    Notes on the thermal habitat: Thirteen new records for the freshwater algal flora of Turkey
    (National Institute of Science Communication and Policy Research, 2020) Öztürk S.
    Thermal springs are extreme environments for organisms. Cyanobacteria are the group that adapts with success in these environments where there is little diversity of life. In this study, eight different thermal water springs were studied in Kütahya province. Thirteen cyanobacteria taxa were identified as new records for the freshwater algal flora of Turkey. Some morphological and taxonomical characteristics of the taxa were briefly described in this paper, with original photos. © 2020 National Institute of Science Communication and Information Resources (NISCAIR).

    Traditional uses of wild plants in Mardin central district and attached villages (Turkey)
    (National Institute of Science Communication and Policy Research, 2021) Kılıç M.; Yıldız K.; Kılıç F.M.
    This research reveals traditional uses of wild plants found in Artuklu district in Mardin Province in the Southeastern Anatolia Region of Turkey. This study, conducted between 2017 and 2019, gathered information on the medicinal and other uses of plant species traditionally used in Artuklu and the local names of these plants. Face to face surveys were conducted with 183 people in 91 neighbourhoods. The ethnobotanical uses of 125 plants belonging to 35 families, which are traditionally underutilized by the local people, have been recorded. Our results showed that the highest Relative Frequency of Citation (RFC) was recorded for the species Lathyrus pseudocicera Pamp. (0.32). 1 taxon is from Stereocaulaceae of Fungi, 2 taxa are from Pteridophyta and the others 122 taxa are from Magnoliophyta. In the region, plants mostly belonging to the families Fabaceae (21 taxa), Lamiaceae (11 taxa), Asteraceae (10 taxa) and Brassicaceae (10 taxa) were determined. The recorded ethnobotanical uses are for: food (64), medicinal (40), fodder (12), children's toys (5) and various other purposes (4). Due to the fact that Turkish, Kurdish, Arabic and Assyrian people have lived together in the Artuklu district, this ethnic diversity increased the use of wild plants and added richness. Preserving the coexistence of different cultural and religious groups in the research zone is essential for the maintenance of the rich wild plant local heritage. © 2021, National Institute of Science Communication and Policy Research.

    Effect of atmospheric condition on the thermal decomposition kinetics and thermodynamics of lead acetate trihydrate
    (National Institute of Science Communication and Policy Research, 2023) Çilgi G.K.
    In this study thermal decomposition routes and kinetics of lead acetate triydrate are compared in inert (nitrogen) and reactive (oxygen) atmospheres by using thermogravimetric method. The decomposition proceeds with five consecutive stages in the both the atmospheres. The first four stages occur similarly in nitrogen and oxygen atmospheres and the same intermediates are formed. However, the last stage, differs according to the furnace atmosphere. The mixture of PbO and small amount metallic Pb is the final product in nitrogen atmosphere whereas the mixture of PbO and Pb3O4 is the final product in oxygen atmosphere. X-ray powder diffraction method is used in identify of these products. Kinetic calculations of all stages are realized by using Kissinger–Akahira–Sunose (KAS) and Flynn–Wall–Ozawa (FWO) model free methods. These methods are combined with modeling equations to find the effective model and to calculate thermodynamic parameters. It is found that all reactions show good harmony with the nucleation models although their indexes are different. © 2023, National Institute of Science Communication and Policy Research.
