Öğe Türü: Yayın , Recent progress in shape-stable porous polymer foam-based composite phase change materials for efficient thermal energy storage(Elsevier B.V., 2026) El Majd, Abdelkoddouss; Moulakhnif, Kaoutar; Ouadil, Boubaker; Sarı, Ahmet; Döğüşcü, Derya Kahraman; Memon, Shazim Ali; Gençel, Osman; Ali, Nisar; Gençel, Osman; Mühendislik Mimarlık ve Tasarım Fakültesi, İnşaat Mühendisliği BölümüPhase change materials (PCMs) are becoming more common in latent heat thermal energy storage (LHTES) applications and are important to the next generation of ecologically friendly and dependable energy systems. The primary challenges to PCMs practical uses include leakage, inadequate heat transmission, and insufficient stability over time. Polymerized high internal phase emulsion (polyHIPE) is gaining popularity for its ability to create 3D porous structures and store thermal energy, making it ideal for shape-stabilized PCMs (SSPCMs) with improved thermal effectiveness and structural stability for efficient TES applications. This review provides a critical overview of recent advances in PolyHIPE-based SSPCMs for latent heat TES. It presents a comprehensive discussion on PolyHIPE architectures and fabrication strategies, together with a critical analysis of the structure–property relationships governing PCM loading, latent heat storage, leakage resistance, thermal conductivity, and cycling stability. A comparative assessment of thermal performance enhancement strategies, including conductive fillers and functional modifications, is also provided to highlight their effectiveness and limitations. Finally, the review discusses the key challenges facing PolyHIPE-based SSPCMs and proposes a future roadmap toward scalable, multifunctional, and sustainable materials for practical thermal energy storage applications.Öğe Türü: Yayın , Prevalence of fasciolosis and dicrocoeliosis in slaughtered cattle and sheep in Siirt Province, Türkiye: A Comparison of coprological and postmortem findings(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Yasul, Muhammed; Afşar, Milad; Yılmaz, Ali Bilgin; Selçuk, Muhammed Ahmed; Torkamanian-Afshar, Mahsa; Yılmaz, Hasan; Yasul, Muhammed; Bartın Sağlık Hizmetleri Meslek Yüksekokulu, Sağlık Bakım Hizmetleri BölümüThis study aimed to determine the prevalence of the liver trematodes Fasciola spp. and Dicrocoelium dendriticum in cattle and sheep slaughtered in Siirt Province using fecal sedimentation and postmortem liver examination to compare their detection performance, and to estimate the sensitivity of fecal sedimentation relative to postmortem examination. A total of 2211 animals, comprising 374 cattle and 1837 sheep, slaughtered during the study period, were included in the study. Fecal samples were collected rectally before slaughter, and after slaughter, the liver, gallbladder, and bile ducts were examined macroscopically. Fecal samples were analyzed using sedimentation; postmortem examination was the reference method. Based on postmortem examination, Fasciola spp. and D. dendriticum were detected in 26.2% (98/374) and 7.2% (27/374) of cattle, and in 14.8% (271/1837) and 5.9% (108/1837) of sheep, respectively. Fecal examination detected significantly fewer infections for both parasites in both hosts (McNemar test, p < 0.001 for all comparisons). The sensitivity of fecal sedimentation was 80.6% for Fasciola spp. and 29.6% for D. dendriticum in cattle, and 86.7% and 73.1%, respectively, in sheep. The prevalence of Fasciola spp. was significantly higher in cattle than in sheep (OR = 2.05, 95% CI: 1.58–2.67; p < 0.001), whereas the difference in D. dendriticum prevalence between cattle and sheep was not statistically significant (OR = 1.24, 95% CI: 0.80–1.92; p = 0.274). In cattle, age older than two years was significantly associated with Fasciola spp. (adjusted OR = 15.82, 95% CI: 8.12–30.84; p < 0.001) and D. dendriticum infection (adjusted OR = 3.29, 95% CI: 1.36–7.96; p = 0.008). In sheep, the Morkaraman breed had lower odds of Fasciola spp. infection (adjusted OR = 0.42, 95% CI: 0.32–0.56; p < 0.001) and D. dendriticum infection (adjusted OR = 0.23, 95% CI: 0.14–0.38; p < 0.001) than the Akkaraman breed, while age was significantly associated only with D. dendriticum infection (adjusted OR = 1.84, 95% CI: 1.25–2.71; p = 0.002). These findings demonstrate that liver trematode infections were common among slaughtered animals in Siirt. Reliance on fecal sedimentation may considerably underestimate prevalence, particularly for D. dendriticum in cattle. Age- and breed-related associations should be considered in surveillance and control programs. From a public health perspective, awareness of zoonotic fasciolosis and risks associated with consuming raw aquatic plants from potentially contaminated areas should be increased.Öğe Türü: Yayın , Phylogeography of the oriental plane tree uncovers ancient colonization routes across the mediterranean basin(WILEY, 2026) Ashokan, Ajith; Galise, Teresa Rosa; Santangelo, Annalisa; Tunçkol, Bilge; Cozzolino, Salvatore; Fineschi, Silvia; Tunçkol, Bilge; Ulus Meslek Yüksekokulu, Ormancılık BölümüAim: The oriental plane tree is a Tertiary relict species with a fragmented range across southeastern Europe and southwestern Asia, forming a key component of riparian forest vegetation. Despite its ecological and cultural importance, the evolutionary history of this tree species has remained unclear, particularly regarding the relative contributions of ancient and more recent climatic events to its present distribution. Location: Southeastern Europe and Southwestern Asia. Time Period: Cenozoic. Taxon: Platanus orientalis L. (Platanaceae). Methods: We attempted the first plastid genome-based phylogeographic analysis of the species across its native range, coupling phylogenomic evidence with molecular dating to reconstruct its evolutionary history. Results: Mediterranean Anatolia was identified as the primary center of origin and diversification of P. orientalis, with basal Anatolian lineages underpinning an ancient east–west expansion across the Mediterranean Basin. Crete retains a high diversity of deeply divergent haplotypes, consistent with long-term persistence and underscoring the role of large Mediterranean islands as refugia for paleo-endemic lineages. By contrast, southern Italian accessions show reduced plastid diversity and close affinities with West Balkan lineages, indicating more recent colonization. The absence of isolation-by-distance suggests that geographic distance alone does not account for the observed genetic structure in P. orientalis. Main Conclusions: Long-term isolation, insularity, and limited dispersal likely shaped both deep lineage divergence and present-day genetic structure in P. orientalis. This makes the species a survivor of the Tertiary flora and an important biogeographic record of Mediterranean paleogeographic and paleoclimatic history, with clear implications for conserving evolutionarily distinct relict lineages under ongoing climate change.Öğe Türü: Yayın , Mechanical and bonding performance of cross-laminated timber manufactured from heat-treated wood(UNIV BIO-BIO, 2026) Ozan, Zeynep Eda; Onat, Saadettin Murat; Aydemir, Deniz; Onat, Saadettin Murat; Aydemir, Deniz; Orman Fakültesi, Orman Endüstri Mühendisliği BölümüThe chemical and surface changes induced by heat treatment can affect wood-adhesive interactions; however, limited attention has been given to the role of silane-based surface modification in enhancing the bonding and mechanical performance of heat-treated cross-laminated timber (CLT). Heat-treated Pinus sylvestris (Scots pine) and Abies bornmülleriana (Uludağ fir) were used as outer layers in the manufacture of three-layer CLT panels, and their mechanical properties were evaluated in this study. Heat treatment (HT) was carried out at 200 °C for 4 hours according to the Thermo-wood method. Layers were joined using one-component polyurethane-based adhesive. Some samples were treated with a silane-based coupling agent before bonding to improve bonding performance, and the effects of silane on bonding and mechanical properties were studied. Within this frame, tensile shear strength (TSS), bending shear strength (BSS), modulus of elasticity in bending (MOE), and tensile strength perpendicular to the surface (PTS) were measured. According to the results, silane modification generally improved mechanical performance, leading to a significant 74 % increase in PTS in Scots pine, while also affecting BSS (13 %) and MOE (7 %) in fir. In contrast, HT mainly altered bending-related behavior, most notably in Uludağ fir (BSS ≈ 10 %). Uludağ fir samples showed a higher BSS performance when compared to Scots pine ones. Overall, this study emphasizes that HT and silane modification can improve the mechanical performance of CLT, with effects varying by wood species and mechanical properties, providing valuable insights for the enhancement of low-durability wood.Öğe Türü: Yayın , Measures of noncompactness to solve a new fractional differential equation of higher order on unbounded domain in the new banach space(Springer India, 2026) Kayvanloo, Hojjatollah Amiri; Khanehgir, Mahnaz; Mursaleen, Mohammad; Mursaleen, Mohammad; Fen Fakültesi, Matematik BölümüIn this paper, we introduce a new Banach space equipped with a weighted norm depending on a function, and we characterize the compact subsets of this space. Based on this characterization, we define a new measure of noncompactness adapted to this functional framework. Using this measure of noncompactness together with Darbo’s fixed point theorem, we study the solvability of a higher-order Caputo fractional differential equation on an unbounded domain with nonlocal boundary conditions. The main novelties of this work are the introduction of the weighted Banach space, which is particularly suitable for problems on unbounded domains; the construction of a new measure of noncompactness that captures both the lack of equicontinuity and the lack of uniform decay at infinity; and the analysis of a new class of higher-order fractional boundary value problems. Finally, we provide a concrete example to illustrate the applicability of our main result.
