Abstract: In many developing countries, rapid urbanization, disaster risks and affectability pose a great problem. Uncontrolled developments will bring out the inherent risks related with high-density environments and inadequate infrastructure. Advances in mapping hazardous areas have created new opportunities for assessing population vulnerabilities, doing designs to withstand against destructive forces and reducing losses. The aim of this study is to evaluate and compare the most used methods including i) Multi Criteria Decision Analysis, ii) Hydraulic Modeling, iii) Information Diffusion Theory and iv) SCS-CN (Soil Conservation Service Curve Number) in flood analysis. In the light of the results; 1995 buildings were found to be in vulnerable zones in total and 420 of them were found to be in a very high vulnerable zones according to the prepared affectability map. Hydrologic modeling results based on the defined discharge rate showed that 73 hectares of the urbanized area will be affected in the event of 185m3/s of steady flow in Ayamama Creek and these areas were determined in GIS. Based upon the nearest neighbour object-based classification, total of 1859 buildings were defined to be affected by a potential flood. Curve numbers of the catchment were determined by using SCS-CN method and used in Information Diffusion method. According to the results of this method, when the Ayamama Creek reaches 180m3/s of flow rate, the probability of flood occurrence is estimated to be %97.2 and it was determined that the flood waters will be effective in about 50 hectares of the area.

Abstract: Recently, more attention has been focused on the utilization of food processing by products and wastes, as well as under-utilization agricultural products. Some physical and chemical properties, mineral contents and fatty acid composition of apricot kernel and oils were determined. The oil yields from kernels changed from 42.2% to 57.2%. The crude fibre contents ranged between 4.06% and 7.63%. In addition, crude protein contents ranged between 15.1% and 24.2%. While the peroxide values of kernel oils change between 0.834 meq/Kg and 8.294 meq/Kg, acidity values ranged between 0.279% and 0.700%. The main fatty acids in apricot kernel oils were oleic, linoleic and palmitic acids. Oleic acid contents of kernel oils varied between 53.06% and 70.90%. On the other hand, linoleic acid contents ranged between 21.43% and 35,67%. As a result, the present study showed the apricot kernels of the researched species of apricot kernels from Turkey are a potential source of valuable oil which might be used for edible and other industrial applications.

Abstract: Water extracts at the concentration of 0.5, 1, 2, 3 and 4%, of propolis were prepared and investigated for inhibition of Alternaria alternata, Aspergillus niger, Aspergillus parasiticus, Botrytis cinerea, Fusarium oxysporum i.sp. melonis and Penicillium digitatum in culture media. The concentration of 4% was the most inhibitory of 5 concentrations studied. Microorganisms the most effected from all the concentrations among tested fungi were Alternaria alternata and Penicillium digitatum. The concentration of 4% of propolis extract showed more than 50% inhibition against all tested microorganisms. Se prepararon extractos acuosos de propóleos a concentraciones de 0.5, 1, 2, 3 y 4%, estudiándose en nnedios de cultivo la inhibición por estos extractos de Alternaria alternata, Aspergillus niger, Aspergillus parasiticus, Botrytis cinerea, Fusarium oxysporum f.sp. melonisy Penicillium digitatum. La concentración más inhibidora de las 5 estudiadas fue la del 4%. Los microorganismos más afectados entre los hongos analizados, para todas las concentraciones, fueron Alternaria alternata y Penicillium digitatum. La concentración del 4% de extracto de propóleos mostró más del 50% de inhibición frente a todos los microorganismos estudiados.

Abstract: The antioxidant activities of methanol extracts of propolis were tested in natural olive oil stored at 60 oC. The concentration of extracts in olive oil varied from 0.02 to 0.08%. Extracts at 0.06 and 0.08% concentrations had better antioxidant activity as compared to butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) at 0.01% levels. The greatest antioxidant activities were exhibited by propolis balsam extract at 0.08% levels. lt can be said that the antioxidant activity of propolis increases with concentration. This product is considered as a new source of natural antioxidants. Se ha ensayado las actividades antioxidantes de extractos metanólicos de propóleos en aceite de oliva almacenado a 60 oC. La concentración de extractos en aceite de oliva varió desde 0,02 a 0,08%. Los extractos con concentraciones del 0,06 y 0,08% tuvieron una mayor actividad antioxidante comparando con el hidroxianisol butilado (BHA) y el hidroxitolueno butilado (BHT) a concentraciones del 0,01%. Las mayores actividades antioxidantes se encontraron en extractos de bálsamo de propóleos a niveles del 0,08%. Puede decirse que la actividad antioxidante de propóleos aumenta con la concentración, constituyendo una nueva fuente de antioxidantes naturales.

Grasas y Aceites , 1999,
Abstract: The antioxidant activities of chloroform and methanol extracts of rosemary (Rosmarinus officinalis L.) were tested in natural olive and sesame oils stored at 55 °C, by measuring peroxide values after regular intervals. The concentrations of extracts and citric acid had been used as 1% and 2%. The extracts (except for 12,16 and 20 days in storage of olive oil) exhibited high antioxidant activity compared with control sample in olive and sesame oil. Antioxidant effects of both extracts and citric acid levels in olive oil showed statistically different after from 4 days of storage (p < 0.01 ). The most effective concentration on sesame oil during storage had 2% chloroform extract. Furthermore, especially 2% concentrations of both solvent extracts of rosemary shown significantly antioxidative activity in compared with citric acid on sesame oil. Se determinaron las actividades antioxidantes de extractos de cloroformo y de metanol de romero (Rosmarinus officinalis L.) en aceites de sésamo y de oliva almacenados a 55 °C mediante medidas de los índices de peróxidos a intervalos regulares. Se utilizaron concentraciones al 1% y 2% de extractos y ácido cítrico. Los extractos (excepto para los días 12,16 y 20 de almacenamiento de aceite de oliva) mostraron una alta actividad antioxidante comparados con la muestra control en ambos aceites. Los efectos antioxidantes de ambos extractos y los niveles de ácido cítrico en el aceite de oliva tuvieron diferencias significativas después de 4 días de almacenamiento (p < 0.01). La concentración más efectiva en aceite de sésamo durante el almacenamiento fue del 2% en extracto de cloroformo. Además, especialmente concentraciones del 2% de ambos extractos de disolventes de romero mostraron una actividad antioxidante significativa en comparación con el ácido cítrico en aceite de sésamo.

Abstract: In the Ottoman Empire, the right of real estate property ownship by foreigners began with the law of “Tebaay- Ecnebiye’s Emlake Mutasarr f” on 8 June, 1868 and it continued until the republic period. But it is understood that they had the acquisition of real property ownership illegally before the passing date of the law. At the beginning of the twentieth century, in Amasya, in the centre town and Asibey, Tuzsuz and Kutu villages connected to Varay, the citizens who were German owned the real estate properties.In Amasya, although German citizens aimed to change the region to a colony city with their economic, political and religious politics which they were following with the support of Germany and Europeans, they couldn’t succeed. During that period they supported the economy of the region with the small industrial enterprises they opened and the agriculture and animal raising they were doing on the farm which they opened in the rural area.

Abstract: It has been indicated in the recent economic literature that the accountability of monetary policies is the most significant variable determining the effectiveness of applications. Accordingly, transparency in monetary policy becomes the most important factor for Central Banks. Thus, asymmetric distribution of information between Central Bank and other economic units becomes a significant problem requiring to be solved in order to reach the efficient monetary policy. From this starting point, the study aims to analyze the basic resource of asymmetric information problems. We deal with the asymmetric information between Central Bank and other economic units in the framework of three resources. These are the deficiencies of information concerning the aim of policy, the transmission mechanism of policy and the data sets realized in process of policy application. Also, we will evaluate the policies of Central Bank in Turkey, determining the solutions for problems indicated in this study, in the framework of strategy towards Inflation Targeting
