Erguven, G. O.; Bayhan, H.; Ikizoglu, B.; Kanat, G.; Nuhoglu, Y.
Bioremediation is the use of microorganisms to degrade environmental contaminants (pesticides, polyaromatic hydrocarbons etc.) into less toxic forms or compounds. In this study microbial biodegradation of trifluralin was performed in liquid media with 11 different types of identified fungi and bacteria cultures and their mixtures in agiated culture media. The isolated fungi and bacteria mixtures showed the highest degradation, reaching 93% in the chemical oxygen demand (COD) parameter in four days and 82% as trifluralin active ingredient in five days. Bacteria and fungi mixtures achieved 69% and 66% degradations of trifluralin active ingredient respectively. In the fungi studies, the best removal was achieved by M. Chlamydosporia at 80%, in the bacteria studies, the best removal was achieved by Bacillus simplex about 95% in five days. These different removal rates were due to the microbial differencies.

Islak, S.; Çelik, E.; Kir, D.; Özorak, C.
In this study, the CuAl-TiC composite materials were produced using hot pressing process. Effect of TiC grain size (0.2, 4 and 20 mu m) on some properties of these materials was investigated experimentally. Production of CuAl-TiC composites was carried out under pressure of 35 MPa, at 700A degrees C, and for a sintering time of 5 minutes. SEM-MAP studies showed that the TiC grains were relatively homogeneously distributed in the CuAl matrix. Microstructure analysis revealed that the composite materials consist of Cu, Al, Cu9Al4, CuAl2 and TiC phases. With the decreasing of TiC grain size, the hardness, transverse rupture strength, relative density and sintered density of composites increased.

Sushi is a popular traditional Japanese food in worldwide. This study was conducted to investigate the physical, chemical, sensory and microbiological quality of sushi sold in supermarket and restaurants. 300 sushi samples were purchased from 5 different popular restaurants (A, B, D, E, and F) and 1 supermarket (C). Four main types of sushi (California roll (CR), sesame roll (SMR), sake roll (SR), take roll (TR)) were chosen from each station. pH values of sushi rice samples were found to be all below 4.6. According to sensory overall quality of sushi samples, CR and SMR from station C had significantly the lowest values (p<0.05). Among the sushi samples, pathogenic bacteria Listeria monocytogenes, Salmonella spp. and Staphylococcus aureus were not detected in 25 g portion of any samples. Counts of total aerobic bacteria were high in stations A, B, D, E, and F (between 4.3-7 log CFU/g), except for station C (3.5 log CFU/g). Results for coliform counts showed similar trends as those of E. coli counts in samples. E. coli counts of all sushi types from all stations (except SMR, SR and TR from station D and SR from station E) exceeded the limit of acceptability (<100 MPN/g). Our finding may suggest a common presence of coliforms and E. coli in raw materials used in sushi preparation.

Say, Yakup; Aksakal, Bunyamin; Dikici, Burak
REX-734 stainless steel alloy was coated with hydroxyapatite (HA)-silicon dioxide (SiO2) composite (hybride) coatings by using the sol-gel method. Surface morphologies, adhesion resistances and corrosion behaviors of the coatings were examined and the characterization of the coatings was performed by using XRD, SEM, and EDS. It was observed that porous and crack-free surface morphology enhanced adhesion strength of the coatings. Through the shear tests, it was found that the adhesion resistance was 25.14 MPa in HA coatings and 25.47 MPa in HA-SiO2 coatings. Corrosion analyses of the coatings were performed by using potentiodynamic polarization (PDS) tests. It was determined that corrosion dimples formed on the coating surface and the corrosion resistance in HA+SiO2 coatings increased with decreasing porosity; however, in the further steps of corrosion, it reached to the base material by causing a pitting effect on the coated surface.

Gul, Muhammet; Guneri, Ali Fuat
Earthquakes over the world cause serious damages for people and the economy. The establishment of an appropriate model to estimate potential losses or injuries in earthquake disasters is fundamental to decrease their impacts and losses and effectively respond and mitigate. Turkey as a country that experienced many earthquakes in the last century and had serious human and financial losses needs a comprehensive knowledge of consequences of devastating earthquakes to be able to plan for the future. Artificial neural networks (ANNs) have abilities to solve and analyse complex relations as an appropriate method to estimate number of injuries. In this study, an ANN model is built up for the earthquake casualty prediction, which takes earthquake occurrence time, earthquake magnitude, and population density as the predictors and employs 21 Mw > 5 earthquake disasters occurred in Turkey from 1975 as samples for the training of the network. The model was then tested on a study region consisting of four districts in Istanbul which is estimated to have the highest injury rate according to the earlier reports and generated estimations of the expected number of injured people. Results show that 99.9 % of the variability in the number of injured people is predictable with using this ANN model. Comparison of actual values and estimated output values in the ANN model was also found apparently very close to each other. According to the test case study results, when the value of earthquake magnitude is 6.5 Mw, number of injured people has increased in a sharp trend compared to the previous magnitude value (6 Mw) for all districts. Estimated number of injured people in daytime is obtained higher than at night when the earthquake magnitude is 5 and 5.5 Mw. The highest value in estimated number of injured people has emerged in Fatih district as 7241 for a 7.5 Mw daytime earthquake. On conclusion, it was deduced that the model can reveal accurate estimation of casualties and it can provide information in order to develop mitigation policies, especially in earthquake emergency service management.

Yigit, Emel; Akbulut, Gulcin Beker; Bayram, Dilek; Kaya, Armagan; Gok, Yetkin
The present study focuses on understanding the role of different antioxidants in plant defense against oxidative stress caused by fenoxaprop-p-ethyl herbicide. Besides ameliorative effect of exogenously applied salicylic acid (SA) and selenium (Se) on fenoxaprop-p-ethyl-induced toxicity was examined in Avena sativa L. It was determined that the MDA (malondialdehyde) content in the groups to which only herbicide was applied was higher than that of the groups to which SA and Se applied together with the herbicide. In plants exposed to fenoxaprop-p-ethyl, the activities of peroxidase (POD), ascorbate peroxidase (APX), superoxide dismutase (SOD), glutathione S-transferase (GST), glutathione reductase (GR) and content of glutathione (GSH) increased in the treatment groups compared to the control groups. The antioxidant activity increased in the control and treatment groups that were pre-treated with SA and Se compared to the groups that were not pre-treated with SA and Se. While catalase activity (CAT) decreased in SA pre-treated plants, it increased in Se pre-treated plants. These results indicate that the fenoxaprop-p-ethyl induces various plant defense responses in target plants and that treatment with exogenous SA and Se can increase stress resistance by altering these responses.

Gul, Muhammet; Guneri, Ali Fuat
Decision matrix risk-assessment (DMRA) technique is a systematic approach widely used in the Occupational Health and Safety (OHS) risk assessment. In a typical matrix method approach, a measure of risk value is obtained by evaluating two risk factors as the likelihood of a hazard and the severity of the hazard when it arises. In this paper, a fuzzy approach enabling experts to use linguistic variables for evaluating two factors which are the parameters of matrix method is proposed to deal with shortcomings of a crisp risk score calculation and to decrease the inconsistency in decision making. The parameters likelihood and severity related to the hazards in an aluminum plate manufacturing plant are weighted by using Fuzzy Analytic Hierarchy Process (FAHP), then the orders of priority of 23 various hazard groups are determined by using Fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. As a follow-up study of the case application, the proposed risk assessment methodology is applied for hazard types in each department of the plant. Depending on the hazard control hierarchy, control measures are overtaken for the hazards that are placed at first of intra-department rankings. (C) 2015 Elsevier Ltd. All rights reserved.

Karaaslan, Nagihan M.; Yaman, Mehmet
Anthocyanins are a group of widespread natural phenolic compounds in vegetables and fruits. The anthocyanins have a wide range of applications due to the antioxidant, anticancer and anti-inflammatory properties. In this study, anthocyanins (delphinidin-3-o-glucoside, cyanidin-3-o-glucoside, pelargonidin-3-o-glucoside and malvidin-3-o-glucoside) in cherry and cranberry were determined using high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS). The anthocyanins were separated using gradient elution and a reserved-phase analytical column before identification by high-performance liquid chromatography-electrospray ionization-mass spectrometry. A high-performance liquid chromatography-electrospray ionization-mass spectrometry method was optimized for the determination of anthocyanins in cherry and cranberry. Furthermore, in this study, we investigated extraction conditions of fruit samples as well as determination of optimum HPLC-ESI-MS conditions. This study is novel in terms of simultaneously examining both optimization of HPLC parameters and extraction conditions. Obtained optimum conditions were used for the determination as the quantitative and qualitative analysis of anthocyanins in cherry and cranberry. The content of anthocyanins on the basis of wet weight in cherry and cranberry samples was determined for delphinidin-3-o-glucoside < d.l. (detection limit) and < d.l., for cyanidin-3-o-glucoside varied from 3.5 +/- A 0.4 to 8.3 +/- A 1.1 mg kg(-1) (average 5.8 +/- A 0.8 mg kg(-1)) and 9.8 +/- A 1.4 to 18 +/- A 3.0 mg kg(-1) (average 13.2 +/- A 1.8 mg kg(-1)), for pelargonidin-3-o-glucoside < d.l. and varied from 136 +/- A 19 to 233 +/- A 35 mg kg(-1) (average 185.3 +/- A 28 mg kg(-1)), for malvidin-3-o-glucoside < d.l. and < d.l., respectively.

Asbestos is dangerous for health and is forbidden to use in Turkey, but villagers who live in rural eastern part still use it especially for their home for insulation purposes and even as a substitute for baby powder. Therefore, geological and chemical properties of this type of soil, which is near the settlement, should be characterized and identified from the point of view of health. Beypinari asbestos deposits are located at Beypinari village, about 90 km southeast of Sivas, Turkey within Central Anatolian Ophiolites. Therefore, in the present study, the existence of chrysotile in Beypinari asbestos deposit were characterized and identified by mineralogical analysis and by major, trace, REE analysis. The results show that the samples contain different amount of calcite mineral, the main mineral being chrysotile.

Can, Safak Seyhaneyildiz; Cirik, Semra; Koru, Edis; Turan, Gamze; Tekogul, Hatice; Subakan, Tugba
Efficient biofuel production from algae depends on the microalgal biomass production rate and lipid content. Both biomass production and lipid accumulation are limited by several factors, of which nutrients play a key role. In this study, the marine microalgae Dunaliella bardawil was used as a model organism. D. bardawil was cultured at two different sodium nitrate concentrations as 0 and 0.7 M, at six different amounts of salinity as 0.65, 1.0, 1.5, 2.0, 2.75 and 3.5 M, and at two different light intensity levels as 65 and 800 mu mol foton m(-2) s(-1) The study was done under pH 7. After 15-day growth period, the most efficient culture of D. bardawil for both biomass increase and lipid production was determined for the samples with 39.67 +/- 4.51 lipid rates cultured under 0.7 M nitrate concentration, 2.75 M salinity and 800 mu mol photon m(-2) sn(-1) light intensity. This high level of lipid production is sufficient to use D. bardawil for biodiesel production. Also after the evaluation of fatty acid results of GC-FID analysis, it was determined that D. bardawil contains high rate of medium length (C16-C18) fatty acid chains suitable for the production of biodiesel. These results are satisfactory to use D. bardawil in biodiesel production.

In this study, adsorption of methylene blue from aqueous solution onto peanut shell has been investigated. Experimental data obtained from dye adsorption have been studied by five two-parameter (Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, and Frumkin) and five three-parameter (Redlich-Peterson, Sips, Toth, Radke-Prausnitz, and Koble-Corrigan) isotherm models. Eight nonlinear error functions (sum squares errors, hybrid fractional error function, Marquardt's percent standard deviation, average relative error, sum of absolute error, the coefficient of determination, nonlinear chi-square test, and standard deviation of relative errors) were examined for isotherm equations. In order to explain the adsorption kinetics fit of pseudo-first-order, pseudo-second-order, Elovich, and intraparticle kinetic models were used. The best fitting isotherm model was the Radke-Prausnitz and kinetics model was pseudo-second-order. Adsorption experiment showed that the maximum capacity of agricultural waste for methylene blue was 67.57 L.g(-1) at 25 degrees C.

Gul, Muhammet; Celik, Erkan; Gumus, Alev Taskin; Guneri, Ali Fuat
Emergency departments (EDs) have an important position in healthcare system environment because of their serviceability to the patients with several illnesses and injuries at all hours of the day and night. Therefore, efficient management of these departments by executives and service providers is only possible with effective tools such as simulation. The concept of multiple criteria decision-making (MCDM) is applicable by computer simulation for decision analysis and performance evaluation of an ED. This study proposes an integration of computer simulation, MCDM methods of interval type-2 fuzzy analytic hierarchy process (IT2FAHP), and ELECTRE for an ED system in a university hospital. Due to the high uncertainty in ED operations, interval type-2 fuzzy sets (IT2FSs) are used in MCDM process. Consequently, the integrated method can be used as a useful tool to evaluate the ED performance and select the best scenario considering different numbers of nurses and doctors for three shifts.

Celik, Erkan; Gumus, Alev Taskin
After a disaster occurs, national and international non-governmental humanitarian relief organizations (NGOs), as well as the governmental humanitarian relief organizations (GOs), are involved in carrying out the humanitarian relief operations because of insufficiency in recourses such as lack of equipment and human resources. GOs and NGOs play a crucial role in preparedness and response to natural disasters, especially when available resources of them are not enough. The preparedness and response ability of GOs and NGOs aim to minimize the losses and number of affected people. Therefore, the preparedness and response ability of NGOs are becoming more important to support governmental relief activities. In this paper, a hybrid approach, that consists of interval type-2 fuzzy sets, AHP and PROMETHEE, is proposed to evaluate emergency preparedness and response ability performances of NGOs. The proposed hybrid approach is applied to NGOs in Turkey to evaluate their performances, and is conducted in three phases: (1) determination of critical success factors (CSFs) of humanitarian relief logistics management operations, (2) application of interval type-2 fuzzy AHP for obtaining importance weights of CSFs and (3) application of PROMETHEE based on interval type-2 fuzzy sets to evaluate preparedness and response abilities of NGOs.

Celik, E.; Akyuz, E.
Accident analyse in marine industry is one of the critical issues for safety practitioners to prevent loss of life. Although considerable efforts were undertaken to prevent marine accident, numerous researches revealed that marine accidents are still on-going. In order to minimize accidents in the marine transportation, this paper presents a proactive decisionmaking tool which is integrating Decision-Making Trail and Evaluation Laboratory (DEMATEL) method with interval type-2 fuzzy sets (IT2FSs). As the DEMATEL enables to analyse cause and effect relationship in decision-making, the IT2FSs overcome ambiguity and vagueness of linguistic assessment of decision-makers through the DEMATEL. Thus, significant accident causal factors and their effects can be analysed on the basis of cause-effect diagram. The application of proposed approach is demonstrated with a real ship collision case. Beside its theoretical contribution, the proposed approach provides practical benefits to ship owners and operators to perceive cause and effect relationship and to avoid marine accident.

Mete, Süleyman; Çil, Zeynel Abidin; Ağpak, Kürşad; Özceylan, Eren; Dolgui, Alexandre
The disassembly line balancing (DLB) problem is the process of allocating a set of disassembly tasks to an ordered sequence of workstations in such a way that optimizes some performance measures (e.g., cycle time, number of stations). Since DLB problems belong to the class of NP hard, many heuristic and meta-heuristic algorithms are applied to cope with the complexity of the DLB problems in order to obtain acceptable solutions in a reasonable amount of time. In this study, a beam search (BS) based approach for the DLB problem is proposed. Minimization of number of workstations is used as the performance measure. The proposed algorithm is compared with the optimal solutions of well-known real cases and generated test problems. The results indicate that the proposed approach based on BS is a very competitive and promising tool for further researches.
