    Effects of Priming to Some Physiological Parameters on Winter Bread Wheat (Triticum aestivum L.)
    (2015)
    The study was conducted to determine effects of seed priming to physiological parameters (PP) at drought conditions (DC) on bread wheat cultivars (Triticum aestivum L., Altay 2000 and Kirac 66) at Selcuk University Agricultural Faculty Controlled Climate Chamber and Physiology Laboratory. Effects of seed priming on PP measured using randomized plot design with three replications, two bread wheat cultivars (Altay 2000 and Kirac 66), five treatments (Control, 0,1% NaCl, 0,5% KH2PO4, 2% KCl and H2O), two sampling times (7th and 14th days after emergence) and two conditions [drought(DC) and normal(NC)]. Seeds were soaked solutions for twelve hours, then were dried till back to untreated moisture level by mixing at room conditions and sowed NC (irrigated as needed) and DC (soil saturated with 25% distilled water for 48 hours) pots. Seeds without treatment were used as control group. Seventh and fourteenth days after emergence physiological parameters [(chlorophyll content (CC), stomatal conductance (SC), photosynthetic efficiency (PE), proline content (PC), MDA (malondialdehyde)] were determined. MDA level at DC is (37, 62 nmol/g) higher than NC (32, 17 nmol/g). At NC except MDA and PC, all parameters increased. PC level of plant materials at DC (9, 44 µmol/g) was significantly higher than PC of NC (4, 76 µmol/g). Seedlings from primed seeds, better adapted to DC. Seedlings grew primed seeds have more CC, less MDA. CC of Altay 2000 at DC (38, 96 spad) significantly decreased compared to NC (48, 92 spad). The same situation was came across with Kirac 66 also (DC; 34, 69 spad; NC; 47, 38 spad). Generally response of seedlings Altay 2000 to priming was better than Kirac 66. According to results, it is observed that seed priming is a practical method, can be used drought areas. Pre-treatment is an alternative method that can trigger resistance towards water deficit conditions.

    (Selçuk Üniversitesi, 2015) Cakiroglu, Melda Alkan; Ince, Gulhan; Tekeli, Hamide; Demir, Fuat; Cakiroglu, Gokhan Murat; Yedek, Cigdem Yigit
    In our country, in rural and urban areas a significant portion of the existing structure was built as a masonry structure. The most important reason of prefer is easy supply of building materials. But despite widely available in our country, behavior of masonry structures against earthquakes is adequately understood. Therefore, knowledge of earthquake behavior of existing masonry structures and the development of strengthening methods is an important issue. About of strengthened masonry structures is need effective and economical. Especially behavior under the influence of lateral loads of masonry structures need to be examined. Behavior and strength of reinforced brick walls with the application of dry mix shotcrete on steel mesh were experimentally investigated in this study. In the first stage of the experimental study, brick wall specimens were produced. One of these samples were left in the simple case, the other was applied dry mix shotcrete 5 cm in thickness on steel mesh. Simple and reinforced brick walls were made loading as out of plane and cyclically. When the experimental results were evaluated, the energy absorption capacity and load-bearing capacity of brick wall reinforced with shotcrete is seen to increase significantly.

    Bayesian Nonlinear Structural Equation Modeling
    (Selçuk Üniversitesi, 2015) Altindag, Ilkay; Genc, Asir
    Structural Equation Modeling (SEM) is a multivariate method that incorporates ideas from regression, path analysis and factor analysis. SEM has been widely applied in examine inter-relationships among latent and observed variables in social, psychological, and medical research. Generally linear relationships between observed and latent variables are modeled in SEM. Also, modeling of nonlinear relationship in SEM have attracted great attention in the literature. A Bayesian approach to SEM may enable models that reflect hypotheses based on complex theory. The Bayesian approach analyses a general structural equation model that accommodates the general nonlinear terms of latent variables and covariates. In this study, we apply Bayesian SEM for Self-Esteem Scale.

    Evaluation of Water Quality Using Fuzzy Logic in Beykavagi Pond, Turkey
    (Selçuk Üniversitesi, 2015)
    Water pollution is one of the biggest problems at the present time. To determine this pollution, it is used classic methods generally and there are different tables which contain lower and upper limits. The results hold equal significance even if they are close or far away while obtained results are evaluated according to these tables. Thus every quality parameter located in one of the classes in the table. In this research, water samples were taken from Beykavağı Pond on a monthly basis between the dates April 2010-Mart 2011. It was measured 27 physico-chemical parameters totally as Temperature, Dissolved Oxygen, Turbidity (NTU), Electrical Conductivity, Biological Oxygen Demand, Chlorophyll-a, Ammonium, Total Phosphate, Chloride, Magnesium, Calcium, Nitrate, Nitrite, Potassium, Sulphate, Total Hardness, Aluminum, Copper, Zinc, Iron, Cadmium, Cobalt, Chrome, Lead, Manganese and Nickel. According to results obtained in Beykavağı Pond, index model was used in which water pollution control is evaluated with fuzzy logic as well as classic method and water quality classification. As the result of analysis made with fuzzy logic, water quality divided into four groups (I, II, III, IV). Consequently due to fuzzy logic statement, in Beykavağı Pond was provided the homogeneity between measured parameters and it was seen that 66% of quality index is in II category, 34% in III category when we calculated annual quality index which we obtain according to output value. Also in evaluation of water quality parameters as a whole it's thought that fuzzy logic method can be used as a tool. With this research, it was presented first findings for creation of fuzzy logic based index for water quality in our country.

    Determination of Outlier in Live-Weight Performance Data of Japanese Quails (Coturnix coturnix japonica) by Dffits And Cook's Distance
    (Selçuk Üniversitesi, 2015) Inci, Hakan; Bahadir, Burhan; Karadavut, Ufuk
    The data on live weight performance usually show a normal distribution. On the other hand, the majority of the statistical analysis methods have been developed on the basis of the assumption that the data under consideration are normally distributed. From time to time, in the analysis of the obtained numerical values, one or more observation are found to be quite far away from other observations. Such values are named as extreme value, deviated value, and outlier value. This study has been carried out by using Cook's distance and DFFITS criteria, with intent to determine the outliers of the live weight performance data of the japanese quails, which has been classified according to their sex and have grown until the age of 70 days (10 weeks). In conclusion, it can be said that the DFFITS values are higher than COOK’s distance in male, female, and flock total. DFFITS method is a method that finds more outlier values when compared to COOK’s distance method in terms of finding outlier. DFFITS method should be used if precision is wanted to be enhanced, and COOK’s distance method should be preferred in less precision studies.

    Do some relative entropy measures coincide in determining correlations or associations for metric data?
    (Selçuk Üniversitesi, 2015) Evren, Atif Ahmet; Dincer, Gokhan
    Entropy is a measure of uncertainty of a statistical experiment or the measure of information provided by experimentation. Several measures of entropy are used in uncertainty considerations for nominal, ordinal (as well as metric) data and specifically in qualitative variation calculations. Besides, relative entropy concepts (e.g. mutual information, etc.) are used in goodness of fit tests or in checking the adequacy of any statistical model in general. In particular, relative entropy measures are used in correlation or association estimations. In this study, based on a specific definition of mutual information, we use some different relative entropy measures. Then we compare these measures under three different situations by some applications.

    Investigation of Fe(III) bonding properties of tetracaine using spectrofluorimetric method
    (Selçuk Üniversitesi, 2015)
    The metal bonding properties of tetracaine (TCN) were investigated by using spectrofluorimetric method. Fluorescence quenching of TCN by Fe(III) was studied and optimal experimental conditions were determined. The excitation and emission wavelengths were lex= 306 nm and lem= 373 nm for the Fe(III)-TCN complex in water medium. The calibration curve was obtained from Stern-Volmer equation plotting to F0/F-[Fe3+] graphs and the linearity was found within the range of 0.22-2.23mg.ml-1 for the Fe(III)-TCN complex under optimal conditions. The detection limit (LOD) and the quantitation limits (LOQ) of the proposed method for this complex were 8.29 ng.ml-1 and 27.60 ng.ml-1 respectively. The stochiometry of this complex was also determined by using the continuous variation method and the molar ratio of Fe(III)-TCN was calculated as 1:1. The interaction between the tetracaine in eye drop form and standard Fe(III) was investigated by applying this quenching method and obtained satisfactory results.

    A New Method for Recycling of Metal Chips
    (Selçuk Üniversitesi, 2015)
    As a result of machining a vast amount of metal chips are formed. These metallic chips can be recycled by melting. The high amount of energy required for melting process significantly increase the cost of recycling and it causes environmental pollution because the required energy generally derived from fossil fuels ( Gronostajski J.; Matuszak A., 1999 ). Therefore, researchers are working on alternative methods for the recycling of chips in order to reduce usage of fossil fuels and environmental pollution as a result of utilization of fossil fuels. In this study the possibility of the recycling of metal chip by means of hot pressing under particular temperatures and pressures instead of conventional melting recycling process has been investigated. A new metal matrix composites which are compose of spheroid graphite cast iron SGCI(GGG-40) and tin-bronze(CuSn10) was produced by this new sustainable method.

    Metal Talaşların Geri Dönüşümü için Yeni Bir Yöntem
    (Selçuk Üniversitesi, 2015)
    İşleme sonucunda çok miktarda metal talaş oluşur. Bu metalik çipler eritilerek geri dönüştürülebilir. Eritme işlemi için gereken yüksek enerji miktarı, geri dönüşüm maliyetini önemli ölçüde artırır ve çevre kirliliğine neden olur çünkü gerekli enerji genellikle fosil yakıtlardan elde edilir (Gronostajski J .; Matuszak A., 1999). Bu nedenle araştırmacılar, fosil yakıtların kullanımı sonucunda fosil yakıtların kullanımını ve çevre kirliliğini azaltmak için cipslerin geri dönüşümü için alternatif yöntemler üzerinde çalışıyorlar. Bu çalışmada metal talaşın geleneksel ergitme geri dönüşüm prosesi yerine belirli sıcaklık ve basınçlarda sıcak presleme ile geri dönüşümü araştırılmıştır.
