Kükrer, Serkan; Seker, Sebahat; Abaci, Z. Tugba; Kutlu, Banu
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.

Bayirli, Mehmet; Selvi, Selami; Cakilcioglu, Ugur
Fractal dimensions of leaves from Cercis canadensis L., Robinia pseudoacacia L., Amelanchier arborea (F. Michx.) Fernald, Prunus persica (L.) Batsch, Quercus alba L., Carpinus caroliniana Walter, Ficus carica L., Morus rubra L., Platanus orientalis L., and Ulmus rubra Muhl. were calculated. The values were then confirmed and compared by those obtained from box-counting method and the exponent values of density-density correlation function (first time in the literature). It is now proposed for the first time that there is a relationship between a fractal dimension of the leaf and a surface density of the image and was concluded that together with other measures, the fractal dimensions with surface density function could be used as a new approach to taxonomical study of plants.

Yildirim, M.; Polat, M.; Öksüztepe, E.; Omaç, Z.; Yakut, O.; Eren, H.; Kaya, M.; Kürüm, H.
Estimation of dimension parameters for an electrical machine has great importance before manufacturing. For this reason, analytical design should be performed in an optimum form. While motor analysis is accomplished by package programs, initial size parameters are intutivily provided and then various trials are examined to get optimum results. In this study, we are trying to find dimensional and electrical parameters generating mathematical equations in analytic approaches for In-Wheel Switched Reluctance Motor (IW-SRM), which will be employed by Electric Vehicle (EV). Therefore, optimum motor parameters for required speed and torque have been estimated by solving generated equations for in-wheel SRM with 18/12 poles via MATLAB. Using the parameters, analysis of in-wheel SRM has been carried out 3D Finite Element Method (FEM) by Ansoft Maxwell 15.0 Package Software. Consequently, the accuracy of the estimated parameters has been validated by the results of Maxwell 3D FEM.

Kutluyer, Filiz; Kayim, Murathan; Ögretmen, Fatih; Büyükleblebici, Serhat; Tuncer, P. Barbaros
In present study, it was examined whether addition of different antioxidants to the cryopreservation extenders had an effect on semen post-thaw fertility and motility in rainbow trout (Oncorhynchus mykiss) and also it was investigated the sperm characteristics post-thaw sperm characteristics and fertility. The collected semen was pooled to minimize individual variation. Each pooled ejaculate was split into 12 equal aliquots and diluted with base extenders supplemented with the antioxidants, and a base extender with no additives (control). The pooled semen samples diluted at the ratio of 1:10 by the extenders were subjected to cryopreservation. Antioxidants were separately added to the extenders (one per experimental group): catalase (250 U/l), superoxide dismutase (250 U/l), peroxidase (250 U/l), oxidized glutathione (1.5 mmol/l), reduced glutathione (1.5 mmol/l), L-methionine (1.5 mmol/l), uric acid (0.25 mmol/l), L-ascorbic acid (0.5 mmol/l), alpha-tocopherol (2.0 mmol/l), beta-carotene (0.5 mmol/l) and camitine (0.5 mmol/l). After dilution the semen was aspirated into 0.25 ml straws, the straws were placed on the tray, frozen for 10 min, and plunged into liquid nitrogen. Our results indicated that the post-thaw motility rate increased in extenders supplemented with uric acid, L-methionine, SOD, L-carnitine, alpha-tocopherol and L-reduced glutathione (p < 0.05). The motility duration of frozen thawed semen increased in extenders supplemented with uric acid, L-methionine, SOD, alpha-tocopherol and L-reduced glutathione (p < 0.05). Fertilization rate and hatching rate of frozen-thawed semen was not affected by the tested antioxidants. Consequently, the tested antioxidants affected the motility parameters and cryopreservation extenders could be supplement with antioxidants. This study suggested usage of antioxidants in the cryopreservation of rainbow trout. (C) 2014 Elsevier Inc. All rights reserved.

Ates, M.; Dugo, M. A.; Demir, V.; Arslan, Z.; Tchounwou, P. B.
Nanotechnologies research has become a significant priority worldwide. Many engineered nano-sized materials have been increasingly used in consumer products. But the adverse effects of these nanoparticles on the environment and organisms have recently drawn much attention. The present study investigated the effects of different concentrations of copper oxide nanoparticles (CuO NPs) on the sheepshead minnow (Cyprinodon variegatus) at different salinity regimes, since it is able to withstand a wide range of salinities. The results indicated that CuO NPs could cause behavioral changes in the fish, such as increased mucus secretion, less general activity and loss of equilibrium. No mortality was observed at the presence of CuO NPs during the experiments. But higher oxidative stress was determined at half strength seawater than seawater exposure medium, which can be associated with the decreasing toxicity of CuO NPs as salinity increases. In addition, Cu contents in the tissues of the fish were significantly higher (p<0.05) in the low salinity. The order of Cu accumulation in the fish's organs was intestine > gills > liver.

Crayfish (Astacus leptodactylus Eschscholtz, 1823) is the native crayfish species in Turkey. It was exported regularly to Western Europe. In this study, bioaccumulation and temporal trends of some trace elements (arsenic: As, cadmium: Cd, copper: Cu, mercury: Hg, lead: Pb, and zinc: Zn) in edible abdomenmuscle of crayfish from Keban Dam Lake (Elazig, Turkey) were investigated for the 2006-2012 period. Sequence of metal concentration levels was Zn > Cu > Hg > Pb > Cd > As in muscle tissues. The highest concentration of Zn (21.69mg kg(-1)) was detected in 2006, while the lowest (4.35mg kg(-1)) in 2009. In general, it was found that the concentrations of trace elements investigated were lower than the maximum permissible limits of the food regulations of the Ministry of Food, Agriculture, and Livestock (MFAL), the Turkish Food Codex and Commission Regulation (EC). If the crayfish selected for the study are recognized as bioindicators of environmental pollution, then it is possible to conclude that the changes in studied trace elements concentrations in the Keban Dam Lake are being steady.

Purpose: To evaluate the fatty acid composition of six Centaurea species, viz, Centaurea behen, C. saligna, C. depressa, C. urvillei subsp. urvillei, C. urvillei subsp. hayekiana and C. aggregata subsp. aggregata, from Elazig, Turkey. Methods: Fatty acid methyl esters (FAMEs) of the oil extracts of four Centaurea species were prepared. The fatty acid compositions of Centaurea species were analyzed by gas chromatography (GC). Results: Saturated fatty acids (SFAs) in Centaurea species and subspecies ranged from 24.61 - 50.92% of their total fatty acid content, while monounsaturated fatty acids (MUFAs) were in the range of 3.40 - 37.96% and polyunsaturated fatty acids (PUFAs) 12.21 - 20.57%. Palmitic acid C 16: 0, oleic acid C 18:1 omega 9 and linoleic acid C 18:1 omega 3 were the major fatty acids in all the species. Oleic acid was the main constituent of C. urvillei subps. urvillei and C. agrregata subsp. aggregata with a content of 26.92 and 50.92%, respectively. Conclusion: The oil extracted from Centaurea species is a good source of essential fatty acids.

The morphometric and meristic characters of 2 F-2 hybrid striped bass (M. chrysops female x M. saxatilis male x M. chrysops female x M. saxatilis male) from the family Moronidae are described. Two specimens were caught from Kemer Dam Lake. The body of the F-2 hybrid striped bass was elongated, moderately compressed, and scaly. Dorsal surface and sides were silver and black to olive-gray, and the abdomen was white in color. Four or 5 longitudinal broken stripes ran above the lateral line to the caudal fin. The stripes were less visible behind the pectoral fins and below the lateral line. The bodies of the F-2 specimens were deeper than 1/4 the fork length. The 2 dorsal fins were separated entirely. The first dorsal fin had 8-9 spines, and the second dorsal fin had a spine and 13-14 soft rays. The caudal fin was slightly forked. The anal fin had 3 spines with 12-14 soft rays. One tooth patch was present on the anterior of the tongue. According to our results, the fish were F-2 hybrid striped bass offspring of F-1 hybrid striped bass, which can reproduce naturally in Turkey. Morphological criteria showed that the F-2 hybrids tended to resemble white bass (M. chrysops).

Yakut, O.; Eren, H.; Kaya, M.; Oksuztepe, E.; Polat, M.; Omac, Z.; Kurum, H.; Celenk, M.
In this study, we aim to determine fault severity in an electric car that may be caused by yawing due to such disturbances as non-uniform road pavements, in-wheel bearing clearance, suspension system, driver under Influence of alcohol (DUI), and tire deformation. The major research contribution herein is to alert drivers about an unforeseen situation on steering wheel whether it refers to a severe fault or contemporary states. In a sense, the undertaken study serves as a state of the art driving assistant system operating under unsteady conditions. We determine the fault severity of the system via classifying it into specified confidence regions by estimating the deviation from a monotonous straight route for any unstable situation. In this way, the proposed system informs driver to gain an insight about the severity level of arising problematic scenario. In order to realize the classification of confidence regions, we initially obtain the overall dynamic model of the system. Then, disturbance functions with different amplitudes and frequencies are characterized and included in the dynamic system specification. Here, the confidence regions have been constructed as to respective fault severity level of the car through the system response. Trajectory of vehicle in dynamic driving conditions considering these perturbations and noises are interrelated through the Kalman filtering to predict deviations from the desired trajectory and the prediction error. In simulation scenarios, Dynamic Time Warping (DTW) is employed to obtain deviation from ground truth under different noise functions, and results are sketched graphically assigning rate of fault severity into specified confidence regions. Initially, we have modeled the proposed system considering an electric car although the idea can readily be generalized for all cars with four tires. Presently, fault severity with classified confidence regions has been investigated under a simple car model.

Aim: To assess the effect of baby oil on pruritus, sleep quality, and quality of life in hemodialysis (HD) patients. Methods: This pretest-post-test model with control groups study was conducted in HD units in two different provinces in eastern Turkey. The study group consisted of a total of 70 patients receiving HD treatment who met the inclusion criteria, 35 being in the intervention group and 35 in the control group. After the patients in both groups were informed about the study, they were administered a questionnaire, the Severity Scale, Visual Analog Scale, the Pittsburgh Sleep Quality Index, and the SF-36 Quality of Life Scale. Following the administration of baby oil to the patients in the intervention group three times a week for a period of 1 month, the same scales were repeated to explore their pruritic status, sleep quality, and quality of life. The same scales were repeated also for the patients in the control group 1 month later but without administering any baby oil. Results: When the Itch Severity Scale, Visual Analog Scale, Pittsburgh Sleep Quality Index, and SF-36 Quality of Life Physical and Mental Component scores of the patients in the control and intervention groups before and after the intervention were compared, the differences in the change were found to be statistically significant in favor of the intervention group (P < 0.05). Conclusion: It was found in this study that administration of baby oil had positive effects on itching, quality of life, and sleep quality in HD patients who had itching complaints.

Yüksel, F.; Alp, A.; Gündüz, F.; Çoban, M. Zulfu; Demirol, F.
Fish populations in smaller aquatic environments are affected by the fishing pressure at a much faster pace. Often, compensation of this effect either takes a long time or is not possible at all. For the purposes of establishing fishing regulations in these water environments, the removal method is able to provide results quickly and almost accurately. The Lake Hazar, which is the environment of our study, is 8,600 hectares in size, and is a natural lake where Capoeta umbla species is caught commercially using gill nets. In this study, stock size of Capoeta umbla in the Lake Hazar (Elazig) was estimated using removal method. In addition, the power of fishing and the status of fishing yield in the lake were evaluated. In our research, it was determined that seven commercial fishing boats caught 25,721 kg of fish in the lake in a fishing season. CPUE was calculated as 1.55 kg (kg/day/a gill net). As a result of the regression analysis, the amount of stock in the lake was the estimated to be 37,781 kg (+/- 14,001 kg). When cumulative catch was formulated as recommended by Ricker (1975), the population size was estimated to be 38,649 kg (+/- 15,007 kg). As a result of our study, the use of removal method was found to be appropriate for small reservoirs with reduced population density due to strong fishing pressure.
