Demirbilek, Deniz; Önal, Ayten Oztufekci; Demir, Veysel; Uslu, Gulsad; Arslanoglu-Isik, Hilal
Environmental monitoring of leachate quality from an open municipal solid waste dumping site in Tunceli, Turkey was studied in this research. The most commonly examined pollution parameters were determined on a seasonal basis. The annual average 5-day biological oxygen demand (BOD5) and chemical oxygen demand (COD) values of station points were measured as 70 and 425 mg/L, respectively, and also the average BOD5/COD ratio (a measure of biodegradability) was calculated as 0.20. The low ratio of biodegradability and slightly alkaline pH values in the leachate samples indicated that the site was characterized by methanogenic conditions. The mean ammonium-nitrogen (NH4 (+)-N) and corresponding phosphate (orthophosphate) values were assayed as 70 and 11 mg/L, respectively. The average solids content in the leachates was measured as 4,681 mg/L (total solids) and 144 mg/L (suspended solids). Very low concentrations of iron, manganese, copper, and zinc in the leachate samples were found and the concentration of cadmium was measured below detection limits. Excessive amount of nutrients and high organic and inorganic pollutant content in the leachates pose serious pollution potential to the environment. Since no drainage system or bio treatment exists in this open dumping site, high permeability of natural soil at the site and in the surrounding area and very fractured and crackled rocks under natural soil are indicators of high groundwater pollution potential in this site.

Tuncer, Murat; Dogan, Yunus; Tanas, Ramazan; Isman, A; Siraj, S; Kiyici, M
Internet is shown among the main ways of learning in many recent research findings. Many masses like personnel and students prefer meeting their need for obtaining knowledge with internet above all. This positive impact of internet on learning can be better increased with the determination and direction of various psychological perceptions of the learners'. One of these psychological traits is attitude towards Internet. In this study, 265 undergraduate students', from various departments of Tunceli Vocational School of Tunceli University, attitudes towards internet were investigated. The Attitude Towards Internet Scale was used as the data collection instrument. The opinions gathered with the application of the scale were compared in terms of gender, grade, experience of computer education, age and field of study variables. Some of the findings are as following: the attitude towards internet does not differentiate meaningfully in terms of gender and grade variables; whereas there is a meaningful difference of opinions in terms of the field of study variable.

Yönten, Vahap
Exploring optimum and cost-efficient medium composition for microbial growth rate and lactose consumption of Kluyveromyces Lactis Y-8279 yeast culture growing on whey was studied by applying a multi-step response surface methodology (RSM). RSM is a combination of Plackett Burman (PB), Steepest-Ascent (SA) and Central Composite Design (CCD) Medium temperature, pH, yeast extract and lactose concentrations were evaluated the most effective operational factors through seven factors by applying PBD. These four factors were selected for SA program and SA experiments were carried out to find approximately maximum microbial concentration with lactose, pH, yeast extract and medium temperature. Then CCD was carried out with these factors (lactose, medium temperature, pH and yeast extract). Based on ANOVA test the optimum operational conditions of maximum growth rate were obtained as 18.8 g/L, 0.94 g/L, 5.2 and 27 degrees C, lactose concentration, yeast extract concentration, pH, and medium temperature, respectively. And then optimum operational conditions of lactose consumption were obtained as 13 g/L, 0.91 g/L, 8 and 27.5 degrees C, lactose concentration, yeast extract concentration, pH, and medium temperature, respectively too.

Gürkök, Tugba; Kaymak, Elif; Boztepe, Gulsen; Koyuncu, Mesut; Parmaksiz, Iskender
Papaver bracteatum Lindl., P orientate L., and P. pseudo-orientale (Fedde) Medw., species of section Oxytona Bernh. in the genus Papaver L., are found widely in the native flora of Turkey. They are commercially important for their high alkaloid content. Because genus Papaver section Oxytona has similar morphological characters, it is not easy to distinguish these species. We used the inter-simple sequence repeat (ISSR) molecular marker system to determine the molecular characterisation of this section. In this study, 20 ISSR primers have been studied in 180 accessions collected from 5 different regions of Turkey. A total of 82 bands were obtained, of which 80 were polymorphic. Average genetic distance was found to be 0.35, the Shannon index was 0.50, and the polymorphism rate was 96.97%. The primer AT10 had the smallest number of bands, which was 3, while the primers AT19 and AT3 had the greatest number of bands, which was 5. In conclusion, the ISSR marker system can be used for the classification of section Oxytona.

Can, Erkan
Intensive production can reduce production costs and improve efficiency of larvae culture. This study compared the effects of intensive and semi-intensive production on growth, survival, and V-shaped skeletal deformities in juvenile gilthead sea bream (Sparus aurata). At the end of the 50-day study, survival was 68.01 +/- 0.8%, mean weight was 1.32 +/- 0.03 g, and lordosis was 32% among juveniles raised in the intensive system. Survival and mean weight were significantly higher, 92.06 +/- 1.1% and 1.61 +/- 0.02 g, respectively, among juveniles raised in the semi-intensive system, and none had lordosis (p<0.05). Results suggest that semi-intensive systems are more advantageous than intensive for rearing sea bream juveniles.

The aim of study was to compare the effects of supplementation of food with herbal oils (Thymus vulgaris and Foeniculum vulgare) on biochemical properties and electrolytes of rainbow trout infected with Yersinia ruckeri. In total, 120 healthy fish (mean weight 84 +/- 1.02 g) were equally divided into four experimental groups. The experimental study was carried out for one week. The first group was control without supplementation and infection, the second group was infected and without oil supplementation, the third group was supplemented with oils (10 ml.100 g(-1) rates) for one week and infected with Y ruckeri and the last group was oil supplemented without infection. Results indicated that fish fed with dietary supplements showed enhanced bactericidal activity, total protein, albumin, cholesterol, triglyceride and bilirubin compared to the control (P < 0.05). As the value of herbal oils was increased in diets, the plasma glucose level decreased. The levels of K, Na, Ca, and Mg increased whereas Cl values decreased, compared to the control. It can be concluded that diet supplementation with herb oils used in this study can increase disease resistance by increasing levels of some biochemical parameters and electrolytes in rainbow trout to Y ruckeri infection.

The objective of the present work was to evaluate the effects of three different rates of long chain n-3 polyunsaturated fatty acid (LC n-3 PUFA) on the sperm number of Astacus leptodactylus. The experiment was carried out with the four following treatments: control group (not supplemented LC n-3 PUFA), D1 (1 %), D2 (2 %) and D3 (3 %). The sperm number of A. leptodactylus was counted; the reproductive system was weighted; and the macroscopical analysis of the testes and vasa deferentia (DVD) were conducted. In addition, gonado-somatic index (GI) and testes index (TI) were also calculated. The results showed that there was a significant difference between the crayfish fed LC n-3 PUFA supplemented diets (D1, D2, D3) and control in mean sperm number (P < 0.05). The highest sperm number was found for the crayfish fed D3 (6.27 +/- A 0.14 x 10(8) sperm/distal vas deferens section). The results also showed that the reproductive system of the crayfish fed D3 and D2 was significantly heavier than that of the crayfish fed the control and D1 (P < 0.05). On the other hand, there was not a significant difference in the testes weight and vasa deferentia weight between the crayfish fed the control and D1, and between the crayfish fed D2 and D3 (P < 0.05). GI of the crayfish fed D3 and D2 was significantly higher than that of the crayfish fed control and D1 (P > 0.05), but there was not a significant difference in the TI of the crayfish fed control, D1, D2 and D3 (P > 0.05). In conclusion, diets containing different levels of LC n-3 PUFA significantly increase the sperm number of A. leptodactylus, and they are crucial for the production of higher number of sperm in this species.

The objective of the present study was to obtain data about cooking time and temperature of kiymali pide in the restaurants and to investigate thermal inactivation of E. coli O157:H7 during experimental kiymali pide making. A field study was conducted in randomly selected 23 of 87 pide restaurants. Processing parameters including oven temperature, cooking period and post-cooking temperature were determined. Kiymali pide samples were prepared using ground beef filling experimentally inoculated with E. coli O157:H7 (7.6 log(10) CFU/g). Pide samples were cooked at a conventional oven at 180 degrees C for 180, 240, 270, 300 and 330 s. Results of the current study suggest that cooking kiymali pide at 180 degrees C for at least 330 s (5.5 min) may provide sufficient food safety assurance (>= 6 log(10) CFU/g) for E. coli O157:H7.

Dikici, Abdullah; Ilhak, Osman Irfan; Çalicioglu, Mehmet
This study was undertaken to evaluate the effects of some essential oil compounds for the inactivation of Listeria monocytogenes and Escherichia coli O157:H7 in cig kofte. In experiment 1, a cig kofte batch was inoculated with high levels of E. coli O157: H7 or L. monocytogenes (7.00 log(10) cfu/g) and the batches were divided into 6 groups. Each group was treated with 18 mL/kg of normal saline, cineole, limonene, carvone, linalool, or eugenol. Treatment with carvone, linalool, and eugenol resulted in a significant (P < 0.05) decrease in the numbers of both pathogens. In experiment 2, the cig kofte was inoculated with the same pathogens and each group was treated with 0 (control), 20, 22.5, and 25 mL/kg of eugenol. Increases in concentration did not cause a difference in pathogen reduction. The results showed that eugenol, carvone, and linalool can be used for the inactivation of E. coli O157: H7 and L. monocytogenes in cig kofte or similar foods.

Batu, Ali; Sen, Levent
Undamaged potato tubers (cv. 'Marfona') grown in Tokat, Turkey, were used in this study. The tubers were cured for two weeks at 15 degrees C and 75-85% relative humidity. The tubers were sorted for size, shape and physical damage and were divided into two groups. One group was left unwrapped and the other was placed on polystyrene trays and heat-sealed in 30, 40 or 60 mu m low density polyethylene (LDPE) film or 38 mu m c-polypropylene (CPP) film. The samples were kept in temperature-controlled rooms at 5 +/- 1 degrees C and 75-85% RH for eight months. Samples were taken every month during storage, and the internal colour, ascorbic acid, titratable acidity, pH and total soluble solids were determined. Results indicate that the harvesting time and storage period significantly affected quality parameters. The highest increases in total soluble solids, minimum change in pH, lowest titratable acidity and ascorbic acid values were found in tubers in 38 mu m CPP harvested on July 25th. The lowest pH and ascorbic acids were found in the 40 mu m LDPE packaged tubers, while maximum titratable acidity was found in the unwrapped tubers harvested on 20th September. The L* values indicate that the internal lightness of the tubers generally decreased during the storage period, indicating that they became a bit darker during storage.

The objective of this study was to determine the effects of different feeding protocols on compensatory growth, feeding rate, and feed conversion efficiency of Black Sea Trout Salmo trutta labrax. To our knowledge, no previous feeding experiments with Black Sea Trout have incorporated a fasting period to simulate the handling and acclimation conditions experienced by farmed fish. Fifteen fish per tank (10.69 +/- 0.06cm and 13.22 +/- 0.14g, mean +/- SE) were stocked into 40-L fiberglass tanks. Fish were fed with different fasting-feeding regimes for 95 d and were equally allotted to four treatments (T-cont: control; T5-10: 5 d fasting, 10days feeding; T10-10: 10 d fasting, 10 d feeding; and T15-10: 15 d fasting, 10 d feeding) with three replicates per treatment. The results indicated that length (P = 0.0005), weight (P = 0.000), condition factor (P = 0.013), and specific growth rate (P = 0.014) were significantly affected by the interaction between feeding and time. All fasting treatments showed partial compensation during refeeding. There was an increase in daily feeding rate and feed conversion efficiency in fasting treatments compared with the control treatment. In contrast, at the end of the experiment specific growth rate, condition factor, and body weight in fasting treatments were significantly lower compared with the control treatment. We concluded that there was partial compensation of growth with regular refeeding after periods of feed deprivation (e.g., 5, 10, or 15 d) over a long term and a shorter fasting period may be preferred in order to achieve compensatory growth.
