Yamac E. & Bilgin C.C. 2012. Post-fledging movements of Cinereous Vultures Aegypius monachus in Turkey revealed by GPS telemetry. Ardea 100: 149-156. We studied the movements, home ranges and roost site preferences of three first-year Cinereous Vultures Aegypius monachus after they fledged at the Turkmenbaba Mountains, Eskisehir, western Turkey. We captured chicks at the nest in 2009 and 2010 and fitted them with GPS-GSM transmitters. After fledging, we received a total of 993 locations from all birds during 105-148 days of tracking. Tracked birds initially used small foraging areas, covering a mean 90% kernel home range of 356 +/- 134 SE km(2), and on average moved <10 km per day. As they started to migrate, daily movements increased to 59.3-120.3 km on average and took place largely during midday. Birds preferred to roost at sites with higher altitude, steeper slope and more wooded land. Our data suggest that first-year birds from Turkey disperse south in October and November to desert habitats in middle latitude Arabia, and may cover up to 2765 km during migration.

X-Ray Timing Properties of GX 1+4 Serim, Muhammed Miraç; Sahiner, Seyda; Serim Cerri, Danjela; Inam, Sitki Cagdas; Baykal, Altan (2016-10-14) We present timing analysis of accreting X-ray pulsar GX 1+4 using the RXTE-PCA observations between 2001 and 2002. By constructing a phase connected timing solution for the source, we measured their spin frequencies and updated the long-term pulse frequency history of this source. We also reviewed the relation between frequency derivative and X-ray flux during this episode.

Synthesis and characterization of fluorine-substituted polyanilines Cihaner, A; Önal, Ahmet Muhtar (Elsevier BV, 2001-09-01) Poly(2-fluoroaniline), P2FAN, poly(3-fluoroaniline). P3FAN. and poly(4-fluoroaniline), P4FAN, have been synthesized from fluorine substituted aniline monomers in aqueous acidic medium using potassium dichromate as oxidizing agent. Characterization of polymer products has been carried out using FTIR, and NMR spectroscopic techniques. Thermal analysis of polyfluoroaniline powders was also investigated using differential scanning calorimetry and thermogravimetric analysis. To compare the structural properties ...
An investigation of bacterial and fungal xylanolytic systems Yaşınok, Ayşegül Ersayın; Bakır, Ufuk; Department of Biotechnology (2006) Endo-b-1,4 xylanases (EC. 3.2.1.8) are typically produced as a mixture of different hydrolytic enzymes such as b-1,4-xylosidase (EC. 3.2.1.37) , a-Larabinofuranosidases (EC. 3.2.1.55), and feruloyl esterase (EC 3.1.1.73) that hydrolyze xylan molecule, which constitutes 20-30% of the weight of wood and agricultural wastes. Thus, xylan, a renewable biomass, can be utilized as a substrate for the preparation of many products such as fuels, solvents and pharmaceuticals. Besides, xylanolytic enzymes themselves a...
Genetic diversity of marginal populations of Populus euphratica Oliv. from highly fragmented river ecosystems Kansu, Çiğdem; Kaya, Zeki (2020-01-01) Populus euphratica Oliv. (Euphrates poplar) is one of the naturally distributed poplar species and limited to south and southwestern Turkey. The species possesses great importance for both renewable energy resources and persistence of a healthy river ecosystem. Due to increased habitat destructions and fragmentation by human activities, the distribution area of this species has become narrower. Hence, searching for potential genetic diversity present in species' genetic resources is of great importance in t...
