    We investigated the phylogenetic relationships of Pseudophoxinus (Cyprinidae: Leuciscinae) species from central Anatolia, Turkey to test the hypothesis of geographic speciation driven by early Pliocene orogenic events. We analyzed 1141 aligned base pairs of the complete cytochrome b mitochondrial gene. Phylogenetic relationships reconstructed by maximum likelihood, Bayesian likelihood, and maximum parsimony methods are identical, and generally well supported. Species and clades are restricted to geologically well-defined units, and are deeply divergent from each other. The basal diversification of central Anatolian Pseudophoxinus is estimated to have occurred approximately 15 million years ago. Our results are in agreement with a previous study of the Anatolian fish genus Aphanius that also shows a diversification pattern driven by the Pliocene orogenic events. The distribution of clades of Aphanius and Pseudophoxinus overlap, and areas of distribution comprise the same geological units. The geological history of Anatolia is likely to have had a major impact on the diversification history of many taxa occupying central Anatolia; many of these taxa are likely to be still unrecognized as distinct.

    Plant available-phosphorus (P) is usually low in Anatolian soils due mainly to the precipitation as calcium (Ca) and magnesium (Mg) phosphates in alkaline conditions. Phosphate solubilizing microorganisms (PSM) can enhance plant P-availability by dissolving the hardly soluble-P within the rhizosphere, which is the zone that surrounds the plant roots. PSM's can be used as seed- or soil-inocula to increase plant P-uptake and the overall growth. A total of 162 PSM's were isolated from the rhizosphere of wheat plants excavated from different fields located along a 75 km part of a highway in Turkey. The mean, the standart deviation, and the median for solubilized-P (ppm) in a 24 h culture in a tricalcium phosphate broth were 681, 427, and 400 for glucose; 358, 266, and 236 for sucrose; and 102, 117, and 50 for starch, respectively. There was not a linear relationship between the phosphate solubilized in the liquid cultures and the solubilization index obtained in the Pikovskaya's agar. Nine isolates representing both weak and strong solubilizers [Bacillus megaterium (5), Bacillus pumilis (1), Pseudomonas syringae pv. phaseolica (1), Pseudomonas fluorescens (1), Arthrobacter aurescens (1) as determined by the 16S rRNA gene sequence analysis] were further studied in a five day incubation. Pseudomonas syringae pv. phaseolica solubilized statistically (P<0.05) higher phosphate (409 ppm) than all the other strains did. There was not a statistically significant (P<0.05) difference in solubilized-P among the Bacillus strains. The pH of the medium fell to the levels between 4 and 5 from the initial neutrality. The phosphate solubilizing strains variably produced gluconic, 2-keto-D-gluconic, glycolic, acetic and butyric acids. The organic acids produced by these microorganisms seem to be the major source of phosphate solubilization in vitro.

    The Anatolian plate (Turkey) was formed during the late Miocene-Pliocene transition from contractional strain in central and eastern Anatolia (collision) to localized strike-slip faulting along inherited collisional structures (escape tectonics). Structural inheritance undoubtedly played a role in this major plate boundary reorganization, although its significance is not well understood. Considerable uncertainty also exists regarding the timing and kinematics of Tauride-Eurasia collision, initial Arabia-Eurasia collision, and the terminal closure of the Neotethys Ocean. The Sivas Basin is a ~E-W-elongate collisional forearc basin located between the Tauride micro-continent in the south and the Pontide Arc along the southern Eurasian margin in the north. Well-exposed contractional structures in Paleocene-Eocene marine strata of the Southern Sivas fold and thrust belt (SSFTB) provide an excellent opportunity to investigate the timing and kinematics of both Tauride and Arabian collisions and their potential roles in localizing strain and facilitating tectonic escape. We use detailed geologic mapping, structural analysis and detrital geo/thermochronology to investigate the magnitude, style, and timing of collision-related crustal shortening across the SSFTB. The structural geology of the SSFTB is characterized by ENE- to ESE-trending, gently plunging fault propagation folds with slight asymmetry towards the north. Vergence on thrust faults is mainly towards the north, although a few previously unmapped faults are south-vergent. Detrital apatite fission track data from Paleocene-Eocene strata reveal a single phase of rapid exhumation ca. ~36-31 Ma, which may be related to either Tauride or initial Arabian collision. We propose that structural growth of the SSFTB at this time played a major role in marine basin isolation and early Oligocene evaporite deposition. In the central and northern Sivas Basin where salt was likely thickest, salt tectonics was initiated by

    Full Text Available A mural excavated at the Neolithic Çatalhöyük site (Central Anatolia, Turkey has been interpreted as the oldest known map. Dating to ∼6600 BCE, it putatively depicts an explosive summit eruption of the Hasan Dağı twin-peaks volcano located ∼130 km northeast of Çatalhöyük, and a birds-eye view of a town plan in the foreground. This interpretation, however, has remained controversial not least because independent evidence for a contemporaneous explosive volcanic eruption of Hasan Dağı has been lacking. Here, we document the presence of andesitic pumice veneer on the summit of Hasan Dağı, which we dated using (U-Th/He zircon geochronology. The (U-Th/He zircon eruption age of 8.97±0.64 ka (or 6960±640 BCE; uncertainties 2σ overlaps closely with (14C ages for cultural strata at Çatalhöyük, including level VII containing the "map" mural. A second pumice sample from a surficial deposit near the base of Hasan Dağı records an older explosive eruption at 28.9±1.5 ka. U-Th zircon crystallization ages in both samples range from near-eruption to secular equilibrium (>380 ka. Collectively, our results reveal protracted intrusive activity at Hasan Dağı punctuated by explosive venting, and provide the first radiometric ages for a Holocene explosive eruption which was most likely witnessed by humans in the area. Geologic and geochronologic lines of evidence thus support previous interpretations that residents of Çatalhöyük artistically represented an explosive eruption of Hasan Dağı volcano. The magmatic longevity recorded by quasi-continuous zircon crystallization coupled with new evidence for late-Pleistocene and Holocene explosive eruptions implicates Hasan Dağı as a potential volcanic hazard.

    In this study, the lignite-bearing Yoncali formation between Yozgat and Sorgun, in central Anatolia has been palynologically examined. Based on 37 outcrop samples, quantitative palynological studies recognized 64 genera and 136 palynoflora species in the palynological assemblage, which indicated a Middle-Late Eocene age. This paper also presents a quantitative palaeovegetation and palaeoclimate reconstruction for the Middle-Upper Eocene coal occurrences of Central Anatolia on the basis of palynomorph assemblages. The diversified floral and ecological characteristics of the pollen taxa indicates that the Middle-Upper Eocene formations in central Anatolia were characterized by the presence of a complex mangrove swamp with contributions by Nypa, Pelliciera, Avicennia, Diporites tszkaszentgydrgyi and dinoflagellate cysts which reflect warm climatic conditions. Lowland-riparian and montane elements are characterized by the dominance of Myricaceae, Symplocaceae, Icacinaceae, Quercus, Pinus and Castanea. Swamp-freshwater elements are represented by Sparganjaceae, Nymphaceae, Taxodjaceae, Cupressaceae and Nyssa as well as fern spores such as Osmundaceae and Gleicheniaceae. The calculations were performed with the help of the 'Coexistence Approach' method to climatically evaluate palynoflora from the Yozgat-Sorgun area. The obtained results have been compared to data derived from the application of the Coexistence Approach to other, already published Central Anatolian palynofloras of the same age. The results of the climatic inferences suggest that the palaeoclimatic conditions were in the megathermal zone, megatherm/mesotherm intermediate zone whereas mesothermic conditions prevailed in the montane region. Likewise, the results of mean annual range of temperatures indicate the influence of the Indian ocean, which enabled the development of the mangroves.

    As a part of the CyprusArc project, a seismic wide-angle reflection/refraction profiles were carried out in March 2010. The 300 km and 45 km long north-south trending profiles extended from Cihanbeyli in Central Anatolia to Anamur in eastern Mediterranean, Turkey and in southern Cyprus, respectively. The purpose of the project is to observe the impact of the transition from subduction to continent-continent collision of the African plate with the Anatolian plate. The field experiment comprised two land shots (1125 kg explosives) in Turkey and airguns (98 cubic liters) on the Mediterranean sea, beneath Cyprus. 244 stations were installed on land for data acquisition. 77 three-component sensors and 167 vertical-component sensors were installed along ~300 km distances between Cihanbeyli and Anamur with an average spacing of 1.25 km, on Turkey. 24 three-component sensors and 21 vertical component sensors were deployed along 45 km distances on land at southern Cyprus with an average spacing of 1.25 km. To reveal a good data quality, a visual quality check, frequency analysis and filtering were applied to the seismic data. Two land shots on Turkey (also recorded on Cyprus) and airgun shots on the Mediterranean sea beneath Cyprus, geological and previous seismic investigations provide information to derive a layered velocity models beneath from the Anatolian plateau to eastern Mediterranean, Turkey and for the ophiolite complex on Cyprus. After picking observed seismic phases, finite-differences ray tracing of the wide-angle data leads a 2-D crustal P-wave velocity models. The results show moho depth increases from 38 km to 45 km depth along north-south trending profile on Turkey and crustal thinning between south Turkey and Cyprus from 40 km to 36 km. Obtained models were further refined using forward modeling to generate synthetic seismograms for individual shot gathers. Thus, by varying the velocity structure, the theoretical times and amplitudes of the various

    This work focuses on the relationship between the coal deposition and explosive volcanism of the Miocene basin, NW central Anatolia, Turkey. The coal-bearing Hirka Formation was deposited over the Galatian Andesitic Complex and/or massive lagoonal environments during the Miocene. The investigated lignite is a high ash (from 32 to 58%) and sulphur (from 1.43 to 3.03%) lignite which is petrographically characterised by a high humunite content. The mineral matter of the studied lignite samples is made up of mainly clay minerals (illite-smectite and kaolinite), plagioclase and quartz in Bolu coal field, clay minerals (illite-smectite, smectite and illite), quartz, calcite, plagioclase and gypsum in Seben coal field, quartz, K-feldspar, plagioclase and clay minerals (kaolinite and illite) in Kibriscik, and dolomite, quartz, clinoptilolite, opal CT and gypsum in Camhdere coal field. The differences in these four types of lignite with specific mineralogical patterns may be due to the explosive volcanic events and depositional conditions which changed from one coal field to the others. There is a zonation from SW to SE in the studied area for zeolites. Carbonate minerals are commonly calcite in Seben and Kibriscik coal fields. In Bolu, coal samples are devoid of calcite and dolomite. These analyses show that there is an increase in the amount of Mg and a decrease in the amount of Na from the northwestern part to the southern part in the study area.

Analyses of heavy mineral fraction show presence of metamorphic and igneous minerals which indicate participation of weathering products from other rock types in the nearby area. The types of heavy minerals in soils depend more on composition of parent rocks and geomorphic position than on climate type. Soils from Nova Lovcha show similar composition, but the quantity of goethite and hematite significantly increase in soil from plain. Typical high-metamorphic minerals as andalusite, kyanite and sillimanite present only in Nova Lovcha, while garnet dominates in Petrovo and opaque minerals - in Dobrostan. Red soils, formed on slopes, where erosion prevails over accumulation, contain more illite, smectite and vermiculite-smectite, and very few or no kaolinite, whereas the kaolinite is dominant in soils formed on plain.

    Pyroclastic rocks used in both historical and modern structures are inevitably exposed to various weathering processes, leading to damage and destruction of them. To reduce the effects of weathering caused by various atmospheric effects, geologists need to know what processes are more effective and how they affect rock bodies. In this study, our aim is to show the relationship between the weathering and welding degree of pyroclastic rocks, sampled around the Ancient City of Kilistra in Konya (Central Anatolia, Turkey). For this purpose, we conducted field trips, and used petrographic and laboratory techniques such as, physico-mechanical tests and accelerated weathering tests (i.e., Freeze-Thaw, F-T; Wetting-Drying, W-D and Salt Crystallization, SC). Pyroclastic rocks around Kilistra ancient city comprise two different sub-units: the unwelded, lower pyroclastic unit (LPU) and the welded, upper pyroclastic unit (UPU). Following cycles of F-T and SC tests, we observed an increase in porosity values, but a decrease in uniaxial compressive strength values, which was more evident in unwelded-LPU samples. Also, the significant macroscopic textural changes occurred in LPU samples, linked to their unwelded nature. However, physico-mechanical features of both LPU and UPU samples were not significantly changed after W-D tests. Altogether, our findings show that welding degree is one of the main factors controlling weathering and physico-mechanical properties of pyroclastic rocks, and also F-T and SC are more effective processes than W-D on weathering. Accordingly, our approach here could be used to protect the endangered historical structures carved into pyroclastic rocks around the world.

    We present here a reappraisal of the tectonic setting, stratigraphy and palaeogeography of the central part of the Sivas Basin from Palaeocene to late Miocene. The Sivas Basin is located in the collision zone between the Pontides (southern Eurasia) and Anatolia (a continental block rifted from Gondwana). The basin overlies ophiolites that were obducted onto Anatolia from Tethys to the north. The Central Anatolian Crystalline Complex (CACC) experienced similar ophiolite obduction during Campanian time, followed by exhumation and thrusting onto previously emplaced units during Maastrichtian time. To the east, crustal extension related to exhumation of the CACC created grabens during the early Tertiary, including the Sivas Basin. The Sivas Basin underwent several tectonic events during Paleogene-Neogene. The basin fill varies, with several sub-basins, each being characterised by a distinctive sequence, especially during Oligocene and Miocene. Evaporite deposition in the central part of the basin during early Oligocene was followed by mid-late Oligocene fluvio-lacustrine deposition. The weight of overlying fluvial sediments triggered salt tectonics and salt diapir formation. Lacustrine layers that are interbedded within the fluviatile sediments have locally yielded charophytes of late Oligocene age. Emergent areas including the pre-existing Sivas Basin and neighbouring areas were then flooded from the east by a shallow sea, giving rise to a range of open-marine sub-basins, coralgal reef barriers and subsiding, restricted-marine sub-basins. Utilising new data from foraminifera, molluscs, corals and nannoplankton, the age of the marine transgression is reassessed as Aquitanian. Specifically, age-diagnostic nannoplankton assemblages of classical type occur at the base of the transgressive sequence. However, classical stratigraphic markers have not been found within the planktic foraminiferal assemblages, even in the open-marine settings. In the restricted-marine sediments

Pyroclastic flow deposits (i.e. ignimbrites with rhyolitic to dacitic compositions) and low-viscosity sub-alkaline/alkaline basaltic lava fields are widely exposed in the study area. Geomorphology of the region is controlled by strike-slip faults related to the neotectonics of Central Anatolia and the erosion/deposition of the Kızılırmak River. Quaternary terraces which are composed of coarse-grained thick sedimentary beds are the products of the Kızılırmak River. In this study, we will present the preliminary results of our new studies in the northwest of the Gülşehir area, specifically aiming to reveal the geology, petrology and tectonic evolution of this part of Central Anatolia.

    Yıldızeli region to the south of İzmir Ankara Erzincan suture zone is situated on the large Sivas Tertiary sedimentary basin. After the northern branch of the Neotethyan Ocean was northerly consumed beneath the Sakarya Continent, a continent - continent collision occurred between the Anatolide- Tauride platform and Pontides and followed a severe intermediate magmatism during the Late Cretaceous- Tertiary period. This created an east-west trending volcanic belt along the whole Pontide range. In the previous studies different models are suggested for the Eocene volcanic succession such as post-collisional, delamination and slab-breakoff models as well as the arc model for its westernmost parts. We will present our field and geochemical data obtained from the Yıldızeli and its surroundings for its petrogenesis, and will discuss the tectonic model(s) on the basis of their geochemical/petrological aspects. Cenozoic volcanic sequences of Yıldızeli region which is the main subject of this study, overlie Pre-Mesozoic crustal meta-sedimentary group of Kırşehir Massif, Ophiolitic mélange and Cretaceous- Paleocene? flysch-like sequences. In the northern part of Yıldızeli region, north vergent thrust fault trending E-W seperates the ophiolitic mélange complex from the Upper Cretaceous-Paleocene and Tertiary formations. Volcano-sedimentary units, Eocene in age, of the Yıldızeli (Sivas-Turkey) which are intercalated with sedimentary deposits related to the collision of Anatolide-Tauride and a simultaneous volcanic activity (i.e. the Yıldızeli volcanics), exposed throughout a wide zone along E-W orientation. Yıldızeli volcanics consist of basalts, basaltic-andesites and andesitic lavas intercalated flow breccias and epiclastic, pyroclastic deposits. Basaltic andesite lavas contain Ca-rich plagioclase + clinopyroxene ± olivine with minor amounts of opaque minerals in a matrix comprised of microlites and glass; andesitic lavas are generally contain Ca

    The late Neogene to Quaternary Cappadocian Volcanic Province (CVP) in central Anatolia is one of the most impressive volcanic fields of Turkey because of its extent and spectacular erosionally sculptured landscape. The late Neogene evolution of the CVP started with the eruption of extensive andesitic-dacitic lavas and ignimbrites with minor basaltic lavas. This stage was followed by Quaternary bimodal volcanism. Here, we present geochemical, isotopic (Sr-Nd-Pb and δ18O isotopes) and geochronological (U-Pb zircon and Ar-Ar amphibole and whole-rock ages) data for bimodal volcanic rocks of the Niğde Volcanic Complex (NVC) in the western part of the CVP to determine mantle melting dynamics and magmatic processes within the overlying continental crust during the Quaternary. Geochronological data suggest that the bimodal volcanic activity in the study area occurred between ca. 1.1 and ca. 0.2 Ma (Pleistocene) and comprises (1) mafic lavas consisting of basalts, trachybasalts, basaltic andesites and scoria lapilli fallout deposits with mainly basaltic composition, (2) felsic lavas consisting of mostly rhyolites and pumice lapilli fall-out and surge deposits with dacitic to rhyolitic composition. The most mafic sample is basalt from a monogenetic cone, which is characterized by 87Sr/86Sr = 0.7038, 143Nd/144Nd = 0.5128, 206Pb/204Pb = 18.80, 207Pb/204Pb = 15.60 and 208Pb/204Pb = 38.68, suggesting a moderately depleted signature of the mantle source. Felsic volcanic rocks define a narrow range of 143Nd/144Nd isotope ratios (0.5126-0.5128) and are homogeneous in Pb isotope composition (206Pb/204Pb = 18.84-18.87, 207Pb/204Pb = 15.64-15.67 and 208Pb/204Pb = 38.93-38.99). 87Sr/86Sr isotopic compositions of mafic (0.7038-0.7053) and felsic (0.7040-0.7052) samples are similar, reflecting a common mantle source. The felsic rocks have relatively low zircon δ18O values (5.6 ± 0.6 ‰) overlapping mantle values (5.3 ± 0.3 %), consistent with an origin by fractional crystallization

    Full Text Available Earthquakes registering magnitudes Md = 4.5 and 4.7 struck the city of Konya, Central Anatolia, on 10–11 September 2009, causing very slight damages. The earthquake epicenters were located at the east of Sille District along the Konya Fault Zone, a dip-slip fault. The nature and seismicity of the fault zone indicates that it is capable of producing earthquakes of moderate magnitudes. This paper summarizes the geologic data along the fault zone and documents groundwater conditions and analyzes borehole and geotechnical data of the Konya city. The residential area of the city covers an area of approximately 1150 square kilometers and consists almost entirely of flat land except for a small part of rugged land in the southwestern corner. Groundwater and geotechnical data were collected and analyzed to evaluate the liquefaction potential of deposits under the Konya city. This preliminary investigation indicates that areas for liquefaction are generally limited to the eastern and east central parts of the city.

    Full Text Available Background: Onychomycosis is a world-wide public health concern in children, requiring epidemiological data for different regions for control and prevention. Aim: The aim of this study was to evaluate the predominant pathogens and risk factors for onychomycosis in school children living in Kayseri, Turkey. Methods: This study included 8122 school children, aged 5-16 years, living in the rural and urban areas around Kayseri. Onychomycosis was clinically classified as distal and lateral subungual (DLSO, proximal subungual, superficial white, endonyx and totally dystrophic onychomycosis. Nail samples from children with clinically diagnosed onychomycosis were collected, examined by direct microscopy and inoculated for culture study. The demographic features and possible risk factors were recorded and assessed by logistic regression models. Results: We clinically diagnosed onychomycosis in 152 out of 8,122 (0.18% school children. DLSO was the most frequent clinical diagnosis (120/152, 78.9%. Culture-positive onychomycosis was detected in 27/152 (17.7% children. The prevalence of culture-positive onychomycosis was determined as 0.33%. All culture-positive samples were only from toenails. The onychomycosis causative agents were dermatophytes in 17/27 cases (62.9%, including Trichophyton rubrum 12 (44.4%, Trichophyton mentagrophytes 1 (3.7%, Trichophyton tonsurans 1 (3.7% and Trichophyton spp. 3 (11.1% and yeasts in 10/27 cases (37.1%, including Candida glabrata 4 (14.8%, Candida parapsilosis 1 (3.7%, Trichosporon 2 (7.4% and Rhodotorula 3 (11.1%. Age, father′s occupation, number of siblings and rooms were statistically associated with the frequency of onychomycosis. Conclusions: Although to be prevalence of onychomycosis in school children in central Anatolia of Turkey seems very low degree, pediatric onychomycosis is a growing public health concern all over the world.

Vulnerability of the Cappadocia to desertification processes was also investigated with respect to the aridity, lithology dominated by tuffs and climate-process system and present land-use features of the district. The data analysis revealed that coefficients of variation (CV of the mean and maximum temperatures are the greatest in summer and the smallest in winter. Nevşehir and Kayseri environs are the most continental parts of the Cappadocia with a high inter-annual variability and low temperatures. Cappadocia is characterized with a continental rainfall regime having a maximum precipitation in spring. Variability of summer precipitation totals is greater than that of other seasons, varying from 65.7% to 78%. The CVs of the annual precipitation totals are about 18% at north and about 20% at south. Semi-arid and dry sub-humid or semi-humid climate types prevail over Cappadocia according to Thornthwaite’s moisture and Erinç’s aridity indices. Steppe is the dominant vegetation formation with sparse dry forests. The Cappadocia is vulnerable to the desertification processes due to both natural factors (e.g. degree of aridity, climate-process system, weathering of tuffs, erosion, climate change, etc. and human-involvement (e.g. land degradation and intensive tourism, etc.. In order to mitigate desertification and to preserve the historical and cultural heritages in Cappadocia, sustainable land-use management and tourism planning applications are urgently needed.

    Full Text Available Turkey is located within semi-arid climate zone and large portion of the country experience water deficits. Thus, efficient water use has become a significand issue in agricultural practices. Current global warming and climate change have aggravated such deficiencies. Konya province is located right at the center of Central Anatolia region and mostly groundwater is used in irrigations. Excessive groundwater withdrawals drop groundwaters levels and also increase energy costs. Although farmers pay quite high sums for energy, they were not using water efficiently and thus were not able to get desired benefits from the irrigations. In this study, irrigation practices of an irrigation cooperative were assessed and compared with optimum irrigation programs created through IRSIS irrigation scheduling software. It was concluded that all irrigation practices of the region were wrong and way behind the optimum ones.

    The Nigde Volcanic Complex (NVC) is a major Late Neogene-Quaternary volcanic centre within the Cappadocian Volcanic Province of Central Anatolia. The Late Neogene evolution of the NVC generally initiated with the eruption of extensive andesitic-dacitic lavas and pyroclastic flow deposits, and minor basaltic lavas. This stage was followed by a Quaternary bimodal magma suite which forms Na-alkaline/transitional basaltic and high-K calc-alkaline to alkaline silicic volcanic rocks. In this study, we present new geochemical, isotopic (Sr-Nd-Pb) and geochronological (Ar-Ar and U-Pb) data for the bimodal volcanic suite within the NVC. Recent data suggest that the eruption of this suite took place ranges between ~650 and ~220 ka (Middle-Late Pleistocene). Silicic rocks consisting of rhyolite and associated pumice-rich pyroclastic fall out and surge deposits define a narrow range of 143Nd/144Nd isotope ratios (0.5126-0.5127), and show virtually no difference in Pb isotope composition (206Pb/204Pb = 18.84-18.87, 207Pb/204Pb = 15.64-15.67 and 208Pb/204Pb = 38.93-38.99). 87Sr/86Sr isotopic compositions of the silicic (0.704-0.705) and basaltic rocks (0.703-0.705) are rather similar reflecting a common source. The most mafic sample from basaltic rocks related to monogenetic cones is characterized by 87Sr/86Sr = 0.704, 143Nd/144Nd = 0.5127, 206Pb/204Pb = 18.80, 207Pb/204Pb = 15.60 and 208Pb/204Pb = 38.68. These values suggest a moderately depleted signature of the mantle source. The geochronological and geochemical data suggest that NVC silicic and basaltic rocks are genetically closely related to each other. Mantle derived differentiated basaltic melts which experienced low degree of crustal assimilation are suggested to be the parent melt of the rhyolites. Further investigations will focus on the spatial and temporal evolution of Quaternary bimodal magma suite in the NVC and the genetic relation between silicic and basaltic rocks through detailed oxygen isotope analysis and (U

    In the Ereǧli-Bor Basin (Konya-Niǧde), Central Anatolia, bituminous shale sequence with thickness ranging between 72 and 160 m occurs in lacustrine deposits of Upper Miocene-Pliocene age. The live oil has also been observed in this bituminous shale sequence. Rock-Eval/TOC, GC and GC-MS analyses were conducted on selected bituminous shale samples from four borehole (key-12/1, key-12/2, key-12/3 key-12/4) and one crude oil sample from a borehole (key-12/2) in the basin. In this study, organic matter type, maturity and depositional environment of bituminous shale are evaluated and the origin of crude oil is determined by the bituminous shale-crude oil correlation. The total organic carbon (TOC) values of the bituminous shale samples range from 1.21-13.98 wt% with an average TOC value of 4.75wt%. The bituminous shale sequence is characterized by high HI (127-662 mg HC/g TOC) and low OI (7-50 mgCO2/TOC). Tmax varies from 332-419ᵒC. Very low Pr/Ph ratios of bituminous shale (0.09-0.22) are indicative of anoxic depositional conditions. C27 is dominate sterane for bituminous shale and crude oil samples with C27>C29>C28. Normal steranes are more dominant compare to iso- and diasteranes. Ouite high sterane/hopane ratios (1.14-2.70) indicate dominant algal organic matter input for bituminous shale and source rock of crude oil. C31R/hopane ratio for bituminous shale and crude oil samples are very low (0.09-0.13) and these ratio show a lacustrine depositional envirronment for bituminous shale and source rock of crude oil. Sterane and terpane distributions of bituminous shale and crude oil are very similar. A very good correlation in terms of biomarker between bituminous shale and crude oil samples indicate that source rock of crude oil is bituminous shale. The 22S/(22R + 22S) C32 homohopane ratios of bituminous shale and crude oil samples are found to be 0.56 and 0.61, indicating that homohopane isomerization has attained equilibrium and bituminous shale and crude oil are

    The Neotectonics period in western Anatolia Extended Terrain, Turkey (WAET) may have initiated in late Oligocene following the Eocene Alpine collision which produced the Izmir-Ankara suture zone. The Western Anatolia Shear Zone (WASZ) bounds the WAET to the east. The shear zone contains mostly normal faults in the vicinity of the Gulf of Gokova. However, its movement is mostly oblique slip from the vicinity of Tavas towards the Lake of Acigol where it makes a northward bend and possibly joins the Eskisehir fault zone to the north of the town of Afyon. The shear zone forms the southern and eastern margins of the Kale-Tavas, Denizli and Acigol basins. The shear zone is similar in its structural/tectonics setting to the Eastern California Shear zone (ECSZ) of the Basins and Ranges of North America Extended terrain which is also composed of many normal to oblique-slip faults and separates two extended terrains with different rates of extension. Western Anatolia experienced many devastating earthquakes within the last 2000 years. Many of the ancient Greek/Roman city states, including Ephesus, Troy, and Hierapolis were destroyed by large historical earthquakes. During the second half of the 20th century, the region experienced two major large earthquake giving normal fault focal mechanism solutions. They are the 1969, M=6.9 Alasehir and the 1970, M=7.1 Gediz earthquakes. These earthquakes had caused substantial damage and loss of life in the region. Therefore, a comprehensive understanding of the kinematics of the Cenozoic extensional tectonics and earthquake potential of the WASZ in the region, is very important, especially since the fault zone is very close to the major towns in eastern part of western Turkey, such as Mugla, Denizli, Sandikli, Dinar and Afyon.

    2016-04-01

    East Anatolia Region (EAR) is one of the high Plateau which is occurred with north-south compressional regime formed depending on continent-continent collision between Eurasia and Arabia plates (Şengör and Kidd, 1979). Recent studies have revealed that last oceanic lithosphere in the EAR have completely depleted to 20 million years ago based on fission track ages (Okay et al. 2010). Our initial studies suggest that extensively volcanic activity in the EAR peaked in the Pliocene and continued in the same productivity throughout Quaternary. Voluminous basaltic lava plateaus and basaltic lavas from local eruption centers occurred as a result of high production level of volcanism during the Pliocene time interval. In order to better understand the spatial and temporal variations in Pliocene basaltic volcanism and to reveal isotopic composition, age and petrologic evolution of the basaltic volcanism, we have started to study basaltic volcanism in the East Anatolia within the framework of a TUBITAK project (project number:113Y406). Petrologic and geochemical studies carried out on the Pliocene basaltic lavas indicate the presence of subduction component in the mantle source, changing the character of basaltic volcanism from alkaline to subalkaline and increasing the amount of spinel peridotitic melts (contributions of lithospheric mantle?) in the mantle source between 5.5-3.5 Ma. FC, AFC and EC-AFC modelings reveal that the while basaltic lavas were no or slightly influenced by crustal contamination and fractional crystallization, to more evolved lavas such as bazaltictrachyandesite, basalticandesite, trachybasalt might have been important processes. Results of our melting models and isotopic analysis data (Sr, Nd, Pb, Hf, 18O) indicate that the Pliocene basaltic rocks were derived from both shallow and deep mantle sources with different melting degrees ranging between 0.1 - 4 %. The percentage of spinel seems to have increased in the mantle source of the basaltic

    The Lake District, located in the SW Anatolia region of Turkey, hosts a number of lakes with unique water chemistry. Among them, Lake Acigol, Lake Salda and Lake Yarisli display extreme biogeochemical conditions. In terms of their water chemistry and diverse prokaryotic community, each lake sets a great example for microbially mediated reactions (e.g carbonate precipitation). Lake Acigol (average pH around 8.6) is known for hypersaline and alkaline water chemistry. Lake Salda (average pH around 9.1) is known for its hydromagnesite beaches, clayey-hydromagnesite shoreline and ancient-modern stromatolite formations as well as being a model for Mars. For the first time, Lake Yarisli having alkaline conditions with an average pH value of 9.5 is investigated for its geochemistry and geobiology during this study. Algal bloom and well developed cyanobacterial mats are visible on shallow waters along the Eastern shoreline of the lake. In scope of elucidating complex bio/geochemical reactions that regulate C, S and O cycles in the extreme conditions of these lakes, water, surface sediment and shallow core samples were collected. For the first time, prokaryotic diversity of Lake Acigol, Salda and Yarisli were determined by Next-Generation Sequencing (NGS) during this study (Balci et al., 2013). Preliminary results revealed the total number of bacterial classes determined for Lake Acigol, Lake Salda and Lake Yarisli as 22, 19 and 19; respectively. Lake Acigol, Salda and Yarisli are mostly dominated by bacterial classes of Alphaproteobacteria (68.2%, 25.6% and 1.9%; respectively), Cyanobacteria (10.2%, 5.3% and 92.9%; respectively), Bacilli (9.6%, 23.7% and 0.45%; respectively), Gammaproteobacteria (6.1%, 39.6% and 4.3%; respectively) and Actinobacteria (2.7%, 1.8% and 0.06%; respectively). The total number of archaeal classes determined for Lake Acigol, Lake Salda and Lake Yarisli are 8, 7 and 6; respectively. Common most dominant archaeal classes of Lake Acigol, Lake Salda

In this study, for determining the geodynamical behaviors of seismically active tectonic structures of Gediz and Büyük Menderes grabens which are located in Western Anatolia (Turkey) graben system, the mass changes were examined by processing of GNSS and microgravity data. Besides, after modeling the GNSS velocity by Coulomb stress analysis, the stress distributions were investigated for these models. Therefore, first of all, the changes of gravity and the vertical components of GNSS velocity values were evaluated together with a statistical method. Secondly, GNSS velocities were calculated relative to the main tectonic structures and the stress changes of tectonic structures were obtained at different depths with Coulomb stress analysis by using these velocities and all results were evaluated with the earthquakes that had occurred in the study area. Consequently, the crustal movements of the areas located at the GNSS stations and their surroundings were put forwarded as in compensation or uncompensation concept of surface and subsurface loadings due to the mass or groundwater effects by using both microgravity and GNSS measurements, as an initial study on Western Anatolia graben system.

    Brucellosis is an important public-health problem in Turkey. Children may constitute 20 to 30% of all brucellosis cases in the world, especially in the endemic regions. Data on the seroprevalence of brucellosis in childhood are very limited. In this study, we aimed to evaluate the seroprevalence of brucellosis among a child population. One thousand one hundred and ten subjects were included in the study. Blood samples were collected and tested with Rose Bengal (RB) and standard tube agglutination test (SAT). RB test results were positive for 6 patients, and SAT was negative for all patients. Our findings suggest that seroprevalence of brucellosis is decreasing in Middle Anatolia due to a new cattle vaccination and eradication programme which was initiated in 2009.

    Full Text Available Monthly average daily data of climatic conditions over the period 1994-2003 of cities in the east Anatolia region of Turkey is presented. Regression methods are used to fit polynomial and trigonometric functions to the monthly averages for nine parameters. The parameters namely temperature, maximum-minimum temperature, relative humidity, pressure, wind speed, rainfall, solar radiation and sunshine duration are useful for renewable energy applications. The functions presented for the parameters should enable determination of specific parameter values and prediction of missing values. They also provide some insight into the variation of these parameters. The models developed can be used in any study related to climatic and its effect on the environment and energy.

    The Central Anatolian orogenic plateau is represented by young volcanism, rapid plateau uplift and distinctive (past and active) tectonic deformation. In this study, we consider observational data in terms of regional present-day geodynamics in the region. The residual topography of Central Anatolia was derived to define the regional isostatic conditions according to Airy isostasy and infer the potential role of `dynamic topography'. 2-D thermomechanical forward models for coupled mantle-lithosphere flow/deformation were conducted along an N-S directional profile through the region (e.g. northern/Pontides, interior and southern/Taurides). These models were based on seismic tomography data that provide estimates about the present-day mantle thermal structure beneath the Anatolian plate. We compare the modelling results with calculated residual topography and independent data sets of geological deformation, gravity and high surface heat flow/widespread geothermal activity. Model results suggest that there is ˜1 km of mantle flow induced dynamic topography associated with the sublithospheric flow driven by the seismically inferred mantle structure. The uprising mantle may have also driven the asthenospheric source of volcanism in the north (e.g. Galatia volcanic province) and the Cappadocia volcanic province in the south while elevating the surface in the last 10 Myr. Our dynamic topography calculations emphasize the role of vertical forcing under other orogenic plateaux underlain by relatively thin crust and low-density asthenospheric mantle.

    Potential geothermal areas are identified through investigation of spatial relations between geothermal occurrences and their surrounding geological phenomena in western Anatolia, Turkey. The identification is based on only publicly available data. It is expected that the study will guide further preliminary investigations performed for large areas having limited information. Magnetic anomaly, Bouger gravity anomaly, earthquake epicenter and lineament datasets are used for the analysis. The first is used without any modification whereas the rest are utilized to extract three evidence maps; distance to major grabens, Gutenberg-Richter b-value and distance to lineaments, respectively. Predictor maps are produced from these evidence maps as well as from the unprocessed magnetic anomaly map by applying two different binarization procedures. From each binarization procedure a favorability map is produced separately using Index Overlay (IO) and Weights of Evidence (WofE) methods. The findings reveal that weighting predictor maps according to spatial association between evidence maps and training points lead to more accurate prediction in both WofE and IO methods. The potential areas in the final maps are Aydin, Denizli, Manisa, Balikesir and Kutahya of which first two have been explored and exploited, and thus found to be favorable, while the rest are nearly unexplored.

    Electron spin resonance (ESR) spectroscopy technique has been employed to date the aragonitic fresh-water gastropod shells (Melanoides curvicosta) collected from Soma (Manisa) district (West Anatolia) of Turkey. The influence of the annealing temperature and {gamma}-radiation dose on dating signal at g = 2.0016 is investigated. The thermal stability and dose response of the ESR signals were found to be suitable for an age determination using a signal at g = 2.0016. The activation energy (E), frequency factor (s) and mean-lifetime ({tau}) at 15 deg. C of the g = 2.0016 center were calculated to be 1.67 {+-} 0.01 eV (3.6 {+-} 0.7) x 10{sup 13} s{sup -1} and 2.02 x 10{sup 8} years, respectively. The ESR signal growth curve on additional {gamma}-irradiation has been best fitted by an exponential saturation function. Based on this model, accumulated dose (AD) value for dating is obtained. We have determined the ESR age of the terrestrial gastropods to be 2.57 {+-} 0.30 Ma. The results show that the ESR age falls into the Late Pliocene (Romanian) epoch of the geological time scale, which agreed with the paleoecological and paleogeographic distribution and stratigraphic level of the fauna.

    Full Text Available In this issue of the Canadian Respiratory Journal, Gulmez et al (pages 287-290 review the presentation, management and outcome of malignant mesothelioma in central Anatolia, Turkey. There is nothing particularly new about the disease here; it presents with chest pain, dyspnea and pleural effusion, is diagnosed by biopsy and has a miserable outcome whatever is done for it, just like malignant mesothelioma in Canada. Mesothelioma in Anatolia is unusual in that it is very common, with an approximately equal sex distribution, and frequently occurs in relatively young people. The reasons for this are not a mystery. Anatolia is a volcanic area; there is a lot of asbestos on or near the surface, and it is widely used as construction material, in painting, and as insulation (pages 287-290! Asbestos related disease is due to environmental, not occupational exposure, and exposure is more intense and occurs at an earlier age than in Canada. Not only that, but some areas of Anatolia are rich in erionite, and people build homes in and on erionite-bearing rocks. Erionite is apparently something like asbestos but worse in terms of carcinogenicity (1, perhaps because its crystals have large surface areas, and areas with erionite have an even higher incidence of mesothelioma.

  8. Water Management For Drip Irrigated Corn In The Arid Southeastern Anatolia Project Area In Turkey

    Yazar, A.; Gencel, B.

    Microirrigation has the potential to minimize application losses to evaporation, runoff and deep percolation; improve irrigation control with smaller, frequent applications; supply nutrients to the crop as needed; and improve crop yields. The Southeastern Anatolia Project (GAP), when completed, 1.7 million ha of land will be irrigated. Wa- ter supplies are limited, and traditional irrigation practices result in high losses and low irrigation efficiences. This study was conducted to evaluate surface drip irrigation on crop performance. The effect of irrigation frequency and amount on crop yield, yield components, water use, and water use efficiency of corn (Zea mays L., PIO- 3267) were investigated in the Harran Plain in the arid Southeastern Turkey on a clay textured Harran Soil Series. Irrigation frequencies were once in three-day, and once in six-day; irrigation levels varied from full (I-100), medium (I-67; 2/3rd of full), and low (I-33; 1/3rd of full). The full irrigation treatment received 100% of the cumula- tive evaporation within the irrigation interval. Liquid nitrogen was injected into the irrigation water throughout the growing season. Treatments received the same amount of fertilizers. Highest average corn grain yield (11920 kg/ha) was obtained from the full irrigation treatment (I-100) with six-day irrigation interval. Irrigation intervals did not affect corn yields; however, deficit irrigation affected crop yields by reducing seed mass, and the seed number. Maximum water use efficiency (WUE) was found as 2.27 kg/m3 in the I-33 treatment plots with three-day irrigation interval. On the clay soil at Harran, irrigation frequencies are less critical than proper irrigation management for drip irrigation systems to avoid water deficits that have a greater effect on corn yields. The results revealed that about 40% water saving is possible with drip irrigation as compared to traditional surface irrigation methods in the region.

    In the evolutionary history of modern humans, Anatolia acted as a bridge between the Caucasus, the Near East, and Europe. Because of its geographical location, Anatolia was subject to migrations from multiple different regions throughout time. The last, well-known migration was the movement of Turkic speaking, nomadic groups from Central Asia. They invaded Anatolia and then the language of the region was gradually replaced by the Turkic language. In the present study, insertion frequencies of 10 Alu loci (A25 = 0.07, APO = 0.96, TPA25 = 0.44, ACE = 0.37, B65 = 0.57, PV92 = 0.18, FXIIIB = 0.52, D1 = 0.40, HS4.32 = 0.66, and HS4.69 = 0.30) have been determined in the Anatolian population. Together with the data compiled from other databases, the similarity of the Anatolian population to that of the Balkans and Central Asia has been visualized by multidimensional scaling method. Analysis suggested that, genetically, Anatolia is more closely related with the Balkan populations than to the Central Asian populations. Central Asian contribution to Anatolia with respect to the Balkans was quantified with an admixture analysis. Furthermore, the association between the Central Asian contribution and the language replacement episode was examined by comparative analysis of the Central Asian contribution to Anatolia, Azerbaijan (another Turkic speaking country) and their neighbors. In the present study, the Central Asian contribution to Anatolia was estimated as 13%. This was the lowest value among the populations analyzed. This observation may be explained by Anatolia having the lowest migrant/resident ratio at the time of migrations.

    In this research, were used 3 triticale varieties (Tacettinbey, Karma 2000 and Presto), one durum (Sariçanak 98) and one bread (Nurkent) wheat varieties. The study, was randomized as complete block design with four replications in 4 location (southeastern Anatolia of Turkey) and under rainfed conditions during the growing season 2010-2011. With an analysis of variance, significant differences were determined among locations, genotypes and genotype x location interactions at the 1% and 5% level. Following results were obtained: period to heading 109 till 113 days, plant height between 96 and 127 cm, hectoliter weight between 68.2 and 81.7 kg/hl, thousand grain weight between 32.9 and 42.7 g, protein content between 13.3 and 14.7%, humidty kernels at harvest between 9.2 and 9.5% and grain yield between 4409 and 6119 kg/ha(-1). The highest grain yield was obtained with Sariçanak 98 (durum wheat variety) while the best thousant grain weight was obtained by the triticale variety Tacettinbey. The triticale variety Karma 2000 showed higher protein content (14.7%) than other the other triticale varieties as well as durum and bread wheat varieties included trial. For the Southeastern Anatolia Region he results of this study demonstrated that the grain yield of triticale varieties were lower compared to common wheat. Nevertheless the triticale grain yield was higher than these of durum and bread wheat varieties under the more extrem (higher temperature and drought) growing conditions of the Kiziltepe region. For triticale the highest mean grain yield has been obtained fwith the variety Tacettinbey which is spring type. New sping type vatieties are more suitable than wheat for the more extreme growing conditions of the Southeastern Anatolia Region.

    Coexistence of thermal springs, travertine deposits and tectonic activity is a recurring feature for most geothermal areas. Although such a certainty, their relationships are debated mainly addressing on the role of the tectonic activity in triggering and controlling fluids flow and travertine deposition. In this paper, we present the results of an integrated study carried out in a geothermal area located in western Anatolia (Turkey), nearby the well-known Pamukkale area (Denizli Basin). Our study focused on the relationships among hydrothermal fluids circulation, travertine deposition and tectonic activity, with particular emphasis on the role of faults in controlling fluids upwelling, thermal springs location and deposition of travertine masses. New field mapping and structural/kinematics analyses allowed us to recognize two main faults systems (NW- and NE-trending), framed in the Neogene-Quaternary extensional tectonic evolution of western Anatolia. A geo-radar (GPR) prospection was also provided in a key-area, permitting us to reconstruct a buried fault zone and its relationships with the development of a fissure-ridge travertine deposit (Kamara fissure-ridge). The integration among structural and geophysical studies, fluids inclusion, geochemical, isotopic data and 230 Th/238 U radiometric age determination on travertine deposits, depict the characteristics of the geothermal fluids and their pathway, up to the surface. Hydrological and seismological data have been also taken in account to investigate the relation between local seismicity and fluid upwelling. As a main conclusion we found strict relationships among tectonic activity, earthquakes occurrence, and variation of the physical/chemical features of the hydrothermal fluids, presently exploited at depth, or flowing out in thermal springs. In the same way, we underline the tectonic role in controlling the travertine deposition, making travertine (mainly banded travertine) a useful proxy to reconstruct the

    A radiological survey of the granitoid areas throughout Western Anatolia was conducted during 2007-14. As a part of this radiological survey, this article presents results obtained from Eğrigöz pluton, which lies in the northeastern region of Western Anatolia. In the investigated area, the activity measurements of the natural gamma-emitting radionuclides ((226)Ra, (232)Th and (40)K) in the granitic rock samples and soils have been carried out by means of the NaI(Tl) gamma-ray spectrometry system. The activity concentrations of the relevant natural radionuclides in the granite samples appeared in the ranges as follows: (226)Ra, 28-95 Bq kg(-1); (232)Th, 50-122 Bq kg(-1) and (40)K, 782-1365 Bq kg(-1), while the typical ranges of the (226)Ra, (232)Th and (40)K activities in the soil samples were found to be 7-184, 11-174 and 149-1622 Bq kg(-1), respectively. Based on the available data, the radiation hazard parameters associated with the surveyed rocks/soils are calculated. The corresponding absorbed dose rates in air from all those radionuclides were always much lower than 200 nGy h(-1) and did not exceed the typical range of worldwide average values noted in the UNSCEAR (2000) report. Furthermore, the data are also used for the mapping of the surface soil activity of natural radionuclides and the corresponding gamma dose rates of the surveyed area.

    2017-01-01

    New (U-Th)/He thermochronology data from the syn-extensional granitoids in the central part of the Menderes Massif in western Turkey reveal a minimum slip rate of 12.5 km/Myr along the Alasehir detachment ( 14° dip angle) and denudation rates between 1.75 km/Myr and 3.25 km/Myr between 4 Ma and 2 Ma. These values suggest relatively fast exhumation of the Central sub-massif, associated with cooling rates between 53 °C/Myr and 128 °C/Myr, which are higher than the estimated footwall cooling rates (60 °C/Myr to 120 °C/Myr) from the Northern sub-massif. Based on the initial crystallization ages of the syn-extensional granitoid intrusions and their exhumation-related cooling ages, our thermochronological findings suggest that the Central sub-massif in Menderes underwent accelerated uplift and faster exhumation in the latest Cenozoic than the Northern and Southern sub-massifs. This latest doming and rapid extension of the Central sub-massif was associated with the asthenospheric upwelling beneath the region and the related Na-alkaline, Kula volcanism. Our results indicate that the Menderes Massif has had a diachronous uplift and cooling history during its extensional tectonic evolution in the late Cenozoic. Thermal weakening of the young orogenic crust in western Anatolia via both lithospheric and asthenospheric melting episodes and magmatism produced higher than normal geothermal gradients and played a significant role in core complex formation.

    2017-02-01

    Full Text Available Background: Honey, a natural sweetener, is produced from the nectar of many plants. The pollen diversity, physicochemical properties, and antimicrobial activities were analyzed in honey samples from Mardin (Southeastern Anatolia. Methods: The melissopalynological method was used to identify and enumerate the pollen granules. Analytical methods and agar well diffusion assays were employed for the determination of some quality parameters and the antimicrobial potential of honey samples, respectively. Results: The pollen composition consisted of 27 taxa belonging to 13 families. The origins of all honey were determined as the multifloral sources. The most predominant taxa were mainly Hedysarum sp., Carduus sp., Melissa officinalis, Gossypium hirsitum, Paliurus spina-christi, Salix sp. and Pimpinella anisum. The secondary pollen taxa were Hedysarum sp., Trifolium sp., Astragalus sp., Salix sp., Paliurus spina-christi, Asphodeline sp., Centaurea sp., Carduus sp., Zea mays and Cistus sp., respectively. Asphodeline sp. as a secondary pollen taxon in a honey sample could be considered as the first report. The pH, total acidity, brix, refractive index, electrical conductivity, moisture and L, a, b values of the samples varied from 3.75 to 4.28, 30 to 42, 67.3 to 85.70, 1.45 to 1.50, 12.40 to 31.61, 0.24 to 0.90, 47.81 to 57.59, -0.94 to 4.31, 20.37 to 31.28, respectively. Antimicrobial activities of the honey specimens were also effective on five bacterial species and two yeast species. Conclusions: Honey samples from Southeastern Anatolia revealed a good diversity of pollen granules. The rich multiflora of honey increases not only its nutritional quality as well as antimicrobial potential on various clinically important microorganisms.

    Arsenic (As) contamination in terrestrial geothermal systems has been identified in many countries worldwide. Concentrations higher than 0.01 mg/L are detrimental to human health. We examined potential consequences for As contamination of freshwater resources based on hydrogeochemical investigations of geothermal waters in deep wells and hot springs collected from western Anatolia, Turkey. We analyzed samples for major ions and trace element concentrations. Temperature of geothermal waters in deep wells showed extreme ranges (40 and 230 °C), while, temperature of hot spring fluids was up to 90 °C. The Piper plot illustrated two dominant water types: Na-HCO3(-) type for geothermal waters in deep wells and Ca-HCO3(-) type for hot spring fluids. Arsenic concentration ranged from 0.03 to 1.5mg/L. Dominance of reduced As species, i.e., As(III), was observed in our samples. The Eh value ranged between -250 and 119 mV, which suggests diverse geochemical conditions. Some of the measured trace elements were found above the World Health Organization guidelines and Turkish national safe drinking water limits. The variation in pH (range: 6.4-9.3) and As in geothermal waters suggest mixing with groundwater. Mixing of geothermal waters is primarily responsible for contamination of freshwater resources and making them unsuitable for drinking or irrigation.

    Increasing demands for water and quality concerns have highlighted the importance of accounting for household perceptions before local municipalities rehabilitate existing water infrastructures and bring them into compliance. We compared different willingness-to-pay (WTP) estimates using household surveys in the southern Anatolian region of Turkey. Our study is the first of its kind in Turkey. Biases resulting from sample selection and the endogeneity of explanatory variables were corrected. When compared to a univariate probit model, correction of these biases was shown to result in statistically significant findings through moderate reductions in mean WTP.

    The aim of this cross-sectional study was to estimate the risk of hypertension in 1106 Caucasian individuals aged 20-69 years in Yozgat Province, using the Framingham Hypertension Risk Prediction Score (FHRPS). According to FHRPS, average risk of developing hypertension over 4 years was 6.2%. The participants were classified into low- (10%) risk groups. The percentage of participants that fell into these groups was 59.4%, 19.8% and 20.8% respectively. The proportion of participants in the high-risk group was similar to the 4-year incidence of hypertension (21.3%) in the Turkish population. Regression analysis showed that high salt consumption and low educational level significantly increased the risk of hypertension. Economic level, fat consumption, life satisfaction, physical activity, and fruit and vegetable consumption were not correlated with risk of hypertension. This study shows that FHRPS can also be used for predicting risk of hypertension in Central Anatolia.

    The sustainable use of agricultural lands is significantly affected by the implemented management and land processing methods. In sugar beet and wheat cropping, because the agronomic characteristics of plants are different, the tillage methods applied also exhibit significant variability. Soil quality concept is used, as a holistic approach to determining the effects of these applications on the sustainable use of soil. Agricultural soil quality evaluation is essential for economic success and environmental stability in rapidly developing regions. At present, a variety of methods are used to evaluate soil quality using different indicators. This study was conducted in one of the most important irrigated agriculture areas of Çumra plain in Central Anatolia, Turkey. In the soil under sugar beet and wheat cultivation, 12 soil quality indicators (aggregate stability (AS), available water capacity (AWC), surface penetration resistance (PR0-20), subsurface penetration resistance (PR20-40), organic matter (OM), active carbon (AC), potentially mineralizable nitrogen (PMN), root health value (RHV), pH, available phosphorus (AP), potassium (K), and macro-micro elements (ME) (Mg, Fe, Mn, and Zn)) were measured and scored according to the Cornell Soil Health Assessment (CSHA) and the Soil Management Assessment Framework (SMAF). The differences among 8 (AS, AWC, PR0-20, PR20-40, AC, PMN, AP, and ME) of these 12 soil quality characteristics measured in two different plant cultivation were found statistically significant. The result of the soil quality evaluation with scoring function in the examined area revealed a soil quality score of 61.46 in the wheat area and of 51.20 in the sugar beet area, which can be classified as medium and low, respectively. Low soil quality scores especially depend on physical and biological soil properties. Therefore, improvement of soil physical and biological properties with sustainable management is necessary to enhance the soil quality in the

    A 601 m long core was drilled in Lake Acigöl located in an extensional basin in SW Anatolia (Turkey). The alternation of carbonates relatively rich in evaporites, siliciclastic particles and fossils (ostracods, gastropods and bivalves) gives to the sequence a high potential for palaeoclimatic record. The Acigöl sequence is younger than 3.4 Ma, the oldest age determination recorded for lacustrine successions elsewhere in SW Anatolia (van den Hoek Ostende, 2015). The first paleomagnetic investigations show numerous reverse polarities implying that two third of the sequence is older than 0.78 Ma (Brunhes/Matuyama transition) with a base dating back to 1.7 Ma or more. Indeed, although Jaramillo subchron (from 0.9 to 1.06 Ma) is well recorded, uncertainty remains for the Odulvaï subchron (from 1.78 to 2 Ma) which is not yet robustly identified. The age model will be soon completed by radiometric dating of a tephra found in the sequence and by authigenic 10Be/9Be dating. Detrital proxies (such as magnetic susceptibility) versus biological proxies will allow discrimination between tectonic and climatic signals and may reveal the response of terrestrial ecosystems to the mid-Pleistocene climatic transition.

    This study aimed to investigate the prevalence of various cognitive disorders in the older population (age 55 years and above) of Eskisehir, Turkey, by conducting a cluster sampled door-to-door survey. A total of 3100 inhabitants were screened with the Mini-Mental State Examination (MMSE) and a questionnaire concerning demographic, occupational and social data. Individuals (n=320) with MMSE scores of 25 were assessed according to the 10th Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and were investigated in the more detailed phase 2 study. The overall prevalence of dementia was 8.4%, although it ranged from 2.2% among those aged 55-59 years to 5.3% among those aged 60-64 years, and to 30.4% among those aged 75 or above. Vascular dementia was the most common type (51.1%), followed by Alzheimer's dementia (48.8%). In a very small proportion of individuals (0.1%), dementia was due to other causes such as B12 deficiency, a tumour or hydrocephalus. Significant risk factors for dementia were female sex, low education, age, living in a rural area and a family history of dementia.

    Sumac (Rhus coriaria L.) and terebinth (Pistacia terebinthus L.) are two important spice plants of south eastern Anatolia, Turkey. Nutrients, physical properties including moisture, ash, dry matter, protein, fatty oil and essential oil content, along with Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Na, Ni, Pb, Zn and characteristics of fruit sizes and fatty acid compositions of both plants were determined from ripe fruits. The free fatty acid content was determined in the fruit oil, and the main fatty acids of sumac and terebinth were identified by gas chromatography/mass spectrometry. They included oleic, linoleic, palmitic and stearic acids in a ratio of 37.7% and 34.8%, 27.4% and 17.3%, 21.1% and 21.7% and, 4.7% and 2.5%, respectively. The fruits of both plants were rich in oil, fatty acids and minerals, suggesting that they are valuable for using in food. The data may also be useful for the evaluation of nutritional information.

    The ancient Miletus which were one of the most important city of ancient Iona, are today of great value from cultural standpoint of Turkey. Miletus, situated near the village of Balat in the present district of Soke was founded on a peninsula, approximately 2.5 km long. In the Byzantine period, the city boundaries were quite reduced. In 1424 Miletus was taken inside of the Ottoman Empire and was completely abandoned in the 17th century. Ancient Miletus excavation studies were first begun in 1899 by in Berlin Museum and interrupted during the World War I. At present, the extensive restoration works in Ilyas Bey Complex has applied as a project since 2006. Ilyas Bey Complex that includes Mosque, Medresah and baths situated on the archaeological area in ancient Miletus. Impressive Mosque built in 1404 by Ilyas Bey, Emir of Menteseogullari founded in 1279 and the complex was named after him, is one of the most remarkable buildings of mid-age Miletus. There are two main purposes of the study are (1) to determine archaeological remains of the study area underneath Ilyas Bey Complex and (2) to define the nature of main rock unit and their sources in the vicinity or Aegean region. After preliminary archaeometrical studies, acquired GPR profile data paralleled each other in Ilyas Bey Mosque and its around, Medresah Courtyard and inner Courtyard of the Mosque. After processing 2D parallel GPR profiles, we constructed 3D data volume by lining processed 2D profiles up to correlate remain signatures from each profile for each studied area. It was obtained transparent 3D visualisation of GPR data by assigning a new colour scale for the amplitude range and by constructing a new opacity function instead of the linear opacity function. Therefore we could successfully image the archaeological remains in an interactive transparent 3D volume and its sub-volumes, starting at different depth levels or limited profiles.

    Bronze weapons (VII cen BC) found during the archaeological excavation of the Ayanis fortress (lake Van, eastern Anatolia, Turkey) are investigated in order to determine their chemical composition and metallurgical features as well as to identify the micro-chemical and micro-structural nature of the corrosion products grown during long-term burial. Small fragments were sampled from the artefacts and analysed by means of the combined use of optical microscopy (OM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The results show that the bronze artefacts have been manufactured by using alloys with a controlled and refined chemical composition demonstrating the high level metallurgical competence and skill of the Urartian craftsmen and artists. Furthermore, the micro-structural and metallurgical investigations evidence the presence of equiaxed grains in the matrix, indicating that the artefact were produced by repeated cycles of mechanical shaping and thermal annealing treatments to restore the alloy ductility. From the degradation point of view, the results show the structures and the chemical composition of the stratified corrosion layers (i.e. the patina) where the copper or tin depletion phenomenon is commonly observed with the surface enrichment of some elements coming from the burial soil, mainly Cl, which is related to the high concentration of chlorides in the Ayanis soil. The results reveal also that another source of degradation is the inter-granular corrosion phenomenon likely increased by the metallurgical features of the alloys caused by the high temperature manufacturing process that induces crystallisation and segregation phenomena along the grain boundaries.

  10. Bioaccumulation of metals in common carp (Cyprinus carpio L.) from water bodies of Anatolia (Turkey): a review with implications for fisheries and human food consumption.

    Although fish is widely consumed by humans for its nutritional properties, accumulation of heavy metals can pose serious health hazards. Widespread common carp Cyprinus carpio is cultured worldwide and represents an economically important species for fisheries in several countries. These include Turkey, where C. carpio often makes for a large part of the sales of the locally marketed fish and also for a traditional dish. This study provides a review of bioaccumulation of metals in tissues of C. carpio from water bodies of Anatolia and also includes reference to worldwide studies. From 42 water bodies across the region, 27 metals in total were studied, of which Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were the most widely analysed, mainly in the muscle, liver and gill tissues. Amongst the potentially toxic metals, Cd, Cr and Pb occurred in several water bodies at concentrations not only above maximum allowed limits but also higher relative to other water bodies worldwide, even though As, Hg and Ni were also sometimes present at potentially hazardous concentrations. The essential metals Cu, Fe, Mn, Se and Zn were detected at various concentrations, with the latter two occasionally above limit. All water bodies flagged as having especially critical (i.e. above limit) concentrations of toxic metals supported C. carpio fisheries from highly populated regions, raising concern about food safety and calling for preventative measures. Given the significantly lower bioaccumulation levels in the muscle relative to the liver and gill tissues, it is suggested that consumption of C. carpio as fillets may be safer than after processing into e.g. meat balls and sausages. The limits of 1.0 μg/g for Cr and 1.15 μg/g for Se, currently lacking from the Turkish food safety legislation, are proposed, and it is suggested that a similar meta-analytical approach as adopted in this study may benefit other countries where C. carpio represents an important fisheries resource.

    Better understanding of the factors controlling sediment load at a catchment scale can facilitate estimation of soil erosion and sediment transport rates. The research summarized here enhances understanding of correlations between potential control variables on suspended sediment loads. The Soil and Water Assessment Tool was used to simulate flow and sediment at the Ankara River basin. Multivariable regression analysis and principal component analysis were then performed between sediment load and controlling variables. The physical variables were either directly derived from a Digital Elevation Model or from field maps or computed using established equations. Mean observed sediment rate is 6697 ton/year and mean sediment yield is 21 ton/y/km² from the gage. Soil and Water Assessment Tool satisfactorily simulated observed sediment load with Nash-Sutcliffe efficiency, relative error, and coefficient of determination (R²) values of 0.81, -1.55, and 0.93, respectively in the catchment. Therefore, parameter values from the physically based model were applied to the multivariable regression analysis as well as principal component analysis. The results indicate that stream flow, drainage area, and channel width explain most of the variability in sediment load among the catchments. The implications of the results, efficient siltation management practices in the catchment should be performed to stream flow, drainage area, and channel width.

    Toxic gases evolving from the soil in urbanized peatland regions constitute a serious hazard since buildings may be subject to the direct ingress of volatiles into the structures. Peat formed in swamp and rarely exposed to subaerial conditions has been associated with the development of the folded foreland of the Quaternary Kayseri pull-apart basin. The peat deposit is extensively urbanized but so far no studies have evaluated the extent of the ground gas hazard. In this paper, the geology, petrography and chemical variation of the Kayseri peat deposit have been studied in order to predict the public health risk from the land gases’ behaviour, especially in soil gases. The main volatile species detected are methane (CH4), hydrogen sulphide (H2S) and carbon dioxide (CO2), all of which are highly toxic. The primary means of gas entry is directly from the ground through the floors, walls, and especially subsurface telephone cable pipes. Indoor vents emit 1000–70,000 ppm CH4, 330–49,000 ppm CO2 and 3.8–6.5 ppm H2S in soil and subsurface pipes; concentrations high enough to present an acute respiratory hazard to persons close to the vents.

    Freshwater Lake Ulubat (c. 1.5 m deep and c. 138 km{sup 2}) receives sediment from a 10.414 km{sup 2} area in the seismically active Susurluk Drainage Basin (SDB) of NW Turkey. The B and trace element contents of the lake infill seem to be a link between the fresh landforms of the SDB and the lacustrine sediment. Deposition in Lake Ulubat has been 1.60 cm a{sup -1} for the last 50 a according to radionuclides; however the sedimentation rate over the last millennium was 0.37 cm a{sup -1} based on {sup 14}C dating. The B content of the lacustrine infill displays a slight increase at 0.50 m and a drastic increase at 4 m depth occurring c. 31 a and c. 1070 a ago, respectively. Probably the topmost change corresponds to the start of open mining in the SDB and the second one to the natural trenching of borate ore-deposits. These dates also show indirectly a 1.4 cm a{sup -1} erosion rate during the last millennium as the borate beds were trenched up to 15 m. By extrapolation, it is possible to establish that the formation of some of the present morphological features of the southern Marmara region, especially river incision, began in the late Pleistocene, and developed especially over the last 75 ka.

    The mantle section of Guleman ophiolite, southeast (SE) Turkey consists mainly of harzburgites and dunite lenses and large chromitite pods. The average Cr ratio = [100 × Cr/(Cr + Al) atomic ratio] of Cr-spinels in harzburgites and dunites is remarkably high (>63). The forsterite (Fo) content of olivine is between 90.9 and 92.3 in harzburgites and dunites. These features indicate that the harzburgites and dunites resulted from >35% of partial melting of a depleted mantle source. Discriminant geochemical diagrams based on the mineral chemistry of harzburgites indicate a supra-subduction zone (SSZ) origin. Orthopyroxene and clinopyroxene from the Guleman harzburgites have low CaO, Al2O3 and TiO2 contents, resembling those of depleted harzburgites from modern forearcs and contrasting with moderately depleted abyssal peridotites. Consequently, we propose that the Guleman peridotites formed in a forearc setting during the subduction initiation that developed as a result of northward subduction of the southern branch of the Neo-Tethys in response to the convergence between the Arabian and Anatolian plates.

We examine the Toxocara seroprevalance in veterinarians and animal husbandry workers living in the Mugla Province, Turkey to evaluate better the risk factors for Toxocara exposure.Methods: In 2014, 376 volunteers participated in the study in 2014. All blood specimens were tested using a commercial enzyme immunoassay kit and ELISA positive samples were confirmed by Western Blot (WB method.Results: The seroprevalence of Toxocara, as determined by WB, was 8%. A statistically significant correlation was evident between patient age and Toxo­cara positivity among animal husbandry workers (P = 0.029. A strong associa­tion was also evident between sex and seropositivity in the animal husbandry group (P=0.024. Veterinarians working in pet clinics did in fact exhibit higher Toxocara seropositivities relative to those of other groups (P = 0.029. A statisti­cally significant difference was detected between the rural geographic areas surveyed (P = 0.04.Conclusion: In Mugla Province, seroprevalence of Toxocara is lower than other regions. Despite the low seroprevalence observed, especially in high risk professions toxocariasis remains an important medical concern within the region.

    Full Text Available As part of the International Continental Drilling Program (ICDP deep lake drilling project PaleoVan, we investigated sulfate reduction (SR in deep sediment cores of the saline, alkaline (salinity 21.4 ‰, alkalinity 155 m mEq-1, pH 9.81 Lake Van, Turkey. The cores were retrieved in the Northern Basin (NB and at Ahlat Ridge (AR and reached a maximum depth of 220 m. Additionally, 65-75 cm long gravity cores were taken at both sites. Sulfate reduction rates (SRR were low (≤ 22 nmol cm-3 d-1 compared to lakes with higher salinity and alkalinity, indicating that salinity and alkalinity are not limiting SR in Lake Van. Both sites differ significantly in rates and depth distribution of SR. In NB, SRR are up to 10 times higher than at AR. Sulfate reduction (SR could be detected down to 19 meters below lake floor (mblf at NB and down to 13 mblf at AR. Although SRR were lower at AR than at NB, organic matter (OM concentrations were higher. In contrast, dissolved OM in the pore water at AR contained more macromolecular OM and less low molecular weight OM. We thus suggest, that OM content alone cannot be used to infer microbial activity at Lake Van but that quality of OM has an important impact as well. These differences suggest that biogeochemical processes in lacustrine sediments are reacting very sensitively to small variations in geological, physical or chemical parameters over relatively short distances.

    Murder of women generally occurs as a result of violence by their husbands and relatives. We evaluated the female victims of murder in Eskişehir, located in western Anatolia, where the education level is high in this study. Our aim was to assess and discuss data related to the victims and murderers. A total of 141 women's murder cases were analysed in the study. After a legal process and the results of the autopsies during 2002-2011 in Eskişehir, 715 subjects found to have died as a result of murder were chosen. Cases were evaluated in terms of their age, marital status, education level, relationship to the murderer, reasons for violence, type of action and reasons for death. It was determined that 48.2% (n = 68) of the victims had been killed by the husband and 7.8% (n = 11) by the ex-husband. Murderers generally stated that the reason of murder was the woman's request for divorce or breaking up (n = 40, 28.4%). In compliance with the literature, the women were most commonly killed by their husbands in our study. Enhancing women's status and preventing violence against women will decrease such murders.

    The purpose of the study is to evaluate the seismic activity using the density analysis methods (point density and Kernel density analysis) for 2000-2015 earthquake catalogue belonging to the study area surrounded by Qanakkale to the north, Fethiye to the south and Denizli (Buharkent) to the east, and also to apply its correlation with geothermal regions. The earthquake data, in total 6.675 earthquakes with M>3 magnitudes were obtained from DDA Catalogue of Prime Ministry Disaster & Emergency Management Authority (AFAD) official website. In this survey, data analysis and maps were prepared using ArcGIS (version_10.1) program. The analysis maps present (1) the intensity clustered earthquakes dominant in Sigacik and Gokova Gulfs, (2) regions which have high seismic risk were determined according to Buffer analysis for 2 km distance, (3) geothermal areas (21.4-153°C) in the west coastal zone of Anatolia were mapped, (4) regions the most affected by seismic activity for the last 15 years were detected from 2015 population data, and as latest (5) Seferihisar, Urla, Gulbahge, Demircili, Bodrum, and Datga provinces are identified as areas having high seismic activity for the last 15 years. Consequently, all analysis results were compared with the geothermal areas, and the review made that earthquake catalogue has not the relationship with hot regions and also these shocks triggered by active faults in this region using ArcGIS program. the author recommends that these regions should be investigated the earthquake sensitivity analysis in the near future.

    Oil content and composition, biomass productivity and adaptability to different growth conditions are important parameters in selecting a suitable microalgal strain for biodiesel production. Here, we describe isolation and characterization of three green microalgal species from geothermal flora of Central Anatolia. All three isolates, namely, Scenedesmus sp. METUNERGY1402 (Scenedesmus sp. ME02), Hindakia tetrachotoma METUNERGY1403 (H. tetrachotoma ME03) and Micractinium sp. METUNERGY1405 (Micractinium sp. ME05) are adaptable to growth at a wide temperature range (25-50 °C). Micractinium sp. ME05, particularly has superior properties for biodiesel production. Biomass productivity, lipid content and lipid productivity of this isolate are 0.17 g L(-1) d(-1), 22.7% and 0.04 g L(-1) d(-1), respectively. In addition, Micractinium sp. ME05 and Scenedesmus sp. ME03 mainly contain desirable fatty acid methyl esters (i.e. 16:0, 16:1, 18:0 and 18:1) for biodiesel production. All isolates can further be improved via genetic and metabolic engineering strategies.

    Eastern wild turkeys (Meleagris gallopavo silvestris) (n = 1,023), obtained during winter, spring, and summer from 1983 to 1988 on Tallahala Wildlife Management Area (TWMA) (Jasper County, Mississippi, USA) were examined for avian pox lesions. Domestic turkey poults (n = 152) maintained on the area for 1 to 2 wk periods from 1987 to 1989 also were examined. Neither wild nor domestic birds showed gross evidence of pox virus infection. This study indicated that avian pox was not endemic in wild turkeys at TWMA.

    The aim of this study is to determine some hydro-physical and chemical characteristics of soils on the grassland areas under semi-arid conditions in terms of soil degradation processes. Three sampling plots of 20 × 20 m size were selected from the Emen Plain as Locations-I, II and III basing on the area covered with vegetation and visual soil properties; and total 108 soil samples from 2 points and 3 depth levels (0-20 cm, 20-40 cm, 40-60 cm) of each sampling plot. Soils of the research area are in degradation process in terms of some physical and chemical characteristics. It was observed that soil properties (i.e. bulk density, total porosity, organic matter, pH, electrical conductivity and saturated hydraulic conductivity) in Location-II and Location-III changed negatively in comparison to Location-I almost at all depths. In the Location-III grassland, bulk density, pH, electrical conductivity and Na + values are higher than those in Location-I, whereas the organic matter, total porosity and saturated hydraulic conductivity values are low. Grassland area is vulnerable to erosion. High Exchangeable Sodium Percentage (ESP) values in Locations-II and III indicates the sodicity problem in these areas.

    Hydro-climatic reconstructions from lake sediment proxies require an understanding of modern formation processes and calibration over multiple years. Here we use Nar Gölü, a non-outlet, monomictic maar lake in central Turkey, as a field site for such a natural experiment. Fieldwork since 1997 has included observations and measurements of lake water and sediment trap samples, and automated data logging (Jones et al., 2005; Woodbridge and Roberts, 2010; Dean et al., 2015). We compare these data to isotopic, chemical and biotic proxies preserved in the lake's annually-varved sediments. Nar Gölü underwent a 3 m lake-level fall between 2000 and 2010, and δ18O in both water and carbonates is correlated with this lake-level fall, responding to the change in water balance. Over the same period, sedimentary diatom assemblages responded via changes in habitat availability and mixing regime, while conductivity inferred from diatoms showed a rise in inferred salinity, although with a non-linear response to hydro-climatic forcing. There were also non-linear shifts in carbonate mineralogy and elemental chemistry. Building on the relationship between lake water balance and the sediment isotope record, we calibrated sedimentary δ18O against local meteorological records to derive a P/E drought index for central Anatolia. Application to of this to the longer sediment core isotope record from Nar Gölü (Jones et al. 2006) highlights major drought events over the last 600 years (Yiǧitbaşıoǧlu et al., 2015). Although this lacustrine record offers an archive of annually-dated, decadally-averaged hydro-climatic change, there were also times of non-linear lake response to climate. Robust reconstruction therefore requires understanding of physical processes as well as application of statistical correlations.

    In regions that are located in steep, orogenic plateau margins, such as the coastal area of the Central Anatolian Plateau (CAP) southern margin, natural hazard studies related to active tectonics and events that are triggered by active tectonics (e.g., earthquakes, landslides, tsunamis) are very essential in the context of preventing possible damages. This work herein, represents some evidence of the tsunami hazard along the coast between Aydıncık and Narlıkuyu, in southern Turkey. The work is based on a study on out-of-place beachrock-slab boulder acummulation in Aydıncık district, which were transported onshore by sliding process, and on out-of-place more rounded boulders that were transported by saltation process in Narlıkuyu and Yeşilovacık districts. The presence of intertidal organisms (e.g., lithophaga boring, balanids, oysters, etc.) encrusting the boulders of both localities shows that those boulders were carried onland from a marine environment. According to their dimensions and weight, in agreement with out-of-place boulders from areas surely affected by tsunamis, those out-of-place boulders here are interpreted as due to tsunami waves. The tsunamites in the Aydıncık area are located on beachrock slabs. They are platty and some of those blocks are embricated and oriented perpendicular to the shoreline (NE-SW direction). Those boulders have been interpreted as transported by sliding process, in relation with the coastal morphology and the boulder geometry, which means that to move those boulders the energy of the tsunami not necessarily should have been as high as in saltation or rolling transport processes. On the contrary, in Narlıkuyu and Yeşilovacık localities, the boulders are well-rounded and ellipsoidal shaped, suggesting that they were transported by rolling and/or saltation mode rather than by sliding. To carry onland the tsunami boulders observed in the Narlıkuyu and Yeşilovacık districts, which in the Yeşilovacık area they are

    Throughout human history, the region known today as the Anatolian peninsula (Turkey) has served as a junction connecting the Middle East, Europe and Central Asia, and, thus, has been subject to major population movements. The present study is undertaken to obtain information about the distribution of the existing mitochondrial D-loop sequence variations in the Turkish population of Anatolia. A few studies have previously reported mtDNA sequences in Turks. We attempted to extend these results by analysing a cohort that is not only larger, but also more representative of the Turkish population living in Anatolia. In order to obtain a descriptive picture for the phylogenetic distribution of the mitochondrial genome within Turkey, we analysed mitochondrial D-loop region sequence variations in 75 individuals from different parts of Anatolia by direct sequencing. Analysis of the two hypervariable segments within the noncoding region of the mitochondrial genome revealed the existence of 81 nucleotide mutations at 79 sites. The neighbour-joining tree of Kimura’s distance matrix has revealed the presence of six main clusters, of which H and U are the most common. The data obtained are also compared with several European and Turkic Central Asian populations.

    Dating of late Quaternary volcanism is crucial to understanding of the recent mechanism of crustal deformation and future volcanic explosivity risk of the region. However, radiometric dating of volcanic products has been a major challenge because of high methodological error rate. In most cases, there are difficulties on discrimination of the volcanic lava flow relations in the field. Furthermore, there would be unrecorded and unpreserved volcanoclastic layers by depositional and erosional processes. We present a new method that allows precise dating of late Quaternary volcanic events (in the time range of 0-500,000 years before present) using the Uranium-series technique on travertine mass, which is thought to be controlled by the young volcanism. Since the high pressure CO2 in the spring waters are mobilized during crustal strain cycles and the carbonates are precipitated in the fissures act as conduit for hot springs, thus, travertine deposits provide important information about crustal deformation. In this study we studied Ihlara fissure ridge travertines in the Central Anatolia Volcanic Province. This region is surrounded by many eruption centers (i.e. Hasandaǧı, Acıgöl and Göllüdaǧı) known as the late Quaternary and their widespread volcanoclastic products. Recent studies have suggested at least 11 events at around Acıgöl Caldera for the last 180 ka and 2 events at Hasandaǧı Stratovolcano for the last 30 ka. Active travertine masses around Ihlara deposited from hotwaters, which rise up through deep-penetrated fissures in volcanoclastic products of surrounding volcanoes. Analyses of the joint systems indicate that these vein structures are controlled by the crustal deformation due to young volcanism in the vicinity. Thus, the geological history of Ihlara travertine mass is regarded as a record of surrounding young volcanism. We dated 9 samples from 5 ridge-type travertine masses around Ihlara region. The age distribution indicates that the crustal

    The thermal structure of subduction zones plays a key role on mechanical and chemical processes taking place along the slab-mantle interface. Until now, changes through time of this thermal structure have been explored mostly by the means of numerical simulations. However, both "warm" (i.e., epidote-bearing), and "cold" (i.e., lawsonite-bearing) HP oceanic rocks have been reported in some fossil subduction complexes exposed at the Earth's surface (e.g., Franciscan Complex, California; Rio San Juan Complex, Hispañola; Halilbağı Unit, Central Anatolia). These a-priori "incompatible" rocks witness different thermal stages of ancient subduction zones and their study might provide complementary constraints to numerical models. To decipher the meaning of these contrasting metamorphic rocks in the Halilbağı Unit, we are carrying out Lu-Hf geochronology on garnet (grt) and lws from a variety of HP oceanic rocks, as well as the metamorphic sole of the overlying ophiolite. We selected five samples that are representative of the variety of metamorphic evolutions (i.e. peak conditions and P-T paths) encountered in this area. Preliminary analyses yielded 110 Ma (grt-hbl isochron) for a sub-ophiolitic grt amphibolite; 92 Ma (grt-omp) for an eclogite with prograde and retrograde ep; 90 Ma (grt-omp) for an eclogitic metabasite with prograde ep and retrograde ep+lws; 87 Ma (grt-gln) for a lws eclogite with prograde ep; and 86 Ma (grt-gln) for a blueschist with prograde and retrograde lws. These ages are mainly two-point isochrons. Further-refined data will be presented at the EGU General Assembly 2015, in Vienna. The consistent younging trend from "warm" to "cold" metamorphic rocks revealed by these first-order results points to metamorphic-sole formation during the initiation of intra-oceanic subduction at ~110 Ma, and subsequent cooling of the slab-mantle interface between 92 and 86 Ma. Therefore, the contrasting metamorphic evolutions encountered in the Halilbağı Unit

    The distribution of archaeomagnetic data in eastern Europe and the Near and Middle East shows a remarkable gap in Turkey. This study presents the first archaeomagnetic results from eight different archaeological sites in Central and Southeast Turkey. We sampled furnaces, burnt mud-brick walls, and granite and ignimbrite foundation stones. The rock magnetic experiments indicate that in the majority of the samples the dominant magnetic carrier is magnetite, which is stable to heating to temperatures of 700° C. In general, the demagnetization diagrams are single component and all sets display well-defined characteristic magnetizations and clustered directions. For the period between 2500 and 700 BCE, the declinations are between 350° and 20° while inclinations are in the range of 49-64° . The directional results are compared with the global geomagnetic field models (CALS7k.2, ARCH3k_cst.1 and CALS3k.4) and the data from the archaeomagnetic database GEOMAGIA50v2. The results are coherent with both the data and the models except for two near-contemporaneous sets dating ~2000 BCE, which are offset to the east by more than 20° with respect to CALS7k.2. Archaeointensity measurements were made using the microwave and conventional thermal Thellier methods, as well as the multi-specimen method. These different methods yielded comparable and intriguing results. While intensities from the furnaces are slightly higher than the CALS7k.2 model and in agreement with the GEOMAGIA50v2 and the Middle East data, the results from mud-brick walls suggest a high intensity of 100.8μT (17.7 x 1022 Am2 )at ~1000 BCE. This result is in excellent agreement with recent claims of extremely high intensity measured in other regions of the Middle East for this time period though less consistent with these being associated with extremely short-lived events. Finally, we discuss our new and other recently published archaeointensity results in terms of geomagnetic intensity versus climate.

    Full Text Available Information on turkey production and disease is rare in Nigeria, possibly because turkeys are seldom raised commercially. Also, turkeys require intensive husbandry and health care after hatching, which backyard poultry producers hardly provided especially, when raised in a disease endemic environment. In an attempt to document the diseases militating against turkey production in Nigeria, clinical and necropsy records were reviewed from veterinary practices in Jos and the Central Diagnostic Laboratory of the National Veterinary Research Institute (NVRI, Vom, Nigeria between 2009 - 2014. A total of 306 turkeys from backyard flocks were presented to the Veterinary clinics between 2009-2014 with various health complaints by backyard flock owners. Viral (Pox and Newcastle disease and parasitic (Helminthosis, Coccidiosis and Ectoparasitism diseases were mostly diagnosed. During the same period, 42 samples comprising 25 carcasses and 17 cloacal swabs were submitted for post mortem examination, virus isolation and microbiological test. Colisepticaemia, colibacillosis, pullorum disease, airsacculitis and infectious sinusitis are the main diseases diagnosed at post-mortem examination and microbiological test, while none of the samples were positive for influenza by virus isolation. It was observed that turkey rearing was small-scaled and kept as backyard poultry in North-central Nigeria. It can therefore be concluded from this study that turkeys raised in north-central city of Jos are affected by diseases ranging from viral to bacterial and parasitic, which can adversely affect productivity. This can therefore be improved upon by controlling the diseases mostly affecting turkeys.

The current taxonomic concept of D. turcicus is confirmed, and a lectotype is designated. Dilar turcicus is widely distributed in the southeast of Europe (being the only representative of Dilaridae in this region, in Anatolia, and, most probably, in the Caucasus region. Dilar syriacus and D. lineolatus remain nomina dubia. Dilar syriacus might occur in Anatolia, while D. lineolatus is a species occurring in western Central Asia. Two new species, Dilar anatolicus sp. n. and Dilar fuscus sp. n. are described from Anatolia. Wings and genital segments of the three species occurring in Anatolia are illustrated, and a map documenting the known distribution of these species is provided.

    The negative effects of non-renewable fossil fuels have forced scientists to draw attention to clean energy sources which are both environmentally more suitable and renewable. Although Turkey enjoys fairly high wind energy potential, an investigation and exploitation of this source is still below the desired level. In this study which is a preliminary study on wind energy cost in Central Anatolian-Turkey, the wind energy production using time-series approach and the economic evaluation of various wind energy conversion systems (WECSs) enjoying the 2.5, 5, 10, 20, 30, 50, 100 and 150 kW rated power size using the levelised cost of electricity (LCOE) method for the seven different locations in Central Turkey were estimated. In addition, effects of escalation ratio of operation and maintenance cost and annual mean speed on LCOE are taken into account. The wind speed data for a period between 2000 and 2006 years were taken from Turkish State Meteorological Service (TSMS). According to the result of the calculations, it is shown that the WECS of capacity 150 kW produce the energy output 120,978 kWh per year in the Case-A (Pinarbasi) for hub height 30 m and also the LCOE varies in the range of 0.29-30.0$/kWh for all WECS considered.

    The present study was conducted to better understand how the phylogenetic diversity of true morels (Morchella) in Turkey compares with species found in other regions of the world. The current research builds on our recently published surveys of 10 Turkish provinces and the northern hemisphere in which DNA sequence data from 247 and 562 collections respectively were analyzed phylogenetically. Herein we report on phylogenetic analyses of 243 additional collections made in spring 2009 and 2010 from eight additional provinces in the Aegean, Black Sea, central Anatolia, eastern Anatolia and Marmara regions of Turkey. Our analysis revealed that five species within the Esculenta clade (yellow morels) and 15 species within the Elata clade (black morels) were present in Turkey. Our preliminary results also indicate that M. anatolica, recently described from a collection in Muğla province in the Aegean region of Turkey, is a closely related sister of M. rufobrunnea; these two species comprise a separate evolutionary lineage from the Esculenta and Elata clades. Nine species of Morchella currently are known only from Turkey, four species were present in Turkey and other European countries and seven species might have been introduced to Turkey anthropogenically. Three of the putatively exotic species in Turkey appear to be endemic to western North America; they are nested within a clade of fire-adapted morels that dates to the late Oligocene, 25 000 000 y ago. Our results indicate that there are roughly twice as many Morchella species in Turkey compared with the other regions of Europe sampled. Knowledge of Morchella species diversity and their biogeographic distribution are crucial for formulating informed conservation policies directed at preventing species loss and ensuring that annual morel harvests are sustainable and ecologically sound.

    Full Text Available The deposition of Jurassic-Lower Cretaceous carbonates in the Pontides was controlled mainly by the evolution of an Atlantic-type continental margin in the Tethys. The study of several stratigraphic sections from allochthonous slices and blocks of the North Anatolian Ophiolitic Melange provided insight into the Middle Jurassic-Early Cretaceous paleogeographic evolution of the Central Pontide Belt. The Callovian-Aptian successions span the Globuligerina gr. oxfordiana, Clypeina jurassica (equivalent of the Tubiphytes morronensis zone, Protopeneroplis ultragranulata (with the Haplophragmoides joukowskyi subzone, Montsalevia salevensis, Hedbergella delrioensis - Hedbergella planispira - Leupoldina - Globigerinelloides and Globigerinelloides algerianus biozones. Two major stratigraphic gaps corresponding to the pre-Callovian and Hauterivian-Early Aptian ages are recognised within the successions. Lithostratigraphic and biostratigraphic studies indicate strong similarities in the evolution of the successions in the Amasya region (Central Pontides and Biga-Bursa-Bilecik (BBB Platform (North-western Anatolia

    Assessing vector-parasite relationship is important in understanding the emergence of vector-borne diseases and the evolution of parasite diversity. This study investigates avian Plasmodium parasites in mosquitoes collected from Kayseri province in Central Anatolian, Turkey and determines the haemosporidian parasite lineages from these mosquito species. A total of 6153 female mosquitos from 6 species were collected from 46 sites during June-August of 2008 and 2009. Each mosquito's head-thorax and abdomen were separated, categorized with respect to species and collection area and pooled for DNA extraction. A total of 1198 genomic DNA pools (599 thorax-head, 599 abdomen) were constituted of which 128 pools (59 thorax-head, 69 abdomen) were positive for avian haemosporidian parasites (Plasmodium and Haemoproteus) by Nested-PCR analysis. Culex pipens, Aedes vexans, Culex theileri and Culiseta annulata were positive with minimum infection rates (MIRs) of 16.22 and 18.15, 4.72 and 5.98, 5.18 and 10.36, 10.64 and 10.64 in their thorax-head and abdomen parts, respectively. No avian haemosporidian DNA was detected from Culex hortensis and Anopheles maculipennis. Phylogenetic analyses of the partial cytb gene of avian haemosporidian mt-DNA from 13 positive pools revealed that 11 lineages in four phylogenic groups were Plasmodium and the other two were Haemoproteus. Our results suggest that Cx. pipiens could probably be the major vector of avian Plasmodium in Central Turkey. This is the first report of molecular detection and characterization of avian Plasmodium lineages from mosquitoes in Turkey.

    Full Text Available Mushroom production that started in 1960's in Turkey gained economic value from the 1990's and it started improving as a commercial sector after that time. While Turkey mushroom production was 80 tons in 1973, it increased up to 45.000 tons in 2014. There is a rapid changes and improvement in cultivated mushroom production and consumption in Turkey. The object of the study is to reveal current status of mushroom production in the world and Turkey, and the problems of the mushroom sector in Turkey and the necessary precautions and ways to solve these problems. The data obtained from the inspections of the mushroom enterprises that in mushroom production regions of Turkey, and the secondary data obtained from Food and Agriculture Organization of the United Nations (FAO, Turkish Statistical Institute (TUIK and Union of Antalya Exporters (AIB and also national and international publication’ data has been used in this study. In Turkey, Mediterranean and Marmara Regions rank first in mushroom production and consumption with the share of 61.5 and 40%, respectively. It has been determined that big enterprises producing mushroom and compost established in the Central Anatolia in this study. The number of enterprises producing mushroom by using technology increases and 15-20% of the total production are provided by the big enterprises having 2000 m2 and over mushroom production areas. Recent years, there are serious increases in the production of different mushroom species such as especially Pleurotus ostreatus. In addition, precision agriculture applications are widespread with the time. For the continuation of growth of the mushroom sector in Turkey and the solving of the sector problems, there are needs both in making the necessary changes in legislation and to be given priority researches related to mushroom production in university and public research institutions and also to support them.

    The United Nations Children's Fund (UNICEF) defines child poverty as the inability of the child to realize their existing potential due to their inability to access resources across different dimensions of life (income, health, nutrition, education, environment, etc.). On the basis of this definition, an attempt has been made in this study to put forth the disadvantaged positions children have in different dimensions of their lives, specifically by taking regional disparities into account. As the data source, the Turkey Demographic and Health Survey 2008 is used, a survey that consists of detailed information about the different dimensions of child poverty. In this study, in order to measure poverty in four different dimensions (education and work, health and nutrition, family environment, and domestic environment), a total of 25 variables were used and descriptive and multivariate analyses were made in order to highlight the regional disparities in child poverty. Principle components analysis conducted through the use of a deficit approach reveals that the variables closely related with education and health and nutrition were the critical dimensions behind child poverty in Turkey. The results of this study indicate that 22.4% of children in Turkey are poor when various dimensions of life are taken into account; the region with the highest child poverty is Central East Anatolia, at 34.9%, while the region with the lowest rate is East Marmara, at 15.6%.

    Full Text Available Using the space-time distribution of 1162 uniformly recalibrated dates from 71 sites in Asia Minor, the Aegean Basin, Southern Thrace and Macedonia, this article presents geostatistical (kriging and graphical simulations of the Neolithic expansion out of Anatolia. How fast was the advance of the agricultural pioneer front? Did it proceed in a single wave, moving at a steady pace, or did it involve instead long periods of stasis, punctuated by rapid advances? The article suggests that the expansion was more arrhythmic than linear. The spread of farming halted in Central Anatolia for several hundred years, before quickly expanding into Europe.

    The Miocene volcanic rocks along the İzmir-Balıkesir Transfer Zone along the western margin of the Menderes Core Complex (MCC) in western Anatolian Volcanic Province (WAVP), where strike-slip deformation is dominant, comprise: (Group 1) early-middle Miocene high-K to shoshonitic rocks with high-Mg# and relatively low SiO2, (Group 2) middle Miocene phonolitic rocks with low-Mg# and intermediate SiO2, (Group 3) early-middle Miocene medium- to high-K series from andesites to rhyolites, (Group 4) middle Miocene rhyolites with distinct trace element compositions; and (Group 5) late Miocene high-MgO basalts, K-trachybasalts and (Group 6) late Miocene high-MgO basaltic andesites. The geochemical features of these rocks are comparable with the other Oligocene to Miocene volcanic rocks, but differ from the Eocene volcanic rocks in WAVP. The geochemical features of the most primitive early-middle Miocene Group 1 rocks indicate that they were derived from an anomalously metasomatized lithospheric mantle. The mineralogical and geochemical properties of garnet-amphibole peridotite from the Ulten Zone (UZP), Eastern Alps, which is thought to represent a fossil metasomatic mantle wedge contaminated by continental subduction, is similar to the model mantle composition previously proposed for the genesis of the mafic rocks. Together with the presence of Eocene to early Miocene continental subduction beneath the Aegean-west Anatolia region, this strongly suggests that continental subduction was an important factor in the genesis of the high-MgO shoshonitic to ultrapotassic volcanism in this post-collisional area. The origin of the Group 3 andesitic to rhyolitic rocks includes; (1) lower crustal melting, (2) mixing between lower crustally-derived and mantle-derived melts, and (3) FC-AFC processes. The late Miocene Group 5 and 6 rocks, however, derived from a more depleted mantle source, indicating that the mantle became depleted over time. The rhyolites of Group 4 are most probably

    2014-12-01

    Full Text Available The German art historian Friedrich Sarre (1865-1945 is best known as the director, from 1925-31, of the Islamic collection of the Berlin Museums, and for his collaboration with Ernst Herzfeld on the excavation of the Abbasid palaces of Samarra, Iraq, just before the onset of the 1914-18 war. From a historiographical point of view, however, Sarre also deserves attention for his work on the Seljuk architecture of Anatolia, a subject that had been barely studied within the context of Islamic art when he ventured into it. Crucially, Sarre’s study of Seljuk architecture is rooted in the late nineteenth-century appreciation of Persian art, rather in the later focus on a unified Turkish identity that became pervasive in the late 1920s, following ideological shifts after the foundation of the Republic of Turkey.

    On 29 June 1170 a large earthquake hit a vast area in the Near Eastern Mediterranean, comprising the present-day territories of western Syria, central southern Turkey, and Lebanon. Although this was one of the strongest seismic events ever to hit Syria, so far no in-depth or specific studies have been available. Furthermore, the seismological literature (from 1979 until 2000) only elaborated a partial summary of it, mainly based solely on Arabic sources. The major effects area was very partial, making the derived seismic parameters unreliable. This earthquake is in actual fact one of the most highly documented events of the medieval Mediterranean. This is due to both the particular historical period in which it had occurred (between the second and the third Crusades) and the presence of the Latin states in the territory of Syria. Some 50 historical sources, written in eight different languages, have been analyzed: Latin (major contributions), Arabic, Syriac, Armenian, Greek, Hebrew, Vulgar French, and Italian. A critical analysis of this extraordinary body of historical information has allowed us to obtain data on the effects of the earthquake at 29 locations, 16 of which were unknown in the previous scientific literature. As regards the seismic dynamics, this study has set itself the question of whether there was just one or more than one strong earthquake. In the former case, the parameters (Me 7.7 ± 0.22, epicenter, and fault length 126.2 km) were calculated. Some hypotheses are outlined concerning the seismogenic zones involved.

    Full Text Available The use of rootstocks particularly for sweet cherry cultivars is of great importance for successful and sustainable production. Choosing the right cherry rootstocks is just as important as choosing the right cultivar. In this study, 110 sweet cherry, 30 sour cherry, and 41 mahaleb types displaying rootstock potential for sweet cherry cultivars were selected from Central and East Black Sea Regions in Turkey. The morphologic characteristics of the studied genotypes were compared with the standard clonal rootstocks PHL-A, MaxMa 14, Montmorency, Weiroot 158, Gisela 5, Gisela 6, and SL 64. A total of 42 morphological UPOV characteristics were evaluated in the selected genotypes and clonal rootstocks. The obtained data were analyzed by using principal component analysis and it revealed that eigenvalues of the first 3 components were able to represent 36.43% of total variance. The most significant positive correlations of the plant vigor were determined with leaf blade length and petiole thickness. According to the diversity analysis of coefficients, the 05 C 002 and 08 C 039 genotypes were identified as being similar (6.66, while the 05 C 002 and 55 S 012 genotypes were determined as the most distant genotypes (325.84 in terms of morphology.

    EMRE ÜNAL

    2003-07-01

    Full Text Available The best preserved Permian-Triassic boundary beds in Turkey are found in the Hadim region of the central Taurides. The succession is exposed in one of the allochthonous units of the Tauride Belt, the Aladag Unit, whose stratigraphy includes beds ranging from the Devonian to the Cretaceous systems. In the Aladag Unit, the Permian-Triassic boundary beds are entirely composed of carbonates. The Permian portion of these beds belongs to the Paradagmarita Zone, whereas the lowermost Triassic contains the Lower Griesbachian marker Rectocornuspira kalhori. The uppermost Permian carbonates, composed of meter-scale upward shallowing subtidal cycles, are characterized by oolitic limestones of regressive character at the top and are overlain sharply by Lower Triassic stromatolites. Cyclic Upper Permian carbonates are interpreted as highstand sytems tract deposits of the last third-order sequence of the Permian System. The Permian-Triassic boundary is an unconformity corresponding to both erosional and non-depositional hiatuses. The gap at the Permian-Triassic boundary partially corresponds to the shelf-margin systems tract and partly to the transgressive systems tract of the overlying third-order sequence. Stromatolites are interpreted as transgressive systems tract deposits. Special issueInternational Conference on Paleozoic Foraminifera, Paleoforams 2001Edited by Demir Altiner (Guest Editor

  14. Source parameters of the 2005-2008 Balâ-Sırapınar (central Turkey) earthquakes: Implications for the internal deformation of the Anatolian plate

    2014-11-01

    Active tectonics of central Anatolia is mainly governed by the collision of the African, Arabian and Anatolian plates, which causes westward escape of Anatolia along the North and East Anatolian Fault zones, and the counterclockwise rotation of the Kırşehir block with insignificant internal deformation. The formation of the present-day tectonic processes in this region can be deduced from geophysical prospecting and seismological data. Although the seismicity in central Anatolia is distinctively lower than that in the northern and eastern parts of the Anatolian plate, small and moderate earthquakes (2.5 ≤ Mw ≤ 6.0) mostly occurred in the region in the past decades or so. For example, intense earthquake activity was observed in the Balâ-Afşar-Sırapınar (Ankara, central Anatolia) region in the period of 2005 to 2008 with destructive earthquakes of July 30, 2005 (Mw = 5.2); December 20, 2007 (Mw = 5.7) and December 26, 2007 (Mw = 5.6). Therefore, these earthquakes are crucial to analyze the shallow crustal deformation in the central Anatolian block. In the present study, we obtained source parameters of 2005-2008 earthquake sequence using the regional moment tensor (RMT) inversion method. We analyzed complete broad-band waveforms recorded at near-field distances (0.45° ≤ Δ ≤ 3.6°). Our results reveal NW-SE directed right-lateral strike-slip faulting and NE-SW directed left-lateral strike-slip faulting mechanisms, which are clearly correlated with the conjugate fault systems in the Balâ-Afşar-Sırapınar region. However, some earthquakes also have E-W directed normal faulting components. We suggest that the major characteristics of 2005-2006 and 2007-2008 earthquake activity could have been dominantly associated with left-lateral and right-lateral strike-slip faulting mechanisms, respectively. The seismogenic depth is found to be about 8-10 km. This result implies that earthquakes in the study region occurred mostly in the upper crust, which

    In the northern part of the Central Pontides (N Turkey) there are different metamorphic rocks exposed, notably the Devrekani metamorphic rocks. Here, upper amphibolite-lower granulite facies metamorphic rocks contain predominantly paragneiss, orthogneiss and metacarbonate, and to a lesser extent, amphibolite and quartzite, with cross-cutting aplite, pegmatite and granite veins. This is the first report of these rocks and includes new data on the petrochemistry, geochronology and metamorphic evolution of the Devrekani orthogneisses from the Central Pontides. The orthogneisses show five different mineral parageneses with the characteristic mineral assemblage quartz + K-feldspar + plagioclase + biotite ± hornblende ± opaque (± ilmenite and ± magnetite), and accessory minerals (zircon, sphene and apatite). These metamorphic rocks exhibit generally granoblastic, lepidogranoblastic and nematolepidogranoblastic with locally migmatitic and relic micrographic textures. They have well-developed centimeter-spaced gneissic banding and display gneissose structure with symmetric, asymmetric and irregular folds. The petrographic features, mineralogical assemblages and weak migmatization reflect high temperature conditions. Thermometric calculations in the orthogneisses indicate metamorphic temperatures reached 744 ± 33 °C. Field relations, petrography and petrochemistry suggest that the orthogneisses have predominantly granodioritic and some granitic protoliths, that show features of I-type, medium to high-potassic calc-alkaline volcanic arc granitoids. The orthogneisses have high contents of LILEs and low contents of HFSEs with negative Nb and Ti anomalies, which are typical of subduction-related magmas. The orthogneisses also show significant LREE enrichment relative to HREE with negative Eu anomalies (EuN/Eu* = 0.33-1.07) with LaN/LuN = 6.98-20.47 values. Based on U-Pb zircon dating data, the protoliths are related to Permo-Carboniferous (316-252 Ma) magmatism. It is

    2016-11-01

    Full Text Available In our country, there are many cheese types that are produced traditionally. Cheeses which produced from cows, sheep and goat milk that matured with spontaneous growth of molds present in livestock skins, pots and similar environments are among them. They are produced traditionally in Mediterrian, Central and Eastern Anatolia regions. Molds that grow spontaneously in cheeses could create public health risk because of their secondary metabolites. Penicillium spp. are the most isolated mold from these cheeses and Penicillium roqueforti is determined as the dominant species. Furthermore, Aspergillus, Alternaria, Mucor, Geotrichum, Cladosporium species have been isolated. It is very important to control the ripening conditions and starter strain selection since some strains were reported as mycotoxin producers. In this review, it has been tried to give general information about traditional production of mold-ripened cheese in Turkey and the mold flora found in traditional cheeses. In addition, public health risk of these cheeses is reported.

    The Sivas Basin in the Central Anatolian Plateau (Turkey), which formed in the context of a foreland fold-and-thrust belt (FTB), exhibits a typical wall and basin (WAB) province characterized by symmetric minibasins separated by continuous steep-flanked walls and diapirs. Extensive fieldwork including regional and detailed local mapping of the contacts and margins of minibasins, and interpretation of a set of 2-D regional seismic lines, provide evidence for the development of a shallow evaporite level separating two generations of minibasins within the WAB province. Here beds of symmetric exposed minibasins along diapir flank are younger than minibasins observed over autochthonous evaporites. Laterally away from the WAB province, increase in wavelength of the tectonic structures suggests a deepening of the decollement level. We interpret that a shallower evaporite level developed in the form of an evaporite canopy, triggered by significant lateral shortening. The Upper Eocene-Lower Oligocene autochthonous Tuzhisar evaporite level was remobilized by the northward migrating sedimentary load and the tilting of the southern basin margin during propagation of the foreland fold-and-thrust belt. Asymmetric and symmetric primary minibasins were overrun by an allochthonous sheet forming a canopy. A second generation of salt withdrawal minibasins subsided into the allochthonous salt sheet. The polygonal pattern of the WAB province influences the growing fold-and-thrust belt system during the late stage of the secondary minibasins development. The Sivas FTB basin is the result of the interaction between fold-and-thrust belt propagation, evaporite remobilization, and interaction between evaporite flow and sedimentation in the minibasins.

    2014-01-01

    Full Text Available Results of a crustal heat flow analysis in western Anatolia based on borehole equilibrium temperatures and rock thermal conductivity data are reported. The dataset comprises 113 borehole sites that were collected in Southern Marmara and Aegean regions of Turkey in 1995–1999. The measurements are from abandoned water wells with depths of 100–150 m. Data were first classed in terms of quality, and the low quality data, including data showing effects of hydrologic disturbances on temperatures, were eliminated. For the remaining 34 sites, one meter resolution temperature-depth curves were carefully analyzed for determination of the background geothermal gradients, and any effects of terrain topography and intra-borehole fluid flow were corrected when necessary. Thermal conductivities were determined either by direct measurements on representative surface outcrop or estimated from the borehole lithologic records. The calculated heat flow values are 85–90 mW m−2 in the northern and central parts of the Menderes horst-graben system. Within the system, the highest heat flow values (> 100 mW m−2 are observed in the northeastern part of Gediz Graben, near Kula active volcanic center. The calculated heat flow values are also in agreement with the results of studies on the maximum depth of seismicity in the region. In the Menderes horst-graben system, surface heat flow is expected to show significant variations as a result of active sedimentation and thermal refraction in grabens, and active erosion on horst detachment zones. High heat flow values (90–100 mW m−2 are also observed in the peninsular (western part of Çanakkale province. The heat flow anomaly here may be an extension of the high heat flow zone previously observed in the northern Aegean Sea. Moderate heat flow values (60–70 mW m−2 are observed in eastern part of Çanakkale and central part of Balıkesir provinces.

    ERCAN ÖZCAN

    2001-03-01

    Full Text Available Lepidorbitoides bisambergensis is characterised by having a ‘quadriserial’ embryo without any chamberlet directly arising from the deuteroconch and is a very diagnostic and common species in Lower Maastrichtian flysch successions in Anatolia. Some populations of this species present an early ontogenetic morphologic feature which is characterised by distinctly asymmetric early chamber arrangement recognised in the horizontal sections. This asymmetry is mainly caused by the pronounced difference in the size of auxiliary chamberlets which rest on both, protoconch and deuteroconch and also enhanced by the development of unequal number of chamberlets in the series arising from these auxiliary chamberlets on the protoconchal side. These asymmetric specimens are commonly identified in stratigraphic horizons below the symmetric ones after the introduction of a new auxiliary chamberlet and progressively replaced by symmetric ones in the younger populations. Asymmetric "quadriserial" specimens representing the early phylogenetic stage of L. bisambergensis described in the stratigraphic horizons corresponding to G. havanensis and G. aegyptiaca (? zones are thought to deserve a particular taxonomic status and are attributed to Lepidorbitoides bisambergensis asymmetrica Özcan & Özkan-Altiner, 1999a.

    2016-07-01

    In the Kayıköy area of Isparta-Gölcük district, Inner Isparta Angle, SW Anatolia, Turkey, a small volume of newly discovered K-rich mafic potassic magma was emplaced in the form of dome in the vicinity of graben structures under Pliocene (3.68 ± 0.5 Ma) extensional tectonics. Kayıköy leucite ankaratrites are made up of abundant diopside, barian phlogopite and leucite, and lesser olivine, that rarely contains Cr-spinel, nepheline and haüyne, with abundant magnetite. They have low SiO2 (44.00-46.04 wt.%) and Al2O3 (12.10-12.64 wt.%) with high K2O (4.00-4.42 wt.%), CaO (13.50-14.40 wt.%) and MgO (8.52-9.36 wt.%), with high Cr (397-547 ppm) and moderate Ni (57-74 ppm) contents. They represent the less evolved silica-undersaturated mafic potassic magmas within the Isparta-Gölcük volcanic province, and may be considered another parental source to the wide spectrum of the K-rich rocks. They are highly enriched in most of the incompatible elements (e.g., Ba, 2761 to > 10,000 ppm; Sr, 3700-4074 ppm; Th, 33.60-36.99 ppm; Zr, 274-321 ppm) with high LREEs, low HREEs and elevated LREEs/HREEs ratios [(La/Yb)N, 73-80] and are comparable with kamafugite and carbonatites. Trace element patterns have negative P, Ti and Nb-Ta anomalies in common with the Italian kamafugite province and lack of a Eu anomaly, in contrast to the negative Eu anomaly of the Italian province. Their Sr87/86-Nd143/144 (0.703877-0.512765) isotopic compositions, together with those of other potassic volcanics from the Inner Isparta Angle, coincide with the West Quinling (China) kamafugites with highly depleted mantle signatures, and young East African carbonatites. Olivine-Cr-spinel pairs, high Mg# (0.69-0.73) numbers and Cr values, and high incompatible and LREE contents in Kayıköy leucite ankaratritic magma are consistent with near-primary magmas equilibrated with enriched and heterogeneous (peridotitic/pyroxenitic) mantle sources. On the basis of (i) their geochemical signatures [low Ti

    Full Text Available Turkey has made in the last 4 decades a remarkable growth in economy. The energy industry is represented mainly by the coal industry (especially lignite and coal, located in northwest Anatolia. The electricity is produced in the hydro and thermal power plants. Turkey has the world's 17th largest nominal GDP, and 15th largest GDP by PPP. The country is a founding member of the OECD (1961 and the G-20 major economies (1999. Since December 31, 1995, Turkey is also a part of the EU Customs Union. While many economies have been unable to recover from the recent global financial recession, the Turkish economy expanded by 9.2% in 2010, and 8.5 percent in 2011, thus standing out as the fastest growing economy in Europe, and one of the fastest growing economies in the world. Hence, Turkey has been meeting the “60 percent EU Maastricht criteria” for public debt stock since 2004. Similarly, from 2002 to 2011, the budget deficit decreased from more than 10 percent to less than 3 percent, which is one of the EU Maastricht criteria for the budget balance. As of 2012, the main trading partners of Turkey are Germany, Russia and Iran. Turkey has taken advantage of a customs union with the European Union, signed in 1995, to increase industrial production for exports, while benefiting from EU – origin foreign investment into the country. Turkey is also a source of foreign direct invest-ment in central and eastern Europe and the CIS, with more than $1.5 billion invested. 32% has been invested in Russia, primarily in the natural resources and construction sector, and 46% in Turkey’s Black Sea neighbours, Bulgaria and Romania. Turkish companies also have sizable FDI stocks in Poland, at about $100 million. The construction and contracting companies have been significant players, such as Enka, Tekfen, Gama, and Üçgen İnşaat, as well as the three industrial groups, Anadolu Efes Group, ŞişeCam Group and Vestel Group. The exports reached $115.3 billion in

    Enzootic bovine leukosis (EBL) which is caused by bovine leukaemia virus (BLV) has an important economic impact on dairy herds due to reduced milk production and restrictions on livestock exports. This study was conducted to determine the BLV infection status in Central Anatolia Region of Turkey, an important milk production centre, and to examine the risk factors such as purchasing cattle, increasing cattle age, cattle breed and herd size associated with transmission of BLV infection. To estimate the rate of BLV infection, a survey for specific antibodies in 28,982 serum samples from animals belonging to 1116 different herds situated in Central Anatolia Region of Turkey were tested from January 2006 to December 2013. A generalized mixed linear model was used to evaluate the risk factors that influenced BLV seroprevalence. Antibodies against BLV were detected in 431 (2.28 %) of 18,822 Holstein and 29 (0.28 %) of 10,160 Brown Swiss cows. Among 1116 herds, 132 herds (11.82 %) had one or more positive animals. Also results of our study show that the prevalence of BLV infection increased from 2006 to 2011, and it tends to reduce with BLV control programme. Furthermore, we found positive associations between percentage of seropositive animal and increasing cattle age, herd size, cattle breed and purchased cattle. Age-specific prevalence showed that BLV prevalence increased with age. These factors should be taken into consideration for control of BLV infection.

    Along the Mediterranean coastal area of southern Anatolia, markers of ancient sea-level have been reported west of Alanya and east of the Göksu delta. In both areas, bioconstructed fossil rims, consisting mainly of calcareous algae, are situated 0.5 m above the live counterpart. The fossil rim to the west of Alanya has been dated between 2690 to 1545 yrs BP, evidencing late Holocene rock uplift at the CAP southern margin. More recently, based on beachrocks along the coastal area from Incekum to the south of Adana, authors showed that the shoreline was raised around 0.5 m after 19 BC-200 AD. Based on new field observations along the coast between Aydı ncı k and Ayaş (Mersin, southern Turkey), together with AMS 14C dating and high-resolution U-Th chronology, a more complex uplift history can be suggested. Along the coast of Yeşilovacı k, we observed up to seven uplifted marine notches, from 0.5 m to 6.10 m above sea level. Some of them show relationships with a travertine crust that yielded U-Th ages of 2727 ± 1559 years and 5236 ± 2255 years. In the same area, a calcareous algae fossil trottoir related to a marine notch 5.40 m above sea level yielded an AMS 14C 2σ age of 32700 to 31645 years cal BP. Considering that the global ocean was 60 m below the present sea level at 32 ka, the Yeşilovacı k coastal area has been uplifted at 2 mm/yr. Moving to the east, in a small embayment at Eǧribük, two distinct well cemented beach deposits containing Murex brandaris, Cerithium vulgatum, and Columbella rustica have been uplifted at 0.3 m and 0.7 m above the present sea level. Although it is difficult to reconstruct the paleodepth of those beach deposits, AMS 14C 2σ ages of 5575 to 5445 years cal BP and 2130 to 1965 years cal BP show late Holocene uplift. In the Narlı kuyu area, up to seven different uplifted markers of sea level were observed between 0.8 and 7.2 m above the present sea level. In addition, near Ayaş new insights for late Holocene uplift are

    Turkey has important chromite, magnesite and olivine deposits within peridotite host rocks. The peridotites (harzburgite, verlite, lherzolite and dunite) are mostly serpentinised as a result of metasomatic reaction of olivine and pyroxene minerals with percolating water. The serpentinites are generally an important part of ophiolitic complexes which displays a discontinuous belts all over the country. The chromite deposits are often related to cumulates and tectonites (as Alpine and/or podiform type deposits) and despite their small reserves, their grade can reach up to 58 %. In most deposits, a little enrichment efforts, the grade of chromite can easily be reached from 25 % to 40-45 %. The magnesite deposits of West Anatolia is especially concentrated in three provinces. These provinces are Konya, Kutahya and Eskisehir. The magnesites are of cryptocrystalline type and, like chromite deposits, their reserve are small but have high grade with low FeO-CaO and high MgO ratio. Once again, these deposits are found within serpentinised peridotites of ultramafic belts. The total (proven and inferred) magnesite reserves are approximately 200 million tons, and these are mostly cryptocrystalline character. A small amount of sedimentary magnesite deposits also present in Denizli (SW Anatolia) and Erzincan (Eastern Anatolia). The olivine deposits are found within peridotites of Western Anatolia. Especially, the Kızıldag olivine deposits (located between the border of Antalya and Konya provinces) are noteworthy with its huge (9 billion tons) reserves. The main olivine mineral is forsterite (Mg2SiO4) which has economically important when compared to other olivine mineral fayalite. The deposits have no quality problem but have a serious disadvantages since its location far from the ports and railway stations.

    Full Text Available The Atatürk Dam is the fourth largest clay-cored rock fill dam in the world. It was constructed on the Euphrates River located in semi-arid Southeastern Turkey in the 1980s as the central component of a large-scale regional development project for the Southeastern Anatolia region (referred to as GAP. The construction began in 1983 and was completed in 1990. The dam and the hydroelectric power plant, which went into service after filling up the reservoir was accomplished in 1992. The Atatürk Dam, which has a height of 169 m, a total storage capacity of 48.7 million m3, and a surface area of about 817 km2 plays an important role in the development of Turkey's energy and agriculture sectors. In this study, the spatial and temporal impacts of the Atatürk Dam on agro-meteorological aspects of the Southeastern Anatolia region have been investigated. Change detection and environmental impacts due to water-reserve changes in Atatürk Dam Lake have been determined and evaluated using multi-temporal Landsat satellite imageries and meteorological datasets within a period of 1984 to 2011. These time series have been evaluated for three time periods. Dam construction period constitutes the first part of the study. Land cover/use changes especially on agricultural fields under the Atatürk Dam Lake and its vicinity have been identified between the periods of 1984 to 1992. The second period comprises the 10-year period after the completion of filling up the reservoir in 1992. At this period, Landsat and meteorological time-series analyses are examined to assess the impact of the Atatürk Dam Lake on selected irrigated agricultural areas. For the last 9-year period from 2002 to 2011, the relationships between seasonal water-reserve changes and irrigated plains under changing climatic factors primarily driving vegetation activity (monthly, seasonal, and annual fluctuations of rainfall rate, air temperature, humidity on the watershed have been investigated

    The aim of this study was to determine the radon concentrations in the water supplies of a residential area of central west Anatolia, Turkey. This research provides a preliminary risk assessment for inhabitants in the study area which can be applied for other regions. In 14 out of the 19 water supplies analysed, radon concentrations exceeded the maximum contaminant level (11.1 Bq l(-1)). The total annual effective doses of 10 for the wet season and 14 for the dry season out of the 19 water supplies are greater than the values recommended by EPA [Cancer Risk Coefficients for Environmental Exposure to Radionuclides, Federal Guidance Report No. 13 (US Environmental Protection Agency, Washington, DC, 1999) pdf >] (0.1 mSv a(-1)). The elevated radon concentrations in water resources are most probably linked with geological origin which contains significant amounts of radioactive minerals.

    The purpose of this study is to revaluate the changing spatial and temporal trends of precipitation in Turkey. Turkey is located in one of the regions at greatest risk from the potential effects of climate change. Since the 1970s, a decreasing trend in annual precipitation has been observed, in addition to an increasing number of precipitation-related natural hazards such as floods, extreme precipitation, and droughts. An understanding of the temporal and spatial characteristics of precipitation is therefore crucial to hazard management as well as planning and managing water resources, which depend heavily on precipitation. The ordinary kriging method was employed to interpolate precipitation estimates using precipitation records from 228 meteorological stations across the country for the period 1976-2010. A decreasing trend was observed across the Central Anatolian region, except for 1996-2000 which saw an increase in precipitation. However, this same period is identified as the driest year in Eastern and South Eastern Anatolia. The Eastern Black Sea region has the highest precipitation in the country; after 1996, an increase in annual precipitation in this region is observed. An overall reduction is also seen in southwest Turkey, with less variation in precipitation.

  14. Signature of slab fragmentation beneath Anatolia from full-waveform tomography

    When oceanic basins close after a long period of convergence and subduction, continental collision and mountain building is a common consequence. Slab segmentation is expected to have been relatively common just prior to closure of other oceans in the geological past, and may explain some of the complexity that geologists have documented in the Tibetan plateau also. We focus on the eastern Mediterranean basin, which is the last remainder of a once hemispherical neo-Tethys ocean that has nearly disappeared due to convergence of the India and Africa/Arabia plates with the Eurasia plate. We present new results of full-waveform tomography that allow us to image both the crust and upper mantle in great detail. We show that a major discontinuity exists between western Anatolia lithosphere and the region to the east of it. Also, the correlation of geological features and the crustal velocities is substantially stronger in the west than in the east. We interpret these observations as the imprint in the overriding plate of fragmentation of the neo-Tethys slab below it. This north-dipping slab may have fragmented following the Eocene (about 35 million years ago) arrival of a continental promontory (Central Anatolian Core Complex) at the subduction contact. From the Eocene through the Miocene, slab roll-back ensued in the Aegean and west Anatolia, while the Cyprus-Bitlis slab subducted horizontally beneath central and east Anatolia. Following collision of Arabia (about 16 million years ago), the Cyprus-Bitlis slab steepened, exposing the crust of central and east Anatolia to high temperature, and resulting in the velocity structure that we image today. Slab fragmentation thus was a major driver of the evolution of the overriding plate as collision unfolded.

    The continental collision between Arabia and Eurasia created large strike-slip faults in Turkey as well as mountains in the Caucasus and the volcanic plateau between them. In this study, we use regional waveforms of a new seismic array deployed between 2008 and 2012 to constrain the focal mechanisms and depths of small to moderate sized earthquakes occurring in the western part of the Central Caucasus and northeast Turkey. The distribution of aftershocks and the twelve focal mechanisms involved in the sequence of the 2009 earthquake in Racha are clearly a reactivation of a deeper segment of the 1991 M7 Racha rupture zone. The deeper segment is not well connected to the shallower décollement separating the basement and sedimentary basin. The earthquakes we determined in northeastern Turkey and southern Georgia are related to the strike-slip fault system. We further combined all of the reliably determined focal mechanisms over the last 30 years to investigate the current stress status of the crust in three areas: Racha in the western Greater Caucasus, Javakheti near the Lesser Caucasus and in Northeast Turkey. Our results show that the directions of maximum compressional stress consistently fall within - 2 to 14°N throughout the entire study region. This appears to be controlled by the continental collision. Nonetheless, the minimum compression switches from vertical (in the Greater Caucasus) to the east-west direction (in northeastern Turkey), due to the westward extrusion of the Anatolia block, which is driven partly by the Hellenic subduction. The transition of the stress field is close to the Javakheti volcanic plateau in the Lesser Caucasus, where the relative magnitude between the principal stresses appears to be strongly variable.

    Full Text Available In this study, the influence of an extraordinary Saharan dust episode over Turkey on 23–24 March 2016 and the atmospheric conditions that triggered this event were evaluated in detail. PM10 (particulate matter less than 10 μm observations from 97 air quality stations, METAR (Meteorological Terminal Aviation Routine Weather Report observations at 64 airports, atmospheric soundings, and satellite products were used for the analysis. To determine the surface and upper levels of atmospheric circulation, National Centers of Environmental Prediction (NCEP/National Center for Atmospheric Research (NCAR Reanalysis data were applied to the extreme dust episodes. On 23 March 2016, high southwesterly winds due to the interaction between surface low- and high-pressure centers over Italy and Levant basin brought thick dust particles from Libya to Turkey. The daily PM10 data from 43 stations exceeded their long-term spring means over Turkey (especially at the northern and western stations. As a consequence of the longitudinal movement of the surface low from Italy to the Balkan Peninsula, and the quasi-stationary conditions of the surface high-pressure center allowed for the penetration of strong south and southwesterly winds to inner parts of the country on the following day. As a consequence, 100%, 90%, 88%, and 87% of the monitoring stations in Marmara (NW Turkey, central Anatolia, western (Aegean and northern (Black Sea regions of Turkey, respectively, exhibited above-normal daily PM10 values. In addition, while strong subsidence at the low levels of the atmosphere plays a significant role in having excessive daily PM10 values in Black Sea, dry atmospheric conditions and thick inversion level near the ground surface of Marmara ensured this region to have peak PM10 values ~00 Local Time (LT.

    Tularemia is a zoonotic disease caused by Francisella tularensis. Sporadic tularemia cases have been increasingly reported particularly from provinces located at northwest and central regions of Turkey especially during last two decades, as well as waterborne outbreaks reported from almost all regions. Transmission most often occurs through consumption of contaminated water and food, thus, oropharyngeal form is the most common clinical presentation in our country. The aim of this study was to present a small outbreak experience in Afsin, country of Kahramanmaras province located at southern part of Turkey. A total of 10 patients (5 male, 5 female; age range 2-68 years; mean age 25 years) who were admitted to Afsin State Hospital with the complaints of swollen neck between 21 October 2013-22 January 2014, were evaluated considering their clinical findings and treatment outcomes. Following the diagnosis of the first tularemia case coming from Nadir village, a field investigation was performed. All villagers were informed about the disease and water samples from the possible sources of outbreak were collected by provincial health authorities. Lymph node aspirate and serum samples were sent for culture and serologic investigation and the environmental water samples were sent for molecular analysis to the National Tularemia Reference Laboratory at Public Health Institution of Turkey. Six out of 10 patients' sera were found positive in terms of F.tularensis antibodies between the titers of 1/320-1/1280 by microagglutination test (MAT) and diagnosis of oropharyngeal tularemia was based on the clinical and serological findings. One of the patients also presented with oculoglandular form accompanying oropharyngeal form. Cultures from aspirate samples that could be obtained from only two patients yielded negative results. Three out of six patients' lymph nodes were drained surgically and one was drained by ultrasound-guided needle. In one case lymph node suppuration occured

    Full Text Available The Hocaköy section measured from the Alakirçay Nappe (middle nappe of the Antalya Nappes contain rich radiolarian fauna ranging from late Norian (Late Triassic to middle-late Cenomanian (mid Cretaceous. At the basal part of the section, the Late Triassic (late Norian-Rhaetian Gökdere Formation is characterized by gray to beige cherty limestone at the base and pinkish red chert- gray to beige limestone alternation at the top, with moderately to well-preserved radiolarians in the red chert beds. The overlying Jurassic - Middle Cretaceous Hocaköy Radiolarite is mainly represented by chert-mudstone alternations with some limestone interlayers. Radiolarians of the Gökdere Formation can be well correlated with that of the fauna from the Mino Terrane, central Japan and the fauna from the Queen Charlotte Islands, British Columbia, Canada. Four radiolarian zones from central Japan are recognized in the fauna obtained from Gökdere Formation such as “Praemesosaturnalis multidentatus Lowest Occurrence Zone (TR8A” (late Norian, “Praemesosaturnalis pseudokahleri Lowest Occurrence Zone (TR8B” (late Norian, ? “ Skirt F lowest Occurrence Zone (TR8C” (late Norian-Rhaetian and partly “Haeckelicyrtium breviora Taxon Range Zone (TR8D” (Rhaetian.

    The Menderes Massif (western Turkey) is an important metamorphic core complex located in the Aegean region; geochemical and geochronological data from this extensional domain facilitates our understanding of large-scale extension of the Earth's lithosphere. S-type, peraluminous granites (Salihli and Turgutlu) that intrude the Alasehir detachment which bounds the northern edge of the central Menderes Massif may have been generated due to subduction of the Eastern Mediterranean floor along the Hellenic trench. In situ Th-Pb ion microprobe monazite ages from the granites range from 21.7±4.5 Ma to 9.6±1.6 Ma (±1s). The range is consistent with cathodoluminescence (CL) imagery that document complex textures within the samples. Salihli and Turgutlu granites share many similar characteristics, including multiple generations of plagioclase (some with shocked cores consistent with magma mixing), plagioclase replacing K-feldspar and the development of myrmekite, clear evidence for fluid infiltration, and multiple generations of microcracks and microfaults. The granites may have evolved from compositionally distinct magma sources, as Salihli samples in general contain allanite as the major accessory mineral, whereas Turgutlu granites contain monazite. However, the CL imagery document similar alteration textures. Ages reported here are similar to dates constraining extension reported elsewhere in the Aegean, but indicate a level of complexity when linking movement within the Menderes Massif to the large-scale geodynamic processes that created other metamorphic core complexes in the region. Difficulties exist in linking the ages obtained from the granites to specific tectonic events due to the presence of secondary alteration textures, generations of mineral growth, and multiple episodes of deformation.

    The study area comprises southern non-metamorphic part of the Bolkar Mountains which are situated in southern Turkey, eastern part of the Central Taurides. The studied five outcrops form geologically parts of the tectonostratigraphic units called as allochthonous Aladag Unit and autochthonous Geyikdagi Unit. The aim of this study is to describe microfacies and depositional environments of the Bolkar Mountains Early Cretaceous shallow- water platform carbonates. The Lower Cretaceous is represented by continuous thick- bedded to massive dolomite sequence ranging from 100 to 150 meters thick, which only contains locally laminated limestone intercalations in the Yüğlük section and thick to very thick-bedded uniform limestones ranging from approximately 50 to 120 meters, consist of mainly laminated- fenestral mudstone, peloidal-intraclastic grainstone-packstone, bioclastic packstone- wackestone, benthic foraminiferal-intraclastic grainstone-packstone, ostracod-fenestral wackestone-mudstone, dasycladacean algal packstone-wackestone and ooidal grainstone microfacies. Based on a combination sedimantological data, facies/microfacies and micropaleontological (predominantly dasycladacean algae and diverse benthic foraminifera) analysis, it is concluded that Early Cretaceous platform carbonates of the Bolkar Mountains reflect a tidally affected tidal-flat and restricted lagoon settings. During the Berriasian- Valanginian unfavourable facies for benthic foraminifera and dolomitization were predominate. In the Hauterivian-early Aptian, the effect of dolomitization largely disappeared and inner platform conditions still prevailed showing alternations of peritidal and lagoon facies, going from peritidal plains (representing various sub-environments including supratidal, intertidal area, tidal-intertidal ponds and ooid bars) dominated by ostracod and miliolids, to dasycladacean algae-rich restricted lagoons-subtidal. These environments show a transition in the vertical and

    East Anatolia is a region of high topography made up of a 2-km high plateau and Neogene and Quaternary volcanics overlying the subduction-accretion complex formed by the process of collision. The aeromagnetic and gravity data surveyed by the Mineral Research and Exploration (MTA) of Turkey have been used to interpret qualitatively the characteristics of the near-surface geology of the region. The residual aeromagnetic data were low-pass filtered and analyzed to produce the estimates of magnetic bottom using the centroid method and by forward modelling of spectra to evaluate the uncertainties in such estimates. The magnetic bottom estimates can be indicative of temperatures in the crust because magnetic minerals lose their spontaneous magnetization at the Curie temperature of the dominant magnetic minerals in the rocks and, thus, also are called Curie point depths (CPDs). The Curie point depths over the region of Eastern Anatolia vary from 12.9 to 22.6 km. Depths computed from forward modelling of spectra with 200 600 km window sizes suggest that the bottom depths from East Anatolia from the magnetic data may have errors exceeding 5 km; however, most of the obtained depths appear to lie in the above range and indicate that the lower crust is either demagnetized or non-magnetic. In the interpretation of the magnetic map, we also used reduction-to-pole (RTP) and amplitude of total gradient of high-pass filtered anomalies, which reduced dipolar orientation effects of induced aeromagnetic anomalies. However, the features of the RTP and the total gradient of the high-pass filtered aeromagnetic anomalies are not highly correlated to the hot spring water locations. On the other hand, many high-amplitude features seen on the total gradient map can be correlated with the ophiolitic rocks observed on the surface. This interpretation is supported by Bouguer gravity data. In this paper, we recommend that the sources of the widespread thermal activity seen in East Anatolia must

    Anatolia played an important role in the diversification and spread of economically important Vitis vinifera varieties. Although several biodiversity studies have been conducted with local cultivars in different regions of Anatolia, our aim is to gain a better knowledge on the biodiversity of endangered historical V. vinifera varieties in the northern Adana region of southern Anatolia, particularly those potentially displaying viticulture characteristics. We also demonstrate the genetic relatedness in a selected subset of widely cultivated and commercialized V. vinifera collection cultivars, which were obtained from the National Grapevine Germplasm located at the Institute of Viticulture, Turkey. In the present study, microsatellites were used in narrowing the sample size from 72 accessions down to a collection of 27 varieties. Amplified fragment length polymorphisms were then employed to determine genetic relatedness among this collection and local V. vinifera cultivars. The unweighted pair group method with arithmetic mean cluster and principal component analyses revealed that Saimbeyli local cultivars form a distinct group, which is distantly related to a selected subset of V. vinifera collection varieties from all over Turkey. To our knowledge, this is the first study conducted with these cultivars. Further preservation and use of these potential viticultural varieties will be helpful to avoid genetic erosion and to promote continued agriculture in the region.

    Poverty, a complex, multidimensional, and universal problem, has been conceptualized as income and material deprivation. In this article, we discuss poverty and related factors in Turkey. The absolute poverty line for Turkey was US$ 4 per capita per day. Turkey was ranked 92nd out of 177 countries with moderate human development in the 2006 Human Development Report. The individual food poverty rate was 1.35% and the non-food poverty rate was 25.6%. The highest poverty rate was among primary school graduates (42.5%; 38.5% for women and 46.8% for men). The rate for this group was higher in urban than in rural areas. Among poor people, 57.2% were married. The highest poverty rate was among agricultural workers (46.6%) and in Eastern and Southeastern Anatolia. Factors related to poverty were crowded households, unemployment, immigration, working for a daily wage in the agricultural and construction sector, low educational status, female sex or married status, lacking social insurance, and living in rural areas or in Eastern and Southeastern Anatolia.

The research group consisted of 6061 adolescents. With an age average of 15.53 years. The Inventory of Attachment to Parents and Friends- Brief Form (EABE was used as data acquisition tool. The results of the study indicated significant difference between the scores of students regarding the inventory of attachment to parents according to regions. Evaluating the findings regarding attachment to father and mother together, the findings were similar, and the attachment levels of adolescents in Middle Anatolia, Eastern Anatolia and Black Sea Region were found to be higher than the ones in other regions. This result may be related with socioeconomic, geographical and cultural structures of the regions. Examining the finding according to gender variable, the scores of male students are significantly lower than the scores of female students. As a result according to the data gained from a wide sample group; the main factors for the attachment of adolescents to their parents in Turkey are the geographical regions in Turkey and the gender.

    Full Text Available The venom of poisonous snakes comprises a complex mixture of several proteins with other less significant constituents, resulting in principles capable of changing viable tissues. The hemotoxic factor is the main responsible for necrosis and tissue sloughing. Envenomations are common in rural areas of Turkey caused by snake species that present hepatotoxic venom, which causes local swelling, ecchymosis and alterations in blood profile. The epidemiological and clinical findings of snake envenomations in Turkey were evaluated based on data recorded by the National Poison Information Center (NPIC between 1995 and 2004, in a total of 550 snakebite cases. The month of peak incidence was June (24.3% while most incidents occurred in Marmara, Central Anatolia and Black Sea regions of Turkey. The victims were mainly adults (54.1%. Hospitalized patients displayed clinical signs of local (75.2% and systemic effects (24.7%. Local clinical symptoms comprised edema, pain, hyperemia, numbness and ecchymosis, while systemic clinical symptoms included nausea, vomiting, hypotension, tachycardia, dyspnea, dry mouth, paresthesia, generalized edema, cyanosis and compartment syndrome. Occasionally, convulsions, confusion, loss of consciousness, hyperthermia, hepatic and circulation failure, hematoma, drowsiness, epistaxis, chest and abdominal pain, venous spasm, thrombocytopenia and bradycardia were recorded. Approximately one third (34.2% of the patients were treated symptomatically, while 10.5% required antivenom therapy along with symptomatic treatments and 26.3% of all patients were exclusively treated with antivenom. Although a significant number of incidents were reported, no deaths occurred. These findings emphasize the presence of multiple medically important snake species in Turkey and that public awareness and therapeutic approaches appear sufficient to manage snakebite incidents.

    The (late syn)- post-collisional magmatic activities of western and northwestern Anatolia are characterized by intrusion of a great number of granitoids. Amongst them, Baklan Granite, located in the southern part of the Muratdağı Region from the Menderes Massif (Banaz, Uşak), has peculiar chemical and isotopic characteristics. The Baklan rocks are made up by K-feldspar, plagioclase, quartz, biotite and hornblende, with accessory apatite, titanite and magnetite, and include mafic microgranular enclaves (MME). Chemically, the Baklan intrusion is of sub-alkaline character, belongs to the high-K, calc-alkaline series and displays features of I-type affinity. It is typically metaluminous to mildly peraluminous, and classified predominantly as granodiorite in composition. The spider and REE patterns show that the rocks are fractionated and have small negative Eu anomalies (Eu/Eu ∗ = 0.62-0.86), with the depletion of Nb, Ti, P and, to a lesser extent, Ba and Sr. The pluton was dated by the K-Ar method on the whole-rock, yielded ages between 17.8 ± 0.7 and 19.4 ± 0.9 Ma (Early Miocene). The intrusion possesses primitive low initial 87Sr/ 86Sr ratios (0.70331-0.70452) and negative ɛNd(t) values (-5.0 to -5.6). The chemical contrast between evolved Baklan rocks (SiO 2, 62-71 wt.%; Cr, 7-27 ppm; Ni, 5-11 ppm; Mg#, 45-51) and more primitive clinopyroxene-bearing monzonitic enclaves (SiO 2, 54-59 wt.%; Cr, 20-310 ppm; Ni, 10-70 ppm; Mg#, 50-61) signifies that there is no co-genetic link between host granite and enclaves. The chemical and isotopic characteristics of the Baklan intrusion argue for an important role of a juvenile component, such as underplated mantle-derived basalt, in the generation of the granitoids. Crustal contamination has not contributed significantly to their origin. However, with respect to those of the Baklan intrusion, the generation of the (late syn)- post-collisional intrusions with higher Nd(t) values from the western Anatolia require a much

    Objective:To classify and characterize spider bites among inquiries to the National Poison Information Center (NPIC) between1995 and2004, in terms of the epidemiology and clinical symptomatology.Methods: Clinical and epidemiological data were obtained from theNPIC’s patient records. The following information was recorded for each spider bite: demographics, circumstances of the bite, and local and systemic effects.Results: A total of82 cases were reported. The accidents were mostly seen during August. The gender distribution was59.76%male, 37.20% female, and2.44% unknown and the20-29 age group presented more spider bites. Most of the cases were in the Central Anatolia, Marmara, Mediterranean, and Black Sea regions. Local symptoms were observed in60.87% of the cases, including local pain, edema, redness, itching, debris, burning, and numbness. Systemic symptoms were observed such as nausea, vomiting, abdominal pain, lethargy, anxiety, weakness, somnolence, dyspnea, hypertension, hypotension, and hyperthermia.Conclusions: In conclusion, these findings emphasize the presence of medically important spider species in Turkey. All patients and especially pediatric patients should be admitted to the hospital. Identification of spider species may be considered a useful clinical and epidemiological tool in determining the incidence and risk of spider bites.

  11. Tibet and Beyond: Magmatic Records from CIA (Caucasus-Iran-Anatolia) and Southern Tibet with Implications for Asian Orogeny and Continental Growth

    This study, based on an ongoing joint research project "Tibet and Beyond", presents a synthesis of principal magmatic records from the CIA (Caucasus-Iran-Anatolia) and Tibet-Himalaya orogens resulting from the continental collisions of Arabia and India, respectively, with Eurasia. In both orogens, through this and other recent studies, the temporal and spatial variations in magmatism pre-, syn- and post-dating the collisions can now be much better defined, thus improving our understanding of collision zone magmatism that appears to have evolved with changes in the lithospheric structures over time and space by collisional processes. The two "collisional" Tethyan orogens were preceded by accretionary orogenic processes, which not only had produced a substantial amount of juvenile continental crust but also fulfill the "orogenic cycle" that evolved from an accretionary into a collisional system. Geochemical data reveal that in contrast to generating vast portions of juvenile crust in the early, accretionary stages of orogenic development, crustal recycling plays a more important role in the later, collisional stages. The latter, as exemplified in SE Turkey and southern Tibet, involves addition of older continental crust material back into the mantle, which subsequently melted and caused compositional transformation of the juvenile crust produced in the accretionary stages. Similar features are observed in young volcanic rocks from eastern Taiwan, the northern Luzon arc complex and part of the active subduction/accretion/collision system in Southeast Asia that may evolve one day to resemble the eastern Tethyan and central Asian orogenic belts by collision with the advancing Australian continent.

    The Konya Closed Basin (KCB) located in Central Anatolia, Turkey, is the primary grain producer in Turkey. The lack of sufficient surface water resources and recently changing crop patterns have led to over-exploitation of groundwater resources and resulted in significant drop in groundwater levels. For this reason monitoring of the groundwater storage change in this region is critical to understand the potential of the current water resources and to devise effective water management strategies to avoid further depletion of the groundwater resources. Therefore, the main objective of this study is to examine and assess the utility of the Gravity Recovery and Climate Experiment (GRACE) and the Global Land Data Assimilation System (GLDAS) to monitor and investigate the groundwater storage changes in the Konya Closed Basin. Groundwater storage changes are derived using GRACE and GLDAS data and then are compared with the groundwater changes derived from the observed groundwater levels. The initial results of the comparison indicate an acceptable agreement between declining trends in GRACE-based and observed groundwater storage change during the study time period (2002 to 2015). Additionally, the results indicated that the study region exhibited remarkable drought conditions during 2007-2008 period. This study shows that the GRACE/GLDAS datasets can be used to monitor the equivalent groundwater storage changes which is crucial for long-term effective water management strategies.

    This paper focuses mainly on the coastline change assessment on water reservoirs located in the Konya Basin Area, Turkey. The Konya Closed Basin exists at the Central Anatolia Region and covers a region of 50,000 km(2) area corresponding to the 7% cumulative area of Turkey in which three million people live, 45% in rural areas and 55% in urban areas. The basin is surrounded with the city centers of Konya, Aksaray, Karaman, Isparta, Niğde, Ankara, Nevşehir, and Antalya cities. In this study, these changes were examined using Landsat TM and ETM+ 1987-2006 and 1990-2000. In the image processing step, image and vectorization of the satellite images were carried out to monitor coastline changes over the lakes located in the Konya Closed Basin Area. At the end of the study, significant coastline movements were detected for a 19-year period due to drought effects, agricultural watering, and planning mistakes experienced in the basin.

    Eastern Anatolia is characterized by 2 km plateau uplift -in the last 10 Myrs-, high surface heat flow distribution, shallow Curie-point depth, anomalous gravity field. Seismological observations indicate relatively high Pn and Sn attenuation and significant low seismic velocity anomalies in the region. Moreover, the surface geology is associated predominantly with volcanic rocks in which melt production through mantle upwelling (following lithospheric delamination) has been suggested. It has been long known that the topographic loading in the region cannot be supported by crustal thickness (~45 km) based on the principle of Airy isostasy. Recent global geodynamic studies carried out for evaluating the post-collisional processes imply that there is an explicit dynamic uplift in Eastern Anatolia and its adjacent regions. In this study we investigate the instantaneous dynamic topography driven by 3-D upper-mantle flow in Eastern Anatolia. For this purpose we conducted numerous thermo-mechanical models using a 2-D Arbitrary Lagrangian Eulerian (ALE) finite element method. The available P-wave tomography data extracted along 10 profiles were used to obtain depth-dependent density anomalies in the region. We present resulting dynamic topography maps and estimated 3D mantle flow velocity vectors along these 2-D cross sections for each profile. The residual topography based on crustal thickness and observed topography was calculated and compared with other independent datasets concerning geological deformation and dynamic topography predictions. The results indicate an upper mantle driven dynamic uplift correlated with the under-compensated characteristic in Eastern Anatolia. We discuss our results combined with 3D mantle flow by considering seismic anisotropy studies in the region. Initial results indicate that high dynamic uplift and the localized low Pn velocities in concurrence with Pn anisotropy structures show nearly spatial coherence in Eastern Anatolia.

    Full Text Available International Continental Scientific Drilling Program (ICDP drilled a complete succession of the lacustrine sediment sequence deposited during the last ~500,000 years in Lake Van, Eastern Anatolia (Turkey. Based on a detailed seismic site survey, two sites at a water depth of up to 360 m were drilled in summer 2010, and cores were retrieved from sub-lake-floor depths of 140 m (Northern Basin and 220 m (Ahlat Ridge. To obtain a complete sedimentary section, the two sites were multiple-cored in order to investigate the paleoclimate history of a sensitive semi-arid region between theBlack, Caspian, and Mediterranean seas. Further scientific goals of the PALEOVAN project are the reconstruction of earthquake activity, as well as the temporal, spatial, and compositional evolution of volcanism as reflected in the deposition of tephra layers. The sediments host organic matter from different sources and hence composition, which will be unravelled using biomarkers. Pathways for migration of continental and mantle-derived noble gases will be analyzed in pore waters. Preliminary 40Ar/39Ar single crystal dating of tephra layers and pollen analyses suggest that the AhlatRidge record encompasses more than half a million years of paleoclimate and volcanic/geodynamic history, providing the longest continental record in the entire Near East to date.

    Occupational fatalities and work-related injuries are more common in Turkey than in most developing and developed countries. Several precautions have been taken concerning the matter, and The Occupational Health and Safety Act (OHSL 2012) has been passed. These efforts, however, have failed to incorporate in their framework the role of global warming. New legislation is underway for the prevention of occupational diseases, injuries, and fatalities. This is particularly worrisome given that Turkey is in the forefront of countries projected to be affected seriously by climate change. Consequently, a study on the direct and indirect impact of climate change on workers' health and labour productivity is paramount. The main purpose of this research is to present diminishing labour productivity as a consequence of decreased working hours via an estimate of rest hours of workers in manual labour. The climatic outputs of Regional Climate Model (RegCM3) obtained from the ENSEMBLES Project are used to calculate the wet bulb globe temperature (WBGT) over western Turkey. The study covers the span of years between 1971 and 2100. Moreover, spatial distributions of observed domain are estimated by means of a seasonal analysis, preliminary to a more detailed research. Critical regions, more adversely influenced than others, are identified. The total number of loss days for these critical regions are presented for various time periods. As a result, labour productivity particularly in agriculture and construction is expected to diminish seriously over Central Anatolia, Cyprus, and parts of the Aegean and eastern Mediterranean coastal areas. Between 2071 and 2100, deficiency in labour productivity may reach up to 52 % during the summer across some of these critical regions. Though it will be seen that the present study has focused primarily on manual labour and outdoor work in particular, it foreshadows nevertheless the dangerous impact of climate change on occupational health and

    It is important that health personnel have extensive and adequate knowledge and practice regarding forensic evidence. This article describes the knowledge and practices of health personnel, who work in emergency rooms and health centers, regarding forensic evidence. The health personnel in a city in Central Anatolia, Turkey, constitute the population of this descriptive study and 233 personnel constitute its sample. It was determined that 31.3% stated that the practices of forensic evidence collection are inadequate. It was determined that average knowledge scores of health personnel with respect to forensic evidence are 23.5 ± 7.28 of 40. It was found that there was a statistically significant difference between knowledge scores on the subject of forensic with respect to duty (p = 0.005), level of education (p = 0.005), and institution of health personnel (p = 0.015). It was determined that the scores of the health personnel, who work in emergency services and health centers, on the subject of forensic evidence, are not at a desirable level.

    The recent discovery of Oligo-Miocene salt-walled continental mini-basins in the Sivas Basin (central Anatolia, Turkey) provides the opportunity to unravel the influence of halokinesis on the diagenesis of continental mini-basin infilling. In this study, petrographic and geochemical analyses are used to define the diagenetic sequences recorded by two mini-basins filled mainly by fluvial clastic sediments of the upper Oligocene Karayün Formation. The initial diagenetic features are those commonly encountered in arid to semi-arid continental environments, i.e. clay infiltration, hematite precipitation and vadose calcite cement. Other early cements were strongly controlled by sandstone detrital composition in the presence of saline/alkaline pore water. In feldspathic litharenites and lithic arkoses, near-surface alterations were characterized by the precipitation of analcime (up to 10%), albite and quartz overgrowths (burial diagenesis which prevented further mesogenetic alteration phenomena such as compaction. In feldsarenites, early diagenesis differs by (i) the absence of analcime, (ii) better developed albite cements, (iii) thin smectite-illite coatings forming pore linings and (iv) patchy calcite cementation (burial, and result in a significant degradation of porosity.

    The North Anatolian fault (NAF) is a ???1500 km long, arcuate, dextral strike-slip fault zone in northern Turkey that extends from the Karliova triple junction to the Aegean Sea. East of Bolu, the fault zone exhibits evidence of a sequence of large (Mw >7) earthquakes that occurred during the twentieth century that displayed a migrating earthquake sequence from east to west. Prolonged human occupation in this region provides an extensive, but not exhaustive, historical record of large earthquakes prior to the twentieth century that covers much of the last 2000 yr. In this study, we extend our knowledge of rupture events in the region by evaluating the stratigraphy and chronology of sediments exposed in a paleoseismic trench across a splay of the NAF at Destek, ???6:5 km east of Lake Ladik (40.868?? N, 36.121?? E). The trenched fault strand forms an uphill-facing scarp and associated sediment trap below a small catchment area. The trench exposed a narrow fault zone that has juxtaposed a sequence of weakly defined paleosols interbedded with colluvium against highly fractured bedrock. We mapped magnetic susceptibility variations on the trench walls and found evidence for multiple visually unrecognized colluvial wedges. This technique was also used to constrain a predominantly dip-slip style of displacement on this fault splay. Sediments exposed in the trench were dated using both charcoal and terrestrial gastropod shells to constrain the timing of the earthquake events. While the gastropod shells consistently yielded 14 C ages that were too old (by ???900 yr), we obtained highly reliable 14 C ages from the charcoal by dating multiple components of the sample material. Our radiocarbon chronology constrains the timing of seven large earthquakes over the past 3000 yr prior to the 1943 Tosya earthquake, including event ages of (2?? error): A.D. 1437-1788, A.D. 1034-1321, A.D. 549-719, A.D. 17-585 (1-3 events), 35 B.C.-A.D. 28, 700-392 B.C., 912-596 B.C.

    The east Anatolian orogenic plateau is characterized by an average elevation of 2 km, and is delimited by the Bitlis-Zagros collision zone to the south and the Pontide arc to the north. Stratigraphic evidence suggests that the high plateau attained its current elevation since the Serravallian (about 12 million years ago), but probably did not reach its present height until at least the latest Pliocene. While the crustal shortening following the Arabia-Eurasia collision in the south enabled its relatively rapid rise and regional tectonic evolution, the presumed removal of the downgoing slab beneath east Anatolia has potentially played a significant role in this geodynamic configuration. According to the proposed scenario, the northward subducting slab of Neo-Tethys peels away from the overlying crust similar to the lithospheric delamination model. In this work, we performed a series of lithospheric removal models by varying rheological, physical and mechanical properties by using 2D numerical geodynamic experiments, (e.g. plate convergence rate, crustal thickness, mantle lithosphere yield-stress). Our model results show that the average amount of delamination hinge motion is maximum (18 km/my) when the lower crustal rheology is felsic granulite. The slab break-off only occurs at lower convergence rates (≤ 2 cm/yr), and is imposed on the margin of delaminating mantle lithosphere. The surface uplift takes place above the asthenospheric column (or plateau gap) through isostatic and thermal support of asthenospheric upwelling, and varies dependent on the width of the asthenospheric column. However; with higher plate convergence rates (≥3 cm/yr), the asthenospheric column does not widen enough and the continental collision occurs rather than delamination/peeling away. In this case, the average uplift appears in the central section of the crust, and this exceeds a surface elevation of 3 km. All model results are consistent with the observations from the Eastern

    Radiometric calibration is critical to ensure the accuracy, veracity, continuity and reliability of satellite data measured from multiple sensors and platforms, and is thus recognized as a key activity by all satellite operators. For imaging sensors, vicarious methods using natural targets (such as salt lakes, deserts, or flatlands that are well-characterized and preferably temporally and spatially stable) as a reference are similarly well established. However, while selecting a target site, it is important that its quality and location are selected to minimize sources of uncertainty for any given sensor. To maximize the benefit from limited resources and minimize the impact on satellite operators, the Infrared Visible Optical Sensor (IVOS) sub-group of Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV) has selected a few, well-characterized, regularly instrumented target sites, which have since become known as LANDNET sites. Currently, there are eight LANDNET sites: 1) Dome C, Antarctica; 2) Dunhuang, China, Asia; 3) Lspec Frenchman Flat, NV, USA, North America; 4) Ivanpah, NV/CA, USA, North America; 5) La Crau, France, Europe; 6) Negev, Southern Israel, Asia; 7) Railroad Valley Playa, NV, USA, North America; 8) Tuz Gölü, Central Anatolia, Turkey, Asia. This work summarizes the key characteristics, and areas of application of each of the LANDNET sites, especially that of Tuz Gölü, to guide and inform researchers on site selection, and increase international awareness and collaboration in this field. Additionally, detailed information about the Tuz Gölü, Turkey test site is provided, including geographical characteristics, spatial uniformity qualities, and opportunities for international researchers to conduct experiments and measurements. Practical, technical, and logistical experience gained through the international field campaigns organized over the last few years at Tuz Gölü is also shared in detail.

  7. Analyzing Turkey's data from TIMSS 2007 to investigate regional disparities in eighth grade science achievement

    Turkey is expected to be a full member of the European Union (EU) by 2013. In the course of its integration into the EU, Turkey has been simultaneously facing access, quality, and equity issues in education. Over the past decade, substantial progress has been made on increasing the access. However, improving the country's low level of education quality and achieving equity in quality education across the regions continue to be a monumental challenge in Turkey. Most recently, results from the Trends in International Mathematics and Science Study (TIMSS) 2007 indicated that Turkey's educational achievement at the eighth grade, the end of compulsory primary education in Turkey, was far below that of other countries in the EU. Considering Turkey's long standing socioeconomic disparities between the western and eastern parts of the country, the challenges of improving overall education quality are coupled with the challenges of achieving equity in learning outcomes for students across the regions. This dissertation used data from TIMSS 2007 to document the extent of Turkey's regional differences in science achievement at the eighth grade and to investigate factors associated with these differences. Findings from a series of analyses using hierarchical linear models suggested that attempts to increase Turkish students' achievement and close the achievement gaps between regions should target the students in the undeveloped regions, particularly in Southeastern Anatolia and Eastern Anatolia. Designing interventions to improve competency in Turkish and to compensate for the shortcomings of insufficient parental education, limited home educational resources, poor school climate for academic achievement, and inadequate instructional equipment and facilities might be expected to close the regional achievement gaps as well as raise the overall achievement level in Turkey.

  8. MIDDLE JURASSIC-LOWER CRETACEOUS BIOSTRATIGRAPHY IN THE CENTRAL PONTIDES (TURKEY): REMARKS ON PALEOGEOGRAPHY AND TECTONIC EVOLUTION

    The deposition of Jurassic-Lower Cretaceous carbonates in the Pontides was controlled mainly by the evolution of an Atlantic-type continental margin in the Tethys. The study of several stratigraphic sections from allochthonous slices and blocks of the North Anatolian Ophiolitic Melange provided insight into the Middle Jurassic-Early Cretaceous paleogeographic evolution of the Central Pontide Belt. The Callovian-Aptian successions span the Globuligerina gr. oxfordiana, Clypeina jurassica (equi...

  9. Extensional and compressional regime driven left-lateral shear in southwestern Anatolia (eastern Mediterranean): The Burdur-Fethiye Shear Zone

    The tectonic framework of the eastern Mediterranean presented in this paper is based on an active subduction and small underwater hills/mountains on the oceanic crust moving toward the north. The Hellenic Arc, the Anaximander Mountains, the Rhodes and Finike basins, the compressional southern regions of the Western Taurides, and the extensional western Anatolian graben are the main interrelated tectonic structures that are shaped by the complex tectonic regimes. There are still heated debates regarding the structural properties and tectonic evolution of the southwestern Anatolia. GPS velocities and focal mechanisms of earthquakes demonstrate the absence of a single transform fault across the Burdur-Fethiye region; however, hundreds of small faults showing normal and left-lateral oblique slip indicate the presence of a regionally extensive shear zone in southwestern Turkey, which plays an important role in the eastern Mediterranean tectonics. The 300-km-long, 75-90-km-wide NE-SW-trending Burdur-Fethiye Shear Zone developed during the formation of Aegean back-arc extensional system and the thrusting of Western Taurides. Today, the left-lateral differential motion across the Burdur-Fethiye Shear Zone varies from 3 to 4 mm/yr in the north to 8-10 mm/yr in the south. This finding could be attributed to the fact that while the subduction of the African Plate is relatively fast beneath the western Anatolia at the Hellenic Trench, it is slow or locked beneath the Western Taurides. Therefore, the GPS vectors and their distributions on land indicate remarkable velocity differences and enable us to determine the left-lateral shear zone located between the extensional and compressional blocks. Furthermore, this active tectonic regime creates differences in topography. This study also demonstrates how deep structures, such as the continuation of the subduction transform edge propagator (STEP) fault between the Hellenic and Cyprus arcs in the continental area, can come into play

    This study describes the frequency of mole guns in Turkey by examining the cases sent to the Council of Forensic Medicine of Turkey between 2003 and 2005. In total, 11 mole guns were examined. Mole guns are manufactured to be used as a trap against detrimental animals. Although they are not meant to be used as a firearm, they are able to cause death. Mole guns appearing in regular casework were evaluated in terms of type of the gun, number of barrels, size and caliber, rifling, design, mechanism, fitness for use, legality, and geographical distribution. Ninety-one percent of the guns were 12 gauge. Most commonly they originate from Inner Anatolia. Mole guns are typically handmade. Some examples of injuries and deaths caused by mole guns are also offered.

    The Pontides formed the southern active margin of Laurasia during the Mesozoic. They became separated from mainland Laurasia during the Late Cretaceous, with the opening of the Black Sea as an oceanic back-arc basin. During the Early Cretaceous, a large submarine turbidite fan complex developed in the Central Pontides. The turbidites cover an area of 400 km by 90 km with a thickness of more than 2 km. We have investigated the provenance of these turbidites-the Çağlayan Formation-using paleocurrent measurements, U-Pb detrital zircon ages, REE abundances of dated zircons and geochemistry of detrital rutile grains. 1924 paleocurrent measurements from 96 outcrop stations indicate flow direction from northwest to southeast in the eastern part of the Çağlayan Basin and from north-northeast to west-southwest in the western part. 1194 detrital zircon ages from 13 Lower Cretaceous sandstone samples show different patterns in the eastern, central and western parts of the basin. The majority of the U-Pb detrital zircon ages in the eastern part of the basin are Archean and Paleoproterozoic (61% of all zircon ages, 337 grains); rocks of these ages are absent in the Pontides and present in the Ukrainian Shield, which indicates a source north of the Black Sea. In the western part of the basin the majority of the zircons are Carboniferous and Neoproterozoic (68%, 246 grains) implying more local sources within the Pontides. The detrital zircons from the central part show an age spectrum as mixture of zircons from western and eastern parts. Significantly, Jurassic and Early Cretaceous zircons make up less than 2% of the total zircon population, which implies lack of a coeval magmatic arc in the region. This is compatible with the absence of the Lower Cretaceous granites in the Pontides. Thus, although the Çağlayan Basin occupied a fore-arc position above the subduction zone, the arc was missing, probably due to flat subduction, and the basin was largely fed from the Ukrainian

    2015-02-01

    This paper gives the first taxonomic description of the Upper Tournaisian-Lower Viséan rugose coral fauna of the Yaricak Formation (Aladag Unit, Central Taurides, South Turkey). Fifteen species belonging to twelve genera were identified, one species is newly described: Eokoninckocarinia gemmina. The corals are stratigraphically distributed in four assemblages. The two typical assemblages of the Upper Tournaisian are composed of widely distributed taxa (Uralinia, Caninia, Proheterelasma, Zaphrentites). The assemblage crossing the Tournaisian-Viséan boundary is characterized by Eurasian and cosmopolitan and widely distributed taxa (Calmiussiphyllum, Siphonophyllia, Bifossularia Amygdalophyllum, Caninophyllum, Keyserlingophyllum) and Asian taxa (Kueichouphyllum). The youngest assemblage, dominated by Eokoninckocarinia gemmina sp. nov., has yielded foraminifers Moliniacian (Lower Viséan) in age. These assemblages form a low diversity level-bottom community which is typical of the South Palaeotethys 'Kueichouphyllum Zone' extending along the Asian margin of Gondwana (Cimmerian Terrane) during Lower Carboniferous times. As in the other Cimmerian blocks, all the corals are solitary and colonial taxa are virtually absent. This absence is tentatively explained by the high palaeolatitude (c. 50°S) position of the Cimmerian Terrane in the southern part of the Palaeotethys Ocean for this time slice. A cold-water palaeo-current running eastward along the Gondwana margin might also be considered as it possibly could explain the wide distribution of the Kueichouphyllum fauna, restricted east of Africa in the southern coast of the Palaeotethys. Palaeoceanography, palaeoclimate and facies issues are discussed as possible causes of the diversity gradient observed between the eastern (Australia, Malaya) and the western (North Africa) margin of the Gondwana.

    Full Text Available The study area is located within the Central Anatolian Massif around Yeşilhisar (Kayseri. The oldest rock units in the area are ophiolitic rocks which are mainly found as gabbro and dunites. The gabbros are dark green,blackish green coloured and hard, thin-medium granular hipidiomorf textured. Main Composition of gabbroic rocks are hornblende, clinopyroxen, plagioclase, quartz and opaque minerals, sphene and spinel are accessory minerals. The dunites are yellowish, greenish yellow coloured and fragile and stockwork textured. The main components of the dunites are olivine, pyroxen and chromite. The gabbroic rocks are mainly toleitic and can be classified as metaaluminious rocks. Main and trace element variations indicate that the fractionation of hornblende and Fe-Ti oxide minerals. Ratio of Condridite normalized Light REE to Heavy REE displays no enrichment La/LuN = 0.26. Trace and REE contents of the gabbroic rocks indicate that these rocks were a product of MORB like source.

    The study area is the upper Manavgat River basin. It is located in the western part of the central Taurides. Two significant geomorphic features of this basin are the Kembos and Eynif structural poljes. This study focuses on the tectonic impacts on the development of poljes and the morphotectonic evolutionary history of the study region. The data were obtained through a detailed mapping of the faults, rocks, and geomorphic features. The evolutionary history of the basin begins with the NW-SE-trending karstic paleovalleys, which first formed on the erosional surfaces that are part of the early and middle Miocene contractional tectonic regime. The tributaries, which developed under the influence of the NW-SE-trending Pliocene strike-slip faults, joined the main trunk of the Manavgat River. Starting at the beginning of the Quaternary, the tensional tectonic regime became prominent, and then a series of graben-horst structures appeared. The Eynif and Kembos poljes formed within two of these structures. The underground capture of surface water occurred in the grabens. The waters of both poljes drain through swallow holes into the Manavgat River and then in to the Mediterranean Sea. The regional uplift rates (the downcutting rates) are as follows: 0.36 mm/y in the late Miocene (Tortonian-Messinian), 0.06 mm/y in the Pliocene, and 0.18 mm/y in the Quaternary periods, which are based on the geopmorphic data obtained from high erosional surfaces and the Manavgat River valley. The average downcutting/uplift rate is 0.18 mm/y in this region.

    Using Affymetrix 10K arrays, we searched for regions of homozygosity in 51 Turkish families including at least three members with either congenital or prelingual autosomal recessive non-syndromic sensorineural hearing loss (ARNSSNHL), and identified four families whose deafness mapped to the DFNB6 locus on 3p21 containing the TMIE gene. Mutation analysis revealed the p.R84W mutation in all four families. Screening of this mutation in 254 families with ARNSSNHL, without GJB2 mutations, revealed four additional affected families. A novel mutation was found in a non-complementary marriage between a deaf couple who were homozygous for p.R84W and p.W57X, respectively with two affected children who were compound heterozygotes. Six of the TMIE families originated from southeastern Anatolia, making p.R84W a common cause of hearing loss in that region with a relative frequency of 10.3% (95% CI is 2.5-18.1%). The overall prevalence of the p.R84W mutation in ARNSSNHL in Turkey is 2.4% (95% CI is 0.7-4.0%). Genotyping of single-nucleotide polymorphisms flanking the TMIE gene revealed a conserved haplotype, suggesting a single origin for p.R84W from a common ancestor 1250 years ago (95% CI is 650-2500 years). We conclude that p.R84W could be a common mutation in other Middle Eastern populations and should be included in mutation screening offered to individuals with ARNSSNHL.

    Aim: Bloodstream infections in hospitalized patients are one of the most important causes of morbidity and mortality despite antimicrobial therapy. Early diagnosis and treatment of these infections is crucial. The aim of this study was to evaluate the distribution and antibiotic susceptibility of bacteria isolated from blood cultures in a children’s hospital in the Southeastern Anatolia during an 18-month period. Material and Methods: 7 040 blood cultures which were sent from hospitalized patients in Gaziantep Children’s Hospital between 01.07.2010 and 01.01.2012 were evaluated. Results: A total of 7 040 blood cultures were evaluated in this study. Microbial growth was detected in 2075 (29.47%) blood cultures. The most frequently isolated bacteria were coagulase-negative staphylococci (%45.97) which were followed by Salmonella spp. (%7.8). 12.12% of enterococcal isolates were resistant to glycopeptide antibiotics. The most frequently isolated gram negative bacterium was Salmonella spp. 15.43% of Salmonella spp. showed decreased susceptibility against quinolones. The ESBL positivity rate of E. coli and K. pneumoniae strains was found to be 35.08% and 57.14%, respectively. The imipenem resistance rate of P. aeruginosa was found to be 33.33%. The most common nonfermentative bacterium was S. maltophilia. Conclusions: The distribution of bacteria isolated from blood cultures and antibiotic resistance rates differ among different regions of Turkey. Different results obtained in our study may be related with regional tendencies to infections and patient population. Distribution of infectious agents and antibiotic resistance rates should be evaluated at regular intervals. This will lead to establishment of proper antibiotic usage policies in our country.

    The Tunçbilek-Domaniç Basin is one of the Neogene basins containing economic coal deposits in western Anatolia, Turkey. The basin fill represents fluvial to lacustrine sedimentary units which are interlayered with volcanic rocks with bimodal composition. In order to reveal the stratigraphy and the exact ages of the basin fill and coal deposits, and to explore the tectonic evolution of the basin, we present new field data and Ar/Ar age data from the volcanic units. The field studies and the age data indicate that the whole basin fills were deposited between ~23 and ~19 Ma (Aquitanian-Early Burdigalian) without any unconformity. Taking into account the ages of the coal-bearing sedimentary units in the other Neogene basins in the region, it is concluded that most of the economic coal deposits in the western Anatolia were formed during Aquitanian. The field studies also show that the deposition of the sedimentary units in the basin was controlled by the NE-SW-trending strike- to oblique-slip normal faults. In a regional scale, tectonic evolution of the Tunçbilek-Domaniç Basin is linked to the differential stretching in the hanging wall of the southerly located, a crustal-scale low-angle detachment fault (the Simav detachment fault) that controlled the Early Miocene exhumation of the Menderes Extensional Core Complex.

    The effect of ice ages in speciation and diversification is well established in the literature. In Europe, the Iberian, the Italian and the Balkan peninsulas comprise the main glacial refugia, where the subsequent re-population of Europe started. Though not studied as extensively, Anatolia has also been hinted to be a potential glacial refugium for Europe, and with its proximity to the Caucasus and the Middle East at the same time, has potential to exhibit high levels of intraspecific diversity. The more ubiquitous use and cheaper availability of molecular methods globally now makes it possible to better understand molecular ecology and evolution of the fauna and flora in the genetically understudied regions of the world, such as Anatolia. In this review, the molecular genetic studies undertaken in Anatolia in the last decade, for 29 species of plants and animals, are examined to determine general phylogeographic patterns. In this regard, two major patterns are observed and defined, showing genetic breaks within Anatolia and between Anatolia and the Balkans. A third pattern is also outlined, which suggests Anatolia may be a center of diversity for the surrounding regions. The patterns observed are discussed in terms of their relevance to the location of suture zones, postglacial expansion scenarios, the effect of geographic barriers to gene flow and divergence time estimates, in order to better understand the effect of the geological history of Anatolia on the evolutionary history of the inhabitant species. In view of the current state of knowledge delineated in the review, future research directions are suggested.

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

  20. The Challenge of Characterising Large Assemblages of Exotic Materials: a case study of the obsidian from Domuztepe, SE Turkey

    2009-09-01

    Full Text Available Obsidian artefacts from Domuztepe (a large late Neolithic site in the Kahramanmaraş plain in south-east Turkey belonging to the Halaf culture and dated to c. 6000-5500 cal. BC account for about 18%, or some 10,000 artefacts, of the chipped stone assemblage. Obsidian is one of the few non-local materials at Domuztepe and as well as being used to make tools it is also used to make items of jewellery, mirrors, bowls and axe-like objects. We know from the geochemical analysis of a relatively small number of artefacts that the obsidian was imported from eight different and widely separated sources in Central, NE and SE Anatolia. These sources are between 200 and 900km distant from Domuztepe. All these factors suggest that obsidian was valued not only as a raw material for tool manufacture but also as a material from which to make luxury items. As an exotic material it is also likely to have a key role in forging and maintaining social and economic relationships, both within the site and more widely. Understanding of the origins of the obsidians and the form in which they were obtained, worked and used, context by context, is key to this. However, difficulties arise with provenancing such a large assemblage, not least because conventional geo-chemical methods are unfeasibly expensive. This article documents the approaches we have developed to overcome this problem.

    2016-02-01

    The Kırka borate deposit was deposited in a Miocene lacustrine basin which is closely associated with volcanic activity which lasted from Paleogene to the beginning of Quaternary. Borate mineralization alternates with claystone, mudstone, tuff and fine-layered limestone and mostly shows a lenticular structure. The mineral paragenesis is composed of borax, tincalconite, ulexite, kurnakovite, probertite, tunellite, colemanite, dolomite, smectite group minerals, illite and some firstly reported minerals for the Kırka deposit including hydrochloroborite, brianroulstonite, hilgardite-4M and searlesite minerals. In comparison to average values of earth crust, concentrations of Cs, Sr, Li, As and Se were significantly enriched with respective rates of 21, 15, 14, 3 and 188 folds. Regarding KY, KS1 and KS2 locations, there are differences in both element abundances and their geochemical tendencies which are attributed to variations in discharge regime and physico-chemical conditions of the depositional environment. Independent behaviour of B2O3 might indicate that boron is not associated with clays and carbonates and, therefore, most part of boron must be derived from volcanic activity (hydrothermal solutions, gases). REE data indicate that the Kırka borate deposit was formed in a sedimentary environment where highly alkaline (high pH) hydrothermal solutions also took part in borate precipitation process.

    This paper represents the first reports on the natural and anthropogenic radionuclides in Kestanbol granitic pluton and surrounding rocks, and coastal region of the Ezine town. To assess the radiological hazard of the natural radioactivity, the radium equivalent activity, the absorbed dose rate and the external hazard index were calculated, and in situ gamma dose rates were measured. The high-activity concentrations were measured in the pluton and sands, which was originated mainly from the pluton, due to the presence of zircon, allanite, monazite, thorite, uranothorite and apatite. The average activity concentrations of (238)U, (232)Th and (40)K are 174.78, 204.69 and 1171.95 Bq kg(-1) for pluton, and 290.36, 532.04 and 1160.75 Bq kg(-1) for sands, respectively. (137)Cs in Ezine region ranged from 0-6.57 Bq kg(-1). The average absorbed dose rate for the granitic and sand samples were calculated to be 251.6 and 527.92 nGy h(-1), respectively. The maximum contribution to the total absorbed gamma dose rate in air was due to the (232)Th (52.3% for pluton and 67.1% for sands). The Raeq activities of the pluton and sands are higher than the recommended maximum value of 370 Bq kg(-1) criterion limit of Raeq activity for building materials.

    Cretaceous HP/LT chloritoid-bearing metapelitic rocks crop out widely in the central part of the Pontides, northern Turkey. They are associated with eclogite to blueschist-facies metabasites and represent deep levels of an underplated subduction-accretion complex, which is tectonically overlain by low-grade HP phyllite/metasandstone intercalation along an extensional shear zone. Close to the shear zone, the footwall micaschists consist of quartz, phengite, paragonite, chlorite, rutile with syn-kinematic albite porphyroblast formed by pervasive shearing during exhumation. This type of micaschists is tourmaline-bearing and their retrograde nature suggests high-fluid flux along shear zones. Peak metamorphic assemblages are partly preserved in the chloritoid-micaschist farther away from the shear zone. Three peak metamorphic assemblages are identified and their PT conditions are constrained by pseudosections produced by Theriak-Domino and by Raman spectra of carbonaceous material: 1) garnet-chloritoid-glaucophane with lawsonite pseudomorphs (P: 17.5 ± 1 Kbar, T: 390-450 °C) 2) chloritoid with glaucophane pseudomorphs (P: 16-18 Kbar, T: 475 ± 40 °C) and 3) relatively high-Mg chloritoid (17%) with jadeite pseudomorphs (22-25 Kbar; T: 440 ± 30 °C) in addition to phengite, paragonite, quartz, chlorite, rutile. The last mineral assemblage is interpreted as transformation of the chloritoid + glaucophane assemblage to chloritoid + jadeite paragenesis with increasing pressure. Absence of tourmaline suggests that the chloritoid-micaschist did not interact with B-rich fluids during zero strain exhumation. Peak metamorphic assemblages and PT estimates suggest tectonic stacking within wedge with different depths of burial. 40Ar/39Ar phengite age of a pervasively sheared footwall micaschist is constrained to 100.6 ± 1.3 Ma and that of a chloritoid-micaschist is constrained to 91.8 ± 1.8 Ma suggesting exhumation during on-going subduction. Coupling and exhumation of the

    Sustaining the human ecological benefits of surface water requires carefully planned strategies for reducing the cumulative risks posed by diverse human activities. The municipality of Aksaray city plays a key role in developing solutions to surface water management and protection in the central Anatolian part of Turkey. The responsibility to provide drinking water and sewage works, regulate the use of private land and protect public health provides the mandate and authority to take action. The present approach discusses the main sources of contamination and the result of direct wastewater discharges into the Melendiz and Karasu rivers, which recharge the Mamasın dam sites by the use of artificial neural network (ANN) modeling techniques. The present study illustrates the ability to predict and/or approve the output values of previously measured water quality parameters of the recharge and discharge areas at the Mamasin dam site by means of ANN techniques. Using the ANN model is appreciated in such environmental research. Here, the ANN is used for estimating if the field parameters are agreeable to the results of this model or not. The present study simulates a situation in the past by means of ANN. But in case any field measurements of some relative parameters at the outlet point “discharge area” have been missed, it could be possible to predict the approximate output values from the detailed periodical water quality parameters. Because of the high variance and the inherent non-linear relationship of the water quality parameters in time series, it is difficult to produce a reliable model with conventional modeling approaches. In this paper, the ANN modeling technique is used to establish a model for evaluating the change in electrical conductivity (EC) and dissolved oxygen (DO) values in recharge (input) and discharge (output) areas of the dam water under pollution risks. A general ANN modeling scheme is also recommended for the water parameters. The modeling

    The Pliocene Etrüsk stratovolcano, located in the northeast of Lake Van (Eastern Anatolia; Turkey), is one of the important volcanic centres in the Eastern Anatolian collision zone. Mt. Etrüsk overlies a widespread volcanic plateau, consisting of basaltic and hawaiitic lavas formed by fissure eruptions between 4.9-4.5 Ma. These basic lavas contain a phenocryst phase consisting of olivine, plagioclase and clinopyroxene. Trace element ratio diagrams imply that these basic magmas were generated from a mantle that contained a clear subduction component that is related to the subducted sediments rather than fluids or altered oceanic crust. Results of the melting models on the basaltic plateau lavas indicate that there was a marked variation both in the mantle source mineralogy (i.e. the ratio of garnet peridotite to spinel peridotite in the source varies between 60/40% and 40/60%) and the degree of melting (i.e. F between 0.8-4%). This can be explained by a model in which magmas were generated by partial melting of both metasomatised lithospheric and deeper asthenospheric mantle sources in an extensional setting in response to the partial delamination of the lithospheric mantle of Eastern Anatolia and then mixed with each other during Pliocene times. Central eruptions that formed the Etrüsk volcano lasted ~ 600 kyr between 4.3-3.7 Ma during Zanclean times. The estimated depth of the Etrüsk magma chamber is ~ 9-12 km. The volcano erupted lavas with a rather narrow compositional range from latite to rhyolite, which are either transitional or mildly alkaline in character. The Etrüsk lavas contain plagioclase, clino- and orthopyroxene, biotite, K-feldspar and rarely, minor amounts of olivine and amphibole in the phenocryst phase. A composite chemo-stratigraphic section of the volcano and petrological models indicate that the evolved lavas of the Etrüsk volcano differentiated from a parental magma composition, which is similar to that of the most primitive plateau

    Here we documented the vertical displacement, slip rate, extension rate, and geochronology of normal faults within a narrow strip along the main strand of the Ecemiş Fault Zone. The Kartal, Cevizlik, and Lorut Faults are normal faults that have evident surface expression within the strip. Terrestrial cosmogenic nuclide geochronology revealed that the Kartal Fault deformed the 104.2 ± 16.5 ka aged alluvial fan surface and the Cevizlik Fault deformed the 21.9 ± 1.8 ka old moraine and talus fan surfaces. Our topographic surveys indicated 120 ± 10 m and 13.1 ± 1.4 m surface-breaking vertical displacements along the Kartal and Cevizlik Faults, respectively. Accordingly, we suggest a 1.15 ± 0.21 mm a-1 slip rate and 0.66 ± 0.12 mm a-1 extension rate for the last 104.2 ± 16.5 ka on the Kartal Fault, and a 0.60 ± 0.08 mm a-1 slip rate and 0.35 ± 0.05 mm a-1 extension rate for the last 21.9 ± 1.8 ka on the Cevizlik Fault. We believe that these structures are an integral part of intraplate crustal deformation in the Central Anatolia. They imply that intraplate structures such as the Ecemiş Fault Zone may change their mode through time; presently, the Ecemiş Fault Zone has been deformed predominantly by normal faults. The presence of steep preserved fault scarps along the Kartal, Cevizlik, and Lorut Faults point to surface-breaking normal faulting away from the main strand and particularly signify that these structures need to be taken into account for regional seismic hazard assessments.

    Full Text Available The effect of ice ages in speciation and diversification is well established in the literature. In Europe, the Iberian, the Italian and the Balkan peninsulas comprise the main glacial refugia, where the subsequent re-population of Europe started. Though not studied as extensively, Anatolia has also been hinted to be a potential glacial refugium for Europe, and with its proximity to the Caucasus and the Middle East at the same time, has potential to exhibit high levels of intraspecific diversity. The more ubiquitous use and cheaper availability of molecular methods globally now makes it possible to better understand molecular ecology and evolution of the fauna and flora in the genetically understudied regions of the world, such as Anatolia. In this review, the molecular genetic studies undertaken in Anatolia in the last decade, for 29 species of plants and animals, are examined to determine general phylogeographic patterns. In this regard, two major patterns are observed and defined, showing genetic breaks within Anatolia and between Anatolia and the Balkans. A third pattern is also outlined, which suggests Anatolia may be a center of diversity for the surrounding regions. The patterns observed are discussed in terms of their relevance to the location of suture zones, postglacial expansion scenarios, the effect of geographic barriers to gene flow and divergence time estimates, in order to better understand the effect of the geological history of Anatolia on the evolutionary history of the inhabitant species. In view of the current state of knowledge delineated in the review, future research directions are suggested.

    2015-04-01

    A detailed taxonomical study was carried out for the identification of encrusting micro-organisms including Bacinella-type structures, Calcistella jachenhausenensis, Crescentiella morronensis, Iberopora bodeuri, Koskinobullina socialis, Labes atramentosa, Lithocodium aggregatum, Perturbatacrusta leini, Pseudorothpletzella schmidi, Radiomura cautica, Sarsteinia babai, Terebella lapilloides and Thaumatoporella parvovesiculifera. Among these microencrusters, Perturbatacrusta leini, Iberopora bodeuri, Calcistella Jachenhausenensis, Pseudorothpletzella schmidi have been taxonomically revealed for the first time in Turkey. Within the biostratigraphic frame of the İnalti carbonates consisting of Mesoendothyra izjumiana zone (Kimmeridgian), Calcistella jachenhausenensis zone (Lower Tithonian - Upper Tithonian) and Protopeneroplis ultragranulata zone (Upper Tithonian - Berriasian), carbonate sedimentation occured in 5 depositional environments comprising slope, fore-reef, reef, back-reef and lagoonal environments. Majority of the reefal deposits of the İnalti carbonates can be classified as coral-microbial-microencruster boundstones and frequently occur associated with back-reef and fore-reef deposits within Kimmeridgian - Berriasian interval. A shallowing and a subsequent deepening in the Berriasian have been revealed by the examination of stacking patterns and vertical evolution of the microfacies. Based on the observed microfacies and general features of micro-encrusting organisms it has been concluded that İnalti Limestones share many similarities with the reefal carbonate deposits of Intra-Tethyan domain in terms of microfacies types and microencruster content. These similarities manifest the extension of the European Upper Jurassic - Lower Cretaceous reef belts to the northern Turkey.

  11. The Geopolitics of Water and Oil in Turkey

    2009-07-01

    Throughout history, few nations have been as successful in leveraging their geographic location as Turkey. As the center of two of the most powerful civilizations of all time, the Byzantine and Ottoman Empires, Turkey was the bridge between East and West, a bustling center of trade and a strategic economic and political nexus between regions of the world. In addition to its geographic power, Turkey has historically possessed substantial water resources. Unlike many water parched areas of the Middle East, Turkey's water capacity has allowed it to grow large populations and build elaborate cities. In the modern era, Turkey once again has an opportunity to regain its historical role, as the state where today's geopolitics of energy coincides with Turkey's traditional geopolitics of water. Turkey's central location, this time not between East and West, but between producers and consumers of energy, gives it a central, geopolitical role in world affairs, both in oil and gas. Moreover, Turkey's water resources can be utilized to reinforce Turkey's strategic energy role in the region, by building a strategy of cooperation with water-poor countries from the Levant to the Arabian Peninsula. Throughout history, water and energy have been among the most fundamental resources of civilization, at the very base of Maslow's hierarchy of needs essential to fostering human growth and development for thousands of years. It is seldom appreciated how linked water and energy truly are. Producing, transferring, and supplying energy requires a significant amount of water, just as the extraction, purification, and even desalination of water requires a significant amount of energy. As both energy and water grow scarcer throughout the future, nations such as Turkey can gain considerable influence as a result of their geographic locations and natural endowments. Turkey can benefit from pipeline diplomacy, taking advantage of its geographical location to

    Lake Van, a large terminal lake in eastern Anatolia (Turkey), holds a key position within a sensitive climate region between the Black Sea, Caspian Sea and Mediterranean Sea. Lake Van extends over 130 kilometers on a high plateau; lake level at present is 1665 meters above sea level. The lake water, up to 450 meters deep, is alkaline (pH ~9.8) and saline (~21.4‰). Its long and partly annually laminated sedimentary record provides an excellent paleoclimate archive because it yields a long and continuous continental sequence that covers several glacial-interglacial cycles spanning more than 500,000 years. Lake Van is therefore a key site to reconstruct Quaternary climate evolution in the near east. Moreover, being located in a tectonically active area bordered by two historically active volcanoes, it holds a unique paleoseismic and volcanic archive. As a closed and saline lake, Lake Van reacts very sensitively to lake level changes caused by any alterations in the hydrological regime in response to climate change. Because the lake is the deepest lake in Anatolia, which, in contrast to other more shallow lakes, likely never dried out in its history, it was identified as the most promising candidate to contain a long and continuous sediment archive. The drilling campaign, supported by the International Continental Scientific Drilling Program (ICDP), operated by the U.S.-based company Drilling, Observation and Sampling of the Earths Continental Crust (DOSECC), was carried on in July and August 2010. DOSECC developed and assembled a new Deep Lake Drilling System (DLDS) that was specifically designed for coring sediments from deep lakes and that was first operated in Lake Van. The DLDS worked at water depths of up to 360 meters. Cores from 140 meters (Northern Basin site) and 220 meters (AhlatRridge site) below the lake bed depth were retrieved. To obtain a complete sedimentary section, the two sites were cored multiple times. Total length of all parallel cores

    Objectives: Age estimation plays an important role in forensic medicine and orthodontics. Many methods of age estimation have been suggested. Demirjian method is the most frequently used one of these. In the literature, there is a little known about applicability of this method in Turkish children. The aim of the present study was to evaluate the reliability of Demirjian method of dental age estimaiton and for description of mandibular permanent tooth formation in Turkish children from the southwest Eastern Anatolia region.

    Materials and Methods: A retrospective study was performed on 1015 panoramic radiographs and 5-15 years of age South western of Eastern Anatolia Regionof Turkish children. The stages of dental maturity of the mandibular left seven permanent teeth for each subject using the eight radiographic dental maturity stages demonstrated by Demirjian’s method were evaluated. A pired t-test was used for statistical analysis.

    Results: The mean difference between the chronological and dental ages ranged 0,28 to 1,10 years in boys and from 0,18 to 0,68 years in girls. South western of Eastern Anatolia Region ofTurkish children were generally delayed in dental maturity compared with children in Demirjian sample. The differences between the chronological and dental ages were statistically significant in 6-6.9, 8-8.9, 9-9.9, 10-10.9, 11-11.9 years in boys and in 8-8.9, 9-9.9,11-11.9 years in girls.

    Conclusions: Turkish children from the southwest Eastern Anatolia region are significantly more delayed in dental maturity compared to Demirjian’s French-Canadian sample. The applicability of Demirjian data is not suitable for Southwestern of Eastern Anatolia Region of Turkish children.

    Full Text Available This paper examines how Turkey's domestic resources, which are Turkey's historical, cultural and political relations with the Turkic states and Turkey's economic interests in the region, affect Turkey's foreign relations with Azerbaijan, Kazakhstan, Kyrgyzstan, Turkmenistan and Uzbekistan. Findings show that the Turkic Republics' interest in Turkish development model gradually declined starting from the 1994s. The hypothesis that the stronger socio-cultural ties between Turkey and the Turkic states are the closer the foreign relations are between Turkey and the Turkic states is applicable to all five republics. In the field of business the study finds that Turkish economy follows a similar pattern in its relations with the Azerbaijani and the Central Asian market. Common policy goals of Turkey and the five states led Turkey to establish close foreign relations with these five regional countries. The hypothesis that the more Turkey has business interests in the Caspian Sea Region the more Turkey will have closer foreign relations with Turkic states is mostly apparent in the case of Azerbaijan. In the area of energy politics Turkey has its strongest link with Azerbaijan. Besides being strong economic partners Turkey is Azerbaijan's biggest supporter in the region against Armenia.

    2010-07-01

    The Lower to Middle Jurassic Mudurnu formation of the Sakarya Zone (Northern Turkey) was deposited in an extensional basin. This unit crops out along the southern Pontide range and consists of marine sedimentary rocks including debris flows, lignite-bearing clastic rocks and Ammonitico Rosso horizons alternating with mafic and felsic volcanic and volcaniclastic rocks. Magmatic rocks of the Mudurnu formation comprise two compositionally different groups; 1) a mafic group including diabase-microgabbro-basaltic lavas and their pyroclastic equivalents, and 2) a felsic group including granite porphyries and felsic pyroclastic rocks. All the magmatic members of the Mudurnu formation are subalkaline and display a calc-alkaline affinity. They are bimodal, with a significant silica gap between the mafic and felsic members with the exception of a few samples. These magmatic rocks display enrichment in LILE and depletion in Nb, Ta, P and Ti, implying a subduction-related magmatic signature. Melting modelling for the mafic rocks indicates that they originated possibly from subcontinental lithospheric mantle (SCLM) composed of spinel lherzolite. ɛNd(i) values (+ 1.5 to + 4.3) imply that the mafic volcanic and hypabyssal rocks were possibly derived from a time-integrated LREE-depleted mantle source. The initial Sr and Nd isotope values, and ɛNd(i) of the felsic hypabyssal rocks are comparable to the mafic ones. The isotope data point to a genetic relationship between the felsic and mafic members. Results obtained from the geochemical modelling of incompatible versus compatible trace elements show that the felsic rocks were derived from the mafic melts by fractional crystallization (FC) process. In the light of their regional geological setting and these geochemical characteristics, we propose that the magmatic rocks of the Mudurnu formation formed in an extensional basin situated on an active and/or just ended subduction zone during the Jurassic period.

    ABSTRACT A new phlebovirus, Adana virus, was isolated from a pool of Phlebotomus spp. (Diptera; Psychodidae) in the province of Adana, in the Mediterranean region of Turkey. Genetic analysis based on complete coding of genomic sequences indicated that Adana virus belongs to the Salehabad virus species of the genus Phlebovirus in the family Bunyaviridae. Adana virus is the third virus of the Salehabad virus species for which the complete sequence has been determined. To understand the epidemiology of Adana virus, a seroprevalence study using microneutralization assay was performed to detect the presence of specific antibodies in human and domestic animal sera collected in Adana as well as Mersin province, located 147 km west of Adana. The results demonstrate that the virus is present in both provinces. High seroprevalence rates in goats, sheep, and dogs support intensive exposure to Adana virus in the region, which has not been previously reported for any virus included in the Salehabad serocomplex; however, low seroprevalence rates in humans suggest that Adana virus is not likely to constitute an important public health problem in exposed human populations, but this deserves further studies. IMPORTANCE Until recently, in the genus Phlebovirus, the Salehabad virus species consisted of two viruses: Salehabad virus, isolated from sand flies in Iran, and Arbia virus, isolated from sand flies in Italy. Here we present the isolation and complete genome characterization of the Adana virus, which we propose to be included in the Salehabad virus species. To our knowledge, this is the first report of the isolation and complete genome characterization, from sand flies in Turkey, of a Salehabad virus-related phlebovirus with supporting seropositivity in the Mediterranean, Aegean, and Central Anatolia regions, where phleboviruses have been circulating and causing outbreaks. Salehabad species viruses have generally been considered to be a group of viruses with little medical or

  2. Block-like plate movements in eastern Anatolia observed by InSAR

    KAUST Repository

    Cavalie, Olivier

    2014-01-16

    The question whether continental plates deform internally or move as rigid blocks has been debated for several decades. To further address this question, we use large-scale interferometric synthetic aperture radar (InSAR) data sets to study how eastern Anatolia and its surrounding plates deform. We find that most of the deformation is focused at the North and East Anatolian faults and little intraplate deformation takes place. Anatolia is therefore moving, at least its eastern part, as a uniform block. We estimate the slip velocity and locking depth of the North Anatolian fault at this location to be 20 mm/yr and ~14 km, respectively. High deformation gradient found near the East Anatolian fault, on the other hand, suggests that little stress is accumulating along the eastern sections of that fault.

    In the Late Cretaceous, throughout the closure of the Neotethys Ocean, ophiolitic rocks from the İzmir-Ankara-Erzincan ocean branch were overthrusted the northern margin of the Tauride-Anatolide Platform. The ophiolitic rocks in the Ekecikdaǧ (Aksaray/Central Turkey) region typify the oceanic crust of the İzmir-Ankara-Erzincan branch of Neotethys. The gabbros in the area are cut by copious plagiogranite dykes, and both rock units are intruded by mafic dykes. The plagiogranites are leucocratic, fine- to medium-grained calc-alkaline rocks characterized mainly by plagioclase and quartz, with minor amounts of biotite, hornblende and clinopyroxene, and accessory phases of zircon, titanite, apatite and opaque minerals. They are tonalite and trondhjemite in composition with high SiO2 (69.9-75.9 wt%) and exceptionally low K2O (<0.5 wt%) contents. The plagiogranites in common with gabbros and mafic dykes show high large-ion lithophile elements/high-field strength element ratios with depletion in Nb, Ti and light rare-earth elements with respect to N-MORB. The plagiogranites together with gabbros and mafic dykes show low initial 87Sr/86Sr ratios (0.70419-0.70647), high ƐNd(T) (6.0-7.5) values with 206Pb/204Pb (18.199-18.581), 207Pb/204Pb (15.571-15.639) and 208Pb/204Pb (38.292-38.605) ratios indicating a depleted mantle source modified with a subduction component. They show similar isotopic characteristics to the other supra-subduction zone (SSZ) ophiolites in the Eastern Mediterranean to East Anatolian-Lesser Caucasus and Iran regions. It is suggested that the Ekecikdaǧ plagiogranite was generated in a short time interval from a depleted mantle source in a SSZ/fore-arc basin setting, and its nature was further modified by a subduction component during intra-oceanic subduction.

    The Kula European and Global Geopark is situated in the Aegean Region of Turkey at Western Anatolia, within Manisa Province. The Geopark area covers 300 km2. The Kula Geopark area is the youngest volcanic region of Turkey where the volcanic activity continued up to prehistoric times. The outstanding volcanic structures of Kula Geopark area are well known at least for 2 thousand years. The great ancient Greek Geographer Strabo (63BC-24AD) in his majestic book "Geographica" named Kula as "Katakekaumene" (fire-born) because of the coal black lava. The geological significance and the cultural richness of Kula was mentioned by many foreign travellers and researchers like Charles Texier (1832) "Asia Minor" and Henry Washington's PhD thesis in 1893 where he named Kula basalts as "Kulaite". Kula Geopark area is awarded with high geodiversity representing 200 million years of earth history from Palaeozoic to Holocene including maars, monogenic cinder cones, successive lava flow plains, lava caves and tubes, craters, basalt columns, xenoliths, contact metamorphism, ash deposits, waterfalls in volcanic canyons, active karstic caves, badlands and fairy chimneys, mesa structures and schist tor, as far as 15 thousand years of fossil human foot prints preserved in volcanic ash. Kula Geopark is the land of miniature volcanoes where cinder cones are not higher than 150m. As a result, the geosites are easy to access and visiting the area requires very little risk, effort and time which makes the area excellent for geotourism and geoeducation. In addition to these outstanding natural and geological heritages, Kula Geopark reveals rich cultural, architectural historical, archaeological, and paleontological monuments. Kula represents well-preserved monuments of the 18th century Ottoman urban architecture in Turkey. The Kula Geopark Project was initiated in 2011 by PhD Erdal Gümüş with the support of the Kula Municipality. In September 2013 the Kula Geopark was certified as the first

Deformation pattern in the area is controlled by three major E-W trending graben systems of Gediz, Küçük Menderes and Büyük Menderes which have been formed as a result of roughly N-S extensional tectonic regime since the early Miocene. These graben systems show evidences of surface faulting during the Pleistocene-Holocene and are geomorphologically characterized by well-exposed limestone normal fault scarps with a relief of tens of meters and well-preserved slickenlines. Since limestones are resistant to weathering, the limestone scarps can efficiently record several past earthquakes. Cosmogenic 36Cl is the only element to identify and date the rupture events. Each rupture causes exposure of previously buried section of the scarp to the surface. Accordingly, due to being well enough exposed to cosmic rays, accumulation of 36Cl accelerates during period of quiescence. Thus, distribution of measured 36Cl concentrations can be applied to investigate periods of seismic activity and inactivity and also to calculate the vertical displacement along the fault plane in association with each rupture. In this study, we focus on the Priene-Sazli Fault, located on the most western part of Büyük Menderes graben. Along the active fault zone, well exposed archaeological sites (e.g. Priene) have been discovered, where destructive historical earthquakes have left evidence of ancient damages in the historical period and during the 20th century. The Priene-Sazli Fault caused the July 16, 1955 Söke-Balat earthquake (M=6.8) with fault-plane solution indicating of normal southeast downthrow along with subsidiary dextral motion. We collected 117 samples from four continuous strips on the Priene-Sazli Fault to measure 36Cl concentrations. We used a new Matlab code to identify the significant ruptures and their timing. Our preliminary results reveal the evidence of enhanced seismic activities along the Priene-Sazli Fault during the early Holocene.

    Integrated geophysical investigations consisting of joint application of various geophysical techniques have become a major tool of active tectonic investigations. The choice of integrated techniques depends on geological features, tectonic and fault characteristics of the study area, required resolution and penetration depth of used techniques and also financial supports. Therefore, fault geometry and offsets, sediment thickness and properties, features of folded strata and tectonic characteristics of near-surface sections of the subsurface could be thoroughly determined using integrated geophysical approaches. Although Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT) and Seismic Refraction Tomography (SRT) methods are commonly used in active tectonic investigations, other geophysical techniques will also contribute in obtaining of different properties in the complex geological environments of tectonically active sites. In this study, six different geophysical methods used to define faulting locations and characterizations around the study area. These are GPR, ERT, SRT, Very Low Frequency electromagnetic (VLF), magnetics and self-potential (SP). Overall integrated geophysical approaches used in this study gave us commonly important results about the near surface geological properties and faulting characteristics in the investigation area. After integrated interpretations of geophysical surveys, we determined an optimal trench location for paleoseismological studies. The main geological properties associated with faulting process obtained after trenching studies. In addition, geophysical results pointed out some indications concerning the active faulting mechanism in the area investigated. Consequently, the trenching studies indicate that the integrated approach of geophysical techniques applied on the fault problem reveals very useful and interpretative results in description of various properties of faulting zone in the investigation site.

    The Kavak geothermal field is located 13 km north of Seydişehir town, about 90 km southwest of Konya Province in the Central Anatolia, Turkey. This study was carried out to determine the origin, chemical characteristics, and isotopic composition of Kavak thermal waters. The measured temperatures of thermal and mineral waters range from 21.5 to 26 °C with a discharge of 0.8 l/s in springs, and from 30 to 45.8 °C with a discharge of 185 l/s in wells. Thermal and/or mineralized spring and well waters are of Casbnd Nasbnd HCO3 types with electrical conductivity ranging from 2530 to 4150 μS/cm while cold groundwater is mainly of Casbnd HCO3 and Casbnd Mgsbnd HCO3 types with electrical conductivity ranging from 446 to 668 μS/cm. Kavak thermal waters have not reached complete chemical re-equilibrium possibly as a result of mixing with cold water during upward flow. Assessments from quartz geothermometers and fluid-mineral equilibria calculations suggest that reservoir temperature of Kavak geothermal field ranges from 68 to 105 °C. Thermal waters are oversaturated at discharge temperatures for calcite, dolomite, and aragonite minerals corresponding to travertine precipitation in the discharge area. Gypsum and anhydrite minerals are undersaturated in all the thermal waters. The δ18O and δ2H compositions of Kavak thermal and cold waters point to a meteoric origin. Meteoric waters infiltrate the reservoir rocks along faults and fracture zones. After being heated at depth with the high geothermal gradient, they move up to the surface along faults and fractures that act as pathways. Additionally, δ18O and δ2H values suggest that thermal waters are recharged from higher elevations in comparison with cold waters. Long-term circulation of meteoric waters within the basement rocks is indicated by low tritium (<2 TU) values in the thermal waters, although the fluids do not achieve thermodynamic equilibrium. Based on the δ13C values, carbon in thermal waters is considered

In this study, assessments of the levels of service perceived and expected by the customers under four different dimensions (staff, programme, locker rooms and facility were carried out in order to identify the levels of fitness centers in terms of service quality. The replies provided by 219 members of fitness center who filled out the scale form voluntarily and without skipping any parts were evaluated. In order to measure the service quality of fitness in the study, Service Quality Assessment Scale (SQAS, which was developed by Lam et al. (2005 and whose Turkish adaptation was done by Gürbüz et al. (2005, was used. The SQAS was composed of 4 dimensions (staff, programme, locker rooms and facility and 34 items. In assessing the service quality, Gap Model (Parasuraman, Zeithaml and Berry, 1988 was used; though this method, the gaps were identified by subtracting perception scores from expectation scores. In order to find the differences between the groups, “Paired-Samples "t" test”, “Independent Samples "t" test” and “One way ANOVA” were utilized. When the results obtained and the differences between perception and expectation scores were assessed in terms of dimensions, it was observed that all dimensions had a negative difference. In terms of statistics, it was discovered that there was a meaningful difference in all of staff, programme, locker rooms and facility at the level of p<0,05. Among those, the lowest level of quality was observed to belong to “programme” dimension with the unit of -0,564. Later, with the -0,509-unit difference “locker rooms” dimension, with the -0,487-unit difference “staff” dimension and with the -0,481-unit difference “facility” dimension follow respectively.

    In Turkey, rapid population growth, informal settlements, and buildings and infrastructures vulnerable to natural hazards are seen as the most important problems of cities. Particularly disaster risk cannot be disregarded, as large parts of various cities are facing risks from earthquakes, floods and landslides and have experienced loss of lives in the recent past. Urban regeneration is an important planning tool implemented by local and central governments in order to reduce to disaster risk and to design livable environments for the citizens. The Law on the Regeneration of Areas under Disaster Risk, commonly known as the Urban Regeneration Law, was enacted in 2012 (Law No.6306, May 2012). The regulation on Implementation of Law No. 6306 explains the fundamental steps of the urban regeneration process. The relevant institutions furnished with various authorities such as expropriation, confiscation and changing the type and place of your property which makes urban regeneration projects very important in terms of property rights. Therefore, urban regeneration projects have to be transparent, comprehensible and acceptable for all actors in the projects. In order to understand the urban regeneration process, the legislation and projects of different municipalities in Istanbul have been analyzed. While some steps of it are spatial data demanding, others relate to land values. In this paper an overview of the urban regeneration history and activities in Turkey is given. Fundamental steps of the urban regeneration process are defined, and particularly spatial-data demanding steps are identified.

    Tuberculosis is a disease as old as human history and has affected every area of human life. The struggle against tuberculosis had been started by non-governmental organizations and achieved success after second world war. In Anatolia as well as all over the world fight against tuberculosis, with the leading names in medicine, started during the Ottoman Empire. In the following years of struggle within the executive team will host association (Istanbul Anti-tuberculosis Association) was founded in 1918. Due to political developments that occurred shortly after standing association studies, in 1923, the Republic of Turkey in Izmir during the re-started. In the 1925 and 1927 a national medical congress, tuberculosis as the main election issue, was organized, and then in 1928 in Istanbul Tuberculosis Association again take action in the fight against decisive role in association studies have begun to undertake. In the years 1953-1973, UNICEF, Ministry of Health and later efforts Turkish National Anti-tuberculosis Association jointly significant results were obtained in the fight against tuberculosis. These positive statements given the lethargy environment, economic and political crises in the last 10 years, in parallel with the increase of tuberculosis around the world experiencing, there was an increase in Turkey. In 1986, the National Anti-Tuberculosis Federation was founded by Anti-Tuberculosis Associations. The Anti-Tuberculosis Federation has put in practice DOTS programme in 2005 in Turkey. In conclusion, we evaluate that the Anti-Tuberculosis Associations in Turkey have played a major role in struggle against tuberculosis in Turkey since the last century.

    One hundred and nineteen Merriam's wild turkeys (Meleagris gallopavo merriami) and 31 domestic chickens coexisting on a ranch in west-central Colorado (USA) were surveyed for mycoplasmosis by serologic and cultural methods. Although no clinical signs were apparent in any wild turkeys tested, 51 (43%) had positive rapid plate agglutination (RPA) reactions for M. gallisepticum (MG) and/or M. synoviae (MS); 37% of 56 adults and 48% of 63 subadults were classified as positive reactors to MG and/or MS. No turkeys tested in 1992 (n = 61) and 17 (29%) of 58 turkeys tested in 1993 were RPA-positive for M. meleagridis (MM). Hemagglutination inhibition (HI) test results were negative for MG, MS and MM as were most enzyme-linked immunosorbent assay (ELISA) test reactions (MG = 99%, MS = 93%, MM = 87%). Immunoblotting showed mild to moderate reactivity to MG proteins in 49% of 41 samples tested. Most chickens were strongly positive for MS by RPA (81%), HI (58%) and ELISA (87%); 48% also were positive for MG by RPA but all were MG-negative by HI and ELISA. No pathogenic mycoplasmas were isolated from either group of birds. Mycoplasma gallopavonis was commonly identified from the wild turkeys, and M. gallinaceum was isolated from both the chickens and wild turkeys. In a transmission study conducted in 1994, disease-free domestic turkeys failed to seroconvert when co-housed with wild turkeys from this population that were RPA-positive for MG. Collectively, the results of this study were inconclusive regarding the status of pathogenic mycoplasmas within this wild turkey population.

    A continent-oceanic island arc collision model was proposed as a new geodynamic scenario for the evolution of the Cretaceous Central Anatolian granitoids in the Central Anatolian crystalline complex (CACC) by Boztug et al. (2007b) [Boztug, D., Tichomirowa, M., Bombach, K., 2007b. 207Pb-206Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust, Turkey. Journal of Asian Earth Sciences 31, 71-86]. The key aspects of this model include an intra-oceanic subduction in the Neotethyan Izmir-Ankara Ocean, formation of an island arc and its subsequent collision with the northern margin of the Tauride-Anatolide Platform. The identical scenario was initially proposed by Göncüoglu et al. (1992) [Göncüoglu, M.C., Erler, A., Toprak, V., Yalınız, K., Olgun, E., Rojay, B., 1992.

    Full Text Available Late Preclassic (300 BC-AD 100 turkey remains identified at the archaeological site of El Mirador (Petén, Guatemala represent the earliest evidence of the Mexican turkey (Meleagris gallopavo in the ancient Maya world. Archaeological, zooarchaeological, and ancient DNA evidence combine to confirm the identification and context. The natural pre-Hispanic range of the Mexican turkey does not extend south of central Mexico, making the species non-local to the Maya area where another species, the ocellated turkey (Meleagris ocellata, is indigenous. Prior to this discovery, the earliest evidence of M. gallopavo in the Maya area dated to approximately one thousand years later. The El Mirador specimens therefore represent previously unrecorded Preclassic exchange of animals from northern Mesoamerica to the Maya cultural region. As the earliest evidence of M. gallopavo found outside its natural geographic range, the El Mirador turkeys also represent the earliest indirect evidence for Mesoamerican turkey rearing or domestication. The presence of male, female and sub-adult turkeys, and reduced flight morphology further suggests that the El Mirador turkeys were raised in captivity. This supports an argument for the origins of turkey husbandry or at least captive rearing in the Preclassic.

    The geochemistry of oil shale units of Hançili Formation in the Çankırı-Çorum Basin (Central Turkey) was studied using various chemical analyses. The mineralogical composition of the samples were preliminarily investigated using Pearson's correlation coefficients of selected elements, indicating that the samples contain abundant clay minerals as well as K-feldspar and carbonate. The K2O/Al2O3 and SiO2/Al2O3 ratios indicate that the major proportion of clay minerals is composed of smectite. Si, Al, Ti, K, Na, and Fe reside in clay minerals, while Ca, Mg, and Mn are mostly associated with carbonates (e.g., calcite and dolomite) and phosphorous (P) is present as apatite. The total REE content of the oil shale range from 19 to 113 ppm. The chondrite-normalized patterns of the oil shale show LREE enrichments, HREE deficits, negative Eu anomalies and negligible Ce anomalies. In general, major, trace and rare earth element abundances suggest that the studied oil shale in the Çankırı-Çorum Basin are mainly from the intermediate rocks, mixed with small amounts of basic rocks, and that their source rocks are mostly deposited in the continental collision setting. The REE geochemistry of the oil shale suggests that these samples were derived from a consistent terrigenous source and the Eu anomaly was inherited from the source rocks. The paleoclimate index (C-value), varies between 0.07 and 1.22 reflecting a generally semi-arid to humid conditions. In addition, Rb/Sr (~ 0.22) and Sr/Cu (~ 9.09) ratios support the idea that warm and humid conditions prevailed during deposition of the Hançili Formation. Sr/Ba ratios (0.54-3.7) of the studied samples suggest a paleoenvironment with variable salinity. The co-variation among this factor and paleoclimate indicators suggest that variations in climatic conditions exerted a primary control on salinity. The substantially low C-value and Rb/Sr ratio and significantly high ratios of Sr/Cu and Sr/Ba and also elevated carbonate

    Full Text Available Detailed analyses of the Lake Van pollen and stable oxygen isotope record allow the identification of millennial-scale vegetation and environmental changes in eastern Anatolia throughout the last glacial. The climate within the last glacial period (∼75–15 ka BP was cold and dry, with low arboreal pollen (AP levels. The driest and coldest period corresponds to Marine Isotope Stage (MIS 2 (∼28–14.5 ka BP dominated by the highest values of xerophytic steppe vegetation. Our high-resolution multi proxy record shows rapid expansions and contractions that mimic the stadial-interstadial pattern of the Dansgaard–Oeschger (DO events as recorded in the Greenland ice cores, and thus, provide a linkage to North Atlantic climate oscillations. Periods of reduced moisture availability characterized at Lake Van by enhanced xerophytic species correlates well with increase in ice-rafted debris (IRD and a decrease of sea surface temperature (SST in the North Atlantic. Furthermore, comparison with the marine realm reveals that the complex atmosphere–ocean interaction can be recognized by the strength and position of the westerlies in eastern Anatolia. Influenced by rough topography at Lake Van, the expansion of temperate species (e.g. deciduous Quercus was stronger during interstadials DO 19, 17–16, 14, 12 and 8. However, Heinrich events (HE, characterized by highest concentrations of ice-rafted debris in marine sediments, are identified in eastern Anatolia by AP values not lower and high steppe components not more abundant than during DO stadials. In addition, this work is a first attempt to establish a continuous microscopic charcoal record over the last glacial in the Near East, which documents an initial immediate response to millennial-scale climate and environmental variability and enables the shed light on the history of fire activity during the last glacial.

    Erzurum, the biggest city of Eastern Anatolia Region in the Turkey, is located in Karasu Plain. Karasu Plain, located on the central segment of the Erzurum Fault Zone, is an intermountain sedimentary basin with a Miocene-Quaternary volcanic basement, andesitic-basaltic lava flows and fissure eruptions of basaltic lava. It was filled in the early Quaternary by lacustrine fan-delta deposits. The basin is characterized by NNE-SSW trending sinistral wrench faults on its eastern margin and ENE-WSW trending reverse faults on its southern margin. Both systems of active faults intersect very near to Erzurum, which is considered to be the most likely site for the epicenter of a probable future large earthquake. Historical records of destructive earthquakes, morphotectonic features formed by paleo-seismic events and instrument seismic data of region indicate to a very high regional seismicity. The residential areas of Erzurum are located on thick alluvial fan deposits forming under the control of faults on the central segment of the Erzurum Fault Zone, which is one of the most active fault belts of the East Anatolian Region. Over time, the housing estates of city such as Yenisehir and Yildizkent have been expanded toward to the west and southwest part of Erzurum as a consequence of rapid and massive construction during the last 30 years. Geotechnical investigation has therefore been undertaken the residential areas of city in order to characterize geotechnical properties over the varied lithologies examine the potential for geotechnical mapping and assess the foundation conditions of the present and future settlement areas. The geological field observations and operations have been performed to make the soil sampling and characterize the lateral and vertical changes in thickness of the alluvial deposits in trenches, excavations and deep holes with 6-12 m sections. The soil samples have been subjected to a series of tests under laboratory conditions to obtain physical and

    Terminal Lake Van, the world's largest soda basin, is characterised by Na-CO3-Cl water chemistry (Reimer et al., 2008), salinity of ~22 ‰ and high pH of ~9.7. The sedimentary record of the lake goes ca. 600 ka back and documents major climatic events over that period (Stockhecke et al., 2014). Alas, the longevity of the basin does not mean that it persisted unchanged over such a long time. Information collected within the ICDP PALEOVAN project clearly suggests that upon its birth the chemistry of early Lake Van was very different from its modern alkaline equivalent. Here we document, by means of proxy data, the changes in water chemistry in a transforming basin. Results of lithological (Stockhecke et al., 2014) and micropaleontological (ostracod, gastropod and diatom assemblages) analysis, combined with geochemical data (δ18O, δ13C, Mg/Ca, Sr/Ca) obtained from the biogenic and authigenic carbonate fraction imply, that early Lake Van was a relatively shallow, fresh-to-brackish and, most probably, open basin. Sedimentological information points to tectonic factors rather than climatic changes responsible for closing the lake ca. 430 ka ago. Reimer, A., Landmann, G., Kempe, S., 2008.

    Full Text Available The epidemiology and clinical findings of scorpion stings in Sanliurfa region of Turkey, from May to September 2003, were evaluated in this study. Mesobuthus eupeus (M. eupeus plays a role on 25.8% of the scorpionism cases. This study also showed that intoxications caused by M. eupeus in the southeast of Anatolia region were seen in hot months of the summer, especially on July. Females and people above 15 years old were mostly affected and stung on extremities. Intense pain in the affected area was observed in 98.7% cases, hyperemia in 88.8%, swelling in 54.6%, burning in 19.7%, while numbness and itching were seen less frequently. In our study, the six most frequently observed symptoms were local pain, hyperemia, swelling, burning, dry mouth, thirst, sweating, and hypotension. In this study involving 152 M. eupeus toxicity cases, patients showed local and systemic clinical effects but no death was seen. Autonomic system and local effects characterized by severe pain, hyperemia and edema were dominantly seen in toxicity cases.

    The global energy requirement for sustaining economic activities, meeting social needs and social development is increasing daily. Environmentally friendly, renewable energy resources are an alternative to the primary non-renewable energy resources, which devastate ecosystems in order to meet increasing demand. Among renewable energy sources such as hydropower, biopower, geothermal power and solar power, wind power offers distinct advantages to Turkey. There is an increasing tendency toward wind globally and the European Union adjusted its legal regulations in this regard. As a potential EU Member state, Turkey is going through a similar process. The number of institutional and legal regulations concerning wind power has increased in recent years; technical infrastructure studies were completed, and some important steps were taken in this regard. This study examines the way in which Turkey has developed support for wind power, presents a SWOT analysis of the wind power sector in Turkey and a projection was made for the concrete success expected to be accomplished in the future.

    Over the past two decades, terrorism has exacted an enormous toll on the Republic of Turkey, a secular democracy with a 99.8% Muslim population. From 1984 to 2000, an estimated 30,000 to 35,000 Turkish citizens were killed by a nearly continuous stream of terrorism-related events. During this period, the Partiya Karekerren Kurdistan (PKK), a Kurdish separatist group (re-named KADEK in 2002), was responsible for the vast majority of terrorism-related events (and casualties), which disproportionately affected the eastern and southeastern regions of Turkey, in which the PKK has focused its activities. Most terrorist attacks over the past two decades have been bombings or shootings that produced or = 30 casualties (eight shootings, five bombings, and two arsons). The maximum number of casualties produced by any of these events was 93 in the Hotel Madimak arson attack by the Turkish Islamic Movement in 1993. This pattern suggests that terrorist attacks in Turkey rarely required more than local systems of emergency medical response, except in rural areas where Emergency Medical Services (EMS) are routinely provided by regional military resources. The last decade has seen the development of several key systems of local emergency response in Turkey, including the establishment of the medical specialty of Emergency Medicine, the establishment of training programs for EMS providers, the spread of a generic, Turkish hospital emergency plan based on the Hospital Emergency Incident Command System, and the spread of advanced training in trauma care modeled after Advanced Trauma Life Support.

    Turkey is one of seismogenic countries with destructive earthquakes. In Turkey, the 1999 Izumit Earthquake as the destructive earthquake occurred along the North Anatolian fault. This fault is crossing the Marmara sea. In this SATREPS project, Marmara Sea should be focused on because of a seismic gap in the North Anatolian fault. Istanbul is located around the Marmara Sea, so, if next earthquake in the Marmara will occur near Istanbul, fatal damages will be generated as compound damages including Tsunami and liquefaction etc. The Japan and Turkey can share our own experiences during past damaging earthquakes and we can prepare for future large earthquakes in cooperation with each other. In earthquakes in Tokyo area and Istanbul area as the destructive earthquakes near high population cities, there are common disaster researches and measures in each country. For disaster mitigation, we are progressing multidisciplinary researches in this SATREPS project. Our goals of this SATREPS project are as follows, This project is composed of four research groups. 1) The first group is Marmara Earthquake Source region observationally research group. This group has 4 sub-themes such as Seismicity, Geodesy, Electromagnetics and Trench analyses. 2) The second group focuses on scenario researches of earthquake occurrence along the North Anatolia fault and precise tsunami simulation in the Marmara region. 3) Aims of the third group are improvements and constructions of seismic characterizations and damage predictions based on observation researches and precise simulations. 4) The fourth group is promoting disaster educations using research result visuals. In this SATREPS project, we will integrate these research results for disaster mitigation in Marmara region and disaster education in Turkey. Finally, these results and knowledges will be applied to Japanese disaster mitigation researches and disaster educations. We will have a presentation of the updated results of this SATREPS

    West Nile virus (WNV), a mosquito-borne flavivirus with significant impact on human and animal health, has recently demonstrated an expanded zone of activity globally. The aim of this study is to investigate the frequency and distribution of WNV infections in potential vectors and several mammal and avian species in Turkey, where previous data indicate viral circulation. The study was conducted in 15 provinces across Turkey during 2011-2013. In addition, the entomological study was extended to 4 districts of the Turkish Republic of Northern Cyprus. WNV exposure was determined in humans, horses, sheep and ducks from Mersin, Sanliurfa, Van and Kars provinces of Turkey, via the detection of neutralizing antibodies. WNV RNA was sought in human and equine samples from Mersin, Adana and Mugla provinces. Field-collected mosquitoes from 92 sites at 46 locations were characterized morphologically and evaluated for viral RNA. Neutralizing antibodies were identified in 10.5% of the 1180 samples studied and detected in all species evaluated. Viral nucleic acids were observed in 5.9% of 522 samples but only in horses. A total of 2642 mosquito specimens belonging to 15 species were captured, where Ochlerotatus caspius (52.4%), Culex pipiens sensu lato (24.2%) comprise the most frequent species. WNV RNA was detected in 4 mosquito pools (1.9%), that comprise Oc. caspius Cx. pipiens s.l. and DNA barcoding revealed the presence of Cx. quinquefasciatus and Cx. perexiguus mosquitoes in infected Culex pools. All WNV partial sequences were characterized as lineage 1 clade 1a. These findings indicate a widespread WNV activity in Turkey, in Eastern Thrace and Mediterranean-Aegean regions as well as Southeastern and Northeastern Anatolia.

  12. Cretaceous to miocene palaeogegraphic evolution of Turkey: implications for hydrocarbon potential

    Energy Technology Data Exchange (ETDEWEB)

    The Cretaceous to Miocene palaeogeographic development of Turkey in general reflects the evolution of the various oceanic branches of Neo-Tethys together with interactions between the Laurasian and Gondwanan margins. At the beginning of the Cretaceous, the first-order palacotectonic units which make up present-day Turkey either formed parts of these supercontinents or were isolated continental blocks within the Neo-Tethys. In Aptian to Albian times, north-dipping subduction commenced along the southern margins of these units and resulted in the development of magmatic arcs and arc-related sedimentary basins. Coeval with the start of subduction, large-scale ophiolite abduction occurred on the units' passive margins. Terminal closure of the oceans' branches took place between the latest Cretaceous and the Miocene, forming the Anatolian orogenic collage whose outline defines present-day Turkey. Post-collisional intra-continental convergence continued until the late Miocene and resulted in north-south shortening of the collage. This shortening led to internal imbrication, thrusting and crustal thickening. It forced the Anatolian landmass westwards, away from east Anatolia where there has been continuous north-south compression since the Miocene between Laurasia and the Arabian Platform. Both the continental and the oceanic palaeotectonic units pose significant problems regarding their original geometry, size, depth, extent, contact relations, motion paths, subduction polarity, stratigraphy and timing of formation. Clarification of these issues is essential if the units' original paleogeographic relationships with respect to Neo-Tethys are to be reconstructed. This paper reviews some of these problems with the aid of a number of palinspastic and non-palinspastic maps. These maps are intended to provide a basis for evaluating the hydrocarbon potential of Turkey. (author)

    Full Text Available Water is one of our most critical resources. Civilization has historically flourished around major waterways. The most important uses of water are; agricultural, industrial and domestic use. This critical resource is under threat around the world. In the next 20 years, the quantity of water available to everyone is predicted to decrease by 30%. 40% of the world\\\\\\\\\\\\\\'s inhabitants currently have insufficient fresh water for minimal hygiene. In 2000 more than 2.2 million people died from waterborne diseases. Water politics is politics affected by water and water resources. There are connections between water resources, water systems, and international security and conflict. Today, water is a strategic resource in the globe and an important element in many political conflicts. Turkey can be faced severe water-stress in the near future. Therefore Turkey has to develop realistic and feasible water policy for future generations. [TAF Prev Med Bull 2011; 10(3.000: 327-338

    2010-12-01

    The Aegean region is the most seismically active domain in Western Anatolia which comprises Greece, the Hellenic Arc, and Western Turkey. The Aegean region is mainly under pure shear stress from an internally deforming counter-clockwise direction of the Anatolian Plate relative to the Eurasia Plate. Izmir is the third largest city in Turkey with 2.7 million population. The Tuzla Fault is lying between the town of Menderes and Cape Doganbey which has NE-SW lineament trending. It is 42 km long through the land with 3 right lateral strike slip segments. This fault has a great importance as its proximity to the city of Izmir. The study aims to perform a large scale investigation, focusing on the Tuzla Fault and its vicinity for better understanding of the region’s tectonics. A micro-geodetic network with 15 points has been established in the study area. In order to investigate the crustal deformation and relative displacements along the Tuzla Fault GPS and Precise leveling techniques were used. Observations of two GPS campaigns and two precise leveling measurements were performed in 2009 and 2010. In order to process collected data by GPS campaigns, GAMIT/GLOBK software was used. As a result of two GPS campaigns, the velocity vectors of points are rated between 21mm/yr to 25mm/yr. In addition, 6.6 mm vertical displacement was observed between two leveling benchmarks which seems critical and needs further investigation.

    Full Text Available The topmouth gudgeon Pseudorasbora parva is described as most invasive fish in Europe. It’s a small cyprinid fish native to East Asia. In 1982, the existence of this species was first recorded from the Thrace region of Türkiye. Todays it is recorded from Thrace to Ceyhan region. In this study was carried out Afyonkarahisar, Bilecik, Burdur, Denizli, Eskişehir, Isparta, Konya, Kütahya and Uşak provinces between 2001 and 2013. Specimens collected from various localities in these provinces. Our results are shown P. parva has invaded many freshwater systems in Türkiye. This species has a potential threat to the diversity of the ichthyofauna of Anatolia and fish farms because of causing an increased mortality pressure on some salmonids and cyprinids, and totally inhibiting spawning of existing native fish.

    Jean-Marc Gaspard Itard, a student of René Laennec's, first recognized pneumothorax in 1803, and Laennec himself described the full clinical picture of the condition in 1819. Treatment of pneumothorax was not begun as a standard procedure until World War II, but we think that Serefeddin Sabuncuoglu recognized the condition and applied treatment in the 15th century.Sabuncuoglu (1385-1470) was a surgeon who lived in Amasya (in Anatolia). In 1465, he completed Cerrahiyyetül Haniyye (Imperial Surgery), the 1st illustrated surgical textbook in the Turkish-Islamic medical literature. We describe the highlights of the book's recommendations concerning treatment of thoracic trauma, particularly of pneumothorax. We reproduce 2 of the colored miniature illustrations and add our comments regarding the advice of Sabuncuoglu. Most notably, he advocated "mihceme," a cupping therapy, as a simple technique of thoracic aspiration.

    2012-12-01

    Groundwater quality in the Kopruoren Basin located to the west of Kutahya city in western Anatolia was investigated. Kopruoren Basin is about 275 km2 with about 6,000 residents, but the surface and ground-water quality in this basin impacts a much larger population since the area is located upstream of Kutahya and Eskisehir plains. Groundwater occurs under confined conditions in the limestones of Pliocene units. The only silver deposit of Turkey is developed in the metamorphic basement rocks, Early Miocene volcanics and Pliocene units near Gumuskoy. The amount of silver manufactured annually comprises about 1% of the World's Silver Production. The cyanide-rich wastes of the Eti Gumus silver plant is stored in waste pools. There have been debates about the safety of this facility after a major collapse occurred in one of the pools in May 2011. In this study samples from 31 wells and 21 springs were collected in July and October 2011 and May 2012. The groundwaters are of Ca-Mg-HCO3 type, with arsenic, zinc and antimony occurring at high concentrations. Dissolved arsenic concentrations are as high as 48 ug/L in springs and 734 ug/L in well water. Arsenic in 57% of the springs and 68% of the wells exceeded the WHO guideline value (10 ug/L). Natural sources of arsenic in the area include the dissolution of arsenic-rich minerals such as realgar and orpiment associated with the mineral deposits in the southern part of the study area. In the northern part, arsenic is enriched due to the dissolution of arsenic-bearing coal deposits. Besides these natural sources of contamination, the silver mining activity could be an important anthropogenic source. The leakage of cyanide and arsenic, together with other trace elements to the environment from the waste pools, will continue to poison the environment if necessary precautions are not taken immediately.

    This paper investigates possible asymmetries in the monetary policy reaction function of the Central Bank of Republic of Turkey over the business cycles. It is found that the bank reacted more aggressively towards output stabilisation during recessions than expansions. The empirical evidence suggests that the inflation targeting policy of the Turkish Central Bank was accommodative rather than stabilising. Furthermore, it is found that although the Central Bank of Republic of Turkey responded to foreign reserves, real exchange rates and short-term capital inflows both in expansion and recession periods, the bank targeted money growth, budget deficits, and net foreign assets only in expansion periods.

Five year later World Health Organization (WHO declared the six effective approach for tobacco control, under the name of MPOWER. In the following years, WHO evaluated the level of implementation of MPOWER criteria in the countries. In this article, how Turkey implemented these six criteria will be discussed. Monitor tobacco use and prevention policies: Monitoring of tobacco use prevalence has been successfully monitored in Turkey through Global Adult Tobacco Survey, Global Youth Tobacco Survey and Health Professionals Tobacco Use Survey. Nevertheless, monitoring of tobacco industry activities was not successfully implemented. Protect people from tobacco smoke: Smoking was banned in most of the indoor public places in Turkey since 1996, and Turkey became a complete smoke-free country by the exposion of smoke-free places including the hospitality workplaces in 2008. Offer help to quit tobacco use: Although smoking cessation services has been a bit late in Turkey, availability of smoking cessation drugs and the establishment of free quitline services made Turkey successful in this regard. Warn about the dangers of tobacco: Since 1996, all TV channels have a duty of broadcasting programs on harms of tobacco use, not less than 90 minutes in a month and it has been implemented successfully. Additionally written messages indicating harms of tobacco has been printed on the packs since 1988 and pictures was added in 2010. But since the average surface area covered by the messages in less than 50% of the total surface of the pack, Turkey was not regarded as to meet the requirement. Enforce bans on tobacco advertising, promotion and sponsorship: All kinds of tobacco advertisement and promotion was banned by the Law in 1996. But the tobacco products was not in closed boxes at the sales points. Turkey was not found as successful

    Here we present magnetic properties of tephra layers in the cores taken from Lake Van, Eastern Anatolia, Turkey. Lake Van is the fourth largest terminal Lake in the world by volume (607 km3). It is 460 m deep and has a salinity of 21.4 per mil and a pH of 9.81. It is located on the East Anatolian Plateau with present day water level of 1648 m.a.s.l., and surrounded by large stratovolcanoes Nemrut, Suphan, Tendurek, and Ararat to the west and north. It has accumulated varved-sediments with tephra units, which all provide important paleoenvironmental records. After a seismic survey, four different locations were selected for coring in Lake Van, with water depths varying between 60 m and 90 m. Four cores having between 3 and 4.8 m length were analyzed for for element geochemistry using XRF Core Scanner analysis. The sub-samples were taken into plastic boxes with a volume of 6.4 cm3 for mineral magnetic analysis. The mineral magnetic measurements included magnetic susceptibility (χ), anhysteretic remanent magnetisation (ARM), isothermal remanent magnetisation (IRM), hysteresis properties and thermomagnetic analyses. According to the mineral magnetic measurements and geochemical analysis, we identified the five tephra layers (T1-T5). These tephra units were correlated with the previously varve-dated units of Landmann et al. (2011). The varve ages of the tephra layers were used to obtain the age-depth model for the cores. According to the age models the cores extend back to 9500 ka BP (varve years). Down-core profiles of all the magnetic properties are highly correlatable between different cores, suggesting that the magnetic records are of regional character. ARM values are found to be more convenient than χ values for correlating the tephra layers. The hysteresis parameters of samples taken from these layers indicate that they are within Pseudo Single Domain range. IRM curves show that low coersivity magnetic minerals are dominated in all tephra layers. Measurements

    In the course of an epidemiological study of glanders on a number of Turkish islands in the Sea of Marmara, 1128 horses were examined by using the intracutaneous mallein test. Thirty-five (3-1 per cent) developed an increase in rectal temperature and a swelling at the point of injection. Ten of these horses were killed and glanders was confirmed in five cases by the presence of lesions and by the immunohistological demonstration of the causative agent, Burkholderia mallei. Clinical and pathological findings indicated that in all cases the infection was restricted to the mucous membrane of the nasal cavity with its parasinus, the nostrils and the upper lips. It was confirmed that equine glanders is endemic in Turkey.

    Metals, organic carbon contents were determined in surficial and core sediment samples from Lake Bafa, Western Anatolia in 2010. The ranges of Fe, Mn, Pb, Cu, Ni, Cr, Zn and Hg contents of sediments from the Bafa Lake were 9.4-35 g kg(-1), 250-780, 2.3-20, 5.8-55, 1.2-480, 63-278, 26.6-79.9 and 0.013-0.273 mg kg(-1), respectively. The mean metal concentrations in surficial sediments obtained in this study decreased in the following order; Fe > Mn > Ni > Cr > Zn > Cu > Pb > Hg for Bafa lake. Total organic carbon concentrations of the bottom sediments from the Bafa Lake varied between 0.35% and 3.58%. The mean concentrations of metal were lower than the background levels in earth crust except Cr and Ni in the core sediments. The metal levels were evaluated according to the New Geo-accumulation Index, enrichment and contamination factors. The results confirmed that the Bafa Lake is not facing serious environmental pollution risk due to metal contamination except Hg. The levels of Cr, Ni, Cu, Fe, Zn and Mn generally appear to be uniformly distributed with depth except Hg and Pb due to anthropogenic sources in the core sediments.

    A Late Cretaceous Volcano-sedimantary Succession (LCVS) trends parallel to Neo-Tethyan Suture in North Central Anatolia. Volcanic members of the LCVS consist mainy of coeval leucite phonolite/tephrites, trachytes, lamprophyres and andesitic rocks. Obtained Ar-Ar ages reveal that the volcanic activity occurred between 73.6±0.18 and 76.78±0.19 Ma, contemporaneous with the subduction of the Neo-Tethyan ocean beneath the Pontides. The volcanic rocks of LCVS are classified as alkaline, High- to ultrahigh-K, and silica-saturated and silica-unsaturated, geochemically. Rare calc-alkaline andesitic lavas are also occur within the volcanic sucession. Except the calc-alkaline samples, magmatic members of LCVS have similar major and trace element concentrations similar to the plagioleucitites or ultrapotassic rocks of the active orogenic zones (i.e. the Roman Province ultrapotassic series, Peccerillo, 2005). The multi element patterns on N-MORB- and Chondrite-normalized spider diagrams are characterized by significant LILE and LREE enrichments relative to HFSE and HREE, and display apparent Nb and Ta depletions, implying the subduction-related magmas. 87Sr/86Sr(i) (0.704493-0.706090) and 143Nd/144Nd(i) (0.512523-0.512680) isotope ratios are close to the mantle array, and are also in between the Aeolian Islands CA-Potassic rocks (Peccerillo, 2005), BSE and the circum-Mediterranean anorogenic Cenozoic igneous province (CiMACI, Lustrino&Wilson, 2007). Variable Mg# (33-60) evidences that these rocks are the products of evolved melts. The lead isotope values display a trend between EMI and DM, suggesting that the crustal involvement is more effective process during the generation of some lamprophyres relative to the other ultrapotassic rocks of LCVS. The results of clinopyroxene thermobarometry calculations reveal significant differences in depth of crystallization for the rock suites. Some trace element abundances and inter elemental ratios together with their co-variations show

    Full Text Available In Turkey, Chickpea is in the first rank in pulses and it is followed by lentil, bean and faba bean respectively. In the world, Turkey is one of the most important producer and exporting countries especially for chickpea and lentil. In recent years, Turkey’s chickpea and lentil production are in downvard trend. Our country has diverse ecological regions for growing many pulses species. Our production potential of pulses must be evaluated and a great importance must be given to the production of cultivars with high yield potential, quality and standart bigness seed. On the other hand, in Turkey, winter chickpea production in coastal region and winter lentil production in central Anatolion region must be widened. Pulses production must be done by using proper growing techniques. Sowing and harvesting should be done by machine. At the same time good war should be made against disease and insect for increasing yield potential of pulses. So, in Turkey, pulses plantation can be increased much more than nowdays.

    Blackhead (histomoniasis, enterohepatitis) was diagnosed as the cause of death for three wild turkeys (Meleagris gallopavo silvestris) found in widely separated areas in Mississippi. The turkeys came from areas with high turkey population densities and supplemental feeding programs. Finding three sick and/or dead wild turkeys in a year's period suggests that the disease is more prevalent than generally believed. Recommendations for management programs are presented.

    Full Text Available Sandıras Mountain is located in southwest of Gölgeli Mountain, which lies parallel to border of Aegean and Mediterranean Regions, in Southwestern Anatolia. This mountainous area is one of the natural distribution areas of black pine (Pinus nigra Arn. and has the oldest black pine communities in Turkey. Monumental black pine stands and the large number of individual monumental trees can be observed between the 1200 and 2000 m elevations of the mountain (especially north slope of the mountain. In this paper, we present preliminary results of a dendrochronological research on old black pine trees of Sandıras Mountain. Four new tree-ring chronologies were built from upper and lower elevations of south and north slopes of the mountain. The shortest and the longest chronologies were 241 and 820 years-long (obtained from upper elevation of the north slope, respectively. In this research, we record the most sensitive black pine trees (mean sensitivity value is 0.27 of Turkey from the north slope of Sandıras Mountain.

    Full Text Available Turkey is a peninsula, surrounded by seas on three sides, with a total coastline of 8.333km. As a result of its heritage from ancient inland living culture, Turkey has a limited development in fishery production. However, there have been significant efforts in developing Trout Farming, compared to the other aquaculture products in Turkey. The recent developments in trout farming in Turkey have led to an increase in trout productions, providing alternatives for public nutrition. This study aims to assess the geographical distribution of trout farming and trout fish consumption in Turkey.

    The complex tectonic architecture of the eastern Mediterranean is mainly shaped by the interaction between the Eurasian, African, Arabian plates and smaller Anatolian Scholle. Ongoing post-collisional convergence between Eurasian and Arabian plates causes; (1) the westward motion of the Anatolia and and (2) the formation of four neo-tectonic provinces in Turkey: (a) East Anatolian Province of Shortening (b) North Anatolian Province (c) Central Anatolian "Ova" Province (d) West Anatolian Extensional Province. The Central "Ova" Province, which defines a region between the Aegean extensional regime in the west, the North Anatolian Shear Zone (NASZ) in the north and the East Anatolian Shear Zone (EASZ) in the east, is deformed internally by a series of NW-striking dextral and NE-striking sinistral strike-slip faults. The Malatya-Ovacık Fault Zone (MOFZ) is one the sinistral faults of the "Ova" province, located close to its eastern boundary. In order to understand not only the spatio-temporal behaviour of the MOFZ, but also its role in the internal deformation of the Anatolian Scholle we started to study the southern section, the Malatya Fault (MF), of this strike-slip fault zone in the framework of the TÜBITAK project no. 114Y580. The scope of the study is to calculate (a) the horizontal geologic slip rate, (b) the uplift rate, and (c) the cumulative displacement of the Malatya Fault (MF) that constitute the southwest part of MOFZ. Offset streams between 20-1700 m, pressure ridges, hot springs and small pull-apart basin formations are clear geological and geomorphological evidences for fault geometry along the MF. Among them the ~1700 m offset of the Tohma River (TR) presents unique site to understand deformational characteristics of the MF. Three levels of strath terraces (T1 to T3) identified along the both flanks of the TR by analyses of aerial photos and the field observations. The spatial distribution of these terraces are well-constrained by using the high

    Full Text Available OBJECTIVE: the different clinical and laboratory features and response to treatment of patients with acute brucellar epididymo-orchitis (BEO reporting to the reference hospital in Southeastern Anatolia of Turkey. MATERIAL AND METHODS: in this study, 27 male patients with brucellosis, who presented with epididymitis or epididymo-orchitis (EO at the university hospital in Diyarbakir from 1998 to 2006, were included. They were compared with the other male patients. Positive blood culture or high agglutination titers of > 1/160 and positive clinical manifestations of brucellosis were the main criteria for diagnosing brucellosis. RESULTS: fourteen patients had unilateral EO. Leukocytosis was present in 10 patients; all of them had initial agglutination titers of > 1/160 and 10 patients had a positive blood culture. All patients received combined therapy with streptomycin for the first 21 days (or oral rifampicin for 6-8 weeks with doxycycline or tetracycline for 6-8 weeks. All showed improvement, fever subsided in 3-7 days, and the scrotal enlargement and tenderness regressed. Only one patient had a relapse within one year. CONCLUSION: in brucellosis-endemic areas, clinicians encountering EO should consider the likelihood of brucellosis. In this study, young age was the most common risk factor, and leukocytosis and high CRP level were the most common laboratory findings. Most cases were unilateral. All patients responded to medical management very well. Conservative management with combination antibiotic therapy was adequate for managing BEO. Conclusively, brucellosis must be considered as a cause of orchitis, especially in endemic regions like Turkey.

    Full Text Available Both seismological and geodynamic research emphasize that the Aegean Region, which comprises the Hellenic Arc, the Greek mainland and Western Turkey is the most seismically active region in Western Eurasia. The convergence of the Eurasian and African lithospheric plates forces a westward motion on the Anatolian plate relative to the Eurasian one. Western Anatolia is a valuable laboratory for Earth Science research because of its complex geological structure. Izmir is a large city in Turkey with a population of about 2.5 million that is at great risk from big earthquakes. Unfortunately, previous geodynamics studies performed in this region are insufficient or cover large areas instead of specific faults. The Tuzla Fault, which is aligned trending NE–SW between the town of Menderes and Cape Doganbey, is an important fault in terms of seismic activity and its proximity to the city of Izmir. This study aims to perform a large scale investigation focusing on the Tuzla Fault and its vicinity for better understanding of the region's tectonics. In order to investigate the crustal deformation along the Tuzla Fault and Izmir Bay, a geodetic network has been designed and optimizations were performed. This paper suggests a schedule for a crustal deformation monitoring study which includes research on the tectonics of the region, network design and optimization strategies, theory and practice of processing. The study is also open for extension in terms of monitoring different types of fault characteristics. A one-dimensional fault model with two parameters – standard strike-slip model of dislocation theory in an elastic half-space – is formulated in order to determine which sites are suitable for the campaign based geodetic GPS measurements. Geodetic results can be used as a background data for disaster management systems.

    2016-04-01

    Western Turkey, with a >200 km long-belt of unmetamorphosed ophiolite overlying continental lithosphere is one or even the largest obducted ophiolite on Earth and therefore a key example to study obduction and early subduction dynamics. All Western Turkish ophiolite fragments are considered as part of the same Neotethyan branch resulting of a long-lived continental subduction (or underthrusting). Synchronous (ca. ~ 93 Ma) metamorphic sole formation and preservation at the base of most of the Turkish ophiolite fragments support this single event and place a strong constraint on the age of subduction initiation. Metamorphic soles are indeed generally considered to have formed during the early and hot subduction zone at 25 ± 10 km depths and welded to the overriding oceanic lithosphere. In Western Turkey however (as for most places worldwide) a systematic study of the pressure-temperature conditions with modern thermobarometric tools is generally lacking, and fundamental mechanisms of formation or accretion to the upper plate are poorly (if at all) constrained. We herein reappraise Western Turkish metamorphic soles focusing on the following points and issues: (i) detailed structures of metamorphic sole and other subduction derived units, petrological evolution and refined pressure-temperature conditions; peak pressure-temperature conditions of metamorphic sole were estimated using garnet, clinopyroxene, amphibole and plagioclase as the peak paragenesis at 10.5 ± 2 kbar and 800 ± 50°C based on pseudosections using the Theriak/Domino package (ii) the rather unique (and enigmatic) blueschist facies overprint found in places was investigated in terms of structural position and pressure-temperature conditions. Conditions of overprint were estimated around 12 kbar and 425 °C from the presence of glaucophane, lawsonite, jadeite and garnet overgrowing the amphibolite-facies assemblage. This field-based study provides clues to mechanisms of metamorphic sole underplating

    A survey was conducted to evaluate levels of indoor radon and gamma doses in 42 primary schools located in Batman, southeastern Anatolia, Turkey. Indoor radon measurements were carried out using CR-39 solid-state nuclear track detector-based radon dosimeters. The overall mean annual (222)Rn activity in the surveyed area was found to be 49 Bq m(-3) (equivalent to an annual effective dose of 0.25 mSv). However, in one of the districts (Besiri) the maximum radon value turned out to be 307 Bq m(-3). The estimated annual effective doses are less than the recommended action level (3-10 mSv). It is found that the radon concentration decreases with increasing floor number. The concentrations of natural and artificial radioisotopes were determined using gamma-ray spectroscopy for soil samples collected in close vicinity of the studied schools. The mean gamma activity concentrations in the soil samples were 31, 25, 329 and 12 Bq kg(-1) for (226)Ra, (232)Th, (40)K and (137)Cs, respectively. The radiological parameters such as the absorbed dose rate in air and the annual effective dose equivalent were calculated. These radiological parameters were evaluated and compared with the internationally recommended values.

    Seventy samples from major plutons (mainly granitic) of Western Anatolia (Turkey) have been analyzed by γ-ray spectrometry to determine the specific activities of 238U, 226Ra, 232Th and 40K (Bq/kg). Τhe natural radioactivity ranged up to 264 Bq/kg for 238U, 229.62 Bq/kg for 226Ra, up to 207.32 Bq/kg for 232Th and up to 2541.95 Bq/kg for 40K. Any possible relationship between the specific activities of 226Ra, 238U, 232Th and 40K and some characteristics of the studied samples (age, rock-type, colour, grain size, occurrence, chemical and mineralogical composition) was investigated. Age, major and trace element geochemistry, color, pluton location and mineralogical composition are likely to affect the concentrations of the measured radionuclides. The range of the Th/U ratio was large (0.003-11.374). The latter, along with 226Ra/238U radioactive secular disequilibrium, is also discussed and explained by magmatic processes during differentiation.

    Full Text Available A new species, Rossomyrmex anatolicus, is described from the Anatolian plains (Turkey. Although it is very similar to R. proformicarum because of the abundant pilosity, it can be distinguished by the petiole, which gradually narrows towards the apex. This character, together with the high number of hairs, can be used, also, to differentiate it from R. minuchae. The geographical distribution of the genus Rossomyrmex is discussed and compared with other taxa that also show disjointed distributions.Se describe Rossomyrmex anatolicus, nueva especie encontrada en las llanuras de Anatolia (Turquía.

    The Quaternary Süphan debris avalanche deposit is located in Eastern Anatolia, Turkey. The avalanche formed by the sector collapse of a major stratovolcano towards the north, possibly during a single catastrophic event. The deposit has an estimated volume of 4 km3 and ran out over 25 km to cover an area of approximately 200 km2. Products of the collapse are overlain by younger eruptive units from the Süphan volcano. We have tested the numerical code VolcFlow to first reproduce the emplacement of the Quaternary Süphan debris avalanche and then to develop a hazard assessment for potential future sector collapses and subsequent emplacement of debris avalanches and associated tsunami. The numerical model captures the main features of the propagation process, including travel distance, lateral spread, and run up. The best fit obtained for the existing flow has a constant retarding stress of 50 kPa and a collapse scar volume of 4 km3. Analysis of potential future collapse scenarios reveals that northern sector debris avalanches (up to 6 km3) could affect several towns. In the case of a sector collapse towards the south, a tsunami will reach the city of Van and several of the biggest towns on the southern shoreline of Lake Van. Cities most affected by the larger amplitude waves would be Van, Edremit, Gevaş, Tatvan, and, to a lesser extent, Erciş, with wave amplitudes (first waves after the onset of the collapse) between 8 and 10 m.

    In this study, it was aimed to determine dose-dependent interactions between phenolic contents and antioxidant, antibacterial and antifungal effect mechanisms of the infusions of Thymus haussknechtii Velen, naturally grown in the Eastern Anatolia region of Turkey. Therefore, the infusions of Thymus haussknechtii were tested and the interactions between phenolic contents and antioxidant, antibacterial and antifungal effect mechanisms were determined by way of different antioxidant, antibacterial and antioxidant test systems. The concentrations of Thymus haussknechtii showed strong hydrogen peroxide scavenging activity and free radical scavenging activity [1,1-diphenyl-2-picryl-hydrazil (DPPH) % inhibition]. Also, it was seen that Thymus haussknechtii infusions possessed strong antibacterial and antifungal activity against different gram negative and positive bacteria and fungi. In this study, positive correlations between antioxidant, antibacterial, antifungal potency and the total phenolic content of Thymus haussknechtii were found. When the concentration differences were examined, it was seen that concentrations of 4% had the most strong antioxidant, antibacterial and antifungal activity. As a result, Thymus haussknechtii can be reliable antioxidant, antibacterial antifungal substance at concentrations of 4% when it is used as a supplement to therapeutic regimens and for medicinal purposes.

    2016-01-01

    Full Text Available In this research, two well-recognized standard grape cultivars, Cabernet Sauvignon and Merlot, together with eight historical autochthonous grapevine cultivars from Eastern Anatolia in Turkey, were genetically characterized by using 12 pairs of simple sequence repeat (SSR primers in order to evaluate their genetic diversity and relatedness. All of the used SSR primers produced successful amplifications and revealed DNA polymorphisms, which were subsequently utilized to evaluate the genetic relatedness of the grapevine cultivars. Allele richness was implied by the identification of 69 alleles in 8 autochthonous cultivars with a mean value of 5.75 alleles per locus. The average expected heterozygosity and observed heterozygosity were found to be 0.749 and 0.739, respectively. Taking into account the generated alleles, the highest number was recorded in VVC2C3 and VVS2 loci (nine and eight alleles per locus, respectively, whereas the lowest number was recorded in VrZAG83 (three alleles per locus. Two main clusters were produced by using the unweighted pair-group method with arithmetic mean dendrogram constructed on the basis of the SSR data. Only Cabernet Sauvignon and Merlot cultivars were included in the first cluster. The second cluster involved the rest of the autochthonous cultivars. The results obtained during the study illustrated clearly that SSR markers have verified to be an effective tool for fingerprinting grapevine cultivars and carrying out grapevine biodiversity studies. The obtained data are also meaningful references for grapevine domestication.

    In Turkey, the three power plants (Yataan, Yenikoy, and Kemerkoy) in the southwestern part of Anatolia use Upper Miocene-Pliocene coal and cause environmental pollution in the winter. For this reason, some considerations have been given to the injection of CO{sub 2} from the power plants into the crust. A research project has been put into the practice for decreasing of global warming. Karstification and geological features, which are included in very thick carbonate rocks (a thickness over 2,000 m and limestone, dolomite, and marble from Paleozoic to Pliocene), and faults-lineaments have been considered as very important agents that will affect the injection of CO{sub 2}. The micro- and macro-karstification and lineament of the region have been studied, and the rocks of the area have been grouped into two classes based on the appropriateness of karstification as suitable and unsuitable rocks. Karstic and geological features (rocks and dislocation lines) have been compared together in a Geographic Information Systems (GIS); thus, by taking note of the geological-geomorphological characteristics of the area, a case study has been proposed for the CO{sub 2} injection from the Gokova power plant emissions with GIS applications, and suitable areas for the injection have been determined for further research.

    Thalassemias and hemoglobinopathies are a serious health problem in Turkey. There is a 70-year history of thalassemia in Turkey. The first patient with β-thalassemia major (β-TM) was reported in 1941. The first clinical and hematological studies were published by Aksoy in 1958. The overall incidence of β-thalassemia (β-thal) was reported by Çavdar and Arcasoy to be 2.1% in 1971. Important steps such as written regulations, education and prevention campaigns, have been taken to prevent thalassemia in Turkey by the Ministry of Health (MOH), the Turkish National Hemoglobinopathy Council (TNHC) and the Thalassemia Federation of Turkey (TFT) since 2000. A national hemoglobinopathy prevention program was started in provinces with a high prevalence by the MOH in 2003. While the percentage of premarital screening test was 30.0% of all couples in 2003, it reached 86.0% in 2013. While the number of newborn with thalassemias and hemoglobinopathies was 272 in 2002, it had dropped to 25 in 2010. There has been a 90.0% reduction of affected births in the last 10 years.

    2013-01-15

    The purpose of this report is to provide information about electric vehicles (EVs) and e-mobility as an emerging market in Turkey. EVs receive attention from the Turkish government for a number of reasons: Turkey has a strong automotive industry and needs to follow the technological developments taking place regarding intelligent vehicles and intelligent transport systems, as well as electric transportation technologies. Secondly, a considerable amount of carbon emissions from motor vehicles is of great concern in relation to climate change. EVs might be an alternative which can break the dependence of Turkey on imported fuel that has a negative influence on its current account deficit (CAD). On top of these factors, the Prime Minister of Turkey has a desire to have a 'Local Brand Vehicle' before the 100th year of the establishment of the Republic in 2023 and preferably an 'EV'. EVs are included in the strategy documents and action plans of almost all ministries and public institutions. Among all ministries, the Ministry of Science, Industry and Technology (MoSI and T) takes a leading position. It holds bi-annual meetings with stakeholders to monitor and evaluate progress about the level of actualization of the identified policies on e-mobility. MoSI and T's related institution of the Scientific and Technological Research Council of Turkey (TUBITAK) co-ordinates the R and D activities and provides generous R and D incentives. EVs have been put on sale in Turkey in 2012 and are still very limited in number. Public institutions are taking the lead by converting their vehicle fleet to EVs. EVs are also more suitable for businesses/ duties with a fixed/short route; therefore it is expected that the growth of the sector will mainly come from the vehicle fleet of the public organisations and institutions, followed by the private vehicle fleet of companies, e.g. freight companies. Although there are some on-going test drives, it is not yet proven

    SW Anatolian tectonics are dominated mainly by emplacement of Lycian Nappes from north to south over the Beydaǧları platform during the early to middle Miocene, which followed by the development of the so called Fethiye Burdur Fault Zone (FBFZ). This fault zone is supposed to be a sinistral strike-slip fault zone that accommodated more than 100 km displacement between the Menderes Massif and the Beydaǧları platform during the exhumation of the Menderes Massif, mainly during the late Miocene. In addition, the FBFZ is collinear with the on-land NE continuation of the Pliny Trench along which the north subducting African slab is thought to be torn apart and retreated from somewhere around the apex of Isparta Angle to its present configuration as a STEP fault. In order to test already proposed evolutionary scenarios, and the feasibility of a STEP fault scenario and tectonic evolution of the region, we have conducted a rigorous paleomagnetic and kinematic study in the region containing more than 3000 paleomagnetic samples collected from 88 locations distributed evenly all over SW Anatolia and more than 2000 fault slip data measured mainly along the FBFZ. According to our preliminary results, except for some local insignificant clockwise rotations - the region underwent counter-clockwise rotation during the early to Late Miocene. The rotation senses and amounts are almost the same everywhere implying that rotation took place uniformly everywhere, as a rigid body rotation or the region underwent no internal rotational deformation. Likewise, rotations in the west and the east of FBFZ are similar for the post-late Miocene implying no internal rotational deformation. In addition to paleomagnetic data, the slickenside pitches and constructed paleostress configurations mainly along the FBFZ indicated that the faults within the FBFZ are mainly normal in character although minor lateral components are observed at the fault terminations or intersections. These fault slip

    In this study, epiphytic lichen Xanthoria parietina was applied as the biomonitor of air pollution to determine the environmental influence in the vicinity of Soma coal-fired power plant. Thalli of lichen Xanthoria parietina growing on olive, oak and poplar trees were collected with their substrate in 2004-2006. They were taken from 44 different stations located in 3×3 km grids within an area of 30 km in diameter around the Soma power plant near the town of Soma. Lichen samples were analyzed by using the ICP-MS for As, Cd, Co, Cr, Cu, Fe, Hg, Ni, Pb, Se, Th, U, V and Zn elements and their concentrations were mapped. The sample analyses results were evaluated by using the statistical software (SPSS 11). Average element contents of samples were, in descending order, Fe > Zn > V > Pb > Cr > Cu > Ni > As > Co > U > Th > Se > Cd > Hg. Results obtained in the current study were generally found to be higher than the data reported in literature although some lower values exist for Cd, Co, Hg, Ni, Pb elements. The most polluted areas were found to be those in the vicinity of the coal-fired power plant, particularly along the direction of predominant wind and in the corridor which runs from west to southeast direction due to topographic conditions. We believe that this research which is conducted around a coal-fired power plant will shed light on future research on pollution.

    Varved sedimentary records have shown their high potential to reconstruct abrupt and global climate change within the marine realm (e.g. Cariaco Basin, Santa Barbara Basin). Continental counterparts, consisting of long and varved lacustrine records can be found in the subsurface of some deep lakes, such as Lake Van. Lake Van is a 440 m deep closed soda lake situated in a climatically sensitive semiarid and tectonically active region in Eastern Anatolia, Turkey. The ICDP project Paleovan aims to reconstruct the climatic, tectonic and volcanic history of Lake Van. Driven by an international and interdisciplinary scientific team, two sites, Ahlat Ridge (AR) and Northern Basin (NB) were drilled in summer 2010 recovering sedimentary records of 220 and 140 m, respectively. A total of 800 m of sediment-cores were opened, described and photographed in spring 2011 at the IODP core repository in Bremen. Lithologies of up to five parallel cores (multiple coring) were correlated and a composite profile was defined giving priority to core quality and continuity. Preliminary Ar/Ar dates of the core catcher yielded a basal ages of ~500´000 years. Using this rough age model, geochemical measurements (every 20 cm) indicate that TOC is high in warmer periods (interglacials) and low in colder periods (glacials). These TOC fluctuations match marine isotope stages and extrapolated Holocene sedimentation rates. The 219 m long AR composite profile consists of ~80 % lacustrine sediments, ~10 % of volcaniclastic deposits and 10 % gaps interpreted to be coarse-grained volcaniclastic that are difficult to be recovered. The lacustrine mud, i.e., clayey silt composed of mainly clay minerals and carbonate. Based on major macroscopic sediment features eight major lacustrine sediment types (~900 layer) were differentiated and separated from the volcaniclastic deposits (300 layer). Impressive color transitions and a repetitive pattern of similar lithological successions occur throughout the

    Turkey knockdown was diagnosed in three of five flocks of hen turkeys on a single farm within a 12-mo period. The age of birds in the flocks affected ranged from 6 wk 2 days to 7 wk 4 days. The attack rate ranged from 0.02% to 0.30% with a case fatality rate in affected birds ranging from 0 to 74%. The diagnosis was made on the basis of clinical signs and histopathologic lesions associated with knockdown. The feed in all flocks contained bacitracin methylene disalicylate and monensin (Coban). Affected birds were recumbent, demonstrated paresis, and were unable to vocalize. Postmortem examination revealed few significant lesions although pallor of the adductor muscles and petechiation in adductor and gastrocnemius muscles were noted. Birds that had been recumbent for extended periods were severely dehydrated. Consistent microscopic lesions included degeneration, necrosis, and regeneration of adductor, gastrocnemius, and abdominal muscles. No lesion in cardiac tissue was noted. Results of our investigation indicated that changes in water consumption, vitamin E status, and brooder to finisher movement correlated with the occurrence of knockdown. Turkey knockdown was defined in 1993 as any condition identified in a turkey flock that has affected the neuromuscular system to a degree that a turkey is unable to walk or stand. This definition was later modified to...neuromuscular or skeletal systems to a degree that a turkey is unable to walk or stand properly. Knockdown may be associated with numerous feed, management, or disease factors alone or in combination. Dosage of monensin, feed restriction/gorging, water restriction, heat stress, copper, mycotoxins, sodium chloride in feed, and sulfa drugs have all been suggested as contributing factors; however, laboratory studies to duplicate this have not been successful. This report presents observations from a single farm at which three of five hen flocks in a single year experienced knockdown. When a flock was reported as

This article argues that Turkey could regain initiative without sacrificing its national interests by withdrawing its military forces stationed on the island and organizing a referendum on the future of the TRNC. The removal of the military would terminate Turkey's status as an occupying power, while a referendum could add legitimacy to the TRNC and put pressure on Cyprus.

    affected by humans (Sanderson et al., 2002; Braje&Erlandson, 2014). The area left in its natural state corresponds to only 15%. Due to population increase, agricultural areas shrinked, forests were destroyed, and pastures declined in size. More chemical fertilizers and agricultural pesticides were used in order to obtain more products. A greater number of machines were employed in agriculture, which led to a rise in the number of products. The human pressure on the environment in Anatolia dates back to thousands of years. Nomadic peoples on these lands have settled in the last 200 years due to settlement policies (Cürebal et al., 2015). This process saw the establishment of villages in higher and inclined areas as a result of the effects of the nomadic culture of Turkomans and other people in Anatolia. Forests in the inclined areas around these villages were destroyed and turned into agricultural areas. Machines, fertilizers, and pesticides were utilized in agricultural activities in order to produce more crops. This transformation led to an increased erosion effect, deterioration of soil, agricultural and environmental pollution (Chin et al., 2013; Hoang et al., 2014; Matteo et al., 2014). The change caused by industrialization gained ground in the 1950s in Turkey. In particular, migration from rural areas to cities gaining pace after the World War II brought about an increased human pressure in and around big cities. Areas around the cities became centers of attraction for many people. Plains around settlement areas were opened to settlement, and most industrial facilities were established there. As a consequence, first class agricultural areas were lost. Settlements and industrial areas generated large amounts of solid and liquid waste. Uncontrolled discharge of liquid waste and intensely stored solid waste caused the physical and chemical pollution of rivers, lakes, and seas to increase in Turkey and other parts of the world (Andersson et al., 2006; Steffen et al

    Full Text Available Corporate governance is important and vital for big businesses as well as small and medium sized enterprises (SME. Executives can find low-cost resources by implementing fairness, transparency, accountability and responsibility principles in their companies and can grow rapidly in the sector in accordance with the cost advantage in hand. The biggest drawback of the SMEs is that they cannot use these advantages because they are mostly built up as Family Corporation. The firms in Turkey are mostly be made up off SMEs. Since the current structure of the SMEs are not suitable in terms of corporate governance and the idea that the principles of corporate governance are hard to be used by SMEs, constitutes the main problem of the research. The data that has been collected analyzed using SPSS and it has been concluded that SME’s in the region are not the sufficient level for corporate governance.

    Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remains from 6th-8th century Northern Italy, 7th-11th century Hungary, 8th-9th century Austria, the Slavic Greater Moravian Empire of the 9th-10th century and 8th-10th century Byzantine samples from Northern Anatolia. These data were analyzed alongside findings published by others. M. leprae is an obligate human pathogen that has undergone an evolutionary bottleneck followed by clonal expansion. Therefore M. leprae genotypes and sub-genotypes give information about the human populations they have infected and their migration. Although data are limited, genotyping demonstrates that historical M. leprae from Byzantine Anatolia, Eastern and Central Europe resembles modern strains in Asia Minor rather than the recently characterized historical strains from North West Europe. The westward migration of peoples from Central Asia in the first millennium may have introduced different M. leprae strains into medieval Europe and certainly would have facilitated the spread of any existing leprosy. The subsequent decline of M. leprae in Europe may be due to increased host resistance. However, molecular evidence of historical leprosy and tuberculosis co-infections suggests that death from tuberculosis in leprosy patients was also a factor.

    The Aegean region including western Turkey, mainland Greece, and the Hellenic Arc is the most seismological and geodynamical active domain in the Alpine Himalayan Belt. In this study, we processed 3 years of survey-mode GPS data and present the analysis of a combination of geodetic and seismological data around Izmir, which is the third most populated city in Turkey. The velocities obtained from 15 sites vary between 25 mm/yr and 28 mm/yr relative to the Eurasian plate. The power law exponent of earthquake size distribution (b-value) ranges from 0.8 to 2.8 in the Izmir region between 26.2°E and 27.2°E. The lowest b-value zones are found along Karaburun Fault (b = 0.8) and, between Seferihisar and Tuzla Faults (b = 0.8). A localized stress concentration is expected from numerical models of seismicity along geometrical locked fault patches. Therefore, areas with lowest b-values are considered to be the most likely location for a strong earthquake, a prediction that is confirmed by the 2005 Mw = 5.9 Seferihisar earthquake sequences, with epicentres located to the south of the Karaburun Fault. The north-south extension of the Izmir area is corroborated by extension rates up to 140 nanostrain/yr as obtained from our GPS data. We combined the 3-year GPS velocity field with the published velocity field to determine the strain rate pattern in the area. The spatial distribution of b-value reflects the normal background due to the tectonic framework and is corroborated by the geodetic data. b-Values correlate with strain pattern. This relationship suggests that decrease of b-values signifies accumulating strain.

  19. Quality Assurance: Strategic Choices for Higher Education in Turkey

    Mahmut ÖZER

    2011-01-01

    Full Text Available As the number of students and higher education institutions in the world increases and there is a growing difficulty in financing the higher education systems, decision-makers have begun to show more interest in quality assurance. As quality assurance is given special attention in European countries, developing countries such as Turkey are interested in importing quality assurance systems. It is not possible to set quality assurance without sensitivity toward quality and without having quality as a cultural practice. The most likely encountered quality assurance approach in the world is that the higher education institution itself is responsible for its quality. In addition, external quality assurance procedures used are based on (academic peer review rather than on bureaucratic evaluations. Moreover, there is a lively debate across the world regarding the bureaucratic regulations of the quality assurance agencies and institutions that restrict the autonomy of higher education institutions. Without taking into consideration of the existing centralized structure of the higher education system in Turkey, of meeting social demands for the higher education, and of current higher education enrollment rates, the possible establishment of a quality assurance mechanism that may have sanctions on universities in Turkey is a threat to already limited autonomy of universities and is having a risk of additional bureaucratic burden. By laying out the roles and responsibilities of Turkish Council of Higher Education, the government and universities, this article discusses policies that should be adopted regarding the quality assurance.

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    Full Text Available Zoonoses and zoonotic diseases are becoming more common and they are now receiving increased attention across the world. Zoonotic parasites are found in a wide variety of protozoa, cestodes, nematodes, trematodes and arthropods worldwide and many zoonotic parasites have assumed an important role. The importance of some parasitic zoonoses has increased in recent years due to the fact that they can be agents of opportunistic infections. Although a number of zoonotic parasites are often found and do cause serious illnesses in Turkey, some are more common and these diseases are more important as they cause serious public health problems, such as leishmaniasis, toxoplasmosis, cryptosporidiosis, echinococcosis, trichinellosis and toxocariasis. Information on these zoonotic diseases is provided here as these are the most important zoonotic parasitic diseases in Turkey.

    Full Text Available L’énergie en Turquie est aujourd’hui fournie par l’énergie fossile. De plus, la Turquie est dépendante de l’extérieur en matière d’énergie pour son économie et les secteurs divers qui en ont besoin. En Turquie, parallèlement aux informations ci-dessus, 83% de l’électricité de l’an 2008 provient des sources d’énergie fossile. Les perspectives d'avenir prévoient que la demande d’énergie de la Turquie augmentera et l’effet naturel de cette croissance sera l’augmentation du taux de dépendance énergétique à l'égard des autres pays. Les travaux effectués démontrent que, parmi les sources d’énergies renouvelables de la Turquie, le pouvoir hydraulique et le potentiel d’énergie éolienne sont les plus importants et que chacune de ces deux sources ont des potentiels techniques pour la production de l’électricité. La multiplication des centrales éoliennes au cours de ces dernières années est à relier à des facteurs comme la préparation de l’Atlas d’Energie Eolienne Turc, la disposition des lois afin d’aider les entrepreneurs du secteur privé et l’augmentation des prix du pétrole. Les centrales éoliennes fonctionneront dans la région de Marmara, la région d’Egée et dans la partie de méditerranée orientale de la Turquie où se manifestent plus souvent les vents violents. Il est probable que quelques autres centrales seront construites dans d'autres régions que celles citées précédemment.Covering its energy requirement from fossil energy sources for the most part, Turkey relies on outside sources to procure energy required for its economy and different sectors. Similarly, Turkey had produced 83 pct of the overall electricity in 2008 out of fossil energy sources. Future projectors indicate that the energy requirement of our country would augment and foreign-dependency in energy would thus increase accordingly.  The on-going studies state that especially hydraulic power and wind

    The Anatolian 'plate' is being extruded westward relative to the Eurasia along two major tectonic structures, the North Anatolian and the East Anatolian shear zones, respectively making its northern and eastern boundaries. Although the main deformation is localized along these two structures, there is remarkable intra-plate deformation within Anatolia, especially which are characterized by NE-striking sinistral and NW-striking dextral strike-slip faults (Şengör et al. 1985). The Malatya-Ovacık Fault Zone (MOFZ) and its northeastern member, the Ovacık Fault (OF), is a one of the NE-striking sinistral strike slip faults in the central 'ova' neotectonic province of Anatolia, located close to its eastern boundary. Although this fault zone is claimed to be an inactive structure in some studies, the recent GPS measurements (Aktuǧ et al., 2013) and microseismic activity (AFAD, 2013) strongly suggest the opposite. In order to understand rates and patterns of vertical ground motions along the OF, we studied the certain morphometric analyses such as hypsometric curves and integrals, longitudinal channel profiles, and asymmetry of drainage basins. The Karasu (Euphrates) and Munzur rivers form the main drainage systems of the study area. We extracted all drainage network from SRTM-based Digital Elevation Model with 30 m ground pixel resolution and totally identified 40 sub-drainage basins, which are inhomogeneously distributed to the north and to the south of the OF. Most of these basins show strong asymmetry, which are mainly tilted to SW. The asymmetry relatively decreases from NE to SW in general. The only exception is at the margins of the Ovacık Basin (OB), where almost the highest asymmetry values were calculated. On the other hand, the characteristics of hypsometric curves and the calculated hypsometric integrals do not show the similar systematic spatial pattern. The hypsometric curves with convex-shaped geometry, naturally indicating relatively young morphology

    The mussels (Mytilus galloprovincialis) have been evaluated for their bioavailability as biomonitors of trace and toxic elements in coastal water of western Anatolia. The levels of Fe, Cu, Zn, Pb, Br and Sr in the edible part of mussels were determined using X-ray fluorescence method during the period of September 1999-July 2000. Distribution of {sup 210}Po and {sup 210}Pb activities were measured by radiometric methods and their ratios were calculated. The activity concentrations of {sup 210}Po and {sup 210}Pb were found to vary between 52{+-}6-1344{+-}108 and 6{+-}2-167{+-}10 Bq kg{sup -1} dry wt, respectively. The highest values for {sup 210}Po and {sup 210}Pb were measured in Foca mussels and also observed the highest Fe, Zn and Br concentrations in the same species. {sup 210}Po/{sup 210}Pb activity ratio were derived as between 3.1 and 25.0.

    Women in Turkey have many social, cultural and economical problems. Women with leprosy have problems in common with other women as well as those related to physical and social consequences of leprosy. There are 2,414 patients with leprosy in Turkey, registered to Istanbul Leprosy Hospital and 829 of them are females. The mean age and duration of disease of our female leprosy patients are high. Most women with leprosy were born in eastern part of Turkey where prevalence of leprosy is higher and most have moved to western regions. The proportion of women who have some kind of social security is very low. Their economic status is also not good and 79% of patients had stigma about their disease. Three fourths of these cases have been hospitalized some time, for different reasons. Most of them (97.2%) have inactive disease at present. Disability degrees of patients are high. Patients with disability degrees over one constitute 54% of total for eyes, 55% for hands and 51% for feet. High percentage of multibacillary form and long duration of disease, delayed diagnosis, insufficient self-care of patients due to low socio-economic and cultural status and failure of health personnel to control patients periodically may be among the reasons for such high ratios of moderate and severe disabilities. In the light of the data obtained in our study, some measures to alleviate the problems of patients resulting from their socio-economic, cultural and social status have been suggested.

    In the present study we evaluated the effects of iodine intake on the prevalence of thyroid dysfunction, autoimmunity, and goiter in two regions with different iodine status after two years of iodization in Turkey. In total 1733 adolescent subjects were enrolled into the study (993 from an iodine-sufficient area--the Eastern Black Sea Region (group 1) and 740 from an iodine-deficient area--Middle Anatolia (group 2)). We measured free thyroxine (FT(4)), thyrotropin (TSH), antithyroid peroxidase antibodies (Anti-TPO), antithyroglobulin antibodies (Anti-Tg), and urinary iodine (UI), and examined the thyroid gland by ultrasound. Median urinary iodine excretion was found to be significantly different in group 1 and group 2 (139 micro/l vs 61micro/l, p 0.05). The percentage of anti-Tg positive subjects was found to be 17.6% in group 1 and 6.4% in group 2; that of anti-TPO positive subjects was 4.3% in group 1 and 1.5% in group 2. The prevalence of antithyroid antibody (anti-Tg and/or anti-TPO) positivity was significantly higher in group 1 than in group 2 (18.52% vs 6.62%; p iodine supplementation in Turkey has resulted in the elimination of iodine deficiency in the Eastern Black Sea Region, and this has been accompanied by an increase in the prevalence of autoimmune thyroiditis and thyroid dysfunction.

    The Kula volcanic field is the youngest volcanic province in western Anatolia and covers an area of about 600 km2 around the town Kula (Richardson-Bunbury, 1996). Its alkali basalts formed by melting of an isotopically depleted mantle in a region of long-lived continental extension and asthenospheric upwelling (Prelevic et al., 2012). Based on morphological criteria and 40Ar/39Ar dating, four phases of Quaternary activity have been distinguished in the Kula volcanic field (Richardson-Bunbury, 1996; Westaway et al., 2006). The youngest lava flows are thought to be Holocene in age, but so far only one sample from this group was dated by 40Ar/39Ar at 7±2 ka (Westaway et al., 2006). In this study, we analysed cosmogenic 3He in olivine phenocrysts from three basalt flows and one cinder cone to resolve the Holocene history of volcanic eruptions in more detail. In addition, we applied 10Be exposure dating to two quartz-bearing xenoliths found at the surface of one flow and at the top of one cinder cone. The exposure ages fall in the range between ~500 and ~3000 years, demonstrating that the youngest volcanic activity is Late Holocene in age and therefore distinctly younger than previously envisaged. Our results show that the Late Holocene lava flows are not coeval but formed over a period of a few thousand years. We conclude that surface exposure dating of very young volcanic rocks provides a powerful alternative to 40Ar/39Ar dating. References Prelevic, D., Akal, C.

    The objective of this study was to determine Salmonella levels (presence and numbers) in turkey drumstick bone, spleen, and neck skin samples in relation to Salmonella contamination levels in ground turkey at the flock level. Over a 10-month period, a total of 300 samples of each turkey part (i.e., neck skin, spleen, and drumstick) from 20 flocks were collected at a commercial turkey processing plant after the evisceration step. Turkey flocks included in this study were classified as "targeted" and "nontargeted" based on the company's historical ground turkey contamination data. A flock that originated from a turkey farm that had previously produced one or more flocks with ≥20% Salmonella prevalence in ground turkey was labeled as a targeted flock (n = 13). The remaining seven flocks with Salmonella presence and numbers by using most-probable-number and selective enrichment methods. Further genotypic analysis (pulsed-field gel electrophoresis) of the isolates was performed. Ground turkey samples were collected and analyzed for Salmonella levels by the cooperating turkey company. The outside surface of bone and spleen were sterilized prior to Salmonella analysis. The overall Salmonella prevalence in neck skin, drumstick bone, spleen, and ground turkey samples was 42.0, 9.3, 6.7, and 14.5%, respectively. Salmonella prevalence in neck skin, spleen, drumstick bone, and ground turkey from the targeted flocks was significantly (P Salmonella presence in neck skin (when most probable numbers were ≥2 log) and Salmonella-positive ground turkey lot. Based on our findings, Salmonella was detected internally in drumstick bones and spleens at low levels, whereas Salmonella presence at higher levels in neck skin may indicate a flock with greater potential for Salmonella contamination of ground turkey.

    During the Middle through Late Miocene, over 1200 m of clastics, carbonates and evaporites accumulated in the depositional basin situated in northwestern Ankara province of Central Anatolia. Detailed stratigraphic and sedimentological analyses of the exposed sequence exhibits three major facies: (1) lower alluvial, (2) upper alluvial, and (3) lacustrine. The lower alluvial facies consists primarily of volcaniclastic debris-flow, boulder and channel conglomerate, sandstone, siltstone, mudstone and two lignite horizons. These rock assemblages were deposited in alluvial fans and a braided-river system. The lower and upper lignite seams were laid down in swamps and lake-margin mud-flat environments associated with this river system. The upper alluvial facies is characterized by red conglomerate, fine-grained and cross-bedded sandstone, mudstone and calcareous mudstone units. The dominant depositional environments are interpreted to be alluvial fan, braided-river, and mud-flat. The base of the lacustrine deposits interfingers with the lower alluvial facies and consists of dolomitic claystone, bituminous shale, trona and intraformational conglomerate lithofacies. The sedimentary features of the dolomitic claystone and trona lithofacies suggest deposition in a playa-lake type environment. The bituminous shale is a transgressive deposit laid down in a shallow, but expanded lake environment. Sedimentological and structural characteristics of the intraformational conglomerate lithofacies indicate synsedimentary tectonism, intrabasinal erosion, redeposition and sediment selection toward the deposition centre of the lake environment. The green claystone lithofacies has three units: (a) the claystone-bedded chert-analcitized tuff alternation and siliceous carbonate lithofacies of the lacustrine system, deposited in a perennial lake environment; (b) montmorillonitic olive-green claystone containing mud-cracks, ripple mark and desiccation cracks filled by gypsum, deposited in a

    A cDNA clone homologous to the fibroblast growth factor homologous factor (FHF-2) was isolated and sequenced from the turkey (Meleagris gallopavo). The DNA sequence of the turkey was almost identical to that of the chicken (99% similarity) differing at only 8 of 770 nucleotides in the coding region resulting in a single amino acid difference between these poultry species. The 3'UTR of the turkey FHF-2 gene was 445 nucleotides in length and included an imperfect CT microsatellite (ms) repeat. The sequence of the 3'UTR was amplified from genomic DNA of the chicken and found to be highly conserved differing at only three nucleotides when compared to the turkey. Length of the CT repeat was indifferent in a sample of 52 turkeys (monomorphic) however, the number of CT repeats was greater in the turkey than in the chicken. No inter-individual polymorphism was detected in multiple sequences of the 3'UTR of the FHF-2 gene in the turkey. Based on comparison of the turkey and chicken sequences, the mutation rate for coding and associated non-coding (3'UTR) regions of FHF-2 are approximately equal.

    2016-02-01

    Full Text Available Recent large-scale natural gas discoveries in East Mediterranean have drawn attention to the region. The discoveries caused both hope and tension in the region. As stated, the new resources may serve as a new hope for all relevant parties as well as the region if managed in a collaborative and conciliatory way. Energy may be a remedy to Cyprus' financial predicament, initiate a process for resolving differences between Turkey and Cyprus, normalize Israel-Turkey relations and so on. On the contrary, adopting unilateral and uncooperative approach may aggravate the tension and undermine regional stability and security. In this sense, the role of energy in generating hope or tension is dependent on the approaches of related parties. The article will analyze Turkey's attitude in East Mediterranean case in terms of possible negative and positive implications for Turkey in the energy field. The article examines Turkey's position and the reasons behind its stance in the East Mediterranean case. Considering Turkey's energy profile and energy policy goals, the article argues that the newly found hydrocarbons may bring in more stakes for Turkey if Turkey adopts a cooperative approach in this case.

    The history of the Late Cenozoic stress regime was determined for an area between the gulfs of Fethiye and Antalya. Fault kinematic analysis and inversion of focal mechanisms of shallow earthquakes reveal significant evolution of the regional stress regime in SW Anatolia, i.e., the area of interaction between the Hellenic and Cyprus arcs, from the Mio-Pliocene to the present time. Fault kinematic analysis yields two different normal faulting stress regimes along the southwestern part of Fethiye-Burdur Fault zone, e.g., in and around Çameli Basin (Zone A1) and two different strike-slip to normal faulting stress regimes characterized by a roughly orthogonal set of extensional axes between Fethiye and Demre (Zone B) with an older NW-SE σ3 axis for Mio-Pliocene and a younger NE-SW σ3 axis for Plio-Quaternary time. Inversion of focal mechanisms of the earthquakes occurring in Zone A1 provides an extensional stress state with approximately N-S σ3 axis. Inversion of those occurring in Zone B, south of Zone A1, yields a dominantly strike-slip stress state with a NE-SW σ3 axis and a NW-SE σ1 axis respectively. The inversion slip vectors from fault planes yield a consistent normal faulting stress regime in Burdur Basin and its surroundings (i.e., along the northeastern part of Fethiye-Burdur Fault Zone, (Zone A2)) during Plio-Quaternary, continuing into recent time as indicated by earthquake focal mechanism inversions. Both states have a consistent NW-SE σ3 axis. Fault kinematic analysis indicates NW-SE extension acting in Zone C (subarea between Demre and Antalya), south of Zone A2, during Mio-Pliocene time. The inversion of focal mechanisms yields normal faulting also characterized by a consistent NW-SE σ3 axis. The nearly orthogonal extensional stress regimes (NW-SE and NE-SW) obtained by inversion of both measured and seismic faults seem to have been acting contemporaneously with each other at different intensities from the Mio-Pliocene onwards in SW Turkey.

    Liver transplantation is the definitive treatment for end-stage liver diseases. The first successful liver transplant was performed in the United States by Thomas Starzl in 1967. The first successful solid organ transplant in Turkey was a living-related kidney transplant performed by Dr. Haberal in 1975. After much effort by Dr. Haberal, the Turkish parliament enacted a law about organ transplantation in 1979. After clinical and experimental studies, the first liver transplant in Turkey was performed by Dr. Haberal in 1988. The first successful partial living-donor liver transplant in children in Turkey was performed by the same team on March 15, 1990. On April 24, 1990, the first living-donor liver transplant was performed on a child in Turkey using a left lateral segment by Dr. Haberal and coworkers. On May 16, 1992, Dr. Haberal performed a simultaneous living-donor liver and kidney transplantation to an adult from the same donor. There currently are 30 liver transplantation centers in Turkey. According to data from the Ministry of Health, there presently are 2065 patients in Turkey who are waiting for a liver transplantation. From January 2002 to June 2013, there were 6091 liver transplants performed in Turkey (4020 living-donor [66% ] and 2071 deceased donor liver transplants [34% ]). From January 2011 to June 2013, there were 2514 patients who had liver transplants in Turkey, and 437 patients (17%) died. The number of liver transplants per year in Turkey reached 1000 transplants in 2012 and more than 1150 transplants in 2013 (15.1/million/y). Therefore, Turkey has one of the highest volumes of liver transplantation per population worldwide, with 90% survival within 1 year after transplantation.

    Full Text Available Autospy is an important tool for the development of pathology as a science. In western civilisation dissection of human body became widespread with Renaissance, in contrast in the Ottoman Empire first dissection was not performed until the 19th century. Mustafa Behçet Efendi, head physician of the Empire, was one of the Ottoman physician who suggested the importance of dissection in the medical education. The first dissection was however performed by Charles Ambroise Bernard, a foreign physician who had been invited to help establishing a new medical school; “Mekteb-i Tıbbiye-i Adliye-i Şâhâne”, in 1843. The first modern medical schools called “Tıphane” and “Cerrahhane-i Amire” which were founded in 1827, did not have pathology courses. Pathology courses began in “Mekteb-i Tıbbiye-i Adliyei Şâhâne”. Dr. Hamdi Suat (Aknar, educated in anatomic pathology in Germany, was the first pathologist who established the modern pathology in Turkey in “İstanbul Darülfünun” medical school. In 1933 “Darülfünün” was closed and İstanbul University was built and the “University Reform Commission” invited many scientists escaping from Nazi government to study in İstanbul University. Dr. Philipp Schwartz had an important role both in the invitation of these scientists and establishment of the pathology department in İstanbul University. Practical courses were increased, clinicopathologic courses were organized for the first time and a lot of autopsies were performed, as high as 1000 autopsy per year, by Dr. Philipp Schwartz. More progress has takes place in Turkey over the years since pathology was first established. Today Turkey has many pathology departments which keep up with the worldwide advances in the field.

Gram staining and culture were performed in 51 patients. Gram-positive bacilli were detected in 17 patients (33.3% by gram smear. Bacillus anthracis bacilli were produced in 11 patients (21.5% in cultures test. The lesions were mostly seen on the left hand (30.2%. Penicillin was most frequently preferred in treatment of CA (87.3%. Conclusion: CA is still endemic in Eastern Anatolia and continues to increase in recent years. Women living in the villages in which income is obtained from buying and selling of animals constitute the most important risk group. Preventive actions such as training of the risky society, vaccination of animals, and obstructing of illegal animal entries across the border, will reduce the incidence of CA.

    especially in the dominant of military organization in Turkey’s great national struggle. During the terrible time of Anatolia in the national struggle, he worked tirelessly with Turkish spirit behind the front. In Kastamonu, Adana and their regions, and in the Battles of Sakarya and İnönü, he kept the organization and the military training of the recruits up, and displayed a great courage in preparing everyone for the defense of country. Before driving the Greek forces into the sea in Izmir, and when the Turkish army was nearly collapsing and it could not even defend itself, he collected the army, and made it ready for the war. In fact, in Anatolia, especially in Kastamonu and its region, the people even did not know the concept of organization. Therefore, he organized them and got people to make military training, who were unable to keep a weapon. In the most dangerous times of Anatolia, Muhittin Pasha tried and worked non-stop to train in the front, defend high attack of enemy power, and drive the enemy forces into the sea. The people of Anatolia greatly respected this man, who had brought them a great victory. The second activity of Muhittin, who had a high-level military and administrative talent, was in Adana. He was the representative of Turkey in the commission founded in Beirut for the act of Turkey-Syrian Customs Agreement which was the requirement of Article 11th of Cilicia Agreement between Turkey and France.

    Researches in the field of pottery production technology in ancient times, done in different settlements during the same period, may contribute to know relationships established within the different cultural communities. In ancient times, Anatolia (Asia Minor) was the crossroads of ancient civilizations. There are several ancient settlements and artifacts belonging to Hellenistic culture (330-30 BC). West Slope wares from Dorylaion (Eski ehir/Turkey) excavations are the main Hellenistic culture findings. In this study, different analytical techniques were employed for the characterization of these findings in order to enlighten the pottery production technology. Wavelength dispersive X-ray fluorescence (WDXRF) and X-ray diffraction (XRD) were employed to study the chemical and mineralogical composition of the bodies, respectively. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDX) were also performed for the microstructural and microchemical characterization of body and slip layers of the selected potsherds. The raw materials used, firing temperatures and atmosphere and related microstructural characteristics were discussed. (Author) 22 refs.

    The region covering Southeastern Anatolia takes place in upper Mesopotamia, so it has numerous cultural heritages due to its witness to various social movements of different civilizations in ancient times. Kuruki Mound is located on the junction point of Tigris River and Batman Creek, near Oymatas village which is almost 15 km to Batman, Turkey. The mound is dated back to Late Chalcolithic. Archaeological excavations are carried out on two hills named as “Kuriki Mound-1” and “Kuriki Mound-2” in which 4-layer and 2-layer settlements have been revealed, respectively. This region will be left under the water by the reservoir lake of Ilısu Dam when its construction is completed. Thus, characterization of ancient materials such as potsherds, metals and skeleton ruins should be rapidly done. In this study, 12 potsherds excavated from Layer-1 (the first settlement layer after the surface) in Kuriki Mound-2 were investigated by FT-IR spectrometry. Energy dispersive X-ray fluorescence (EDXRF) and X-ray diffraction (XRD) analyses were used as complementary techniques in order to expose chemical and mineralogical/phase contents, respectively. Obtained results showed that the potteries have been produced with calcareous clays and they include moderate amounts of MgO, K2O, Na2O and Fe2O3 in this context. Additionally, high temperature phases have also been detected with XRD analyses in some samples.

    Fifteen Lateglacial to Holocene rhyolitic, dominantly primary tephra layers piston-cored and drilled (ICDP Paleovan drilling project) in western Lake Van (eastern Anatolia, Turkey) were precisely correlated to either of the two adjacent and active large volcanoes Nemrut and Süphan based on shard textures, mineralogy and mineral and glass compositions. The young peralkaline (comenditic to pantelleritic) primary rhyolitic Nemrut tephras are characterized by anorthoclase, hedenbergitic to augitic clinopyroxene, fayalitic olivine, minor quartz, and rare accessory chevkinite and zircon. Phenocrysts in subalkaline primary rhyolitic Süphan tephras are chiefly oligoclase-labradorite, with minor K-rich sanidine in some, biotite, amphibole, hypersthene, rare augitic clinopyroxene, relatively common allanite and rare zircon. Two contrasting explosive eruptive modes are distinguished from each other: episodic (Süphan) and periodic (Nemrut). The Lateglacial Süphan tephra swarm covers a short time interval of ca. 338 years between ca. 13,078 vy BP and 12,740 vy BP, eruptions having occurred statistically every ca. 42 years with especially short intervals between V-11 (reworked) and V-14. Causes for the strongly episodic Süphan explosive behavior might include seismic triggering of a volcano-magma system unable to erupt explosively without the benefit of external triggering, as reflected in pervasive faulting preceding the Süphan tephra swarm. Seismic triggering may have caused the rise of more mafic ("trachyandesitic") parent magma, heating near-surface pockets of highly evolved magma - that might have formed silicic domes during this stage of volcano evolution - resulting in ascent and finally explosive fragmentation of magma essentially by external factors, probably significantly enhanced by magma-water/ice interaction. Explosive eruptions of the Nemrut volcano system, interpreted to be underlain by a large fractionating magma reservoir, follow a more periodic mode of (a

    Full Text Available All countries strive for a capable national defense supported by a strong national defense industry. Supporting national defense with imported defense systems has many limitations and risks because the terms of arms trade agreements between countries may easily be influenced by the political climate of the signatories. As a result, establishing an independent national defense requires a strong national defense industry. Furthermore, exporting defense systems may be an important source of national income. National defense industries mostly consist of large-scale defense firms that have the resources required for big defense contracts. However, small to medium enterprises (SMEs do not have the necessary resources, therefore they are at a disadvantage. To overcome this handicap and be part of the business, defense industry clusters mostly consisting of SMEs are being established. Provided that there is good national planning and support in this area, defense clusters consisting of SMEs may play a significant role in industry. SMEs have a chance to offer specialized services, special or customized products when needed. As a result, large defense firms subcontract certain portions of defense projects to SMEs. Since 2010, Turkey has shown signs of continuous improvement in defense industry clustering. In parallel with these developments, this study discusses the importance of clustering in the defense industry, briefly presents the state of the Turkish defense industry as highlighted by national statistics, and presents the current status of defense clusters in Turkey. The novelty of this article consists in its assessment of Turkish defense clusters.

Learning environment is organized to gain collaborative experience to students and to provide project-based learning of students in Denmark. So there is a seating arrangement for team-work. The classes are usually organized according to sequential column technique in Turkey. Evaluation is also provided the future planning of education as well as sharing with the family about student’s learning outcomes in Denmark. At the end of 9 and 10 class, Folkeskole students enter for school-leaving examinations. Students have an exam each course (except electives courses at the end of the period at the level of the class passing rather than school- leaving examinations. Results and Discussion: Education is compulsory for everyone between the ages of 6-16 in Denmark since 2009, compulsory for everyone between the ages 6-14 in Turkey since 1997. At the same time today one- year pre-school education which is free is compulsory since August 2009 in Denmark; it is also started the implementation of compulsory pre-school in several pilot cities in Turkey. This is a positive development for both countries. Because this period consists time that is strong the individual’s learning ability. Education is a local structure in Denmark. It is planned and carried out centrally in Turkey. As of today conditions, it is observed that this situation creates difficulties in solving problems relating to education and uncover view which need to go decentralization in education. In this context, it can be done required studies for localization and be taken model the developed countries. In Denmark and Turkey curriculum is determined at the national level by the Ministry of Education. Denmark Education System carries local impacts as different from Turkey in terms of issues such as the decisions taken in the field of education in Denmark, the school system

    Serum samples and tracheal cultures were collected from eastern wild turkeys (Meleagris gallopavo sylvestris) trapped for relocation in South Carolina (USA) during 1985 to 1990. Sera were tested for Mycoplasma gallisepticum and M. synoviae by the rapid plate agglutination and hemagglutination inhibition tests and were found to be negative. Tracheal cultures were negative for all pathogenic Mycoplasma spp., including M. gallisepticum, M. synoviae, M. meleagridis, and M. iowae. However, M. gallopavonis was isolated from every group of wild turkeys tested in 1986 to 1990. These data suggest that M. gallopavonis, which is generally considered nonpathogenic, may be a common microorganism in eastern wild turkeys.

  15. Record of high-pressure overprint in metamorphic soles of the Tavşanli zone, Western Anatolia

    Large obducted ophiolites correspond to the emplacement of dense oceanic lithosphere on top of a continent and thereby provide insights into rheological and thermal coupling between plates or fluid budgets. Obducted ophiolites thrust onto the continental margin of the Anatolide-Tauride block (Western Anatolia, south of the Izmir-Ankara suture zone) are dated through their metamorphic sole at ca. 90-95Ma and derive from the same intra-oceanic Neotethyan subduction. We herein focus on the metamorphic soles of the Tavşanlı zone, which show a variable high-pressure low-temperature (HP-LT) overprint of the initial amphibolitic metamorphic conditions (Önen & Hall, 1993; Dilek & Whitney, 1997; Okay et al, 1998). Systematic sampling was done in both the already studied areas as well as new locations. PT conditions were estimated at 8 kbar and 700°C for the amphibolitic stage with the assemblage hornblende + plagioclase ± garnet ± epidote. The HP-LT metamorphic overprint reached incipient blueschist to blueschist facies PT conditions. Development of the characteristic assemblage glaucophane + lawsonite yields PT estimates of >6-7 kbar and 300°C. The high-pressure stage is similar to the one observed for the underlying accretionary-complex unit of the Tavşanlı zone (Plunder et al, this meeting). This HP overprint was not observed in other obduction contexts such as Oman or New Caledonia but was documented in Fransciscan Complex amphibolites (Wakayabashi, 1990). The record of two metamorphic events can be understood as: (1) rapid cooling of the subduction zone after initiation and the exhumation of the metamorphic sole; (2) reburial after or during exhumation of the amphibolite initially welded at the base of the ophiolite. Several observations (i.e., lack of tectonic contact between the ophiolitic body and the metamorphic sole, PT estimates,...) point to cooling as the most likely hypothesis. Metamorphic soles allow to highlight: (1) the dynamics of obducted

    Full Text Available A total of 572 California Mastitis Test (CMT positive milk samples were collected from 423 lactating cows on 18 private farms in the Middle Western Anatolia. Coagulase–negative staphylococci colonies and CNS species identification was performed based on conventional biochemical techniques and using the API Staph test. Slime production was detected by Congo Red Agar (CRA method. The antibiotic susceptibility was determined according to the National Committee for Clinical Laboratory Standards guidelines (NCCLS. A total of 67 (11.7% coagulase-negative staphylococci (CNS were isolated from CMT positive milk samples. In total, 11 CNS species: S. epidermidis (n=18, S. simulans (n=14, S. warneri (n=10, S. hominis (n=5, S. chromogenes (n=4, S. caprae (n=4, S. xylosus (n=3, S. haemolyticus (n=3, S. hyicus (n=3, S. cohnii (n=2, and S. capitis (n=1 were identified. The most commonly identified CNS species were Staphylococcus epidermidis (26.8% and Staphylococcus simulans (20.8% followed by Staphylococcus warneri (14.9%. Out of 67 CNS isolates, slime production was found in 37 (55.2% CNS strains. CNS isolates were the most resistance to trimethoprim+sulphamethoxazole (76.2%, erythromycin (73.2%, oxacillin and ampicillin (70.2% followed by penicillin (58.3%, gentamicin (53.8%, tetracycline (52.3%, vancomycin (51.8%, ciprofloxacin (26.9%, cefoxitim (23.9%, and cephalothin (13.5%.

    The construction of a large open air theatre having with an audience capacity of 7,000 is planned at the Beytepe Campus of Hacettepe University located near Ankara, Turkey, in the heart of Anatolia. The foundation of the open air theatre is composed of weak and heavily jointed Ankara Greywacke. An estimation of the strength and deformation of the Ankara Greywacke was required for assessments of short- and long-term stability. Accordingly, rock mass characterization of the Ankara Greywacke was investigated in detail by scan-line surveys and back-analyses of in situ tests performed on the excavated surface of the rock mass. The final version of the Hoek and Brown Criterion (Hoek et al., In: Proceedings of the north American rock mechanics society meeting, Toronto, Canada, pp 1 6, 2002) together with and improvements proposed by Sonmez and Gokceoglu (Int J Rock Mech Min Sci, 43:671 676, 2006) were considered together for the back analyses of small slope benches subjected to plate loading test loaded to failure. In addition, the plate loading test data were used with some well-known empirical equations for predicting of deformation modulus of rock masses to calculate ranges of values of the Geological Strength Index (GSI) The static and pseudostatic slope stabilities of the audience seating structures to be supported by benches excavated into the rock were also analyzed. The stability assessments revealed the unlikelihood of large rock mass failures for the short-term construction stages or for the long-term, as-constructed conditions under static or pseudo-static conditions. Additionally, the analyses showed that there was no need for anchors between the concrete seating structures and greywacke rock mass.

    In southwest Asia, Turkey is a leading nation in collecting complete data on its population through the use of a modern census. Based on available information, the development of Turkey's population can be summarized as follows: 1) in the last 20 years, Turkey's population increase rate has been 2% annually, very high by world standards; 2) the average age is young, and the population's burden coefficient is above 80%; and 3) the geographical distribution of the population is uneven. The population density in central, eastern, and southeastern parts of the country is low, while the coastal provinces near the Black Sea, Mediterranean Sea, and Aegean Sea have a high population density. In the last 50 years, the political situation in Turkey has remained stable. The national economy has developed rapidly, and the infant mortality rate has declined as a result of advancements in medicine and health care. Since Turkey is an Islamic country, birth control and abortion are not popular. The traditional early marriage for women and high illiteracy rate among women have contributed to a rapid population growth. In the past 20 years, however, the national economy has been overburdened by a rapid population growth. Problems of unemployment, a housing shortage in cities, inadequate public health facilities, a shortage of schools, a decline in farm land and inadequate food supplies have become increasingly obvious. Economically speaking, Turkey is much better than most developing nations. With its current foundation and rich natural resources, the country needs only to reduce the natural population increase rate slightly in order to achieve a balanced economic development.

  19. Oil and Gas Emergency Policy: Turkey 2013 update

    Oil has been one of the main energy sources in Turkey, accounting for some 28% of the country’s total primary energy supply (TPES) in 2011. Turkey’s oil demand slightly increased from 637 kb/d in 2003 to 670 kb/d in 2012, although it dropped down from 678 kb/d in 2009 to 650 kb/d in 2010. The transport sector accounted for half of total oil consumption in 2010. Domestic oil production is in decline in Turkey, amounting to 45 kb/d or about 6.7% of total consumption in 2012. In 2012, Turkey imported 712 kb/d, consisting of about 392 kb/d of crude oil and some 320 kb/d refined products. Around 39% of total crude oil imports came from Iran. Crude oil and petroleum products are mainly undertaken by tankers and two major international pipelines running through the country with a total annual handling capacity of 2.8 mb/d. In the country, there are four operational refineries with a total crude distillation capacity of around 610 kb/d. Turkey meets its 90-day stockholding obligation to the IEA by placing a minimum stockholding obligation on industry. Under the relevant acts, refineries and fuel distribution companies are obliged to hold at least 20 days of product stocks based on the average daily sales of previous year, while eligible consumers that use more than 20,000 tonnes annually are required to hold 15 days’ consumption of each type of liquid fuel. Turkey held some 61 million barrels of oil stocks at the end of January 2013, equating to 99 days of 2011 net-imports. Around 55% of total oil stocks are held in the form of crude oil. The use of emergency oil stocks is central to Turkey’s emergency response policy, which can be complemented by demand restraint measures. The share of natural gas in the country’s TPES significantly increased at 32% in 2011. Turkey’s gas demand significantly increased from 0.7 billion cubic meters (2 mcm/d) in 1987 to 45.3 bcm (124 mcm/d) in 2012, while indigenous natural gas production totalled some 0.63 bcm in the same year

    1994-04-01

    Postharmostomum gallinum (Trematoda: Digenea; Brachylaimidae) is reported for the second time from the wild turkey (Meleagris gallopavo) in North America. Seventy-six, 14 and three sexually mature specimens, respectively, were removed from the ceca of three of five wild turkeys collected in south-eastern New Mexico (USA). Local transmission of this infection was inferred since 10 immature specimens of P. gallinum also were collected from one host. In the turkey with the greatest intensity of mature trematodes, a concurrent hemorrhagic inflammation of the cecum apparently was associated with this infection. Specimens of P. gallinum from these wild turkeys were morphologically indistinguishable from, but their body and egg measurements were larger than, specimens described from the usual Eurasian galliform and columbiform hosts.

  1. COAL CONSUMPTION AND ECONOMIC GROWTH IN TURKEY

    2013-01-01

    Full Text Available This aim of this paper is to use asymmetric causality tests to examine the coal consumption and Gross Domestic Product (GDP relationship in Turkey based on data from 1980 to 2006. To investigate this relationship, a multivariate system is employed by including fixed capital formation and labor force variables into the model. The empirical results obtained from asymmetric causality tests show no causality for coal consumption and GDP relationship in Turkey. The results indicate that coal consumption does not affect growth; hence, energy conservation policies may be pursued without adversely affecting growth in Turkey. Thus, neutrality hypothesis is confirmed for Turkey. This means that a decrease in coal consumption does not affect economic growth and vice versa. In this case, policymakers should explore the feasibility of either decreasing the coal consumption or increasing the efficiency of coal consumption.

    Two E-W trending ophiolite belts crop out in SE Turkey, The southerly located ophiolites (Hatay, Koçali) were emplaced onto the Arabian Platform in Late Cretaceous whereas the northerly located ophiolites (Göksun, İspendere, Kömürhan, Guleman) were underthrust the S Tauride margin (i.e. Malatya-Keban Platform) in Late Cretaceous. Different tectonic models exist in the literature for the origin of these different ophiolite belts that we test here by a detailed palaomagnetic study: a) all the ophiolites in Turkey, including those in the study area were rooted from a single ocean basin to the N (i.e. the N Neotethyan Ocean Basin); b) all the ophiolites in SE Turkey were derived from the S Neotethyan Ocean Basin; c) the two ophiolite belts in SE Turkey are believed to have rooted from two different ocean basins; the Berit ocean to the north and the S Neotethys to the S. Our palaeomagnetic study from 72 different sites was focused on to the sheeted dyke complex, cumulate gabbros and extrusive sequences where available of each ophiolite from the N and S belts. We also sampled the unconformable cover units to distinguish emplacement related tectonic rotations from post-emplacement tectonic rotations. Here we report our first results obtained from the Göksun Ophiolite of the northern belt and the Hatay Ophiolite of the southern belt. Rock magnetic experiments showed evidence od magnetite/titanomagnetite as the main magnetic carriers at the majority of sites. Progressive thermal and alternating demagnetization revealed that the characteristic remanent component is removed between 500 and 580 ?C or 30-100 mT, respectively. Our new paleomagnetic results from the ophiolitic rocks emplaced in Arabian platform and the SE Anatolia show important implications to the spreading centre of the former ocean (s). Large counterclockwise rotations up to 100° are obtained from the sheeded dykes of the Hatay ophiolite in the Arabian plate with a paleolatitude of ˜16° , in contrast

    Full Text Available Abstract Background Recent evidence indicates that Gram-negative bacterial pathogens, the most common of which are Pseudomonas spp., Enterobacteriaceae, and Acinetobacter baumannii, are frequent causes of hospital-acquired infections. This study aims to evaluate the in vitro activity of doripenem and comparator carbapenem antibiotics against Gram-negative clinical isolates collected from COMParative Activity of Carbapenem Testing (COMPACT study centres in Turkey. Methods Ten centres in Turkey were invited to submit Pseudomonas aeruginosa, Enterobacteriaceae, and other Gram-negative isolates from intensive care unit (ICU/non-ICU patients with complicated intra-abdominal infections, bloodstream infections, or nosocomial pneumonia, including ventilator-associated pneumonia, between May and October 2008. Susceptibility was determined by each centre using E-test. A central laboratory performed species confirmation as well as limited susceptibility and quality-control testing. Results Five hundred and ninety six isolates were collected. MIC90 values for doripenem, meropenem, and imipenem, respectively, were 32, ≥ 64, and ≥ 64 mg/L against Pseudomonas spp.; 0.12, 0.12, and 0.5 mg/L against Enterobacteriaceae; and ≥ 64 mg/L for each against other Gram-negative isolates. In determining the susceptibility of hospital isolates of selected Gram-negative pathogens to doripenem, imipenem, and meropenem, we found that against all pathogens combined, the MIC90 for ICU compared with non-ICU isolates was higher. Conclusions Doripenem showed similar or slightly better activity than meropenem and better activity than imipenem against the Gram-negative pathogens collected in Turkey.

    The Ani ancient city, which is at 48 km distance to Kars (Turkey), is founded at the banks of the Arpacay River flowing in the vicinity of Turkey - Armenia border and is in the borders of Mevcut Ocakli Village. Recent studies show that the first settlement in Ani ancient city could be in the 5th millenium B.C.(Chalcolithic Period) and moreover, there were some buildings built in the Iron and Bronze Period. In the early 9th century, Ashot Msaker, who was Bagratuni dynasty (806-827), declared their first capital city at Bagaran, some 40 km south of Ani, and then transferred it to Kars in the year 929. In 961, King Ashot III (953-977) transferred the capital city from Kars to Ani. Ani expanded during the reign of King Smbat II (977-989). Recent research shows that by the early 11th century the population of Ani was over 100,000. After capture of Ashot, Ani surrendered to Byzantine controlled in 1045. A Greek governor was installed in the city. In 1064 a Seljuk Turkish army, headed by Sultan Alparslan, attacked and captured Ani. Then the Georgians captured Ani in 1124, 1161 and 1174. By the 14th century Ani was ruled by the Turkish dynasties, namely Jalayrids and the Kara Koyunlu. After the Persian Safavids ruled Ani, it became part of the Turkish Ottoman Empire in 1579. A small town remained within its walls until 1650 A.C. and it was completely abandoned by the middle of the 18th century. Examples of Sasani, Arabic, Armenian, and Seljuk architecture can be found among the Ani ruins. Ani is home to the first Turkish mosque built in Anatolia, namely Ebul Menucehr. The mosque was erected by the members of the Seljuk Dynasty in 1072. The first archaeological excavations were conducted at Ani in 1892. Since then, several archaeological excavations have been done in Ani. In the 2009 excavation season, magnetic methods were applied in Ani ruins to find the exact locations of the ruins. Magnetic Gradient Measurements were taken in front of Ebul Menucehr Mosque. After

    Mass-occurrences in the palaeontological record can act as proxy for the environmental activities and biotic crisis through time. It has to be noted that the ultimate causes are often unknown and not well understood and are still under comprehensive discussion. The formation of the ammonite beds (e.g. Orthoceltites) is either autochthonous or allochthonous (transported). Expected 3D modelling results will be essential to reach geodynamic, palaeooceanographic and palaeobiological conclusions. 3D reconstructed faunas, representing environmental changes as displayed by the sea-level and climate can become more obvious and the 'motor' behind the demise better understood. While the Carnian, an ammonite mass-occurrence (Anatolia, Turkey) was deposited within an intrashelf area on the western end of the Cimmerian System, with intermediate connection to both, the Neo-Tethys and the Palaeo-Thetys Oceans. The mass-occurrence can be observed over several square kilometers around Aşağiyaylabel and Karapinar. This ammonite mass occurrence (Orthoceltites sp.) is now located at the boundary from the Kartoz and the Kasimlar Formation. The ceratitid ammonite Orthoceltites dominated the ammonite fauna (approx. 99.9%; n > 1 000 000) and is accompanied by rare individuals of Klipsteina and Sirenites. Statistical analysis of the orientation and relative position of the ammonite shells hint to current or transport directions. 3D modelling of ammonites will lead to a geometrical reconstruction and shed light on the biostratinomic and additional diagentic processes. The proposed research integrates well established 3D visualisation and geometrical modelling techniques in an exciting palaeontological task of reconstructing the distribution and alignment of ammonite in a Triassic mass-occurrence from Turkey. Computed tomography and laser surface-scans of ammonites and computed tomography provide additional information on shape and internal structures, which will in a further step be

    Full Text Available Turkey has a strategic place in world politics. As Ahmad (1991: 226 and 1993 said, Turkey's strategic location on the Straits and on the cross-roads between Europe and Asia will remain unchanged. Turkey is a meeting point between Europe and Asia not only geographically, but also ideologically between Eastern and Western civilisation The Turkish secular and democratic system has provided a model to both the Islamic Middle East and the new Turkish states of the former Soviet Union.     The new state was created from the ruins of the Ottoman Empire in 1920s. Turkey has turned her face completely to the west since the foundation of the Republic. The economic and social development, as Hale examined (Hale, 1981, have proceeded in a predominantly liberal competitive political system since the 1940s.    This paper will concern itself with the Turkish political leaders. Firstly, a brief information about the political structure of contemporary Turkey will be given. Then, the major findings on Turkish top political elites will be presented. The top political elites comprise all the presidents, presidents of the TGNA, prime ministers, and ministers who served in three or more cabinets during the whole modern Republican history of Turkey. In doing this, the variables of age, educational level, education type, occupation, foreign languages, gender and marital status, family size were used.

    Solar energy is considered a key source for the future, not only for Turkey, also for all of the world. Therefore the development and usage of solar energy technologies are increasingly becoming vital for sustainable economic development. The main objective of this study is investigating the employment effects of solar energy industry in Turkey. Some independent reports and studies, which analyze the economic and employment impacts of solar energy industry in the world have been reviewed. A wide range of methods have been used in those studies in order to calculate and to predict the employment effects. Using the capacity targets of the photovoltaic (PV) and concentrated solar power (CSP) plants in the solar Roadmap of Turkey, the prediction of the direct and indirect employment impacts to Turkey's economy is possible. As a result, solar energy in Turkey would be the primary source of energy demand and would have a big employment effects on the economics. That can only be achieved with the support of governmental feed-in tariff policies of solar energy and by increasing research-development funds. - Highlights: > The objective of the study, is investigating employment effects of solar energy. > Using the capacity targets of the PV and CSP plants in solar roadmap of Turkey. > Direct employment has been calculated by constructing of the solar power plant. > If multiplier effect is accepted as 2, total employment will be doubled. > Validity of the figures depends on the government's policies.

    Full Text Available We call Oghuz Turkish spoken from Central Asia to Baghdad, the capital of the Abbasid Empire, since 11th century, as the Western Turkic. This period is divided into two branches in time. One of them is the Eastern Oghuz branch covering Eastern Anatolia and Azerbaijani and the other one is the Western Oghuz branch covering Ottoman field. The Eastern Oghuz branch covering Eastern Anatolia and Azerbaijani, and the Western Oghuz branch covering Ottoman field are represented by a single written language named as “Western Turkish” till 16thCentury. Azerbaijan and the Ottoman writing languages separated fromeach other in the 16th century as a result of the fact that the Azerbaijanterritory was dominated by Karakoyunlu and Akkoyunlu in the 15thCentury and Safavid Empire in the 16th century. For that reason,Western Turkic reaches the present day from the 16th century with twowriting languages including some phonetic and morphologic differences.Although the East Anatolian dialects have been in the Western Oghuzbranch, they still have the traits of the Eastern Oghuz branch in termsof phonetics and morphology.In studies of language products in the provinces of EasternAnatolia it is seen that the dialects of the region are in the domain ofAzerbaijan Turkish. So in this article, the studies of the dialects of theEastern Anatolia Region (Erzurum, Elazığ, Erzincan, Kars, Iğdır,Ardahan, Muş, Bitlis ve Van are examined; and the phonetic andmorphological similarities of this studies with Azerbaijani Turkic areidentified. 11. yüzyıldan itibaren Orta Asya’dan Abbasi Devleti'nin başkenti Bağdat’a kadar olan bölgede konuşulan Oğuz Türkçesine Batı Türkçesi denilmektedir.

    The 1999 Izumit Earthquake as the destructive earthquake occurred near the Marmara Sea. The Marmara Sea should be focused on because of a seismic gap in the North Anatolian fault. Istanbul is located around the Marmara Sea, so, if next earthquake will occur near Istanbul, fatal damages will be generated. The Japan and Turkey can share our own experiences during past damaging earthquakes and we can prepare for future large earthquakes in cooperation with each other. In earthquakes in Tokyo area and Istanbul area as the destructive earthquakes near high population cities, there are common disaster researches and measures. For disaster mitigation, we are progressing multidisciplinary researches. Our goals of this SATREPS project are as follows, To develop disaster mitigation policy and strategies based on multidisciplinary research activities. To provide decision makers with newly found knowledge for its implementation to the current regulations. To organize disaster education programs in order to increase disaster awareness in Turkey. To contribute the evaluation of active fault studies in Japan. This project is composed of four research groups. The first group is Marmara Earthquake Source region observationally research group. This group has 4 sub-themes such as Seismicity, Geodesy, Electromagnetics and Trench analyses. The second group focuses on scenario researches of earthquake occurrence along the North Anatolia fault and precise tsunami simulation in the Marmara region. Aims of the third group are improvements and constructions of seismic characterizations and damage predictions based on observation researches and precise simulations. The fourth group is promoting disaster educations using research result visuals. In this SATREPS project, we will integrate these research results for disaster mitigation in Marmara region and .disaster education in Turkey. We will have a presentation of the updated results of this SATREPS project.

  16. GUADALUPIAN BRACHIOPODS FROM WESTERN TAURUS, TURKEY

    VINCENZO VERNA

    2011-03-01

    Full Text Available  Here we describe 41 brachiopod species belonging to the orders Productida, Orthotetida, Orthida, Rhynchonellida, Athyridida, Spiriferida, Spiriferinida, and Terebratulida coming from the Guadalupian lower-middle part of the Pamuçak Formation at Çürük Dað, Antalya (Western Taurus, Turkey. Associated conodonts are also reported and illustrated. The brachiopod taxa are either pedicle attached genera, with one genus also stabilized by penetration of its elongate umbo, or free living concavo-convex semi-infaunal genera; this indicates that the energy of the environment was never very high, as in settings just below the fair weather wave-base or in a back-reef, more protected inner platform. The brachiopods from the Pamuçak Formation are very similar to the Wordian fauna of southeastern Oman, and they are similar to the Guadalupian assemblages of Chios, North Iran, South Thailand, and Salt Range. In comparison they share only a few taxa with the Guadalupian faunas of Central Afghanistan and Karakorum. Therefore the biotic affinity of the Guadalupian brachiopods of the Pamuçak Formation is clearly peri-Gondwanan. The brachiopod record at Çürük Dað has implications for understanding the pattern of the end-Guadalupian (pre-Lopingian biotic crisis. The pre-Lopingian crisis assemblages are quite diverse and nearly totally consist of Guadalupian genera and species except for a single Lopingian incomer. Their stratigraphic range terminates rather abruptly and the following 120 metres of shallow water limestones are barren of brachiopods, after which there is the first occurrence of Lopingian brachiopod taxa, which show a much lower biodiversity.  This pattern is different from that observed in South China and it shows that the end-Guadalupian crisis is not only characterized by taxonomic selectivity, but also by a strong local control on the extinction/recovery pattern of some groups.

    The eastern Mediterranean region is one of the most promising geothermal areas, with more than 250 geothermal fields discovered in Turkey (Parlaktuna, 2013), in a region of active tectonics and volcanism. Although the potential of these deep geothermal resources has not been systematically investigated yet, the geothermal activity of the western Turkey area is the most recent signature of the high heat flow (120-140 mW/m²; Aydin, 2005, from Teczan, 1995). Based on Turkish data, 2084 MWt are being utilized for direct applications and most of the energy originates from the Menderes Massif (Baba et al., 2015). This large-scale thermal anomaly at the surface is correlated to a long wavelength east-west increase of surface heat flow that could reflect the thermal state of Aegean subduction zone at depth. In order to better understand and characterize the possible connections between large-scale mantle dynamics and surface processes in space and time, we study the structure and thermal evolution of the Menderes Massif. Both the acceleration of the Aegean extension in the Middle Miocene and the recent escape of Anatolia have been proposed to result from several slab tearing events, the first one being located below western Turkey and the Eastern Aegean Sea. These events have triggered the formation of metamorphic complexes with contrasted exhumation P-T paths. While the extension in the Aegean domain is well-characterized with high-temperature domes in the center and east, the succession of several metamorphic events in the Menderes Massif and their significance in terms of geodynamics is still debated. Hence, the exhumation history is key to understanding the temporal and spatial distribution of the thermal signature of the Hellenic slab and its tearing/detachment. The Menderes Massif displays a large variety of metamorphic facies, from the Barrovian type metamorphism in the Eocene (the Main Menderes Metamorphism) to the coeval (?) HP-LT metamorphism on the southernmost

  18. Bronze Age metal artefacts found on Cyprus - metal from Anatolia and the Western Mediterranean

    2010-12-01

    Full Text Available Hundreds of Bronze Age metal artefacts excavated on archaeological sites in Cyprus have been analysed for their lead isotope and elemental composition in the Isotrace Laboratory, University of Oxford, in the years 1982-2002. In parallel, but in particular after 1995, hundreds of samples of minerals and slags collected from the mines and smelting sites around the Troodos Mountains were also analysed. Most of the results were published in various articles over the years, but the interpretation of some of the lead isotope data needs a current revision in view of new research conducted in Spain, Sardinia and southern France. It has been known that the lead isotope data for metal artefacts from the Cypriot Bronze Age sites shows that not all of the copper is consistent with origin from the Cypriot ores. In addition, the lead and silver artefacts found there must have been imported, because there are no lead or silver ores on Cyprus. The re-evaluation of the data shows that about 11 % of the analysed metal artefacts are consistent with the origin from the deposits in the Aegean and Turkey, while about 14 % with sources in the Western Mediterranean. This paper discusses in detail the current interpretation of the research into the sources of imported metal found in the Bronze Age context on Cyprus.

    Full Text Available This study aims at analysing effects of intermediate goods, capital goods and consumer goods on both import and export, and at determining the subsector led to deficits of balance of payments. To achieve this, various statistical techniques have been applied. To carry out the present study, data reported by the Central Bank of Turkey were used in the time period of 2000–2013.These results revealed that the economic factors (intermediate, capital, consumer goods are significantly effective on the deficits of balance of payments. The analysis also showed that the corresponding imported goods are effective parameters onboth import and export. Contrary to common expectation, it is concluded that the deficits of balance of payments in the external trade of Turkey stem from the imports of the consumer goods. This study reveals that the policies should be created to encourage the decreasing of the items caused the deficits. It is important to note that our findings are usually in agreement with the literature. Possibility of countries’ involvement into economic crises can be determined before the crises take place and the countries will be therefore warned according to the results obtained. All graphical and statistical results here have been produced by the authors through EViews 7.1.

    2016-09-01

    We present a regional assessment of the spatiotemporal trends in several hydro-climate variables from 1979 to 2010 in Turkey, one of the countries of the eastern Mediterranean vulnerable to climate change, using the two reanalysis products of the ECMWF: ERA-Interim and ERA-Interim/Land. The trend analysis revealed that an average warming of 1.26 °C [0.8-1.8] occurred in Turkey from 1979 to 2010, with high confidence intervals (95-99 %, mostly). Geographically, the largest warming (up to 1.8 °C) occurred in the western coastal areas next to the Aegean Sea and in the southeastern regions. The air temperature trends were generally confirmed by the in situ data from about 100 weather stations around the country, though in situ data indicated slightly higher trends ranging from 1 to 2.5°. With respect to the regional trends in hydrological variables, ERA-Interim and ERA-Interim/Land revealed quite different pictures: the ERA-Interim dataset indicated that there have been significant decreasing trends of precipitation, snow water equivalent (SWE) and runoff in some parts of inner/southeastern Anatolia (a total decrease of up to 250 mm in the upstream of the Euphrates, Kizilirmak and Seyhan basins), while ERA-Interim/Land showed no or minor trends in the same areas. Based on the extensive comparisons with precipitation and SWE gauge data, we can suggest that the hydrological trends shown by the ERA-Interim/Land dataset, which is said to be a model improvement, are relatively closer to the observations. From the hydrological trends revealed by the ERA-Interim/Land dataset, we can conclude that, despite the strong warming trends over Turkey from 1979 to 2010, there have been no widespread and strong hydrological trends for the same period throughout the country. In this regard, we can suggest that the impacts of global warming on the water cycle are not straightforward, especially at the regional scale, and future climate simulations indicating considerable

    2010-12-01

    Full Text Available This study shows how the theoretical debate between liberal egalitarianism and multiculturalism corresponds to the problem of minorities in Turkey. The differentiated group rights supported by the latter are contrasted with liberal egalitarianism policies to identify which is better suited to the goal of increasing equality in Turkey. The multiculturalist perspective is represented by the European Union (EU which favours differentiated cultural group rights, while the liberal egalitarian perspective is represented by Turkey’s constitutional citizenship policy. The central argument of this study is that awarding self-government rights to national minorities would not be sufficient to create equality in Turkey’s culturally diverse society. The article points to potential injustices that might result from providing different treating to distinct groups in Turkey, and discusses these with reference to inter-group and intra-group inequalities. Within this framework, the article then provides empirical evidence for the egalitarian critique of multiculturalism and seeks to demonstrate that EU minority conditionality, and in particular the self-government rights that it proposes, are unlikely to create a more democratic society in Turkey.

The Doğanca lamproite (K2O = 5.1-5.5 wt.%; K/Na = 2.78-2.89; MgO = 11.4-11.8 wt.%) consists of olivine (Fo71-86), diopside (Al2O3 = 1.0-5.0, Na2O = 0.2-0.6), phlogopite (TiO2 = 1.1-9.4, Al2O3 = 11.1-13.9), spinel (Mg# = 22.9-32.6; Cr# = 64-83.4), leucite, apatite, zircon, Fe-Ti-oxides and magnetite in a poikilitic sanidine matrix. The potassic volcanic units (lamproites and trachytes) in the region have similarly high Sr and low Nd isotopic compositions (87Sr/86Sr(i) = 0.70835-0.70873 and 143Nd/144Nd(i) = 0.51227-0.51232). The major and trace element compositions and Sr-Nd-Pb isotopic ratios of the shoshonitic, ultrapotassic and lamproitic units closely resemble those of other Mediterranean ultrapotassic lamproites (i.e., orogenic lamproites) from Italia, Serbia, Macedonia and western Anatolia. The Beğendik basalts show intraplate geochemical signatures with an Na-alkaline composition, an absence of Nb negative anomalies on primitive mantle-normalized multi-element diagrams, as well as low Sr (~ 0.70416) and high Nd (0.51293) isotopic ratios; and include olivine (Fo72-84), diopside, spinel, Fe-Ti-oxides and magnetite. The Oligocene Keşan volcanics were emplaced in the earlier stages of extension in Thrace, and represent the typical volcanic products of post-collisional volcanism. The continental crust-like trace element abundances and isotopic compositions of the most primitive early Miocene ultrapotassic rocks (Mg# up to 74) indicate that their mantle sources were intensely contaminated by the continental material. By considering the geodynamic evolution of the region, including oceanic subduction, crustal

    Full Text Available While LGBT studies have been problematizing normative categories of sexuality primarily in Western cultures, the status of lesbian, gay, bisexual, and transgender (LGBT individuals in non-Western societies remains understudied. This study examines the political attitudes toward LGBT individuals in Turkish society and explores the experiences of transgender individuals. While Turkey holds a strong economic position among Western countries, the situation of sexual minorities lags behind international standards. This study explores two research questions. First, what is the Turkish government’s outlook for the LGBT community? Secondly, what kind of problems and challenges do trans-individuals experience in Turkey? This study first introduces a macro-level analysis of the politics of gender identity in Turkey by analyzing the debates of four deputies in the Turkish Parliament, each representing their parties’ disparate viewpoints. Secondly, a micro-level analysis of previously collected interviews with twenty-five trans-individuals are also examined that shed light on the difficulties of being a trans-individual in Turkey. The content analysis shows that trans-individuals experience physical, sexual, and emotional violence, in addition to experiencing discrimination in employment, housing, and healthcare. The findings of this micro-level analysis elucidate the continuous discrimination, inequality, and violence that these individuals experience, while the macro-level analysis portrays the state’s discriminatory policies toward LGBT individuals in Turkey.

    2009-06-15

    Turkey's growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on? This report closely examine Turkey's plans to create a power infrastructure capable of providing the reliable electricity supplies necessary for sustained economic growth. It was compiled with on-the-ground research and extensive interview with key industrial and political figures. Today, hard coal and lignite account for 21% of Turkey's electricity generation and gas-fired plants account for 50%. The Alfin Elbistan-B lignite-fired plant has attracted criticism for its lack of desulfurization units and ash dam facilities that have tarnished the industry's image. A 1,100 MW hard-coal fired plant using supercritical technology is under construction. 9 figs., 1 tab.

    Full Text Available Turkey arthritis reovirus (TARV causes lameness and tenosynovitis in commercial turkeys and is often associated with gastrocnemius tendon rupture by the marketing age. This study was undertaken to characterize the biomechanical properties of tendons from reovirus-infected turkeys. One-week-old turkey poults were orally inoculated with O’Neil strain of TARV and observed for up to 16 weeks of age. Lameness was first observed at 8 weeks of age, which continued at 12 and 16 weeks. At 4, 8, 12, and 16 weeks of age, samples were collected from legs. Left intertarsal joint with adjacent gastrocnemius tendon was collected and processed for histological examination. The right gastrocnemius tendon’s tensile strength and elasticity modulus were analyzed by stressing each tendon to the point of rupture. At 16 weeks of age, gastrocnemius tendons of TARV-infected turkeys showed significantly reduced (P<0.05 tensile strength and modulus of elasticity as compared to those of noninfected control turkeys. Gastrocnemius tendons revealed lymphocytic tendinitis/tenosynovitis beginning at 4 weeks of age, continuing through 8 and 12 weeks, and progressing to fibrosis from 12 to 16 weeks of age. We propose that tendon fibrosis is one of the key features contributing to reduction in tensile strength and elasticity of gastrocnemius tendons in TARV-infected turkeys.

    An avian pneumovirus (APV) was isolated from commercial turkeys in Colorado (APV/Colorado) showing clinical signs of a respiratory disease. The results of virus neutralization and indirect fluorescent antibody tests showed that the APV/Colorado was partially related to APV subgroup A but was unrelated to APV subgroup B. Turkeys experimentally inoculated with the APV/Colorado were observed for signs, lesions, seroconversion, and virus shedding. Thirty-six 7-wk-old turkeys were distributed into three groups. Eighteen turkeys were inoculated oculonasally with APV/Colorado, six were placed in contact at 1 day postinoculation (DPI), and 12 served as noninoculated controls. Tracheal swabs and blood samples were collected at 3, 5, 7, 10, 14, and 21 DPI. Tissues were collected from three inoculated and two control turkeys on aforementioned days for pathologic examination and APV isolation. Inoculated turkeys developed respiratory disease, yielded APV at 3, 5, and 7 DPI, and seroconverted at 10 DPI. Contact turkeys yielded APV at 7 and 10 DPI. No gross lesions were observed in the turbinates, infraorbital sinuses, and trachea. However, microscopic examination revealed acute rhinitis, sinusitis, and tracheitis manifested by congestion, edema, lymphocytic and heterophilic infiltration, and loss of ciliated epithelia. The inflammatory lesions were seen at 3 DPI and became extensive at 5 and 7 DPI. Active regenerative changes in the epithelia were seen at 10 and 14 DPI. Serologic survey for the presence of antibodies in commercial turkeys (24,504 sera from 18 states) and chickens (3,517 sera from 12 states) to APV/Colorado showed seropositive turkeys in Minnesota, North Dakota, and South Dakota and no seropositive chickens. This report is the first on the isolation of an APV and APV infection in the United States.

    Full Text Available The purpose of this paper is twofold. First, drawing on data from the Household Labor Force Surveys over the period 2004-2013, it examines the determinants of the NEET (Not in Employment, Education or Training status for the Turkish youth. This is particularly important for Turkey as it has the highest NEET rate among the OECD countries. Second, it describes the movement of the youth across four states: education, employment, unemployment and inactivity. Probit results indicate that gender and educational attainment are key factors for explaining the NEET status. Findings also show that a greater number of household members that are in employment is associated with a lower likelihood of NEET. Transition analyses reveal that the state of inactivity remains highly persistent despite the substantial fall over the sample period. In addition, the rise in the persistence of education between 2007 and 2009 underlines the choice of the youth to stay in education in response to the fall in labor market prospects.

    In this study, changes from past to present in the departments of physics, chemistry, biology and mathematics, which are considered as the basic sciences in Turkey, are shown. The importance of basic science for the country emphasized and the status of our country was discussed with a critical perspective. The number of academic staff, the number of students, opened quotas according to years for these four departments at universities were calculated and analysis of the resulting changes were made. In examined graphics changes to these four departments were similar. Especially a significant change was observed in the physics department. Lack of jobs employing young people who have graduated from basic science is also an issue that must be discussed. There are also qualitative results of this study that we have discussed as quantitative. Psychological problems caused by unemployment have become a disease among young people. This study was focused on more quantitative results. We have tried to explain the causes of obtained results and propose solutions.

    Avian pneumovirus (APV) causes respiratory tract infection in turkeys and was first seen in the United States in Colorado in late 1996. In early 1997, the disease was recognized in Minnesota and caused estimated losses of up to 15 million dollars per year. This virus has not been reported in the other turkey producing states. We here report the seroprevalence of APV in Minnesota from August 1998 to July 2002. The average rate of seroprevalence has been 36.3% (range = 14.2%-64.8%). A seasonal bias was observed, with peak incidences in the fall and spring. A higher rate of seropositivity was observed in counties with the highest concentration of turkeys.

Antenatal examinations are important in selection for trial of labor, while birth management can be difficult when the patients present at emergency condition. But there is an increased chance of vaginal birth with advanced cervical dilation. This study attempts to evaluate factors associated with success of vaginal birth after cesarean section and to compare the maternal and perinatal outcomes between vaginal birth after cesarean section and intrapartum cesarean section in patients who were admitted to hospital during the active or second stage of labor. A retrospective evaluation was made from the results of 127 patients. Cesarean section was performed in 57 patients; 70 attempted trial of labor. The factors associated with success of vaginal birth after cesarean section were investigated. Maternal and neonatal outcomes were compared between the groups. Vaginal birth after cesarean section was successful in 55% of cases. Advanced cervical opening, effacement, gravidity, parity, and prior vaginal delivery were factors associated with successful vaginal birth. The vaginal birth group had more complications (P<0.01, but these were minor. The rate of blood transfusion and prevalence of changes in hemoglobin level were similar in both groups (P>0.05. In this study, cervical opening, effacement, gravidity, parity, and prior vaginal delivery were important factors for successful vaginal birth after cesarean section. The patients’ requests influenced outcome. Trial of

    Full Text Available Relationship between Turkey (Ottoman Empire and Austria started nearly 500 years ago. Towards the end of the Ottoman Empire the educational relationship began to concentrate. After 1850, Austrian scientists and teachers have made valuable services at educational institutions for Ottoman Empire. When archival documents had evaluated, it was understood that some of Ottoman citizens had completed their education at Austrian schools. As far as we know, Austrian teachers and clergy in Ottoman lands established fifteen schools especially in the 20th beginning of the century. The most well-established educational institutions of the Austrian School has been preparing to celebrate 130th anniversary in 2012. Other schools closed over time is understood. Austria and Turkey signed "Friendship Treaty" on 10 December 1923 in Ankara. This treaty is important in terms of the first treaty of the Republic of Turkey after Lausanne. Dozens of Austrian scientists and teachers from the first year of the Republic, came to Turkey, and have made services in various educational institutions. This development is too important for Republic of Turkey. Paul Wittek a scientist studied on Turkish language, history and culture, and other scientists specializing in the fields of architecture, such as Clemens Holzmeister makes this development more important for us. Since 1964, labor migration began to Austria from Turkey. The number of Turks in Austria, close to 220.000 due to migration of workers today. Recently, about 30.000 Turkish children living abroad has received their education with so many difficulties. Turkish children studying in Austria has been waiting an agreement between two countries for solutions.

    Full Text Available Abstract: IMF has been created to make international cooperation on financial matters stronger and for solving the problems of balance of payment. However, the IMF formed policies in order to solve problems of balance of payment till the 1980s, expanded its effectiveness much more by controlling the structural adjustment programs after the 1980s, and undertook the role as an international lender of last resort on crises caused by globalization trends. In developing nations, foreign and domestic deficit occurred due to infrastructural causes that have created economic instabilities portrayed through inflation and unemployment. Especially foreign debt problems sourced by the foreign trade deficit transformed into an economic crisis for these countries. Many countries affected by such economic crisis applied to IMF and its Stabilization Program with the aim of providing economic stability in the hopes of recovering. The important thing here to point out is that the economic programs used by countries during their economic crisis are supported by the IMF in reality. In this situation Mexico and Argentina can be given as a good example. IMF has undertaken the same mission in Turkey with seven stabilization programs put in practice and nineteen Stand-By Arrangements between them. But IMF has failed many times in Turkey just like in many developing countries. This is because IMF did not take into consideration economic and social structure of countries in stabilization programs put in practice. Today, Turkey has reached to an important point from the way of its relationship with IMF; more clearly, Turkey is determined to achieve its future without IMF. Turkey-IMF relationship in the framework of stand-by agreements in the past half century of our economic and political history has come to an ending point. After a period of 51 years of intense relations, Turkey decided to determine its calculations of credit limit by the way of advantages and

    Full Text Available In this paper, we attempt to explain that expanding current account deficit of Turkey can be a highlighting signal of its dependency on foreign capital inflows. When private non-financial firms borrow in foreign currency, they face currency mismatch in their balance sheets. Statistical analyses of aggregated balance sheet data of non-financial sector revealed that the negative gap between firms’ dollarized assets and liabilities has been increasing considerably in Turkey. This creates financial exposure by private non-financial sector. Given a high level of liability dollarization by firms in Turkish economy, it is exposed dramatically to the changes in external and domestic conditions.

    There are several EEW networks and algorithms under operation in Turkey. The first EEW system was deployed in Istanbul in 2002 after the 1999 Mw7.4 Kocaeli and Mw7.1 Duzce earthquake events. The system consisted of 10 strong motion stations located as close as possible to the main Marmara Fault line. The system was upgraded by 5 OBS (Ocean Bottom Seismometer) in 2012 located in Marmara Sea. The system works in threshold based algorithm. The alert is given according to exceedance of certain threshold levels of amplitude of ground motion acceleration in certain time interval at least in 3 stations. Currently, there are two end-users of EEW system in Istanbul. The critical facilities of Istanbul Gas Distribution Company (IGDAS) and Marmaray Tube tunnel receives the EEW information in order to activate their automatic shut-off mechanisms. The IGDAS has their own strong motion network located at their district regulators. After receiving the EEW signal if the threshold values of ground motion parameters are exceeded the gas-flow is cut automatically at the district regulators. The IGDAS has 750 district regulators distributed in Istanbul. At the moment, the 110 of them are instrumented with strong motion accelerometers. As a 2nd stage of the on-going project, the IGDAS company proposes to install strong motion accelerometers to all remaining district regulators. The Marmaray railway tube tunnel is the world's deepest immersed tube tunnel with 60m undersea depth. The tunnel has 1.4km length with 13 segments. The tunnel is monitored with 2 strong motion accelerometers in each segment, 26 in total. Once the EEW signal is received, the monitoring system is activated and the recording ground motion parameters are calculated in real-time. Depending on the exceedance of threshold levels, further actions are taken such as reducing the train speed, stopping the train before entering the tunnel etc. In Istanbul, there are also on-site EEW system applied in several high

    Full Text Available Fire fighting which used to be performed by volunteers thanks to the efforts of citizens in the Ottoman Empire has been organized in various ways from the beginning of the 18th century onwards, when the first fire fighting organization was established. Fire fighting services offered by local and central governments across the world is de-centralized in Turkey, in other words conducted by local administrations. An effective fire fighting service directly affecting the safety of those who make use of this service aims to minimize the loss of lives. On the other hand, a small mistake made by fire fighters and victims jeopardizes their lives. The present study is primarily intended to investigate, in terms of “effectiveness problems”, the organization of fire fighting services over time and current methods by which fire fighting services are put into action. It also aims to study the ways related services are offered within the context of the relationship between local and central governments. “The urgent need to reform emergency response institutions” marks the basic suggestion of the study, in which several other suggestions are made to solve the problems concerning fire fighting services.

    Peste des petits ruminants is an endemic disease of small ruminants in Turkey and vaccination has been the method of control but sporadic outbreaks have been reported. This study was carried out to characterize the local peste des petits ruminants virus (PPRV) by sequencing fusion (F) protein and nucleoprotein (N) gene segments and phylogenetic analysis, so as to focus on genetic variation in the field viruses. Samples were collected from sheep and goats clinically suspected of having PPRV infection in Central and Mediterranean regions of Turkey during 2009-2013. Phylogenetic analysis based on the F gene sequences showed that the field isolates in the present study belong to lineage 4 with other Middle East isolates. While N gene sequences revealed a different pattern, the field isolates in the present study clustered with previous Turkish isolates, which probably represents the true picture of molecular epidemiology for PPRV.

    Demodex folliculorum and Demodex brevis are common ectoparasites in humans. Demodex parasite infestations have not been determined in the province of Ordu. We determined the prevalence of Demodex species among humans in Ordu Provience, Turkey. Seven hundred ninety-nine subjects (438 males and 361 females) aged ≥ 18 years living in the central districts of Ordu Province, Turkey, were selected using the World Health Organization cluster sampling method. A superficial skin biopsy of the face was obtained from each subject. Six hundred sixty-nine subjects (83.7%) had a Demodex parasite. Factors significantly associated with the presence of Demodex infestation were: female gender, employment in the private sector, people who only occasionally wash their face and district of residence. Since Demodex ectoparasites were common in Ordu Province, it is suggested that the diagnosis and treatment of this ectoparasite should be carried out in the hospitals of this region.

    Anatolia records the consumption of several oceanic basins, from the Northern Neotethys domain, by north-dipping subduction until the end of Mesozoic. The associated obduction event occurred during Campanian, from North to South and from Greece to Oman, leading to the emplacement of ophiolite thrust sheets and associated ophiolitic mélange. In particular, the Sivas Basin in Eastern Anatolia is located at the boundary between the Kırsehir block to the East, Pontide arc to the North and Tauride Platform to the South, sutured by ophiolitic belts. The Sivas Basin formed a Tertiary fold-and-thrust belt, which exhibits mainly north verging thrust in Paleogene deposits, and South verging thrust in oligo-miocene sequence. To understand the northern verging thrust above south verging obduction, it is necessary to zoom out of the basin, and include a set of processes that affect the eastern Anatolia. This study aims to characterize the structural and sedimentary evolution of the Sivas Basin, based on a fieldwork approach, coupled to the interpretation of subsurface data, thermochronology and biostratigraphy. The Sivas Basin was initiated in a forearc setting relatively to the subduction of the Inner-Tauride Ocean while the associated ophiolites are obducted onto the northern passive margin of the Tauride margin. Early Maastrichtian to Paleocene deposits are represented by carbonate platforms located on ophiolitic highs, passing to turbidites and olistostomes toward the North. The early Eocene sediments, mainly composed of ophiolitic clasts, are deposited on a regional unconformity marked along the southern margin of the basin by incisions in response to the emergence of north-verging thrust. The middle Eocene sediments, intensively folded by northward thrusting, are mostly represented by flysch type deposits (olistostromes, mass-flows and turbidites). The onset of the compression is related to the initiation of the Taurus shortening in a retroarc situation, in response to

    Full Text Available Konya, which is known a conservative city in Central Anatolia, has an incredibly lively folk song tradition, which will be studied from different perspectives. One of these perspectives is the musical practice of male musiciansbehind the closed doors of the outlying houses behind the garden walls. This is stating that they do not want to appear in public. This gesture appears in the expression of emotions in the folk songs that are not spoken directly, but encoded in symbols in the expression of humane emotions (especially intimate ones. But that means no concealment of them, but rather a publication of the secret feelings in a authentic way, hence the singers and listeners know those meanings from the very beginning. In my paper, the symbols of Konya folk love songs will be presented. Texts have been chosen from among the printed songs by Mazhar Sakman, one of the most important people of this region. It is attempted here to highlight how and where they occur in the song context and which aspects are to be understood. The aim of the lecture is to bring the music practice in Konya with the way of expression of love feelings, their coding to be tapped in the context, in relation.

    Full Text Available Migrations from Turkey to abroad for half a century have proceeded in the recent times by undergoing important changes. Moreover, it has been observed that there exist various types and ways of foreigner migration from abroad to Turkey which began from 1980 onwards and became clarified in the 2000s. This study is aimed to focus on who migrated from abroad to Turkey and where they migrated later on the basis of the 2000 General Census.As in the internal migration, the external migration tends towards the western part of the country, particularly big cities. Thusly, % 44 of the migration occurred in big cities; % 33.4 in the centre of towns and provinces; the rest % 22.5 in the countryside. The fact that % 51.9 of immigrants were born in Turkey gives rise to "comeback migration" thought with regard to the external migration. Moreover, that % 77.7 of them are Turkish nationals supports this judgment. On the other hand, the foreign nationals whose number has reached to 50.251 (% 21.5 are non-negligible. The big cities where the external nationals are grouped and the touristic centers on the Aegean and Mediterranean coasts are also the areas immigrants of foreign origin have settled down.

    The depletion of tylosin residues in edible turkey tissues was followed after 3 days of administration of tylosin tartrate at 500 mg l-1 in drinking water, to 30 turkeys. Immediately after the end of the treatment (day 0) and at day 1, 3, 5 and 10 of withdrawal, six turkeys (three males and three females) per time were sacrificed and samples of edible tissues were collected. Tissue homogenates were extracted, purified and analysed by HPLC according to a method previously published for the analysis of tylosin residues in pig tissues. In all tissues, tylosin residues were already below the detection limits of 50 micrograms kg-1 at time zero. However, in several samples of tissues (skin + fat, liver, kidney, muscle), from the six turkeys sacrificed at that time, one peak corresponding to an unknown tylosin equivalent was detected at measurable concentrations. The identification of this unknown compound was performed by LC-MS/MS analysis of the extracts from incurred samples. The mass fragmentation of the compound was consistent with the structure of tylosin D (the alcoholic derivative of tylosin A), the major metabolite of tylosin previously recovered and identified in tissues and/or excreta from treated chickens, cattle and pigs.

    During cold periods in the Quaternary, global ice volume increased and as a result valley glaciers advanced and the vice versa occurred during the warm periods. Quaternary glacier fluctuations had been also recorded in the Turkish mountains. Recently, the chronology of Late Quaternary advances in the northern and western Turkish mountains was reconstructed by surface exposure dating. However, these advances in the eastern Turkey are not dated yet. In this study, we investigated paleoglaciations in Kavuşşahap Mountains, which is located to the south of Lake Van in eastern Turkey. These mountains are one of the extensively glaciated areas in Turkey. Glacial activity is evidenced by more than 20 U-shaped valleys. For instance, one of the prominent and well-preserved glacial landscapes of Turkey is situated in the Narlıca valley system. Lateral and terminal moraines in the valley system indicate more than 10 glacial advances. To build their chronology, 39 erratic carbonaceous boulders were sampled for surface exposure dating with cosmogenic 36Cl. We also reconstructed the ice margin reconstruction of the Narlıca paleoglacier using the accumulation area ratio and area-altitude balance ratio approaches. We estimated an equilibrium line altitude (ELA) of ca. 2900 m above sea level based on the maximum ice extend, which implied ca. 800 m decrease in the ELA during the Late Quaternary in comparison to the lower bound of the modern ELA estimate. The first results of the surface exposure dating will be presented.

    Full Text Available This paper analyzes numerical data and sectoral distribution relating to child labor in Turkey. The information is taken the labor force research data collected by the Turkish Statistical Institute. Several attempts have been made to resolve the problems of child workers in Turkey. The first stage was the implementation of the International Program on the Elimination of Child Labor (ILO/IPEC. After introduction of the program, many organizations started various activities directed towards children workers in Turkey. Since these initiatives were coordinated and complementary activities there were remarkable developments in the fight against problems of the child workers. The Turkish Statistical Institute examined the child labor force proportion by means of three separate statistical components and the results revealed that number of the child workers has a tendency to decrease. Despite some statistical research carried out in Turkey, the precise number of children that are working cannot be determined. Some of the leading factors can be listed as paucity of research carried out in this area, inaccurate official statistical data regarding the number of children who are working illegally, employed as unpaid family workers, working in the streets, working on the temporary or seasonal basis, and other related factors.

    Here we present the first complete genomic sequence of Marek's disease virus serotype 3 (MDV3), also known as turkey herpesvirus (HVT). The 159,160-bp genome encodes an estimated 99 putative proteins and resembles alphaherpesviruses in genomic organization and gene content. HVT is very similar to MDV1 and MDV2 within the unique long (UL) and unique short (US) genomic regions, where homologous genes share a high degree of colinearity and their proteins share a high level of amino acid identity. Within the UL region, HVT contains 57 genes with homologues found in herpes simplex virus type 1 (HSV-1), six genes with homologues found only in MDV, and two genes (HVT068 and HVT070 genes) which are unique to HVT. The HVT US region is 2.2 kb shorter than that of MDV1 (Md5 strain) due to the absence of an MDV093 (SORF4) homologue and to differences at the UL/short repeat (RS) boundary. HVT lacks a homologue of MDV087, a protein encoded at the UL/RS boundary of MDV1 (Md5), and it contains two homologues of MDV096 (glycoprotein E) in the RS. HVT RS are 1,039 bp longer than those in MDV1, and with the exception of an ICP4 gene homologue, the gene content is different from that of MDV1. Six unique genes, including a homologue of the antiapoptotic gene Bcl-2, are found in the RS. This is the first reported Bcl-2 homologue in an alphaherpesvirus. HVT long repeats (RL) are 7,407 bp shorter than those in MDV1 and do not contain homologues of MDV1 genes with functions involving virulence, oncogenicity, and immune evasion. HVT lacks homologues of MDV1 oncoprotein MEQ, CxC chemokine, oncogenicity-associated phosphoprotein pp24, and conserved domains of phosphoprotein pp38. These significant genomic differences in and adjacent to RS and RL regions likely account for the differences in host range, virulence, and oncogenicity between nonpathogenic HVT and highly pathogenic MDV1.

    All climate projections indicate that drastic changes are to occur in the Mediterranean Basin and Southwestern Asia. Detailed studies also foresee strong patterns of change in seasonality for most climate fields all across the country, threatening Turkey's rich biodiversity and diverse ecosystems already in trouble due to massive land use changes and careless resource extraction projects. It is therefore obvious that climate impact studies can benefit from detailed and continuous monitoring of relationships between climate and natural systems. Recently started efforts to build a phenology network for Turkey will hopefully constitute a component of a more comprehensive ecological observation infrastructure. The Phenology Network of Turkey Project saw its debut as a joint initiative of an academic institution (Istanbul Technical University) and a research NGO (Nature Conservation Center). It has been decided from the very beginning to rely a much as possible on Internet technologies (provided by the National High Performance Computing Center of Turkey). The effort is also inspired by and collaborates with already established networks in general and USA National Phenology Network in particular. Many protocols, instructional materials and Nature's Notebook application has been barrowed from the USA NPN. The project has been designed from the start as a two-faceted effort: an infrastructure to accumulate/provide useful data to climate/ecosystem research communities and a 'citizen science' project to raise nature and climate change awareness among all components of the society in Turkey in general and secondary education teachers and students in particular. It has been opted to start by gathering plant phenological data. A set with 20 plant species has been designed to serve as a countrywide 'calibration set'. It is also anticipated to salvage and extend as much of possible historical animal (especially bird and butterfly) observations.

    Full Text Available Transit countries exhibit many similarities with respect to state-led anti-transit and more restrictive actions toward contemporary transit migration flows. This paper examines the changes after 1990s in state concerns, behaviors, and policies regarding transit migration by taking Turkey as a case study. Which factors led to Turkey's increased attention to immigration, specifically transit migration in spite of its long history of immigration, emigration and the transit migration. Why has Turkey employed restrictive policies and projects to regularize immigration since 1993? How can we explain the anti-transit immigration projects in Turkey? I argue that two driving forces can explain the restrictive policies of Turkey as a transit state. First, Turkey attempts to reconfigure its state authority in different forms to respond to the challenges of irregular migration through immigration control. Second, the Turkish state`s concern is based upon the externalization/adoption of European Union's immigration control policies.

    @@ On December 17, 2004, after hard negotiations, the European summit finally reached an agreement to launch the negotiations with Turkey on its accession to the EU in October 2005. This is a very important change in the EU's policy towards Turkey. Under the background of so-called "war on terror" and "conflict of civilizations," the EU's above-mentioned decision is especially arresting. Through analyzing the dominant factors in the EU's policy towards Turkey, this paper tries to make a judgment on the future development of Turkish- EU relationship, the prospect of Turkey's accession to the EU and the influences over the development of European integration.

    Bacterial artificial chromosomes (BACs) provide an important resource in genetic mapping. An initial set of BACs corresponding to microsatellite markers in the turkey (Meleagris gallopavo) was isolated from the CHORI-260 turkey BAC library. The selected markers were distributed on both macro- and microchromosomes and included a genetically unlinked marker. End sequences were obtained for a subset of the recovered BACs and compared to the chicken whole genome sequence. Close association of the turkey BAC-end sequences and original marker sequences was generally conserved in the chicken genome. Gene content of the turkey BACs is predicted from the comparative sequence alignments.

    Human papillomavirus (HPV) infections have a broad range of clinical spectrum from subclinical or asymptomatic infection to anogenital carcinoma. The detection of HPV-DNA and determination of the risk groups in cervical cancer (CC) screening is very important because CC is considered to be a preventable illness which is the third most common cancer type of women in the world. The aims of this study were to investigate the presence of HPV-DNA in women by two different molecular methods and to compare their results together with the results of cytology, in Eskişehir, Central Anatolia, Turkey. A total of 1081 women aged between 30-65 years, who applied to Eskişehir Early Diagnosis, Screening and Training of Cancer Center (KETEM) for screening were included in the study. Three separate cervical samples were collected simultaneously from the participants for cytologic examination and molecular studies. In the first step of the study, all cervical samples were investigated for the presence of HPV-DNA by Hybrid Capture 2 (HC2; Qiagen, Germany) method. In the second part of the study, consensus real-time polymerase chain reaction (RT-PCR) (Takara Bio Inc., Japan) was performed in 152 samples which included HC2 positive and randomly selected negative samples, and then the HPV genotypes were detected by using a commercial kit based on pyrosequencing method (Diatech Pharmacogenetics S.R.L, Italy). In the first part of the study, HC2 test was found positive in 3% (32/1081) of the women, while in 4.4% (47/1081) Pap smear was positive alone or with HC2 test. Five (0.5%) samples yielded positive results with both of the methods, and four of them were positive for high risk HPV types. Cytology results were negative in 19 out of 23 (23/1081, 2.1%) samples that were reported as high risk HPV by HC2 test. On the other hand, 42 (42/1081, 3.9%) samples that were positive by cytology yielded negative results by HC2 test. In the second part of the study, 32 (21.1%) of 152 selected

    The intra-pineal calcification is a well-known phenomenon in mammals, however it is almost completely unknown in birds. The aim of the present work was to analyze morphology and genesis of the pineal concretions in the turkey. The studies were performed on the pineals collected from one-year-old turkeys (Meleagris gallopavo). In addition to standard morphological methods, the alizarin red S and potassium pyroantimonate methods were employed for localization of calcium at the light and electron microscopy level. In light microscopy, calcified concretions with diameters from 300 microm to 2 mm and quantities from 3 to 6 per gland were observed in all the examined pineals. They were stained red with alizarin S and showed the presence of collagen in Mallory's staining. Two types of cells were noted inside the concretion: polygonal and elongated ones. Using electron microscopy, three parts were distinguished within the calcification area. The peripheral part contained densely packed collagen fibrils, some elongated cells and numerous pyroantimonate precipitates demonstrating the presence of calcium ions. In the intermediate part, the fibrils were covered by almost continuous sheets of pyroantimonate precipitates and fused side by side. The central part showed an appearance of calcified hard tissue and contained some polygonal (osteocyte-like) cells. The obtained data demonstrated that the formation of the pineal concretions in the turkey is associated with the mineralization of collagen. This process is completely different from the mechanisms responsible for the formation of the concretions in the mammalian pineal.

    This study presents shear wave splitting analysis results observed at ISP (Isparta)broadband station in the Isparta Angle,southwestern Turkey.We selected 21 good quality seismic events out of nearly 357 earthquakes and calculated splitting parameters (polarization direction of fast wave, and delay time between fast and slow waves, ) from mainly SKS and a few SKKS phases of the selected 21 seismic events. Then, we compared calculated splitting parameters at ISP station (56° ≤ ≤ 205° ; 0.37s ≤ t ≤ 4s) with those previously calculated at ANTO (Ankara) and ISK (˙Istanbul)stations (27° ≤ ≤ 59°; 0.6s ≤ t ≤ 2.4s and 26° ≤ ≤ 54° ;0.6s ≤ t ≤ 1.5s) which are located at 230 and 379 km away from ISP station in central and northwestern Turkey, respectively.The backazimuthal variations of the splitting parameters at ISP station indicate a different and complex mantle polarization anisotropy for the Isparta Angle in southwestern Turkey compared to those obtained for Ankara and Īstanbul stations.

  7. ‘CHILD BRIDE’ PROBLEM IN TURKEY

    Full Text Available ‘Child Brides’ are described as girls who are forced to get married before they are 18 year old. The issue of child brides is a concern for undeveloped and developing countries as well as Turkey. This work aims to explore the prevalence, problems and causes related to the problem of ‘child brides’ as well as offering solutions for this problem. The literature shows that ‘child bride’ is quite widespread practice in Turkey. Moreover, forced marriage at an early age is problematic in many ways. In addition, there are some factors which contribute the problem including legal gaps, education level of the family and the daughter, economical conditions, stereotypes, traditional practices and sexism level. Finally, it is suggested that the reasons for the problem of ‘child brides’ are multi-dimensional and therefore it requires a similar approach.

  8. Inflation Differentials across Regions in Turkey

    Duran Hasan Engin

    2016-04-01

    Full Text Available The aim of the present article is to analyze the convergence of regional inflation rates in Turkey from 2004 to 2015 by adopting sigma convergence and distribution dynamics approaches. The outcomes of our research can be summarized in two groups. First, inflation disparities tend to decline over time, especially during the post-crisis period after 2010. Hence, the aggregate price stabilization and disinflation process in Turkey is coupled with convergence in inflation rates across regions. Second, in addition to the findings in the literature, we find that regions change their relative inflation rate positions quite often. This indicates that regional inflation behavior is random and non-structural, as the relatively high and low inflationary places tend to change their quintiles frequently. The results imply several policy suggestions. First, achieving inflation convergence is a harder task than initially understood, as it seems to show random behavior. Second, trade integration can be an option to foster regional price convergence.

    Poult survival is key to understanding annual change in wild turkey (Meleagris gallopavo) populations. Survival of eastern wild turkey poults (M. g. silvestris) 0-4 weeks posthatch was studied in southcentral Iowa during 1994-97. Survival estimates of poults were calculated based on biweekly flush counts and daily locations acquired via radiotelemetry. Poult survival averaged 0.52 ?? 0.14% (?? ?? SE) for telemetry counts and 0.40 ?? 0.15 for flush counts. No within-year or across-year differences were detected between estimation techniques. More than 72% (n = 32) of documented poult mortality occurred ???14 days posthatch, and mammalian predation accounted for 92.9% of documented mortality. If mortality agents are not of concern, we suggest biologists conduct 4-week flush counts to obtain poult survival estimates for use in population models and development of harvest recommendations.

    Nuclear medicine applications in Turkey started in the early 1950s, grew as an independent medical discipline and finally were recognized by the Ministry of Health in 1973. Later on, the professional organization of nuclear medicine physicians and other related professionals including radiopharmacists and technologists under the Turkish Society of Nuclear Medicine were established in 1975. Recently after completing more than a half century in Turkey, nuclear medicine has proved to be a strong and evolving medical field with more than 600 physicians serving for the changing needs of clinical practice throughout these years. This article describes past and present facts in this field and attempts to provide insights into the future which hopefully will be brighter than before.

    1985-01-01

    A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the eastern wild turkey (Meleagris gallopavo sylvestris). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat). HSI models are designed to be used with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.

    2017-03-01

    Full Text Available Equivalence scales have a crucial role in poverty measurement. For Turkey, there are no available up-todate equivalence scales, representing Turkish data. There were no efforts for calculation of equivalence scales at the regional level. The aim of the paper is to calculate and propose an equivalence scale for Turkey and estimate regional differences. Besides the models with Engel method, different equivalence scales were estimated by Almost Ideal Demand System. The results of the first model of AIDS approach composed of 5 age groups, is proposed for Turkey, but for simplicity the results of the second AIDS model could be used as well. In this model, the equivalence scale for Turkey is calculated as 0.65 for each additional adult after the first one and 0.35 for each child. For regional equivalence scales, we use two methods and comare the results. In the first one, regressions were run for each region separately and in the second one, dummy variables introduced. The highest difference in the results of the two methods was observed in Istanbul region. The findings for the regional scales are less reliable as the household size is bigger. This limitation is due to the relatively small size of the data sets. Having surveys with higher sample sizes would enable better results. After getting the results some conclusions could be drawn especially with regard to child cost differences among regions. It was expected to have higher costs for children in poorer regions and the regional results have confirmed this hypothesis.

    The Turkish hydropower market provides huge opportunities for investors and suppliers. Successful market entry is not easy, however, as the market is still not fully liberalized, the need for local intelligence is large and the competition is increasing. There are also potential political, reputational and environmental risks, typical for an emerging economy. The World Bank global 'Ease of doing business' ranking (2010), ranks Turkey as number 73 of 183 countries. (Author)

    Full Text Available This paper aims to investigate validity of “Export-led Growth Hypothesis” for Turkey using quarterly data in period from 2003:Q1 to 2015:Q1. Hypothesis argues that there is causality relationship from real export to real Gross Domestic Product (GDP. Johansen cointegration test, Gregory-Hansen cointegration test, Toda-Yamamoto causality test, Fully Modified Ordinary Least Squares (FMOLS, Canonical cointegrating regression (CCR and Dynamic ordinary least squares (DOLS methods were used in this study. Findings can be summarized as follows: a According to Johansen cointegration test there is no relationship among variables in the long-run whereas Gregory-Hansen cointegration test has determined relationship in the long-run; b According to Toda-Yamamoto causality test there is bidirectional causality between real export and real GDP. This finding proves the validity of “Export-led Growth Hypothesis” for Turkey; c According to FMOLS, CCR, DOLS methods a 1% increase in the real export increases the real GDP by 1.5195%, 1.5552%, 1.3171% respectively in the long-run. These methods prove the validity of “Export-led Growth Hypothesis” for Turkey.

    Turkey has a short history of forensic medicine compared to the developed countries. Sultan Mahmud II established the first medical school of the Ottoman Empire named as Mekteb-i Tibbiye-i Sahane to provide health services to the army in 1839 [Gok S. Tomorrow, today and yesterday of the forensic medicine. 1st ed. Istanbul: Temel printing office; 1995]. It is also accepted as an important milestone of both medical education and forensic medicine in Turkey [Gok S and Ozen C. History and organization of forensic. 1st ed. Istanbul: Istanbul University Cerrahpasa Medical School Publications; 1982]. The first lecturer of forensic medicine at Mekteb-i Tibbiye-i Sahane was Dr. Charles Ambroise Bernard (C.A.). and he was also the first to perform autopsy in the history of Ottoman Empire [Gok, 1995]. Approximately 40 years after the first forensic medicine lecture in 1879, the Department of Medical Jurisprudence was established as a division of Zabita Tababet-i Adliye (Law Enforcement Office) in Istanbul [Sehsuvaroğlu and Ozen. History and development of forensic medicine in the world and in our country. Mag Istanbul Univ Med Fac 1974;36(60)]. This paper documents the first two cases of autopsies performed in Turkey with the original papers from the National Library.

    Full Text Available Among the global problems since we met the phenomenon of globalization, the water has also taken its place. Economic analysis of water have become a topic of examination by many economist in recent years. Water is one of the important needs of human life. Water has an important place in respect of its role in maintaining a healty way of life. However, our country’s water resources are getting polluted day by day and the amount of water need the per capita is inceasing fast year by year due to population growth. Water quality can not be observed in Turkey and the necessarydata bank is unable to be formed. Protection of water resources and the evaluation of if in accordance with beneficial use can be only done with an integrated management mechanism. The purpose of this study is to make economic analysis of water located in natural resources. In this context the analysis of water supply and demand, the place of water in the economy, water resources and use of them in Turkey, in the World and EU, finally SWOT analysis of Turkey in terms of water resources were performed.

    In this study, a new formula based on meteorological and geographical data was developed to determine the solar-energy potential in Turkey using artificial neural-networks (ANNs). Scaled conjugate gradient (SCG) and Levenberg-Marquardt (LM) learning algorithms and a logistic sigmoid transfer function were used in the network. Meteorological data for the last four years (2000-2003) from 18 cities (Bilecik, Kirsehir, Akhisar, Bingol, Batman, Bodrum, Uzunkopru, Sile, Bartin, Yalova, Horasan, Polatli, Malazgirt, Koycegiz, Manavgat, Dortyol, Karatas and Birecik) spread over Turkey were used as data in order to train the neural network. Meteorological and geographical data (latitude, longitude, altitude, month, mean sunshine duration, and mean temperature) were used in the input layer of the network. Solar radiation is the output layer. One-month test data for each city was used, and these months data were not used for training. The results show that the maximum mean absolute percentage error (MAPE) was found to be 3.448% and the R{sup 2} value 0.9987 for Polatli. The best approach was found for Kirsehir (MAPE=1.2257, R{sup 2}=0.9998). The MAPE and R{sup 2} for the testing data were 3.3477 and 0.998534, respectively. The ANN models show greater accuracy for evaluating solar-resource possibilities in regions where a network of monitoring stations has not been established in Turkey. This study confirms the ability of the ANN to predict solar-radiation values precisely (Author)

    Based on the earthquake event data accumulated by the Turkish National Seismic Network between 2007 and 2013, the local magnitude (Richter, Ml) scale is calibrated for Turkey and the close neighborhood. A total of 137 earthquakes (Mw > 3.5) are used for the Ml inversion for the whole country. Three Ml scales, whole country, East, and West Turkey, are developed, and the scales also include the station correction terms. Since the scales for the two parts of the country are very similar, it is concluded that a single Ml scale is suitable for the whole country. Available data indicate the new scale to suffer from saturation beyond magnitude 6.5. For this data set, the horizontal amplitudes are on average larger than vertical amplitudes by a factor of 1.8. The recommendation made is to measure Ml amplitudes on the vertical channels and then add the logarithm scale factor to have a measure of maximum amplitude on the horizontal. The new Ml is compared to Mw from EMSC, and there is almost a 1:1 relationship, indicating that the new scale gives reliable magnitudes for Turkey.

    Pleural mesothelioma, lung cancer, pleural calcification and fibrosis, and interstitial parenchymal fibrosis have been observed among inhabitants of several villages in south-central Turkey. Earlier reports have stated that environmental and lung tissue samples from this area contained the fibrous zeolite mineral erionite, and this mineral has generally been assumed to be the agent responsible for these endemic pathological conditions in the absence of asbestos outcroppings and usage. Several different kinds of asbestos minerals in addition to erionite have now been found in environmental samples taken from the villages where these diseases occur. The lung tissues of mesothelioma patients from these villages contain both fibrous zeolites and asbestos minerals.

    Full Text Available The total arable land of Turkey is about 28,054,000 ha. The main income of the country is agriculture and agriculture based industry. However, the prime soils cover only 17.5% of the total land surface and the productivity of the rest of the soils is limited by topographical, chemical (e.g. high calcium carbonate content, alkalinity and low organic matter, and physical (e.g. water logging, texture attributes. The diverse topography along with deforestation and unsuitable tillage and irrigation management has been inducing the rate of erosion in the country for centuries. The majority of the country’s soils (76.5% are prone to erosion risk due to the dominant steep slopes (>6%, and 72% of the soils are more or less affected from water and wind erosion. Alongside these unsuitable conditions, the misuse of lands, i.e. soil sealing, soil exploitation, over use of fertilizers and irrigation, improper use of indigenous environmental friendly, agro-ecosystems, constantly degrade the soils of the country. Soils with high production capacity and with a wide range of agricultural uses, cover 7% (about 5 million ha of the total land area (77.9 million ha of Turkey. This proportion is equal to about 1/5 of the potential agricultural soils of the country. The highly to moderately productive soils (soils of Land Capability Class I, II, III comprising an area of 19.1 million ha, with none (LCC I to one or more moderate to severe limitations (LCC II and III for some uses, require some kind of conservation practices to assure stability and sustainability of production as the essential part of the management system.

    The occurrence and seasonal patterns of transmission of the blood protozoa of wild turkeys (Meleagris gallopavo silvestris) were studied at Tallahala Wildlife Management Area (TWMA) (Jasper County, Mississippi, USA). Blood smears obtained from wild turkeys in winter, spring and summer, and from sentinel domestic turkeys throughout the year were examined for Haemoproteus meleagridis and Leucocytozoon smithi. Whole blood from wild turkeys captured in summer was subinoculated into malaria-free domestic turkey poults and recipient birds were examined for Plasmodium spp. The prevalence of H. meleagridis and L. smithi were not different (P greater than 0.05) between adults and juveniles or between male and female turkeys in any season. Leucocytozoon smithi was not detected in poults in summer or in juveniles examined in winter. Sentinel studies and information from wild birds revealed that transmission of H. meleagridis and L. smithi did not overlap. Haemoproteus meleagridis was transmitted from May through November, while L. smithi was transmitted only from January through April. The onset of transmission of H. meleagridis coincided with peak hatching (mid-May) and brood-rearing (May-November) of turkey poults. Plasmodium spp. were not found in turkeys from TWMA (n = 27) nor in birds from three widely separated counties (n = 28) in Mississippi.

    The province of Batman, located in southern Anatolia, has a population of approximately 500,000. To our knowledge, there exists no information regarding the environmental radioactivity in this province. Therefore, gamma activity measurements in soil, building materials and water samples and an indoor radon survey have been carried out in the Batman province. The mean activity concentrations of the natural radionuclides (226Ra, 232Th and 40K) and a fission product (137Cs) were 35+/-8, 25+/-10, 274+/-167 and 12+/-7 Bq kg(-1), respectively, in the soil samples. The concentrations of 226Ra, 232Th and 40K in the selected building materials ranged from 18 to 48 Bq kg(-1), 8 to 49 Bq kg(-1) and 68 to 477 Bq kg(-1), respectively. All the calculated radium equivalent (Raeq) activity values of the building material samples are lower than the limit of 370 Bq kg(-1), equivalent to a gamma-dose of 1.5 mSv year(-1). The activity concentrations of 226Ra, 232Th and 40K in tap waters collected from the study area were determined with mean specific activity concentrations of 42+/-15, 35+/-9 and 524+/-190 mBq L(-1), respectively. Indoor radon measurements were made at 95 dwellings in Batman using a CR-39 detector. The radon concentration levels were found to vary from 23 to 145 Bq m(-3). The arithmetic mean of the measured radon concentration levels was found to be 84 Bq m(-3) with a standard deviation value of 23 Bq m(-3). The measurement results obtained in this study did not significantly differ from those taken in other parts of the country. The data generated in this study can be used to determine whether the Batman province is in a normal or high background radiation area and provides a valuable database for future estimations of the impact of radioactive pollution.

    Toxoplasmosis was diagnosed in a free-ranging wild turkey (Meleagris gallopavo) from West Virginia (USA) in June 1993. Gross findings included emaciation, splenomegaly, multifocal necrotizing hepatitis and splenitis, and crusting dermatitis on the head and neck. Histologically, multifocal necrosis with mononuclear inflammation was present in kidney, liver, spleen, heart, lungs, and pancreas. Toxoplasma gondii was confirmed in sections of liver by avidin-biotin immunohistochemical analysis. Subsequently, a retrospective serosurvey of wild turkeys for T. gondii antibodies was conducted using turkey sera collected between 1984 and 1989. An antibody prevalence of 10% was detected in 130 birds from 21 locations in the southeastern United States. While wild turkeys in the Southeast have T. gondii antibodies, this is only the second natural case of fatal toxoplasmosis reported; it appears that wild turkeys infrequently develop clinical disease when infected with T. gondii.

    Full Text Available Native turkeys are kept as domestic bird in rural environments and can be infected with bacterial, viral and parasitic agents. Capillaria and Ascaridia are nematodes of small intestines of domestic birds such as turkey. Small intestine trematod of birds like echinostomiasis need intermediate hosts for evolution. Raillietina tetragona and Raillietina echinobothrida are parasites in small intestines of birds. These parasites can cause economic loss and create problems for turkey. The purpose of this study was to determine the genus and species, frequency and severity of gastrointestinal helminth parasites. Gastrointestinal of 60 slaughtered turkeys of Amol city were necropsied and examined. 25% of the samples were not contaminated and 75% of samples were infected with nematode, cestode and trematode. Prevalence and parasite species, including: 20% Capillaria, 51% A. gali, 8% R. tetragona, 8% R. echinobothrida and 11% Echinostoma. The results indicated that the highest prevalence of helminth parasites in turkeys of Amol and north of Iran was nematode.

  6. Immigration Control in Transit States: The Case of Turkey

    Full Text Available Transit countries exhibit many similarities with respect to state-led anti-transit and more restrictive actions toward contemporary transit migration flows. This paper examines the changes after 1990s in state concerns, behaviors, and policies regarding transit migration by taking Turkey as a case study. Which factors led to Turkey’s increased attention to immigration, specifically transit migration in spite of its long history of immigration, emigration and the transit migration. Why has Turkey employed restrictive policies and projects to regularize immigration since 1993? How can we explain the anti-transit immigration projects in Turkey? I argue that two driving forces can explain the restrictive policies of Turkey as a transit state. First, Turkey attempts to reconfigure its state authority in different forms to respond to the challenges of irregular migration through immigration control. Second, the Turkish state`s concern is based upon the externalization/adoption of European Union’s immigration control policies.

    The role of hepatitis B virus (HBV) genetics in the clinical manifestations of infection is being increasingly recognized. Genotype D is one of eight currently recognized major HBV genotypes. The virus is ubiquitous worldwide, but shows different features in different regions. One hundred and ninety-eight patients with chronic HBV infection were enrolled in this study, 38 of whom had been diagnosed with cirrhosis of the liver and/or hepatocellular carcinoma. HBV DNA was isolated from the patients' blood samples and the entire genome and/or the basal core promoter/core promoter region sequenced. Phylogenetic analysis of the complete genomes revealed that subgenotype D1 is the most prevalent subgenotype in Turkey, but there was no definite phylogenetic grouping according to geography for isolates from different regions within Turkey, or for isolates in Turkey relative to other parts of the world. Turkish isolates tended to be genetically similar to European and central Asian isolates. Overall, HBV-infection in Turkey appears to be characterized by early HBeAg seroconversion, a high incidence of the A1896 core promoter mutation and a small viral load. Genotype D characteristic mutations A1757 and T1764/G1766 were found in the BCP region. T1773 was associated with T1764/G1766 and a larger viral load. In conclusion, infection with HBV genotype D in Turkey has a similar clinical outcome to that of Europe and central Asia. Genotypic mutations in genotype D may be linked with disease prognosis in Turkey, but further studies with higher sample numbers and balanced clinical groups are needed to confirm this.

    Full Text Available The topic of article is bilateral economical and foreign trade relations between Turkey, which has started to apply outward-oriented economic policies since globalization and Moldova, which has done market transition after breaking up with the Soviet Union. Within this frame, the subject of article has been searched in depth as follows: general overview of Turkey’s economic relations, overall picture of Moldovan-Turkish relations, short exposition of Moldovan economy and bilateral economic and foreign trade relations of Moldova and Turkey. The topic of article is a current issue. Because Moldova, which is closed to Turkey in terms of geography, culture and history always has been an attractive country politico-economically for Turkey since its independence. Bilateral economic relations starting with shuttle trade have formalized and further developed and Turkey became as one of top ten biggest economic and trade partner of Moldova. On this basis, the aim of study is to elucidate foreign trade of Turkey with Moldova and to compare performances of Turkey by years and by other countries, which have remarkable domination in Moldovan market. Within this scope, bilateral trade volume of Moldova and Turkey has increased year by year considering the past decade, which makes Turkey as the 7th largest import and 8th export partner of Moldova. Turkey aims to be one of the first three biggest economic partner of Moldova after entry into force of Free Trade Agreement (FTA, which was signed by both countries in 2014 to increase foreign trade volume up to 1 billion US dollars.

    Samples collected in 2008 and 2009, from 49 turkey flocks of 6 to 43 days in age and presenting clinical signs of enteric disease and high mortality, were tested by polymerase chain reaction and reverse transcription-polymerase chain reaction for the presence of viruses currently associated with enteric disease (ED) syndromes: astrovirus, reovirus, rotavirus, coronavirus, adenovirus, and parvovirus. Turkey astroviruses were found in 83.67% of the cases and turkey astrovirus 2 (TAst-2) in 26.53%. The investigations directly demonstrated the high prevalence of turkey parvovirus (TuPV) in 23 flocks (46.9%) experiencing signs of ED, making this pathogen the second most identified after astroviruses. Phylogenetic analysis on a 527 base pair-long region from the NS1 gene revealed two main clusters, a chicken parvovirus (ChPV) and a TuPV group, but also the presence of a divergent branch of tentatively named "TuPV-like ChPV" strains. The 23 Hungarian TuPV strains were separately positioned in two groups from the American origin sequences in the TuPV cluster. An Avail-based restriction fragment length polymorphism assay has also been developed for the quick differentiation of TuPV, ChPV, and divergent TuPV-like ChPV strains. As most detected enteric viruses have been directly demonstrated in healthy turkey flocks as well, the epidemiology of this disease complex remains unclear, suggesting that a certain combination of pathogens, environmental factors, or both are necessary for the development of clinical signs.

    Full Text Available The aim of this study was to determine the rate of doping and performance enhancing drug use in athletes in Sivas, Turkey, and to analyze the main reasons for the use. This was a cross-sectional study based on a self-report questionnaire. The subjects filled the questionnaires under the supervision of the investigators during interviews. This questionnaire included 24 items describing the population in terms of demographics, sport practice, doping in sport and substance use. Moreover, we assessed the frequency of doping drug use. The number of respondents was 883, of which 433 athletes and 450 healthy non-athletes (control group. The mean age of the total volunteers was 21.8 ± 3.7 yrs. The male and female ratios were 78.2% and 21.8% respectively. Doping and performance enhancing drug usage rate was 8.0% (71cases in 883 subjects. Doping drug use among the athletes was significantly (p < 0.05 higher (14.5% compared with the non-athletes (1.8%. The agents used were anabolic steroids in 60.5%, l-carnitene in 12.7%, erythropoietin in 5.4%, Na-bicarbonate in 11.3% and creatinine in 14.1% of 71 cases. The reasons for doping use were to have a better body condition in 34 cases (47.9% and to solve weight (gaining or loosing problems in 8 (11.3% cases. Since the potential side effects of doping drugs are not satisfactorily familiar to the most users, the education of athletes on the matter must be a top priority

    Allergic diseases constitute a significant health problem in Turkey. According to a recent multicenter study, which used the ISAAC questionnaire, the mean prevalence of wheezing, rhinoconjunctivitis, and eczema in 10-yr-old school children during the past year was 15.8%, 23.5%, and 8.1%, respectively. A healthcare level system, regulated by Ministry of Health, is available in Turkey. Pediatric allergists and pediatric immunologists provide patient care at the tertiary level. Currently, 48 centers deliver care for allergic and immunologic diseases in children. There are 136 pediatric and 61 adult allergists/immunologists. Although the number of allergy/clinical immunology specialists is limited, these centers are capable of delivering many of the procedures required for the proper management and diagnosis of allergy/immunology. Pediatric allergy and/or immunology is a subspecialty lasting 3 yr and follows a 4-yr pediatric specialist training. Fellow training involves gaining knowledge in basic and clinical allergy and immunology as well as the performance and interpretation of laboratory procedures in the field of allergy and clinical immunology. The Turkish National Society of Allergy and Clinical Immunology (TNSACI) was officially established in 1989 and currently has 356 members. The society organizes a national congress annually and winter schools for fellowship training as well as training courses for patients and their relatives. TNSACI also has a strong representation in European Academy of Allergy and Clinical Immunology (EAACI) and European Society for Immunodeficiencies (ESID) through its participation in the executive committee, consensus reports, and initiatives in the diagnosis of allergic and immunologic diseases of children. The 30th Congress of the EAACI is also due to be held in Istanbul, Turkey, between June 11 and 15, 2011.

    Full Text Available It is known that the prejudices, which have emerged in the historical process, are engraved in the social memory of the nations; conveyed from the past to the future in language, art, literature, history and many other fields; and reproduced via media especially in the periods of crisis.Firstly, Turkish-German relations must be examined in the historical process in order to understand how Turkey and Turks are represented in the German media. Accordingly, Turkish-German relations are also important in terms of drawing a general framework on how the West, which has been preserving its topicality for centuries, sees Turkey.How the subjects and groups are represented in the media texts and what kind of an image are formed in relation with them reveals the social memory of the countries in which the media texts are produced.The prejudices which have emerged in the social memory of the German people in the historical process have an effect in forming the negative image of Turks by being reproduced via active media especially in the periods of crisis. A negative image of Turks is brought forward with the concepts such as human rights violations, fundamentalism, oppression against the women and the minorities, Kurdish-Turkish discrimination and Alawi-Sunni discrimination.German media uses as evidence and tries to emphasize their justness on the publications, photographs and images that take place in the Turkish media in terms of especially the concepts mentioned above.Media texts are dialogues which are formed between the target audience and the narrator who reflects the opinions of the authority elites that are the sources of news. For that reason, representation forms of Turkey and Turks will be associated with the historical prejudices and analyzed with the critical discourse analysis approach in the scope of this study.

    The Gulf of Gökova is located in southwestern Turkey near the Aegean Sea and surrounded by Datça Peninsula to the south, the island of Kos to the west and Bodrum Peninsula to the north. The Bodrum peninsula with a population of one million in summer season is one of the most populated touristic centers of Turkey. This region is also surrounded by numerous active seismic entities such as Ula-Ören Fault Zone, Gökova Graben etc.. and demonstrates high seismic hazard. In the past, many destructive earthquakes have occurred in southwestern Turkey. One of the destructive historical earthquakes is 1493 Kos event (Mw=6.9) caused heavy damage in Bodrum. In the instrumental period seismic activity in the Gökova region includes the Ms>6.0 earthquakes of 23 April 1933 (Ms=6.4), 23 May 1941 (Ms=6.0), 13 December 1941 (Ms=6.5) events. Intense earthquake activity (Mw5+) occurred in Gulf of Gökova in August 2004 and January 2005. Considering the high seismicity and population of this region, a strong ground motion monitoring system stationed in dense settlements in the Bodrum Peninsula: Bodrum, Turgutreis, Yalıkavak, Çiftlik and Ortakent was deployed on June 2015. The network consists of 5 strong motion recorders, has been set up with the aim of monitoring of regional earthquakes, collecting accurate and reliable data for engineering and scientific research purposes, in particular to provide input for future earthquake rapid reporting and early warning implementation projects on urban environments in the Bodrum peninsula and the surrounding areas. In this poster presentation, we briefly introduce the Bodrum Network and discuss our future plans for further developments.

    The goal of this study was to identify the strategies used by young homosexuals to manage their sexual minority status in Turkey. In-depth interviews were conducted with 15 self-identified homosexual university students. The data on the strategies employed by homosexuals suggested a categorization of these strategies into four interrelated areas: strategies employed in the process of self-acceptance; strategies to manage sexual stigma and prejudice; strategies specific to the coming-out process; and the strategies used while openly expressing their sexual identities.

    Full Text Available Creative activity is one of the most significant parts of architectural education. In the architectural curriculum organisation ‘design studio’ is the unique and preeminent subject. Freshman students encounter ‘design’ first in basic design course, before they know what designing incorporates. The Basic Design is the starting point of initiating creativity in architecture education. It helps each student to understand architecture as a creative and innovative practice in the first year of education. This study analyzes the characteristics of basic design course, the topics of the course contents and its significance in the architectural curriculum in Turkey as well.

    Hepatitis B virus (HBV) infection is a global major health problem. Currently, 10 genotypes (A-J) of hepatitis B virus (HBV) are identified based on the nucleic acid sequence heterogeneity, and these genotypes have been shown to have distinct geographic distribution. Reports of the previous studies indicated that the genotype D is the predominant type among hepatitis B patients in different regions of Turkey. However, recent studies indicated that other HBV genotypes are also seen with an increasing rate. Although epidemiological and clinical information on genotype E infection is currently limited, it is known that genotype E infection is common in West and Central Africa. In this report, the first case of HBV genotype E infection in Turkey was presented. A 22-year-old Nigerian male employee who resided in Manisa for five years was admitted to Celal Bayar University Hospital Manisa, Turkey, for his routine check-up. Since HBsAg was found positive, other HBV markers were tested with a repeated serum sample. Laboratory findings were as follows; HBsAg (+), anti-HBs (-), HBeAg (-), anti-HBe (+), anti-HBc (+), anti-HCV (-), anti-HIV (-), ALT: 44 U/L and AST: 45 U/L. HBV-DNA level was detected as 700 IU/ml by real-time PCR (Artus HBV QS RGQ Qiagen, Germany). HBV-DNA isolated from the serum sample of the patient was amplified by PCR and polymerase gene segment of HBV was directly sequenced. UPGMA method was used for phylogenetic analysis and Inno-LIPA HBV genotyping method (Innogenetics, Belgium) was performed to determine multiple HBV genotype infection. On the basis of those methods the genotype of the virus was identified as genotype E. The partial sequences of the HBV polymerase gene were loaded to the international DNA data bank (GenBank) for contribution to the global HBV surveillance. This report emphasized that besides genotype D the other HBV genotypes could be found in Turkey. Since the patient was an inactive HBsAg carrier before his residence in Turkey, this

    Full Text Available This study argues that Turkey's inclusion into the EU is important for the EU's security role. An essential reason behind the European Council decision to raise Turkey's status to that of candidate country is the EU's evolving security role. In other words, the estimates of the potential benefits of Turkey's inclusion into the EU's Common European Security and Defense Policy (CESDP and the costs entailed by its exclusion essentially shape the EU's policy towards Turkey.

    To study the chronological age of third-molar mineralisation of Turkish children from the southwest Eastern Anatolia region, the Demirjian staging method was used to determine the stage of the mineralisation of four third molars (18, 28, 38 and 48) and to compare third-molar development by sex and age with the results of previous studies. The study comprised 832 Turkish children from the southwest Eastern Anatolia region aged 6-16 years based on radiological evidence from digital orthopantomograms. The mean age of the 832 patients was 11.03±1.98 years, with 424 males (mean age, 10.97±1.97) and 408 females (mean age, 11.09±2.00). The orthopantomograms were scored by two observers. The Wilcoxon matched-pairs signed-rank test used to assess intra- and inter-observer assessment revealed strong agreement between both observers' measurements. Statistical analysis of the association between sex and age was performed with the Mann-Whitney U-test and the Wilcoxon test. Regression analysis was performed to obtain regression formulae for calculating the dental and the chronological age. The statistical analysis showed a strong correlation between age and third-molar development in males (R(2)=0.61) and females (R(2)=0.63). New equations (age=7.49+0.69, development stage (DS) 38+0.70, DS18) were derived for estimation of the chronological age. The results showed that there was no significant difference in mineralisation between 18 and 28 and 38 and 48 in males or females. For both sexes, the dental age was lower than the chronological age. Males reached the developmental stages earlier than females. In the whole population, the boys' and the girls' dental ages were 0.84 years and 0.16 years earlier, respectively, than their chronological ages. The use of third-molar teeth as a developmental marker is suitable, particularly when comparing the obtained standard deviation with other skeletal-age calculation techniques.

    Social Responsibility Projects (SRP) are important tools in contributing to the development of communities and applied educational science. Researchers dealing with engineering studies generally focus on technical specifications. However, when the subject depends on earthquake, engineers should be consider also social and educational components, besides the technical aspects. If scientific projects collaborated with municipalities of cities, it should be known that it will reach a wide range of people. Turkey is one of the most active region that experienced destructive earthquakes. The 1999 Marmara earthquake was responsible for the loose of more than 18.000 people. The destructive damage occurred on buildings that made on problematic soils. This however, is still the one of most important issues in Turkey which needs to be solved. Inspite of large earthquakes that occurred along the major segments of the North and East Anatolian Fault Zones due to the northwards excursion of Anatolia, the extensional regime in the Aegean region is also characterized by earthquakes that occurred with the movement of a number of strike slip and normal faults. The Dikili village within the Eastern Aegean extensional region experienced a large earthquake in 1939 (M: 6.8). The seismic activity is still characterised by high level and being detected. A lot of areas like the Kabakum village have been moved to its present location during this earthquake. The probability of an earthquake hazard in Dikili is considerably high level, today. Therefore, it is very important to predict the soil behaviour and engineering problems by using Geographic Information System (GIS) tools in this area. For this purpose we conducted a project with the collaboration of the Dikili Municipality in İzmir (Turkey) to determine the following issues: a) Possible disaster mitigation as a result of earthquake-soil-structure interaction, b) Geo-enginnering problems (i.e: soil liquefaction, soil settlement, soil

    Although avian species are known to be susceptible to infection with Mycobacterium spp. organisms, much remains unknown about the susceptibility of birds to infection with M. bovis. The objective of this current study was to determine if wild turkeys (Meleagris gallopavo) can be infected with M. bovis when inoculated by the oral or intratracheal route. Six turkeys were orally inoculated and another six were inoculated via the trachea with a high dose of M. bovis, 1 x 10(5) CFU/ml. Six turkeys were sham-inoculated controls. Two turkeys from each treatment group were sacrificed on days 30, 60, and 90 postinoculation. There were no gross or microscopic lesions consistent with mycobacteriosis in the 23 inoculated turkeys over the 90-day duration of this study. Fecal cultures were also consistently negative for M. bovis when sampled before inoculation and on days 1, 30, and 60 postinoculation. Two intratracheally inoculated turkeys were positive for M. bovis in visceral tissues at 30 days postinoculation. However, this finding was only indicative of passive persistence of mycobacteria in the tissues and not of infection, as there were no attendant lesions or clinical compromise to support infection. Thus, it can be concluded that young wild turkeys are resistant to infection with M. bovis and, therefore, pose minimal threat as reservoir or spillover hosts for this organism.

    Full Text Available The theorical literature on “Political Business Cycles” presents important insights on the extent to which politicians attempt to manipulate government monetary and fiscal policies to influence electoral outcomes, in particular, with the aim of re-election. In recent years “Political Budget Cycles” is the one of the most important topics in Political Business Cycles literature. According to Political Budget Cycles Theory, some components of the government budget are influenced by the electoral cycle and consequently an increase in government spending or decrease in taxes in an election year, leading to larger fiscal deficit. This incumbent’s fiscal manipulation is a tool that governments possess to increase their changes for re-election. In this paper we investigate the presence of Political Budget Cycles using a data set of budget balance, total expenditure and total revenue over the period 1994–2012. Our findings suggest that incumbents in Turkey use fiscal policy to increase their popularity and win elections, therefore fiscal manipulation was rewarded rather than punished by Turkish voters. The meaning of this result is that Political Budget Cycles Theory is valid for Turkey between 1994 and 2012.

    Electrophysiological and behavioral characteristics of the states of vigilance were analyzed in chronically implanted specimens of the turkey Meleagris gallopavo (M. gallopavo). Five different states of vigilance were observed throughout the nyctohemeral period: active wakefulness (AW), quiet wakefulness (QW), drowsiness (D), slow wave sleep (SWS) and rapid eye movement (REM) sleep. These states exhibit characteristics similar to those described in other bird species. Sleep periods displayed a polyphasic distribution; however, they showed the tendency to concentrate between 2100 and 0900 h in spite of the fact that the recordings were carried out under constant illumination. Sleep period occupied 45.71% of the nyctohemeral cycle, 43.33% corresponded to SWS, while 2.38% to REM sleep. The average duration of the REM sleep phase was very short, lasting 7.7+/-0.55 s (mean+/-S.D.). In contrast, its frequency was very high with an average recurrence of 268+/-63 phases throughout the nyctohemeral cycle. The short duration of REM sleep phase presented by the turkey as by other bird species studied up to now may be dependent upon genetic factors shared by this group of vertebrates.

    Full Text Available Regular physical exercise is recommended by the medical community, because it offers the potential to reduce the incidence of coronary events. On the other hand, vigorous exertion may act as a trigger of acute myocardial infarction and sudden cardiac death in susceptible individuals. Death during sports activities differs among sports disciplines and countries. In Turkey, soccer attracts more spectators than any other sports activity and the attention of the press and media, and is preferred over other sports by many young and middle-aged individuals. As autopsy-based studies are infrequent in literature and there is a lack of data detailing sudden death during physical activity in Turkey, we present a Turkish series of sudden deaths that occurred during soccer games based on data provided by the Morgue Specialization Department of the Council of Forensic Medicine. We identified 15 male cases of soccer-related sudden death aged from 10 to 48 years. Coronary artery disease was identified as the cause of sudden death in 11 cases

    We develop individual-based movement ecology models (MEM) to explore turkey vulture (Cathartes aura) migration decisions at both hourly and daily scales. Vulture movements in 10 migration events were recorded with satellite-reporting GPS sensors, and flight behavior was observed visually, aided by on-the-ground VHF radio-tracking. We used the North American Regional Reanalysis dataset to obtain values for wind speed, turbulent kinetic energy (TKE), and cloud height and used a digital elevation model for a measure of terrain ruggedness. A turkey vulture fitted with a heart-rate logger during 124 h of flight during 38 contiguous days showed only a small increase in mean heart rate as distance traveled per day increased, which suggests that, unlike flapping, soaring flight does not lead to greatly increased metabolic costs. Data from 10 migrations for 724 hourly segments and 152 daily segments showed that vultures depended heavily upon high levels of TKE in the atmospheric boundary layer to increase flight distances and maintain preferred bearings at both hourly and daily scales. We suggest how the MEM can be extended to other spatial and temporal scales of avian migration. Our success in relating model-derived atmospheric variables to migration indicates the potential of using regional reanalysis data, as here, and potentially other regional, higher-resolution, atmospheric models in predicting changing movement patterns of soaring birds under various scenarios of climate and land use change.

    The number of sinkholes (locally known as obruks) has increased rapidly in recent years near Karapınar, located in the semi-arid Konya Closed Basin in Central Anatolia. Nineteen sinkholes have formed in the last 33 years (1977-2009) as a result of the collapse of cavity roofs in the Neogene lacustrine limestone in the Obruk Plateau and beneath Quaternary lake sediments in the Karapınar-Hotamış Plain. Of these, 13 have formed within the past 4 years (2006-2009). The Obruk Plateau takes its name from the presence of several hundred paleo-sinkholes which formed as a result of natural processes during the Quaternary period. More recently, human activity has induced the formation of new sinkholes, which presents a hazard to life and property. Changing agricultural patterns have led to the opening of thousands of deep wells in recent years, and increased water pumping currently exceeds the sustainable yield of the aquifer. Thus the formation of sinkholes has been triggered by a combination of natural and human causes. The groundwater level has dropped almost 24 m in the vicinity of Karapınar during the last 26 years (1983-2008). Approximately 8 m of this drop occurred within the 4 years prior to the study (2005-2008). Legally-binding precautions must be taken to prevent further water table decline, in order to decrease sinkhole formation within the basin in the years to come.

    Sequence similarity was used to predict the position of expressed sequence tags (ESTs) in the genome of the turkey (Meleagris gallopavo). Turkey EST sequences were compared with the draft assembly of the chicken whole-genome sequence and the chicken EST database by BLASTN. Among the 877 ESTs examined, 788 had significant matches in the chicken genome sequence. Position of orthologous sequences in the chicken genome and the predicted position of the EST loci in the turkey genome are presented Genetic assignments suggest a high level of accuracy for the COMPASS predictions.

    Full Text Available This paper analyzes the twin crises in Turkey experienced in 2000 and 2001. After a detailed survey of currency crisis models, together with a brief descriptive overview of the crises in Turkey, the similarities among the twin crises in Turkey and the models that have been developed to explain preceding crises in the world are investigated. It is found that the Turkish twin crises cannot be explained by using any individual generation of models, namely first generation models, second generation models or third generation models. Instead, a combination of these models is more appropriate to explain the details of the twin crises.

    Full Text Available The paper proposes to examine two variables in connection with the Kurdish presence in Turkey: 1 the intensity of expression of Kurdish nationalism, and 2 repercussions of the Kurdish question on Turkey. Three components pertaining to the Kurdish case in Turkey were constructed from the literature: distinct cultural identity, political demands and socio-economic development. The paper concludes that despite radical shifts on both sides, it is still questionable whether a solution to the enduring conflict could be reached in the near future.

  15. Determination of Genetic Variations of Toll-Like Receptor (TLR 2, 4, and 6 with Next-Generation Sequencing in Native Cattle Breeds of Anatolia and Holstein Friesian

    Full Text Available In recent years, the focus of disease resistance and susceptibility studies in cattle have been on determining patterns in the innate immune response of key proteins, such as Toll-like receptors (TLR. In the bovine genome, there are 10 TLR family members and, of these, TLR2, TLR4, and TLR6 are specialized in the recognition of bacterial ligands. Indigenous cattle breeds of Anatolia have been reported to show fewer signs of clinical bacterial infections, such as bovine tuberculosis and mastitis, and it is hypothesized that this might be due to a less stringent genetic selection during breeding. In contrast, Holstein-Friesian cattle have been under strong selection for milk production, which may have resulted in greater susceptibility to diseases. To test this hypothesis, we have compared the TLR2, TLR4, and TLR6 genes of Anatolian Black (AB, East Anatolian Red (EAR, South Anatolian Red (SAR, Turkish Grey (TG, and Holstein (HOL cattle using next-generation sequencing. The SAR breed had the most variations overall, followed by EAR, AB, TG, and HOL. TG had the most variations for TLR2, whereas SAR had the most variations in TLR4 and TLR6. We compared these variants with those associated with disease and susceptibility traits. We used exon variants to construct haplotypes, investigated shared haplotypes within breeds, and proposed candidate haplotypes for a disease resistance phenotype in Anatolian cattle breeds.

    The studied area is located in Western Anatolia and situated on the NE-SW directed Uşak-Güre cross-graben that developed under a crustal extensional regime during the Late Miocene-Pliocene. Silica occurrences have been mostly found as mushroom-shaped big caps. They also show sedimentary structures such as stratification. Silica occurrences are milky white, yellowish white, yellow to chocolate brown and rarely pale blue, bluish gray in color and have no crystal forms in hand specimen. Some of the silica samples show conchoidal fracture. Silica minerals are mostly chalcedony, low-quartz (α-quartz) and sporadically opal-CT in spectras, according to confocal Raman spectrometry. The silica samples have enrichment of Fe (1000-24,600 ppm), Ca (100-10,200 ppm), P (4-3950 ppm) and Mn (8-3020 ppm). Other striking elements in fewer amounts are Ba (0.9-609.6 ppm), Ni (15.7-182.3 ppm) and Co (18.6-343.1 ppm). In chondrite-normalized spider diagram, silica samples display partial enrichment in LIL elements (Rb, Ba, Th). The δ18O (‰ V-SMOW) values for silica samples vary from 18.4‰ to 22.8‰ and are similar to low temperature hydrothermal silica. Confocal Raman spectrometry and oxygen isotope indicate that the silica minerals may precipitate from host fluid which is relatively has low temperatures hydrothermal solutions derived from the residual melt of basaltic magma.

    Full Text Available Abstract Background The turkey (Meleagris gallopavo is an important agricultural species that is the second largest contributor to the world's poultry meat production. The genomic resources of turkey provide turkey breeders with tools needed for the genetic improvement of commercial breeds of turkey for economically important traits. A linkage map of turkey is essential not only for the mapping of quantitative trait loci, but also as a framework to enable the assignment of sequence contigs to specific chromosomes. Comparative genomics with chicken provides insight into mechanisms of genome evolution and helps in identifying rare genomic events such as genomic rearrangements and duplications/deletions. Results Eighteen full sib families, comprising 1008 (35 F1 and 973 F2 birds, were genotyped for 775 single nucleotide polymorphisms (SNPs. Of the 775 SNPs, 570 were informative and used to construct a linkage map in turkey. The final map contains 531 markers in 28 linkage groups. The total genetic distance covered by these linkage groups is 2,324 centimorgans (cM with the largest linkage group (81 loci measuring 326 cM. Average marker interval for all markers across the 28 linkage groups is 4.6 cM. Comparative mapping of turkey and chicken revealed two inter-, and 57 intrachromosomal rearrangements between these two species. Conclusion Our turkey genetic map of 531 markers reveals a genome length of 2,324 cM. Our linkage map provides an improvement of previously published maps because of the more even distribution of the markers and because the map is completely based on SNP markers enabling easier and faster genotyping assays than the microsatellitemarkers used in previous linkage maps. Turkey and chicken are shown to have a highly conserved genomic structure with a relatively low number of inter-, and intrachromosomal rearrangements.

    The structural evolution of Lake Van Basin, eastern Turkey, was reconstructed based on seismic reflection profiles through the sedimentary fill as well as from newly acquired multibeam echosounder data. The major sub-basins (Tatvan Basin and Northern Basin) of Lake Van, bound by NE-trending faults with normal components, formed during the past ~600 ka probably due to extensional tectonics resulting from lithospheric thinning and mantle upwelling related to the westward escape of Anatolia. Rapid extension and subsidence during early lake formation led to the opening of the two sub-basins. Two major, still active volcanoes (Nemrut and Süphan) grew close to the lake basins approximately synchronously, their explosive deposits making up >20 % of the drilled upper 220 m of the ca. 550-m-thick sedimentary fill. During basin development, extension and subsidence alternated with compressional periods, particularly between ~340 and 290 ka and sometime before ~14 ka, when normal fault movements reversed and gentle anticlines formed as a result of inversion. The ~14 ka event was accompanied by widespread uplift and erosion along the northeastern margin of the lake, and substantial erosion took place on the crests of the folds. A series of closely spaced eruptions of Süphan volcano occurred synchronously suggesting a causal relationship. Compression is still prevalent inside and around Lake Van as evidenced by recent faults offsetting the lake floor and by recent devastating earthquakes along their onshore continuations. New, high-resolution bathymetry data from Lake Van reveal the morphology of the Northern Ridge and provide strong evidence for ongoing transpression on a dextral strike-slip fault as documented by the occurrence of several pop-up structures along the ridge.

    The Bitlis-Pütürge Massifs and Derik volcanics that crop out in the Southeast Anatolian Belt are parts of the Cadomian domain in Anatolia where relicts of the oldest continental crust of Turkey are exposed. The Bitlis-Pütürge Massifs contain a Neoproterozoic basement, with overlying Phanerozoic rocks that were imbricated, metamorphosed and thrust over the edge of Arabia during the Alpine orogeny. The basement consists mainly of granitic to tonalitic augen gneisses and metagranites, associated with schists, amphibolites and paragneisses. Based on whole-rock geochemical data, the augen gneisses are interpreted to have protoliths crystallized from subduction zone magmas. This study conducted the first zircon dating on two augen gneisses that gave 206Pb/238U dates of 551 ± 6 and 544 ± 4 Ma, interpreted as the formation ages of the Pütürge Massif, broadly coeval to those of the Bitlis metagranites and the Derik volcanics that occurred from ca. 581 to 529 Ma (the Ediacaran-early Cambrian). The ɛHf(t) values (+1.2 to -5.3) of the dated zircons, with crustal model ages (TDMC) from 1.4 to 1.8 Ga, indicate that formation of the Pütürge Massif involves an older, most likely the Mesoproterozoic, continental crust component. Similar to the Bitlis-Pütürge gneisses, coeval basement rocks are widespread in the Tauride-Anatolide platform (e.g., the Menderes Massif). All these dispersed Cadomian basement rocks are interpreted as fragments of the Ediacaran-Early Cambrian continental arcs bordering the active margin of northern Gondwana.
