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.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114876677","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}

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.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123719839","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}

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.","PeriodicalId":386555,"journal":{"name":"Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675289","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}
