Same context, different political paths: Two Islamic movements in Turkey

Esen Kirdiş 한국외국어대학교 국제지역연구센터 2016 International Area Studies Review Vol.19 No.3

Two Islamic actors in Turkey have transformed the state’s strict control of the religious field (laicism). While the National Outlook Movement, the “mother-movement” of the governing Justice and Development Party, did so through its “participation” in party politics, the Gülen Movement, Turkey’s most powerful Islamic movement that operates hundreds of schools and a major media network, contributed to this transformation through its “non-participation” in party politics as a social movement, providing an alternative to laicist establishments outside of institutional channels. These two movements, by following different political paths, have embodied different opportunities for and challenges to Turkish democratization. To understand their influence in Turkish politics today, this article will adapt a “method of difference” and ask what explains these two Islamic movements’ variation in regards to party politics and what the consequences of this variation are for Turkish politics. Based on qualitative fieldwork in Turkey, this article will argue that both movements have made their decisions about party politics by strategically and differently evaluating the political opportunities/threats of party politics in light of their varying ideological priorities and organizational needs, and that these strategic decisions have transformed the movements themselves and the Turkish regime altering the laicist status quo between them.

Long Chain Dicationic Phase Transfer Catalysts in the Condensation Reactions of Aromatic Aldehydes in Water Under Ultrasonic Effect

Esen, Ilker,Yolacan, Cigdem,Aydogan, Feray Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.8

Long chain dicationic ammonium salts were used successfully as phase transfer catalyst in the condensation reactions of aromatic aldehydes in water under ultrasonic irradiation for the first time. The quaternary salt having longer distance between the cation centers was more effective than the mono- and dicationic ones having short chain.

On singular integral operators involving power nonlinearity

Sevgi Esen Almali,Gumrah Uysal,Vishnu Narayan Mishra,Ozge Ozalp Guller 강원경기수학회 2017 한국수학논문집 Vol.25 No.4

In the current manuscript, we investigate the pointwise convergence of the singular integral operators involving power nonlinearity given in the following form: \begin{equation*} T_{\lambda }(f;x)=\int \limits_{a}^{b}\sum \limits_{m=1}^{n}f^{m}(t)K_{\lambda ,m}(x,t)dt,\text{ }\lambda \in \Lambda ,\text{ }x\in \left( a,b\right) , \end{equation*} where $\Lambda $ is an index set consisting of the non-negative real numbers, and $n\geq 1$ is a finite natural number, at $\mu -$generalized Lebesgue points of integrable function $f$ $\in L_{1}\left( a,b\right) .$ Here, $f^{m}$ denotes $m-th$ power of the function $f$ and $\left( a,b\right)$ stands for arbitrary bounded interval in $ \mathbb{R} $ or $\mathbb{R}$ itself. We also handled the indicated problem under the assumption $f$ $\in L_{1}\left( \mathbb{R}\right) .$

Spontaneous bone regeneration in resected non-continuous mandible due to medication-related osteonecrosis of the jaw

Alparslan Esen,Gokhan Gurses,Sebnem Akkulah 대한구강악안면외과학회 2021 대한구강악안면외과학회지 Vol.47 No.6

Few cases of spontaneous bone regeneration after extensive resection of the jaw bone have been reported, but it is more common in young adults or children. In this case, we report spontaneous bone healing in a 73-year-old female patient. On radiological examination, necrotic regions were seen in the right mandible. She was diagnosed with medication-related osteonecrosis of the jaw due to previous bisphosphonate use. After segmental resection, stabilization achieved using a reconstruction plate. The periosteum was preserved during the procedure. Twelve months later, panoramic radiography was taken and bone formation was seen both horizontally and vertically around the plate. If the periosteum is preserved and stabilization is achieved after resection in benign lesions, the bone may regenerate spontaneously regardless of age. Therefore, instead of simultaneous autogenous bone ap-plication, such patients may be followed to determine whether spontaneous bone healing will occur. This should improve patient comfort and reduce surgical cost.

Dynamic vibration response of functionally graded porous nanoplates in thermal and magnetic fields under moving load

Ismail Esen,Mashhour A. Alazwari,Khalid H. Almitani,Mohamed A Eltaher,A. Abdelrahman Techno-Press 2023 Advances in nano research Vol.14 No.5

In the context of nonclassical nonlocal strain gradient elasticity, this article studies the free and forced responses of functionally graded material (FGM) porous nanoplates exposed to thermal and magnetic fields under a moving load. The developed mathematical model includes shear deformation, size-scale, miscorstructure influences in the framework of higher order shear deformation theory (HSDT) and nonlocal strain gradient theory (NSGT), respectively. To explore the porosity effect, the study considers four different porosity models across the thickness: uniform, symmetrical, asymmetric bottom, and asymmetric top distributions. The system of quations of motion of the FGM porous nanoplate, including the effects of thermal load, Lorentz force, due to the magnetic field and moving load, are derived using the Hamilton's principle, and then solved analytically by employing the Navier method. For the free and forced responses of the nanoplate, the effects of nonlocal elasticity, strain gradient elasticity, temperature rise, magnetic field intensity, porosity volume fraction, and porosity distribution are analyzed. It is found that the forced vibrations of FGM porous nanoplates under thermal and live loads can be damped by applying a directed magnetic field.

Dynamic response of FG porous nanobeams subjected thermal and magnetic fields under moving load

Ismail Esen,Mashhour A. Alazwari,Mohamed A Eltaher,Alaa A. Abdelrahman 국제구조공학회 2022 Steel and Composite Structures, An International J Vol.42 No.6

The free and live load-forced vibration behaviour of porous functionally graded (PFG) higher order nanobeams in the thermal and magnetic fields is investigated comprehensively through this work in the framework of nonlocal strain gradient theory (NLSGT). The porosity effects on the dynamic behaviour of FG nanobeams is investigated using four different porosity distribution models. These models are exploited; uniform, symmetrical, condensed upward, and condensed downward distributions. The material characteristics gradation in the thickness direction is estimated using the power-law. The magnetic field effect is incorporated using Maxwell's equations. The third order shear deformation beam theory is adopted to incorporate the shear deformation effect. The Hamilton principle is adopted to derive the coupled thermomagnetic dynamic equations of motion of the whole system and the associated boundary conditions. Navier method is used to derive the analytical solution of the governing equations. The developed methodology is verified and compared with the available results in the literature and good agreement is observed. Parametric studies are conducted to show effects of porosity parameter; porosity distribution, temperature rise, magnetic field intensity, material gradation index, non-classical parameters, and the applied moving load velocity on the vibration behavior of nanobeams. It has been showed that all the analyzed conditions have significant effects on the dynamic behavior of the nanobeams. Additionally, it has been observed that the negative effects of moving load, porosity and thermal load on the nanobeam dynamics can be reduced by the effect of the force induced from the directed magnetic field or can be kept within certain desired design limits by controlling the intensity of the magnetic field.

Yuksel Esen,Alper Kurt 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.4

In this study, the change of the effect of high temperature in concrete by the types of mineral additives was examinedexperimentally. For this purpose, CEM I 42,5 R cement was used together with different minerals such as Barite, Diatomite, Silicafume, F class Fly ash that are added in a substituted manner at the rates of 10%, 20%, 30% and 40% by volume. Dry unit weights,underwater weights and water saturated weights of these concrete samples with mineral additives with 28-day strength werefound. Ultrasonic Pulse Velocity (UPV) measurements of the concrete samples, the water absorption percentages by weight ofwhich were determined, were performed. The samples which were then exposed to high temperatures such as 200, 400, 600 and800°C were left for cooling at room temperature, and then, their compressive strength was measured. While the highest waterabsorption rates were in Diatomite reinforced concrete, the highest compressive strengths were obtained in Silica fume reinforcedconcrete.

Yuksel Esen,Eyyup Orhan 대한토목학회 2016 KSCE JOURNAL OF CIVIL ENGINEERING Vol.20 No.7

The objective of this study was to investigate the effect of superplasticizer and mineral admixture contents on the properties of Self-Consolidating Concrete (SCC). Silica fume was used as a mineral admixture and polycarboxylate based third generation superplasticizer was used as a chemical admixture. In order to determine the optimum admixture dosages; trial mixes were prepared with varying admixture dosages. Nine concrete mixtures with different admixture dosages were prepared from trial mixes. Hardened concrete properties and self-compactability criteria of these series were determined and test results were compared between these SCC mixtures. It was observed that 10S1.3A (10% Silica Fume, 1.3% Superplasticizer) and 10S1.5A (10% Silica Fume, 1.5% Superplasticizer) mixtures show the best performance with regard to fresh and hardened concrete properties.

Huseyin Atasoy,Esen Yildirim 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.7

In this study, electroencephalography signals recorded while participants were doing verbal and quantitative tasks, are classified. A dataset containing 1044 records obtained from 18 participants are used for subject-dependent classifications. Features are derived from phase locking values calculated between all channel pairs. Features are reduced before the classification process by using both analysis of variance and correlation based feature selection methods. Instances in the dataset are classified by using the nearest neighbor algorithm. An average classification accuracy of 92.35% is achieved over 18 participants. It is shown that phase locking value is distinctive especially when it is calculated on delta and gamma frequency bands measured between frontal and occipital regions.
