Background Combat athletes face unique psychological demands, and stress may influence both their cognitive experiences and psychological well-being. This study aimed to examine the mediating role of mental fatigue awareness in the relationship between perceived stress and psychological well-being among combat athletes, thereby contributing to a clearer understanding of a potential cognitive mechanism linking stress to well-being in this population.Methods A total of 303 combat athletes voluntarily participated. Participants completed the Perceived Stress Scale, Mental Fatigue Awareness Scale, and Psychological Well-being Scale. Statistical analyses assessed the direct effects of perceived stress on psychological well-being, the effect of stress on mental fatigue awareness, and the potential mediating role of mental fatigue awareness.Results Perceived stress significantly increased mental fatigue awareness (b = 0.732, SE = 0.064, beta = 0.549, p = 0.001) and directly decreased psychological well-being (b = - 0.488, SE = 0.166, beta = - 0.191, p = 0.004). Mental fatigue awareness negatively affected psychological well-being (b = - 0.374, SE = 0.124, beta = - 0.195, p = 0.003) and partially mediated the relationship between stress and well-being (indirect effect: b = - 0.274, SE = 0.115, beta = - 0.107, p = 0.003; 95% CI = - 0.504 to - 0.049).Conclusion Perceived stress was associated with psychological well-being both directly and indirectly through increased mental fatigue awareness. These findings suggest that mental fatigue awareness may represent a relevant cognitive pathway linking stress perceptions to well-being. Accordingly, stress management and strategies aimed at regulating mental fatigue may be considered as potentially beneficial components in efforts to support psychological well-being among combat athletes.

The growing interest in natural products, particularly as food additives and pharmaceutical raw materials, is making research into discovering new sources especially important. Erodium cedrorum subsp. salmoneum (family Geraniaceae) is used traditionally to cure many ailments like diabetes and gastro-intestinal diseases. Within this background, the current study was designed to investigate, for the first time, the chemical composition, antioxidant and enzyme inhibitory poroperties of different extracts from the aerial parts and roots of E. cedrorum. Results revealed that the aqueous extract of the aerial parts accumulated the highest total phenolic (85.35 mg GAE/g) and flavonoids (28.65 mg RE/g) contents. A total of 61 and 45 compounds, belonging mainly to phenolic acids and flavonoids, were tentatively identified in the aerial parts and roots extracts respectively. The aqueous extract from the aerial parts exerted the highest antiradical, ions reducing and chelation properties. The EtOH and 70% EtOH extracts of the two organs recorded the best anti-acetylcholinesterase activity (2.18 -2.41 mg GALAE/g; p >= 0.05) while those of the roots recorded respectively the best anti-butyrylcholinesterase and antityrosinase activities. The most potent antibacterial activity was exhibited by the 70% EtOH extracts from aerial parts and the pure EtOH extracts from roots. In contrast, ethyl acetate extracts from both plant parts showed only marginal activity. Among the tested strains, the highest susceptibility was observed against C. sporogenes ATCC 19404, C. bifermentans ATCC 638, S. aureus ATCC 6538, S. aureus ATCC 43300 (MRSA), C. diphtheriae PCM 506, and H. pylori ATCC 43504. The extracts were also examined for their anti-cancer potential on the HeLa, AGS and SKOV-3 cell lines, as well as a non-cancerous cell line. The ethyl acetate extract of the roots exhibited the most potent anti-cancer activity, with the lowest IC50 values. In addition, selected top-ranked complexes against AChE, alpha-amylase, representative bacterial and oncogenic targets were further evaluated by molecular docking and 100 ns molecular dynamics (MD) simulations, indicating overall conformational stability and persistent binding. In conclusion, these results position E. cedrorum as a valuable natural source of antioxidant and enzyme-inhibitory agents, meriting further exploration for drug development purposes.

Erol, Ismail; Dogru, Tarik; Oztel, Ahmet; Bilgihan, Anil; Peker, Iskender; Neuhofer, Irem Onder
The primary perspective of this study is the global tourism industry (GTI) as an interconnected supply chain network, encompassing both tourism firms (e.g., hotels, airlines, and operators) and destinations (e.g., local communities and ecosystems). This industry-level focus allows for analyzing resilience indicators that bridge firm-specific capabilities with destination-wide vulnerabilities, rather than isolating one over the other. Using a mixed-method approach, this research conceptualizes resilience through various management theories. First, it identifies critical resilience indicators across institutional, societal, economic, and ecological dimensions. Second, these indicators are analyzed with a novel Spherical Fuzzy Interpretive Structural Modeling and Cross-Impact Matrix Multiplication Applied to Classification framework, utilizing expert opinions to uncover complex interdependencies among indicators. The findings of this study highlight that effective government policies, robust incentive mechanisms, advanced digital infrastructure, dynamic capabilities, and ecologically sustainable tourism practices are key drivers of resilience. However, socioeconomic impacts, tourist satisfaction, and price competitiveness emerge as highly dependent outcomes influenced by these drivers. This study also introduces the Adaptive Global-Local Interaction Theory, a new framework that integrates global influences with local realities to enhance tourism resilience. By offering a comprehensive framework and practical guidelines, this research equips policymakers and stakeholders with actionable strategies to bolster the industry's capacity to anticipate, adapt to, and recover from crises, promoting sustainable development amidst volatile global conditions.

Acer, Niyazi; Palanci, Ozgur; Ipekten, Funda; Erdogan, Furkan Mert; Yarar, Burhan; Ozyasar, Ali Faruk
Objective:Accurate volume measurements of subcortical brain structures are essential in neuroimaging studies. This study aimed to compare two automated segmentation algorithms, 3D Slicer and VolBrain, for subcortical brain volumetry. Method:Subcortical volume measurements obtained using 3D Slicer and VolBrain were compared using the Neurofeedback Skull-stripped (NFBS) dataset. Statistical analyses included the coefficient of determination (R2) and Bland-Altman (B-A) plots. Volumetric measurements from both tools were evaluated across multiple subcortical brain regions. Results:Strong agreement was observed for the caudate nucleus, thalamus, and hippocampus, while notable discrepancies were identified in the amygdala, globus pallidus, and nucleus accumbens. Both constant and proportional systematic errors were detected in certain regions, with greater variability observed in 3D Slicer measurements. Intraclass Correlation Coefficient (ICC) analysis demonstrated weak agreement for the accumbens and amygdala, and moderate agreement for the hippocampus and thalamus, highlighting region-specific differences in performance Conclusion:Both VolBrain and 3D Slicer are effective tools for subcortical brain volumetry. VolBrain provides a fully automated workflow, whereas 3D Slicer allows greater flexibility through detailed corrections. Method selection should be guided by research objectives, regions of interest, and image quality. Further validation across diverse datasets is warranted to improve clinical applicability, particularly in regions showing lower agreement.

Modjarrad, Monir; Uysal, Ibrahim; Yara, Irfan O. M. A.; Sen, Ahmet Dundar; Xin, Guangyao; Müller, Dirk
We present an integrated petrological, mineral-chemical, whole-rock geochemical, microstructural, and phase-equilibrium study of the West Maku metamafics (WMM), an ophiolite-related mafic unit in NW Iran. The WMM comprises garnet amphibolites and amphibole-bearing high-grade metamafic rocks containing almandine-rich garnet, tschermakite-ferro-tschermakite, andesine, epidote/zoisite, annite, muscovite-phengite, spinel, ilmenite, chlorite, quartz, and K-feldspar. Immobile element systematics indicate a tholeiitic, MORB-like basaltic protolith; LILE and crust-sensitive element enrichment likely reflect inherited crustal/sediment-derived components and metamorphic redistribution during subduction-accretion and/or m & eacute;lange assembly. P-T modelling defines four relative stages: M1, upper greenschist-facies metamorphism at ca. 6.4 kbar and 360 degrees C; M2, prograde heating to 8.0-8.4 kbar and 700-720 degrees C; M3, peak upper-amphibolite- to granulite-facies conditions at 9.0-9.8 kbar and up to 810 degrees C, with localized anatexis; and M4, retrogression at ca. 3.8 kbar and 520 degrees C. The clockwise path records the burial and heating of MORB-derived crust in a subduction-accretionary setting, followed by collision-related thermal relaxation/crustal thickening and subsequent uplift. Regional comparisons indicate thermally heterogeneous evolution along the central Neo-Tethyan suture across Armenia, SE T & uuml;rkiye, NE Iraq and NW Iran.

Salah, Mohamed K.; Alkan, Hamdi; Öztürk, Serkan; Güney, Recep
On February 6, 2023, two destructive earthquakes and many posterior aftershocks hit the Kahramanmaras,area in southern Anatolia. The Kahramanmaras, earthquake sequence (KMES) caused extensive damage and economic losses in T & uuml;rkiye and Syria. In this study, the 3-D crustal seismic velocities surrounding the hypocentral region of the KMES are determined using a large dataset of body wave arrival times obtained from local earthquakes. To better constrain the physical properties and seismogenic behavior of the KMES source region, the Vp/Vs ratio is calculated and correlated with Poisson's ratio using the obtained velocity models. To gain a better understanding of the stress conditions and regional earthquake activity in the study area, the depth variation of the b-value is also examined. The velocity structure is generally heterogeneous with both low and high velocities at upper crustal depths. Along the East Anatolian Fault Zone and its environs, low-velocity anomalies are charted. Also, small b-values (<1.0) are estimated in the region encompassing the KMES, especially at upper crustal depths. The KMES source zone is characterized by low b-value, low to average Vp, low Vs, and average/high Vp/Vs ratios. Hit count rates and the resolution test show that the mapped velocity anomalies are robust down to a depth of 45 km. Therefore, the moderate/high Vp/Vs and small b-values at the upper and middle crustal depths along the EAFZ may give constraints on the next earthquake hazards of the study region. The present findings provide deeper insight into the physical properties and the seismogenic potential of the crustal zones in proximity to the active fault segments of the Anatolian Plateau and the northwestern part of Arabia.

Spices and herbs are vital flavoring agents in food. However, they are particularly vulnerable to microbial contamination primarily due to their open production environments and low water activity, which enhances microbial resistance to conventional pasteurization. In addition, traditional decontamination methods often struggle to balance microbial safety and product quality. This review aims to deliver valuable insights into innovative technologies designed for improving microbial safety and overall quality of spices and herbs while fostering advancements in the industry. This review comprehensively summarizes the principles, applications, and influencing factors of emerging thermal technologies (e.g., radio frequency heating, superheated steam, and vacuum steam) and non-thermal technologies (e.g., ethylene oxide, chlorine dioxide, cold plasma, and ionizing irradiation). Furthermore, it critically discusses the current limitations of these technologies and proposes strategies for future advancements. Novel decontamination technologies show promise in improving microbial safety and preserving the quality of spice and herb products. In particular, radio frequency and chlorine dioxide technologies emerge as promising options for spice decontamination due to their better ability to balance microbial control efficiency and quality retention. Further research should focus on optimizing parameters through models, developing combination technologies, and promoting pilot test verification to facilitate industrial application.

Aydin, Faruk; Oguz-Saka, Simge; Karsli, Orhan; Dokuz, Abdurrahman; Moghadam, Hadi Shafaii; Zhao, Junxing; Schmitt, Axel K.
Understanding melt source evolution during arc-back-arc magmatism is essential for resolving crustal growth processes and the development of felsic-hosted volcanogenic massive sulfide (VMS) systems. Here we integrate new zircon HfO isotope data with published geochronological and whole-rock geochemical datasets to reassess the petrogenesis of Late Cretaceous arc and back-arc magmatic flare-ups in the eastern Sakarya Zone (ESZ), NE T & uuml;rkiye. Two high-flux magmatic episodes are recognized: a Turonian-Santonian pulse (similar to 92-86 Ma) forming the lower volcanic sequence (LVS), and a younger Campanian pulse (similar to 84-75 Ma) forming the upper volcanic sequence (UVS), accompanied by contemporaneous arc-related granitoids. Zircons from both LVS and UVS display predominantly positive epsilon Hf(t) values (+2 to +12) coupled with mantle-like delta O-18 (5.0-5.6 parts per thousand), but contain abundant inherited Mesoproterozoic-Paleozoic cores and show variable two-stage model ages (T-DM (c) = 0.4-1.4 Ga). Together with the peraluminous affinity of many felsic units, these features indicate that the dacite-rhyolite suites hosting VMS deposits were generated by melting of compositionally heterogeneous lower crust variably hybridized by juvenile basaltic inputs. Arc granitoids likewise record a transition from dominantly juvenile, I-type magmatism during the Coniacian-Santonian to more evolved, crust-influenced signatures during the Campanian. We propose that both flare-ups reflect repeated episodes of basaltic underplating and deep-crustal heating, producing voluminous felsic magmas capable of sustaining long-lived hydrothermal systems. The spatial and temporal coincidence between felsic-dominated flare-ups and VMS mineralization suggests that hybridized felsic magmas, rather than purely juvenile mantle melts, played a central role in generating the physiochemical conditions required for metal-bearing hydrothermal fluids in the ESZ.

The development of effective acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors remains a crucial objective in the treatment of neurodegenerative diseases, including Alzheimer's disease (AD). In this study, a novel synthetic approach was established to prepare a series of diaryl-substituted tacrine derivatives. Initially, brominated aminobenzonitrile was subjected to Suzuki-Miyaura cross-coupling reactions with various aryl boronic acids to yielding diaryl-substituted aminobenzonitriles at yields of 60%-72%. These intermediates were then cyclized with cyclohexanone and cycloheptanone under Friedl & auml;nder conditions using BF3 & centerdot;OEt2 as a catalyst, affording six- and seven-membered diaryl tacrine analogues in yields of 52%-68%. All synthesized compounds were characterized by NMR, IR, and elemental analysis. The inhibitory activities of these compounds (7-16) against AChE and BChE were evaluated, and several analogs demonstrated potent dual-enzyme inhibition at nanomolar concentrations. Notably, compounds 8 and 13 exhibited half maximal inhibitory concentration (IC50) values of 6.848 and 8.545 nmol/L for BChE, respectively, indicating strong potential as selective cholinesterase inhibitors. The structure-activity relationship (SAR) analysis revealed the influence of aryl substituents on the potency and selectivity of enzyme inhibition. Compared to previously reported tacrine derivatives, the newly synthesized analogs exhibited superior inhibitory profiles, indicating their potential as lead compounds for further development in AD therapeutics.

This study aimed to examine match running performance (RP) in professional soccer teams in terms of success variables. A total of 626 observations obtained via a multicamera tracking system (InStat Ltd.) from a total of 323 matches played by 19 teams in the Turkish Super League (TSL) during a season were analyzed. The success of the teams was examined as two different independent variables: i) according to the endof-season final table ranking (1st rank: the first five teams that have qualified for the European League; 2nd rank: the second rank five teams; 3rd rank: the third rank five teams; and 4th rank: the four relegated teams). ii) According to the match outcome (win, draw, loss). The RP variables included total distance (TD), covered distance in five speed zones (walking, jogging, running, high-speed running (HSR) and sprinting), high-intensity acceleration (HIA) and maximum acceleration. ANOVA and post hoc tests revealed that 1strank teams were significantly more common in running, HSR, sprinting and acceleration (p < .05). There was no difference between the TD groups (p > .05). The TD, walking sprinting and max. acceleration values of the winning teams were greater (p < .05). The short-term success goal for teams is to win a match or score a point, and the long-term goal is to be at the top of the final table in the season. Therefore, the current research revealed that high-intensity RPs and high intensity acceleration in matches are especially decisive in the success of teams.

Akyol, Mehmet; Zuhal, Mustafa; Mete, Emrullah; Lorente, Daniel Balsalobre; Barut, Abdulkadir
The agricultural sector plays a vital role in ensuring food security and supporting sustainable economic growth. However, climate change and global warming pose significant challenges to the long-term viability of agricultural production, underscoring the need for sustainable agricultural practices. Adopting clean technologies and environmentally responsible policies is essential for balancing economic and agricultural sustainability while minimizing ecological harm. Supportive and protective agricultural inputs are widely used to enhance productivity, yet excessive, unregulated use can lead to environmental degradation. This deterioration negatively impacts ecosystems, reducing biodiversity and straining natural resources. The Load Capacity Factor (LCF) serves as a critical metric for assessing the environmental footprint of agricultural activities. This paper investigates the effects of agricultural value-added, pesticide use, and fertilizer application on LCF in BRICS-T countries. The findings indicate that these variables exhibit long-term cointegration, with varying short- and long-term impacts. To ensure the sustainability of agricultural production while safeguarding ecosystems, it is essential to integrate clean technologies, precision farming, and regenerative agricultural practices into policy frameworks. Sustainable agricultural systems and environmentally conscious policies are fundamental to securing resilient food production and long-term economic stability.

The Simav Fault Zone (SFZ) in Western Anatolia remains one of the most active tectonic regions in Turkey, and the 2025 S & imath;nd & imath;rg & imath; earthquake swarm has renewed concern regarding evolving seismic hazard. This study analyzes the swarm on the S & imath;nd & imath;rg & imath; Segment using Coulomb stress modelling, spatial distributions of b- and p-value, gravity and magnetic anomalies, geothermal data, and GNSS observations. Coulomb stress calculations show that the M-W = 6.1 and M-W = 6.0 mainshocks produced stress increases of similar to 0.1 bar that effectively loaded adjacent segments of the SFZ, D & uuml;vertepe Fault Zone (DFZ), and Gelenbe Fault Zone (GFZ), guiding the east-southeast and northward migration of aftershocks. Spatial statistics indicate a b-value ranging from 0.6 to 1.3 and a p-value between 0.3 and 1.0. The lower b-values (< 1.0) and p-values (< 0.5) mark high-stress regions near the mainshock, and higher values characterize more stable zones. Gravity anomalies delineate a dense volcanic-ophiolitic body in the southwest and a caldera-like depression south of the SFZ, while magnetic anomalies highlight the structural continuation and interaction of the SFZ with the GFZ. GNSS stations recorded centimetre-to millimetre-scale motions: BAL1 moved similar to 1.34 cm horizontally with minor uplift, DEI1 experienced similar to 1.12 cm displacement with small vertical fluctuations, and KIKA shifted similar to 0.85 cm southwestward with largely stable elevation. Together, these results show that the 2025 swarm was controlled by stress transfer within a mechanically heterogeneous tectonomagmatic system. The identified stress-enhanced corridors along the SFZ and DFZ may act as future nucleation zones, emphasizing the need for sustained monitoring of this evolving fault network.

Büyük, Ersin; Hacioglu, Ozlem; Ayzit, Tolga; Baba, Alper
Enhanced Geothermal Systems (EGS) provide firm, low-carbon baseload power and can contribute to reducing fossil-fuel-based energy generation. Granites and granitoids are particularly favourable EGS hosts due to their widespread occurrence, fracture-controlled permeability, and long-term heat supply from radiogenic decay. This study proposes an EGS development plan for the Kestanbol Granitoid Intrusion (KGI) in NW Anatolia, T & uuml;rkiye, based on a three-dimensional magnetotelluric (MT) model integrated with geochemical constraints on radiogenic heat production (RHP). We invert MT data acquired at fifty unevenly spaced sites to image the 3D resistivity structure of the KGI and its surroundings, resolving a highly resistive plutonic body bounded by relatively conductive fault-fracture zones. To quantify the radiogenic heat reservoir, we determine RHP rates from uranium, thorium, and potassium concentrations measured on twenty-seven rock samples from the KGI and adjacent lithologies, and integrate these values with the MT-derived pluton geometry. When combined with the regional stress regime, the integrated results indicate that the KGI hosts elevated RHP relative to surrounding rocks and that its internal structure and fault-controlled permeability architecture are favourable for EGS development. In particular, the north-western margin of the KGI emerges as the most promising target for injection-production well pairs. This workflow demonstrates how integrated MT, geochemical, and structural analyses can provide a quantitative, site-specific basis for EGS prospect ranking and drilling strategy in radiogenic granite/granitoid provinces. Overall, we propose a site-specific and risk-aware EGS development plan for the KGI that couples subsurface structure, radiogenic heat supply, and permeability architecture, providing a transferable framework for assessing radiogenic granite/granitoid provinces.

This study examines how T & uuml;rkiye's National Polar Science Programme (NPSP) and the National Polar Science Symposium (NPSS) define and implement public engagement within the country's emerging polar research framework. Situating T & uuml;rkiye's experience within broader international debates on public engagement in emerging and internationally governed scientific domains, the analysis draws on core science communication theories, including deficit-dialogue-participation models, typologies of public engagement, and co-production perspectives. Methodologically, the study employs qualitative document analysis of ten NPSP Monitoring and Assessment Reports (2018-2022) and seven NPSS abstract books (2017-2023), using an iterative and theory-informed coding process. The findings indicate that public engagement is predominantly shaped by informational and visibility-oriented strategies, while dialogic elements are gradually emerging through education- and youth-focused initiatives. However, institutionalised participatory mechanisms enabling public influence on research agendas remain limited. The study concludes that T & uuml;rkiye's public engagement trajectory reflects a hybrid and incremental configuration shaped by institutional development within an internationally governed research context. By treating the Turkish case as an analytically comparative example rather than a context-specific exception, the article contributes to international discussions on how public engagement is structured and institutionalised in emerging polar and climate research programmes.

This article examines T & uuml;rkiye's participation in the Second International Polar Year (IPY-II, 1932-1933) as a historically grounded and underexplored case of early science diplomacy. IPY-II coordinated interdisciplinary polar research across forty-four countries, and T & uuml;rkiye's involvement during the early Republican period offers fresh insight into interwar scientific cooperation. The article documents T & uuml;rkiye's scientific and institutional contributions and analyses them through the reciprocal framework of science impacting diplomacy and diplomacy impacting science. Drawing on archival documents, official correspondence, parliamentary records, and contemporary newspapers, supplemented by expert interviews, it assesses the case against an explicit definition of science diplomacy. T & uuml;rkiye's meteorological data, later incorporated into the synoptic weather maps of the Northern Hemisphere, were scientifically significant, institutionally coordinated, and internationally recognised, yet shaped by asymmetrical hierarchies. The case enriches the historical understanding of science diplomacy by non-hegemonic states.

In this study, the computationally predicted gamma-ray attenuation behavior and fast-neutron removal cross-section characteristics of micrometre-scale CrN, AlCrN, and AlTiCrN ceramic coatings produced via cathodic arc evaporation were investigated. The shielding parameters were not measured by direct gammaor neutron-transmission experiments; instead, mass attenuation coefficients (MAC, mu/rho) in the 0.05-2.50 MeV range were obtained from EGS4 Monte Carlo simulations and Phy-X/PSD calculations, and the agreement between the two computational datasets was evaluated. Energy-dependent attenuation parameters, including half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), radiation protection efficiency (RPE), and kerma coefficients, were calculated. Statistical comparison showed good consistency between EGS4 and Phy-X/PSD for MAC, RPE, HVL, MFP, and kerma coefficients, whereas Zeff exhibited larger method-dependent deviations. All coatings showed higher attenuation at low photon energies due to the photoelectric effect, while Compton scattering dominated at intermediate energies. Among the investigated coatings, CrN exhibited the most favorable calculated gamma-ray attenuation indicators, with lower HVL and MFP values and higher RPE values. The macroscopic fast-neutron removal cross-section (Sigma R) was also calculated as a first-order neutron attenuation indicator, and CrN showed the highest Sigma R value. Considering their limited thickness of approximately 2.3-2.8 mu m, these coatings should not be regarded as replacements for conventional bulk radiation shields. Instead, nitride-based ceramic coatings may serve as secondary or multifunctional surface layers in space-restricted components requiring local radiation attenuation and mechanical durability.

Vergiler mali yönüyle devletler açısından eşsiz bir öneme sahip olmakla birlikte ekonomik, sosyal, kültürel ve diğer türden birtakım amaçlar devletlerin vergi gelirlerinden vazgeçmesi tercihini yaratabilmektedir. Vergi harcaması olarak ifade edilen bu durum; günümüzde ülkelerin vergi politikalarının önemli bir unsuru niteliğindedir. Vergi harcama politikalarının dizaynında ülkelerin ekonomik, sosyal, politik vb. karakteristikleri etkili olmaktadır. Bu araştırmanın amacı Türkiye’de ve seçilmiş bazı ülkelerde (ABD, Almanya, Rusya, Brezilya, Hindistan ve Güney Afrika) vergi harcamalarını uygulama alanları ve belirli istatistikler ışığında incelemektir. Araştırma neticesinde söz konusu ülkelerde ve Türkiye’de vergi harcamalarının birçok ekonomik ve sosyal amaçlara hizmet ettiği görülmüştür. Türkiye’de sosyal amaçlı vergi harcamalarının daha ön planda olduğunu belirtmekle birlikte vergi harcamalarının yöneldiği politika hedefleri ve bu harcamaların yararlanıcıları bakımından dengeli bir görünüm arz ettiğini ifade etmek mümkündür.

Kocağ, Esra Karapınar
This study analyses factors influencing Ukrainian refugees’ migration for work, using household-level data from the UNHCR Survey of Intentions and Perspectives of Refugees from Ukraine. Applying logistic regression and propensity score matching (PSM), it examines key determinants, including gender, age, education, residence status, and planned return duration. Results show men are more likely than women to migrate for work (odds ratio: 2.01), highlighting gender-specific barriers. Older individuals and those with higher education levels exhibit lower migration likelihoods. Refugees in private accommodations are less likely to migrate, suggesting housing stability affects mobility. Longer planned return durations increase work-related migration (odds ratio: 1.25), while travelling with a larger family reduces it. These findings highlight the complexity of refugee labour market integration and the need for policies addressing gender disparities, housing stability, and long-term employment prospects to support refugees’ economic inclusion.

Özdemir, Samed; Yavuzdoğan, Ahmet
This study presents two methods for rapidly and effectively determining the photovoltaic (PV) potential of building roofs in urban areas using aerial photographs and point cloud data. In the first method, the Segment Anything Model (SAM) and Contrastive Language Image Pre-Training (CLIP) models are used to detect roof surfaces and obstacles from aerial photographs. In the second method, the Random Sample Consensus (RANSAC) and Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithms are employed to identify roof surfaces from Light Detection and Ranging (LiDAR) point clouds. Through the first proposed method, the performance of current deep learning approaches in 2.5D PV potential analysis is investigated, while the second approach examines the performance of 3D PV potential analysis compared to the 2D approach. In PV potential analysis, the Photovoltaic Geographical Information System (PVGIS) Application Programming Interface (API) was utilized. The analysis is conducted based on roof parameters obtained through both proposed methods. In building detection, the first approach achieved an Intersection over Union (IoU) score of 94.29%, whereas the second approach attained an IoU score of 91.23%.

Olive leaves are a by-product of olive cultivation and remain underutilized despite their significant potential as a rich source of health-promoting and functional components. Similarly, tarhana, a fermented food product, is known for its valuable nutritional properties. This study aimed to combine these two beneficial products by examining the effect of different concentrations of dried olive leaf powder (0, 2.5, 5, 7.5, and 10% by weight) on the physical, functional, powder, and sensory properties of tarhana samples. Results showed that moisture content of the tarhana samples were below 10% (wet basis, wb). The ash content (2.17-2.71%, wb) and water holding capacity (32.50-59.00%) of samples increased significantly with the addition of olive leaf powder (p<0.05). The pH value of the doughs was found to be around 5.5 and decreased during the fermentation. The wettability and solubility times of all samples were found to be less than 25 seconds and 16 seconds, respectively. All tarhana samples exhibited high flowability and low stickiness properties. Formulations containing up to 7.5% olive leaf powder were well-received by consumers.
