This study aims the real-time monitoring of gases (CO2, N2, O2, H2, H2S, CH4, He, Ar) discharging from natural pools in the Tekke Hamam geothermal field (Denizli) in addition to the geochemical characterization of the field along with the Kizildere geothermal field, both located at the eastern segment of the B&uuml / y&uuml / k Menderes Graben. The continuous gas monitoring experiment (November 2007-October 2008) conducted in the Tekke Hamam geothermal field has revealed temporal variations in the gas compositions, gas flow rate and pool temperature. Different variation components, such as daily variation profiles and peak/Multi-day signals, are detected in the monitored data, which are mainly correlated with shallow and deep processes involving mainly meteorological factors and seismicity induced variations, respectively. Particularly, the coupled variations in the gas compositions and flow rate seem to correlate with seismicity induced permeability modifications within the subsurface during the absence of significant meteorological factors, such as high rainfall and varying atmospheric pressure. The noble gas characterization of the fields have revealed both high 3He/4He and 4He/20Ne isotopic ratios, suggesting a mantle contribution of about 18% for Kizildere and 34% for Tekke Hamam, whereas the other noble gases (Ar, Ne, Kr, Xe) are of atmospheric nature. The different mantle contributions observed in both fields can suggest a different mantle-He flux variably contaminated by crustal helium. The chemical (cation-trace element-anion) and stable isotopic (&amp / #948 / 18O-&amp / #948 / D) contents of the thermal waters reveal high temperature water-rock interaction accompanied by the effects of deep origined gases (mainly CO2 and H2S) discharging from the fields.

DETAILED EVALUATION OF AN EXISTING REINFORCED CONCRETE BUILDING DAMAGED UNDER ITS OWN WEIGHT Bayraktar, Atilla M.Sc., Department of Civil Engineering Supervisor: Prof. Dr. Ahmet Yakut May 2011, 130 pages A significant part of the Turkey&rsquo / s building inventory consists of reinforced concrete frame structures. In addition to that a big part of the existing building inventory in Turkey shows insufficiency in seismic performance damage or failure of structures under their own loads has also been observed. The failure of Z&uuml / mr&uuml / t Apartment building that occurred in 2004 in Konya and resulted in the death of 92 people brings the necessity of researches on robustness and reserve capacities of the buildings under gravity loading to front. In the context of this thesis, the event in Konya that has resulted in the crushing of four columns in Dostlar Building Complex is studied. After the occurrence of the event, the building was visited, plans of existing condition were prepared and pre-assessment was performed. Original plans of the building, strength test results of the concrete samples and reinforcement detection results were obtained. The reasons behind the crushing of the columns have been investigated through a series of analyses based on a number of possible hypotheses. After modeling the building in SAP2000 program, demand-capacity ratios are calculated. Nonlinear behavior of the structure is determined by incremental static pushover analysis and the seismic performance of the building is evaluated by nonlinear procedure described in 2007 Turkish Earthquake Code. To determine the nonlinear behavior under gravity loading and collapse mechanism, incremental vertical pushover analysis is performed.

The geometry, deformation mechanism and kinematics of the S&uuml / rg&uuml / Fault Zone is investigated by using remotely sensed data including Landsat TM and ASTER imagery combined with SRTM, and stereo-aerial photographs. They are used to extract information related to regional lineaments and tectono-morphological characteristics of the SFZ. Various image processing and enhancement techniques including contrast enhancement, PCA, DS and color composites are applied on the imagery and three different approaches including manual, semi automatic and automatic lineament extraction methods are followed. Then the lineaments obtained from ASTER and Landsat imagery using manual and automatic methods are overlaid to produce a final lineaments map. The results have indicated that, the total number and length of the lineaments obtained from automatic is more than other methods while the percentages of overlapping lineaments for the manual method is more than the automatic method which indicate that the lineaments from automatic method does not discriminate man made features which result more lineaments and less overlapping ratio with respect to final map. It is revealed from the detail analysis that, the SFZ displays characteristic deformation patterns of strike-slip faults, such as pressure ridges, linear fault controlled valleys, deflected stream courses, rotated blocks and juxtaposition of stratigraphical horizons in macroscopic scale. In addition to these, kinematic analyses carried out using fault slip data indicated that the S&uuml / rg&uuml / Fault Zone is dextral strike-slip fault zone with a reverse component of slip and cumulative displacement along the fault is more than 2 km.

Spatial analyses of shoreline recession and accretion, and future shoreline position predictions in coastal countries have considerable importance due to engineering, planning, management and environmental concerns. In spite of this importance, there are only a few studies in Turkey. The aim of this thesis are to determine the shoreline rate-of-change of B&uuml / y&uuml / k Menderes Delta, by geographical information systems for the last fifty-year period, in order to approximate future shoreline position of B&uuml / y&uuml / k Menderes Delta shoreline, and to evaluate appropriate models while predicting the future shoreline position. To achieve the purpose of the study time series shoreline position data is extracted from three sets of topographic maps belonging to 1954-1957, 1977-1978 and 1993 aerial photographs and two sets of high resolution satellite imageries (January 2002 Ikonos, August 2004 QuickBird). Then Coastal script of TNTMips, which uses some statistical shoreline analyses methods, that are End Point Rate (EPR), Average of Rates (AOR), Linear Regression (LR) and Jackknifing (JK) is edited so that it can locate the future shoreline positions on the map. Suitable baselines are created and appropriate transect intervals are decided to analyze the shoreline. Finally, some additional analyses that are Backward Analysis and Oscillation Analysis are done to obtain most suitable future shoreline position with rate-of-changes. The results showed that, shorelines having different geomorphologic characteristics needed to be analyzed separately and the linear methods to model the future shoreline position differ from one geomorphologic region to another.

Conservation of industrial heritage is a very popular issue in last years. But this conservation studies are not adequate so a lot of industrial complexes which effected architectural features of industrial buildings, style of producing, production and economic history and social life of citizens, are face to face with being demolished. These complexes should be preserved and inherited to the next generations. One of these complexes is Kayseri Sumerbank Bez Fabrikasi which was established in Early Republican Period in 1934 by Sumerbank in Kayseri. Turkish Government who made merit of development and progress in the first years of republic made a number of investments following variant policies. It was considered that economic independence, social development and modernization could be made by those investments. Industry was one of the major investments. It was aimed to make economy independent by industrialization. Locations for production and materials were decided through a certain plan. The first and the most important of the industrial investments was S&uuml / merbank Bez v Fabrikasi established by S&uuml / merbank in Kayseri. It was not only for economic progress but also for social development. It was built in 1935 by Russian architects in a modernist approach in reinforced concrete system for the first time in Kayseri. Factory was not just a production place. It consisted of a lot of social and service buildings and areas. Kayseri as a city of a longstanding history shaped its future with S&uuml / merbank Bez Fabrikasi. S&uuml / merbank is the basis of the city&amp / #8217 / s industry as it is called an industry center today. S&uuml / merbank Bez Fabrikasi was effective in the development of Kayseri and Turkey with its qualified workers, modernization and progress it brought to city. The main aim of this work is to determine the value of Kayseri S&uuml / merbank Bez Fabrikasi penetrated Turkish Republic&amp / #8217 / s and Kayseri&amp / #8217 / s social and economic development, to state decisions for conservation of those values and to provide reintegration to the city.

This thesis explores popular perception of &#039 / Turkish Cypriotness&#039 / in relation to Greek Cypriots and T&uuml / rkiyeliler in the framework of struggling political discourses proposing conflicting identities to the population in the northern part of Cyprus. Purpose of the study is to understand dominant elements in self-representations of &#039 / native&#039 / Turkish Cypriots in the context of relatively new reality, namely, the partition of the island and immigration from Turkey. In other words, this study focuses on images of &#039 / Turkish Cypriots&#039 / and of their &#039 / Others&#039 / - Greek Cypriots and T&uuml / rkiyeliler- in popular discourse. For the purpose of understanding the self-perception of identity among &#039 / native&#039 / Turkish Cypriots, in-depth interviews were conducted in different cities of the northern part of the island. As a result of analyses of these narratives, the relational and precarious nature of identificatory practice is pointed. Moreover, problems relating to dominant perception of &#039 / Turkish Cypriotness&#039 / marked with hierarchical exclusion of T&uuml / rkiyeliler is stressed. It is concluded that popular perception of &#039 / Turkish Cypriotness&#039 / signals the fact that, more than opening space for a transnational attachment, Cyprus-centered identity fosters exclusivist approach towards T&uuml / rkiyeli &#039 / Other&#039 / .

The main concern of this thesis is examining the affects and causes of traffic oriented design on the social generation of boulevards in terms of communication. For this purpose, boulevard concept and its historical evaluation are explained. In addition, communication is used as a tool for understanding, combining and examining the social and technical structure of boulevard. In this respect, this thesis aims to explore the boulevard concept with the spatial communication measures. To provide empirical evidence, a chart of categories of communication is prepared in terms of human and machine interposed aspects of communication. The activities of relation along the boulevard are examined by transversal and longitudinal movements with the help of the behavioral sciences and proxemics and the theoretical relation between boulevard and communication is applied on the case of The Atat&uuml / rk Boulevard, Ankara. It is observed from the findings that, longitudinal movement prior to situated activity is increased, the transversal movement prior to random activity is decreased. This causes the loss of human aspects along the boulevard, which is designed for human.

The aim of this study is to position T&uuml / rkSolu (TurkishLeft), a weekly newspaper, and its accompanying organizations in Turkey&rsquo / s contemporary socio-political environment. T&uuml / rkSolu, which defines itself as secular/leftist nationalist, will be investigated as a form of reactive nationalism that becomes viable in 2000s. By this means, it will be argued that T&uuml / rkSolu&rsquo / s secular/leftist nationalism is a form of extensively &lsquo / exclusive&rsquo / &ndash / ethnicist &ndash / interpretation of nationalism.

The present study tested the mortality salience (MS) hypothesis of Terror Management Theory (TMT) on attitudes towards allowance of headscarf in the universities. Sample of the current study consisted of 208 university students. Religious, secular and liberal views were evaluated by participants. The results of 2 (Attitude: Supporters, Opponents) X 2 (Condition: Mortality salience, Control) ANOVAs showed that despite the lack of significant main effect of condition and interaction effect, MS tended to lead supporters of headscarf to evaluate both religious and secular essay more favorably but the liberal essay less favorably. On the contrary, opponents of headscarf tended to become supportive of the secular essay but critical of the religious and liberal essay following MS. Findings were discussed considering past literature and alternative theoretical perspectives.

This study is concerned with volcanostratigraphic and petrologic evolution of the S&uuml / phan, which is a 4050 m high Quaternary stratovolcano in eastern Anatolia. The eruptive products of S&uuml / phan Stratovolcano, including transitional mildly alkaline to calc-alkaline rocks, are lavas, domes and pyroclastics ranging in composition from basalts to rhyolites. Ar-Ar age data from different levels of the volcanostratigrafic succession yield a range of 0.76-0.06 Ma. Textural features, wide temperature ranges obtained for intermediate members, and the linear trends of whole-rock geochemistry are strongly suggestive of magma mixing in the evolution of S&uuml / phan volcanics. Presence of crystal clots in many lavas suggests that cogenetic plutonic rocks were also involved in the mixing process. Comparison of whole-rock, melt inclusion and glass chemistry data of S&uuml / phan to data from experimental studies reported in literature indicate that the melt inclusions describe true liquid lines of descent from a common hydrous parent at pressures of ~500 MPa. EC-AFC modeling of trace element and isotopic compositions reveals 2-8% crustal contamination in the differentiated lavas. REE modeling indicates that primitive rocks of S&uuml / phan volcanics were products of mixing of melts from spinel and garnet lherzolite sources, with contributions of 60% and 40%, respectively, in the mixture. A two-stage petrogenetic model is proposed for Suphan stratovolcano. Mantle- derived melts stall and undergo chemical differentiation in a deep hot zone in lower to mid-crust / variably evolved melts ascending from this zone are arrested and mixed at a shallow level where they construct a sub-volcanic magma reservoir beneath Suphan.
