Hydrogen transfer reduction reactions have been attracted significant attention in organic synthesis due to their operational easiness. For this purpose, two Ru(II) complexes of P-N-P ligand were prepared starting from [Ru(?6-p-cymene) (µ-Cl)Cl]2. Then, their catalytic activity was investigated in the transfer hydrogenation of different simple alkyl and aryl alkyl ketones to respective alcohols in the existence of isopropanol as the hydrogen source. Notably, 2 exhibits a good catalytic activity and affords the respective alcohols with good conversions up to 98 % (TOF: 392 h-1).

In this study, Staphylococus aureus strain was isolated in 125 of the samples of 180 patients’wounds who were hospitalized in Mardin State Hospital Orthopedic Service and implanted, while Staphylococus epidermitis strain was isolated in 62 of them. In these isolates, it was aimed to determine the presence of ica A and ica D genes responsible for slime production by Multiplex PCR, to determine slime production by phenotypic methods such as Congo red agar (CRA), standard test tube (ST) and microplate (MP) and to determine the role of the slime (biofilm) layer in the resistance mechanism by looking at the antibiotic resistance of the strains with disc diffusion agar. While the CRA, MP and ST tests of the Staphylococcus strains examined were found to be respectively 62.4%, 57.7% and 52.9% positive, the ica A and ica D gene positivity was 65.6% (82/125). It was determined that all staphylococci examined were sensitive to teicoplanin and vancomycin antibiotics. While antibiotic resistance rates were higher in slime positive strains than slime negative strains, only penicillin, ampicillin and erythromycin resistance rates were found statistically significant. As a result, resistance to antibiotics was found to be significant in strains positive with regard to ica A and ica D genes.

Knowing the oktas values, defined as the ratio of the amount of cloud in the sky, is very important in agricultural production, utilization of solar energy and similar issues. Determination of oktas can be made by using other approaches instead of direct measurement due to measurement errors and direct measurements being laborious, time consuming and costly. In this context, climate data sets such as evaporation (Ea), precipitation height (P), relative humidity (RN), sunshine times (Sgs), wind speeds (Rh), average temperature (Tave), minimum temperature (Tmin) and maximum temperature (Tmax) were obtained from Sakarya meteorological station. Considering the sunshine periods, the cloud status of the sky was examined with a new statistical approach and a model was developed and oktas values were tried to be estimated. Estimates obtained from the model were compared with observation values. The relationship between them was determined by the coefficient of determination (R2) and it was observed that the statistical model gave good results in the estimation of oktas.

The effective a selection made with suitable methods in barley breeding studies increases the success of breeding programs, and it is effective in requiring suitable variety candidates. In this study, the visuality of the biplot technique and the results of AMMI (Additive main effects and multiplicative interaction) analysis were also used for an effective selection. The study was carried out in Diyarbakir province with three repetitions in random blocks trial design in 2010-11 and 2011-12 growing seasons under rainfall conditions. In the study, 5 varieties which used commonly in the region along with 20 lines in two and six rows of advanced level obtained from national and international (ICARDA) hybrid programs were used. According to variance analysis results, significant differences were detected between genotypes in terms of p <0.01 and 0.05 levels. In addition, all the traits were handled together with the biplot technique and superior genotypes were identified. According to the results of the analysis; grain yield is 4724 to 7581 kg/ha-1 , the heading time is 113 to 123 days, plant height is 87.5 to 130 cm, hectoliter weight is 57.3 to 71.8 kg / hl, protein content is 12.6% to 17.2, thousand grain weight is 33.8 to 44.3 g and starch ratio is 67.6 to 71.1%. According to the results, two advanced lines exceeded all standards in terms of grain yield and 11 lines in terms of hectolitre weight, also the lines showed a high variation in terms of other traits (in terms of grain weight, protein ratio, starch rate, plant time and plant height). As a result, it has been determined that biplot technique can be used for a more effective selection. According to the results of variance and biplot analysis, 10 lines used in the research were chosen to be moved to the next level as candidates for variety, since they have better results than the controls used in the research in terms of the characters investigated.

Some of the farmers believe that agronomic applications had different results according to the moon positions. For this reason, it was aimed to determine the effect of different sowing dates arranged according to the moon positions, on the yield and quality traits of some maize varieties (Zea mays L.) produced as second crop after wheat. Research was carried out in Kahramanmaras conditions, in 2016 year, Truva, OSSK-644 and Ada-9510 cultivars used as experiement material. In research, the agronomical and quality traits were investigated. According to the results of the research; sowing dates had effect on some agronomical and quality traits As a result; unlike as believed by farmers; there was not any significant effect of sowing dates arranged according to the moon positions on the yield, agronomical and quality traits of silage corn produced as a second crop.

In this research, it was aimed that evaluation of some oat (Avena spp.) genotypes (lines and cultivars) sown on summer-end in July and on fall in December for green hay yield, dried-biomass yield and silage quality traits. Research was carried out in Kahramanmaras conditions, in 2016-2017 seasons with total 13 oat genotypes. According to completed analyzing; all investigated agronomical traits were significantly different for sowing dates. A silage quality trait was significantly different for sowing date.

The rapid industrialization in poultry and the development of closed systems, which replaced the traditional role of small businesses in egg production, have resulted in chickens that have not been able to move freely in nature. In this regard, in order to improve the internal and external quality characteristics of the egg, it became necessary to include feed additives to their diet. There are many research studies to improve egg quality by using various nutrients or feed additives. In this article, current feeding studies that give the egg a functional feature and affect both the internal and external quality of the egg are discussed
