Aim: Pulmonary embolism (PE) is a life-threatening condition that requires early diagnosis and treatment. There is still a need for precise and non-invasive biomarkers that can be used to diagnose PE. This study aimed to determine the diagnostic value of Cardiotrophin-1 (CT-1) in patients with acute PE and ascertain the relationship between serum CT-1 level and disease prognosis and severity. Materials and Methods: In this prospective study, the serum CT-1 levels of 165 patients with suspected acute PE were measured. The patients were divided into two groups, PE (+) and PE (-), based on their computed tomography angiography results. Their serum CT-1 levels were compared. Results: The CT-1 levels of the PE (+) group (median=4.18 pg/mL, range=3.57-9.55 pg/mL) was non-significantly (p=0.08) different from those of the PE (-) group (median=4.38 pg/mL, range=3.57-51.64 pg/mL). Based on the severity of the condition, there were significant differences (p=0.001) in the CT-1 levels of the patients in the intermediate-low risk group (median=4.19 pg/mL, range=3.62-5.32 pg/mL), intermediate-high risk group (median=4.06 pg/mL, range=3.57-9.31 pg/mL) and high risk group (median=5.01 pg/mL, range=3.89-9.55 pg/mL). Based on the clinical course, the CT-1 levels of the patients in the good clinical course group (median=4.15 pg/mL, range=3.57-9.31 pg/ml) were significantly different (p=0.004) from those in the poor clinical course group (median=4.53 pg/mL, range=3.66-9.55 pg/mL). Conclusion: CT-1 level was not observed to be a precise biomarker for the diagnosis of acute PE. However, our study demonstrated that the serum CT-1 levels can be used as a biomarker for ascertaining the severity and prognosis of patients with PE.

Cicerali, Derya; Arslan, Mehmet; Yazar, Emel Abdioglu; Yücel, Cem; Temizel, Irfan; Park, Sohyun; Schroeder, Paul A.
Eocene vitric tuffs in the Bayburt area (NE Turkey) possess a dacite-rhyodacite composition and contain abundant altered glass shards and flattened fibrous pumice with lesser amounts of pyrogenic minerals (plagioclase, quartz, biotite, and sanidine). Zeolitization is common and generally develops in the glassy components. The main zeolite mineral found in the tuffs is clinoptilolite, with lesser amounts of analcime and mordenite (?). Smectite is the dominant clay mineral, with lesser amounts of kaolinite also present. Opal-CT, calcite, and dolomite occur as secondary minerals. Scanning electron microscopy studies reveal the dissolution of glass, with the development of popcorn-textured smectites and tabular clinoptilolites developed. The opal-CT spheres found on the clinoptilolite crystals appear to have crystallized simultaneously and are due to excess silica in the environment. Fibrous mordenite (?) also developed on the clinoptilolites. In the clinoptilolites R-r = 0.81-0.82, Si/Al = 4.20-4.70, and K+ is the dominant exchangeable cation (0.65-3.30) seen, together with lesser amount of Ca2+ (0.39-2.25) and Na+ (0.02-2.16). The degree of zeolitization increases with the content of glassy component in the tuffs. The formation of K-clinoptilolite is controlled by the SiO2/Al2O3 (4.9-7.0) and K2O/Na2O (0.8-10.8) ratios in the zeolitized tuffs. delta O-18(V-SMOW) and delta DV-SMOW values of clinoptilolite-rich tuffs range from 22 to 25.6960 and from -96 to -111 parts per thousand, respectively, which suggests that zeolitization occurred at low temperatures (30-55 degrees C) via fluid-rock interactions. Smectite was initially formed from the devitrification of glassy components and is associated with the increase in (Na+ +K+ +Ca2+)/H+ activity and the presence of high pH similar to-9-10) fluids. The zeolites subsequently developed within a saline-alkali shallow marine environment.

Various bike sharing systems (BSS) were designed and used in different cities of the world in the past decade. Manybenefits of the BSS have supplied a rapid growth of this transport mode in all around the world. BSS mainly have manybenefits such as traffic (flexible mobility and multimodal transport connections), health (physical activity) and cost (lowtrip cost). Also a planned BSS can serve an easy access to other public transportation system and can be an importantactor of the public transportation system. Especially in many big cities, bike sharing systems becomes an important partof the public transportation and ensure short travel times to users. However, the growing may causes many problemssuch as demand, safety, effectiveness, cost etc. For this purpose many studies have conducted by the planners,researchers and decision makers to find best solutions to mentioned problems. In the scope of this study, the relationamong average temperature, trip length and trip number was examined for a bike sharing system. For this purpose,Capital Bikeshare system (Washington, D.C., Arlington and Alexandria, VA and Montgomery County, MD) is chosenas pilot system to investigate. Study results showed that there is a strong and positive correlation among temperature,trip number and trip length. Additionally, it was obtained that bicycle utilization has a maximum value between 5-10minutes. This results can be caused by the free utilization duration (30 minutes) of the system for the members.

Gül, F.
Memristor-based resistive random access memory (RRAM) devices are very good competitors for next generation non-volatile crossbar memory applications. The sneak paths problem is one of the main constraints in fabricating crossbar memory devices. The one diode-one resistor (1D1R) structure design is effective for suppressing the sneak paths problem. Suitable circuit models are needed to simulate semiconductor structures.Ageneral circuit model for memristor-based one diode-one resistor structures is proposed in this work. The Simulation Program with Integrated Circuit Emphasis (SPICE) environment was used to simulate the designed circuit. Well-known mathematical models such as those of Strukov, Biolek, Joglekar, Prodromakis and Zha were used to simulate the memristor component of the circuit. The current-voltage characteristics were obtained for different mathematical models. All results were compatible with the expected characteristics. The best fit characteristics were acquired using the Zha and Strukov models.

Başoğlu, M. E.
This paper presents an improved strategy to provide better maximum power point tracking (MPPT) performance and increase energy yield during transient state of MPPT process. This strategy is based on the estimation of short circuit current (SCC) of the photovoltaic (PV) system without short circuit. Besides that, this strategy aims to decrease convergence time to maximum power point (MPP) by preventing real short circuit of PV source and eliminating the additional switch requirement. To determine performance of the proposed strategy, simulation studies have been performed in MATLAB/Simulink and this strategy has been compared with fractional SCC (FSCC) technique and perturb and observe (P&O) algorithm. In addition, to make validation experimentally, a low powered single ended primary inductance converter (SEPIC) is realized. Both simulation and experimental results show that proposed strategy performs better transient MPPT performance than FSCC technique and P&O algorithm.

Başoğlu, M. E.
Submodule level maximum power point tracking (MPPT) systems have become popular due to its outstanding performance in partial shading conditions (PSCs) and basic algorithm requirement. MPPT is realized by DC-DC converters. They are power processing units between photovoltaic (PV) module and resistive load. Among DC-DC converter topologies, the flyback is a proper choice since it can either increase or decrease the voltage. Furthermore, power level is small in submodule level (SML) MPPT applications. In this study, analyzes and power circuit design of a flyback converter for continuous conduction mode (CCM) is carried out firstly. Then, the performance of the flyback converter on the SML MPPT system and its superiority over the module level MPPT is shown by using same converter topology and perturb and observe (P&O) algorithm. In order to validate the superior performance of SML MPPT, it is compared with module level MPPT in MATLAB/Simulink environment. Results show that SML MPPT guarantees global MPPT in any PSCs with any kind of basic MPPT algorithm. On the other hand, module level MPPT fails in many PSCs with the same algorithm. According to simulation results, SML MPPT generated more power by 61.2% in average than module level MPPT systems in simulation studies.

Sancak, Kadir
Kamu diplomasisi kavramının literatürde kullanılmaya başlanmasının henüz yarım yüzyıllık bir geçmişi bulunmakla birlikte bu kavramla ifade edilen faaliyetlerin çok daha eski tarihlerden itibaren uygulandığı bilinmektedir. Kamu diplomasisindeki temel amaç başka toplumları etkilemektir. Bu amaç, kendinizin ve sahip olduğunuz değerlerin her türlü meşru kanalla karşı tarafa tanıtılması şeklinde gerçekleştirilmektedir. Bu bağlamda geçmişe bakıldığında, Hoca Ahmed Yesevi’nin faaliyetleri ile kamu diplomasisi uygulamaları arasında bir bağ kurmanın mümkün olduğu görülmektedir. Türk İslam Dünyası’nda oldukça önemli bir şahsiyet olan Hoca Ahmed Yesevi, on binlerce mürit/derviş yetiştirerek onları Türkistan merkezli olarak doğu-batı, kuzey-güney hattında irşat misyonuyla görevlendirmiştir. Ağırlıklı olarak batıya yönelen bu dervişlerin gittikleri yerlerden biri de Balkan toprakları olmuştur. Henüz Balkan coğrafyasının İslam’la şereflenmediği bu dönemde söz konusu dervişler Hoca Ahmed Yesevi öğretisini buralara taşıyarak, bölgenin Türk İslam kültürü ile tanışmasına vesile olmuşlardır. Dervişler bu topraklarda kendilerine tekkeler kurmuş ve yaptıkları köprüler, inşa ettikleri değirmenler ve bunun gibi faaliyetlerle doğrudan halkla iç içe olmuş ve onlara hizmet etmişlerdir. Başta Sarı Saltık olmak üzere bu gelenekten yetişen dervişler örnek davranışları ile burada yaşayan halka model olmuş ve bu topraklarda İslamiyet’in yayılmasında temel bir rol oynamışlardır. Bu çalışmada Yesevi geleneğinden gelen dervişlerin Balkanların İslamlaşması bağlamındaki faaliyetleri kamu diplomasisi kavramı perspektifinden ele alınacaktır. Esasında modern bir kavram olan ancak uygulama örneklerine çok eski zamanlardan beri rastlanan kamu diplomasisi uygulamaları ile dervişlerin faaliyetleri arasındaki benzerliklere ve farklılıklara işaret edilecektir.

The aim of this investigation was to evaluate an overall performance of the elite women football players. In accordance withthis purpose, 11 women football players (age: 21,5 ± 2,58 years; height: 160,8 ± 5,17 cm; weight: 55,8 ± 7,23 kg) who plays inTurkish Women’s 1st Football League participated voluntarily. In order to measure athlete’s aerobic capacity, Yo-Yointermittent recovery test (Yo-Yo IR1) was applied and maximal oxygen uptake (VO2max) values were estimated by usingrunning distances obtained from the test results. The Wingate anaerobic power test (WanT) to measure the athlete's anaerobicproperties, the vertical jump (VJ) and standing long jump (SLJ) tests to determine explosive power, the Illinois agility test tomeasure agility skills, 10 and 30 meters sprint runs to measure sprint performances, hand grip and back-leg strength tests tomeasure strength characteristics were used. In order to obtain power and velocity parameters, loaded-squat jump (SJLoaded) wasapplied with an resistance that equaled to 40% of body weight and bench throw (BT) was applied with an resistance thatequaled to 30% of body weight of the participants by applying an isoinertial device and results of peak power (PP), peakvelocity (PV), mean propulsive power (MPP), and mean propulsive velocity (MPV) during both movements were recorded.Statistical analysis was used in the assessment of the data. According to analysis results, it was achieved that Yo-Yo IR1 runningdistances was as 676,3 ± 156,4 meters, while VO2max values of athletes were estimated as 42,2 ± 1,20 ml/kg-1/min-1. Relative andabsolute anaerobic power values for elite women football players were obtained as 439,7 (± 61,18 W) and 8,04 (± 1,09 W/kg) formaximal anaerobic power, 316,1 (± 34,46 W) and 5,78 (± 0,56 W/kg) for maximal anaerobic capacity, 193,6 (±22,30 W) and 3,55 (±0,61 W/kg) for minimal anaerobic power, respectively. In addition, fatigue index values measured as 55,7 (± 3,75 %).Participant’s right and left hand grip strength values were obtained as 30,6 (± 4,62 kg) and 29,6 (± 4,5 kg), back and leg strengthvalues measured as 90,2 (± 18,7 kg) and 101,8 (± 29,5 kg), respectively. Participant’s 10 and 30 meters sprint duration wereobtained as 1,85 (± 0,12 sec) and 4,96 (± 0,34 sec). SLJ, VJ and agility values were obtained as 178,4 (± 21,1 cm), 35,7 (± 4,60 cm)and 17,6 (±0,67 sec), respectively. Velocity and power values for athletes during BT movement were obtained as 1,21 (± 0,10m/sec) for MPV, 2,04 (± 0,18 m/sec) for PV, 353,6 (± 83,2 W) for MPP and 666,3 (± 152,1 W) for PP. In response to this, velocityand power values for athletes during SJLoaded movement were obtained as 1,21 (±,10 m/sec) for MPV, 2,04 (± ,18 m/sec) for PV,353,6 (± 83,2 W) for MPP and 666,3 (± 152,1 W) for PP. As a result, although there are many studies on physical or physiologicalcharacteristics of elite male footballers, the literature on the overall performance characteristics of women football players arelimited. It is thought that the results obtained are important to fill this lack in the literature and will be the reference source for future research.
