need to take into account not only the parameters of the constraint surfaces and dynamic characteristics of aircraft, but also the accuracy characteristics of data sources about their position is noted. Promising application areas of the developed methodology are shown.

Published: July 2024

Automated Short Answer Grading (ASAG) systems contribute immensely to providing prompt feedback to students, which eases the workload of instructors. This research focuses on the development of an optimized ASAG model using LSTM model and particle swarm optimization techniques to prevent model overfitting. The popular ASAG dataset by Mohler was utilized for the experiment. The dataset contains training samples from Computer Science department of the Federal University of Technology, Minna, Nigeria, with grades between 0 and 5. In order to effectively optimize the LSTM model parameters, which are learning rate and number of neurons in the LSTM layers, four experiments were performed, each with different particle population sizes (5, 10, 15 and 20). The results show that PS5 model produced the lowest RMSE and MAPE of 0.77697 and 44.5356%, respectively. The PS15 model, however, produced the highest RMSE and MAE of 0.80985 and 56.6192%, respectively. In order to validate the developed PSO-LSTM ASAG model, normal LSTM model for ASAG was implemented and tested. The PSO-LSTM has an RMSE value of 0.77687 and MAPE of 44.5356%, as compared with LSTM, which has an RMSE value of 0.9423 and MAPE of 85.73%. The results clearly show the superiority of the developed hybrid model in predicting the scores of short answer grading. The model's performance can be further improved by increasing the sample size and using other optimization algorithms, such as genetic algorithms or ant colony optimization. Further research can also investigate the effect of other variables, such as question complexity and student writing style, on the model's performance.

Published: July 2024

Objective: To investigate the comparison of the effects of intravenous infusion of Ambroxol Hydrochloride and nebulized inhalation in the treatment of pediatric respiratory diseases. Methods: 188 children with respiratory diseases admitted to the pediatrics department of the hospital from September 2022 to March 2024 were selected as the study subjects, and were randomly divided into the control group (n = 41) and the observation group (n = 41) according to the random number table method. Both groups of patients were first treated with conventional treatment, and based on conventional treatment, the control group was treated with intravenous infusion of Ambroxol Hydrochloride, and the observation group was treated with nebulized inhalation of Ambroxol Hydrochloride. The general information, clinical symptom improvement time, oxygen therapy time, sputum aspiration frequency, hospitalization time, and the occurrence of adverse reactions were observed in the two groups. Results: The baseline data of the two groups of patients were not statistically significant (P > 0.05); the disappearance time of clinical symptoms such as cough, lung rales, and shortness of breath in the observation group was shorter than that in the control group (t = 8.739, t = 10.108, t = 19.448, P < 0.001); the time of oxygen therapy, number of sputum aspirations, and hospital stay of the patients in the observation group were significantly shorter than that of the control group (t = 10.593, t = 10.665, t = 14.673, all P < 0.001); the total incidence of adverse reactions in patients in the observation group (3/3.18%) was significantly lower than that in the control group (14/14.89%) (x2 = 7.825, P = 0.005 < 0.01). Conclusion: In the treatment of pediatric respiratory diseases with Ambroxol Hydrochloride, nebulized inhalation has better efficacy than intravenous drip, and can better improve the clinical symptoms and reduce the side effects in children.

Published: July 2024

Nanotechnology has applications in various fields of medicine. The health and biomedical fields can apply nanotechnology to treatment and drug delivery, enabling the targeted and controlled delivery of drugs and therapeutic compounds. Normally, the body quickly metabolizes drugs upon their entry, potentially affecting their efficiency. Additionally, drugs are often unable to specifically target cells, leading to harmful effects on healthy cells. Nanotechnology is currently being used to address these issues. Nanoparticles, which are tiny particles made up of either synthetic or semi-synthetic polymers, have introduced targeted drug delivery by allowing accurate and regulated secretion of therapeutic agents at specific activity sites. Their efficiency depends on features such as size, shape, surface, charge, and loading techniques. By utilizing their distinct attributes, nanoparticles can overcome biological barriers, improving the bioavailability of drugs and decreasing systemic toxicity. However, excessive use of nanotechnology also raises concerns about its potential nanotoxicity. The interaction between biological systems and nanoparticles can lead to hazardous effects such as genotoxicity, oxidative stress, inflammation, and neurotoxicity. Thus, it is important to examine the nanotoxicity of nanoparticles and develop various ways to diminish their toxic effects. This review aims to summarize the use of nanoparticles for drug delivery to specific sites, as well as their nanotoxicity.

Climate change crisis in Iraq
Authors: Anwar Nasralla Peshawa
Published: July 2024

Climate change is progressively becoming a serious and discussed issue. Besides this, there are clear evidence, observed, and confirmatory reasons for the multi-dimensional climate change impacts worldwide. Just as the countries and regions have not played an equal role in environmental pollution, heat retention, and climate change. Similarly, the effects of these phenomena are significantly different in the countries; thus, many of the main vulnerable places and others are its beneficiaries.  Apart from other fields, the areas that are heavily damaged will also be affected in terms of political geography and geopolitics. Generally, the Middle East, typically Iraq, is one of the countries that will be heavily affected by climate change. This research investigates the climate change geopolitical dimensions of Iraq using the descriptive-analytical method. The findings illustrate that present and future climate change are the provenance of many complications, including environmental, economic, and political and security, both at national and international level.

The phenomenon of substitution is one of the most important phonetic phenomena in Arabic, and much has been said about it, both ancient and modern. So I decided to write a research on it, aiming to conduct a descriptive and analytical study on the term substitution, its concept, and the method of analyzing it according to one of the commentators, namely Al-Alusi. To clarify his position on him.
We decided to limit our research to the well-known and common cases in its interpretation that occurred due to the phonetic relationship between the substitute and its substitute. So we excluded those rare cases that occur between distant sounds that do not have a phonetic vowel between them, and we limited ourselves to sounds with united exits, close ones, and in the case of not The presence of an output relationship led us towards the acoustic characteristics of the two replaced sounds.
Orientational Metaphor in Central Kurdish
Authors: Abdullah Jezhny Karzan , Faisal Aziz Srwa , Ali Kamal Dyar
Published: July 2024

This study is entitled "Orientational Metaphor in Central Kurdish". It attempts to explicate how non-spatial concepts are metaphorised in terms of various aspects of space in Central Kurdish. The main aim of the study is to interpret spatial metaphorical expressions that express the cognitive processes of meaning-making. The study adopts the Conceptual Metaphor Theory (CMT)within the framework of cognitive semantics. It deals with orientational metaphor as a specific type of conceptual metaphor. In cognitive semantics, language is a mirror of thought; linguistic expressions are manifestations of conceptual mappings structured in the mind. The data of the study is taken from ordinary everyday Kurdish. The data analysis illuminates the spatialization of a wide variety of abstract concepts through metaphorical uses of space. The study is in line with the cognitive linguists in that linguistic expressions that represent concepts are not semantically independent, as the Anglo-American philosophical tradition claimed, but are structured with respect to one another. Spatial concepts are first structured in thought in the form of a formula based on physical and socio-cultural experiences, and then expressed via linguistic metaphors; accordingly, metaphor is a cognitive phenomenon, it is in thought, not in language. It is patterns of thought that are echoed in patterns of language.
A Prey-Predator Mathematical Model With Diffusion and Home Ranges
Authors: Alanazi Khalaf M.
Published: July 2024

A prey-predator model with diffusion and home ranges is considered. The model consists of partial differential and integral equations. The model incorporates complex mathematical expressions, which make it hard to analyze mathematically. Therefore, a numerical solution is provided in two cases. The first case considers the prey population growing logistically, while we consider the exponential growth of the prey population in the second case. We study the dynamic behavior of the two species for both cases. Special attention goes to the impact of home ranges and diffusion coefficients on the dynamics of prey and predator populations.
THE HERO UNDER THE WALLS OF THE FORTRESS. ON THE QUESTION OF THE VISUAL REPRESENTATION OF RAMESSES II IN THE BATTLE OF KADESH
Authors: Reunov Yury S. ,   Russian Academy of Sciences Centre for Egyptological Studies
Published: July 2024

The Ramesseum temple erected under Ramesses II is one of the most significant monuments of Egyptian architecture of the XIX dynasty. Battle scenes illustrating the last major battle of the Bronze Age – the Battle of Kadesh – have been preserved on its walls. The fierce opposition of the young Pharaoh to the Hittites led to the signing of the first peace treaty in history. In Egyptian sources, Ramesses appears as a victor who prevailed over the enemy, thanks to his personal qualities and the will of the gods. The comparison of written evidence and relief images allows us to form an objective vision of the battle of Kadesh, its course and results. The analysis of sources also makes it possible to identify specific features of Egyptian official art, which include the canonical rules for the image presentation of the victorious king, as well as the artistic techniques used for that. Special attention is paid to the context of the creation of reliefs, namely, the state ideology and worldview of the ancient Egyptians in the era of the New Kingdom.

Convex Roman Dominating Functions on Graphs under some Binary Operations
Authors: Fortosa Rona Jane Gamayot , Jamil Ferdinand , Canoy Sergio
Published: July 2024

Let $G$ be a connected graph. A function $f:V(G)\rightarrow \{0,1,2\}$ is a \textit{convex Roman dominating function} (or CvRDF) if every vertex $u$ for which $f(u)=0$ is adjacent to at least one vertex $v$ for which $f(v)=2$ and $V_1 \cup  V_2$ is convex. The weight of a convex Roman dominating function $f$, denoted by $\omega_{G}^{CvR}(f)$, is given by $\omega_{G}^{CvR}(f)=\sum_{v \in V(G)}f(v)$. The minimum weight of a CvRDF on $G$, denoted by $\gamma_{CvR}(G)$, is called the \textit{convex Roman domination number} of $G$. In this paper, we specifically study the concept of convex Roman domination in the corona and edge corona of graphs, complementary prism, lexicographicproduct, and Cartesian product of graphs.
Deformations in translating modern Ukrainian war fiction into English – A psycholinguistic study of "Інтернат"/The Orphanage by Serhiy Zhadan
Authors: Kalishchuk Diana , Zasiekin Serhii
Published: July 2024

The article is focused on analysing linguistic deformations in translating modern Ukrainian war fiction into English. The research material is the novel "Інтернат"/ The Orphanage by Serhiy Zhadan and its translation into English. Translation deformations, or "deforming tendencies" (Berman, 2000), are viewed as systemic psycholinguistic distortions, arbitrary and non-arbitrary, of formal and content source text characteristics. Three main groups of translation deformations have been identified in the text under analysis - lexical, stylistic, and grammatical. Lexical deformations include calque translation, concretisation and modulation. Due to their low frequency, they are not viewed as typical. Stylistic deformations fall into synonymous substitution, logisation, explication, expressivation, modernisation, antonymous translation, and compensation. Synonymous substitution and logisation are the most frequent types; therefore, they may be considered prototypical. They are mainly concerned with reproducing characters’ names and descriptions, names or descriptions of military and civil vehicles and tools, colloquial expressions and 'surzhyk'. Grammatical deformations constitute the most significant group. They comprise substitutions and permutations of different types, deletion of words/phrases/sentences, addition of words/phrases, and changes in punctuation. The style of Serhiy Zhadan is characterised by specific syntactical-stylistic features, such as the tendency to use extremely long sentences, high frequency of repetitions of different types, and specific punctuation. Therefore, deleting repetitions, intensifiers, discourse markers, and even sentences is the most recurrent type of grammatical deformation, followed by substitution–division of sentences, which may be treated as prototypical grammatical deformations in the analysed text.

Authors: Pachano Peláez Karen , Duarte Ballesteros Miguel , Altamar Mercado Hernando , Piedrahita Escobar Carlos , Salinas Garnica Trino , Calderón Carrillo Zuly
Published: July 2024

This paper presents some fundamental concepts of seismic anisotropy specifically those which have hexagonal symmetry (ordinarily called transversely isotropic in geophysics jargon). There were made calculations of phase and group angles at a planar interface separating an anisotropic media, using routines written in Matlab ® and Maple ® language. The slowness surfaces of the qP, qSV and SH wave, as well as the ray paths in these two media were also estimated. Although only the simplest situations are discussed, this paper is useful as a first step in understanding the fractured media, because it contains examples, software routines, and a reviewing of the basic concepts and formulas of wave propagation.
Capillarity and rapid flow effects on gas condensate well tests
Authors: Cantillo José Humberto , Escobar Freddy Humberto , Muñoz Oscar Fernando
Published: July 2024

The state-of-the-art of gas condensate well tests for pressures below the dewpoint are basically based upon a two-zone composite radial model, which consists of a near-wellbore region having liquid condensation and a monophasic flow zone with no gas condensate saturation. Information obtained from laboratory tests suggests the presence of three zones having different fluid mobilities: (1) a far region from the well with initial liquid condensate saturation of zero, (2) a near wellbore zone having an increased condensate saturation and a reduced gas mobility, and (3) an intermediate zone from the well with both high capillary and increasing gas relative permeability which leads to gas mobility restoring due to condensate blocking. The gas condensate saturation is higher than its critical value, then the condensate phase is mobile. In this study, both the rapid flow and capillary number effects on gas condensate reservoirs from well pressure test data are dealt with. We observed that the nondarcy effect originates additional pressure drop which is proportional to the flow rate while, the capillary number causes a reduction of condensate saturation in the near wellbore area and the reservoir providing a negative skin factor which contributes to fluid mobility, and therefore, production. Besides that, we also included the possitive coupled effect, defined here as the simoultaneous action of nondarcy flow and capillary number; which is more relevant at relatively low gas rates. We found out that the capillary number dominates the nondarcy effect leading to a reduction in condensate saturation.
Effect of well stimulation on the skin factor in elongated reservoirs
Authors: Escobar Freddy Humberto , Montealegre M. Matilde
Published: July 2024

Because of fluvial deposition or faulting, many reservoirs around the world may possess a long and narrow geometry in which linear flow is expected to take place once radial flow vanishes, if existed. In any system through which a fluid flows, a change in the path direction causes additional pressure drop. Hydrocarbon reservoirs are not the exception to the rule. A change from radial flow to linear flow will be reflected as an additional pressure drop which may be referred as a skin factor, or more specifically, a geometric skin factor. A couple of studies in the oil literature have named skin factors due to the change in flow patterns. Besides this, most of the commercial softwares may neither include nor calculate these types of skin factors since the simulations are normally run using the image methods, then, skin factors due to changes in flow path may be neglected.  Using the only methodology available to estimate the linear skin factors, it has been found from the experience on some field cases that this parameter is quite high in some cases and very small in other systems. Therefore, this paper is committed to the determination of the factors affecting the value of the linear skin factor and their impact on reservoir management. It was found that neither reservoir permeability nor reservoir elongation had a significant impact on the linear skin factor value; however, the well stimulation does play an important role. The more damaged the well, the higher the linear skin factor value. From our simulation study, we found out that no matter if the well has a zero mechanical skin factor, still the linear skin factor has a high value. Besides, we demonstrated that the total skin factor increases as the linear skin factor increases with a ratio of 2,7385: 1,7385. Two Colombian field cases were worked with the purpose of verifying the findings of this article.
Conventional analysis for characterization of bi-radial (elliptical) flow in infinite-conductivity vertical fractured wells
Authors: Cantillo José Humberto , Escobar Freddy Humberto , Montealegre M. Matilde
Published: July 2024

It is difficult to ignore a 0,36-slope line, bi-radial flow, which shows up in the pressure derivative plot of many well pressure tests conducted in hydraulically fractured vertical wells. Needless to say that interpretation of this flow regime as linear flow introduces errors in the estimation of the fracture parameters. Very few technical papers have dealt with the bi-radial or elliptical flow. Even though, none of the commercial well test interpretation packages name it, they can reproduce the typical pressure behavior in which elliptical flow is seen. For more than half a century, conventional techniques have been a very reputed and respected method for interpretation of well pressure tests. Therefore, it is necessary to add a new methodology to complement the conventional technique so that the bi-radial/elliptical flow can be characterized, and of course, its application leads to an appropriate evaluation and assessment of a fracture treatment. Therefore, this paper provides a new alternative which allows to obtain the slope of the cartesian plot of pressure vs. either t 0,36 (for drawdown) or ([ t p +?t ] /?t ) 0,36 (for buildup) from which the half-fracture length is readily estimated. The proposed technique was verified by the application of a field case and a simulated example.

The Government Regulation No. 48 of 2014 concerning Tariffs for Non-Tax State Revenues that apply to the Ministry of Religion, among others, stipulates that the cost of registering marriages performed at the religious affairs office (RAO) on working days and hours is zero rupiah (free), whereas if a married is performed at home, it is subject to a fee of IDR 600,000. In fact, many people still perform marriages at home. Against this phenomenon, there are two interesting problems to study. First, how is public knowledge about the Government Regulation No. 48 of 2014? Second, what are the reasons beyond people's preferences for marriages at home instead of at RAO? This study belonged to empirical socio-legal research in the form of field research and applied a qualitative descriptive analysis method. The conclusion of this study fell into two. First, there were still many people who did not know and understood the Government Regulation No. 48 of 2014. The things that underlined people's preferences for marriages at home entailed views and beliefs of the marriage sacredness, tradition or custom, self-respect, avoiding negative images, limited RAO’s facilities, convenience, the distance of RAO, and time efficiency.

Religious moderation is one of the teachings of Islam as stated in the Qur'an. It should be noted that moderation is a middle attitude without discrimination, intervention or one-sidedness which contains moderate, fair and balanced ideas in all aspects of life, whether religious, social, educational, cultural, and others. Moderate attitudes are important to instill in the nation's generation as early as possible. Given that Indonesia is a country whose society is plural and multicultural, it is not surprising that there are diverse differences. Moderate attitudes need to be instilled to maintain the integrity of relationships both individually, in groups and in the state. Recently, Indonesia has been bombarded with issues about religion, such as blasphemy, hate speech, discrimination of minority communities, extreme groups and others. With this, it certainly threatens the integrity and peace in Indonesia. An alternative path that can be used is through Islamic education. Islamic education is a relevant early solution to understand the meaning of tolerance, justice, harmony, balance and love of peace. This research will explain the meaning of religious moderation using descriptive qualitative methodology with library research studies sourced from books, journals and the Qur'an. The results of this study indicate that there is a development in terms of human character to become a moderate and reactive human being.
