Assessing the Land Consolidation Projects from the Perspective of Farmers (A Case Study in Artova District of Tokat Province in Turkey) Texte intégral
2021
Esra Kaplan | Hayriye Sibel Gülse Bal
Land consolidation is a powerful and effective tool in solving the fragmentation problem of agricultural lands to form a larger, more rational and efficient land for the farmers. The benefits of land consolidation projects are providing access to parcels, efficient use of water resources, real location of parcels, and reducing the costs of irrigation and drainage projects. Although not sufficiently successful, the land consolidation projects in Turkey had been initiated in 1961. This study was aimed to measure and assess the knowledge, expectation and attitudes of farmers on the land consolidation project planned to be implemented for some villages in Artova District of Tokat Province, Turkey. The study was carried out in Taşpınar and Aşağı Güçlü villages which were included in the consolidation program. In these villages, 62 farmers were selected by proportional sampling method out of 175 producers registered in the Farmer Registration System (FRS) and, face to face questionnaires were carried out with them. The results indicated that the producers support the project primarily due to the convenience in irrigation and increasing the efficiency of mechanization. Chi-square analysis revealed that the problems caused by disadvantages of fragmented land structure, importance of land integrity and the experience on a previous consolidation project area are important for the producers supporting the land consolidation project.

2021
Elim Gamze Has | Mustafa Akçelik
Salmonella is known as one of the main factors of food-borne gastroenteritis, and with this feature, it poses a great risk in terms of public health and economic losses. It is estimated that of the approximately 94 million cases of salmonellosis occurring in the world each year (about 85 percent of these are food-borne), an average of 150,000 result in death. Current social trends highlight the important health benefits of fresh produce in our daily diet. As an irony; Uncooked consumption of fresh herbal products is increasingly identified as a source of transmission for pathogens of intestinal origin, and epidemics occurring in this way are spreading rapidly. Today, the frequency of anthropogenic pathogen outbreaks associated with fresh produce, spices, and nuts has surpassed those associated with foods of animal origin. Human pathogens in the production chain; It can be transferred to plant material by basic means such as the use of animal manure, contaminated irrigation water, biological vectors (insects and animals) and contaminated seeds. In the light of these data, many intestinal pathogens have been identified as phyllo sphere-associated bacteria. Despite all these findings, there are many unknowns on the persistence and infectivity of Salmonella in contaminated plant hosts. In this review article, the factors affecting the attachment, colonization and survival of Salmonella on plant surfaces, as well as the information on the infection processes that continue with the invasion of plant tissues are discussed in the light of contemporary literature data.

This study was carried out to determine the effects of ultraviolet-B (UV-B) and LED light on improving postharvest quality of 0900 Ziraat cherry fruits. In the present study, UV-B treated to cherry fruits 10, 20, and 40 min, and then stored dark conditions. On the other hand, the blue (M), red (KR) and ultraviolet-A (UVA) LED light had applied to fruit during storage, continuously. Fruits without application were used as a control. Cherry fruits were stored at 4±1°C temperature with 85-90% RH for 35 days. As a result of the study, the best treatment in terms of increasing the TSS/TA rate (19.3), fructose (5.27%), glucose (6.22%), total soluble phenol (170.16 mg/100 mL CAE) and anthocyanin content (12.11 mg/kg FW), red color, and taste quality (4.63) of fruits was UVB20. It has also been seen that the KR treatment could be used to reducing the titratable acidity content, and increase the amount of fructose, total soluble phenol. The UV-A LED treatment is particularly significant in reducing weight loss, and providing in the fruit stalk remains green. Also, the treatments of both UVB and LED improved the color quality of cherries by increasing brightness, darkening red color, and protection of anthocyanins, whereas increased the EL. As a result, it might be concluded that the UVB20 (5.95 kJ / m2s) treatment was the best and usable treatment to maintaining both biochemical and taste quality cherry fruits during cold storage.

2021
Debela Geneti Desisa
This study focuses on the investigation of enhancing convective heat transfer between the absorber and the air inside a channel. The investigation approaches modeling different absorber through CFD simulation and validating the result with experimental data. Supplying air to both sides of the top and the bottom surfaces of the absorber increase the air mass flow rate and therefore increases the thermal efficiency of the dryer. The studies in a V-grooved absorber attain high hot air velocity; high thermal efficiency resulted from high turbulence created in the duct. For the sample taken with a flow range, 0.01kg/s to 0.06 kg/s, the high output temperature was observed in a lower temperature range and increases as the flow rate increases. At a flow rate 0.01 kg/s, the velocity of hot air passing over the V-grooved absorber attain 0.28 m/s and increased to 1.4 m/s as the mass flow rate increased to 0.06 kg/s. For the rectangular absorber, the velocity of hot air attains 0.15 m/s at a flow rate of 0.01 kg/s and increased to 1.46 m/s as the mass flow rate increases to 0.06 kg/s. The double-sided V-grooved absorber contributes 8 – 12.40% value more efficiency compared to the rectangular plate with the same flow orientation. Further investigation is recommended taking the quantitative analysis obtained in this study and generating qualitative data.

Determining the potential bioavailability of heavy metals, evaluating according to adapted regulations is essential to efficiently conserve our coastal and estuarine waters. In this study, it is aimed to determine the industrial pollution and various other pollution sources that the Black Sea Basin is exposed to by using DGT (Diffusive Gradients in Thin Films) method and grab (manuel) sampling method in water and sediment and to evaluate the existing pollution according to quality standards. In Samsun, seasonal samples were collected from five different sampling stations, namely Akkiraz Stream, Hıdırellez Stream, Organized Industrial Zone (OIZ) Channel, Şabanoğlu Stream and Selyeri Stream, which are selected from Tekkeköy region where industry is intensively active. In order to determine the heavy metal content in both water and sediment samples, the DGT method was chosen for passive sampling and the grab sampling method was used for active sampling, and the efficiency of the methods was evaluated. According to the results of the study, the heavy metal concentration in grab sampling for water samples in descending order Al> Fe> Zn> Pb> Ni> Cu; In the samples taken with DGT, they are listed as Al> Fe> Zn> Cu> Ni> Pb. There were significant relationships between the total metal concentrations of sediment (Csed) and water (Csu) in grab sampling and metal concentrations sediment (Csed-DGT) and water (Csu-DGT) measured by DGT. It was found that the sensitivity and performance of sampling with DGT was 2-10 times higher compared to grab sampling. The high resolution in situ DGT technique for the assessment and management of the potential release risk of heavy metals at the water-sediment interface is a complementary method that contributes to the standard grab sampling method.
