    Farklı ayrışma derecesine sahip kaya kütlelerinin kazılabilirlik özellikleri: Gümüşhane Granitoyidi örneği, Gümüşhane, KD Türkiye

    Dağ, Serhat; Kaya, Ayberk; Gurocak, Zulfu; Alemdag, Selcuk

    Kayaların kazılabilirlik özelliklerini belirlemek amacıyla yapılacak çalışmalar kazı maliyeti açısından mühendislik projelerinin uygulanabilirliğine katkı sağlamaktadır. Bu çalışmada, Gümüşhane ve yakın yöresinde yüzeylenen Erken Karbonifer yaşlı Gümüşhane Granitoyidi’nin kazılabilirlik özellikleri incelenmiştir. İlk olarak, dört faklı alan seçilmiş ve bu alanlardaki kaya kütleleri ISRM tanımlama kriterleri esas alınarak ayrışma derecelerine göre gruplandırılmıştır. Bu çalışmalar sonucunda 1, 2 ve 3 numaralı alanlardaki kaya kütlelerinin orta derecede ayrışmış, 4 numaralı alandaki kaya kütlesinin ise ileri derecede ayrışmış kaya sınıfında olduğu tespit edilmiştir. İkinci aşamada, eklemlerin mühendislik özellikleri ve kaya malzemesinin jeomekanik özellikleri belirlenmiştir. Sonraki aşamada ise kaya kütlelerinin RMR89, Q ve GSI değerleri belirlenmiş ve kazılabilirlik açısından sınıflandırılmıştır. Yapılan sınıflamalara göre, orta derecede ayrışmış kaya kütleleri “sökülebilir”, ileri derecede ayrışmış kaya kütlesi ise “kazılabilir” özelliktedir. İnceleme alanlarında yapılan kazı çalışmalarında orta derecede ayrışmış kaya kütlelerinin hidrolik kırıcı kullanılarak söküldüğü, ileri derecede ayrışmış kaya kütlelerinin ise kepçe kullanılarak kazıldığı tespit edilmiştir. Son aşamada ise bulunan sonuçlar ile uygulanan kazı yöntemleri karşılaştırılmıştır. Bu sonuçlara göre, Tsiambaos ve Saroglou (2009) tarafından önerilen kazı yöntemleri, yerinde yapılan kazı çalışmaları ile tamamen örtüşmektedir.

    Kur’an’da Hz. Muhammed’e yapılan ikazlar

    Öz, Ahmet

    Allah, Hz. Âdem’den son peygamber Hz. Muhammed’e kadar geçen süre içinde, insanları doğru yola iletmeleri ve yanlışlardan uzaklaştırmaları için kendi içlerinden peygamberler görevlendirmiştir. Peygamberler, örnek insanlar oldukları için günahlardan uzak durmuşlardır. Allah onların bazı yanılgılarını da uyararak düzeltmiştir. Eğer düzeltmeseydi onlar bizim için güzel örnek olamazlardı. Allah, Kur'an-ı Kerim’de, Hz. Peygamber’in bazı yanılgılarından bahsetmiş ve bu davranışlarından dolayı uyarılarda bulunmuştur. Bu uyarılar, bazen onun vahyin gelmesini beklemeden erken davranması, bazen de iyi niyetlerle yaptığı birtakım davranışlar neticesinde düştüğü yanılgılar için yapılmıştır. Sonuçta O, bu uyarılar neticesinde, hemen doğru olanı tercih etmiş ve tekrar aynı yanılgıya düşmemiştir. Bu çalışmamızda biz, Hz. Muhammed’in bir insan olduğundan hareketle, onun da zaman zaman yanılabildiğini, fakat bu yanılmaların, Allah tarafından uyarılarak düzeltildiğini ifade etmeye çalıştık.

    “Sports activities” As a ground of justification in Islamic penal legislation

    Telkenaroğlu, M. Rahmi

    Islam has allowed sports activities that give physical strength and skill toindividuals and benefits to the society at large. Moreover, it orders them to be performed by a sufficient number of Muslim people. The scholars of Islamic law have not found the material element of thegeneral theory of crime that preconditions to inflict punishment on the crimesof manslaughter and actual bodily harm adequate, yet they have also paidattention to whether there are other grounds of justification. One of the factors that removes the criminal responsibility of actual bodily harm when there is no use of violence against rival in sporting activities has been adopted legally by Islamic law, is called “the use of right”. However, the factor that removes this kind of responsibility in the combat sports, which is performed on the rival’s body, is due to a permission taken by the approval of the persons.

    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.

    First Report of a Trilobite in the Carboniferous of Eastern Pontides, NE Turkey

    Kandemir, Raif; Lerosey-Aubril, Rudy

    The pre-Mesozoic basement of the Eastern Pontides consists of a Permo-Carboniferous sedimentary sequence including the Catalcesme and Hardisi formations. The Catalcesme Formation has yielded rich assemblages of fusulinids, corals, gastropods, brachiopods, bryozoans, algae, conodonts and plants. Hitherto trilobites were unknown from this formation; here we report the discovery of a pygidium from a dark grey limestone bed near the top. Trilobites are a minor component of benthic marine communities during the Late Pennsylvanian, and to our knowledge, the discovery of this pygidium constitutes the first report of their occurrence in deposits of this age in Turkey. The morphological characteristics of the specimen, especially the number of axial rings and pleural ribs and the well-defined border (Owens 1983), suggest that it probably belongs to an undescribed species of Ditomopyge Newell, 1931 (Ditomopyginae). It also exhibits a distortion of the posterior part of the axis, and a shortening (right side) or a fusion (left side) of some pleural ribs, which is tentatively interpreted as repaired injuries or the results of a developmental dysfunction.

    The Creative Destruction of Economic Development: The Schumpeterian Entrepreneuer

    Basilgan, Muslum

    The subject of the entrepreneur in economic theory has mostly been examined in terms of development. Schumpeter, who argued that the neoclassical economic theory could not explain the powers of the economic change due to its static base, took a different position by arguing the necessity of a dynamic theory. Schumpeter identified the entrepreneur as essential element of the dynamic theory of economic change. To Schumpeter, the major role of the entrepreneur is to realize new combinations or innovations that ensure economic change. The primary objective of this study is to explore the individual (psychological) and leadership (sociological) characteristics of the Schumpeterian entrepreneur, who leads to creative destruction via the new combinations in the capitalist system: to put forth his difference from other economic actors and to demonstrate his role in the future (the collapse) of capitalism.

    Solution of nonlinear oscillators with fractional nonlinearities by using the modified differential transformation method

    Merdan, Mehmet; Gökdoǧan, Ahmet

    In this paper, an aproximate analytical method called the differential transform method (DTM) is used as a tool to give approximate solutions of nonlinear oscillators with fractional nonlinearites. The differential transformation method is described in a nuthsell. DTM can simply be applied to linear or nonlinear problems and reduces the required computational effort. The proposed scheme is based on the differential transform method (DTM), Laplace transform and Padé approximants. The results to get the differential transformation method (DTM) are applied Padé approximants. The reliability of this method is investigated by comparison with the classical fourth-order Runge-Kutta (RK4) method and Cos-AT and Sine-AT method. Our the presented method showed results to analytical solutions of nonlinear ordinary differential equation. Some plots are gived to shows solutions of nonlinear oscillators with fractional nonlinearites for illustrating the accurately and simplicity of the methods.

    The effects of some organic and chemical fertilizer applications on yield, morphology, quality and mineral content of common vetch (Vicia sativa L.)

    Yolcu, Halil

    A field experiment was conducted to evaluate the effects of some organic and chemical fertilizers on morphological, yield and quality properties and mineral contents of common vetch (Vicia sativa L.) between 2007 and 2008 in Gümüşhane, Turkey. Treatments were control (no fertilizer), liquid manure (LM = 51-52 L ha -1N), chemical fertilizer (CF = 30 kg N ha -1+ 80-100 kg P 2O 5ha -1), three leonardite doses (L 1= 2.8; L 2= 5.6 and L 3= 8.4 kg N ha -1), three zeolite doses (Z 1= 0.4; Z 2= 0.8 and Z 3= 1.2 N kg ha -1) and three solid cattle manure doses (SM 1= 34-35 kg N ha -1, SM 2= 68-70 kg N ha -1, SM 3= 102-105 kg N ha -1). Dry hay yield (DHY), leaf weight, stem weight, plant height, leaf number, crude protein content (CP), crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), Ca, Fe, K, Mg, B, Cu, Mn, Na, Ni, P, Pb, S and Zn contents were determined. Organic and chemical fertilizer applications had significant effect (P<0.01) on DHY, leaf weight, stem weight, CP, CPY and mineral contents except leaf number, ADF and NDF in the both years. The plant height were significantly (P<0.05) affected by the treatments in the first year. The SM 2application in the first year and control and LM applications in the second year resulted to obtain improved yield components and crude protein yield. Z 2and Z 3applications also loomed large in terms of mineral contents.

    The effect of fin pitch on heat transfer and fluid flow characteristics in the entrance region of a finned concentric passage

    Kuvvet, Kemal; Yavuz, Tahir

    In this study, the heat transfer and fluid flow characteristics in the unfinned and internally finned concentric passage (smooth and finned annulus) are investigated experimentally. The turbulence characteristics, mean flow, pressure drop and heat-transfer parameters in the entrance region of a concentric passage of diameter ratio 0.2 are measured. The hot-wire anemometer and the liquid-crystal technique are used for the turbulence and mean flow and the heat transfer measurements, respectively. The finned passage is designed as the fin width (W) of 2 mm, the fin height (H) of 2, 4, 6 and 8 mm and the fin pitch (P) of 20, 30 and 40 mm. Reynolds number ranges from 1.8 .104 to 1.24.105 and from 1.65.104 to 7.65.104 for flow and pressure drop and heat transfer measurements, respectively. Experiments are performed for the smooth and finned concentric passages by varying flow and fin parameters and the effects of the fin pitch are investigated. The developing of fluid flow is analyzed and the variation of turbulence intensity, friction factors, local and mean convective heat transfer coefficients in the smooth and finned concentric passages are obtained. Results obtained in the finned concentric passages are compared with the results of the smooth passage. For the average Nusselt numbers and friction factor, empirical equations are developed. As a result, it is seen that the friction factor in the finned passage increases between 3.61 and 18.05 times while the average Nusselt number augments between 1.36 and 5.23 times on the inner surface and between 1.03 and 1.80 times on the outer surface.
