    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, George
    The 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.

    Modernization and gender: a history of girls' technical education in Turkey since 1927
    (Routledge, 2006-10) Toktaş, Şule; Cindoğlu, Dilek
    This 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.

    Anti-imperialism and Kemalism in Turkey's long sixties: Mahir Çayan's theory of revolution in context
    (Brill Academic Publishers, 2021-12) Ülker, Erol
    This 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.

    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, George
    The 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.

    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.

    Integrating vendors into cooperative design practices
    (Taylor & Francis Ltd, 2009) Eskil, Mustafa Taner; Sticklen, Jon
    This paper describes a new approach to cooperative design using distributed, off-the-shelf design components. The ultimate goal is to enable assemblers to rapidly design their products and perform simulations using parts that are offered by a global network of suppliers. The obvious way to realise this goal would be to transfer desired component models to the client computer. However, in order to protect proprietary data, manufacturers are reluctant to share their design models without non-disclosure agreements, which can take in the order of months to put in place. Due to bandwidth limitations, it is also impractical to keep the models at the manufacturer site and do simulations by simple message passing. To deal with these impediments in e-commerce the modular distributed modelling (MDM) methodology is leveraged, which enables transfer of component models while hiding proprietary implementation details. MDM methodology with routine design (RD) methods are augmented to realise a platform (RD-MDM) that enables automatic selection of secured off-the-shelf design components over the Internet, integration of these components in an assembly, running simulations for design testing and publishing the approved product model as a secured MDM agent. This paper demonstrates the capabilities of the RD-MDM platform on a fuel cell-battery hybrid vehicle design example.

    Attachment to god, stressful life events, and changes in psychological distress
    (Springer Heidelberg, 2012-01) Ellison, Christopher G.; Bradshaw, Matt; Küyel, Nilay Behice; Marcum, Jack P.
    Considerable research shows that social relationships, attachments, and support systems promote emotional well-being. The present study adds to this literature by examining the connection between attachments to God and psychological distress. Analyzing longitudinal data (two waves) from a study of Presbyterian (PCUSA) elders and rank-and-file laypersons, results show that: (1) a secure attachment to God at baseline is associated with a decrease in distress over time; (2) a secure attachment to God buffers against the deleterious effects of stressful life events on distress; and (3) an anxious attachment to God exacerbates the harmful effects of stress. In these analyses, a secure attachment to God is a more robust predictor of changes in distress than many, more commonly studied variables including race, gender, SES, and church attendance. Future research should therefore replicate and extend this line of promising scholarship by examining additional outcomes such as psychiatric illness, physical health, and even mortality risk.

    New housing trends in Istanbul
    (Open House Int, 2016-12) Özker, Serpil; Tuğlu Karslı, Hatice Umut
    Externalization that became prominent in 1980s with the globalization brought along dramatic changes in social and spatial areas. The social, cultural and economic events that took place on an international level thanks to globalization made the impact of change felt which was reflected on the urban space and, therefore, on the house, resulting in an increase in the importance of the residential sector. Externalization and developed economic structure enabled more investments into houses which introduced a concept of housing populated in urban fringes starting from the city centers. The housing concept which was shaped by the impacts of the urban transformation after 1980 turned into a new emerging lifestyle in Istanbul in 2000s. Accordingly, the study aims to establish the position of housing in Istanbul and new meanings formed by the socio-cultural changes. In this sense, housing before and after 1980, globalization, gentrification, urban transformation, spatial segregation, socio-economic and cultural aspects were discussed based on the structural benchmarks, and 4 different housing forms, namely the "Loft", "Residence", "Terraced House", and "Gated Communities", with individual structural examples. This study, thus, aims to question the form of tenancy of these houses created through varying concepts and concerns today. The results obtained showed that the housing as an indicator of cultural life in Istanbul has turned into a lifestyle that is shaped by similar aspects and commercial concern, despite different approaches or production forms, eliminating the traces of the cultural life of the society.
