Abstract. A simulation of the Turkish Straits System (TSS) using a high-resolution, three-dimensional, unstructured mesh ocean circulation model with realistic atmospheric forcing for the 2008–2013 period is presented. The depth of the pycnocline between the upper and lower layers remains stationary after 6 years of integration, indicating that despite the limitations of the modelling system, the simulation maintains its realism. The solutions capture important responses to high-frequency atmospheric events such as the reversal of the upper layer flow in the Bosphorus due to southerly severe storms, i.e. blocking events, to the extent that such storms are present in the forcing dataset. The annual average circulations show two distinct patterns in the Sea of Marmara. When the wind stress maximum is localised in the central basin, the Bosphorus jet flows to the south and turns west after reaching the Bozburun Peninsula. In contrast, when the wind stress maximum increases and expands in the north–south direction, the jet deviates to the west before reaching the southern coast and forms a cyclonic gyre in the central basin. In certain years, the mean kinetic energy in the northern Sea of Marmara is found to be comparable to that of the Bosphorus inflow.

Effects of microwave and ultrasonic extraction methods on total phenolic content of nettle (Urtica diocia) Ince, Alev Emine; Şahin, Serpil; Sumnu, Gulum (null; 2011-12-01) Abstract. Effects of different extraction methods at different conditions on total phenolic content (TPC) of nettle (Urtica diocia) were investigated. Water was used as solvent. TPC analysis was performed according to Folin-Ciocalteu method. In microwave extraction, heating was achieved using microwaves at 407W power level. Effects was obtained as 1:30 solid-to-solvent ratio for 10min. Extraction was also performed conventionally at 1:30 solid-to-solvent ratio for 30min for comparison. There was no signific...
Near real-time estimation of ionosphere vertical total electron content from GNSS satellites using B-splines in a Kalman filter Erdogan, Eren; Schmidt, Michael; Seitz, Florian; Durmaz, Murat (Copernicus GmbH, 2017-2-27) Abstract. Although the number of terrestrial global navigation satellite system (GNSS) receivers supported by the International GNSS Service (IGS) is rapidly growing, the worldwide rather inhomogeneously distributed observation sites do not allow the generation of high-resolution global ionosphere products. Conversely, with the regionally enormous increase in highly precise GNSS data, the demands on (near) real-time ionosphere products, necessary in many applications such as navigation, are growing very fas...
Reviewing the Implementation of Life Sciences Curriculum in Turkey Using Elicitation Techniques Engin Demir, Cennet (2018-06-01) Abstract. The aims of this case study were (1) to investigate the general characteristics of the Life Sciences Curriculum (LSC); (2) to examine how the LSC is implemented in a public primary school from the perspectives of teachers, students and administrators; and (3) to identify whether implementation of the curriculum was in line with the principles of constructivist pedagogy. The study participants consisted of the school administrator, 2 co-administrators, 4 classroom teachers and 87 students fr...
EVALUATION OF NUSSELT NUMBER FOR A FLOW IN A MICROTUBE USING SECOND-ORDER SLIP MODEL Cetin, Barbaros; Bayer, Özgür (National Library of Serbia, 2011-01-01) In this paper. the fully-developed temperature profile and corresponding Nusselt value is determined analytically for a gaseous flow in a microtube with a thermal boundary condition of constant wall heat flux. The flow assumed to be laminar, and hydrodynamically and thermally fully developed. The fluid is assumed to be constant property and incompressible. The effect of rarefaction, viscous dissipation and axial conduction, which are important at the microscale, are included in the analysis. Second-order sl...
DETERMINANTS OF TURKEY'S TRADE FLOWS: GRAVITY MODEL APPROACH Bilici, Oe; Erdil, Erkan; Yetkiner, H. (2011-01-01) This paper aims to determine (i) the trade flow equation for Turkey by using the gravity equation, (ii) the role of EU in Turkey's trade and whether the Customs Union of EU that Turkey entered in 1996 made a deviation in Turkey's trade flows. Turkey was a closed economy in late 1970s and has gradually become an open economy in these 30 years. During this period, Turkey followed globalization and regional integration strategies simultaneously. On the one hand, Turkey gradually opened its economy to the rest ...
