    A Survey On the Visibility Of Mosaic Heritage On The UNESCO World Heritage List
    (Bursa Uludağ University, 2025) Akture, Z.
    World Heritage Programme was launched under the auspices of UNESCO by adopting the Convention concerning the Protection of the World Cultural and Natural Heritage in 1972. 1223 cultural, natural, and mixed properties have been inscribed on the World Heritage List (WHL) from 1978 to 2024 to ensure international consideration and assistance in their preservation as patrimony of humanity. This paper offers an insight into the visibility of mosaic heritage in this corpus through a survey of references to mosaics in the Statements of Outstanding Universal Value (OUV) on the homepages of World Heritage properties at UNESCO’s website. After an introduction on the requirements for inscription on WHL, distribution of mosaics in World Heritage properties is surveyed in reference to their category, location on the globe, and setting within the property to highlight over- and under-representations, with inspiration from the current strategy of achieving a balanced representation of heritage types, chronologies-regions, and themes on WHL. Then selected “exceptions” in terms of mosaic types, locations, and periods are presented to contribute in increasing their visibility, followed by “highlights” in whose Statements of OUV the word “mosaic” is most repeated. Adopting the wholistic approach recommended in the World Heritage Programme, both sections aim to contextualise the selected examples in the overall corpus and mosaic heritage as an element forming and representing their attributes of OUV. After observing the thus exemplified variety in the mosaic heritage so far inscribed on WHL, concluding remarks highlight areas of further research to deepen the presented visibility analysis. © (2024), ().

    Design of Sulfur Resistant Cobalt Catalysts by Boron Promotion: Atomic Scale Insights
    (Sakarya University, 2024) Kizilkaya, A.C.
    The effect of boron promotion on atomic sulfur formation by hydrogen sulfide dissociation on Co(111), flat surfaces of cobalt nanoparticles, was investigated using Density Functional Theory calculations. The results show that on clean Co(111), hydrogen sulfide dissociation proceeds fast due to low activation barriers, yielding atomic sulfur on the cobalt surfaces. Boron promotion hinders the dissociation of hydrogen sulfide due to increased activation barriers. Furthermore, boron prevents the interaction of sulfur compounds with cobalt surface atoms, as these poisons bind on boron. The findings indicate that boron is an effective promoter that can be used to design sulfur resistant cobalt catalysts. © 2024, Sakarya University. All rights reserved.

    Occurrence of Bromide and Bromate in Chlorinated Indoor Swimming Pools, And Associated Health Risks
    (Yildiz Technical University, 2023) Dumanoğlu, Y.; Genisoglu, M.; Sofuoglu, S.C.
    Swimming is a physical activity that is accessible to people of all ages in all seasons. However, continuous organic and inorganic precursor load and disinfectant dosing make pool water chemistry much more complex than other disinfected waters. Carcinogenic bromate compound is one of the hundreds of disinfection by-products in pool water. The occurrence of bromate in pool waters depends on the precursor content of filling water, the disinfection process, operating parameters, and the purity of disinfectants. While the average filling water bromide concentrations of University Campus indoor swimming pool in Gülbahçe –Urla (SP1) and Buca public indoor swimming pool (SP2) were determined to be 182 μg/L and 11.0 μg/L, respectively, the average bromate concentrations of SP1 and SP2 were 59.4 μg/L and 68.3 μg/L. Estimated chronic-toxic health risks of accidental ingestion of pool water during swimming (between 10-3 and 10-1) were lower than the threshold level (‘1’). Although the carcinogenic risks in central tendency scenario (<10-6) indicate negligible risks for swimmers, worst case scenario indicates carcinogenic risks (medians were ranged from 1.61×10-6 to 9.42×10-6) for highly exposed specific swimmer groups. Bromate accumulation in swimming pools needs attention for mitigating the health risks for swimmers. © 2021, Yıldız Technical University.

    Investigation of Interactions of Acetylene Molecules With an Iron Nanowire and Its Effects on Mechanical Tensile Properties
    (Sakarya University, 2021) Aral, G.
    Understanding complex atomistic-scales interactions mechanisms of reactive acetylene (C2H2) molecules with reactive pure iron nanowires (Fe NWs) including its effects on the tensile mechanical properties of NWs is a crucial task in nanotechnology, especially having practical significance in the mechanical reliability, durability and stability. Therefore, we performed molecular dynamics (MD) simulations based on ReaxFF reactive force field interatomic potential model to investigate the interactions of C2H2 molecules with surface of cylindrical pure Fe NW and its fundamental effects on the tensile mechanical deformations properties of NWs at three different strain rates. Our results reveal that the chemical energetic reactions on the free surface of cylindrical Fe NW with C2H2 molecules in the gas phase form FexCyHz shell layer at temperature T=300 K. The presence of FexCyHz shell layer on the free surface of NW has a significant effect on the mechanical tensile deformation mechanism of the NWs. © 2021, Sakarya University. All rights reserved.

    Identification of Cytoplasmic Sialidase Neu2-Associated Proteins by Lc-ms/Ms
    (Türk Biyokimya Derneği, 2019) Akyıldız Demir, Seçil; Seyrantepe, Volkan
    Background: Cytoplasmic sialidase (NEU2) plays an active role in removing sialic acids from oligosaccharides, gly-copeptides, and gangliosides in mammalian cells. NEU2 is involved in various cellular events, including cancer metabolism, neuronal and myoblast differentiation, proliferation, and hypertrophy. However, NEU2-interacting protein(s) within the cell have not been identified yet. Objective: The aim of this study is to investigate NEU2 interacting proteins using two-step affinity purification (TAP) strategy combined with mass spectrometry analysis. Methods: In this study, NEU2 gene was cloned into the pCTAP expression vector and transiently transfected to COS-7 cells by using PEI. The most efficient expression time of NEU2- tag protein was determined by real-time PCR and Western blot analysis. NEU2-interacting protein(s) were investigated by using TAP strategy combined with two different mass spectrometry experiment; LC-MS/MS and MALDI TOF/TOF. Results: Here, mass spectrometry analysis showed four proteins; a-actin, beta-actin, calmodulin and histone H1.2 proteins are associated with NEU2. The interactions between NEU2 and actin filaments were verified by Western blot analysis and immunofluorescence analysis. Conclusions: Our study suggests that association of NEU2 with actin filaments and other protein(s) could be important for understanding the biological role of NEU2 in mammalian cells.
