In recent years, the signal role of GABA in the stress response has of special interest. However, the effects of exogenous GABA on phenolic compounds which have special roles as antioxidants are not well known. In this study, the effects of exogenous GABA on endogenous GABA and phenolic contents were analyzed in tomato plants under salt stress. Tomato plants were grown in a growth chamber under controlled conditions and NaCl and GABA were applied in Hoagland solution. Qualitative and quantitative analysis of GABA and phenolic compounds (Benzoic, caffeic, chlorogenic, gallic, hydroxybenzoic, syringic, rosmarinic, p-coumaric, sinapic, t-cinnamic, t-ferulic acids, catechin, epicatechin, hesperidin and quercetin) were measured by HPLC. Differences were found in chlorogenic acid, coumaric acid and gallic acid among the phenolic substances. We found a significant increase in gallic acid and coumaric acid contents under 200 mM NaCl and GABA applications. Exogenous GABA treatment caused a slight increase in endogenous GABA content. The increase in GABA content under GABA+salt treatments were higher than that of single salt and GABA applications. According to our results we can suggest that exogenous GABA could enhance the stress response by enhancing some phenolic substances and GABA content under salt stress.","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"16 1","pages":"61-64"},"PeriodicalIF":0.0,"publicationDate":"2018-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89606121","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}

To achieve this, many painting robots are attached with expensive color sensors. However, these sensors are coming with many drawbacks such as color ranges limitation and sensitivity to illumination in addition to their high costs. In the last decades, camera systems gained importance in robotics applications with the power presented by the computer vision techniques. The main objective of this paper is to design an automation line that includes a robot and camera system to perform painting in different colors, with various illumination conditions at cheaper costs. The proposed system can be used to paint multiple colors effectively and accurately. The power of the system comes from the color detection and classification algorithm that is designed using computer vision techniques. The algorithm is designed under C++ environment using OpenCV library. The system will able to detect all colors that are adjusted/predefined offline by the user and to work in different illumination conditions. The end-effector of the robot consists of two main parts, a camera to detect the desired color and an automatic spray gun to perform the painting operation. The proposed system detects will do so based on a small sticker pasted on the object that will be painted. When the desired color is detected, the system starts the painting operation. Moreover, the system has the capability to automatically cleaning the spray gun and the connected tubes in the case of having the successive objects to be painted in different colors.","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"15 1","pages":"17-22"},"PeriodicalIF":0.0,"publicationDate":"2018-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74623883","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}

The ecological importance of earthworms on terrestrial ecosystem is mainly attributed to their close synergistic interaction with soil biota. Among earthworms, Eisenia fetida has been considered as preferred for vermiculture and vermicomposting practices due to their reproductive potentials, short life cycle and wide temperature and density pressure tolerances. Although the genome and transcriptome data for E. fetida are available, the EST-SSRs composition and frequency of this species, which used for phylogenetic studies, genus-level taxonomy and population genetics, remain poorly defined. In current study, we mined publicly available transcriptome data and characterised genome-wide EST-SSR markers for this epigeic species. A total of 13,060 EST-SSRs were identified from 162,609 contigs. The most abundant EST-SSR types were found to be trimeric repeats (5,998, 46%) followed by dimeric (4,762, 36%), tetrameric (1,716, 13%), pentameric (478, 4%) and hexameric repeats (106, 1%). For SSR motifs, the most prevalent motifs were AC/GT (14.72%), followed by AT/AT (13.20%), ATC/ATG (13.03%), AAT/ATT (12.30%) and AG/CT (8.46%). Following validation of the species using COI sequences and to test the designed primer pairs, the eight primer pairs were designed, but only six of them were successfully amplified. Although EST-SSR information is scarce for annelids, the EST-SSR patterns of E. fetida seem to be similar to annelids. Overall, the EST-SSR markers help in taxonomic resolution of Eisenia genus from other earthworm genera and in studying the population structure and geographic distributions of E. fetida .","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"1 1","pages":"135-140"},"PeriodicalIF":0.0,"publicationDate":"2018-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88206029","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}

There are some cell viability methods based on fluorescence or non-fluorescence detection. More simplified evaluation for cell viability, such as trypan blue staining, can be preferred before performing fluorescence assays. This appears advantageous when to have a large number of cell samples in ELISA plates after treatments with different concentrations of drug candidates. Thus, further fluorescence assays can include less concentrations rather than experiencing all used along 96-well plates. For this, trypan blue exclusion method is an option. Traditionally, treated cells are harvested by centrifugation and incubated with trypan blue within tubes followed by transferring the mixture into a hemacytometer with two chambers and assessed under the microscope. Nevertheless, using a hemacytometer limits practicability of this method when analyzing various cell samples into 96-well plates at the same time. This study was aimed to adapt trypan blue method to in situ staining of adherent cells cultured on ELISA plates. For this, cells were fixed with different fixatives after trypan blue incubation to maintain cells in impenetrable meshwork, and paraformaldehyde was the most effective fixative. This modified protocol was validated by testing the effect of dimethylsulfoxide-a cytotoxic agent-on cells, and expectedly found that cell viability reduced with higher concentrations of dimethylsulfoxide suggesting that in situ detection of cell viability by trypan blue can be a useful tool for preliminary detection of cells cultured on ELISA plates before performing automatized experiments with such flow cytometer and/or microplate reader.","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"14 1","pages":"99-104"},"PeriodicalIF":0.0,"publicationDate":"2018-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75026657","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}

They are classified as numeric, group and polynomial invariants. These invariants contribute to the problem of classification of knots. In this study, we have done a study on the polynomial invariants of the knots. First of all, for (2,n)-torus knots which is a special class of knots, we calculated their the Kauffman bracket polynomials. We have found a general formula for these calculations. Then the Tutte polynomials of signed graphs of (2,n)-torus knots, marked with a {+} or {-} sign each on edge, have been computed. Some results have been obtained at the end of these calculations. While these researches have been studied, figures and regular diagrams of knots have been applied so much. During the first calculation, we have used skein diagrams and relations of the Kauffman polynomial. In the second calculation, the Tutte polynomials of (2,n)-torus knots have been computed and at the end of the operation some general formulas have been introduced. The signed graphs of (2,n)-torus knots have been obtained by using their regular diagrams. Then the Tutte polynomials of these graphs have been computed as a diagrammatic by recursive formulas that can be defined by deletion-contraction operations. Finally, it has been obtained that there is a relation between the Tutte polynomials and the Kauffman bracket polynomials of (2,n)-torus knots.","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"364 1","pages":"929-932"},"PeriodicalIF":0.0,"publicationDate":"2017-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73423441","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}

In recent years, interest in electric vehicles has begun to increase, especially due to the environmental problems. In the near future, it is estimated that gasoline and diesel vehicles will be completely electric vehicles. For this reason, many studies have been conducted on electric vehicles. Particularly the change of the engine parts, the turning of the internal combustion part to the electric motor, and the design of these motors has become an important parameter. In order to improve the performances of electric vehicles, the batteries of electric motors have been improved. In this study, a simulation was carried out to conversion 1.3 JTD and 1.3 Multijet motors to electric vehicles and the performances of these forms are evaluated by comparing the motor power, torque, and speed of the two vehicles. It was tried to predict what kind of changes will be achieved by conversion these two cars into electrical forms. PID controllers were used for inspecting components. In the study including detailed calculations, the program named AVL Cruise was used. The findings have shown that the quality of the new electric vehicle equipment used instead of the internal combustion engine can also affect results. The graphs from electric vehicles were explained and compared in detail. It was observed that there may be significant differences in the efficiency of the vehicles as a result of the conversion of the internal combustion engine to the electric motor. This made the biggest difference between the two vehicles. Since there is no data related to the sale prices of vehicles in the case of the conversion internal combustion vehicles to electric vehicles, comparisons were performed only on equipment. The latest price information of the vehicles has not been discussed.","PeriodicalId":9652,"journal":{"name":"Celal Bayar Universitesi Fen Bilimleri Dergisi","volume":"25 1","pages":"901-906"},"PeriodicalIF":0.0,"publicationDate":"2017-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80914925","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}
