  • Evaluation on the Usage and Future of 5G Technologies in Smart
           Agricultural Systems

    • Authors: Dilek ÇAKIR; Mehmet Serhat ODABAS, Gökhan KAYHAN, Recai OKTAŞ
      Abstract: Nutrition, which is one of the first human needs, emphasizes the importance of agriculture. However, the ever-increasing human population and the decrease in agricultural areas necessitated the necessity of different approaches in agriculture. For this reason, research was conducted to improve the sustainability of agriculture and its productivity by using mobile internet connections, the internet of things (IoT), and artificial intelligence (AI) in the agricultural sector. This study attempts to distinguish 5G technology by evaluating the approaches to innovations in the field of agriculture between 2017 and 2021 in terms of technology. Thanks to the high-speed data transmission provided by 5G, a study has been carried out to provide sustainability and increase efficiency by saving time, cost, and labor in a more comprehensive, accurate, and timely manner in harvesting, weed detection, irrigation, and spraying applications with real-time data transmission.

  • Molecular Characterization of Gram Negative Isolated from Walnut (Juglans
           regia L.) Rhizosphere

    • Authors: Belgin ERDEM; Elif SEVİM, Ali SEVİM
      Abstract: In this study, 10 Gram negative bacteria isolated from the rhizosphere soil of walnut (Juglans regia) orchard in the Kırşehir (Central Anatolia of Turkey) were identified at species level by classical and molecular methods. It was determined that 99% of phylogenetic similarities with bacterial isolates were closely related to the isolated Gram negative bacterial isolates. Ten isolates were morpho-biochemically and molecularly characterized and on the basis of 16S rDNA sequencing were identified as 3 Enterobacter cloacae, 3 Enterobacter ludwigii, 2 Escherichia coli, 1 Enterobacter hormaechei and 1 Plesiomonas shigelloides. Gram negative bacteria showed enzymes activities. Except for P. shigelloides and E. coli, other Gram negative bacteria showed lipase, protease, cellulase, amylase, gelatinase and pectinase activities at 4 °C and 28 °C. As a result, the current research suggests that strains isolated from walnut rhizosphere soil can be used as bio-fertilizing and bio-control agents.

  • Determination of Nitrate, Nitrite and Ammonium in Water Collected from
           Ruminant Farms in Kırıkkale Province

    • Authors: Hatice AKAY SARIKAYA; Ebru YILDIRIM, Emine BAYDAN
      Abstract: The organic substances in drinking water should be at a level that will not harm human and animal health. This study was carried out with the aim of determining the levels of some inorganic substances (nitrite, nitrate, ammonium) in the water taken from 59 cattle farms within the borders of Kırıkkale Province and to have an idea whether they are at a level that will have a positive or negative effect on the health of the animals consuming these materials. The analyses were performed by ion chromatography device. The average values determined were as follows: nitrite was found in 2 (3.39%) samples with an average of 1.64±1.61 ppm, nitrate was found in 59 (100%) samples with the average value of 42.35±38.87 ppm, and ammonium was found in 3 (%5.08) samples with an average value of 22.86±12.38 ppm. Levels for nitrite were in the range of 0.50-2.79 ppm, and 2 (%3.39) samples exceed the level of 0.5 ppm. No sample exceed the level of 10 ppm which can pose a risk for animals. In 19 (32.20%) of the 59 samples nitrate level exceeded the level of 50 ppm, in 7 (11.86%) samples nitrate levels exceed the level of 100 ppm which is the recommended limit level for animals, and in 5 (8.47%) samples nitrate level exceeded the level of 125 ppm which may pose a risk of chronic poisoning in animals. For ammonium 3 samples (5.08%) exceeded the 0.5 ppm. As a result, it is suggested to monitor the water consumed by animals in order to increase the economic status of livestock enterprises.

  • Effect of Varying Percentage Increase in Reinforcement on Some Mechanical
           Properties of Die Cast Aluminum Alloy Composites

    • Authors: Francis INEGBEDİON; Precious Okwuoma AIBUEKU, Bright Omokaro OSAMWONYI
      Abstract: The die-casting process is a metal casting processes that utilize metal molds or permanent dies. In this work, the effect of varying percentage increase in reinforcement on some mechanical properties of aluminum alloy composites was obtained by the die cast process. The process was applied to produce various casts using aluminum alloy as the metal matrix and sawdust as the reinforcement at 5%, 10% and 15% by weight. Aluminum Scrap was sourced and sent for elemental characterization at Engineering Materials Development Institute (EMDI), Akure Nigeria. Tensile and hardness test were the mechanical tests carried out on the different samples of the cast. The elemental characterization test result showed that, the composition of the aluminum alloy used is Al-8.1%Mg-0.4%Fe-0.2%Zn. Results showed that at 10% by weight of reinforcement, the average tensile strength of the composite had the highest value while the lowest tensile strength was recorded at 15% by weight of reinforcement. At 15% by weight of reinforcement, the average hardness of the composite had the highest value while the lowest hardness was recorded at 5% by weight of reinforcement. Results were compared with the works of Ranjit et al. (2020) and Belete et al. (2013) and it was concluded that the results obtained from this work are adequate and significant for use.

  • Multidimensional Scaling Analysis and an Application

    • Authors: Gülşah KEKLİK; Mustafa ŞAHİN
      Abstract: The aim of this study is to determine the factors affecting student’s failure. For this, a survey study was carried out. In the questionnaire applied to people of all ages and occupations living in Turkey between 2013 and 2015, inferences were made on the answers of 4183 people, 2928 of whom were men and 1255 were women, regarding the relationship between 26 variables that are closely related to the success factor. In this study, non-metric multidimensional scaling technique was used considering the Euclidean distance. This is because the data is not quantitative and smaller size solutions can be obtained. As a result of the analysis, Kruskal's stress value was observed as 0.00 and no significant difference was observed between the variables. Therefore, the observation of stress values in the range of (0-0.025) clearly reveals that there is a "complete" agreement between the variables. Another one words, the measure of the actual figure compatibility chart obtained S=0.00 and shows full compliance. In this case, we can say that the results obtained adequately reflect the data set we have.
