Çaglar, Hakan; Çaglar, Arzu; Can, Omer
In this study, it was aimed to develop properties of cement paste having standard properties and produce a graphene doped Polyvinyl Alcohol (PVA) and boron-based cement paste in this context. This type of special cement is mixed with PVA as polymer additive material so it can have a higher strength and sufficient elasticity per unit weight. Also, boric acid which can absorb neutrons having poisonous effect in nuclear reactions is added into the cement in order to minimize environmental disaster caused by a nuclear accident. Compressive and bending strengths were measured based on TSE tests of graphene doped PVA and boron-based cement paste. Then, samples were measured by Brunauer-Emmett-Teller Method (BET) and subjected to X-ray Diffraction (XRD). In XRD measurements, crystalline structure was observed in all materials. According to compressive strength tests, as the graphene amount increases compressive strength also increases, however in bending strength tests as the graphene amount increases bending strength decreases. Although the values of bending strength of samples produced decreased with increase of graphene content, these values were found to be above the standard values. In addition to boron, graphene admixture has a significant effect on material with its positive strength properties.

Sadigov, Ramin
One of the important fronts that the Ottoman Empire fought during the First World War was undoubtedly the Caucasus front. Compared to the other fronts, the Ottoman and Tsarist Russia were especially concerned about this front because it was the initial point for attacks targeting Central Anatolia. Erzurum became a Russion target after the 1828-1829 Ottoman-Russian War. Also, during the First World War, Russian's main aim in the Caucasus front was to occupy Erzurum. The most important reason why the Russians attacked Erzurum was that Erzurum was the headquarters of the Third Ottoman Army and also was the logistical supply center not only for Eastern Anatolia, but also for the Caucasus and the Iraq region, providing support for Turkish military operations. There are several studies about the occupation of Erzurum. Still, the question of how the Russian press and literature of the period handled the occupation of an important fortress such as Erzurum and the resonation of this occupation in Russia and in the world, have been neglected. This study examines the point of view of the Russian press and literature on the occupation of Erzurum and the reflections of this occupation in Russia and in the world.

Güzel, Ferdi
Derleme Sozlugu is the most comprehensive and the most important work in the field of Turkey Turkish dialects vocabulary. But when it comes to lexicography principles, there are some mistakes in this important study. It is among the important mistakes that some words without real local dialect data are included. In the Derleme Sozlugu, there are two kinds of words that are not actual dialect data, words taken from written sources and derived words. Some compilers sent the words they obtained from written sources and the words they derived from them as compiled words. Since it could not be determined by those who prepared the Derleme Sozlugu, a number of words entered into the Derleme Sozlugu that did not have local dialect data. Some studies have mentioned that there are some words taken from the written sources in the Derleme Sozlugu. The derived / fabricated words will be discussed for the first time in this study. It is a must to reorganize the Derleme Sozlugu which is the most important work in the field of dialect research. The Derleme Sozlugu which is reorganized and enriched with new compiled materials will be a better dictionary in terms of both reliability and usability.

Yilmaz, Yahya Yasin; Yalcinkaya, Esra Evrim; Demirkol, Dilek Odaci; Timur, Suna
Hybrid materials containing organic and inorganic structures are very important because they have the advantages of each of their components. Intercalation of the organic molecule to inorganic structures such as clay allows the preparation of multifunctional new immobilization matrices that contain both the strength properties of the clays and the properties of the organic molecule such as its functional groups (amine, carboxyl or hydroxyl etc.). In this study, 4-aminothiophenol intercalated montmorillonite (4ATP-Mt) was prepared and used as an immobilization layer for the pyranose oxidase (PyOx) enzyme on a glassy carbon (GC) electrode. Firstly, 4ATP intercalation of Mt was carried out, and the success of intercalation was proven using Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffractometer (XRD), and Thermogravimetric Analysis (TGA) techniques. Then PyOx was immobilized using 4ATP-Mt, BSA and glutaraldehyde as a cross-linker on the surface of GC electrodes. To show the coating steps for the preparation of 4ATP-Mt/PyOx biosensors, cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS) techniques were applied, and surface morphology was visualized by scanning electron microscopy (SEM). After optimization of working conditions, analytical performance parameters were determined for glucose detection. The 4ATP-Mt/PyOx biosensor exhibited a wide linear concentration range between 0.01 and 0.5 mM (LOD: 1.0 mu M) for glucose. Additionally, the fabricated 4ATP-Mt/PyOx was assayed for the analysis of glucose in artificial body fluids and drinks.

The goal of this study was to determine some physicochemical and microbiological properties of Erzurum butter. Random samples (n = 30) were collected from different retail markets throughout Erzurum province. The pH, acidity, and melting point values of samples were 3.88, 0.47%, and 30.03 degrees C, respectively. The salt, fat, and moisture values of some samples (sample no 1, 14, and 18) were not harmony with Turkish Food Codex. The highest and lowest peroxide, iodine, saponification, Reichert-Meissl (RM), and Polenske values were found to be in the range of 0-0.51 mEqO2/kg, 22.97-38.64, 195.45-228.54, 17.08-30.-56, and 0.72-1.80, respectively. The refractive index value (RI) was changed from 1.4591 to 1.4620. Total coliforms, aerobic mesophilic bacteria (TAMB), lactic acid bacteria (cultured in MRS and M17), and mould and yeasts mean counts were 1.07 log CFU g-1, 6.79 log CFU g-1, 6.45 log CFU g-1, 6.76 log CFU g-1, and 5.33 log CFU g-1, respectively. There were high differences in physicochemical and microbiological properties of butter might be attributed to a non-standard production process as well as non-standard raw material. In sum, the sanitation and storage conditions should be improved from production to consumption to improve the butter quality.

Purpose This paper aims to investigate the effect of straight phenolic resin content on the fade behavior, frictions and wear characteristics of pre-determined brake pad composite matrix having specific amount of barite (BaSO4), rock wool, Kevlar, graphite and magnetite. Design/methodology/approach Different amount of resin ranging between 16 and 20 wt. per cent were added by changing only the filler (barite) content of composite matrix. Subsequently, friction and wear behavior of the composite samples were analyzed using a special pin-on-disc type test system developed for brake pad sample. The worn surfaces were investigated by SEM and three-dimensional (3D) surface profilometer. Findings The average coefficient of friction (CoF) of composite samples and temperature of the disc surface showed a linear increase with decreasing the resin content. The sample having 20 wt. per cent resin showed the minimum wear rate with smooth worn surface. But the amount of fade is quite high in that sample. Decreasing resin content decreased the fade formation, and the composite with 16 per cent resin brought about the minimum fade formation. As the fade formation is unwanted in brake pad applications, the composite with 16 wt. per cent resin was proposed as the most appropriate one considering the performance parameters related to friction and wear. Originality/value This paper optimizes the resin content of composite brake pad materials to achieve the best combination of its tribo-performance and mechanical properties and provides valuable information for scientists and engineers working in that area.

An exopolysaccharide (EPS) producer slimy-mucoid type colony was isolated from sourdough and identified as Weissella cibaria MED17. The 1H and 13C NMR spectra of EPS MED17 demonstrated that this EPS was a dextran type glucan ((1 → 6)-linked α-D-glucose core structure) containing (1 → 3)-linked α-D-glucose branches and proportion of (1 → 6)-linked α-D-glucose units to (1 → 3)-linked α-D-glucose units was 94.3:5.7%. The FTIR analysis also confirmed the (1 → 6)-linked α-D-glucose linkage. A high level of thermal stability was observed for glucan MED17 as no degradation up to 300 °C was observed by TGA and DSC analysis. The XRD analysis of glucan MED17 showed its semi- crystalline nature and its compact sheet-like morphology was observed by SEM analysis. Finally, antioxidant characteristics of glucan MED17 were determined by ABTS and DPPH radical scavenging activity tests that revealed a moderate antioxidant activity of glucan MED17. These findings show potential techno-functional characteristics of glucan MED17.

Salik, M.A.; Arslaner, A.
Ten types of classic and probiotic (Saccharomyces boulardii) ice cream were produced using different mixture combinations containing 10 or 20% Saruc, a traditional Turkish snack containing dried Cimin grape, Kemah walnut, and 0.5 or 1.0% grape seed. Physical, chemical, and microbiological analyses conducted during the storage period (days 1, 15, 30 and 60 at-20 ± 1°C) were used to assess the probiotic shelf life and quality properties of the ice cream samples. The desired therapeutic effects of S. boulardii levels in probiotic products were from 106 to 108 CFU/g during storage. The results revealed that Saruc, grape seed, and S. boulardii had a significant effect on the quality properties of ice cream samples. Titration acidity, total dry matter, fat, protein, ash, glucose, fructose, total sugar, viscosity, first dripping time, complete melting time, a& value, and calorie (kcal) values increased with increasing concentration of Saruc. However, pH, sucrose, melting rate, L&, and b& values decreased. Grape seed increased titration acidity, protein, fat, ash, viscosity, first dripping time, complete melting time, and calorie values in all samples, but decreased the pH values. The addition of Saruc and grape seed positively affected the growth and viability of S. boulardii at levels from 106 to 108 CFU/g during storage. Taking all the quality parameters into consideration, it was shown that with the addition of Saruc, grape seed, and S. boulardii, new functional ice creams with high nutritional value could be produced.

Azerbaijan is an important region for the beekeeping and honey industry. Biochemical characteristics of eleven honey samples from different regions of Azerbaijan were analyzed through measuring electrical conductivity, optical activity, moisture content, proline and diastase number. Phenolic components are analyzed by reverse-phase high-performance liquid chromatography (RP-HPLC) with UV–Vis double beam detector. Sugars profiles of samples were carried out using HPLC with a refractive index detector (RID). Total phenolic content (TPC), ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picryhydrazyl (DPPH) free radical scavenging activity were measured with the aim of gathering information on the antioxidant power of samples. Biochemical and antioxidant characteristics are also supported with melissopalynological data. Conductivity ranged between 0.32 and 0.82 mS cm−1, moisture 14.52 and 20.78%, proline 314.34 and 1077.21 mg kg−1, diastase 13.05 and 22.19. Azerbaijan honeys exhibited levorotatory properties. Total phenolic content varied from 18.82 to 154.75 mg gallic acid equivalent per 100 g honey. The results confirm that physico-chemical and biologically active properties of Azerbaijan honeys are affected by the flora and geographical variations.

Serancam, Ugur; Dabanli, Ismail
Surface temperature increase due to global warming results in polar ice melting, snow cover thinning, changes in precipitation anomaly. All these phenological effects alert engineers, planners and administrators to be more sensitive against climate change-based risk effects on water structures. Vulnerability to natural disasters such as floods and droughts are expected to occur more frequent than past. Therefore, design and potential evaluation of water structures such as transmission channels, water wells, dams and hydraulic power generation facilities need to be re-evaluation. This re-evaluations procedure must be updated by taking into consideration climate change impacts with their risk assessments. For this purpose, the climate change-based risk levels are calculated from historically available records through possible trend tendencies, which are expressed in terms of trend slope. It has been observed that, in general, the climate change impacts are not significant on precipitation and runoff. This is due to the low trend slopes in the standardized hydro-meteorological time series. This point has been documented for Yesilirmak basin, where the climate change impact is very limited.

Arİ, Yılmaz Onur; Bello, Ibrahim
The paper examines the impacts of remittances on terrorism for Turkish economy by using annual time series data covering the period of 1990-2019. Autoregressive Distributed Lag (ARDL) was used in the application of econometric method. To ensure robustness of results, the study accounts for structural breaks in the unit root test and the co-integration analysis. The results obtained indicated that remittances flows to Turkey have a positive and significant effect on terrorism. This is in line with the empirical evidence that finances through remittances can promote terrorism in a country. The study also concludes that unemployment has strong a correlation in promoting terrorism in Turkish economy and that persistent unemployment can cause economic inequality, poverty, social dislocation, unrest, and conflict such as terrorism, which has a negative impact on subsequent long-run economic growth. Besides, trade openness shows a negative but significant effect, which indicates that trade openness has a little influence in promoting terrorism.

This study investigated the effects of an essential oil mixture (EOM; Eucalyptus globulus labill, Tymus vulgaris, Cymbopogon nardus, and Syzgium aromaticum) added to drinking water on temperature-stressed broilers. The performance parameters (body weight, average daily weight, feed intake, and feed conversion ratio), meat quality, and thiobarbituric acid-reactive substances (TBARS) were evaluated. In a 42-d study, 400 Ross-308 male chickens (1-d-old) were randomly assigned to 8 different groups (n = 50), each containing 4 subgroups (n = 8) (22°C Control (C), C + 250 mL/1,000 L, C + 500 mL/1,000 L, C + 750 mL/1,000 L), 36°C (stress control (SC), SC + 250 mL/1,000 L, SC + 500 mL/1,000 L, SC + 750 mL/1,000 L). Adding 750 mL/1,000 L at 22°C and 250 mL/1,000 L at 36°C was more beneficial to the fattening performance parameters than those in the control group. EOM reduced liver weight but increased abdominal fat in the SEOM-250 groups but did not affect other organ weights. EOM had no effect on the TBARS or the b* color parameter while it augmented the a* and L* coordinates of meat color.

In this study, the probiotic properties of 80 lactic acid bacteria (LAB) strains isolated from pastırma, a dry-cured meat product, were investigated. For this purpose, strains were investigated for their resistance to bile salt and hydrophobicity abilities. In 6 strains selected as a result of these analyses, development at high salt concentrations, auto-aggregation and co-aggregation, resistance to low pH, and adhesion analyses were performed. The growth percentage of all strains decreased with increasing bile salt concentration at both 25 °C and 37 °C. P. pentosaceus K7, K41, K44, K51 and K81 and P. acidilactici K99 gave the highest values in terms of hydrophobicity ability. The highest auto-aggregation and the highest co-aggregation were found in P. pentosaceus K41 (17.62%) and P. pentosaceus K44 strain (26.23%), respectively. These six strains showed tolerance to high acidity even at pH 2. The strains significantly maintained their viability in the simulated gastric and intestinal fluids. Furthermore, the strains had low adhesion capacity in Caco-2 and HT-29 cell lines and generally showed resistance under gastrointestinal system conditions. As a result, P. pentosaceus K44, P. acidilactici K99 and P. pentosaceus K41 could be considered as probiotic strains.

Karakus, Murat; Guler, Evrim
A Software-Defined Networking (SDN) architecture and OpenFlow can help network administrators to provide end-to-end (E2E) Quality of Service (QoS)-guaranteed paths for flows among networks while providing finer-granular flow management along with global network view. In this context, we introduce a proof-of-concept for a blockchain-enabled QoS-based inter-Autonomous System (AS) routing framework, RoutingChain, that blends a QoS-concerned routing model and blockchain technology. This study's contributions can mainly be stated in five-fold: (i) Competitors-tailored routing coordination framework, (ii) eliminating centralized mediators while coordinating QoS-based inter-AS routing, (iii) an emerging use-case for blockchain technology in networking, (iv) reducing the number of QoS signaling-based message overhead, and (v) mitigating privacy/security concerns in inter-AS routing. Experimental results indicate that the blockchain technology can be applied on E2E QoS-based routing among networks. To the best of our knowledge, this is the first study exploiting the merits of blockchain technology to establish a novel coordination framework for QoS-enabled inter-AS routing in SDN.
