Authors:Alime BAYINDIR EROL; Mehmet Sinan ARUSOĞLU, Ali Kemal BİRGÜCÜ Abstract: Aphis gossypii (Hemiptera: Aphidididae), which is harmful to the cotton plant, causes economic damage by sucking the buds and leaves of the plant with its stinging-sucking mouth structure. There are many control methods to reduce the damage of this pest on cotton below the economic damage threshold. One of them is chemical control method. In this study, the effect of insecticide application on the population density of A. gossypii to irrigation duration in cotton areas was investigated. The study was carried out in Eyyübiye district of Şanlıurfa province in 2019. The experiment was carried out on 150 decares, 10 decares of this area was divided into 2 blocks and insecticide application with Acetamiprid active ingredient was applied to the irrigation duration. The experiments were carried out with 20 replications and counts were made according to the results of the insecticide application. As a result, it was observed that the insecticide application applied to the cotton aphid population before irrigation was more successful. The results point out that more successful chemical control can be made against A. gossypii with the insecticide applied before irrigation. PubDate: Fri, 31 Dec 2021 00:00:00 +030

Authors:Şehnaz ŞENER; Sıla BEKTAŞ Abstract: In this study, hydrogeochemical properties of drinking water resources of Antalya province were examined and health risk assessment was performed. The hydrogeochemical properties, usability and quality status of the waters were examined using the analysis results of drinking water taken from pump stations and springs in May (2020) and October (2020). The waters in the region are Ca-CO3 and Ca-Mg-HCO3 waters. The analysis results of the waters were compared with the drinking water limit values determined by TS-266 (2005) and WHO (2011). According to TS-266, it has been determined that the waters are generally drinkable. However, it was determined that the waters exceeded the WHO (2011) limit values in terms of Mg, HCO3 and TDS values. The "Health risk assessment method" developed by USEPA was used to assess the health risk of the waters and determine their effects on human health. It has been determined that the waters in the study area do not pose a serious risk for human health, but the As content of the waters taken from the tanks is partially high. In addition, it is not recommended to consume these waters, especially by children. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Erhan ŞENER; Ayşen DAVRAZ Abstract: Drought, the effects of which are starting to be felt in increasing amounts today, is one of the most important natural disasters that threaten life. It is extremely important to regionally investigate the drought, which is expected to have intense effects, especially in the Mediterranean belt, and to develop adaptation strategies. Within the scope of this study, drought analysis for Isparta province was carried out with different index methods by using long-term meteorological observation data of Isparta State Meteorology Station (DMI). According to the results of the drought analysis performed at different time scales using Standardized Precipitation Index (SPI), Rainfall Anomaly Index (RAI), Percent of Normal Precipitation (PNI) methods, it was determined that extreme and severe dry periods were experienced in the region in 2008-2009. According to the analyzes made on a 1-month time scale, an extremely dry period has been experienced in 24 different time periods with the standardized Precipitation Index, 43 with the Rainfall Anomaly Index, and 234 with the Percent of Normal Precipitation. In addition, it was determined that there was a strong positive correlation between these indices. Similar results were obtained in meteorological drought analyzes performed at different time scales, especially using the SPI, RAI and PNI indices. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Merve MUTİ İSTEK; Selda BULCA Abstract: Various contaminations caused by food contaminants such as pathogenic bacteria, heavy metal ions, mycotoxins, antibiotics and pesticides pose serious threats to food safety and human health. The frequent occurrence of food safety problems as a result of food contamination has become a concern for both consumers and the food industry. Many qualitative and quantitative detection methods have been developed to control and prevent food contamination problems. These methods include analysis methods such as Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC). However, due to the disadvantages of these methods such as being costly and complex, requiring skill, taking time, and pre-processing the samples, biosensor techniques have become more preferred methods in food contamination analysis in recent years compared to others. In this study, electrochemical biosensor applications developed for food contamination analysis in recent years have been investigated and various informations are given.

Authors:Mehmet Fatih DEMİRAL Abstract: Whale Optimization Algorithm (WOA) is a fairly new algorithm developed in 2016. WOA was applied to continuous optimization problems and engineering problems in the literature. However, WOA demonstrates lower performance than others in traveling salesman problems. Therefore, in this study, an application of the hybrid algorithm (WOA+NN) has been done in the traveling salesman problem. A set of classical datasets which have cities scale ranged from 51 to 150 was used in the application. The results show that the hybrid algorithm (WOA+NN) outperforms AS (Ant system), WOA, GA, and SA for 50% of all datasets. Ant system (AS) is the second algorithm that is better than other metaheuristics for 40% of all datasets. In addition, it was given that a detailed analysis presents the number of best, worst, average solutions, standard deviation, and the average CPU time concerning meta-heuristics. The metrics stress that the hybrid algorithm (WOA+NN) demonstrates a performance rate over 50% in finding optimal solutions. AS (Ant system) is better at 40% of all optimal solutions. Finally, the hybrid algorithm solves the discrete problem in reasonable times in comparison to other algorithms for medium-scale datasets. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Ebru AYDOGAN DUMAN Abstract: The task of reducing noise from an image is known as image denoising. Although there are various methods and algorithms proposed in the literature, the methods still have limitations. The approaches generally either fail to reduce noise adequately or cause to be lost while effectively reducing noise. Conventional methods have poor performance when considering the success of preserving region boundaries and small structures. Conversely, modern techniques are more effective to smooth images without over smoothing edge details. To address these deficiencies and benefits, in this paper, we aim to develop a framework, which is capable of detecting whether a pixel is a part of edges or textures in an image so the framework can decide which filter should be used depending on region information. The Rank Order Test Method is used to detect image edges. In this way, we determine both which neighbors should be included to build a filter mask in the calculation for each pixel and which filter method should be implemented. We have compared the performance of Bilateral Filter-based methods. Experiments demonstrate that the proposed framework outperforms in terms of both PSNR, SSIM and visual perception for the noise with standard deviations 10, 30, 50. While the average PSNR value was 30.33 DB for the proposed model, the method with the closest result achieved an average score of 28.33 DB. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Asım Gökhan YETGİN Abstract: Switched Reluctance Motors (SRMs) have been used frequently in industrial applications in recent years. Especially electric vehicles and domestic applications are also encountered. Although SRM is being used so widely, one of the biggest disadvantages is the torque ripple that occur. In order to reduce the torque ripple, it is tried to be reduced by making improvements both during the design of the motor and in the control parts of the motor. Tangential force is effective in the formation of the torque. For this reason, determination and analysis of the force in this direction is of great importance for motors. In this study, the effect of the air gap length value of the switched reluctance motor on the radial and tangential force values was analysed using the maxwell stress tensor method. The optimal air gap length has been tried to be determined. Switched reluctance motor with 550 W, 8/6 pole numbers are used. Radial and tangential magnetic flux density values and force values of each motor model were obtained. According to the results, it was determined that with the increase of the air gap length, both radial and tangential force values decreased. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Belgin TUNALI; Deniz TÜRKÖZ ALTUĞ, Neslihan KAYA KINAYTÜRK, Gökhan TÜZÜN Abstract: Since copper and lead are the most well-known heavy metals, eggshells were used to remove them from the aqueous solution. In this study, it was used two species; Quail (Coturnix coturnix japonica) and Greylag Goose (Anser anser) and three forms (pure, powdered and calcined forms) of eggshells. Using coupled plasma optical emission spectroscopy (ICP-OES), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) methods, it was investigated whether copper and lead were adsorbed on eggshells; in different species and different forms. According to ICP-OES results, it was observed that calcined eggshells retained more amount of Cu and Pb than uncalcined eggshells. By analyzing the FTIR results, even if the eggshells were in different forms, the characteristic bands of the eggshells were almost seen in samples. After the adsorption process, new bands arose in addition to the characteristic eggshell bands. These new bands are thought to be related to the Cu and Pb loading in the eggshell. With SEM images, it was observed that metal loaded accumulated on the outer surface of the eggshell. This result is also in good agreement with the EDS results.

Authors:Anıl EVCİ; Candan ŞAHİN Abstract: Drought is an important event affecting the economic structure, sociocultural characteristics and ecological structure of a society. As a result of droughts dangerous situations are inevitable such as; drying of rivers and stream beds or damage to their flows, increased pressure on plants, decreased agricultural productivity and natural life activities, increased migration. It is possible to minimize these negative effects with certain size estimates of the drought. There are many methods used to describe the spatial and temporal characteristics and severity of drought. The most preferred of these methods is the "Standardized Precipitation Index (SPI). In the study, drought analysis was made for Salda Lake Basin using the Standardized Precipitation Index method. SPI values were calculated according to the data of Yesilova meteorology station in “1-3-6-12-24” month time periods. According to the results of the analysis, the most severe and longest droughts were observed between "1989-1995". When the droughts experienced in the last 10 years are evaluated, it is predicted that there may always be a drought close to normal in the area. PubDate: Fri, 31 Dec 2021 00:00:00 +030
Authors:Gülten Ece TURGUT; Murat ZENGİN, Veysel DAĞ Abstract: In addition to the natural beauties offered by an area, its visual effect can affect the users' experience of the area. Determining and evaluating the quality in terms of visual landscape, protecting it and transferring it to the use of future generations and ensuring the continuity of the urban ecology have gained importance today. In this context, in the study, in which the perception of landscape is handled visually, 9 common usage types have been determined in 4 recreational areas (Çamlık Urban Forest, Cable Car/Bağbaşı Plateau, Ornaz Valley Picnic Area and Servergazi Recreation Area) that are used extensively in Denizli City. In order to evaluate the visual landscape quality of these uses, a survey was conducted through face-to-face interviews with 271 people in Merkezefendi and Pamukkale districts of Denizli City Center. The results obtained according to the level of appreciation were evaluated separately for each area and usage type. As a result of the evaluations, Ornaz Valley well-maintained surface/areas (87.5%) were the most preferred usage type, while the Cable Car/Bağbaşı Plateau well-maintained surfaces/areas (8.4%) were determined as the least favorite usage type. The aim of this study is to reveal whether the landscape structure of some recreation areas in Denizli is related to the perceived visual quality. As a result of the survey conducted for this purpose, it was determined that the landscape structure of the recreation areas of Denizli city is related to the perceived visual quality. As a result, considering the visual landscape quality evaluations according to the landscape perception and preferences of the users, suggestions have been developed for the existing and future recreation areas.

Authors:Hüseyin ASİLTÜRK; Ali Hakan IŞIK Abstract: With the Covid-19 pandemic, many requirements are carried out according to distance and social distance rules. These rules are applied in many areas such as education, work, market shopping. Polling or voting may also become mandatory in this process. Today, most of the surveys are carried out through electronic systems. Users can exchange own ideas without any contact with the created surveys. A survey system was created in our study. In the study, advanced security of the survey records was ensured by storing the data on the smart contract that is created in the ethereum network using the blockchain infrastructure. In the study, while ensuring the security of user data, ease of use was also provided. Web3.js, Bootstrap and MVC technologies were also used for web interfaces in the study. Data recording was done in two fields to ensure flow. One of them is ethereum-based smart contract and the other is MySQL database. User data first requests registration to the block network. During this time, the data is saved in the MySQL database so that the user does not wait until the record is registered in the network. Thus, the user does not have to wait and can continue with his transactions. When the user wants to control his data from the system, the control module is requested to compare the data in the ethereum test network with the MySQL data. If there is a problem after the comparison, the administrator checked the profile key and the record in the blockchain network, which provides full security, was accepted as correct. The study contributes to the literature by providing the highest level of security for the user data in the survey. PubDate: Fri, 31 Dec 2021 00:00:00 +030
