    Geochemical and Sr-Nd isotopic characteristics of post-collisional calc-alkaline volcanics in the eastern Pontides (NE Turkey)

    Arslan, Mehmet; Şen, Cüneyt; Kaygusuz, Abdullah; Siebel, Wolfgang

    Doğu Pontidlerde Eosen yaşlı Torul volkanitlerinin ana, iz element, K-Ar yaş ve Sr-Nd izotop verileri incelenmiştir. İncelenen volkanitler, bazaltik andezit, andezit, trakiandezit ve az oranda da trakidasit ve bunların piroklastiklerinden oluşurlar. Volkanitler plajiyoklas (An2–44), hornblend (Mg#= 0.78–0.98), klinopiroksen (Wo ₄₃₋₄₆ En ₄₁₋₄₃ Fs ₁₀₋₁₅), biyotit, kuvars ve az oranda da sanidin fenokristallerinden oluşurlar. Hornblendlerdeki K-Ar yaşları, 43.99 (±2.59) – 33.45 (±2.32) My aralığında olup, Torul volkanitlerinin Orta–Geç Eosen zamanında oluştuklarını göstermektedir. Torul volkanitleri kalk-alkalen karakterli olup orta–yüksek K içeriğine sahiptirler. Volkanitler büyük iyon yarıçaplı elementler (LILE) ve hafif hafif nadir toprak elementlerce (LREE) zenginleşmiş, yüksek çekim alanlı elementlerce (HFSE) tüketilmişlerdir. Kondrite normalize edilmiş nadir toprak element dağılımları, düşük–orta derecede zengileşmeyle konkav şekilli olup (La _cn/Lu _cn= 4.0–9.8), volkanitleri oluşturan kayaçların benzer kaynaktan itibaren oluştuklarını düşündürmektedir.⁸⁷Sr/⁸⁶Sr(i) değerleri 0.70457–0.70511 arasında olup ¹⁴³Nd/¹⁴⁴Nd(i) değerleri 0.70457–0.70511 arasındadır. Volkanitlerin gelişiminde başlıca fraksiyonel kristallenme, daha az oranda da kabuksal kirlenme ± magma karışımı rol oynamıştır. Tüm bu veriler, volkanitlerin köken magma(lar)sının muhtemelen daha önceki yitim akışkanları tarafından metasomatizmaya uğratılmış zenginleşmiş bir üst manto kaynağından, çarpışma sonrası jeodinamik bir ortamda türeyebileceklerini ifade etmektedir.

    Formation of skarns at Gumushane (Northeastern Turkey)

    Sipahi, Ferkan

    Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the skarn occurrence at Camibogazi dolomitic limestone, adjacent to the Eocene Zigana Granitoid. The prograde textures include rhythmic banding, spots, and mossiness, and the retrograde textures are shock-induced and brecciated. These are identified in the Fe skarn deposit at Arnastal, where there are mineral parageneses of andradite, actinolite, tremolite, epidote, quartz, magnetite, and hematite, and less pyrrboune and pyrite. Additionally, well-crystallized vesuvianite, well-crystallized phlogopite, and diopside in the skarn occurrence. at Camibogazi are identified. Some of the skarn minerals are calcic and have high Mg/(Mg + Fe) ratios. Clinopyroxene consists of diopside (Di(96.66-99.04)Hd(0.67-2.80)Jo(0.29-0.55)). Vesuvianite is mostly Mg-rich, and has a very low MnO content (<0.1 %). Other skarn minerals are Fe-rich. Garnet is characterized by oscillatory zoning and has an andradite composition (Ad(72)Gr(28) to Ad(98)Gr(2)). Epidote has an Fe content of 8.96 to 12.42 wt%. Magnetite is generally massive and sporadically banded with some martitization. The formation temperatures of skarn minerals range from 330 to 600 degrees C. In addition, mass change calculations from the granitoid and andesite toward the skarn zone indicate that there is considerable mass transfer of Si, Al, Fe, and Mg to the carbonate rocks during skarn formation. The average mass changes are estimated at a depletion of 41 g/100 g in granitoid and a gain of 8 g/100 g in andesite. Fe skarn deposit and skarn occurrence are characterized by early, high-temperature mineral assemblages dominated by the anhydrous minerals garnet and diopside and late low-temperature assemblages with hydrous minerals, such as vesuvianite, phlogopite, and epidote. The type of garnet and the abundance of magnetite with minor pyrite suggest that the Fe skarn deposit at Arnastal forms under relatively oxidized conditions. The type of clinopyroxene in the skarn occurrence at the Camibogazi shows oxidized skarns.

    A slab detachment and delamination model for the generation of Carboniferous high-potassium I-type magmatism in the Eastern Pontides, NE Turkey: The Kose composite pluton

    Dokuz, Abdurrahman

    The Hercynian Kose composite pluton (KCP) is located in the Eastern Pontides, Turkey, and consists of two units of high-K calc-alkaline, primarily peraluminous granites: (i) the internal body, and (ii) the external body. The internal body, which was emplaced at 322-318 Ma ((40)Ar/(39)Ar ages on biotite and hornblende, respectively), displays a wide compositional range (49-71 wt.% SiO(2)) and contains several lithologies: hybrid equigranular rocks, microgranular magmatic enclaves, mafic dikes, porphyry dikes and mylonites. The external body, which was emplaced at 306.7 Ma ((40)Ar/(39)Ar age on K-feldspar), consists exclusively of monzogranite (> 71 wt.% SiO(2)). Field relationships, mineralogy, major- and trace element geochemistry, and initial Sr-Nd isotope values (I(sr)= 0.70821 to 0.71002, e(Nd)(t) = -6.6 to -8.0) show that the internal body was differentiated and evolved by crystal fractionation and magma mixing processes. The end-members of the mixing process were a mafic rock and a felsic rock. Mafic magma was derived from a relatively deep-seated (25-30 km) crustal storage reservoir, not directly from the mantle, and underwent significant differentiation by fractional crystallization and crustal contamination before mixing. In addition, these magma storages probably supplied the additional heat necessary to initiate crustal melting. Some of the additional heat may have also been released by the radiogenic decay of heat producing elements. Eventually, the existing felsic magma from the melting of K-bearing meta-greywackes was raised to its emplacement level at a depth of similar to 10-16 km. After partial crystallization, it was sporadically intruded by modified mafic magma from the deeper crustal reservoir to generate hybrid rocks. The hybrid rocks were then elevated to a shallower depth by normal faults during the collapse of the orogen and erosion. Mylonites that were later overprinted by pseudotachylites are typically constrained to the internal body and are regarded as markers of this event. The external body is characterized by a significantly less radiogenic and limited range of Sr-Nd isotope values (I(sr)= 0.70639 to 0. 70792, e(Nd)(t) = -4.4 to -6.5) than those of the internal body and a lack of rocks documenting the open system differentiation processes. Fractional crystallization is the exclusive process responsible for the elemental range within the body. The rocks also contain less biotite relative to those of the internal body. All these involve less K-bearing mid-crustal rocks (orthogneisses) in their source, which was probably located at depths near the lower crust. The absence of purely lower crustal-derived melts can be explained by the removal of this type of material during the formation of the parental melt. This melt later ascended to its emplacement level at a depth of around similar to 5-10 km and cut the hybrid rocks of the internal body and regional metamorphic rocks that had been raised previously due to ongoing erosion. The melt that injected into the cracks of the internal body crystallized into porphyries because there was not enough time for the entire crystallization of magma. The data presented here indicate that late Early Carboniferous and Late Carboniferous magmatism occurred in a collisional setting. Slab detachment and subsequent delamination seem to be the most plausible mechanisms for the generation of the Hercynian high-K calc-alkaline magmatism in the Eastern Pontides, Turkey.

    Abrasion Resistance of Cement Mortar with Different Pozzolanic Compositions and Matrices

    Yetgin, Sukru; Çavdar, Ahmet

    Abrasion of concrete occurs due to scraping, rubbing, skidding, or sliding of objects on its surface. The abrasion resistance of concrete is influenced by a number of factors, such as compressive strength, surfacing finish, aggregate properties, types of hardeners, and curing. The main objective of this study is to determine the effects of the pozzolanic compositions and matrix structure (or voids) on the abrasion resistance of cement mortars. In this study, the mortars produced with cement samples with seven different compositions and varied with an air-entraining agent were subjected to the abrasive effects. Several examples of mortars were evaluated using samples cured for six different periods throughout 1 year. This study is supported by thin section investigations, in addition to being subjected to the basic tests, such as compression, flexure, and abrasion. The Bohme apparatus was used during abrasion tests. To summarize the most important findings from this study, a compact cement matrix is more effective against abrasive effects than mineral additives.

    Thermodynamic, performance and emission investigation of a diesel engine running on dimethyl ether and diethyl ether

    Sezer, Ismet

    This study investigates the use of dimethyl ether and diethyl ether in diesel engines as alternative fuels. A direct injection diesel engine was simulated via a thermodynamic cycle model for investigation. Thermodynamic and performance parameters besides emissions determined and compared for diesel, dimethyl ether and diethyl ether fuels at two different states. The results showed that dimethyl ether and diethyl ether presented a lower cylinder temperature and pressure, and thus a lower engine performance than diesel fuel for the equal injection conditions. The brake power declines about 32.1% and 19.4% at 4200 rpm while brake specific fuel consumption increases about 47.1% and 24.7% at 2200 rpm for dimethyl ether and diethyl ether, respectively. Engine performance for dimethyl ether and diethyl ether extensively improves for the same equivalence ratio condition, but a more amount of fuel is needed about 64% for dimethyl ether and 32% for diethyl ether. The gains in the brake power by dimethyl ether and diethyl are about 13.6% and 6% at 4200 rpm compared to diesel fuel. The brake specific fuel consumption is also higher about 43.5% for dimethyl ether and 23.6% for diethyl ether than diesel fuel. The brake thermal efficiency for dimethyl ether and diethyl is generally better than diesel fuel. The lower carbon dioxides are obtained by dimethyl and diethyl ethers at all conditions, while carbon monoxide and nitrogen oxide are slightly higher for dimethyl and diethyl ethers at equal equivalence ratio condition.

    Finite element model calibration effects on the earthquake response of masonry arch bridges

    Sevim, Baris; Bayraktar, Alemdar; Altunisik, Ahmet Can; Atamtürktür, Sezer; Birinci, Fatma

    The focus of this paper is to illustrate the importance of model calibration and in situ vibration testing by comparing the finite element model predictions of the earthquake response of the two historical arch bridges, Osmanli and Senyuva, before and after model calibration. The three-dimensional finite element models of these two arch bridges, built in the ANSYS finite element program, are used to predict bridge dynamic characteristics, such as natural frequencies and mode shapes. Following the analytical study, ambient vibration tests were conducted to experimentally obtain dynamic characteristics of these two bridges. During ambient vibration tests, accelerometers were placed at several points on the bridge to collect the vibration response due to natural and operational excitation sources. Enhanced frequency domain decomposition and stochastic subspace identification techniques were used to extract the experimental natural frequencies, mode shapes and damping ratios. Finite element models of the two arch bridges were adjusted such that the model predictions reproduce the ambient vibration test results with increased fidelity. The behavior of the masonry arch bridges under earthquake excitation recorded during the Erzincan Earthquake in 1992 is simulated by both the initial and adjusted finite element models. The findings of this study emphasize the importance of model calibration and ambient vibration testing. (C) 2010 Elsevier B.V. All rights reserved.

    Weight minimization of trusses with genetic algorithm

    Dede, Tayfun; Bekiroglu, Serkan; Ayvaz, Yusuf

    This study is concerned with encoding types such as value encoding and binary encoding for continuous and discrete optimization with a GA, which is coded in FORTRAN and considers stress and displacement constraints, in view of weight minimization of truss structures. Moreover, when continuous optimization is performed, the challenge of huge search space due to the effort of considering continuous set of design variables is overcame by a mechanism introduced as restricted range approach (RRA) in this study. In comparison with the literature, it is concluded that the program developed in this study can be effectively used in the weight minimization of truss structures. It is also came to the conclusion that value encoding overcomes the adverse effects of Hamming-cliff, and that value encoding requires less computer memory and time, never destroys the fit chromosome.

    An Atropa belladonna L. poisoning with acute subdural hematoma

    Cikla, Ulas; Turkmen, Suha; Karaca, Yunus; Ayaz, Ahmet Faik; Turedi, Suleyman; Gunduz, Abdulkadir

    Atropa belladonna L. is a plant long known to cause poisoning. But no cases of acute subdural hematoma resulting from such poisoning have been reported so far. Care must also be taken in terms of acute pancreatitis and rhabdomyolysis in cases of such poisoning. The plant may sometimes be mistaken for the Caucasian blueberry, V. arctostaphylos L. At least one anti-cholinesterase toxidrome finding was determined in all the nine cases of belladonna poisoning in this series. No elevated creatine kinase was reported in one case with acute subdural hematoma and hyperamylasemia.

    Assessment of natural radioactivity and mass attenuation coefficients of brick and roofing tile used in Turkey

    Damla, N.; Cevik, U.; Kobya, A. I.; Celik, A.; Celik, N.; Yildirim, I.

    In this study the distribution of natural radionuclides ((226)Ra, (232)Th, (40)K) in brick and roofing tile samples commonly used as building materials in Turkey was measured by using gamma spectrometry. The activity concentrations, radium equivalent activities (Ra(eq)), representative level index, indoor absorbed dose rate in air values and annual effective dose due to the intake of the above-mentioned radionuclides in the brick and roofing tile samples were estimated to assess the radiation hazard for people living in dwellings made of the materials studied. The measured average activity concentrations of (226)Ra, (232)Th and (40)K were 34 +/- 14, 34 +/- 13 and 462 +/- 175 Bq.kg(-1), respectively, for brick samples. For roofing tile, the average activity concentrations of (226)Ra, (232)Th and (40)K were measured to be 34 +/- 14, 33 +/- 12 and 429 +/- 161 Bq.kg(-1), respectively. The concentrations for these natural radionuclides were compared with the reported data of other countries. The Ra(eq) values of all samples were lower than the limit of 370 Bq.kg(-1), equivalent to a gamma dose of 1.5 mSv.a(-1) recommended by OECD. This study shows that the measured brick and roofing tile samples do not pose any significant source of radiation hazard and are safe to be used as building materials. Moreover, the experimental mass attenuation coefficients (mu/rho) of brick and roofing tile samples were determined in the energy range 80-1332 keV using the gamma ray transmission method. The experimental mass attenuation coefficients were compared with theoretical values obtained using XCOM. It was found that the computed values and the experimental results of this work are in good agreement with those reported in the literature. The chemical compositions and structural analysis (XRD) of the brick and roofing tile samples are also presented. (C) 2011 Elsevier Ltd. All rights reserved.

    Sexual function in male patients with ankylosing spondylitis

    Özkorumak, E.; Karkucak, M.; Civil, F.; Tiryaki, A.; Özden, G.

    Sexuality is an important part of healthy life. Patients with ankylosing spondylitis (AS) may be vulnerable to sexual problems because of disease activity and comorbid emotional problems. However, sexuality is a scarcely studied subject in AS. The aim of this study is to compare patients with AS with healthy control. A total of 43 male patients, who referred to the Department of Physical Medicine and Rehabilitation Clinics of the Karadeniz Technical University Farabi Hospital between May 2010 and July 2010, and were diagnosed as AS according to modified New York criteria, were included in the study. Control group consisted of healthy 43 age-and sex-matched male individuals with normal inflammatory levels. The AS patients were compared in means of sociodemographic variables and sexual function with Glombok-Rust Sexual Satisfaction Scale (GRSSS) and clinical interview. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were used to determine anxiety and depression levels, respectively. The disease activity and functional conditions were evaluated with the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath Ankylosing Spondylitis Metrology Index (BASMI) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDI). A total of 43 patients with AS and 43 healthy heterosexual male were included in the study. The total GRSSS score was significantly higher in patients with AS, whereas they also had significantly higher sexual complaint than healthy control. The diagnosis of sexual dysfunction according to DSM-IV was significantly higher in the patients with AS as well as depression and anxiety. In study group, GRSSS total score was modestly correlated with disease activity. The psychological status had close relation with sexual functions in AS. Overall assessment is required for complete evaluation in patients with AS. International Journal of Impotence Research (2011) 23, 262-267; doi: 10.1038/ijir.2011.37; published online 4 August 2011

    Finite element model updating effects on nonlinear seismic response of arch dam-reservoir-foundation systems

    Bayraktar, Alemdar; Sevim, Baris; Altunisik, Ahmet Can

    This paper investigates the effects of finite element model updating on nonlinear seismic response of arch dam-reservoir-foundation systems. The highest arch dam in Turkey named Berke is selected for the numerical and experimental applications. Firstly, 3D finite element model of Berke Dam was constituted using an ANSYS software. In the analytical modeling, arch dam-reservoir-foundation interaction is represented by Lagrangian approach. Then ambient vibration tests were conducted to dam for four days, and experimental dynamic characteristics were estimated using an Enhanced Frequency Domain Decomposition technique. Experimental characteristics are compared with those of analytical obtained by the linear finite element analysis of the coupled system. Good agreement between mode shapes is observed during this comparison, though natural frequencies disagree by 15-20%. The linear finite element model of Berke Dam was updated by adjusting the material properties of the dam and foundation. By introducing the Drucker-Prager damage criterion, the updated linear finite element model was extended into an onlinear model. Nonlinear seismic behavior of Berke Dam was determined considering the acceleration record of Adana-Ceyhan, Turkey, earthquake in 1998 that occurred near the arch dam region. It is highlighted that the finite element model updating provides a significant influence on the nonlinear seismic response of arch dams. (C) 2010 Elsevier B.V. All rights reserved.
