First of all, the total energy (ΔETotal), enthalpy (ΔH), and Gibbs free energy (ΔG) values for both tautomeric structures of midaflur were calculated and it was determined which form was more stable and the rest of the study was continued on this structure. For the stable amino form, the HF method and B3LYP/B3PW91 DFT functionals with different basis sets were used in order to examine the geometric parameters. The results were found to be in good agreement with the experimental values given in the literature. Furthermore, FT-IR analysis, Mulliken population analysis, frontier molecular orbital (FMO) analysis, natural bond orbital (NBO) analysis, nonlinear optical (NLO) properties, and electrostatic surface properties were studied in detail. In another part of the study, the logPow (logarithm of the n-octanol/water partition coefficient) value, which is the numerical expression of the lipophilicity of a drug for entry into the CNS, was estimated for midaflur. For this purpose, the calculations were repeated for the water and n-octanol phases using the universal solvation model based on density (SMD) for all the methodologies used in this study, and the free energies of solvation were predicted. It was concluded that the predictive power of the computational methods increased in the order of HF < B3PW91 < B3LYP.","PeriodicalId":325089,"journal":{"name":"Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125803700","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}

As a result of the experiments, it was found that the friction coefficient value increased from the non-reinforced alloy to the 10% SiCp-reinforced composite, while it then decreased in the 15% and 20% SiCp-reinforced composites. Moreover, the amount of wear in the composite material increased as the ratio of the reinforcement increased, and the highest wear occurred in the 10% SiCp-reinforced composite. This wear rate decreased in the 15% reinforced composite and then increased in the 20% reinforced composite. The deformation wear statuses of the composite materials that were used in the experiments were examined by conducting SEM (Scanning Electron Microscopy) and EDS (Energy-Dispersive Spectrometry) analyses. In these examinations, it was observed that the 5% and 10% SiCp reinforcements did not show a homogeneous distribution in the matrix, but the 15% and 20% SiCp reinforcements were homogeneously distributed in the matrix material.","PeriodicalId":325089,"journal":{"name":"Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132649666","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}

New digital circuit based architecture is improved for erasure error structure in a FPGA (Field Programmable Gate Arrays) complier Quartus. The results are investigated in the Modelsim-Altera simulator in terms of the time chart. According to obtained results, it is shown that proposed digital circuit based architecture can successfully correct the error slots. Additionally, the performance of slot error rate has been analyzed for both erasure and false alarm errors of which the theoretical frameworks are obtained. It is shown from results that erasure error correction system (S-DHPIM) has better slot error rate performance than that of traditional DH-PIM (G-DHPIM).

The most important factor in the occurrence of failures is the high pressure in the system and the fluctuation in the pressure. Therefore, it is necessary to control the pressure and reduce the fluctuations in order to reduce the occurrence of new faults. However, pressure control is a costly process that requires extensive fieldwork. Therefore, before applying pressure management, the costs (equipment, field works, and installation) and benefits (potential water volume to be added to the system, potential reductions in failure) should be considered. The aim of this study is to develop a calculation tool to analyse the costs and benefits of applying pressure management in an isolated zone. For this purpose, cost components were defined according to field data. In addition, based on the approaches suggested in the literature, reductions in leakage and failure rates due to pressure control are determined. These fault and cost components are defined in the developed calculation tool. It is thought that this developed calculation tool will be a reference especially for practitioners. In this calculation tool, cost-benefit components are also defined for isolated site studies.","PeriodicalId":325089,"journal":{"name":"Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127446586","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}

Disease, pests, and weeds that result in problems in apple orchards may restrict apple production. Although the direct impact of the weeds on apples is limited, they can be significant, especially at an early stage due to competition for water, nutrients, and light. The most preferable method to prevent crop losses is herbicide use. If the herbicides were used in the same place without a rotation, herbicide resistant populations may become apparent. Implementation of resistance management following herbicide-resistant population covers more long-term and extensive studies. This study was conducted to determine Glyphosate resistance horseweed (Conyza canadensis) population in apple orchards of Isparta from 2015 to 2019. Bioassay techniques were employed to determine the resistance. In the screen test, the recommended rate of glyphosate was applied to the horseweed populations that were grown in the growth chamber and their resistances were determined. In the dose-response experiments, logarithmic rates of glyphosate were applied to horseweed populations and the impact was identified by non-linear regression analysis. I50 values of suspected glyphosate resistant populations were 96.087 and 83.126ml commercial ingredient/da and 106.48 and 98.82ml commercial ingredient/da for F1 and F2 populations, respectively. The populations separated as suspected glyphosate resistant horseweed have been considered as high-level herbicide tolerant.","PeriodicalId":325089,"journal":{"name":"Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133647656","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}

On the other hand, it is also important to detect the instance the activation is triggered. One of the powerful techniques that can analyze the abnormal behavior of any data is change point (CP) analysis. We suggest that CP detection algorithms also can be used to locate the activations in functional magnetic resonance imaging (fMRI) sequences, as well. Our paper presents a two-fold innovative study in that respect. First, we propose to use CP detection algorithms to locate the activations in fMRI signals as a state-of-art topic. Furthermore, we propose and compare a set of change point analysis methods, a regression-based method (RBM), a statistical method (SM), and a mean difference of double sliding windows method (MDSW)) to locate such points. Second, we apply these methods to the fMRI signals, which are acquired from the real subjects, while they were performing fMRI tasks. Proposed methods were applied to three different fMRI experiments with a motor task, a visual task, and a linguistic task. The analysis shows that the methods find activations in accordance with established methods such as statistical parametric maps (SPM). The acquired up to 94 % results also show that the proposed methods can be used effectively to locate the activation times on fMRI time series.","PeriodicalId":325089,"journal":{"name":"Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132953676","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}
