Korkmaz, Meral; Uymaz, Muhammed
In recent years, the frequency and severity of floods have increased significantly due to the effects of global climate change, leading to serious economic and social losses, particularly in agricultural production areas. Floods not only damage cultivated lands but also negatively affect the livelihoods and socio-economic structures of local communities. This situation necessitates accurate identification of flood risk in agricultural areas and timely implementation of appropriate mitigation measures. In this study, flood risk was investigated in agricultural lands surrounding the Uluova Stream located between Doğankuş, Karşıbağ, and the Keban Dam and the İkitepe Stream, which flows through the center of Mollakendi in Elazığ Province, Türkiye. These areas are characterized by intensive agricultural activities. Using Geographic Information Systems (GIS), seven key parameters distance to streams, land use, aspect, slope, soil structure, precipitation, and geological features were analyzed, and corresponding thematic maps were generated. Flood risk levels were determined through spatial analysis and classification of these parameters using ArcGIS software. Based on the results, areas with high flood risk were identified, and both structural and non-structural mitigation measures were proposed for these zones. The findings offer valuable insights to support sustainable agricultural production and rural development by minimizing potential flood damages and reducing associated economic risks in the region.

Uyan, Umut; Ibin, Adil
The concept of quiet quitting, which denotes a cognitive and/or emotional, if not physical, detachment, has recently become one of the most frequently studied topics in organizational psychology. The term refers to performing only the tasks stipulated in job description with minimum organizational commitment and not going beyond that. Due to the detrimental effect of quiet quitting on both individual and organizational performance, it is crucial to study the phenomenon in depth. By referring to the organizational justice perspective, the study is designed to determine whether one of the negative employee experiences, nepotism, in local governments trigger quiet quitting. The main assumption of the research is that nepotism deteriorates the sense of justice, which leads employees to quit quietly. Structured questionnaires were administered to 259 local government workers in Adana. The results suggest that exposure to nepotism triggers quiet quitting in local governments where preferential treatments are allegedly pervasive. The study is expected to guide managers in establishing effective human resources practices in such institutions.

Karabacak, Volkan; Sançar, Taylan
This study provides a detailed mapping of active fault segments in Bursa and its surrounding regions, along with a comprehensive analysis of seismic behavior derived from paleoseismological data. As one of T & uuml;rkiyes' strategic economic centers with a dense population and industrial infrastructure, Bursa requires a holistic seismic risk assessment for effective disaster preparedness and mitigation. Paleoseismological analyses of the eastern segment of the Ulubat Fault indicate that it has been in a seismic quiescence period for approximately 1855 years. This prolonged period of inactivity highlights the potential for a large earthquake in the future around the Nil & uuml;fer Region of Bursa. Trench investigations conducted in Bursa city-centre reveal that the Bursa Fault has produced at least six surface ruptures over the past 12000 years, recurring approximately every 2000 years. Additionally, trench studies on the & Idot;neg & ouml;l Fault indicate that the & Idot;neg & ouml;l Fault has produced at least five surface ruptures over the last 12000 years, with the most recent major earthquake occurring more than 2500 years ago. Obtained results emphasize the potential for the Bursa and & Idot;neg & ouml;l faults to rupture simultaneously or in close succession, possibly triggering one another. Thus, the surface rupture caused by the 1855 Bursa earthquake is evaluated to have potentially triggered stress accumulation along the & Idot;neg & ouml;l Fault. This situation reveals a high probability of a surface-rupturing earthquake (M=6.2-6.9) occurring at any time on the & Idot;neg & ouml;l Fault, after 2500 years of seismic silence. Overall, these findings underscore the critical role of the faults in Bursa and its surroundings within the regional seismicity. In particular, the potential for sequential ruptures along the Bursa and & Idot;neg & ouml;l faults presents a significant earthquake hazard. This comprehensive analysis contributes to a deeper understanding of the seismotectonic dynamics of the region, providing valuable insights for seismic hazard assessment and risk mitigation efforts.

Barim, Esra; Gundogdu, Emrah
In this study, the P(N-vinyl carbazole-co-benzyl methacrylate) copolymer was synthesized, characterized by FT-IR/1H-NMR spectroscopic methods, and its composition was calculated from 1H NMR spectra. Composites of the copolymer with four different ratios of graphite (GR) and MAX phase (Ti3AlC2) by weight were prepared to obtain functional and novel electronic components for energy storage applications. Scanning electron microscopy, X-ray diffraction analyses were performed for some samples. Differential scanning calorimetry, thermogravimetric analysis curves were used to determine the thermal behavior of the materials. It was concluded that the composite with the highest glass transition temperatures and thermal stability was the composite with 10wt%GR/10wt%MAX additive. The thermal degradation kinetics of the copolymer and the composite containing 10wt%GR/10wt%MAX were investigated by applying the Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) methods and it was found that the thermal degradation activation energy of the composite was lower than that of the polymer. The dielectric properties of the materials were investigated at room temperature and between 0.1 kHz and 5 kHz. At 1 kHz the dielectric constants of the copolymer and 10wt%GR-doped composite were found to be 2.22 and 12.31, respectively. The composites doped with 10wt%GR and 10wt%GR/10wt%MAX were confirmed to be semiconductors.

In this study, the effectiveness of using cluster analysis in determining the changes in the number of animals in the field of goat and buffalo breeding in the TRB1 region was tested. The numbers of goats and buffalos used in the research were obtained from the records kept by TÜİK between 2004 and 2023. According to the cluster analysis results, the numbers of buffalos in Elazığ and Bingöl provinces was found to be higher than Malatya and Tunceli provinces between 2004 and 2023. According to the specified years, while Bingöl province was found to be higher than other provinces in terms of the numbers of goats, it was determined that Malatya province had the lowest values. When analyzed by year, the numbers of buffalos in the provinces of the TRB1 region for the years 2004-2006 was found to be higher than the following years. In other words, it is understood that the numbers of buffalos has been decreasing in the TRB1 region since 2007. In the TRB1 region, goat numbers between 2012-2023 were found to be higher than those between 2004-2011. Accordingly, it can be said that there has been an increase in the number of goats in the TRB1 region since 2012. In the TRB1 region, appropriate regulations need to be made, taking into account the differences between provinces and years in terms of the numbers of buffalos and goats. In this study, it was seen that cluster analysis could be used successfully in determining the differences in animal numbers according to provinces and years.

Ünal, İnan; Altın, Mustafa; Pandey, Shashikant
In this study, we consider various geometric conditions associated with the vanishing of a generalized curvature tensor, namely the T-tensor, on N(κ)-contact metric manifolds. We define and analyze several types of T-flatness conditions, including T-flat, ξ-T-flat, quasi-T-flat, and φ-T-flat structures. By applying these flatness conditions, we obtain algebraic constraints on the curvature parameters, particularly involving the Ricci tensor. The resulting characterizations allow for the classification of N(κ)-contact metric manifolds as either Einstein or η-Einstein, depending on the specific values of the structure constants. These investigations also lead to deeper insights into the geometric structure and local isometry types of the manifolds under study.

Derse, Onur; Polat, Elifcan Göçmen
Increasing solid waste amount arisen from the urbanization and population growth is an inevitable outcome in many countries. Solid waste has become one of the serious environmental problems and peculiar solid waste pathways are required to prevent contamination of environment. The optimal planning of the waste management should comprise the operations such as minimization, collection, landfilling and recycling of the waste. Also, location selection for landfill of municipal solid waste (MSW) is an effective step even essential, due to growing area shortage for waste disposal. In this respect, landfilling of MSW has been addressed in Tunceli, Turkey using an integrated approach. The Fuzzy Analytical Hierarchy Process (Fuzzy-AHP), a multi-criteria decision-making (MCDM) method, is utilized to decide the weights of the environmental, technical, economic, and social criteria regarding uncertainty. Then, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is conducted to rank the alternative landfill districts. Finally, the sub locations of selected district are mathematical modelled regarding transport cost, investment cost and demand with an integer linear programming model. The computational results indicate the proposed method effectiveness with a systematic approach by integrating MCDM and mathematical modelling.

Both pharmacological and material-based approaches aim to slow bacterial evolution toward resistance. In this context, imparting specific antibacterial properties to materials is essential. Traditionally, alloying was a method to equip entire metals with antibacterial features, such as incorporating small amounts of copper (Cu) and/or silver (Ag). However, due to the high cost and inherent limitations of alloying, surface modification processes have gained prominence. Recent antibacterial studies on copper have led to the application of Cu(Ag) electrochemical coatings on AISI430 steel surfaces. This study aims to combine copper’s antibacterial properties with enhanced corrosion resistance and surface hardness. The coatings were deposited using deep eutectic solvents, known for their environmentally friendly properties, followed by potentiodynamic analysis. Microstructural and phase distribution characteristics were examined through SEM-EDS analysis, while surface roughness was analyzed using profilometry. Transitioning from micro-disc electrodes to macro-scale AISI430 substrates, Cu(Ag) films containing 16% Ag demonstrated nanoscale roughness, approximately double the hardness, and superior corrosion resistance compared to conventional copper surfaces. Antibacterial tests compared the coated surfaces with untreated AISI430 steel. Results showed that Cu(Ag)-coated surfaces exhibited improved antibacterial properties. This study shows how Cu(Ag) electrochemical coatings can be used to make surfaces that are antibacterial, long-lasting, and resistant to corrosion.

Elephants have always been a focus of attention for humanity, thanks to both their physical structure and their potential strength. This attractive effect of elephants also made itself felt in the Ottoman Empire, and elephants took their place in Ottoman property from the early periods of the state. The elephants sent from the “Eastern” world to the Ottoman sultans within the scope of diplomatic relations now became permanent residents of the state. In fact, within the Ottoman Empire, positions such as chief elephant keeper and filbân (elephant caretaker) were created to care for and train elephants. The filbâns, whose numbers changed from time to time, worked under Mîrâhûr in the Ottoman state organization. The filbâns, who were paid salaries as ulufe, also routinely received allowances for the needs of the elephants. Shelters were provided for elephants in suitable areas in Istanbul. Elephants were not only found in Istanbul, but also in provincial cities, especially in Edirne. Elephants, who contributed to the authority and charismatic personality of the Sultan, were kept in the Ottoman Empire to serve different purposes. As a matter of fact, elephants appeared as important figures in the reception of ambassadors, festivals, wars and diplomatic relations between states. In this context, the subjects of this study were the actions that took place in the social, military and political life of the Ottoman Empire.
