The energy crisis at the point of meeting the increasing energy needs with the fossil-based energy sources that have reached limited reserves today, in parallel with the population growth and the development of the industry, brings the use of clean and environmentally friendly renewable energy sources as an alternative to these sources. Among these sources, the use of solar energy is becoming more and more widespread due to its potential and environmental characteristics. In this study, the design and cost analysis of fixed and mobile energy systems connected to the grid and independent of the grid, in order to meet the electricity need of a villa with a usage area of 250 m2 in Nilüfer district of Bursa province with solar energy. As a result of the study, it has been determined that the fixed system connected to the grid is the most suitable system to be applied to the villa and the cost of the system is $ 9 149. It has been determined that fixed systems have more cost-effectiveness compared to mobile systems, and a fixed system connected to the grid has approximately 67.4% lower cost compared to a fixed system independent of the grid.

Today, with the understanding of the favorable effects of fruit consumption on health, the consumption of pomegranate has increased gradually and solution methods were sought in order to evaluate the peel and seed parts that emerge after the fruit is sorted. In this study, the effects of different drying process (microwave, drying oven, and freeze-drying) and different extraction solvents (ethanol and methanol) on the bioactive components, antioxidant and antidiabetic activities of pomegranate press wastes were investigated. While the highest TPC was in freeze-dried methanolic extracts (5758.70 mg GAE 100 g-1), the highest TFC and MA contents were determined in microwave-dried ethanolic extracts with values of 1068.75 mg QE 100 g-1 dw and 215.44 mg cyn-3-glu 100 g-1, respectively. The highest DPPH antioxidant activity value was determined in freeze-dried ethanolic extracts with a value of 99.14%, and the highest ABTS value was determined in freeze-dried methanolic extracts with a value of 18.20 mmol Trolox g-1. α-amylase and α-glucosidase inhibition values of the samples range from 8.87 to 28.56 mg L-1 and 9.57 to 29.88 mg L-1, respectively. All samples had higher α-glucosidase inhibitory activity compared to acarbose. The results showed that pomegranate press waste, which is thought to have no use in the food industry, is a potential resource that can be used in the pharmacology and cosmetics industries as well as its use as a food supplement, thanks to its high antioxidant and antidiabetic properties.

In microbiological studies starting number of bacteria is essential. The classical plate count method is one of the most reliable methods but it's time-consuming. This study offers a fast method based on turbidity. With this method, a measurement can be directly made using bacteria-free growth media as a blank and bacterial mass in growth medium for broth cultures. This study describes how to form the calculator on Excel.

Data security is very crucial for communication systems. Encryption methods are frequently used to ensure the security. Chaotic oscillators are used for encryption of data because they produce signals that do not repeat themselves. Identical chaotic oscillators should be used and synchronized with each other in order to perform encryption and decryption processes in a healthy way. In this study, the encrypted data and synchronization signal are transmitted to the receiver side using frequency division multiplexing (FDM) method to realize the synchronization between two chaotic oscillators. High-frequency keying is used to increase the encryption quality of the signal to be encrypted on the transmitter side. Proportional-Integral-Derivative (PID) control is used to provide synchronization between two chaotic oscillators. Correlation test, peak signal to noise ratio (PSNR), mean square error (MSE) and spectral entropy were used to determine the accuracy relationship between the original signal and the decryption signal. As a result, the encryption success and reliability of the created system were verified by simulation programs and numerical analysis.

P-type Cu2FeSnS4 (CFTS) quaternary chalcogenide films have been grown by method of spin coating on glass substrates relate to 30 and 40 sccm sulfur flux. Physical properties of obtained samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and ultraviolet visible (Uv-vis) spectrophotometer to see the effect of deposition parameters on the thin film. The crystal parameters including crystal size, dislocation density and strain value of the samples were changed related to the deposition parameters. XRD results indicated an improvement of crystalline quality of quaternary chalcogenide CFTS with a maximum crystal size about 50 nm for (112) peak orientation. SEM images illustrated that the particle size was changed with increasing in the flux of sulfur, which was confirmed with both XRD and AFM images. It was seen that the absorption and energy band gap value of the samples changed the effect of sulfur flux and CFTS film for 40 sccm exhibited more strong absorption than CFTS film for 30 sccm in the Uv-vis region. The band gap values of the samples were calculated as 1.56 and 1.63 eV for 30 and 40 sccm, respectively. The results propose.that samples for 30 sccm flux rate produced at 550 °C have the good physical properties.

In this work, harmonic analysis of current and voltage waveforms, and investigation of efficiency, output power and torque characteristics of a three-phase, squirrel cage induction motor with full-, under-, and over-pitched stator windings under sinusoidal excitation are carried out. Performance analysis have been performed via Ansys/RMxprt software by modelling the stator winding with coil pitches of 100°, 120°, 140°, 160°, 180°, 200°, 220°, 240° and 260°. Current and voltage harmonics analysis have been performed in Matlab using the data obtained from Maxwell/2D simulations. Results showed that both under-pitched and over-pitched coils can be used to eliminate harmonics in the current and voltage waveforms. Under-pitched coils provide higher efficiency than the over-pitched coils. There is no unique coil pitch configuration to eliminate all harmonic components. Therefore, in order to eliminate a specific harmonic component, a specific coil-pitch must be applied.

Let V(RG) denote the normalized unit group of the group ring RG of a group G over a ring R. The concept of G-nilpotent unit in a commutative group ring has been defined in (Danchev 2012). In this study, some necessary and sufficient conditions for a normalized unit group in a commutative group ring of a direct product group G×H to consist only of G×H-nilpotent units have been given and especially some results which are related to groups G×C_3 and G×C_4 have been introduced where C_3 and C_4 are cyclic groups of orders 3 and 4 respectively. In this context, we can say that the paper extends the results in (Danchev,2012). At the end, an open problem is served as a future work.

At the end, an open problem is served as a future work.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115102827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
