Listening to Students: Modification of a Reading Program Based on the Sources of Foreign Language Reading Anxiety
Belgin Aydn,?pek Kuru G?nen
Turkish Online Journal of Qualitative Inquiry , 2012,
Abstract: This paper is concerned with the modifications implemented in a second year foreign language (FL) reading program with respect to the problems students experience while reading in FL. This research draws on the sources of FL reading anxiety identified in the first year reading program with a motivation to re-design the second year program to help the students perceive reading positively free from the anxiety. This paper reports on the responses of students to the modifications implemented in the second year reading program. The participants of the study were 50 FL students who were in their second year at a state university in Turkey. All participants had already taken the first year reading course and were enrolled in the second year reading course. It was based on two qualitative research instruments. The first instrument was a semi-structured questionnaire administered to all participants. The second one was a semi-structured interview conducted with half of the participants to obtain more in depth information concerning the modifications that had been introduced. Both instruments revealed that students responded positively to the modifications introduced. The results of the study put forward that obtaining students’ opinions, giving them responsibility and involving them in decision making processes enhance their motivation, confidence and analytical skills while reading in a foreign language.
The Economic and Environmental Impacts of Constructing Hydro Power Plants in Turkey: A Dynamic CGE Analysis (2004-2020)  [PDF]

Natural Resources (NR) , 2010, DOI: 10.4236/nr.2010.12007
Abstract: Since Turkey’s economy and population is rapidly growing, Turkey mostly meets its energy demand from imported fossil sources due to the very limited indigenous oil and natural gas resources. However, Turkey has abundant renewable resources especially, hydro power potential to be used for generation of electricity. But only one-third of this significant economical potential could be used. This usage seems insufficient when compared with that of European countries. In order to analyze the potential long term impacts of the hydro power expanding shock on some macroeconomic variables of interest such as GDP, real consumption, real investment, exports, imports, trade balance, and carbon emissions, we developed TurGEM-D, a dynamic multisectoral general equilibrium model of the Turkish economy. Using TurGEM-D, we analyzed the impact of hydro power shock under policy scenario doubling hydro power generation. The simulation results show that doubling hydro power have slightly positive effects on macro indicators and carbon emissions for Turkish economy.

Open Journal of Earthquake Research (OJER) , 2014, DOI: 10.4236/ojer.2014.34014
Abstract: In this paper an approach to estimate near-surface seismodynamic features by using distance- amplitude reduction with geotectonic characteristics of the upper crust in the Eastern Anatolia is discussed. The data set used in this study consists of 287 regional earthquakes in the magnitude range of 3.0 - 6.1, epicentral distances between 15 km and 202 km and their focal depths reaching up to 13 km. The entire study area is divided into three tectonic blocks according to the distribu-tions of the earthquakes and the location of the fault segment. The estimated quality factor QP-S  values for the three regions ranged from 28.6 to 65, highlighting the regional differences in the seismodynamics of the crust. In Eastern Anatolia, the relatively low average quality factor values (QP: 37, QS: 55) show average (0.217) and average values ( \"\"P: 0.0166, \"\"S: 0.017). The lowest Q/QP  value 1.39 and the highest VP /VS  value 1.65 are found at the Mus station. The highest Poisson’s ratio  \"\" and lowest absorption coefficient  \"\" were found in the Mus area. The variation in Q ,  \"\" and  \"\"indicates that the northern part (Erc and Kem region) of East Anatolia appears to be more active and heterogeneous compared with the southern part (Mus region) of East Anatolia.
Long-Run Effects of Customs Union between European Union and Turkey: Is it Zero-Sum Game  [PDF]
Nedret Demirci, Levent Aydn
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.22018
Abstract: Without being a full member of the European Union, Turkey’s participation to the Unity raised some substantial and continued questions in Turkey about the economic results of an regional integration. Some argue that, particularly adoption of the Union’s common external tariff regime would have a devastating effect on Turkey’s trade. The aim of this paper is to search the pros and cons of customs union associated with common external tariff between Turkey and European Union. Our study especially focuses on the effects of common external tariff to Turkey’s trade. The simulation results show that Turkey has been benefiting from the noticeable tariff liberalization as well as improved market conditions in line with EU since it ratified custom union with EU.
Coupling Interactions and Trapped Effects for a Triple-Well Potential  [PDF]
Sezgin Aydn, Mehmet ?im?ek
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.28106
Abstract: Weak and strong coupling interactions and trapped effects have always played a significant role in understanding physical and chemical properties of materials. Triple-well anharmonic potential may be modeled for interpretation of energy spectra from the nuclear to macro molecular systems, and also crystalline systems. Exact periods of a trapped particle in each well of the potential are explicitly derived. For the extended Duffing system, it is predicted that infinite series of both frequency and spatial trajectory approach to exact results in the limit of weak-coupling cases (g→0).

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.62029
Abstract: In this paper, we take Q16 subsemilattice of D and we will calculate the number of right unit, idempotent and regular elements α of BX (Q16) satisfied that V (D, α) = Q16 for a finite set X. Also we will give a formula for calculate idempotent and regular elements of BX (Q) defined by an X-semilattice of unions D.
Current Approach to Treatment of Juvenile Idiopathic Arthritis: Case Report of Hiperimmunglobulin E Syndrome Developed Juvenile Idiopathic Arthritis  [PDF]
Tuba Tülay Koca, Aydn Arslan
Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2015, DOI: 10.4236/ojra.2015.53011
Abstract: Introduction: Juvenile idiopathic arthritis (JIA) represents a heterogeneous group of childhood chronic arthritic conditions. The pathogenesis of JIA remains incompletely understood. This disease can lead to a significant morbidity including joint deformity, growth impairment and a persistence of active arthritis into adulthood. The past two decades have witnessed significant advances in treatment and improved outcomes for affected children. With the current use of biologics, more target-specific, better tolerated, safer and more effective treatments have become possible. However, continuing, comprehensive follow-up is needed to characterize the long-term effects of such treatments. Hyperimmunoglobulin E syndrome (hyper-IgE, or Job’s syndrome) is a rare immune deficiency characterized by high IgE levels, atopic chronic eczema, tendency towards re-current pyogenic infection, neutrophil chemotaxis disorder and varying T-cell function impairment. Case Report: The case of a 17-year-old male patient with hyper-IgE who develops the oligoarticular subtype of JIA over a period of four years is discussed. The course of JIA is unfavorable, causing severe deformity of numerous joints (left elbow, right 3rd metacarpophalangeal, left knee, right ankle) and a fungal infection scar on the left eye. Blood tests show an ESR of 89 mm/h, rheumatoid factor (RF) 8.3 IU/mL (0 - 20) and positive antinuclear antibody (ANA). To improve gait, corrective surgery is performed on the right ankle, followed by rehabilitation and physical therapy. Conclusion: Developments in the near future will be crucial for understanding JIA pathophysiology and improving treatment.
What Type of Defective Feature Do Exceptionally Case-Marked Clauses of Turkish Bear?  [PDF]
Murat ?zgen, ?zgür Aydn
Open Journal of Modern Linguistics (OJML) , 2016, DOI: 10.4236/ojml.2016.64031
Abstract: Core Functional Categories are defined to be v0, T0, C0. They differ in that T0 is not treated as a phase head, while C0 and v0 are assumed to be phase heads: 1) a) [+ phase]: C0, v(*). b) [- phase]: T0. These heads are assumed to bear uninterpretable φ-features. T0 forms a defective a domain unless it is selected by C0. In other words, if T0 is selected by the phase head C0, it starts bearing a full φ-feature set; otherwise, it cannot inherit the features from C0, which leads to a defective domain allowing exceptional case marking (henceforth, ECM). Accordingly, T0 cannot also delete the features of the goal it enters an agree relation. In this respect, the defective features are Case/T0 features in the sense of Pesetsky & Torrego (2007). At this point, some other studies suggest that the defectivity is peculiar to only phase heads, and that T0 is ruled out of this argumentation: 2) a) [+ [+/- defective]]: C0, v0. b) [- [+/- defective]]: T0. There is an asymmetry in the understanding of defectivity between these two reasoning. The aim of this study is to discuss this asymmetry, and present evidence as to which distinction on defectivity does exist. We employed ECM data in Turkish to discuss the relevant distinction with reference to specific empirical proofs such as long distance scrambling, binding and negative polarity items. The results of the study support in favor of Pesetsky & Torrego (2007).

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2005, DOI: 10.4236/jmmce.2005.41001
Abstract: In this study, the ash was sulfurized in an autoclave before flotation. The sulfurization process was conducted at different amounts of H2S and H2O steam. The flotation process was continued with the obtained samples. By flotation of the sample obtained from optimum sulfurization conditions, the concentrates containing all the uranium, molybdenum, vanadium, nickel and titanium was obtained. It was established that the above mentioned elements were enriched 12 times more than the original ash at the concentrate phase. The original ash was tried to enriched by flotation. However, the results obtained from this study was not encouraging. Therefore, ash was sulfurized in autoclave before flotation. In the flotation studies K-isobutylxanthate and Kamylxanthate were used as the collectors and the Aeroflat 65 was used as the frother.
Charcot-Leyden crystals in a prostatic adenocarcinoma

Diagnostic Pathology , 2006, DOI: 10.1186/1746-1596-1-26
Abstract: A transrectal needle biopsy was indicated due to a high level of prostatic spesific antigen in the blood, and a hard right lobe in rectal examination of a 63-year-old man. 10 examples were taken from each lobe of the prostate. In microscopic examination, all examples from the right lobe contained an adenocarcinoma covering 25 to 50% of the biopsies. Only 4 of the examples from the left lobe contained the tumor, which were all small focuses, composed of 8–10 glands. It was one of the biopsies from the left lobe with a small group of neoplastic glands that attracted our attention. Initially, it was the intraluminal bright, eosinophilic crystalloids as a striking low-power appearance. In daily practice, finding crystalloids in a transrectal needle biopsy with a prostatic adenocarcinoma should not be so astonishing. On the contrary, demonstration of intraluminal crystalloids is common in such cases, and even perceived to be an aid in the diagnosis of prostatic adenocarcinoma [1]. The neoplastic group was also incorporated with a dense infiltration of eosinophils. A carefull re-evaluation of other biopsies confirmed that the feature was peculiar to the aforementioned focus. The reaction, which seemed to be almost totally composed of eosinophils, was clearly restricted to the carcinomatous glandular group. Eosinophils were not only surrounding the focus but also looked like 'attacking' the carcinoma cells. Intraepithelial eosinophils forming occasional small groups could easily be found. The interglandular stroma was rich in free granules, an absolute evidence of eosinophil activation. The co-existance of the eosinophils and the crystalloids certainly pointed to a relationship between two. Actually, the crystalloids were extremely similar to the Charcot-Leyden crystals, that we were familiar with in many allergic situations. It was not unlikely, as these crystals were considered to be an other morphologic hallmark of eosinophil activation. When searched, the crystals coul
