Ethem Akyol
This study was conducted to determine the better hygienic behaviour determination method that is used in controlling against bee diseases and pests. Total forty honeybee colonies (Apis mellifera anatoliaca) were used and they were randomly divided into two groups (each group consists of twenty colonies) in first year. Liquid nitrogen method was used in the first group' colonies and pin-killing (needling process) method was used in the second group’ colonies to determine the effectiveness of methods for hygienic behaviour. Average clearance rate was found as 66.25% and 78.10% in the first (Liquid nitrogen application) and the second (pin-killing) groups respectively. In the second year, forty colonies were divided into five equal groups and each group consisted eight colonies. The first group consisted of 9 frames bees in standard langstroot hive (10 frame capacity), the second group consisted of 5 frames bees in standard langstroot hive (10 frame capacity), the third group consisted of 5 frames bees in ruşet hive (5 frame capacity), the forth group’s consisted of 3 frames bees in ruşet hive (5 frame capacity) and the fifty group consisted of queen mating hive. The pin-killing (needling process) method, tested in first year, was used for all groups to determine the effectiveness of colony population and the size of hive. Average clearance rates of the first, second, third, forth and fifth groups were 70.54%, 58.38%, 70.63%, 54.96% and 58.21% respectively. The colonies that belonged to the pin-killing (needling) group showed a higher cleaning behaviour rate than the other colonies. The density of bees in hive had an important effect on the clearance rate of colonies. The colonies of group 1 and group 3, which had the more density of bees in per unit area, had the higher clearance rate than the other groups.

The study was carried out to estimate the temperature, light intensity, salinity, Dissolved O2 (DO), pH values and the biotic parameter chlorophyll- a in the water column related with the depth. Because, the physico-chemical parameters affect greatly both primary and secondary producers in marine life. For this purpose the physico-chemical properties were determined day and night for 40 meter depth during the eight days. The means were compared by using the analysis of variance method and Duncan’s Multiple Comparison Test. Also physico-chemical parameters were estimated by using the analysis of regression and correlation. The effect of temperature and salinity were found significant according to the result of the analysis of variance during the day. Also the similar results were found for the night. While the effect of the depth on the chloropyll-a a was significant in the night, the effect of the depth on the DO was not significant in the day and night. The correlations among the depth and the parameters were defined. It was found the negative correlation between the depth and the temperature and light intensity. Determination coefficient of the model for salinity was also found different for day time. The correlation values among the depth and the temperature, salinity and pH were found different for the night.

İsmail Durmuş | Serdar Kamanlı | Sezai Alkan
This study was conducted to determine the influence of eggshell thickness, albumen height, yolk height and haugh unit on hatching results. A total of 746 eggs, which were obtained and evaluated for egg quality parameters from 100 brown pure line hens of 42 weeks of age, were used. Eggs were collected from each hen for 12 days and individual incubation was carried out. Eggs were grouped based on quality parameters and evaluated accordingly. The findings suggested that hatchability, hatchability of fertile eggs, early, mid and late embryonic mortality did not differ in terms of haugh unit, albumen height, eggshell thickness and yolk height groups. However, early embryonic mortality was found different between the yolk height groups. No relationship was determined among albumen height, haugh unit, eggshell thickness and hatching results. There was no relation between yolk height and hatchability of fertile eggs, hatchability, mid and late embryonic mortalities but was a positive correlation with early embryonic mortality. The results of the present study demonstrate that egg quality parameters studied here had no influence on hatching results except that early embryonic mortality increased with the yolk height.

Erkan Karacabey | Gulcan Özkan | Latife Dalgıç | Saliha Onur Sermet
Aromatization of olive oil especially by spices and herbs has been widely used technique throughout the ages in Mediterranean diets. The present study was focused on aromatization of olive oil by rosemary (Rosmarinus officinalis L.). Aromatization process was optimized by response surface methodology as a function of malaxation’s conditions (temperature and time). According to authors’ best knowledge it was first time for examination of oil yield performance with antioxidant potential and pigments under effect of aromatization parameters. For all oil samples, values of the free acidity, peroxide, K232 and K270 as quality parameters fell within the ranges established for the highest quality category “extra virgin oil”. Oil yield (mL oil/kg olive paste) changed from 158 to 208 with respect to design parameters. Total phenolic content and free radical scavenging activity as antioxidant potential of olive oil samples were varied in the range of 182.44 – 348.65 mg gallic acid equivalent/kg oil and 28.91 – 88.75 % inhibition of 2,2-Diphenyl-1-picrylhydrazyl-(DPPH•), respectively. Total contents of carotenoid, chlorophyll and pheophytin a as pigments in oil samples were found to be in between 0.09 – 0.48 mg carotenoid/kg oil, 0.11 – 0.96 mg chlorophyll/kg oil, 0.15 – 4.44 mg pheo α/kg oil, respectively. The proposed models for yield, pigments and antioxidant potential responses were found to be good enough for successful prediction of experimental results. Total phenolics, carotenoids and free radical scavenging activity of aromatized olive oil and oil yield were maximized to gather and optimal conditions were determined as 25°C, 84 min, and 2 % (Rosemary/olive paste; w/w).

In this study, through the analyses of water samples taken from 9 stations on the brook between July 2012 and June 2013, we aimed to determine the monthly and seasonal changes in water quality parameters of Brook Kuruçay, to determine the water quality properties, to reveal the pollution problems, to determine the suitability level in terms of aquatic life and to classify the quality of water in accordance with Surface Water Quality Management Regulation’s Inland Surface Water Classes criteria. The study area is located southeast of the Hafik District of Sivas city and the altitude is 2608 m. The water samples were collected from 9 stations established on the brook, and some physicochemical parameters and heavy metal concentrations were analyzed in water samples. The cleaning and maintenance of all of the equipment, land-type measurement tools, and glass sampling containers to be used in sampling were made 1 day before sampling. Sampling tubes were immersed into 15 cm below the water surface for taking water samples. Heavy metal concentrations were determined in the Sivas Provincial Control Laboratory in the same day with sampling (within 5 hours). The total alkalinity, total hardness, ammonium nitrogen, nitrite, nitrate, ammonium azote, phosphate, sulfite, sulfate, chloride, sodium, potassium, suspended solid matter (SSM), chemical oxygen demand (COD), biological oxygen demand (BOD), calcium, magnesium, ferrous, lead, copper, zinc, nickel, mercury and cadmium analyses of water samples were performed. As a result of the analyses, it was determined that, since Brook Kuruçay falls into the water resource class, which is the most sensitive to pollution, the water quality of the brook should be monitored regularly.

Sinan Uzunlu | Işıl Var
Mantı, the traditional Turkish food, was subjected to modified atmosphere packaging (MAP) compositions of MAP 1 (80% CO2 + 20% N2), MAP 2 (40% CO2 + 60% N2), MAP 3 (60% CO2 + 40% N2) and control (packaged under atmospheric composition) to extend its refrigerated storage at 4°C. The physical, chemical and sensorial qualities of each package were assessed by analysing headspace gas composition, pH, water activity, 2-thiobarbituric acid (TBA), dry matter, lipid content and a sensory analysis of both cooked and raw mantı samples. The compositions of MAP samples (MAP 1, MAP 2 and MAP 3) resulted in the maximum storage time of 126 days versus 20 days in normal atmospheric packaging (control). In conclusion, 60% CO2 or either 80% CO2 with N2, as a make-up gas, should be implemented in the mantı process.

Arzu Seçer | Mustafa Boğa
In Turkey, there are 31.1 million head sheep in 2014. Central Anatolia Region has 8.3% of this total number. Nigde is the most important sheep producer province in this region. In this study it is aimed to determine marketing structure of products obtained from sheep production activities, define problems of it and present solutions for these problems. The main material of the research was consisted of primary data obtained from 39 Akkaraman sheep producers in Çamardı district in Nigde. In the sheep farms, milk production yield was 1374.4 kg per year. As 73.5% of this yield was presented to market, rest of it was used for self-consumption. Milk was generally sold to local traders. In the operations, livestock also was sold. When 89.7% of livestock sold to kasaps 10.3% of it was sold to local traders. It can be said that producers who are the members of cooperatives were very low and 51.3% of the producers stated that cooperatives can be useful for the solutions of marketing problems of sheep products. Main expectations of producers from cooperatives were providing them market alternative, providing easiness for processing of products and leading to increasing numbers and kinds of buyers in the market.
