Authors: OCAKCI Ebru , SAMANCI Osman
Published: March 2024

In this study, it is aimed to develop the “Social Studies Course Engagement Scale” to be used for 4th grade elementary school students. Despite the critical importance of the engagement for the social studies course, no engagement scales developed specifically for the social studies course were found in the literature. A total of 730 4th grade elementary school students were included in the development of the scale. As a result of “exploratory factor analysis”, a scale structure consisting of 12 items and 2 sub-dimensions was created. It was determined that the created structure explained a total variance of 51.62%. The first dimension of the scale, individual engagement, helped explain 39.90% of the total variance, while the second dimension, interaction engagement assisted in clarifying 11.72% of the total variance. As a result of “confirmatory factor analysis”, it was determined that the structure of the scale was adequate. The reliability of the scale was analyzed using “Cronbach's Alpha”, “McDonald's Omega” and test-retest reliability coefficients were used. Both “Cronbach's Alpha” and “McDonald's Omega” coefficients were calculated as 0.81. Test-retest reliability coefficient was calculated as 0.72. It was determined that the “Social Studies Course Engagement Scale” is a reliable and valid measurement tool.

Published: March 2024

The classification problem is one instance of a problem that is typically handled or resolved using machine learning. When there is an imbalance in the classes within the data, machine learning models have a tendency to overclassify a greater number of classes. The model will have low accuracy in a few classes and high accuracy in many classes as a result of the issue. The majority of the data has the same number of classes, but if the difference is too great, it will differ. The issue of data imbalance is also evident in the data on lung cancer, where there are 283 positive classes and negative classes 38. Therefore, this research aims to use a hybrid sampling technique, combining Synthetic Minority Over-sampling Technique (SMOTE) with Edited Nearest Neighbors (ENN) and Random Forest, to balance the data of lung cancer patients who experience class imbalance. This research method involves the SMOTE-ENN preprocessing method to balance the data and the Random Forest method is used as a classification method to predict lung cancer by dividing training data and testing 10-fold cross validation. The results of this study show that using SMOTE-ENN with Random Forest has the best performance compared to SMOTE and without oversampling on all metrics used. The conclusion is using the SMOTE-ENN hybrid sampling technique with the Random Forest model significantly improves the model's ability to identify and classify data.

Elena Garro y Gabriel García Márquez: entre el Boom y la domesticidad
Authors: Santaolalla González Silvia
Published: March 2024

El Boom latinoamericano fue uno de los movimiento literarios más importantes del siglo xx para los escritores de América Latina, sin embargo, grandes figuras literarias femeninas fueron invisibilizadas y menospreciadas tanto por la academia como por las editoriales en contraposición con sus contrapartes masculinas. El siguiente artículo se centra en dos escritores: Elena Garro y Gabriel García Márquez, para mostrar que fue su contexto sociocultural y no una disparidad en la calidad de sus obras el cual creó las diferencias de recepción entre ambos autores. A través del análisis comparativo de sus aportaciones literarias, así como del contexto en el que ambas obras fueron escritas, se podrá comprender la importancia de revalorizar la obra de las autoras del siglo XX.

Published: March 2024

The management of paraoesophageal hernia has been a subject to significant debate, particularly regarding the timing and approach of surgical intervention.
Objective — to compare postoperative outcomes between Nissen and Dor fundoplication techniques for treating paraoesophageal hernias.
Materials and methods. A prospective study was conducted at the Ivano‑Frankivsk Regional Hospital from March 2018 to January 2023, involving 106 patients undergoing either Nissen or Dor fundoplication. Inclusion criteria were patients 18 years or older with paraoesophageal hernias requiring surgery. Exclusions were previous esophageal or gastric surgery, esophageal motility disorders, or contraindications to general anesthesia or laparoscopic surgery. Follow¬up assessments were conducted at 1 and 3 months post‑surgery and included dysphagia rate, need for proton pump inhibitors, comorbidity profiles, duration of surgery, and hospital stay.
Results. Both groups were comparable in terms of age, gender, body mass index, and preoperative symptoms, ensuring a fair comparison of surgical outcomes. The Nissen procedure showed a trend towards longer operative times and hospitalization duration, which could be attributed to its technical complexity. The Dor fundoplication group exhibited a more significant reduction in dysphagia symptoms postoperatively. This finding suggests better management of this specific complication compared to the Nissen group. A notable decrease in the need for proton pump inhibitors was observed in the Dor group, indicating more effective control of acid reflux symptoms.
Conclusions. Dor fundoplication is associated with less severe postoperative dysphagia and reduced need for proton pump inhibitors compared to Nissen fundoplication. Additionally, Nissen fundoplication tends to involve longer operation times and hospital stays, indicating higher complexity. The study highlights the impact of fundoplication type on postoperative outcomes in paraoesophageal hernia patients.
The role of age and other factors in the development of taste disorders
Authors: Emelyanova N. Y.
Published: March 2024

The study of the physiology of taste and its relationship to human health is gaining increasing attention. Taste sensitivity is an important tool in the regulation of nutrient intake, in the control of digestion, and in the release of neuroendocrine hormones of hunger and satiety. It is well known that many bodily functions deteriorate with age, including oral functions. The search was carried out in the medical databases PubMed, MEDLINE, Google Scholar. The article discusses age‑related decline in taste sensitivity, which is associated not only with a decrease in the number of taste receptors, but also with insufficient saliva production, which leads to a temporary delay in the turnover of taste receptor cells, which significantly increases the response of taste cells. Changes in the inorganic composition of saliva, leading to fluctuations in salivary pH, may explain its effect on receptor stimulation, which indirectly affects the perception of sweet in the elderly. We also present data from studies of non‑genetic factors, such as the gut and oral microbiota, for their potential role in modulating receptor abundance and, in fact, taste perception. Taste buds face the unique challenge of dealing with pathogens entering the oral cavity without a strong physical barrier. On the one hand, the presence of commensal microbes in close proximity to taste‑sensitive cells provides modulation around the receptor concentration of substances/compounds, which can lead to changes in taste perception. On the other hand, the accumulation of microbial plaque probably blocks the taste pores and prevents access to the receptors. Understanding these changes is the first step to maintaining oral health as you age.
Current insights into microbiome-based therapy. Review
Authors: Tkach S. M. , Dorofeyev A. E. , Ryzhii L. M.
Published: March 2024

Over the past decades, it has become apparent that a human body is inextricably intertwined with the microbiome. The latter exchanges metabolites with a host’s organism, protects it from infectious agents and is necessary for the normal immune system development. Microbiome can also respond to any changes in a host body and becomes altered («dysbiotic») during diseases or pathological conditions. The exchange between the host and the microbiome occurs constantly, it is bidirectional and integral both during a healthy state and during disease. Therefore, there is considerable interest in microbiome‑based therapy (BM) for a wide range of human diseases. The microbiome is a multi‑level ecological system, and any approach that alters any component of that system can be considered as MBT, or in other words, microbiota therapy. Recently, significant progress has been made in the development of live biologics that help to restore normal gut microbiota and treat various diseases, including Clostridium difficile infection (CDI). Currently, the most common types of MBT are: 1) fecal microbiota transplantation (FMT); 2) a certain consortium of known microbes delivered orally or instilled into the gastrointestinal tract; 3) addition of microbial metabolites (for example, short‑chain fatty acids, butyrate). Interest in the intestinal microbiota has especially increased after the establishment of excellent therapeutic efficacy of FMT at CDI, as well as other intestinal diseases and some extraintestinal diseases that are difficult to treat with traditional methods. This promoted the study of the effectiveness and safety of MBT, such as classical and defined (selective) TFM, treatment with faecal spores or non‑toxigenic strains of C. difficile, classical or new commensal probiotics, bacteriophages or recombinant live biotherapeutic products. This completely new line of treatment, despite its short history, has ushered in a new era in the improvement of treatment aimed at intestinal and metabolic disorders.

Objective — to assess the impact of modern antibacterial therapy on the development of a specific destructive process in experimental tuberculous spondylitis in animals.
Materials and methods. The experiments were conducted on 40 sexually mature guinea pigs (age over 6 months) with an average weight of 350—500 grams. Tuberculous spondylitis was induced using a proprietary method (Patent No. 112423 (UA) Ukraine).All experimental animals were divided into 4 equal groups. Groups 1—3 (main groups) received an injection of 0.5 ml of M. tuberculosis suspension (0.1 mg of dry weight in 1 ml) into the body of the vertebra, according to the specified method. Group 4 served as the control, receiving an injection of sterile physiological solution (0.9 % NaCl, 0.5 ml) into the vertebra.Specific first-line antibacterial drugs (ABDs) consisting of isoniazid, streptomycin, and rifampicin were administered to Group 1, which consisted of 10 guinea pigs. Group 2, also comprising 10 guinea pigs, received specific second-line ABDs, including amikacin, rifabutin and ofloxacin. Groups 3 and 4, each consisting of 10 guinea pigs, received no treatment.
Results and discussion. The morphological analysis revealed the presence of an active tuberculosis process in the vertebral bodies and paravertebral tissues of animals subjected to tuberculosis simulation, regardless of whether they received specific first-line ABD treatment or not. Notably, the severity of destructive changes in affected vertebrae was similar between untreated animals and those treated with first-line ABDs.Animals modeled for tuberculosis and treated with specific second-line ABDs exhibited a suppression of the pathological process. This was evidenced by the formation of immature bone and connective tissue to varying degrees, along with the presence of a delineating zone separating the inflammatory focus from healthy tissue in the early stages of the disease (one month).Conclusions. Based on the histological examination of the vertebral bodies, it was established that the animals treated with specific first-line ABD showed clear morphological features of tuberculous inflammation. In animals treated with specific second-line ABD, inhibition of the pathological process.This study showed that the implementation of modern intensive specific antibacterial therapy in experimental conditions allows to achieve the delimitation of the destructive process in the relatively early stages of the disease development (4—5 weeks).The obtained new knowledge about the pathomorphological features of the course of TS against the background of carrying out specific antibacterial therapy allows radical surgical interventions on the musculoskeletal system without the risk of generalization of the tuberculosis process at an earlier time (compared with the generally accepted ones).

Authors: Al-Rawi Riyadh S. , Kammouna Zainab M. I.
Published: March 2024

the present investigation is concerned with thesevaluation of creep behavior of concrete under variable temperature and relative humidity. It includes analytical and experimental parts. In the analytical part, BP-KX creep model is presented. As this model  considers temperature and relative humidity to be constant, it was modified through considering them to be variable with time, which is the usual case. Functions for the daily variation of these two parameters, according to Baghdad climate, were developed and substituted in the model. In the experimental part, three series of cylindrical specimens (100mm x 200mm) were prepared for the creep test. In series (1), the temperature was raised and simultaneously the relative humidity was lowered just after loading. Series (2). specimens were loaded at high temperature and low relative humidity followed by low temperature and high relative humidity. Series (3) specimens were loaded at low temperature ard high relative humidity followed by high temperature and low relative humidity.Comparison between the analytical and the experimental work confirmed the need for a correction factor to be included in the proposed modified model. The results revealed that concrete specimens subjected to high temperature and low relative humidity, after the load application, will show higher creep than specimens kept at high temperature and low relative humidity before and after lord application. This indicates that specimens loaded in summer show lower creep than those loaded in winter

This research study one of the specialized buildings related to culture, and the cultural activity considered as the basic cause of its architecture presencing. The main role of these centers is to spread culture and to provide ways of natural cultural communication among various societies. These societies differ in expressing culture and methods of cultural activity performance, as the cultural act, with its different levels, connects with each society s civilizational codes and direct this act to meet the spiritual and material needs of the society in general and the person in particular. The difference between cultures had been reflected in the way of performing the cultural activity and the buildings needed for serving this activity and at the same time reflects the cultural specivily of these societies. Therefore, the research problem emerged as the absence of a complete intellectual image of the concept of culture and the way of its reflection as an activity employed within architecture that cultural center expresses it, and it, and also the role of the civilized intellect n changing and differentiating those buildings in shape and function. The research aims to clear this role and its effect in changing the mechanism of cultural act and the changes in the architecture of cultural centers that comes as a result of this change An analytical approach had been adopted in studying the most important buildings that include the general activities of cultural character in different civilizations and number of examples of the modern cultural centers from international, Arabic, and local examples that reflects different types of cultures.
STABILITY ANALYSIS OF SLOPES USING A DOUBLE SLIDING MODEL
Authors: Fattah Mohammed Yousif
Published: March 2024

Experience with Bishop's method, using the shear strength parameters c and obtained fron triaxial compression tests seems to indicate that the values of the safety factor obtained in this way are relatively large. This is sometimes compensated by using shear strength parameters obtained from direct shear tests, simple shear tests, or classical cell tests, which usually lead to smaller values of c and . A solution for the difficulty mentioned above may be the notion that the simple Coulomb formula does not take into account that failure may occur on a plane perpendicular to the global slip surface, with an additional rotation to result in global slip parallel to the slip surface, i.e. double sliding failure model.The essential step in developing the basic formula for many slope stability methods (Fellenius, Bishop, Janbu) is to derive an expression for the normal stress on the slip surface. In the Bishop method this is done by combining the equation of vertical equilibrium in which it is assumed that there is no net contribution of the shear forces on the sides of the slice, with the Coulomb equation.The alternative mechanism proposed is that failure occurs not hecause the shear stress on the slip surface reaches the maximum value described by the Coulomb criterion, but that the shear stress on a plane perpendicular to the slip surface (and thus also the shear stress on a plane parallel to the sl.p surface) reaches the maximum vales on this perpendicular plane, and thus, using a safety factor F In this paper, a comparison is made of the factor of safety calculated by the double sliding model with those calculated by Fellenius and Bishop's methods.

Authors: Al-Suhaili Rafa H. , Nasir Mohsin Jasim
Published: March 2024

The aim of this research was to apply a numerical model capable of describing the thermal pollution in rivers. For this purpose a two-dimensional numerical model was applied for estimating temperature distribution in a river Momentum Conservation Equation and Thermal Energy Equation were used to describe the fdistribution and diffusion of temperature along the river subjected to thermal pollution point source. Furthermore the model incorporates the (k-e) turbulence model to calculate the distribution of turbulent viscosity The pressure distribution was determined using hydrostatic pressure equation. The partial differential equations were formalized and simplified to be solved using Alternative direction implicit- explicit method (ADI) with upwinding technique. The resulting system of linear simultaneous equations were then solved using Gauss-Elimination method. A laboratory physical model was built to find experimental data. These data were used for model verification with data obtained from Al-Daura power station and Tigris river. The model was found to be sensitive to the variation of river velocity and density difference and the model was found to be insensitive to the wind speed. The comparison of observed results from Al- Daura power station and laboratory physical model with those computed by the numerical model show a good agreement. The maximum absolute difference percentage are (16.2%, 8.6%)  respectively

Considerable concentrations of vehicular emissions at signalized intersections and streets, in urban area are health-related issues of concern to society in general. This paper presents an examination for the effect of vehicle driver behaviour on vehicular excess CO emissions. The examination process based on site observations. in Erbil City which, satisfy the objectives and specifications of this Four signalized intersections study selected, and the necessary traffic behaviour and vehicle exhaust emission data collected. The traffic data were collected using video recording technique and the Analytical Mobile Gaseous Emissions CART P8334 machine used to measure vehicle exhaust emission data. The required traffic data abstracted from video play back using EVENT computer program, which provide coded digital representation for the requisite traffic activities. The abstracted data stored on floppy disks in the form of digital computer files. These files processed using computer programs developed for this purpose to abstract the necessary information from the raw data. Among the obtained traffic information are vehicle data classified according to the type of fuel used into two classes. The first class is gasoline powered vehicles which consisted of taxis and private cars covering different model year, engine condition and size, type of fuel injection system, number of cylinders. These data observed under different ambient air temperatures. The second class is the diesel-powered vehicles, which consists mainly of truck type vehicles. Following the processing stage, the obtained data presented and analyzed statistically to evaluate of the relationship between driver behaviour and vehicle excess of CO emission. Among the driver behaviours studied is queuing driver behaviour, which showed reasonably good relationship with the excess CO emissions. The results of this study are useful for the Local Authorities, traffic engineers and transportation planners. This is because, the obtained results assist in the adoption of suitable method of intersection control for the purpose of reduction of CO emissions and hence, reduce level of this type of air pollution.

The possibility of using inhibited hydrochloric acid in descaling of water deposits on heat exchanger and cooling system tubes have been investigated. A dynamic flow system was designed for this state. Experiments were carried out using different, temperatures, solution flow rates,times, and different hydrochloric acid concentrations inhibited with Hexamine. Kinetics of acid iron oxide scale reaction was studied using hydrochloric acid The kinetics analysis showed that the acid- FeO scale reaction followes 1st order reaction. It was found that the FeO scale removal was mass transfer controlling process. Iron- oxide scale removal process was analyzed as mass transfer operation and adequate semi- empirical correlations for scale removal (or mass transfer rate) under different conditions, in a dimensionless form have been obtained. The results of iron- oxide scale removal (or mass transfer rate) are compared with many proposed models particularly those based on the concept of analogy among momentum and mass transfer. Prandtl- Taylor analogy showed a good agreement with experimental mass transfer results.
A FULLY AUTOMATIC GENETIC APPROACH FOR GRAYSCALE IMAGE COLORIZATION
Authors: Attea Bara'a Ali , Al-Janaby Sana'a Khudayer Jaddwa
Published: March 2024

Colorization is a computer assisted process of adding color to a monochrome (grayscale) image ormovie. The early published methods to perform the image colorizing rely on heuristic techniquesfor choosing RGB colors from a global palette and applying them to regions of the target grayscaledimage. The main improvement of the proposed technique is the adoption in a fully automaticway the genetic algorithm as an efficient search method to find best match for each pixel in thetarget image. The proposed genetic algorithm evolves a population of randomly selected individuals (that represents a possible color setting for target image using a reference colored source image toward solution that could resemble natural or real colors to the objects of the target scene). Moreover this study proposes new crossover operator, called Spread out Uniform Crossover (SUX) that turns the recombination scheme of uniform crossover over spreading vital genes at the expense of lethal genes rather than exchanging genes between mating parents to the generated offspring. The results of the proposed colorization techniques are good and plausible.

ANALYSIS OF GALVANIC CORROSION UNDER MASS TRANSFER CONTROLLED CONDITIONS
Authors: Slaiman Qasim. J.M , Hasan Basim O. , Al-Zaidy Baker M.
Published: March 2024

Because of practical importance of protecting industrial equipments from galvanic corrosion, the need arises to analyze the effects of variables, such as temperature, velocity, and area fraction of  metals on galvanic corrosion in systems under mass transfer control as in seawater (pH=7). For these reasons the galvanic corrosion of Fe-Zn is analyzed to study the influence of Reynolds number, temperature, and area fraction on the galvanic corrosion rates and galvanic corrosion potential under mass transfer control. It is found that galvanic corrosion rate of more active metal (Zn) is increased with Reynolds number while the corrosion rate of more noble metal (Fe) is slightly increased with Re depending on the galvanic potential that depends on the area fraction. Increasing Reynolds number shifts the galvanic potential to more positive values. Also increasing temperature leads to shift the corrosion potential to more negative values and to change the corrosion rate of more active metal (Zn) depending on two parameters oxygen solubility and oxygen diffusivity. As area fraction of more active metal (Zn) increased the galvanic potential is shifted to the negative anodic direction while the corrosion rate for more noble metal is decreased.

Active control strategy had been used for controlling the vibration response, with considering thesimplification in the design and keep away from complexity and high cost in order to extend the actualapplication of the active control systems. The control program is responsible for identifying the acquireddata and make comparisons and decisions required for increase or decrease the actuator stiffness, byinstructing the control signal to open the inlet or the exhaust valve respectively. The PC sound card hasbeen used as a Data Acquisition Card. The proposed control strategy had been simulated and tested tocontrol the vibration response of a single degree of freedom spring-mass-damper system excitedharmonically at a fixed frequency and with variations of different system parameters (mass, dampingconstant, and excitation force). Two testing cases are used to investigate the ability of using the proposedactuator and the control strategy in the vibration control field.

This research studying the electromagnetic behavior of the induction furnace when its core is a magnetic material taking into consideration the effect of the non-linear dependence of the magnetic flux induced in it due to the applied magnetizing force. Since the magnetic characteristics are severely affected by temperature rise in a non-linear way, so as the specific electric resistance of the charge material, this work deals with studying the effect of temperature on the non-linear characteristics of a magnetic core simultaneously with that on the specific electric resistance to show the electromagnetic behavior of the furnace during heating operation. The distribution of the current density, flux density and the magnetizing force at different temperatures inside the furnace and on the charge surfaces are determined for different temperatures. Also the flux distribution is plotted at these cases. This study will be the base for future work on the electromagnetic-thermal coupled analysis for the induction furnace.
Stability Issues of Welded Pipe Containing Pulsatile Flows
Authors: Al-Sahib Nabeel K. Abid
Published: March 2024

This paper deals with the dynamics and stability behavior of a welded pipe containing flowingfluid having a small harmonic component superposed. The equation of motion was derived torepresent the motion of a welded pipe conveying a pulsatile flow using a tensioned Euler- Bernoullibeam theory. The finite element analysis was used to simulate the harmonic motion of a welded pipeconveying fluid. It was shown that welded pipes with clamped-clamped and clamped-pinned supportsare subject to a multitude of parametric instabilities in all their modes. Stability maps are presented forparametric instabilities of welded pipe with clamped-clamped and clamped-pinned ends. It is foundthat the extent of the instability regions increases with flow velocity for clamped-clamped andclamped-pinned welded pipes. The most important consideration from a practical point of view is toavoid the onset of parametric resonance.

A program of laboratory testing is carried out to study the performance of laterally loaded piles embedded in soil, which contains cavities. The testing apparatus is manufactured for carrying out the tests and a simple technique was used to simulate the cavities.The program of testing consists of five groups: Group One was carried out on pile embedded in soil without cavities. The Second and Third Groups are performed on pile embedded in soil contain single cavity located in front and in touch with pile face for the Second Group and in back and in touch with pile face for the Third one. Group Four is performed on pile with the existence of two cavities located in front and in touch with pile face. Group Five is performed on pile with the existence of three cavities located in front and at a variable distance from pile face. All tests are performed on a free head pile subjected to horizontal load. The results of this study indicate that the number of cavities and their location have a combined effect on the behavior of laterally loaded pile The effect of cavities located in front of the pile is marginal at X/D > 8 where X is the spacing between cavity and pile and D is the diameter of the pile.
FINITE ELEMENT ANALYSIS OF POST-TENSIONED CONCRETE BOX GIRDERS

Published: March 2024

The behavior of prestressed concrete box-girder bridges has been studied under short term loading.The 20-noded isoparametric three-dimensional brick elements have been used to model the concretein the box-girder with its two cantilever flanges. The reinforcing bars are idealized as axialmembers embedded within the brick elements. The behavior of concrete in compression wassimulated by an elastic-plastic work hardening model followed by a perfectly plastic response,which is terminated at the onset of crushing. In tension, a smeared crack model with fixedorthogonal cracks is used with the inclusion of models for the retained post-cracking stress andreduced shear modulus. The prestressing forces in the tendons are transformed into equivalent nodalforces and by Lin's method. The contribution of the prestressing tendon stiffness to the globalstiffness matrix is considered by treating the tendon as axial member embedded within the brickelement. Two types of short-term prestress losses are considered in this study. The bond-slipphenomenon at concrete-tendon is considered by reducing the tendon axial stiffness. Severalexamples of prestressed concrete box girders are analyzed and compared with availableexperimental and theoretical studies in order to demonstrate the validity and efficiency of theproposed method. Good agreements between the results are obtained.
