This study aimed to determine the significant difference between the scores of the respondents before and after being exposed to stepladder technique in terms of articulation, logical organization, message, stage presence, and facial expressions. It sought answers to the questions: What is the pretest score of the respondents before being exposed to stepladder technique in terms of articulation, logical organization, message, stage presence, and facial expressions? What is the posttest score of the respondents after being exposed to stepladder technique in terms of articulation, logical organization, message, stage presence, and facial expressions? Is there a significant difference between the pretest and posttest scores of the respondents before and after being exposed to stepladder technique in terms of articulation, logical organization, message, stage presence, and facial expressions? The respondents underwent the pretest. Then , stepladder technique was applied in the five literary lessons as an intervention. After all the lessons, the posttest was given. Finally, the posttest level of competence is significantly higher than the pretest, thus stepladder technique is effective. There is a significant difference between the respondents’ pretest and posttest scores. It improved their oral communication competence such as articulation, logical organization, message, stage presence, and facial expressions.

The Language Game of Europe: Politics, Identity and the Divided
Authors: Fatic Aleksandar
Published: July 2023

The paper discusses the psychoanalytic interpretative possibilities for understanding Europe's reluctance to accept the UK's decision to leave the union. It develops an interpretation based on Lucan’s concept of 'Name of the Father' to inquire whether the 'European identity' is in fact a neurotic identity, marked by a blocked presence of the primary Lacanian psychoanalytic signifier and the resultant erratic and ineffective policy which can be considered as a group equivalent of the neurotic symptoms that, in psychoanalysis, are treated as primary individual symptoms. This perspective aims to test the limits of the debate over whether psych diagnostics can be applied to political collectives as well as to individuals, and attempts to do so by drawing parallels between the behavior of individual people, on the one hand, and institutions, on the other.
Tomorrow in the Outer Space Remember the Dreaming
Authors: Stroe Ilinca
Published: July 2023

With a pastiche title reminiscent of novelist Javier Marias’s tomorrow in the Battle Think on Me, this article sets out to compare two extremes of “identity, difference and memory”: Western trans-humanism and Australian Aboriginal Dreaming. The main assumption is that the two have drawn on surprisingly similar concepts (immortality/eternity, universality/ubiquity), and yet their approach to the individual and to self-management sets them wide apart. While avoiding to idealize either of them, the article does plead for a “return of knowledge” from the formerly colonial space to the formerly colonizing world.
The Metaphorical Load of Philosophical Consultations in Psychotherapy
Authors: Tiurean Anca-Cornelia
Published: July 2023

The paper propose the idea that philosophical practice has a metaphoric dimension which reveals the human subject’s cognitive biases and psychotherapeutic necessities. To support this claim, the focal point of author MA thesis in Philosophical Counseling and Consultancy was to consider metaphor from various perspectives: ontological, esthetic, epistemological, existential, social constructivist, ethical and practical. Throughout this theoretical task, was explored applications of metaphor in working towards people’s health and wellbeing across the lifespan using an integrated metaphor-based approach in consultations, including philosophical practices and transactional analysis. This article shows various definitions of metaphor, descriptions of how we know through metaphor and what psychotherapy has implied along its history as a practice.
Women's Circles and Philosophical Practice
Authors: Todor Ramona
Published: July 2023

In recent years, traditional approaches to education and development have been increasingly criticized as being predominantly oriented towards developing the mind, at the detriment of the other dimensions of human existence (i.e., body, emotion, intuition, imagination), which have been associated with secondary, less important, or feminine aspects. Such an approach understands and engages these other dimensions merely from a mental perspective, instead of allowing each dimension to develop in its own space and rhythm. This creates a bias referred to as cognicentrism. A case for the shift of cognicentric approaches towards an integrative interplay of the mind, body, emotion, imagination, and intuition is presented in this study. This shift is envisioned as happening by pursuing an embodied, immanent approach towards all dimensions of knowing in an integrative manner. As one of the steps towards this achievement, in the context of philosophical practice, the practice of Circles of Women (CWs) is presented and studied. CWs are presented as spaces where the practice is centred on embodiment and immanence, where the voice of the feminine can be heard, explored, and honoured – aspects perceived as lacking in the context of a traditional philosophical practice. Philosophical practice is presented as having a more accentuated presence on the mental, intellectual sphere, and so a more versed perspective upon matters of ethics and logic – aspects through which CWs could also potentially benefit. The direction and focus of this study is to advance the need for an embodied, immanent approach to philosophical practice, thus building bridges between already existing practices and communities while acknowledging differences and presenting possibilities of complementarity or reciprocal influence.
The teachers' perception of the factors that promote the cultivation of creative thinking
Authors: Zoabi Mahmoud
Published: July 2023

In recent years, the subject of creative thinking has taken a central place in the various areas of life promoting these important areas by proposing innovative ideas and solutions. In a special way, the issue of creative thinking in the field of education has recently been found as a central issue, putting it in the central of many curriculums and calling for its cultivation among students. A major reason for that is that the world that has become dynamic and is changing rapidly in recent years, especially thanks to the rapidly advancing technology that affects all areas of our lives, educational, economic, social, political and others. So much so, in many educational systems, they started talking about preparing the learner for the unknown future. Since creative thinking is thinking that breaks rules and norms, it allows seeing or creating unknown connections between different components, thus enabling the creation of new and unknown ideas and solutions that will help the learner to successfully deal with everyday problems and promote himself successfully in all areas of life. As a result of what was said about the importance of creative thinking and the importance of cultivating it, a comprehensive study was carried out that examined the perception of science and technology teachers in Arab elementary schools in Israel on seven key dimensions in the context of creative thinking. The number of teachers who participated is 313 which cover the variables: age, seniority in teaching, academic degree, and geographical distribution of residences. A central dimension was the teachers' perception of the factors that foster creative thinking. A central reason for examining the teachers' perception is that the teachers and not others are the ones who carry out the teaching, learning and assessment processes in the school, they are the actual mediators between theory and application, so that the cultivation of creative thinking depends to a large extent on their way of activity. In addition, the teachers' perception was examined among science and technology teachers since the field of science and technology is found according to much research literature as a field with a high capacity for cultivating creative thinking. This article presents findings, conclusions and recommendations that arise in terms of the dimension of the teachers' perception of the factors that foster creative thinking. The article presents a picture in which the teachers' perception of the factors that foster creative thinking is in high agreement with what is said about these factors in the research literature, even if there is no research based on the teachers' perception, this is when the summary of this perception is that significant changes are required in most factors of school activity in order to cultivate creative thinking of the students, in methods, tools and environments of teaching, learning and assessment, the willingness of teachers to teach creative thinking and readiness for taking risks on the part of the teachers and students.

Happiness is a current important subject of study in psychology and social science because it affects people's day-to-day lives, thoughts and feelings, work habits, and interactions with society and family. There are a number of challenges in Computer Science and Machine Learning to predict happiness index using prediction techniques. This study presents a systematic review using PRISMA style for happiness prediction. During the Literature survey, it was found that many predictive models whether statistical or Machine Learning was designed to predict happiness index but a major emphasis on research remains focused on the factors that are listed in World Happiness Report, i.e., real Gross Domestic Product per capita, social support, healthy life expectancy, freedom to make life choices, generosity and perceptions of corruption. The factor influencing happiness varies due to personal differences, age group and location variation. According to Gallup Poll, the general annual sample for each country is 1,000 people i.e., approximately 0.007% population participated in happiness index measurement. The purpose of this study is to discover and describe new factors related to psychology like stress and emotions, location-based and age group. It is observed that there is a requirement to develop a Machine Learning predictive model which works on psychological factors like mental health, depression, stress, physical well-being, safety, leisure time available, and suicidal ideation in addition to economic factors used in World Happiness Index and by targeting a large sample size of populations.

Published: July 2023

In this study, we report the green synthesis of copper-doped titanium nanotubes using a biogenic approach. Lemon peel extract was used as the reducing and capping agent for the synthesis of copper-doped titanium nanotubes. The formation of the nanotubes was confirmed by various characterization techniques such as X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy. The results showed that the copper-doped titanium nanotubes had a high degree of crystallinity and a well-defined tubular structure. The photodegradation of methylparaben was used to evaluate the photocatalytic activity of the nanotubes, and it was found that the copper-doped titanium nanotubes exhibited excellent photocatalytic activity under UV light. This study presents a simple, cost-effective, and environmentally friendly method for the synthesis of copper-doped titanium nanotubes, which can be used as an effective photocatalyst for the degradation of organic pollutants.

Published: July 2023

In this study, we add further information about the genetic variation and admixture of Apis mellifera subspecies in Albania. The genetic diversity of the honey bee (Apis mellifera) remains undescribed in some parts of its natural distribution range but yet the distribution of subspecies is nowadays also much influenced by beekeeping activities, so the aim of this study was a genomic evaluation of the current state of Albanian bee population. In total, 10 samples (30 bees) of different subspecies which are claimed to be bred in Albania were analyzed. Morphometric identification of the samples was done through the specialized program Identyfly, which automatically performs a racial classification of bees based on the angles of the front wings of different subspecies. The analysis of the results obtained with the Identyfly program showed a high level of subspecies admixture in the breeding populations. The beekeepers claimed that they bred subspecies of the evolutionary lines M, A and O, except of our autochthonous subspecie (Apis mellifera carnica) which belongs to the evolutionary line C.Our results indicate also that in Albania breeds more than 12 subspecies of Apis mellifera which belong to 4 evolutionary lines. The subspecies that the beekeepers claimed they were breeding did not turn out to be such, but were hybrids between them. This high hybridization may lead to greater genetic diversity of our native bee populations. All these results showed that the increasing introgressive hybridization with managed non-native subspecies, may lead to the loss of valuable combinations of traits shaped by natural selection. We suggest the establishment of a racial improvement center in Albania, and also the future research should focus on genetic analyzes with a greater coverage of bee populations in Albania.

Published: July 2023

Improving energy efficiency in the building’s design is a priority area. To avoid unnecessary energy consumption, electronic control (intelligent) systems can be used to measure and monitor heat exchange between building walls and the surrounding environment, as (Calorimetric Sensor, Heat Flux Sensor ...). They are ideally suited for research in rationalizing and improving thermal efficiency. The aim of this study was a computational fluid dynamics investigation of unsteady turbulent flow and heat transfer of dynamic heat flux sensor for quantitative description of the heat transfer between the building's walls and the surrounding environment.Using CFD software, we numerically simulated the wind tunnel where the sensor was installed; we used six different air speeds (Vinlet=2m/s to 12m/s) in the inlet. To improve the standard features of the CFD code, the User-Defined Function (UDF) was written in the C language program and integrated into the solver of ANSYS Fluent, in order to determine the thermal flow file applied to the surface of the sensor. Heat transfer coefficient (h0) values are obtained according to each speed. The results obtained were compared to results in previous experimental and theoretical literature. There is a good compatibility of all results that allows dependence on numerical simulations in the future as a way of stewardship when studying energy rationalization.
Modeling and Simulation of a cooking inductors by Electromagnetic Induction
Authors: Aroua Fatima Zohra , Salhi Ahmed , Mohamed Rezig , Naimi Djemai
Published: July 2023

The fundamental concepts of induction heating have been discovered and applied to industrial processes since the 1920s. Its principle is based on the direct application of two physical laws, Lenz's law, and the Joule effect. The development of electromagnetic induction principles in cooking systems is progressing, as they offer better working conditions, good safety, high energy efficiency, and low pollution. Induction heating is the transmission of electromagnetic energy through the surface of a heated material via three physical phenomena: permeability, electrical conductivity and thermal conductivity, depending on temperature. This electro-thermal technique permits electrical conductive materials to be heated without physical contact with an electrical source. In particular, the study of the inductor position in the heating plate can improve and normalize the induction heating temperature. In this work, we proposed several geometries for cooking inductor position based on numerical modeling of induction heating processes using the finite element method on Matlab to solve all electromagnetic problems. The chosen geometrical model with 3 inductors has a good temperature distribution in the heating plate of about 650 K (377 C).

Published: July 2023

Peanuts, lentils, sesame and cowpeas are protein-rich legumes widely consumed in the human diet. However, some so-called allergenic proteins are capable of causing adverse reactions in genetically predisposed individuals. They contain portions consisting of contiguous linear segments of amino acids involved in binding with specific IgE. They also have three-dimensional conformational patterns that crosslink with antibodies from susceptible individuals. In this work, the identity and similarity between certain allergenic proteins of peanut, lentil, sesame and cowpea are studied by global alignment. The latter is carried out on 21 allergenic proteins (7 from peanuts, 3 from lentils, 3 from sesame and 8 from cowpea) using the EMBOSS Needle software which uses the Needleman-Wunsch algorithm and assigns scores to the pairs of amino acids aligned using a specific BLOSUM substitution matrix. For statistical analysis, the dependency test and the chi-square test are used in GraphPad Prism and R-studio.The results show that the overall alignment between allergenic proteins from the same food (Peanut - Peanut, Sesame - Sesame, and Lentil - Lentil) and different foods (Peanut - Lentil, Peanut - Sesame, Lentil - Sesame, Lentil - Cowpea, and Sesame - Cowpea) has low identity and similarity.The overall alignment between the allergenic proteins of the same food (Cowpea - Cowpea) and of different foods (Peanut - Cowpea) shows a strong identity and similarity, relative to the result of the chisquare test. The possibility of cross-reactivity between cowpea and peanut is shown.

Published: July 2023

– Mortar is a mixture of sand, cement, water and eventually additives. With the environmentalissues, mortars are increasingly formulated with mineral additions as a substitute for cement in order toproduce ecological mortars. It is one of the most widely used cementitious materials in the field ofconstruction and civil engineering after concrete. Mortar placement techniques are evolving day by day,such as pumping, spraying and injection. Therefore, knowing the rheological behavior of mortars becomesmore and more crucial to master their implementation techniques. This study presents the development ofa vane rheometer to estimate the plastic viscosity yield stress of mortars. The rheological parameters weredeveloped from measurements using a procedure to convert data from moment torque and rotational speedto shear stresses versus shear rate. The procedure used considered the locally sheared material as a Binghamfluid and calculated the characteristic shear rate from the quilt analogy. The device was tested with threeexperimental programs in which many rheological parameters of the compositions of different mortars werecalculated. The results obtained validated the developed rheometer test procedure and confirmed that thetest results are reproducible and repeatable. Measurements were made on different compositions of mortarof each mineral addition, altering the amount of blast furnace slag (BFS) and fly ash (FA) in order toevaluate the impact of supplemental cementitious materials and industrial wastes on the rheologicalcharacteristics (plastic viscosity and yield stress) of eco-friendly mortar..
Numerical Study: Comparison of Paraffin Deposition In The Laminar And Turbulent Regime
Authors: Benhacene Oussama , Boucetta Rachid
Published: July 2023

The problem of paraffin deposits in oil wells and pipelines monopolizes substantial human and economic resources. Its prediction is, therefore, essential to optimize its management. The formation of the deposit arises from a delicate interplay of hydrodynamic, thermal, and thermodynamic factors, alongside paraffin diffusion and the rheology of the crude oil. This research has resulted in a better understanding and calculation of the rates at which wax is removed. Furthermore, the study has suggested the presence of two distinct flowing regions in turbulent and laminar flow, which results in the formation of thin solid sediments attached to the pipe wall.By conducting this numerical study using FORTRAN, we can gain insights and optimize the design and operation of pipelines and maintain efficient production. The study also involved a rough comparison between the results obtained from two different types of flow. This approach, which considers the viscoelastic behavior of paraffinic crude, allows for a more accurate prediction of deposit formation. With this enhanced understanding, we can develop improved strategies for managing paraffin build-up, minimizing resource allocation and costs associated with its removal. Ultimately, optimizing the design and operation of pipelines will contribute to the maintenance of efficient production in the oil industry.

Virtual screening of natural meroterpenoids towards SARS-CoV-2 main protease
Authors: Arslan Idris
Published: July 2023

The term meroterpenoid states hybrid secondary metabolites which are partially derived from terpenoids and synthesized in terrestrial plants, marine animals, and fungi. So far, myriads of meroterpenoids with unique chemical structures and promising bioactivities were documented. Virtual screening is a widely used, relatively fast, and economical simulation tool for predicting in silico the binding modes and affinities of molecular recognition processes. In the present study, we tested on SARS-CoV-2 main protease inhibitory activity of some selected meroterpenoids [(stachybotrylactone (1), stachybotrylactone acetate (2), and 2α-stachybotrylactone (3)] by distinct algorithms which has been one of the most basic and important strategies for drug design. Our findings showed that stachybotrylactone acetate (2) had a significant free binding of energy towards the viral main protease at the value of -6.34kcal/mol.

In this work, interaction energy values were calculated using ab initio method for Trimethylgallium (TMGa) molecule. For the Trimethylgallium molecules, the minimum energy values obtained by the ab initio method have been used to calculate second virial coefficient by placing in Yukawa potential. The obtained second virial coefficient results are compared to theoretical data reported in the literature. Furthermore, the obtained results for Yukawa potential compared to with other potentials such as Lennard Jones (12-6) potential and Morse potential in the literature. For most of the varied temperatures of the investigated TMGa molecule, the second virial coefficient predicted by theoretical result computations showed reasonable agreement with theoretical second virial coefficient values.

Structural and dynamic analyzes of the wind turbine, which is thought to be built in the Mamurdağ location of Samsun İlkadım District, has been tried to be analyzed using the Finite Element Method.The main purpose of this study is to numerically examine the dynamic behavior of the wind turbine under the existing ground conditions of Mamurdağı for the Wind Turbine. The turbine preferred as a model in this study is the 73m high 800Kw wind turbine belonging to Enocon Company. Modeling was made in the light of the technical data of the relevant company. While the numerical model was being created, the blades of the wind turbine and the nacelle-rotor system were not modeled, but the actual weight, corresponding to approximately 81 tons was applied as a load to the system. In the last part of the article, the dynamic properties of this 73m high tower are examined to obtain the natural frequencies and mode shapes. As a result of the analysis, 5 different mode shapes, frequency and period values of the wind turbine planned to be built were obtained. According to the modal analysis results of the wind turbine, the result of the dominant frequency was obtained as 0.72327 (cycles/time). First Mode is in the y-x plane so this is the lateral movement in this direction.

Bilişim sistemlerinin her alanda kullanılması nedeniyle siber güvenlik tehditleri artmaktadır. Bilindiği üzere günümüzde bilgiye erişim ihtiyacı her an doğabilmektedir. Artan kişisel erişim ve İnternet kullanımı milyarlarca cihaza yayılmakta, zettabayt boyutunda verileri ortaya çıkarmakta ve siber güvenlik tehditleri oluşturmaktadır. Siber güvenlik tehditleri, kişi ve kurumların bilgi ve iletişim sistemlerindeki bilgi güvenliği açıklarını her geçen gün artırmaktadır. Bu durum sistem çalışmazlığına, finansal kayıplara ve siber güvenlik riskine neden olmaktadır. Yeni teknolojilerin siber savunma sistemlerine adapte edilmesi, tehditlerdeki yeni teknolojik artış göz önüne alındığında çok kritik olduğu görülmektedir. Bu kapsamda yapay zekâ uygulamaları, siber güvenlik alanında kullanıcı davranışlarını analiz ederek iyi ve kötü aktiviteleri ayırmak için kullanılabilmekte, birbirinden bağımsız gibi görünen saldırı göstergelerini yorumlayıp korelasyon kurallarına göre alarm üretebilmektedir. Ancak yapay zekâ sistemleri açıklanabilirlik konusunda yetersiz kalabilir ve sınırları olabilir. Açıklanabilir yapay zekâ (AYZ) burada devreye giriyor. AYZ sonuçların geliştirilmesine, anlaşılmasına ve yorumlanmasına yardımcı olur. Bu araştırma kapsamında kurumsal ağlara yapılan saldırılarda, saldırıların tespitinde başarı oranının artırılması, yeni saldırı tiplerinin tespit edilmesi ve saldırı tiplerinin açıklanması amacıyla açıklanabilir yapay zekâ sistemi oluşturma amaçlanmıştır.
Impact of Al2O3-Cu/Water Hybrid Nanofluid and Impinging Jet on Moving Plate at High Reynolds Numbers: A Numerical Study
Authors: Ekiciler Recep
Published: July 2023

Numerical research utilizing the commercial code ANSYS FLUENT is conducted to examine the heat transfer from a heated moving surface caused by confined slot-jet impingement at high Reynolds numbers. Confined slot-jet impingement's flow and thermal fields are studied using the SST k-wturbulence model. Important parameters such as high Reynolds numbers (50000, 100000, and 150000), different working fluids (water and 1.0% Al2O3-Cu/water hybrid nanofluid), and different impinging surface velocities (Vp=0, 2, and 3 m/s) are investigated on Nusselt numbers, skin friction factors, temperature contours, and velocity streamlines. According to the results, it is determined that the Nusselt number increased as the impinging surface’s velocity increased. While the Nusselt number grows with the increament in the Reynolds number, the skin friction factor tends to decrease. The utilization of 1.0% Al2O3-Cu/water hybrid nanofluid as the working fluid also has a substantial influence on heat transfer.
PHYSICAL EXAMPLES OF NONLINEAR DYNAMICAL SYSTEMS

In this study, some important physical systems, which are examples of dynamic systems that exhibit chaotic behavior, are given. These are field models with spinor fields, which are especially important in particle physics. In this study, Duffing, Thirring and Dirac-Gursey systems will be discussed. The Duffing equation is a famous nonlinear differential equation that exemplifies a dynamical system that exhibits chaotic behavior. Various forms of the Duffing equation are used to describe many nonlinear systems. The Duffing equation serves as a test model for us to understand the dynamics of the nonlinear spinor field models we are working on. Thirring system is a relativistic field theory for the interaction of fermions. It is two-dimensional massless system. Since the Thirring system is the simplest nonlinear spinor system, it has an important place in particle physics as a toy model. The Dirac-Gursey system was proposed in 1956 to realize the dream of Heisenberg and his friends. It is the first nonlinear spinor wave equation with four dimensions and conformal invariance. Due to these properties, it has a wider symmetry than the Dirac equation and the equations proposed by Heisenberg et al. Gursey became the first physicist to test conformal invariance in spinor field theories with this system he proposed in 1956.

Wired communication refers to data transmission over a wire-based communication technology. Also, in computer engineering terms, a network is defined as a group of computers connected to share information or services (print services, multitasking, etc.). In this paper, the performance of a wired network that consists of more than 300 nodes which implement as an example of a big organization (i.e., Sakarya University), is investigated and analyzed by simulations using a network simulator tool (Ns2). The analysis depends on many performance metrics such as throughput, delay, Jitter, etc. Results show that modeled network has enough performance in different scenarios.

Dünya’da enerjiye talebin artması, sınırlı fosil kaynaklar ve çevre kirliliği gibi faktörlerden dolayı temiz ve verimli enerjinin önemini artırmış ve dikkatleri atık ısıların değerlendirilmesine çevirmiştir. Gaz türbininden çıkan sıcak egzoz gazlarının ısı enerjisi atmosfere atılmadan önce ısıtmada kullanılmak üzere sıcak su ya da buhar üretiminde (kojenerasyon), hem ısıtmada hem de soğutmada (absorpsiyonlu) kullanılması (trijenerasyon), güç üretiminde ya da başka amaçlarla kullanılması da mümkündür. Gaz türbinli güç çevrimlerinin atık egzoz gazı ısısından tekrar güç elde etmek için sisteme buharlı ya da organik Rankine çevrimi eklemek son yapılan araştırmalarda en iyi çözümlerden biri olarak ortaya çıkmıştır. Gaz türbinli güç tesisine buharlı Rankine çevrimi eklenerek elde edilen sisteme Termodinamiğin birinci ve ikinci kanunu ile ekserji analizi metotları uygulanarak analiz edilmiştir. Bunun için Fortran dilinde bir program yazılarak çalıştırılmış ve elde edilen sonuçlar Literatürdeki çalışmalarla karşılaştırılmıştır. Gaz türbinli güç çevrimi ile gaz türbinli kombine çevrimin değişen kompresör sıkıştırma oranlarına ve değişen hava fazlalık katsayılarına göre ekserji verimi, güç artışı ve diğer performans özellikleri değişimi karşılaştırılarak avantaj ve dezavantajları ortaya konmuştur. Ekonomik analiz ve maliyet analizi yapılmadan yakıttan elde edilen tasarruf, birim kilo Watt için her iki durumdaki harcanan yakıt miktarları ve performanstaki iyileşmeler gösterilmiştir. En iyi performans değerlerini elde etmek için çalışılması gereken kompresör sıkıştırma oranı ve hava fazlalık katsayısı yani optimum çalışma şartları elde edilerek gösterilmiş ve tartışılmıştır.
