This study was carried out in order to reveal the situation of aquarium sales enterprises in Elazig and to determine their problems. In the study, a total of 14 enterprises (aquarist) were asked questions by the survey method. It has been determined that a significant part of the existing enterprises is located in the center of Elazig (93%), all of them continue to operate as tenants and their operating periods are over 5 years. It has been noted that 86% of the personnel working in the enterprises are male and 14% are female. It was determined that the most sold fish species in the research area were 2 fish species belonging to 2 families. It has been observed that one of the important problems in aquarium businesses is fish diseases. It has been determined that 93% of the fish sales of the Covid-19 pandemic period were negatively affected and 7% were positively affected.

Iron (Fe) is an important micronutrient for plants, and its deficiency causes serious yield losses by inhibiting plant growth and development. Detailed studies have been carried out for many years on the uptake of available iron in the soil by plants and its transport to plant organs. These studies proved that Fe can be transported in chelated form with some organic substances including peptides and amino acids. However, detailed studies have not been conducted on the uptake of peptide- or amino acid-chelated Fe into the plant or its transport between organs. Few studies have focused on the oligopeptide transporter (OPT) and drug/metabolite transporter (DMT) families. The possible roles of the recently discovered UMAMIT amino acid transporter family have not been studied in iron transport in plants yet. In this review, the transporter families responsible for the uptake and translocation of iron were summarized. Then, the roles of the OPT, DMT, and UMAMIT families in transporting iron-peptide and iron-amino acid complexes were discussed in detail.

Compost is usually made of biodegradable wastes. Today, compost, bio-agent bacteria and mycorrhizae are used as the key components of sustainable agriculture. This study was conducted to determine the effects of compost treatments alone and combined with bacteria, mycorrhiza and commercial fertilizers on growth, flower and bulb quality parameters of the ‘Jan van Nes’ tulip cultivar. Compost was made of grape pomace and set at different EC levels. Three different compost ratios (0%, 20% and 40%), three different EC levels (0.75, 1.10, and 1.45 dS/m) and combinations with or without bacteria and mycorrhizae were experimented. Flower stalk length, perianth length and vase life were identified as the most striking parameters for growth and flowering of tulip plants. The best outcomes in terms of flower stem length (34.20 cm), perianth length (44.85 mm) and vase life (7.00 days) were obtained from 0% compost treatments. Increasing compost ratios had adverse effects on plant growth and bacteria and mycorrhizae treatments alone did not provide any significant effects. However, combining with different compost ratios increased the effectiveness of bacteria and mycorrhiza. EC of 0.75 yielded better results than the other EC levels.

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.

In this study, it was aimed to determine some physiological effects of CuO nanoparticle on C. demersum. The plants were collected from an uncontaminated pond in Gaziantep province. Different concentrations of CuO (0, 25, 50, 100 and 200 mg/L) were applied to the macrophytes after being acclimatized in controlled conditions. Some analyses were made on macrophytes harvested at the end of the application. The contents of protein, total carbohydrate, photosynthetic pigment, total phenolic compound, non-protein sulfhydryl groups of tissues increased with increasing CuO concentration under the influence of applied CuO concentrations. In addition, increases in hydrogen peroxide and MDA contents were also detected. As a result, it was determined that the applied CuO concentrations caused some physiological changes in C. demersum tissues.

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.

A comparative study between natural and synthetic environments is carried out by realizing six fermentation experiments in batch culture. The objective of this study is to consider the effect of carbon sources on growth and the production of glutamic acid by Corynebacterium glutamicum 2262. The difference between the culture media lies in the carbon source. Two natural environments of date juice, one of which is treated with invertase to hydrolyse sucrose with a concentration of total sugars of 88 g/L. Four synthetic media with a concentration of 34 g/L sugars: medium containing mixed sugars (glucose + fructose + sucrose) with rates proportional to that of date juice, the other three media are composed of a single sugar (either glucose, fructose, or sucrose). The results showed that Corynebacterium glutamicum is able to use the three sugars whether they are single or mixed, although the best results of glutamate production (8.41 g/L) are obtained on the mixture of three sugars, which explains the interest and valorisation of date waste. On the other hand, the date juice-based media are shown to have a glutamate concentration of 7.98 g/L during the hydrolysis of sucrose of date juice.

In the study; fruit skin color parameters, fruit flesh firmness and total soluable solid (TSS) ratios, as well as total acidity, total phenolic substance, total monomeric anth°Cyanin amounts and total antioxidant capacity were determined. After the fruits were harvested, they were immersed in three different doses (0-2-4%) of calcium chloride (CaCl2) solution for 5 minutes. The fruits removed from the solution were kept to dry. The fruits were stored for 14 days in a cold store with a temperature of 1-2°C and a relative humidity of 90±5%. Before the storage and on the 7th and 14th days of storage, the fruits samples were taken and kept on the shelves in the rooms with a temperature of 21±1°C and a relative humidity of 60±5%for 3 days. Measurements and analyses of fruit quality parameters were made in the samples taken from the fruits that were kept on the shelf for three days. As a result of the study, it was determined that 4%CaCl2 application was effective in maintaining fruit flesh firmness. In fruits kept on the shelf for 3 days after 14 days of storage, SSC of 4%CaCl2 treatment was found to be higher than the control treatment. Compared to the control, 4%CaCl2 caused a significant increase in the total phenol content. The highest total monomeric anth°Cyanin content and total antioxidant capacity was determined in the control treatment. While there were no significant changes in L* values between treatments, a* and b* values were found to be higher in 2%CaCl2 treatment. In the light of the data obtained, it was concluded that 4%CaCl2 application had a positive effect on the shelf life of strawberry fruits.

This study was carried out to determine the effects of plant growth-promoting rhizobacteria and mycorrhiza treatments on the development of Zinnia elegans L. ‘Zesty’ and Dahlia variabilis L. ‘Figaro Violet’ cultivars. In the study, a suspension was first prepared from bacterial isolates developed at 25±2 °C for 24 hours. The prepared suspensions were adjusted to an absorbance value of 0,3 at 600 nanometers in a spectrophotometer. D. variabilis seedlings were immersed in suspensions prepared from ZE-12, ZE-13 and ZE-12+ZE-13, Z. elegans seedlings were immersed in suspensions prepared from ZE-2, ZE-7, ZE-12, ZE-13, ZE-12+ZE-13 for 30 minutes. In addition, Z. elegans seedlings were kept in mycorrhiza prepared at a concentration of 5000 ppm for 10 seconds. At the end of the period, flower seedlings were planted in pots with a mixture of peat and perlite. As the control group, seedlings without rhizobacteria and mycorrhiza treatment were used in both cultivars. The experiment was established with 3 replications and 10 plants per replication. The applications made in the D. variabilis experiment remained the same as the control in all other parameters except root dry weight. ZE-13 application was effective on root dry weight. It was determined that the applications made in Z. elegans seedlings increased the flower stem thickness and the number of leaves, especially the ZE-13 application was the most effective application. In conclusion, with this study, it was revealed that rhizobacteria and mycorrhiza applications, which are of natural origin and do not harm the environment, have the potential to be used in ornamental plants cultivation, and that these applications should be expanded.

Trees in upland, semiarid agroecological zones typically require water efficiency due to low rainfall, cold and dry temperatures as in Niğde Province, Central Anatolia, Türkiye. This study quantitatively assessed farmer perception of ecosystem services and production advantage of trees in a semiarid zone. Forty-nine farmers in Niğde Province were surveyed. The survey evaluated two major factors: ecosystem services and production advantage using eleven indicators. The responses were grouped by age, gender, education, district class (rural and urban) and farm settlement (rural and urban) and were analysed by test of association (χ2) at P≤0.05. Most farmers had knowledge of trees in their environment and mainly supported the perspective that trees were important mainly for cultural and provisioning ecosystem services. However, they held the opinion that having trees on their farmer was a production disadvantage in a semiarid agroecological zone. Although there were no gender differences in their perspectives, there were significant difference by age, education, district class and farm settlement. Farmers in this semiarid agroecological zone seemed more interested in trees with evident ecosystem services and production advantage such as improved crop yield, water efficiency, weed and pest management, ease of harvesting as well as reduced overall production cost. By implication, trees with multiple benefits are required if further planting by farmers is to be encouraged for agroecosystem improvement. In addition, tree choice will be based on farmer perception of the benefits of trees for ecosystem services and production advantage and further research to identify and promote trees that benefits the widest range of agroecosystems.
