Validation of The Weather Generator CLIGEN with Season Precipitation Data in Tokat Province
2019
Saniye Demir | İrfan Oğuz
In models that predict hydrologic, ecological and product-yield relationship, the climate interface file is widely used. Today, CLIGEN is the most widely used climate model. While this model is extensively used in many countries around the world, it is not used commonly in our country. In this study, daily data belonging to Tokat climate conditions were simulated with CLIGEN. Observed and simulated precipitation was classified as the wet/dry period. The performance of the CLIGEN climate model was evaluated in both wet and dry periods according to the seasons. The relationship between the obtained precipitation data was statistically determined by Kolmogorov-Smirnov and t-test. Tokat province is located in the arid and semi-arid climate zone. The performance of the model in predicting precipitation in all seasons during the dry period was found to be quite successful.

Genetic diversity assessment is the principle component for conservation and characterization of germplasm. Genetic diversity study of Afghan bread wheat genotypes is a first step to identify and to select high performance genotypes and distribute to wheat breeding programs. The main objective of this study is to investigate of genetic diversity in 35 Afghan bread wheat genotypes by using Simple Sequence Repeat (SSR) and Amplified Fragment Length Polymorphism (AFLP) markers. DNA extraction according to Cetyl Trimethyl Ammonium Bromide (CTAB) method was conducted and the total genomic DNA was isolated from each variety. Sixty-four SSR primer markers were used and eighteen EcoRI+(N)/MseI+(N) primer combinations with their primer sequences were used for selective polymerase chain reaction (PCR) amplification. Every SSR and AFLP fragment was scored as present (1) or absent (0) within all genotypes under study. Marker/ Value ratio of pairwise genetic distance between genotypes according to the SSRs data was from 0.508 to 0.691 with an average distance of 0.599. Relatively different grouping pattern in comparison to AFLP data observed through cluster analysis. Both types of molecular markers (AFLP and SSR) used in this research proved to be suitable for investigating genetic diversity in the genotypes of Afghan bread wheat, however, AFLP markers gave better view of genetically relationships among genotypes than the SSR markers. The grouping generated by AFLP data showed a special agreement with the origin regions of genotypes (Ariana-07 and Mazar-99 originating from the north of Afghanistan, Lalmi-03 and Kabul-02. Large number of DNA bands identified with AFLP markers might provide a better estimation of genetic similarity than those of SSR markers.

2019
Ece Söğüt
The increase of consumer demand for using natural products and reducing the use of non-compostable packaging materials have encouraged research on biodegradable polymers including natural components such as essential oils. Pomegranate seed oil (PSO) has active properties such as antimicrobial and antioxidant activities. The aim of this study was to prepare active polycaprolactone (PCL) films by using PSO. PCL films including PSO emulsions (5-30%), which were stabilized with nanocellulose (NC) particles, were prepared by casting method. The physical and active properties of PCL films were determined by means of water vapor permeability (WVP), mechanical properties, optical properties, release behaviour, and potential antimicrobial activity. The WVP values of PCL films was lower when incorporated with NC-stabilized PSO emulsions. The incorporation of PSO into PCL films in the form of NC-stabilized emulsions significantly reduced the transmittance and lightness values, which resulted in an increase in opacity. In the release tests, the slower release of PSO was observed for NC-stabilized films. The stabilization of PSO with NC showed to be less effective when high concentrations of oil (30%) were used. Film samples showed potential antimicrobial activity against Escherichia coli, and Listeria monocytogenes, however, a clear zone of inhibition around the film samples was not detected. Results also suggested that the antimicrobial effect was dependent on two important factors: the release behaviour of PSO through the film samples and, the direct interaction between PSO and microorganisms. These results showed that the combination PCL films and PSO stabilized with NC could be an interesting approach in active packaging technologies.

In this study, it was aimed to determine the effects of enteritis, pneumonia and omphalitis on oxidative/antioxidant balance in the calves. In total, 27 calves with neonatal disease and 10 healthy calves (control) were used. The sick calves were divided into 3 groups according to localization of infection, omphalitis (n = 10), pneumonia (n = 8) and enteritis (n = 9). Blood samples of the calves were taken from jugular vein for analysis. Blood in tubes without anticoagulant was centrifuged at 5000 rpm for 5 min following clotting, and the sera were removed and stored at -80°C until analyzed. Serum malondialdehyde and nitric oxide levels of all groups were significantly higher, while glutathione, glutathione peroxidase, catalase and superoxide dismutase levels were significantly lower compared to the control group. As a conclusion, diarrhea, pneumonia and omphalitis are caused by oxidative damage in the calves, and antioxidant treatment may be beneficial in the treatment of these diseases.

In the present study, it is aimed to determine the current state of the goat raising businesses operating in the city of Uşak and in its provinces, their problems and to come up with suggestions for solutions to these problems. In the current study, as the sampling of the study, 132 goat-raising businesses were selected by means of stratified random sampling method and they were administered a questionnaire consisted of 83 questions. The data obtained from the analysis of the questionnaires have revealed that high majority of the goat-raisers are elementary school graduates (86.4%) and they generally raise Hair goat (89.4%). Moreover, it has also been determined that for the mating of goats, male goats are brought into the herd in September and October and this mating process occurs in the form of free insemination, the age for female goats to be used as stock is 15-18 months old, additional feeding and synchronization are not generally practiced and weaning of baby goats occurs when they are 3-4 months old. Births are usually given in February-March and milking also starts in this period and lasts 6 months on average, the lactation milk yield is 60-80 liters, milking is performed once a day with hand and the produced milk is mostly used in cheese production. Moreover, in goat raising, transhumance is not a common practice and high majority of the breeders apply regular protective vaccines. As in many other regions, many problems such as high feed prices, the difficulty in finding a shepherd and price fluctuations force goat breeders to quit. For goat raising to be sustainable, technical and economic supports given to breeders should continue and improve. If the feed can be supplied with the internal resources of the businesses and if their products can be marketed directly without using intermediaries then some of the problems can be alleviated. Putting greater emphasis on this issue and developing incentive policies will make contributions to goat raising. As a result of the present study, it was concluded that developing goat raising businesses operating mostly as small-scale family businesses in the city of Uşak to large-scale businesses where intensive production is made by providing the necessary incentives and subsides is of great importance.

Nowadays, due to some reasons, soil quality deteriorates, soil organic matter decreases, and plant growth is adversely affected such as damaging agricultural practices, unconscious pesticide and fertilizer use. There is also treatment sludge among the methods that will contribute to the soil. Sewage sludge, the inevitable by-product of municipal and other wastewater treatment plant operations, is a key issue in many countries due to its increasing volume and the impacts associated with its disposal. This environmentally hazardous treatment sludge can be significantly reduced by anaerobic digestion. However, the resulting gas and the residues from anaerobic digestion process need to be treated or stabilized. The use of sewage sludge in agriculture will provide both soil nutrient elements and waste sludge can be disposed with this application. Definitely, it is possible to evaluate the treatment sludges in many different areas. After cleaning the sludge from contaminants, it can be used as a good compost or soil improvement material. In this study, agricultural applications with sewage sludge were investigated.
