Abstract. In this study, the genetic diversity of three milk protein genes namely beta-casein, kappacasein and beta-lactoglobulin was estimated in Turkish cattle breeds. Based on these genes, breeds in Turkey have been grouped as: 1) Eastern Anatolian Red, Anatolian Black and Southern Anatolian Red and 2) Turkish Grey, Turkish Holstein and Holstein Candidate Bulls. B alleles of the three studied genes, which were reported to be positively related with cheese yield and quality, seemed to be low-intermediate for beta-casein and kappa-casein but relatively high for beta-lactoglobulin in the first group of Turkish breeds compared to other breeds of the world. The kappa-casein E allele, which has a negative effect on cheese quality, is absent in Turkish cattle breeds, except in Holstein Candidate Bulls. Therefore, the results suggest that milk of Turkish native breeds is suitable for cheese making. Based on observations of the Turkish breeds, some suggestions were made regarding breeding practices in Turkey.

Seasonal variability of the Caspian Sea three-dimensional circulation, sea level and air-sea interaction Ibrayev, R. A; Ozsoy, E; Schrum, C.; Sur, H. I. (Copernicus GmbH, 2010-3-3) <jats:p>Abstract. A three-dimensional primitive equation model including sea ice thermodynamics and air-sea interaction is used to study seasonal circulation and water mass variability in the Caspian Sea under the influence of realistic mass, momentum and heat fluxes. River discharges, precipitation, radiation and wind stress are seasonally specified in the model, based on available data sets. The evaporation rate, sensible and latent heat fluxes at the sea surface are computed interactively through an atmo...
Modeling dissolved oxygen dynamics and hypoxia Peña, M. A.; Katsev, S.; Oguz, T.; Gilbert, D. (Copernicus GmbH, 2010-3-9) <jats:p>Abstract. Hypoxia conditions are increasing throughout the world, influencing biogeochemical cycles of elements and marine life. Hypoxia results from complex interactions between physical and biogeochemical processes, which can not be understood by observations alone. Models are invaluable tools at studying system dynamics, generalizing discrete observations and predicting future states. They are also useful as management tools for evaluating site-specific responses to management scenarios. Here we ...
Modelling seasonal circulation and thermohaline structure of the Caspian Sea Gunduz, M.; Özsoy, E. (Copernicus GmbH, 2014-6-10) <jats:p>Abstract. The wind- and buoyancy-driven seasonal circulation of the Caspian Sea is investigated for a better understanding of its basin-wide and mesoscale dynamics, mixing and transport. The model successfully reproduces the following basic elements of the circulation: the southward-flowing current systems along the eastern and western coasts, the upwelling along the eastern coast, the cyclonic circulation in the Middle Caspian Sea (MCS), especially in winter, and the cyclonic and anticyclonic cells...
Validation of the operational MSG-SEVIRI snow cover product over Austria Surer, S.; Parajka, J.; Akyurek, Z. (Copernicus GmbH, 2014-2-24) <jats:p>Abstract. The objective of this study is to evaluate the mapping accuracy of the MSG-SEVIRI operational snow cover product over Austria. The SEVIRI instrument is aboard the geostationary Meteosat Second Generation (MSG) satellite. The snow cover product provides 32 images per day, with a relatively low spatial resolution of 5 km over Austria. The mapping accuracy is examined at 178 stations with daily snow depth observations and compared with the daily MODIS-combined (Terra + Aqua) snow cover produc...
Illitization of Late Devonian-Early Carboniferous K-bentonites from Western Pontides, NW Turkey: Implications for their origin and age BOZKAYA, ÖMER; Günal Türkmenoğlu, Asuman; Göncüoğlu, Mehmet Cemal; Unluce, Ozge; Yılmaz, İsmail Ömer; Schroeder, Paul A. (2016-12-01) K-bentonite (tephra) layers are exposed as thin beds within Late Devonian-Early Carboniferous carbonates of the Yilanh formation at four different locations in northwestern, Turkey. Clays separated from K-bentonites in the Gavurpman, Yilanh Burnu (Barth) and Cimsir Cukurlari (Sapca) quarries and the highway tunnel section near Zonguldak were analyzed by X-ray diffraction, optical, scanning and high-resolution transmission electron microscopy and inductively coupled plasma-mass spectrometry. The clay mineral...
