Hall Effect On Mhd Forced Convection From An Infinite Porous Plate With Dissipative Heat In A Rotating System, Nazibuddin Ahmed, Jiwan Krishna Goswami
Hall Effect On Mhd Forced Convection From An Infinite Porous Plate With Dissipative Heat In A Rotating System, Nazibuddin Ahmed, Jiwan Krishna Goswami
Turkish Journal of Physics
An attempt has been made to study the Hall effect on MHD forced convection from an infinite horizontal porous plate with dissipative heat in a rotating system with uniform free stream when the temperature at the plate varies periodically with time. The entire system rotates with a constant angular velocity about the normal to the plate. A uniform magnetic field is assumed to be applied along the normal to the plate directed into the fluid region. The governing equations are solved analytically. The expressions for the velocity and temperature field are obtained in non-dimensional form. The skin friction due to …

Turkish Journal of Earth Sciences
The basement rocks located in the central part of the southern edge of the Küçük Menderes Graben, around Akçaşehir-Tire are composed of marbles, schists, gneisses and metagabbros of the Ödemiş-Kiraz submassif of the Menderes Massif, and schists, marbles and meta-olistostromes of the Cycladic Complex. The basement is unconformably overlain by Neogene-Quaternary continental sediments. These continental basin fills are comprised of the Ayaklıkırı Formation, the Aydoğdu Formation and alluvium that unconformably overlies them. The Lower-Upper Miocene Ayaklıkırı Formation consists of lacustrine and fluvial deposits. The Plio-Pleistocene (?) Aydoğdu Formation is made up of alluvial fan deposits.

The Gümüldür Fire Opal: Mode Of Occurrence And Mineralogical Aspects, Zeki̇ye Karacik, Şengül Can Genç, Recep Fahri̇ Esenli̇, Gülteki̇n Göller
Turkish Journal of Earth Sciences
Five types of silica polymorphs have been identified in dacitic volcanics from the Gümüldür region of western Anatolia, Turkey. Two of them are micro-quartz and disordered cristobalite (opal-C) that occur within the groundmass of the dacitic volcanic rocks. The others are pore-filling opal nodules including mainly massy opal-CT (opal-CTM) and rarely lussatite (opal-CTL) and amorphous opal (opal-A). Red and orange opal nodules are very similar to the gemologically well-known fire opals. Results of structural, chemical and thermal studies of the Gümüldür opals reveal their origin and mode of occurrence. Opal-CTM has gel-like or nano-grain texture and opal-CTL has a fibrous, …

First Records Of Late Devonian Entomozoacean Ostracods In North-Western Turkey, Ati̇ke Nazi̇k, Helga Groos-Uffenorde
Turkish Journal of Earth Sciences
Entomozoacean ostracods (pelagic socalled fingerprint-ostracods) have recently been observed for the first time in Upper Devonian sediments of the Darlık B Section from the İstanbul region, north-western Turkey. These new assemblages consist of Entomoprimitia nitida, Entomoprimitia sartenaeri, Entomoprimitia concentrica, Franklinella calcarata, Waldeckella erecta?, Rabienella n. sp. c, aff. reichi sensu Rabien & Rabitz 1958, Rabienella reichi, Richterina (Volkina) zimmermanni and Nehdentomis pseudorichterina and can be dated as Late Frasnian Entomoprimitia sartenaeri Zone (= variostriata Zone sensu Rabien 1954). These entomozoacean ostracods indicate a faunal relationship with Germany (Rhenish Schiefergebirge, Harz Mountains, Thuringia), Poland (Holy Cross Mountains), N France-Belgium (Ardennes), Volgo-Ural …

Geodynamic Significance Of The Early Triassic Karaburun Granitoid (Western Turkey) For The Opening History Of Neo-Tethys, Cüneyt Akal, Osman Ersi̇n Koralay, Osman Candan, Oberhaensli Roland, Fukun Chen
Turkish Journal of Earth Sciences
The Karaburun Peninsula, which is considered part of the Anatolide-Tauride Block of Turkey, contains clastic and carbonate sequences deposited on the northern margin of Gondwana. The Palaeozoic clastic sequence, which is intruded by the Early Triassic granitoid and tectonically overlies a Mesozoic mélange sequence, can be divided into three subunits: a lower clastic subunit consisting of a sandstone-shale alternation, an upper clastic subunit consisting of black chert-bearing shales, sandstone and conglomerate, and a Permo-Carboniferous carbonate subunit. The lower Triassic Karaburun I-type granitoid has a high initial ^8^7Sr/^8^6Sr ratio (0.709021-0.709168), and low ^1^4^3Nd/^1^4^4Nd ratio (0.512004-0.512023) and \epsilonNd (-5.34 to -5.70) isotopic …

Geology And Tectonic Emplacement Of Eclogite And Blueschists, Biga Peninsula, Northwest Turkey, Firat Şengün, Erdi̇nç Yi̇ği̇tbaş, İsmai̇l Onur Tunç
Turkish Journal of Earth Sciences
The Biga Peninsula in northwestern Anatolia is a tectonic mosaic, comprising different tectonic units, representing the Sakarya Continent and oceanic assemblages of different origin and ages. The Çamlıca metamorphic association, a member of this orogenic mosaic in the westernmost part of the peninsula, is subdivided into three formations, from bottom to top; the Andıktaşı formation, the Dedetepe formation, and the Salihler formation. Eclogite-facies metamorphic rocks occur as tectonic slices within schist-marble intercalations of the Dedetepe formation. These slices, about 2 km long and 500 m wide, include two different rock types; (i) quartz-mica schists, and (ii) metabasite lenses with eclogite/blueschist …

Geological And Palaeoseismological Evidence For Late Pleistocene−Holocene Activity On The Manisa Fault Zone, Western Anatolia, Çağlar Özkaymak, Hasan Sözbi̇li̇r, Bora Uzel, Hüsnü Serdar Akyüz
Turkish Journal of Earth Sciences
In West Anatolia near the cities of İzmir and Manisa, the historical occurrence of large earthquakes suggests the presence of important seismogenic faults. However, these faults have yet to be investigated in detail. The Manisa Fault Zone (MFZ) is an active large-scale normal fault system in this area, and thus field observations and palaeoseismological studies of this zone are important for predicting future earthquakes. Hence we sought to document geological and palaeoseismological evidence for Holocene activity on the MFZ. We performed trenching to determine the magnitude and timing of past surface-faulting events using detailed fault-trace mapping, measurements of Upper Pleistocene-Lower …

We aimed to determine whether there would be any oxidative stress effect of 50 Hz EF on developing spinal cord tissues of pup rats by evaluating malondialdehyde (MDA), nitric oxide (NO) levels, and antioxidant enzyme activities such as superoxide dismutase (SOD) and catalase (CAT) measurement. Materials and methods: In the prenatal+postnatal group, the pregnant rat was exposed to continuous EF at 50 Hz 10 kV/s until delivery. Then the female pups of this group (n = 7) were exposed to EF at the same doses …

Micropropagation And Root Culture Of Turkish Endemic Astragalus Chrysochlorus (Leguminosae), Semra Hasançebi̇, Nesli̇han Turgut Kara, Özgür Çakir, Şule Ari
Turkish Journal of Botany
Efficient micropropagation and root culture protocols were developed for the endemic Astragalus chrysochlorus Boiss. & Kotschy. A high frequency of shoot formation (100%) and maximum multiplication (13 shoots per hypocotyl explant) were achieved on Murashige and Skoog (MS) media supplemented with 0.5 mg/L trans-Zeatin riboside (ZR). By using single regenerated hypocotyl explants, rooting was achieved at a rate of 93% on MS medium containing 2% sucrose without growth regulators. High frequency callus initiation and growth were achieved when single hypocotyl explants were inoculated on MS medium supplemented with 0.5 mg/L 2,4-Dichlorophenoxyacetic acid. Plant regeneration through indirect organogenesis was achieved on …

Turkish Journal of Botany
This study was carried out to investigate the relationship between in vitro competition and stress, and their effects on tissue culture response of Linum usitatissimum L. hypocotyl explants. Competition among explants was achieved by varying the spacing among the explants cultured. Four different culture spacing distances were used: 0.5, 1.0, 1.5, and 2.0 cm. Six weeks after culture initiation, hypocotyl fresh and dry weights, shoot regeneration percentage, shoot number per hypocotyl, regenerated shoot length, total shoot number per petri dish, and total chlorophyll content were recorded. The results showed that encouraging competition among explants by decreasing spacing among them from …
