Elif Bozdoğan Sert
In recent years, it has gained importance to develop models to determine the contribution of parks to reducing the temperature together with their surroundings. ENVI-met, which is used for this purpose, allows simulations for different conditions/materials with projections over many years. This study aims to determine the temperature levels arising from the surface materials and the projections of long years in the near areas of Cumhuriyet Park in Çukurova District of Adana. The study consists of 3 stages. In the first stage, information about the subject was gathered together. In the second stage, modeling was carried out using ENVI-Met 4.4.5 climatic simulation software in order to determine the temperature levels caused by different materials in the study area. The scenario for the future has been put forward. The data obtained in the third stage of the study were evaluated and suggestions were presented. As a result of the study, it was determined that Cumhuriyet Park, which is one of the important green areas of Çukurova district, contributed significantly to the decrease in the temperature level around it. This contribution is felt more intensely especially in the immediate vicinity of the park. It has been shown that the effect decreases with distance from the park. In the scenario put forward at the end of the 28-year period, it is predicted that the temperature level of the parking area will increase by approximately 2.4°C. This study reveals the importance of the selection of soil materials in preventing the warming of cities because of climate change experienced all over the world. In this context, local administrations attach importance to efforts to increase the quality of urban life; developing strategies in this regard is important for achieving results.

Zeynep Kilci | Ramazan Ülkü Çetin
Tahini is a food product that is frequently preferred both directly and as a main ingredient in various ready-to-eat food products and is consumed with interest, especially in the Middle East geography. Its reputation has recently spread across continents to countries like Canada and the United States of America. Tahini was subjected to a number of analyses to ascertain its physicochemical and microbiological quality within the context of the study since it is a highly consumed product with high consumption and demand values. In this context, tahini samples of 10 different brands were collected from producers and commercially sold markets in Balikesir and Bursa. Samples were taken from two different lot numbers for each company. As a result of the analyzes made on the tahini samples, it was determined that the total oil amount of the samples changed between 49.76-58.7%, the salt amount changed between 0.001-0.0027%, the ash amount was between 1.02%-1.28%, and the moisture value was between 1.1-1.5%; as a result of microbiological cultivations in which the presence of yeast and mold were analyzed, an average of 75 CFU/g viability was determined, while Escherichia coli, which was screened as an indicator of fecal contamination, Staphylococcus aureus and Salmonella spp, which are pathogenic microorganisms, were not found to be contaminated in all tahini samples. One of the tahini samples was not found in accordance with the Turkish Food Codex Tahini Communiqué (TFC) in terms of the amount of oil. It is concluded that 90% of the samples were manufactured in line with the TFC when the results of the chemical and microbiological analyses were combined.

The objective of the present study was to determine the relationships between animal welfare score (AWS) and milk somatic cell count (SCC) in Anatolian buffaloes. The study carried out on 39 buffalo farms of Bafra district of Samsun province of Turkey between January and March 2020. To obtain AWS data, a scale with 1 to 100 points (1-25: poor, 26-50: moderate, 51-75: suitable and ≥76: excellent) was used. Locomotion ability (LA), social interaction (SI), flooring (F), indoor conditions (IC) and effect of stockman (S) were used to be AWS parameters. Milk samples were analyzed by SCC using a portable cell counter. The SCC values were transferred to log10 base before the analyses. To assess the effects of AWS on logSCC, independent sample t-test was performed. The relations of all parameters with each other were calculated by Kendall rank correlation method and the statistical analyses were carried out by SPSS 17.0. The highest and the lowest means were obtained from SI (79.66±1.28) and F (61.79±2.51), respectively. While the highest correlation was estimated between IC and AWS (r=0.724), all AWS parameters had approximately moderate relations with AWS. Positive or negative, but insignificant correlation coefficients were estimated between any traits and logSCC. The means of SCC (136841±15522 cells/ml) and AWS (68.70±1.67) of the present study were found within the suitable thresholds. Routinely keeping the records on AWS and its components, and adding AWS data to the herd management programs was suggested to the buffalo farm owners.

The degradation of some pesticides (acetamiprid, boscalid, deltamethrin, kresoxim-methyl, pyraclostrobin and pyridaben) by Enterobacter cloacae (plant growth-promoting bacteria) was investigated in vitro. In this study, firstly the effective substances used initially did not have a negative effect on E. cloacae, and the bacteria showed the same growth as the control group in the nutrient agar medium. Secondly, application doses of pesticides were added to erlenmeyer with nutrient broth, and 1 ml of 1×109 cells/ml of E. cloacae solution was inoculated and incubated in a shaker at room temperature (24°C) for 7 days. After the nutrient broth medium was extracted, pesticides were measured by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). When the results were compared with the control group, there was no degradation in acetamiprid, but 98.9% in pyraclostrobin, 98.6% in boscalid, 94.1% in kresoxim-methyl, 73.5% in pyridaben and 57.3% in deltamethrin. It is thought that the results of this study and the information obtained on the degradation of boscalid, deltamethrin, kresoxim-methyl, pyraclostrobin and pyridaben will shed light on future studies.

2022
Hatice Çınar | Mine Sungur
In this study, the project studio, which is the foundation of interior design education, has been designed using the metaphor method, one of the intellectual methods applied in education. The metaphor method is a technique used to make difficult-to-understand abstract concepts concrete and helps design students develop their critical thinking and creative skills. In this case, design, which is the verbalized form of abstract thought, is limited to an object and the responsibilities brought by this object. From this point of view, an experimental study of metaphorical methods for establishing spatial relations of objects was carried out in a 14-week design studio with the 2nd year students of the Department of Interior Architecture, Faculty of Architecture and Design, Selcuk University. The purpose of the studio work is to draw the boundaries of interior architecture students in their search for solutions to design problems, and to enable them to come up with creative designs while making functional and formal decisions. In this context, a metaphorical approach was used in the context of object-space relations to guide students’ formal decisions in the functional solutions of the problems that arise in the interior design process. After working in the studio, the students have developed a working doctrine that will guide their interior design studio projects using the designed method, allow them to create unique forms and shapes, enable them to translate abstract ideas into concrete space and make it possible for them to design at various scales, from equipment to space design. The method is at a level that will set an example for students, designers and academicians working in the design discipline.

Belma Doğan Öz | Gamze Saner
The aim of this study is to determine the indicators used to determine the sustainability levels of nut farms and to establish a set of indicators that can be used to measure the level of sustainability of pistachio farms, based on the literature review. As a result of the literature review, among the indicators commonly used to measure agricultural sustainability, a total of thirty sub-criteria were identified, including fifteen sub-criteria for the economic aspect (farm size, yield, etc.), six sub-criteria for the environmental aspect (pesticide, fertilizer, water, energy usage, etc.) and nine sub-criteria for the social aspect (farmer’s age, education, etc.) which can be used in evaluating the sustainability of pistachio cultivation. According to this study's findings, although the theoretical principles, dimensions, and goals of agricultural sustainability are globally adaptable, the applicability of the indicators may vary between regions and countries due to geographic, climatic, and socio-cultural differences. Therefore, the sustainability assessment process requires special attention. Sufficient knowledge and expertise are required in setting goals, selecting indicators, and verifying indicators.

Moringa oleifera Lam. is one of the most used plants in traditional medicine because of its high antioxidant properties. The antioxidant value, nonetheless, depends on locality where the plant is grown as well as specific parts on the plant. In this study, a phytochemical and antioxidant activity comparison of M. oleifera leaves, seeds and barks were carried out. Fresh leaves, seeds and barks were collected from 2 to 3 years old M. oleifera trees of Bukavu city of South Kivu province in DRC and Masii village of Machackos County in Kenya. A total of 300g of each dried sample powder was mixed with 700 mL of distilled water. Qualitative and quantitative assessment of alkaloids, saponins, phenols, flavonoids, glycosides, terpenoids and tannins were performed following standard methods while the antioxidant activity was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Results indicate that only alkaloids were absent in leaves from Kenya and DRC while phenols, flavonoids and tannins were absent in barks. Glycoside in seeds from DRC had the highest concentration (6.17%) followed by alkaloids in seeds from Kenya (5.56%). There was low concentration of terpenoids and flavonoids in all samples compared to other compounds. The highest extract yield was found in leaves from DR Congo (22.5%) and seeds from Kenya (20%). At the highest concentration (10 µg/mL), leaves from Kenya (88.29±1.12 µg/mL) and DRC (80.17±3.59 µg/mL) had the highest percentage inhibition of reactive oxygen-free radicals but lower than the reference standard (92.63±2.76 µg/mL). Leaves from Kenya (23.59 μg/mL) and DRC (28.67 μg/mL) had the highest IC50 compared to mean values of seeds and barks from the two countries. M. oleifera leaves, especially from Kenya, are recommended as a satisfactory antioxidant but can be substituted with seeds and/or barks in order to alleviate the use of leaves which are overused these days.
