2020
Ülviye Çebi
This study includes some deep underground well waters opened to supply the irrigation water in Tekirdağ province. The sampling was done from 22 wells in the irrigation season period. The parameters such as pH, EC, TDS, Na, Ca, Mg, K, Cl, HCO3, B, NO3-N, Sodium Absorption Ratio and Residual Sodium Carbonate parameters, which were significant in terms of irrigation water classification, were examined in the samplings. According to the results, it was determined that thirteen well waters were in medium salty and eight well waters were in high salty water classes. Besides, Na and HCO3 harms were determined in five and three well waters, respectively. In seven well waters, it was concluded that RCE values were over 2,5 me L-1 and these water were not suitable in the usage of irrigation. As a result of the evaluations in terms of the specific ions, it was determined that CL, B and NO3-N concentrations which were found in three, two and one wells respectively, could create damages in some crops. As a result of the evaluations in terms of salinity and SAR parameters, it was concluded that the usage of T5, T6, T8, T10, T13 and T14 well waters was undesirable and the usage of T9, T11, T12, T16, T17 and T21 well waters can be suggested by the provision of some special conditions (appropriate drainage conditions, appropriate plant selection, coarse textured soils).

Tourism industry is one of the primary sectors that contribute to economic growth of countries worldwide. Since it requires appropriate weather conditions and clean environment, climate changes can significantly affect the sector. Therefore, this study examines the causality and long-run relationship between the climate change and tourism sector in Turkey. To estimate the potential long-run relationship between variables, Granger-Causality test is applied to data from 1960 to 2016. The study uses World Development Indicator Data released by World Bank. For the analysis, carbon-dioxide emission, methane emission, energy use (oil equivalent), and forest land are standing for climate change indicators. International tourist arrivals and tourism revenues represent for tourism sector’s variables. The findings show that there is a negative and significant coefficient of climate change on tourism sector. Also, in average, climatic change indicators have unidirectional and negative impact on international tourism revenue. Another finding is that climate change deteriorates to environment by augmenting carbon dioxide emission and methane emission. As a result, climatic change can weaken the tourism industry which can decrease the speed of Turkey’s economic development. In the long run, this research can pioneer assessing the economic and environmental impacts of climate change in the tourism sector bases.

Colour is an essential parameter at product quality control stages, and finally, it is necessary for the consumer marketing decision. It is possible to damage the products during the process from collection to storage. Also, it is a well-known condition, cold environmental conditions protect fruits from deformations negative effects, but most of the time, most of the consumers keep the fruits at room temperature in open packs during the consumption process. Also, this condition affects the product storage time. In this study, it is aimed that to determine the behaviours of the fruits in room temperature and humidity conditions. For this aim the colour change of the damaged pears were determined, in another term, colour change value from red to green and yellow to blue at the damaged pears were determined with lightness values by using image analysis technique and analysed with data mining methods. For this purpose, 100 “Akça” pear and 100 “Deveci” local pear cultivar used for experiments. Fruits were equally damaged by using a pendulum mechanism. The damaged fruits were kept at room temperature. Colour change areas on fruits were evaluated with X-rite Ci60 spectrophotometer, and the hardness of fruits was measured by using a fruit penetrometer. The colour (L, a, b) and ΔE values were analysed for the fruit cultivars. The relationship between fruit hardness and colour change were also demonstrated. The predictions were done supervised machine learning algorithms (Decision Tree and Neural Networks with Meta-Learning Techniques; Majority Voting and Random Forest) by using KNIME Analytics software. The classifier performance (accuracy, error, F-Measure, Cohen's Kappa, recall, precision, true positive (TP), false positive (FP), true negative (TN), false negative (FN) values were given at the conclusion section of the research. The best prediction were found at the Majority Voting method (MAVL) 98.458 % success given with 70% partitioning.

In turkey, one of the most important problem of livestock’s production is insufficiency of quality forage crop, but still few forage species are cultivated. On the other hand, conservation of plant genetic resources has become an important problem in the world today. Indeed, biodiversity is an indispensable element of human life, especially food, and it is estimated that 20% of these resources will extinct by 2030. The aim of study was to determine some quality traits of white sweet clover (Melilotus alba Desr.) collected from natural flora of Bilecik province. In this study, plants were collected at the flowering stage and investigated of 17 genotypes. The determined quality traits of genotypes as fallows; crude protein, ADF, NDF, RFV, K, P, Mg, Ca and Ca/P, and these traits were noted as11.99-21.07%, 27.70-40.53%, 43.31-55.84%, 93.44-147.02, 1.300-2.807%, 0.187-0.310%, 0.127-0.350%, 0.490-1.417% and 2.05-5.92%, respectively. As a result of the study, it has been determined that the quality of the white sweet clover genotypes collected from Bilecik natural flora have been sufficient for animal feeding and have a significant potential for future breeding activities.

Mohamed Ghellam | Ilkay Koca
It is very important to develop a new way of treatment for foodstuffs to provide consumers more chances to choose their foods. In the present study, we aimed to investigate the effect of microwave drying conditions on the rehydration process of Algerian truffles. Previously dried truffles, at different microwave power output (350, 500 and 650 Watt) and weights (100 and 150 g) have been utilized to analyses and to model the rehydration kinetics. Among the six used empirical models, Weibull model has been the most fitted model to all the treated samples. Microwave power output and sample weight were found to have an effect on truffles during drying, and consequently on their rehydration capacity. The high samples amount has decreased the effects of microwave drying by decreasing the density of treatment, also, the high-power output has probably reduced the time of evaporation, and thus more preservation to the dried truffles. These results can be taken into consideration for more industrial applications of microwave drying and subsequent rehydration of truffles.

Pneumonic Pasteurellosis (PP) is an infectious disease caused by Pasteurella multocida and Mannheimia haemolytica, mostly observed in cattle, sheep and calves. PP is characterized by fibrinous bronchopneumonia and pleuritis in the lungs. In this study, it was aimed to determine Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase expressions by immunohistochemical methods in the lungs suffered from PP. For this purpose, twenty lung tissues were collected from calves with PP. For the Control Group, ten lungs of calves were collected from Aksaray Slaughterhouse. After necropsies of calves were confirmed to be PP by bacteriological examinations. Then the routine histological process was performed to tissues, and stained by Hematoxylin & Eosin for histopathology, and Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase antibody staining for immunohistochemistry. The immunohistochemical findings indicated that Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase positive reactions were seen in alveolar, bronchial and bronchiolar epithelia, and desquamated inflammatory cells in the lumens. In addition, the peripheral neural extensions were immunopositive for neuronal nitric oxide synthase and vascular endothelial cell were positive for inducible nitric oxide synthase. The findings can contribute to a better understanding of expressions of molecules such as Caspase and nitric oxide synthase. These results show that apoptosis and nitric oxide synthase expressions have triggered by airway epithelia and inflammatory cells in the lungs with Pneumonic Pasteurellosis in calves.

Araştırma, Çukurova Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama Çiftliğinde bulunan Rio Red altıntop ağaçları kullanılarak 2011 ve 2012 yıllarında yürütülmüştür. Çalışmada, deneme bahçesindeki mevcut sulama proğramının değerlendirilmesi ile ağaçlara farklı düzeylerde uygulanan sulama suyu miktarının, verim ile meyve kalite özellikleri (pomoloji) üzerine etkilerinin belirlenmesi amaçlanmıştır. Denemede damla sulama sistemi ile 3 farklı miktarda sulama suyu uygulanmıştır (I100); (I70); (I50). Her iki yıl dikkate alındığında sulama suyu miktarları, 332,48 mm (I100) ile 128,69 mm (I50) arasında değişmiştir. Gerçek bitki su tüketimleri ise su bütçesi yöntemine göre 935,6 mm (I100) ile 729,9 mm (I50) arasında gerçekleşmiştir. Denemenin birinci yılında, sulama konularına ilişkin verimler, ağaç başına, 306 (I70) ile 330 (I50) kg, ikinci yıl ise ağaç başına ortalama verim değerlerinin sulama konularına göre, 59,6 kg (I100) ile 108,5 kg (I50) arasında değişmiştir. Toplam su kullanma randımanları, 2011 yılında, WUEET 5,18 kg m-3ile 6,34 kg m-3, 2012 yılında ise; 0,52 kg m-3ile 1,74 kg m-3arasında elde edilmiştir. Sulama suyu kullanma randımanları, 2011 yılında, WUEI 15,85 kg m-3ile 30,69 kg m-3, 2012 yılında ise; 2,17 kg m-3ile 14,27 kg m-3değerleriarasında değişmiştir. Denemenin birinci yılında ortalama suda çözünen kuru madde miktarları, %10,22 (I100) ile %12,91 (I50) arasında; ikinci yılında ise %12,41 (I100) ile %13,47 (I50) arasında değişmiştir. Bu çalışma kapsamında sulama konularının meyve verimine etkilerinin istatistiksel olarak önemli olmamasından dolayı çifçilere su tasarrufu sağlamak amacıyla yöre için su kısıntısı önerilebilir.
