Arslan, İlyas
Avrupa Dillerinde Genitive olarak bilinen, Ortadoğuda konuşulan Turki, İrani ve Sami dillerinde kullanılan Ezafe kavramı iki sentaktik öğeyi birbirine bağlamak için kullanılır. Genellikle öğelerden biri tamlayan biri ise tamlanan olur. En az iki birimden oluşan bu sentaktik yapıları birbirine bağlayan gramer öğeleri mevcuttur. Dilden dile farklılık gösteren bu öğelerin irani dillerdeki tarihi gelişimleri aynı seyri izlememiştir. Zazaca gibi Kuzeybatı irani diller grubunda tasnif edilen diller tamlama konusunda ayrışırken güneybatı irani diller grubuna ait dillerde Zazaca ile benzeşenler vardır. Bu makalenin amacı Zaza Dilinde var olan tamlama yapısını incelemektir. Gerek isim gerekse sıfat tamlamaları detaylı olarak analiz edilerek bunların dışındaki tamlama şekillerine de göz atılacaktır. Bu sentaktik yapının semantic işlevlerinin olup olmadığı da incelenecektir. Ezafenin tarihi eski irani dillere kadar götürülerek yeni irani dillerdeki yapılarına da bakılacaktır. Zaza Dili ile diğer irani dillerdeki işleyiş karşılaştırılarak benzerlikler ve farklılıklar ele alınacaktır. Ayrıca birçok Zaza ağızlarından tamlama verileri de incelenerek kullanım farklılıklarının olup olmadığı araştırılacaktır.

Yilmaz, Ersen
The blending effect of poly maleic anhydride-styrene-methyl methacrylate (MA-St-MMA) terpolymer on nonmiscible PVC and Polystyrene was studied depending on their thermomechanical properties. Depending on the amount of the synthesized and used compatibilizer the tensile strength, modulus, and thermomechanical properties of the blends are enhanced. The unmodified and blends with small amounts of compatibilizer exhibit two-step degradation whereas those containing 6, 8 and 10 percent compatibilizer showed a single glass transition (Tg). All the results reveal that PS/PVC mixtures modified with MA-St-MMA have superior mechanical properties and phase adhesions than mixtures without terpolymer.

Kismet, Yilmaz; Doğan, Akar
The present study investigates the mechanical and thermal behavior of polyurethane electrostatic powder coating waste reinforced epoxy composites. Different percentages of electrostatic powder coating waste (3, 6, and 9 wt. %) reinforced epoxy composites were manufactured. The mixture of polyurethane powder coating waste and epoxy was mixed with a magnetic stirrer to ensure that the polyurethane powder coating waste was dispersed well in the epoxy, and then the mixture was placed under vacuum and air bubbles were removed. Tensile and three-point tests were performed to determine the changes in the mechanical properties of the materials, and thermogravimetric analysis was conducted to determine the thermal properties. In addition, images were taken with scanning electron microscopy for morphological features. The study revealed that the three-point flexural strength was increased by up to 8% and 15%, respectively, in the samples with 3 wt% and 6 wt% powder coating waste additives. The material's tensile strength decreased by up to 27% with powder coating waste reinforcement. However, the opposite trend was observed in the modulus of elasticity. Additionally, no significant difference was observed in the thermal properties of the materials. Also, from scanning electron microscopy analysis, it was observed that the inclusion of powder coating waste changed the damage mechanism of the material.

The green synthesis of gold nanoparticles (Au-NPs) was carried out by pouring the aqueous extract of East Anatolian origin Asphodelus aestivus plant onto aqueous gold metal ions and reducing them via single-step one- pot method. The absorption peak of the synthesized nanoparticles gave a maximum at 575 nm. All the X-ray diffraction peaks at 2θ = 38.25 , 44.46 , 64.64 and 77.20 that index to (111), (200), (220), and (311) planes verify the successful synthesis of Au-NPs. Mostly spherical shape particles showed a homogeneous distribution with size range 20±5 nm are measured using TEM. From the FTIR spectrum, the peaks are seems to be related to phenolic compounds, flavonoids, benzophenones, terpenoids and anthocyanins which assume that they could act as the reducing agents. The plant extraction, one-pot, single-step method used is environmentally safe without the role of synthetic materials which is highly potential in mild and green synthesis applications. The Au-NPs were coated with chitosan biopolymer in aquatic solution medium and verified by SEM. Then, cytotoxic investigations of the biosynthesized Au-NPs were carried out by HUVEC cells. Au-NPs were showed toxic effects on cell culture, even if in a small amount. However, chitosan biopolymer coating increased cell viability.

Although states take various measures to prevent air pollution, air pollutants continue to exist as an important problem in the world. One air pollutant that seriously affects human health is called PM2.5 (particles smaller than 2.5 micrometers in diameter). These particles pose a serious threat to human health. For example, it can penetrate deep into the lung, irritate and erode the alveolar wall and consequently impair lung function. From this, the event PM2.5 prediction is very important. In this study, PM2.5 prediction was made using 12 models, namely, Decision Tree (DT), Extra Tree (ET), k-Nearest Neighbourhood (k-NN), Linear Regression (LR), Random Forest (RF), Support Vector Machine (SVM), Extreme Gradient Boosting (XGBoost), Multi-Layer Perceptron (MLP), Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), Gated Recurrent Unit (GRU), and Long Short-Term Memory (LSTM) models. The LSTM model developed according to the results obtained achieved the best result in terms of MSE, RMSE, MAE, and R2 metrics.

Polat, Erkan
In composite plate shear walls–concrete filled (C-PSW/CF), there is an indeterminate flow of force between concrete, steel plate and tie bars. Finite element methods (FEM) are frequently used to verify this force flow. The theoretical models available in the literature to predict the tie bar maximum axial force demands were based on walls without boundary plates. The finding in this study is intended to help understand whether current theoretical approaches are conservative and can be applied to boundary plate walls as well. Within the scope of this study, tie bar axial force de-mands for walls with boundary plates consisting of planar and round shapes and without boundary plates were investigated and compared. For this, a previously benchmarked finite element (FE) wall model was considered and configured to have no boundary plate and have planar and round boundary plates. FE models were ana-lyzed under monotonic lateral displacement up to 4% drift ratio. Passive lateral pres-sures and transverse force variations on the planar and round boundary plates were investigated.

Purple basil is widely used medicinally and aromatically due to its essential oil properties, and it is a plant that stands out with its antibacterial, antimutagenic and antioxidant properties. It has been determined that purple basil has positive effects on health such as appetizing, insomnia, sputum, diuretical and antispasmodic. Purple basil contains high concentrations of anthocyanins and with these properties it stands out as a potential new source of stable red pigments for the food industry. In recent years, it has been seen that purple basil has been processed into different products such as tea and sherbet in order to benefit from its functional properties. With the processing of purple basil into different products, it is seen that the consumption of basil and basil products has increased by consumers. In this study, purple basil sherbet samples were concentrated at different voltage gradient values (14, 17 and 20 V/cm) under atmospheric conditions with ohmic heating up to 25% soluble solid content (SSC) and the changes in their rheological properties during the concentration process was investigated. The changes in the rheological properties of the purple basil samples were determined in the range of 1-148 s-1 shear rate values and measurement temperature was 25°C. The compatibility of different rheological models (Newton, Power-Law and Herschel-Bulkley) to the experimental data was statistically evaluated to determine the flow behavior index of the purple basil sherbet samples. It has been determined that the shear stress values increased as the shear rate values increased in all the process conditions. Similarly, at the same shear rate values, it was determined that the shear stress values increased as the SSC values increased. It has been determined that the best suitable rheological model was Herschel-Bulkley Model for all purple basil sherbet concentrates. It is thought that the results obtained will provide important data to the food and machinery industry for the installation of pilot and industrial scale ohmic heating systems.
