Investigation of concrete barriers with recycled rubber, steel slag and roof tile

Kurar, Ali

The purpose of aggregating rubber is to increase concrete’s flexibility, elasticity, and capacity to absorb energy. In some application of concrete, it is desired that concrete should have low unit weight, high toughness and impact resistance. Although concrete is the most commonly used construction material, it does not always fulfill these requirements. In order to improve elastic properties of concrete and recycle the waste materials, new applications have been realized recently. One of these applications is the utilization of discarded tires in order to use together with aggregate. ...Daha fazlası

Urban regeneration strategies for supporting social sustainability of Roma community: Izmir-Ege neighbourhood urban regeneration project

Cin, Mehmet Melih

Urban regeneration greatly affect marginalized groups both across the world and in Turkey and therefore it is a hot topic in the public discussions of urban context. One of those marginalized groups are Roma communities. Their neighborhoods, particularly inner urban areas, face social and physical decay due to discrimination against Roma communities. To address these social and physical problems, urban regenerations projects have been launched in Turkey in the name of improving life standards of Roma citizens. However, implementations could not go further than improving physical conditions of ...Daha fazlası

Fuzzy logic modelling of sediment transport in annulus

Müftüoğlu, Tevfik Denizhan

The understanding of sediment transport with fluid in pipes is one of the important issues in hydraulics engineering. If the fluid velocity is lower than a critical value, a stationary cuttings bed develops, which may cause excessive head loss. In this study, a Fuzzy Logic (FL) model is developed to estimate stationary cuttings bed thickness inside the annulus. Experimental data is collected from literature in order to train proposed models. Results showed that the cuttings bed thickness could be estimated using the developed model with a reasonable accuracy when compared with the experimental ...Daha fazlası

Audiometer device design with integration of different sources = Farklı kaynaklara entegre işitme cihazı tasarımı

Uzun, Yiğit Ömer

Audiometry is the technique to identify the nature of hearing loss and to determine the threshold of hearing by recording responses of the patient after presenting him with auditory stimuli with varying intensity levels. There are different audiometric techniques and procedures used for achieving this. The vast majority of medical devices found in the marketplace as a commercial product for the field of audiology have been developed for clinical limited testing. These devices cannot be used for purposes other than those specified by the manufacturer. This has serious limitations in the experim ...Daha fazlası

Group effect in axially loaded chemical anchors embedded in low strength concrete

Arslan, Tolga

The use of chemical anchors for the connection of existing structural elements with the new elements during strengthening of existing structures is quite a preferred method. Since in our country, chemical anchors are being widely used for repair and strengthening works, there should be a standard of design and application on this topic. Up to now, research done on the topic of chemical anchors, are mostly carried out on concrete blocks of compressive strength 20 MPa and higher. Since parameters such as distance from the edges, embedment depth and group effect were mostly ignored, the re ...Daha fazlası

Evaluation of effectiveness of cold atmospheric plasma treatment methods for prevention of ventilator-associated pneumonia

İbiş, Fatma

Hospital-acquired infections (HAI) (nosocomial infection) are serious health problems that occur when person acquires infection during stay in a hospital for causes other reasons than that infection. Colonization of microorganisms pave the way for deaths, in detail, Ventilator Associated Pneumonia (VAP) is remarkable in terms of mortality accounted for 15% of nosocomial infections. Ventilator associated pneumonia (VAP) is common a disease, especially among patients that are on connected ventilators in intensive care units. It is defined as the pneumonia, in which occurs in at least 48 h ...Daha fazlası

Evaluation of passive building design parameters for Izmir city

Güçü, İlker

The housing sector is one of the largest sector responsible for energy consumption in the world and Turkey. Sustainability is an emerging issue as energy related problems arises throughout the world. The sustainable sources are both clean energy sources and mostly renewable. Therefore, especially in terms of economy, these new energy sources are important opportunity for countries dependent on other countries energy. Turkey is rich in sustainable resources and especially Izmir province has good potential in terms of solar, wind and geothermal energy which are the most important sustainable sou ...Daha fazlası

A preliminary offshore wind energy potential study for bay of İzmir: Quantifying the airflow distortion on local ferryboats for adjustment of wind data by 3D CFD analyses

Güngör, Şahin

Humankind have an interest to obtain marine meteorological data for decades, therefore, constant and mobile meteorological stations have been used for the correct measurements. These meteorological data include wind speed and direction, sea surface and air temperature and cloud cover. Ship-mounted anemometers have been used for meteorological observations, obtaining the wind speed data and climate change analysis. Wind data are especially gathered and reported by Voluntary Observing Ships (VOS). World Meteorological Organization (WMO) created the VOS program to ensure reporting of the wind dat ...Daha fazlası

Characterization of Clay brick materials produced with red mud and nut shell wastes for building applications

Çam, Ata Sadık

In this study, clay based brick with micro pores was developed for thermal insulation in the building materials. Turkey produces about 70% of the world hazelnut production. The aim of this thesis is to reduce the thermal conductivity coefficient by adding organic waste (hazelnut shell) into clay mixture to form porosity during firing of clay bricks. Moreover, it is to maintain the similar mechanical properties by adding inorganic waste (red mud) into clay mixture. The development of a highly porous bricks with applicable mechanical strength will contribute to save energy in the building ...Daha fazlası
