This research endeavors to examine the effect of stiffener shapes on the structural capacity of stiffened-plate structures, specifically focusing on Tee (T), Angle (L), and Flat (I) stiffened plates. The primary objectives are threefold: firstly, to quantify the critical load values during the buckling phenomenon for T, L, and I stiffened plates; secondly, to assess model deformation upon failure; and thirdly, to investigate whether the buckling behavior of T, L, and I stiffened plates correlates with distinct failure patterns. Employing numerical simulation through the finite element method, this study sheds light on previously unexplored aspects of structural behavior. The findings indicate that angle stiffeners exhibit superior load-bearing performance compared to flat bars. Notably, the research reveals a substantial increase in maximum compressive load by at least 15.90% with Tee bar and 8.25% with angle bar stiffeners when the stiffened panels undergo a 5 mm displacement, presenting a potential avenue for structural enhancement. Additionally, the study demonstrates that T bars outperform in terms of resisting buckling. Noteworthy is the novel approach of examining the combined effect of transverse frame, longitudinal frame, and hull girder under buckling scenarios, a facet not explored in previous research. Furthermore, the utilization of steel S355JR-EN10210 as a material introduces a unique dimension not previously considered in these scenarios. Doi: 10.28991/CEJ-2024-010-04-03 Full Text: PDF
Optimizing Alkali-Concentration on Fresh and Durability Properties of Defected Sanitary Ware Porcelain based Geopolymer Concrete
Authors: Wongpattanawut Woratid , Israngkura Na Ayudhya Borvorn
Published: May 2024

Introducing defective sanitaryware porcelain as a low-calcium binder for geopolymer mix concrete was regarded as green concrete. Four alkali concentrations (8M, 10M, 12M, and 14M) mixes involving four initial curing temperatures (60°C, 75°C, 90°C, and 105°C) were investigated for porosity, rapid chloride penetration, compressive and abrasive resistance. Tests on geopolymer paste for consistency and initial and final setting times were also assessed. For all the mixes, consistency and setting time decreased with increased alkali concentration levels. An increment in curing temperature increased the setting time rate. Microstructural studies such as X-ray fluorescence analysis (XRF), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were carried out, and the results were presented. The compressive and abrasive resistance of the specimen performance increased with an increase in the initial curing temperature and alkali concentration level. Majorly, the mechanical strength of porcelain-based geopolymer specimens increased by increasing the alkali concentration level. Applying 105°C for the initial curing temperature to the specimen, compressive strength, abrasive resistance, and resistibility to chloride ingress of the specimen enhanced. At the 28-days curing period, the ultimate compressive strength was 68.03 N/mm2, the lowest weight loss from abrasive motion was 0.09%, and the lowest passing charge was 1,440.91 coulombs were recorded respectively. As a result, porcelain-based geopolymers required a high initial curing temperature and a high alkali concentration level. It was found that 14M porcelain-based specimens heated at 105°C curing temperature for 24 hours led to an eco-friendly concrete mix with prominent positive results for engineering properties. Doi: 10.28991/CEJ-2024-010-04-05 Full Text: PDF

Published: May 2024

This study aims to determine the needed coefficients for evaluating the uniaxial compressive strength characteristic value for masonry structures made of Laterite Stone (LS) and cement mortar, resulting from experiments conducted in the laboratory evaluating the compressive strengths of the laterite stone and mortar separately in masonry. It proposes calculation coefficients for the completion of Eurocode 6 data that fit the behavior of laterite stone-based masonry. The laterite stone blocks are extracted from three quarries in southern Burkina Faso. The dimensions of the masonry samples tested are 800 mm × 800 mm × 135 mm (±5 mm) with a cement mortar joint of 20 mm (±5 mm) thick. The different failure modes of masonry were also explored. The tests carried out on the masonry showed that the failure is initiated by vertical cracks through the block-mortar interface at a quarter of the width of the walls, generally at 40 to 60% of their maximum strength. The statistical analysis made through a linear regression from the standard model of approximation of the characteristic strength of masonry in Eurocode 6 was used to set out parameters for the empirical relation. The proposed formula considers the intrinsic properties of the block and the mortar, the thickness of the mortar, the dimensions of the masonry block, and the geometry of the masonry itself to evaluate its compression strength. The adequacy between the model and the experimental values is evaluated through the coefficient of determination and the standard error of 0.94 and 0.041 MPa, respectively. Doi: 10.28991/CEJ-2024-010-04-07 Full Text: PDF

Published: May 2024

Sustainable construction is a rapidly growing area of research focused on using industrial waste to replace Portland cement in concrete. This approach not only reduces CO2emissions from cement production but also serves as an effective way to diminish the environmental impact of concrete production. This study aims to investigate the properties of Coal Bottom Ash (CBA) after undergoing two different treatments: flotation and burning. It also evaluates the impact of CBA as a cement replacement in concrete with different replacement percentages (5%, 10%, 15%, and 20%). Chemical analysis of CBA has revealed that it can be classified as a pozzolanic material due to its high content of silicates, aluminates, and iron oxides. The microstructure of CBA showed a porous, angular, and irregular surface with many voids. The findings of this study revealed that the optimum mix was 10% CBA, resulting in a 2% increase in compressive strength compared to the control mix after 56 days of curing. Additionally, the study evaluated the effects of sulfate and chloride on concrete. It was found that the mix with the burning treatment showed an overall increase in strength, while the flotation treatment did not reach the control mix's strength in any of the curing periods. Furthermore, the results demonstrated that CBA has significant potential as a cement replacement material, and the burning treatment showed improvement in concrete's overall properties compared to the raw material in terms of mechanical and chemical properties while reducing greenhouse gas emissions and enhancing the environment. Doi: 10.28991/CEJ-2024-010-04-08 Full Text: PDF

Published: May 2024

As specified by regulatory bodies, the current study intends to investigate the dissolving characteristics of a generic medicine product and its matching standard reference medication under Biowaiver settings. Through this comprehensive analysis, we validate the suitability of the generic drug for Biowaiver considerations. Consequently, it may potentially serve as a cost-effective alternative with therapeutic equivalence to the standard reference drug. These findings emphasize the significance of dissolution profiling in supporting the assessment of pharmaceutical quality and regulatory decision-making. This review paper also provides an overview of methodologies and statistical techniques used to compare dissolution profiles, which is a critical aspect of pharmaceutical quality assessment. The study investigates various approaches, including model-independent and model-dependent methods, in line with regulatory guidelines for evaluating whether the dissolution profiles are equivalent or comparable. We discuss the significance of choosing suitable metrics and acceptability criteria, and the effects of process and formulation modifications on dissolving profiles. The study's findings show that dissolving profiles are similar, suggesting that the generic drug's formulation satisfies the requirements to be eligible for Biowaiver. Therefore, it possesses potential for substitution with the standard drug under appropriate circumstances.

Published: May 2024

Currently induction motors are widely used in industry because of their strong construction,high efficiency, and low maintenance. Machine maintenance is necessary to extend the life of the induction motor. Based on previous research, bearing faults can cause 42% - 50% of all motor failures. Generally this is caused by manufacturing errors, lack of lubrication and installation errors. Motor misalignment is one of the errors in installation. This research is concerned with descrete wavelete transform simulations to identify misalignment in induction motors. Modeling of motor operation is introduced in this paper as normal operation and two variations of misalignment. Haar and symlet wavelet transformations at the first level to the third level are used to extract the motor vibration signal into a high frequency signal. Then the energy signal and other signal extracts obtained form the high frequency signal are evaluated to analyze the condition of the motor. This evaluation process uses fuzzy logic of the fuzzy subspace cluster type. The results of research using a combination method of signal processing in the form of DWT and artificial intelligence methods of the fuzzy subspace cluster type. Then the occurrence of misalignment in three-phase induction motors can be detected early. So that maintenance and replacement can be anticipated before misalignment occurs. From the experimental result, it was obtained that motor and clutch endurance test for level 1 of the fuzzy subspace cluster method was 0,88% better than the fuzzy c-mean method of 0,75%.

The rapid development of information technology is accompanied by an increase in cyber incidents such as data breaches. One of the security methods that can be implemented to enhance data security against data breaches is by applying cryptography to data management systems. Cryptography is useful for encrypting plaintext into ciphertext, making the data not easily readable. One of the encryption algorithms widely used in data security is Blowfish and Twofish. Blowfish and Twofish are symmetric encryption algorithms that use a single key for encryption and decryption. This journal focuses on testing the encryption and decryption of Blowfish and Twofish algorithms in relation to space and time complexity. The results of testing three sets of data on two different devices indicate that the Blowfish algorithm has better speed than Twofish, while Twofish performs better than Blowfish in terms of memory usage. Moreover, the usage of the processor affects the speed of the process.

Rapid economic development and urbanization in Indonesia have resulted in an increase in the amount of transportation. The increasing number of transportation users is not balanced with the increase in driving awareness, thereby exacerbating transportation problems. This imbalance has caused driving safety in Indonesia to become a concern. This is proven by the increasing number of traffic accidents and causing many victims. As many as 73% of traffic accidents occur when the weather is sunny and hot. Road temperature affects the friction that occurs on vehicle tires. The friction that occurs between the tires and the asphalt road causes changes in the structure and thickness of the vehicle tires which can trigger tire rupture on the vehicle. Based on these problems, the innovation of a tire pressure and temperature detection device using an infrared pyrometer sensor has emerged with additional modifications that enable the tire pressure detection device to work optimally and provide convenience for its users.

The aquarium will be made as comfortable as possible for the fish to live in so that they do not easily experience stress and die. The problems often experienced by aquarium owners, many owners still do not pay attention to the conditions in the aquarium environment, namely water pH, temperature, turbidity, salt levels. So this aquarium was created using a water PH sensor, temperature sensor, turbidity sensor and salinity sensor to take water quality readings and then process them in ESP32 using the results of these sensor readings which will be displayed on the LCD screen and recorded in Google SPedsheed. ESP32 will give orders to the pump to dissolve the solution that has been set to neutralize the water pH of 6.5-7.5 if the water is in alkaline/acidic conditions. When the temperature sensor reaches 25°C the heater will turn on, but when the temperature is above 30°C there is no action. The pump will also turn on to regulate water turbidity and normal water salt levels, and will turn off if the water is in good turbidity conditions, namely below 10 NTU and good salt levels, namely 4 ppt. This system can monitor and control water quality in real time and is able to provide notifications when water quality exceeds a predetermined standard value. By making this tool, the water quality parameters are recorded well, so that the fish grow well and do not experience stress or death.

Research and reporting on university rankings serve as valuable tools for students in evaluating universities and understanding their current performance status. Within academic literature, university rankings are established using diverse criteria across various domains, each carrying varying degrees of importance. This study adopts a multi-criteria decision-making (MCDM) perspective to analyze the academic performance ranking of Turkish Universities in 2023. Data sourced from the 2023 reports of sixty-one universities from Times Higher Education (THE) serve as the basis for this research, with THE indicators—teaching, research, citations, industry income, and international outlook—considered as primary research criteria. The Method based on the Removal Effects of Criteria (MEREC) method is employed to ascertain criterion weights, while the Weighted Euclidean Distance-Based Approach (WEDBA) method is utilized for university ranking. The study identifies "citations" as the criterion of highest significance. Notably, the top-performing universities in the ranking include Çankaya University, Fırat University, and Bahçeşehir University. Furthermore, by comparing the rankings from this study with THE university rankings, the research offers tailored suggestions for universities. This study underscores the importance of deriving criterion weights from university performance datasets rather than relying on fixed weights, facilitating a more nuanced approach to university rankings. Moreover, it presents THE performance rankings for sixty-one Turkish universities, offering valuable insights for strategic planning within the university sector.

Perceived Corruption is a Robust Associate of Conspiracy, Paranormal, and Pseudoscience Beliefs
Authors: Alper Sinan , Düzgün Ayşenur , Atalay Eylül Deran , Yilmaz Onurcan
Published: May 2024

Although country-level corruption predicts conspiracy beliefs, the use of country-level indices suffers from limitations, such as ecological fallacy and limited number of countries. We utilized the individual-level perception of corruption to understand whether it is a predictor of conspiracy beliefs and whether this relationship extends to other epistemically suspect beliefs, like paranormal and pseudoscience beliefs. We also controlled for individual-level differences previously shown to be effective such as demographic factors (age, sex, education, SES), socio-political attitudes (ideology, religiosity, right-wing authoritarianism, social dominance orientation), personality traits (Big Five and Dark Triad), cognitive sophistication (cognitive reflection and science literacy), and generalized social trust. In three samples (Ntotal = 5,400; Turkish and British participants), we found that perceived corruption is still a robust associate of conspiracy, paranormal, and pseudoscience beliefs, even after accounting for all these relevant factors. The results are consistent with the argument that perceived corruption plays a fundamental role in the formation of epistemically suspect beliefs beyond other factors.
From Ordinary to ExtraOrdinary: The Role of Placebo Effect on Intuitive Guessing
Authors: Boscariol Riccardo , Tressoldi Patrizio
Published: May 2024

This research examines the placebo effect on intuitive guessing within forced-choice tasks, specifically using the Zener cards test and a sound stimulus as the placebo inducer.Results from 100 naive participants demonstrated that the 'Placebo' condition achieved significantly higher correct response rates than expected by chance, with 22.3% success rate vs. 20.0% (binomial test = 2.85, p-value approximately 0.005, Cohen’s h = 0.056). Control group analyses, which included 50 participants, ruled out the possibility that these results were due to a learning effect from the order of experimental conditions.Analysis using a GLMM for binary data explored the role of experimental conditions and other variables on participant performance. The model included factors such as condition ('No-Placebo', 'Placebo', 'First Control Session', and 'Second Control Session'), participant self-reported confidence scores and reaction times, as well as reaction times in Zener card guessing tests. Among the experimental conditions, through fixed effects analysis, only the 'Placebo' one showed a significant effect (Estimate = 0.2048, p = 0.0184) with an increased likelihood of success (odds ratio = 1.227), suggesting that participants in this condition were more likely to correctly identify the Zener cards compared to the control condition. The limitations of the research are addressed in the discussion section.
Too Distracted to Remember: Does Attentional Disengagement Underlie the Photo-Taking Impairment Effect?
Authors: Croes Marc , Kreuwels Benedetta , Verheyen Steven
Published: May 2024

Research shows that when people take pictures of items around them, they have impaired memory for these items. Two theoretical accounts have emerged for this so-called photo-taking impairment effect: the offloading hypothesis and the attentional disengagement hypothesis. Given that previous studies seem to point towards the attentional disengagement hypothesis as the most plausible explanation, this study directly tested whether attentional mechanisms underlie the photo-taking impairment effect. One hundred and one undergraduate students observed, took a simple picture, and took the best possible picture (which increased the attentional demand) of fifteen paintings. After a filler task, their memory for visual details of the paintings was tested through a multiple-choice test. The results failed to show the photo-taking impairment effect, since participants recalled a similar number of visual details in each of the three conditions. These results also run counter to the attentional disengagement hypothesis in that the increased attentional demand did not yield a more pronounced memory impairment. A meta-analysis of the photo-taking impairment effect speaks to the heterogeneity of the effect and calls for future studies into the phenomenon’s generalizability and the circumstances under which it presents.
The problem of viewpoint III: Common ground
Authors: Maniatis Lydia Maria
Published: May 2024

In Part II of this series (Maniatis, 2024), I outlined a framework of structural constraints that appear to mediate the pictorial percept (and, by extension, the percept in general). I described three coordinate systems: that of the object, of the framework, and of the viewer's “visual frame,” arguing that the perception of shape and orientation reflects pressure to organize and align these three systems. The preliminary demonstrations and analysis presented there focussed on individual units (objects), rather than on collections of units. When we consider such collections, we observe the role of another structural feature, with its corresponding coordinate system: the plane on which figures appear to rest, or to be attached. This coordinate system, which plays the role of a subordinate frame, may be integrated into our account on similar principles.

Research on epistemic circularity has focused more on the problem of whether circular arguments are able to justify their conclusions rather than on the nature of circularity itself, and has kept a sharp delimitation from other types of circularities (logical, linguistic, and of definition). In this paper, I aim to move the focus toward the general concept of circularity, which I relate to the concept of ‘epistemic worry’. Through a brief overview on the known types of circularities, I show that circularity has multiple natures (not only that associated with its type), and the linguistic aspect is essential in qualifying a construct as circular, which in turn raises the problem of genuineness of a circularity. Within an extensional approach, I suggest generalizing the meaning of the key epistemological terms referred to in the classical definition of epistemic circularity to also cover additional associated concepts specific to other theoretical disciplines beyond epistemology.The proposed concepts and ideas are reflected in a structural unificatory account of circularity in terms of epistemic determination, which raises a challenge to the relational accounts of determination in regard to the transitivity of the determination relation.
Visual-Verbal Framing of Misinformation Messages: International, Regional and Cross-Persuasive Communication Perspectives
Authors: Dumitrescu Delia
Published: May 2024

We examine the visual-verbal framing of Covid-19 misinformation using a unique data set of 1500+ misinformation posts from more than 40 countries, as well as a dataset of 1500+ Covid-themed Facebook ads, collected from the US, Brazil and India. Using human coders and computer vision, we analyze the global and regional patterns of nonverbal emotional displays, blame attribution and emotional language in misinformation messages, and compare them with those used in ads. We find mostly similarities in the use of framing devices in misinformation across the world, but also some regional specificities. At the international level, several visual misinformation framing patterns emerge, including the association of images of politicians with visual displays of facial emotion. Moreover, misinformation posts and ads are revealed to use different visual-verbal framing strategies, with misinformation more likely to use visual-verbal incongruence and negative congruence, and Facebook ads more likely to use positive congruence.

تلعب تقنيات تحليل الانحدار اللامعلمي دوراً مركزياً في التحليل الإحصائي، حيث تعتبر طريقة انحدار شرائح الجزاء واحدة من أكثر الطرائق المستعملة حالياً لتمهيد البيانات، اذ يمكن من خلالها تقدير الدوال مباشرة من البيانات الصاخبة(التي  تحتوي على أخطاء) أو الملوثة (noisy data) بدلاً من الاعتماد على نماذج معلمية محددة، وتعتمد طريقة التقدير المستعملة لملائمه نموذج انحدار شرائح الجزاء في الغالب على طرائق المربعات الصغرى (OLS)، والتي من المعروف أنها حساسة للمشاهدات غير النمطية (المتطرفة)، في هذا البحث سيتم تقدير نماذج انحدار شرائح الجزاء (P-spline) المضافة المعممة باستعمال طريقة فصل المصفوفات الدقيقة المتداخلة (SOP) المقترحة من قبل الباحث (Rodríguez)، واخرون في عام 2015، والتي تأخذ المشاهدات المتطرفة في الاعتبار، حيث يعتمد التقدير على التكافؤ بين (P-spline) والنماذج المختلطة الخطية، ويتم تقدير معلمات التباين ومعلمات التمهيد بناءً على طريقة الإمكان الاعظم المقيد (REML). ومن اهم الاستنتاجات التي تم التوصل اليها عدم الحاجة الى استعمال طرائق التحسين العددي، كما يمكن دمج طريقة (SOP) بسهولة في تقدير النماذج المختلطة المضافة المعممة (GAMM) مع مجموعات التأثيرات العشوائية المستقلة، فضلاً عن سرعة تطبيق طريقة (SOP) في تنفيذ العمليات الحسابية.

The research aims to explore the impact of capital structure modeling on production business performance in order to arrive at a conclusion. Data were collected based on input from six Turkish cement producing companies. Analysis of the collected data was then used to achieve the goal. In the first part of the study, the concept of capital structure was explained, and the theories, namely the irrelevance theory, the trade-off theory (TOT), and their types, were discussed. The determinants of all capital structures and company-specific and capital structure models were also identified. The second part of the study was the practical part, where data on Turkish companies was used to achieve the goal. An input analysis of the capital structure of the selected sector was performed in order to generalize and clarify the conclusions regarding the capital structure of the analyzed companies. Where the main problem lies in determining the indicators of the capital structure that affect the performance of productive businesses. Performance was evaluated using economic value added (EVA) scale, correlation matrix, Cohen's scale, and SPSS.
We have developed some capital structure measures to investigate the links between these indicators and the overall performance of the organization. Correlation research results have shown significant improvements using regression analysis and principal components analysis to study the impact of certain unrelated elements on the overall success of the company. As a result, we recommend developing a new option that is willing to bear the risks associated with both options. The results of this study will serve as the basis for further research, including the collection of more relevant data and a further set of analyses.
Analysis of Interaction in the Case of No Replication in a Two-Factor Experiment

Published: May 2024

This research was concerned with the problem of interaction between effects in the data that can be arranged in two directions, which are called two-way classification models , in the absence of redundancy in the observations . The research was applied to a set of two -way classification data and used two methods to test the presence of interaction in the model , namely the Tukey test, which depends on one degree of freedom, and the Mandel test (a stack of lines) . The data included five levels of phosphorus and three levels of nitrogen in the wheat crop ; it can be seen in appendix A .
As a result , the Tukey and Mandel tests have a significant effect on nesting. The interaction effect had a clear and significant effect on the results of the analysis and the main effects tests .

The main task of safety and health at work (OSH) is to protect the most important thing we have, the health of each of us. Employers have the ability to anticipate and prevent risks by properly implementing an occupational health and safety management system.In connection with accidents at work, in recent years both in our country and around the world, permanent OSH management systems have begun to be used. The purpose of these management systems is to make occupational health and safety activities simpler, clearer and easier to implement in the workplace, to help create a more effective prevention system and to ensure the effective participation of all employees, regardless of their level in the enterprise structure. Thanks to this, it is possible to reduce the number of accidents at work and occupational diseases, to continue scientific research on occupational health and safety, and to create an environment that will help improve the level of development of the country. The purpose of this study is to demonstrate the benefits of OSH systems that can provide workers, businesses, and industries with ways to reduce occupational injuries and illnesses. For this purpose, a detailed review of the literature is conducted and the obtained results are comprehensively evaluated. The main task of the article is to describe the history of safety management systems to determine the state of implementation of the ISO 45001 system. Next, the article describes the ISO 45001 standard from the perspective of the PDCA Cycle and describes the benefits and importance of the implementation of the ISO 45001 standard.ISO 45001:2018 contains more requirements compared to previous editions of OHSAS standards. However, at the same time, it gives more freedom in their imple-mentation. The formulation of the standard can be considered a step forward ‒ it is clear and reflects the current situation in the business environment. Its structure is compatible with other management systems, in particular with the ISO 9001:2015 quality mana-gement system and the ISO 14001:2015 environmental management system. All three management standards have the same structure of sections, which allows you to create an integrated system of quality, environment, occupational health and safety management.The success of OSH management systems depends on the leadership, commitment and participation of all levels and functions of the organization; allocation of necessary resources, policies and goals in the field of occupational health and safety; compliance with legal and other requirements; effective management of safety risks; strict moni-toring; assessment of the effectiveness of the OSH management system; and integration of this system into the enterprise's business processes.Keywords: safety; management; ISO 45001; health; injuries, OSH
