Children's playgrounds which are safe and quiet environments that children can play there have started to become rare as a result of rapid urbanization. Because, the studies have shown that unplanned and distorted urban spaces affect children's behaviours, attitudes and reactions in a bad way. In this study, the availability of children's playgrounds in 22 districts of the city centre of Ordu was investigated. In this context, firstly, children's play areas were determined based on the neighbourhood scale and then area calculations were made and the amount of play area by per child between 0-14 years was calculated in each district. In the second stage, accessibility maps for children's playgrounds were obtained by determining the availability of the playgrounds at 200m distance. The results of this study showed that children's playgrounds are not balanced in the city, increased in some districts, in some cases they are not within reachability limits and can not meet their needs.

Bu çalışmanın amacı, Narince üzüm çeşidine (Vitis Vinifera L) üç farklı form (amonyum nitrat, amonyum sülfat, üre) ve 4 farklı dozda (kontrol, 5, 10 ve 15 kg/da N) azot uygulamalarının taze asma yaprak verimine olan etkisi araştırılmıştır. 2012 vejetasyon periyodunda kordon şeklinde terbiye edilmiş asmalar bir veya iki göz üzerinden (24 göz/asma) dekara 5000 göz olacak şekilde şarj edilmiştir. Azotun dört farklı dozu bölünmüş parseller deneme desenine göre 4 tekerrürlü olarak asmalara uygulanmıştır. Salamuralık genç asma yaprakları beş dönemde hasat edilmiş ve taze yaprak verimi (kg/da) belirlenmiştir. Hasat edilen yaprak örneklerinde gübre formlarının yaprak verimi üzerine etkisi istatistiki olarak önemli bulunmuştur. Taze asma yaprak verimi 312,4 kg/da (Kontrol) ile 437,1 kg/da (Amonyum nitrat 10 kg N/da) arasında değişmiştir. Azot dozları arttıkça asma yaprağı verimi de artmıştır. Azot uygulaması taze yaprak verimini yaklaşık %30 artırmıştır. Deneme sonuçlarına göre, en yüksek asma yaprağı verimi 10 kg N/da uygulamasından alınmıştır. Amonyum nitrat uygulamaları ile diğer gübre formlarından daha yüksek yaprak verimi elde edildiği ortaya çıkmıştır.

Identification and multiple antibiotic resistances of amphicillin, chloramphenicol, streptomycin and tetracycline resistant gram-negative bacteria that isolated microorganisms from Gölbaşı and Azaplı lakes (Adiyaman) were investigated in this study. Seasonally taken isolates of totally 386 bacteria in 10 different species from 7 genera were scanned against 16 antibiotics [gentamycin, imipenem, kanamycin, chloramphenicol, meropenem, nalidixic acid, nitrofurantoin, penicillin, cephalothin, cefazolin, cefpirome, ceftizoxime, cefuroxime, streptomycin, tetracycline and trimethoprim-sulphamethoxazole (Bioanalyse)] by using the disc diffusion method to determine the prevalence of multiple antibiotic resistance. Multiple antibiotic resistance of stations showed seasonal changes between 0.29 and 0.91. In generally, multiple antibiotic resistance in Golbasi and Azapli lakes were higher than the reference value and highest multiple antibiotic resistance values were obtained at summer season (3th period). When the obtained data are considered, high multiple antibiotic resistance poses a risk in terms of public health and for economically important animals.

High vacuum steam distillation, simultaneous distillation extraction, steam distillation, purge and trap methods are used for sample preparation in volatile component analysis. Since these methods are difficult and costly to implement, these methods have left their place to the solid phase microextraction technique. Extraction conditions such as extraction temperature, extraction time, sample volume and fiber type should be optimized in order to increase the efficiency of extraction in volatile component analysis with solid phase microextraction in foods. In the optimization of extraction conditions in volatile component analysis of foods, studies have been carried out to utilize the response surface method, which reduces the number of experiments and also examines the interaction effect of the independent variables. In this review, it is aimed to give information about current studies using response surface methodology in optimization of volatile compound analysis of foods using solid phase microextraction technique.

The results showed that the prevalence of E. coli O157 in food was 2%, and its prevalence increased in April and May.

Prices of agricultural products fluctuate depending upon several factors. In Turkey, potatoes are one of the main products for which price fluctuations are observed. This study was undertaken to determine the effect of the fluctuation in potato prices on producer incomes in Turkey. The Neyman Method was used to determine the sample size. The number of enterprises required to achieve a representative sample size was determined to be 56, with a 5% error margin and a 95% reliability limit. The way in which the potato cultivation area is affected by price was examined. The Koyck model was utilized for this purpose. By using Koyck analysis, average lag time was calculated to be approximately 1 year. This result indicates that the fluctuation in potato prices has quite a rapid effect on production. It was determined that producer income varies greatly depending on annual potato prices. The difference between estimated potato price and the actual price for the year 2012 resulted in an income loss of 11,198.6 $/ha. Some sustainable efforts such as production planning can be recommended to prevent these price fluctuations.

Pomegranate has been recently considered as a significant fruit for human health and demanded year-long apart from two-month standard harvest period. To extend market supply durations over longer periods, various methods and treatments should be applied to pomegranates to preserve quality parameters throughout different storage durations. The present study was conducted at cold storages of ÇOMÜ Agricultural Faculty to investigate the effects of 1-Methylcyclopropane (1-MCP) and MAP (LDPE, 20 mµ) treatments on quality attributes of ‘Hicaz’ pomegranate cultivar. Experimental materials were treated with two different doses (625 and 1250 ppb) of 1-MCP alone and combined with MAP (625 ppb + MAP and 1250 ppb + MAP) and stored at 3 different storage durations (40, 80 and 120 days). All fruits, including control group, were stored at 6.5-7.5°C temperature and 85-90% relative humidity. At the end of each storage period, fruits were subjected to weight loss (%), Total soluble solids (TSS) content (%), titratable total acidity (TTA) (%g), pH, grain color (a value), decay ratio (%) analyses and assessments were performed for these quality and biochemical characteristics. Both Doses of 1-MCP alone and combined with MAP treatments were found to be more efficient in decelerating the adverse effects on rotting, perishes and other quality parameters, however there were not significant differences between two doses of 1-MCP. Therefore, MAP or 625 ppb 1-MCP treatments alone or combined with MAP treatments can be recommended for better preservation of quality parameter throughout the storage of pomegranates.

Effects of two dietary levels of starch and crude protein on performance of dairy cow fed low roughage level (70:30 concentrate to roughage) were investigated. Twenty eight Holstein cows were randomly assigned to one of four dietary treatments in a 2 x 2 factorial arrangement. Factors were two dietary level of starch (14% and 22%) and crude protein (15% and 18%). Wheat straw was used as sole roughage source. The study was continued 6 weeks. Dry matter intake was not affected (P>0.05) by the dietary treatments in the study. Milk and protein yield (kg/d) were higher (P
