Ayşen Akay | Mohammed Yashar Omar
High concentrations of chromium in the soil have a toxic effect on the living organisms in the soil ecosystem. If chromium, which is not an absolute essential element, accumulates in plants, it causes structural changes, causing a decrease in plant growth and also high toxicity due to its accumulation in biomass. Use of plants to remove chromium (Cr) from contaminated soils, it is an environmentally efficient, cost-effective, modern, applicable technique. The different species of plant and ornamental plants are used in this technique. In this study, the Kordes shrub rose used in landscaping in our province, Cr phytoremediation capacity was evaluated by growing at contaminated soil with Cr. In the study, the different doses of Cr (0, 50, 100, 500, 1000 mg kg-1) have been applied in Cr+3 and Cr+6 forms. In addition, two doses (0% and 3%) of leonardite were added to the pots to determine the effect on the developmental status of the plants and Cr uptake. In the study, plant height, number of branches, number of flowers, flower diameter, stem diameter, flower yield values and total wet and dry weight values at the end of the experiment were determined. At the end of the experiment, it was observed that generally developmental status of the plants was adversely affected at high Cr doses. Especially at 500 and 1000 mg kg-1 application doses was observed that the plants could not withstand Cr toxicity in a short time. It has been observed that plants treated with leonardite were healthier than those without. According to the data obtained at the end of the study, it was determined that the resistance of plant to high doses of Cr was low, but it showed better growth at 50 and 100 mg kg-1 doses.

This study aimed to analyze the spatial perception of educational buildings with historical significance by users. In this context, Antalya Vocational and Technical Anatolian High School, which is a historical building, was discussed as a material. A questionnaire was applied to individuals who graduated from this high school to examine how the facade design and garden layout were perceived in the spatial evaluation of the high school discussed in the study. Three different facade designs (modern, traditional, and mixed) based on the building complex were prepared using the AutoCAD, 3D Max, and Photoshop CS3 programs to be used in the questionnaire form consisting of open-ended and closed-ended questions. The frequency analysis was performed using the SPSS program to evaluate the data obtained after the questionnaire. According to the obtained results, it was determined that the middle age group was highly interested in the traditional and mixed facade design. It was observed that the participants further preferred the modern facade design as their level of education increased. It was observed that the participants preferred the mixed facade design more as their income level increased. Furthermore, it was determined that the mixed facade design was generally preferred more by the participants. In conclusion, the quality of historical buildings from the past should be updated with a modern perspective. Thus, positive effects will be achieved for the continuity of the building and its compliance with the environment. It is foreseen to provide positive effects both in terms of functionality and in the field of visual admiration and comfort by evaluating the changing needs of society over time and environmental factors together. On the other hand, while positive elements ensure the continuity of buildings and building complexes, it will also be possible to contribute to their becoming an urban image.

Gülten Tiryaki Gündüz | Burcu Sıla Göral
Grape pickle is a traditional food that is made with grapes (Vitis vinifera), horseradish (Armoracia rusticana) and grape syrup. In this study, the survival of Bacillus cereus and Escherichia coli in grape pickles produced with or without using probiotic Lactobacillus acidophilus La-5 as well as microbiological, chemical and sensory properties of each group were examined during 35 days of ripening at 25°C and 5 months at refrigerated storage period. Molds and lactic acid bacteria (LAB) counts remained below the limit of detection (6 log in samples to be considered a probiotic product. E. coli counts rapidly declined to undetectable level within 7 days, while B. cereus numbers was found 1.56-1.72 log cfu/g at the end of the storage period. As a result, it was established that traditional grape pickle is not suitable food matrix for probiotication. High total soluble solid content (63 °Brix) and presence of horseradish in grape pickles ensure the microbiological stability as well as the safety of product.

Fırat Kömekçi | Adnan Değirmencioğlu
The objective of this study was to find out the effects of torque rise on lugging ability of tractors. In British terminology, torque rise refers to torque back-up or torque reserve. Torque rise is the amount of torque that the engine can produce above the manufacturers rated amount of torque. It is the percent increase in torque, from rated torque to peak torque. In order to meet the above objective, two tractor reports issued by Nebraska Tractor Test Laboratory were used. Powertrain schemas obtained from three different tractor manufacturers were used and the total transmission ratios from these schemas were calculated. The effect of torque rise on lugging ability of the two tractors with four different gear boxes was studied. From the study, it was concluded that higher torque rise enables the tractor to run in a wide range of torque and the gear box to be chosen should be such that it can match with the engine.

Row planting is one of the technologies introduced in Ethiopia to improve production and productivity of the major crops. However, the rate of adopting the technology decline from time to time. Thus, this study aims to identify factors affecting adoption level and intensity use of Teff row planting technology in the selected districts of North Shewa Zone, Ethiopia. Multi-stage random sampling techniques were used to select 400 respondents. Adoption index, independent sample mean t-test, chi-square test and double hurdle model were used for data analysis. The results of adoption index reveals that among 400 sample households, 79.8% was non-adopter while 20.2% were adopter of Teff row planting technology. A total of 10 variables were hypothesized to affect the adoption level and intensity use of Teff row planting technology in the study area. Among these, 6 variables had significant effect on adoption level of Teff row planting technology while 4 variables had significant effect on the intensity use of Teff row planting technology. Accordingly, the experience of household in Teff production, education level of household head, family size, extension contact, credit utilization and demonstration site visit had positive and significant effect on the adoption level of Teff row planting technology adoption at 1, 1, 5, 1, 1 and 1% significance level respectively. Moreover, family size, education level of household head, frequency of extension contacts and demonstration site visit had positive and significant effect on the intensity use of Teff row planting technology at 10, 1, 1 and 1% significant level respectively. Hence, in order to increase the households’ adoption level and intensity use of Teff row planting technology in the study area, strengthening the extension services, improving the education level of the households, strengthening the credit services and expanding the demonstration site should be the focus area of the policy makers.
Mostrar más [+] Menos [-]Current Approaches to Nitrite Reduction Methods in Meat Products and Their Potential for Transfer to Industry Texto completo
2022
Gülen Yıldız Turp | Tuğçe Avcı
Nowadays, consumer demand for healthy and natural food is reflected in the meat industry and researches and investments on this issue have gained speed. Nitrite is a widely used synthetic additive in meat products due to its contribution to the development of characteristic color and flavor, controls lipid oxidation and has an antimicrobial effect on pathogenic microorganisms, especially Clostridium botulinum. However, the fact that nitrite causes the formation of toxic, mutagenic and carcinogenic N-nitrosamine compounds and constitutes a risk to human health has led to the searches for alternative additives. An important part of the studies on this subject consists of testing the use of natural additives as an alternative to nitrite. In recent years, instead of using nitrate and nitrite in meat products, studies have been carried out to use organic acids and microbial resources. In addition to these methods, up-to-date technology applications such as high pressure, irradiation, encapsulation, active packaging containing nitrite, zinc protoporphyrin IX compound formation and cold plasma technology constitute other research areas that we encounter in reducing the nitrite rate in meat products. Within the scope of this review, the functions of nitrite in cured meat products, current potential methods for reducing nitrite content and the limitations of transferring these methods to industry were examined.
