The Pertek granitoid consisting dominantly of diorite, quartz diorite, quartz monzodiorite, tonalite and lesser granite, adamellite and syenite, is considered to form the easternmost continuation of the Central Anatolian Crystalline Complex. Diorite and monzonites of this granitoid complex are cut by the granitic dykes. The Pertek granitoid, in the study area, is found in the Permo-Triassic Keban metamorphic sequence along intrusive and tectonic contacts. Along the intrusive contacts metasomatic mineralizations are common. Granitoids are, depending on the mineralogical composition, low-, middle- high-K subalkaline features. Major oxide-SiO2 variation diagrams show that fractionation (particularly plagioclase, hornblend, pyroxene and olivine fractionation) played an important role on the granitoid formation during a continuous crystallization process. Distribution of the samples from the Pertek granitoid in the tectonic setting diagrams, and their chondrite- and primordial mantle-normalized trace element patterns resemble to the of arc-type granitoids. Trace element and rare earth element compositions indicate that the magma, from which the Pertek granitoid crystallized, derived from a mantle that was enriched by the fluids derived from the subducted slab, however this magma was contaminated by the crust during its intrusion. These geochemical characteristics are also supported by the field observations. The field and geochemical characteristics of the Pertek Granitiod suggest that they are similar to the other granitoids cropping out in the central and eastern Anatolia and they form the lateral continuation of the same magmatic belt.

Aims: The current study aimed to evaluate the efficacy, side effects of radiotherapy and factors influencing treatment outcome in patients received radiotherapy for cerebral meningiomas. Methods and Material: In the last two decades, a total of 35 patients with cerebral meningioma who received radiotherapy in our clinic were evaluated statistically in terms of survival, toxicity and prognostic factors. The records of patients diagnosed with cerebral meningioma who underwent postoperative radiotherapy were retrospectively analyzed. Statistical analysis used: Statistical comparisons were made using IBM SPSS v24.0. Kaplan-Meier method was used to compare survival times. Results: Five of the patients had grade I meningioma showing recurrence, 18 were grade II meningioma and 12 were grade III meningioma. Patients were treated with 54 or 60 Gy adjuvant radiotherapy with 2 Gy daily fractions according to histopathological grade and operation type. Three and five-year overall survival rates were 56% and 40%, respectively and median overall survival was 36 months. Progression was observed in 15 of the 35 patients included in the study. Three and five-year progression-free survival (PFS) rates of the patients were 56% and 50%, respectively. There was a statistically significant correlation between histopathological grade and overall survival among patients. However;no statistical difference found in overall survival of patients in terms of tumor location, operation type and age. Conclusions: In the treatment of cerebral meningiomas, changes in radiotherapy dose and field designs can be predicted according to the tumor grade and operation type. In addition, it is thought that large scale studies are needed to determine prognostic factors more meticulously.

The complex of molybdenum (VI) with stilbene-2,2’-disulfonic acid-4,4’’bis (azo-1’’)-3’’, 4’’ dioxybenzene (stillbazo) in the presence of a cationic surfactant cetylpyridinium chloride (CPCl) was studied spectrophotometrically. It was found that in the presence of CPCl, a mixed-ligand complex with a component ratio of 1:2:4 is formed. The effect of pH, time, temperature, the concentration of reagents, and CPCl in the formation of homogeneous ligand and mixed-ligand complexes were studied. The stability constants (lgβk = 86 × 108) and the molar absorption coefficient of the mixed-ligand complex (εк = 11,835) were determined. It was found that Beer’s law is observed at a concentration of 0.05 - 17.00 μg/ml. A method has been developed for the spectrophotometric determination of molybdenum (VI) in complex industrial facilities.

Considering that an ethnic group becomes visible through culture, our study highlights some major themes of Tatar identity discourse in Dobrogea, with reference to cultural life and educational institutions. During the inter-war period, this ethnic community started the process of self-configuration and we intend to emphasize the role of education and culture for identity shaping. This paper will present cultural politics in Dobrogea, especially the role of the Muslim Seminary in Babadag/Medgidia in preserving the religion, language, and the cultural heritage of the Tatar community in Romania.

Somephysical properties of zinc-blende polytype of ZnS were investigated via geometry optimization calculations. After employing a shell model interatomic potential to our computations, some physical parameters such as typical cubic elastic constants, young modulus, shear modulus, bulk modulus, poisson ratio, elastic wave velocities, static and high frequency dielectric constants, and static refractive index zinc-blende ZnS were deduced. Later, previous theoretical results and our current results with each other as well as with former experimental findings were evaluated. Present results exhibit a fair consistency with experiments and better than those of several recent density functional theory results for the considered parameters of related material.

The aim of this study was to investigate increase of QTc dispersion and P-wave dispersion during migraine attacks. Fifty-five patients (16-65 years of age, 49 women, six men) with migraine were included in our study. Heart rate, QTc interval, maximum and minimum QTc interval, QTc dispersion, maximum and minimum P-wave duration and P-wave dispersion were measured from 12-lead ECG recording during migraine attacks and pain-free periods. ECGs were transferred to a personal computer via a scanner and then used for magnification of ×400 by Adobe Photoshop software. Maximum QTc interval (454 ±24 ms vs. 429 ±23 ms, P < 0.001), QTc interval (443 ±26 ms vs. 408 ±22 ms, P < 0.001) and QTc dispersion (63 ±18 ms vs. 43 ±14 ms, P < 0.001) were found significantly higher during migraine attacks compared with pain-free periods. Maximum P-wave duration (107 ±11 ms vs. 100 ±11 ms, P < 0.001) and P-wave dispersion (45 ±13 ms vs. 35 ±13 ms, P < 0.001) were found higher during migraine attacks than pain-free periods. We concluded that migraine attacks are associated with increased QTc and P-wave dispersion compared with pain-free periods.
