    The Galena Objects from Neolithic Ulucak: The Earliest Metallic Finds in Western Turkey
    (Koc Univ Suna & Inan Kirac Res Ctr Mediterranean Civilizations-Akmed, 2020) Cevik, Ozlem; Dirican, Murat; Ulubey, Aydin; Vuruskan, Osman
    The earliest metal finds in central and eastern Anatolia are small copper and malachite beads dating from the 9th millennium BC onwards. However, the presence of metallic finds in Neolithic contexts from western Anatolia are rarely known. An analysis of metallic finds from Ulucak Hoyuk shows that galena was used at the site from the early 7th millennium BC to the early 6th millennium BC. Objects made of galena from initial phases at the site are considered personal ornaments, while an increasing number of galena lumps in relation to ovens were found in later phases. Thus, galena finds from Ulucak Heorik suggest that at first this raw material seemed to have been perceived as an exotic stone, while a full understanding of its properties may have been developed later.

    Meteorological Evaluation of Edirne Air Pollution
    (Amer Inst Physics, 2019) Yilmaz, Merve; Kesaf, Esra; Toros, Huseyin; Ulubey, Aydin; Hristova, Elena
    In this study, how the concentrations of PM10 and SO2 pollutants changed on a seasonally, monthly, weekly and daily basis in Edirne, Turkey was investigated. The concentration values that were measured hourly during January 2012 and June 2018 term and R software was used to analyze and visualize the data. The results show that the concentration of pollutants changes with weather temperature and wind speed. In addition, cold and occasionally snowy winters and hot summers are observed climatologically in Edime. According to the results, both pollutant (PM10, SO2) concentrations increase in winter months and decrease in summer months. Also the pollutant concentration values decrease when the wind speed is equal to or more than 1 m/s in contrast with pollution levels in slower wind speed circumstances.

    PIGMENT IDENTIFICATION IN HELLENISTIC CERAMICS FROM THE TUZ GOLU REGION OF CENTRAL ANATOLIA BY CONFOCAL RAMAN SPECTROSCOPY
    (Inst Chemical Technology, Dept Glass Ceramics, 2008) Ulubey, Aydin; Fazlioglu, Ismail; Erdogu, Burcin
    The chemical nature of the black and red pigments of four samples of Hellenistic ceramics from the Salt Lake (Tuz Golu) region of Central Anatolia has been identified by Confocal Raman Spectroscopy. The black and red pigments are found to be magnetite (Fe3O4) and hematite (alpha-Fe(2)O(3)). Raman spectrum of alumina (Al(2)O(3)) was also taken on white coloured glazes.
