An integrated decision-making framework to evaluate the route alternatives in overweight/oversize transportation
No full textOverweight and oversized transport (O&OT) has become one of the most critical elements of project logistics, driven by advancements in transportation and lifting technologies that now allow high-volume loads to be moved across long distances. This type of transportation operation, also called abnormal transportation, is greatly affected by technical factors such as the weight and geometry of the load, road surface, axle load limitations, slope, and ground strength, as well as external variables such as weather conditions, traffic density, and legal regulations. In planning and operational processes, Decision-Makers (DMs) and practitioners who plan and execute operations without adequately considering these factors and variables can lead to delays in operations, serious risks, and loss of productivity. This research proposes a flexible decision support model that integrates Step-wise Weight Assessment Ratio Analysis (SWARA) and Logarithmic Percentage Change-driven Objective Weighting (LOPCOW), and a ranking technique; i.e., Mixed Aggregation by Comprehensive Normalization Technique (MACONT) techniques to address the decision problems related to route selection, one of the most critical problems in transporting heavy and bulky loads, and to produce reasonable solutions. The proposed model significantly reduces information losses by processing subjective and objective information and integrating subjective (SWARA) and objective (LOPCOW) methods. Unlike traditional ranking approaches, the MACONT method combines three different normalization techniques to determine the ranking performance of alternatives. In this way, it provides more reliable and accurate results by reducing the deviations of the results provided by the single normalization technique. In addition, it shows each alternative's good and bad performance compared to the others and is more convincing about the results obtained. According to the results obtained by applying the proposed model, fuel consumption (0.096) is determined as the most effective and critical factor in selecting the route on which heavy and bulky loads will be transported. In this context, choosing routes that allow lower fuel consumption can contribute to reducing carbon emissions and external costs arising from transportation. The extensive robustness and validation check to test the proposed model prove that the proposed model is a reliable, robust, and practical decision-making tool for making reasonable and rational decisions in O&OT
The Johnson and Cook damage and flow stress model parameters of a rolled stainless steel 304 alloy
No full textPrevious studies on stainless steel 304 alloy (SS 304) have mostly focused on the stress-strain behavior as function of the volume fraction of deformation induced martensite and the applied strain and strain rate. Although equally important, the failure/fracture of this alloy has not been thoroughly investigated so far. In the present study, the Johnson and Cook (JC) damage model parameters of a rolled-SS 304 alloy, valid at a high strain rate (2900 s-1), were experimentally determined and numerically validated along with the JC flow stress parameters. The tensile failure strain of the alloy decreased as the strain rate increased from 10-3 to 10-1 s-1 and to 2900 s-1. Experimentally lower flow stresses at 2900 s-1 than at 1x10-3 s-1 were also found at the strains above 0.2, which was attributed to the adiabatic heating that declined the extend of the martensitic transformation at increasing strains. The determined damage and flow stress model parameters were further calibrated with the results of the numerical models of the quasi-static and high strain rate tension tests. Microscopic analyses and the hardness measurements on the untested and tested specimens confirmed the martensitic transformation and the highest hardness values were found in the specimens tested at 1x10-3 s-1. The martensite volume fraction as function strain rate until about necking strain (homogeneous deformation) was calculated and also microscopically determined using the electron back-scatter diffraction (EBSD) for the specimens tested at different strain rates. The results indicated the highest martensite volume fraction in the specimens tested at 10-3 s-1 (0.55-0.6) and the lowest in the specimens tested at the high strain rate (0.27-0.30). An agreement between the calculated and the EBSD determined martensite volume fractions was shown for the studied alloy.Scientific and Technological Research Council of Turkiye (TUBITAK) [221M417]This work has received funding from the Scientific and Technological Research Council of Turkiye (TUBITAK) under 1001-TUBITAK with the grant agreement of 221M417

“BUDGET MONITORING AND SMART LOGISTICS MANAGEMENT SYSTEM” (BI?S-ALYS) TO ELIMINATE WASTE IN PUBLIC SECTOR
No full textBu çalışmada, kamu kaynaklarının israf edilmesine neden olan faktörler ile bu israfın ekonomik etkileri incelenmiştir. Öncelikle israf olgusunun nedenleri ve sonuçları açıklanmış, ardından kamu sektöründeki israfın boyutları değerlendirilmiş ve bu sorunun giderilmesine yönelik çözüm önerileri sunulmuştur. Kamu sektöründeki israf, ülkelerin hem makroekonomik hem de mikroekonomik dengelerini tehdit eden önemli bir sorundur. Bu nedenle, pek çok ülkede ciddi bütçe açıkları ve artan kamu borçları gözlemlenmektedir. Söz konusu bütçe açıkları ise ekonomik kırılganlıkları daha da derinleştirmektedir. Bu sorunun giderilebilmesi için kararlı bir kurumsal duruş sergilenmeli; süreç yönetimine ilişkin prosedürler açık ve net biçimde tanımlanarak dijital bir sistem üzerinden uygulanmalıdır. Standartlaştırılmış kamu prosedürleri, kamu personelinin görev ve sorumluluklarının daha iyi anlaşılmasını sağlayacak; bu da görevlerin etkin biçimde ifa edilmesine katkıda bulunacaktır. Böylece kamuya ait tüm taşınır ve taşınmaz varlıklar kayıt altına alınabilecek, etkin bir izleme sistemiyle yolsuzluk, usulsüzlük ve israf gibi olumsuzlukların önüne geçilebilecektir. Ayrıca kamuya ait binalar, araçlar, ekipmanlar, işgücü, finansal kaynaklar ve sarf malzemelerinin daha verimli kullanılabilmesi için kurumsal süreçlerin dijitalleşmesi büyük önem taşımaktadır. Hem Türkiye'de hem de diğer ülkelerde, kamu sektöründeki israfı önlemeye yönelik geliştirilecek sistemler; mali disiplinin sağlanması ve ekonomik istikrarın korunması açısından kritik bir gereklilik olarak değerlendirilmektedir. Bu doğrultuda yapılacak araştırma ve projeler, makro ve mikro ekonomik problemlerin çözümünde öncelikli bir yere sahiptir. Bu çalışmada, Bartın Üniversitesi bünyesinde geliştirmiş olduğumuz ve aktif olarak kullanılmakta olan kamu kurumlarının taşınır ve taşınmaz envanterlerini dijital olarak kayıt altına alan, kurumlar arası ihtiyaç eşleştirmesi yapan, mükerrer alımları önleyen ve harcamaları izlenebilir kılan otonom bir yazılım sistemi “Bütçe İzleme ve Akıllı Lojistik Yönetim Sistemi (BİS-ALYS)” örneğinin yapısı, gelişimi, işleyişi ve katkıları ele alınmıştır. Anahtar Kelimeler: Kamu İsrafı, BİS-ALYS, Kamu Verimliliği, Dijital Lojistik, Bütçe Disiplini, İktisadilikABSTRACT In this study, the factors that cause waste of public resources and the economic effects of this waste are analyzed. Firstly, the causes and consequences of the wastefulness phenomenon are explained, then the dimensions of wastefulness in the public sector are evaluated and solution proposals are presented to eliminate this problem. Waste in the public sector is an important problem that threatens both macroeconomic and microeconomic balances of countries. Therefore, serious budget deficits and increasing public debt are observed in many countries. These budget deficits further deepen economic vulnerabilities. To address this problem, a decisive institutional stance should be taken and procedures for process management should be clearly defined and implemented through a digital system. Standardized public procedures will provide a better understanding of the duties and responsibilities of public personnel, which will contribute to the effective performance of their duties. Thus, all movable and immovable assets of the public sector can be recorded and corruption, irregularities and waste can be prevented through an effective monitoring system. In addition, digitalization of institutional processes is of great importance for more efficient use of public buildings, vehicles, equipment, workforce, financial resources and consumables. Both in Türkiye and in other countries, the systems to be developed to prevent waste in the public sector are considered a critical requirement for ensuring fiscal discipline and maintaining economic stability. Research and projects to be carried out in this direction have a priority place in solving macro and micro economic problems. In this study, the structure, development, functioning and contributions of “Budget Monitoring and Smart Logistics Management System (BIS-ALYS)”, an autonomous software system that digitally records the movable and immovable inventories of public institutions, makes inter-institutional needs matching, prevents duplicate purchases and makes expenditures traceable, which we have developed within Bartın University and is actively used, are discussed.

Tarihsel Sürekliliğiyle Kudüs Şam Kapısı'nda Değişim ve Direnç (Kent Kimliği, Yönetsel Eylemler ve Çatışmalar)*
No full textThis article aims to analyze the historical and modern transformations of the Damascus Gate in Jerusalem, focusing particularly on the urban planning projects and social interactions that occurred during the British Mandate period. Spanning from the Ottoman era to the British Mandate, the study examines changes in the physical and social structure of this site within the framework of collective memory, identity, and modernity. The article adopts Richard Sennett’s theoretical framework on urban spaces and public areas. Sennett’s critique of the weakening of social functions and the rise of individualism in public spaces under modernity provides an analytical foundation for understanding the transformations of the Damascus Gate. Through a review of literature, historical documents, and periodical press sources, the article investigates how the spatial changes around the Damascus Gate during the British Mandate period impacted social solidarity, identity, and resistance. The study demonstrates that urban modernization and Western-oriented city planning projects implemented during the British Mandate sought to weaken the historical functions of the Damascus Gate. However, despite the emergence of modern consumer culture and spatial transformations, the Damascus Gate has continued to serve as a powerful symbol of social solidarity, resistance, and collective memory for the Palestinian community. The Damascus Gate is a site of tension between modernity and tradition, highlighting efforts to preserve its social and cultural significance. The central research question of the article is formulated as follows: “As a historical public space, how has the Damascus Gate sustained or lost its functions as a site of social solidarity, collective memory, and resistance amid transformations driven by modernity, consumer culture, and urban planning projects during the British Mandate period? ” This question offers a theoretical discussion on modern urban spaces’ social and cultural functions. The spatial reorganizations around the Damascus Gate during the British Mandate period deeply influenced the social and cultural context of the area. Richard Sennett’s critiques of how modern urban planning disrupts social bonds provide a valuable framework for understanding the transformation of the Damascus Gate during this period. In this context, the article explores not only the physical transformations of the site but also their profound effects on collective memory, solidarity, and resistance. © 2025 Elsevier B.V., All rights reserved
Cognitive traces of life kinetic exercise in puberty sedentary subjects
No full textIn this study, it was aimed to reveal the effect of regular life kinetic exercises on the concepts of motivation and imagery in sports in puberty period individuals. In the study in which pre-test-post-test control group design was used, 44 students (experiment = 22, control = 22) who were continuing their education in a state secondary school and selected by appropriate sampling method participated. The Personal Information Form, Motivation Scale in Sport and Imagery Inventory in Sport were used as data collection tools. The collected data were analysed using repeated measures analysis of variance. When the results were analysed, it was determined that there were statistically significant differences in the pre-test and post-test mean scores of motivation and imagery in sport. As a result, it can be stated that the life kinetic exercise protocol applied for 8 weeks in sedentary individuals positively predicted motivation and imagery parameters in sports. This result indicates that the related psychological phenomena, which are as important as sport performance in sports, can be positively affected by cognitive and motoric exercise combinations
Phosphate recovery from digestate using magnesium-modified fungal biochar
No full textMg-rich biochars have been used for the removal and recovery of phosphate (PO43-) and ammonium (NH4+) from waste streams. In this study, a novel magnesium-modified biochar (Mg-FBC) was synthesized by immobilizing waste magnesite dust (WMD) into Aspergillus niger fungal biomass for the adsorption of PO(4)(3- )and NH4+. Pyrolysis at various temperatures and analysis using techniques such as SEM-EDS, TGA, XRD, FTIR, and BET revealed that biochar produced at 650 degrees C (Mg-FBC650) exhibited enhanced surface properties favorable for effective adsorption. This improvement is attributed to the increased surface area facilitated by the hyphal structure of A. Niger and the effective dispersion of MgO on its surface. In experiments using a synthetic phosphate solution, the adsorption capacity reached 595 mg PO43-/g BC, fitting the Langmuir model at pH 9. In addition, experiments with the liquid fraction of a real digestate (LFD) showed adsorption capacities of 502 mg PO43-/g BC and 150 mg NH4+/g BC, respectively. The adsorption mechanism was elucidated through SEM-EDS, XRD, and FTIR analyses confirming that Mg-FBC650 facilitates a multifaceted adsorption mechanism, including adsorption, electrostatic attraction, chemical precipitation, and surface complexation. Consequently, PO43- was the primary adsorbate in the synthetic solution, while both PO43- and NH4+ were effectively removed from the LFD, indicating that Mg-FBC650 has substantial potential as an efficient adsorbent for nutrient removal. As a result, Mg-FBC650 is believed to hold significant potential as a slow-release and readily transferable bio-fertilizer, particularly suitable for application in soils deficient in organic matter, nitrogen, and phosphorus.

Unmasking the Relationship Between Cyber Dating Abuse and Fear of Intimacy: Insights From a Cross-Sectional Study of Undergraduate Students
No full textThe increasing digitalization of the world has led to a rise in cyber dating abuse among undergraduate students, who are transitioning into young adulthood and will be part of the future workforce. Additionally, identifying the less-studied issue of fear of intimacy in this context is crucial. This study aims to examine the relationship between cyber dating abuse and fear of intimacy among undergraduates. Conducted as a cross-sectional study, it involved undergraduate students from all university faculties using proportional stratified sampling with an online survey (n = 416). Data were collected via a Personal Information Form, Cyber Dating Abuse Scale, and Fear of Intimacy Scale. Analyses included Pearson correlation, t-tests, ANOVA, and post hoc (Tukey, LSD) tests, and multiple regression analyses. A significant relationship was found between students' levels of cyber dating abuse and fear of intimacy (p < .001), indicating that as cyber dating abuse increases, so does fear of intimacy. Factors such as gender, faculty, smoking, romantic relationship status, and duration of relationship were found to influence these levels. Male students reported higher scores for both experiencing and perpetrating cyber dating abuse compared to females, who had higher fear of intimacy scores. Students in romantic relationships experienced and perpetrated more cyber dating abuse (p < .05). Longer relationship durations were associated with increased monitoring and controlling behaviors. Smokers showed a positive correlation between cyber dating abuse and fear of intimacy (p < .05). The significant relationship between cyber dating abuse and fear of intimacy found in this study highlights the need for interventions. University-targeted programs should be developed to address these issues, and public health nurses should conduct awareness and educational programs to prevent such abuse
Importance of Soil Moisture Sensor Data in Flood Early Warning Systems
No full text9th International Symposium on Innovative Approaches in Smart Technologies, ISAS 2025 -- Gaziantep -- 211342Soil moisture data is crucial for improving the accuracy of flood early warning systems. The Bartin Basin includes three main tributaries feeding the Bartin River. Soil moisture data stations have been established, distributed homogeneously across these areas. The soil moisture information obtained from these stations indicates how much water the soil contains during rainy weather. Each data station is equipped with three moisture sensors. These sensors are placed at depths of 20 ?cm , 40 ?cm, and 80 cm within the soil. This setup aims to monitor the moisture content in the upper, middle, and lower soil layers in real time. The sensors at three different depths also enable the calculation of the infiltration rate of rainwater into the soil. Within the scope of this study, soil moisture data stations were installed at 32 pre-identified locations. During the installation of each station, soil samples were collected from the respective areas. These samples were analyzed in a laboratory environment, serving both to calibrate the moisture sensors and to determine the physical properties of the soil in those regions. The data obtained from the soil moisture stations were used as input for a developed hydrological model, with the aim of enhancing the model's accuracy. The hydrological model will be operated on a central server established at the Kutlubey Campus of Bartin University. To transmit the IoT data collected from the soil moisture stations to the central server, 4 G modems were employed. With the goal of ensuring a more sustainable operation, the soil moisture stations were designed to meet their energy needs through solar power. The energy requirement of each station is approximately 29 Wh, and the total energy storage capacity has been established at 960 Wh. © 2025 Elsevier B.V., All rights reserved
