Öğe Türü: Yayın , Plant family identity drives arbuscular mycorrhizal fungal spore abundance and community structure in natural rangelands(Springer Science and Business Media Deutschland GmbH, 2026) Palta, Şahin; Baş, Eren; Yavaşcı, Zekeriya; Palta, Şahin; Baş, Eren; Orman Fakültesi, Orman Mühendisliği BölümüArbuscular mycorrhizal fungi (AMF) are important components of belowground biotic networks, yet variation in AMF spore abundance and community structure among plant families in natural rangelands remains insufficiently understood. This study investigated AMF spore abundance, community composition, and rhizosphere soil properties across five plant families in a natural rangeland in northwestern Türkiye. Variation in soil organic carbon, total nitrogen, available potassium, CaCO₃ content, and AMF spore density was observed among the sampled plant groups. AMF spore density was highest in Asteraceae (609.8 spores 50 g⁻1 soil) and lowest in Urticaceae (77.6 spores 50 g⁻1 soil). Pearson correlation analysis showed a positive association between AMF spore density and soil pH (r = 0.47) and negative associations with electrical conductivity (EC; r = − 0.49), available potassium (K; r = − 0.44), and total nitrogen (N; r = − 0.40). Acaulospora tuberculata, Claroideoglomus etunicatum, Funneliformis geosporum, Glomus sp., and Rhizophagus clarus occurred in the rhizosphere soils of all five plant families, indicating broad distribution across the investigated host groups. Species richness was highest in Urticaceae, whereas Shannon diversity and evenness were highest in Lamiaceae; Fabaceae and Asteraceae showed lower diversity values. Jaccard similarity was highest between Fabaceae and Asteraceae. Overall, AMF spore abundance and community patterns varied among the sampled plant groups and were associated with rhizosphere soil conditions in the investigated rangeland.Öğe Türü: Yayın , Physiological and anthropometric characteristics of Croatian national football team players(Asociacion Espanola de Analisis del Rendimiento Deportivo, 2026) Dilek, Ahmet Naci; Jalali, Parham; Mohammadi, Aida; Nobari, Hadi; Preljević, Adem; Bazanov, Boriss; Grle, Ivana; Grle, Maki; Šabić, Ernest; Ćeleš, Naim; Skender, Nijaz; Sporiš, Goran; Prlić, Jerko; Tiric, Dejan; Galic Tiric, Bozenka; Kurtović, Natalija; Antonić, Davorin; Čular, Dražen; Franjko, Ivica; Duroci, Ivan; Ljesević, Davor; Ajman, Hrvoje; Širić, Željko; Fiorentini, Fredi; Kovacevic, Zeljko; Morina, Besnik; Milošević, Milan; Vukicevic, Veljko; Dilek, Ahmet Naci; Spor Bilimleri Fakültesi, Rekreasyon BölümüThe aim of this study was to analyse physiological and anthropometric characteristics of Croatian national football team players, with particular focus on blood lactate concentration, relative oxygen consumption, body height, body mass, body fat percentage, and playing position. The sample consisted of 17 elite football players. Descriptive statistical analysis was performed for all analysed variables. The average blood lactate concentration was 10.46 ± 1.12 mmol/L, while the average relative oxygen consumption was 60.91 ± 3.15 mL/kg/min. The players demonstrated highly developed aerobic and anaerobic capacities characteristic of elite football populations. Anthropometric and physiological profiles differed according to playing position, reflecting specific tactical and physical demands in modern football.Öğe Türü: Yayın , NOVEL INSIGHTS ON λ-STATISTICALLY CONVERGENT SEQUENCES IN NEUTROSOPHIC n-NORMED LINEAR SPACES(Kangwon Kyungki Mathematical Society, 2026) Hossain, Nesar; Granados, Carlos; Kişi, Ömer; Kişi, Ömer; Fen Fakültesi, Matematik BölümüIn this research paper, we introduce a thorough exploration of λ-statisticaconvergence and develop some of its interesting properties in neutrosophic n-normed linear spaces. Also, we define the notion of λ-statistical Cauchy sequence and prove that every neutrosophic n-normed linear space is λ-statistically complete. Further-more, we study the concept of [V, λ]-summability associated with λ-statistical convergence with regard to neutrosophic n-norm. And we obtain the relation between statistical convergence and λ-statistical convergence within this specific framework.Öğe Türü: Yayın , Notational analysis of the Croatian first football league: Technical, tactical and performance indicators during the 2025/2026 season(Asociacion Espanola de Analisis del Rendimiento Deportivo, 2026) Dilek, Ahmet Naci; Preljević, Adem; Bazanov, Boriss; Grle, Ivana; Grle, Maki; Šabić, Ernest; Ćeleš, Naim; Skender, Nijaz; Sporiš, Goran; Prlić, Jerko; Tiric, Dejan; Tiric, Bozenka Galic; Kurtović, Natalija; Antonić, Davorin; Čular, Dražen; Franjko, Ivica; Duroci, Ivan; Ljesević, Davor; Ajman, Hrvoje; Širić, Željko; Fiorentini, Fredi; Kovacevic, Zeljko; Morina, Besnik; Milošević, Milan; Vukicevic, Veljko; Dilek, Ahmet Naci; Spor Bilimleri Fakültesi, Rekreasyon BölümüThe aim of this study was to analyse technical and tactical performance indicators in the Croatian First Football League (SuperSport HNL) during the 2025/2026 competitive season. Match analysis has become an essential tool in modern football, allowing coaches, analysts, and researchers to identify performance patterns associated with successful outcomes. This study evaluated offensive and defensive parameters, possession-based indicators, passing efficiency, shots on target, expected goals (xG), pressing intensity, and situational variables related to match outcome. Data were collected from official league statistics and video analysis platforms across all league matches during the observed season. Variables included total passes, successful passes, possession percentage, shots, shots on target, expected goals, duels won, high-intensity pressing actions, recoveries in the final third, and set-piece efficiency. Descriptive statistics and inferential analyses were applied to determine differences between winning, drawing, and losing teams. The results demonstrated that winning teams achieved significantly greater passing accuracy, higher xG values, more successful high pressing sequences, and increased efficiency in transition phases. Teams positioned in the upper part of the league table also showed greater tactical compactness and offensive organization compared to lower-ranked teams. Furthermore, home teams demonstrated statistically significant advantages in ball possession and attacking efficiency. The findings contribute to the growing body of literature regarding notational analysis in elite football and provide practical implications for coaches, analysts, and performance specialists working within Croatian and European football environments.Öğe Türü: Yayın , Lignin as a renewable carbon platform for electrochemical energy storage: structural insights, conversion pathways, and performance perspectives(Springer Verlag, 2026) Kalkan, Elanur; Gülsoy, Sezgin Koray; Kalkan, Elanur; Gülsoy, Sezgin KorayThe rapid growth in global energy demand has increased the need for sustainable energy storage technologies. Electrochemical devices such as batteries and supercapacitors play an important role in modern energy storage systems. However, electrode materials, the main component of these devices, are often associated with high costs, limited supply, and geopolitical risks. In this context, lignin, an abundant and renewable plant-derived biopolymer, has attracted growing interest as a potential electrode material owing to its high carbon content, aromatic structure, and diverse functional groups. This review summarizes recent advances in the use of lignin as a carbon precursor and functional additive for electrochemical energy storage. It covers lignin chemistry, biomass-dependent structural diversity, isolation technologies, chemical modification strategies, and their applications in supercapacitors, lithium-ion batteries, and sodium-ion batteries. Beyond providing a descriptive overview, the review critically examines lignin-derived energy-storage materials through a continuous structure-process-property-performance framework. Particular attention is given to how biomass origin and lignin isolation chemistry determine molecular characteristics, including monomer composition, interunit linkage distribution, molecular condensation, and functional-group chemistry. These precursor characteristics are subsequently linked to carbonization and activation behavior, pore development, graphitic ordering, heteroatom retention, and surface chemistry. The resulting physicochemical properties are then correlated with ion transport, electrical conductivity, charge-storage mechanisms, electrochemical performance, and device-level relevance in supercapacitors, lithium-ion batteries, and sodium-ion batteries. By integrating these interconnected stages, this review provides mechanistic design principles for the rational development of sustainable lignin-derived electrode materials for next-generation energy storage technologies.
