Mükemre, Muzaffer; Behçet, Lutfi; Çakilcioglu, Ugur
This study aims to record accumulation of knowledge on plants which are used as food by native people of Catak (Van, Turkey) that has a rich culture and a very natural environment. In addition, the medical uses of these plants were compiled from the literature. Study area was located on the East of Anatolian diagonal, in the Eastern Anatolia Region. Field study was carried out over a period of approximately two years (2010-2012). During this period, 82 vascular plant taxa were collected. The plants were pressed in the field and prepared for identification. A total of 82 food plants belonging to 28 families were identified in the region. In the study being conducted, use of wild plants as food points out interest of people in Catak in wild plants. The fact that a large proportion of edible plants are also being used for medicinal purposes indicates that the use of wild plants has a high potential in the region. The present study shows that further ethnobotanical investigations are worthy to be carried out in Turkey, where most of knowledge on popular food plants are still to discover. In Turkey, the number of ethnobotanic studies is ever-increasing. However, traditional uses of many wild plants have not been recorded yet. In terms of food safety, the adverse effects that may arise due to the use of wild plants without sufficient knowledge must be reported to the native people.

Multi criteria decision making (MCDM) is one of the research areas of operations research and management science which has widely studied by researchers and practitioners. It finds a compromise solution for evaluating and ranking alternatives from the best to the worst under conflicting criteria with respect to decision maker(s) preferences. In a compromise approach, the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR; that means multi-criteria optimization and compromise solution) continues to be applied satisfactorily across different application areas. This paper conducts a state-of-the-art literature review to categorize, analyze and interpret the current research on VIKOR applications. It also discusses the extensions of VIKOR applied in fuzzy environments. A total of 343 papers are classified into 13 different application areas and a number of sub-application areas. Furthermore, all papers are also categorized with respect to publication year, published journal, country of origin, application type (real case study vs empirical study), and version of fuzzy sets used. This comprehensive literature review provides an insight for researchers and practitioners on VIKOR applications in terms of showing current state and potential areas for future attempts to be focused in the future.

Gül, Serpil; Kaya, Mehmet; Kaya, Buket
This paper proposes a link prediction method to estimate what sort of disease risks may have been carried by the patients via surveying their and similar patients' medical histories. It is possible to make future oriented predictions with link prediction by deriving new data within a network structure. It is attempted to estimate the future structure of the network and the relations which will be created or abandoned by the individuals on the basis of the nodes within the network structure and the relations between these nodes. For this purpose, an undirected weighted disease network is first created by using the data of patients which were subjected to Hemogram test at F. rat University Hospital during 2013. In the disease network, each node represents a disease and the links represent a relationship between diseases. By the developed method, then disease risk prediction is made through a proactive approach by determining what sorts of disease risks were carried by the patients applying with certain complaints. Experimental results demonstrate the applicability of the link prediction in these networks.

In this study, an FPGA based online monitoring system was developed for detection of power quality disturbances. The developed system has the capability to instantly detect commonly seen PQ disturbances such as voltage sag, voltage swell and interruption occurring on real-time three-phase voltage signals obtained from the electric power system. The data of the detected disturbance events are transferred to the visual software prepared in the computer environment by means of the UDP/IP communication module embedded in the FPGA. This PQ disturbance detection system was tested upon installation at three different measuring points across the campus of Tunceli University. It was seen from the test results examined that the detection system successfully identified the PQ disturbance events.

Celik, E.; Erdogan, M.; Gumus, A. T.
In this paper, first, the criteria that make logistics service providers more green'' are determined as: cooperation with customer's company and its customer, green government regulations, environmental management system, green process design, reduction in energy consumption and green network design. The criteria weights are determined by fuzzy AHP, based on expert opinions. Then, a new method is proposed, which is the combination of fuzzy TOPSIS and GRA, and used to evaluate green 3PLs based on different separation measures, as an extension, using trapezoidal fuzzy numbers. Five Turkish 3PLs serve in Istanbul are selected in order to apply a case study to show the applicability of the proposed method. Finally, the proposed method is verified with respect to different resolving coefficient values and separation measures and also compared with fuzzy TOPSIS and fuzzy VIKOR method results. Different multi-criteria decision-making methods can be applied and compared to check validity of our results for future studies. The proposed method can also be implemented to 3PLs in other countries.

The biosorption of heavy metals, radionuclides, uranium and thorium for the recovery or removal from aqueous systems using various micro-organisms and biological substances has been investigated by several groups of workers. In this paper, the uptake of uranium (VI) from aqueous systems by a marine sponge, Sarcotragus foetidus (Schmidt, 1862) has been investigated. S. foetidus samples were collected from Babakale/Ayvacik/Canakkale in Turkey. Uranium (VI) uptake experiments were carried out by the batch technique. The affecting parameters were analyzed using Central Composite Design (CCD) as the experimental method. Four independent variables such-pH, temperature, contact time, and initial uranium concentration were selected for this study. The influences of initial pH, contact time, and initial uranium concentration on the biosorption process were considered statistically significant as main effects. On the other hand, interaction effects of pH and contact time, as well as pH and initial uranium concentration, were considered as significant parameters on the biosorption process. The optimum condition of biosorption process was found to be at initial pH: 4, temperature: 35 degrees C, initial uranium concentration: 20 mg/L, and contact time: 31 minutes. At these conditions, the biosorption yield of uranium (VI) ions was obtained to be 93.29 +/- 2%.

Eristi, Belkis; Yildirim, Ozal; Eristi, Huseyin; Demir, Yakup
Disturbances occurring on voltage signals following switching events or faults on power systems are defined as power quality problem. Power quality problems result in significant financial losses in the power systems in addition to faulty operation or breakdown of sensitive loads connected to the power system. Therefore, power quality problems should be swiftly detected and eliminated. This paper proposes a real-time embedded detection system for the purpose of identification of power quality disturbances. The detection system developed has been created using the wavelet transform in the Field Programmable Gate Array (FPGA) media. The general structure of FPGA-based detection system comprises two fundamental parts: hardware and software. Hardware structure comprises signal input card, FPGA and computer components. The software stage includes FPGA and graphical interface software. An experimental setup of the power system has been created in laboratory environment in order to test the FPGA-based detection system, determine accuracy rates and assess its success. Various power quality disturbances have been created over this model in wide parameter intervals. When the results obtained for the real-time power quality disturbance detection system developed under this study are examined, it has been seen that hardware and software designs are quite effective, fast and of high achievement performance.

Sahilli, Yeliz Cakir; Akgun, Mehmet Hanifi; Yildiz, Deniz
Antimony is a trace element which has wide variety of industrial application. Antimony has recently been considered as an environmental pollutant. Among the inorganic forms, SbIII is the more toxic form. SbIII is ten times more toxic compared to the SbV. Consuming plants that are grown in antimony contaminated soil is one of the way by which humans are exposed to antimony. AsIII and SbIII forms strong bonds with free-SH groups. When SbIII or SbV interacts with proteins that contain free-SH groups, protein inactivation usually results in. Antimony may also result in free radical generation and induction of oxidative stress. Even though antimony has some applications in health as a drug, its biological effects have not been investigated in detail. In the present study we investigated the effects of SbIII on glutathione efflux in human erythrocytes. The effects of N-acetyl-L-cysteine on antimony induced glutathione oxidation and glutathione efflux were also investigated. Extracellular glutathione concentration significantly increased and reached to 0.033 +/- 0.0034 micromole/ml erythrocyte with 1 mM of potassium antimony tartrate in four hours. The control value of extracellular glutathione was 0.020 +/- 0.0035 micromole/ml erythrocyte. Our results show that SbIII treatment of erythrocyte results in glutathione efflux.

Say, Y.; Aksakal, B.
To improve corrosion resistance of metallic implant surfaces, Rex-734 alloy was coated with two different bio-ceramics; single-Hydroxyapatite (HA), double-HA/Zirconia(Zr) and double-Bioglass (BG)/Zr by using sol-gel method. Porous surface morphologies at low crack density were obtained after coating and sintering processes. Corrosion characteristics of coatings were determined by Open circuit potential and Potentiodynamic polarization measurements during corrosion tests. Hardness and adhesion strength of coating layers were measured and their surface morphologies before and after corrosion were characterized by scanning electron microscope (SEM), XRD and EDX. Through the SEM analysis, it was observed that corrosion caused degradation and sphere-like formations appeared with dimples on the coated surfaces. The coated substrates that exhibit high crack density, the corrosion was more effective by disturbing and transmitting through the coating layer, produced CrO3 and Cr3O8 oxide formation. It was found that the addition of Zr provided an increase in adhesion strength and corrosion resistance of the coatings. However, BG/Zr coatings had lower adhesion strength than the HA/Zr coatings, but showed higher corrosion resistance.

Benzer, Fulya; Özçelik, Mehtap; Yildirim, Nuran Cikcikoglu
The effects of dietary antioxidants (vitamine E, vitamine C, Astaxhantin, beta carotene) on arginase activity and nitric oxide levels of hepatopancreas and muscle of freshwater crayfish (Actacus leptodactylus) were investigated during moulting. 150 mg kg(-1) vitamine E (VE), 200 mg kg(-1) vitamine C (VC), 200 mg kg(-1) Astaxhantin and 200 mg kg(-1) beta carotene were added to experimental diets. A. leptodactylus with these diets were fed with 2% of their total weight daily, in a day during 75 days. Arginase activity was increased in muscle of crayfish fed the diets VC, VE, astaxanthin and beta karoten but in hepatopancreas arginase activity was increased with beta carotene when compared to control. NO levels in muscle were decreased when compared to control but this decrease was not statically significant. NO levels in hepatopancreas of crayfish fed the diets VC and astaxanthin were higher than control groups. Our results demonstrated that dietary antioxidants affect the arginase activity and nitric oxide level of freshwater crayfish (Astacus leptodactylus, Esch. 1823) during moulting.

Fe(II) and Zn(II) complex series have been synthesized from Schiff base ligands derived from furan-2-carbaldehyde and thiophene-2-carbaldehyde. Elemental, infrared, ultra-violet- visible, NMR and thermal analysis, also mass spectroscopy and magnetic susceptibility measurements were performed to explain the structures of these synthesized ligands and their metal complexes. The formulas based on analytical, spectral, and magnetic studies, the complexes can be demonstrated as [M(L-1)(2)](H2O)(n), [M(L-2)(2)](H2O)(n), where M = Zn(II) and Fe(II). An octahedral geometry was suggested for the Zn(II) and Fe(II) complexes. The antioxidant, antiradical and antimicrobial properties of the Zn(II) and Fe(II) complexes were investigated using different in vitro assays. Some of the complexes showed reasonable amount of antioxidant and antimicrobial activity.

Yilmaz, D.; Sabre, M.; Lassabatère, L.; Dal, M.; Rodriguez, F.
Green roofs are promising urban management tools from the standpoint of both rainwater management and microclimatology. They are considered as a storm water mitigation technique and may also favour evapotranspiration fluxes, which can be beneficial for urban comfort during summer periods. In France, however, water retention performance of green roofs remains unknown, and published values are often unsuitable. Six experimental roofs, including two thicknesses of growing media, three types of vegetation cover and bare surfaces, were monitored for two years in Nantes and compared to an experimental gravel flat roof. The thickest media combined with the most densely vegetated cover yields the best results in terms of storm water mitigation and actual evapotranspiration. In winter, the rainwater retention performance is clearly dependent on the type of experimental roof vegetation. This kind of experimental set-up is well suited to assisting urban planners design tools for storm water mitigation in buildings.

Objectives: To investigate the affects, information requirements and self-perceptions of Turkish women undergoing hysterectomy. Methods: A descriptive cross-sectional study was conducted on 37 Turkish women undergoing hysterectomy and followed in a gynecology unit of a state hospital in Canakkale, Turkey, between February and August 2012. Data were collected before discharge with a questionnaire composed of 32 questions. Percentage distributions and Chi-square test were used in the evaluation of the data. Results: There was a significant relationship between fear of anesthesia and number of pregnancies (p=0.007) and between death during surgery and number of pregnancies in the preoperative period (p=0.027). The relationship between knowing type of surgery and knowing when sutures would be removed was also significant in post-operative period (p=0.045). In addition, there was a significant relationship between women's living only with their husbands and worrying about not having children anymore (p=0.032). Conclusion: The women's information needs were high and women's self-perceptions had been affected negatively after hysterectomy. It is recommended that nurses, primarily health professionals should have adequate knowledge on comprehensive care and psychosocial support after hysterectomy.

Sandulyak, Anna A.; Sandulyak, Alexander V.; Bulut, Hasan; Baskonus, Haci Mehmet; Polismakova, Maria N.; Sandulyak, Darya A.; Mastorakis, N; Mladenov, V; Bulucea, A
The paper demonstrates that when defining the content of ferroimpurities in the analyzed media by magnetic control based on measuring the ferroimpurities masses m, which are extracted from the media sample step-by-step, it is crucial to define a functional view of the obtained dependence m on the operation order number n. It allows receiving additional forecast data m by extrapolating this dependence. With corresponding calculations being done, it enables determining the sought total mass of ferroimpurities (including their residual mass). We consider alternate solutions of practical tasks which yield magnetic control results in case of linear and piecewise-linear views (in semi-logarithmic coordinates) of the control mass-operational characteristics.

Introduction: This study aimed to identify the Quality of Life (QOL) and associated factors among rural elders. They represent a growing percentage in the national population today and have become increasingly isolated in villages that are being drained due to migration flows from rural to urban areas. Materials and Method: The universe of the present cross-sectional study consists of people of and over the age of 65 living in villages of the Zara district in Sivas Province. The study sample is composed of 20 villages and 577 elderly individuals living in these villages. The data were collected with the use of a personal information form, the WHOQOL-Bref QOL scale, the Geriatric Depression scale, and the Barthel Index of Activities of Daily Living through face-to-face interviews. The data thus obtained were evaluated on the SPSS software through the implementation of the distribution measures, Mann-Whitney U test, and Kruskall-Wallis Variance test. Results: Twenty-five per cent of the elderly individuals included in the study perceive their health status as being poor. The difference between gender, age, education, economic status, health perception, dependency information, and score averages in all subfield scores of QOL among the elderly was found to be statistically significant (p<0.05). Conclusion: Advanced age, female gender, chronic disease, depression, perception of health as poor, dependency, and constantly living in a village were determined to be among the negative factors that affect the elderly's QOL.
