Authors: AL-Dulaimi Ali M. , Al- Shammaa Ayser M.
Published: October 2023

One of the primary goals of any study involving groundwater is to make an exact assessment of the physical properties of the layers containing the water. One of the most fruitful ways to approach this goal is to conduct a pumping test for the aquifer. To make the most use of groundwater in terms of sustainable water management, this study attempts to assess its hydraulic features relative to the most significant aquifer represented in the Euphrates formation. A pumping test was carried out on 6 wells where each well is accompanied by an observation well. Cooper-Jacob and Theis Recovery methods were used to determine the aquifer transmissivity and storage coefficient. The ranges for permeability, transmissivity, and specific yield are (0.42 - 3.05 m/day, 13.89 -76.47 m2/ day, and 0.018 - 0.036) respectively, whereas, calculated transmissivities based on specific capacity showed a wide range from 30.85 m2/day to 120.96 m2/day. This wide range reflects the complex lithology of the aquifer, which was influenced by structural elements including stress and joint density.
Impact of Heat Transfer and Inclined MHD on A Non-Uniform Inclined Asymmetrical Channel with Couple Stress Fluid Through A Porous Medium
Authors: Abdulhussein Hanaa , Abdulhadi Ahmed M.
Published: October 2023

The goal of this study is to investigate the effects of heat transfer on a non-uniform inclined asymmetrical channel with couple stress fluids via a porous medium using incline magnetohydrodynamics. The governing equation is studied while using low Reynolds approximations and long-wavelength assumptions. Mathematical expressions for (pressure gradient), (temperature), (axial velocity), (heat temperature coefficient), and (stream function). A precise set of values for the various parameters in the present model has been used. The mathematical expressions for axial velocity, stream function, pressure gradient, and pressure rise per wavelength have been derived analytically. "MATHEMATICA" is used to present the computational results in the form of graphs. It has been noticed that both the pressure rise and the pressure gradient decrease with the rise of the inclination magnetic field angle and Darcy number, while as the Grashof number increases, the pressure gradient reduces and the pressure also increases. According to this study, the heat transfer coefficient and temperature rise when the Brinkman number and the Hartman number are up. As the Hartman number and couple stress increase, the incidence of trapped boluses diminishes in size and vanishes in the direction downstream. The bolus size can also be increased by raising the non-uniform channel's Darcy number.
A New Efficient Hybrid Approach for Machine Learning-Based Firefly Optimization
Authors: Alsoul Mohamed , Zaher Hegazy , Ragaa Naglaa , Oun Eyman Mostafa
Published: October 2023

Optimization is the task of minimizing or maximizing an objective function f(x) parameterized by x. A series of effective numerical optimization methods have become popular for improving the performance and efficiency of other methods characterized by high-quality solutions and high convergence speed. In recent years, there are a lot of interest in hybrid metaheuristics, where more than one method is ideally combined into one new method that has the ability to solve many problems rapidly and efficiently. The basic concept of the proposed method is based on the addition of the acceleration part of the Gravity Search Algorithm (GSA) model in the Firefly Algorithm (FA) model and creating new individuals. Some standard objective functions are used to compare the hybrid (FAGSA) method with FA and the traditional GSA to find the optimal solution. Simulation results obtained by MATLAB R2015a indicate that the hybrid algorithm has the ability to cross the local optimum limits with a faster convergence than the luminous Fireflies algorithm and the ordinary gravity search algorithm. Therefore, this paper proposes a new numerical optimization method based on integrating the properties of the two methods (luminous fireflies and gravity research). In most cases, the proposed method usually gives better results than the original methods individually.

Image Compression Using Mapping Transform with Pixel Elimination
Authors: Kamatar Vishwanath S. , Baligar Vishwanath P.
Published: October 2023

In today's world, digital image storage and transmission play an essential role,where images are mainly involved in data transfer. Digital images usually take large storage space and bandwidth for transmission, so image compression is important in data communication. This paper discusses a unique and novel lossy image compression approach. Exactly 50% of image pixels are encoded, and other 50% pixels are excluded. The method uses a block approach. Pixels of the block are transformed with a novel transform. Pixel nibbles are mapped as a single bit in a transform table generating more zeros, which helps achieve compression. Later, inverse transform is applied in reconstruction, and a single bit value from the table is remapped into pixel nibbles. With these nibbles, pixel values of the block are reconstructed without any loss. The average method is used in reconstruction of excluded pixels. This approach achieves better quality in reconstructed test images at lower PSNR values ranging from 33dB to 44dB. Compression ratio achieved is more than 2. Correctness ratio achieved by proposed method is more than 0.5.
Comparing the Random Forest vs. Extreme Gradient Boosting using Cuckoo Search Optimizer for Detecting Arabic Cyberbullying
Authors: Saadi Marwa Q. , Dhannoon Ban N.
Published: October 2023

Cyberbullying is one of the major electronic problems, and it is not a new phenomenon. It was present in the traditional form before the emergence of social networks, and cyberbullying has many consequences, including emotional and physiological states such as depression and anxiety. Given the prevalence of this phenomenon and the importance of the topic in society and its negative impact on all age groups, especially adolescents, this work aims to build a model that detects cyberbullying in the comments on social media (Twitter) written in the Arabic language using Extreme Gradient Boosting (XGBoost) and Random Forest methods in building the models. After a series of pre-processing, we found that the accuracy of classification of these comments was 0.861 in XGBoost, and 0.849 in Random Forest. Then the results of this model were improved by using one of the optimization algorithms called cuckoo search to adjust the parameters in two methods. The results are improved clearly in the random forest method, which obtained results similar to the extreme gradient boosting method, with a value of 0.867.

Published: October 2023

The current study aimed to synthesize silver nanoparticles (Ag NPs) in a safe and eco-friendly biological method using green tea extract, characterize them using UV-vis spectroscopy, FTIR, XRD, FESEM, and AFM tools, then investigate their antioxidant potentials against DPPH and their cytotoxicity toward lymphoma cells using MTT and ethidium bromide/propidium iodide dual staining assays, and their genotoxic capacities by assessing their effects on the gene expression of p53, caspase3, bcl-2, and bax genes by qPCR and DNA fragmentation.  Results confirmed the synthesis of silver nanoparticles; the UV-vis results showed a peak of absorbance at 414 nm; FTIR analysis showed absorbance belonging to the functional groups of green tea; XRD assay results confirmed the crystallinity of Ag NPs; and AFM revealed a mean diameter of around 24.37 nm. Finally, FESEM showed that the shape of Ag NPs was that of spherical aggregated nanoparticles. The synthesized nanoparticles showed antioxidant activity and cytotoxic effects against lymphoma cells, with an IC50 =  1.138 μg/ml. Cell staining results showed alternations in the shape of treated cells due to apoptosis. Ag NPs affected gene expression as they increased proapoptotic genes p53, caspase3, and bax by 3.3, 2, and 4.25fold, respectively, while decreasing antiapoptotic gene expression bcl-2 by 0.59fold. We concluded that the biological way is an efficient way to synthesize silver nanoparticles, and the synthesized NPs have antioxidant potential and are cytotoxic and genotoxic toward lymphoma cells; thus, they may be utilized in related biomedical applications.

O transtorno depressivo maior (TDM) é uma entidade complexa e multifatorial de duração estabelecida, associada a sintomas como tristeza, anedonia e o aumento ou a perda de peso e apetite. Alterações de hábitos nutricionais são frequentes em indivíduos acometidos, agravando a evolução e o prognóstico da doença. Os objetivos deste estudo são conhecer as relações entre hábitos nutricionais e o desenvolvimento do TDM, a função dos nutrientes na manutenção da saúde mental e os grupos alimentares que os representam. Foi realizada uma revisão de literatura por meio da análise de 20 artigos acerca do tema, publicados nos últimos 10 anos. Os resultados das análises evidenciaram que indivíduos acometidos pelo TDM possuem padrão alimentar irregular, dando preferência a alimentos ultraprocessados, o que desencadeia uma série de alterações intimamente ligadas à patogenia da doença. A dieta mediterrânea segue como principal modelo intervencionista, entretanto, os estudos são inconclusivos a respeito da relação causal entre má nutrição e depressão, sendo necessárias novas abordagens metodológicas.

Published: October 2023

A vitamina D está envolvida em diversos processos fisiológicos dentre homeostase óssea e o sistema imunológico. Pesquisas recentes têm discutido os múltiplos efeitos da vitamina D também como anti-inflamatória e antiviral em várias doenças infecciosas, como a COVID-19. A busca por recursos terapêuticos adjacentes capazes de prevenir e/ou tratar a COVID-19 tem estimulado estudos acerca do papel da vitamina D na infecção por SARS-CoV-2. Neste presente trabalho, os papéis imunomoduladores, antivirais e anti-inflamatórios da vitamina D requerem uma investigação completa, particularmente na perspectiva da COVID-19. Objetivo: Esta revisão tem por objetivo selecionar e sintetizar as evidências atuais da literatura sobre a suplementação da vitamina D em pacientes diagnosticados com COVID-19. Metodologia: Este trabalho foi conduzido de acordo com as diretrizes do protocolo PRISMA. No total 21 artigos selecionados atenderam aos critérios de inclusão e exclusão estabelecidos. Para esta revisão, pesquisamos os bancos de dados PubMed, Embase e BVS (Biblioteca Virtual de Saúde). Estudamos vários estudos observacionais e ensaios clínicos randomizados avaliando o papel da vitamina D na COVID-19 e outras infecções virais contagiosas. Também revisamos as evidências circunstanciais e anedóticas que conectam a vitamina D a COVID-19 que surgiram recentemente. Resultados: A maioria dos estudos mostram associação entre baixos níveis séricos de vitamina D e o aumento da gravidade e da mortalidade da COVID-19. Apenas 4 estudos não demonstraram haver associação entre os níveis basais de calcidiol e o desfecho da COVID-19. Conclusão: Embora as evidências disponíveis até o momento apontem possível efeito protetor da vitamina D nas internações em UTI relacionadas a doença causada por Sars CoV-2, ainda são necessários estudos clínicos controlados bem desenhados para validar a dose e a eficácia da suplementação de vitamina D na COVID-19 e em outras infecções virais.

A unified reference system for geometric characteristics is based on the classification of joints of applied mechanics, in which the class number is determined by the number of degrees of freedom limited by mating elements of parts and has received the short term «informativeness». Different information content of the bases of elements that materialize coordinate systems determines different information content of the coordinate axes – four, two, zero and different information content of design planes – three, two, one. The paper shows that the information content of elements in the functions of auxiliary bases and executive elements determines the number and type of coordinates (linear and angular), with the help of which it is necessary to set their position in the generalized coordinate system of the part. It is shown that the accuracy of coordinating dimensions should be specified by symmetrical tolerances for linear and angular dimensions.

To determine the composition of inhomogeneous samples using the method of laser-spark emission spectrometry, calibration dependences are used, which can have significant systematic errors that significantly affect the determination of the quantitative composition of elements. Sample inhomogeneity also causes inaccuracies in replicate measurements. To reduce errors, multi-signal calibration and internal standard methods are used, which can significantly improve accuracy when changing experimental conditions and eliminate the need to purchase ex-pensive standard samples.

The paper considers the shaping of cyclic surfaces based on nonlinear rotation, in which the axis of rotation and the generatrix in the general case are three-dimensional smooth curves. As a tool for shaping surfaces of non-linear rotation, the method of the accompanying Frenet trihedron, known in the differential geometry of curved lines, is used. The geometric scheme of surface shaping is based on a construction that includes: a curvilinear axis of rotation and a one-parameter set of its normal planes; a generatrix whose points describe in normal planes circular trajectories centered on a curvilinear axis. A mathematical model of shaping the surface of non-linear rotation for the general case of specifying the axis of rotation and the generatrix is given. On the basis of this model, test examples of the formation of surfaces of nonlinear rotation, which are cyclic surfaces, each of which accompanies the corresponding nonlinear quadric of rotation, are considered. In the examples of shaping, the original rectilinear axis of a non-linear quadric of revolution and its generating line, a second-order curve, are functionally interchanged: the secondorder curve becomes the rotation axis, and the rectilinear axis becomes the generatrix. The resulting family of surfaces of non-linear rotation belongs to the well-known class in the theory of analytic surfaces "Normal cyclic surfaces". It complements this class and fundamentally differs in the method of shaping.

The paper develops an algorithm for determining the required diagnostic parameters and performance indicators of mobile power equipment (MPE), which implements the methodology improved by the authors of the non-brake studies of the internal combustion engine (ICE) and moving MPE during the transient process of their acceleration. For the first time, the regularity of recording, processing data from primary converters and the sequence of calculating model parameters is shown, with the possibility of taking into account the characteristics of the transient processes of acceleration of the crankshaft of the internal combustion engine and the MPE, Thus, the developed algorithm and software structure are able to implement the methodology proposed by the authors of the non-standard studies of the internal combustion engine (ICE) and the moving MPE. To fix the required parameters from the primary converters, it is proposed to use the well-known programs CoolEdit2000 v.1.0.2374 and VisualGPS v.4.2.105.1. The article describes in detail each process of the algorithm, reflects the procedure for working with primary information and ways to improve the accuracy of calculations.

The article is devoted to the development and analysis of a model of the motion of a micropolar lubricant in the working gap of a radial plain bearing with a fluoroplastic-containing antifriction composite polymer coating and with a groove on the supporting surface. New models are obtained on the basis of classical equations in the «thin layer» approximation and the continuity equation, which describes the turbulent mode of motion of a lubricant with micropolar rheological properties. The results of the numerical analysis of the obtained models of existing operational characteristics made it possible to obtain a quantitative assessment of the effectiveness of the support profile with a fluoroplastic-containing antifriction composite polymer coating with an axial groove. To complete the complex of studies and verify theoretical developments, experimental studies are carried out. The novelty of the work lies in the concretization of the technique of engineering calculations for the design of an effective radial bearing with an antifriction polymer coating with an axial groove on the bearing surface of the bearing bush, taking into account the dependence of the rheological properties of a micropolar lubricant on pressure and temperature in a turbulent mode, which makes it possible to estimate the value of the main operational characteristics: hydrodynamic pressure, load ability and coefficient of friction, as well as to expand the scope of practical application of models for engineering calculations. Thus, the design of a radial bearing with a polymer-coated support profile, a groove 3 mm wide, ensured a stable ascent of the shaft on a hydrodynamic wedge, which experimentally confirmed the correctness of the results of theoretical studies of a radial bearing with a diameter of 40 mm at a sliding speed of 0,32–3 m/s, load 4,9–24,5 MPa.

The article is devoted to the study of specific kinematic pairs used in many areas of mechanical engineering: the so-called «rolling pairs» used in many mechanisms. The study is based on a detailed study of the structure of the «cylinder in cylinder» connection, and their geometric parameters are considered. The analysis is considered by the location of the axes of the cylinders between themselves: when the axes are parallel and when they intersect or intersect at an angle of 90 º. This study complements the data in the theory of description of kinematic pairs, in particular, rolling pairs, and makes it possible to synthesize their new types for their rational use in the mechanisms of many industries.

Improving the reliability and increasing the operational life of electrical equipment of electric rolling stock is one of the eight directions of scientific and technical development of JSC «Russian Railways» described in the target program «Strategy for the development of railway transport in the Russian Federation until 2030», approved by the decree of the Government of the Russian Federation. The solution to the problem of improving operational reliability is associated with comprehensive measures that include a wide range of issues aimed at ensuring the stable operation of rolling stock and its systems. Reliable operation of electric machines, which depends on the quality of repairs, has a significant impact on the operational reliability of electric rolling stock.

An inventory of the fossil taxonomic composition of the extinct freshwater Alveolophora Moisseeva et Nevretdinova in the Neogene deposits of Southern Primorsky Krai has been carried out. The study of the valves using scanning electron microscopy signifi cantly changed the conclusions of previous researchers. Only two species were found in the studied deposit, A. khursevichiae Usoltseva, Pushkar et Likhacheva in the Middle Miocene and A. tscheremissinovae Khursevich in the Middle Miocene and Pliocene, instead of the four previously indicated. The descriptions of A. tscheremissinovae have been amended. It has been established that these taxa never occur together in fossil communities, which led to the conclusion about their diff erent ecological tolerance. The relatively narrow stratigraphic distribution of the taxa allows for using them as indicator species for the age of the deposits. That information can be used to update the diatom zonal scheme of the Neogene in Primorsky Krai.

Реабилитация спортсменов после получения травмы ограничивает не только дальнейшее их участие в соревновательной деятельности, но также и снижается общее качество жизни. В связи с этим, процесс восстановления является важнейшей характеристикой и построение восстановительных графиков позволяет определить наиболее перспективные технологии восстановления и меры, способствующие достижению ранее показываемых результатов. Новизна исследования определяется возможностями достижения ранее показываемых результатов с использованием методологии полного восстановления. Вместе с тем, авторы отмечают, что помимо физиологического восстановления существует необходимость в достижении морального и этического компонент. Компонент подобного толка определяется как способность спортсмена к фильтрации поступающей информации и снижению внимания на отвлекающие элементы, которые называются белым шумом и носят не только технический эффект. Авторы показывают, что это позволяет сократить время восстановительного периода и увеличить сроки выступления спортсмена в последующих соревновательных периодах. Практическая значимость исследования определяется динамикой восстановления спортсмена и применением модели фильтрации окружающей информации. Определено, что структура мониторинга является решением системы входа и выхода, что позволяет обеспечить интерпретацию необходимой информации.

Rehabilitation of athletes after injury restricts not only their further participation in competitive activities, but also reduces the overall quality of life. In this regard, the recovery process is the most important characteristic and the construction of recovery schedules allows you to determine the most promising recovery technologies and measures that contribute to achieving previously shown results. The novelty of the study is determined by the possibilities of achieving previously shown results using the methodology of full recovery. At the same time, the authors note that in addition to physiological recovery, there is a need to achieve moral and ethical components. A component of this kind is defined as an athlete's ability to filter incoming information and reduce attention to distracting elements, which are called white noise and have not only a technical effect. The authors show that this makes it possible to shorten the recovery period and increase the timing of the athlete's performance in subsequent competitive periods. The practical significance of the study is determined by the dynamics of the athlete's recovery and the use of a model of filtering environmental information. It is determined that the monitoring structure is the solution of the input and output system, which allows for the interpretation of the necessary information.

Модель подготовки преподавательского состав для работы в школе предполагает наличие не только уже утвержденного инструментарий оценки качества образования, но также и формирования принципов обучения. Для этой цели задействуется структура интегрированного образования, которая формирует возможность целостного познания окружающего мира для школьников и применения технологий для устойчивого образования на стороне преподавателя. Новизна исследования определяется тем, что интегрированное обучение может быть задействовано не только в границах обучения будущих преподавателей, но прежде всего возможности применения принципов интегрированного обучения для школьников. Авторы показывают, что интегрированное обучение может быть реализовано только при подготовке самих младших школьников и выявления у них собственного мышления и стремления к познанию. В статье определяется возможность использования методического комплекса, который будущий учитель может применять для работы со школьниками и ценностные установки, которые в последующем формируют уже стремление школьников к обучению. Практическая значимость исследования определяется тем, что использование методики интегрированного обучение позволяет расширить педагогические приемы и в старшей школе использовать их уже нативно.

The model of training the teaching staff to work at the school assumes the presence of not only the already approved tools for assessing the quality of education, but also the formation of learning principles. For this purpose, the structure of integrated education is used, which forms the possibility of a holistic knowledge of the surrounding world for schoolchildren and the use of technologies for sustainable education on the teacher's side. The novelty of the research is determined by the fact that integrated learning can be involved not only within the boundaries of the training of future teachers, but above all the possibility of applying the principles of integrated learning for schoolchildren. The authors show that integrated learning can be implemented only when preparing the younger students themselves and revealing their own thinking and desire for knowledge. The article defines the possibility of using a methodological complex that a future teacher can apply to work with schoolchildren and value attitudes that subsequently form the desire of schoolchildren to learn. The practical significance of the study is determined by the fact that the use of the integrated learning methodology allows you to expand pedagogical techniques and use them natively in high school.
