Yayın Thermal quenching of thermoluminescence in quartz samples of various origins(Univ Agean, Dept Mediterranean Stud, 2010) Subedi, Bhagawan; Afouxenidis, Dimitrios; Polymeris, George S.; Bakoglidis, Konstantinos D.; Raptis, Spyridoula; Tsirliganis, Nestor C.; Kitis, GeorgeThe effect of thermal quenching plays an important role in the thermoluminescence (TL) of quartz on which many applications of TL are based. In present work it is investigated that the thermal quenching parameters i.e. the activation energy W and the dimensionless parameter C, are more or less the same for every kind of quartzes or sample dependent on strong external treatment like a high temperature annealing. This preliminary investigation of seven quartz samples of different origin showed that the thermal quenching parameters W and C are common (universal) for most of the quartz samples.Yayın Preliminary TL and OSL investigations of obsidian samples(Univ Agean, Dept Mediterranean Stud, 2010) Polymeris, George S.; Gogou, D.; Afouxenidis, Dimitrios; Rapti, Sofia; Tsirliganis, Nestor C.; Kitis, GeorgeObsidian is a volcaniclastic mineral extremely hard to break, which was used in prehistoric Greece (and elsewhere in the World), in order to provide tools, weapons, knives and arrowheads. The present work aims to characterize this extremely precious tool stone by using both thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques and investigate its potential use for luminescence dating purposes. Basic TL and OSL properties, such as TL and OSL thermal and optical stability, repeatability, TL and LM-OSL glow curve shape and mainly the linearity of the TL and OSL signals as a function of beta dose were investigated. Artificially irradiated samples indicate all promising luminescence features, such as the 110 degrees C TL peak and dose response sub-linearity for intermediate doses, quick and effective bleaching all over the entire TL glow curve, along with quite linear CW-OSL dose response for doses larger than 5 Gy. The lack of predose sensitisation indicates the suitability of the material for single aliquot measurements. Furthermore, several features provide indications that the signal does not relate to quartz, but in fact to other silicates. Unfortunately, both lack of bleaching ability for NIL signal, along with a peculiar shape of NOSL, provide major difficulties in dating applications.Yayın Modernization and gender: a history of girls' technical education in Turkey since 1927(Routledge, 2006-10) Toktaş, Şule; Cindoğlu, DilekThis article is a historical analysis of Girls' Institutes in Turkey. These schools were established in the early Republican era in order to educate girl students to gender roles compatible with modernization and with the westernization project of the Turkish state. The analysis is based upon qualitative data (including interviews and focus groups). The findings point to four trends in the history of Girls' Institutes and in the characteristics and life chances of graduates in the period 1927-70. These were (a) the shift from 'good housewife and mother' training schools to vocational schools; (b) the downgrading of the employment of graduates; (c) a shift from singleness to marriage; and (d) the redefinition of gender roles by women themselves.Yayın TL and OSL response of turquoise for dosimetric application(University of Aegean, 2010) Subedi, Bhagawan; Afouxenidis, Dimitrios; Polymeris, George S.; Tsirliganis, Nestor C.; Paraskevopoulos, Konstantinos M.; Kitis, GeorgeTurquoise is one of the amongst first gem stones used in jewelry and possessing cultural value since 2000 BC (at least). This work attempts characterize this stone scientifically using both thermally (TL) and optically stimulated luminescence (OSL) techniques. The experimental investigation included 1) the study of the natural TL and OSL signals, 2) the reproducibility of TL sensitivity over repeated irradiation and TL readout cycles, 3) dependence of sensitivity on annealing temperatures and 4) the TL and OSL dose response curves. The potential use of the TL and OSL techniques in determination of provenance, accidental dosimetry and probably to authenticity and dating purposes are then discussed.Yayın Anti-imperialism and Kemalism in Turkey's long sixties: Mahir Çayan's theory of revolution in context(Brill Academic Publishers, 2021-12) Ülker, ErolThis article aims to reassess the evolution of Mahir Çayan's theory of uninterrupted revolution in the context of the radical ideological currents of the long sixties in Turkey. It concentrates on Çayan's relations with the National Democratic Revolution (Milli Demokratik Devrim, MDD) movement that enjoyed a considerable degree of political and ideological authority over the youth movements starting in the second half of the 1960s. The article discusses how Çayan interpreted and attempted to revise the theory of national democratic revolution by reference to the changing characteristics of imperialism and colonial domination. Consideration is given to Çayan's critical approach towards the role of Kemalists in the anti-imperialist bloc to be formed.Yayın Space, time, and iconicity in Turkish sign language (TID)(Estonian Academy Publishers, 2012) Arik, EnginMuch evidence points to the conclusion that temporal concepts are drawn primarily from the conceptualization of space. Sign languages provide a particularly suitable area for observing such a relationship since they employ a three-dimensional signing space as a major building block for articulation. This paper addresses spatial and temporal language in Turkish Sign Language (TID), which has a full-fledged grammar and a natural language used by the deaf community in Turkey. It investigates descriptions of static and dynamic spatial situations and expressions of time. Results showed mismatches between the axial information in the stimuli and the use of left-right and front-back axes in the signing space. Furthermore, results also showed that the temporal language did not always correlate with the deictic use of the front-back axis. Thus, these findings suggest that temporal language may only partially be derived from spatial language.Yayın A comparative morphological, compositional and tl study of tenedos (Bozcaada) and Sile aeolianites, Turkey(Univ Agean, 2012) Polymeris, George S.; Erginal, Ahmet Evren; Güneç Kıyak, NafiyeAeolianites are carbonate-cemented deposits of coastal dune sands, mostly of Quaternary age. Even though aeolianite exposures on the coasts of the Mediterranean Sea are frequent, very few records have been documented from the coasts of either the Aegean or the Black Sea. The present study deals with evaluating and comparing both compositions and thermoluminescence (TL) ages of two recently reported samples of coastal aeolianites. Both were recovered at the Turkish coasts of Tenedos (Bozcaada) island, Aegean Sea and Şile, Western Black Sea. In the latter case, being the first record for the specific coastal area, the oldest age obtained was dated at 158±25 ka while the youngest age yielded was 108±14 ka. These values imply that both deposition and cementation occurred during the high sea stand of marine isotope stage 5 (MIS 5). In the case of Tenedos, the aeolianites were deposited between the early stage of the oxygen isotope stage 2 period (OIS 2) and the very late phase of the oxygen isotope stage 3 period (OIS 3). These latter TL results are in excellent agreement with a previous study of the same complex after applying OSL. Besides the ages, a number of luminescent features and properties in conjunction with compositional data suggest the dissimilarity for the quartz samples extracted from the aeolianites recovered at these two sampling sites, excluding thus any transport from one sampling site to the other, despite the short distance of the two sampling sites and the meteorological data regarding the preferable wind directions between them.Yayın The firing temperature of pottery from ancient Mesopotamia, Turkey, using luminescence methods: a case study for different grain-size fractions(Wiley-Blackwell, 2014-10) Polymeris, George S.; Güneç Kıyak, Nafiye; Koul, Dileep K.; Kitis, GeorgeThe assessment of the firing temperature of a prehistoric pottery sample collected from ancient Mesopotamia, Turkey was studied using luminescence techniques. The methods for this estimation involved the observation of the thermal and pre-dose sensitization with various re-firing temperatures for both TL and the OSL signals. In the former case, the 110 degrees C TL peak and the rest of the glow curve were used as proxies in this study. In the framework of a first attempt to investigate the impact of grain-size dependence on the sensitization of the luminescence signals, the aforementioned study was performed with four different pottery grain-size fractions: (i) less than 60m, (ii) 60-90m, (iii) 90-180m and (iv) 180-250m. The results clearly demonstrated the firing temperature mark of approximate to 500 degrees C in for the grain size of 90-180m, whileas in the case of the lower grain-size fractiona third proxy, the ratio of the pre-dosed to the thermal sensitization, was seen to indicate the firing temperature. The remaining two grain-size fractions failed to provide any meaningful results with regard to the firing temperature estimation. The dependence of the TL characteristics on the grain size was explained in the framework of the mixed mineralogy.Yayın New quartz technique for OSL dating of limestones(2010) Liritzis, Ioannis; Drivaliari, N.; Polymeris, George S.; Katagas, Christos G.The equivalent dose De determination of limestone-made ancient constructions by thermoluminescence (TL) prevents accurate measurements and requires plateau test of bleached curves. Optical stimulated luminescence (OSL) of quartz and feldspar minerals for surface dating is routinely applied for De but not for limestones. Here the OSL of present traces of such minerals removed with powder from surface limestone bleached by sunlight overcomes this issue and offers an alternative way for De. This is verified with further test examples.Yayın Threads of Empire: Loyalty and tsarist authority in Bashkiria, 1552-1917(Redaktsiya Zhurnala ab Imperio, 2017) Üre, Pınar[No abstract available]
