Öğe Social housing production in terms of constructive demolition and quality of life: the example of ıstanbul(Aksaray Üniversitesi, 2017) Bodur, Alper; Dülgeroğlu Yüksel, YurdanurThere are widely different characteristics in the literature, as well as common features related to the concept of quality of life. In urban life, the quality of life is determined by the interaction of social, economic and physical environment and is directly related to the practices of central and local decision makers. Today, through the state and municipalities, social housing is being produced to solve low-income families' housing problems and to improve the quality of life in general. The purpose of this study is to investigate the effect of the housing production based on the slum dwelling on the quality of life of households. A total of 506 surveys were conducted in 3 districts to assess the quality of life of residents in İstanbul. Accordingly, living situation (individual well-being, quality of life), physical (housing, shelter), environment (habitat, urban infrastructure), social (neighbourhood relations, family relations), economic (business, employment, income, indebtedness), access to services (transportation, municipal services) and 7 indicators, including general factors of life quality were identified. As a result of this study, the improvement of the quality of life of displaced slum dwellers and the improvement of the communication and communication ways of slum dwellers and decision makers are proposed.Öğe An investigation on the soil stabilization with waste tyres materials in granular soils(Aksaray Üniversitesi, 2017) Ordu, Ertuğrul; Biçer, Perihan; Ordu, Şeyma; Abanozoğlu, Emine GamzeThe aim of this investigation is to research the improvement of sandy soils with additive materials. California Bearing Ratio (CBR) is commonly used to determine the characteristics of sandy soils which are improved by using additives. The CBR test estimates behavior of subbase and granular layers for flexible superstructures. Waste shredded tires are used as additives in accordance with the purpose of this study. A great majority of materials, which are considered as wastes in the world, consist of recyclable materials. Recycling these materials is imperative for being able to preserve environmental and natural balance, minimizing the damage inflicted upon nature and also for the country’s economy. The improvement of ground with additive materials has been widely used since it is more economical than other stabilization methods. Recently, usage of industrial waste materials as additive materials has become popular. Investigations on utilization of waste tires in geotechnical engineering are being carried not only in our country but also in the rest of the world.Öğe Electronic structure and binding energy of spherical quantum dot(Aksaray Üniversitesi, 2017) Yılmazer, Fatma; Yakar, Yusuf; Çakır, Bekir; Özmen, AyhanIn this study, we have calculated the energy states and the wavefunctions of the spherical quantum dot with finite and infinite confining potential. In addition, we have investigated the binding energies of the ground and excited states of the spherical quantum dot as a function of dot radius. In order to calculate the energy eigenvalues and the wavefunctions Quantum Genetic Algorithm and Hartre-Fock Roothaan method have been employed. The results show that dot radius and confinement potential has a great effect on the energy states and binding energies. In large dot radii, the effect of confinement potential on energy states is disappeared and energy states go to the energy values of hydrogen atom.Öğe Investigation of static and dynamic behaviour of mersin aksifat dam(Aksaray Üniversitesi, 2017) Sünbül, Ayşe BengüIn this study, the settlement behavior of Aksifat concrete faced rock-filled dam was analyzed, during both period of construction and its water retention. In order to determine total displacement and stress distribution, two-dimensional strain analyses were performed using PLAXIS program based on the finite elements method. The material parameters of the dam were obtained from geotechnical reports, literature studies and the well logging data carried out within the scope of the project. The linear elastic material model was preferred for the bedrock in dam modelling, while the Mohr-Coulomb (MC) model was used for the rock fill, rock foundation and filter sand-gravel. Considering the seismotectonic features of the dam site, the Mw 5.7 Upland California earthquake with a maximum acceleration value of 0.24 g was utilized in the dynamic analysis. In the static analysis, the maximum settlement value was observed in the middle of the dam body fill and in the crest. The maximum value of settlement was computed at the top of the dam body. According to slope stability analysis; the static slope safety factor is greater than 2.0 which indicates that the slope stability is in balance. In the dynamic case, the value of the safety factor is reduced to the value of 1.3. This result indicates that the slope is in equilibrium whereas the slope stability tends to decline if the earthquake acceleration value increases. In terms of 2D deformations and the state of slope stability under seismic forces; the Mw 5.7 earthquake with a maximum acceleration value of 2.4 g will not produce any risk based on the finite element model of the dam used in this study.Öğe Stress analysis of different metal combinations under different temperatures with hybrid joints(Aksaray Üniversitesi, 2017) Özkan, Emrullah; Aldaş, KemalIn this study, the stresses on various bonded joints which made from different sheet metals were investigated by using finite element method. The bonded joints planned as double-pin connection joints and adhesive bonded joints. Six different material combinations were used in joints. ANSYS finite element software was used for analysis, modelling and solution. The models were designed as 3D. The stresses which applied temperature load with tensile load to joints were investigated. As a result of studies, the compression stresses in the models got high values and reached the highest values at X-axis direction. Furthermore, there were stress concentrations around the pin hole. Therefore, it can be easily seen that there may be bearing damage around stress zone.Öğe Determination of fatty acid composition and phenolic content of seed oils of cappadocia region grape varieties(Aksaray Üniversitesi, 2017) Seçen, Selçuk MustafaThe grape (Vitis vinifera) from the Vitaceae family is the most grown fruit species in the world. Turkey has an important place in the world wine-growing due to favourable climatic conditions. The Cappadocia region is among the most important regions in Turkish wine production. The most grown varieties in this region are Emir and Dimrit grapes. Grape seeds are a by-product of the wine-making industry and fruit juice. Most of the total amount of grapes is used in wine making. In a few weeks of the harvest season, around 10 million tons of grape seeds are emerging in the world. Grape seed oil contains omega 6, which is essential for omega fatty acids, at a high rate and also they are rich in polyphenolic compounds with strong biological effects. Due to the fatty acids and phenolic content of these products, it is aimed to be a new food source for human nutrition and at the same time to contribute to the reduction of factory product costs. The highest fatty acids identified in all varieties were linoleic acid (C18: 2), followed by oleic acid (C18: 1), palmitic acid (C16: 0) and stearic acid (C18: 0). Total phenolic substance content ranges between 70 and 84 (g GAE/kg extract) among the varieties. The phenolic content of the Dimrit grape seed is higher than Emir Grape seeds. According to these results, the oils of Cappadocia grape varieties Emir and Dimrit can be proposed as a new food source for human nutrition at the same time to contribute to the reduction of factory product costs.
