Eristi, Huseyin; Tümen, Vedat; Yildirim, Ozal; Eristi, Belkis; Demir, Yakup
In this paper, an effective classification approach to classify harmonic data has been proposed. In the proposed classifier approach, harmonic data obtained through a 3-phase system have been classified by using k-means and least square support vector machine (LS-SVM) models. In order to obtain class details regarding harmonic data, a k-means clustering algorithm has been applied to these data first. The training of the LS-SVM model has been realized with the class details obtained through the k-means algorithm. To increase the efficiency of the LS-SVM model, the regularization and kernel parameters of this model have been determined with a grid search method and the training phase has been realized. Backpropagation neural network and J48 decision tree classifiers have been applied to the same data and results have been obtained for the purpose of comparing the performance of the LS-SVM model. The real data obtained from the output of distribution system have been used to assess the performance of the proposed classifier system. The obtained results and comparisons suggest that the proposed classifier system approach is quite efficient at classifying harmonic data.

Eroglu, Ali; Dogan, Mahmut; Toker, Omer Said; Yilmaz, Mustafa Tahsin
Principal component analysis and hierarchical cluster analysis were applied to investigate physicochemical and instrumental textural properties of fresh kashar cheese. Four different principal components sufficiently explained the variability in the cheese samples. In addition, hierarchical cluster analysis was performed to group the kashar cheese samples regarding physicochemical and instrumental textural properties. Instrumental textural properties indicated greater variability than chemical composition of cheese samples. Principal component analysis revealed that color parameters were positively correlated with textural and chemical parameters. The results of this study revealed that other parameters rather than chemical composition would be effective on the instrumental textural properties. It was proved that principal component analysis was a very effective statistical tool to determine quality of cheese samples. According to the principal component analysis and hierarchical cluster analysis results, the attributes defining the kashar cheese samples were determined to be primarily the texture profile analysis parameters.

The antioxidant activities of methanol (ME), ethanol (EE), water (WE) and ethyl acetate (EAE) extracts of four Inula helenium L. taxa (I. helenium ssp. orygalis (Boiss.) Grierson, I. helenium ssp. pseudohelenium Grierson, I. helenium ssp. turcarasemosa Grierson and I. helenium ssp. vanensis Grierson) were investigated. The phosphomolybdenum assay, beta-carotene linoleate bleaching and DPPH radical scavenging activity were used to evaluate the antioxidant capacity. The total phenolic contents determined by Folin-Ciocalteu assay of the extracts ranged from 4.18 to 102.91 mg gallic acid equivalents (GAE)/g dry extract. The extracts showed considerable effect on reducing the oxidation of beta-carotene. The highest radical scavenging activity was obtained for ME of I. helenium ssp. orygalis in DPPH assay. ME, EE and EAE of four Inula helenium taxa showed significant antibacterial activity against 13 bacteria tested. WEs had no inhibitory effect against bacteria tested except for I. helenium ssp. orygalis. EE of I. helenium ssp. orygalis was only effective against C. albicans.

Baskonus, Haci Mehmet; Bulut, Hasan
In this paper, a new computational algorithm called the Improved Bernoulli sub-equation function method has been proposed. This algorithm is based on the Bernoulli Sub-ODE method. Firstly, the nonlinear evaluation equations used for representing various physical phenomena are converted into ordinary differential equations by using various wave transformations. In this way, nonlinearity is preserved and represent nonlinear physical problems. The nonlinearity of physical problems together with the derivations is seen as the secret key to solve the general structure of problems. The proposed analytical schema, which is newly submitted to the literature, has been expressed comprehensively in this paper. The analytical solutions, application results, and comparisons are presented by plotting the two and three dimensional surfaces of analytical solutions obtained by using the methods proposed for some important nonlinear physical problems. Finally, a conclusion has been presented by mentioning the important discoveries in this study.

There is little information in the scientific literature about effect of in vitro exposure of fish spermatozoa to pesticides. In vitro effect of Lambda-cyhalothrin (La) on sperm quality and oxidative stress has not been fully explored yet. The effects of LCT, which is a synthetic pyrethroid insecticide, on quality and oxidative stress of spermatozoa were investigated in vitro due to extensively use to control a wide range of insect pests in agriculture, public health, and homes and gardens. To explore the potential in vitro toxicity of La, fish spermatozoa were incubated with different concentrations of LCT (0.6, 1.2 and 2.4 mu g/L) for 2 h. Reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) in spermatozoa were analyzed for determination of oxidant and antioxidant balance. Our results indicated that the percentage and duration of sperm motility significantly decreased with exposure to LCT. Activity of GSH-Px and MDA (P < 0.05) and GSH levels (P < 0.05) increased in a concentration-dependent manner while CAT activity decreased (P < 0.05). In conclusion, the oxidant and antioxidant status and sperm quality were affected by increasing concentrations of LCT. (C) 2015 Elsevier B.V. All rights reserved.

The effects of alpha-iron oxide (alpha-Fe2O3) and gamma-iron oxide (gamma-Fe2O3) nanoparticles (NPs) on marine microalgae species (Nannochloropsis sp. and Isochrysis sp.) were investigated in this study. Both Fe2O3 NPs covered the surface of algae with the agglomerates of the nanoparticles. This form of physical NP toxicity significantly decreased the sizes of phytoplankton. Both NPs were toxic to the tested algal species, while alpha-Fe2O3 showed less toxicity than gamma-Fe2O3 NPs for both algal species. A comparative analysis of growth data of the two algal species treated with alpha-Fe2O3 or gamma-Fe2O3 NPs revealed that Isochrysis sp. are more sensitive than Nannochloropsis sp. Toxicity of these widely used NPs to primary producers forming the base of the food chain in aquatic environments might result in widespread adverse effects on aquatic environmental health.

Adiguzel, Ragip; Gunduz, Bayram; Turan, Nevin; Topcu, Yildiray
We investigated the optical properties and the transmittance characterizations of the stock solutions of the Co (II) and Ni(II) complexes of Saccharin and determined the molar extinction coefficients at different molarity. The molar extinction coefficients (epsilon) values of the Co(II) and Ni(II) complexes in the first region decrease with increasing molarity, and the e values of the Co(II) and Ni(II) complexes at lower wavelength are higher than that of the values at higher wavelength. The absorption band edge values of the Co(II) complex shift from 3.584 to 3.139 eV with the increasing molarity, while the absorption band edge values of the Ni(II) complex shift from 3.574 to 3.493 eV with the increasing molarity. The plots of refractive index of the Co(II) and Ni(II) complexes consist of two anomalous (abnormal) dispersion regions and one normal dispersion region. The direct energy-gap of the Co(II) complex can be more decreased with molarity. The absorbance, molar extinction coefficients, refractive index values of the Co(II) and Ni(II) complexes decrease, while the average transmittance in the visible region, direct optical band-gap values of the Co(II) and Ni(II) complexes increase with increasing volume of DMF solvent or decreasing volume of the solutions of the Coal) and Ni(II) complexes.

Polat, Ridvan; Cakilcioglu, Ugur; Kaltalioglu, Kaan; Ulusan, Musa Denizhan; Turkmen, Zafer
Ethnopharmacological relevance: This paper provides significant ethnobotanical information on medicinal plants in Espiye in the Black Sea Region. Recording such data calls for urgency. This is the first ethnobotanical study in which statistical calculations about plants are carried out by means of FIC method in Northern (Espiye-Giresun) part of Turkey. This study aims to identify the wild plants collected for medicinal purposes by locals of Espiye which is located in the Black Sea Region of Turkey, and to identify the uses and local names of these wild plants. Materials and methods: A field study had been carried out for a period of approximately 2 years (20122014). During this period, information about medicinal use of 55 wild and 15 cultivated plants were collected. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. Through face-to-face interviews, we identified and recorded demographic characteristics of the respondents. We interviewed 128 persons who are over the age of 29. The plant taxa were collected within the scope of the study; and herbarium materials were prepared. In addition, the relative significance value of the taxa was determined, and informant consensus factor (FIC) was calculated for the medicinal plants included in the study. Results: We have found out in the literature review of the plants included in our study that 70 plant taxa are already used for medicinal purposes while 3 plants are not available among the records in the literature. The most common families are Asteraceae, Rosaceae, Lamiaceae, Malvaceae, and Ericaceae. We include in our study and report for the first time the medicinal uses of Alchemilla crinita Buser, Stachys sylvatica L., and Thymus leucotrichus Hal. var. leucotrichus Hal. Names of local plants in Turkey vary especially due to vernaculars. The plants that the locals of Espiye use are called with the same or different local names in various parts of Anatolia. Conclusion: We found out that locals living in the research area use for therapeutic purpose 70 plants taxa which belong to 36 families. Turkish citizens with different ethnic backgrounds took the questionnaire. These people use these wild plants in treatment of several diseases. Comparison of the data obtained in this study with the experimental data obtained in the previous laboratory studies on the wild plants which grow in Espiye proved ethnobotanical usages to a great extent. Literature review indicated that the therapeutic plants that grow in Espiye are used in different parts of the world for the treatment of similar diseases. (C) 2015 Elsevier Ireland Ltd.

Ates, Mehmet; Arslan, Zikri; Demir, Veysel; Daniels, James; Farah, Ibrahim O.
Dietary and waterborne exposure to copper oxide (CuO) and zinc oxide (ZnO) nanoparticles (NPs) was conducted using a simplified model of an aquatic food chain consisting of zooplankton (Artemia salina) and goldfish (Carassius auratus) to determine bioaccumulation, toxic effects, and particle transport through trophic levels. Artemia contaminated with NPs were used as food in dietary exposure. Fish were exposed to suspensions of the NPs in waterborne exposure. ICP-MS analysis showed that accumulation primarily occurred in the intestine, followed by the gills and liver. Dietary uptake was lower, but was found to be a potential pathway for transport of NPs to higher organisms. Waterborne exposure resulted in about a 10-fold higher accumulation in the intestine. The heart, brain, and muscle tissue had no significant Cu or Zn. However, concentrations in muscle increased with NP concentration, which was ascribed to bioaccumulation of Cu and Zn released from NPs. Free Cu concentration in the medium was always higher than that of Zn, indicating CuO NPs dissolved more readily. ZnO NPs were relatively benign, even in waterborne exposure (p0.05). In contrast, CuO NPs were toxic. Malondialdehyde levels in the liver and gills increased substantially (p<0.05). Despite lower Cu accumulation, the liver exhibited significant oxidative stress, which could be from chronic exposure to Cu ions. (c) 2014 Wiley Periodicals, Inc. Environ Toxicol 30: 119-128, 2015.

Dikici, Abdullah; Koluman, Ahmet; Calicioglu, Mehmet
The aim of the present study was to investigate the effect of lactic acid against Shiga toxin producing Escherichia coli (O157:1-17 and non-O157 serogroups including O103, O111, O145 and O26) at different conditions. Soybean sprouts and spinach leaves inoculated with each serogroup of E. coli (similar to 7.00 + 1.00 log(10) cfu/g) were treated with the lactic acid solutions at different concentrations (0% (control), 1.5%, 2.0%, or 2.5%) and at different temperatures (20, 40, or 50 degrees C) for 3 min. Results indicated that regardless of the treatment temperature, no significant reduction in the numbers of any serogroup occurred in the control group (0%) (p > 0.05). However, lactic acid at concentration of 1.5%, 2% and 2.5% was found to be effective against all organisms tested. There was no significant difference (p > 0.05) between E. coli O157:H7 and non-O157 STEC serogroups at any treatment group. The highest reductions (ca. 400 log(10) cfu/g) of all serotypes in both produces were observed after immersing into 2.5% lactic acid at 50 degrees C. The results of this study showed that decontamination of fresh produces such as spinach and soybean sprout with lactic acid solutions prepared at mild temperatures (40 degrees C and 50 degrees C) might be an effective safety measure in preventing public health risks associated with these products contaminated with STEC.

In this study, Artemia salina (crustacean filter feeders) larvae were used as a test model to investigate the toxicity of aluminum oxide nanoparticles (Al2O3 NPs) on marine microorganisms. The uptake, toxicity, and elimination of -Al2O3 (50 nm and 3.5 m) and -Al2O3 (5 nm and 0.4 m) NPs were studied. Twenty-four and ninety-six hour exposures of different concentrations of Al2O3 NPs to Artemia larvae were conducted in a seawater medium. When suspended in water, Al2O3 NPs aggregated substantially with the sizes ranging from 6.3 nm to >0.3 mu m for spherical NPs and from 250 to 756 nm for rod-shaped NPs. The phase contrast microscope images showed that NPs deposited inside the guts as aggregates. Inductively coupled plasma mass spectrometry analysis showed that large particles (3.5 m -Al2O3) were not taken up by Artemia, whereas fine NPs (0.4 m -Al2O3) and ultra-fine NPs (5 nm -Al2O3 and 50 nm -Al2O3) accumulated substantially. Differences in toxicity were detected as changing with NP size and morphology. The malondialdehyde levels indicated that smaller -Al2O3 (5 nm) NPs were more toxic than larger -Al2O3 (0.4 mu m) particulates in 96 h. The highest mortality was measured as 34% in 96 h for -Al2O3 NPs (5 nm) at 100 mg/L (LC50 > 100 mg/L). -Al2O3 NPs were more toxic than -Al2O3 NPs at all conditions. (c) 2013 Wiley Periodicals, Inc.

AimThis study was planned to assess the levels of fatigue and social support in patients with diabetes and to determine the relationship between fatigue and social support in these patients. MethodsA descriptive design was used in this research. The study was conducted between March and June 2013 with 300 sampled patients from 1657 studied participants with type 2 diabetes who presented to the diabetes polyclinics of Malatya State Hospital and Inonu University, Turgut Ozal Medical Center. The Multidimensional Scale of Perceived Social Support and the Fatigue Severity Scale were used in the study. ResultsWhen the correlation analysis carried out between fatigue severity and social support in patients with diabetes was examined, a significant relationship was found in the negative direction between fatigue severity and family support (r=-0.145, P<0.05) as well as overall support (r=-0.132, P<0.05). A statistically significant difference was found between the Fatigue Severity Scale score and sex, education status, occupation, cohabitation, presence of complications, and hemoglobin A1c (P<0.05). Family support was significant only with respect to marital status, occupation, and being employed (P<0.05). ConclusionIt was seen at the end of this research that social support reduced the level of fatigue in a number of patients with type 2 diabetes. Nurses of diabetes patients should carry out fatigue assessments routinely and reflect these in nursing care plans by also associating them with the social support sources of the patient.

Demir, V.; Dere, T.; Ergin, S.; Cakir, Y.; Celik, F.
Tunceli, Turkey is one of the small cities in the Eastern Anatolian Region with substantial natural, cultural and historical heritage that is suitable to be a slow city. Water sources are abundant in the area due to rain and heavy snowfall in the mountains, which seeps into the ground or flows into the rivers. Therefore monitoring and conservation of city's drinking water quality is one of the main issues in the city. The present study was conducted to investigate several heavy metals and cyanide, arsenic, and selenium concentrations of drinking water samples taken from 100 different locations in the city and towns of Tunceli, Turkey during the years 2011 and 2012. In three locations, high levels of copper was found with a range of 2.1-11.5 mg/L, and high levels of arsenic was detected in five locations with a range of 10.5-78.0 mu g/L, exceeding the action levels for copper and arsenic. For health risk assessment, the average daily dose and hazard quotient (HQ) were calculated. The region mean values of HQ were found above 1 for arsenic in the samples collected from Mazgirt, while HQ values were below 1 in the rest of the samples.

Trichlorfon is among the most commonly used products to treat fish parasites in aquaculture. We investigated the effectiveness of propolis in alleviating the toxicity of trichlorfon on haematological and oxidant/antioxidant parameters in carp Cyprinus carpio. Fish were exposed to sublethal concentrations (11 and 22 mg l(-1)) of trichlorfon, and propolis (10 mg kg(-1) of fish weight) was simultaneously administered. At the end of 14 d administration, blood and tissue (liver, kidney, gill) samples were collected. Haematological changes (red and white blood cell count, haemoglobin concentration, haematocrit level and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration) were determined in the blood samples, while antioxidant parameters (malondialdehyde and reduced glutathione levels and superoxide dismutase, catalase and glutathione peroxidase activities) were evaluated in the liver, kidney and gill samples. Trichlorfon led to negative alterations in the haematological and antioxidant parameters investigated. The administration of propolis alleviated this effect and suggests that fish treated with trichlorfon improve their physiological status when fed a propolis-supplemented diet.

The main purpose of the present study was to investigate the effect of case-based instruction on remedying 10th grade students' alternative conceptions related to gas concepts. 128 tenth grade students from two high schools participated in this study. In each school, one of the classes was randomly assigned as the experimental group and the other class, instructed by the same chemistry teacher, was assigned as the control group. The students in the experimental groups were instructed by case-based instruction based on conceptual change conditions while the control group students received traditionally designed chemistry instruction. As pre-tests, the science process skills test, the attitude and motivation towards chemistry and the gas concept test were applied to both groups of students. As a post-test, the gas concept test was administered to both groups of students to determine their alternative conceptions and understanding of gas concepts. One-way ANOVA was used to assess the effect of case-based instruction on students' understanding of gas concepts. The results revealed that case-based instruction was an effective method for overcoming students' alternative conceptions about the gas concepts.

In this study, the effects of fat (10, 15 and 20%) and orange fiber (0, 2 and 4%) levels on volatile compounds of sucuk (Turkish dry-fermented sausage) were investigated. The volatile compound profile of sucuk samples was analyzed by gas chromatography/mass spectrometry (GC-MS) by using a solid phase microextraction (SPME). 75 volatile compounds were identified in the sucuk samples. The volatile compounds identified were 11 aldehydes, 7 aliphatic hydrocarbons, 2 acids, 10 esters, 1 furan, 5 alcohols, 8 aromatic hydrocarbons, 6 ketones, 6 sulphur compounds, and 19 terpenes. It was determined that the use of orange fiber had significant (P<0.05) effects on a few volatile compounds (allyl methyl sulfide, copaene and caryophyllene). Alpha-thujene was significantly affected by fat level (P<0.05). Fat level also showed very significant effect on p-xylene and allyl methyl sulfide (P<0.01). As result, orange fiber and fat level had no significant effects on volatile profile of sucuk samples.

Mutlu, Ekrem; Demir, Tugba; Kutlu, Bann
One of the pollutants leading to heavy metal pollution is the lead element. The studies on exposure of fish to lead have shown that this exposure leads to negative effects on body weight, and digestive enzymes and lipase. In humans, the symptoms of chronic lead toxicity are renal malfunction, anemia, brain and liver damage, cancer, hyperactivity, and general psychological impairment. For struggling with this heavy metal contamination, we have a useful tool named Zeolite. Zeolites are used in many fields such as agriculture, metal industry, energy sector, manufacturing industry, water treatment, animal husbandry, struggling with environmental pollution, and etc. In this study, we utilized the biochemical parameters of carp fish (Cyprinus carpio) in order to reveal the effects of zeolite on fish health and production. The experiments were performed within 100 L glass aquariums with 85x40x30 dimensions. The study was planned for 3 different durations as 35 days, 90 days, and 120 days. The subjects were divided into 4 groups for each of experiment durations. The groups were named Pb(NO3)(2) group, Pb(NO3)(2) + Zeolite group, Zeolite group, and control group. At the end of each of the experiment period (on 35(th), 90(th), and 120(th) days), the fish in groups were weighed, and the average growth rates of each of the groups were calculated. The parameters used in blood analyses are glucose (GLU), blood urea nitrogen (BUN), total protein (TP), albumin (ALB), globulin (GLB), creatinine (CR), total bilirubin (TBIL), uric acid ([JA), and direct bilirubin (DBlL).
