Yönten, Vahap; Aktas, Nahit
Exploring optimum and cost-efficient medium composition for microbial growth of Candida intermedia Y-1981 yeast culture growing on whey was studied by applying a multistep response surface methodology. In the first step, Plackett-Burman (PB) design was utilized to determine the most significant fermentation medium factors on microbial growth. The medium temperature, sodium chloride and lactose concentrations were determined as the most important factors. Subsequently, the optimum combinations of the selected factors were explored by steepest ascent (SA) and central composite design (CCD). The optimum values for lactose and sodium chloride concentrations and medium temperature were found to be 18.4g/L, 0.161g/L, and 32.4 degrees C, respectively. Experiments carried out at the optimum conditions revealed a maximum specific growth rate of 0.090 1/hr; 42% of total lactose removal was achieved in 24h of fermentation time. The obtained results were finally verified with batch reactor experiments carried out under the optimum conditions evaluated.

Arikan, Duygu; Saban, Fatma; Bas, Nazan Gurarslan
Objective: This research is done with the aim of determining hospital and health care satisfaction levels of the parents with inpatient children. Methods: Research was carried out descriptively at a university hospital after necessary permissions were taken from institutions. Parents whose children would stay at hospital between April-June 2012 formed the structure of the research and without using any sampling method, 171 volunteer parents were included in research. In collecting data, PedsQL Health Care Satisfaction Scale and descriptive information forms were used. In the statistical evaluation of data percentage distributions, means, standard deviation, t-test, ANOVA, Kruskal Wallis, Mann Whitney U test and alpha coefficient were used. Results: It was determined that there is statistically important difference between communication and technical skill sub-dimensions (p<0,05). It was confirmed that the longer the child hospitalized, general satisfaction of the parents who cannot supply their own necessities (p<0,05), related to moderate technical skill and emotional requirement sub-dimensions decreases (p<0.05). Besides, lower emotional satisfaction subdimension scores for those who had no accommodation (p<0,05), decreased general satisfaction level of the parents who had another child at home (p<0,05). Also family participation and general satisfaction subdimension scores of the parents whose child incurred financial burden was relatively low (p<0,05). Conclusion: Parents were not satisfied with health care services they received. Accordingly, it is offered that the nurses should have a right to make decisions on the procedures related to families' inpatient children and let them be with their children during the procedures and give them information on the procedures that will be applied on the children.

Yonar, S. Mise; Yonar, M. E.; Yöntürk, Y.; Pala, A.
In this study, effect of ellagic acid on some haematological, immunological and antioxidant parameters in the blood and various tissues of rainbow trout (Oncorhynchus mykiss) were examined. Four groups of rainbow trout were fed experimental diets containing either no ellagic acid (control) or supplemented with ellagic acid at 50mg/kg diet (EA-50), 100mg/kg diet (EA-100) or 150mg/kg diet (EA-150) for 21days. Samples of the blood and tissue (liver, kidney and spleen) were collected at the end of the experiment and analysed for their haematological profile (the red blood cell count, the haemoglobin concentration and the haematocrit level), immune response (the white blood cell count, the oxidative radical production (NBT activity), the total plasma protein and total immunoglobulin level) and oxidant/antioxidant status (the malondialdehyde level, the superoxide dismutase, catalase and glutathione peroxidase activity as well as the reduced glutathione concentration). The findings of this study demonstrated that ellagic acid had a positive effect on the haematological parameters, the immune response and the antioxidant enzyme activities of the fish.

Kaya, Gulderen Kurt; Bastürk, Ozden
Chemical and organoleptic changes in sea bass (Dicentrarchus labrax) preserved at 4C for 200 days have been investigated in this study. To prepare the fish fillets for study, they were put, at a ratio of 1:1.5 (fish:marinade brine), for marination into the brine containing 11% salt and 3.5% acetic acid. After the maturation process, samples were divided into two groups and packed in sealed plastic containers as plain and sauced and preserved for 200 days. At both groups packed as plain and sauced, TVB-N, TBA, TMA-N and peroxide number values were at acceptable limits during the storage of 200 days. It can be determined that both of the groups were approved in organoleptic terms; however, the sea bass marinades packed as plain were better approved. Our study shows that sea bass marinades packed as plain and sauced can be stored for 200 days without any quality problems. Practical Applications As the processed products are easy to store and bring a large margin of profit and always ready for the market, developing new products will contribute greatly to the aquaculture processing sector. Marinade processing technology is one of the cheapest technologies in aquaculture products processing and preservation methods, and it is very important in that it enriches the taste of fish, adds flavor and provides a longer shelf life. In the Mediterranean countries, sea bass ranks first in saltwater aquaculture and is among the most important aquaculture products. However; making use of the fish, especially which could not be sold or are undersold in the yield period, with the help of alternative processing methods can contribute to producers, the fisheries processing sector and the national economy. It was determined that sea bass marinades packed as plain and sauced can be stored for 200 days and can still retain their quality.

Uzuncayir Dam Lake is one of the most important water bodies in Tunceli. It is polluted by domestic wastewaters together with natural contamination and pesticides, which have had cumulatively negative effects. This study analyzes the effects of pollution by using the fish species, Capoeta umbla as a sentinel species, with a biomarker approach. The approach comprehends a general biomarker of individual fish health, the condition factor and specific biomarkers of contaminant exposure such as glutathione S-transferase (GST) and cytochrome P450 1A1 (CYP1A1) and acetylcholinesterase (AChE) activity. The general water physico-chemical parameters were measured at each sampling sites during each fish-sampling period. Strong seasonal and locational variations were observed among selected markers. In conclusion, the multibiomarker approach used in the present study clearly revealed differences in the fish health among reference and potentially contaminated sites. The study shows that changes of biomarkers such as acetylcholinesterase, glutathione S-transferase and cytochrome P450 1A1 might be useful for the assessment of environmental contamination in the Uzuncayir Dam Lake (Tunceli, Turkey).

Yuksel, Fahrettin; Gunduz, Fatih; Demirol, Ferhat
A study was conducted to determine the selectivity of monofilament gillnets with mesh sizes of 50, 60, and 70 mm that are used in Keban Dam Lake for fishing Luciobarbus esocinus (Heckel, 1843). During the study, a total of 394 L. esocinus were caught. Selectivity parameters were estimated using the indirect estimation method developed by Holt (1963). Optimum selection lengths for L. esocinus were calculated to be 36.61, 43.94 and 51.26 cm for gillnets with mesh sizes of 50, 60, and 70 mm, respectively. Common selectivity factor was estimated to be 7.32, with standard deviation 4.58. Length at first maturity of female L. esocinus (50 cm) was compared to the optimum selection lengths of gillnets with mesh sizes of 50, 60, and 70 mm. Results indicate that gillnets with mesh size of 70 mm would be appropriate for harvesting L. esocinus in the Keban Dam Lake, as the optimum selection length (51.26 cm) is greater than length at first maturity.

Aydin, Handan
The electrical and optical properties of carbon nanotube and titanium dioxide nano-composites have been investigated. The carbon nanotubes were prepared by chemical vapor deposition. The diameters and lengths of the carbon nanotubes were respectively determined to be 20-30 nm and about 3-5 mu m by high resolution transmittance electron microscopy. The direct current electrical conductivity values sigma(dc) of the nanocomposites were found to be in the range of 5.96 x 10(-3)-0.47 S/cm. It was found that the electrical conductivity of nanocomposites increases with CNT content. The optical band gaps of the nanocomposites were determined by Kubelka-Munk theory based on the analysis of diffuse reflectance spectra. The band gap (E-g) values of the composites were decreased with increasing CNT contents. The obtained results indicate that the electrical and optical properties of TiO2 semiconductor metal oxide can be improved by incorporation of CNT content for electronic applications.

Ince, Muharrem
In this study, samples of clay, tea waste, astragalus plant, chestnut shell, and egg shell were used as low-cost and eco-friendly adsorbents for the adsorption of Ni(ID from aqueous solutions. The effect of various parameters such as pH, contact time, adsorbent dose, and final volume on the adsorption capacities of these natural adsorbents were investigated by batch experiments. The adsorption capacity for Ni(II) was found to be 19.4 mg g(-1), 5.4 mg g(-1) 1.3 mg g(-1), 5.6 mg g(-1), 72.0 mg g(-1) for clay, tea waste, astragalus plant, chestnut shell, and egg shell, respectively. Egg shell has maximum adsorption capacity at pH 12, 45-minute contact time, and 0.5 g adsorbent mass. Nickel-free and nickel-loaded adsorbents were characterized by FTIR spectroscopy, which evidenced the functional groups involved in nickel uptake. This work investigated the utilization of eco-friendly and low-cost adsorbents as an alternative natural adsorbent for Ni(II) ions.

This study was aimed to monitor water pullution of Uzuncayir Dam Lake using the changes of IL-6, IL1 beta and TNF-alpha levels in Capoeta umbla (Heckel, 1843) liver tissue at ten stations in March and September 2011. In this study C. umbla (Heckel, 1843) was used as the indicator organism. Tumor necrosis factor-alpha (TNF-alpha), interlekuin1 beta (IL-1 beta) and interleukin-6 (IL-6) levels were determined in samples of the liver tissue by ELISA kit. The lowest mean IL-1 beta levels were found at station 6. The mean IL-1 beta was reached its maximum level at station 2. The difference between the mean levels of IL-6 was found to be significant (p<0.05) amoung stations. The IL-6 levels were significantly increased in September at stations 1, 2, 7 and 8 (p<0.01) compared to the values in March. The mean levels of TNF-alpha were found to be significant (p<0.05) amoung stations. The TNF-alpha levels significantly decreased in September at stations 1 and 9 (p<0.01). TNF-alpha, IL-1 beta and IL-6 levels in C. umbla can be used as early diagnostic indicators against adverse environmental events and useful and reliable bioindicators in determining the pollution of the aquatic ecosystem.

Kurtbas, I.; Guelcimen, F.; Kiliçarslan, A.; Kaya, M.
This study experimentally investigates the effect of conical injector type swirl generator inserts on heat and exergy transfer in a uniform heat flux tube for turbulence regime. One hundred twenty watts of heat are applied by coiling a flexible silicone heater on the tube (copper pipe) with an inside diameter of 62mm and length of 1,200mm. The conical injector type swirl generator has a conical shape, which is similar to a funnel, with angle (alpha) of 30 degrees, 45 degrees, and 60 degrees. Circular holes are drilled on the conical injector type swirl generator as three different cross-sectional areas (A(h)). The total areas (A(t) =N.A(h)) of the holes on the conical injector type swirl generator equal each other. Because of this, the three different holes numbers (N) are produced. Flow directors having three different angles (beta=30 degrees, 60 degrees, and 90 degrees) to radial direction are attached to every one of the holes. This study is a typical example for decaying flow. Reynolds number (Re) was varied from 10,000 to 35,000, so the flow was considered as only a turbulent regime. All experiments were conducted with air accordingly; Prandtl number was approximately fixed at 0.71. The local and average heat transfer Nusselt number (Nu(h)) and exergy transfer Nusselt number (Nu(e)) are calculated and discussed in this article. It is found that the Nu(h) increases with an increase in Reynolds number, director angle (beta), and director diameter (d) but with a decrease in the conical injector type swirl generator angle (alpha). However, Nu(e) decreases depending on the same independent parameters.

In this paper, the heavy metal levels (Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg), organic carbon, and chlorophyll degradation products were studied to prove their ecological effects in Lake CA +/- ldA +/- r, where fossil fuels are used as an energy source in the studied area for most of the year, and domestic waste from settlements is discharged directly into the lake. Sediment samples were collected from six sites on the northern shore of CA +/- ldA +/- r Lake, Turkey in November 2012. Enrichment (EF) and contamination factor (CF) values were determined, and Pollution Load (PLI) and Potential Ecological Risk (PER) indices were calculated. Average concentrations of heavy metals in the sediments were, in descending order, Fe > Mn > Zn > Ni > Cr > Cu > Pb > As > Cd > Hg, respectively. According to mean values, the source of these elements may be considered natural due to lack of enrichment in Cu, Pb, Zn, Ni, and Cr in the sediment samples. Regarding enrichment of As, Cd, Mn, and Hg, the highest EF belongs to Hg. PLI and PER values indicate there are moderate ecological risk in the lake.

Sançar, Taylan; Akyüz, H. Serdar
The last century earthquakes produced more than 1000 km surface rupture on the North Anatolian Fault Zone (NAFZ), which is one of the most active deformation belts in the World. Paleoseismic data from different parts of the NAFZ exposes critical information about the earthquake history of the fault zone. To research paleoseismicity of the Ilipinar Segment and relationship between the segment and last century earthquakes, two paleoseismologic trench studies performed on the Yoncalik basin, where positioned at eastern section of the Ilipinar segment. We identified two paleo-earthquakes, which correspond to BC 8500-6150 and BC 5960-4300 time intervals in the Yoncalik-1 trench. On the other hand the analyses of stratigraphy and structural features of the Yoncalik-2 trench similarly yield two events, from which the older happened before BC 6325 and the younger was between BC 6325-2105. Despite of the wide range of these intervals, both trench results are coincide within their uncertainty limits. We interpret that events in both trenches reflects the same surface ruptures. By the joint analysis of both trenches, we conclude that the most recent and penultimate events should have occurred between BC 5960-4300 and BC 8500-6325, respectively. The results from paleoseismology of the Ilipinar Segment, which constitute the easternmost part of the NAFZ, indicate that the seismic behaviour of the segment is not in accord with the general characteristic of the NAFZ. The reasons behind the disparity are considered to be related with complex fault geometry in the vicinity of Karliova triple junction and partitioning of accumulated strain on these structures.
